RESUMEN
OBJECTIVE: To describe the frequency of polyautoimmunity and multiple autoimmune syndrome in patients with rheumatoid arthritis (RA) and patients with systemic lupus erythematosus (SLE). PATIENTS AND METHODS: This was a cross-sectional observational study of patients with RA, SLE, and controls without autoimmune rheumatic disease. Cases were those with RA according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria and SLE according to the 2019 American College of Rheumatology/European League Against Rheumatism criteria, consecutively recruited in a rheumatology clinic. Controls were subjects with no rheumatic autoimmune disease (AIDs) recruited in the same area. Patients filled out a questionnaire on polyautoimmunity. Variables of interest were polyautoimmunity (RA or SLE with other AIDs), whereas secondary variables were rheumatic, skin, endocrine, digestive, and neurological AIDs. Multiple autoimmune syndrome is defined as the presence of 3 or more AIDs and a family history of AIDs. Statistical analyses performed were descriptive, bivariate, and multivariate (dependent variable: polyautoimmunity). RESULTS: The study population comprised 109 patients with RA, 105 patients with SLE, and 88 controls. Polyautoimmunity was recorded in 15 patients with RA (13.8%), 43 with SLE (41%), and 2 controls (2.2%). The most frequent AID in RA was Sjögren syndrome (53.3%), followed by Hashimoto thyroiditis and psoriasis; the most frequent AIDs in SLE were Sjögren syndrome (55.8%) and antiphospholipid syndrome (30.2%), followed by Hashimoto thyroiditis. Obesity was associated with polyautoimmunity in RA (odds ratio [OR], 3.362; p = 0.034). In SLE, joint damage (OR, 2.282; p = 0.038) and anti-RNP antibodies (OR, 5.095; p = 0.028) were risk factors for polyautoimmunity, and hydroxychloroquine was a protective factor (OR, 0.190; p = 0.004). CONCLUSIONS: Polyautoimmunity is frequent in RA and even more frequent in SLE. It was associated with obesity in RA and with joint damage and anti-RNP in SLE. Hydroxychloroquine was a protector.

OBJECTIVE: To describe the incidence and fatality of coronavirus disease 2019 (COVID-19) and identify risk factors to fatality in patients with inflammatory articular diseases (IAD). METHODS: This is a cross-sectional observational study of IAD patients and COVID-19 with controls matched for age, sex, and RT-PCR. A control group was used to compare the cumulative incidence (CI) and case fatality rate (CFR). The main outcomes of the study were CI and CFR. Other variables included comorbidities, treatments, and characteristics of the COVID-19. Multiple logistic regression analysis was performed to investigate risk factors for fatality in patients with IAD. RESULTS: Of the 1537 patients who fulfilled the inclusion criteria, 23/1537 (1.49%) had IAD 13 (0.8%) had rheumatoid arthritis (RA), 5 psoriatic arthritis (PsA) (0.3%) and 5 axial spondyloarthritis (0.3%). There were no significant differences in CI of COVID-19 and CFR in patients with IAD compared with COVID-19 patients without IAD. In RT-PCR positive patients, the CI of COVID-19 in PsA and AS was higher. Of the 23 IAD patients, 2 RA patients (8.6%) died. The patients did no show characteristics of the COVID-19 disease different from the population. In multivariate analysis, the factor associated with fatality in patients with IAD was older age (OR [95% CI], 1.1 [1.0-1.2]). CONCLUSION: COVID-19 CI, fatality rate and other features do not seem to be increased in IAD patients. Older age was associated with fatality in patients with IAD.

The aims of this study were to evaluate adherence of rheumatoid arthritis (RA) patients to biological disease-modifying antirheumatic drugs (bDMARDs), identify potential risk factors, and analyze the discriminative ability of the Morisky-Green test (MGT) to detect bDMARD nonadherence. One hundred and seventy-eight adult RA patients treated with bDMARDs were included. Adherence was measured using the medication possession ratio (MPR) of the previous 6 months. An MPR >80% was considered good adherence. Patient demographics, clinical characteristics, and MGT scores were assessed through a standardized clinical interview at the cross-sectional date. One-hundred and twelve patients (63%) were taking subcutaneous bDMARDs, while 66 (37%) were taking intravenous drugs. One-hundred fifty-eight (88.8%) showed good adherence to bDMARDs, while 79 (61.2%) also correctly took concomitant conventional synthetic DMARDs (csDMARDs). In logistic regression models, nonadherence to bDMARDs was associated with higher disease activity [odds ratio (OR) 1.45; 95% CI, 1.03-2.03; p = 0.032] and subcutaneous route (OR 3.70; 95% CI 1.02-13.48; p = 0.040). MGT accurately identified an MPR >80% of bDMARDs in 76.9% of the patients. A sensitivity of 78%, specificity of 70%, positive predictive value of 95.3%, negative predictive value of 28.5%, positive likelihood ratio (LR) of 2.6, and negative LR of 0.3% were obtained. Adherence may be good for bDMARDs but is low for csDMARDs. Low adherence for bDMARDs is associated with poorer disease control during the past 6 months and use of subcutaneous route. These findings should alert doctors to consider possible low adherence before declaring treatment failure.

