title: The spectrum of renal histopathology in patients with significant proteinuria in Vanuatu.
abstract: Renal biopsies were performed on 21 of 27 Melanesian patients presenting with significant proteinuria in Vanuatu from 1983 to 1985. All patients had more than 2 g of proteinuria per 24 hours or clinical evidence of the nephrotic syndrome. The average age of the patients who were biopsied was 31 years. Three of the 21 patients had evidence of active malaria at the time of presentation, and all of these patients had Plasmodium falciparum. Renal histopathology revealed that six patients (29%) had amyloidosis and five patients (24%) had mesangiocapillary glomerulonephritis (type 1). Of particular note was the fact that only one patient had membranous glomerulonephropathy and only one patient had minimal change nephrotic syndrome, the two most common lesions reported in nephrotic patients in Europe and the United States. Thus, the spectrum of renal histopathology in patients presenting in Vanuatu with significant proteinuria is very different from that seen in Western Countries.
