Objectives To investigate the course of interstitial lung disease (ILD) and the effects of nintedanib in patients with limited cutaneous systemic sclerosis (lcSSc). Methods In the SENSCIS trial, patients with SSc-ILD were randomized to receive nintedanib or placebo. Patients who completed the SENSCIS trial were eligible to enter SENSCIS-ON, in which all patients received open-label nintedanib. Results Among 277 patients with lcSSc treated in the SENSCIS trial, the rate (s. e.) of decline in forced vital capacity (FVC; ml/year) over 52 weeks was −74.5 (19.2) in the placebo group and −49.1 (19.8) in the nintedanib group (difference: 25.3 [95% CI −28.9, 79.6]). Among 249 patients with data at week 52, mean (s. e.) change in FVC at week 52 was −86.4 (21.1) ml in the placebo group and −39.1 (22.2) ml in the nintedanib group. Among 183 patients with lcSSc who participated in SENSCIS-ON and had data at week 52, mean (s. e.) change in FVC from baseline to week 52 of SENSCIS-ON was −41.5 (24.0) ml in patients who took placebo in the SENSCIS trial and initiated nintedanib in SENSCIS-ON and −45.1 (19.1) ml in patients who took nintedanib in the SENSCIS trial and continued it in SENSCIS-ON. Conclusion Patients with lcSSc may develop progressive fibrosing ILD. By targeting pulmonary fibrosis, nintedanib slows decline in lung function in patients with lcSSc and ILD.

Objectives To explore prognostic and predictive markers of SSc-associated interstitial lung disease (SSc-ILD) outcomes in a phase 3 trial (focuSSced) and prognostic markers in a real-world cohort (SMART). Methods The focuSSced SSc-ILD subgroup included 68 of 106 placebo-treated and 68 of 104 tocilizumab-treated patients. The SMART cohort included 505 patients with SSc-ILD. Linear mixed-effect models were used to identify factors associated with change in forced vital capacity (FVC). Kaplan–Meier estimation and Cox regression were used for time-to-event analyses. Results In placebo-treated focuSSced patients, sex was a significant prognostic factor for FVC decline; males had increased risk for absolute decline ≥10% in percent-predicted FVC (ppFVC) and 0.22% faster weekly FVC decline than females (P   =  0.0001). FVC was 9.8% lower in patients with CRP >6 mg/ml vs those with CRP ≤6 mg/ml (P  = 0.0059). Tocilizumab reduced the risk for ≥10% decline in ppFVC in patients who were male, had earlier disease (<2 years duration), had IL-6 levels <10 pg/ml, or had anti-topoisomerase antibodies (ATA). In the SMART cohort, prognostic factors for ppFVC <70% were male sex, ATA, and low baseline FVC. Males had 3.3% lower FVC 1 year after disease onset (P  < 0.001) and 0.6% faster yearly decline (P  = 0.03) than females. Conclusion Prognostic markers in SSc-ILD were similar between focuSSced and SMART. Male sex and inflammatory markers were associated with lower FVC but IL-6 ≥10 pg/ml was not predictive of response to tocilizumab. Trial Registration ClinicalTrials.gov: NCT02453256.

Objective: We undertook this study to explore the efficacy, safety, and tolerability of ziritaxestat, a selective autotaxin inhibitor, in patients with early diffuse cutaneous systemic sclerosis (dcSSc). Methods: NOVESA was a 24‐week, multicenter, phase IIa, double‐blind, placebo‐controlled study. Adults with dcSSc were randomized to oral ziritaxestat 600 mg once daily or matching placebo. The primary efficacy end point was change from baseline in modified Rodnan skin score (MRSS) at week 24. Secondary end points assessed safety and tolerability; other end points included assessment of skin and blood biomarkers. Patients in NOVESA could enter a 104‐week open‐label extension (OLE). Results: Patients were randomized to ziritaxestat (n = 21) or placebo (n = 12). Reduction in MRSS was significantly greater in the ziritaxestat group versus the placebo group (–8.9 versus –6.0 units, respectively; P = 0.0411). Placebo patients switching to ziritaxestat in the OLE showed similar reductions in MRSS to those observed for ziritaxestat patients in the parent study. Ziritaxestat was well tolerated; the most frequent treatment‐related treatment‐emergent adverse events were headache and diarrhea. Circulating lysophosphatidic acid (LPA) C18:2 was significantly reduced, demonstrating ziritaxestat target engagement, and levels of fibrosis biomarkers were reduced in the blood. No differentially expressed genes were identified in skin biopsies. Significant changes in 109 genes were identified in blood samples. Conclusion: Ziritaxestat resulted in significantly greater reduction in MRSS at week 24 than placebo; no new safety signals emerged. Biomarker analysis suggests ziritaxestat may reduce fibrosis. Modulation of the autotaxin/LPA pathway could improve skin involvement in patients with dcSSc.

Scleroderma is a rare, potentially fatal, clinically heterogeneous, systemic autoimmune connective tissue disorder that is characterized by progressive fibrosis of the skin and visceral organs, vasculopathy and immune dysregulation. The more severe form of the disease, diffuse cutaneous scleroderma (dcSSc), has no cure and limited treatment options. Haematopoietic stem cell transplantation has emerged as a potentially disease-modifying treatment but faces challenges such as toxicity associated with fully myeloablative conditioning and recurrence of autoimmunity. Novel cell therapies—such as mesenchymal stem cells, chimeric antigen receptor-based therapy, tolerogenic dendritic cells and facilitating cells—that may restore self-tolerance with more favourable safety and tolerability profiles are being explored for the treatment of dcSSc and other autoimmune diseases. This narrative review examines these evolving cell therapies. [ABSTRACT FROM AUTHOR]

Objective: Hand dysfunction is common in systemic sclerosis (SSc). We undertook this study to evaluate the capacity of autologous adipose‐derived regenerative cells (ADRCs) to improve hand function in SSc patients. Methods: The Scleroderma Treatment with Celution Processed Adipose Derived Regenerative Cells Trial was a prospective, randomized, double‐blind trial of ADRCs, in which ADRCs were obtained from patients with SSc by small‐volume adipose tissue harvest, and the fingers of each patient were injected with ADRCs. The primary end point was change in hand function at 24 and 48 weeks, assessed using the Cochin Hand Function Scale (CHFS). One of the secondary end points included the change in Health Assessment Questionnaire disability index (HAQ DI) at 48 weeks. Separate prespecified analyses were performed for patients with diffuse cutaneous SSc (dcSSc) and those with limited cutaneous SSc (lcSSc). Results: Eighty‐eight patients were randomized to receive ADRCs (n = 48 [32 patients with dcSSc and 16 with lcSSc]) or placebo (n = 40 [19 patients with dcSSc and 21 with lcSSc]). Change in hand function according to CHFS score was numerically higher for the ADRC group compared to the placebo group but did not achieve statistical significance (mean ± SD improvement in the CHFS score at 48 weeks 11.0 ± 12.5 versus 8.9 ± 10.5; P = 0.299). For patients with dcSSc, the between‐group difference in the CHFS at 48 weeks was 6.3 points (nominal P = 0.069). For the secondary end point, the dcSSc group exhibited a between‐group difference of 0.17 points in the HAQ DI (nominal P = 0.044) at 48 weeks. Of the ADRC‐treated patients with dcSSc, 52% reported improvement greater than the minimum clinically important difference for both CHFS and HAQ DI compared to 16% in the placebo group (nominal P = 0.016). Small‐volume adipose tissue harvest and ADRC treatment were well tolerated. Conclusion: While the primary end point of this trial was not achieved, efficacy trends were observed in patients with dcSSc. Adipose tissue harvest and ADRC injection were demonstrated to be feasible. Further clinical trials of this intervention in the setting of dcSSc are warranted. [ABSTRACT FROM AUTHOR]

