Abstract
Background Men with early-onset androgenetic alopecia (AGA) often have an abnormal hormonal milieu. Objective To ascertain the clinico-phenotypic characteristics and the prevalence of hormonal and metabolic changes in men with early-onset AGA. Methods Consecutive male patients less than 30 years of age with a Norwood-Hamilton grade ≥3 AGA were recruited in this comparative cross-sectional study. After endocrine evaluation they were classified into two groups, that is, Group A consisting of subjects with an altered hormonal profile and Group B with normal hormonal profiles. The groups were assessed for differences in disease phenotype and severity (Norwood-Hamilton grade), insulin resistance and parameters of metabolic syndrome (ATP III guidelines). Results Altered hormonal profiles were seen in 34 of the 100 subjects with AGA, while insulin resistance and metabolic syndrome were noted in 44 and 26 respectively. Altered hormonal profiles were significantly associated with insulin resistance and severe alopecia (grade 4 and above Hamilton-Norwood Scale). Insulin resistant Group A patients had a significantly higher prevalence of severe alopecia (>grade 4) (P = 0.0036). The prevalence of metabolic syndrome was similar in both groups. Limitation The cross sectional study design was a drawback of this study. Further, a control arm without AGA was not included and the sample size of 100 was selected arbitrarily. Conclusion An altered hormonal profile and insulin resistance was noted in a third of the males with early-onset AGA. Subjects with altered hormonal profiles had a higher prevalence of insulin resistance and were likely to have severe grades of AGA.
