IGeneX introduces new tests for Lyme disease & tick-borne relapsing fever
Press release from IGeneX, October 16, 2017

IGeneX Inc., a CLIA and New York-approved Reference Laboratory, specializing in testing for tick-borne diseases, is pleased to announce the launch of three new tests that are more inclusive and specific for aiding in diagnosis of Borreliosis (Lyme Disease and Tick-Borne Relapsing Fever, Borreliosis).

— Lyme ImmunoBlotIgM and IgG

— Lyme ImmunoBlotIgM and IgGTBRF ImmunoBlot IgM and IgG

— Lyme ImmunoBlotIgM and IgGTBRF ImmunoBlot IgM and IgGLyme IGX Spot

— Lyme ImmunoBlotIgM and IgGTBRF ImmunoBlot IgM and IgGLyme IGX Spot

https://www.igenex.com/testing/  Go here for testing specifics

Borreliosis is caused by two groups of Borrelia, B. burgdorferi group and the Tick-Borne Relapsing Fever (TBRF) Borrelia group. Until recently, it was believed that B. burgdorferi group was the only group that caused Lyme-like symptoms. However, we now know that TBRF Borrelia also causes Lyme-like symptoms. Therefore, IGeneX developed two sets of Immunoblots, Lyme ImmunoBlot IgM and IgG and TBRF ImmunoBlot IgM and IgG.

Many patients with Lyme-like symptoms are misdiagnosed because: (1) The current serological tests cannot detect antibodies to all the different strains of B. burgdorferi (2) For TBRF Borrelia, only two serological tests, an IFA test for B. hermsii and a serological test that detects only B. miyamotoi GlpQ protein, are available. In addition, with the increase in tick populations, Borreliosis is on the rise. Thus, there is an urgent need for better diagnostic tests for Borrelisosi.

Because symptoms of Lyme and Tick-Borne Relapsing Fever are often similar, a more comprehensive battery of tests is critical for proper diagnosis.

“IGeneX’s new Lyme ImmunoBlot and the TBRF ImmunoBlot tests are the first, most inclusive and specific serologic tests for Lyme disease and TBRF,” said Dr. Jyotsna Shah, President and CEO of IGeneX. “These tests, when combined with Lyme IgX spot and PCR, cover the full spectrum of the disease.”

Lyme ImmunoBlots IgM and IgG

Although IGeneX Lyme Western blot prepared from Borrelia burgdorferi strains B31 and 297 is one of the most sensitive tests, it does not detect antibodies to all the B. burgdorferi sensu lato antigens. To develop all-inclusive Western blots would be very expensive and impractical. Therefore, IGeneX has developed a Lyme ImmunoBlot that is very specific and inclusive of most species of B. burgdorferi sensu lato for clinical use with the following advantages over a Western blot:

The specificity of the ImmunoBlot is 98.0% for IgM and 98.7% for IgG. This is higher than the traditional Western Blot.
The 31kDa Epitope confirmation test will not be required on patient samples tested by Lyme ImmunoBlots.
The sensitivity of the Lyme Immunoblot is 90.9% with well-defined samples.
The ImmunoBlot has better sensitivity compared to the current Western Blot, because it t is designed to detect antibodies to major burgdorferi sensu lato specific antigens from North America and European strains as listed below:
B. burgdorferi B31
B. burgdorferi 297
B. californiensis
B. mayonii
B. afzelii
B. garinii
B. spielmanii
B. valaisiana

TBRF ImmunoBlots IgM and IgG

The TBRF ImmunoBlot is designed to detect antibodies to specific antigens of TBRF Borrelia in human serum. It detects antibodies to B. hermsii, B. miyamotoi, B. turicatae and B. coriaceae. Based on in-house studies these blots detect antibodies to North American, European and Australian strains of TBRF Borrelia in patient serum samples. The specificity of the TBRF ImmunoBlot is 94% and 98% for IgM and IgG respectively.

Lyme IGX Spot

The Lyme IGXSpot is an Enzyme-Linked ImmunoSpot (ELISPOT) assay that detects human T cells reactive to B. burgdorferi-specific antigens in vitro. ELISPOT is a widely used method for detecting and monitoring cellular immune responses to specific antigens.

The Lyme IGX Spot test:

Detects specific T-cell responses soon after B. burgdorferi infection, when antibodies to the organisms are not detectable or late in the disease, when the levels of antibodies are very low.
When combined with Lyme ImmunoBlot tests, information on the full spectrum of patient’s immune response to infection and stage of disease is obtained.
Is especially useful for seronegative patients.

 

Dr. Miller – A New Perspective on Lyme Disease

NightSide – A New Perspective on Lyme Disease

BOSTON (CBS) – Dr. Alfred Miller is a Mayo Clinic trained physician with four decades of experience running a private practice. He believes that there may be a connection between Lyme Disease, ALS, and MS. Tonight, he joins Dan in studio (all the way from Texas!) to talk about his research and take some listener calls. Tune in to hear his perspective and find out about some of the cases he’s seen.

**Comment**

Great interview.  Dr. Miller points out the insensitivity of current CDC 2-tier testing, the fact many patients with autoimmune diseases have undiagnosed Lyme, that other insects carry borrelia, the causative agent of LD, and the importance of going off immunosuppressive drugs for at least a month, taking at least 21 days of doxycycline to evoke an immune response, and then taking a Lyme test. (Please only work with a Lyme literate doctor.  Contact your local support group for more doctor information)

A word of caution:  while some LLMD’s use the CD-57, others do not.

https://heallyme.wordpress.com/2009/01/28/understanding-the-cd-57-test/   It is important to remember that the CD57 result is just a number; far more important is the patient’s clinical status. An old professor of mine used to say, “treat the patient, not the lab test!” There is still much we do not know about the CD57 marker and what other factors may lower or raise it.

