title: Correlation of paramesangial deposits and glomerular sclerosis and/or hyalinosis in patients with IgA nephropathy.
abstract: Correlation of paramesangial deposits ("hemispherical body") and glomerular sclerosis and/or hyalinosis was examined by light microscopical analysis in 40 patients of IgA nephropathy. Correlation of paramesangial deposits and intensity of IgA or C3 deposition in glomeruli was also evaluated in these patients. The number of paramesangial deposits was markedly increased in patients with moderate and advanced stages of IgA nephropathy who showed marked glomerular sclerosis and/or hyalinosis. There was a significant correlation between the number of paramesangial deposits and the intensity of IgA deposits in glomeruli. It is suggested that the accumulation of paramesangial deposits might induce severe glomerular injuries such as glomerular sclerosis and/or hyalinosis.
