Abstract
The aim of the study was to evaluate the adherence of systemic sclerosis (SSc) female patients to cervix and breast cancer screening procedures, as suggested by local guidelines. A cohort of 84 SSc women was asked if they had undergone mammography and Pap test during the previous 2- and 3-year intervals, as indicated according to the Italian recommendations. The results were compared with those collected in patients affected by other chronic rheumatic disorders and in the general population. More than 85% of SSc women declared to comply with an age-related cervix and breast cancer screening schedule. The data were similar to those collected in patients affected by other chronic rheumatic disorders, whereas the subjects belonging to the general population reported to undergo breast cancer screening more frequently. Among SSc women, neither the educational level, nor the lung and skin involvement influenced their cancer screening program compliance. Only a positive history of ischemic digital ulcers seemed to interfere with mammography. Our study reported a very high percentage of SSc female patients who adhered to programs for the early detection of cervical and breast cancer. The significant adherence to guidelines may be due to the schedule adopted by the local health public service, which regularly invites eligible subjects by mail to undergo cancer screening at no charge.

Abstract
INTRODUCTION Systemic sclerosis (SSc) and primary biliary cirrhosis (PBC) are rare polygenic autoimmune diseases (AIDs) characterized by fibroblast dysfunction. Furthermore, both diseases share some genetic bases with other AIDs, as evidenced by autoimmune gene pleiotropism. The present study was undertaken to investigate whether single-nucleotide polymorphisms (SNPs) identified by a large genome-wide association study (GWAS) in PBC might contribute to SSc susceptibility. METHODS Sixteen PBC susceptibility SNPs were genotyped in a total of 1,616 patients with SSc and 3,621 healthy controls from two European populations (France and Italy). RESULTS We observed an association between PLCL2 rs1372072 (odds ratio (OR) = 1.22, 95% confidence interval (CI) 1.12 to 1.33, P adj = 7.22 × 10(-5)), nuclear factor-kappa-B (NF-κB) rs7665090 (OR = 1.15, 95% CI 1.06 to 1.25, P adj = 0.01), and IRF8 rs11117432 (OR = 0.75, 95% CI 0.67 to 0.86, P adj = 2.49 × 10(-4)) with SSc susceptibility. Furthermore, phenotype stratification showed an association between rs1372072 and rs11117432 with the limited cutaneous subgroup (lcSSc) (P adj = 4.45 × 10(-4) and P adj = 0.001), whereas rs7665090 was associated with the diffuse cutaneous subtype (dcSSc) (P adj = 0.003). Genotype-mRNA expression correlation analysis revealed that the IRF8 protective allele was associated with increased interferon-gamma (IFN-γ) expression (P = 0.03) in patients with SSc but decreased type I IFN (IFIT1) expression in patients and controls (P = 0.02). In addition, we found an epistatic interaction between NF-κB and IRF8 (OR = 0.56, 95% CI 0.00 to 0.74, P = 4 × 10(-4)) which in turn revealed that the IRF8 protective effect is dependent on the presence of the NF-κB susceptibility allele. CONCLUSIONS An analysis of pleiotropic genes identified two new susceptibility genes for SSc (NF-κB and PLCL2) and confirmed the IRF8 locus. Furthermore, the IRF8 variant influenced the IFN signature, and we found an interaction between IRF8 and NF-κB gene variants that might play a role in SSc susceptibility.

Abstract
Objective The role of complement system in the pathogenesis of systemic sclerosis (SSc) has been debated during the last decade but an evident implication in this disease has never been found. We carried out an explorative study on SSc patients to evaluate the expression of soluble and local C5b-9 complement complex and its relation with a complement regulator, the Membrane Cofactor Protein (MCP, CD46) on skin vascular bed as target distinctive of SSc disease. We also analyzed two polymorphic variants in the complement activation gene cluster involving the MCP region. Methods C5b-9 plasma levels of SSc patients and healthy subjects were analyzed by ELISA assay. Archival skin biopsies of SSc patients and controls were subjected to immunofluorescence analysis to detect C5b-9 and MCP on vascular endothelial cells. The expression of MCP was validated by immunoblot analysis with specific antibody. Polymorphic variants in the MCP gene promoter were tested by a quantitative PCR technique-based allelic discrimination method. Results Even though circulating levels of C5b-9 did not differ between SSc and controls, C5b-9 deposition was detected in skin biopsies of SSc patients but not in healthy subjects. MCP was significantly lower in skin vessels of SSc patients than in healthy controls and was associated with the over-expression of two polymorphic variants in the MCP gene promoter, which has been related to more aggressive phenotypes in other immune-mediated diseases. Conclusions Our results firsty document the local complement activation with an abnormal expression of MCP in skin vessels of SSc patients, suggesting that a subset of SSc patients might be exposed to more severe organ complications and clinical evolution due to abnormal local complement activation.

