Increased frequency of HLA--DRw2 and DRw3 in multiple sclerosis.

Previous studies of multiple sclerosis patients showed the existence of a positive association between multiple sclerosis and HLA--A3 and --B7, as well as a negative association with B12. These observations have been confirmed. In addition, a more marked association has been observed with two recently identified B-cell antigens, DRw2 and DRw3, closely related to the HLA--D locus. The presence of cold lymphocytotoxic antibodies was found to bear no relationship with those two specificities. These results suggest that two genes of the HLA--DR region may play a role in the pathogenesis of multiple sclerosis.

Evidence for an HLA-linked resistance gene in Buerger's disease.

The incidence of Thromboangiitis Obliterans in brothers and the high prevalence in some ethnic groups have led us to investigate the histocompatibility HLA-A, B and DR antigens of 46 Buerger's disease patients. The main result indicates a marked decreased freqeuncy of the B12 antigen: 2.2% vs 28% in controls. Our study suggests that Buerger's disease is, on the basis of HLA antigens, a distinct immunogenetic entity and not a particular form of arteriosclerosis. Moreover, this disorder may represent a clue to the existence of resistance genes linked to HLA.

A screening program for anti-DR typing reagents.

A total of 694 sera have been tested in a screening program aimed at identifying monospecific reagents for HLA--DR typing. All sera were first tested on a panel of enriched B and T cells without absorption on platelets. Only sera reacting more frequently on B than on T lymphocytes were absorbed on platelets and retested on the panel. This procedure saved a considerable amount of platelets and proved to be reasonably efficient. One-hundred-and-fifty sera were found to contain an anti-B cell antibody. Significantly less frequent B cell reactivity was found when HLA--A, --B, --C antibodies could not be detected. Twenty-five sera were demonstrated to be specific for well-defined DR antigens.

HLA and glioma.

HLA typing of 80 glioma patients was determined and the antigen frequencies were compared with 176 normal controls. Increased phenotypic frequencies of Bw35 and DRw1 were observed, but when P values were corrected by the number of antigens tested (35), the results were no longer significant.

[HL-A D antigens from B-lymphocytes and susceptibility to certain diseases].

The discovery of many associations between HLA and human diseases has emphasized the biologic importance of the main histocompatibility system in man. The recent findings from specific immune response genes (Ir locus) mapping within the H2 region of the mouse have led to systematic study of the similar D locus mapping within the HLA region in man. In this study the frequency of a number of HLA-D antigens has been determined in normal individuals and in patients with four diseases selected in view of their genetic background: juvenile diabetes, multiple sclerosis, grass pollinosis and acute leukemia. In each a significant association has been found with a specific HLA-D antigen: DW3 in juvenile diabetes and grass pollinosis, DW2 in multiple sclerosis, and DW7 in acute lymphoblastic leukemia.