Systemic sclerosis (SSc; scleroderma) has the highest individual mortality of all rheumatic diseases, and interstitial lung disease (ILD) is among the leading causes of SSc‐related death. Two drugs are now approved by the US Food and Drug Administration (FDA) and indicated for slowing the rate of decline in pulmonary function in patients with SSc‐associated ILD (SSc‐ILD): nintedanib (a tyrosine kinase inhibitor) and tocilizumab (the first biologic agent targeting the interleukin‐6 pathway in SSc). In addition, 2 generic drugs with cytotoxic and immunoregulatory activity, mycophenolate mofetil and cyclophosphamide, have shown comparable efficacy in a phase II trial but are not FDA‐approved for SSc‐ILD. In light of the heterogeneity of the disease, the optimal therapeutic strategy for the management of SSc‐ILD is still to be determined. The objectives of this review are 2‐fold: 1) review the body of research focused on the diagnosis and treatment of SSc‐ILD; and 2) propose a practical approach for diagnosis, stratification, management, and therapeutic decision‐making in this clinical context. This review presents a practical classification of SSc patients in terms of disease severity (subclinical versus clinical ILD) and associated risk of progression (low versus high risk). The pharmacologic and nonpharmacologic options for first‐ and second‐line therapy, as well as potential combination approaches, are discussed in light of the recent approval of tocilizumab for SSc‐ILD.

Objective: Pegloticase is used for the treatment of severe gout, but its use is limited by immunogenicity. This study was undertaken to evaluate whether mycophenolate mofetil (MMF) prolongs the efficacy of pegloticase. Methods: Participants were randomized 3:1 to receive 1,000 mg MMF twice daily or placebo for 14 weeks, starting 2 weeks before receiving pegloticase and continuing while receiving intravenous pegloticase 8 mg biweekly for 12 weeks. Participants then received pegloticase alone from week 12 to week 24. The primary end points were the proportion of patients who sustained a serum urate level of ≤6 mg/dl at 12 weeks and the rate of adverse events (AEs). Secondary end points included 24‐week durability of serum urate level ≤6 mg/dl. Fisher's exact test and Wilcoxon's 2‐sample test were used for analyses, along with Kaplan‐Meier estimates and log rank tests. Results: A total of 32 participants received ≥1 dose of pegloticase. Participants were predominantly men (88%), with a mean age of 55.2 years, mean gout duration of 13.4 years, and mean baseline serum urate level of 9.2 mg/dl. At 12 weeks, a serum urate level of ≤6 mg/dl was achieved in 19 (86%) of 22 participants in the MMF arm compared to 4 (40%) of 10 in the placebo arm (P = 0.01). At week 24, the serum urate level was ≤6 mg/dl in 68% of MMF‐treated patients versus 30% of placebo‐treated patients (P = 0.06), and rates of AEs were similar between groups, with more infusion reactions occurring in the placebo arm (30% versus 0%). Conclusion: Our findings indicate that MMF therapy with pegloticase is well tolerated and shows a clinically meaningful improvement in targeted serum urate level of ≤6 mg/dl at 12 and 24 weeks. This study suggests an innovative approach to pegloticase therapy in gout. [ABSTRACT FROM AUTHOR]

Objective: Data on the magnitude of benefit of modern therapies for pulmonary arterial hypertension (PAH) in connective tissue disease (CTD)–associated PAH are limited. In this study, we performed meta‐analyses of randomized, controlled trials (RCTs) and registries to quantify the benefit of these modern therapies in patients with CTD‐PAH. Methods: The PubMed and Embase databases were searched for articles reporting data from RCTs or registries published between January 1, 2000 and November 25, 2019. Eligibility criteria included multicenter studies with ≥30 CTD‐PAH patients. For an RCT to be included, the trial had to evaluate an approved PAH therapy, and long‐term risks of clinical morbidity and mortality or 6‐minute walk distance had to be reported. For a registry to be included, survival rates had to be reported. Random‐effects models were used to pool the data. Results: Eleven RCTs (total of 4,329 patients; 1,267 with CTD‐PAH) and 19 registries (total of 9,739 patients; 4,008 with CTD‐PAH) were included. Investigational therapy resulted in a 36% reduction in the risk of clinical morbidity/mortality events both in the overall PAH population (hazard ratio [HR] 0.64, 95% confidence interval [95% CI] 0.54, 0.75; P < 0.001) and in CTD‐PAH patients (HR 0.64, 95% CI 0.51, 0.81; P < 0.001) as compared to control subjects. The survival rate was lower in CTD‐PAH patients compared to all PAH patients (survival rate 62%, 95% CI 57, 67% versus 72%, 95% CI 69, 75% at 3 years). The survival rate in CTD‐PAH patients treated primarily after 2010 was higher than that in CTD‐PAH patients treated before 2010 (survival rate 73%, 95% CI 62, 81% versus 65%, 95% CI 59, 71% at 3 years). Conclusion: Modern therapy provides a similar reduction in morbidity/mortality risk in patients with CTD‐PAH when compared to the PAH population overall. Risk of death is higher in CTD‐PAH patients than in those with PAH overall, but survival has improved in the last 10 years, which may be related to increased screening and/or new treatment approaches. Early detection of PAH in patients with CTD and up‐front intensive treatment are warranted. [ABSTRACT FROM AUTHOR]

Objective: T cells play a key role in the pathogenesis of early systemic sclerosis. This study was undertaken to assess the safety and efficacy of abatacept in patients with diffuse cutaneous systemic sclerosis (dcSSc). Methods: In this 12‐month, randomized, double‐blind, placebo‐controlled trial, participants were randomized 1:1 to receive either subcutaneous abatacept 125 mg or matching placebo, stratified by duration of dcSSc. Escape therapy was allowed at 6 months for worsening disease. The coprimary end points were change in the modified Rodnan skin thickness score (MRSS) compared to baseline and safety over 12 months. Differences in longitudinal outcomes were assessed according to treatment using linear mixed models, with outcomes censored after initiation of escape therapy. Skin tissue obtained from participants at baseline was classified into intrinsic gene expression subsets. Results: Among 88 participants, the adjusted mean change in the MRSS at 12 months was −6.24 units for those receiving abatacept and −4.49 units for those receiving placebo, with an adjusted mean treatment difference of −1.75 units (P = 0.28). Outcomes for 2 secondary measures (Health Assessment Questionnaire disability index and a composite measure) were clinically and statistically significantly better with abatacept. The proportion of subjects in whom escape therapy was needed was higher in the placebo group relative to the abatacept group (36% versus 16%). In the inflammatory and normal‐like skin gene expression subsets, decline in the MRSS over 12 months was clinically and significantly greater in the abatacept group versus the placebo group (P < 0.001 and P = 0.03, respectively). In the abatacept group, adverse events occurred in 35 participants versus 40 participants in the placebo group, including 2 deaths and 1 death, respectively. Conclusion: In this phase II trial, abatacept was well‐tolerated, but change in the MRSS was not statistically significant. Secondary outcome measures, including gene expression subsets, showed evidence in support of abatacept. These data should be confirmed in a phase III trial. [ABSTRACT FROM AUTHOR]

