RESUMO
OBJECTIVES: To compare proliferative (PLN) and membranous (MLN) lupus nephritis (LN) regarding clinical and laboratory presentation and long-term outcomes; To investigate predictors of progression to chronic kidney disease (CKD). METHODS: Multicentre observational study, with retrospective analysis of a prospective cohort, using data from the Rheumatic Diseases Portuguese Registry-Reuma.pt. Patients with biopsy-proven PLN, MLN and mixed LN were included. Cox regression survival analysis was used to investigate predictors of CKD. RESULTS: 260 patients were included. Median follow-up was 8 years (IQR 11; minimum 1, maximum 35 years). MLN patients presented with significantly lower serum creatinine (0.70 (IQR 0.20; minimum 0.50, maximum 1.30) mg/dl vs 0.80 (IQR 0.31; minimum 0.26, maximum 2.60) in PLN, p= 0.003). Proteinuria levels did not differ between groups (p= 0.641). Levels of complement were reduced in PLN but nearly normal in MLN patients, and there were fewer patients with positive anti-dsDNA antibodies in the MLN group (p< 0.001). One year after the beginning of treatment, 62% of the patients achieved EULAR/ERA-EDTA complete response, with further 5% achieving partial response. Patients with lower proteinuria at diagnosis were more likely to achieve a complete renal response at one year, however, proteinuria at diagnosis or at one year did not predict long term CKD. Estimated glomerular filtration rate (eGFR) ≤75 mL/min/1.73 m2 at one year was the strongest predictor of progression to CKD (HR 23 [95% CI 8-62], p< 0.001). Other possible predictors included the use of azathioprine for induction of remission, older age at diagnosis and male sex. CONCLUSION: Proteinuria levels did not predict LN histologic class in our cohort. eGFR cutoff of 75 mL/min/1.73 m2 after one year of treatment was strongly predictive of progression to CKD.
RESUMO
OBJECTIVES: Patient centred care is an increasingly important paradigm. Applying a treat-to-target strategy to the impact of the disease in patients' lives seems a very promising tool to serve this purpose. We aimed to evaluate if maximum acceptable impact scores (target-values) defined at the population level provide an appropriate representation for most individual patients. To determine if the individually established target values of impact are consistent enough to be used in a treat-to-target strategy. METHODS: Consecutive patients with rheumatoid arthritis were asked to indicate, in two consecutive visits, the maximum severity of impact they considered acceptable to live with for the rest of their lives, in the seven domains of Rheumatoid Arthritis Impact of Disease score. The individual adequacy of population-based reference values was assessed by measures of dispersion. Stability of individual target-values were evaluated through intraclass correlation coefficient. Socio-demographic, clinical and psychological features were tested as co-factors of stability. RESULTS: 299 patients were included. The dispersion of targets was wide (CV>0.68), thus limiting the use of any population-based single values as targets for the individual patients. Although the mean target values were very similar in both visits for all domains, reliability was poor in all cases (ICCs: 0.37-0.47). Only 25-30% of the patients selected the same target value in the 2 visits. No explanatory factors for (non-)stability were identified. CONCLUSIONS: Quantified impact targets defined at population level are not appropriate for individual patient care. Research on alternative tools to support patient-centred, target-oriented management strategies is warranted.

(1) Background: The UCLA GIT 2.0 questionnaire has been recognized as a feasible and reliable instrument to assess gastrointestinal (GI) symptoms in systemic sclerosis (SSc) patients and their impact on quality of life. The aim of this study was to create and validate UCLA GIT 2.0 for Portuguese patients with SSc. (2) Methods: A multi-center study was conducted enrolling SSc patients. UCLA GIT 2.0 was validated in Portuguese using reliability (internal consistency, item -total correlation, and reproducibility) and validity (content, construct, and criterion) tests. Criterion tests included EQ-5D and SF-36v2. Social-demographic and clinical data were collected. (3) Results: 102 SSc patients were included, 82.4% of them female, and with a mean sample age of 57.0 ± 12.5 years old. The limited form of SSc was present in 62% of the patients and 56.9% had fewer than five years of disease duration. Almost 60% presented with SSc-GI involvement with a negative impact on quality of life. The means for SF-36v2 were 39.3 ± 10.3 in the physical component summary and 47.5 ± 12.1 in the mental component summary. Total GI score, reported as mild in 57.8% of the patients, was highly reliable (ICC = 0.912) and the Cronbach's alpha was 0.954. There was a high correlation between the total GI score and EQ-5D-5L and SF-36v2 scores. (4) Conclusion: The Portuguese version of UCLA GIT 2.0 showed good psychometric properties and can be used in research and clinical practice.

