30057321 Prophylactic effect of sulfasalazine against Pneumocystis pneumonia in patients with rheum 2019 Feb OBJECTIVES: To evaluate the prophylactic effect of sulfasalazine against Pneumocystis jirovecii pneumonia (PJP) among rheumatoid arthritis (RA) patients. METHODS: We used a nationwide Japanese multicenter RA database to extract data from 2005 and 2014. To identify PJP cases, we selected patients hospitalized for PJP and verified their diagnosis. Two control groups, one unmatched and the other matched for age, sex, glucocorticoid, methotrexate, and tacrolimus dosage, and the use (and type, if used) of biological disease-modifying antirheumatic drug were selected by incidence-density sampling. The odds ratios for PJP associated with sulfasalazine use and other clinical factors were estimated by exact and standard conditional logistic regression. RESULTS: From 18,668 participants, 60 cases, 356 unmatched controls, and 337 matched controls were selected. None of the cases received sulfasalazine before PJP onset. A comparison of the cases with the unmatched controls showed that sulfasalazine use carried a decreased risk of PJP (adjusted odds ratio 0.18, 95% confidence interval 0.00-0.92). A comparison of the cases and matched controls also showed that sulfasalazine use had a decreased risk of PJP (0.08, 0.00-0.36). In an analysis of the cases and unmatched controls who did not receive sulfasalazine, an increased risk of PJP was associated with lung disease (3.88, 1.89-7.95) and the use of glucocorticoid (5.71, 2.68-12.19), methotrexate (5.25, 2.01-13.74), and tumor necrosis factor inhibitors (2.32, 1.10-4.93). CONCLUSIONS: The results of this nested case-control study demonstrated the preventive effect of sulfasalazine against PJP. The results await confirmation by future prospective studies.
31100034 Computational deconvolution of synovial tissue cellular composition: presence of adipocyte 2019 Jun 1 Osteoarthritis (OA) and rheumatoid arthritis (RA) are the most common forms of arthritis. The synovial tissue is the major site of inflammation of OA and RA and consists of diverse cells. Synovial tissue cell composition changes during arthritis pathogenesis and progression have not been systematically characterized and may provide critical insights into disease processes. In this study we aimed at systematically examining cellular changes in synovial tissue. Publicly available synovial tissue transcriptomic data sets were used. We computationally estimated cell compositions in synovial tissue based on transcriptomic data and compared cell compositions in different diseases or at different disease stages. Synovial fibroblasts, macrophages, adipocytes, and immune cells were the major cell types in all synovial tissue. Both OA and RA patients had a significantly lower adipocyte fraction compared with healthy controls. The decrease trend was also observed during OA and RA progression. The fraction of monocytes was also increased in both OA and RA arthritis patients, consistent with the observations that inflammation involved in both OA and RA. But the monocyte fraction in RAs was much higher than the ones in healthy controls and OAs. The M2 macrophage fraction was reduced in RA compared with OA, the reduction trend continued during RA progression from the early- to the late-stage. There were consistent cell composition differences between different types or stages of arthritis. Both in RA and OA, the new discovery of changes in the adipocyte and M2 macrophage fractions has potential leading to novel therapeutic development.
31813863 Effectiveness of methotrexate in combination therapy in a rat collagen-induced arthritis m 2019 Sep This study was to investigate the effect of methotrexate in combination therapy by the characteristic cytokine in Th17 cells and the frequency of Tregs, which involved in the induction and pathological progress of rheumatoid arthritis (RA). The collagen-induced arthritis rats were treated with methotrexate + prednisone, methotrexate + disease-modifying rheumatic drugs (DMARDs) and methotrexate + TNFi, respectively. The following parameters were observed to evaluate three treatments: the frequency and function of Th17 cells and Tregs, the scores of X-rays, H&E staining and immunohistochemistry. For rats starting methotrexate + prednisone (low doses), the frequency and suppressive function of Th17 cells decreased while the frequency of Tregs increased, which were the same in methotrexate + TNFi. Immunohistochemical in the pathological sections of ankle joint showed the same results. The effect of methotrexate + DMARDs treatment was slightly inferior to the other combination therapies. In summary, rats treated with methotrexate + prednisone can achieve high level of Tregs and low level of Th17 cells and IL-17. Low doses of glucocorticoid suggesting a critical role in the pathogenesis of rheumatoid arthritis may have the similar effect as DMARDs.
