The nephrotic syndrome in the Sudan with special reference to schistosomal nephropathy. A preliminary morphological study.

The morphology of 68 renal biopsies from the Sudan is analysed. Schistosomal infection was more common among the nephrotic patients than in the average population (32% against less than 1%). In the schistosomal group the high incidence of focal sclerosing glomerulonephritis (28%) and of secondary amyloidosis (38%) was remarkable. The history is described of a boy in whom repeated biopsies showed the decrease of glomerular amyloid depositions accompanied by mesangial cell proliferation following treatment for schistosomiasis.
