The effect of antimalarials on the safety and persistence of treatment with biologic agents or Janus kinase inhibitors in rheumatoid arthritis.

OBJECTIVES: To test the association of use of antimalarials with the overall safety of treatment in RA patients receiving one or multiple courses of biologic (b)DMARDs or a Janus kinase inhibitor (JAKi). METHODS: BiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their first bDMARD or JAKi. The present analysis includes RA patients recruited from January 2009 to October 2019, followed up over one or multiple (up to six) courses of treatment (latest date, 19 November 2019). The primary outcome was the incidence of serious adverse events (SAEs). Total and system-specific adverse events (AEs) and treatment interruption served as secondary outcomes. Negative binomial regression with generalized estimating equations (to estimate multivariate incidence rate ratios, mIRR) and frailty Cox proportional hazards models were used for statistical analyses. RESULTS: The number of patients enrolled was 1316 (2335 treatment courses, 6711 patient-years [PY]; 1254.5 PY on antimalarials). The overall incidence of SAEs was 9.2/100 PY. Antimalarials were associated with reduced risk of SAEs (mIRR: 0.49; 95% CI: 0.36, 0.68; P < 0.001), total AEs (0.68; 95% CI: 0.56, 0.81; P < 0.001), serious infections (0.53; 95% CI: 0.34, 0.84; P = 0.007) and total hepatic AEs (0.21; 95% CI: 0.05, 0.85; P = 0.028). Antimalarials were also related to better survival of treatment course (P = 0.003). There was no significant increase in the risk of cardiovascular AEs. CONCLUSION: Among RA patients on treatment with bDMARDs or JAKi, concomitant use of antimalarials was associated with reduced the incidence of serious and total AEs and with longer treatment course survival.

Cardiovascular Events, Malignancies, and Efficacy Outcomes in Latin American Patients With Rheumatoid Arthritis Receiving Tofacitinib or Tumor Necrosis Factor Inhibitors: A Post Hoc Analysis of the ORAL Surveillance Study.

BACKGROUND/OBJECTIVE: To assess safety/efficacy of tofacitinib and tumor necrosis factor inhibitors (TNFi) in patients from Latin America (LATAM) in ORAL Surveillance. METHODS: In ORAL Surveillance, 4362 patients with rheumatoid arthritis aged ≥50 years with ≥1 additional cardiovascular risk factor received tofacitinib 5 or 10 mg twice daily or TNFi. This post hoc analysis stratified patients by geographical location (LATAM, n = 1202; non-LATAM, n = 3160). Incidence rates (IRs; patients with first event/100 patient-years) and hazard ratios for adverse events of special interest were reported. Efficacy outcomes included Clinical Disease Activity Index and American College of Rheumatology 20/50/70 responses. RESULTS: Risk factors associated with cardiovascular disease and malignancies were less prevalent in the LATAM cohort compared with the non-LATAM cohort. IRs for patients receiving tofacitinib (combined doses) versus TNFi were 0.54 versus 0.28 (LATAM) and 1.14 versus 0.92 (non-LATAM) for major adverse cardiovascular events; 0.58 versus 0.27 (LATAM) and 1.33 versus 0.95 (non-LATAM) for malignancies excluding nonmelanoma skin cancer; and 0.69 versus 0.35 (LATAM) and 0.63 versus 0.33 (non-LATAM) for all-cause death. IRs for nonmelanoma skin cancer and venous thromboembolism were also numerically higher with tofacitinib versus TNFi and in the non-LATAM cohort versus LATAM. Efficacy was similar across treatment groups within each cohort. CONCLUSIONS: Adverse events of special interest were generally less frequent in LATAM versus non-LATAM patients, reflecting differences in baseline characteristics, and higher with tofacitinib versus TNFi in both cohorts, consistent with the overall findings of ORAL Surveillance. Our findings emphasize the importance of assessing individual risk factors to guide benefit/risk assessment and treatment decisions. CLINICAL TRIAL REGISTRATION NUMBER: NCT02092467.

Factors Associated With Mortality in Patients With Immune-Mediated Rheumatic Diseases and COVID-19 From Latin America: Data From Argentina, Mexico, and Brazil.

