Safety and Clinical and Microbiological Efficacy of the Combination of Fluconazole and Secnidazole for the Treatment of Symptomatic Vaginal Discharge

Overview

Genital tract infections (GTIs) have increased in the past decade and there is an association between sexually transmitted infections (STIs) and other infections like bacterial vaginosis (BV), with the HIV transmission. BV and Candida are the most common causes of vaginal infections in symptomatic women, the prevalence of BV being 22-50% and the prevalence of Candida 17-39%. In an effort to reduce the transmission of GTIs, the World Health Organization (WHO) proposed a syndromic diagnostic approach as a low cost alternative in places with no access to laboratory diagnostic tests. Justification. In patients with syndrome of vaginal discharge, an effective treatment against Candida albicans, Trichomonas vaginalis, and bacterial vaginosis is adviced, therefore, for syndromic management of symptomatic vaginal discharge the combination of fluconazole and secnidazole could be used. No studies evaluating this combination were found in the literature reviewed. Objectives: To describe the safety and the clinical and microbiological efficacy of a single oral dose of a combined treatment with secnidazole + fluconazole for the syndromic management of symptomatic vaginal discharge. Methods: Design: open label, uncontrolled clinical trial to estimate clinical efficacy and safety of the combination of fluconazole and secnidazole for the treatment of symptomatic vaginal discharge. The participants will be sexually active women with lower genital tract symptoms (leukorrhea, itching, burning, pain, foul-smelling vaginal discharge, or urethral symptoms) compatible with symptomatic vaginal discharge syndrome. The study will be conducted in an outpatient service of a hospital in Bogota, Colombia. Given the descriptive character of the study, no a priori hypothesis is considered. A consecutive convenience sample size of 100 symptomatic patients is calculated. The statistical analysis will be performed with STATA 11.0 software (College Station, Texas, USA). Simple and relative frequencies and measures of central tendency and dispersion appropriate for the distribution of the variables will be calculated. The study has been submitted and approved by the Ethics Committee of the Faculty of Medicine of the National University of Colombia and the Institutional Review Board of the participating institution. All women must sign a written informed consent form agreeing to voluntarily participate in the study.