The Health Assessment Questionnaire Disability Index (HAQ-DI) was completed with five visual analog scales to assess systemic sclerosis (SSc) called Scleroderma HAQ (SHAQ). We performed a validation of the European Portuguese version of SHAQ for patients with SSc. Patients with different forms of SSc from five Hospital Centers were invited. The reliability of the Portuguese SHAQ was evaluated by internal consistency and by test-retest reliability. Content validity was checked by two rheumatologists and by a panel of patients. Construct validity was assessed by structural validity and by known-groups hypothesis tests. Criterion validity was addressed with selected dimensions from the UCLA GIT 2.0, the SF-36v2, and the EuroQoL EQ-5D-5L. A total of 102 SSc patients agreed to participate, 31 of which answered to the retest. HAQ-DI demonstrated high internal consistency reliability (α = 0.866) and SHAQ also showed high test-retest reliability (ICC 0.61-0.95). We evidenced the unidimensionality of all VASs. HAQ-DI scores were worse in males, patients older than 65 years, and individuals with a diffuse form of SSc. Criterion validity was mainly evidenced through the correlation between the HAQ-DI and SF-36v2 physical summary measure (r = -0.688) and EQ-5D-5L index score (r = -0.723). Likewise, the SHAQ overall disease severity VAS was also correlated with SF-36v2 physical summary measure (r = -0.628). Mental score correlations were smaller. With the exception of the Raynaud's VAS, all the other VASs correlated well with similar clinical variables. This paper provides evidence to demonstrate how reliable and valid the European Portuguese version of SHAQ is, to be used in SSc patients to assess the clinical severity under the perspective of patients.

OBJECTIVES: To compare the effectiveness of the infliximab biosimilar CT-P13 with originator infliximab over 24 months of follow-up in biological-naïve patients with rheumatoid arthritis (RA) and axial spondyloarthritis (axSpA). METHODS: Biological-naïve patients from the Rheumatic Diseases Portuguese Register (Reuma.pt), with a clinical diagnosis of RA or axSpA, who were starting either the infliximab biosimilar CT-P13 or the originator infliximab after 2014 (date of market entry of CT-P13 in Portugal), were included. Patients on biosimilar and originator were compared regarding different response outcomes at 3 and 6 months, adjusting for age, sex and baseline C-reactive protein (CRP). The main outcome was the change in DAS28-erytrocyte sedimentation rate (ESR) for RA and the ASDAS-CRP for axSpA. Additionally, the effect of infliximab biosimilar vs originator on different response outcomes over 24 months of follow-up was tested with longitudinal generalized estimating equations (GEE) models. RESULTS: In total, 140 patients were included, 66 (47%) of which with RA. The distribution of patients starting the infliximab biosimilar and the originator was the same between the two diseases (approximately 60% and 40%, respectively). From the 66 patients with RA, 82% were females, mean age was 56 years (SD 11) and mean DAS28-ESR 4.9 (1.3) at baseline. As for the patients with axSpA, 53% were males, mean age was 46 years (13) and mean ASDAS-CRP 3.7 (0.9) at baseline. There were no differences in efficacy between RA patients treated with the infliximab biosimilar and the originator, either at 3 months (∆DAS28-ESR: -0.6 (95% CI -1.3; 0.1) vs -1.2 (-2.0; -0.4)), or at 6 months (∆DAS28-ESR: -0.7 (-1.5; 0.0) vs -1.5 (-2.4; -0.7)). This was also true for patients with axSpA (∆ASDAS-CRP at 3 months: -1.6 (-2.0; -1.1) vs -1.4 (-1.8; -0.9) and at 6 months: -1.5 (-2.0; -1.1) vs -1.1 (-1.5; -0.7)). Results were similar with the longitudinal models over 24 months. CONCLUSION: There are no differences in effectiveness between the infliximab biosimilar CT-P13 and the infliximab originator in the treatment of biological-naïve patients with active RA and axSpA in clinical practice.

