Emerging trends in dermatophytosis among pediatric age group - A view from the south

Background: Dermatophytosis is a common dermatological condition in children. Recent trends indicate increasing occurrence of dermatophytic infection in the paediatric age group and with growing anti-fungal resistance; however, more studies describing clinic-epidemiological and mycological pattern in paediatric population are needed. Aims and Objectives: The present study was undertaken to assess the clinical pattern and mycological isolates from the lesions of dermatophytosis involving the glabrous skin and to assess the association of fixed dose combinations creams with clinical and mycological pattern of cutaneous dermatophytosis. Materials and Methods: Paediatric patients (ages 1 -14) with suspected tinea infections presenting in the Department of Dermatology at a tertiary care medical college hospital in South India for a duration of four months, in 2020, were included in this study. Samples were collected and tested for potassium hydroxide (KOH) positivity. Additionally, the scales were also sent for fungal culture. Results: Out of 45 patients, 29 (64.4%) were male and 16 (35.6%) were female. The groin was the most common site affected in 89.65% patients. Around 57% of the study participants (21/45) have used corticosteroid-containing creams. Out of the 45 study participants, KOH mount was positive in 39(86.7%). Fungal Culture revealed Trichophyton mentagrophytes (55.6%) as the most common species isolated. Conclusion: Our study illustrates a major epidemiological shift of dermatophytosis causing species from Trichophyton rubrum to Trichophyton mentagrophytes among paediatric patients akin to that observed in adults. It is also observed that there is an increase in an atypical presentation owing to topical steroid use. The present study provides evidence that a high index of suspicion in needed to effectively curb the rising incidence of dermatophytosis in paediatric patients.
