Erythromycin and lymecycline treatment in chlamydia-positive and Chlamydia-negative non-gonococcal urethritis--a partner-controlled study

Abstract

A group of 213 men with non-gonococcal urethritis and their sexual partners were treated either with erythromycin stearate 500 mgx2 for 15 days or with lymecycline 300 mgx2 for 10 or 20 days. Chlamydia trachomatis was isolated from 40% of the men, from 26% of their female partners and from 56% of the partners of men with chlamydia-positive urethritis. One hundred and eighty-one men were available for evaluation of therapy. There were no significant differences between the treatment schedules. The cure rate was 86-90% in men with chlamydia-positive and 89-100% in men with chlamydia-negative urethritis. Four of the 17 chlamydia-positive females treated with erythromycin and 2 of the 20 chlamydia-positive females treated with lymecycline for 10 days still had chlamydia at re-examination.
