The present study was undertaken to evaluate the efficacy of clinical andmicrobiological investigations available in limited resource settings for an effectivediagnosis of vaginal infections/abnormal vaginal microbiota among pregnant women.As an outcome of the study we intended to find the association of various vaginalinfections during pregnancy with preterm delivery. Pregnant women presenting forroutine antenatal care at an antenatal clinic in south India were enrolled in thestudy. Each participant underwent clinical and microbiological examinations for thediagnosis of vaginal infections such as bacterial vaginosis (BV), vulvovaginal can-didiasis (VVC) and trichomoniasis. In addition, Gram’s stained high-vaginal smearswere evaluated for the presence of partial BV and vaginitis. Diagnostic accuracies ofclinical diagnosis for the aforementioned infections was determined in comparison with gold standard microbiological diagnosis. Proportion of women with vulvovaginal infections were estimated using descriptive statistics and incidence risk ratio for preterm delivery with each form of the infection was estimated using univariate analysis. A total of 790 pregnant women were recruited in the study. Positive predictive values of clinical diagnosis for BV, VVC and Trichomoniasis in comparison with reference method were 72.7, 33.5 and 37.6% respectively. Partial BV (3.2%) and vaginitis due to mixed bacterial etiology (9.4%) were per exclusionem diagnosed using the microbiological smear examination. Microbiological diagnosis of BV and vaginitis were found to have a statistically significant association with preterm delivery. Effective diagnosis of vaginal infections/abnormal vaginal microbiota associated with preterm delivery can be achieved by the adjunct of microbiological smear examination of the vaginal smears to the clinical examination in limited resource settings.
