RESUMEN
OBJECTIVES: Anti-SSA autoantibodies can be differentiated according to their antigenic target proteins as anti-Ro60 (60 kDa) or anti-Ro52 (52 kDa). Anti-SSA(Ro60) antibodies are clearly associated with connective tissue diseases (CTD), but the clinical significance of anti-SSA(Ro52) antibodies remains unclear. The aim of the present study was to analyse the disease phenotype of patients with anti-Ro52 and/or anti-Ro60 antibodies. METHODS: A multicentre, cross-sectional study was carried out of positive anti-Ro52 and/or Ro60 antibodies patients followed at 10 Rheumatology centres from January 2018 until December 2021. Patients were categorised into 3 groups: group 1 (Ro52+/Ro60-); group 2 (Ro52-/Ro60+); group 3 (Ro52+/Ro60+). Antinuclear antibodies were evaluated by indirect immunofluorescence assay and further screened for anti-extractable nuclear antigen (ENA) antibodies. Demographicsand clinical data were compared between the 3 groups, by patients' medical chart review. Univariate analysis was performed and subsequently logistic regression was used to identify intergroup differences and calculate the odds ratio with a 95% confidence interval (95% CI). RESULTS: We included 776 patients [female: 83.1%; median age: 59 (46-71) years]. Groups 1, 2, and 3 comprised 31.1%, 32.6%, and 36.3% of the patients, respectively. Anti-Ro52 antibody alone was more frequently associated with non-rheumatic diseases, older age, and men (p<0.05). Among patients with CTD, the diagnosis of systemic lupus erythematosus is 3 and 2 times more prevalent in groups 2 and 3, respectively, than in group 1 [OR 2.8 (95% CI 1.60, 4.97), p<0.001; OR 2.2 (95% CI 1.28, 3.86), p<0.01]. In group 2, the diagnosis of undifferentiated CTD is more frequent than in the other groups. Group 1 was more frequently associated with inflammatory myositis than group 2 [OR 0.09 (95% CI 0.01, 0.33), p<0.001] or group 3 [OR 0.08 (95% CI 0.01, 0.29), p<0.001]. Group 1 was also more frequently associated with arthritis (p<0.01), interstitial lung disease (p<0.01), and myositis (p<0.01). CONCLUSIONS: Anti-Ro52+ antibody alone is frequently found in patients with non-rheumatic diseases. In addition, anti-Ro52+ antibody is also prevalent in patients with CTD and associated with clinical phenotypes that are different from anti-Ro60+ antibody.

PURPOSE: To evaluate two-year mortality predictors in all subtypes of fragility fractures. METHODS: Medical records review, single-center study with Portuguese patients with fragility fractures; A univariate analysis, with chi-square for categorical variables and parametric t-student and non-parametric Wilcoxon tests for continuous variables, was performed. Posteriorly, a survival analysis, with subsequent Cox regression was conducted to establish independent risk factors/ predictors of two-year mortality in fragility fractures. RESULTS: 758 patients were enrolled in the study. We found a total of 151 deaths within the first two years post-fracture. On Cox regression, older age [OR1.10 CI (1.05-1.11)], male sex [OR1.85 CI(1.24-2.75)], anemia at baseline [OR2.44 CI(1.67-3.57)], malignancy [OR4.68 CI (2.13-10.27)], and multimorbidity [OR1.78 CI(1.11-2.87)] were found as independent predictors for two-year post-fracture mortality. CONCLUSION: Our study suggests that male sex, older age, anemia, malignancy, and multimorbidity are mortality predictors in the first two years after fragility fractures, reinforcing the importance of comorbidity management in preventing or, at least, minimizing adverse outcomes following fragility fractures.

Background: Obesity has been extensively studied over the years, primarily focusing on the physiological aspects of the disease. However, the general burden of obesity mainly the financial implications and its influence on hospitalization and length of stay have only recently garnered attention in the literature, particularly in the case of Portugal. Aim: This study aimed to investigate the association between obesity and hospitalizations in the Portuguese adult population and compare the average costs of hospitalization among participants with and without obesity. Methods: At baseline, the analytic sample consisted of 10,102 participants aged ≥18 years from the Portuguese population-based Epidemiology of Chronic Diseases Cohort (EpiDoC). Participants were then followed for up to 10 years from 2011 to 2021 in three more waves of data collection. Body mass index was derived from self-reported weight and height, and instances of hospitalization were self-reported by the participants. The associated costs for each hospitalization episode were categorized according to national legislation and valued according to the pricing for Diagnosis Related Groups. Results: Obesity was associated with more hospitalizations (for example, Obesity class I vs. normal weight: OR = 1.33 [1.14-1.55]). However, when the presence of multimorbidity was considered, this association diminished. While longer hospital length of stay was observed in individuals with higher obesity categories, this difference did not reach statistical significance. On average, the total hospitalization costs per patient with obesity amounted to 200.4 per year. Conclusion: Obesity is as a risk factor for hospitalizations and potentially with higher length of stay hospitalizations, with this effect being partially mediated by the concurrent presence of multimorbidity. Consequently, obesity constitutes an additional burden on healthcare systems. This underscores the imperative of implementing cost-effective prevention programs aimed at addressing and managing this significant public health concern.

