Sick Lyme Patients Causing Scientists to Feel Threatened

This absolutely made my day.  Power to the sickies!

https://www.buzzfeed.com/stephaniemlee/lyme-disease-patient-registry?utm_term=.wbLADWmea#.ylXj5dzp4  Buzzfeed News, by Stephanie M. Lee

In late 2015, Lorraine Johnson was frustrated with what she felt was the slow progress of research on Lyme disease, the tick-borne rash that strikes thousands of Americans every year, in apparently increasing numbers. So as the head of LymeDisease.org, a leading advocacy group, she launched her own study: MyLymeData.org.

The site has since surveyed 7,000 people, Johnson reported this month at a conference in the San Francisco Bay Area. The site calls itself “the first national large-scale study of chronic Lyme disease.”

It’s one of the newest large online registries built by patients with rare or understudied conditions. Feeling ignored by academics and Big Pharma, they turn to the internet, where they can pool the collective wisdom of people who might otherwise never enroll in a clinical trial.

We don’t feel ignored, WE ARE IGNORED!  https://madisonarealymesupportgroup.com/2017/04/22/mylymedata-presentation/  Only 3 small clinical trials on the treatment of chronic Lyme disease were funded by the NIH – the most recent was 15 years ago.  Hello?

Scientists are increasingly relying on apps and websites like this one to conduct research. But as this approach becomes more popular, researchers have questions about its inherent lack of rigor and standardization.

Online surveys typically don’t require proof of a diagnosis, and self-diagnosis is often tricky. For example, the varied symptoms of Lyme disease — arthritis, fever, headaches, shooting pain, and memory problems, among others — crop up in many other conditions, making it difficult to identify conclusively, even for doctors. It’s also tough to keep people engaged in a study when they’re scattered across the country.

“The ability to get big data on large numbers of people fairly easily, that’s a strength,” said Dr. John Aucott, director of the Lyme Disease Clinical Research Center at Johns Hopkins University, who is not involved with MyLymeData. “The advantage is you’re getting patient symptoms — but the disadvantage is you don’t truly know they’re due to Lyme disease.”

Despite these potential issues, self-reported patient data could soon help pharma companies bring drugs to market faster. Under the 21st Century Cures Act, passed in December, companies applying for certain kinds of FDA drug approvals can submit data about how patients are reacting to drugs in the real world, rather than data collected from rigorously controlled clinical trials. Critics say this provision weakens regulatory oversight.

“In terms of generating really good evidence that you’re going to make people better off, [real-world data] is a good starting point, but it’s not the finish line,” said Vinay Prasad, a hematologist-oncologist at Oregon Health and Sciences University.

Around 300,000 people in the United States, almost entirely in the Northeast and upper Midwest, are diagnosed annually with Lyme, according to the Centers for Disease Control. The agency has clear criteria for diagnosing Lyme in its early days, including a tick bite, a bull’s-eye rash, and a lab blood test. A few weeks of antibiotics cures most patients. But some experience symptoms like headaches and joint and nerve pain for months, even years, after treatment.

The federal government has funded only a handful of Lyme disease studies, and one of the larger ones, published in 2001, enrolled just 130 people. All of the studies focused on patients who had symptoms even after taking antibiotics. Patients often call this advanced stage “chronic Lyme disease,” as does MyLymeData, though most doctors argue that this term has come to mean many things to different people and has no accepted definition. They and the CDC instead use “post-treatment Lyme disease syndrome.”

Johnson says that she created MyLymeData to make up for this dearth of research on patients with lingering symptoms. “The problem with Lyme disease is essentially there is no data,” she told BuzzFeed News.

She doesn’t know of any cures or treatments in the works for Lyme patients who don’t respond to antibiotics — but hopes her database will inspire pharmaceutical companies to develop some.

The people who have signed up for MyLymeData, she said, “were just very anxious to push forward research because research had really kind of left them behind,” she said

At a conference hosted last fall by the Lyme Disease Association and Columbia University, Johnson presented findings from an unpublished survey of more than 4,000 MyLymeData participants. The survey responses showed that people who were diagnosed at an early stage were more likely to report being healthy than those who were diagnosed later, and many claimed that their doctors had failed to accurately spot the disease. Johnson said at the time that the findings showed both the need for physicians to make diagnoses early on, and for “more effective treatments to help those patients who remain ill.”

But experts note that MyLymeData’s database may not accurately reflect Lyme patients, particularly those with persistent symptoms, the hardest stage to diagnose.

