0 WBUR Series: Living With Lyme

On June 26, 2012, WBUR, Boston's NPR (National Public Radio) station, 90.9, began publishing a series, "Living With Lyme", on their website.

The series of articles are accompanied by free downloadable podcasts and sometimes photos and slideshows. In addition to these articles, a live streaming video discussion on Lyme disease was broadcast on June 28 and is available online in its archives.

Additional Lyme disease related articles continue to be published on WBUR after the initial series was posted.

Here is a comprehensive list of all the articles published in the "Living With Lyme" series, from the oldest to the newest post:

For a series on Lyme disease, it is surprising how few patients have left comments on a number of these posts to date. It's been my observation that most of the time, patients participate in commenting on articles about Lyme disease and ticks far more frequently than this series has been responded to so far.

There are a few exceptions, such as the vaccine thread, which I commented on some days ago and which is still receiving more new comments. Sometimes the comments are more informative than the article itself, so they are worth a look. (Other times, they are educational only as a magnifying lens under which one can view other people's psychology... use your judgment, do your own research, and weigh the evidence linked to what people have to state.)

Here is the link to the Special Lyme Disease Panel Discussion (online streaming video):
http://www.wbur.org/2012/06/28/lyme-disease-panel

Panelists include:
  • Dr. Thomas N. Mather, a.k.a. the TickGuy, conducts public education programs on tick-borne illnesses
  • Rep. David Linsky, sponsored the bill that created a state commission on Lyme disease
  • Dr. Sheila Statlender, a clinical psychologist and advocate for Lyme disease patients
And just today, an additional article was posted about tracking Lyme disease:

A lot of thought-provoking articles to read at WBUR, with some thought-provoking comments in response. Check it out...

6 Health Matters Magazine And Lancet Anti-Science Lyme Disease Rebuttals

I wanted to point out two noteworthy online venues which are discussing Lyme disease as well as chronic Lyme disease - one article and a series of rebuttal letters which have been circulating around the Lyme disease patient community recently.

The first venue is Health Matters, an online magazine in the UK which is edited by Steve Iliffe, a professor at the University College of London, and Paul Walker,  an independent health consultant who worked for the NHS for many years.

This month, Health Matters published part one of an article by Kate Bloor on Lyme disease, "Falling Through The Gap?: Part One: Lyme Disease Prevention In The UK."

The article does not focus on the controversy around chronic Lyme disease but instead goes straight to the roots of Lyme disease by asking about which agencies and institutions in the UK are responsible for educating the public on prevention of tickborne illnesses and how well this job has been done to date.

Quoting Kate:
"Approaches that only target those in traditional high risk groups, may not reach far enough. New research shows that one in five people diagnosed with Lyme became infected either in an allotment, park or garden and one in five patients was infected abroad. These are not normally considered high risk areas or high risk activities."
Any program for prevention should be designed to reach all those groups who are found to be at risk and not some fraction of them, and should include prevention where substantial minority groups are at risk.

Kate also included this useful bit of statistical information:
"A survey of GP’s showed that 72% reported using the wrong method of tick removal, of the surveyed councils, only 7% provided information to staff, and only 7% claimed to have information for the public on their website."
From the research I've read from Russia, one of the major causes of infection from tick bites stems from improper removal of the tick. Every effort should be made to carefully remove the entire tick including the head and mandibles, without placing pressure on the tick's abdomen/gut. This will lessen the odds of contracting an infection greatly. Here, citing that 72% of doctors removed ticks incorrectly is very concerning; doctors are the front line for treatment and should be removing ticks properly nearly 100% of the time.

That regional councils would not have their own staff education and education for the public in place is also important to note, and I have to wonder how much those who have been bitten by ticks in these areas have informed the councils on their experience and requested more warnings to the public on tickborne illnesses. To me, it seems like it would require a small amount of effort and money invested in education to help prevent more people from being bitten.

The rest of the article outlines how prevention is being managed (or not) by various organizations, the educational strides being made by patient advocacy organizations such as Borreliosis and Associated Diseases Awareness UK (BADA-UK), and the need for national and local government health agencies to make tickborne illness a priority.

More here, at the link: http://www.healthmatters.org.uk/?p=1203



The second venue I want to mention is The Lancet, which has recently published a series of rebuttal letters in response to an opinion piece posted last year, "Antiscience and ethical concerns associated with advocacy of Lyme disease" (abstract only).


  • Stella Huyshe-Shires, chairperson of Lyme Disease Action, writes about how the situation Auwaerter and his coauthors outline in the US is different from that which is experienced in the UK in regards to Lyme disease prevention, education, and treatment. She focuses on patient advocacy group's drive for awareness and evidence-based medicine to treat patients, and she mentions that the British Infection Association is now collaborating with LDA (UK) and a Department of Health funded body, the James Lind Alliance, on documentation of the uncertainties in treatment and diagnosis of Lyme disease.

  • Christian Perronne, of the Infectious Diseases Department of the University of Versailles-St Quentin, France, points out the high variability and sensitivity of serological tests for Lyme disease, how tests do not account for strain varieties, and that other microbial infections may mimic that of Lyme disease. He points out that syndromes of an unknown cause should no longer be referred to as being chronic Lyme disease, and should be investigated for other microbial and non-microbial causes using an open-minded scientific approach.

  • Carl Tuttle, of Hudson, New Hampshire, USA, wrote about how his experience of Lyme disease did not seem to match that of Auwaerter's experience, given how many people he knows have suffered serious symptoms with Lyme disease that was not diagnosed early - whereas Auwaerter indicated Lyme disease is easily diagnosed and treated. He mentions the inadequacy of serological testing and how it can lead to late stage cases which went undiagnosed and untreated, and how legislation has been passed in several states which protect doctors who treat Lyme disease patients with long-term antibiotics. He asks if the IDSA is correct in its position, then why is there so much legislation being passed which protects doctors who offer long-term antibiotic treatment?

  • And lastly, Auwaerter et al offers a response to these rebuttals here:
    http://www.thelancet.com/journals/laninf/article/PIIS1473-3099(12)70056-7/fulltext.

