34902577 Dietary recommendations of the French Society for Rheumatology for patients with chronic i 2022 Mar This article presents the 1st set of dietary recommendations of the French Society for Rheumatology for patients suffering from chronic inflammatory rheumatic diseases (IRD) made by a working group consisting of 12 rheumatology experts, 3 physician nutrition specialists, 1 internal medicine specialist, 1 registered dietician and 3 representatives from patient associations. This group relied on a systematic literature review and on expert opinions, while taking into consideration not only the joint effects of diet in IRD but also the extra-articular ones. Eight general principles and nine recommendations were established. The general principles emphasize that nutritional advice is not a substitute for pharmacological treatment of IRD and that it is an integral part of the patients' overall care, which could help the patient actively participate in their care. The recommendations propose supporting weight loss in subjects who are overweight or obese, a Mediterranean-type diet and supplementation in polyunsaturated fatty acids, mainly omega-3. Conversely, gluten-free diets (in the absence of celiac disease), vegetarian/vegan diets, fasting and elimination of dairy products should not be proposed. Supplementation with vitamins or trace elements is not indicated for controlling chronic IRD activity, while the use of probiotics or spices is not recommended given the limited or disparate data.
35603866 Eltrombopag improves refractory thrombocytopenia in patients with Sjögren's syndrome. 2022 Apr INTRODUCTION: Eltrombopag, a kind of thrombopoietin (TPO) receptor agonist, plays the role on the megakaryocyte to activate the platelet production and rapidly increase the number of circulating platelets in patients with primary immune thrombocytopenia (ITP). Eltrombopag provides an opportunity for rapid tapering and/or cessation of corticosteroid therapy. However, it is not clear about the platelet response to Eltrombopag in ITP associated with Sjögren's Syndrome(SS). METHODS: A retrospective research was conducted on the clinical course of three patients, each with ITP secondary to SS, and initially received therapy of corticosteroids or other immunomodulatory. They took this drug for bleeding diseases. Referring to the description, Eltrombopag was prescribed and adjusted with an initial dose of 25 mg daily, then weekly, then monthly according to the monitoring of platelet counts. RESULTS: All patients maintained a satisfactory level of platelet counts (>100,000/mm(3) for >2 years) following corticosteroid withdrawal. Meanwhile, Eltrombopag was well-tolerated, and there were no adverse effects, such as thrombotic events. CONCLUSIONS: Eltrombopag is effective and safe for patients with ITP associated with SS during corticosteroid withdrawal. Thus it may be a crucial therapeutic strategy for reducing corticosteroid-related side effects in SS patients with ITP.
35481450 Short interruptions of TNF-inhibitor treatment can be associated with treatment failure in 2022 Apr 28 INTRODUCTION: The prevalence of immune-mediated diseases has increased in the past decades and despite the use of biological treatments all patients do not achieve remission. The aim of this study was to characterise the reasons for short interruptions during treatment with two commonly used TNF-inhibitors infliximab and adalimumab and to analyse the possible effects of the interruptions on immunisation and switching the treatment. MATERIAL AND METHODS: This case-control study was based on retrospective analyses of patient records and a questionnaire survey to clinicians. A total of 370 patients (194 immunised cases and 172 non-immunised controls, 4 excluded) were enrolled from eight hospitals around Finland. Eleven different diagnoses were represented, and the largest patient groups were those with inflammatory bowel or rheumatic diseases. RESULTS: Treatment interruptions were associated with immunisation in patients using infliximab (p < .001) or adalimumab (p < .000001). Patients with treatment interruptions were more likely to have been treated with more than one biological agent compared to those without treatment interruptions. This was particularly prominent among patients with a rheumatic disease (p < .00001). The most frequent reason for a treatment interruption among the cases was an infection, whereas among the control patients it was remission. The median length of one interruption was one month (interquartile range 1-3 months). CONCLUSION: Our results suggest that the interruptions of the treatment with TNF-inhibitors expose patients to immunisation and increase the need for drug switching. These findings stress the importance of careful judgement of the need for a short interruption in the biological treatment in clinical work, especially during non-severe infections.