30611755 High levels of antibodies to citrullinated α-enolase peptide-1 (CEP-1) identify erosions 2019 Mar We evaluated the clinical performance of anti-CEP-1 in a Chinese rheumatoid arthritis (RA) cohort. A total of 264 subjects were tested, including 101 RA patients, 38 juvenile idiopathic arthritis (JIA) patients, 46 disease control (DC) and 79 healthy controls (HC). The presence of anti-CEP-1 in patients with RA, JIA, DCs and HC were 61.4%, 13.2%, 15.2% and 5.1%, respectively. Anti-CCP2 demonstrated the highest positive likelihood ratio of 10.11 in the diagnosis of RA, followed by RF (8.88) and anti-CEP-1 (5.82). Anti-CEP-1 positive RA patients displayed significantly higher DAS28 compared to anti-CEP-1 negative RA patients (p = .045). Significant associations were identified between anti-CEP-1 and joint erosions at anti-CEP-1 value of >124.78 U/ml (p = .0026) and between anti-CEP-1 and ILD at anti-CEP-1 value of >185.91 U/ml (p = .0222). Our findings indicate that anti-CEP-1 may not be able to replace anti-CCP2 for routine diagnosis for RA, but they may be helpful for subtyping of the disease.
31820135 A quality improvement intervention failed to significantly increase pneumococcal and influ 2020 Mar OBJECTIVES: Pneumococcal and influenza vaccination rates have been suboptimal in studies of immunosuppressed patients. We aimed to assess barriers to and increase rates of 23-valent pneumococcal polysaccharide vaccine (PPSV23) and influenza vaccination in this group. The primary endpoint was a statistically significant increase in adequate PPSV23 and influenza vaccination. METHODS: In 2017, rheumatology outpatients completed an anonymous questionnaire recording vaccination knowledge, status, and barriers. Simultaneously, a low-cost multifaceted quality improvement (QI) intervention was performed. All outpatients on oral steroids, immunosuppressant conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or biologics disease-modifying antirheumatic drugs (bDMARDs) were included in the study. In 2018, post-intervention, the clinic was re-assessed. Demographics, diagnosis, medications, smart phone access, and willingness to use this for vaccination reminders were assessed for independent vaccination predictors using binary logistic regression analysis. RESULTS: Four hundred twenty-five patients were included (72.6% rheumatoid arthritis, 74% women, 45.6% ≥ 60 years old). From 2017 to 2018, PPSV23 vaccination rates changed from 41.0 to 47.2% (P = 0.29) and influenza from 61.8 to 62.1% (P = 0.95). The most common reason for non-vaccination was lack of awareness. Following the intervention, this changed for influenza (36.7 to 34.2%) and PPSV23 (82.1 to 76.4%). General practitioners performed most vaccinations, only 3.6% were delivered in the hospital. Significant predictors of PPSV23 vaccination were older age {≥ 80 years had an OR 41.66 (95% CI 3.69-469.8, P = 0.003), compared with ≤ 39 years}, bDMARD use (OR 2.80, 95% CI 1.24-6.32, P = 0.013), and adequate influenza vaccination (OR 9.01, 95% CI 4.40-18.42, P < 0.001). Up-to-date PPSV23 vaccination (OR 8.93, 95% CI 4.39-18.17, P < 0.001) predicted influenza vaccination. CONCLUSIONS: PPSV23 and influenza vaccination rates were suboptimal. The intervention did not cause a statistically significant change in vaccination rates. Point-of-care vaccination may be more effective.Key Points• Low vaccination rates amongst immunosuppressed inflammatory arthritis outpatients• Less than 5% of vaccinations occurred in hospital• There was no statistically significant difference in the rates of adequate PPSV23 (41.0 to 47.2%) or influenza (61.8 to 62.1%) vaccination following our intervention.