    Auwaerter et al state that a huge percentage of patients are being improperly diagnosed with chronic Lyme disease by alternative practitioners when these patients have another condition. They point out that serological testing is reliable, and evidence that testing is unreliable would be needed by Mr. Perronne and Mr. Tuttle in order to support their position. Auwaerter et al point out that the current guidelines stand based on independent scientific review and that "Vague symptoms such as chronic pain, fatigue, and neurocognitive complaints are poorly understood by modern medicine but are the focus of this debate." (Ed: The last full paragraph of this response is as long as the previous two put together and is comprised of nothing but a list of stated possible conflicts of interest.)


Comments:

While I agree with a lot of what Ms. Huyshe-Shires had to say, I would like to step away from the argument that "Lyme disease in ______ is different because it's different here".

I've heard this before, and this argument has been made to try to distance European patients from those in the US, with an underlying belief that since European strains are different, that diagnosis and treatment should be determined using European scientists and research - not that of American based IDSA. Fine, but then I will argue that since Europeans also contract Borrelia burgdorferi that they should come up with diagnostic and treatment methods for the US as well!

Scientific research to date has shown that Borreliosis is Borreliosis, whether it is caused by Borrelia burgdorferi, Borrelia afzelii, Borrelia garinii, and a number of other strains. The symptoms produced by these organisms may differ somewhat from one locale to the next, but many have the potential to cause neuroborreliosis, and indeed, even those with a most conservative view of the Lyme disease controversy have stated that there has been too much emphasis on Europe having more neuroborreliosis and different symptoms when the situation is that clinical presentations in the US have been very similar to those in the UK

Receiving an early diagnosis and treatment matters regardless of where one is in the world and which strain they have.

I can relate to Mr. Perronne's position, to some degree. I don't think this is a heterogeneous condition - nor was it from the start even if just basing it on those who have had tick bites - since a number of ticks are coinfected with pathogens other than Borrelia burgdorferi/afzelii/garinii. I think it's possible some patients have a different infection which they contracted through a tick bite or perhaps even a tick bite made them more susceptible to a new, undefined infection. More research is needed to determine why this group is heterogeneous, and to study those with a definite history of a tick bite and persisting symptoms very closely (regardless of serological test results) as their own separate group.

Mr. Tuttle's remarks reflect the fact that regardless of what side of the Lyme disease controversy you stand on, people are suffering a lot and heated debates on the state level end up weighing in on the side of the patient. Access to extended treatment is winning - whether the IDSA approves or not.

Auwaerter et al's response, to me, is predictable and to be expected. It would be appreciated if one day they were to focus more on the content of Mr. Perronne's position and join him in it by finding a way to initiate research which directly helps patients who are suffering with persisting symptoms and to stop spending an inordinate amount of time focusing on whether or not certain doctors and patients promote pseudoscientific practices and beliefs. They've already made it quite clear to The Lancet and the public what their position is.

One has to face reality here: If some alternative to current treatment practices is discovered which is safe and effective, patients will use it. In the meantime, patients who are suffering greatly will try any of a number of drugs, antibiotics, herbs, and supplements which are available in order to get well regardless of the IDSA's position on their condition and its treatment.

Whether these attempts to relieve symptoms are scientifically backed or not is irrelevant to someone who is seeking relieve pain and is nearly (if not completely) on the verge of suicide with pain. It is this human element of suffering which Auwaerter et al do not seem to want to contend with and address in a compassionate way - nor in a clinical, scientific way by either engaging in research which directly resolves the controversy or by finding the treatment of all treatments based on their own hypothesis of what causes persisting symptoms.

Patients with persisting post treatment Lyme disease symptoms have often tried mainstream approaches to treating their conditions when they were diagnosed with something other than chronic Lyme disease - only to either experience no improvement or even experience a significant worsening of their condition. The use of steroid-based drugs used for treating rheumatic conditions has been one such example of where patients with chronic Lyme disease have tried them based on an apparent diagnosis of a rheumatic condition - only to get sicker and become more symptomatic. Why is that? Someone needs to research this, too.

At some point I need to write a detailed scientifically cited response to Auwaerter et al's original letter to the Lancet instead of the rant I wrote in response to the abstract alone last year. At the time, I was too personally offended that I and my condition were equated with pseudoscience and my offense led to ranting rather than a rational, objective calling out of each point in the full text with a substantiated counterpoint of my own. 

It's difficult to be without bias. As a person suffering with the fallout from Lyme disease and Babesiosis, I cannot be completely without bias no matter how hard I try. But I can try to read the scientific arguments and research that different parties put forward and weigh them independently of how rotten I feel. It is possible, even if at times difficult. 

In the end, I genuinely want someone to just figure out what has brought me to the level of suffering I've experienced over the past several years - even if in some of that figuring out the cause turns out to differ from that which I've suspected. Fine. Just find it, and find a treatment that gets me back to my old self.

0 The Wall Street Journal On The Increase Of Tickborne Diseases

Today, Laura Landro of the Wall Street Journal published an article in its Life & Culture section on "This Season's Ticking Time Bomb: Warm Weather Means Ticks Will Be Out Early; A 'Horrific' Season for Lyme and Other Diseases."

It sounds like a sensationalized piece from the title at first - but it's not. It's straightforward reporting on how this year the number of tickborne diseases will be on the rise due to earlier warm temperatures and how to protect your yourself and your family through interactive advice.

Laura's article outlines the typical topics around Lyme disease: symptoms, the difficulty of early diagnosis and treatment, the rising number of cases reported to the CDC over the past decade, and the steps one can take to prevent contracting Lyme disease.

There is also mention of a CDC study on the use of sprays to limit tick population and how a Connecticut scientist sets Japanese barberry on fire to remove it as a source of ticks' sheltering habitat.

For more information, check out Laura's article on the WSJ here:

In addition to this article, Laura Landro also wrote a blog entry in the Health section, "Doctors Clash Over Best Treatments for Lyme Disease", which discusses the IDSA's treatment guidelines approach (short, and possibly not sweet) and ILADS treatment approach (in for the long haul) for patients with persisting symptoms.

In the blog, Paul Mead of the CDC, Leo J. Shea III of ILADS, and Kristin Schofield, founder of a central New York chapter of the Empire State Lyme Disease Association, are all interviewed.