Abstract
Objective. The aim of this study was to assess the prognostic value of systolic pulmonary artery pressure (sPAP) estimated by echocardiography in the multinational European League Against Rheumatism Scleroderma Trial and Research (EUSTAR) cohort. Methods. Data for patients with echocardiography documented between 1 January 2005 and 31 December 2011 were extracted from the EUSTAR database. Stepwise forward multivariable statistical Cox pulmonary hypertension analysis was used to examine the independent effect on survival of selected variables. Results. Based on our selection criteria, 1476 patients were included in the analysis; 87% of patients were female, with a mean age of 56.3 years (s.d. 13.5) and 31% had diffuse SSc. The mean duration of follow-up was 2.0 years (s.d. 1.2, median 1.9). Taking index sPAP of <30 mmHg as reference, the hazard ratio (HR) for death was 1.67 (95% CI 0.92, 2.96) if the index sPAP was between 30 and 36 mmHg, 2.37 (95% CI 1.14, 4.93) for sPAP between 36 and 40 mmHg, 3.72 (95% CI 1.61, 8.60) for sPAP between 40 and 50 mmHg and 9.75 (95% CI 4.98, 19.09) if sPAP was >50 mmHg. In a multivariable Cox model, sPAP and the diffusing capacity for carbon monoxide (DLCO) were independently associated with the risk of death [HR 1.833 (95% CI 1.035, 3.247) and HR 0.973 (95% CI 0.955, 0.991), respectively]. sPAP was an independent risk factor for death with a HR of 3.02 (95% CI 1.91, 4.78) for sPAP ≥36 mmHg. Conclusion. An estimated sPAP >36 mmHg at baseline echocardiography was significantly and independently associated with reduced survival, regardless of the presence of pulmonary hypertension based on right heart catheterization.

Abstract
Previous thrombosis, diagnosis of systemic lupus erythematosus (SLE) and triple antiphospholipid (aPL) antibody positivity have recently been found to be independent factors associated to pregnancy failure during conventional therapy in women with antiphospholipid syndrome (APS). This study aimed to assess the effect of various treatment strategies on pregnancy outcomes in women with APS and the risk factors for pregnancy failure. One hundred ninety-six pregnancies of 156 patients diagnosed with APS were analysed: 118 (60.2%) of these had previous thrombosis, 81 (41.3%) were diagnosed with SLE, and 107 (54.6%) had triple aPL positivity. One hundred seventy-five (89.3%) were treated with conventional therapies (low-dose aspirin [LDA] or prophylactic doses of heparin + LDA or therapeutic doses of heparin + LDA), while 21 (10.7%) were prescribed other treatments in addition to conventional therapy. The pregnancies were classified into seven risk profiles depending on the patients' risk factors - thrombosis, SLE, and triple aPL positivity - and their single, double or triple combinations. It was possible to find significant difference in outcomes correlated to treatments only in the thrombosis plus triple aPL positivity subset, and logistic regression analysis showed that additional treatments were the only independent factor associated to a favourable pregnancy outcome (odds ratio=9.7, 95% confidence interval=1.1-88.9, p-value<0.05). On the basis of this retrospective study, we found that APS pregnant patients with thrombosis and triple aPL positivity treated with additional therapy had a significant higher live-birth rate with respect to those receiving conventional therapy alone.