31093950 Peficitinib: First Global Approval. 2019 Jun Peficitinib [Smyraf(®) (Astellas Pharma)] is a Janus kinase (JAK)1, JAK2, JAK3 and tyrosine kinase (Tyk)2 (pan-JAK) inhibitor recently approved in Japan for the treatment of rheumatoid arthritis. Inhibition of JAK suppresses the activation of cytokine signalling pathways involved in inflammation and joint destruction in rheumatoid arthritis. Peficitinib has been shown to significantly improve ACR20 and other measures of disease severity and to reduce the mean modified total Sharp score change from baseline in clinical trials. This article summarizes the milestones in the development of peficitinib leading to this first approval as a treatment for rheumatoid arthritis in patients who have an inadequate response to conventional therapies.
31297603 [Long-term trends in rheumatology care : Achievements and deficits in 25 years of the Ger 2019 Oct BACKGROUND: Since 1993, data on the care and quality of life of patients with inflammatory rheumatic diseases have been collected in the German National Database (NDB) of the regional collaborative rheumatology centers. OBJECTIVE: In this review long-term trends on treatment, disease activity and gainful employment of the most common inflammatory rheumatic diseases are presented and the most important analyses from 25 years of the NDB are summarized. METHODS: Between 15 and 17 rheumatological institutions take part in the core documentation and once a year collect data from a total of more than 10,000 patients. The rheumatologists document the disease status and care, the patients report on their state of health and the effects of the disease. RESULTS: The biologics era at the beginning of the twenty-first century has led to changes in the therapeutic spectrum of most inflammatory rheumatic diseases, especially in rheumatoid arthritis and ankylosing spondylitis. Some basic therapies formerly used are hardly used anymore and glucocorticoids are used less frequently. Methotrexate has remained the standard therapy for rheumatoid arthritis over the years. Nowadays, nearly 30% of patients with rheumatoid arthritis receive treatment with biologics. Disease activity, functional and social restrictions have decreased across all diseases. CONCLUSION: The improved health status of many patients with rheumatic diseases confirms the high level of care provided by the rheumatism centers involved in the NDB. The increasing specification of measuring instruments and the standardization of documentation systems are major challenges that the NDB will have to face in the coming years if it is to remain in the digital age.
30770511 Advancing Stiffness Measurement in Rheumatic Disease: Report from the Stiffness Special In 2019 Oct OBJECTIVE: To improve measurement of stiffness in rheumatic disease. METHODS: Data presented included (1) 2 qualitative projects, (2) the rheumatoid arthritis (RA) stiffness patient-reported outcome measure (RAST), and (3) 3 items assessing stiffness severity, duration, and interference. RESULTS: Stiffness is multidimensional and includes aspects of stiffness experience such as duration, severity, and effect. Stiffness items showed construct validity in RA. Further efforts are required to develop an instrument that will be taken through the Outcome Measures in Rheumatology (OMERACT) Filter 2.1 for instrument selection. CONCLUSION: The research agenda for the group includes domain content voting for individual diseases, and development of stiffness item banks and disease-specific short forms.
