Introduction
A recent immuno-electron microscopy (IM-EM) study was conducted on a series of patients with [1] schistosomal glomerulopathy (SG) using a monoclonal anti-Schistosoma mansoni antibody obtained from adult worms. IM-EM allows precise localization of schistosomal antigen deposits in glomerular structures. Based on this work and on the experience accumulated along the years with this disease at the Institute of Tropical Medicine and at the Nephrology Division of the Hospital das Clinicas (São Paulo University Medical School), we review here the difficulties involved in diagnosing SG and emphasize some differences from the Egyptian equivalent reviewed by Barsoum et al. [2,3].
In his editorial review, Barsoum [2] suggested the classification of SG into five histopathological categories: mesangio-proliferative glomerulonephritis (GN), membrano-proliferative glomerulonephritis, focal and segmental glomerulosclerosis (FSGS), exudative glomerulonephritis and amyloidosis. Exudative glomerulonephritis was associated with chronic salmonellosis, amyloidosis and with both recurrent salmonellosis and