We evaluated the efficacy of a triage approach based on a combination of osteoporosis risk-assessment tools plus peripheral densitometry to identify low bone density accurately enough to be useful for clinical decision making in postmenopausal women. We conducted a cross-sectional diagnostic study in postmenopausal Caucasian women from primary and tertiary care. All women underwent dual-energy X-ray absorptiometric (DXA) measurement at the hip and lumbar spine and were categorized as osteoporotic or not. Additionally, patients had a nondominant heel densitometry performed with a PIXI densitometer. Four osteoporosis risk scores were tested: SCORE, ORAI, OST, and OSIRIS. All measurements were cross-blinded. We estimated the area under the curve (AUC) to predict the DXA results of 16 combinations of PIXI plus risk scores. A formula including the best combination was derived from a regression model and its predictability estimated. We included 505 women, in whom the prevalence of osteoporosis was 20 %, similar in both settings. The best algorithm was a combination of PIXI + OST + SCORE with an AUC of 0.826 (95 % CI 0.782-0.869). The proposed formula is Risk = (-12) × [PIXI + (-5)] × [OST + (-2)] × SCORE and showed little bias in the estimation (0.0016). If the formula had been implemented and the intermediate risk cutoff set at -5 to 20, the system would have saved

OBJECTIVE: To evaluate sleep disorders and associated factors in patients with rheumatoid-arthritis-associated interstitial lung disease (RA-ILD). METHODS: We performed an observational study of 35 patients with RA-ILD (cases) and 35 age- and sex-matched RA patients without ILD (controls). We evaluated sleep disorders (Oviedo Sleep Questionnaire), positive psychological factors (resilience using the Wagnild and Young Resilience Scale, emotional intelligence using the 24-item Trait Meta-Mood Scale), anxiety and depression (Hospital Anxiety and Depression Scale), quality of life (36-item short-form survey), and fatigue (Functional Assessment of Chronic Illness Therapy Questionnaire). Other variables studied included the Charlson Comorbidity Index (CCI) and RA activity according to the DAS28-ESR. RESULTS: Compared to the controls, the cases were characterized by poorer sleep quality with a higher prevalence of insomnia (42% vs. 20%; p = 0.039), greater severity of insomnia (p = 0.001), and lower sleep satisfaction (p = 0.033). They also had poorer resilience and emotional recovery and more severe anxiety and depression. A diagnosis of ILD was the only factor independently associated with the three dimensions of sleep quality. The predictors of poorer sleep satisfaction in patients with RA-ILD were age (ß = -0.379), DAS28-ESR (ß = -0.331), and usual interstitial pneumonia pattern (ß = -0.438). The predictors of insomnia were DAS28-ESR (ß = 0.294), resilience (ß = -0.352), and CCI (ß = 0.377). CONCLUSIONS: RA-ILD is associated with significant sleep disorders. RA-ILD seems to be an independent risk factor for sleep alterations, with a greater impact on insomnia. Age, disease activity, and comorbidity also play a role in sleep disorders in patients with RA-ILD.