Objective: We previously identified CYR61 as a histone deacetylase 5 (HDAC‐5)–repressed gene in systemic sclerosis (SSc; scleroderma) endothelial cells (ECs). When overexpressed, cysteine‐rich angiogenic inducer 61 (CYR‐61) promoted angiogenesis in SSc ECs. This study was undertaken to examine the role of CYR‐61 in fibrosis and determine the mechanisms involved in CYR‐61–mediated angiogenesis in SSc. Methods: Dermal ECs and fibroblasts were isolated from biopsy specimens from healthy subjects and patients with SSc. CYR‐61 level was determined by quantitative polymerase chain reaction, Western blotting, and enzyme‐linked immunosorbent assay. CYR‐61 was overexpressed using a CYR61 vector or knocked down using small interfering RNA, and functional and mechanistic studies were then conducted in fibroblasts and ECs. Results: Lower CYR61 messenger RNA levels were observed in dermal fibroblasts and ECs from SSc patients than in those from healthy controls. In SSc fibroblasts, overexpression of CYR‐61 led to significant reduction in the expression of profibrotic genes, including COL1A1 (P = 0.002) and ACTA2 (P = 0.04), and an increase in the expression of matrix‐degrading genes, including MMP1 (P = 0.002) and MMP3 (P =0.004), and proangiogenic VEGF (P = 0.03). The antifibrotic effect of CYR‐61 was further demonstrated by delay in wound healing, inhibition of gel contraction, inactivation of the transforming growth factor β pathway, and early superoxide production associated with senescence in SSc fibroblasts. In SSc ECs, overexpression of CYR‐61 led to increased production of vascular endothelial cell growth factor. The proangiogenic effects of CYR‐61 were mediated by signaling through αvβ3 receptors and downstream activation of AMP‐activated protein kinase, AKT, and the endothelial cell nitric oxide synthase/nitric oxide pathway system. Conclusion: CYR‐61, which is epigenetically regulated by HDAC‐5, is a potent antifibrotic and proangiogenic mediator in SSc. Therapeutic intervention to promote CYR‐61 activity or increase CYR‐61 levels might be of benefit in SSc. [ABSTRACT FROM AUTHOR]

SSc is a rare CTD that affects multiple organ systems, resulting in substantial morbidity and mortality. Evidence of interstitial lung disease (ILD) is seen in ∼80% of patients with SSc. Currently there is no approved disease-modifying treatment for ILD and few effective treatment options are available. CYC is included in treatment guidelines, but it has limited efficacy and is associated with toxicity. MMF is becoming the most commonly used medication in clinical practice in North America and the UK, but its use is not universal. Newer agents targeting the pathogenic mechanisms underlying SSc-ILD, including fibrotic and inflammatory pathways, lymphocytes, cell–cell and cell–extracellular membrane interactions, hold promise for better treatment outcomes, including improved lung function, patient-related outcomes and quality of life. Here we review ongoing trials of established and novel agents that are currently recruiting patients with SSc-ILD. [ABSTRACT FROM AUTHOR]

The authors discuss drug initiation and escalation strategies of vasodilator therapies for Raynaud's phenomenon (RP). Topics include basis of the decision to initiate and assess treatment response in RP, factor attributed to the success of treat to target (T2T) strategies in inflammatory arthritis, and key initial steps to the successful development of a T2T strategy for systemic sclerosis (SSc)-RP and digital vasculopathy.

Objectives. Patient acceptable symptom state (PASS) as an absolute state of well-being has shown promise as an outcome measure in many rheumatologic conditions. We aimed to assess whether PASS may be effective in active diffuse cutaneous SSc differentiating active from placebo. Methods. Data from the phase 2 Safety and Efficacy of Subcutaneous Tocilizumab in Adults with Systemic Sclerosis (faSScinate) trial were used, which compared tocilizumab (TCZ) vs placebo over 48 weeks followed by an open-label TCZ period to 96 weeks. Three different types of PASS questions were evaluated at weeks 8, 24, 48 and 96, including if a current state would be acceptable over time as a yes vs no response and Likert scales about how acceptable a current state is if remaining over time. Additional outcomes assessed included modified Rodnan skin score, HAQ disability index (HAQ-DI), physician and patient global assessments on a visual analogue scale, CRP and ESR. Results. The placebo group consisted of 44 patients and the TCZ group had 43 patients. At baseline, 33% achieved a PASS for all three PASS questions, with the proportion increasing to 69, 71 and 78%, respectively, at 96 weeks. Changes in PASS scores showed a moderately negative correlation with HAQ-DI and patient and physician global assessments visual analogue scales, which indicates expected improvements as PASS improved. The PASS question, 'Considering all of the ways your scleroderma has affected you, how acceptable would you rate your level of symptoms?' showed significant correlations with patient-reported outcomes and differentiating placebo vs TCZ at 48 weeks (P = 0.023). Conclusion. PASS may be used as a patient-centred outcome in SSc, especially as a 7-point Likert scale. Further validation is required to determine the utility as an outcome measure in trials and clinical practice. [ABSTRACT FROM AUTHOR]

Systemic sclerosis, also called scleroderma, is an immune-mediated rheumatic disease that is characterised by fibrosis of the skin and internal organs and vasculopathy. Although systemic sclerosis is uncommon, it has a high morbidity and mortality. Improved understanding of systemic sclerosis has allowed better management of the disease, including improved classification and more systematic assessment and follow-up. Additionally, treatments for specific complications have emerged and a growing evidence base supports the use of immune suppression for the treatment of skin and lung fibrosis. Some manifestations of the disease, such as scleroderma renal crisis, pulmonary arterial hypertension, digital ulceration, and gastro-oesophageal reflux, are now treatable. However, the burden of non-lethal complications associated with systemic sclerosis is substantial and is likely to become more of a challenge. Here, we review the clinical features of systemic sclerosis and describe the best practice approaches for its management. Furthermore, we identify future areas for development.

Patients with SSc have the highest mortality among the rheumatic diseases. In addition, SSc is associated with disfigurement, hand contractures, fatigue, poor sleep, severe RP with numbness and tingling of the fingers can lead to decrements in quality of life. This Points to Consider article provides practical considerations for design of trials for functional disability and other health-related quality-of-life issues. [ABSTRACT FROM AUTHOR]

Interstitial lung disease causes major morbidity and mortality in patients with systemic sclerosis (SSc-ILD). Large randomized clinical trials in SSc-ILD have provided important information regarding the feasibility, reliability and validity of outcome measures. Forced vital capacity percentage predicted should be considered as a primary outcome measure, with inclusion of appropriate radiological and patient-reported measures. We provide practical recommendations for trial design in SSc-ILD. [ABSTRACT FROM AUTHOR]