OBJECTIVE: To describe characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with rheumatic immune-mediated inflammatory diseases (IMIDs) from Argentina, Mexico and Brazil, and to assess factors associated with mortality in this population. METHODS: Data from 3 national registries, SAR-COVID (Argentina), CMR-COVID (Mexico), and ReumaCoV-Brasil (Brazil), were combined. Adult patients with IMIDs and SARS-CoV-2 infection were recruited. Sociodemographic data, comorbidities, IMID clinical characteristics and treatment, and SARS-CoV-2 infection presentation and outcomes were recorded. RESULTS: A total of 4827 individuals were included: 2542 (52.7%) from SAR-COVID, 1167 (24.2%) from CMR-COVID, and 1118 (23.1%) from ReumaCoV-Brasil. Overall, 82.1% were female with a mean age of 49.7 (SD, 14.3) years; 22.7% of the patients were hospitalized, and 5.3% died because of COVID-19 (coronavirus disease 2019). Argentina and Brazil had both 4% of mortality and Mexico 9.4%. In the multivariable analysis, older age (≥60 years; odds ratio [OR], 7.4; 95% confidence interval [CI], 4.6-12.4), male sex (OR, 1.5; 95% CI, 1.1-2.1), living in Mexico (OR, 3.0; 95% CI, 2.0-4.4), comorbidity count (1 comorbidity: OR, 1.5; 95% CI, 1.0-2.1), diagnosis of connective tissue disease or vasculitis (OR, 1.8; 95% CI, 1.3-2.4), and other diseases (OR, 2.6; 95% CI, 1.6-4.1) compared with inflammatory joint disease, high disease activity (OR, 4.2; 95% CI, 2.5-7.0), and treatment with glucocorticoids (OR, 1.9; 95% CI, 1.4-2.5) or rituximab (OR, 4.2; 95% CI, 2.7-6.6) were associated with mortality. CONCLUSIONS: Mortality in patients with IMIDs was particularly high in Mexicans. Ethnic, environmental, societal factors, and different COVID-19 mitigation measures adopted have probably influenced these results.

Factors associated with poor outcomes in SLE patients with COVID-19: Data from ReumaCoV-Brazil register.

OBJECTIVES: To evaluate factors associated with COVID-19 severity outcomes in patients with systemic lupus erythematosus (SLE). METHODS: This was a cross-sectional analysis of baseline data of a prospective, multi-stage cohort study-"The ReumaCoV Brazil"-designed to monitor patients with immune-mediated rheumatologic disease (IMRD) during the SARS-CoV-2 pandemic. SLE adult patients with COVID-19 were compared with those without COVID-19. SLE activity was evaluated by the patient global assessment (PGA) and SLE Disease Activity Index 2000 (SLEDAI-2K). RESULTS: 604 SLE patients were included, 317 (52.4%) with COVID-19 and 287 (47.6%) in the control group. SLE COVID-19 patients reported a lower frequency of social isolation and worked more frequently as health professionals. There was no difference in the mean SLEDAI-2K score between groups in the post-COVID-19 period (5.8 [8.6] vs. 4.5 [8.0]; p = 0.190). However, infected patients reported increased SLE activity according to the Patient Global Assessment (PGA) during this period (2.9 [2.9] vs. 2.3 [2.6]; p = 0.031. Arterial hypertension (OR 2.48 [CI 95% 1.04-5.91], p = 0.041), cyclophosphamide (OR 14.32 [CI 95% 2.12-96.77], p = 0.006), dyspnea (OR: 7.10 [CI 95% 3.10-16.23], p < 0.001) and discontinuation of SLE treatment medication during infection (5.38 [CI 95% 1.97-15.48], p = 0.002), were independently associated with a higher chance of hospitalization related to COVID-19. Patients who received telemedicine support presented a 67% lower chance of hospitalization (OR 0.33 [CI 95% 0.12-0.88], p = 0.02). CONCLUSION: Hypertension and cyclophosphamide were associated with a severe outcome, and telemedicine can be a useful tool for SLE patients with COVID-19.

Acute and Chronic Effects of Strength Training on Plasma Levels of Adipokines in Man.

Adipose tissue is specialized cells that produce and release adipokines. Exercise may modulate adipokine production in adipocytes. The aim of this longitudinal study was to evaluate the acute and chronic effects of strength training (ST) on plasma levels of adiponectin, leptin, and resistin. Twelve untrained young male participants (23.42±2.67 years) were selected. The training protocol consisted of 3 exercises, with 3 sets of 65% of 1RM (one-repetition maximum) with pause of 90 s between sets with duration of 5 s/repetition (2 s conc/3 s ecc), 3 times a week for 10 weeks. Blood was collected at four time points: before and after the first ST session and before and after the last ST session. The comparisons between adipokine levels before and after the same training session showed acute changes, while the comparisons between levels before or after the first session versus before or after the last session revealed chronic alterations. ST increased adiponectin levels after the first exercise session in comparison to levels before this session [50 952 (46 568-51 894) pg/mL vs. 52 981 (49 901-54 467) pg/mL, p=0.019]. Similar differences were observed for resistin levels, which were higher after the last session compared to before [4 214.4 (±829) pg/mL vs. pre-S30 2 251.3 (±462.2) pg/mL, p=0.0008] and in the comparison between after the last and after the first ST sessions [4 214.4 (±829.0) pg/mL vs. 1 563.7 (±284.8) pg/mL, p=0.004]. Leptin levels acutely changed in the last training session. ST produced acute and chronic changes in plasma adipokines.

