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.

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.

12 One Pill Of Doxycycline Is Not Enough To Prevent Early Lyme Disease


This paper is being passed around the Lyme disease patient community that has everyone's attention. It's about the most effective timing and the use of one 200 mg capsule of doxycycline as prophylaxis to prevent Lyme disease after a tick bite.

The bottom line from the authors of the study: One 200 mg capsule of doxycycline is totally ineffective in preventing Lyme disease if it is administered 48 hours after a tick bite.

And even if administered in less than 48 hours, it is no guarantee of successfully preventing infection.

The following commentary comes from Dr. Elizabeth Maloney:

Since 2001 the IDSA has been recommending preventive treatment of a single dose of doxycyline for tickbites under certain narrow conditions.  Piesman et al. have just published a new article concluding that if the treatment is given as little as 24 hours after the bite, only 47% of the mice were cured. Piesman also concludes that "Prophylactic treatment was totally ineffective when delivered ≥2days (48hrs) after tick removal." The IDSA recommends treating if:

  • Tick is estimated to have been attached for ≥36 hours (based upon how engorged the tick appears or the amount of time since outdoor exposure)
  • Antibiotic treatment can begin within 72 hours of tick removal 
"If the person meets ALL of the above criteria, the recommended dose of doxycycline is a single dose of 200 mg for adults and 4 mg/kg, up to a maximum dose of 200 mg, in children ≥ 8 years"

In 2004 Zeidner et al. noted that the "sustained release" doxy was curative, but regular doxy only 43% effective. [ Antimicrob Agents Chemother. 2004 Jul;48(7):2697-9. Sustained-release formulation of doxycycline hyclate for prophylaxis of tick bite infection in a murine model of Lyme borreliosis.]

In 2008 Dolan et al. reported on the success of 14 days of exposure to antibiotic bait formulations..

A doxycycline hyclate rodent bait formulation for prophylaxis and treatment of tick-transmitted Borrelia burgdorferi.Dolan MC, Zeidner NS, Gabitzsch E, Dietrich G, Borchert JN, Poché RM, Piesman J.

Abstract

The prophylactic and curative potential of doxycycline hyclate formulated in a rodent bait at concentrations of 250 and 500 mg/Kg was evaluated in a murine model of Lyme borreliosis. 
Both bait formulations prevented tick-transmitted Borrelia burgdorferi infection in 100% of C3H/HeJ mice (N = 16), as well as cured acute, established infection in mice (N = 8) exposed to bait for 14 days
Spirochete infection was cleared in 88.9% to 100% of infected nymphs feeding on mice fed 250 and 500 mg/Kg antibiotic bait formulations, respectively. These data provide evidence for exploring alternative techniques to prevent transmission of Lyme disease spirochetes.

In 2011 Wisconsin Journal of Medicine published a review detailing the failure of one-dose doxycycline prophylaxis and proposing an alternative, more effective treatment option. (Maloney, B. The management of Ixodes scapularis bites in the upper Midwest. WMJ. 2011 Apr;110(2):78-81; quiz 85.) 
The full text article is available at: http://www.wisconsinmedicalsociety.org/_WMS/publications/wmj/pdf/110/2/78.pdf

This month Peisman and Hoigaard note that "prophylactic treatment was totally ineffective when delivered ≥2days after tick removal." [2 days = 48 hrs]

Ticks Tick Borne Dis. 2012 Mar 13. [Epub ahead of print] Protective value of prophylactic antibiotic treatment of tick bite for Lyme disease prevention: An animal model. Piesman J, Hojgaard A.

