APPLYING DECISION-ANALYSIS TO MANAGEMENT OF ADOLESCENT IDIOPATHIC NEPHROTIC SYNDROME

Due to the concern that adolescents presenting with nephrotic syndrome are less likely to have minimal change disease than younger children, pediatric nephrologists have tended toward renal biopsy-tailored trea tment rather than corticosteroid use in this population. The need for biopsy prior to treatment of nephrotic syndrome in adults has been cha llenged, A similar challenge to the clinical need for this procedure i n adolescents with idiopathic nephrotic syndrome is raised here, The p rinciples of medical decision analysis were applied and calculations w ere made with the Decision Maker computer program. The life expectancy of an adolescent who receives biopsy-tailored treatment was found to be no different from that of an adolescent who receives empiric cortic osteroid treatment. We conclude that renal biopsy is not mandatory for the clinical management of adolescents with idiopathic nephrotic synd rome. Prognostically, a response, or lack thereof, to empiric corticos teroid therapy may be just as informative as a histological diagnosis.
