Prevalence of autoimmune thyroid diseases among the Turner Syndrome patients: Meta-analysis of cross sectional studies

Objective: This meta-analysis was done to estimate the prevalence of autoimmune thyroid diseases (ATDs) in Turner Syndrome patients, and to determine the clinical status of thyroid autoimmune diseases that occur frequently in association with Turner Syndrome. Results: A total of 18 studies were included in the meta-analysis. The pooled overall prevalence of autoimmune thyroid diseases in Turner Syndrome patients was 38.6% (95% CI 29.7-47.6%), with 12.7% (95% CI 9.30-16.1%) of them had clinical hypothyroidism and 2.6% (95% CI 1.5-3.8%) had hyperthyroidism. I-squared test had a high result of heterogeneity. In subgroup analyses, the prevalence of ATDs was higher in the European region than Asian region. Autoimmune thyroid diseases are commonly associated with Turner Syndrome. Early detection of thyroid diseases by optimal screening among children with Turner Syndrome is required to ensure effective management. © 2018 The Author(s).
