• IgG-moderate background• IgA- minimal but definite granular mesangial in several
segments of the non-sclerotic glomerulus.• IgM- trace mesangial,close to negative• C3- moderate to strong vascular and Bowman’s capsule
near the vascular pole,with a few tiny mesangial granules• C1q-negative• Kappa-moderate basement membrane background with a
few mesangial granules of doubtful significance• Lambda-same as kappa• Fibrin- moderate interstitial staining• Albumin- moderate to strong basement membrane

Comment:
As well as the obvious diabetic nephropathy, the IF supports the presence of a small amount of mesangial IgA deposition,and the EM although indeterminate is at least consistent. The picture indicates a component of IgA nephropathy, but
the advanced diabetic changes are by far the predominant process here.