RESUMEN
OBJECTIVES: To analyze the efficacy and safety of rituximab (RTX) in connective tissue disease associated with interstitial lung disease (CTD-ILD). METHODS: We performed a multicenter, prospective, observational study of patients with CTD-ILD receiving rituximab between 2015 and 2020. The patients were assessed using high-resolution computed tomography and pulmonary function tests at baseline, at 12 months, and at the end of follow-up. The main outcome measure at the end of follow-up was forced vital capacity (FVC) > 10% or diffusing capacity of the lungs for carbon monoxide (DLCO) > 15% and radiological progression or death. We recorded clinical characteristics, time to initiation of RTX, concomitant treatment, infections, and hospitalization. A Cox regression analysis was performed to identify factors associated with worsening ILD. RESULTS: We included 37 patients with CTD-ILD treated with RTX for a median (IQR) of 38.2 (17.7-69.0) months. At the end of the follow-up, disease had improved or stabilized in 23 patients (62.1%) and worsened in seven (18.9%); seven patients (18.9%) died. No significant decline was observed in median FVC (72.2 vs. 70.8; p = 0.530) or DLCO (55.9 vs. 52.2; p = 0.100). The multivariate analysis showed the independent predictors for worsening of CTD-ILD to be baseline DLCO (OR (95% CI), 0.904 (0.8-0.9); p = 0.015), time to initiation of RTX (1.01 (1.001-1.02); p = 0.029), and mycophenolate (0.202 (0.04-0.8); p = 0.034). Only 28 of the 37 patients (75.6%) were still undergoing treatment with RTX: two patients (5.4%) stopped treatment due to adverse events and seven patients (18.9%) died owing to progression of ILD and superinfection. CONCLUSION: Lung function improved or stabilized in more than half of patients with CTD-ILD treated with RTX. Early treatment and combination with mycophenolate could reduce the risk of progression of ILD.
RESUMEN
Objectives: To describe the frequency of COVID-19 and the effect of vaccination in patients with interstitial lung disease and systemic autoimmune disease (ILD-SAD) and to identify factors associated with infection and severity of COVID-19. Methods: We performed a cross-sectional multicenter study of patients with ILD-SAD followed between June and October 2021. The main variable was COVID-19 infection confirmed by a positive polymerase chain reaction (PCR) result for SARS-CoV-2. The secondary variables included severity of COVID-19, if the patient had to be admitted to hospital or died of the disease, and vaccination status. Other variables included clinical and treatment characteristics, pulmonary function and high-resolution computed tomography. Two logistic regression was performed to explore factors associated with "COVID-19" and "severe COVID-19". Results: We included 176 patients with ILD-SAD: 105 (59.7%) had rheumatoid arthritis, 49 (27.8%) systemic sclerosis, and 22 (12.54%) inflammatory myopathies. We recorded 22/179 (12.5%) SARS-CoV-2 infections, 7/22 (31.8%) of them were severe and 3/22 (13.22%) died. As to the vaccination, 163/176 (92.6%) patients received the complete doses. The factors associated with SARS-CoV-2 infection were FVC (OR (95% CI), 0.971 (0.946−0.989); p = 0.040), vaccination (OR (95% CI), 0.169 (0.030−0.570); p = 0.004), and rituximab (OR (95% CI), 3.490 (1.129−6.100); p = 0.029). The factors associated with severe COVID-19 were the protective effect of the vaccine (OR (95% CI), 0.024 (0.004−0.170); p < 0.001) and diabetes mellitus (OR (95% CI), 4.923 (1.508−19.097); p = 0.018). Conclusions: Around 13% of patients with ILD-SAD had SARS-CoV-2 infection, which was severe in approximately one-third. Most patients with severe infection were not fully vaccinated.
RESUMEN
OBJECTIVE: Sarcopenia is a major cause of morbidity in rheumatoid arthritis patients. Our purpose was to determine whether polyautoimmunity is associated with sarcopenia and alterations in whole body composition in patients with rheumatoid arthritis (RA). METHODS: We performed a cross-sectional observational study of a series of cases of RA. All patients were recruited consecutively from a rheumatology clinic. Body composition by dual-energy x-ray absorptiometry (DEXA) was assessed. The variables of interest were polyautoimmunity (RA associated with other autoimmune diseases), sarcopenia, fat mass, and body mass index (BMI). Other variables included were clinical-analytical and inflammatory cytokines and adipokines. The relationship between sarcopenic obesity and the presence of polyautoimmunity was studied using multivariate analysis. RESULTS: Of the 94 patients with RA included in the study, 15 (16%) had polyautoimmunity. A total of 23 patients with RA (24.5%) had sarcopenia, which was more prevalent in patients with polyautoimmunity than in patients without polyautoimmunity (46.7% vs 20.3%; p = .029). Sarcopenia was not associated with body fat content (p = .870) or with BMI (p = .998). The multivariate analysis showed the factors associated with polyautoimmunity in RA to be sarcopenia (odds ratio [95% CI], 4.80 [1.49-13.95]), BMI (1.18 [1.04-1.35]), and resistin (1.249 [1.01-1.53]). CONCLUSION: Sarcopenia and obesity were more prevalent in patients with RA and polyautoimmunity. Resistin values were also higher in this group than in patients with RA without polyautoimmunity.

