Characteristics associated with hospitalisation for COVID-19 in people with rheumatic disease: data from the COVID-19 Global Rheumatology Alliance physician-reported registry.

Abstract: Objectives COVID-19 outcomes in people with rheumatic diseases remain poorly understood. The aim was to examine demographic and clinical factors associated with COVID-19 hospitalisation status in people with rheumatic disease. Methods Case series of individuals with rheumatic disease and COVID-19 from the COVID-19 Global Rheumatology Alliance registry: 24 March 2020 to 20 April 2020. Multivariable logistic regression was used to estimate ORs and 95% CIs of hospitalisation. Age, sex, smoking status, rheumatic disease diagnosis, comorbidities and rheumatic disease medications taken immediately prior to infection were analysed. Results A total of 600 cases from 40 countries were included. Nearly half of the cases were hospitalised (277, 46%) and 55 (9%) died. In multivariable-adjusted models, prednisone dose ≥10 mg/day was associated with higher odds of hospitalisation (OR 2.05, 95% CI 1.06 to 3.96). Use of conventional disease-modifying antirheumatic drug (DMARD) alone or in combination with biologics/Janus Kinase inhibitors was not associated with hospitalisation (OR 1.23, 95% CI 0.70 to 2.17 and OR 0.74, 95% CI 0.37 to 1.46, respectively). Non-steroidal anti-inflammatory drug (NSAID) use was not associated with hospitalisation status (OR 0.64, 95% CI 0.39 to 1.06). Tumour necrosis factor inhibitor (anti-TNF) use was associated with a reduced odds of hospitalisation (OR 0.40, 95% CI 0.19 to 0.81), while no association with antimalarial use (OR 0.94, 95% CI 0.57 to 1.57) was observed. Conclusions We found that glucocorticoid exposure of ≥10 mg/day is associated with a higher odds of hospitalisation and anti-TNF with a decreased odds of hospitalisation in patients with rheumatic disease. Neither exposure to DMARDs nor NSAIDs were associated with increased odds of hospitalisation.

Physical Activity Outcomes of CHAMPS II A Physical Activity Promotion Program for Older Adults

Abstract: THE increasing burden of health problems and health care costs of our burgeoning older population requires more preventive approaches. Regular physical activity is a prominent strategy, based on a large body of evidence that it contributes substantially to the health, functioning, and quality of life of older adults (1–3). Physical activity may also be associated with less frequent utilization of health services (4–7). One is never too old to derive benefits from regular physical activity. Indeed, those who are sedentary or weak often gain the most health benefit by becoming more active (8–10). Further, moderate-intensity physical activity is beneficial (11,12) and easier for older adults to adhere to than vigorous activity (13). Most older adults, however, remain significantly underactive (2). Only about 25% of men and 20% of women aged 65 years and older meet the national guidelines for regular physical activity (2). In three national data sets, among those aged 65 to 74, 28% to 37% of women and 18% to 33% of men reported no participation (2). Among those aged 75 and older, 38% to 54% of women and 27% to 38% of men reported no participation in any leisure time physical activity. A critical next step is to implement practical and inclusive community-based programs to increase the physical activity levels of sedentary and underactive older adults. Most physical activity studies of older adults focus on examining health or fitness outcomes of various physical activity prescriptions or protocols, with physical activity as the independent variable. Very few have been designed specifically to change the lifestyle of older adults, that is, to help participants make regular physical activity and/or exercise a routine part of their lives (14). In such studies, the independent variable is whether or not they received a program of support for lifestyle changes (15). Participants in such programs choose the activity or set of activities they would like to do (with guidance) and set their own goals for increasing activity. This feature of choice enables individual preferences, which vary among older adults (16,17), to be taken into account, as well as readiness to change (18). This article examines the effectiveness of the Community Healthy Activities Model Program for Seniors (CHAMPS II) a lifestyle program based on the personal choice model that promotes increased physical activity levels. We evaluate the physical activity outcomes of this program using a randomized design and determine whether the program worked equally well for subgroups likely to have more difficulty changing their physical activity behavior (e.g., completely sedentary, overweight participants).

Associations of baseline use of biologic or targeted synthetic DMARDs with COVID-19 severity in rheumatoid arthritis: Results from the COVID-19 Global Rheumatology Alliance physician registry

