RESUMEN
To characterize disease activity trajectories and compare long-term drug retention between rheumatoid (RA) and spondylarthritis (SpA) patients initiating tumor necrosis factor inhibitor (TNFi) treatment (etanercept). Prospective observational study of RA, axial (AxSpA) and peripheral SpA (PerSpA) patients initiating etanercept during 2004-2020. Kaplan-Meier plots were used for drug retention comparisons and multivariable Cox regression models for predictors of discontinuation. Long-term disease activity trajectories were identified by latent class growth models using DAS28-ESR or ASDAS-CRP as outcome for RA and AxSpA respectively. We assessed 711 patients (450 RA, 178 AxSpA and 83 PerSpA) with a median (IQR) follow-up of 12 (5-32) months. At 5 years, 22%, 30% and 21% of RA, AxSpA and PerSpA patients, respectively, remained on therapy. Etanercept discontinuation was independent of the diagnosis and was predicted by gender and obesity in both RA and SpA groups. Four disease activity (DA) trajectories were identified from 6th month of treatment in both RA and AxSpA. RA patients in remission-low DA groups (33.7%) were younger, had shorter disease duration, fewer comorbidities and lower baseline disease activity compared to moderate (40.6%) & high DA (25.7%) groups. In AxSpA 74% were in inactive-low DA and they were more often males, non-obese and had lower number of comorbidities compared to higher ASDAS-CRP trajectories. In RA and AxSpA patients, disease activity trajectories revealed heterogeneity of TNFi treatment responses and prognosis. Male gender, lower baseline disease activity and fewer comorbidities, characterize a favourable outcome in terms of disease burden accrual and TNFi survival.

OBJECTIVES: Early arthritis clinics (EAC) aim to improve rheumatoid arthritis (RA) outcomes by tailoring treatment targeting to remission. Our aim was to analyse disease course and relevant predictors over 2 years in early arthritis; we also assessed the applicability of the "treat-to-target approach" in a real-life EAC. METHODS: Patients with early arthritis recruited at the EAC of the University Hospital of Heraklion were followed prospectively according to a follow-up protocol for two years, without implementing a pre-specified treatment protocol, to capture real-life practices. Early predictors of "suboptimal outcomes" (high disease activity or HAQ>1.0 at 2 years) and biologic DMARD (bDMARD) initiation were evaluated with multivariate logistic regression. Intensification of treatment at 3 and 6 months and subsequent long-term outcome were also assessed. RESULTS: 251 patients [RA (n=188), undifferentiated arthritis (n=63)] were included. Although both DAS28 and HAQ at 2 years improved significantly compared to baseline in RA patients [mean (SD) DAS28 and median (IQR) HAQ 3.70 (1.32) and 0.44 (0.75) at 2 years, p<0.001 for both compared to baseline], 43.7% still had moderate and 18.8% high disease activity. The most powerful predictor of suboptimal outcomes or bDMARD initiation in RA was high disease activity at three months (adjusted odds ratio 2.22 and 2.62, respectively). At three and six months 72.8% and 62.4% of patients with medium/high disease activity received treatment intensification, which resulted in significant decrease in disease activity at 2 years (p<0.001 for ΔDAS28). CONCLUSIONS: DAS28 at three months was the most powerful predictor of suboptimal disease outcome during a 2-year follow-up in early RA. Despite significant DAS reductions, more than 50% of patients have active disease at two years. Failure to fully implement the treat-to-target strategy in our cohort could account for the low remission rates.

New biologic and small molecule targeted agents have expanded the armamentarium of Spondyloarthritides (SpA), allowing more therapeutic options for patients who do not respond to therapy. The implementation of the treat-to-target (T2T) strategy with close monitoring and frequent treatment adaptations targeting disease remission has been proposed as the means to prevent radiographic progression and long-term adverse outcomes. In this project we will employ the "University of Crete Rheumatology Clinic Registry" to prospectively study in real-world practice musculoskeletal and extraarticular disease activity, patient function, comorbidities, sociodemographics, imaging, compliance to therapy and other lifestyle factors in axial and peripheral SpA patients. The predictive value of these variables in long-term (2years) outcomes will be evaluated. We will also assess the implementation of the T2T approach as well as its impact on long-term patients' outcomes (quality of life, productivity, adverse events). The successful completion of this study could pave the way for improved and personalized therapy in patients with SpA.