0 More On Lyme Disease In Australia On The Today Tonight Show

There's been increased interest from my readers in learning more about Lyme disease in Australia, so I decided I would offer an update on the situation for everyone including my northern hemisphere readers who are interested in new developments there.

Last week, the Australian television news show, Today Tonight, posted a segment on Lyme disease in Australia and how it has become a controversial issue as a number of Australians who have never left the country were bitten by ticks and developed symptoms very much like those of Lyme disease.

As far as it is known, the bacteria which causes Lyme disease has not been detected in ticks in Australia - unless the researchers mentioned in the previous episode of Today Tonight which was covered here have finally discovered it.  Without their official announcement, though, it has been the situation that cases of Lyme disease within the country which have been confirmed were attributed to infections acquired overseas. Any recent reports of Lyme disease contracted within Australia have become controversial.

This week, Today Tonight has posted another segment about a man, Robert Sotur, who became ill on the job after numerous tick bites and won a government workmans compensation case due to an infection with Lyme disease.

This is pretty notable because he received compensation for a disease that the Federal Government, the Australian Medical Association, and Australian State Governments all say doesn't exist in Australia.

View the video of the show and transcript here: http://au.news.yahoo.com/today-tonight/health/article/-/12972227/lyme-disease-compensation/

A lawyer, David Jones (yes, seriously, David Jones - wonder how much tiresome joking he gets about that name), who is working on behalf of over fifty patients who never left Australia yet have come down with Lyme disease-like symptoms in Australia made this statement to Today Tonight:

"There needs to be an acceptance that there are many people within our community that are having symptoms that are Lyme or Lyme-like, and Governments need to take these people seriously. They need to commission the research, and they need to determine whether or not this disease, or a disease like it, exists here in Australia.”

He's right. If one man has won a workmans compensation case within Australia for falling ill after tick bites, there will likely be others. More than fifty, judging from his caseload alone. But there will be far fewer cases if the research is done to find the causative agent of this disease and to treat people for it as soon as possible.

If it is a bacterial agent, then unlike Ross River Virus and other viral infections which are more well known throughout Australia - early treatment can prevent more serious symptoms and potential permanent damage, and in the worst case scenario - death, as in the case of Karl McManus.

Given the limited amount of recent surveillance and examination of ticks for an indigenous spirochete that could cause a condition similar to Lyme disease - if not the potential importation of Borrelia spirochetes from neighboring Asia - it is not clear what reality is. The last major study to discover if Australian ticks harbored a spirochete similar to one that causes Lyme disease was conducted over 15 years ago. The situation may be different now.

Australian support groups for patients with tickborne illnesses have not only reported being bitten by ticks and falling ill afterwards - some have also reported infestations of bird mites preceding the onset of their symptoms. If this is the case, there may be more than one pathogen and more than one vector responsible for an overlapping set of symptoms in patients. Careful and thorough research is needed to sort it out.

My advice to any Australians reading this is whether or not the controversy of the existence of Lyme disease in your country is resolved soon that you do what you can to protect yourself from tick bites. Learn how to properly remove a tick to minimize the risk of infection, find a place to send your ticks for analysis, and educate yourself about the spectrum of symptoms which are related to ALL tickborne diseases and not just Lyme disease.

Tularemia was discovered in Tasmania last year and there is evidence beyond a doubt of its presence. Lyme disease now appears to be a possibility. And then there are those mosquito-borne and tickborne conditions of which many Australians are already familiar with such as Ross River Virus, Barmah Forest Virus, Tick Typhus, and Tick Paralysis - none of which you want if you can avoid them.

See a doctor if you suspect you have contracted a tickborne infection - remember, it may or may not be Lyme disease and treatment will be different for coinfections. But do go as soon as possible in order to prevent serious and potentially long-lasting complications.

And last but not least:

Petition your government, CSIRO, and local universities to do more research on tickborne illnesses including Lyme disease. Make sure you have your own homegrown research teams that will investigate the possibility of Lyme-like illnesses from pathogens transmitted by both bird mites and ticks. Ask Australian scientists to pave their own path and to not feel obliged to model all their investigations and guidelines for treatment based on those found in the northern hemisphere until it is more certain what is happening. In the meantime, treatment will probably be empiric and based on history, symptoms, and test results.

2 More Thoughts On Birds, Cool Shirts, And My Evil Twin?

More On Ticks And The Atlantic Flyway:

I continue to think about the role of birds carrying ticks to different regions and how Lyme disease (and other tickborne infections) could be spread that way. But much as I found the overlay map I posted earlier this week to be intriguing, I don't think that tracking infected ticks on birds is as simple as following major and principal flyways - even though that could be a reasonable point to start an investigation.

Yale has already done some work in this area, and I have no idea whether or not they've factored the results of this publication, "Do birds affect Lyme disease risk? Range expansion of the vector-borne pathogen Borrelia burgdorferi", into their recently published Lyme disease risk map.

It's important not to discount the role of birds here:
"Although the role of birds in B burgdorferi transmission dynamics is often discounted, data compiled from published studies indicate that the majority (58.6%) of bird species that have been evaluated are capable of infecting larval I scapularis with B burgdorferi. We estimated – for two bird species – that the number of individual birds required to produce one infected I scapularis larva is as low as three, and we conclude that bird-mediated tick movement is an important factor in the range expansion of both I scapularis and B burgdorferi."
Read More: http://www.esajournals.org/doi/abs/10.1890/090062

There are certain behaviors birds engage in and seasonal activities which would lead to a higher likelihood of birds contributing to the spread of Lyme disease on the ground. Specific kinds of birds would be more likely to contribute to infection spread than others - for example, I suspect birds which build their nests on the ground and are ground-based hunters are more likely to contribute to infected tick populations than birds which build their nests in trees. Also, some birds feast on ticks (such as guinea fowl) and they will lower local tick populations.

These are just a few examples - there are many more. I imagine there is no simple algorithm for determining the role for birds in spreading infection. I don't know what all the factors are which would contribute to the spread of Lyme disease via birds, and it's something I continue to look into because it does play an important role in surveillance and determining how infection could spread through different vectors.