35266034 Differential efficacy of TNF inhibitors with or without the immunoglobulin fragment crysta 2022 Mar 10 Rheumatoid factor (RF) binds to the fragment crystallizable (Fc) portion of immunoglobulin. It could bind to the Fc portion of anti-TNF inhibitors (TNFi) and attenuate the clinical efficacy. We tried to determine whether the therapeutic efficacy of TNFi with Fc might be lower than that of TNFi without Fc in rheumatoid arthritis (RA) patients with high titres of RF. The Kansai Consortium for Well-being of Rheumatic Disease Patients (ANSWER) cohort is an observational multi-center registry of patients with RA in the Kansai district of Japan. RA patients treated with TNFi were included and divided into two groups based on the structural characteristics between TNFi with Fc (infliximab, adalimumab, golimumab, and etanercept) and TNFi without Fc (certolizumab pegol). Patients were classified into 4 groups according to RF titre quartiles. The sequential disease activity score in 28 joints using erythrocyte sedimentation rate (DAS28-ESR) was compared by Mann-Whitney U test between TNFi with and without Fc in each RF titre group. Multiple linear regression analysis was used to analyze the effect of TNFi without Fc for the change of DAS28-ESR adjusted after potential confounders. A total of 705 RA patients were classified into four groups (RF(1); RF 0-15.0 IU/mL, RF(2); 15.0-55.0, RF(3); 55.0-166, RF(4); 166-7555). In RF(4), RA patients treated with TNFi without Fc had a significantly lower DAS28-ESR than those treated with TNFi with Fc [3.2 (2.3-4.2) vs. 2.7 (2.0-3.0)] after 12 months. This effect of TNFi without Fc for the change of DAS28-ESR after 12 months treatment retained in multivariate analysis in RF(4). TNFi without Fc may be more efficacious than TNFi with Fc in RA patients with high RF titres.
35350717 Lessons from experiences of accessing healthcare during the pandemic for remobilizing rheu 2022 OBJECTIVES: To understand the impact of the coronavirus disease 2019 pandemic on access to healthcare services for patients with inflammatory and non-inflammatory musculoskeletal (MSK) conditions. METHODS: Three established cohorts that included individuals with axial SpA, psoriatic arthritis and MSK pain completed a questionnaire between July and December 2020. In parallel, a subset of individuals participated in semistructured interviews. RESULTS: A total of 1054 people (45% female, median age 59 years) were included in the quantitative analyses. Qualitative data included 447 free-text questionnaire responses and 23 interviews. A total of 57% of respondents had tried to access care since the start of the UK national lockdown. More than a quarter reported being unable to book any type of healthcare appointment. General practice appointments were less likely to be delayed or cancelled compared with hospital appointments. Younger age, unemployment/health-related retirement, DMARD therapy, anxiety or depression and being extremely clinically vulnerable were associated with a greater likelihood of attempting to access healthcare. People not in work, those reporting anxiety or depression and poorer quality of life were less likely to be satisfied with remotely delivered healthcare. Participants valued clear, timely and transparent care pathways across primary care and specialist services. While remote consultations were convenient for some, in-person appointments enabled physical assessment and facilitated the development and maintenance of clinical relationships with care providers. CONCLUSIONS: We identified patient factors that predict access to and satisfaction with care and aspects of care that patients value. This is important to inform remobilisation of rheumatology services to better meet the needs of patients.
