Burden of Chronic Dermatophytosis in a Tertiary Care Hospital: Interaction of Fungal Virulence and Host Immunity.

ABSTRACT

Dermatophytosis is caused by keratinophilic dermatophytes and affects the superficial skin and its appendages. The nature of infection and response to treatment is influenced by host-pathogen factors like duration and severity of disease, prior drug history and type of causative organism. In our study, the burden of dermatophytosis affecting glabrous skin saw a rise in recalcitrant and reinfection cases with only 1.6% achieving complete cure. Chronicity of dermatophytic infection was reflected in the high serum IgE levels and immediate hypersensitivity reactions. Hence, it becomes pertinent for clinicians to identify the non-responders and modify therapy to achieve clinical cure with fungal clearance confirmed by mycological tools.
