title: [Evaluation of corticosteroid replacement therapy and its effect on bones in Addison's disease].
abstract: Assessment of patients on steroid replacement therapy is important to avoid the consequences of overtreatment such as osteoporosis. The aim of this prospective study is to evaluate the severity and the etiology of osteopenia in 24 patients (15 women, 9 men) with Addison's disease receiving 30 mg hydrocortisone. Mean age of patients was 55 15 years. Osteoporosis, diagnosed by the measurement of bone mineral density (BMD) at the level of lumbar spine and right hip, was found in 58% of patients, i.e. in 10 women and 4 men. The latter had normal testosterone levels while seven women had an early menopause, the etiology of their Addison's disease being autoimmune. Three were on hormonotherapy. Correlations were found between BMD in the femoral neck and hip and the dose of hydrocortisone (mg/m(2)/day; mg/kg/day), the duration of treatment and 24 hr-cortisoluria/g creatinine. Multivariate analysis shows that 24-hr cortisoluria/g creatinine is a good predictor of BMD values. Thus, osteoporosis is frequent in Addison's disease and cortisoluria could be a useful tool to predict this complication.