34989169 Prevalence of Frailty in Ankylosing Spondylitis, Psoriatic Arthritis, and Rheumatoid Arthr 2022 Apr OBJECTIVE: Frailty is associated with disability and mortality independent of age. Although studies have evaluated frailty in rheumatoid arthritis (RA), information on the prevalence of frailty in ankylosing spondylitis (AS) and psoriatic arthritis (PsA) is limited. We aimed to determine the prevalence of frailty in AS and PsA and to evaluate whether characteristics known to be associated with frailty, including anxiety, differ among these three types of inflammatory arthritis. METHODS: We performed a cross sectional study of Centers for Medicare & Medicaid Services (CMS) beneficiaries aged 65 years or older with AS, PsA, or RA enrolled in 2014. We operationalized frailty using a validated claims-based frailty index. We also explored the prevalence of frailty among CMS beneficiaries younger than age 65 years with work disability, a younger population that also may be at risk of frailty. RESULTS: The prevalence of frailty in beneficiaries aged 65 years or older with AS and PsA was 45.2% and 46.7%, respectively, significantly lower than in RA (65.9%, P < 0.05). The prevalence of frailty in beneficiaries less than 65 years old was much lower overall, though still highest in RA; 11.7%, 4.4%, and 7.0% in RA, AS, and PsA, respectively (P < 0.05). Anxiety was significantly associated with frailty in subjects of all ages, particularly among those less than 65 years old (P < 0.05). CONCLUSION: Almost half of beneficiaries with AS or PsA aged 65 years old or older were frail, higher than in younger disabled beneficiaries. Further studies are needed to understand the risks of developing frailty in these diseases. Frailty was associated with anxiety, particularly in the younger age groups.
35279812 Responding to and Driving Change in Rheumatology: Report from the 12th International Immun 2022 Apr The coronavirus disease 2019 (COVID-19) pandemic has accelerated changes to rheumatology daily clinical practice. The main goal of the 12th International Immunology Summit, held 25-26 June, 2021 (virtual meeting), was to provide direction for these active changes rather than undergoing change reactively in order to improve patient outcomes. This review describes and explores the concept of change in rheumatology clinical practice based on presentations from the Immunology Summit. Many of the changes to rheumatology practice brought about by the COVID-19 pandemic may be considered as having a positive impact on disease management and may help with the long-term development of more patient-focused treatment. Rheumatologists can contribute key knowledge regarding the use of immunosuppressive agents in the context of the pandemic, and according to the European League Against Rheumatism, they should be involved in any multidisciplinary COVID-19 guideline committees. New technologies, including telemedicine and artificial intelligence, represent an opportunity for physicians to individualise patient treatment and improve disease management. Despite major advances in the treatment of rheumatic diseases, the efficacy of available disease-modifying anti-rheumatic drugs (DMARDs) remains suboptimal and data regarding serological biomarkers are limited. Synovial tissue biomarkers, such as CD68(+) macrophages, have shown promise in elucidating pathogenesis and targeting treatment to the individual patient. In spondyloarthritis (SpA) or psoriatic arthritis (PsA), information regarding the effectiveness of the available agents with different mechanisms of action may be integrated to manage patients using a treat-to-target approach. Early diagnosis of SpA and PsA is important for optimisation of treatment response and long-term outcomes. Improving our understanding of disease pathogenesis and practice methods may help reduce diagnostic delays, thereby optimising disease outcomes in patients with rheumatic diseases.
34464029 Upadacitinib pharmacokinetics and exposure-response analyses of efficacy and safety in pso 2022 Jan Upadacitinib is an oral Janus kinase inhibitor approved for the treatment of rheumatoid arthritis (RA) and recently approved by the European Medicines Agency for the treatment of psoriatic arthritis (PsA). The efficacy and safety profile of upadacitinib in PsA have been established in the SELECT-PsA program in two global phase III studies, which evaluated upadacitinib 15 and 30 mg q.d. The analyses described here characterized upadacitinib pharmacokinetics and exposure-response relationships for efficacy and safety endpoints using data from the SELECT-PsA studies. Upadacitinib pharmacokinetics in patients with PsA were characterized through a Bayesian population analysis approach and were comparable to pharmacokinetics in patients with RA. Exposure-response relationships for key efficacy and safety endpoints were characterized using data from 1916 patients with PsA. The percentage of patients achieving efficacy endpoints at week 12 (American College of Rheumatology [ACR]50 and ACR70), 16 and 24 (sIGA0/1) increased with increasing upadacitinib average plasma concentration over a dosing interval, whereas no clear exposure-response trend was observed for ACR20 at week 12 or ACR20/50/70 at week 24 within the range of plasma exposures evaluated in the phase III PsA studies. No clear trends for exposure-response relationships were identified for experiencing pneumonia, herpes zoster infection, hemoglobin less than 8 g/dl, lymphopenia (grade ≥ 3), or neutropenia (grade ≥ 3) after 24 weeks of treatment. Shallow relationships with plasma exposures were observed for serious infections and hemoglobin decrease greater than 2 g/dl from baseline at week 24. Based on exposure-response analyses, the upadacitinib 15 mg q.d. regimen is predicted to achieve robust efficacy in patients with PsA and to be associated with limited incidences of reductions in hemoglobin or occurrence of serious infections.