Participating as a research team during the COVID-19 pandemic benefits mental health of undergraduate medical students in Brazil.

During the COVID-19 pandemic, undergraduate medical students (UMS) exposed to isolation, social distancing and complete or partial face-to-face educational activities interruption may present increased stress, depression and anxiety. This study was undertaken to evaluate if, during isolation, UMS involved in online group activities as investigators of a research project (volunteer group) would present better mental health than their colleagues, not involved in that research (control group). A Web-based survey, via the Google Forms platform, including details on demographic data, life habits, previous health conditions, worries with the COVID-19 pandemic, sleep pattern modifications and depression, anxiety and mental stress, using the DASS-21 (Depression, Anxiety and Stress Scale) was implemented from 20 July to 31 August 2020. Statistical analysis was performed using the SPSS version 20.0. A p-value <0.05 was significant. A total of 684 UMS were included, 228 as a volunteer group and 456 as a control group. Mean age was 23.15 (3.16) years. The groups were paired for age, gender, ethnicity, life habits and previous health conditions. Older age, male gender, participation in the research project, unchanged sleep pattern during the pandemic, lack of fear from getting the COVID-19 and lack of previous health conditions were associated with lower DASS21 scores (better mental health). Participating as investigators of a research project foreseeing frequent interaction with patients, colleagues and professors (other investigators) lead to better mental health during the COVID-19 quarantine in Brazil.

Incidence and risk factors for moderate/severe COVID-19 in rheumatic diseases patients on hydroxychloroquine: a 24-week prospective cohort.

OBJECTIVES: To evaluate the incidence of COVID-19 and its main outcomes in rheumatic disease (RD) patients on hydroxychloroquine (HCQ) compared to household cohabitants (HC). METHODS: This is a 24-week nationwide prospective multi-centre cohort with a control group without RD and not using HCQ. All participants were monitored through scheduled phone interviews performed by health professionals. Details regarding COVID-19 symptoms, and epidemiological, clinical, and demographic data were recorded on a specific web-based platform. COVID-19 was defined according to the Brazilian Ministry of Health criteria and classified as mild, moderate or severe. RESULTS: A total of 9,585 participants, 5,164 (53.9%) RD patients on HCQ and 4,421 (46.1%) HC were enrolled from March 29th, 2020 to September 30th, 2020, according to the eligibility criteria. COVID-19 confirmed cases were higher in RD patients than in cohabitants [728 (14.1%) vs. 427 (9.7%), p<0.001] in a 24-week follow-up. However, there was no significant difference regarding outcomes related to moderate/ severe COVID-19 (7.1% and 7.3%, respectively, p=0.896). After multiple adjustments, risk factors associated with hospitalisation were age over 65 (HR=4.5; 95%CI 1.35-15.04, p=0.014) and cardiopathy (HR=2.57; 95%CI 1.12-5.91, p=0.026). The final survival analysis demonstrated the probability of dying in 180 days after a COVID-19 diagnosis was significantly higher in patients over 65 years (HR=20.8; 95%CI 4.5-96.1) and with 2 or more comorbidities (HR=10.8; 95%CI 1.1-107.9 and HR=24.8; 95%CI 2.5-249.3, p=0.006, respectively). CONCLUSIONS: Although RD patients have had a higher COVID-19 incidence than individuals from the same epidemiological background, the COVID-19 severity was related to traditional risk factors, particularly multiple comorbidities and age, and not to underlying RD and HCQ.

How Did Patients Living With Immune-Mediated Rheumatic Diseases Face the Beginning of the COVID-19 Pandemic in Brazil? Results of the COnVIDa Study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has brought additional burden to patients living with immune-mediated rheumatic diseases (IMRDs), especially at the beginning of 2020, for which information for this population is lacking. METHODS: COnVIDa is a cross-sectional study on patients with IMRD from all regions of Brazil who were invited to answer a specific and customized Web questionnaire about how they were facing the COVID-19 pandemic, especially focusing on health care access, use of medications, and patient-reported outcomes related to IMRD activity. The questionnaire was applied from June 1 to 30, 2020. RESULTS: In total, 1722 of 2576 patients who answered the Web questionnaire were included in the final analysis. Participants were most frequently women, 56% were between 31 and 50 years old, and most (55%) has private health insurance. The most commonly reported IMRD was rheumatoid arthritis (39%), followed by systemic lupus erythematosus (28%). During the study period, 30.7% did not have access to rheumatology consultations, and 17.6% stopped chronic medications. Telemedicine was reported in 44.8% of patients. CONCLUSION: COnVIDa demonstrated a negative impact on health care access and treatment maintenance of patients living with IMRD during the COVID-19 pandemic. However, it also presented an uptake of telemedicine strategies. Data presented in this study may assist future coping policies.