Abstract

Clinical studies have demonstrated that prophylactic antibiotic treatment of tick bites by Ixodes scapularis in Lyme disease hyperendemic regions in the northeastern United States can be effective in preventing infection with Borrelia burgdorferi sensu stricto, the Lyme disease spirochete. 
A large clinical trial in Westchester County, NY (USA), demonstrated that treatment of tick bite with 200mg of oral doxycycline was 87% effective in preventing Lyme disease in tick-bite victims (Nadelman, R.B., Nowakowski, J., Fish, D., Falco, R.C., Freeman, K., McKenna, D., Welch, P., Marcus, R., AgĂșero-Rosenfeld, M.E., Dennis, D.T., Wormser, G.P., 2001. Prophylaxis with single-dose doxycycline for the prevention of Lyme disease after an Ixodes scapularis tick bite. N. Engl. J. Med. 345, 79-84.). 
Although this excellent clinical trial provided much needed information, the authors enrolled subjects if the tick bite occurred within 3days of their clinical visit, but did not analyze the data based on the exact time between tick removal and delivery of prophylaxis. An animal model allows for controlled experiments designed to determine the point in time after tick bite when delivery of oral antibiotics would be too late to prevent infection with B. burgdorferi
Accordingly, we developed a tick-bite prophylaxis model in mice that gave a level of prophylactic protection similar to what had been observed in clinical trials and then varied the time post tick bite of antibiotic delivery. We found that two treatments of doxycycline delivered by oral gavage to mice on the day of removal of a single potentially infectious nymphal I. scapularis protected 74% of test mice compared to controls. When treatment was delayed until 24h after tick removal, only 47% of mice were protected; prophylactic treatment was totally ineffective when delivered ≥2days after tick removal. 
Although the dynamics of antibiotic treatment in mice may differ from humans, and translation of animal studies to patient management must be approached with caution, we believe our results emphasize the point that antibiotic prophylactic treatment of tick bite to prevent Lyme disease is more likely to be efficacious if delivered promptly after potentially infectious ticks are removed from patients.


There is only a very narrow window for prophylactic treatment to be effective post tick removal.

In my opinion, a study like this one should have been done long ago. How many studies were used to make the original determination that one 200 mg capsule of doxycycline would be an appropriate method of prophylaxis against Lyme disease? 

 And the obnoxious thing is, I was given this treatment! I had a tick bite, I had an EM rash, I was concerned about Lyme disease - and the first doctor I saw said there was no Lyme disease in the area in which I had been bitten, but I was given the one pill of doxycycline as some sort of consolation prize... The implication from the doctor being that the bite was most likely nothing to worry about and the pill being given to me to placate me.

Well, this prophylaxis apparently was not very prophylactic, now, was it?

I am pretty sure I saw the doctor 3-4 days after the tick bite, when I was given the prescription paper to fill it for one capsule of doxycycline.

This prophylactic approach never made sense to me from the day I first learned about the one pill preventative.

Since my failed experience of preventing Lyme disease, I've learned that different strains/subspecies of Borrelia burgdorferi disseminate at different rates, with different bacterial loads from different bites. If infection is present - one pill is hardly going to stop it. And if a coinfection is present, it may have an impact on the immune system which is hard to predict and may alter how effective an antibiotic is on the big picture.

One of the things I've learned in the past couple of weeks of doing research on Russian web sites about how patients are affected by Lyme disease and what treatments are given to patients there is that there is more of a sense of urgency of treating Lyme disease early and also aggressively. This is not to say that the Russian approach of managing Lyme disease is the best overall - they too have a problem with chronic Lyme disease - and so far as I can see, have not found the perfect treatment for it.

But if what I read so far is to be taken into account, then their approach has been to treat Lyme disease as early as possible and have doctors remove ticks as soon as one has a tick bite because research has shown the earlier a tick is removed properly, the greater the risk is reduced in transmitting infection.

In addition to encouraging immediate professional tick removal and early treatment during the acute stage, a number of medical clinics and web sites recommend a few days of prophylactic doxycycline - rather than one pill.

I am still looking for Russian research papers which support this approach - so perhaps take this information with some caution. But here are two sites which mention this approach which would appear to be legitimate resources:

First site, the equivalent of city council pages for  Lipetsk:

ORDER ON Surveillance FOR Ixodes tick-borne borreliosis -- Excerpt:
"Carry an emergency antibiotic prophylaxis should be based only on display in the pathogen attached ticks. In the case of the pathogen in the vector and not later than 3 days. of tick suction in patients prescribed a course of doxycycline at 0.1 x 1 time per day for 5 days (children under 8 years of this antibiotic is not indicated).

