Bay Area Lyme Happenings Series

UCSF has joined the Cohen Foundation’s nationwide Lyme Clinical Trials Network (CTN) for Lyme and tick-borne diseases. The new Lyme Clinical Trials Center (CTC) at UCSF was funded by a $1m grant from Bay Area Lyme Foundation and is led by Charles Chiu, MD, PhD, and Felicia Chow, MD, as co-principal investigators. As the West Coast ‘node’ in the network, UCSF’s new Lyme Clinical Trials Center will focus on interventional trials and diagnostic studies to improve diagnosis and treatment of Lyme disease.

In this presentation to patients with Lyme disease in Marin County just north of San Francisco, Dr. Chow explains how the CTC allows for a more diverse patient population to participate in Lyme clinical trials, which is critical for developing therapies that can help a wider range of patients. UCSF’s involvement also aims to help Bay Area Lyme raise awareness that Lyme disease is prevalent year-round in almost all California counties.

Dr. Chow discusses an upcoming trial at UCSF that will evaluate the use of transcranial direct current stimulation (tDCS) to improve cognitive symptoms in patients with chronic Lyme disease. Additionally, UCSF researchers are exploring the use of metagenomic sequencing and machine learning to develop more accurate diagnostic tests for Lyme and other tick-borne infections.

“I hope that through these clinical trials, we’ll be able to identify therapies that are helpful to patients and that, as a result, have an impact on clinically meaningful outcomes—from day-to-day function, quality of life, and all of those important measures that indicate that a treatment is successful.”

FOR IMMEDIATE RELEASE

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.