Dr. Marty Ross rarely uses the CD-57 – here’s why:  http://www.treatlyme.net/treat-lyme-book/cd-57-test-rarely/  I rarely recommend a CD-57 test because in most situations it is not useful and has no real predictive or helpful value in charting the course of a person’s care. See why in this Lyme Byte from our webinar Conversations with Marty Ross MD on 09/10/13.  The CD-57 is a type of a natural killer white blood cell that often is less than normal in chronic Lyme disease. Some other Lyme literate medical doctors recommend it as a way to see if a person has Lyme and to follow the course of his/her treatment.

Dr. Miller points out that doxycycline only kills the spirocheteal form and the L-form of Lyme and does not kill the cyst form so when people are given doxy only, they are not eradicating the organism.  Most LLMD’s use a combination of antibiotics.  Only uninformed practitioners use doxy only.

He also recommends the IgeneX test.  https://madisonarealymesupportgroup.com/2016/12/07/igenex-presentation/

A Couple of points:  Some patients NEVER test positive on any Lyme test and/or coinfection test for that matter.  In fact a highly reputable LLMD in WI states the very sickest patients often never test positive.  It truly helps to print and fill out Dr. Horowitz’s questionnaire.  If you have a preponderance of symptoms, chances are high you have Lyme:  https://madisonarealymesupportgroup.files.wordpress.com/2016/01/symptomlist.pdf

Also, consider these coinfection checklists:

Please contact your local support group.  Seriously, these people are the boots on the ground and are familiar with the lay of the land in your state.  They know the good treating physicians, their costs, their regimens, and other helpful information.  You do not have to go this alone.

Droplet Digital PCR Shows 60% Bb Infection Rate in Ticks and Over 50,000 Spirochetes Per Adult Tick

https://www.cambridge.org/core/journals/parasitology/article/validation-of-droplet-digital-pcr-for-the-detection-and-absolute-quantification-of-borrelia-dna-in-ixodes-scapularis-ticks/A47CEB12C767C573BEB7AD8BD8E3A252

Validation of droplet digital PCR for the detection and absolute quantification of Borrelia DNA in Ixodes scapularis ticks

Summary

We evaluated the QX200 Droplet Digital PCR (ddPCR™, Bio-Rad) system and protocols for the detection of the tick-borne pathogens Borrelia burgdorferi and Borrelia miyamotoi in Ixodes scapularis nymphs and adults collected from North Truro, Massachusetts. Preliminary screening by nested PCR determined positive infection levels of 60% for B. burgdorferi in these ticks. To investigate the utility of ddPCR as a screening tool and to calculate the absolute number of bacterial genome copies in an infected tick, we adapted previously reported TaqMan®-based qPCR assays for ddPCR. ddPCR proved to be a reliable means for detection and absolute quantification of control bacterial DNA with precision as low as ten spirochetes in an individual sample. Application of this method revealed the average carriage level of B. burgdorferi in infected I. scapularis nymphs to be 2291 spirochetes per nymph (range: 230–5268 spirochetes) and 51,179 spirochetes on average in infected adults (range: 5647–115,797). No ticks naturally infected with B. miyamotoi were detected. The ddPCR protocols were at least as sensitive to conventional qPCR assays but required fewer overall reactions and are potentially less subject to inhibition. Moreover, the approach can provide insight on carriage levels of parasites within vectors.

 

**Comment**

While this is a great start, there are many other pathogens to be concerned with besides Borrelia burgdorferi (Bb), the agent of Lyme Disease:  https://madisonarealymesupportgroup.com/2017/07/01/one-tick-bite-could-put-you-at-risk-for-at-least-6-different-diseases/, and there are many more besides the six mentioned in this article.  Bartonella has not been proven conclusively to be transmitted by ticks, but it is highly likely.  It is also a frequent coinfection and can be spread by:

Arthropod vectors including fleas and flea feces, biting flies such as sand flies and horn flies, the human body louse, mosquitoes, and ticks; through bites and scratches of reservoir hosts; and potentially from needles and syringes in the drug addicted. Needle stick transmission to veterinarians has been reported. There is documentation that cats have received it through blood transfusion. 3.2% of blood donors in Brazil were found to carry Bartonella in their blood. Bartonella DNA has been found in dust mites. Those with arthropod exposure have an increased risk, as well as those working and living with pets that have arthropod exposure. 28% of veterinarians tested positively for Bartonella compared with 0% of controls. About half of all cats may be infected with Bartonella – as high as 80% in feral cats and near 40% of domestic cats. In various studies dogs have close to a 50% rate as well. Evidence now suggests it may be transmitted congenitally from mother to child – potentially leading to birth defects.  https://madisonarealymesupportgroup.com/2016/01/03/bartonella-treatment/

There is much work yet to be done.

 

 

 

 

 

Premature Infants Develop Babesia Via Blood Transfusion

https://insights.ovid.com/crossref?an=00006454-900000000-96882

A Cluster of Cases of Babesia Microti Among Neonates Traced to a Single Unit of Donor Blood

Abstract

Three premature infants in one neonatal intensive care unit (NICU) developed transfusion-transmitted babesiosis. Two of the infants developed high-grade parasitemia. All three affected infants were treated and cured with azithromycin and atovaquone. No infant required exchange transfusion. Clinicians should be cognizant that babesiosis may be acquired via blood transfusion.

