[HL-A and ankylosing spondylarthritis]

With the investigation of HL A phenotypes of 133 patients with an akylozing spondylarthritis, 110 males and 23 females, confirmed incidence of antigen B 27 was established in 87.96 per cent versus 10.78 per cent of 1085 control healthy subjects. The families of 24 patients were also examined with a total of 27 subjects HLA-B27 positive relations, among them 11 cases of SA with a latent course so far. The results from those exminations reveal that HLA-B27 antigen investigations could aid making the diagnosis in cases, suspected of SA, together with the other diagnostic methods.
