HLA in schistosoma haematobium [Sh]: a special pattern in cancer bladder and hepatosplenomegaly

Estimation of HLA [ABC] antigen frequency was done in 65 patients with various manifestations of SH, in a trial to a possible association of these genetic markers and disease susceptibility to SH and/or in the development of various complications of the disease. It was concluded that, the close association between HLA antigens and S. hematobium infestation can provide some evidence that susceptibility or resistance to schistosomiasis is determined by genetic factors. Susceptibility of individuals may be based on the presence of A11, B21 contributes to resistance to infection. Individuals possessing A30, Cw4 may be prone to the development of the hepatosplenic form of the disease while A30, B35 and CwS more prone to the development of malignant bladder