**Comment**

Babesia is finally getting the press it deserves.  Lately there has been much on transmission by transfusion as well as deaths in patients without spleens.

https://madisonarealymesupportgroup.com/2017/08/08/transfusion-transmitted-babesiosis-in-nonendemic-areas/   “Asymptomatic individuals with Babesia infection are able to donate blood in the United States because of the lack of specific blood donation testing. Blood products collected in Babesia-endemic areas are distributed nationally; thus, clinicians in nonendemic states may fail to include babesiosis in the differential diagnosis of a patient who had a recent transfusion history and a fever of unknown origin.”  

https://madisonarealymesupportgroup.com/2017/08/30/babesia-spread-to-newborn/ Babesia spread congenitally

https://madisonarealymesupportgroup.com/2017/09/25/man-dies-of-babesia/  Death in patient without spleen

https://madisonarealymesupportgroup.com/2016/12/15/blood-screening-for-babesia/   Blood-donation screening for antibodies to and DNA from B. microti was associated with a decrease in the risk of transfusion-transmitted babesiosis.

https://madisonarealymesupportgroup.com/2016/01/16/babesia-treatment/  Dr. Horowitz, a nationally recognized LLMD, states Babesia is one of the most tenacious coinfections he sees in his patients and that treatment often takes 9 months to a year, particularly with those also infected with Lyme disease (borrelia).  Treatment options in this link.  

http://www.nejm.org/doi/full/10.1056/NEJM199807163390304  When left untreated, silent babesial infection may persist for months or even years. Although treatment with clindamycin and quinine reduces the duration of parasitemia, infection may still persist and recrudesce and side effects are common. Improved treatments are needed.

Dr. Krause published in the New England Journal of Medicine that when a patient has Lyme and Babesia, Lyme is found three-times more frequently in the blood, proving Babesia suppresses the immune system.  http://danielcameronmd.com/babesia-and-lyme-its-worse-than-you-think/

https://madisonarealymesupportgroup.com/2017/06/28/concurrent-babesiosis-and-lyme-in-patient/   Dr. Horowitz warns that due to this immune suppression, patients with Rheumatoid Arthritis or Lupus and are on immunosuppressant drugs, if they have Babesia, could get much worse. The strain, B. divergens, causes a higher mortality rate and more severe symptoms, and if left untreated, this strain can develop into shock-like symptoms with pulmonary edema and renal failure.

 

Speaking of Fake Science: Fifty-Seven Million Anti-Trust Lawsuit Against CDC Lyme Tests

Unprecedented claim against the CDC over Lyme tests

Written by
Unprecedented claim against the CDC over Lyme tests

In the USA an unprecedented anti-trust law suit of $57 million is being prepared against the CDC. They are accused of deliberately suppressing the use of an accurate DNA direct diagnostics for Lyme disease. You can read about the aim and potential impact of this lawsuit in this article.

 

In the current situation, even in an endemic area like Connecticut, the first doctor a Lyme patient sees is an emergency room physician” – Dr. Sin Hang Lee at the 2017 ILADS conference in Paris, Europe

Introduction

Lyme disease belongs in the same health threat category as AIDS and cancer, while it is far more prevalent than Zika. With over 300,000 new cases annually in the USA alone, the incidence of Lyme is now six times the AIDS epidemic and it is twice as prevalent as breast cancer.  

Early detection and treatment of Lyme disease is of utmost importance, but it is well known that typical antibodies are not detectable for 4-6 weeks after infection. The lack of diagnostic tests for early Lyme disease has caused untold pain and suffering worldwide as delayed diagnosis and treatment often leads to “chronic Lyme disease” or “Post Treatment Lyme Disease Syndrome”. The current situation has been framed as a human rights abuse on a global scale. 

For decades, the reliability of Lyme diagnostics has been subject to critique. A few doses of doxycycline prescribed will almost guarantee a negative two tier serology test. Historically an indirect way of proving the causative pathogen for Lyme Borreliose (LB) has been used, since direct diagnostics such as microscopy, PCR and DNA testing were lacking. The current two-tier serological test system (with ELISA and Western Blot) seem to have many false-negative results. A recent meta-analysis showed that the number of false-negatives are over 500 times higher than with the two-tier testing on HIV.

Recently Dr. Becker, director of the Association of Public Health Laboratories, publicly admitted that “Lyme disease presently cannot be diagnosed based solely on a laboratory test because the tests still aren’t good enough.

Fortunately, medical technology has evolved during the last three decades. DNA sequencing produces no false-positives and can measure the presence of the Borrelia beyond a reasonable doubt. This method works even with low bacterial density in the blood, provided that specific precautions are taken.

According to Dr. Lee, director of Milford Molecular Diagnostics, Connecticut, the CDC should launch a national competitive proficiency test program. The goal of this program should be to select the laboratory methods which can detect low density of borrelial spirochetes in whole blood samples for patient management. He had tried to work with them to achieve that goal.

Attempt at cooperation

On the Change.org petition of Carl Tuttle, the history of this effort is well described: Dr. Lee and David Shearer originally contacted the CDC for collaboration. Marty Schriefer of the CDC agreed to assist. Schriefer sent archived sera from the CDC’s Lyme disease repository for testing using Dr. Lee’s lab developed PCR/sequencing test in a CLIA-certified laboratory.

In 2013 the CDC provided 52 blind-coded archived serum samples – including 12 from post treatment and 20 pretreatment clinically suspect Lyme disease patients – and 20 negative serum samples to Milford Molecular Diagnostics.

