32994362 Risk of venous thromboembolism in immune-mediated inflammatory diseases: a UK matched coho 2020 Sep OBJECTIVES: To describe the risk of venous thromboembolism (VTE), and risk factors for VTE, in people with immune-mediated inflammatory diseases (IMID) (ulcerative colitis, Crohn's disease (CD), rheumatoid arthritis (RA) and psoriatic arthritis (PsA)), compared with a matched control population. METHODS: A total of 53 378 people with an IMID were identified over 1999-2019 in the UK Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) primary care database and were matched to 213 512 people without an IMID. The association between the presence of any IMID, and each IMID separately, and risk of VTE was estimated using unadjusted and multivariable-adjusted Cox proportional hazards models. The prevalence of VTE risk factors, and associations between VTE risk factors and risk of VTE, were estimated in people with and without an IMID. RESULTS: People with an IMID were at increased risk of VTE (adjusted HR [aHR] 1.46, 95% CI 1.36,1.56), compared with matched controls. When assessing individual diseases, risk was increased for CD (aHR 1.74, 95% CI 1.45 to 2.08), ulcerative colitis (aHR 1.27, 95% CI 1.10 to 1.45) and RA (aHR 1.54, 95% CI 1.40 to 1.70) but there was no evidence of an association for PsA (aHR 1.21, 95% CI 0.96 to 1.52). In people with an IMID, independent risk factors for VTE included male sex, overweight/obese body mass index, current smoking, history of fracture, and, across study follow-up, abnormal platelet count. CONCLUSIONS: VTE risk is increased in people with IMIDs. Routinely available clinical information may be helpful to identify individuals with an IMID at increased future risk of VTE. OBSERVATIONAL STUDY REGISTRATION NUMBER: Clinicaltrials.gov (NCT03835780).
33383830 A Systematic Review to Identify the Effects of Biologics in the Feet of Patients with Rheu 2020 Dec 29 Background and objective: Ninety percent of patients with rheumatoid arthritis (RA) feel foot pain during the disease process. Pharmacological treatment of RA has a systematic effect on the body and includes: Nonsteroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs (DMARDs) and biologics. The objective of our review was to examine the impact of biologics on patients with RA 'foot. Methods and material: A systematic review of randomized control trials and observational studies that evaluated the efficacy of biologics against other pharmacological treatment, and included a foot outcome measure. The search covered MEDLINE Ovid, Pubmed, CINAHL, Cochrane Library, Evidence Search, and Web of Science. Risk of bias was evaluated using Cochrane guidance and the Newcastle Ottawa Scale adapted version. Results: A total of eight studies fully met the inclusion criteria: Three randomized control trials, and five observational studies were the basis of our review. A total sample of 1856 RA patients with RA treatment participated. The use of biologics was not associated as a risk factor for post-operative surgical site infection or delayed wound healing. The benefits of biologics, in terms of the disease evolution, were assessed using X-ray. Conclusion: Evidence suggests that the use of biologics is not a risk factor for post-operative surgical site infection or delayed wound healing. The use of biologics presents benefits in terms of the disease evolution assessed through X-ray.
32031759 Recent Advances in Nanotheranostics for Treat-to-Target of Rheumatoid Arthritis. 2020 Mar Early diagnosis, standardized treatment, and regular monitoring are the clinical treatment principle of rheumatoid arthritis (RA). The overarching principles and recommendations of treat-to-target (T2T) in RA advocate remission as the optimum aim, especially for patients with very early disease who are initiating therapy with anti-RA medications. However, traditional anti-RA drugs cannot selectively target the inflammatory areas and may cause serious side effects due to its short biological half-life and poor bioavailability. These limitations have significantly driven the research and application of nanomaterial-based drugs in theranostics of RA. Nanomedicines have appropriate sizes and easily modified surfaces which can enhance their biological compatibility and prolong circulation time of drug-loading systems in vivo. Traditional T2T regimens cannot evaluate the efficacy of drugs in real time, while clinical drug nanosizing can realize the integration of diagnosis and treatment of RA. This review bridges clinically proposed T2T concepts and nanomedicine in an integrated system for RA early-stage diagnosis and treatment. The most advanced progress in various nanodrug delivery systems for theranostics of RA is summarized, establishing a clear path and a new perspective for further optimization of T2T. Finally, the key facing challenges are discussed and prospects are addressed.
