The aim was to update the 2009 European League against Rheumatism (EULAR) recommendations for the treatment of systemic sclerosis (SSc), with attention to new therapeutic questions. Update of the previous treatment recommendations was performed according to EULAR standard operating procedures. The task force consisted of 32 SSc clinical experts from Europe and the USA, 2 patients nominated by the pan-European patient association for SSc (Federation of European Scleroderma Associations (FESCA)), a clinical epidemiologist and 2 research fellows. All centres from the EULAR Scleroderma Trials and Research group were invited to submit and select clinical questions concerning SSc treatment using a Delphi approach. Accordingly, 46 clinical questions addressing 26 different interventions were selected for systematic literature review. The new recommendations were based on the available evidence and developed in a consensus meeting with clinical experts and patients. The procedure resulted in 16 recommendations being developed (instead of 14 in 2009) that address treatment of several SSc-related organ complications: Raynaud's phenomenon (RP), digital ulcers (DUs), pulmonary arterial hypertension (PAH), skin and lung disease, scleroderma renal crisis and gastrointestinal involvement. Compared with the 2009 recommendations, the 2016 recommendations include phosphodiesterase type 5 (PDE-5) inhibitors for the treatment of SSc-related RP and DUs, riociguat, new aspects for endothelin receptor antagonists, prostacyclin analogues and PDE-5 inhibitors for SSc-related PAH. New recommendations regarding the use of fluoxetine for SSc-related RP and haematopoietic stem cell transplantation for selected patients with rapidly progressive SSc were also added. In addition, several comments regarding other treatments addressed in clinical questions and suggestions for the SSc research agenda were formulated. These updated data-derived and consensus-derived recommendations will help rheumatologists to manage patients with SSc in an evidence-based way. These recommendations also give directions for future clinical research in SSc., Competing Interests: Competing interests: OK-B: consultancies or speakers bureau: AbbVie, Actelion, Bayer, Inventiva, Pfizer, Roche; JA: grant/research support from BMS, Pfizer, Roche/Chugai, Sanofi-Aventis, Actelion; MB: consultant for Actelion; YA: consultant for: Bayer Pharmaceuticals, Actelion, Pfizer, Inventiva, Medac, Servier, Boehringer Ingelheim, Sanofi-Aventis, CSL Behring, Roche; OD: consultant for: 4D Science, Actelion, Active Biotec, Bayer-Schering, Biogen, Biovitrium, BMS, Boehringer Ingelheim Pharma, EpiPharm, Ergonex, GSK, Inventiva, Medac, Novartis, Pfizer, Pharmacyclics, Roche/Genentech, Sanofi/Genzyme, Serodapharm, Sinoxa and United BioSource Corporation; MC: Mundipharm, Actelion, BMS, Horizon, Pfizer, Biogen, Celltrion, Cellgene; LC: consultant for Actelion and Pfizer; CPD: consulting fees from Roche, Actelion, GSK, Bayer Pharmaceuticals; IF: constultant: Bayer, Roche/Chugai; MF: Actelion; DEF: grant/research support from AbbVie, Actelion, Amgen, BMS, NIH, Novartis, Pfizer, Roche/Genentech and consultancy with AbbVie, Actelion, Amgen, BMS, Cytori, Novartis, Pfizer, Roche/Genentech; NH: lecture fees from Actelion, Bayer, Roche; DK: consultancy with Actelion, BMS, Bayer, Covis, Cytori, Genentech/Roche, Gilead, Sanofi-Aventis and grant from NIH/NIAID, NIH/NIAMS, Bayer and BMS; ALH: consultant/speaker/research funding: Actelion, consultant: Apricus; JMvL: honoraria from MSD, BMS, Pfizer, Eli Lilly, Roche; GR: lecturers fees from Bayer, Pfizer, Novartis, Actelion, GSK, BMS and research grants from Actelion; RS: consultant for: Entelligence Program, supported by Actelion; inPractice Rheumatology, grant support: BMS, Bayer; AS: research grant from Actelion; IT: Actelion; UM-L: grant/research support from: EULAR grant, consultant for: Actelion, GSK, Bayer, Medac, Roche/Chugai., (Published by the BMJ Publishing Group Limited.