A human motion capture system using an RGB-D camera could be a good option to understand the trunk limitations in spondyloarthritis. The aim of this study is to validate a human motion capture system using an RGB-D camera to analyse trunk movement limitations in spondyloarthritis patients. Cross-sectional study was performed where spondyloarthritis patients were diagnosed with a rheumatologist. The RGB-D camera analysed the kinematics of each participant during seven functional tasks based on rheumatologic assessment. The OpenNI2 library collected the depth data, the NiTE2 middleware detected a virtual skeleton and the MRPT library recorded the trunk positions. The gold standard was registered using an inertial measurement unit. The outcome variables were angular displacement, angular velocity and lineal acceleration of the trunk. Criterion validity and the reliability were calculated. Seventeen subjects (54.35 (11.75) years) were measured. The Bending task obtained moderate results in validity (r = 0.55-0.62) and successful results in reliability (ICC = 0.80-0.88) and validity and reliability of angular kinematic results in Chair task were moderate and (r = 0.60-0.74, ICC = 0.61-0.72). The kinematic results in Timed Up and Go test were less consistent. The RGB-D camera was documented to be a reliable tool to assess the movement limitations in spondyloarthritis depending on the functional tasks: Bending task. Chair task needs further research and the TUG analysis was not validated. Comparation of both systems, required software for camera analysis, outcomes and final results of validity and reliability of each test.

OBJECTIVE: To assess the effectiveness, safety and cost of Etanercept biosimilar in patients with rheumatoid arthritis (RA), spondyloarthritis (SpA) and psoriatic arthritis (PsA) compared to the standard drug in real clinical practice. PATIENTS AND METHODS: Retrospective observational study. Case series of 138 patients with RA, SpA or PsA treated with at least one dose of Benepali® (nâ¯=â¯79) or Enbrel® (nâ¯=â¯59). Drug retention time was the primary efficacy endpoint compared to the biosimilar and the original. The proportion of patients achieving low disease activity or remission after 52â¯weeks was used as the secondary outcome. Safety was assessed by means of the adverse effects incidence rate. A cost minimization analysis was performed. RESULTS: No differences were observed regarding treatment retention time between drugs (median [95% confidence interval, 95%â¯CI] at 12.0â¯months [10.2-12.0] for the biosimilar and 12.0â¯months [12.0-12.0] for the original). Similar improvements, in terms of inflammatory activity and physical function, were obtained after 52â¯weeks except for patients with SpA and PsA who, in general, experienced improvements of BASDAI and ASDAS with the original compared with the biosimilar. No significant differences were observed in the total number of adverse effects (.43 events/patient-years versus the biosimilar and .53 versus the original). Using the biosimilar in place of the original drug resulted in a net savings of 118,383.55⯠(1,747.20â¯/patient-years) for the hospital. CONCLUSION: The biosimilar Benepali is as effective and safe as the original and much more cost-effective.

OBJECTIVES: To analyze the diagnostic utility of lung ultrasound (US) to detect interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients comparing with high-resolution computed tomography (HRCT) PATIENTS AND METHODS: We performed a cross-sectional, observational study in patients with RA-ILD (cases) controlled with a group of RA patients without ILD (controls) paired by sex, age, and time of disease evolution. Patients were assessed using HRCT, PFT, and US. The main variables were B-line number, evaluation of the lung-US score already described, pleural irregularities, and A pattern US lost. ROC curve analysis was performed to establish the cut-off point of the US B-lines number for detecting the presence of significant RA-ILD in relation to HRCT, and logistic regression analysis was performed to identify the intercostal spaces. RESULTS: Seventy-one patients were included, 35 (49.2%) with ILD-RA and 36 (50.8%) RA controls. Regarding US score, we found that the detection of 5.5 lines in a reduced score of 8 intercostal spaces had a sensitivity = 62.2%, specificity = 91.3%, PPV = 88.4%, and NPV = 69.5%. In multivariate analysis, the intercostal spaces which showed independent association with ILD were 3rd right anterior axillary space (OR [IC 95%] 19.0 [1.3-27.5]), 8th right posterior axillary space (OR [IC 95%] 0.04 [0.0-0.6]), 8th right subscapular space (OR [IC 95%] 16.5 [1.8-45.5]), 9th right paravertebral space (OR [IC 95%] 7.11 [1.0-37.1]), and 2nd left clavicular middle space (OR [IC 95%] 21.9 [1.26-37.8]). CONCLUSIONS: Lung ultrasound could be a useful tool for ILD diagnosis associated with rheumatoid arthritis. A 8-space reduced score showed a similar total predictive capacity than 72-space score. Key Points ⢠Lung ultrasound could be a useful tool for ILD diagnosis associated with rheumatoid arthritis. ⢠The 72-space evaluation is highly sensitive, whereas a simplified score enables a more specific and faster diagnosis. ⢠The number of B lines is correlated with DLCO, ACPA, inflammatory activity, and physical function.