Background: The NIH-sponsored Patient-Reported Outcomes Measurement Information System (PROMIS) Gastrointestinal (GI) Symptoms scales were developed to assess patients' GI symptoms in clinical settings. Aims: To assess responsiveness to change and provide minimally important difference (MID) estimates for the PROMIS GI Symptoms scales. Methods: A sample of 256 GI outpatients self-administered the eight PROMIS GI Symptoms scales (gastroesophageal reflux, disrupted swallowing, diarrhea, bowel incontinence/soilage, nausea and vomiting, constipation, belly pain, and gas/bloating/flatulence) at two visits. Patient self-reported and physician-reported assessments of the subjects' overall GI condition were employed as change anchors. In addition, we prospectively assessed change at both visits using a GI-symptom anchor, the Gastrointestinal Symptom Rating Scale (GSRS). Responsiveness to change was assessed using F-statistics. The minimally changed group was those somewhat better or somewhat worse on the retrospective anchors and changing by one category on the modified GSRS (e.g., from slight to mild discomfort to moderate to moderately severe discomfort). Results: Responsiveness to change was statistically significant for 6 of 8 PROMIS scales using the self-report GI anchor, 3 of 8 scales using the physician-reported anchor, and 5 of 5 scales using the corresponding GSRS scales as anchors. The MID estimates for scales for improvement and worsening were about 0.5-0.6 SD using the GSRS anchor and generally larger in magnitude than the change for the 'about the same' group. Conclusions: The responsiveness and MID estimates provided here for the PROMIS GI Symptoms scales can aid in scale score interpretation in clinical trials and observational studies.

Background: Systemic sclerosis is a rare disabling autoimmune disease with few treatment options. The efficacy and safety of tocilizumab, an interleukin 6 receptor-α inhibitor, was assessed in the faSScinate phase 2 trial in patients with systemic sclerosis.Methods: We did this double-blind, placebo-controlled study at 35 hospitals in Canada, France, Germany, the UK, and the USA. We enrolled adults with progressive systemic sclerosis of 5 or fewer years' duration from first non-Raynaud's sign or symptom. Patients were randomly assigned (1:1) to weekly subcutaneous tocilizumab 162 mg or placebo. The primary endpoint was the difference in mean change from baseline in modified Rodnan skin score at 24 weeks. This study is registered with ClinicalTrials.gov, number NCT01532869.Findings: We enrolled 87 patients: 43 assigned to tocilizumab and 44 assigned to placebo. The least squares mean change in modified Rodnan skin score at 24 weeks was -3·92 in the tocilizumab group and -1·22 in the placebo group (difference -2·70, 95% CI -5·85 to 0·45; p=0·0915). The least squares mean change at 48 weeks was -6·33 in the tocilizumab group and -2·77 in the placebo group (treatment difference -3·55, 95% CI -7·23 to 0·12; p=0·0579). In one of several exploratory analyses, fewer patients in the tocilizumab group than in the placebo group had a decline in percent predicted forced vital capacity at 48 weeks (p=0·0373). However, we detected no significant difference in disability, fatigue, itching, or patient or clinician global disease severity. 42 (98%) of 43 patients in the tocilizumab group versus 40 (91%) of 44 in the placebo group had adverse events. 14 (33%) versus 15 (34%) had serious adverse events. Serious infections were more common in the tocilizumab group (seven [16%] of 43 patients) than in the placebo group (two [5%] of 44). One patient died in relation to tocilizumab treatment.Interpretation: Tocilizumab was not associated with a significant reduction in skin thickening. However, the difference was greater in the tocilizumab group than in the placebo group and we found some evidence of less decline in forced vital capacity. The efficacy and safety of tocilizumab should be investigated in a phase 3 trial before definitive conclusions can be made about its risks and benefits.Funding: F Hoffmann-La Roche, Genentech.

Objective. The aim was to evaluate the reliability, validity and responsiveness to change of the Gout Impact Scale (GIS), a disease-specific measure of patient-reported outcomes, in a multicentre longitudinal prospective cohort of gout patients. Methods. Subjects completed the GIS, a 24-item instrument with five scales: Concern Overall, Medication Side Effects, Unmet Treatment Need, Well-Being during Attack, and Concern Over Attack. The total GIS score was calculated by averaging the GIS scale scores. HAQ-Disability Index (HAQ-DI), Short Form (SF)-36 physical and mental component summaries (PCS and MCS) and physician and patient gout severity assessments were also completed. Reliability was assessed with Cronbach's a. Baseline GIS scores were compared in subjects with and without gout attacks in the past 3 months using Wilcoxon rank sum tests. Multivariate linear regression was used to evaluate predictors of total GIS. Pearson's correlation coefficients 0.24-0.36 were considered moderate and >0.37 considered large. The effect size for responsiveness to change was interpreted as follows: 0.20-0.49 small, 0.50-0.79 medium and >0.79 large. Results. In 147 subjects, reliability was acceptable for total GIS (0.93) and all GIS scales (0.82-0.94) except Medication Side Effects and Unmet Treatment Need. Total GIS and all scales except Medication Side Effects discriminated between subjects with and without recent gout attacks (P < 0.05). Total GIS showed moderate-to-large correlations with HAQ-DI, SF-36 PCS and MCS (0.33-0.46). Improvement in total GIS tracked with improved physician and patient severity scores. Worsening physician severity score and recent gout attack predicted worsening total GIS. Conclusion. Total GIS score is reliable, valid and responsive to change in patients with gout, and differentiates between subjects with and without recent gout attacks. [ABSTRACT FROM AUTHOR]

Importance: Digital ulcers in patients with systemic sclerosis are associated with pain and poor quality of life. Endothelin-1 promotes vasculopathy in systemic sclerosis after macitentan, an endothelin-1 blocker.Objective: To evaluate the efficacy of macitentan in reducing the number of new digital ulcers in patients with systemic sclerosis.Design, Setting, and Participants: Two international, randomized, double-blind, placebo-controlled trials (DUAL-1, DUAL-2) were conducted between January 2012 and February 2014. Participants were patients with systemic sclerosis and active digital ulcers at baseline. Target enrollment for each study was 285 patients.Interventions: Patients were randomized (1:1:1) to receive oral doses of 3 mg of macitentan, 10 mg of macitentan, or placebo once daily and stratified according to number of digital ulcers at baseline (≤3 or >3).Main Outcomes and Measures: The primary outcome for each trial was the cumulative number of new digital ulcers from baseline to week 16. Treatment effect was expressed as the ratio between treatment groups.Results: In DUAL-1, among 289 randomized patients (mean age 51.2 years; 85.8% women), 226 completed the study. The adjusted mean number of new digital ulcers per patient over 16 weeks was 0.94 in the 3-mg macitentan group (n = 95) and 1.08 in the 10-mg macitentan group (n = 97) compared with 0.85 in the placebo group (n = 97) (absolute difference, 0.09 [95% CI, -0.37 to 0.54] for 3 mg of macitentan vs placebo and 0.23 [-0.27 to 0.72] for 10 mg of macitentan vs placebo). Among 265 patients randomized in DUAL-2 (mean age 49.6 years; 81.9% women), 216 completed the study. In DUAL-2, the adjusted mean number of new digital ulcers was 1.44 in the 3-mg macitentan group (n = 88) and 1.46 in the 10-mg macitentan group (n = 88) compared with 1.21 in the placebo group (n = 89) (absolute difference, 0.23 [95% CI, -0.35 to 0.82] for 3 mg of macitentan vs placebo and 0.25 [95% CI, -0.34 to 0.84] for 10 mg of macitentan vs placebo). Adverse events more frequently associated with macitentan than with placebo were headache, peripheral edema, skin ulcer, anemia, upper respiratory tract infection, diarrhea, and nasopharyngitis.Conclusions and Relevance: Among patients with systemic sclerosis and active ischemic digital ulcers, treatment with macitentan did not reduce new digital ulcers over 16 weeks. These results do not support the use of macitentan for the treatment of digital ulcers in this patient population.Trial Registration: clinicaltrials.gov Identifiers: NCT01474109, NCT01474122.