For Aucott of Johns Hopkins, making a diagnosis of post-treatment Lyme disease syndrome is a painstaking process. There isn’t one clear biomarker, like a genetic mutation or an X-ray reading, that proves someone has the condition. He and a nurse interview a patient, then review all of their medical records and lab reports, to establish both that they were healthy before getting diagnosed and showed Lyme symptoms after their antibiotic treatment. Aucott also tries to figure out if they might have anemia, thyroid disease, chronic fatigue syndrome, or something else with similar symptoms.

“I’ve seen 500 or 1,000 patients with decades of work,” Aucott told BuzzFeed News. “That’s the level of detail you need to really be convinced you have a uniform population.”

He and other experts told BuzzFeed News that they’re worried that MyLymeData allows, but doesn’t require, people to provide lab readouts and doctors’ notes to prove which stage of disease they’ve had, or even that they ever had the disease. To sign up, participants simply need to check boxes saying they live in the United States and have been diagnosed for Lyme by a health care professional. Then they answer a barrage of questions, such as how many times they’ve been infected, when they were first infected, and which symptoms they’ve had. (To test the service, a Lyme-free BuzzFeed News reporter successfully signed up and filled out responses about her nonexistent condition.)

“I’m not sure this kind of registry would be super helpful other than to tell you a little bit about what patients who have been labeled with ‘chronic Lyme’ complain about or have been treated for it,” said Paul Auwaerter, a professor of medicine and Lyme specialist at Johns Hopkins.

Others question how well the database represents actual patients.

“The problem with Lyme disease is essentially there is no data.”
“If the data are based on volunteered testimony, how do we know that those who choose to volunteer adequately represent those who don’t?” Paul Lantos, an assistant professor of internal medicine and pediatrics at Duke University School of Medicine, said by email. “If recruitment is promoted by advocacy groups, then how do we know those who volunteer represent Lyme disease patients more broadly?”

Johnson admitted that MyLymeData relies on the honor system, but pointed out, “I don’t think 7,000 people would take the time to go through and complete the surveys and do the follow-ups if they didn’t have a diagnosis.”

And, she said, the beauty of the database is that if a researcher wanted to study something about biomarkers, they could easily contact people through MyLymeData and ask for their lab reports and other medical records. She says that she and the academic researchers she’s working with, whose names she declined to share, will always be careful to point out the limitations of their research.

“It is possible to glean accurate insights about diseases from self-reported data,” says Ben Heywood, president and co-founder of PatientsLikeMe, a website where patients go to discuss their conditions. But, he added, “it takes ‘a fair amount of manual curation’ to make the data useful for research institutions that team up with the company, such as the FDA.”  PatientsLikeMe members have reported more than 30,000 treatments and symptoms for various illnesses, which staff then translate into medical terms (such as translating “chemo brain” into the more technical term, “cancer treatment-related cognitive impairment”).

“Doing real-world evidence or patient-generated health data in a rigorous scientific and methodological way, the way we do it, is hard,” Heywood said.

It’s understandable that chronic Lyme patients would want to take matters into their own hands after feeling ignored by mainstream doctors.

“I definitely think that many patients feel alienated from the ‘conventional’ medical community,” Lantos wrote. ‘This project may help us understand where our communication fails patients.”

Online patient registries like MyLymeData are becoming more and more common; by one count, there are 20. The earliest ones were dedicated to patients with rare, lethal diseases like cystic fibrosis and muscular dystrophy, and now there are ones about cardiovascular health and Alzheimer’s disease.

“Registries will likely proliferate under the 21st Century Cures Act,” says Kim McCleary, managing director of FasterCures, a think tank that was a key supporter of the legislation. And as for concerns that their kind of data threatens scientific standards, McCleary counters that it’s not an either-or question.

“I don’t think anyone expects [patient data] is going to replace double-blind placebo-controlled trials,” she said.

US Soldier Acquires Tickborne Relapsing Fever Caused By B. Turicatae From a Ornithodoros Turicata Tick

https://wwwnc.cdc.gov/eid/article/23/5/16-2069_article

Christensen AM, Pietralczyk E, Lopez JE, et al. Diagnosis and Management of Borrelia turicatae Infection in Febrile Soldier, Texas, USA. Emerging Infectious Diseases. 2017;23(5):883-884. doi:10.3201/eid2305.162069.

Abstract

In August 2015, a soldier returned from field exercises in Texas, USA, with nonspecific febrile illness. Culture and sequencing of spirochetes from peripheral blood diagnosed Borrelia turicatae (a species of borrelia) infection. The patient recovered after receiving doxycycline. No illness occurred in asymptomatic soldiers potentially exposed to the vector tick and prophylactically given treatment.

