Moreover, the new Oxford MEST-C (mesangial hypercellularity, endocapillary hypercellularity, segmental sclerosis, tubular atrophy/interstitial fibrosis, crescents) scoring system 2016 does not include immunostains, although the location of glomerular IgA along with IgG immune deposits demonstrated by immunofluorescence studies correlates with mesangial and endocapillary hypercellularity, which according to the new MEST-C score are strong prognostic indicators in IgA nephropathy patients [4]. This evidence concerns the gene CD79A and IgA glomerulonephritis.
