HLA-A, -B and -C specificities were determined in 100 Egyptians living and originating from the region of the Nile Delta. The pattern of antigen frequencies were similar to those of Berber populations living in North Africa with some exceptions compatible with the Semitic contribution to the Egyptian population.

20 patients of schistosomal hepatic fibrosis and splenomegaly (SHF) with and without haematemesis were examined. Typing for HLA‐A, B and C antigens in these patients were compared with those of a group of 100 Egyptian controls. The study showed the presence of an association between HLA‐A1 and B5 antigens in SHF cases. However, there was no significant association between HLA antigens and SHF cases with haematemesis.
