CD79A and glomerulonephritis: With the limitation that the number of non-LN patients with a PCR≥1 g/g (n = 7) was reduced and related to biopsy proven non-LN glomerulonephritis (IgA deposition x2, post-infectious, minimal change nephropathy, and focal segmental glomerulosclerosis) or a chronic kidney disease at end stage (CDK5, n = 5), for these limited cases we confirmed at PCR≥1 g/g a better discrimination with LN-A when using the urinary sCD163/proteinuria ratio instead of the sCD163/creatinuria ratio (p = 0.0009 versus p = 0.09), which needs further investigation.
