Phospholipase A2 receptor and sarcoidosis-associated membranous nephropathy

Nephrol Dial Transplant. 2015 Jun;30(6):1047-50. doi: 10.1093/ndt/gfv080. Epub 2015 Apr 2.


Of the glomerulonephritis associated with sarcoidosis, membranous nephropathy (MN) is the most prevalent. Coincidence or a causal relationship between these two diseases is unclear. Here, we present for the first time a high prevalence of PLA2R-related MN among patients with MN associated with active sarcoidosis. Our results suggest some causal link between sarcoidosis and PLA2R-related MN. Detection of anti-PLA2R antibodies in serum or PLA2R antigen in biopsy should not be taken as evidence against a secondary cause, particularly sarcoidosis. This important observation can affect treatment decision in these patients.

Keywords: membranous nephropathy; phospholipase A2 receptor; sarcoidosis.
