    Notes: Summary: Most cases of adult type IgA nephropathy (IgAN) have an insidious onset and asymptomatic course. However, some patients reveal recurrent macroscopic haematuria following episodes of respiratory or urinary tract infections. In order to clarify the correlation between clinical features and histological alterations or prognosis, 42 cases of early stage IgAN and 40 cases with acute exacerbation episodes were investigated and compared with a control group. Early stage cases were defined as having had a renal biopsy within 1 year after the first detection of urinary abnormalities, and had normal urinary findings within the 12 months before the first detection of urinary abnormalities. Acute exacerbation cases were defined as macroscopic haematuria or worsening of urinary abnormalities after acute infectious episodes and undergoing a renal biopsy within 120 days after the onset of these episodes. the early stage cases had better renal function and lower systolic and diastolic blood pressure than that of control group. They also showed milder changes in mesangial cell proliferation, mesangial matrix increase, totally sclerotic glomeruli, and tubulo-interstitial changes. However, it is important to note that glomerular and interstitial sclerotic changes were observed even in early stage cases. Endothelial detachment was noticed more frequently in the early stage cases. Acute exacerbation cases revealed lesions of endocapillary proliferation, mesangiolysis and endothelial detachment more frequently, although these changes were segmental in each glomerulus. There was no statistical difference in disease prognosis between cases with and without acute exacerbation. These data indicated that there are characteristic histological changes in early stage cases and acute exacerbation cases of IgAN.

    Notes: Abstract Diabetic nephropathy is a major cause of chronic renal failure in Japan, and the prevalence rate has markedly increased during the past decade. Diabetic nephropathy shows various specific histological changes not only in glomeruli but also in the interstitial region. Nodular, diffuse, and exudative lesions, so-called diabetic glomerulosclerosis, are well known as glomerular lesions. At first, they were historically evaluated only by light microscopy, and thus which components of the glomeruli were modified was not sufficiently clear. Subsequent electron microscopic studies clarified that the expansion of the mesangial matrix was the true form of nodular and diffuse lesions, and that insudated serum substance was the real appearance of an exudative lesion. Interstitial lesions also exhibit specific features in diabetic nephropathy. In electron microscopic studies, it was proved that the size of mitochondria and thickness of the tubular basement membrane were increased in diabetic nephropathy. In this review, we introduce typical electron microscopic findings in diabetic nephropathy and recent opinions on the progression of diabetic nephropathy.