Objectives: PHAROS registry is a prospective longitudinal cohort study to understand the natural history of pulmonary hypertension (PH) in systemic sclerosis (SSc)., Methods: "At-risk" pulmonary arterial hypertension (PAH) is defined by these entry criteria: echocardiogram (echo) systolic pulmonary arterial pressure (sPAP) >40 mmHg, diffusion lung capacity of carbon monoxide (DLco) <55% predicted, or ratio of percentage forced vital capacity (FVC)/percentage DLco >1.6, as measured by pulmonary function testing (PFT). Patients were followed up annually and right heart catheterization (RHC) performed if PH was suspected. We used descriptive statistics and Kaplan-Meier estimate of time to PH diagnosis., Results: A total of 251 "at-risk" subjects were enrolled between 2005 and 2012 and followed up for mean of 2.5 ± 1.2 years. The mean age at entry was 56.7 ± 11.0 and disease duration was 9.9 ± 8.7 years. Overall, 82 patients had RHC, and 35 were confirmed to have new PH. There were no differences in age, gender, SSc subtypes, antibodies, and disease duration between the "at-risk" and new PH groups. Using Kaplan-Meier survival, the time to PH was 10% at 2 years, 13% at 3 years, and 25% at 5 years. Most new PH patients at entry met the PFT criteria (76%), had significantly higher sPAP (p = 0.013), had shorter 6-min walk distance, and had exercise-induced hypoxia (p = 0.003) than "at-risk" PAH group., Conclusions: A low DLco, high FVC/DLco, exercise-induced hypoxia and entry echo sPAP > 40 were strongly associated with future PH, though RHC was necessary to confirm PH. This ongoing prospective study confirms that these high-risk factors do predict future PH., (Copyright © 2014 Elsevier Inc. All rights reserved.)

African Americans (AA) with systemic sclerosis (SSc) have a worse prognosis compared to Americans of European descent (EA). We conducted the current study to test the hypothesis that AA patients with SSc have more severe disease and poorer outcomes compared to EA patients when afflicted with pulmonary arterial hypertension (PAH). We studied 160 consecutive SSc patients with PAH diagnosed by right heart catheterization, comparing demographics, hemodynamics, and outcomes between AA and EA patients. The cohort included 29 AA and 131 EA patients with similar baseline characteristics except for increased prevalence of diffuse SSc in AA. AA patients had worse functional class (FC) (80% FC III-IV vs 53%; p = 0.02), higher brain natriuretic peptide (NT-pro-BNP) (5729 ± 9730 pg/mL vs 1892 ± 2417 pg/mL; p = 0.02), more depressed right ventricular function, a trend toward lower 6-minute walk distance (263 ± 111  m vs 333 ± 110  m; p = 0.07), and worse hemodynamics (cardiac index 1.95 ± 0.58 L/min/m vs 2.62 ± 0.80 L/min/m; pulmonary vascular resistance 10.3 ± 6.2 WU vs 7.6 ± 5.0 WU; p  < 0.05) compared with EA patients. Kaplan-Meier survival estimates for AA and EA patients, respectively, were 62% vs 73% at 2 years and 26% vs 44% at 5 years (p  > 0.05). In conclusion, AA patients with SSc-PAH are more likely to have diffuse SSc and to present with significantly more severe PAH compared with EA patients. AA patients also appear to have poorer survival, though larger studies are needed to investigate this association definitively.