Objectives: Idiopathic inflammatory myopathies (IIM) are a group of rare disorders that can affect the heart. This work aimed to find predictors of cardiac involvement in IIM. Methods: Multicenter, open cohort study, including patients registered in the IIM module of the Rheumatic Diseases Portuguese Register (Reuma.pt/Myositis) until January 2022. Patients without cardiac involvement information were excluded. Myo(peri)carditis, dilated cardiomyopathy, conduction abnormalities, and/or premature coronary artery disease were considered. Results: 230 patients were included, 163 (70.9%) of whom were females. Thirteen patients (5.7%) had cardiac involvement. Compared with IIM patients without cardiac involvement, these patients had a lower bilateral manual muscle testing score (MMT) at the peak of muscle weakness [108.0 ± 55.0 vs 147.5 ± 22.0, p=0.008] and more frequently had oesophageal [6/12 (50.0%) vs 33/207 (15.9%), p=0.009] and lung [10/13 (76.9%) vs 68/216 (31.5%), p=0.001] involvements. Anti-SRP antibodies were more commonly identified in patients with cardiac involvement [3/11 (27.3%) vs 9/174 (5.2%), p=0.026]. In the multivariate analysis, positivity for anti-SRP antibodies (OR 104.3, 95% CI: 2.5-4277.8, p=0.014) was a predictor of cardiac involvement, regardless of sex, ethnicity, age at diagnosis, and lung involvement. Sensitivity analysis confirmed these results. Conclusion: Anti-SRP antibodies were predictors of cardiac involvement in our cohort of IIM patients, irrespective of demographical characteristics and lung involvement. We suggest considering frequent screening for heart involvement in anti-SRP-positive IIM patients.