31523041 Reliability of Magnetic Resonance Imaging (MRI) Scoring of the Metatarsophalangeal Joints 2020 Aug 1 OBJECTIVE: The Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) is validated for hand MRI. Its reliability applied to metatarsophalangeal (MTP 1-5) joints is unknown and was studied in early arthritis and clinically suspect arthralgia. METHODS: Patients underwent 1.5 Tesla MRI of MTP, metacarpophalangeal (MCP 2-5), and wrist joints. Two paired readers scored bone marrow edema (BME), synovitis, tenosynovitis, and erosions. Interreader reliability was assessed of 441 consecutive early arthritis patients at baseline, 215 by 2 readers, and the remaining 226 by 2 different readers. Two readers scored baseline MRI of 82 consecutive patients with clinically suspect arthralgia, and 40 randomly selected patients by 9 readers. Intrareader reliability was determined on a random set of 15 early arthritis patients, scored twice by 2 readers. For change scores, 30 early arthritis patients with baseline and 1-year followup MRI were scored by 2 readers. Intraclass correlation coefficients (ICC), Bland-Altman (BA) plots, and smallest detectable change (SDC) were determined. MRI data of MTP joints were compared to wrist and MCP joints. RESULTS: Interreader ICC and mean scores in early arthritis were BME ICC 0.91-0.92 (mean 1.5 ± SD 2.6), synovitis 0.90-0.92 (1.3 ± 1.7), tenosynovitis 0.80-0.85 (1.1 ± 1.8), and erosions 0.88-0.89 (0.7 ± 1.0). In patients with clinically suspect arthralgia, ICC were comparable. Intrareader ICC for inflammatory MRI features were 0.84-0.98, for erosions 0.71 (reader 1), and 0.92 (reader 2). Change score ICC were ≥ 0.90, except erosions (0.77). SDC were ≤ 1.0. BA plots showed no systematic bias. Reliability scores of MTP joints were similar to MCP and wrist joints. CONCLUSION: Status and change MRI scores of BME, synovitis, tenosynovitis, and erosions of MTP joints can be assessed reliably by RAMRIS.
31782014 Symptomatic elevation creatine kinase following treatment of rheumatoid arthritis with bar 2020 Feb The aim of RA treatment is to achieve reduction of disease activity and prevent joint damage and disability. Baricitinib is a synthetic small molecule which targets the JAK/STAT pathway which is implicated in the inflammatory response in RA. Baricitinib selectively targets JAK1 and JAK2 and has been shown to have efficacy in treating patients with RA. Common adverse effects reported during baricitinib therapy includes infection, asymptomatic changes in laboratory parameters including changes in neutrophil, lymphocyte, platelet counts, alanine aminotransferase, cholesterol, creatinine and creatine kinase (CK). We report the first two documented cases in Australia of baricitinib-induced symptomatic elevation of CK.
31893595 Atypical Presentation of Choroidal Folds: Steroid-induced Central Serous Chorioretinopathy 2019 Dec 31 This article reports a case of choroidal folds and central serous chorioretinopathy-like maculopathy induced by corticosteroid treatment. The patient was a 70-year-old woman who presented with decreased visual acuity in the right eye. She had a history of rheumatoid arthritis and was prescribed 20 mg leflunomide and 16 mg corticosteroid daily. Fundoscopy indicated bilateral macular edema and the presence of choroidal folds. Retinal imaging supported choroidal folds and central serous chorioretinopathy-like maculopathy. Corticosteroid therapy was discontinued, and the patient was followed up. Complete regression of the maculopathy was observed at 8-month follow-up examination.
31393189 Investigation of the predictors of the response to Iguratimod therapy: A post-hoc analysis 2020 Jul Objectives: The treatment response according to patient disease activity during Iguratimod therapy for rheumatoid arthritis has not been sufficiently assessed. A post-hoc analysis of post-marketing surveillance was performed. The treatment effect was evaluated using the European League against Rheumatism (EULAR) response criteria.Methods: Disease Activity Score (DAS) 28 was assessed at various time points. Patients showing a moderate or good response according to the EULAR response criteria at 24 weeks after the start of Iguratimod therapy were considered Responders. Propensity score matching was also performed, after which the factors with the greatest effect on the treatment evaluation were investigated.Results: The mean DAS28 at the start of administration and after 24 weeks was 4.31 and 2.52, respectively, in the Responder and 3.48 and 3.48, respectively, in the Non-responder. After propensity score matching for patient characteristics, the primary factors found to be related to being a Responder were concomitant use of methotrexate (MTX) with Iguratimod, and prior treatment with MTX before the start of Iguratimod.Conclusion: As factors related to the treatment effect, the concomitant use of MTX may contribute to achieving a better effect, and this study has shown that real-world are consistent with the results of clinical trials.
