Time course of natriuresis during recovery from minimal change disease

Fractional excretion of sodium (FENa, percent), plasma creatinine concentration (PCr, mg/dL), plasma renin activity, and plasma albumin concentration (PAlb, g/dL) in patients with minimal change disease both before therapy and at the time of peak diuresis during corticosteroid-induced remission. The FENa rose, in association with reductions in the plasma creatinine concentration and plasma renin activity, and a minimal elevation in the plasma albumin concentration.
