ABSTRACT

Background: Vulvovaginitis (vv) is a frequent inflammation of the vulva and vagina caused in 40% to 50% by opportunistic yeast of the gender Candida sp. Vulvovaginal Candidiasis (vvc) is caused in 85%–95% by Candida Albicans, and in lower percentages by C. Glabrata (5–15%), C. Tropicalis, C. Pseudotropicales and C. Kruzei. Currently an increase in non-albicans species has been reported.
Objective: To obtain the frequency of Candida sp in vaginal samples studied in a laboratory of clinical pathology in a General Hospital in Mexico City.
Material and Methods: We reviewed 1117 reports of vaginal samples from January to June 2005, from the laboratory of clinical pathology at the Dr. Manuel Gea Gonzalez General Hospital in Mexico City. We included all the reports, except the samples that could not be microbiologically assessed and the ones reported as contaminated.
Results: We found Candida sp in 134/1177 (11%) andC. Albicans in 11/134 (8%). During the sexual active life (16 to 45 years of age) the frequency was higher than 78%. The average monthly frequency was 1.9%, in pregnancy 22% and just 10% in vulvovaginitis (vv). Most of the studies (78%) came from the Gynecology and Obstetric departments.
Conclusions: vvc had a low frequency (11%), and the predisposing factors took their toll. The highest frequency was related to the years of active sexual life (78%) and a high frequency was also found during pregnancy (32%) and in young girls (6%) when associated to sexual abuse. In our small and highly selective group, the low frequency of Candida sp and C. Albicans in vaginal samples leads us to conclusions related only to the limitation in the reception of the patients, technical availability and previous empirical treatments. The use of chromogenic methods is desirable in order to identify more species of Candida and to be able to apply sensitivity tests.