OBJECTIVE: To investigate real-world retention and remission rates in PsA patients initiating a 2nd or 3rd TNFi and the association with reason for discontinuation from the previous TNFi-treatment. METHODS: Prospectively collected routine care data from 12 European registries were pooled. Retention rates (Kaplan-Meier estimation) and crude/LUNDEX-adjusted rates of Disease Activity Score 28 and Disease Activity index for PSoriatic Arthritis (DAS28 and DAPSA28) remission were calculated and compared with adjusted Cox regression analyses and Chi-squared test, respectively). RESULTS: We included 5233 (2nd TNFi) and 1906 (3rd TNFi) patients. Twelve-month retention rates for the 2nd and 3rd TNFi were 68% (95%CI: 67-70%) and 66% (64-68%), respectively. Patients who stopped the previous TNFi due to AE/LOE had 12-month retention rates of 66%/65% (2nd TNFi), and 65%/63% (3rd TNFi), respectively. Patients who stopped the previous TNFi due to LOE after less vs more than 24 weeks had 12-month retention rates of 54%/69% (2nd TNFi), and 58%/65% (3rd TNFi). Six-month crude/LUNDEX-adjusted DAS28 remission rates were 48%/35% and 38%/27%, and DAPSA28 remission rates were 19%/14% and 14%/10%, for the 2nd and 3rd TNFi. CONCLUSION: Two-thirds of patients remained on TNFi at 12months for both the 2nd and 3rd TNFi, while one-third and one-quarter of patients were in DAS28 remission after 6months on the 2nd and 3rd TNFi. While drug effectiveness was similar in patients who stopped the previous TNFi due to AE compared to overall LOE, drug effectiveness was better in patients who had stopped the previous TNF due to secondary LOE compared to primary LOE.

OBJECTIVES: To compare the treatment effectiveness of secukinumab in radiographic (r) versus non-radiographic (nr) axial spondyloarthritis (axSpA) patients treated in routine care across Europe. METHODS: Prospectively collected data on secukinumab-treated axSpA patients with known radiographic status were pooled from nine countries.Remission rates based on patient-reported outcomes (PROs; Numeric Rating Scale (0-10), for example, pain ≤2/Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≤2 and Ankylosing Spondylitis Disease Activity Score (ASDAS) inactive disease (ID) <1.3 after 6/12/24 months of secukinumab treatment were calculated.Remission and drug retention rates in r-axSpA versus nr-axSpA patients were compared by logistic and Cox regression models (unadjusted/adjusted for age+sex/adjusted for multiple confounders). RESULTS: Overall, 1161 secukinumab-treated patients were included (r-axSpA/nr-axSpA: 922/239). At baseline, r-axSpA patients had longer disease duration and higher C reactive protein, were more often male and HLA-B27 positive and had received fewer prior biological or targeted synthetic disease-modifying antirheumatic drugs compared with nr-axSpA patients, whereas PROs were largely similar.During follow-up, crude PRO remission rates were significantly higher in r-axSpA compared with nr-axSpA patients (6 months: pain≤2: 40%/28%, OR=1.7; BASDAI≤2: 37%/25%, OR=1.8), as were drug retention rates (24 months: 66%/58%, HR 0.73 (ref: r-axSpA)). Proportions of patients achieving ASDAS ID were low for both groups, particularly nr-axSpA (6 months: 11%/8%).However, when adjusting for age+sex, these differences diminished, and after adjusting for multiple confounders, no significant between-group differences remained for either remission or drug retention rates. CONCLUSION: Crude remission/drug retention rates in European secukinumab-treated patients were higher in r-axSpA compared with nr-axSpA patients. In adjusted analyses, secukinumab effectiveness was similar in both groups, suggesting that observed differences were related to factors other than radiographic status.

RESUMEN
Despite the establishment of Fracture Liaison Services (FLS) worldwide, no study has evaluated their impact on the Portuguese population. Our work has shown that the implementation of an FLS is associated with a significant increase in OP treatment and a lower risk of secondary fracture. PURPOSE: Fracture Liaison Services (FLS) have been established worldwide, with positive effects on treatment, secondary fracture, mortality, and economic burden. However, no study has evaluated their impact on the Portuguese population. Therefore, we purposed to evaluate the effect of an FLS model in a Portuguese center on osteoporosis (OP) treatment, secondary fracture, and mortality rates, 3 years after a fragility fracture. METHODS: Patients over 50 years old, admitted with a fragility fracture, between January 2017 and December 2020, were included in this retrospective study. Patients evaluated after FLS implementation (2019-2020) were compared with those evaluated before (2017-2018) and followed for 36 months. Predictors of secondary fracture and mortality were assessed using a multivariate Cox regression model, adjusted to potential confounders. RESULTS: A total of 551 patients were included (346 before and 205 after FLS). The FLS significantly increased the rate of OP treatment, when compared with standard clinical practice (8.1% vs 77.6%). During follow-up, the secondary fracture rate was 14.7% and 7.3%, before and after FLS, respectively. FLS was associated with a lower risk of secondary fracture (HR 0.39, C.I. 0.16-0.92). Although we observed a lower mortality rate (25.1% vs 13.7%), FLS was not a significant predictor of survival. CONCLUSION: Implementing the FLS model in a Portuguese center has increased OP treatment and reduced the risk of secondary fracture. We believe that our work supports adopting FLS models in national programs.

Socio-demographic variations may influence spondyloarthropaties (SpAs) clinical and laboratorial characteristics and prognosis. In the Portuguese population the information available related with this disease is scarce Objective. To characterize demographic, clinical and laboratory features of SpAs patients in Portugal. Patients and methods. Patients followed at four participating Rheumatology Departments with the diagnosis of SpA were enrolled. Results. 110 patients were included, 58.4% were males, essentially Caucasian with an average age of 46.5 years. The most frequent clinical feature was inflammatory back pain (63.4%) and acute anterior uveitis was the most common extra-articular manifestation. The predominant type of SpAs found was Ankylosing Spondylitis (AS). Conclusions. Patients with AS presented clinical features similar to those observed in other populations, except for tarsitis (AU)