Objective Early diffuse cutaneous systemic sclerosis (dcSSc) is characterized by rapid changes in the skin and internal organs. The objective of this study was to develop a composite response index in dcSSc (CRISS) for use in randomized controlled trials (RCTs). Methods We developed 150 paper patient profiles with standardized clinical outcome elements (core set items) using patients with dcSSc. Forty scleroderma experts rated 20 patient profiles each and assessed whether each patient had improved or not improved over a period of 1 year. Using the profiles for which raters had reached a consensus on whether the patients were improved versus not improved (79% of the profiles examined), we fit logistic regression models in which the binary outcome referred to whether the patient was improved or not, and the changes in the core set items from baseline to followup were entered as covariates. We tested the final index in a previously completed RCT. Results Sixteen of 31 core items were included in the patient profiles after a consensus meeting and review of test characteristics of patient-level data. In the logistic regression model in which the included core set items were change over 1 year in the modified Rodnan skin thickness score, the forced vital capacity, the patient and physician global assessments, and the Health Assessment Questionnaire disability index, sensitivity was 0.982 (95% confidence interval 0.982-0.983) and specificity was 0.931 (95% confidence interval 0.930-0.932), and the model with these 5 items had the highest face validity. Subjects with a significant worsening of renal or cardiopulmonary involvement were classified as not improved, regardless of improvements in other core items. With use of the index, the effect of methotrexate could be differentiated from the effect of placebo in a 1-year RCT ( P = 0.02). Conclusion We have developed a CRISS that is appropriate for use as an outcome assessment in RCTs of early dcSSc. [ABSTRACT FROM AUTHOR]

Objective: This phase 3 study was undertaken to investigate the efficacy and safety of lenabasum, a cannabinoid type 2 receptor agonist, in patients with diffuse cutaneous systemic sclerosis (dcSSc). Methods: A multinational double‐blind study was conducted in 365 dcSSc patients who were randomized and dosed 1:1:1 with lenabasum 20 mg, lenabasum 5 mg, or placebo, each twice daily and added to background treatments, including immunosuppressive therapies (IST). Results: The primary end point, the American College of Rheumatology combined response index in dcSSc (CRISS) at week 52 for lenabasum 20 mg twice a day versus placebo, was not met, with CRISS score of 0.888 versus 0.887 (P = 0.4972, using mixed models repeated measures [MMRM]). The change in the modified Rodnan skin thickness score (MRSS) at week 52 for lenabasum 20 mg twice a day versus placebo was −6.7 versus −8.1 (P = 0.1183, using MMRM). Prespecified analyses showed higher CRISS scores, greater improvement in MRSS, and lower decline in forced vital capacity in patients on background mycophenolate and those who were taking IST for ≤1 year. No deaths or excess in serious or severe adverse events related to lenabasum were observed. Conclusion: A benefit of lenabasum in dcSSc was not demonstrated. Most patients were treated with background IST, and treatment with mycophenolate mofetil in particular was associated with better outcomes. These findings support the use of IST in the treatment of dcSSc and highlight the challenge of demonstrating a treatment effect when investigational treatment is added to standard of care IST. These findings have relevance to trial design in SSc, as well as to clinical care. [ABSTRACT FROM AUTHOR]

Objective. SSc is clinically and aetiopathogenically heterogeneous. Consensus standards for more uniform trial design and selection of outcome measures are needed. The objective of this study was to develop evidence-based points to consider (PTCs) for future clinical trials in SSc.Methods. Thirteen international SSc experts experienced in SSc clinical trial design were invited to participate. One researcher with experience in systematic literature review and three trainees were also included. A systematic review using PubMed and the Cochrane Central Register of Controlled Trials was conducted and PTCs when designing clinical trials in SSc were developed. As part of that development we conducted an Internet-based Delphi exercise regarding the main points to be made in the consensus statement. Consensus was defined as achieving a median score of ≥7 of 9.Results. By consensus, the experts decided to develop PTCs for each individual organ system. The current document provides a unifying outline on PTCs regarding general trial design, inclusion/exclusion criteria and analysis. Consensus was achieved regarding all the main points of the PTCs.Conclusion. Using European League Against Rheumatism suggestions for PTCs, a general outline for PTCs for controlled clinical trials in SSc was developed. Specific outlines for individual organ systems are to be published separately. This general outline should lead to more uniform and higher-quality trials and clearly delineate areas where further research is needed. [ABSTRACT FROM PUBLISHER]

Background Pulmonary hypertension (PH)-targeted therapy in the setting of pulmonary fibrosis (PF) is controversial; the main clinical concern is worsening of systemic hypoxaemia. We sought to determine the effects of gentle initiation and chronic administration of parenteral treprostinil on right heart function in patients with PF associated with an advanced PH phenotype. Methods Open-label, prospective analysis of patients with PF-PH referred for lung transplantation (LT). Advanced PH was defined as mean pulmonary artery pressure (mPAP) =35 mm Hg. We compared haemodynamics, Doppler echocardiography (DE), oxygenation, dyspnoea and quality of life indices, and 6 min walk distance (6MWD) before and 12 weeks after parenteral treprostinil. Results 15 patients were recruited in the study. After therapy, there were significant improvements in right heart haemodynamics (right atrial pressure (9.5 ± 3.4 vs 6.0 ± 3.7); mPAP (47 ± 8 vs 38.9 ± 13.4); CI (2.3 ± 0.5 vs 2.7 ± 0.6); pulmonary vascular resistance (698 ± 278 vs 496 ± 229); transpulmonary gradient (34.7 ± 8.7 vs 28.5 ± 10.3); mvO2 (65 ± 7.2 vs 70.9 ± 7.4); and stroke volume index (29.2 ± 6.7 vs 33 ± 7.3)) and DE parameters reflecting right heart function (right ventricular (RV) end diastolic area (36.4 ± 5.2 vs 30.9 ± 8.2 cm2), left ventricular eccentricity index (1.7 ± 0.6 vs 1.3 ± 0.5), tricuspid annular planar systolic excursion (1.6 ± 0.5 vs 1.9 ± 0.2 cm)). These changes occurred without significant alteration in systemic oxygenation, heart rate, or mean systemic arterial pressure. In addition, improvements were seen in 6MWD (171 ± 93 vs 230 ± 114), 36-Item Short Form Health Survey Mental Component Summary aggregate (38 ± 11 vs 44.2 ± 10.7), University of California, San Diego Shortness of Breath Questionnaire (87 ± 17.1 vs 73.1 ± 21), and brain natriuretic peptide (558 ± 859 vs 228 ± 340). Conclusions PH-targeted therapy may improve right heart haemodynamics and echocardiographic function without affecting systemic oxygen saturation in an advanced PH phenotype associated with RV dysfunction in the setting of PF.