Tickborne relapsing fever (TBRF) was first reported in the United States >100 years ago but is often difficult to identify, given its rarity and variety of clinical presentations (1,2). We describe a case of culture-confirmed TBRF caused by Borrelia turicatae acquired by an Army soldier during a military training exercise in Texas, USA.

The patient was a 31-year-old white man with no relevant medical history. In August 2015, he sought care at the Eglin Air Force Base Hospital (Valparaiso, Florida, USA) with a 5-day history of fever (102°F), chills, and myalgias. He reported headache and nausea but no vomiting or diarrhea. He denied localized joint pain, redness, or swelling but had discomfort in both popliteal fossae (back of both knees).

The patient had recently returned to Florida after a 30-day Army exercise under austere conditions in western Texas (Technical Appendix[PDF – 376 KB – 3 pages] Figure 1). Potential exposures included sleeping nude in a sleeping bag on the floor of an abandoned barn that had been cleared of infestation with rabbits, rodents, birds, and bats; having eaten boar that had been slaughtered, dressed, and cooked over an open flame; and consuming water procured from a well, bottled sources, and at times through a LifeStraw http://lifestraw.com/. Approximately 1 week before admission, he had noted multiple skin lesions, including scattered, presumed insect bites along his left leg and a small lesion at his urethral meatus (where urine exits). He denied any history of genital lesions and had not seen any biting insects. After 6 days, the lesions spontaneously resolved.

In a Texas emergency department, the initial diagnosis was viral syndrome, and a rapid influenza test result was negative. The fever persisted despite administration of antipyretics. After 2 days, the patient returned to the hospital, where he received only symptomatic treatment. No tests were ordered. After another 2 days, he sought care from his unit physician. Laboratory tests showed marked thrombocytopenia (low platelet count) with 16 × 109 platelets/L (reference range 150–400 × 109 platelets/L). Spirochetes were seen on peripheral blood smear (Technical Appendix[PDF – 376 KB – 3 pages] Figure 2). He was referred for hospital admission. Physical examination findings were unremarkable: no splenomegaly, hepatomegaly, or rash. Blood cultures and serologic testing for rickettsiae, HIV, dengue virus, Treponema pallidum, and plasmodia produced negative results. Erythrocyte sedimentation rate (58 mm/h) and C-reactive protein level (>19 mg/L) were elevated. Electrolytes and transaminase levels were within reference ranges.

Serum samples collected at admission and 3 weeks later (≈5 and 26 days after illness onset, S1 and S2, respectively) were tested in parallel at the Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases, Division of Vector-Borne Infectious Diseases (Fort Collins, CO, USA) by enzyme immunoassay and Western blot (IgM and IgG) for TBRF antibody reactivity. Seroconversion was demonstrated by rising enzyme immunoassay values (S1 = 0.79, S2 = 2.41; equivocal range 0.64–0.91) and separate IgM and IgG Western blots (Technical Appendix[PDF – 376 KB – 3 pages] Figure 3). In addition, the samples demonstrated seroconversion (S1 = 0.91, S2 = 3.23; equivocal range 0.90 –1.09) against C6, an immunogenic antigen conserved among Borrelia spp. (Borrelia burgdorferi ELISA; Immunetics, Inc., Boston, MA, USA).

Spirochetes were successfully cultured, and genomic sequencing determined that B. turicatae was the causative agent (3). The patient improved rapidly with doxycycline, and platelet count normalized within 2 weeks. Ten asymptomatic soldiers with similar exposure were identified and prophylactically given doxycycline; 24 asymptomatic soldiers who had been in the area but not in the same barn as the patient were monitored closely. No additional illnesses were detected.

TBRF is a neglected and probably underdiagnosed disease. The vector, the Ornithodoros turicata tick (soft bodied tick – picture here:  https://en.wikipedia.org/wiki/Ornithodoros_turicata), is endemic to Texas and Florida (4); but although published cases in Texas have been supported by serology for the TBRF group, exposure location, and tick collections (4,5), to the best of our knowledge, successful identification of B. turicatae in a human has not been reported. Previously, B. turicatae has been isolated only from ticks and canids (foxes, wolves, dogs, jackals, and coyotes) in several areas of Texas (4–6).

The ecologic setting of the military exercises was predictable for high-risk exposure to the tick vector. TBRF attack rates >22% have been reported for group settings with sequelae severe enough to warrant hospitalization (7,8). Military training groups in Israel have declared certain caves off limits because of heavy tick presence (9) and have prophylactically administered doxycycline to those suspected to have been exposed (7). There has not been an association of Jarisch-Herxheimer reaction in asymptomatic patients receiving doxycycline (7), although this reaction is common during treatment of patients with active illness (9).