Abstract
OBJECTIVE Recognition of the well-known pleiotropism of autoimmune genes supports the concept of a shared pathogenesis across autoimmune diseases such as rheumatoid arthritis (RA) and systemic sclerosis (SSc). Studies have reproducibly demonstrated an association between susceptibility to RA and polymorphisms of the CCR6 gene, a surface marker for Th17 cells, and the causal variant was recently identified. The present study was thus undertaken to investigate whether CCR6 polymorphisms could also be associated with susceptibility to SSc. METHODS Twelve tag single-nucleotide polymorphisms (SNPs) of CCR6, including the known RA-associated SNP rs3093023, were genotyped in a total of 2,411 SSc patients and 7,084 healthy individuals from 3 European populations (France, Italy, and Germany). Meta-analyses of the data were performed to assess whether an association exists between CCR6 polymorphisms and susceptibility to SSc or its main subtypes. Direct sequencing of DNA was performed to ascertain whether the functional dinucleotide polymorphism of CCR6 previously identified in RA (CCR6DNP) was also present in SSc. RESULTS Combined analyses revealed an association between the rs10946216 SNP and SSc susceptibility (odds ratio [OR] 1.13, 95% confidence interval [95% CI] 1.05-1.21, adjusted P [P(adj)] = 0.026). The rs3093023 A allele and rs10946216 T allele were in high linkage disequilibrium, and both were found to confer disease susceptibility in the antitopoisomerase-positive subset of SSc patients (OR 1.27, 95% CI 1.13-1.42, P(adj) = 1.5 × 10(-3) and OR 1.32, 95% CI 1.17-1.48, P(adj) = 9.0 × 10(-5), respectively, relative to healthy controls). Direct sequencing of the DNA of 78 individuals supported the hypothesis that the regulatory dinucleotide CCR6DNP could be the causal variant in SSc. CONCLUSION The results of this study establish CCR6 as a new susceptibility factor for antitopoisomerase-positive SSc, as demonstrated in 3 European Caucasian populations, confirming the notion that SSc and RA could conceivably share autoimmune risk alleles. The results also suggest a potential role of the interleukin-17 pathway in SSc.

Abstract
OBJECTIVE To estimate the prevalence, determine the subgroups at risk, and the outcomes of patients with systemic sclerosis (SSc) and gastric antral vascular ectasia (GAVE). METHODS We queried the European League Against Rheumatism Scleroderma Trials and Research (EUSTAR) network for the recruitment of patients with SSc-GAVE. Each case was matched for cutaneous subset and disease duration with 2 controls with SSc recruited from the same center, evaluated at the time the index case made the diagnosis of GAVE. SSc characteristics were recorded at the time GAVE occurred and the last observation was collected to define the outcomes. RESULTS Forty-nine patients with SSc and GAVE were included (24 with diffuse cutaneous SSc) and compared to 93 controls with SSc. The prevalence of GAVE was estimated at about 1% of patients with SSc. By multivariate analysis, patients with SSc-GAVE more frequently exhibited a diminished (< 75%) DLCO value (OR 12.8; 95% CI 1.9-82.8) despite less frequent pulmonary fibrosis (OR 0.2; 95% CI 0.1-0.6). GAVE was also associated with the presence of anti-RNA-polymerase III antibodies (OR 4.6; 95% CI 1.2-21.1). SSc-GAVE was associated with anemia (82%) requiring blood transfusion (45%). Therapeutic endoscopic procedures were performed in 45% of patients with GAVE. After a median followup of 30 months (range 1-113 months), survival was similar in patients with SSc-GAVE compared to controls, but a higher number of scleroderma renal crisis cases occurred (12% vs 2%; p = 0.01). CONCLUSION GAVE is rare and associated with a vascular phenotype, including anti-RNA-polymerase III antibodies, and a high risk of renal crisis. Anemia, usually requiring blood transfusions, is a common complication.

Abstract
OBJECTIVE Whipple disease is a rare infection caused by Tropheryma whipplei. Although patients commonly complain of osteoarticular involvement, musculoskeletal manifestations have been poorly described. We report cases of Whipple disease with rheumatic symptoms and describe their clinical presentation, modes of diagnosis, and outcomes. METHODS This retrospective multicenter study included patients with Whipple disease diagnosed and referenced between 1977 and 2011 in 10 rheumatology centers in France and Italy. RESULTS Twenty-nine patients were included. The median age was 55 years. The median time to diagnosis from first symptoms was 5 years. Polyarthritis was the most frequent presentation (20/29), and was most often chronic, intermittent (19/29), seronegative (22/23), and nonerosive (22/29). In all cases, the symptoms had led to incorrect diagnosis of inflammatory rheumatic disease and immunosuppressants, including biotherapy, were prescribed in most cases (24/29) without success. The diagnosis of Whipple disease was made by histological analysis, molecular biology tests, or both in 21%, 36%, and 43% of the cases, respectively. Duodenal biopsies were performed in most cases (86%). Synovial biopsies were performed in 18% of cases, but all contributed to diagnosis. The clinical outcomes after antibiotic therapy were good for all patients. CONCLUSION Polyarthritis is the main feature observed in cases of Whipple disease; it is seronegative and associated with general and gastrointestinal symptoms. The molecular analysis of duodenal tissue and/or other tissues remains the method of choice to confirm the diagnosis. Reducing the time to diagnosis is important because severe late systemic and fatal forms of the disease may occur.

