Autoimmune Hyperthyroidism in Prepubertal Children

The investigators propose a multicenter retrospective study to assess clinical, biochemical, and auxological characteristics at diagnosis and during follow-up in a cohort of Caucasian pediatric patients diagnosed with autoimmune hyperthyroidism before puberty. These prepubertal patients will be compared with a control group of post-pubertal patients with Graves' disease. This study aims to enhance the understanding of autoimmune hyperthyroidism in prepubertal patients by providing a detailed evaluation of disease onset, therapeutic response, and growth-related outcomes. The inclusion of a carefully matched post-pubertal control group will allow for robust comparative analysis and identification of age-dependent clinical patterns and prognostic indicators, ultimately supporting more tailored and effective management strategies in pediatric populations at this particular age.