We identified several difficulties in epidemiologic awareness and diagnosis. There is overlap of bacterial, viral, and parasitic pathogens in location and nonspecific symptom presentations. The O. turicata tick bite is rarely noticed or reported because the vectors are rapid nocturnal feeders, attachment is painless, and often no lesions or ticks are discovered (10). This case report with successful isolation and genetic characterization of B. turicatae from the soldier (3) confirms that this spirochete species is a zoonotic pathogen. The initial misdiagnosis further indicates the neglected nature of this disease, especially in the military population.

Co-infection of Ticks: The Rule Rather Than the Exception

Abstract

Introduction

Ticks are the most common arthropod vectors of both human and animal diseases in Europe, and the Ixodes ricinus tick species is able to transmit a large number of bacteria, viruses and parasites. Ticks may also be co-infected with several pathogens, with a subsequent high likelihood of co-transmission to humans or animals. However few data exist regarding co-infection prevalences, and these studies only focus on certain well-known pathogens. In addition to pathogens, ticks also carry symbionts that may play important roles in tick biology, and could interfere with pathogen maintenance and transmission. In this study we evaluated the prevalence of 38 pathogens and four symbionts and their co-infection levels as well as possible interactions between pathogens, or between pathogens and symbionts.

Methodology/principal findings

A total of 267 Ixodes ricinus female specimens were collected in the French Ardennes and analyzed by high-throughput real-time PCR for the presence of 37 pathogens (bacteria and parasites), by rRT-PCR to detect the presence of Tick-Borne encephalitis virus (TBEV) and by nested PCR to detect four symbionts. Possible multipartite interactions between pathogens, or between pathogens and symbionts were statistically evaluated. Among the infected ticks, 45% were co-infected, and carried up to five different pathogens. When adding symbiont prevalences, all ticks were infected by at least one microorganism, and up to eight microorganisms were identified in the same tick. When considering possible interactions between pathogens, the results suggested a strong association between Borrelia garinii and B. afzelii, whereas there were no significant interactions between symbionts and pathogens.

Conclusion/significance

Our study reveals high pathogen co-infection rates in ticks, raising questions about possible co-transmission of these agents to humans or animals, and their consequences to human and animal health. We also demonstrated high prevalence rates of symbionts co-existing with pathogens, opening new avenues of enquiry regarding their effects on pathogen transmission and vector competence.

Author Summary

Ticks transmit more pathogens than any other arthropod, and one single species can transmit a large variety of bacteria and parasites. Because co-infection might be much more common than previously thought, we evaluated the prevalence of 38 known or neglected tick-borne pathogens in Ixodes ricinus ticks. Our results demonstrated that co-infection occurred in almost half of the infected ticks, and that ticks could be infected with up to five pathogens. Moreover, as it is well established that symbionts can affect pathogen transmission in arthropods, we also evaluated the prevalence of four symbiont species and demonstrated that all ticks were infected by at least one microorganism. This work highlights the co-infection phenomenon in ticks, which may have important implications for human and animal health, emphasizing the need for new diagnostic tests better adapted to tick-borne diseases. Finally, the high co-occurrence of symbionts and pathogens in ticks, reveals the necessity to also account for these interactions in the development of new alternative strategies to control ticks and tick-borne disease.

To which we all said AMEN!

A few notes on the study:  To see a chart showing exactly what coinfections and symbionts they looked at, go to the link for the study.  They looked at 6 strains of borrelia (Lyme), Anaplasma, Ricketssia helvetica, Bartonella, Babesia, and Neoehrlichia mikurensis (Order: Rickettsiales, Family: Anaplasmataceae).  The symbiots looked at were:  Wolbachia, Spiroplasma, Acinetobacter, and Midichloria mitochondri.

While I am unfamiliar with most of the symbionts, Wolbachia concerns me as scientists are actively inserting Wolbachia into mosquitoes and releasing them into the wild in efforts of eradicating Dengue Fever, Chikungunya, yellow fever, and possibly even Malaria.  While scientists claim Wolbachia, a gram-negative bacterium in the family of Rickettsiales, can not infect humans, they can and do infect worms which cause human disease.  Since nematodes have been found in ticks and many Lyme/MSIDS patients have to treat for worms, the question begs to be asked, “Does Wolbachia play a role in Lyme/MSIDS?”  This is a question I plan on writing about, but the answer could very well be, “Yes.”  I certainly pray that more research on Wolbachia in relation to Lyme/MSIDS is done as this could definitely be a fly in the proverbial ointment.

