Abstract

Background We describe 11 cases of refractory vulvovaginal yeast infections (RVVYI) treated using oral voriconazole with or without concomitant topical agents. Methods Retrospective case-note review of all women prescribed oral voriconazole to treat RVVYI in five Sexual Health Clinics from Jan 2010-March 2020. Demographic details, clinical features, diagnostic results and treatment outcomes were collected. Results 11 women with vulvovaginal symptoms for a median of 1 year were treated with voriconazole. RVVYI was diagnosed clinically and confirmed on microscopy and culture with speciation. 10/11 isolates were fluconazole resistant, 1 intermediately sensitive, 10/11 were either fully or intermediately sensitive to voriconazole. All had received prior fluconazole and clotrimazole and 10/11 had used at least 2-weeks of one or more second-line antifungals with non-clearance of the yeast. Oral voriconazole 400 mg BD day-1, then 200 mg BD 13-days was prescribed and 10/11 women completed the course. Concomitant topical treatment was used by 6/11. Liver and renal function were monitored at 0, 7, 14 days. One woman stopped voriconazole after 5-days due to perioral tingling. Other transient side-effects were nausea ( n = 2), photosensitivity, muscle aches, hair thinning (all n = 1), peripheral visual disturbance ( n = 2). 8/11 experienced both symptom reduction and yeast clearance. Two women had an initial partial response but experienced resolution of symptoms following a second course of voriconazole. Conclusions Our observational data adds to the limited evidence to support voriconazole treatment for RVVYI. A 2-week course of voriconazole was tolerated and completed by 10/11 women. Eight women, five using concomitant topical agents, achieved mycological cure.
