Summary. A 29‐year‐old female suffering from full‐blown AIDS received fluconazole 400 mg day ‐1 for a long period for treatment of oral candidosis, pseudomembranous type. She had previously received this drug repeatedly for the same reason, yet manifest disease persisted. She was therefore put on parenteral amphotericin B, which led to clinical, but not mycological, cure in the short term. IC 30 testing revealed a minimum inhibitory concentration (MIC) > 128 μg ml ‐1 for fluconazole. The isolate, however, was susceptible in vitro to ketoconazole, itraconazole and amphotericin B. The same antimicrobial susceptibility pattern was found with a second isolate obtained later. Resistance to fluconazole might become a major problem in HIV‐infected patients receiving this drug for long periods. Zusammenfassung. Eine 29‐jährige manifest an AIDS erkrankte Patientin erhielt 400 mg Fluconazol per os über längere Zeit zur Behandlung einer oralen Candidose vom pseudomembranösen Typ. Eine daraufhin erfolgte Umstellung der Therapie auf Amphotericin B parenteral führte zur klinischen, nicht aber zur mykologischen Heilung in der kurzen Frist. Die IC 30 ‐Testung des Candida albicans ‐Isolates erbrachte eine minimale Hemmkonzentration (MHK) für Fluconazol von > 128 μg ml ‐1. Das Isolat war demgegenüber in vitro empfindlich gegenüber Ketoconazol, Itraconazol und Amphotericin B. Korrespondierende Empfindlichkeit wies auch ein konsekutives Isolat aus. Fluconazol‐Resistenz könnte ein größeres Problem bei HIV‐infizierten Patienten werden, die dieses Medikament über längere Zeit erhalten.