AIMS: To characterise the idiopathic inflammatory myopathies (IIM) module of the Rheumatic Diseases Portuguese Register (Reuma.pt/myositis) and the patients in its cohort. METHODS: Reuma.pt is a web-based system with standardised patient files gathered in a registry. This was a multicentre open cohort study, including patients registered in Reuma.pt/myositis up to January 2022. RESULTS: Reuma.pt/myositis was designed to record all relevant data in clinical practice and includes disease-specific diagnosis and classification criteria, clinical manifestations, immunological data, and disease activity scores. Two hundred eighty patients were included, 71.4% female, 89.4% Caucasian, with a median age at diagnosis and disease duration of 48.9 (33.6-59.3) and 5.3 (3.0-9.8) years. Patients were classified as having definite (N=57/118, 48.3%), likely (N=23/118, 19.5%), or possible (N=2/118, 1.7%) IIM by 2017 EULAR/ACR criteria. The most common disease subtypes were dermatomyositis (DM, N=122/280, 43.6%), polymyositis (N=59/280, 21.1%), and myositis in overlap syndromes (N=41/280, 14.6%). The most common symptoms were proximal muscle weakness (N=180/215, 83.7%) and arthralgia (N=127/249, 52.9%), and the most common clinical signs were Gottron's sign (N=75/184, 40.8%) and heliotrope rash (N=101/252, 40.1%). Organ involvement included lung (N=78/230, 33.9%) and heart (N=11/229, 4.8%) involvements. Most patients expressed myositis-specific (MSA, N=158/242, 65.3%) or myositis-associated (MAA, 112/242, 46.3%) antibodies. The most frequent were anti-SSA/SSB (N=70/231, 30.3%), anti-Jo1 (N=56/236, 23.7%), and anti-Mi2 (N=31/212, 14.6%). Most patients had a myopathic pattern on electromyogram (N=101/138, 73.2%), muscle oedema in magnetic resonance (N=33/62, 53.2%), and high CK (N=154/200, 55.0%) and aldolase levels (N=74/135, 54.8%). Cancer was found in 11/127 patients (8.7%), most commonly breast cancer (N=3/11, 27.3%). Most patients with cancer-associated myositis had DM (N=8/11, 72.7%) and expressed MSA (N=6/11) and/or MAA (N=3/11). The most used drugs were glucocorticoids (N=201/280, 71.8%), methotrexate (N=117/280, 41.8%), hydroxychloroquine (N=87/280, 31.1%), azathioprine (N=85/280, 30.4%), and mycophenolate mofetil (N=56/280, 20.0%). At the last follow-up, there was a median MMT8 of 150 (142-150), modified DAS skin of 0 (0-1), global VAS of 10 (0-50) mm, and HAQ of 0.125 (0.000-1.125). CONCLUSIONS: Reuma.pt/myositis adequately captures the main features of inflammatory myopathies' patients, depicting, in this first report, a heterogeneous population with frequent muscle, joint, skin, and lung involvements.
RESUMO
INTRODUCTION/OBJECTIVES: The study aims to define the clinical and subclinical calcinosis prevalence, the sensitivity of radiographed site and clinical method for its diagnosis, and the phenotype of Portuguese systemic sclerosis (SSc) patients with calcinosis. METHOD: A cross-sectional multicenter study was conducted with SSc patients fulfilling Leroy/Medsger 2001 or ACR/EULAR 2013 classification criteria, registered in the Reuma.pt. Calcinosis was assessed through clinical examination and radiographs of hands, elbows, knees, and feet. Independent parametric or non-parametric tests, multivariate logistic regression, and sensitivity calculation of radiographed site and clinical method for calcinosis detection were performed. RESULTS: We included 226 patients. Clinical calcinosis was described in 63 (28.1%) and radiological calcinosis in 91 (40.3%) patients, of which 37 (40.7%) were subclinical. The most sensitive location to detect calcinosis was the hand (74.7%). Sensitivity of the clinical method was 58.2%. Calcinosis patients were more often female (p = 0.008) and older (p < 0.001) and had more frequently longer disease duration (p < 0.001), limited SSc (p = 0.017), telangiectasia (p = 0.039), digital ulcers (p = 0.001), esophageal (p < 0.001) and intestinal (p = 0.003) involvements, osteoporosis (p = 0.028), and late capillaroscopic pattern (p < 0.001). In multivariate analysis, digital ulcers (OR 2.63, 95% CI 1.02-6.78, p = 0.045) predicted overall calcinosis, esophageal involvement (OR 3.52, 95% CI 1.28-9.67, p = 0.015) and osteoporosis (OR 4.1, 95% CI 1.2-14.2, p = 0.027) predicted hand calcinosis, and late capillaroscopic pattern (OR 7.6, 95% CI 1.7-34.9, p = 0.009) predicted knee calcinosis. Anti-nuclear antibody positivity was associated with less knee calcinosis (OR 0.021, 95% CI 0.001-0477, p = 0.015). CONCLUSIONS: Subclinical calcinosis high prevalence suggests that calcinosis is underdiagnosed and radiographic screening might be relevant. Multifactorial pathogenesis may explain calcinosis predictors' variability. Key Points ⢠Prevalence of subclinical calcinosis in SSc patients is substantial. ⢠Hand radiographs are more sensitive to detect calcinosis than other locations or clinical method. ⢠Digital ulcers were associated with overall calcinosis, esophageal involvement and osteoporosis were associated with hand calcinosis, and late sclerodermic pattern in nailfold capillaroscopy was associated with knee calcinosis. ⢠Anti-nuclear antibody positivity may be a protective factor for knee calcinosis.

