[The characteristics of HLA antigen distribution among patients with persistent lambliasis].

Fifty patients suffering from persistent giardiasis and 257 healthy persons from Uzbekistan were examined. HLA-typing was carried out by the Terasaki microlymphocytotoxicity technique. The patients with persistent giardiasis were characterized as a significant prevalence of HLA-B5, HLA-B14, HLA-DR3, DR4, DR7 and haplotypes HLA-A9-B5 and A1-B5. These haplotypes and HLA antigens can be considered as markers of predisposition to persistent giardiasis.
