Epidemiology of dermatomycoses in southwest Poland, years 2011–2016

Abstract

IntroductionSuperficial mycosis is one of the most common diseases worldwide, however its epidemiology is changing over time.AimTo present epidemiological data of the skin fungal infections diagnosed in the years 2011–2016 in Lower Silesia.Material and methodsA total of 11 004 patients with a clinically suspected superficial mycosis were investigated. Skin scrapings, nail clippings and plucked hair were examined with a direct microscopy, Wood’s lamp and culture. Particular species were identified via polymerase chain reaction (PCR) examination. The lesions suspected for pityriasis versicolor were screened for Malassezia with Wood’s lamp and direct microscopy.ResultsDermatomycosis was diagnosed in 1653 (15.00%) patients with 1795 fungi identified. 1858 specimens were indicative of fungal infection including dermatophytes, yeasts and moulds. Out of 924 cases of dermatophytic infections (51.48%), Trichophyton rubrum accounted for the majority (71.75%) and was followed by Trichophyton tonsurans (16.77%). Among the yeasts (716; 39.89%), Candida spp. was the most common agent identified (521; 67.66%). The sites affected most often were toenails (956; 51.45%) and fingernails (319; 17.17%). In paediatric population the most common diagnosis was tinea corporis (60, 41.10%).ConclusionsOur study revealed that toenail onychomycosis remains the most common superficial mycosis and T. rubrum is the most common pathogen. However, in a longer period of observation, a decrease in the number of tinea capitis cases and an increase in infections caused by T. tonsurans were noticed. Observed changes indicate the need for continuing studies to detect the upcoming epidemiological trends.

Analysis on the pathogenic fungi in patients with superficial mycosis in the Northeastern China during 10 years

“…The top three pathogenic fungi of superficial mycosis isolated in the 10 years from 2008 to 2018 were Trichophyton rubrum , Trichophyton mentagrophytes and Candida . The results were different from the previous research results in Jilin ( 17 ). However, Trichophyton rubrum is still the first pathogen species, and most studies in China and worldwide also show that Trichophyton rubrum is the primary pathogen of superficial mycosis ( 18-21 ).…”

Epidemiology of dermatophytoses in paediatric population in Southwestern Poland, 2011–2016

“…We also demonstrated that there are significant differences between children and adults. We compared our data with results from a survey conducted in our region in the general population in 2011–2016 [ 29 ]. T. rubrum was also the most prevalent causative agent detected in 71.75% of cases, followed by T. tonsurans observed in 16.77% of cases.…”

“…Furthermore, at this time, T rubrum gained the leading position among anthropophilic species with a share of 70%, followed by T interdigitale (0.6%–34%) and E floccosum (19%–15%). Recently, a single‐centre study on superficial mycoses in Lower Silesia (Poland) conducted between 2011 and 2016 showed that T rubrum represented 80.69% dermatophytes isolated from toenails and 72% isolated from feet, whereas the second was T tonsurans (14% and 22%, respectively) 10 . The global epidemiology of dermatophytosis was extensively reviewed by other authors 4,7,11 .…”
