MethodsA single centre retrospective study was performed including RA patients who had initiated treatment with Baricitinib or Tofacitinib from September-2017 to January-2020. Demographic, clinical, laboratory, efficacy and safety variables were collected from baseline and at months 1, 3, 6, 12, 18 and 24. Effectiveness was evaluated by changes from the baseline in DAS28, SDAI, HAQ and acute phase reactants. Safety analysis included adverse events due to any cause, including infection or intolerance. Infection was considered severe if it implied hospitalization. Statistical analysis consisted in Bayesian mixed ordinal regression models including the monotonic effect of each visit and Kaplan–Meier survival curves. ResultsOverall, 98 patients were included. A significant reduction of disease activity scores was noted in both groups. No difference between either treatment was detected in terms of effectiveness even in first line, after bDMARD failure, in monotherapy nor combined therapy. A total of 54 adverse events were recorded of which 18 were considered relevant. The incidence of infection, including Herpes Zoster, was similar in both groups. No patients in either group suffered any tuberculosis, thromboembolic event, malignancy, death or cardiovascular adverse events.Survival analysis did not show any difference between groups. ConclusionBaricitinib and Tofacitinib are both comparable in terms of effectiveness and safety in real world conditions. ER -
