 New Study Reveals Potential Treatment for Neurologic Lyme Disease

Blocking certain fibroblast growth factor receptors is shown to be effective in reducing inflammation and cell death caused by neurologic Lyme infection in laboratory studies

PORTOLA VALLEY, Calif. April 18, 2024—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, recently announced the publication of a laboratory study showing that fibroblast growth factor receptor (FGFR) inhibitors may be appropriate as an anti-inflammatory supplementary treatment for neurologic Lyme disease, for which there are no universally effective treatments. Published in the peer-reviewed journal Frontiers in Immunology, this study shows FGFRs are activated in response to both live and non-viable Lyme bacteria in preclinical brain tissue models. Further, inhibition of FGFR1, FGFR2, and FGFR3 may help mitigate the neuroinflammatory and neuropathogenic effects of infection by the bacteria that causes Lyme disease, Borrelia burgdorferi.  

“Our research shows a potential connection between neurological Lyme disease and several other neurological conditions, and this common pathway may explain why Lyme can be confused with many other conditions. Increasing our knowledge of FGFRs and their effect on the brain will help us understand the common mechanisms that may underlie Lyme disease and other neurological diseases,” said Geetha Parthasarathy, PhD, assistant professor at Tulane National Primate Research Center, Tulane School of Medicine, and a Bay Area Lyme Foundation 2019 Emerging Leader Award winner. “This data shows that FGFRs can be novel targets of anti-inflammatory therapeutics in Lyme patients with persistent neuroinflammation.”

“Our findings from this and our previous studies also offer important insight that may help to explain why some patients still experience chronic neurological symptoms even after a short course of antibiotics,” added Dr. Parthasarathy.

The Long and Winding Road: The Story of Bay Area Lyme’s Multi-Year Quest to Identify Treatments for Lyme Patients

West Coast Clinical Trial Story

BAL Leading the Way Series

 

“The opening of a network of Lyme disease clinics is the culmination of many years of tireless work and the vision of a small group of determined women over 10 years ago. We are extremely optimistic that the Lyme Clinical Trials Network will accelerate the development of new treatments for patients with post-treatment and persistent Lyme disease.”

—Linda Giampa, Executive Director, Bay Area Lyme Foundation

 

When Bay Area Lyme Foundation (BAL) was formed a decade ago, its mission was clear: to make Lyme disease easy to diagnose and simple to cure. “And that’s still our goal,” emphasizes BAL co-founder Bonnie Crater, as she reflects on the last 10 years. However, appreciating the magnitude of the Foundation’s audacious mission requires an understanding of two complex—yet inextricably linked—medical domains: the world of diagnostics, and the world of therapeutics.

The ‘Holy Grail’ for Lyme disease is an accurate diagnostic test—or better yet a suite of specifically designed tests for the different stages of acute and persistent Lyme disease. Although great strides are being made in understanding the infection and the disease’s progression, the ‘silver bullet’ of accurate diagnostic tests continues to elude us. The current diagnostics for acute Lyme (a two-step process with an ELISA either followed by a Western blot or another ELISA) are fraught with problems. These tests may miss up to 70% of acute Lyme cases or deliver false negative results. They are unreliable for detecting acute Lyme and are ineffective indicators for anyone with a persistent/chronic tick-borne infection. (Watch or listen to our Ticktective with Brandon Jutras, PhD, to learn why the current direct detection tests for Lyme are so inaccurate.)

Add to this the fact that FDA-approved therapeutics—or ‘cures’—have not evolved much in 10 years either and foment controversy. A quick internet search on ‘How to treat Lyme disease’ will offer information from the IDSA (Infectious Diseases Society of America) stating that a 10-14-day course of oral antibiotics, such as amoxicillin or doxycycline, will do the job for someone with an EM (Erythema migrans) rash who has early/acute Lyme. But anyone who has had Lyme disease, been treated, and then experienced a continuation of symptoms knows that this recommended course of intervention often fails to clear the infection, leaving some persistent Lyme patients in limbo, and health care providers without an approved treatment protocol. Simply put, this is the continuing underlying treacherous terrain of Lyme, throwing up challenges in both diagnostics and therapeutics.
