LymeData 3-Mo Follow-up

https://www.mylymedata.org

If you haven’t done it already, make sure to fill out the follow-up to the MyLymeData Project which allows patients to pool their health information through a secure website. “Big data” projects use advanced technology to gather and analyze huge amounts of patient data, which can assist researchers in studying disease patterns and answering important questions such as why do some people recover from Lyme disease, while others remain ill?

If you’ve never heard of the project and would like to know more, please read:  https://madisonarealymesupportgroup.com/2015/11/11/lyme-research-project/

Your data, without your name or other identifiers, will be combined with the data of other patients and analyzed to help begin to answer important questions about the course of illness and factors that affect whether patients remain ill or become well.

The LymeDisease.org study team will analyze this data on its own and in partnership with researchers and clinicians who are interested in patient-centered research. Independent researchers working on patient-centered research projects approved by LymeDisease.org. may also analyze de-identified patient data.

LDo will provide information about its findings to the community through blogs, publication of white papers, and peer-reviewed articles.

Previous surveys have been published in peer-reviewed publications and used to inform healthcare policymakers on issues affecting the community.

The new follow-up includes a regular 3 month survey that tracks treatments, symptoms, treatment response and quality of life. It also includes a component about genetics, whether Lyme runs in the family, and other related illnesses (e.g. Parkinsons, Lupus etc) that people may have.  This survey is a regular quarterly survey to track treatment response and look at what treatments may be working.  There will also be a decedent survey that will allow people to enter information on behalf of someone who is deceased–for example, what was the cause of death?

If you want to share information about a Lyme patient who has passed away, there are two ways to do it. If you are enrolled in the program yourself, there is now a place to click to enter information about someone who has died. Otherwise, you can just join in that person’s name, and answer the questions on that person’s behalf. There’s a spot to indicate that you are answering for someone who has died.

Antibiotics and Alzheimer’s

Antibiotic restores cell communication in brain areas damaged by Alzheimer’s disease
November 15, 2016

New research from the Djavad Mowafaghian Centre for Brain Health at UBC has found a way to partially restore brain cell communication around areas damaged by plaques associated with Alzheimer’s disease.

The findings, published this week in Nature Communications, demonstrate a possible target and a potential drug treatment to reduce damage to the brain that occurs in the early stages of Alzheimer’s disease. Using Ceftriaxone, an FDA-approved antibiotic used to treat bacterial infections, researchers were able to reduce synaptic disruption and clear the lines of neuronal communication in mice.

Amyloid plaques of -amyloid deposits develop in brain regions of patients with Alzheimer’s disease, These plaques are linked to the damage found in Alzheimer’s disease because they prevent cell communication and are toxic to nerve cells. The researchers found that the brain areas around these plaques show high levels of glutamate, a signaling molecule essential to communication between brain cells, accompanying high levels of hyperactivity in glia, the brain’s support cells. It’s in this glutamate-rich environment that communication between neurons is changed or disrupted, causing neurons to die in the later stages of the disease.

“By imaging the glial cells and glutamate itself around the plaques, we were able to see that the cells were not able to ‘remove’ the glutamate accumulating in these brain areas. By using Ceftriaxone, we were able to up-regulate glutamate transport,” explains Dr. MacVicar, principal investigator and professor of psychiatry. “By restoring glutamate levels, we were able to mostly restore neuronal activity.”

The team’s findings have implications for treatment of early symptoms of Alzheimer’s disease.

“This dysfunction in cell communication occurs at a very early stage in the disease, before memory impairment is detectable,” says Dr. Jasmin Hefendehl, a former Postdoctoral Fellow in Dr. MacVicar’s lab and the lead author on the paper. “This makes our discovery particularly interesting, as it opens a window for an early intervention strategy to possibly prevent or delay neuron and memory loss.”

Ceftriaxone is an antibiotic that is commonly administered before some types of surgery to prevent infections. Although a recent clinical trial failed to see improvements for treating amyotrophic lateral sclerosis (ALS), the researchers are hopeful about its potential for early intervention in treating Alzheimer’s disease.