35081991 Rapid monitoring of health services use following a policy to switch patients from origina 2022 Jan 27 BACKGROUND: Drug coverage policies that incentivize switching patients from originator to biosimilar products may result in significant health care savings. Our study aimed to detect early impacts on health services utilization following a mandated switch from originator to biosimilar etanercept in British Columbia (BC), Canada. METHODS: We conducted a prospective, population-based cohort study using linked administrative health data from BC (2010-2020). The policy cohort consisted of patients with inflammatory arthritis who used originator etanercept in 2019, prior to BC's Biosimilars Initiative switching policy. Three historical cohorts included patients with inflammatory arthritis who used originator etanercept in the years 2016, 2017, and 2018. We compared the daily cumulative incidences of drug refills and outpatient and inpatient services between the policy and historical cohorts. A likelihood ratio sustained (≥ 31 days) at 7.1 or higher compared with the null hypothesis was chosen a priori as a threshold for a potential impact of the policy. RESULTS: Each cohort contained between 1694 and 1963 patients. We detected several potential impacts: 1) a transient increase in etanercept refills between months three and eight (cumulative incidence difference of + 3.0%); 2) an anticipated increase in visits to physicians of any specialty between months three and eight (+ 2.6%); and 3) an anticipated increase in visits to a rheumatologist from the end of month three onwards (+ 12.8%). The policy had no impact on incidences of switching to a different biologic antirheumatic drug, visits to emergency departments, or admissions to hospitals. CONCLUSIONS: Only transient and/or anticipated increases in drug refills and physician visits were observed during the study period. Additional research on clinical outcomes is recommended to strengthen the evidence that no long-term unintended negative health impacts are associated with BC's Biosimilars Initiative [switching policy].
35432367 Lipids in Liver Failure Syndromes: A Focus on Eicosanoids, Specialized Pro-Resolving Lipid 2022 Lipids are organic compounds insoluble in water with a variety of metabolic and non-metabolic functions. They not only represent an efficient energy substrate but can also act as key inflammatory and anti-inflammatory molecules as part of a network of soluble mediators at the interface of metabolism and the immune system. The role of endogenous bioactive lipid mediators has been demonstrated in several inflammatory diseases (rheumatoid arthritis, inflammatory bowel disease, atherosclerosis, cancer). The liver is unique in providing balanced immunotolerance to the exposure of bacterial components from the gut transiting through the portal vein and the lymphatic system. This balance is abruptly deranged in liver failure syndromes such as acute liver failure and acute-on-chronic liver failure. In these syndromes, researchers have recently focused on bioactive lipid mediators by global metabonomic profiling and uncovered the pivotal role of these mediators in the immune dysfunction observed in liver failure syndromes explaining the high occurrence of sepsis and subsequent organ failure. Among endogenous bioactive lipids, the mechanistic actions of three classes (eicosanoids, pro-resolving lipid mediators and lysophospholipids) in the pathophysiological modulation of liver failure syndromes will be the topic of this narrative review. Furthermore, the therapeutic potential of lipid-immune pathways will be described.
34782084 Immune-based Therapies-What the Emergency Physician Needs to Know. 2022 Feb Immunotherapy is a treatment modality that has a broad and rapidly growing range of applications to treat both chronic and acute diseases, including rheumatoid arthritis, Crohn disease, cancer, and COVID-19. Emergency physicians must be aware of the breadth of applications and be able to consider the effects of immunotherapies when patients on these treatments present to the hospital. This article provides a review of the mechanisms of action, indications for use, and potential complications of immunotherapy treatments that are relevant in the emergency care setting.