33035753 Homotherapy for heteropathy active components and mechanisms of Qiang-Huo-Sheng-Shi decoct 2020 Dec Qiang-Huo-Sheng-Shi decoction (QHSSD), a classic traditional Chinese herbal formula, which has been reported to be effective in rheumatoid arthritis (RA) and osteoarthritis (OA). However, the concurrent targeting mechanism of how the aforementioned formula is valid in the two distinct diseases OA and RA, which represents the homotherapy-for-heteropathy principle in traditional Chinese medicine (TCM), have not yet been clarified. In the present study, network pharmacology was adopted to analyze the potential molecular mechanism, and therapeutic effective components of QHSSD on both OA and RA. A total of 153 active ingredients in QHSSD were identified, 142 of which associated with 59 potential targets for the two diseases were identified. By constructing the protein-protein interaction network and the compound-target-disease network, 72 compounds and 10 proteins were obtained as the hub targets of QHSSD against OA and RA. The hub genes of ESR1, PTGS2, PPARG, IL1B, TNF, MMP2, IL6, CYP3A4, MAPK8, and ALB were mainly involved in osteoclast differentiation, the NF-κB and TNF signaling pathways. Moreover, molecular docking results showed that the screened active compounds had a high affinity for the hub genes. This study provides new insight into the molecular mechanisms behind how QHSSD presents homotherapy-for-heteropathy therapeutic efficacy in both OA and RA. For the first time, a two-disease model was linked with a TCM formula using network pharmacology to identify the key active components and understand the common mechanisms of its multi-pathway regulation. This study will inspire more innovative and important studies on the modern research of TCM formulas.
32000736 Impact of radiological honeycombing in rheumatoid arthritis-associated interstitial lung d 2020 Jan 30 BACKGROUND: Interstitial lung disease (ILD) is the most common and important pulmonary manifestation of rheumatoid arthritis (RA). A radiological honeycomb pattern has been described in diverse forms of ILD that can impact survival. However, the clinical course and sequential radiological changes in the formation of the honeycomb pattern in patients with RA-ILD is not fully understood. METHODS: We evaluated the sequential changes in computed tomography findings in 40 patients with chronic forms of RA-ILD without the honeycomb pattern at initial diagnosis. We classified the patients into the Non-honeycomb group and Honeycomb group, and then analyzed the characteristics and prognosis of the two groups. The term "honeycomb formation" indicated a positive finding of honeycombing on any available follow-up CT. RESULTS: Our RA-ILD cohort included patients with probable usual interstitial pneumonia (UIP) (35%), nonspecific interstitial pneumonia (NSIP) (20%), and mixed NSIP/UIP (45%). Among all RA-ILD patients, 16 (40%) showed honeycomb formation on follow-up CT (median time between initial and last follow-up CT was 4.7 years). Patient characteristics and prognosis were not significantly different between the Non-honeycomb and Honeycomb groups. However, Kaplan-Meier survival curve for the time from the date of honeycomb formation to death showed a poor median survival time of 3.2 years. CONCLUSIONS: A certain number of patients with RA-ILD developed a honeycomb pattern during long-term follow-up, regardless of whether they had UIP or NSIP. Prognosis in the patients with characteristics of both progressive ILD and honeycomb formation could be poor. Although radiological findings over the disease course and clinical disease behavior in RA-ILD are heterogenous, clinicians should be alert to the possibility of progressive disease and poor prognosis in patients with RA-ILD who form a honeycomb pattern during follow-up observation.