Due to the link between infections such as MSIDS (Multi systemic infectious disease syndrome – or Lyme with friends), and Alzheimer’s, this is encouraging news.  It shows the very real possibility that certain antibiotics will help.  Again, it appears the earlier the better.

Will Two Pills of Doxy Prevent Lyme?

Created by Lyme Action Network

Only one study in 2001 tested this hypothesis at one hospital in New York.

For the study, the bullseye rash was the diagnostic criteria to determine if doxy prevented LD. The study actually showed that people bitten by nymphs were more likely to develop a bullseye rash and therefore diagnosed with LD in comparison with those bitten by an adult tick. None of those bitten by adult ticks developed a bullseye rash.

The Bullseye is a poor indicator of LD.

Only 50% with LD got any kind of rash and only 9% developed a bullseye.

Two pills used at the time of tick bite by a nymph prevented people from getting the bullseye – so they were not diagnosed as having LD and were excluded from the study.

So, will 2 pills of doxy prevent Lyme?

No.

Controversies in Chronic LD

http://www.nursingcenter.com/journalarticle?Article_ID=3874121&Journal_ID=237151&Issue_ID=3874037

Journal of Infusion Nursing Volume 39, Number 6, Nov/Dec 2016

Elizabeth L. Maloney, MD

ABSTRACT
The Centers for Disease Control and Prevention estimates that more than 300, 000 new cases of Lyme disease occur each year in the United States and that 10% to 20% of these patients will remain symptomatic despite receiving appropriate antibiotictherapy. Many elements of the disease are poorly understood and have generated considerable controversy. This paper discusses the medical controversies related to posttreatment manifestations and their potential impact on infusion nurses.

An executive summary of the article

In an article to infusion nurses, Dr. Maloney points out that less than 20% of all EM rashes have the “classic” bullseye pattern. Infection often involves several tissue types or systems and there is a wide variety of nonspecific disease manifestations. Dissemination can happen quickly but signs may not appear for weeks, months, or even years, and it is not unusual for patients to initially present with Late-stage disease.

In other words, it is quite illogical to think you can quickly pin this thing down & tie a pink ribbon on it.

The article goes on to delineate the existing controversies in Chronic Lyme Disease.

Controversy #1 – Lack of universally understood terminology

Maloney states that initially the word “Chronic” was neutrally used to simply mean that the disease could be long-standing, but that this term over time was denoted by the Infectious Diseases Society of America (IDSA) to a negative connotation when they dismissed the very idea of chronic infection with Lyme Disease and came up with the term Post-Lyme disease syndrome (PLDS), also endorsed by the CDC. Maloney states that their assumption of PLDS lacks proof as there are no tests of cure for Lyme or biomarkers that can identify PLDS.

Controversy #2 – Validity of persistent manifestations being attributable to LD

The bulk of evidence supports the idea that persistent symptoms are related to an active infection or Lyme-induced immune dysregulation, yet again the IDSA and CDC discount this. Maloney sites study after study, particularly recent evidence clearly showing distinct differences in cerebral spinal fluid proteins of patients with chronic LD and those with chronic fatigue, and a longitudinal study of positive EM patients which found that only 1% developed fibromyalgia, which is lower than the general population.

Controversy #3 Significance of LD Persistence

Maloney states the evidence is clear: the physical, social, and economic costs of chronic LD is substantial and is a burden for the whole country. LD patients in study after study had significant physical impairments that interfered with functioning including abnormal sensory ability and motor deficits with pain levels matching post surgical patients, fatigue similar to MS patients, and physical functioning similar to patients with congestive heart failure. In one study, 39% spent at least $5,000 out of pocket for treatment and had to stop working, while another 28% reduced their hours at work.

Controversy #4 Testing in Chronic Lyme

Evidence shows that there are no tests to determine if a patient has an ongoing infection, yet some doctors use serology to decide if a person has chronic Lyme. Current testing DOES NOT identify the bacterium, but rather looks for antibodies to the bacterium. Elevated levels indicate exposure; however, levels in the body change over time. Positive serology in treated patients doesn’t necessarily mean they have an active infection just as negative results are not indicative of cure.