With the purpose of contributing to a better knowledge of the APCs functional activity in SLE, we evaluated the distribution and functional ability to produce pro-inflammatory cytokines (TNF-α, IL-1ß, IL-6 and IL-12) of peripheral blood (PB) monocytes and DC (tDC), particularly myeloid (mDC) and CD14(-/low)CD16(+) DC subpopulations comparing them with those obtained from healthy individuals. The study was performed in 34 SLE patients with diverse disease activity scores (SLEDAI) and 13 healthy age- and sex-matched controls (NC). Our results show an overall decrease in absolute number and relative frequency of tDC in SLE patients with active disease when compared to those with inactive disease and NC, although this decrease did not seem to have an effect on the distribution of PB DC subsets. The monocytes number in SLE patients was similar to those found in NC, whereas a higher frequency of monocytes producing cytokines as well as the amount of each cytokine per cell found without stimulation was particularly observed in those patients with active disease. After stimulation, we observed a higher frequency of IL-12-producing monocytes in active SLE patients. On the other hand, we found among DCs higher frequencies of cytokine-producing CD14(-/low)CD16(+) DCs and a higher amount of cytokines produced per cell, particularly in active disease. These findings support an increased production of inflammatory cytokines by APCs in active SLE, mostly associated with alterations in CD14(-/low)CD16(+) DC subset homeostasis that might contribute to explain the dynamic role of these cells in disease pathogenesis.

OBJECTIVES: To estimate the relationship between EQ5D (three levels, UK version) and the Ankylosing Spondylitis Disease Activity Score (ASDAS) for use in the economic evaluation of health technologies for people with axial spondyloarthritis (axSpA). To compare against the relationship with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). METHODS: An electronic, prospective, Portuguese, nationwide, rheumatic disease register (Reuma.pt) provided data on 1140 patients (5483 observations) with a confirmed diagnosis of axSpA. We estimated models of EQ5D as a function of ASDAS, alone or in combination with measures of functional impairment, using bespoke mixture models which reflect the complex distributional features of EQ5D. The SPondyloArthritis Caught Early cohort provided data from 344 patients (1405 observations) in four European countries and was used for validation. A previously published model of BASDAI/Bath Ankylosing Spondylitis Functional Index (BASFI) was also used to generate predicted EQ5D scores and model performance compared. RESULTS: A non-linear relationship exists between EQ5D from ASDAS. The final model included ASDAS, ASDAS squared, age and age squared and demonstrated close fit in both datasets except where data were sparse for patients with very high levels of disease activity (ASDAS >4). This finding held in the validation dataset. Models that included BASFI improved model fit. The ASDAS based models fit the data marginally less well than models using BASDAI. CONCLUSIONS: Mapping models linking ASDAS to EQ5D allow results from clinical studies to be used in economic evaluation of health technologies with confidence. There is some loss of information compared with BASDAI but this has only a marginal impact.

BACKGROUND: Axial spondyloarthritis (axSpA), particularly ankylosing spondylitis was historically considered a male's disease and has been under-recognized in women. Emerging evidence reveals sex differences in pathophysiology, disease presentation and therapeutic efficacy. OBJECTIVE: To identify differences between sexes in a Portuguese cohort of patients with axSpA regarding clinical manifestations, disease activity, functional capacity, patient related outcomes and presence of sacroiliitis on x-ray or magnetic resonance imaging. METHODS: Patients with ≥18 years fulfilling the ASAS- Assessment of Spondyloarthritis International Society classification criteria for axSpA registered in the electronic Rheumatic Diseases Portuguese Register (Reuma.pt) were included in this multicentric cross-sectional study. Sociodemographic data, clinical features and imaging were collected from the first record in Reuma.pt. These variables were compared between sexes using Mann-Whitney test and Chi-Square test. Variables with a significant association with variable sex were considered in the multiple variable analysis to adjust the sex effect on the outcome variables. Statistical analysis was performed with R version 4.0.2 and p <0.05 was considered statistically significant. RESULTS: A total of 1995 patients were included, 1114 (55.9%) men and 881 (44.1%) women. Men had an earlier disease onset (25.1 vs 28.4, p <0.001), were younger at diagnosis (26.9 vs 30.4, p<0.001) and were more frequently smokers (32.1% vs 15.7%, p <0.001). Comparing to women, men had worse Bath Ankylosing Spondylitis Metrological Index scores (4.0 vs 3.4, p<0.001), higher levels of C-Reactive Protein (10.5 vs 6.9 mg/L, p <0.001) and were more often Human Leukocyte Antigen-B27 positive (67.8% vs 54%, p <0.001). In contrast, women more frequently had inflammatory bowel disease (8.8% vs 4.9%, p =0.004), higher levels of erythrocyte sedimentation rate (25.0 vs 21.0mm/h, p=0.003) and worse patient-related outcomes- Bath Ankylosing Spondylitis Disease Activity Index (5.7 vs 4.5, p<0.001), Patient Global Assessment (60.0 vs 50.0, p <0.001) and fatigue (6.2 vs 5.0, p <0.001). DISCUSSION: In this large multicentric study from a Portuguese axSpA cohort, we confirmed sex differences in patients with axSpA. This work brings awareness to these differences, resulting in less underdiagnosis and misdiagnosis, optimizing treatment strategies, and improving outcomes in axSpA.

