AB0534 Proportion of sjogren's syndrome patients referred to oral specialists at a rheumatology tertiary centre and factors associated with their referral
SLE, Sjögren's and APS – treatment
between the groups, univariate regression analyses were made. In all analyses significance level was set at 0.05. Abstract AB0533 -Table 1. Sociodemographic and clinical characteristics according to treatment groups Results: A total of 824 SLE patients were included, mean age of 47.3±14.4 years, 92.3% female. The mean age at first symptoms was 31.6±14.1 and at SLE diagnosis of 34.1±14.3 years. On their last assessment, 678 (82.3%) were being treated with antimalarials, 463 (56.2%)
... s, 343 (41.6%) immunosuppressants (149 AZA, 99 MM, 67 MTX, 14 cyclosporine, 11 cyclophosphamide, 3 leflunomide) , 53 (6.4%) biologics (32 rituximab, 21 belimumab) and 26 (3.2%) were off medication. The sociodemographic and clinical characteristics according to treatment groups are shown in table 1. Gender distribution was similar across groups. A high prevalence of women, Caucasians, non-smokers, acute cutaneous lupus and arthritis was found in all groups. Patients in group 1 had lower disease activity measured by SLEDAI, less organ damage measured by SLICC and lower physician's global assessment. In group 2 patients were younger and had higher prevalence of renal involvement. Patients in group 3 had higher SLEDAI score and damage, higher prevalence of mucocutaneous, articular, neurologic and hematologic involvement and more use of glucocorticoids. Conclusions: Almost all SLE patient with established disease were chronically medicated, most with antimalarials and/or glucocorticoids. As expected, group 1 had less severe disease. Patients under immunosuppressants had a higher frequency of renal involvement, which denotes a targeted therapeutic strategy. In routine clinical settings biologics are rarely used, being restricted to patients with very active SLE and multiple clinical manifestations.
