PREVALENCE OF SALT‐LOSING AMONG CONGENITAL ADRENAL HYPERPLASIA PATIENTS

Abstract
SUMMARY: Among clinic patients with congenital adrenal hyperplasia (CAH) the observed frequency of salt‐losing has increased significantly over the past 30 years. Comparing estimates from various clinics, older estimates of the frequency of salt‐losing are lower than estimates cited in more recent literature. Within the patient population of a single long‐established clinic, an increase in the frequency of salt‐losing can also be observed. It is likely that the increase in the frequency of salt‐losing CAH reflects improved case finding and survival of salt‐losing patients. Based on reports of recent populations of CAH patients, the frequency of salt‐losing among CAH patients is approximately 66%.
