Abstract
PURPOSE: There have been conflicting data on the relative frequency of common forms of primary nephrotic syndrome (PNS). We undertook this study to look at the causes of PNS in the latest decade from our biopsy population, with a special attention to breakdown by race. METHODS: Retrospective chart review of all cases of adult PNS extracted from a database of 1388 cases for the last 10 years. We were careful to exclude patients with secondary disease and without the full nephrotic syndrome. RESULTS: There were 115 cases of PNS. Overall, MN was the most common lesion (40.0%), followed by minimal change disease (MCD) (34.0%), focal segmental glomerulosclerosis (FSGS) (13.0%), and IgA nephropathy (IgAN) (11.3%). Among whites, MN was the most common cause of NS (41.7%), followed by MCD (33.3%), IgAN (16.7%), and FSGS (6.3%). Among blacks, FSGS was the most common lesion (33.3%) followed closely by MN (29.6%), and MCD (26.0%). IgAN was present in 7.4%. Among multiracial patients (MR), MGN was the most common (50%) followed by MCD (45.5%) and FSGS (4.5%). In Asians, MCD (50.1%) and MGN (33.3%) were the most common, followed by FSGS and IgAN with 8.3% each. CONCLUSIONS: MN and MCD were the most common causes of PNS in our population, with FSGS much less common overall. This is especially the case among whites and MR. Among blacks, MN and FSGS were almost codominant causes. The apparent decreased prevalence of FSGS may be related to more effective exclusion of secondary and maladaptive causes.
