Exploring the clinical features and risk factors for children tinea capitis complicated with allergic diseases.

Abstract

Tinea capitis, atopic dermatitis and allergic rhinitis are the most common disorders endured by prepubescent children. Dermatophyte infections have been linked to allergic disorders, such as increased sensitivity to dermatophytes in patients with atopic dermatitis. To explore the correlation between tinea capitis and allergic diseases in children and to analyse their risk factors. This study monitored epidemiological changes in childhood tinea capitis and risk factors for whom with allergic disease in a single centre in three consecutive five-year intervals by reviewing clinical data and multivariate logistic data analysis. Between 2007 and 2022, there were 127 children patients with tinea capitis, the mean age was 4.83 years, and the male-to-female ratio was 1.76:1. Zoophilic Microsporum canis and Trichophyton mentagrophytes were the most prevalent pathogens, and the proportions remained relatively constant every 5 years. There were 34 (26.8%) children with tinea capitis complicated with allergic disease, among them 14 children with atopic dermatitis/eczema, 13 with allergic rhinitis, 8 urticaria, 6 food allergies and 1 allergic asthma. Male, kerion, zoophilic species infections and animal contact history were prevalent features in allergic disease combined with tinea capitis. Patients with tinea capitis plus allergic disease mostly had a family history with similar complications. M. canis and T. mentagrophytes were the most prevalent pathogens of tinea capitis in the last 15 years; atopic dermatitis/eczema and allergic rhinitis were the most frequently associated allergic diseases. Male, kerion, zoophilic pathogen and animal contact history are risk factors.