Skeletal mass indices are inversely associated with metabolically unhealthy phenotype in overweight/obese and normal-weight men: a population-based cross-sectional study.

Muscle mass may play an important role in the metabolic profile of individuals with or without excess weight. Metabolic phenotypes classify individuals as healthy or unhealthy based on certain metabolic conditions. We investigated the association between skeletal mass indices (SMI) and the metabolically unhealthy phenotype in normal-weight and overweight/obese adults. A total of 660 adults aged 20 to 59 years were assessed by a population-based cross-sectional study. Muscle mass of the limbs or appendicular lean mass (ALM) adjusted for weight (SMIweight) and BMI (SMIBMI) was used to evaluate SMI. Logistic regression was employed to estimate the association between SMIweight, SMIBMI and metabolic phenotypes of normal-weight and overweight/obese individuals. Metabolically unhealthy individuals were older in both sexes. Metabolically unhealthy men had lower SMI values and higher fat percentage than metabolically healthy men. SMIweight was inversely associated with the metabolically unhealthy phenotype, both in normal-weight men (OR 0·49, 95 % CI 0·24, 0·99, P = 0·04) and in overweight/obese men (OR 0·32, 95 % CI 0·16, 0·64, P = 0·001). SMIBMI was inversely associated with the metabolically unhealthy phenotype in overweight/obese men (OR 0·36, 95 % CI 0·18, 0·72, P = 0·004), but not in normal-weight men (OR 0·70, 95 % CI 0·34, 1·43, P = 0·33). Among women, SMI showed no significant association with the phenotypes. In conclusion, the SMI are inversely associated with the metabolically unhealthy phenotype in men, especially among overweight/obese men.

Association between Skeletal Mass Indices and Metabolic Syndrome in Brazilian Adults.

INTRODUCTION: Skeletal muscle is the primary site of glucose uptake and its reduction would increase insulin resistance, which is a determinant factor for diseases such as type 2 diabetes mellitus, hypertension, and metabolic syndrome. However, the role of low skeletal muscle mass as a risk factor for metabolic syndrome and its association with cardiometabolic risk is still uncertain. We aimed to investigate the association between muscle mass (determined by different skeletal mass indices) and metabolic syndrome in Brazilian adults. METHODOLOGY: We conducted a cross-sectional population-based study with 689 adults of both sexes aged between 20 and 59 years. Data were collected through questionnaires and assessment of body composition through dual-energy X-ray absorptiometry and anthropometric, clinical, and biochemical measurements. RESULTS: Older individuals, obese and those with metabolic syndrome predominated in the highest tertile of skeletal mass index adjusted by height (SMIheight), whereas using skeletal mass index adjusted by weight (SMIweight) and skeletal mass index adjusted by body mass index (SMIBMI) these individuals were the majority in the lowest tertile of these indices. In men and women, the adjusted logistic regression model revealed that the highest tertile of SMIweight (odds ratio [OR]: 0.06; 95% confidence interval [CI]: 0.02-0.21 and OR: 0.27, 95% CI: 0.10-0.74) and SMIBMI (OR: 0.14, 95% CI: 0.05-0.37 and OR: 0.34, 95% CI: 0.12-0.94) were negatively associated with metabolic syndrome. On the other hand, the highest tertile of SMIheight was positively associated with metabolic syndrome in both sexes (OR: 4.17, 95% CI: 1.80-9.66 and OR: 6.15, 95% CI: 2.31-16.37, respectively in men and women). CONCLUSION: In adults, the muscle mass assessed from the skeletal mass index adjusted for body weight and body mass index is inversely associated with metabolic syndrome in both sexes.

Cultural Adaptation and Validation of the Methotrexate Intolerance Severity Score in Brazilian Portuguese for Adults With Rheumatoid Arthritis.

