By investigating a group of 67 unrelated adult persons suffering from
vitiligo it was found that antigens HLA-A2 and HLA-Dw7 differed in the
ir frequencies in comparison to those observed in the healthy populati
on. The antigen HLA-A2 was found in 76.12% of patients compared to 43.
95% in the control group (chi(2) = 25.61, P < 0.005, RR = 4.07). The a
ntigen HLA-Dw7 was present in 56.71% of patients compared to 15.8% in
the healthy population (chi(2) = 26.55, P < 0.0001, RR = 6.98). No oth
er significant deviations in the frequencies of investigated antigens
were observed.