Later on the third day from the time course of doxycycline tick suction extended to 10 days. Other antibiotics, which can be used for preventive treatment, drugs are prolonged penicillin: bicillin 3 or retapen (ekstentsillin) at a dose of 2.4 million units. intramuscularly once after a skin test on the individual tolerance of antibiotic.

Has a high efficiency combination drug amoxicillin with clavulanic acid (amoxiclav) to 0.375 g, 3 times a day, 5 days.
When carrying out emergency prophylaxis following should be considered (Appendix 9):
- Epidemiological history - a fact suction to the skin of ticks;
- Results of microbiological studies, parazitologo - detection of Borrelia in the attached ticks by dark-field microscopy or PCR;
- Start of antibiotic timing - as soon as possible after the suction (after the 5th day of tick suction inappropriate use of approved schemes), early prevention of borreliosis - a day after the suction of an infected tick Borrelia - can be recommended only when a negative result of the study attached ticks in the ELISA CEA antigen;
- A good individual tolerability of recommended antibiotics;
- Carrying antibiotics under medical supervision;
- Follow-up visit within 1 - 3 months after the course of antibiotic prophylaxis in SDS"

And then here's another, for Nizhny Novgorod State Medical University, which has been around since 1920:
"At the present time in Nizhny Novgorod and the region is high infection of ticks with borreliae, there are also ticks infected with tick-borne encephalitis. You must know the pattern of action in the case of tick suction.

First, you must remove the tick, while maintaining its viability. You can do it yourself or by contacting the trauma center in your area.

Remote mite be sent to study in Nizhny Novgorod Research Institute of Epidemiology and Microbiology. Academician I. Blokhina (St. Georgia 44, 433-76-55, 434-17-71, www.micro.nnov.ru). Within a day you will get the result of the study.

If the tick was infected with Borrelia, to conduct preventive 10-day course of doxycycline (T. Doxiciclini 0,1 to 1 m, 2 times a day).

If the tick was infected with tick-borne encephalitis, showed immunoglobulin, but the free drug can qualify only if after the bite was not more than 4 days."
The above, in Russian:

So far as I can see, the use of a longer period of prophylactic treatment is advised - but the public health department also makes an effort to test the tick you have had on you for the presence of bacteria and viruses. The turn around time is less than 24 hours for results.

The only problem with this approach is that if you get a tick bite which is not obvious and it is not found right away, the odds of getting Lyme disease and/or Tick-borne encephalitis (TBE) are greater. Treatment may come too late to help a patient - particularly in the case of  TBE, where immunoglobulin for TBE and antiviral medication will only help if administered in under 72-96 hours after the tick bite.

There are three reasons I suspect Russia is more aggressive in its approach:

1) While the odds of getting TBE are lower than the odds of getting Lyme Borreliosis, TBE has a much higher risk of leading to acute severe illness and death. The older one is when they are infected with TBE, the higher the odds are of serious complications and fatality.

2) The most common strain of Borrelia people are infected with in Tomsk - a highly endemic area of Russia - is B. garinii, and a specific type of B. garinii quickly disseminates to the CNS more quickly than other strains. To prevent neuroborreliosis and widespread dissemination to other organs, a longer prophylactic course is needed as soon as possible.

3) Polymicrobial or coinfection is not uncommon. It is possible to be infected with both Lyme Borrelia and TBE, or more than one strain of Borrelia burgdorferi, and perhaps throw in Anaplasmosis in there as well. One has to be very careful of how to treat such cases - if TBE is present, it must be treated first since it moves fast, is more dangerous, and early antibiotic use is contraindicated in its presence.

All this said, I do wonder how it was determined that prophylaxis should be 5-10 days, based on circumstances surrounding the bite. This is a much longer course than the IDSA has suggested.