31829080 Comparative study of HO-1 expressing synovial lining cells between RA and OA. 2021 Jan OBJECTIVES: We aimed to clarify the characteristics of heme oxygenase (HO)-1 expressing cells in the synovium from rheumatoid arthritis (RA) and osteoarthritis (OA), and to investigate the co-expression of HO-1 and IgG-Fc/HLA-DR complex. METHODS: The characteristics of HO-1 expressing cells in the synovium were investigated by using immunohistochemistry. The co-expression of HO-1 and IgG-Fc/HLA-DR complex was examined by an in situ proximity ligation assay (PLA) with immunofluorescence. HO-1 mRNA was investigated by reverse transcription-polymerase chain reaction. RESULTS: The number of HO-1(+) cells from the RA synovium is higher than that from OA synovium. The double positive cells of HO-1 and IgG-Fc/HLA-DR complex were detected by the in situ PLA with immunofluorescence in RA synovium. HO-1 mRNA was detected in both RA and OA synovium. CONCLUSION: A portion of HO-1(+) cells with IgG-Fc/HLA-DR complex in lining layer of RA may be concluded as one of antigen presenting cells in RA and may be involved in production of RF.
30482509 Prognostic Factors for Sustained Remission in a "Real Life" Cohort of Rheumatoid Arthritis 2020 Sep INTRODUCTION: Rheumatoid arthritis (RA) is the most frequent chronic polyarthritis. The current goal of RA treatment is to achieve clinical remission. OBJECTIVE: The goal of this study was to determine the prevalence of remission in a cohort of patients from clinical practice, and to identify potentially modifiable factors associated with remission. METHODS: A retrospective study was performed on a cohort of RA patients seen at the first consultation at the HUGC Rheumatology Service Dr. Negrín (HUGCDN) between first of January 2000 and thirtieth of April 2014. Sustained remission was defined as DAS28 less than 2.6 in the last two available visits in the medical history. RESULTS: A total of 463 patients were consecutively included, most (75%) women, with a mean age at the onset of RA of 50 years and a mean duration of the disease at follow-up of 8 years. 46% of the patients achieved sustained remission. Multiple logistic regression analyses found male sex (P=.031, OR 1.7, 95% CI 1.05-2.82), diagnosis in the first year of symptoms (P=.023, OR 1.7, 95% CI 1.07-2.69) and the initial DAS28 (P=.035) to be independent predictors for sustained remission. CONCLUSIONS: The 46% of the patients with RA followed in the HUGC Dr. Negrín are in persistent remission, being the early diagnosis a modifiable factor predictor of remission. Thus, an objective of the Rheumatology Service should be to improve the diagnostic delay of RA in the health area.
31779487 Unmet needs in the management of cardiovascular risk in inflammatory joint diseases. 2020 Jan Introduction: Increased cardiovascular (CV) morbidity and mortality is observed in inflammatory joint diseases (IJDs) such as rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. However, the management of CV disease in these conditions is far from being well established.Areas covered: This review summarizes the main epidemiologic, pathophysiological, and clinical risk factors of CV disease associated with IJDs. Less common aspects on early diagnosis and risk stratification of the CV disease in these conditions are also discussed. In Europe, the most commonly used risk algorithm in patients with IJDs is the modified SCORE index based on the revised recommendations proposed by the EULAR task force in 2017.Expert opinion: Early identification of IJD patients at high risk of CV disease is essential. It should include the use of complementary noninvasive imaging techniques. A multidisciplinary approach aimed to improve heart-healthy habits, including strict control of classic CV risk factors is crucial. Adequate management of the underlying IJD is also of main importance since the reduction of disease activity decreases the risk of CV events. Non-steroidal anti-inflammatory drugs may have a lesser harmful effect in IJD than in the general population, due to their anti-inflammatory effects along with other potential beneficial effects.