31311386 Addition or removal of concomitant methotrexate alters adalimumab effectiveness in rheumat 2019 Sep Objective: Randomized trials have shown that concomitant methotrexate (MTX) augments the effectiveness of tumour necrosis factor (TNF) inhibitors in rheumatoid arthritis (RA), but its benefit in psoriatic arthritis (PsA) has not been demonstrated. The goal of this study was to examine whether the impact of concomitant MTX on therapeutic outcomes in patients with PsA was similar to its effects in RA. Methods: We used data from highly comparable and concurrent observational studies of patients with PsA (N = 1424) or RA (N = 3148) who initiated adalimumab therapy during routine clinical care. The 28-joint Disease Activity Score (DAS28) and patient-reported pain scores were evaluated in patients who received 24 months of continuous treatment with adalimumab monotherapy or adalimumab + MTX and in patients who initiated or stopped concomitant MTX during ongoing adalimumab therapy. Results: Twenty-four months of continuous treatment with adalimumab + MTX was superior to adalimumab monotherapy in RA patients, while no significant difference was observed in patients with PsA. RA patients who added MTX during the study showed significant individual improvements in DAS28 and pain scores at 6 months after the change in therapy, while those who removed MTX had slight increases in disease activity. In contrast, in patients with PsA, neither initiation nor removal of MTX during continuous adalimumab therapy had a significant effect on therapeutic outcomes. Conclusion: Addition of MTX to adalimumab confers further therapeutic benefit in patients with RA, but not in those with PsA, suggesting differences in MTX effects in these two patient populations. Clinicaltrials.gov NCT01078090, NCT01077258, NCT01111240.
31471819 Assessment of interstitial lung disease among black rheumatoid arthritis patients. 2019 Dec BACKGROUND: Conflicting reports exist regarding the racial and the gender distribution of rheumatoid arthritis-related interstitial lung disease (RA-ILD). In a major population study of predominately Whites, RA-ILD was reported mainly among smoker middle-aged men. However, recent data suggest that the disease is that of elderly women. Our study aimed to assess the prevalence and identify the gender differences and clinical characteristics of RA-ILD in a predominantly Black population. METHODS: Cross-sectional analysis of data obtained from the records of 1142 patients with RA diagnosis by ICD codes of which 503 cases met the inclusion criteria for the study. Eighty-six patients had chronic respiratory symptoms of cough and dyspnea and were further assessed by our multidisciplinary group of investigators. Thirty-two subjects with an established diagnosis of rheumatoid arthritis met the diagnostic criteria for interstitial lung disease. RESULTS: Of the 32 patients with RA-ILD, mean age was 62.6 ± 2.2 (± SEM), 93.7% were females, and 89% Blacks with a BMI = 29.2 (Kg/m(2)). Usual interstitial pneumonia (UIP) was found in 24/32 (75%) of the cases. Seventy-two percent of the RA-ILD patient had seropositive RA. Smoking history was reported in 31.3% of the cohort, gastroesophageal reflux disease (GERD) in 32.3%, and cardiovascular disease (CVD) risk factors in 65.6%. CONCLUSION: Our study indicates RA-ILD among Blacks is predominantly a disease of elderly females with higher rates of GERD and CVD risk factors. Further studies are needed to identify the pathogenetic differences accounting for the gender distribution of RA-ILD among Black and White populations.Key Points• First study to assess ILD among predominantly Black RA patients.• The prevalence of RA-associated ILD was 6.36%, affecting mostly women in their sixth decade with seropositive disease.• COPD was the most common airway disease among non-RA-ILD Black population.• GERD was found in approximately one-third of patients with RA-associated ILD versus one-fifth of those RA patients without any lung disease.
