A semiquantitative light microscopic study of 274 renal biopsy and 12 nephrectomy specimens was carried out to assess the frequency and severity o f tubulitis (mononuclear leukocytes in the renal tubular wall) in all common glomerular diseases, diabetic nephropathy, renal amyloidosis and renal artery stenosis. The extent o f interstitial inflammatory infiltrates and severity o f interstitial fibrosis were also graded. Tubulitis was 1) frequent in crescentic glomerulonephritis (GN) with pauci-immune, linear and granular immune deposits, renal artery stenosis, diabetic nephropathy, lupus GN o f WHO type IV, and IgA GN; 2) rare in minimal change and idiopathic membranous nephropathy; 3) usually severe in crescentic GN and renal artery stenosis; and 4) predominantly located in atrophic tubules in renal artery stenosis, diabetic nephropathy and IgA GN. The most important parameter for the grading o f tubulitis was interstitial infiltration. However, no correlation was found between the grades o f tubulitis, interstitial infiltrates and interstitial fibrosis in crescentic and lupus GN. It is suggested that renal ischemic injury, by eliciting expression o f groin flammatory cytokines and neo-antigens in the tubulointerstitial space, might play a role in the development o f tubulitis in vascular and glomerular renal diseases.
