==Overview== | |||
Nephrotic syndrome can occur primarily or due to systemic diseases. The most common cause of nephrotic syndrome in children is [[minimal change disease]]. The most common primary causes in adults are [[focal segmental glomerulosclerosis]] (FSGS), [[minimal change disease]], and [[membranous nephropathy]]. Approximately 30 percent of adults have secondary nephrotic syndrome due to [[diabetes mellitus]], [[SLE]], or [[amyloidosis]]. The most common cause of secondary nephrotic syndrome in adults is [[diabetes mellitus]]. | |||

Overview
Nephrotic syndrome can occur primarily or due to systemic diseases. The most common cause of nephrotic syndrome in children is minimal change disease. The most common primary causes in adults are focal segmental glomerulosclerosis (FSGS), minimal change disease, and membranous nephropathy. Approximately 30 percent of adults have secondary nephrotic syndrome due to diabetes mellitus, SLE, or amyloidosis. The most common cause of secondary nephrotic syndrome in adults is diabetes mellitus.
Causes
Nephrotic syndrome can occur primarily or due to systemic diseases. The most common cause of nephrotic syndrome in children is minimal change disease. The most common primary causes in adults are focal segmental glomerulosclerosis (FSGS), minimal change disease, and membranous nephropathy. Approximately 30 percent of adults have secondary nephrotic syndrome due to diabetes mellitus, SLE, or amyloidosis.[1][2][3][4][5][6][7]
Primary Causes
Primary renal disorders, such as primary glomerulonephritides, may cause primary nephrotic syndrome. Differentiation between different types of glomerular diseases is often made by clinical suspicion and by renal biopsy, which includes light microscopy, immunofluorescence, and ideally electron microscopy.
Secondary Causes
Secondary causes of renal disorders cause secondary nephrotic syndrome. The most common cause of secondary nephrotic syndrome in adults is diabetes mellitus. Shown below is a table of the causes of nephrotic syndrome by age group.[8]
