Medical Care
For decades, penicillins and tetracyclines have been the treatment of choice in relapsing fever. In vitro, Borrelia species are also susceptible to cephalosporins, macrolides, and chloramphenicol, although less data are available on these antibiotics.[14, 12] The efficacy of treatment can be demonstrated by noting clearance of spirochetes in the blood, usually occurring within 8 hours of administration of an effective antibiotic.[14, 28]
- In adults with louse-borne relapsing fever (LBRF), treatment consists of a single dose of tetracycline, doxycycline, or erythromycin. Treatment of tick-borne relapsing fever (TBRF) is the same as that for LBRF, except the treatment duration is 7-10 days.
- In adults, intravenous therapy with doxycycline, erythromycin, tetracycline, chloramphenicol, or procaine penicillin G should be used when oral therapy is not tolerated.[2]
- Intravenous chloramphenicol is administered at 500 mg once in LBRF and 500 mg every 6 hours in TBRF.[2] The oral preparation of chloramphenicol is unavailable in the United States.
- Procaine penicillin G[2] may be administered at a single dose of 600,000 IU in patients with LBRF or 600,000 IU daily in patients with TBRF.[2]
- In children younger than 8 years and in pregnant or nursing women, erythromycin is preferred.[2]
- Meningitis is treated with either intravenous penicillin or ceftriaxone.[4]
Consultations
- Consultation with an infectious disease specialist may be helpful.
- A critical care specialist and/or pulmonologist should be consulted for patients with relapsing fever who are severely ill.