32023600 [CD20-negative diffuse large B-cell lymphoma complicated by rheumatoid arthritis]. 2020 CD20 antigen is an important marker for diagnosis of B-cell neoplasms that is highly expressed on the surface of neoplastic B lymphocytes. Patients with rheumatoid arthritis (RA) have an increased risk of developing malignant lymphoma, of which diffuse large B-cell lymphoma (DLBCL) is the most common type. We report an unusual case of CD20-negative DLBCL complicated by rheumatoid arthritis. An 81-year old female presented with a left-sided cervical tumor, enlarged tonsil, and polyarticular pain. Pathological findings of the left tonsil showed proliferation of large atypical cells with irregular shaped nuclei. Most large cells were negative for CD3 and CD20. Additionally, these cells were positive for CD79a, BCL2, and MUM1, and negative for CD10, CD138, BCL6, PAX5, EBV-ISH, HHV8, and ALK.. Therefore, she was diagnosed with CD20-negative DLBCL complicated with RA and received dose-modified CHOP that achieved partial remission. Because CD20-negative DLBCL is rare, the identification of the clinicopathological features of this disease is urgently required.
31848023 Factors associated with long-term persistence of rituximab in rheumatoid arthritis In clin 2020 Jul 10 BACKGROUND AND OBJECTIVE: Treatment of rheumatoid arthritis with rituximab (RTX) requires repeated cycles, but there is no well-established retreatment regimen in dose and frequency. The objective was to analyse the persistence of RTX treatment and factors that influence in terms of routine clinical practice. METHODS: Rituximab in Rheumatoid Arthritis (RITAR Study) is an observational, retrospective study that analyses the persistence of RTX in a cohort from 2003 to 2015. Persistence was calculated by the Kaplan-Meier analysis; curves were compared with the Log-Rank test. Cox regression was used to quantify the risk of discontinuation and multivariate analyses were conducted to determine the factors associated with the persistence of the treatment. RESULTS: 454 cycles of RTX in 114 patients were included. Median survival was 10.0 years and incidence rate of discontinuation was 7.7 per 100 patients/year. Factors associated with persistence were autoantibody positivity and use of RTX in combination with csDMARDs. Sex, age, number of comorbidities, rheumatoid arthritis evolution, number of complications, basal DAS28, basal HAQ, number of lines of treatment, fixed or on demand retreatment and year of RTX starting were not associated. Multivariable models confirmed the relationship between autoantibody positivity, monotherapy and persistence of RTX. CONCLUSIONS: The persistence of RTX in clinical practice is higher in seropositive patients and in those who are treated with RTX associated with a csDMARD. Dose per cycle and retreatment frequency do not have a decisive role in rituximab persistence.
33379844 [Clinical characteristics of elderly and younger onset rheumatoid arthritis]. 2020 Dec 22 Objective: To compare the clinical and laboratory characteristics and therapy methods of elderly onset rheumatoid arthritis (EORA) and younger onset rheumatoid arthritis (YORA). Methods: The clinical, laboratory and therapeutic data of 481 RA patients in the Department of Rheumatology and Immunology in Peking University Third Hospital from January 2013 to December 2018 were collected and used to analyze the difference of characteristics between EORA group and YORA group, which might be useful for better diagnosis and treatment of EORA patients. Quantitative data of normal distribution were compared with t test between the two groups. Results: There were 481 patients in this cohort, of which 137(28.5%) were EORA, 344(71.5%) were YORA, with a mean age of (59±14) years (19-87 years). There were 358 females (74.4%) and 123 males (25.6%). The percentage of male patients was obviously higher in EORA group (36.5% vs 21.2%, χ(2)=12.012, P<0.01), and the average disease course was obviously shorter (Z=-7.985, P<0.01). Disease Activity Score 28 (DAS28) score was higher in EORA group (5.6±1.3 vs 5.2±1.6, t=2.549, P<0.05), meanwhile the incidences of pleural effusion and interstitial lung disease (ILD) were higher (6.6% vs 1.7%, 29.9% vs 18.3%, respectively; χ(2)=7.550, 7.797, both P<0.05). The incidences of venous thrombosis, primary hypertension, diabetes mellitus, cerebrovascular disease, coronary heart disease (CHD), peripheral atherosclerosis and cataract in EORA group were all significantly higher than those in YORA group (all P<0.05). Erythrocyte sedimentation rate (ESR) and D-Dimer in EORA group were all remarkably higher (both P<0.05). The rate of using glucocorticoid in EORA group was higher but the rate of using methotrexate and anti-tumor necrosis factor-α agents were lower (χ(2)=5.271, 8.407, 9.356, all P<0.05). Conclusion: Compared to YORA group, the percentage of male patients and disease activity of EORA group are higher. The occurrence of pleural effusion, ILD, venous thrombosis, primary hypertension, diabetes mellitus, cerebrovascular disease, CHD, peripheral atherosclerosis and cataract in EORA group are higher than those in YORA group.