These samples were provided for the purpose of evaluating the accuracy of a new diagnostic test for Lyme disease by Nested PCR and DNA Sequencing.

Dr. Lee’s technology uncovered a novel Borrelia in one of the serum samples tied to a patient in the Hudson Valley, who had been previously treated for neurologic Lyme disease (DNA sequence deposited in GenBank under accession number KM052618). Dr. Lee also found Borrelia miyamotoi in one of the CDC’s Lyme disease serum samples.

As a result, Dr. Lee informed the CDC that the nested PCR/16S rRNA sequence analysis has been shown to be an effective testing platform for accurate diagnosis of Lyme borreliosis at the spirochetemic stages of the infection, even for some chronic Lyme disease patients. 

This is a serious problem and clearly identifies that there is no accountability at the CDC. It would appear that the serum repository for Lyme disease has many problems and that samples may also be wrongly coded. 

Using these samples to determine the validity of future test kits is highly questionable, whereas nested PCR and Sequencing through Milford Molecular Diagnostics can detect different strains of bacteria causing Lyme borreliosis with as few as 25 bacteria per mL of blood.

According to Dr. Lee, at a Telecom conference on Friday October 25, 2013 among Dr. Schriefer and Dr. Molins of the CDC, Dr. Shearer and Dr. Lee, the CDC agreed to organize a national study program to further evaluate and promote new diagnostic tests and encouraged researchers to develop direct test methods, including the 16S rRNA sequence analysis technology.

Based on this agreement a research protocol was initially drafted by Dr. Lee and Dr. Shearer, and submitted on December 19, 2013 to Dr. Molins and Dr. Schriefer for their review. Dr. Schriefer indeed had reviewed, commented and edited the protocol and returned the edited copy to Dr. Shearer for revision on December 26, 2013. Dr. Lee and Dr. Shearer returned the protocol revised according to Dr. Schriefer’s recommendations in January 2014 to be finalized and implemented.

The CDC commitment to the national study abruptly stopped with no reasons given. However, it appears the CDC is focusing on developing their own newly patented test rather than supporting a group of innovators that compete with the CDC patents.

But not only the project itself was ended. When Dr. Lee published his findings, Detection of Borreliae in Archived Sera from Patients with Clinically Suspect Lyme Disease, all communication with the CDC suddenly stopped. In the meantime, CDC developed a novel test based on metabolite detection.

As with serology, such a test is an indirect test, and does not directly detect the bacterium. In an open PubMed comment Dr. Lee characterized the metabolite measurement as “an unproven technology” which “has deviated from the classic teachings of diagnostic microbiology”.

The current law suit

The current legal case is unprecedented and complex. Due to “sovereign anti-trust immunity” to protect the US government from claims by its own people, the current claim against the CDC is a long and difficult process. According to the Federal Tort Claims Act, one can only sue the government or its employees for damage by submitting an SF-95 form with supportive documents for money compensation only.

Through the law firm of Moore Leonhardt & Associates LLC, Dr. Sin Lee of Milford Molecular Diagnostics has now submitted the SF-95 form with documents to support the $57 million damage claimed, based on a complaint of 16 pages and a file of Exhibits of 376 pages. This amount of $57 million is 10% of the annual Lyme testing dollar volume charged to the insurance companies by 7 large commercial laboratories in the United States.

The CDC is accused of violation of the antitrust law in suppressing a direct testing method to diagnose an emerging infectious disease (Lyme borreliosis), which the CDC itself has called the ‘fastest growing vector borne disease in the USA’.

One of the purposes of the current lawsuit is to make the Exhibits public, so that Lyme disease patients can ask their lawyer to use the Exhibits to file their own SF-95 form for damages due to delayed diagnosis.

If he wins his case, Dr. Lee intends to donate the money to a non-profit organization to set up nested PCR/16S rRNA sequence diagnostic laboratories in hospitals located in Lyme disease-endemic areas so that all Lyme patients can be diagnosed early within a few days of first symptomatic presentation and receive timely and proper treatment. 

These diagnostic centers will further improve the sensitivity of the PCR procedure so that a very low density of spirochetemia in chronic Lyme patients can be diagnosed for further appropriate management. He also hopes that the insurance companies will pay for these tests, which should cost no more than the WB tests.

How to set up proper Lyme diagnostics?

In a letter to Jane Philpott, Federal Minister of Health of Canada, hand-delivered on August 22 2017, Dr. Lee explains how easy and cost-effective it would be to set up proper nationwide Lyme testing:

  1. Establish one National Lyme Disease Diagnostic Laboratory with Sanger sequencing facilities. The equipment costs less than US $300,000. This Lab also serves as an educational and training center.
  2. Set up 10 local PCR laboratories attached to the existent laboratories of regional hospitals located in Lyme disease endemic areas. Each of these laboratories will be equipped with one high speed micro-centrifuge to collect circulating spirochetes from platelet-rich plasma samples from suspected Lyme disease patients. The additional thermocycler, micro-centrifuge and PCR setup may cost about $15,000 at each site.
  3. The DNA extracted from the pellet of the platelet-rich plasma will be amplified with comprehensive genus-specific borrelial nested PCR primers for 16S rRNA gene detection at the local laboratories.
  4. The PCR results should be available within 2-3 working days after the patient’s visit. The PCR positive results are very accurate in the diagnosis of Lyme borreliosis for initiating timely treatment.
  5. The positive PCR amplicons will be sent to the national Lyme diagnostic laboratory for Sanger sequencing final validation.

