Twenty-one Israeli Jewish pemphigus vulgaris (PV) patients were studied for the HLA-D lymphocyte defined determinants and the serologically defined antigens of the HLA-A, B, and DR series. HLA-D typing revealed that Dw10 is significantly associated with PV: 86% of patients vs 18% of controls carried Dw10, and DR4 was present in 86% of patients as compared to 38% in the controls. The most striking observation was that all Dw10 positive patients were also positive for DR4, and no other patient carried DR4 alone. The relative risk for a Dw10-DR4 carrier to develop PV was estimated at 31.9, higher than that observed for Dw10 alone (RR 26.7) or DR4 alone (RR 9.6). Probably HLA-Dw10 predisposes for pemphigus vulgaris.