34789453 Severe delayed hypersensitivity reactions to IL-1 and IL-6 inhibitors link to common HLA-D 2022 Mar OBJECTIVES: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe, delayed hypersensitivity reaction (DHR). We observed DRESS to inhibitors of interleukin 1 (IL-1) or IL-6 in a small group of patients with Still's disease with atypical lung disease. We sought to characterise features of patients with Still's disease with DRESS compared with drug-tolerant Still's controls. We analysed human leucocyte antigen (HLA) alleles for association to inhibitor-related DHR, including in a small Kawasaki disease (KD) cohort. METHODS: In a case/control study, we collected a multicentre series of patients with Still's disease with features of inhibitor-related DRESS (n=66) and drug-tolerant Still's controls (n=65). We retrospectively analysed clinical data from all Still's subjects and typed 94/131 for HLA. European Still's-DRESS cases were ancestry matched to International Childhood Arthritis Genetics Consortium paediatric Still's cases (n=550) and compared for HLA allele frequencies. HLA association also was analysed using Still's-DRESS cases (n=64) compared with drug-tolerant Still's controls (n=30). KD subjects (n=19) were similarly studied. RESULTS: Still's-DRESS features included eosinophilia (89%), AST-ALT elevation (75%) and non-evanescent rash (95%; 88% involving face). Macrophage activation syndrome during treatment was frequent in Still's-DRESS (64%) versus drug-tolerant Still's (3%; p=1.2×10(-14)). We found striking enrichment for HLA-DRB1*15 haplotypes in Still's-DRESS cases versus INCHARGE Still's controls (p=7.5×10(-13)) and versus self-identified, ancestry-matched Still's controls (p=6.3×10(-10)). In the KD cohort, DRB1*15:01 was present only in those with suspected anakinra reactions. CONCLUSIONS: DRESS-type reactions occur among patients treated with IL-1/IL-6 inhibitors and strongly associate with common HLA-DRB1*15 haplotypes. Consideration of preprescription HLA typing and vigilance for serious reactions to these drugs are warranted.
35327043 Self-Efficacy of Saudi Patients with Autoimmune Diseases in Managing Hydroxychloroquine-In 2022 Mar 17 Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are common autoimmune diseases (AD) that affect joints and have multi-organ involvement that results in disability, morbidity, and increased mortality. Both conditions are known to cause a wide range of ocular manifestations. Antimalarial drugs, mainly hydroxychloroquine (HCQ), are among the treatment options for AD that is uniquely characterized by retinopathy as a main side effect. This study examines self-efficacy levels in autoimmune disease patients who were or are currently treated with HCQ and related factors such as patient education, communication with the physician, self-education, and ability to cope with the disease.
34842362 Outpatient Use of Antimicrobials in Patients With Rheumatoid Arthritis Before and After Tr 2022 Feb OBJECTIVE: The objective of this study was to investigate the effect of tumor necrosis factor α inhibitor (TNFi) initiation on the use of antimicrobials among biologic-naïve patients with rheumatoid arthritis (RA). METHODS: Information on all biologic-naïve patients with RA was extracted from ICEBIO, a nationwide registry. Each patient was matched on age, sex, and calendar time to five randomly selected individuals from the general population. All filled antimicrobial and glucocorticoid prescriptions in the 2 years before and after initiation of the first TNFi were extracted from the Prescription Medicines Register. Prescriptions were quantified by using the number of filled prescriptions (NP) and defined daily doses. RESULTS: We extracted information on 359 patients with RA and 1795 comparators. During the 24 months before initiating treatment with TNFi, patients with RA received more prescriptions for antimicrobials than their matched general population comparators (mean ± SD: 2.8 ± 3.4 vs 1.6 ± 2.7; P < 0.001). The 24-month mean NP for patients with RA increased to 3.5 ± 3.9 (P < 0.001) after initiating TNFi: antibiotics, 2.6 ± 3.2 to 3.2 ± 3.5 (P < 0.001); antivirals, 0.06 ± 0.5 to 0.16 ± 0.7 (P = 0.004); and antimycotics, 0.14 ± 0.5 to 0.22 ± 0.9 (P = 0.06). The 12-month mean NP was highest in the second year after TNFi initiation (1.9 ± 2.4). No association was found between NP and glucocorticoids, age, body mass index, or pre-TNFi Disease Activity Score 28-joint count and C-reactive protein. CONCLUSION: Patients with RA on TNFi are more commonly treated for infections in the outpatient settings than previously reported. Patients are prescribed more antimicrobials in the 2 years preceding TNFi initiation than the general population, and this use further increases after initiation of TNFi. In contrast to what is reported for infections requiring hospitalization, outpatient antimicrobial use remained elevated for at least 2 years.