In a reply to Dr. Becker, Dr. Lee also wrote that “the excuses commonly used to suppress using and development of direct DNA tests for the diagnosis of Lyme borreliosis include potential sample cross contamination, false identification of target DNA and lack of sensitivity. However, these are technical issues which can be overcome by good laboratory practices.”

He made this proposal for a national proficiency test project in the USA to advance the diagnostics in this area, which you can find here. However, he does not believe that anything will happen in the USA due to the financial stakes in keeping the current situation as it is.

A precedent?

Since Dr. Lee is not a Lyme patient nor a victim of delayed diagnosis himself, he cannot claim damage as a patient. So he can only sue the government for damage to his business (in terms of dollars).

Both American Lyme patients and Medical Doctors are also able to use a SF-95 claims form, within two years since the date when CDC’s suppression of using an available 16S rRNA sequence analysis as a reliable direct test method for diagnosis of early Lyme borreliosis was made public, namely on July 20, 2017. It could achieve two things: individual compensation and collective financial pressure to show that the CDC suppression of direct testing has led to delayed diagnosis of Lyme disease or missed diagnosis of Lyme disease, and the resulting devastating effects on public health, loss of income, expenses, general quality of life and a gross violation of basic human rights.

It is however not easy to sue the CDC, the European version ECDC or the Health Department of your national government, such as the RIVM in the Netherlands. You could be facing a long battle as – due to sovereign immunity protection – you may not be able to sue government employees. In the USA the exception is under Federal Tort Claims Act via the SF-95 form. You may need a lawyer to do this properly. 

One cannot file a case in court until the Complaint is cleared with the federal agency (CDC) and the OIG. This means waiting for six months, if they do not rule. This is called “exhausting administrative remedies”. This legal option has been used so little by either patients or doctors that there are hardly any lawyers who are specialised in filing these claims.

As history of social revolution has shown over and over again, all effective action once started with a single try. As Dr. Lee puts it: We have tried everything: reasoning, petitions, complaining, pleading. It’s time to change course. However, I am a lone wolf with one meagre voice. If a thousand patients are filing 1000 SF-forms, each demanding $1 million damage due to suppression of early diagnostics, the judge may think differently. Even if I lose the case and the patients win $100,000 per case, the CDC would have to change its Lyme policy. Someone has to try and we are given the opportunity now.”

The Future of Lyme Disease – Final Contagion Live Segment

 Contagion Live  Sept. 7, 2017  Approx. 10:30

Peter L. Salgo, MD: What are we looking for going forward 10 years from now? What is the future of Lyme disease management, whether or not it be testing improvements?

Robert C. Bransfield, MD, DLFAPA: I would think, eventually, you see a trend towards more DNA-based testing platforms that may evolve. I think, eventually, there would be better testing that would help. The question of vaccines, that has been something that people have been struggling with for a long time. One interesting thing is vaccines against ticks themselves, because there have been a lot of problems with the vaccines so far. I think that of those different things that are being considered, that’s probably the best option. So, it has been very hard to develop a vaccine. Just like a vaccine against the common cold. It may not be possible. I would love to see it happen.

Samuel Shor, MD, FACP: One of the major problems is, even if you have a good vaccine for Borrelia, what do you do about the co-infections? And more and more ticks are co-infected.

Leonard Sigal, MD: That’s why, going back to your anti-tick idea, there’s a wisdom commonly shared: the more erythema, the more redness and inflammation you develop at a tick bite site, the less likely you are to actually get infection.

Samuel Shor, MD, FACP: More robust immune response.

Leonard Sigal, MD: And so, that goes back to your comment. If you could come up with a tick saliva vaccine, not only would you cover Borrelia burgdorferi, but you’d also cover coinfections as well.

Robert C. Bransfield, MD, DLFAPA: And I also think there’s a trend towards looking in the microbiome— the tick microbiome, the human microbiome—and that’s part of disease. It’s not like you can ever just get rid of all infection in the body. It’s the microbiome that’s within us, and that’s, I think, becoming a broader area in psychiatry and general medicine with chronic illness: to look at chronic infections and the microbiome, and some of these infections are good for us.

Peter L. Salgo, MD: We’re going to get guideline changes going forward?

Patricia V. Smith: Yes. I think we need to get guideline changes, and the reason that we need to is because, even though I know the IDSA is coming out with their guidelines in early 2018, my understanding is they didn’t last time—and I’m guessing that they won’t this time—include anything for patients with chronic disease or post-treatment Lyme, whatever you want to call it. And so, that is very problematic, the same way with the CDC MMWR article. The way they have, in a little box in the side of the article, put in that they do not recommend any antibiotic treatment or IVIG treatment for chronic Lyme because, of course, we know chronic Lyme doesn’t exist. So, now you leave a whole plethora of patients out there without any kinds of options. They’re not allowed to have alternative medicine and they’re not allowed to have extended antibiotics, which are not alternative medicine. Tuberculosis patients get treated for 2 years with IV antibiotics.

Leonard Sigal, MD: And there’s a reason for that, Pat. There’s a reason for that, and that is the lack of really rigorous science in support of those approaches.

Patricia V. Smith: I agree with you.

Leonard Sigal, MD: What I’d like to see is cooperation between the 2 ends of the spectrum, proper studies.

Patricia V. Smith: I’m totally in favor of that.

Peter L. Salgo, MD: I need to stop right here. I’m going to go around and everybody is going to get a last word. You’re going to get it, too. Dr. Bransfield, start. This is your shot.

