Patients with progressive systemic sclerosis (PSS; scleroderma) were typed for the HLA-A, -B, and -DR antigens. No significant differences in the frequencies of any HLA-A or -B antigen were found. In the subgroup of patients with PSS and diffuse scleroderma (PSS-DS), the frequency of Bw35 was increased (0.30 vs 0.17 in controls; p less than 0.005, corrected P greater than 0.2). Although patients with PSS-DS also had an increased frequency of DR1 antigen (0.27 vs 0.12 in local controls; P less than 0.005, corrected P less than 0.05), no association between Bw35 and DR1 antigens could be detected. We found no increase in the frequencies of the DR3 or DR5 antigens in patients with PSS. However, in a subset of PSS patients with pulmonary fibrosis, an increase in DR3 and a decrease in DR4 antigens (P less than 0.005) were observed. Serum antibodies to centromere occurred more frequently in DR1-positive than DR/-negative patients (0.46 vs 0.18; P less than 0.005). This study of a large number of patients with PSS failed to confirm previously reported associations of PSS with the HLA-B8/DR3 haplotype of HLA-DR5 antigen.