35214790 Homologous and Heterologous Anti-COVID-19 Vaccination Does Not Induce New-Onset Formation 2022 Feb 18 The COVID-19 pandemics has caused the death of almost six million people worldwide. In order to establish collective immunity, the first vaccines that were approved in Germany were the vector virus-based vaccine Vaxzevria and the mRNA vaccines Comirnaty and Spikevax, respectively. As it was reported that SARS-CoV-2 can trigger autoimmunity, it is of significant interest to investigate whether COVID-19 vaccines evoke the formation of autoantibodies and subsequent autoimmunity. Here, we analyzed immune responses after different vaccination regimens (mRNA/mRNA, Vector/Vector or Vector/mRNA) with respect to anti-SARS-CoV-2-specific immunity and the development of autoantibodies well known for their appearance in distinct autoimmune diseases. We found that anti-SARS-CoV-2 antibody levels were 90% lower after Vector/Vector vaccination compared to the other vaccinations and that Vector/mRNA vaccination was more effective than mRNA/mRNA vaccination in terms of IgM and IgA responses. However, until 4 months after booster vaccination we only detected increases in autoantibodies in participants with already pre-existing autoantibodies whereas vaccinees showing no autoantibody formation before vaccination did not respond with sustained autoantibody production. Taken together, our study suggests that all used COVID-19 vaccines do not significantly foster the appearance of autoantibodies commonly associated with lupus erythematodes, rheumatoid arthritis, Celiac disease and antiphospholipid-syndrome but provide immunity to SARS-CoV-2.
35461008 Deciphering mechanisms and implications of bacterial translocation in human health and dis 2022 Apr 20 Significant increases in potential microbial translocation, especially along the oral-gut axis, have been identified in many immune-related and inflammatory diseases, such as inflammatory bowel disease, colorectal cancer, rheumatoid arthritis, and liver cirrhosis, for which we currently have no cure or long-term treatment options. Recent advances in computational and experimental omics approaches now enable strain tracking, functional profiling, and strain isolation in unprecedented detail, which has the potential to elucidate the causes and consequences of microbial translocation. In this review, we discuss current evidence for the detection of bacterial translocation, examine different translocation axes with a primary focus on the oral-gut axis, and outline currently known translocation mechanisms and how they adversely affect the host in disease. Finally, we conclude with an overview of state-of-the-art computational and experimental tools for strain tracking and highlight the required next steps to elucidate the role of bacterial translocation in human health.
35522353 Inflammatory markers and risk factors of RA patients with depression and application of di 2022 May 6 To evaluate the association of inflammatory markers and depression in RA patients and the risk factors in RA with depression, a cross-sectional study was conducted in a cohort of RA patients from southern China.Two hundred-fifteen RA patients were enrolled. The demographic and disease-related characteristics were recorded and inflammatory markers in sera were measured. RA patients were guided to fill out PHQ-9 scale by themselves, the psychological state was evaluated by psychiatry experts and graded according to the HAMD-17 scale. The consistency of the two scales in judging depression was evaluated. RA with depression group had HAMD-17 scores greater than 7. The levels of CRP, ESR, fibrinogen, SAA, IL-2, IL-6, TNF-α, IFN-γ, IL-4, and IL-10 were measured and compared. Logistic regression analysis was performed to find the risk factors of RA with different depression levels. One hundred-five (48.84%) RA patients had HAMD-17 scores greater than 7. High consistency was found between HAMD-17 and PHQ-9 in predicting depression. RA patients with depression were more likely to have tender joints, lower income, no employment, higher disease activity, joint deformities and glucocorticoid treatment. The depressed RA patients had higher serum levels of IL-6, CRP, fibrinogen, and SAA. IL-6, CRP, fibrinogen, and SAA were positive correlated with depression in RA patients. PHQ-9 can replace HAMD-17 in clinical application to judge depression.