Robert C. Bransfield, MD, DLFAPA: So, William Osler, the father of medicine, once said, “To know syphilis is to know medicine.” But I think we could look at that in terms of Lyme disease, and to know Lyme disease, you really have to know not just medicine, but also psychiatry, entomology, epidemiology, immunology, psychoimmunology, rheumatology, and politics.

Leonard Sigal, MD: Throw cardiology in as well.

Robert C. Bransfield, MD, DLFAPA: And cardiology. You need a broad capability that’s beyond the training of most people. So, the big thing we have to add is some humility. We can’t have arrogance. We have to know that a lot of the answers to this are outside our field of specialty, so we have to have open dialogue, open communication like we’re having here, and that’s what will help resolve this.

Peter L. Salgo, MD: Dr. Shor?

Samuel Shor, MD, FACP: Well, it’s important, I think, to recognize that chronic active Borrelia infection exists. What is most contentious is this post-treatment component, which I’ll get to in a second. But what is often disregarded are those who never get diagnosed and are untreated. We have an expanding tick population, and the percentage of ticks are increasing that are actually infected. The majority of patients never recognize they’ve been bitten by a tick. There’s a large percentage of them who don’t have the hallmark feature EM rash, and if they do, it’s often in a hidden place, or it may be atypical. They present with common symptoms—summer flu. Then, throw in the post-treatment group that can potentially present in similar manners with chronic disease. We’ve already alluded to that there’s good evidence of persistence after requisite antibiotics. Not everybody who’s chronically ill after treatment has active infection, but I would argue that a modest percentage do. And so, we need to be empathetic in dealing with this chronic fatigue, chronic pain, and cognitive impairment, this complex group of individuals who, unfortunately, because of poor lab testing and the politicization of this condition, are often peripheralized.

Peter L. Salgo, MD: Dr. Sigal?

Leonard Sigal, MD: In clinical medicine, have an open mind and an open heart. To rephrase what you were saying, we have to have humility, absolutely. We don’t know everything. We have to be open to the possibilities of it being Lyme disease, being another infection, being something else entirely, being immune meditated or inflammatory mediated. You have to be aware of all the potential mechanisms, and you have to be humble in the sight of all these competing potentials. You have to have an open mind and ultimately, even if I can’t make a diagnosis, the person who’s sitting in front of me is suffering. And to show that person the door without any sense of what we’re going to do next is cruel and should not be the practice of any physician. So, an open mind, open heart, clinical practice, and better science. We need to stop arguing with each other, and we need to stop pointing fingers, and we need to be able to move on and say, ultimately, that the only important thing is the patients are suffering. Ergo, I agree: power, I agree; money, I agree. We have to throw out those things and get beyond ourselves and sit down and come up with the studies, mutually agreeable studies, that will allow us to come up with biomarkers; better sero-confirmatory tests, they’re not diagnostic tests; and better approaches to therapy. Anything short of that is an abdication of our primary responsibility, which is to practice scientific and empathic medicine.

Peter L. Salgo, MD: And I promised you the last word.

Patricia V. Smith: You did.

Peter L. Salgo, MD: And I’m keeping my promise. Go ahead.

Patricia V. Smith: I want to speak to the fact that, for many decades now, patients and advocates have been left out of this process of Lyme disease. And by that I meant they’ve been excluded. Other diseases have had committees for years that have sat in Washington, and they’ve sat with these working groups, and they’ve been able to have input on their diseases. Patients have been totally excluded. It’s very frustrating for them. It has caused, in my opinion, some of this bad science, because the educated patients know what kind of studies they need to help them with their disease. They just want to get better. They don’t care about these arguments, they want to get better. They’ve never been able to sit down like this.

So, finally, I’m pleased to say that last year we were successful for the first time, after a lot of opposition from the IDSA and others over the years, in getting legislation passed and included in the 21st Century Cures Act. That provides a working group that—there’s a working group now in Washington—only includes federal officials at the table. They have been making all the decisions for patients. That is really outrageous. And so now, patients, because of the way we set this up, will have a seat at the table, perhaps an advocate, or a member of a Lyme organization will have a seat. Our treating physicians who have never had any input into this process—guess what they’re going to be doing. They’re going to be working with all the different agencies to find out what the resources are that are available for research, what kinds of studies need to be done, and it’s also going to be done in a transparent fashion, whereas now it’s behind closed doors. No one knows what research is selected until after it’s done, and then you have no say in the matter. I just say for Lyme patients, the time has come when they will get a seat at the table, to be able to have input about their disease.

Peter L. Salgo, MD: Alright. Well, thank you all for being here. You can all take off your flak jackets and your helmets. This has been a tremendous discussion, one of the best in my career, and I’m glad we all got at the same place at the same time to discuss what has been one of the most contentious issues in modern American medicine. On behalf of our panel, I want to thank you for joining us, and I hope you found this Peer Exchange® discussion to be useful and informative. I’m Dr. Peter Salgo, and I’ll see you next time.

What We Can Learn From The French About Fighting Lyme Disease

Part of our Losing to Lyme series

Most visitors go to the Alsace region of France to drink its fine white wines and to Lorraine for its ornate architecture. I went to see if the French are dealing with Lyme disease better than we are here in Massachusetts and across the U.S.

Last September, France became the first country to release a national plan to address tick-borne diseases like Lyme. It ranges from ramped-up surveillance of ticks and infections to better treatment protocols and diagnostic tests.

In May, Canada released its own federal action plan to address Lyme. In the United States, we have at least 10 times more cases of Lyme than France or Canada: over 300,000 cases annually, compared to about 33,000 in France and probably less than 10,000 in Canada. But we lag far behind on concerted national action, even as the problem of tick-borne diseases continues to grow.