OBJECTIVE: To compare the effectiveness and safety of original (Enbrel®) and biosimilar (Benepali®) etanercept in Biologic Disease-modifying Antirheumatic Drug (bDMARD)-naïve patients, measured by persistence rates over 36 months of follow-up. METHODS: A retrospective multicentre observational study using data collected prospectively from The Rheumatic Diseases Portuguese Registry (Reuma.pt) was performed, including patients with: age ≥ 18 years old; diagnosis of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) or Spondyloarthritis (SpA) (axial or peripheral) with active disease and biologic-naïve who initiated treatment with etanercept as the first line biological treatment after 2010. Kaplan-Meyer and Cox regression were used to calculate the persistence rate in treatment. Disease activity at baseline and follow-up data at 6, 12, 18 and 24 months of treatment were compared. Causes for discontinuing therapy were summarized using descriptive statistics. Statistical significance was assumed for 2-sided p-values <0.05. RESULTS: We included 1693 patients (413 on Benepali® and 1280 on Enbrel®): 864 diagnosed with RA, 335 with PsA and 494 with SpA. The 3-year persistence rates were not significantly different between both treatment groups in RA, PsA and SpA patients. In the adjusted Cox model, hazard ratios of discontinuation were not statistically different (p>0.05). The proportion of subjects in remission or low disease activity in each disease was similar in both groups. Overall, 535 (31.6%) patients discontinued etanercept (428 patients on Enbrel® and 107 patients on Benepali®). The major cause of discontinuation was inefficacy (57.8%). No differences for the occurrence of inefficacy or adverse effects were found between treatment groups. CONCLUSIONS: Benepali® and Enbrel® demonstrated similar effectiveness and safety in RA, PsA and SpA in our cohort of patients. These data corroborate that the original and biosimilar drugs have similar quality characteristics and biological activity.

Evidence for the role of sex in the clinical manifestations of systemic sclerosis (SSc) patients is emerging. Some multicenter cohorts have shown that male SSc patients have more severe disease and worse survival. To assess the differences in clinical manifestations and survival in Portuguese SSc patients according to gender. Data from male and female adult SSc patients included in the Rheumatic Diseases Portuguese Register (Reuma.pt) were analysed and compared. Survival was calculated for patients included in Reuma.pt. within the first two years of diagnosis (inception cohort). In total, 1054 adult patients with SSc were included, 12.5% males. No differences in demographic features and comorbidities were found between the sexes, except for a higher rate of cigarette smokers among men. Diffuse cutaneous SSc and anti-topoisomerase antibodies were more prevalent in males than females. Additionally, male patients presented significantly more myositis, interstitial lung disease and gastric involvement. There were no differences in the patterns of drug use between the sexes. During follow-up, more deaths were reported in men than women (12.1% vs 7.3%, p = 0.04). The overall 1-, 3-, and 5-year survivals from diagnosis of the inception cohort (N = 469) for men vs women were 96.4% vs 98.2%, 93% vs 95.9%, and 75.8% vs 93.2%, respectively, with statistically significant differences (p < 0.01). This study confirms the existence of gender differences in clinical and immunological SSc features. Although SSc is less common in men than women, men have a more severe expression of skin and internal organ involvement and worse survival. Key Points ⢠There are differences in SSc disease manifestations between sexes. ⢠Males more commonly have diffuse cutaneous SSc, anti-topoisomerase antibodies, pulmonary and musculoskeletal involvement. ⢠In the inception cohort, men had worse survival rates than women.