Objective Pulmonary arterial hypertension (PAH) affects up to 15% of patients with connective tissue diseases (CTDs). Previous recommendations developed as part of larger efforts in PAH did not include detailed recommendations for patients with CTD-associated PAH. Therefore, we sought to develop recommendations for screening and early detection of CTD-associated PAH. Methods We performed a systematic review of the literature on the screening and diagnosis of PAH in CTD. Using the RAND/University of California, Los Angeles consensus methodology, we developed case scenarios followed by 2 stages of voting. First, international experts from a variety of specialties voted anonymously on the appropriateness of each case scenario. The experts then met face-to-face to discuss and resolve discrepant votes to arrive at consensus recommendations. Results The key recommendation stated that all patients with systemic sclerosis (SSc) should be screened for PAH. In addition, patients with mixed connective tissue disease or other CTDs with scleroderma features (scleroderma spectrum disorders) should be screened for PAH. It was recommended that screening pulmonary function tests (PFTs) with single-breath diffusing capacity for carbon monoxide, transthoracic echocardiogram, and measurement of N-terminal pro-brain natriuretic peptide (NT-proBNP) be performed in all patients with SSc and scleroderma spectrum disorders. In patients with SSc and scleroderma spectrum disorders, transthoracic echocardiogram and PFTs should be performed annually. The full screening panel (transthoracic echocardiogram, PFTs, and measurement of NT-proBNP) should be performed as soon as any new signs or symptoms are present. Conclusion We provide consensus-based, evidence-driven recommendations for screening and early detection of CTD-associated PAH. It is our hope that these recommendations will lead to earlier detection of CTD-associated PAH and ultimately improve patient outcomes. [ABSTRACT FROM AUTHOR]

Objective The 1980 American College of Rheumatology (ACR) classification criteria for systemic sclerosis (SSc) lack sensitivity for early SSc and limited cutaneous SSc. The present work, by a joint committee of the ACR and the European League Against Rheumatism (EULAR), was undertaken for the purpose of developing new classification criteria for SSc. Methods Using consensus methods, 23 candidate items were arranged in a multicriteria additive point system with a threshold to classify cases as SSc. The classification system was reduced by clustering items and simplifying weights. The system was tested by 1) determining specificity and sensitivity in SSc cases and controls with scleroderma-like disorders, and 2) validating against the combined view of a group of experts on a set of cases with or without SSc. Results It was determined that skin thickening of the fingers extending proximal to the metacarpophalangeal joints is sufficient for the patient to be classified as having SSc; if that is not present, 7 additive items apply, with varying weights for each: skin thickening of the fingers, fingertip lesions, telangiectasia, abnormal nailfold capillaries, interstitial lung disease or pulmonary arterial hypertension, Raynaud's phenomenon, and SSc-related autoantibodies. Sensitivity and specificity in the validation sample were, respectively, 0.91 and 0.92 for the new classification criteria and 0.75 and 0.72 for the 1980 ACR classification criteria. All selected cases were classified in accordance with consensus-based expert opinion. All cases classified as SSc according to the 1980 ACR criteria were classified as SSc with the new criteria, and several additional cases were now considered to be SSc. Conclusion The ACR/EULAR classification criteria for SSc performed better than the 1980 ACR criteria for SSc and should allow for more patients to be classified correctly as having the disease.

Objectives The cytokine oncostatin M (OSM) is implicated in the pathology of SSc. Inhibiting OSM signalling using GSK2330811 (an anti-OSM monoclonal antibody) in patients with SSc has the potential to slow or stop the disease process. Methods This multicentre, randomized, double-blind, placebo-controlled study enrolled participants ≥18 years of age with active dcSSc. Participants were randomized 3:1 (GSK2330811:placebo) in one of two sequential cohorts to receive GSK2330811 (cohort 1: 100 mg; cohort 2: 300 mg) or placebo s.c. every other week for 12 weeks. The primary endpoint was safety; blood and skin biopsy samples were collected to explore mechanistic effects on inflammation and fibrosis. Clinical efficacy was an exploratory endpoint. Results Thirty-five participants were randomized to placebo (n  = 8), GSK2330811 100 mg (n  = 3) or GSK2330811 300 mg (n  = 24). Proof of mechanism, measured by coordinate effects on biomarkers of inflammation or fibrosis, was not demonstrated following GSK2330811 treatment. There were no meaningful differences between GSK2330811 and placebo for any efficacy endpoints. The safety and tolerability of GSK2330811 were not favourable in the 300 mg group, with on-target, dose-dependent adverse events related to decreases in haemoglobin and platelet count that were not observed in the 100 mg or placebo groups. Conclusion Despite a robust and novel experimental medicine approach and evidence of target engagement, anticipated SSc-related biologic effects of GSK2330811 were not different from placebo and safety was unfavourable, suggesting OSM inhibition may not be a useful therapeutic strategy in SSc.

Objective: The National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) roadmap initiative is a cooperative group program of research designed to develop, evaluate, and standardize item banks to measure patient-reported outcomes relevant across medical conditions. The objective of the current study was to assess feasibility and evaluation of the construct validity of PROMIS item banks versus legacy measures in an observational study in systemic sclerosis (SSc). We hypothesized that the PROMIS item banks can be administered in a clinical setting if there is adequate staff support without disrupting the flow of clinic.Methods: Patients with SSc in a single academic center completed computerized adaptive test (CAT) administered PROMIS item banks during the clinic visit and legacy measures (using paper and pencil). The construct validity of PROMIS items was evaluated by examining correlations with corresponding legacy measures using multitrait-multimethod analysis.Results: Participants consisted of 143 SSc patients with an average age of 51.5 years; 71% were female and 68% were white. The average number of items completed for each CAT-administered item bank ranged from 5 to 8 (69 CAT items per patient), and the average time to complete each CAT-administered item bank ranged from 48 seconds to 1.9 minutes per patient (average time = 11.9 minutes/per patient for 11 banks). All correlations between PROMIS domains and respective legacy measures were large and in the hypothesized direction (ranged from 0.61 to 0.82).Conclusion: Our study supports the construct validity of the CAT-administered PROMIS item banks and shows that they can be administered successfully in a clinic with support staff. Future studies should assess the feasibility of PROMIS item banks in a busy clinical practice. [ABSTRACT FROM AUTHOR]

Abstract: T cells, particularly those producing IL-4, are implicated in inflammation-mediated fibrosis. In our phase I/IIa open-label pilot study in 15 patients with scleroderma-interstitial lung disease (SSc-ILD), high-dose imatinib treatment showed modest improvement in lung function and skin score, but with several adverse events. Here, we investigated T cell phenotype and cytokine production in bronchoalveolar lavage (BAL) from patients enrolled in this trial. We found that IL-4+ T cells showed a stronger correlation with ground glass opacity (GGO) than fibrosis scores on lung high-resolution computer tomography scans. Frequencies of IL-4+ T cells also discriminated patients with high (≥20) versus low (<20) GGO scores. Functional annotation clustering of proteins that correlated with T cells identified two major clusters that belonged to immune/inflammatory and wounding response. Repeat analyses after 1year of treatment in 10 BAL samples, one each from the right middle and lower lobes of lung from 5 patients, showed that post-imatinib, IL-4+ T cells were profoundly reduced but CD4+ T cells increased, except in one patient who showed worsening of SSc-ILD. Post-imatinib increase in CD4+ T cells correlated with soluble ICAM-3 and PECAM-1 levels in BAL, which associated with the lack of worsening in SSc-ILD. Thus, imatinib might confer its therapeutic effect in fibrosis via re-directing T cell responses from type 2 to other, non-type 2 cytokine producing CD4+ T cells. [Copyright &y& Elsevier]