So what can we learn from the French? A lot, I concluded. The officials, doctors and researchers I spoke with there emphasized that their national plan is still evolving. But already they are launching a sweeping initiative to tackle Lyme disease as a major public health problem.

An All-Hands-On-Deck Approach

Tune in to French radio this summer and you might hear this: Birds chirping, footsteps crunching on forest leaves, and a woman asking, “Ehhh, have you thought about protecting yourself against ticks?”

C’est bon,” her male companion responds jovially. “The little beast won’t eat the big one.”

The woman shares a few anti-tick tips to avoid catching la maladie de Lyme, and the spot finishes up with a slogan: Against ticks — tiques in French — “to be watchful is to win.”

The 30-second spot from France’s public health agency is one of many on the airwaves this summer; others include experts answering questions about ticks and Lyme disease itself.

You’ll also find posters detailing how to prevent tick bites in pharmacies, medical clinics and even the Alpine Club of Nancy, housed in an art nouveau building just off the famous Place Stanislas downtown.

At the entrance to forests in eastern France — in Kintzheim in Alsace, or La Haye in Lorraine — you’ll find more “beware of ticks” signs, with tips on what to look for and how to remove them.

France doesn’t have a magic prevention toolkit. In fact, much of what they’re doing — education, tracking ticks and counting Lyme cases — is similar to what we do, some of it at the federal level and some of it piecemeal, at the local level. They’re just doing much more of it, more thoroughly and robustly, than we do.

And they don’t need to rely on local public health heroes, as we often do in the United States. Here in Massachusetts, the heroes include Larry Dapsis, the entomologist for Barnstable County, who spends the spring and summer doing 70 tick-borne disease workshops up and down Cape Cod. Or Catherine Brown, the state public health veterinarian, who finds time among her innumerable responsibilities to also teach the public about Lyme. Their personal passion is key because their tick-related work runs on a shoestring.

France, in contrast, is putting strong systems in place and attacking the problem from multiple angles — coordinating between government agencies and recognizing that the complex problem of Lyme disease requires multiple simultaneous solutions.

“If we do a good job at prevention, we’ll have fewer patients who end up seeking care and struggling in the medical system,” said Lucie Chouin, a public health official for the Greater Eastern region of France. “For me, prevention is part of a package; if we only do so much, and do not do anything upstream, the problem won’t be resolved.”

And France is allotting the money to take that holistic approach. Though it does not specify a budget, the national French plan sets the priorities at high levels of government. The then-minister of health herself, Marisol Touraine, announced the release of the national plan this past September.

2,000 Forest Signs

Take education. Along with those radio spots and posters in the northeast of France, the government is paying to educate hundreds of doctors and place thousands of pamphlets in medical offices. At the cost of about 1,000 euros each it’s placing 2,000 of those “beware of ticks” signs across the country.

That is a much more sweeping and energetic program than I’ve seen in the Lyme hotbed of Massachusetts, which leaves most Lyme disease issues to local officials. The state produces free educational materials, but it’s up to towns to use them. If a town wants to go beyond education — which experts think will be required to turn the tide against tick borne illnesses — they need to drum up the cash. So far, few towns do.

Compare that to what the all-hands-on-deck approach against Lyme looks like in France. Initiatives there, in addition to better educating the public, include:

  • Public health “Regional Intervention Units” to track Lyme and tick-borne diseases better, including an ongoing multi-year study of the number of Lyme cases in the Lyme-heavy northeast region
  • The Agricultural Social Mutual Fund, a social security system to protect agricultural workers, is supporting pamphlets and a push to pinpoint tick hot spots
  • And the medical system and the public health department are doing most of the heavy lifting to carry out the national plan

Pragmatic Science

Here’s something else France has that we don’t: an app that lets everyone report tick bites on themselves or their pets. It’s called Signalement Tique and was just released by the National Institute for Agricultural Research in July.

The app is just one of many French initiatives under way to improve research on ticks and Lyme. The national plan puts heavy emphasis on practical research, and the ecology research that is crucial for fighting Lyme does not fall through funding cracks as it does here in the U.S.

Here, about two-thirds of our annual Lyme research spending is on basic biology. Research budgets tend to be smaller in France, but the emphasis is also different — more focus on projects that have immediate practical applications, such as identifying local tick hotspots or tracking what proportion of ticks carry diseases.

“We get money from time to time, and we’re used to working with less money for basic research,” said Benoit Jaulhac, an expert on Borrelia — the Lyme bacterium — and director of the National Reference Center for Borrelia in Strasbourg, where all French Lyme researchers are located. (No, we don’t have one of those either.)

But because some funding comes from the Institute for Public Health Surveillance, much of their research must yield “immediately applicable information,” Jaulhac said, such as tick-tracking and diagnostic tests. Few resources go to tick-tracking here; public health official argue that it is because tick numbers can vary dramatically from spot to spot, but another reason is that most simply don’t have the money for it.

Some particularly intriguing French research still in the planning phase: a study on what happens to people who get tick bites, looking not just at tick-borne illness but at whether the tick bites themselves could make people chronically sick over time.

The National Borrelia Center is also working with the the National Institute for Agricultural Research on tick surveillance and ecology research to figure out what could stem the tick invasion. In the U.S., the focus on basic biological research leaves ecologists often struggling to find grants to fund their tick-borne disease research.

