Abstract

To analise the epidemiological data (Sex, age and presence of HLA B27).Methods We included 86 patients with AS, 61 men (70.9%) and 25 women (29.1%), mean age was 48.6 ± 11.8 years (range 22 -71). The disease onset had occurred at 27.4 ± 9.2 years (range 6-53). The diagnosis of SS was made according to European Criteria and all patients with SS had keratoconjuntivitis sicca. Results Uveitis was present in 30 patients (34.9%), SS in 8 patients (9.3%) and HLA-B27 + in 63 patients (73.3%).In the group of female patients (25) we found: 22 (88%) HLA-B27 +, 10 (40%) with uveitis, 8 (32%) with SicS and 1 (4%) with SS. In the group of male patients (61) we found: 41 (67.2%) HLA-B27 +, 20 (32.8%) with uveitis, 12 (19.7%) with SicS and 7 (11.5%) with SS.In the group of HLA-B27 + patients (62 we found: 26 (41.9%) with uveitis and 6 (9.7%) with SS. In the group of HLA-B27 negative patients (24) we found: 4 (16.7%) with uveitis and 2 (8.3%) with SS. Conclusion. The prevalence of HLA-B27 was lower than in literature.. HLA-B27 was more prevalente in female.. The frequence of uveitis was higher in the HLA-B27 positive patients. . We find a high prevalence of SS in male.