INTRODUCTION: The Methotrexate Intolerance Severity Score (MISS) questionnaire is used to identify intolerance to methotrexate (MTX), but it is not available in the Brazilian Portuguese language. OBJECTIVE: The aim of this study was to adapt and validate the MISS in Brazilian Portuguese. METHODS: The Brazilian Portuguese version of the MISS was developed following the Guidelines for the Process of Cross-cultural Adaptation of Self-report Measures. The new version was tested in 120 patients with rheumatoid arthritis. For the reliability assessment, the Cronbach α coefficient was used. The receiver operating characteristic curve was constructed with the objective of finding the best cutoff point for MTX intolerance and weighing the sensitivity and specificity. The concordance among the results was analyzed using the κ coefficient and factorial analysis with varimax rotation. RESULTS: This methodological study developed and applied a culturally acceptable Brazilian Portuguese version of the MISS. The MISS questionnaire presented internal consistency classified as "very good" because Cronbach α is equal to 0.83 (95% confidence interval, 0.79-0.87). The suitability of the data for factorial analysis was demonstrated using the Kaiser-Meyer-Olkin sample adequacy test (KMO = 0.723) and Bartlett sphericity test (χ2 = 499.98, p < 0.001). It was observed that a factorial analysis with 3 factors is preferred; the receiver operating characteristic curve of the MISS score was considered the cutoff point at 6 points (sensitivity 100% and specificity 89.4%). CONCLUSIONS: The Brazilian Portuguese version of the MISS is valid and reliable for the detection of MTX intolerance in clinical practice.

Renin-angiotensin system molecules are associated with subclinical atherosclerosis and disease activity in rheumatoid arthritis.

OBJECTIVES: To compare serum levels of RAS components in women with RA versus healthy females and to investigate the association between these molecules and subclinical atherosclerosis. METHODS: A cross-sectional study involving female RA patients without ischemic CVD. Disease activity was assessed using the DAS28 and the CDAI. IMT of the common carotid artery was evaluated by ultrasonography. Serum levels of Ang II, Ang-(1-7), ACE and ACE2 were determined by enzyme immunoassay. RESULTS: Fifty women with RA, mean 48.2 (7.3) years, were compared to 30 healthy women, paired by age. RA patients had higher plasma levels of Ang II (p < .01), Ang-(1-7) (p < .01), and ACE (p < .01) than controls. The ratios of ACE to ACE2 were higher in RA patients, whereas Ang II/Ang-(1-7) ratios were lower in RA patients. The presence of hypertension and the treatment with ACE inhibitors did not significantly modify serum levels of Ang II, Ang-(1-7), ACE and ACE2 in patients with RA. Seven RA patients had altered IMT, and eight patients exhibited atherosclerotic plaque. There was a negative correlation between ACE2 levels and IMT (p = .041). IMT positively correlated with age (p = .022), disease duration (p = .012) and overall Framingham risk score (p = .008). Ang II concentrations positively correlated with DAS28 (p = .034) and CDAI (p = .040). CONCLUSION: Patients with RA had an activation of the RAS, suggesting an association with disease activity and cardiovascular risk. Rheumatological key messages Imbalance of both RAS axes may be associated with cardiovascular risk and disease activity in rheumatoid arthritis. Ultrasonography of the carotid arteries can identify early, subclinical atherosclerotic disease in rheumatoid arthritis patients. Angiotensin-converting enzyme inhibition or angiotensin 1 receptor blockade may be beneficial for rheumatoid arthritis patients.

Fibroblast-like synoviocytes from fluid and synovial membrane from primary osteoarthritis demonstrate similar production of interleukin 6, and metalloproteinases 1 and 3.

OBJECTIVES: The objective of the study was to compare the production of metalloproteinases (MMP)-1, -3 and interleukin (IL)-6 by fibroblast-like synoviocytes (FLS) derived from synovial fluid (FD-FLS), and FLS derived from synovial tissue (TD-FLS) of patients with primary osteoarthritis (OA). The more accessible FD-FLS could facilitate the study of the role of these cells in OA pathophysiology. METHODS: MMP-1, MMP-3, and IL-6 levels were measured in the supernatant culture at baseline and 22 hours after stimulation with TNF-α and IL-1 ß. RESULTS: There was no difference at baseline between MMP-1, MMP-3 and IL-6 production by FD-FLS and TDFLS. Analogous to baseline, stimulation of FD-FLS and TD-FLS with IL-1ß and TNF-α did not result in difference on MMP-3 and IL-6 production. However, TD-FLS produced more MMP-1 than FD-FLS after stimulation with IL-1ß (p=0.01). Additionally, there was a positive correlation for production of MMP-1, MMP-3 and IL-6 between FD-FLS and TD-FLS (r=0.40 and p<0.0008; r=0.66 and p<0.0001; r=0.76 and p<0.0001, respectively). Supporting this statistical significant positive correlation, the Bland-Altman plotting, showed a homogeneous distribution of the values and low mean disagreement rates between all results of FD-FLS and TD-FLS (23.1%, 56.8% and 48.1%, respectively). CONCLUSIONS: Our data demonstrated functional similarity between FD-FLS and TD-FLS and support the use of a more accessible source of FLS for the study of the pathogenesis of joint destruction and therapeutic targets in primary OA.