32293530 Differential regulation and correlation between galectin-9 and anti-CCP antibody (ACPA) in 2020 Apr 15 BACKGROUND: Galectin-9 (Gal-9) is involved in the regulatory process of immune responses or inflammation. The aim of the present study is to characterize circulating Gal-9 in patients with rheumatoid arthritis (RA) and its relationship with RA disease activity and phenotype. METHODS: A total of 116 RA patients and 31 age-matched healthy controls were included in this study. Disease activity of RA patients was determined by Disease Activity Score of 28 joint scoring system (DAS28-ESR). Levels of Gal-9 in serum were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: Serum levels of Gal-9 were significantly higher in patients with RA compared to those in controls (median 7577 pg/ml [interquartile range (IQR) 5570-10,201] versus 4738 pg/ml [IQR 4267-5630], p = 0.001). There were significant differences in serum Gal-9 between RA patients with and without RA-ILD (9606 pg/ml [IQR 8522-12,167] versus 7078 pg/ml [IQR 5225-9447], p < 0.001) or those with and without advanced joint damage (stage II-IV, 9606 pg/ml [IQR 8522-12,167] versus 7078 pg/ml [IQR 5225-9447], p < 0.001). Although serum levels of Gal-9 correlated with the titers of ACPA (r = 0.275, p = 0.002), levels of ACPA titers conferred the different relationship, between serum Gal-9 and inflammatory mediators or RA disease activity. Although Gal-9 was correlated with ACPA titers (r = 0.508, p = 0.002), there was no correlation between Gal-9 levels and erythrocyte sedimentation rate (ESR), matrix metalloproteinase-3 (MMP-3), or DAS28-ESR in RA patients with high titers of ACPA (> 200 U/ml). Conversely, Gal-9 was correlated with MMP-3 (r = 0.300, p = 0.007) or DAS28-ESR (r = 0.331, p = 0.004) but not with ACPA titer in RA patients with low titers of ACPA titers (< 200 U/ml). CONCLUSIONS: Serum levels of Gal-9 were increased in RA patients and associated with RA disease activity in RA patients without high titers of ACPA. The levels of ACPA titers may influence the values of circulating Gal-9 in RA patients with various clinical phenotypes. These data suggest that Gal-9 possessed the properties of pro-inflammatory or arthropathic biomarker under the status of ACPA titers.
31269834 Possible role of β-galactosidase in rheumatoid arthritis. 2020 Jul Objective: To investigate the potential role of β-galactosidase in altering immunoglobulin G (IgG) galactosylation in serum of rheumatoid arthritis (RA).Methods: The expression level and activity of β-galactosidase in serum and CD 19(+) B cells were measured by enzyme-linked immune sorbent assay (ELISA). The effect of β-galactosidase on the N-glycan changes in serum from mice intravenously treated with β-galactosidase was observed by linear ion-trap quadrupole-electrospray ionization mass spectrometry (LTQ-ESI-MS). We established a collagen-induced arthritis (CIA) rat model to explore the biological function of β-galactosidase in RA.Results: The expression level of β-galactosidase in serum of 32 patients was elevated when compared with those of 30 healthy controls. The activity and expression level of β-galactosidase in CD19(+) B cells from RA patients was higher than those from healthy controls. The ratio of m/z 1142/937 was reduced in mice treated with β-galactosidase when compared with normal mice. We found that β-galactosidase was implicated in the development of inflammation by affecting body weight and elevating the expression level of interleukin-6, tumor necrosis factor-α, and rheumatoid factor in the serum.Conclusions: Our results suggested the high level of β-galactosidase in B cells and serum of RA patients and revealed that altered β-galactosidase may be implicated in the progression of inflammation.
