WASHINGTON — Advancing treatment for what has been variably called chronic Lyme and posttreatment Lyme disease (PTLD) is under the eyes of a National Academies of Science, Engineering, and Medicine (NASEM) committee of experts for the first time — a year after the NASEM shone a spotlight on the need to accelerate research on chronic illnesses that follow known or suspected infections.
The committee will not make recommendations on specific approaches to diagnosis and treatment when it issues a report in early 2025 but will instead present “consensus findings” on treatment for chronic illness associated with Lyme disease, including recommendations for advancing treatment.
It’s an area void of the US Food and Drug Administration–approved therapies, void of any consensus on the off-label use of medications, and without any current standard of care or proven mechanisms and pathophysiology, said John Aucott, MD, director of the Johns Hopkins Medicine Lyme Disease Clinical Research Center, Baltimore, one of the invited speakers at a public meeting held by the NASEM in Washington, DC.
“The best way to look at this illness is not from the silos of infectious disease or the silos of rheumatology; you have to look across disciplines,” Dr. Aucott, also associate professor of medicine in the Division of Rheumatology, told the committee. “The story doesn’t fit anything I trained for in my infectious disease fellowship. Even today, I’d posit that PTLD is like an island — it’s still not connected to a lot of the mainstream of medicine.”
Rhisa Parera, who wrote and directed a 2021 documentary, Your Labs Are Normal, was one of several invited speakers who amplified the patient voice. Starting around age 7, she had pain in her knees, spine, and hips and vivid nightmares. In high school, she developed gastrointestinal issues, and in college, she developed debilitating neurologic symptoms.
Depression was her eventual diagnosis after having seen “every specialist in the book,” she said. At age 29, she received a positive western blot test and a Lyme disease diagnosis, at which point “I was prescribed 4 weeks of doxycycline and left in the dark,” the 34-year-old Black patient told the committee. Her health improved only after she began working with an “LLMD,” or Lyme-literate medical doctor (a term used in the patient community), while she lived with her mother and did not work, she said.
“I don’t share my Lyme disease history with other doctors. It’s pointless when you have those who will laugh at you, say you’re fine if you were treated, or just deny the disease completely,” Ms. Parera said. “We need this to be taught in medical school. It’s a literal emergency.”
Incidence and Potential Mechanisms
Limited research has suggested that 10%-20% of patients with Lyme disease develop persistent symptoms after standard antibiotic treatment advised by the Infectious Diseases Society of America (IDSA), Dr. Aucott said. (On its web page on chronic symptoms, the Centers for Disease Control and Prevention presents a more conservative range of 5%-10%.)
