Serum immunoglobins in Nigerians with urinary schistosomiasis

Serum levels of immuno-globulin G, A, M, D and E were determined using single radial immuno-diffusion technique in 52 Nigerian primary school children with urinary schistosomiasis and 39 age and sex matched controls. The mean values of IgA, IgM and IgE in the school children with S. haematobium infection were significantly higher than in controls. These findings suggest that urinary schistosomiasis in these subjects was in the acute stage.