Cool Lyme Disease T-shirts:

While doing a general search for Lyme disease related news the other day, I came across these shirts on Cafe Press:


I think they must have had me in mind as a target demographic, because it's the first Lyme disease related t-shirt that  I've seen which appealed to my appreciation of the TV show, "The Big Bang Theory", and also appealed to my appreciation on word play while mentioning Lyme disease research. It says "More nervous tics than a Lyme disease research facility"- playing on the word "tics" or "ticks".

There are a number of products for sale with this slogan on it (not just t-shirts) at Cafe Press  -  I don't know who is selling them and if they're another Lyme disease patient or not - the product page did not display this information. Check it out if you think it's something you'd like, too.

My Evil Twin?

It's been pointed out to me that I have a doppelganger online named Tom Carolan. He has Lyme disease blog, Tick Borne Diseases Radio, with entries in it which upon reading looked strikingly similar to my own blog at first glance. However, after more examination,  it's clear Tom's blog contains different content and his own unique commentary on the same topics which have grabbed my attention.

(Just so everyone knows, I have no problem with anyone passing on the content I write here as long as you give this blog credit and link to it. That's why I have a Creative Commons license posted at the bottom of each entry - so you know I support a more open source approach to copyright.)

Tom also has a podcast on iTunes on Tick Borne Diseases:
http://itunes.apple.com/us/podcast/tick-borne-disease-radio/id306917344

How about going over there to Tom's site and giving it a good read, and encouraging him to continue to post more podcasts and blog entries? It looks like he has a good thing going on and more content like his would be welcome - particularly more podcasts.

7 The New Tick Map Vs. The Atlantic Flyway: Things That Make You Go Hmm.

[Ed. - Overlay map revised Feb. 9, 2012.]

Well, I guess everyone has seen this map from Yale University by now...


Yes, it is a map of Lyme disease risk areas based on tick flagging from 2004-2007 in the above regions, followed by an analysis of those ticks. No matter where one looked, the odds of a tick carrying Borrelia burgdorferi were 1 in 5 everywhere... So be careful out there, huh?

While it's good to let people know there are transition areas where Lyme disease is up and coming, it's good not to be too complacent if you fall into a green zone. Today's low risk zone can be tomorrow's transitional area, and these maps must be accurately updated in order to reflect reality.

Thing is, I haven't been thinking of this map as regards tick distribution and Lyme disease so much as I've been thinking about this map:


Because there is evidence that ticks' distribution is spread not only by mammals which hug the ground - but can also be spread geographically by birds. 

So look at the above two maps. Now look at this, after I scale and resize them to overlap (somewhat off-bias, but best I could get with different projections):


Questions for my readers:
  • For those of you along the southern principal flyway, how many of you received an infected tick bite near that flyway, either to its north or south?
  • For those of you in northeastern and north central Florida, how many of you received an infected tick bite near that flyway passing over your state?
  • For those of you in eastern Canada, can you tell me if you received an infected tick bite near that flyway by the Great Lakes?

I'm looking at this and wondering a few other things, too, like I think these flyways would end up moving a little further north as global warming progresses - so I would expect a greater distribution of infected ticks further north as time goes on. Is there any way to confirm this is what is happening?

11 Rant: Why Dealing With Lyme Disease Drives Me Crazy. (Part 1)

Note: The content that follows is part one of a personal rant and is atypical of most content as well as context covered by this blog. 

I've been meaning to write this entry for a long time.

Many attempts have been made before this - many which have been scrapped because they neither met my general standards for publication nor managed to convey what I wanted to express.

 But I have to get it off my chest because face it, I've been dealing with this condition and its complications for years now and every so once in a while I've gotta just let it all rip, Camp Other style.

Why Dealing With Lyme Disease Drives Me Crazy

Where do I even begin?

Let's start with the more obvious, from a patient's perspective.

1) Because the lack of early diagnosis and treatment occurred for something which should have been obvious to not only the first family doctor who saw me - but the second one. 

I had a textbook case of Lyme disease: EM rash, history of a tick bite, and symptoms consistent with a Lyme disease diagnosis. I knew the geographic location in which the tick had bitten me because I found the tick within a day of hiking in an endemic area. The state health department and university researchers knew it was an endemic area.

The index of suspicion should have been high, but I was treated dismissively and told that Lyme disease doesn't happen in my state or the area in which I'd been bitten.

Admittedly, I myself did not know how endemic the area was for Lyme disease until after I received my bite and went to my first doctor's appointment. It's after that point when I decided to look it up, and discovered the doctor had made a mistake. People are human and doctors are human and make mistakes, but for me this has been a very costly one - the doctor I saw should have known more about surveillance and epidemiology in the area than I did.

The second doctor had an opportunity to see my larger than 5 cm expanding rash and still thought I just had a sinus infection. When I brought up that I thought I may have Lyme disease, the doctor ran an ELISA -  but this testing was too early to show an antibody response. What the hell, I already had an expanding EM rash - I was treatable on that count alone. Again, a sign of ignorance about the disease, even from a basic IDSA/CDC/State health department point of view.

After having read many other patients' stories about having had a similar experience, I can only suggest that doctors need more education about tickborne diseases and to be more vigilant about immediate treatment as the risks of early treatment are far less than managing complications that come from disseminated and late stage infection.

 2) Because of the lack of a timely and accurate diagnosis and treatment by a family doctor, I ended up seeing an LLMD for diagnosis and treatment.

After my initial research of Lyme disease, of course I came across information about the controversy in Lyme disease and both information singing the praises of LLMDs and how they saved patients' lives as well as information condemning them for their overpriced fees, lack of taking insurance, rude support staff, difficulty in getting appointments, and unproven protocols. I heard both sides from patients. I also got to hear criticisms about LLMDs from some science writers and medical professionals about how their diagnostic and treatment methods were not well supported by science and that LLMDs were only out there to take advantage of the gullible.

I got an earful early on, believe me. But despite hearing the negative reports, I still found myself in the position of having to make my own decision as what to do next and soon, because I was so sick.

I had to do something. I could barely think straight at the time. I was so ill I could barely follow someone else's conversation. I could only read in very short spurts. I was exhausted, in pain, could not work, and could barely take care of myself.

I had to network with people and figure out what I was willing to do. I had to rely on others' suggestions and concerns more than I usually would simply because I had trouble thinking straight. It was rough going.

