  • Title: Clinico-pathological features of the nephrotic syndrome in South African children.
    Author: Coovadia HM, Adhikari M, Morel-Maroger L.
    Journal: Q J Med; 1979 Jan; 48(189):77-91. PubMed ID: 482593.
    Abstract:
    One hundred and thirty children of whom 74 were Africans and 56 Indians with contrasting clinicopathological patterns of the nephrotic syndrome are described. Eighty-six per cent of African children had obvious structural glomerular lesions which were associated with unresponsiveness to steroids while 75 per cent of Indians had minimal change nephrotic syndrome which was steroid responsive. The treatment history of a further 41 unbiopsied children with nephrotic syndrome (nine Africans, 32 Indians) support and emphasize this difference. Extramembranous and a tropical variety of extramembranous (36.5 per cent) together with proliferative (20.2 per cent) lesions accounted for most of the histological types in African children. The disease in Indian children was similar to that in other countries in age of onset, sex distribution, frequency of histological types and steroid responsiveness although there was a preponderance of frequent relapsers (69 per cent). Africans differed from children in other continents in the frequency of histological categories (therefore in steroid responsiveness) and occasionally in clinical behaviour. They also differed from children in tropical Africa in a lower incidence of the disease, male dominance and absence of malarial nephropathy. The aetiology of nephrotic syndrome in nearly all the children remains unidentified.