BACKGROUND: Systemic sclerosis (SSc) is a rare connective tissue disorder with heterogeneous manifestations and outcomes. Besides differences in disease characteristics among distinct ethnic groups and geographical regions, several questions regarding the impact of the disease and the effectiveness of treatments remain unanswered. To address these questions, the Rheumatic Diseases Portuguese Register (Reuma.pt) launched a specific protocol for the prospective follow-up of SSc patients. OBJECTIVES: To describe the baseline characteristics, disease subsets, treatments used and survival of SSc patients registered in Reuma.pt/SSc. METHODS: Data from adult patients with SSc included in Reuma.pt up to November 2020 were analysed. Demographic features, SSc subsets, fulfilment of classification criteria, main clinical and immunological features, comorbidities, treatments used and survival data were described and compared between diffuse cutaneous (dc) and limited cutaneous (lc) disease subsets. Survival was calculated for patients included in Reuma.pt within the first two years of diagnosis. RESULTS: In total, 1054 patients were included, 87.5% female, with a mean age at diagnosis of 52.7 +/- 14.8 years. The most common subset was lcSSc (56.3%), followed by dcSSc (17.5%), preclinical SSc (13%), overlap syndrome (9.8%) and SSc sine scleroderma (3.3%). Raynaud's phenomenon (93.4%) and skin thickening (76.9%) were the most frequently observed clinical manifestations. Gastrointestinal (62.8% versus 47.8%), pulmonary (59.5% versus 23%) and cardiac (12.8% versus 6.9%) involvements were significantly more prevalent in dcSSc than lcSSc. Ninety per-cent of patients were Antinuclear antibody positive, 52.5% were Anti-centromere antibody positive and 21% anti-topoisomerase positive, with significant differences between lcSSc and dcSSc. One-third of patients were treated with immunomodulators, 53.6% with vasodilators, 23% with glucocorticoids and 2.3% with biologics. During follow-up, 83 deaths (7.9%) were reported. The overall 1-, 2- and 5-year survivals were 98.0%, 96.8% and 92.6%, respectively, without significant differences between lcSSc and dcSSc. CONCLUSION: Reuma.pt/SSc data highlights the importance of registries in improving knowledge about rare and complex diseases, such as SSc. Clinical features of Portuguese SSc patients are similar to those of other populations. In recently diagnosed patients, 5-year survival is over 92%. To the best of our knowledge, this is the first study showing that clinical features of Portuguese SSc are similar to those of other cohorts.

OBJECTIVE: To update the recommendations for the treatment of rheumatoid arthritis (RA) with biological and targeted synthetic disease-modifying antirheumatic drugs (bDMARDs and tsDMARDs), endorsed by the Portuguese Society of Rheumatology (SPR). METHODS: These treatment recommendations were formulated by Portuguese rheumatologists taking into account previous recommendations, new literature evidence and consensus opinion. At a national meeting, in a virtual format, three of the ten previous recommendations were re-addressed and discussed after a more focused literature review. A first draft of the updated recommendations was elaborated by a team of SPR rheumatologists from the SPR rheumatoid arthritis study group, GEAR. The resulting document circulated among all SPR rheumatologists for discussion and input. The level of agreement with each of all the recommendations was anonymously voted online by all SPR rheumatologists. RESULTS: These recommendations cover general aspects such as shared decision, treatment objectives, systematic assessment of disease activity and burden and its registry in Reuma.pt. Consensus was also achieved regarding specific aspects such as initiation of bDMARDs and tsDMARDs, assessment of treatment response, switching and definition of persistent remission. CONCLUSION: These recommendations may be used for guidance of treatment with bDMARDs and tsDMARDs in patients with RA. As more evidence becomes available and more therapies are licensed, these recommendations will be updated.