In time, I realized not all LLMDs were cut from the same cloth and I already knew why I was sick - so controversy or not, I was going to go where I knew someone would help me. If an LLMD was going to treat my Lyme disease and the doctors I'd seen at my supposedly highly rated clinic weren't, I was going to see an LLMD. Simple as that.

At the time, I didn't want to get involved in the controversy at all - even as I felt sympathy for everyone dealing with long term symptoms. I thought that as long as I was treating this infection early that I would be one of the lucky ones - I would take antibiotics for 3-4 weeks and not have to face persisting symptoms.

However... I was wrong. Only I didn't know it at the time. My infection disseminated fairly quickly early on and I was already sicker than others who had acute Lyme disease and received treatment early. I developed symptoms of a coinfection later on that I would not have known to look for or even suspect. The LLMD did suspect this coinfection, then ran tests - for which I was positive - and as a result, I was treated for it and my symptoms improved.

I am still in less pain than I used to be and some of my symptoms completely disappeared from this treatment, so I think there were measurable gains and seeing an LLMD for treatment was the right thing to do when I did it. I genuinely had Lyme disease to begin with - and if two other doctors were not treating it - then someone else damn well was going to treat it.

My question is why did I have to see an LLMD for all of this when a well-trained family doctor should have known from day one what was wrong with me and treat it back then?

Maybe in my case, weeks or a few months of not having treatment or having inappropriate treatment made all the difference in the world for my outcome. The earlier the better, they say. And I could have had that and sidestepped this mess had the family doctors I'd seen earlier on knew what they were looking at and got right on top of it.

3) Because for some reason, having a Lyme disease history is either not calculated into any new symptoms I present to most doctors (both family practice and emergency medicine) and each symptom set I experience is either attributed to something entirely new and separate - or I am told that there is nothing the doctors can do for me (not even palliatively).

Again, I see this response as a lack of education of the doctors in question. I think that doctors have to take into account that even if they themselves do not believe in a chronic infection model of Lyme disease which the Lyme disease patient community supports - that they need to at least consider that the patient in front of them with a history of Lyme disease may be suffering complications related to having had the infection, and to consider the possibility of a coinfection or relapse of a coinfection where symptoms appear to overlap.

If Babesia is a growing problem in our national blood supply and has killed people through transfusions, it seems important to me to rule out Babesia in patients whether they have a mild presentation or a serious one. The risk to everyone's general health is involved.

Sometimes I think it is not just a lack of education which prevents family doctors from dealing with Lyme disease patients. Sometimes it's a matter of fear of not having enough expertise and making a mistake, and not knowing to whom one should refer a patient. If family doctors were better trained to begin with, though, then they could gain that expertise themselves and be the front line for diagnosis and treatment as most patients expect them to be.

Other times, I think part of the issue is that some doctors have decided to overgeneralize about what they read from various medical journals, letters, and reviews, wherein the author states that at least half of those patients claiming they have chronic Lyme disease never had Lyme disease in the first place. Once having digested that nugget, the doctor then may go on to think that a patient who tells them they either have or have had Lyme disease that because it's at least a 50/50 chance the patient never had it in the first place that it is data not worth considering.

Given the growing number of documented Lyme disease cases reported to the CDC annually, I'd like to suggest to these doctors that they nip that thought in the bud and just look at each patient as an individual and consider that their Lyme disease history may play a role in their current symptom set. They don't even have to enter into the controversy to go there.

4) Because of the changing face of the medical profession and doctor-patient relationship in an era of managed care, anyone with a chronic or hard-to-define illness is getting shortchanged these days - and sadly, at times readily receiving a mental illness diagnosis when the evidence for one is weak at best (or at least not the primary cause of their symptoms). 

After reading many different patient forums - not only for Lyme disease, but for conditions like fibromyalgia and CFS/ME or even rare, orphan illnesses which most people do not know anything about - I've seen this happen time and time again: Doctors trying to nail down a diagnosis for a patient within that 10-15 minute appointment window, and when there seems to be "too much going on" for the patient, the immediate suggestion by the doctor is that the patient's condition could be psychological.

Now, I acknowledge that a number of physical symptoms are related to depression and anxiety, as well as chronic stress. And if one is suffering from these conditions, they need to be recognized for what they are and receive proper care. However, I think some doctors are too quick to make this judgment and need more time to listen to patients and create a list of non-psychological physical, endocrinological, infectious, and/or immunological disorders and conditions to test for first before referring patients to a therapist.

Or if the person is obviously psychologically ill, to at least consider a biological basis for that illness or that it may be contributing to it. There is no reason not to run tests while referring one for therapy just to deal with the frustrations of being ill, either - and a caring, compassionate doctor will know how to finesse the situation so that both physical and mental bases are covered without being dismissive towards their patients.

For what it's worth, my family doctor has not diagnosed me with a mental illness. I myself have sought out therapy for depression while dealing with illness - and of the two therapists I have seen, both have told me to keep talking to doctors because it's their assessment I am physically ill and disabled and any depression I have stems from my health - not the other way around.

The biggest problem I have had with being told "it's all in your head" came from ER departments who could not figure out what was wrong with me in the handful of hours that I was there.

5) My treatment has not led to a full recovery or even closer to a life where my symptoms are stabilized.

Some patients within the Lyme disease community have gone off on me for what I'm about to say, but it's an honest assessment about where I am: I have come to accept that I may never regain my former health again and be 100% cured of the symptoms I'm having.

I don't have any expectations that I can return to my old life and do what I used to do and have the same amount of energy I once did. Even if I could be assured of being cured now, there may still be residual damage in my body - plus I am getting older and my body has been deconditioned by years of nearly total sedentary living.

At times I have felt like I've been fed a false hope that I could recover 100% from treatment, because I have certainly tried a lot, above and beyond what the original IDSA Lyme disease treatment guidelines stated. I have not fully recovered, and it's already been several years since I was first infected.

While I do what I can within my limits to try to stretch and improve my health to the degree that I can, I'm aware that there is so much that isn't known about or understood about my condition that it doesn't seem unreasonable to me that I may not get back to my previous state of health before the tick bite.

About the best thing that has helped me was Mepron for Babesia. It helped take care of a number of the most debilitating symptoms I've experienced. But everything else has either resulted in temporary gain or made me feel so much sicker for a longer period of time - that for months at a time, I actually feel much better doing nothing at all.