Months Of Medical Care In A Day

Abdel Hafiz Abid can remember the exact day he became ill: July 5, 2014. He started to feel pain in his left leg, and particularly his ankle. At first it was occasional, but soon it afflicted him every day, and extended to his knees and back. He was also beset by fatigue — “Walking 200 meters feels like I’ve walked 25 kilometers,” he said — and by problems with short-term memory.

Family members suggested he had Lyme disease. “We vaguely talked about it, like everybody else,” he said. A number of them have that diagnosis, and he lives outside the city of Metz, in the Lorraine region of northern France, which has one of the country’s highest rates of Lyme.

The testing began. In a 2-inch black notebook, Abid keeps multiple yellow folders from each different laboratory and clinic he’s visited on his quest for a diagnosis. He’s been to clinics in France and one in Germany, spent thousands of euros outside what the national health plan covers, and tried multiple courses of antibiotics, some as long as six months. So far, nothing has worked.

So he came recently to Nancy, the biggest city in Lorraine, to spend the day at a new multi-disciplinary Lyme disease clinic run by Dr. François Goehringer, an infectious disease doctor.

“Ten years ago we used to say, ‘It’s not Lyme, we don’t know what it is,’ and they left our clinic with us saying, ‘We know you’re sick, but we don’t know what it is, au revoir, monsieur, au revoir, madam,'” Goehringer explained. Patients would then bounce from specialist to specialist getting different, confusing answers.

“We decided we could gain a lot of efficiency by trying to offer a day of hospitalization at the center of our approach,” he said. “The maximum of complementary exams and specialist advice to be able to weigh in on what the patient is suffering from.”

There are many specialized Lyme clinics in France and in the United States as well. What makes the Nancy clinic stand out is that one-stop shop organization. For a day, patients come to the hospital, get all the tests and scans, see various specialists and get started on treatments that fit their diagnosis.

Goehringer and his intern, Dr. Marie Geisler, go through Abid’s black folder in detail, reviewing all prior test results and consultations. Geisler sits with Abid to fill out the 10-page “Multidisciplinary Diagnostic Approach for Patients Suspected of Lyme,” a standardized questionnaire. There’s a cognitive assessment as well. Geisler then does a thorough, 30-minute physical exam, an EKG, and reports her findings to Goehringer.

Almost all of Abid’s tests for Lyme and other diseases are negative, except one 100 euro test from Germany that often returns false positives. His western blots, which would confirm the presence of proteins related to the Lyme bacteria, are all negative.

“He has no objective evidence of Lyme,” Goehringer said after reviewing all the files. But Abid’s parathyroid hormone  which controls calcium and bone health  is elevated. It could be an explanation for some of Abid’s symptoms. Endocrinologists aren’t part of the Lyme clinic, but Geisler books him for a rapid follow-up appointment to check into it.

Like all patients who come to the clinic, Abid also sees Lorraine Callins, a psychologist who specializes in chronic illness and hypnotherapy. Many of her chronic autoimmune disease or hemophilia patients “feel abandoned by medicine, so they seek other roads,” she says.

If his symptoms warranted it, Abid would also have seen a rheumatologist or neurologist – common specialties for people with suspected Lyme symptoms.

Goehringer sees only four patients every Friday and has seen about 100 patients total since the one-stop-shop program began in January. He also aims to start a monthly meeting of various specialists to develop plans for some of the most challenging patients.

Some American clinics hope to organize similar one-stop shops. But since we have a fee-for-service system, expensive specialists are difficult to organize unless there is sufficient patient volume. It’s not impossible here, but it’s quite a financial challenge.

France faces its own challenges: The national Lyme plan aims to improve medical care, including with clinics like Goehringer’s, and sets ambitious targets to develop standardized treatment guidelines by the end of 2017. That appears unlikely, with doctors and Lyme advocacy groups still far apart on what the guidelines should be.

But while standardized guidelines are in the works, the Nancy clinic will at least offer a respite for patients who have spent months seeing myriad specialists in search of a diagnosis.

Will it improve outcomes? It’s too early to tell, but at least from the patient’s point of view it’s a step forward as it streamlines what is usually a months-long process into a single day.

Crossing Cultures

Maybe my starting point — What we can learn from the French? — wasn’t a fair one. We have deeply different health systems that reflect different cultures. France provides some of the best overall health care in the world and has a long tradition of viewing health care as a right, even enshrined in their constitutions.

It also has a national health system that pays for medical care. In this cultural context, spending on public health and prevention isn’t just seen as the right thing to do, but a way to reduce health costs later.

In contrast, in the U.S. we spend the most money on health care per person in the world, but don’t get more bang for our buck.

There are some hopeful signs of support for our fight against Lyme disease: The U.S. federal government has recently committed $40 million to create four regional centers of excellence for vector-borne diseases — which include Lyme — as part of its efforts to control the Zika virus.

But most of that money is expected to go toward fighting Zika, so it will likely do little to help fill the public health funding gaps that are leaving us far behind France in the fight against Lyme.

**Comment**

  • The 40 million going to regional centers for excellence in the U.S. needs to be watch-dogged as the author is correct in his statement that the preponderance of that money will be ear-marked for Zika, a disease that has caused 254 symptomatic cases of which 251 are from travelers returning from affected areas (outside the U.S.), 0 cases through presumed local mosquito-borne transmission, and 3 cases acquired through sexual transmission.  https://www.cdc.gov/zika/reporting/2017-case-counts.html The CDC currently is estimating over 300,000 new cases of Lyme Disease EACH YEAR and the true number to likely be much higher.  https://www.cdc.gov/lyme/stats/humancases.html

Anyone out there see the disparity yet?
