    Abstract

    Abstract: A cohort of 139 hemophiliacs was typed for HLA D region genes by means of restriction fragment length polymorphisms (RFLPs) detected by HLA DQ and DR gene probes. Disease progression was studied in the 65 HIV antibody‐positive patients, who were infected by contaminated clotting factor before 1985. Strong associations were found between disease progression in HIV‐infected patients and allelic DNA fragments revealed by a DQα cDNA probe. A 5.5 kb fragment was reduced in frequency and a 4.6 kb fragment increased in frequency (p < 0.005) in the faster progressing group, as measured both by development of CDC Category IV clinical symptoms and CD4 number <200 × 106/1. These results correlate with DR types deduced from the RFLP patterns revealed by DRβ and DQα gene probes. A decrease in DR4 and an increase in both DR5 and the DR3 subtype found in the A1 B8 DR3 haplotype were associated with disease progression (p < 0.05). 1992 Blackwell Munksgaard