OBJECTIVES: To analyze the effect of disease-modifying antirheumatic drugs (DMARDs) on the outcome of interstitial lung disease secondary to rheumatoid arthritis (RA-ILD). PATIENTS AND METHODS: We performed a multicenter, prospective, observational study of patients with RA-ILD receiving DMARDs between 2015 and 2017. The patients were assessed using high-resolution computed tomography and pulmonary function tests at baseline and at 24 months. The radiological assessment was centralized. The main outcome measure at 24 months was changed in lung function (improvement, stabilization, worsening, or death). We recorded the 28-joint Disease Activity Score 28 (DAS28) and adverse events. A logistic regression analysis was performed to identify factors associated with worsening of ILD. RESULTS: After 24 months, lung disease was stabilized in 40 patients (57.1%), improved in 8 (11.4%), and worse in 21 (30.0%). One patient (1.4%) died. The factors associated with worsening of ILD in the multivariate analysis were treatment with abatacept, tocilizumab, or rituximab (OR, 0.102 [95%CI, 0.015-0.686]), DAS28 (OR, 1.969 [95%CI, 1.005-3.857]), and smoking (OR, 6.937 [95%CI, 1.378-4.900]). During follow-up, 30 patients (42.9%) experienced an adverse event, which was severe in 12 cases (17.1%). CONCLUSIONS: Lung function is stable and inflammatory activity well controlled in most patients with RA-ILD receiving treatment with DMARDs. Non-anti-TNF DMARDs reduce the risk of worsening of lung disease in 90% of patients. The inflammatory activity of RA and smoking, on the other hand, are associated with worsening. Key Points ⢠We have performed prospectively evaluated lung and joint function in patients with RA-ILD receiving treatment with various DMARDs. ⢠In our study, the lung function is stable and inflammatory activity well controlled in most patients with RA-ILD receiving treatment with DMARDs. ⢠Neither csDMARDs nor anti-TNF agents were associated with a significant risk of worsening of lung disease, whereas non-anti-TNF bDMARDs could reduce the risk of worsening of lung disease. ⢠Smoking and poor control of joint involvement were the main factors associated with worsening of lung disease.

OBJECTIVES: To describe the characteristics and progression of interstitial lung disease in patients with associated systemic autoimmune disease (ILD-SAI) and to identify factors associated with progression and mortality. PATIENTS AND METHODS: We performed a multicenter, retrospective, observational study of patients with ILD-SAI followed between 2015 and 2020. We collected clinical data and performed pulmonary function testing and high-resolution computed tomography at diagnosis and at the final visit. The main outcome measure at the end of follow-up was forced vital capacity (FVC) >10% or diffusing capacity of the lungs for carbon monoxide >15% and radiological progression or death. Cox regression analysis was performed to identify factors associated with worsening of ILD. RESULTS: We included 204 patients with ILD-SAI: 123 (60.3%) had rheumatoid arthritis (RA), 58 had (28.4%) systemic sclerosis, and 23 (11.3%) had inflammatory myopathy. After a median (IQR) period of 56 (29.8-93.3) months, lung disease had stabilized in 98 patients (48%), improved in 33 (16.1%), and worsened in 44 (21.5%). A total of 29 patients (14.2%) died. Progression and hospitalization were more frequent in patients with RA (p = 0.010). The multivariate analysis showed the independent predictors for worsening of ILD-SAI to be RA (HR, 1.9 [95% CI, 1.3-2.7]), usual interstitial pneumonia pattern (HR, 1.7 [95% CI, 1.0-2.9]), FVC (%) (HR, 2.3 [95% CI, 1.4-3.9]), and smoking (HR, 2.7 [95%CI, 1.6-4.7]). CONCLUSION: Disease stabilizes or improves after a median of 5 years in more than half of patients with ILD-SAI, although more than one-third die. Data on subgroups and risk factors could help us to predict poorer outcomes.
