Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose: TURKBIO is the Turkish version of Danish DANBIO rheumatologic database which has been established in 2011.In 2016,the EULAR RA management guideline recommended assessment of certain prognostic factors while deciding the treatment strategy after the first csDMARD failure.However, it is unknown how frequent these factors are in bDMARD and tsDMARD initiators and how they affect the treatment response in RA patients.We examined the frequency and influence of these poor prognostic factors on treatment response in bDMARD and tsDMARD initiating RA patients enrolled in TURKBIO.Methods: Seven poor prognostic factors were investigated in 898 RA patients started bDMARD and tsDMARD in TURKBIO:(1)Moderate to high disease activity(2)Elevated acute phase reactants(3)High swollen joint counts(≥4)(4)High RF/ACPA titers(5)Combinations of the above(6)Erosions(7)Failure of ≥2 csDMARDs.The frequencies of these factors at treatment initiation and influence of these on achievement of DAS28-CRP remission/remission+low disease activity(LDA) at the 6th month of treatment were evaluated in overall any bDMARD and tsDMARD-receiving RA patients and in subgroups of individual drugs including TNFinhibitors(TNFi),abatacept(ABA),rituximab(RTX),tocilizumab(TCZ)and tofacitinib(TOFA).The presence of these factors in patients who stayed on or were withdrawn from the bDMARDs and tsDMARD were also determined.Results: Among the seven prognostic factors; factors 1, 2, 4, 6 and 7 were found in over 60% of patients while factors 3 and 5 were present in about 30% of the patients.Factors 1 and 3 were more frequent in patients who were in moderate/high disease activity compared to those in remission+low disease activity at the 6th month of treatment(Table).Similarly factors1 and 3 were determined at higher percentage in non-remission than remission group(Factor 1: 93.4% vs. 82.2%, p<0.001; factor 3: 43% vs. 30.7%, p=0.002).These two factors were also significantly more frequent in patients withdrawn from the treatment than in patients who stayed on treatment(Factor 1: 93% vs. 85%, p<0.001; factor 3: 41% vs. 34%, p=0.038).In TNFi group besides factors 1 and 3, factors 5 and 7 were also significantly more frequent in non-remission group than in remission group whereas, in the RTX group, only factor 1 was significantly more frequent in remission group compared to in non-remission group. For the other bDMARDs and ts DMARD we did not find any difference in poor prognostic factors among patients who did achieve remission and did not.Conclusion: Five of the seven poor prognostic factors were detected more than half of the RA patients at bDMARD and tsDMARD initiation in TURKBIO.Patients with poor prognostic factors especially factors 1 and 3 achieved remission less frequently.Additionally, there was a relationship between bDMARDs and tsDMARD withdrawal and factors 1 and 3.The influence of these factors was mainly observed in TNFi receiving group.
