This pandemic has brought many different modalities in diagnostics, drug development and vaccines to the popular press. In the Tick-borne Disease (TBD) community, we have seen the issues that arise when the timely diagnosis and treatment of infectious disease are hampered by insensitive diagnostics and ineffective treatments.
It bears repeating however, that drugs that fight the infection in question (antibiotics, antiparasitics, or antivirals) are a large part of any eventual solution to an outbreak, especially in advance of a vaccine (see HIV). Antimicrobial therapeutics help keep the pathogen from replicating uncontrolled, allowing the complicated immune system processes to catch up to it, control it and then eradicate it.
One specific treatment modality is being widely discussed: monoclonal antibodies (mAbs). These are the drugs upon which the whole biotech industry and companies like Genentech, Biogen and Amgen were literally built. Six out of the top 10 drugs by sales are mAbs, mostly for oncology and autoimmune disease indications. However, mAbs have not been commonly used for infectious disease (with one major exception we’ll talk about later).
What are monoclonal antibodies? How do they work?
Antibodies are proteins made by the mammalian immune system. They are a workhorse of the acquired immune response and fight specific antigens, which can be anything from an invading pathogen to an aberrant cell or cytokine that needs destruction. Monoclonal antibodies as a drug class are also very specific and only bind to one antigen. They can bind to a single receptor on the outside of a cell, so that cell can’t receive or send out a message. Or the cell can be tagged so the immune system recognizes the cell as foreign and can destroy it. Binding only one target is important to reduce side effects caused by binding to multiple targets.
New Study Shows Less Than One-Third of Lyme Disease Test Results are Accurate for Patients with Lyme Rash
Journal of Clinical Microbiology Publishes Lyme Disease Biobank Data Describing Samples Available for Research on Tick-Borne Infections
Portola Valley, Calif., February 26, 2020—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the U.S., announces results published in the Journal of Clinical Microbiology, a journal of the American Society for Microbiology, that point to limitations of currently available diagnostic tests for early-stage Lyme disease and highlight the need for more research toward improved diagnostics and treatments. Among the findings, the Centers for Disease Control’s Standard Two-tier Testing Algorithm (STTTA) for Lyme disease failed to accurately diagnose 71% of blood samples from individuals presenting with a Lyme rash, also known as an erythema migrans, greater than 5 cm in endemic areas. These samples are part of the Lyme Disease Biobank (LDB), which was founded to catalyze new research in the understanding, diagnosis and treatment of Lyme disease and other tick-borne infections. Samples are available for research use through an application process to scientists who already work in tick-borne infections, as well as those new to the field.
Seven Herbal Medicines Are Capable of Killing Lyme Disease Bacteria, According to New Lab Study
Research Supported by Bay Area Lyme Foundation Evaluates Anti-microbial Effects of 14 Natural Products Compared to Antibiotics Used to Treat Lyme Disease
Marin, CA, February 21, 2020—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the U.S., today announced the publication of new data finding that seven herbal medicines are highly active in test tubes against B. burgdorferi, the bacteria that causes Lyme disease, compared to the control antibiotics, doxycycline and cefuroxime. Published in the journal Frontiers in Medicine, the laboratory study was funded by the Bay Area Lyme Foundation and supported in part by The Steven & Alexandra Cohen Foundation. The study was a collaboration between researchers at Johns Hopkins Bloomberg School of Public Health and colleagues at the California Center for Functional Medicine and FOCUS Health Group, Naturopathic.
“Since traditional antibiotic approaches fail to resolve symptoms in up to 25% of patients treated for Lyme disease and many suffer disabling effects of the disease, there is a need for novel treatment proven effective against B. burgdorferi,” said the paper’s co-author Sunjya K. Schweig, MD, CEO and co-director, California Center for Functional Medicine and Scientific Advisory Board Member, Bay Area Lyme Foundation. “Because patients are currently turning to herbal remedies to fill the treatment gaps left by antibiotics, this research is a critical step in helping clinicians, as well as patients, understand which ones may offer the most potential benefit.”

What follows is an article written by a guest contributor and practicing care provider who shares that view and her personal and professional experience in hopes that it can help others with their healing journeys.
First West Coast CME Program on Tick-borne Disease Provides New Data, Insights from Researchers
Stanford University School of Medicine and Massachusetts General Hospital host clinical and research forum funded by Bay Area Lyme Foundation
Silicon Valley, CA, September 3, 2019—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the U.S., today highlights the first tick-borne disease CME program on the West Coast, Emerging Research, Diagnosis and Treatment of Lyme Disease and Tick-Borne Illness. The conference was hosted by two major academic institutions representing the East and West Coasts of the U.S., Stanford University School of Medicine and Massachusetts General Hospital, and included presentations related to the magnitude of tick-borne disease in California, emerging diagnostic technologies, potential future treatment options, and epidemiological statistics enabled by Lyme disease biobanks.
“There is a lack of understanding about the variety and severity of tick-borne illnesses such as Lyme disease on the west coast” said Charles Chiu, MD, PhD, professor of laboratory medicine and infectious diseases at UCSF, associate director of the UCSF Clinical Microbiology Laboratory, and Bay Area Lyme Foundation Scientific Advisory Board member. “This was a great opportunity to share the latest findings and ongoing research on the topic, so that physicians and other medical professionals can more quickly and accurately diagnose and treat their patients.”
Bay Area Lyme Foundation Tick Testing Program Adds Bartonella Pathogen Assay
Nationwide Free Tick Testing Initiative Will Inform Citizen-Science Studies to Better Understand the Spread of Ticks Carrying Diseases Throughout U.S.
Silicon Valley, CA, July 11, 2019 — Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the U.S., today announced the relaunch of its nationwide free tick testing program, which will include an assay for Bartonella, a disease-causing pathogen carried by ticks. Based on the success of the Free Tick Testing Citizen Science program, Bay Area Lyme Foundation has significantly increased funding for the 2019 nationwide collection effort, adding an automated submission process and increased research support. Researchers anticipate this citizen- science program will enable the organization to unearth further discoveries.
Results of the first citizen-scientist study were published in the peer-review journals PLOS ONE in 2018, and International Journal of Health Geographics in 2019. The study, which evaluated the prevalence of disease-carrying ticks throughout the United States, and included a massive sample of more than 16,000 ticks collected from 49 U.S. states and Puerto Rico, led to the discovery of ticks capable of carrying Lyme and other tick-borne diseases in 83 counties, in 24 states, where these ticks had not been previously recorded. The program received a six-fold increase in tick submissions over initial estimates, representing unprecedented national coordination of a ‘citizen science’ effort and diagnostic investigation.
If your trail is overgrown and thick with tall grasses (and most are thanks to a very wet Spring this year) … then you need to be aware of TICK HITCHHIKERS…
Unlike their highway counterpart these tick free riders don’t ask, they just grab on as you, your pet (or your horse) pass by. They perch quietly on the grasses and weeds that line your trail or backyard patiently waiting for their next unsuspecting host (and likely meal).
All too easily, you end up taking home a few uninvited guests and if not careful about checking and removing these pests when you return home, you could also end up inviting possible infection into your home.
Ticks carry Lyme disease and many other related infections that can cause debilitating and lasting symptoms. Tick incidence is on the rise almost everywhere, in part due to climate change and wetter, milder winters. If you enjoy the outdoors, you need to be aware of these itinerant nuisances and you need to take precautions to stay safe…
