Epidemiological Analysis of Steroid-Modified Tinea in the Back and Upper Limb Regions: Insights from India

Description

Abstract (English)

Abstract
Background: India, with its diverse climate, population, and healthcare practices, serves as an intriguing
backdrop for this investigation. The country's tropical and subtropical regions, coupled with socio-economic
factors, contribute to an environment conducive to dermatophytic infections. The widespread and inappropriate
use of topical steroids has emerged as a significant contributing factor to the modification and exacerbation of
dermatophytoses, posing challenges in diagnosis and management.
Material and Methods: A Prospective Observational Cross-Sectional Study was conducted at the department
of Dermatology, Venereology, and Leprology of Teerthanker Mahaveer Medical College and Research Centre
in Moradabad, India. The study included 500 participants aged 1-70 years with a history of topical and/or
systemic corticosteroid use and positive KOH results. Pregnant women were excluded. The 18-month study
aimed to explore atypical patterns associated with steroid-modified tinea corporis in the Back and Upper Limb
Regions.
Results: Results showed that predominant annular shape in 88% of cases, with polygonal-shaped lesions
comprising 12%. Erythema reveals that 54.3% of lesions exhibit erythema, contrasting with 45.7% showing no
signs. Results also emphasize a significant majority (94.1%) lacking central clearing, while 5.9% display this
feature.
Conclusion: Steroid-modified tinea corporis presents a growing public health concern in India, leading to
atypical and chronic presentations challenging conventional treatment. Understanding diverse clinical patterns
and risk factors is crucial for effective management and prevention. The study underscores the need for targeted
interventions to curb steroid misuse, mitigating the rising burden of dermatophytosis. The escalating prevalence
demands comprehensive strategies for nuanced diagnosis and treatment.
