Dyspnea assessment and pulmonary hypertension in patients with systemic sclerosis: Utility of the University of California, San Diego, Shortness of Breath Questionnaire

Objective The University of California in San Diego Shortness of Breath Questionnaire (UCSD SOBQ) has been used to assess dyspnea‐related activity limitation in patients with airway and parenchymal lung disease. We sought to assess the construct validity and responsiveness of the UCSD SOBQ in systemic sclerosis (SSc; scleroderma) patients with incident pulmonary hypertension (PH) and those at high risk of developing PH. Methods We used data from 179 patients enrolled in the Pulmonary Hypertension Assessment and Recognition of Outcomes in Scleroderma Registry with pre‐PH (defined by criteria on pulmonary function tests and/or echocardiogram) or definite PH with mean pulmonary artery pressure ≥25 mm Hg by right‐sided heart catheterization within 6 months of enrollment. For this analysis, we included those subjects with complete data for self‐reported measures at baseline and at 12 months. Results At baseline, the UCSD SOBQ had strong correlations in the expected direction with the disability index (DI) of the Health Assessment Questionnaire (HAQ) (r = 0.71, P < 0.0001), dyspnea assessment by visual analog scale (r = 0.71, P < 0.0001), and the Short Form 36 (SF‐36) health survey physical component summary (PCS) score (r = −0.77, P < 0.0001), as well as a moderate correlation with the 6‐minute walk test distance (r = −0.33, P < 0.0001), Borg dyspnea score (r = 0.47, P < 0.0001), and diffusing capacity of carbon monoxide (r = −0.33, P < 0.0001). Change in the UCSD SOBQ at 12 months correlated in the expected direction with change in the HAQ DI (r = 0.54, P < 0.0001) and change in the SF‐36 PCS (r = −0.44, P < 0.0001). Multivariate analysis adjusting for age, sex, and race identified male sex as a significant predictor of death (odds ratio [OR] 7.00, 95% confidence interval [95% CI] 1.55–31.76), while the UCSD SOBQ showed a strong trend toward significance (OR 1.82, 95% CI 0.97–3.41). Conclusions The UCSD SOBQ demonstrates good construct validity and responsiveness to change in SSc patients with pulmonary vascular disease.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/96723/1/21827_ftp.pd

Valuation of scleroderma and psoriatic arthritis health states by the general public

<p>Abstract</p> <p>Objective</p> <p>Psoriatic arthritis (PsA) and scleroderma (SSc) are chronic rheumatic disorders with detrimental effects on health-related quality of life. Our objective was to assess health values (utilities) from the general public for health states common to people with PsA and SSc for economic evaluations.</p> <p>Methods</p> <p>Adult subjects from the general population in a Midwestern city (N = 218) completed the SF-12 Health Survey and computer-assisted 0-100 rating scale (RS), time trade-off (TTO, range: 0.0-1.0) and standard gamble (SG, range: 0.0-1.0) utility assessments for several hypothetical PsA and SSc health states.</p> <p>Results</p> <p>Subjects included 135 (62%) females, 143 (66%) Caucasians, and 62 (28%) African-Americans. The mean (SD) scores for the SF-12 Physical Component Summary scale were 52.9 (8.3) and for the SF-12 Mental Component Summary scale were 49.0 (9.1), close to population norms. The mean RS, TTO, and SG scores for PsA health states varied with severity, ranging from 20.2 to 63.7 (14.4-20.3) for the RS 0.29 to 0.78 (0.24-0.31) for the TTO, and 0.48 to 0.82 (0.24-0.34) for the SG. The mean RS, TTO, and SG scores for SSc health states were 25.3-69.7 (15.2-16.3) for the RS, 0.36-0.80 (0.25-0.31) for the TTO, and 0.50-0.81 (0.26-0.32) for the SG, depending on disease severity.</p> <p>Conclusion</p> <p>Health utilities for PsA and SSc health states as assessed from the general public reflect the severity of the diseases. These descriptive findings could have implications regarding comparative effectiveness research for tests and treatments for PsA and SSc.</p

The patient experience of Raynaud's phenomenon in systemic sclerosis

RP is the most common manifestation of SSc and a major cause of disease-related morbidity. This review provides a detailed appraisal of the patient experience of SSc-RP and potential implications for disease classification, patient-reported outcome instrument development and SSc-RP clinical trial design. The review explores the clinical features of SSc-RP, the severity and burden of SSc-RP symptoms and the impact of SSc-RP on function, work and social participation, body image dissatisfaction and health-related quality of life in SSc. Where management of SSc-RP is concerned, the review focuses on the 'patient experience' of interventions for SSc-RP, examining geographic variation in clinical practice and potential barriers to the adoption of treatment recommendations concerning best-practice management of SSc-RP. Knowledge gaps are highlighted that could form the focus of future research. A more thorough understanding of the patient experience could support the development of novel reported outcome instruments for assessing SSc-RP

Significance of sex in achieving sustained remission in the consortium of rheumatology researchers of north america cohort of rheumatoid arthritis patients