RESUMEN
OBJECTIVES: To describe a prospective cohort of patients with rheumatoid arthritis associated with interstitial lung disease (RA-ILD) and identify risk factors associated with disease progression and mortality in this cohort. PATIENTS AND METHODS: We performed a multicenter, prospective, observational study of patients with RA-ILD receiving disease-modifying antirheumatic drugs (DMARDs) between 2015 and 2020. The patients were assessed using high-resolution computed tomography and pulmonary function tests at baseline and at 60 months. The main endpoint was "Progression to ILD at the end of follow-up" in terms of the following outcomes: (1) improvement (i.e., improvement in forced vital capacity (FVC) ≥10% or diffusing capacity of the lungs for carbon monoxide (DLCO) ≥15% and absence of radiological progression); (2) nonprogression (stabilization or improvement in FVC ≤10% or diffusing capacity of the lungs for carbon monoxide (DLCO) <15% and absence of radiological progression); (3) progression (worsening of FVC >10% or DLCO >15% and radiological progression); or (4) death. We recorded demographic and clinical characteristics, lung function, and the incidence of adverse events. A Cox regression analysis was performed to identify factors associated with the worsening of ILD. RESULTS: After 60 months, lung disease had stabilized in 66 patients (56.9%), improved in 9 (7.8%), and worsened in 23 (19.8%). Eighteen patients (15.5%) died, with a mean survival of 71.8 (1.9) months after diagnosis of ILD. The Cox multivariate analysis revealed the independent predictors of worsening of RA-ILD to be usual interstitial pneumonia (hazard ratio (HR), 2.6 (95%CI, 1.0-6.7)), FVC <80% (HR, 3.8 (95%CI, 1.5-6.7)), anticitrullinated protein antibody titers (HR, 2.8 (95%CI, 1.1-6.8)), smoking (HR, 2.5 (95%CI, 1.1-6.2)), and treatment with abatacept, tocilizumab, or rituximab (HR, 0.4 (95%CI, 0.2-0.8)). During follow-up, 79 patients (68%) experienced an adverse event, mostly infection (61%). Infection was fatal in 10/18 patients (55.5%) during follow-up. CONCLUSIONS: Lung function is stable in most patients with RA-ILD receiving treatment with disease-modifying anti-rheumatic drugs (DMARDs), although one-third worsened or died. Identifying factors associated with worsening in RA-ILD is important for clinical management.
RESUMEN
OBJECTIVES: To study the differences between rheumatoid arthritis (RA)-interstitial lung disease (ILD) patients and RA patients without ILD in severity markers and disease activity and to identify factors associated with the presence of ILD in RA patients. PATIENTS AND METHODS: Patients: RA-ILD patients selected from a multicentre cohort in Andalusia, Spain. CONTROLS: RA-patients without ILD paired by sex, age and disease duration. PROTOCOL: RA patients are reviewed every 3-6months in rheumatology consultation. All patients are reviewed according to a predetermined protocol with systematic data collection. OUTCOMES: description of ILD type, differences in severity markers and disease activity in both groups. Other variables: ILD type by imaging technique (HRCT): nonspecific interstitial pneumonia (NSIP)/usual interstitial pneumonia (UIP). Lung function by PTF. Activity and severity markers of arthritis by DAS28-ESR, HAQ, RF, ACPA and erosions. Treatment with DMARD. STATISTICAL ANALYSIS: descriptive and paired T-test or Chi-square test followed by binary logistic regression (DV: ILD in patients with RA). RESULTS: Eighty-two patients were included, 41 RA-ILD and 41 RA controls. RF and ACPA positivity, serositis and osteoporosis were more frequent in RA-ILD patients. No significant differences in DAS28 were observed (P=.145) between RA-ILD and RA control patients. RA-ILD patients presented worse HAQ scores (P=.006). All patients were treated with disease modifying antirheumatic drugs (DMARDs). The risk of developing ILD in RA patients is tripled by a history of smoking or the presence of erosive arthritis (R2=.36). CONCLUSIONS: The results of our study support the higher frequency of UIP and NSIP in RA patients. DLCO is the most sensitive parameter to detect ILD in RA patients. Our study showed that ILD in RA patients was associated with RA severity (presence of erosions and ACPA) and with a history of smoking.