And frankly, this sort of treatment is what I wish I had if it would have prevented the situation in which I now find myself.

Addendum [April 29, 2012]: I wanted to add the following passage from a paper from The Canadian Entomologist:
"Studies of the transmission dynamics of B. burgdorferi in I. scapularis indicate that the risk of transmission of strain B31 by a single bite from an infected tick is about 2% and that the risk increases with the length of time that the tick is attached (Hojgaard et al. 2008). 
When a tick first attaches, spirochetes are still found in the midgut and are producing outer-surface protein A (OspA), which helps spirochetes adhere to a midgut protein, TROPSA. When feeding begins, the spirochetes are exposed to warm mammalian blood and lowered pH, and OspA is downregulated while OspC is upregulated. Spirochetes then migrate from the midgut to the salivary gland and transmission to the vertebrate host can be achieved (e.g., Hojgaard et al. 2008). This delay in transmission explains why transmission is reduced when ticks are removed within 24 h of attachment (Hojgaard et al. 2008). 
In Europe, transmission of B. burgdorferi s.s. and B. afzelii by I. ricinus occurs in less than 24 h, but the risk of transmission still increases over time (Kahl et al. 1998; Crippa et al. 2002). In a further complication of the host—tick—pathogen interaction, B. burgdorferi s.l. is able to increase expression of an Ixodes salivary protein, Salp 15, to protect against complement-mediated killing of Borrelia by the host's innate immune system (Ramamoorthi et al. 2005). This protective effect was greater when the vector was I. ricinus rather than I. scapularis (Schuijt et al. 2008). The early expression of ospC appears to be essential for B. burgdorferi to escape innate immunity and disseminate in the host (Gilbert et al. 2007), and yet persistent infection of the host is only possible when ospC is downregulated after infection because acquired antibodies to OspC allow the spirochetes to be cleared (Tilly et al. 2007). Current understanding of the interactions of tick saliva and B. burgdorferi is discussed in Anderson and Valenzuela (2007)."

The above passage is important to note because it outlines the fact that the rate of transmission of spirochetes from the tick to its host varies based on a number of factors including Borrelia strain, the type of tick involved, Salp15 production levels, expression of ospC, and length of time the tick has been attached.

Based on this research, it is clear additional research is needed to determine if strains of Borrelia burgdorferi other than B31 in Ixodes scapularis and Ixodes pacificus would have differing transmission times tested under the factors mentioned. The same sort of studies would be beneficial for Europeans on Ixodes ricinus and other European Ixodes ticks.

2 Brief remarks on an older post about forum rules

I am somewhat puzzled that of all that I have posted here thus far, a post on forum posting rules I do not understand is one that continues to get a fair number of hits.

Why do people think this post is so interesting? I think Kary Mullis' Altermune research is way more interesting than that. To each his own, I guess.

Anyway... I've revisited this issue on a forum thread recently, and those who responded seemed to have not read what I wrote in the first place, and responded that I should know why LLMDs need to have their identities protected and know about the film, Under Our Skin.

I do know about why, and I have seen the film. Twice. I had a copy of the disk, which is now in the hands of a therapist who counsels people with disabilities and chronic illness.

Since my point seems to have gotten lost somehow, I will explain what I think about forum posting rules about LLMDs here once more in more abbreviated terms:
It seems to me that it makes more sense to use the term "My LLMD" or "My MD" when posting to a forum about someone giving me medical treatment, and more sense to use the term "An LLMD" or "An MD" when posting about a medical doctor who is not mine. 
Given that there is a small number of doctors who are LLMDs, I do not think that using an initial alone or an initial and a state is adequate privacy - if your goal is privacy. Those who are familiar with doctors who have already been in the spotlight may figure it out, and those who are patients may try to figure out which doctor is being discussed. 
Other mailing lists have used the above approach with great success and it removes confusion over what posters should do.

My rules for my own blog are somewhat modified to allow for mentions in the media and publications.

Alrighty then.