33264361 Mortality in rheumatoid arthritis patients with pulmonary nontuberculous mycobacterial dis 2020 OBJECTIVE: The aim of this study was to compare long-term mortality following diagnosis of pulmonary nontuberculous mycobacterial (NTM) disease between patients with and without rheumatoid arthritis (RA) and to evaluate predictive factors for death outcomes. METHODS: We reviewed the electronic medical records of all patients who were newly diagnosed with pulmonary NTM disease at participating institutions between August 2009 and December 2018. Patients were followed until death, loss to follow-up, or the end of the study. Taking into consideration the presence of competing risks, we used the cumulative incidence function with Gray's test and Fine-Gray regression analysis for survival analysis. RESULTS: A total of 225 patients (34 RA patients and 191 non-RA controls) were followed, with a mean time of 47.5 months. Death occurred in 35.3% of RA patients and 25.7% of non-RA patients. An exacerbation of pulmonary NTM disease represented the major cause of death. The estimated cumulative incidence of all-cause death at 5 years was 24% for RA patients and 23% for non-RA patients. For NTM-related death, the 5-year cumulative incidence rate was estimated to be 11% for RA patients and 18% for non-RA patients. Gray's test revealed that long-term mortality estimates were not significantly different between patient groups. Fine-Gray regression analysis showed that the predictive factors for NTM-related death were advanced age (adjusted hazards ratio 7.28 [95% confidence interval 2.91-18.20] for ≥80 years and 3.68 [1.46-9.26] for 70-80 years vs. <70 years), male sex (2.40 [1.29-4.45]), Mycobacterium abscessus complex (4.30 [1.46-12.69] vs. M. avium), and cavitary disease (4.08 [1.70-9.80]). CONCLUSIONS: RA patients with pulmonary NTM disease were not at greater risk of long-term mortality compared with non-RA patients. Rather, advanced age, male sex, causative NTM species, and cavitary NTM disease should be considered when predicting the outcomes of RA patients with pulmonary NTM disease.
32651684 Apoptosis and secondary necrosis of neutrophils and monocytes in the immunopathogenesis of 2020 Sep Rheumatoid arthritis (RA) is a progressive chronic inflammatory and autoimmune joint disease. Neutrophils and monocytes are the main target cells of innate immune defense that modulate the course of inflammatory rheumatic diseases. Dysfunctional phagocytosis is a common feature in RA. The aim of this study was to evaluate the diagnostic value of apoptotic changes in neutrophils and monocytes and their relationship with rheumatoid activity measured by the DAS28 score. We used the APOLECT flow cytometric assay for evaluating primary necrotic, apoptotic, and secondary necrotic neutrophils and monocytes determination in RA patients compared with healthy controls. The apoptotic granulocytes were greater in RA patients compared to healthy controls (0.76 ± 0.15% vs. 0.58 ± 0.17%, P < 0.05). The percentage of primary necrotic granulocytes was significantly elevated in RA patients compared to healthy controls (3.84 ± 0.5% vs. 1.96 ± 0.33%). No significant difference was noted for primary necrotic monocytes. The number of secondary necrotic granulocytes and monocytes was high in RA patients (0.94 ± 0.15% vs. 0.4 ± 0.06% and 4.83 ± 1.06% vs. 1.8 ± 0.33%, respectively). The obtained results suggest that neutrophils and monocytes undergo apoptotic modifications which are accompanied by secondary necrotic cells formation in RA. These shifts may lead to autoantigen accumulation that results in the progressive course RA.