Background: Gene expression profiling of peripheral blood mononuclear cells (PBMCs) is a powerful tool for the identification of surrogate markers involved in disease processes. The hypothesis tested in this study was that chronic exposure of PBMCs to a hypertensive environment in remodeled pulmonary vessels would be reflected by specific transcriptional changes in these cells., Methodology/principal Findings: The transcript profiles of PBMCs from 30 idiopathic pulmonary arterial hypertension patients (IPAH), 19 patients with systemic sclerosis without pulmonary hypertension (SSc), 42 scleroderma-associated pulmonary arterial hypertensio patients (SSc-PAH), and 8 patients with SSc complicated by interstitial lung disease and pulmonary hypertension (SSc-PH-ILD) were compared to the gene expression profiles of PBMCs from 41 healthy individuals. Multiple gene expression signatures were identified which could distinguish various disease groups from controls. One of these signatures, specific for erythrocyte maturation, is enriched specifically in patients with PH. This association was validated in multiple published datasets. The erythropoiesis signature was strongly correlated with hemodynamic measures of increasing disease severity in IPAH patients. No significant correlation of the same type was noted for SSc-PAH patients, this despite a clear signature enrichment within this group overall. These findings suggest an association of the erythropoiesis signature in PBMCs from patients with PH with a variable presentation among different subtypes of disease., Conclusions/significance: In PH, the expansion of immature red blood cell precursors may constitute a response to the increasingly hypoxic conditions prevalent in this syndrome. A correlation of this erythrocyte signature with more severe hypertension cases may provide an important biomarker of disease progression.

N-terminal pro-brain natriuretic peptide (NT-proBNP) is a marker of neurohormonal activation that is useful in the diagnosis and prognosis of various forms of pulmonary arterial hypertension (PAH). We sought to characterise and compare NT-proBNP in a cohort of PAH related to systemic sclerosis (PAH-SSc) and idiopathic PAH (IPAH) patients. NT-proBNP levels, collected from PAH-SSc and IPAH patients followed prospectively, were compared and correlated with haemodynamic variables. Cox proportional hazard models were created to assess the predictive value of NT-proBNP. 98 patients (55 PAH-SSc, 43 IPAH) were included. Haemodynamics were similar, except for lower mean pulmonary arterial pressure in PAH-SSc. NT-proBNP levels were significantly higher in PAH-SSc (3,419+/-3,784 versus 1,393+/-1,633 pg x mL(-1); p<0.01) and were more closely related to haemodynamics in PAH-SSc than IPAH. 28 patients died. NT-proBNP predicted survival (hazard ratio (HR) 3.18; p<0.01) in the overall cohort; however, when stratified by group, predicted survival only in PAH-SSc (HR 3.07, p<0.01 versus 2.02, p = 0.29 in IPAH). This is the first description showing NT-proBNP levels are 1) significantly higher in PAH-SSc than IPAH despite less severe haemodynamic perturbations, and 2) stronger predictors of survival in PAH-SSc, suggesting that neurohormonal regulation may differ between PAH-SSc and IPAH. Future studies to define pertinent mechanisms are warranted.

Study Objectives: To determine whether primary pulmonary hypertension (PPH) is associated with scleroderma-like changes in nailfold capillaries., Design: Blinded, prospective, case-control study., Setting: University medical centers in Baltimore, MD., Patients: Thirty-seven patients with PPH, 15 patients with scleroderma, and 13 healthy control subjects., Measurements: Subjects underwent nailfold capillary videomicroscopy of the fourth digits of both hands. Capillary images were evaluated by two blinded, trained graders according to standardized criteria for the presence of scleroderma nailfold changes., Results: The prevalence of scleroderma-associated nailfold changes in patients with PPH (1 of 37 patients) was dramatically lower than that in patients with scleroderma (9 of 15 patients; p < 0.0001). The distribution of nailfold grades for the PPH patients was indistinguishable from that of the healthy control subjects., Conclusion: PPH is not associated with scleroderma-like vasculopathy of nailfold capillaries.

