Factors influencing epidemiology of dermatomycoses at Gdansk, Poland and Grodno, Belarus.

Abstract

IntroductionAn increase in numbers of cutaneous fungal infections is being observed around the world. Dermatomycoses occur in every age group and can significantly decrease quality of life. Examining the prevalence and epidemiological trends of cutaneous fungal infections is necessary for developing new effective preventive, diagnostic and therapeutic methods. Many factors can influence the growth and patterns of global spread of the different species of fungi.AimTo investigate the differences between the prevalence of dermatophytes and cutaneous fungal infections observed at two mycological laboratories and their plausible causes.Material and methodsMycological examination was performed in 7324 patients in Gdansk, Poland and in 4729 patients in Grodno, Belarus who exhibited clinical signs and symptoms of cutaneous fungal infections. Direct preparations was made in 20% KOH with 40% DMSO. Additionally cultures were prepared on modified Sabouraud dextrose agar.ResultsDermatophytes were cultured in 642 (53.58%) cases in Gdansk. The most common species of dermatophytes were Trichophyton rubrum (306 cases), Trichophyton mentagrophytes var. granulosum (193 cases) and Microsporum canis (127 cases). Yeasts were isolated in 531 (44.40%) cases out of which Candida albicans was the most frequently identified in 323 cases. Similarly, dermatophytes were the most common in 1158 (68.72%) cases in Grodno. Candida were isolated in 527 (31.28%) cases. Analysing the localization of dermatomycoses onychomycosis was observed in majority of the infected patients in Gdansk. In Grodno the most common location of superficial cutaneous infection was tinea corporis In the Gdansk region dermatomycoses were observed in 688 female patients and in 508 male patients. In Grodno the prevalence is inverted with the majority of cases observed in 921 males and 764 females.ConclusionsThe prevalence of superficial fungal infections is higher in Grodno, Belarus when compared to Gdansk, Poland. Similarly, dermatophytes were most commonly observed in both Laboratories.