32819925 Patients' experiences regarding self-monitoring of the disease course: an observational pi 2020 Aug 20 OBJECTIVES: Self-monitoring the disease course is a relatively new concept in the management of patients with inflammatory rheumatic diseases (IRDs). The aims of this pilot study were to obtain patients' experiences with online self-monitoring, to assess information about the agreement between the disease course assessed with patient-reported outcome measures (PROMs) and an objectively measured Disease Activity Score 28 (DAS28) by the rheumatologist, and to assess adherence to predetermined PROM frequency intervals. DESIGN: Observational study using qualitative and quantitative methods. SETTING: The rheumatology outpatient clinic of a teaching hospital in The Netherlands (secondary care). PARTICIPANTS: 47 patients with an IRD who regularly attended the outpatient clinic. METHODS: Patients completed PROMs by using an online self-monitoring program. Their experiences regarding self-monitoring were qualitatively assessed through a focus group discussion and telephone interviews using a thematic analysis approach. Adherence to the predefined PROM frequency (completed PROM assessments within the predetermined frequency) and the agreement between the DAS28 course and PROM values (Rheumatoid Arthritis Disease Activity Index-5 and the Rheumatoid Arthritis Impact of Disease (RAID)) were quantitatively assessed using descriptives. RESULTS: Forty-seven patients participated, most of them diagnosed with rheumatoid arthritis (n=38, 80.9%). Three themes were identified: knowledge about and insight into the disease (activity), patient-professional interaction and functionality of the program. Mean adherence to the predetermined PROM frequency was 68.1%. The RAID showed the best agreement with the DAS28 course. Mean participation time was 350 days. CONCLUSION: Patients were predominantly positive about online self-monitoring. They indicated that they gained more knowledge about their disease, felt less dependent on the healthcare professional and valued the insight into their long-term disease course. Barriers were mostly related to technical factors. Patients were able to and willing to self-monitor their disease, which could contribute to a more efficient allocation of outpatient consultations in the future.
31504979 Elevated free secretory component in early rheumatoid arthritis and prior to arthritis dev 2020 May 1 OBJECTIVES: Considering growing evidence of mucosal involvement in RA induction, this study investigated circulating free secretory component (SC) in patients with either recent-onset RA or with ACPA and musculoskeletal pain. METHODS: Two prospective cohorts were studied: TIRA-2 comprising 452 recent-onset RA patients with 3 years of clinical and radiological follow-up, and TIRx patients (n = 104) with ACPA IgG and musculoskeletal pain followed for 290 weeks (median). Blood donors and three different chronic inflammatory diseases served as controls. Free SC was analysed by sandwich ELISA. RESULTS: Serum levels of free SC were significantly higher in TIRA-2 patients compared with TIRx and all control groups (P < 0.01). Among TIRx patients who subsequently developed arthritis, free SC levels were higher compared with all control groups (P < 0.05) except ankylosing spondylitis (P = 0.74). In TIRA-2, patients with ACPA had higher baseline levels of free SC compared with ACPA negative patients (P < 0.001). Free SC status at baseline did not predict radiographic joint damage or disease activity over time. In TIRx, elevated free SC at baseline trendwise associated with arthritis development during follow-up (P = 0.066) but this disappeared when adjusting for confounders (P = 0.72). Cigarette smoking was associated with higher levels of free SC in both cohorts. CONCLUSION: Serum free SC levels are increased in recent-onset RA compared with other inflammatory diseases, and associate with ACPA and smoking. Free SC is elevated before arthritis development among ACPA positive patients with musculoskeletal pain, but does not predict arthritis development. These findings support mucosal engagement in RA development.
32896261 Three-year clinical outcomes in patients with rheumatoid arthritis treated with certolizum 2021 Jul OBJECTIVES: To describe the long-term effectiveness and safety of certolizumab pegol in patients with moderate-to-severe rheumatoid arthritis (RA) in a real-world setting in France. METHODS: ECLAIR was a 3-year longitudinal, prospective, observational, multicentre study. The primary objective was to describe the EULAR response after 1 year of certolizumab pegol treatment. Other endpoints included DAS28, clinical disease activity index, health assessment questionnaire disability index, fatigue assessment scale, patient's assessment of arthritis pain, patient and physician global assessments of disease activity, patient quality of life, and long-term safety. RESULTS: A total of 792 patients were enrolled, of whom 776 comprised the safety set, and 733 the full analysis set. In the full analysis set, 559, 469 and 430 patients had a 12-, 24- and 36-month visit, respectively. This included 378, 296 and 246 patients still receiving certolizumab pegol at these visits. The percentage of EULAR responders was 75.3% (305/405 patients with an available EULAR response) at 12, 76.5% (261/341) at 24, and 79.6% (226/284) at 36 months. Among those still receiving certolizumab pegol, the percentage of EULAR responders was 81.7% (237/290) at 12, 81.1% (185/228) at 24, and 87.3% (158/181) at 36 months. Sustained improvements were observed in other effectiveness outcomes. Overall, 45.1% (350/776) of patients experienced 776 adverse drug reactions. No new safety signals were identified. CONCLUSIONS: This is the first prospective, observational study of an anti-TNF treatment in France. The results confirm the effectiveness and safety profile of certolizumab pegol treatment in patients with RA in a real-world setting.