Abstract: Objective To investigate baseline use of biologic or targeted synthetic (b/ts) disease-modifying antirheumatic drugs (DMARDs) and COVID-19 outcomes in rheumatoid arthritis (RA). Methods We analysed the COVID-19 Global Rheumatology Alliance physician registry (from 24 March 2020 to 12 April 2021). We investigated b/tsDMARD use for RA at the clinical onset of COVID-19 (baseline): abatacept (ABA), rituximab (RTX), Janus kinase inhibitors (JAKi), interleukin 6 inhibitors (IL-6i) or tumour necrosis factor inhibitors (TNFi, reference group). The ordinal COVID-19 severity outcome was (1) no hospitalisation, (2) hospitalisation without oxygen, (3) hospitalisation with oxygen/ventilation or (4) death. We used ordinal logistic regression to estimate the OR (odds of being one level higher on the ordinal outcome) for each drug class compared with TNFi, adjusting for potential baseline confounders. Results Of 2869 people with RA (mean age 56.7 years, 80.8% female) on b/tsDMARD at the onset of COVID-19, there were 237 on ABA, 364 on RTX, 317 on IL-6i, 563 on JAKi and 1388 on TNFi. Overall, 613 (21%) were hospitalised and 157 (5.5%) died. RTX (OR 4.15, 95% CI 3.16 to 5.44) and JAKi (OR 2.06, 95% CI 1.60 to 2.65) were each associated with worse COVID-19 severity compared with TNFi. There were no associations between ABA or IL6i and COVID-19 severity. Conclusions People with RA treated with RTX or JAKi had worse COVID-19 severity than those on TNFi. The strong association of RTX and JAKi use with poor COVID-19 outcomes highlights prioritisation of risk mitigation strategies for these people.

Association between etanercept use and employment outcomes among patients with rheumatoid arthritis.

Abstract: Objective To assess the association between use of etanercept and employment outcomes among patients with rheumatoid arthritis (RA). Methods In 1999, 497 RA patients of working ages (18–64 years) reported their employment status in the year of diagnosis and as of the study year, in structured telephone interviews. Of these, 238 had been in clinical trials of etanercept and were currently taking that medication, while 259 were members of an observational study and were not taking etanercept. We used regression techniques to estimate whether employment outcomes in 1999 (employed versus not and, among the employed, hours of work per week, weeks of work per year, and hours of work per year) among the 379 of the 497 patients who were employed at the time of diagnosis were associated with etanercept use, with and without adjustment for demographic characteristics, RA status, overall health status, and the nature of the job held at the time of diagnosis. Results At the time of diagnosis, 75% of RA patients from the observational study who did not take etanercept and 77% of those who did take the medication were employed. By 1999, among those employed at diagnosis, 55% of the former group and 71% of the latter were employed (difference 16 percentage points). After adjustment for demographics, overall health status, duration of RA, RA status, and occupation and industry, the difference widened to 20 percentage points. Among all who were employed at the time of diagnosis, those from the etanercept clinical trials worked an average of 5.4 more hours per week in 1999; after adjustment, the etanercept group worked 7.4 more hours per week. Conclusion Among all persons who were employed at the time of RA diagnosis, having been in the etanercept clinical trials was associated with higher employment rates in 1999 and a greater number of hours per week of work in that year, suggesting that a randomized trial to establish the relationship between treatment and employment outcomes is now warranted.

The impact of functional status and change in functional status on mortality over 18 years among persons with rheumatoid arthritis.

Abstract: OBJECTIVE: To calculate mortality rate associated with rheumatoid arthritis (RA), to estimate the effect of initial functional status and of change in functional status on mortality among persons with RA, and to compare the mortality experience of such persons to that of the US population. METHODS: The study used a prospective panel of 1269 persons followed for a mean of 8.4 years (median 7 yrs, interquartile range 3-12, maximum 18). Mortality status was ascertained from contacts with next of kin, study physicians, and search of the National Death Index. The Kaplan-Meier method was used to calculate the proportion dying in each time interval, with and without stratification for initial functional status [Health Assessment Questionnaire (HAQ) score] or average change in functional status. Cox proportional hazards regression was used to establish the effect of functional status, demographic characteristics, and health status on mortality risk. RESULTS: There were 270 deaths among the 1269 persons with RA. After 18 years of followup the overall death rate was 39%. The death rates in the best through worst initial quartiles of HAQ score were 29, 33, 44, and 54%. The death rate was 51% among persons with declining HAQ score versus 31 and 32% among those with no change or improvement in this measure, respectively. Demographic and health status did not reduce the effect of HAQ or average change in HAQ on mortality risk. Compared to the US population, the persons with RA had a standardized mortality rate of 1.32. CONCLUSION: The persons with RA in this study had elevated mortality rates. Poor initial functional status and declining functional status significantly increased mortality risk among these persons with RA.

Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study

Abstract: Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

Treating rheumatoid arthritis to target: recommendations of an international task force

Abstract: Aiming at therapeutic targets has reduced the risk of organ failure in many diseases such as diabetes or hypertension. Such targets have not been defined for rheumatoid arthritis (RA).

Treating rheumatoid arthritis to target: recommendations of an international task force (vol 69, pg 631, 2010)

Abstract: Background Aiming at therapeutic targets has reduced the risk of organ failure in many diseases such as diabetes or hypertension. Such targets have not been defined for rheumatoid arthritis (RA). Objective To develop recommendations for achieving optimal therapeutic outcomes in RA. Methods A task force of rheumatologists and a patient developed a set of recommendations on the basis of evidence derived from a systematic literature review and expert opinion; these were subsequently discussed, amended and voted upon by >60 experts from various regions of the world in a Delphi-like procedure. Levels of evidence, strength of recommendations and levels of agreement were derived. Results The treat-to-target activity resulted in 10 recommendations. The treatment aim was defined as remission with low disease activity being an alternative goal in patients with long-standing disease. Regular follow-up (every 1–3 months during active disease) with appropriate therapeutic adaptation to reach the desired state within 3 to a maximum of 6 months was recommended. Follow-up examinations ought to employ composite measures of disease activity which include joint counts. Additional items provide further details for particular aspects of the disease. Levels of agreement were very high for many of these recommendations (≥9/10). Conclusion The 10 recommendations are supposed to inform patients, rheumatologists and other stakeholders about strategies to reach optimal outcomes of RA based on evidence and expert opinion.