RESUMEN
OBJECTIVE: To evaluate the effectiveness and safety of tocilizumab (TCZ) in patients with rheumatoid arthritis (RA) in clinical practice, establishing the optimized regimen and switching from intravenous (IV) to subcutaneous (SC) therapy. MATERIAL AND METHODS: Retrospective observational study. We included 53 RA patients treated with TCZ. The main outcome was TCZ effectiveness at week 24. Secondary outcome variables included effectiveness at week 52, therapeutic maintenance, physical function and safety. The effectiveness of optimization and the switch from IV to SC was evaluated at 3 and 6 months. The efficacy was measured with the Disease Activity Score. Paired t-tests or Wilcoxon were used to evaluate effectiveness and survival time using Kaplan-Meier. RESULTS: The proportion of patients who achieved remission or low disease activity at weeks 24 and 52 was 75.5% and 87.3%, respectively. The mean retention time (95% confidence interval [95% CI] was 81.7 months [76.6-86.7]). Twenty-one of 53 patients (39.6%) optimized the TCZ dose and 35 patients switched from IV TCZ to SC, with no changes in effectiveness. The adverse event rate was 13.6 events/100 patient-years. CONCLUSIONS: Tocilizumab appears to be effective and safe in RA in clinical practice. The optimized regimen appears to be effective in most patients in remission, even when they change from IV to SC.

OBJECTIVE: Evaluate the effectiveness, cost and safety of rituximab in patients with rheumatoid arthritis (RA) depending on the dose used. MATERIAL AND METHODS: Retrospective observational study conducted on 52 patients with RA treated with at least one dose of rituximab for 135.3 patient-years were included. Three treatment groups were obtained: (G1) First course and following two 1g infusions separated by 15 days; (G2) First course 2 infusions of 1g followed by 2 infusions of 500mg; (G3) First course and followed by 2 infusions of 500mg separated by 15 days. Re-treatments were administered on-demand according to the clinical activity. The retention time (Log-Rank), retreats and adverse events rates (incidence rate ratio) and treatment costs per patient-month of rituximab were analysed by groups. RESULTS: Group 2 showed a better cost-effectiveness ratio than group 1, as it was associated with a longer retention of rituximab (mean [95% CI] 65.7 [60.8 to 70.7] months vs 33.5 [22.7 to 44.3]; P<.001) and a lower rate of severe adverse events with only a slight increase in the rate of retreatment (courses/patient-year [95% CI] 1.66 [1.39 to 1.93] vs. 1.01 [0.69 to 1.34]; P=.005), and in the costs (median/patient-month, 484.89 vs. 473.45). Although group 3 was 41.20/patient-month cheaper than group 2, it was associated with a higher rate of re-treatments and shorter retention of rituximab (P<.001). CONCLUSIONS: The use of full-dose rituximab at onset, followed by reduced doses in successive courses administered on-demand retreatment may be the most cost-effective option.

Objetivo: Evaluar la efectividad, la seguridad y los costes de etanercept biosimilar (BS) en pacientes con artritis reumatoide (AR), espondiloartritis (EspA) y artritis psoriásica (APs) y en comparación con su original, en condiciones de práctica clínica habitual. Pacientes y métodos: Estudio observacional retrospectivo. Se incluyeron 138 pacientes con AR, EspA o APs tratados con al menos una dosis de Benepali® (n=79) o Enbrel® (n=59). Como desenlace principal de efectividad del BS o de su original se usó el tiempo de retención del fármaco. Como desenlace secundario de efectividad se midió la proporción de pacientes que alcanzaban baja actividad o remisión a las 52semanas. La seguridad fue evaluada mediante tasas de incidencia de efectos adversos. Se hizo un análisis de minimización de costes. Resultados: No se observaron diferencias en cuanto a retención del tratamiento (mediana [intervalo de confianza del 95%, IC95%] de 12,0meses [10,2-12,0] para BS y 12,0 meses [12,0-12,0] para el original). Se obtuvieron mejorías similares después de 52semanas en actividad inflamatoria y función física, excepto en los pacientes con EspA y APs, que en general obtuvieron mejores valores de BASDAI y ASDAS con el BS. No se registraron diferencias en el número total de efectos adversos (0,43 eventos/pacientes-año con BS frente a 0,53 con original). El uso del BS, en lugar de su original, supuso un ahorro neto para el centro de 118.383,55 (1.747,2/pacientes-año). Conclusiones: El uso del BS parece tan eficaz y seguro como su original y mucho más coste-efectivo.(AU)