Leptin as an obesity marker in rheumatoid arthritis.

The determination of excess of body fat mass provides a more suitable determinant of obesity in rheumatoid arthritis patients; however, body mass index (BMI) may not be accurate for the quantification of adiposity. To identify a marker of excess adiposity in women with rheumatoid arthritis (RA) using different methods for fat mass evaluation. A cross-sectional study was conducted in adult female patients with RA. Disease activity was assessed by DAS28-ESR, and obesity was determined by waist circumference (WC), BMI and dual-energy X-ray absorptiometry (DXA). The Human Bone Metabolism kit (Merck Millipore, Darmstadt, Alemanha) was used to determine the plasma levels of leptin, TNF-α, IL-6, and IL-1ß by quantification of serum proteins by technical microspheres (LUMINEX, TX, USA). Adiponectin was measured by enzyme-linked immunosorbent assay sandwich kit (R&D Systems, Minneapolis, MN, USA). Eighty-nine female patients, median age of 55.4 (± 11.6) years, and median disease duration of 16.4 (± 14.9) years were included. The frequency of obesity was 33.7% according to BMI, 89.9% with WC, and 56.1% with DXA. The median serum leptin concentration was the only marker that correlated with body fat percentage according to the three methods. This correlation was positive and not influenced by DAS28, C-reactive protein, erythrocyte sedimentation rate, or inflammatory cytokines levels (IL-6, TNF-α, IL-1ß). Analysis of ROC curves determined the cut-off point of 10.3 ng/mL of leptin as an obesity marker, with a sensitivity of 96.43% and a specificity of 23.81%. Serum leptin correlates positively with fat mass and is potentially useful in excess fat mass determination in clinical practice.

Negative impact of high cumulative glucocorticoid dose on bone metabolism of patients with myasthenia gravis.

This current study aimed to evaluate the frequency of low bone mass, osteopenia, and osteoporosis in patients with myasthenia gravis (MG) and to investigate the possible association between bone mineral density (BMD) and plasma levels of bone metabolism markers. Eighty patients with MG and 62 controls BMD were measured in the right femoral neck and lumbar spine by dual-energy X-ray absorptiometry. Plasma concentrations of osteocalcin, osteopontin, osteoprotegerin, tumor necrosis factor (TNF-α), interleukin (IL)-1ß, IL-6, dickkopf (DKK-1), sclerostin, insulin, leptin, adrenocorticotropic hormone, parathyroid hormone, and fibroblast growth factor (FGF-23) were analyzed by Luminex®. The mean age of patients was 41.9 years, with 13.5 years of length of illness, and a mean cumulative dose of glucocorticoids 38,123 mg. Patients had significant reduction in BMD of the lumbar, the femoral neck, and in the whole body when compared with controls. Fourteen percent MG patients had osteoporosis at the lumbar spine and 2.5% at the femoral neck. In comparison with controls, patients with MG presented lower levels of osteocalcin, adrenocorticotropic hormone, parathyroid hormone, sclerostin, TNF-α, and DKK-1 and higher levels of FGF-23, leptin, and IL-6. There was a significant negative correlation between cumulative glucocorticoid dose and serum calcium, lumbar spine T-score, femoral neck BMD, T-score, and Z-score. After multivariate analysis, higher TNF-α levels increased the likelihood of presenting low bone mass by 2.62. MG patients under corticotherapy presented low BMD and altered levels of bone markers.

Undifferentiated spondyloarthritis in a heterogeneous Brazilian population: an eight-year follow-up study.