Objective Patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) are thought to have the greatest decline in lung function (forced vital capacity [FVC] % predicted) in the early years after disease onset. The aim of this study was to assess the natural history of the decline in FVC % predicted in patients receiving placebo in the Scleroderma Lung Study and to evaluate possible factors for cohort enrichment in future therapeutic trials. Methods Patients randomized to receive placebo (n = 79) were divided into 3 groups based on the duration of SSc (0-2 years, 2-4 years, and >4 years). Descriptive statistics and a mixed-effects model were used to analyze the rate of decline in the FVC % predicted over a 1-year period. Additional analyses stratified according to the severity of fibrosis on high-resolution computed tomography (HRCT) were performed, and interactions between disease severity and disease duration were explored. Results The mean ± SD decline in the unadjusted FVC % predicted during the 1-year period was 4.2 ± 12.8%. At baseline, 28.5%, 43.0%, and 28.5% of patients were in the groups with disease durations of 0-2 years, 2-4 years, and >4 years, respectively. The rate of decline in the FVC % predicted was not significantly different across the 3 disease groups ( P = 0.85). When stratified by baseline fibrosis on HRCT, the rate of decline in the FVC % predicted was statistically significantly greater in the group with severe fibrosis (mean annualized decline in the FVC % predicted 7.2% versus 2.7% in the groups with no or moderate fibrosis; P = 0.008). The decline observed in the group with severe fibrosis was most pronounced in those with a relatively short disease duration (0-2 years; annualized decline 7.0%). Conclusion Among patients with SSc-ILD in the Scleroderma Lung Study, the rates of progression of lung disease were similar irrespective of disease duration. The baseline HRCT fibrosis score is a predictor of a future decline in the FVC % predicted in the absence of effective treatment. [ABSTRACT FROM AUTHOR]

The article presents a reprint of the article "Scleroderma and Fibrosing Disorders: Advances in Management," by Simon Glen, which appeared in the 2010 issue of the International Journal of Advances in Rheumatology. It focuses on the advancement in managing scleroderma, also known as systemic sclerosis (SSc), an autoimmune rheumatological disorder that causes inflammation, vascular damage, and fibrosis. On the hand, it discusses the main differences between a limited and diffuse SSC.

Background: Arthritis is the leading cause of disability in the United States. We assess the generic health-related quality-of-life (HRQOL) among a nationally representative sample of US adults with and without self-reported arthritis. Methods: The NHMS, a cross-sectional survey of 3,844 adults (35-89 years) administered EuroQol-5D (EQ-5D), Health Utilities Index Mark 2 (HUI2) and 3 (HUI3), SF-36v2™, Quality of Well-being Scale self-administered form (QWB-SA), and the Health and Activities Limitations index (HALex) to each respondent via a telephone interview. Weighted multiple linear regression was used to generate age-gender-arthritis-stratified unadjusted HRQOL means and means adjusted for sociodemographic, socioeconomic covariates and comorbidities by arthritis-age category. Results: The estimated population prevalence of self-reported arthritis was 31%. People with arthritis were more likely to be woman, older, of lower socioeconomic status, and had more self-reported comorbidities than were those not reporting arthritis. Adults with arthritis had lower HRQOL on six different indexes compared with adults without arthritis, with overall differences ranging from 0.03 (QWB-SA, age-group 65-74) to 0.17 (HUI3, age-group 35-44; all P-value < .05). Conclusion: Arthritis in adults is associated with poorer HRQOL. We provide age-related reference values for six generic HRQOL measures in people with arthritis. [ABSTRACT FROM AUTHOR]

Objective. The Gout Impact Scale (GIS) is a gout-specific quality of life instrument that assesses impact of gout during an attack and impact of overall gout. The GIS has five scales and each is scored from 0 to 100 (worse health). Our objective was to assess minimally important differences (MIDs) for the GIS administered in a randomized controlled trial (RCT) assessing rilonacept vs placebo for prevention of gout flares during initiation of allopurinol therapy.Methods. Trial subjects ( n = 83) included those with two or more gout flares (self-reported) in the past year. Of these, 73 had data for Weeks 8 vs 4 and formed the MID analysis group and were analysed irrespective of the treatment assignment. Subjects completed the GIS and seven patient-reported anchors. Subjects with a one-step change (e.g. from very poor to poor) were considered as the MID group for each anchor. The mean change in GIS scores and effect size (ES) was calculated for each anchor’s MID group. The average of these created the overall summary MID statistics for each GIS. An ES of 0.2–0.5 was considered to represent MID estimates.Results. Trial subjects (n = 73) were males (96.0%), White (90.4%), with mean age of 50.5 years and serum uric acid of 9.0 mg/dl. The mean change score for the MID improvement group for scales ranged from −5.24 to −7.61 (0–100 scale). The ES for the MID improvement group for the four scales ranged from 0.22 to 0.38.Conclusion. The MID estimates for GIS scales are between 5 and 8 points (0–100 scale). This information can aid in interpreting the GIS results in future gout RCTs.Trial Registration.

We describe a framework to help clinicians think about health-related quality of life in their gastrointestinal (GI) patients. We introduce 'GI distress' as a clinically relevant concept and explain how it may result from physical symptoms, cognitions, and emotions. The GI distress framework suggests that providers should divide GI physical symptoms into four categories: pain, gas/bloat, altered defecation, and foregut symptoms. We describe how these physical symptoms can be amplified by maladaptive cognitions, including external locus of control, catastrophizing, and anticipation anxiety. We suggest determining the level of embarrassment from GI symptoms and asking about stigmatization. GI patients may also harbor emotional distress from their illness and may exhibit visceral anxiety marked by hypervigilance, fear, and avoidance of GI sensations. Look for signs of devitalization, indicated by inappropriate fatigue. When appropriate, screen for suicidal ideations. Finally, we provide a list of high-yield questions to screen for these maladaptive cognitions and emotions, and explain how the GI distress framework can be used in clinical practice.

The findings of the study are discussed in detail.

OBJECTIVE: To investigate the familiality of systemic sclerosis (SSc) in relation to Raynaud's phenomenon (RP) (a marker of vasculopathy), other autoimmune inflammatory disease, and fibrotic interstitial lung disease (ILD). METHODS: A genealogic resource, the Utah Population Database (UPDB), was used to test heritability of RP, other autoimmune disease, and ILD. Diseases were defined by International Classification of Diseases, Ninth Revision codes and identified from statewide discharge data, the University of Utah Health Science Center Enterprise Data Warehouse, and death certificates and were linked to the UPDB for analysis. Familial standardized incidence ratio (FSIR), relative risks (RRs) to first-, second-, third-, and fourth-degree relatives for SSc, RP, other autoimmune disease, and ILD (with 95% confidence intervals [95% CIs]), and population attributable risk (PAR) were calculated. RESULTS: A software kinship analysis tool was used to analyze 1,037 unique SSc patients. Fifty SSc families had significant FSIRs, ranging from 2.07 to 17.60. The adjusted PAR was approximately 8%. The RRs were significant for other autoimmune disease in the first-degree relatives (2.49 [95% CI 1.99-3.41], P = 2.42 x 10(-15)) and second-degree relatives (1.48 [95% CI 1.34-2.39], P = 0.002), for RP in first-degree relatives (6.38 [95% CI 3.44-11.83], P = 4.04 x 10(-9)) and second-degree relatives (2.39 [95% CI 1.21-4.74], P = 0.012), and for ILD in first-degree relatives (1.53 [95% CI 1.04-2.26], P = 0.03), third-degree relatives (1.47 [95% CI 1.18-1.82], P = 0.0004), and fourth-degree relatives (1.2 [95% CI 1.06-1.35], P = 0.004). CONCLUSION: These data suggest that SSc pedigrees include more RP, autoimmune inflammatory disease, and ILD than would be expected by chance. In SSc pedigrees, genetic predisposition to vasculopathy is the most frequent risk among first-degree relatives. [ABSTRACT FROM AUTHOR]