This is not to say I will never try anything again. It's to say that I want more evidence that the next thing I try is going to make a positive difference and have a good idea of why and how it is going to make a difference. But it seems to me that as time goes on, I still have bad days and less bad days and occasional good ones regardless of what medications or antibiotics I'm taking.

My experience leads me to believe that I either have permanent damage or long term damage that will take years to heal - or that the proper treatment for my condition has yet to be discovered. This is one key reason why I think more research - particularly treatment trials - is important.

6) Because there is a lack of societal and institutional support for someone suffering from my condition, as well as the lack of a streamlined process for acknowledging and supporting how my condition disables me - a condition which should receive official recognition as a disability.

Mainstream medicine has societies for cancer research - multiple societies including ones for specific cancers. It has workshops and support groups for cancer patients. It has programs on nutrition and cooking for cancer patients on site at hospitals and clinics. There are large scale races for the cure and other fundraisers. There are conferences on cancer which some patients are invited to - and some not. And there are many oncologists and oncology staff members and therapists who specialize in dealing with the issues cancer patients face. So on an institutional level, the need for support and education for cancer patients is recognized and accommodated.

When it comes to other doctors' attitudes about oncologists, they do not envy their jobs and have respect for the difficult job they have to do. Being a family doctor, you are more likely going to see minor problems you can fix and not have to watch someone die of cancer before your eyes.  So there is a certain amount of personal and professional respect from many doctors towards oncologists just because of what they have to deal with on a daily basis.

From the perspective of someone who has had post treatment persisting symptoms of Lyme disease (however you name or characterize my condition) I have felt marginalized and that the kind of support I could use has been lacking.

There is nowhere near the infrastructure available for someone with my condition that there is for someone with cancer. If it weren't for some online forums, a few LLMDs, and a few organizations that bend over backwards to recognize that my condition is debilitating - there would not be anyone at all to acknowledge and validate my disability.

I deal with a condition where the doctors - LLMDs - who try to treat patients like me do not receive respect from a number of other doctors, some researchers, and some members of the media. And as patients we will continue to see these doctors not because we are gullible - but because they are actually trying to help us.

If those whom disrespect them have an issue with this, then instead of knocking the doctors who see us and the treatment we undergo, they should make more of an effort to provide patients with a helpful option under their care. We will vote with our feet if you have anything better to offer. And believe me, we are all such big mouths in the Lyme disease community that we would let everyone know if others' approach and treatments really helped us. Even if only symptomatically. Even if it wasn't a cure.

Now, admittedly, there are fewer people who suffer from my condition than who suffer from cancer. But even so, it seems that no matter how many or how few people suffer from a medical condition and/or disability, that there should be a certain baseline recognition, acceptance, and accommodation for that condition or disability. Not just from patient organizations that patients have had to put together from scratch - but from medical institutions, doctors associations, societies, and research groups.

There is something, though, that has troubled me about what makes post treatment Lyme disease (or as the IDSA puts it, "Post Lyme Disease Syndrome") different from other conditions (orphan, or of unknown etiology) that has made me wonder how it has come to be treated as it has been, historically:

Unlike other conditions where the cause is unknown and speculated about, mine does have the distinguishing characteristic of having been triggered by Lyme disease in some way. There is a clear issue of cause and effect here; of some sort of relationship which has already been defined in medical literature.

But people in my situation don't even have the benefit of having the label of "Post Lyme Disease Syndrome" holding significant meaning for them when they apply for disability - even though a number of us suffering with persisting symptoms would be considered to have this condition by some medical professionals.

In the Klempner trial, it was noticed that those most severely affected by this condition had a quality of life and functionality similar to patients with congestive heart failure. This statement was not made by an LLMD (for those whom have issues with an LLMD and may be dismissive about such statements) - this was a statement made by an academic researcher who studied patients suffering with my condition, whatever label you want to apply to it.

Somehow, it seems that whatever I have should be taken more seriously, and there should be more institutional and societal support for it. It shouldn't be a backbreaking effort to explain what ails me - with my medical history, test results, and clinical diagnosis, it should just be accepted as part of my reality and worked with, rather than denied and shrugged off.

0 New Ehrlichiosis Strain Causing Disease In Sweden

Researchers at the University of Gothenburg's Sahlgrenska Academy have discovered a brand new tick-borne infection. Since the discovery, eight cases have been described around the world, three of them in the Gothenburg area, Sweden.

The disease-causing agent is bacteria known as Neoehrlichia mikurensis. This bacterium was identified for the first time in Japan in 2004 in rats and ticks but had never before been seen in Sweden in ticks, rodents or humans.

One notable symptom of the disease - alongside typical tickborne infection symptoms such as fever and diarrhea - is the development of deep vein thrombosis.

Read more here: http://www.sciencedaily.com/releases/2011/12/111206131404.htm

Comment:

It's always prudent to keep in mind that Borrelia burgdorferi (as well as other Borrelia) are not the only bacteria that can be transmitted by ticks. Many different diseases can be contracted - bacteria, viral, and protozoal. One can be bitten by a tick and infected by a coinfection and not be infected by Borrelia at all - though it is more likely in many parts of the world for the tick to be infected with Borrelia as well.

The rule of "if the tick was on me for less than 24 hours, I'm probably okay" is not a real rule. The twenty-hour hour minimum for Lyme disease transmission time was based on limited research, and research on transmission time for many coinfections has indicated far less attachment time is needed for an infection to develop.

0 Review Of The 2011 Lyme and Tick-Borne Diseases National Conference

In October 2011, a national conference on Lyme and tick-borne diseases was held in Philadelphia by Columbia University and the Lyme Disease Association.

