Quality of life in individuals with primary hyperhidrosis: a systematic review and meta-analysis.

Abstract

Hyperhidrosis can be a debilitating disease that leads to the deterioration of well-being. In this study, the objective was to compare the health-related quality of life (HRQOL) in individuals with and without hyperhidrosis by conducting a systematic review and meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Meta-analysis Of Observational Studies in Epidemiology checklist were employed. We systematically searched Cochrane Library, Embase and PubMed. Two authors independently assessed the literature and extracted the data. The risk of bias was assessed using the Newcastle-Ottawa Scale. A random-effects model was employed. The heterogeneity was determined using I2. Eleven studies met the eligibility criteria comprising 4297 and 147,604 participants with and without hyperhidrosis, respectively. The risk of bias ranged from high quality to very high risk of bias. The individuals with hyperhidrosis had a higher Dermatology Life Quality Index (mean difference 8.53; 95% confidence interval 3.47, 13.58; p = 0.0009) and a lower mental component summary of the short form-12 or -36 (mean difference -6.15; 95% confidence interval -9.00, -3.30; p < 0.0001) than the control individuals. No difference was found for the physical component summary score of the short form-12 or -36 (mean difference -0.88; 95% confidence interval -1.88, 0.12; p = 0.085). Studies using patient-reported outcomes, not included in the meta-analysis, showed similar results. Individuals with hyperhidrosis experience a reduced HRQOL that is clinically meaningful and leads to perceivable deteriorations in their well-being. The evidence shows a high degree of heterogeneity, which warrants additional studies.