Effect of Structured Physical Activity on Prevention of Major Mobility Disability in Older Adults: The LIFE Study Randomized Clinical Trial

Abstract: Importance In older adults reduced mobility is common and is an independent risk factor for morbidity, hospitalization, disability, and mortality. Limited evidence suggests that physical activity may help prevent mobility disability; however, there are no definitive clinical trials examining whether physical activity prevents or delays mobility disability. Objective To test the hypothesis that a long-term structured physical activity program is more effective than a health education program (also referred to as a successful aging program) in reducing the risk of major mobility disability. Design, Setting, and Participants The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicenter, randomized trial that enrolled participants between February 2010 and December 2011, who participated for an average of 2.6 years. Follow-up ended in December 2013. Outcome assessors were blinded to the intervention assignment. Participants were recruited from urban, suburban, and rural communities at 8 centers throughout the United States. We randomized a volunteer sample of 1635 sedentary men and women aged 70 to 89 years who had physical limitations, defined as a score on the Short Physical Performance Battery of 9 or below, but were able to walk 400 m. Interventions Participants were randomized to a structured, moderate-intensity physical activity program (n = 818) conducted in a center (twice/wk) and at home (3-4 times/wk) that included aerobic, resistance, and flexibility training activities or to a health education program (n = 817) consisting of workshops on topics relevant to older adults and upper extremity stretching exercises. Main Outcomes and Measures The primary outcome was major mobility disability objectively defined by loss of ability to walk 400 m. Results Incident major mobility disability occurred in 30.1% (246 participants) of the physical activity group and 35.5% (290 participants) of the health education group (hazard ratio [HR], 0.82 [95% CI, 0.69-0.98], P = .03). Persistent mobility disability was experienced by 120 participants (14.7%) in the physical activity group and 162 participants (19.8%) in the health education group (HR, 0.72 [95% CI, 0.57-0.91]; P = .006). Serious adverse events were reported by 404 participants (49.4%) in the physical activity group and 373 participants (45.7%) in the health education group (risk ratio, 1.08 [95% CI, 0.98-1.20]). Conclusions and Relevance A structured, moderate-intensity physical activity program compared with a health education program reduced major mobility disability over 2.6 years among older adults at risk for disability. These findings suggest mobility benefit from such a program in vulnerable older adults. Trial Registration clinicaltrials.gov Identifier:NCT01072500

Interventions for promoting physical activity

Abstract: Background Little is known about the effectiveness of strategies to enable people to achieve and maintain recommended levels of physical activity. Objectives To assess the effectiveness of interventions designed to promote physical activity in adults aged 16 years and older, not living in an institution. Search methods We searched The Cochrane Library (issue 1 2005), MEDLINE, EMBASE, CINAHL, PsycLIT, BIDS ISI, SPORTDISCUS, SIGLE, SCISEARCH (from earliest dates available to December 2004). Reference lists of relevant articles were checked. No language restrictions were applied. Selection criteria Randomised controlled trials that compared different interventions to encourage sedentary adults not living in an institution to become physically active. Studies required a minimum of six months follow up from the start of the intervention to the collection of final data and either used an intention-to-treat analysis or, failing that, had no more than 20% loss to follow up. Data collection and analysis At least two reviewers independently assessed each study quality and extracted data. Study authors were contacted for additional information where necessary. Standardised mean differences and 95% confidence intervals were calculated for continuous measures of self-reported physical activity and cardio-respiratory fitness. For studies with dichotomous outcomes, odds ratios and 95% confidence intervals were calculated. Main results The effect of interventions on self-reported physical activity (19 studies; 7598 participants) was positive and moderate (pooled SMD random effects model 0.28 95% CI 0.15 to 0.41) as was the effect of interventions (11 studies; 2195 participants) on cardio-respiratory fitness (pooled SMD random effects model 0.52 95% CI 0.14 to 0.90). There was significant heterogeneity in the reported effects as well as heterogeneity in characteristics of the interventions. The heterogeneity in reported effects was reduced in higher quality studies, when physical activity was self-directed with some professional guidance and when there was on-going professional support. Authors' conclusions Our review suggests that physical activity interventions have a moderate effect on self-reported physical activity, on achieving a predetermined level of physical activity and cardio-respiratory fitness. Due to the clinical and statistical heterogeneity of the studies, only limited conclusions can be drawn about the effectiveness of individual components of the interventions. Future studies should provide greater detail of the components of interventions.