Here is a brief overview of the topics presented:

  • Dr. J. William Costerton’s riveting talk on “The Role of Biofilms in Chronic Bacterial Infections” reviewed the history of the discovery of biofilms, demonstrating that these biofilms enable micro-organisms to resist host defenses and antibiotics, enabling infections to become chronic.
  • Dr. Eva Sapi’s talk on “Killing Borrelia – an impossible job?” addressed various mechanisms associated with Borrelia burgdorferi that may help it to survive despite antibiotic treatment.
  • Dr. Jason A. Carlyon’s talk focused on Anaplasma phagocytophilum, the agent of human granulocytic anaplasmosis (HGA). This emerging tick-borne pathogen demonstrates stealth trickery, enabling it to avoid and even subvert immune cells.
  • Dr. Richard Marconi’s talk on “C-Di-GMP” described research demonstrating that the cyclic nucleotide, c-di-GMP, plays a critical role in regulating several important cellular processes.
  • Dr. Chris Earnhart’s talk described work developing a novel next-generation Lyme disease vaccine based on outer surface protein C. Osp C is expressed by all Bb species and strains and is expressed in the human host for several weeks before being down-regulated.
  • Dr. Robert S. Lane gave a brief overview of his research team's long-term studies of the ecology and epidemiology of Lyme disease in California, and then summarized some exciting recent findings regarding the genospecies and genotypes of Borrelia burgdorferi s. l. that infect the western black-legged tick and humans in this region.
  • Dr. Karen Newell Rogers presented a talk about novel ways to target chronic inflammation and chronic immune activation among patients with chronic Lyme disease. The primary controversy with Lyme disease has been whether the disease is the result of long-lasting bacterial infection or whether long-term symptoms result from a post-infectious, uncontrolled autoimmune response.
  • Dr. Robert Yolken’s talk on “Infections and Human Neuropsychiatric Diseases” focused on the Stanley Center’s work at Hopkins which has examined infectious triggers of psychosis.
  • Dr. Josep Dalmau’s talk on “The Clinical Spectrum and Cellular Mechanisms of Autoimmunity in NMDA and other synaptic receptors”. His pioneering work studying anti-NMDA receptor encephalitis shows how an immune response triggered by a tumor (e.g., ovarian teratoma) or perhaps an infectious process, results in antibodies that can attack critical receptors and synaptic proteins in the Central Nervous System involved in memory, behavior, cognition, and psychosis.
  • Dr. John Aucott’s talk on “Early Lyme disease” reported from the SLICE prospective cohort and his Maryland studies.
  • Dr. Reinhard K. Straubinger's talk on “Canine and Equine Lyme Borreliosis” focused on Lyme borreliosis in animals, especially in dogs and horses.
  • Dr. James Moeller presented a talk on “Immunologic aspects of neuropsychiatric illness: Lyme disease as model”.
  • Dr. Brian Fallon presented a talk on “Models of Chronic Lyme Disease”. The talk started with a review of the terms that refer to chronic symptoms and recommendations on how the the IDSA’s definition of Post-treatment Lyme Syndrome could be improved. This talk reviewed the evidence regarding models of persistent infection and/or persistent immune activation.
  • Dr. Andrew Walter reported on Ehrlichiosis and Hemophagocytic Lymphohistiocytosis (HLH) in cases of children diagnosed in Delaware.
  • Dr. Andrea Gaito provided an update on the clinical evaluation and treatment of Lyme Arthritis from an autoimmune perspective. Lyme arthritis occurs in sixty percent of patients with untreated Lyme disease.
  • Dr. Ingeborg Dziedzic presented an interesting (and at times entertaining) overview of how Lyme disease impacts the eye, emphasizing that the eye is in part like the skin and in part like the brain.
  • Dr. Vijay Thadani presented an overview of seizures and non-epileptic seizures, showing videos of both. Brain infections such as Lyme disease can lead to the development of epilepsy.
  • Dr. Steve Bock addressed complementary and integrative medicine approaches to the treatment of chronic Lyme disease.
  • Dr. Elizabeth Maloney addressed studies of antibiotic treatment of Lyme disease, providing a thoughtful and critical review of the literature to identify lessons, gaps, and future research needs.

2 News: Substantial Increase In Tick Activity Concerns Canadian Officials

Good news from Canada about increasing Lyme disease awareness: The Kingston Whig Standard newspaper has written about the record number of ticks residents sent into the health unit for Lyme disease testing and the number of ticks found positive so far.

Excerpt:

"Following a substantial increase in the number of ticks submitted for testing this year, officials with the local health unit hope to draw a bullseye around the issue of Lyme disease in order to prevent a rash of new cases in 2012.

Joan Mays, manager of health protection for the Leeds, Grenville and Lanark District Health Unit, said there have been 568 tick submissions to the health unit so far this year. Of these, she said, 40 have tested positive for the bacteria that causes the disease, with the health unit still awaiting the results of 271 tests."

Health unit officials noted that an extension of warmer temperatures through the season has led to longer tick activity during the year, and more Canadians are becoming aware of Lyme disease and sending their ticks in to be tested so they may find out if they may have the disease.

I find it encouraging that more people are sending in their ticks and health unit officials are taking notice. Lyme disease is in Canada and there is no sign it is going away. This is just one sign of greater awareness - but more early testing for Lyme disease in people would be even better.

5 News: Infected Ticks Found In New Brunswick

Dear Canadian doctors: Yes, Virginia, there IS Lyme disease in Canada. Please step up to the plate and diagnose and treat the growing number of Canadians with Lyme disease. Thank you...

Deer ticks found on Grand Manan

The provincial Health Department recently identified a breeding population of blacklegged ticks, properly Ixodes scapularis, sometimes called deer ticks, infected with Lyme disease at North Head, Grand Manan.

"We only confirmed that in the last week or so," New Brunswick's Chief Medical Officer of Health Dr. Eilish Cleary said in an interview from Fredericton Thursday.

Last year scientists confirmed a similar breeding population in the Millidgeville area of Saint John.

Scientists believe these creatures are moving north as the climate changes, bringing Lyme disease with it, Cleary said.

0 Institute of Medicine Final Report on October 2010 Tickborne Disease Workshop

Back in October 2010, the Institute of Medicine (IOM) held a workshop which was broadcast online live (and remains available at TV worldwide), Critical Needs and Gaps in Understanding: Prevention, Amelioration, and Resolution of Lyme and Other Tick-Borne Diseases: The Short-Term and Long-Term Outcomes.

The workshop participants were members of the Institute of Medicine, various researchers, doctors, and members of the Lyme disease patient advocacy community.