35458425 Epidemiology of the Epstein-Barr Virus in Autoimmune Inflammatory Rheumatic Diseases in No 2022 Mar 27 The present study aimed to describe the seroprevalence infection, Epstein-Barr virus (EBV) genotypes, relate the infection's profile with the epidemiological and corticotherapy data of patients with Autoimmune inflammatory rheumatic diseases (AIRD). A cross-sectional study was carried out with 139 individuals, 92 with systemic lupus erythematosus (SLE), 27 with rheumatoid arthritis (RA) and 20 with other autoimmune diseases, who were undergoing clinical follow-up in Brazil. Serological tests for the detection of EBV anti-VCA IgM and IgG antibodies, as well as the amplification of a segment of the EBV EBNA-3c gene by conventional PCR were performed to identify the infection and the viral subtype. The Epstein-Barr nuclear antigen 3 (EBNA3C) gene participates of maintenance of viral latency and infected B-lymphocytes immortalization by unclear signaling cascades. The association of active/latent EBV infection with EBV infection profile was assessed by Fisher's exact test and multiple logistic regression. The seroprevalence of EBV anti-VCA IgG was 100%, while that of anti-VCA IgM was 1.43% (2/139). Active-phase infection was confirmed by the presence of EBV DNA in 40.29% of the population evaluated (56/139), with 45.65% (42/92) in SLE, 25.92% (7/27) in the RA and in 35% (7/20) in other autoimmune diseases. It was observed that individuals with SLE had a higher prevalence of active/lytic EBV infection and that oral corticosteroid therapy at a dose lower than 20 mg/day increased the risk of EBV activity by up to 11 times. Only the presence of EBV-1 was identified. Thus, EBV lytic infection was higher in individuals with SLE when compared to other autoimmune diseases with rheumatologic involvement and the lytic activity of the virus precedes corticosteroid-induced immunosuppression.
35044468 Secular Trends in Musculoskeletal Rehabilitation Needs in 191 Countries and Territories Fr 2022 Jan 4 IMPORTANCE: It is hard for policy makers and health professionals to develop musculoskeletal rehabilitation strategies because secular trends for musculoskeletal rehabilitation by region and country remain unknown. OBJECTIVE: To evaluate the secular trends in global musculoskeletal rehabilitation needs by sex, age, region, country, and health condition. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included data from 191 countries and territories from the World Health Organization Rehabilitation Need Estimator between January 1, 1990, and December 31, 2019. Data analyses were performed from February to May 2021. MAIN OUTCOMES AND MEASURES: Prevalence and years lived with disability (YLDs) of musculoskeletal disorders in need of rehabilitation, overall and by sex, age, region, country, and health condition. Trends in rehabilitation needs were evaluated by the estimated annual percentage changes (EAPCs) in age-standardized rates. Pearson correlation analysis was used to examine the associations between EAPCs and the age-standardized rates in 1990. The associations between the age-standardized rates and universal health coverage (UHC) effective coverage index were assessed by fitting a restricted cubic spline in a linear model. RESULTS: From 1990 to 2019, the global number of prevalent cases of musculoskeletal disorders in need of rehabilitation increased from 1060.6 (95% uncertainty interval [UI], 1009.1-1116.4) million to 1713.6 (95% UI, 1632.4-1800.4) million, with a steady increase in the number of YLDs from 93.9 (95% UI, 67.7-123.6) million to 149.0 (95% UI, 107.5-198.6) million. Overall, 55 countries and territories (28.8%) had annual increase in age-standardized prevalence rates, and 18 countries and territories (9.4%) had annual increase in YLD rates. The global age-standardized prevalence and YLD rates of musculoskeletal disorders decreased