Abstract
The purpose of this study is to explore whether a correlation exists between the bacterial load of Borrelia persica in tick-borne relapsing fever (TBRF), established by quantitative real-time PCR, and the development of Jarisch-Herxheimer reaction (JHR) after the initiation of antibiotic treatment. Forty-two blood samples were included in our study. The mean bacterial load, as established by real-time PCR, in patients who developed JHR was significantly greater than in those patients who did not develop JHR (443,293 copies vs. 140,598, p = 0.035). Accordingly, real-time PCR may assist clinicians in identifying patients at higher risk of JHR.
