Treatment of erythema chronicum migrans of Lyme disease
1Department of Dermatology, New York University School of Medicine, New York 10016.
Abstract:
Between June 1981 and July 1987 the efficacy of antibiotic treatment of 215 patients with erythema chronicum migrans of Lyme disease was evaluated in terms of the necessity for retreatment and the prevention of the late manifestations of Lyme disease. The principal antibiotics utilized to treat 161 patients through 1986 were varying doses of tetracycline, or penicillin alone or in combination with probenecid. Two of 80 patients with a minor form of the illness and 17 of 81 patients with a major form of the illness required retreatment. There were four patients who did not respond to retreatment with their original medication. A 15- to 30-day course of amoxicillin (500 mg q.i.d.) and probenecid (500 mg q.i.d.) or doxycycline (100 mg t.i.d.), and on three occasions ceftriaxone (2-4 g/day i.v.), were used to treat 54 patients in 1987. Although it is too early to judge the efficacy of treatment in these patients, increases in the incidence of Herxheimer reactions and drug eruptions were observed. Strict compliance with treatment protocols and the possibility of reactions to medications should be thoroughly discussed with patients.
Insights
Antibiotic treatment for Lyme disease (erythema chronicum migrans) showed varying efficacy. While initial treatments were often successful, some patients with severe Lyme disease required retreatment, and new antibiotic regimens in 1987 led to observed adverse reactions.
Area of Science:
- Infectious Diseases
- Dermatology
- Pharmacology
Background:
- Lyme disease, characterized by erythema chronicum migrans, is a significant public health concern.
- Effective antibiotic therapy is crucial for managing Lyme disease and preventing its late-stage manifestations.
- Previous treatment protocols involved tetracycline, penicillin, and probenecid.
Purpose of the Study:
- To evaluate the efficacy of antibiotic treatment for erythema chronicum migrans (ECM) in Lyme disease.
- To assess the need for retreatment in patients with ECM.
- To determine the effectiveness of antibiotic regimens in preventing late manifestations of Lyme disease.
Main Methods:
- Retrospective analysis of 215 patients treated between June 1981 and July 1987.
- Evaluation of treatment efficacy based on retreatment necessity and prevention of late Lyme disease symptoms.
- Comparison of outcomes for patients treated with tetracycline, penicillin/probenecid, amoxicillin, doxycycline, and ceftriaxone.
Main Results:
- 19 out of 161 patients (11.8%) required retreatment for Lyme disease.
- Patients with major ECM forms had a higher retreatment rate (17/81) compared to minor forms (2/80).
- Newer antibiotic regimens (amoxicillin, doxycycline, ceftriaxone) in 1987 showed increased Herxheimer reactions and drug eruptions.
Conclusions:
- Antibiotic treatment for ECM is generally effective, but retreatment may be necessary, particularly in severe cases.
- Emerging antibiotic therapies require careful monitoring for adverse effects.
- Patient education on treatment adherence and potential medication reactions is essential.
