Electronic Registry of Male Patients With Congenital Adrenal Hyperplasia 21-hydroxylase Deficiency

Observational, retrospective, prospective, single-center cohort study conducted at the UOC of Endocrinology and Diabetes Prevention and Treatment of IRCCS AOU of Bologna. Participation in the Registry will be offered consecutively to any patient with the disease, newly diagnosed or with documented diagnosis made at another Center, at any stage of the disease. Laboratory tests, imaging study for patient monitoring, and care procedures all will be conducted in accordance with normal clinical practice. For the retrospective phase, patients whose diagnosis of CAH was made on or after 01/01/1960 will be enrolled, and observation related to this phase will be extended until this study is approved. The study population is partly from direct access at the U.O.C. of Endocrinology and Diabetes Prevention and Treatment, as the regional referral center for this rare disease (congenital adrenal hyperplasia). The potentially involved cohort is estimated to be about 30 patients at the time the registry was established. It is assumed that both retrospective and prospective phases can be completed in 15 subjects and retrospective alone in the remaining 15 subjects. The registry may become the reference for calculating incidence and prevalence in Emilia Romagna of the disease under study.