32801270 Two-year Outcomes of Infliximab Discontinuation in Patients with Rheumatoid Arthritis: A R 2020 Objective To investigate the clinical outcomes of rheumatoid arthritis (RA) patients who discontinued infliximab (IFX) treatment at our hospital. Methods Among 249 patients receiving IFX from 2007 to 2015, we retrospectively investigated the clinical courses of 18 who discontinued IFX after achieving the 28-joint disease activity score based on the erythrocyte sedimentation (DAS28-ESR) clinical remission (CR) and whose clinical courses were available continuously for 96 weeks after discontinuation. Results At IFX introduction, the median age was 56.9 (range 36.1-72.4) years, and the disease duration was 5.2 (0.4-25.6) years. The median duration of maintaining either CR or a low disease activity (LDA) with IFX was 37.2 (4.0-91.4) months, and the total duration of IFX therapy was 45.8 (17.1-96.9) months. After discontinuation, 8 patients (44.4%) maintained CR/LDA for 96 weeks (no-flare group), and 10 (55.6%) experienced flares (DAS28-ESR≥3.2) within 96 weeks (flare group). In the no-flare group, six patients receiving intensified conventional synthetic disease-modifying antirheumatic drug (csDMARD) therapy to prevent flare ups simultaneously either with or immediately after discontinuing IFX. In the flare group, four patients received intensified csDMARD therapy. Six patients restarted biological DMARDs (bDMARDs), and all achieved CR again. Ultimately, 12 patients (66.7%) maintained a Bio-free disease control for 96 weeks. A comparison of the clinical backgrounds between the flare and no-flare groups showed no marked difference in their disease duration, IFX dosage, duration of maintaining CR with IFX, or concomitant csDMARDs use. Conclusion Irrespective of the RA disease duration, more than half of all patients maintained a Bio-free condition for 96 weeks. Continuing LDA with IFX for a sufficiently long period of time before discontinuation and preventive intensification of csDMARD therapy may help maintain a Bio-free condition.
33327502 The Lipid Paradox as a Metabolic Checkpoint and Its Therapeutic Significance in Ameliorati 2020 Dec 14 While the most common manifestations associated with rheumatoid arthritis (RA) are synovial damage and inflammation, the systemic effects of this autoimmune disorder are life-threatening, and are prevalent in 0.5-1% of the population, mainly associated with cardiovascular disorders (CVDs). Such effects have been instigated by an altered lipid profile in RA patients, which has been reported to correlate with CV risks. Altered lipid paradox is related to inflammatory burden in RA patients. The review highlights general lipid pathways (exogenous and endogenous), along with the changes in different forms of lipids and lipoproteins in RA conditions, which further contribute to elevated risks of CVDs like ischemic heart disease, atherosclerosis, myocardial infarction etc. The authors provide a deep insight on altered levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TGs) in RA patients and their consequence on the cardiovascular health of the patient. This is followed by a detailed description of the impact of anti-rheumatoid therapy on the lipid profile in RA patients, comprising DMARDs, corticosteroids, anti-TNF agents, anti-IL-6 agents, JAK inhibitors and statins. Furthermore, this review elaborates on the prospects to be considered to optimize future investigation on management of RA and treatment therapies targeting altered lipid paradigms in patients.