A preliminary summary report on the workshop was published by the IOM in April 2011. Now, an official final report has been published and is available on PubMed:

http://www.ncbi.nlm.nih.gov/pubmed/21977545

For a more detailed table of contents, try:

Excerpt

It was obvious to participants at the workshop that a significant impasse has developed in the world of Lyme disease. There are conflicts within and among the science; policy; politics; medicine; and professional, public, and patient views pertaining to the subject, which have created significant misunderstandings, strong emotions, mistrust, and a game of blaming others who are not aligned with one’s views. Lines in the sand have been drawn, sides have been taken, and frustration prevails. The “walk in the woods” process of conflict resolution or a similar process seems necessary for creating a new environment of trust and a better environment for more constructive dialogue to help focus research needs and achieve better outcomes. Such a process does not imply a compromise of the science but rather is needed to shift to a more positive and productive environment to optimize critical research and promote new collaborations.



I'd have to say this is a good report for those who are new Lyme disease and other tickborne illnesses to read in order to get an idea of what issues concern researchers and patients.

In terms of an action item plan and treatment to help patients, though, this report is lacking in either and what is sorely needed at this point in time.

0 News: New Molecular Test Could Detect Early Lyme Disease

The Guardian has written about a new molecular test using nanoparticles which was developed by Alessandra Luchini, of George Mason University, to initially detect cancers. The new test is being used in clinical trials to detect early Lyme disease - even if there is no rash present in the infected patient.

Excerpt that will be of interest to readers:
"Q: In years to come, is this something that could be available in hospitals? 
That's the hope we have. The first clinical trial is on the detection of Lyme disease. A fraction of patients get a skin rash but for those without the rash it is very difficult to diagnose. So with the particles we are able to capture the antigens that come from the spirochaete that is the causative agent of Lyme disease. If we see in the urine a piece of the bacteria of the spirochaete, we are sure that the patient has Lyme disease. We are gathering all the evidence and then we will need to go first for FDA approval before it is available in clinics. 
Q: How much earlier will you be able to detect Lyme disease? 
Lyme disease has a window of two to three weeks before seroconversion [production of antibodies in the host blood, indicating infection]. With our tests, we're able to detect it before seroconversion, because we're not looking for the antibodies, we just look for the spirochaete. I would say here, yes, by weeks, and earlier diagnosis would be beneficial for the prognosis."
Comment: One thing this does make me wonder about is how similar this test is to Temple Douglas' hydrogel nanoparticle test for early detection of Lyme disease. Maybe it's time to do a compare and contrast of patent application content?

0 An accident leads Yale scientists to tick-borne disease in Russia

The Connecticut Mirror has an article on the backstory behind discovering that Borrelia miyamotoi leads to infection in people:

An accident leads Yale scientists to tick-borne disease in Russia
http://www.ctmirror.org/story/13955/lyme-new-tick-borne-disease-yale

You've got to love this excerpt:
Fish's lab was studying Lyme disease transmission using ticks and mice, exposing ticks to mice that had been infected, and to others that had not. But the ticks exposed to uninfected mice appeared to be infected.

"I gave everybody in the lab hell for wasting a lot of time and resources and stuff, because they screwed up the experiment," said Fish, a professor of epidemiology at the Yale School of Public Health. "And they felt really bad and they couldn't understand how that happened."

In fact, the ticks had a different bacterial organism, not the one that causes Lyme, but a distant relation called Borrelia miyamotoi. It had been identified six years earlier in Japan, but no one knew if it caused illness in humans. Fish spent the better part of a decade trying to get funding to study it, with little success.

I guess I have these questions about this:

1) Has anything similar happened before in other experiments and we don't even know about it - this situation of having uninfected mice be infected by a different organism that is disease-causing?

2) Why wasn't there enough funding to study this? Who decides which projects get funded?

3) I noticed that Borrelia research at the NIH got a lot more funding in the past two years... What were the goals of the bulk of those projects?

I can probably find out the answer to #3 with some digging. The first two questions? Not as easy to answer.

0 News: In Wisconsin, Illnesses spread by ticks on rise

The Wisconsin Rapids Tribune has this article on tap today:

Illnesses spread by ticks on rise

Excerpts:
Consistent testing and an increase in deer ticks are driving up the number of tick-borne illnesses reported annually in Wisconsin, health officials said.

Statewide, cases of the bacteria infections anaplasmosis and ehrlichiosis -- both spread by deer ticks -- increased 70 percent from 2009 to 2010, when 546 cases were reported, according to state data.

"It's nice to be able to pick (anaplasmosis and ehrlichiosis) up, so a patient can be properly treated," said Diep Hoang Johnson, an epidemiologist for Wisconsin's Division of Public Health. "If lyme disease (tests) come back negative, they may not get treated and they may have one of these diseases."
and
"Marx said the increase in tick diseases other than lyme likely is because of more efficient testing and health care providers' improved efforts to report the illnesses."

Comments:

It's important to keep in mind that not every tick bite leads to a case of Lyme disease, and a negative Lyme disease test result does not necessarily mean the patient does not have Lyme disease (antibodies may not have been present at the time the test was taken) - nor does it indicate what other tickborne infections a person may have such as Ehrlichiosis or Babesiosis (as well as a few viruses which are spread by tick bites).

It's important for doctors and patients to familiarize themselves with the range of tickborne infections which are out there and be aware of the symptom spectrum for all them, as well as for doctors to take a detailed history from patients to see where they have traveled and resided to determine which tickborne diseases they are at greater risk of contracting. This provides a starting point for which coinfections to test for - but is by no means definitive as these diseases spread and even change in geographic location and density.

7 Tracking Lyme Disease in Dogs May Help Protect Humans: MedlinePlus

For the study,  a team led by Dr. Paul Mead, a CDC medical epidemiologist, used data from 46 states on human and canine Lyme disease prevalence.

Comparing the data, Mead's team found that when 1 percent or less of the dogs tested positive for Lyme disease, the risk of people becoming infected was low. However, when more than 5 percent of the dogs were infected, the risk to people was high.

Comment:

This is the kind of low cost surveillance data I think should have been collected all along - and let the vets do the data collection and reporting. I think it makes sense to use dogs to determine potential risk to humans because dogs roam around more and get in the tall grass - they go where the ticks are whereas people try to stay away from them. I consider a dog another potential piece of dragging white flannel flag.
