Men and women experience Lyme disease differently, according to a new study from Johns Hopkins Medicine, published February 7 in Clinical and Experimental Medicine. Researchers found distinct variations in how the illness manifests in early stages, impacting both reported symptoms, physical examination findings, and laboratory test results.
The study highlights a critical need to consider sex-specific differences when diagnosing and treating Lyme disease, a tick-borne illness caused by the bacterium Borrelia burgdorferi. Even as traditionally understood as presenting with a characteristic “bullseye” rash and flu-like symptoms, the research indicates this presentation isn’t uniform across genders.
The findings arrive as the Lyme and tickborne diseases field is experiencing increased research attention. Nicole Baumgarth, recently appointed as the inaugural director of the Johns Hopkins Lyme and Tickborne Diseases Institute at the Bloomberg School of Public Health, is expected to lead further investigations into the complexities of Lyme disease and related illnesses.
Researchers also noted that the presentation of Lyme disease can vary based on menopausal status in women. This adds another layer of complexity to diagnosis, as hormonal changes associated with menopause can potentially mimic or mask Lyme disease symptoms.
The study’s findings also underscore existing health inequities in Lyme disease diagnosis, and treatment. Recent research indicates that Black individuals are more likely to face delays or inaccuracies in receiving a Lyme disease diagnosis. These disparities, coupled with the newly identified sex-based differences, suggest a need for more inclusive and nuanced diagnostic approaches.
Ongoing research, including studies focused on long-haul Lyme disease, aims to better understand the chronic symptoms experienced by some patients after initial treatment. Johns Hopkins Medicine is actively involved in these efforts, seeking to identify the underlying mechanisms driving persistent illness and develop more effective therapies.
