BACKGROUND: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED, APS1) is an autosomal recessive disease exceptionally common in Finland. Most patients have chronic oral candidiasis from early childhood and this infection has been shown to be carcinogenic. Hence, patients receive repeated treatment and prophylactic courses of antifungals throughout life. In Finland, 92 patients have been diagnosed with APECED and 66 of them are currently alive. Our aim was to study the effect of long-term azole treatment on the candidal colonization of APECED patients and the influence on antifungal susceptibilities. METHODS: We evaluated the culture reports from 1994 to 2004 of 56 APECED patients followed in Helsinki University Central Hospital. Candida albicans strains of all 11 patients initially reported resistant (n = 27) and 12 patients reported susceptible (n = 16) to fluconazole were re-analysed for their susceptibility to fluconazole. Antifungal usage was analysed up to 30 years back. RESULTS: A total of 162 fungal cultures had been performed. Of these, 75% had been reported positive for Candida and 63% for C. albicans. Eleven patients (31.4%) had been reported to harbour at least once a C. albicans strain resistant to fluconazole. Re-analysis of the stored C. albicans strains originally reported to be resistant to fluconazole revealed a mean MIC of 19.5 mg/L. CONCLUSIONS: Multiple courses (>6) of fluconazole annually and low dose prophylaxis are major risk factors for persistent colonization with C. albicans with decreased susceptibility in APECED patients.
