We studied HLA antigen distribution of 50 heterosexual partners of HIV+ drug abusers with more than 1 year of sexual exposure to HIV, 36 children born to seropositive mothers and 61 haemophiliac patients exposed to presumably infectious clotting factor concentrates. B52 and B44 antigens were associated with HIV resistance while B51 was associated with HIV susceptibility. Forty-nine HIV+ drug abusers, spouses of heterosexual partners studied and 25 HIV+ mothers of the children were also typed. DR11 phenotype was associated with infectiousness of HIV+ subjects. Our data suggest that the HLA region controls susceptibility to infection with HIV and infectiousness of HIV+ subjects in different risk groups.
我们研究了50名与HIV阳性药物滥用者有超过1年性接触的异性伴侣、36名血清反应阳性母亲所生子女以及61名接触过可能具有传染性的凝血因子浓缩物的血友病患者的HLA抗原分布情况。B52和B44抗原与HIV抗性相关,而B51与HIV易感性相关。还对49名HIV阳性药物滥用者、所研究异性伴侣的配偶以及25名子女的HIV阳性母亲进行了分型。DR11表型与HIV阳性受试者的传染性相关。我们的数据表明,HLA区域控制着不同风险群体对HIV感染的易感性以及HIV阳性受试者的传染性。
