[Clinical and demographic profile of patients with gyneco-obstetric disease colonized by Streptococcus agalactiae].

Objective: To describe demographics and clinical features in women with vaginal colonization with Streptococcus agalactiae attended in a gyneco-obstetric hospital.

Methods: Descriptive study of 118 women with isolation of Streptococcus agalactiae in cervical swab during January 1992 to December 1998. Major patient features were obtained in retrospective revising their chart and were classified in demographic, gyneco-obstetrical and clinical characteristics. Statistical analyses were performed with descriptive statistics using central tendency measurements and dispersion, frequencies, rates and proportions with all different variables.

Results: Mean age was 31 +/- 11 years; 44 (37.3%) received attention because of sterility, 37 (31.4%) were pregnant, 26 (22%) had any other gynecological disease and, 11 (9.3%) were in a group of high pregestational risk. One hundred eleven (94.1%) were sexually active, starting at a mean age of 20.9 +/- 4.3. GBS was the only microorganism isolated in 70 patients (59.3%). A concomitant cervicovaginal infection was identified in 22 (18.6%) patients. A sexual transmitted disease was present in 25 (21.2%) patients, with isolation of human papilomavirus (HPV), M. hominis, C. trachomatis y T. vaginalis. Fifty-five patients had a concomitant illness: 24 with endocrine disease, 12 cardiovascular pathology and 10 with oncologic disease.

Conclusions: Vaginal colonization of mexican women by GBS is low. However, clinical and demographics characteristics are required to identify these women easily, because of the importance of maternal and infant infection by this organism.