To compare frequency and functional activity of peripheral blood (PB) Th(c)17, Th(c)1 and Treg cells and the amount of type 2 cytokines mRNA we recruited SLE patients in active (n=15) and inactive disease (n=19) and healthy age- and gender-matched controls (n=15). The study of Th(c)17, Th(c)1 and Treg cells was done by flow cytometry and cytokine mRNA by real-time PCR. Compared to NC, SLE patients present an increased proportion of Th(c)17 cells, but with lower amounts of IL-17 per cell and also a decreased frequency of Treg, but with increased production of TGF-beta and FoxP3 mRNA. Iotan active compared to inactive SLE, there is a marked decreased in frequency of Th(c)1 cells, an increased production of type 2 cytokines mRNA and a distinct functional profile of Th(c)17 cells. Our findings suggest a functional disequilibrium of T-cell subsets in SLE which may contribute to the inflammatory process and disease pathogenesis.

OBJECTIVE: To evaluate the rate of early retirement due to rheumatoid arthritis (RA) in Portugal. METHODS: Prospective cohort study involving 11 Portuguese centers, including patients with a clinical diagnosis of RA, based on Reuma.pt registry, enrolled between 2008 and 2019. RESULTS: 3231 patients were included (81.5% female, aged 60.8 ± 13.0 years, mean disease duration 18.0 ± 10.3 years). Until the present time, 37.6% of these patients retired, 59.6% due to RA. Early retirement due to RA translated into losing 7 years of active work when compared to patients retired to other causes. Compared to professionally active patients, retired patients due to RA were diagnosed later in the disease process (p=0.003), had longer disease duration (p < 0.001), were more frequently positive for rheumatoid factor (p=0.043), had more frequently erosive disease (p < 0.001), had a blue-collar occupation (p < 0.001) and had a lower educational level (p < 0.001). Independent predictors for early retirement due to RA were: delayed diagnosis (OR: 2.23; 95% CI 1.18-4.21/year, p=0.013), erosive disease (OR: 2.21 95% CI 1.54-3.16, p < 0.001), need for biologic therapy (OR: 1.32; 95%CI 1.01-1.73, p=0.045) and lower educational level (OR: 0.83; 95%CI 0.79-0.86/year, p < 0.001). CONCLUSION: RA is, itself, the leading cause of early retirement in RA patients, accounting for the loss of an average of 7 years of active work. Delayed diagnosis, erosive disease and lower educational level are the main predictors of early retirement associated with RA in this population.

BACKGROUND AND OBJECTIVE: The number of older patients with rheumatoid arthritis is increasing, but data on drug effectiveness and safety in these patients are scarce. This study assessed the effectiveness and safety of biologic disease-modifying antirheumatic drugs in older patients with rheumatoid arthritis. METHODS: This prospective cohort study was based on data recorded in the Rheumatic Diseases Portuguese Register (Reuma.pt). Treatment persistence, European League Against Rheumatism response at 6 and 12 months, and adverse events were compared between adult (age < 65 years), old (age 65-74 years), and very old (age ≥ 75 years) patients. RESULTS: In total, 2401 patients were included, of which 379 were old and 83 were very old. Older patients had higher disease activity at baseline (Disease Activity Score 28: 5.5 in adults, 5.7 in old patients, and 6 in very old patients; p = 0.02) and more comorbidities, with patients aged 65-74 years beginning biologic disease-modifying antirheumatic drugs later in the course of rheumatoid arthritis. Treatment persistence was similar in the three patient groups (p = 0.07). The European League Against Rheumatism response rates were comparable in the three groups at 6 months (81.6% of adults, 75.2% of old patients, and 81.8% of very old patients; p = 0.19), and inferior in old patients at 12 months. The proportion of patients who experienced adverse events was also similar in the three groups (21% of adults, 22.5% of old patients, and 22.9% of very old patients; p = 0.76), but the rate of serious adverse events was higher in old patients (1.94/100 patient-years) and very old patients (4.29/100 patient-years) compared with 1.03/100 patient-years in adult patients with rheumatoid arthritis (p < 0.05). CONCLUSIONS: Adults, old patients, and very old patients with rheumatoid arthritis benefit similarly from biologic disease-modifying antirheumatic drug treatments, although older patients have more active disease at baseline and more comorbidities. However, it is necessary to consider the risk of serious adverse events in older patients when prescribing a biologic.
