Research into the pathogenesis and treatment of chronic recurrent candidosis vaginalis did not come up with a clear answer of curing this phenomenon. In this investigation, data are presented of a therapy with a new antifungal agent, itraconazole. After a therapeutic treatment course, 17 patients received a prophylaxis for CRCV over 6 months. The treatment schedule for prophylaxis consisted of 4 capsules of 50 mg itraconazole on day 5 and 6 of the menstrual cycle. Eleven remained symptom-free in this period. Although there is no explanation for recurrence in most cases of CRCV, intermittent treatment schedules can be used to treat but not to cure these patients. Data of this investigation and data mentioned in the literature prove the necessity to discriminate between a sympatomtic and a mycological cure.