Objective To determine whether men with rheumatoid arthritis (RA) are more likely to achieve remission compared to women. Methods RA patients enrolled in the Consortium of Rheumatology Researchers of North America (CORRONA) cohort between October 2001 and January 2010 were selected for the present analyses. Detailed clinical, demographic, and drug utilization data were available at enrollment (baseline) and at subsequent followup visits. We examined the influence of sex on the Clinical Disease Activity Index remission score (≤2.8) using sustained remission or point remission as the primary outcome measure in multivariate stepwise logistic regression models. We stratified the data by RA duration at baseline (≤2 years or >2 years) to investigate whether RA duration had differential effects on remission in men and women. Results A total of 10,299 RA patients (2,406 men and 7,893 women) were available for this study. In both early and established RA, women had more severe disease at baseline with worse disease activity measures, modified Health Assessment Questionnaire disability index score, pain on a visual analog scale, and depression. Women were also more likely to have been treated with disease‐modifying antirheumatic drugs and anti–tumor necrosis factor therapy compared to men. In the regression models, male sex was associated with sustained remission in early RA (odds ratio [OR] 1.38, 95% confidence interval [95% CI] 1.07–1.78, P = 0.01), but not in established RA. However, for point remission, an inverse association was observed with male sex in established RA (OR 0.65, 95% CI 0.48–0.87, P = 0.005) and not in early RA. Conclusion Within the large real‐life CORRONA cohort of RA patients, men were more likely to achieve sustained remission compared to women in early RA, although not in established RA.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/94462/1/21762_ftp.pd

Minimal Clinically Important Differences for the Modified Rodnan Skin Score: Results from the Scleroderma Lung Studies (SLS-I and SLS-II)

Abstract Objective This study aimed to assess the minimal clinically important differences (MCIDs) for the modified Rodnan skin score (mRSS) using combined data from the Scleroderma Lung Studies (I and II). Methods MCID estimates for the mRSS at 12 months were calculated using three anchors: change in scores on the Health Assessment Questionnaire- Disability Index from baseline to 12 months, change in scores on the Patient Global Assessment from baseline to 12 months, and answer at 12 month for the Short Form-36 health transition question “Compared to one year ago, how would you rate your health in general now?” We determined the mRSS MCID estimates for all participants and for those with diffuse cutaneous systemic sclerosis (dcSSc). We then assessed associations between MCID estimates of mRSS improvement and patient-reported outcomes, using Student’s t test to compare the mean differences in patient outcomes between those who met the MCID improvement criteria versus those who did not meet the improvement criteria. Results The mean (SD) mRSS at baseline was 14.75 (10.72) for all participants and 20.93 (9.61) for those with dcSSc. The MCID estimate for mRSS improvement at 12 months ranged from 3 to 4 units for the overall group (improvement of 20–27% from baseline) and was 5 units for those with dcSSc (improvement of 24% from baseline). Those who met the mRSS MCID improvement criteria had statistically significant improvements in scores on the Short Form-36 Physical Component Summary, the Transition Dyspnea Index, and joint contractures at 12 months. Conclusion MCID estimates for the mRSS were 3–4 units for all participants and 5 units for those with dcSSc. These findings are consistent with previously reported MCID estimates for systemic sclerosis.https://deepblue.lib.umich.edu/bitstream/2027.42/147346/1/13075_2019_Article_1809.pd

Continued treatment with nintedanib in patients with systemic sclerosis-associated interstitial lung disease: data from SENSCIS-ON

OBJECTIVES In the SENSCIS trial in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD), nintedanib reduced the rate of decline in forced vital capacity (FVC) versus placebo, with adverse events that were manageable for most patients. An open-label extension trial, SENSCIS-ON, is assessing safety and FVC decline during longer term nintedanib treatment. METHODS Patients who completed the SENSCIS trial or a drug-drug interaction (DDI) study of nintedanib and oral contraceptive on treatment were eligible to enter SENSCIS-ON. Adverse events and changes in FVC over 52 weeks of SENSCIS-ON were assessed in patients who received nintedanib in SENSCIS and continued nintedanib in SENSCIS-ON ('continued nintedanib' group) and in patients who received placebo in SENSCIS and initiated nintedanib in SENSCIS-ON or who received nintedanib for ≤28 days in the DDI study ('initiated nintedanib' group). RESULTS There were 197 patients in the continued nintedanib group and 247 in the initiated nintedanib group. Diarrhoea was reported in 68.0% and 68.8% of patients in these groups, respectively. Adverse events led to discontinuation of nintedanib in 4.6% and 21.5% of the continued nintedanib and initiated nintedanib groups, respectively. Mean (SE) changes in FVC from baseline to week 52 of SENSCIS-ON were -58.3 (15.5) mL in the continued nintedanib group and -44.0 (16.2) mL in the initiated nintedanib group. CONCLUSIONS The safety profile of nintedanib over 52 weeks of SENSCIS-ON was consistent with that reported in SENSCIS. The change in FVC over 52 weeks of SENSCIS-ON was similar to that observed in the nintedanib group of SENSCIS
