RESUMO
AIM: The first results from the French National Prader-Willi pediatric database in a cohort of 142 children aged 0.2-18.8 years are reported. This database gathers information about the endocrine dysfunctions traditionally described in Prader-Willi patients. METHODS: Questionnaires were filled in by the patients' practitioners. The coordination team of the reference center performed the statistical analysis. RESULTS: Median BMI Z-score was +1.3 for a median age of 7.1 years, and 40% of the population were overweight or obese (International Obesity Task Force 2000 criteria). Growth hormone deficiency was present in 80% of patients and 86.7% were treated, with a height gain of +1 SD and a BMI reduction of -0.8 Z-score achieved in the first year of treatment. Hypogonadism was present in 49% of patients, and hypothyroidism in 24.4%. Glucose intolerance was found in 4% of patients, but no diabetes mellitus was detected in the 74 patients explored. CONCLUSION: Our report gives an overview of endocrine dysfunctions recorded in a large registry database of French children and adolescents with Prader-Willi syndrome. The database, which now encompasses six southern regions of France, will be further extended to the whole country and to adult patients.