Background: Pulmonary hypertension is a progressive and often fatal complication of the scleroderma spectrum of disease for which no treatment has been proven effective in a randomized trial., Objective: To determine the effect of epoprostenol on pulmonary hypertension secondary to the scleroderma spectrum of disease., Design: Randomized, open-label, controlled trial., Setting: 17 pulmonary hypertension referral centers., Patients: 111 patients with moderate to severe pulmonary hypertension., Intervention: Epoprostenol plus conventional therapy or conventional therapy alone., Measurements: The primary outcome measure was exercise capacity. Other measures were cardiopulmonary hemodynamics, signs and symptoms of pulmonary hypertension and scleroderma, and survival., Results: Exercise capacity improved with epoprostenol (median distance walked in 6 minutes, 316 m at 12 weeks compared with 270 m at baseline) but decreased with conventional therapy (192 m at 12 weeks compared with 240 m at baseline). The difference between treatment groups in the median distance walked at week 12 was 108 m (95% CI, 55.2 m to 180.0 m) (P < 0.001). Hemodynamics improved at 12 weeks with epoprostenol. The changes in mean pulmonary artery pressure for the epoprostenol and conventional therapy groups were -5.0 and 0.9 mm Hg, respectively (difference, -6.0 mm Hg [CI, -9.0 to -3.0 mm Hg), and the mean changes in pulmonary vascular resistance were -4.6 and 0.9 mm Hg/L per minute, respectively (difference, -5.5 mm Hg/L per minute [CI, -7.3 to -3.7 mm Hg/L per minute). Twenty-one patients treated with epoprostenol and no patients receiving conventional therapy showed improved New York Heart Association functional class. Borg Dyspnea Scores and Dyspnea-Fatigue Ratings improved in the epoprostenol group. Trends toward greater improvement in severity of the Raynaud phenomenon and fewer new digital ulcers were seen in the epoprostenol group. Four patients in the epoprostenol group and five in the conventional therapy group died (P value not significant). Side effects of epoprostenol therapy included jaw pain, nausea, and anorexia. Adverse events related to the epoprostenol delivery system included sepsis, cellulitis, hemorrhage, and pneumothorax (4% incidence for each condition)., Conclusions: Continuous epoprostenol therapy improves exercise capacity and cardiopulmonary hemodynamics in patients with pulmonary hypertension due to the scleroderma spectrum of disease.

Longitudinal studies of large cohorts of patients with Raynaud's Phenomenon have addressed the predictors of developing a secondary disease. New insights have been reported into the pathogenesis of Raynaud's phenomenon and the consequences of ischemia. Studies have suggested that more than one defect may cause Raynaud's phenomenon, including increased alpha-2 sympathetic receptor activity on vessels, endothelial dysfunction, deficiency of calcitonin gene related peptide protein--containing nerves or some central thermoregulatory defect. The vasoconstricting and profibrotic cytokine endothelin-1 was found to be elevated in scleroderma but did not correlate with disease subset or with evidence of pulmonary hypertension. Oxidant stress is thought to be increased in scleroderma, causing tissue damage and provoking fibrosis. Treatment with infusion of prostacyclin for primary pulmonary hypertension was approved, paving the way for studies of secondary forms of pulmonary hypertension. Oral prostanoids are being tested for the treatment of Raynaud's phenomenon.

Purpose: Patients with systemic sclerosis (SSc) do not exhibit a normal increase in the diffusing capacity for carbon monoxide (DLCO) on assuming the supine position. We sought to determine whether a potent prostacyclin derivative and vasodilator, iloprost, would reverse this defect., Patients and Methods: Fourteen patients with SSc were enrolled in a randomized, double-blind, placebo-controlled study of iloprost. Patients were tested before and during 3 days of iloprost or placebo infusion with both upright and supine pulmonary function studies., Results: The results of baseline pulmonary function studies including DLCO were not significantly altered by iloprost. Furthermore, iloprost did not alter the abnormal postural DLCO response., Conclusion: These results suggest that the pulmonary vascular defects seen in this group of patients are not a consequence of reversible pulmonary vasospasm.
