CaHASE: a UK collaborative study on CAH in adults

R Ross

Sheffield, UK.

Congenital adrenal hyperplasia (CAH) is a genetic disorder arising from defective steroidogenesis resulting in glucocorticoid deficiency; the commonest mutation is in the gene encoding 21-hydroxylase. Lifesaving glucocorticoid treatment was introduced in the 1950s and there is now an enlarging cohort of adult patients; however, there is no consensus on management. To address this issue, the Congenital adrenal Hyperplasia Adult Study Executive (CaHASE) was formed in 2003 to study the health status of CAH patients in adulthood. Seventeen specialist Endocrinology centres around the United Kingdom recruited a cohort of 203 adult patients and gathered information on medical treatment, fertility, genetic analysis and quality of life (QoL). The CaHASE study found that adult patients are prescribed a variety of glucocorticoids including hydrocortisone, prednisone, prednisolone, dexamethasone, and combinations taken in either a circadian or reverse circadian regimen. Despite this variety in personalized treatment regimens biochemical control of CAH is only achieved in approximately a third of patients. There is evidence for poor health status in some patients with an increased incidence of obesity and osteoporosis, and impaired fertility and quality of life. The evidence suggests that these poor health outcomes relate to treatment rather than genotype. Patients receiving higher doses of glucocorticoids and the more potent synthetic glucocorticoids are more likely to suffer from obesity, insulin resistance and a reduced quality of life. Further research is required to determine whether improving management and treatment in CAH patients can improve their health.
