The importance of tumour necrosis factor-alpha (TNF-α) in the human immune response to Borrelia burgdorferi is uncertain. Murine models suggest a critical role, including spirochaete reactivation following TNF-α inhibition. Our case, combined with a review of the clinical and scientific literature, provides reassurance that TNF-α inhibition can be safely reinstituted after treatment of disseminated borreliosis with standard duration antimicrobial chemotherapy.
