Abstract

Pemphigus vulgaris is an autoimmune disease that mostly affects the mucosa and oral cavity. Candida species can invade the mucosal lesions of these patients and cause diseases. The aim of this study was to identify the fungal agents isolated from mucosal lesions and evaluate antifungal activity profile against the isolates. A total of 25 patients with pemphigus vulgaris with active oral lesions and 25 healthy people serving as a control group were included in this study. Identification of the fungal isolates was performed based on conventional methods and DNA sequence analysis of the internal transcribed spacer (ITS) rDNA gene region. The sequence results were deposited in the NCBI database using the Basic Local Alignment Search Tool. Antifungal activity of fluconazole, itraconazole, ketoconazole, posaconazole, econazole, and amphotericin B against the isolates were evaluated based on the CLSI M-44 A protocol.  Oral candidiasis was detected in 20% of the patients. Candida species isolated from oral lesions of patients with pemphigus were identified as Candida albicans 22/25, Candida glabrata 2/25, and Candida dubliniensis 1/25. All of the isolates were sensitive to amphotericin and econazole, 96% to fluconazole and posaconazole, and 92% to ketoconazole and itraconazole. One patient showed a profile resistant to fluconazole, posaconazole, and ketoconazole, simultaneously. Ninety six percent of control group isolates were sensitive to six antifungals. Candida albicans was the most prevalent species isolated from oral lesions of patients with pemphigus vulgaris and the control group. Amphotericin B and econazole were the most effective antifungals against the isolates.
