[HL-A antigens in patients with psoriatic rheumatism].
The authors studied HLA tissue groups for 28 specificities in 70 patients with psoriatic arthropathy (44 with pure peripheral arthropathy and 26 with axial involvement, 19 of whom also had peripheral lesions). Four antigens of this system were found with a significantly increased frequency in 70 patients in comparison with a control group of 152 normal subjects. For antigen HLA-B27, the frequency seemed very significantly increased in patients with axial involvement as compared with those without axial troubles (pc less than or equal to 0.0001) and with the controls (pc less than or equal to 0.0001). For antigen HLA-B13, the frequency was significantly increased in patients with axial involvement as compared with the controls (pc less than 0.05). Antigen HLA-Bw17 was present with significantly increased frequency as compared with the controls in the patients with peripheral involvement (pc less than 0.001). For antigen HLA-Bw38 (W16.1), the frequency in patients with or without axial involvement was significantly increased in comparison with the controls (pc less than 0.001). The interpretation of these results is discussed and the association of antigen HLA-B27 with sacro-iliac involvement once again stressed.