annually with EAPCs of 0.34 (95% CI, -0.37 to -0.31) and 0.42 (95% CI, -0.51 to -0.32), respectively. Specifically, the global age-standardized prevalence and YLD rates decreased for low back pain (prevalence: EAPC, -0.52; 95% CI, -0.57 to -0.47; YLD: EAPC, -0.52; 95% CI, -0.66 to -0.37), fractures (prevalence: EAPC, -0.35; 95% CI, -0.41 to -0.30; YLD: EAPC, -0.42; 95% CI, -0.65 to -0.19), other injuries (prevalence: EAPC, -0.75; 95% CI, -0.82 to -0.68; YLD: EAPC, -1.04; 95% CI, -1.38 to -0.71), and amputation (prevalence: EAPC, -0.64; 95% CI, -0.73 to -0.55; YLD: EAPC, -1.13; 95% CI, -1.60 to -0.65). The age-standardized prevalence rate decreased for neck pain (EAPC, -0.10; 95% CI, -0.18 to -0.02) but increased for osteoarthritis (EAPC, 0.13; 95% CI, 0.06-0.19) and rheumatoid arthritis (EAPC, 0.37; 95% CI, 0.04-0.70). In contrast, the age-standardized YLD rates remained stable for neck pain (EAPC, -0.09; 95% CI, -0.35 to 0.16), osteoarthritis (EAPC, 0.14; 95% CI, -0.14 to 0.42), and rheumatoid arthritis (EAPC, 0.38; 95% CI, -0.40 to 1.16). The age-standardized prevalence rate of neck pain decreased faster in male individuals, with an EAPC of -0.10 (95% CI, -0.19 to -0.02), while the age-standardized prevalence rate of low back pain decreased faster in female individuals, with an EAPC of -0.55 (95% CI, -0.60 to -0.51). EAPCs were significantly associated with the baseline age-standardized rates (prevalence: ρ = -0.49; P < .001; YLD: ρ = -0.55; P < .001), except for those of neck pain and rheumatoid arthritis. Excess rehabilitation needs were observed in countries with both higher and lower UHC effective coverage indexes (prevalence: β = 749.04; SE, 288.52; P = .01; YLD: β = 49.70; SE, 22.89; P = .03). CONCLUSIONS AND RELEVANCE: In this cross-sectional study, substantial increases in musculoskeletal rehabilitation needs were found across locations, suggesting rehabilitation needs have become a global health concern. Mitigating risk factors, strengthening rehabilitation in primary health care, and allocating sufficient funds are encouraged to satisfy rehabilitation needs.
35383559 Disease activity in patients with rheumatoid arthritis increases serum levels of apolipopr 2022 Apr 6 OBJECTIVES: Rheumatoid arthritis (RA) has been unequivocally associated with an increased burden of accelerated atherosclerosis, which, at least in part, is a consequence of the inflammation present in the disease. Apolipoprotein C-III (ApoC3) is a key molecule in triglycerides metabolism that has been linked to cardiovascular (CV) disease. Our objective was to study how ApoC3 is related to the characteristics of RA, paying special attention to its relationship with the inflammatory activity of the disease. METHODS: Cross-sectional study that included 430 patients with RA. In these patients, data related to the disease, classic CV risk factors, complete lipid profile, and serum ApoC3 levels were evaluated. A multivariable regression analysis was performed to study the relationship of the characteristics of RA with ApoC3. RESULTS: Abdominal circumference, obesity, type 2 diabetes, and circulating triglycerides were significantly associated with higher ApoC3 serum levels. Furthermore, C-reactive protein and erythrocyte sedimentation rate, as well as the disease activity score -DAS28- were significantly related to a higher circulating ApoC3 after multivariable analysis. Patients included in the moderate or high disease activity groups had higher ApoC3 serum levels compared to those in remission (beta coefficient 1.28 [95% confidence interval 0.16-2.39] mg/dl, p=0.025) when adjusting for confounders. The use of prednisone, disease-modifying anti-rheumatic drugs and anti-tumour necrosis factor therapies was associated with lower values of ApoC3. CONCLUSIONS: The activity of the disease in patients with RA is independently associated with higher serum levels of ApoC3.
