Roxithromycin compared to doxycycline in the treatment of genital chlamydial infection and non-specific urethritis.

A single-blind randomized follow-up study was conducted to evaluate the efficacy and tolerance of roxithromycin 300 mg once a day compared to doxycycline 200 mg day 1 and 100 mg day 2-10 in the treatment of genital chlamydial infection in men and women and non-specific urethritis (NSU) in men. A total of 211 patients (200 men and 11 women) between 18 and 46 years were enrolled. The women were excluded from the efficacy analysis because of the low number, but were included in the tolerance analysis. The clinical (clearance of polymorphonuclear leucocytes in urethral smears) and bacteriological response was evaluated one and 11 days after the treatment. Of 113 included men with chlamydial infection, 105 (93%) and 96 (85%) were evaluable on respective follow-up visits and of 87 included men with NSU, 74 (85%) and 64 (74%) were evaluable one and 11 days after treatment, respectively. The bacteriological eradication rate immediately after the treatment in chlamydia positive patients was 92.7% and 100% for roxithromycin and doxycycline, respectively, and 91.8% and 100% at follow-up. The clinical cure rate of all evaluable patients was 83.1% and 80.7% for roxithromycin and doxycycline, respectively, one day after the treatment and 80.5% and 85.3% for the two drugs, respectively, 11 days after treatment. None of these observed differences was statistically significant. The diagnosis did not influence the clinical response rate with either drug. Probable and possible drug-related side-effects were more common after doxycycline than after roxithromycin, 35% and 19% respectively (P = 0.0032).(ABSTRACT TRUNCATED AT 250 WORDS)

Endemic versus non-endemic gonorrhoea in Stockholm: results of contact tracing.

The aim of the present study was to characterize endemic versus non-endemic gonorrhoea to identify risk groups for transmission and to evaluate the effects of intensified contact tracing performed by specially trained social workers at venereal clinics. A total of 671 gonorrhoea patients (283 women and 388 men) comprised the study group. Seventy percent of the women and 48% of the men had an endemic infection (P < 0.001). Men without a steady partner had an increased risk of non-endemic infection. A decrease from 75% to 40% was noted in the proportion of endemic infection in Stockholm from the first quarter of the study period (2 years) to the last. Contact tracing resulted in 1.2 identified partners per patient. A total of 736 partners were examined either as a result of contact tracing efforts or because they had sought medical care on their own prior to intervention. Forty-seven percent of these partners were infected, 44% were not infected and 9% were examined outside the study with results unknown to us. The partner notification efforts yielded 161 new untreated cases. Contact tracing of women generated one new case per 4.0 interviewed women and contact tracing of men one new case per 4.3 interviewed men. Interviewing index patients with endemic infection yielded the highest number of new cases. Forty-three percent of the patients were infected outside Stockholm but only a smaller part of these patients spread their infection further into the community.(ABSTRACT TRUNCATED AT 250 WORDS)

Magic Lite Chlamydia immunoassay in urogenital samples and urine versus chlamydial culture.

Magic Lite Chlamydia assay (commercial test kit for the identification of Chlamydia trachomatis) was evaluated on urogenital samples and urine with chlamydial culture as the reference method. The sediment of the transportation buffer of specimens which were Magic Lite positive but culture negative or toxic was investigated for elementary bodies with fluorescein-labelled anti-chlamydial antibodies. The prevalence of chlamydial infection among the 577 men investigated was 13.7% as estimated by culture and direct immunofluorescence and 6.4% among the 173 women. In order to improve the sensitivity a cut-off value below that recommended by the manufacturer was used. The sensitivity of Magic Lite in male urethral specimens was then 60.8% and that in female urethral/cervical specimens 90.9%. The specificity was 99.6% and 100%, respectively. In urine specimens the sensitivity of Magic Lite was 63.3% (men) and 63.6% (women). The specificity was 99.4% and 100%, respectively. The sensitivity of Magic Lite on male urethral specimens was related to the number of inclusion bodies per well in culture and it was higher among men attending with clinical findings of urethritis (69%) than among asymptomatic men sampled as a screening procedure (36%) (P < 0.05). Corresponding differences between the sexes and between those with and without symptoms were not noted for Magic Lite applied on urine samples.