The aim of the present study was to describe the outcomes of Brazilian patients with undifferentiated spondyloarthritis during an eight-year follow-up period. Patients fulfilling the European Spondyloarthritis (SpA) Study Group Classification Criteria were enrolled. Forty patients were seen at baseline, and 36 participated in the follow-up study. Twenty-three (58%) were female, and there were 24 (60%) African Brazilians enrolled. HLA-B27 was positive in 18 (45%) patients. At disease onset, the first presenting symptoms were pure peripheral manifestations in 26 (72.2%) patients. After the study period, mixed disease (axial + peripheral) predominated occurring in 25 (69.4%) patients. The Assessment of SpA International society (ASAS) classification criteria for axial SpA were fulfilled by 77% of patients, and the ASAS criteria for peripheral SpA were fulfilled by 59% of patients. After 2.5 years, 6 (16.7%) of the 36 patients fulfilled the modified New York Criteria for ankylosing spondylitis and 1 (2.7%) progressed to psoriatic arthritis. A total of 10 (27.8%) patients progressed to definite SpA during the eight-year study period. Buttock pain (p = 0.006, OR 10.55; 95% CI 2.00-65.90) and low-grade radiographic sacroiliitis (p = 0.025, OR = 11.50; 95% CI 1.33-83.39) at baseline were associated with definite SpA. Thus, in this Brazilian cohort, which had a predominance of female African-Brazilian patients, prevalent peripheral onset symptoms were followed by a high frequency of axial manifestations during the follow-up period. Evidence of clinical or radiological sacroiliitis was associated with progression to definite SpA.

Treatment of psoriatic arthritis with anti-TNF agents: a systematic review and meta-analysis of efficacy, effectiveness and safety.

We did a systematic review and meta-analysis on the efficacy and safety of the anti-TNF drugs adalimumab, etanercept, golimumab and infliximab used in psoriatic arthritis (PsA) adult treatment. Additionally, we present results of anti-TNF use in real life settings. We searched Embase, Medline, Cochrane Central and LILACS, from inception to 11/08/2013, for studies comparing anti-TNFs with each other or with controls. We included nine randomized controlled trials and six observational studies. ACR20, ACR50, PsARC and PASI75 responses were achieved by more users of anti-TNF than control after up to 24 weeks of treatment. More participants who used etanercept and infliximab achieved ACR70. After all patients originally randomized to anti-TNF or placebo had used anti-TNF for at least 24 weeks, we observed difference only with regard to ACR70 response. Radiographic end points were achieved by more patients in anti-TNF group, and they seem to be time dependent-the longer patients use the drug the better the results. Etanercept and infliximab had worse results on application site reactions, but in general anti-TNF drugs in the regimens studied were as safe as control/placebo. There seems to be no difference in efficacy and effectiveness among anti-TNFs, but superiority head-to-head studies are still needed. Meanwhile, other factors should be taken into account in the choice of medication, such as costs and patient convenience.

Malignancy in the Upadacitinib Clinical Trials for Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, and Non-radiographic Axial Spondyloarthritis.

INTRODUCTION: This article aims to describe malignancies in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), or non-radiographic axial spondyloarthritis (nr-axSpA) treated with upadacitinib (UPA) or active comparators. METHODS: This integrated safety analysis includes data from 11 phase 3 UPA trials across RA (6 trials), PsA (2 trials), AS (2 trials; one phase 2b/3), and nr-axSpA (1 trial). Treatment-emergent adverse events (TEAEs) were summarized for RA (pooled UPA 15 mg [UPA15], pooled UPA 30 mg [UPA30], adalimumab 40 mg [ADA], methotrexate monotherapy [MTX]), PsA (pooled UPA15, pooled UPA30, ADA), AS (pooled UPA15), and nr-axSpA (UPA15). TEAEs were reported as exposure-adjusted event rates (events/100 patient-years). RESULTS: Median treatment duration ranged from 1.0 to 4.0 years (with a maximum of 6.6 years in RA). Across treatments and indications, rates of malignancy excluding nonmelanoma skin cancer (NMSC) ranged from 0.2 to 1.1, while NMSC ranged from 0.0 to 1.4. In RA, rates of malignancy excluding NMSC were generally similar between UPA15, UPA30, ADA, and MTX (breast and lung cancer were the most common). In RA and PsA, Kaplan-Meier analyses revealed no differences in event onset of malignancy excluding NMSC with UPA15 versus UPA30 over time. In RA, NMSC rates were higher with UPA30 than UPA15; both UPA15 and UPA30 were higher than ADA and MTX. In PsA, rates of malignancy excluding NMSC and NMSC were generally similar between UPA15, UPA30, and ADA. In AS and nr-axSpA, malignancies were reported infrequently. Few events of lymphoma were reported across the clinical programs. CONCLUSION: Rates of malignancy excluding NMSC were generally similar between UPA15, UPA30, ADA, and MTX and were consistent across RA, PsA, AS, and nr-axSpA. A dose-dependent increased rate of NMSC was observed with UPA in RA.

ADHERENCE AND PERSISTENCE TO TREATMENT WITH INFLIXIMAB: ANALYSIS OF A PATIENT SUPPORT PROGRAM COHORT IN BRAZIL.

