The Epidemiological and Mycological Profile of Superficial Mycoses in India from 2015 to 2021: A Systematic Review

ABSTRACT

Background: The epidemiological and mycological patterns of superficial mycoses across various geographic regions of India across the last few years are changing. Objective: This study was performed to evaluate the epidemiological and mycological profile of superficial mycoses in India between 2015 and 2021. Methods: In this systematic review, the PubMed database was searched for all observational studies published between January 1, 2015, and December 31, 2021, which had evaluated the clinico‑mycological profile of superficial mycoses among outpatients from various parts of India. Descriptive statistics was used to represent the results. Results: Forty studies(21 from the north, three from the northeast, five from the east, seven from the south, one from the west, and three from multiple regions of India) were included. Male patients and those of the age group of 21–40 years were most commonly affected. The proportion of dermatophytes as causative organisms was consistently high across all regions and throughout the study period (23.6%–100%). Among dermatophytes, the proportion of Trichophyton mentagrophyte (14.0%–97.2%) and Trichophyton rubrum (0%–69.1%) was consistently high across all regions. The prevalence of T. mentagrophyte showed a rising trend, while that T. rubrum showed a declining trend from 2015 to 2021. Conclusions: The epidemiological and mycological pattern of superficial mycoses showed a fairly similar trend across various regions of India from 2015 to 2021. Dermatophytes were the main causative agents of superficial mycoses; the most common species were T. mentagrophyte and T. rubrum. A rising trend of T. Mentagrophyte infection was found.