Objective: To assess the effectiveness, safety and cost of Etanercept biosimilar in patients with rheumatoid arthritis (RA), spondyloarthritis (SpA) and psoriatic arthritis (PsA) compared to the standard drug in real clinical practice. Patients and methods: Retrospective observational study. Case series of 138 patients with RA, SpA or PsA treated with at least one dose of Benepali® (n=79) or Enbrel® (n=59). Drug retention time was the primary efficacy endpoint compared to the biosimilar and the original. The proportion of patients achieving low disease activity or remission after 52weeks was used as the secondary outcome. Safety was assessed by means of the adverse effects incidence rate. A cost minimization analysis was performed. Results: No differences were observed regarding treatment retention time between drugs (median [95% confidence interval, 95%CI] at 12.0months [10.2-12.0] for the biosimilar and 12.0months [12.0-12.0] for the original). Similar improvements, in terms of inflammatory activity and physical function, were obtained after 52weeks except for patients with SpA and PsA who, in general, experienced improvements of BASDAI and ASDAS with the original compared with the biosimilar. No significant differences were observed in the total number of adverse effects (.43 events/patient-years versus the biosimilar and .53 versus the original). Using the biosimilar in place of the original drug resulted in a net savings of 118,383.55 (1,747.20/patient-years) for the hospital. Conclusion: The biosimilar Benepali is as effective and safe as the original and much more cost-effective.(AU)

Objetivos: Estudiar las diferencias en pacientes con artritis reumatoide (AR) y enfermedad pulmonar intersticial (EPID) y pacientes con AR sin EPID, e identificar factores asociados con la EPID en pacientes con AR. Pacientes y métodos: Estudio observacional de casos y controles. Pacientes: se seleccionaron pacientes de una cohorte con AR y EPID de diferentes centros de Andalucía. Controles: pacientes con AR sin EPID pareados por edad, género y tiempo de evolución. Protocolo: los pacientes con AR se revisan cada 3-6meses en consulta. Todos los pacientes son revisados de acuerdo con un protocolo predeterminado con recogida de datos sistemática. Desenlaces: descripción del tipo radiológico de EPID, diferencias en los marcadores de gravedad en casos y controles y en la actividad de la enfermedad. Otras variables: descripción del tipo de EPID por TACAR: neumonía intersticial usual (NIU), neumonía intersticial no específica (NINE) y de la función pulmonar por PFR; marcadores de actividad y gravedad de artritis: DAS28, HAQ, FR, ACPA, erosiones. Tratamiento con FAME. Análisis: descriptivo, χ2 o t de Student, seguida de regresión logística binaria (Vd:EPID en pacientes con AR). Resultados: Se incluyeron 82 pacientes: 41 con AR y EPID y 41 controles AR sin EPID. Los pacientes con EPID presentaron un mayor porcentaje de pacientes con FR y ACPA positivos y una mayor frecuencia de serositis y osteoporosis. No hubo diferencias significativas en DAS28 en casos y controles(p=0,145), pero los pacientes de AR con EPID presentaron peor HAQ (p=0,006). Todos los pacientes estaban en tratamiento con FAME. El análisis multivariante mostró que los pacientes con AR exfumadores y con artritis erosiva triplicaron el riesgo de presentar EPID (R2=0,36). Conclusiones: Los resultados de nuestro estudio apoyan la mayor frecuencia de NIU y NINE en pacientes con AR, así como la alteración de DLCO como el parámetro más importante.(AU)
Objectives: To study the differences between rheumatoid arthritis (RA)-interstitial lung disease (ILD) patients and RA patients without ILD in severity markers and disease activity and to identify factors associated with the presence of ILD in RA patients. Patients and methods: Patients: RA-ILD patients selected from a multicentre cohort in Andalusia, Spain. Controls: RA-patients without ILD paired by sex, age and disease duration. Protocol: RA patients are reviewed every 3-6months in rheumatology consultation. All patients are reviewed according to a predetermined protocol with systematic data collection. Outcomes: description of ILD type, differences in severity markers and disease activity in both groups. Other variables: ILD type by imaging technique (HRCT): nonspecific interstitial pneumonia (NSIP)/usual interstitial pneumonia (UIP). Lung function by PTF. Activity and severity markers of arthritis by DAS28-ESR, HAQ, RF, ACPA and erosions. Treatment with DMARD. Statistical analysis: descriptive and paired T-test or Chi-square test followed by binary logistic regression (DV: ILD in patients with RA). Results: Eighty-two patients were included, 41 RA-ILD and 41 RA controls. RF and ACPA positivity, serositis and osteoporosis were more frequent in RA-ILD patients. No significant differences in DAS28 were observed (P=.145) between RA-ILD and RA control patients. RA-ILD patients presented worse HAQ scores (P=.006). All patients were treated with disease modifying antirheumatic drugs (DMARDs). The risk of developing ILD in RA patients is tripled by a history of smoking or the presence of erosive arthritis (R2=.36). Conclusions: The results of our study support the higher frequency of UIP and NSIP in RA patients. DLCO is the most sensitive parameter to detect ILD in RA patients. Our study showed that ILD in RA patients was associated with RA severity (presence of erosions and ACPA) and with a history of smoking.(AU)
