Abstract

AIM: The potential role of superantigens derived from microbial agents could be considered in the pathogenesis of psoriasis, but the association between Candida albicans and psoriasis severity is still controversial. The present study was designed to compare the prevalence of oral candidiasis in a group of psoriatic patients and healthy patients, and its correlation with psoriasis severity. METHODS: Seventy psoriatic patients with no history of systemic treatment and 70 closely-matched control patients underwent oral examination. Scraping of oral mucosa to detect Candida species was done using a sterile cytobrush. RESULTS: Candida was detected in the oral cavity of 20% of patients with psoriasis and 2.8% of control cases (P = .002), but none had clinical features of oral candidiasis. Candida albicans was the only species isolated from the oral cavity of both groups. No correlation was found between sex, age, phototherapy, and presence of oral candidiasis. There was a positive correlation between psoriasis severity and colony count (P < .001). CONCLUSIONS: The prevalence of oral candidiasis is higher in psoriatic patients and is associated with disease severity. It is not exactly clear whether oral candidiasis can aggravate psoriasis or if psoriasis can predispose patients to oral candidiasis. © 2018 John Wiley & Sons Australia, Ltd.