Objective: 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. Methods: 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. Results: 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. Conclusion: 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. [ABSTRACT FROM AUTHOR]

The article presents a study on the efficacy of rapamycin in diffuse systemic sclerosis (SSc) treatment. It is stated in the study that rapamycin blocks T cell response to cytokines, especially interleukin-2. It notes that the study evaluated the potential efficacy of rapamycin or methotrexate (MTX) using the modified Rodnan skin thickness score (MRSS) and the Health Assessment Questionnaire. It also mentions that the study found that the MRSS improved significantly after drug administration.

The article discusses the potentials of recombinant human relaxin in treating systemic sclerosis (SSc) with diffuse cutaneous involvement. It utilizes large randomized, double-blind, placebo controlled trial. Renovascular systems of patients with SSc are sensitive to changes in blood flow and other stimuli. It shows that recombinant human relaxin with subcutaneous (SC) infusion over 24 weeks is not better than placebo in improving the skin score and pulmonary conditions in patients.

Gout is a chronic painful inflammatory arthritis. Data regarding the impact of gout on health-related quality of life, however, are limited. We interviewed patients with chronic stable gout. Health status was measured by using the Short Form 36 (SF-36) physical component summary (PCS) and physical component summary (MCS) and the Health Assessment Questionnaire-Disability Index (HAQ-DI). Direct preference-based measures included a health rating scale (RS), the time tradeoff (TTO), and standard gamble (SG) for one’s current health state with gout and current health state without gout; indirect preference-based measures included the SF-6D and the EQ-5D. Disutilities for gout were assessed by subtracting preference scores for current health states with gout from those for current health without gout and were compared between patients ranking gout as their top health concern versus the rest of the patients. Of the 80 interviewees, 72 (90%) were male, 55 (69%) were Caucasian, and the mean (SD) age was 60 (11) years. The mean SF-36 PCS and MCS scores were 38.9 and 48.6, respectively. The mean (SD) SF-6D score was 0.68 (0.13) and the mean (SD) EQ-5D score was 0.73 (0.23). The mean (SD) RS disutility for gout was 0.05 (0.12), the mean TTO disutility was 0.03 (0.12), and the mean SG disutility was 0.02 (0.11). The RS disutilities of subject patients who ranked gout as their top concern ( n = 17) trended towards being statistically significantly larger than those of the remaining patients, P = 0.06 but their TTO and SG disutilities were similar to those of the remaining patients. Although physical functioning of patients with gout is often compromised, patients with chronic stable gout do not assign a large disutility to gout per se. Still, patients who rank their gout as their top health concern tend to assign greater RS disutility to gout than do other patients. [ABSTRACT FROM AUTHOR]

Objective: Systemic sclerosis, primary pulmonary hypertension, and sickle cell disease are uncommon vasculopathic diseases affecting women. We estimated the nationwide occurrence of pregnancies in women with these conditions and compared pregnancy outcomes to the general obstetric population.Methods: We studied the 2002-2004 Nationwide Inpatient Sample, of the Healthcare Cost and Utilization Project to estimate the number of obstetric hospitalizations and deliveries among women with systemic sclerosis, primary pulmonary hypertension, sickle cell disease, and women in the general population. Pregnancy outcomes included length of hospital stay, hypertensive disorders including preeclampsia, intrauterine growth restriction (IUGR), and cesarean delivery. Multivariable regression analyses were performed using maternal age, race or ethnicity, antiphospholipid antibody syndrome, diabetes mellitus, and renal failure as covariates.Results: Of an estimated 11.2 million deliveries, 504 occurred in women with systemic sclerosis, 182 with primary pulmonary hypertension, and 4,352 with sickle cell disease. Systemic sclerosis, was associated with an increased risk of hypertensive disorders including preeclampsia (odds ratio [OR] 3.71, 95% confidence interval [CI] 2.25-6.15), IUGR (OR 3.74, 95% CI 1.51-9.28), and increased length of hospital stay. Primary pulmonary hypertension was associated with an increase in the odds of antenatal hospitalization (OR 4.67, 95% CI 2.88-7.57), hypertensive disorders including preeclampsia (OR 5.62, 95% CI 2.60-12.15) and a substantial increase in length of hospital stay. Sickle cell disease was associated with an increased odds of antenatal hospitalization (OR 5.56 95% CI 5.08-6.09), hypertensive disorders including preeclampsia (OR 1.78, 95% CI 1.48-2.14), and IUGR (OR 2.91, 95% CI 2.16-3.93), with a modest increase in length of hospital stay.Conclusion: Women with systemic sclerosis, primary pulmonary hypertension, and sickle cell disease have significantly increased rates of adverse pregnancy outcomes, requiring extensive preconceptional counseling about the risks of pregnancy.

RA is aggravated when there are inflammatory cytokines called tumor necrosis factor α (TNF α). It was found that psychological stress does trigger the production of the said cytokine which worsens RA.

Objectives: To evaluate the reliability and validity and estimate the minimally important difference (MID) for the SF-6D in patients with systemic sclerosis (SSc). Subjects We used data from two clinical studies to analyze the SF-6D in patients with SSc: Study 1 was a cross-sectional observational study (N = 107) designed to assess three direct preference measures--the rating scale, time trade-off, and standard gamble (SG) in patients with diffuse SSc and limited SSc, and Study 2 was a 12-month randomized, placebo-controlled, clinical trial (N = 168) assessing oral bovine collagen versus placebo in diffuse SSc.Methods: We assessed the test-retest reliability of the SF-6D in Study 2 over a mean (SD) 4.8 (3.0)-week interval and the agreement between the SF-6D and direct preference measures in Study 1 using intraclass correlations (ICC). The MID was estimated using three different anchors--the SF-36 change in health item (patients who answered "somewhat better" formed the MID group), the Health Assessment Questionnaire-Disability Index (HAQ-DI; change of > or =0.14 and > or =0.22) and the skin score (change of > or =5.3). Results The mean (SD) SF-6D scores were 0.61 (0.12) in Study 1 and 0.64 (0.13) in Study 2. Test-retest reliability for the SF-6D was high (ICC = 0.82 [95% CI: 0.76, 0.87]). Agreement between the SF-6D and three direct preferences measures was poor to moderate (0.16-0.52). The MID estimate for the SF-6D using the change in SF-36 item -0.012 and this level of change was similar to the no change group. The mean MID estimate for the SF-6D improvement using the HAQ-DI and skin score as anchors was 0.035 (effect size of 0.27).Conclusion: This is the first study to assess the SF-6D in SSc. The SF-6D is reliable and valid in patients with SSc. We provide MID estimates that can aid in calculating sample size for clinical trials involving patients with diffuse SSc. [ABSTRACT FROM AUTHOR]