Lastly, I believe recorded coinfection numbers to be abysmally low.  My own LLMD doesn’t even test for them, he feels the tests are that poor.  Also, probably the numbers reflect the most severe cases – leaving many out.  As you are aware, coinfections are notorious for presenting differently than the textbook presentations that most doctors are familiar with. Dr. Horowitz writes and speaks about this often.

Published on Nov 3, 2014
At the “Symposium on Tick-borne Diseases” held May 17, 2014

37:30 You will only find a positive test for Babesia if the level of parasitima in the blood is greater than 5%.  38:05 Medical textbooks also state you should have hemolytic anemia, thrombocytopenia, and renal failure if you have Babesia.  Dr. Horowitz states he has not had one Lyme/MSIDS patient present this way.  

How many doctors are going to think outside their medical textbooks?

More Powassan in Maine

http://vitalsigns.bangordailynews.com/2017/04/26/home/tick-researchers-found-powassan-virus-in-these-maine-towns/

Since 2013, when a Maine woman died from Powassan, two more cases have been reported there and have caused encephalitis, but thankfully, not death.

This has prompted a statewide survey to discern just how many Maine ticks carry it. The researchers were surprised at the results.  Results here:  https://drive.google.com/file/d/0ByNSaqVer3roR3QxQTU2MGRDbTQ/view

All three contracted Powassan during the adult tick seas in fall and early spring and 7% of the adult ticks carried the virus.  To date, Powassan has been found in the deer tick (deer tick virus) as well as the groundhog or woodchuck tick.  There’s evidence both strains are in Maine.

For more on Powassan:  https://madisonarealymesupportgroup.com/2016/02/21/powassan-virus/

While transmission time for Powassan has been established to occur within about 15 minutes, I was very thankful that the article gave both the official word on transmission times for Lyme Disease (the erroneous 36-48 hours or more) as well as a link to an article about Dr. Nevena Zubcevik which debunks numerous myths, including the “official” transmission time myth. http://www.mvtimes.com/2016/07/13/visiting-physician-sheds-new-light-lyme-disease/

I recently wrote about this myth that needs to die:  https://madisonarealymesupportgroup.com/2017/04/14/transmission-time-for-lymemsids-infection/  (Includes a great video by microbiologist Holly Ahern explaining in layman’s terms about transmission times and what the studies actually say)

First Report of Malaria With Lyme Disease

http://danielcameronmd.com/first-report-malaria-lyme-disease-co-infection/#  by Daniel J. Cameron, MD MPH

“As far as we are aware, we are writing the first report of Plasmodium spp. and Borrelia burgdorferi co‐infection (a co‐infection of a tropical parasite and a non-tropical bacterium),” explains Neves from the Infectious Diseases Department, Centro Hospitalar São João, Portugal.  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5378865/

The man had returned to Portugal from Angola, where he worked as a welder. Four months earlier while living in Angola, he was diagnosed with malaria and treated with an outpatient regime. But upon his return to Portugal, the man complained of fever, constitutional symptoms, headaches and blurred vision.

Malaria was suspected based on examination of thin blood smears and rapid diagnostic testing. Anti-malarial treatment was initiated and consisted of intravenous quinine (600 mg q8 h) and IV doxycycline (100 mg q12 h).

“Atypical malaria has a broad differential diagnosis, of which co‐infections represent a cornerstone.”

But on the second day of admission to the hospital, the man developed an altered mental status with increased lethargy. Doctors suspected Lyme disease during a neurological evaluation, where he showed signs of confusion, disorientation and marked cognitive slowing. “A slight left central facial palsy was described, with no other cranial neuropathies,” states Neves.

“The concomitant diagnosis of borreliosis was based on clinical presentation and positive serology for Borrelia burgdorferi sensu lato,” according Neves. “Positive PCR for B. burgdorferi sensu lato in CSF also confirmed neuroborreliosis.”

The patient tested positive for Bb on the Western blot and treatment was altered to include intravenous ceftriaxone (2 g q12 h) for 14 days. The patient also required treatment for an autolimited antiphospholipid syndrome.

In conclusion, Neves points out the importance of considering co-infections. “Atypical malaria has a broad differential diagnosis, of which co‐infections represent a cornerstone. Making such a diagnosis is of vital importance in terms of management and prognosis. This is particularly true in the case of the co‐infection of B. burgdorferi, due to the potentially devastating neurological and systemic manifestations and the therapeutic implications.”
