End-stage renal disease of the Tunisian child: epidemiology, etiologies, and outcome.

From December 1989 to December 1993, 90 children under 15 years were admitted to our department for end-stage renal disease; 9 children were less than 5 years and 28 were aged between 5 and 10 years. The sex ratio (M/F) of the children was 2.1. The estimated incidence of pediatric end-stage renal disease in Tunisia is 7 new cases per year and per million child population under 15 years. The chief etiologies of end-stage renal disease are glomerulonephritis (19%), hereditary nephropathies (29%), and malformative uropathies (13%); 26% of the end-stage renal diseases are of unknown etiologies. Our findings, compared with the European data, show a particularly high frequency of primary hyperoxaluria (13.5%) and an unusual proportion of male subjects.