BACKGROUND: Monoclonal antibodies have proven efficacy in the management of several conditions and infliximab (IFX) is one of the most important drugs of the class. Some recent data have shown low rates of both persistence and adherence to several available biologics. OBJECTIVE: The objective of this study was to describe adherence and persistence rate to IFX treatment and also persistence in the patient support program (PSP), among patients diagnosed with inflammatory bowel diseases (IBD) or rheumatic diseases (RD) enrolled in the program of a large pharmaceutical company in Brazil. METHODS: Retrospective observational analysis using the PSP database. IBD or RD patients using IFX enrolled on the PSP database between September 2015 and August 2019 were retrospectively evaluated to identify the persistence rate and adherence and followed up until March 1, 2020. Patients were excluded if treatment start date was prior to program entry; first infusion prior to September 1st, 2015 or after August 31st, 2019; the patients did not started treatment; and patients with "OTHERS" in "Indication" field. Persistence was assessed considering both persistence in the program ("PSP persistence") and persistence on IFX in the PSP ("IFX persistence in the PSP"). PSP persistence was defined as the proportion of patients remaining in the program at 6, 12, 24, 36 and 48 months after initiating IFX. To determine IFX persistence in the PSP, censoring was defined at the time the patient left the program, died, or was lost to follow-up. Adherence to treatment was measured by medication possession ratio ((MPR) - All days supply / elapsed days from first prescription to last day of medication possession)). Descriptive statistics were initially used. Kaplan-Meier curve, the median time estimated by the survival function, Cox regression model, and restricted mean survival time (RMST) were used to evaluate the treatment persistence time at 24 months and the logistic regression model was performed aiming to identify variables associated with adherence (MPR ≥80%). RESULTS: A total of 10,233 patients were analyzed, 5,826 (56.9%) with the diagnosis of RD and 4,407 (43.1%) of IBD. At the end of the follow-up (median 9.1 months from PSP entry to the last infusion), persistence in the PSP was 65.6%, 48.2%, 31.0%, 20.7% and 13.1% at 6, 12, 24, 36 and 48 months, respectively. Considering persistence on IFX in the PSP, estimates were 93.7%, 87.8%, 77.0%, 62.4% and 53.0% at 6, 12, 24, 36 and 48 months, respectively. Variables associated with the risk of non-persistence were gender, country region and diagnosis of rheumatoid arthritis and ankylosing spondylitis. Median MPR was 94.2%, while the percentage of patients with MPR ≥80% was 91.0%. Variables associated with MPR≥80% were country region and diagnosis of Crohn's disease. CONCLUSION: Many patients leave the program without discontinuing IFX, since the 12-month persistence were very different between program and medication estimates, while high adherence rates were observed among patients enrolled in the PSP. Data highlights the benefits of a PSP.

Agreement and diagnostic differences among three definitions of sarcopenia in patients with chronic hepatitis C.

BACKGROUND: There is neither a gold standard definition nor a universal consensus to diagnose sarcopenia in patients with chronic hepatitis C. Thus, we aimed to compare the prevalence of sarcopenia and the agreement and discrepancies between European Working Group on Sarcopenia in Older People (EWGSOP1), EWGSOP2, and Foundation for the National Institutes of Health Biomarkers Consortium Sarcopenia Project (FNIH) definitions in chronic hepatitis C. METHODS: Dual-energy x-ray absorptiometry was used to assess muscle mass by quantifying appendicular lean mass (ALM) adjusted for squared height (ALM/ht2) or for body mass index (ALMBMI). Muscle function was evaluated by handgrip strength. Subjective Global Assessment was used to assess the nutrition status. RESULTS: This cross-sectional study included 103 outpatients (mean age, 50.6 ± 11.3 years; 33.0% with compensated cirrhosis). Sarcopenia prevalence was 8.7%, 9.7%, and 9.7%, according to EWGSOP1, EWGSOP2, and FNIH definitions, respectively. There was neither a sex- nor a liver disease severity-specific difference in the prevalence of sarcopenia between the criteria applied. Sixteen (15.5%) patients fulfilled at least one of these criteria, and 3 out of 16 (18.8%) simultaneously had sarcopenia by consensus of the three criteria. Sarcopenic obesity was identified in 9 out of 16 (56.3%) patients, and 6 out of 9 (66.7%) of these only met FNIH consensus. CONCLUSIONS: In patients without cirrhosis or with compensated cirrhosis, and with chronic hepatitis C, the agreement between EWGSOP1 and EWGSOP2 classifications was substantial for sarcopenia diagnosis. Concerning EWGSOP and FNIH criteria, a fair agreement and limited overlap were found in these patients.