Controversy #5 Uncertain causation of Chronic Lyme

Several causes for chronic Lyme have been suggested but supporting evidence is lacking and include:
1) Other infections
2) Post infectious state
3) Permanent or temporary tissue damage
4) Secondary conditions triggered by initial infection and persisting despite Bb eradication
5) Immune dysfunction either to autoantibodies or unregulated inflammation                       6) Persistent Bb infection

Many doctors acknowledge all of these potential causes except persistent infection despite much evidence to the contrary including an NIH sponsored study demonstrating documented uninfected ticks becoming infected after feeding on a chronically infected patient who had been treated for LD over a year earlier. Also, evidence for 1 cause of persistence does not rule out all others as well as it may be numerous mechanisms working together.

Controversy #6 Antibiotic Usage

The CDC and IDSA propagate the idea that antibiotic treatment is risky and doesn’t help patients, while others disagree. According to Maloney the evidence supports the selective use of antibiotics for chronic Lyme. She also states that the trials by Klempner et al should not be used to prove that antibiotics are not helpful as the study was biased and of poor design. She also points out that findings demonstrating effective retreatment that improved patient outcomes as well as complete recovery in some, has received little notice and that most doctors are not going to even know about them. She also wisely mentions that immune modulators may be useful but persistent infection needs to be ruled out because lowering the immune response risks triggering an active infection.

Maloney clearly admonishes infusion nurses that the science of chronic Lyme is constantly changing but that many doctors have wrongly entrenched themselves in a biased opinion despite the reasoned opinions of colleagues and that due to this they will probably find themselves in the thick of the argument. She says nurses can and should influence treatment decisions by advocating for the patient and by staying abreast of current science and giving accurate information that offers options to create a dialog between care giver and care receiver.

Abstract

Background
Lyme neuroborreliosis (LNB) is one of the manifestations of Lyme disease. Although it is known that immune reaction of LNB patients is dominated by Th1 and Th2 responses and patients have elevated numbers of B cells in their cerebrospinal fluid (CSF), not all the cells involved in inflammation and cytokine secretion have been characterized. The current diagnostics of LNB is based on intrathecal production of antibodies. In recent years, the measurement of chemokine CXCL13 concentration from the CSF has been introduced as a new promising diagnostic tool for LNB to complement the antibody-based diagnostic methods. A few other cytokines have also been analyzed as possible diagnostic markers. However, multiplex analyses simultaneously evaluating the concentrations of a large number of different cytokines in the CSF of LNB patients have been lacking thus far. Extensive cytokine profiling CSF samples of LNB patients would also help in understanding the complex immunopathogenesis of LNB.

Methods
CSF samples were analyzed from 43 LNB patients, 19 controls, 18 tick-borne encephalitis patients, and 31 multiple sclerosis patients. In addition, CSF samples from 23 LNB patients obtained after the antibiotic treatment were examined. Altogether, the concentrations of 49 different cytokines were determined from all of the samples. The concentrations of 48 different cytokines were analyzed by magnetic bead suspension array using the Bio-Plex Pro Human Cytokine 21- and 27-plex panels, and the concentration of CXCL13 was analyzed by an ELISA based method.

Results
Distinct cytokine profiles which were able to distinguish LNB patients from controls, tick-borne encephalitis patients, multiple sclerosis patients, and LNB patients treated with antibiotics were identified. LNB patients had elevated concentrations of all major T helper cell type cytokines (Th1, Th2, Th9, Th17, and Treg) in their CSF.

Conclusions
Despite the great differences in the CSF cytokine profiles of different patient groups, CXCL13 still remained as the best marker for LNB. However, IL-1ra might also be helpful as a marker for the antibiotic treatment response. Concerning the immunopathogenesis, this is the first report suggesting the involvement of Th9 cells in the immune response of LNB.
