This report describes two Egyptian patients who presented with the nephrotic syndrome and concurrent infections with Schistosoma mansoni and Salmonella paratyphi A. Unlike similar cases previously reported from this unit, these patients did not respond to antimicrobial and antischistosomal therapy, and their renal biopsies demonstrated amyloidosis. These two case reports and several experimental observations suggest that chronic schistosomiasis and salmonellosis may lead to secondary amyloidosis in susceptible individuals.
