PY - 2017 T2 - CURRENT Diagnosis & Treatment: Nephrology & Hypertension, 2e AB - Minimal change disease (MCD) is a term used to describe the pathologic findings in a group of patients who present with heavy proteinuria, typically leading to nephrotic syndrome. On kidney biopsy the findings include apparently normal glomeruli on light microscopy, negative immunofluorescence, and diffuse podocyte foot process effacement on electron microscopy (Figure 25–1). While occasionally MCD may be secondary to another condition such as lymphoma, in the majority of cases MCD is one of the idiopathic renal diseases. Because MCD is most likely to be the diagnosis in children presenting with the nephrotic syndrome, the majority of children do not undergo a kidney biopsy, but receive empiric treatment without one. Seventy percent of children with MCD present before age 5 years, and 20–30% of adolescents who present with nephrotic syndrome have MCD. Nevertheless, MCD is the third most common finding in adults with nephrotic syndrome, after membranous nephropathy and focal, segmental glomerulosclerosis (FSGS). The typical patient with MCD responds to therapy but experiences recurrent relapses.