30299241 Efficacy of tocilizumab monotherapy after response to combined tocilizumab and methotrexat 2019 May OBJECTIVES: The aim of the JUST-ACT study was to assess whether the add-on effect of tocilizumab (TCZ) to background methotrexate (MTX) observed in MTX-inadequate responders with active rheumatoid arthritis (RA), would be sustained when MTX is withdrawn. METHODS: A double-blind, parallel-group, phase 3 study in biologic-naïve RA patients with a disease activity score 28 (DAS28)>3.2 despite MTX which were treated with TCZ+MTX for an initial 16-week period. Patients who at week 16 achieved low disease activity (LDA) (DAS28≤3.2) were randomised to continue with TCZ+MTX or switch to TCZ + placebo (PBO) for an additional 12 weeks. The primary endpoint was the change in DAS28-ESR from the randomisation at week 16 to week 28. Non-inferiority was confirmed if the upper limit of the two-sided 95%CI for the treatment difference between TCZ+MTX and TCZ monotherapy groups was lower than the selected non-inferiority margin of 0.6. RESULTS: 261 patients completed the first 16 weeks of TCZ+MTX treatment and 165 were randomised (83 to TCZ+MTX and 82 to TCZ+PBO). For the primary endpoint, the adjusted treatment difference (95% CI) in mean change of DAS28-ESR was -0.06 (-0.40 to 0.27), and therefore the non-inferiority of switching to TCZ monotherapy versus continuing with TCZ+MTX was demonstrated. In both treatment groups, the percentage of patients in clinical remission from 16 to 28 weeks was similar as were the improvements in disease activity, functional disability and quality of life. CONCLUSIONS: In MTX non-responder patients achieving LDA with TCZ+MTX, switching to TCZ monotherapy is non-inferior to continuing the combination.
31526336 Novel Therapeutic Strategies for the Treatment of Chronic Diseases. 2019
30538031 Platelet-derived microparticles generated in vitro resemble circulating vesicles of patien 2019 Feb Patients with rheumatoid arthritis (RA) have increased amount of platelet-derived microparticles (PMPs) positive for citrullinated peptides (CPs) that form immune complexes (PMPs-ICs). Monocytes are important inflammatory mediators that play a role in the clearance of PMPs-ICs. We aimed to generate PMPs-ICs in vitro and determine its effect on monocytes from patients with RA and healthy individuals (HI). PMPs from patients showed platelet markers, mitochondria content, and phosphatidylserine exposure similar to PMPs from HI. However, patients had a higher frequency of IgG+ and CPs+ vesicles than HI. PMPs-ICs generated in vitro were similar to the circulating vesicles of patients with respect to IgG- and CPs-positivity. PMPs-ICs induced pro-inflammatory cytokines and CX3CR1 expression in monocytes from HI, and IL-10 and CD36 upregulation in monocytes from patients. These results suggest that PMPs-ICs induce activation of monocytes, with a pro-inflammatory response in HI and a more tolerant response in cells of patients with RA.
31213399 Targeting CD34(+) cells of the inflamed synovial endothelium by guided nanoparticles for t 2019 Sep Despite the advances in the treatment of rheumatoid arthritis (RA) achieved in the last few years, several patients are diagnosed late, do not respond to or have to stop therapy because of inefficacy and/or toxicity, leaving still a huge unmet need. Tissue-specific strategies have the potential to address some of these issues. The aim of the study is the development of a safe nanotechnology approach for tissue-specific delivery of drugs and diagnostic probes. CD34 (+) endothelial precursors were addressed in inflamed synovium using targeted biodegradable nanoparticles (tBNPs). These nanostructures were made of poly-lactic acid, poly-caprolactone, and PEG and then coated with a synovial homing peptide. Immunofluorescence analysis clearly demonstrated their capacity to selectively address CD34 (+) endothelial cells in synovial tissue obtained from human, mouse, and rat. Biodistribution studies in two different animal models of rheumatoid arthritis (antigen-induced arthritis/AIA and collagen-induced arthritis/CIA) confirmed the selective accumulation in inflamed joints but also evidenced the capacity of tBNP to detect early phases of the disease and the preferential liver elimination. The therapeutic effect of methotrexate (MTX)-loaded tBNPs were studied in comparison with conventional MTX doses. MTX-loaded tBNPs prevented and treated CIA and AIA at a lower dose and reduced administration frequency than MTX. Moreover, MTX-loaded tBNP showed a novel mechanism of action, in which the particles target and kill CD34 (+) endothelial progenitors, preventing neo-angiogenesis and, consequently, synovial inflammation. tBNPs represent a stable and safe platform to develop highly-sensitive imaging and therapeutic approaches in RA targeting specifically synovial neo-angiogenesis to reduce local inflammation.
