The Association Between Yoga Use, Physical Function, and Employment in Adults With Rheumatoid Arthritis.

ABSTRACT: Mind-body exercises such as yoga offer patients with rheumatoid arthritis (RA) a symptom management strategy for improving physical and mental health. Studies have evaluated yoga to manage symptoms of RA and improve physical function; however, none has examined the relationship between yoga and work status in adults with RA. The objective was to describe differences in RA symptomatology, physical function scores, and work status between adults with RA who participate in yoga and those who do not. This cross-sectional study surveyed adults with rheumatologist-diagnosed RA regarding yoga use in the past year, symptoms, physical function, and work status. Differences between yoga and non-yoga participation groups were assessed with 2-sided t tests or Pearson ? tests. Multivariate linear regression analyses were conducted to identify significant associations between yoga participation and primary outcomes. The sample included 398 adults with RA; 88% were females, 66% were white, mean age 61.8 years, mean disease duration 24.8 years; 10.6% participated in yoga. Vinyasa, Bikram, Hatha, Iyengar, and restorative yoga styles were practiced, mostly in a group setting. Yoga participants were significantly more likely to work full-time, less likely to be unable to work due to disability, and had better physical function. These findings characterize yoga practice and practitioners among adults with RA. In adults with RA, yoga participation is associated with full-time work status and better physical function than nonparticipation. This study adds additional information to the growing body of literature about adults with RA who practice yoga.

Project description:IntroductionWe investigated whether rheumatoid arthritis (RA)-related autoantibodies were associated with abnormalities on pulmonary function tests (PFTs).MethodsWe studied RA serostatus and PFT abnormalities within a RA registry. RA serostatus was assessed by research assays for cyclic citrullinated peptide (CCP) and rheumatoid factor (RF). Outcomes were abnormalities on clinically indicated PFTs, including restriction, obstruction, and diffusion abnormality. Logistic regression was used to obtain ORs and 95% CIs for the PFT abnormalities by RA serologic phenotypes independent of lifestyle and RA characteristics.ResultsAmong 1272 analyzed subjects, mean age was 56.3 years (SD 14.1), 82.2% were female, and 69.5% were seropositive. There were 100 subjects with abnormal PFTs. Compared with seronegativity, seropositivity was associated with increased odds of any PFT abnormality (multivariable OR 2.29, 95% CI 1.30-4.03). When analyzing type of PFT abnormality, seropositivity was also associated with restriction, obstruction, and diffusion abnormalities; multivariable ORs were 2.48 (95% CI 1.26-4.87), 3.12 (95% CI 1.28-7.61), and 2.30 (95% CI 1.09-4.83), respectively. When analyzing by CCP and RF status, the associations were stronger for RF+ than for CCP+ (any PFT abnormality OR 1.99, 95% CI 1.21-3.27 for RF+ vs. RF-; OR 1.67, 95% CI 1.03-2.69 for CCP+ vs. CCP-) with a dose effect of higher RF titer increasing odds for each PFT abnormality (p for trend < 0.05).ConclusionsSeropositive RA patients had two-fold increased risk for abnormalities on PFTs performed for clinical indications compared with seronegative RA. Patients with seropositive RA, particularly those with high-titer RF positivity, may be more likely to have obstructive and restrictive abnormalities, independent of smoking.Key points• Due to the known excess pulmonary morbidity/mortality in RA, we studied the relationship of rheumatoid arthritis (RA)-related autoantibodies with pulmonary function test (PFT) abnormalities using a large RA registry.• We evaluated whether presence and levels of cyclic citrullinated peptide (CCP) and rheumatoid factor (RF) were associated with restriction, obstruction, and diffusion abnormalities on PFTs among 1272 subjects with RA.• Seropositivity was associated with two-fold increased risk for any PFT abnormality, independent of confounders including smoking. Higher titers of RF conferred greatest risk for all PFT outcomes: obstruction, restriction, and diffusion abnormality.• These results provide evidence that patients with RA should be closely monitored for pulmonary involvement, particularly those with high-titer RF seropositivity.

Project description:Purpose: Rheumatoid arthritis (RA) is a pervasive inflammatory autoimmune disease that seriously impairs human health and requires more effective non-pharmacologic treatment approaches. This study aims to systematically review and evaluate the efficacy of yoga for patients with RA. Methods: Medline (through PubMed), Cochrane Library, EMBASE (through SCOPUS), and Web of Science database were screened through for articles published until 20 July 2020. Randomized controlled trials (RCTs) of yoga in patients with RA were included. Outcomes measures were pain, physical function, disease activity, inflammatory cytokines, and grip strength. For each outcome, standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated. Result: Ten trials including 840 patients with RA aged 30-70 years were identified, with 86% female participants. Meta-analysis revealed a statistically significant overall effect in favor of yoga for physical function (HAQ-DI) (5 RCTs; SMD = -0.32, 95% CI -0.58 to -0.05, I 2 = 15%, P = 0.02), disease activity (DAS-28) (4 RCTs; SMD = -0.38, 95% CI -0.71 to -0.06, I 2 = 41%, P = 0.02) and grip strength (2 RCTs; SMD = 1.30, 95% CI 0.47-2.13, I 2 = 63%, P = 0.002). No effects were found for pain, tender joints, swollen joints count or inflammatory cytokines (i.e., CRP, ESR, IL-6, and TNF-α). Summary: The findings of this meta-analysis indicate that yoga may be beneficial for improving physical function, disease activity, and grip strength in patients with RA. However, the balance of evidence showed that yoga had no significant effect in improving pain, tender joints, swollen joints count, and inflammatory cytokines in patients suffering from RA. Considering methodological limitations, small sample size, and low-quality, we draw a very cautious conclusion in the results of the estimate of the effect. High-quality and large-scale RCTs are urgently needed in the future, and the real result may be substantially different.
