Non-response to fluconazole maintenance treatment (ReCiDiF regimen) for recurrent vulvovaginal candidosis is not related to impaired glucose metabolism.

ABSTRACT

Is non-response to maintenance treatment for recurrent vulvovaginal candidosis (RCVV) related to the impaired glucose metabolism? In the ReCiDiF trial, women with RCVV were given a degressive regimen with fluconazole according to their clinical, microscopic and mycologic response. Data obtained from optimal, suboptimal and non-reponding patients were used for secondary analysis of medical history, physical status and family history for potential glucose impairment. Results were presented in means and percentages. Pearson chi-square, Fisher exact, Mann-Whitney U, Kruskal-Wallis and Spearman's correlation coefficient was calculated. P<.05 were interpreted as statistically significant. Sociodemographic characteristics and family and personal history of diabetes were not different between optimal, suboptimal and non-responders. The average HbA1c concentration was 5.1±0.3% in optimal, 5.0±0.4% in sub-optimal, and 5.1±0.3% in non-responding patients (P=1.0). There are no statistical differences between optimal, sub-optimal and non-respondents to treatment in all deciles of HbA1c among patients with recurrent candidosis (P=1.0). There was no difference among groups in fasting glucose concentration, nor after 30 min, 60 min or 120 min during the oral glucose tolerance test (OGTT) (P=.6). Area under the OGTT curve did not differ within groups (P=.8), nor was the deviation from the normal cut-off value any different (P=.8). Glucose concentration in vaginal rinsing fluid showed no correlation with responsiveness to treatment (P=.7). Glucose metabolism, BMI, personal or family history of diabetes are not related to non-response to maintenance treatment with fluconazole for patients with RVVC.
