[Primary nephrotic syndrome in the black African child].

Idiopathic nephrotic syndrome (INS) in black African children differs from that of children in temperate areas. The main differences are the high rate of corticosteroid non-responders and the low rate of minimal change glomerulopathy in black African children, possibly related to a racial factor. The identification of a high corticosensibility in certain African regions (Togo and Ghana) can lead to the identification of an ethnic factor. Further genetic studies should be carried out in order to provide a better approach to INS in Africa.