31203231 Orthopedic Surgery in Rheumatoid Arthritis: Results from the Spanish National Registry of 2020 Mar OBJECTIVE: To analyze the trend of orthopedic surgery (OS) rates on patients with rheumatoid arthritis (RA). METHODS: Retrospective observational study based on information provided by the Spanish National System of Hospital Data Surveillance. All hospitalizations of patients with RA for orthopedic surgery [total hip arthroplasty (THA), total knee arthroplasty (TKA), arthrodesis, and upper limb arthroplasty (ULA)] during 1999-2015 were analyzed. The age-adjusted rate was calculated. Generalized linear models were used for trend analysis. RESULTS: There were 21,088 OS in patients over 20 years of age (77.9% women). OS rate adjusted by age was 754.63/100,000 RA patients/year (women 707.4, men 861.1). Neither an increasing nor a decreasing trend was noted for the total OS. However, trend and age interacted, so in the age ranges 20-40 years and 40-60 years, an annual reduction of 2.69% and 2.97%, respectively, was noted. In the age ranges over 80 years and 60-80 years, we noted an annual increase of 5.40% and 1.09%, respectively. The average age at time of OS increased 5.5 years during the period analyzed. For specific surgeries, a global annual reduction was noted in rates for arthrodesis. In THA, there was an annual reduction in patients under 80 years. In TKA and ULA, there was an annual reduction in patients under 60 years. CONCLUSION: Although the overall OS rate has not changed, there is a decrease in the rate of arthrodesis at all ages, THA in patients under 80 years of age, as well as TKA and ULA in patients under 60 years of age.
31774612 Patients and relatives coping with inflammatory arthritis: Care teamwork. 2020 Feb OBJECTIVE: To explore how patients and relatives experience and talk together about their life with inflammatory arthritis. DESIGN: Qualitative research. SETTING: A convenience sample was used. Participants were recruited in seven rheumatology departments in France. PARTICIPANTS: Patients with rheumatoid arthritis or spondyloarthritis, agreeing to participate in the study with a relative, age at least 18 years. DATA COLLECTION AND ANALYSIS: Two psychologists conducted face-to-face interviews with 20 patient-relative dyads (40 individuals). A thematic analysis followed a general inductive approach. RESULTS: Saturation was reached after interviews with 20 dyads. The analysis revealed four main themes: (a) disease 'lived' together: a new role for the relative (providing help in physical tasks, emotional support, acting as a driving force, having a role in medical care) and communication around the disease (not focusing on the disease); (b) impact of the disease on the relationship; (c) social impact of the disease on the dyad (social isolation); (d) difficulties and needs of the relative (need to better know the disease). CONCLUSION: This study has highlighted the importance of recognizing the role of the relative in the management of inflammatory arthritis disease, especially when medical decisions are shared with professionals. A joint approach to treatment is a basis for coping with the disease. This approach supposes (a) discussions about relatives' new roles to clarify them, (b) patients' and relatives' communication skills and (c) a good understanding of each other, which can be improved by providing information on the disease and coping strategies for both the patient and the relative.