Abstract
The aims of this study were to evaluate body composition in systemic sclerosis (SSc) and to assess its association with the traditional risk factors for atherosclerosis and parameters of lung function. Eighty-six patients affected by SSc (13 men and 73 women, mean age 58.5 years, mean disease duration 10.7 years, 31 with diffuse form and 55 with limited pattern) underwent evaluation of body composition using a dual-energy X-ray (DXA) fan beam densitometer (GE Lunar iDXA) in order to assess total and regional body fat mass and fat-free mass. Clinical features, pulmonary function parameters, and the concomitant presence of the traditional cardiovascular risk factors were recorded. Android fat resulted to be higher in SSc patients with coexistence of hypercholesterolemia (P = 0.021), hypertension (P = 0.028), and overweight/obesity (P < 0.001) and positively correlated with body mass index (P < 0.001). Forced vital capacity (FVC) was inversely correlated with android fat (P = 0.034) and with the android fat/gynoid fat ratio (P = 0.013) and positively correlated with android lean (P = 0.041); the correlations were improved when FVC data were adjusted for sex, age, disease duration, and smoking habits (P = 0.010 for android fat, P = 0.010 for android fat/gynoid fat ratio, P = 0.011 for android lean). In this study, we showed that visceral abdominal fat, measured by DXA, is correlated with the main cardiovascular risk factors and lung volumes in SSc patients. Longitudinal studies are needed to evaluate if decrease of abdominal fat would improve lung function.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) share some pathophysiologic bases as evidenced by individual and familial polyautoimmunity and common susceptibility genetic factors. With regard to the latter, there has been a recent shift from the "common variant" to the "rare variant" paradigm, since rare variants of TNFAIP3 and TREX1 with large effect sizes have recently been discovered in SLE. The present study was undertaken to investigate whether rare variants of TNFAIP3 and TREX1 are also associated with SSc. METHODS TREX1 single-nucleotide polymorphisms (SNPs) rs3135946, rs7626978, rs3135943, and rs11797 and TNFAIP3 SNPs rs9494883, rs72063345, rs5029939, rs2230926, rs117480515, and rs7749323 were genotyped in a discovery set (985 SSc patients and 1,011 controls), and replication analysis of the most relevant results was performed in a second set (622 SSc patients and 493 controls). RESULTS No association between TREX1 variants and SSc was observed. For TNFAIP3, we first demonstrated that a low-frequency variant, rs117480515, tagged the recently identified TT>A SLE dinucleotide. In the discovery sample, we observed that all tested TNFAIP3 variants were in linkage disequilibrium and were associated with SSc and various SSc subsets, including the polyautoimmune phenotype. We subsequently genotyped rs117480515 in the replication sample and found it to be associated solely with the SSc polyautoimmune subset (odds ratio 3.51 [95% confidence interval 2.28-5.41], P = 8.58 × 10(-9) ) in the combined populations. Genotype-messenger RNA (mRNA) expression correlation analysis revealed that the TNFAIP3 rs117480515 risk allele was associated with decreased mRNA expression. CONCLUSION The present findings establish the TNFAIP3 locus as a susceptibility factor for the subset of SSc with a polyautoimmune phenotype. Our results support the implication of rare/low-frequency functional variants and the critical role of A20 in autoimmunity.

Abstract
IntroductionSystemic sclerosis (SSc)-related pulmonary arterial hypertension (PAH) has emerged as a major mortality prognostic factor. Mutations of transforming growth factor beta (TGFβ) receptor genes strongly contribute to idiopathic and
familial PAH.ObjectiveTo explore the genetic bases of SSc–PAH, we combined direct sequencing and genotyping of candidate genes encoding TGFβ receptor family members.Materials and methodsTGFβ receptor genes, BMPR2, ALK1, TGFR2 and ENG, were sequenced in 10 SSc–PAH patients, nine SSc and seven controls. In addition, 22 single-nucleotide polymorphisms (SNP) of these four candidate genes were tested for association in a first set of 824 French Caucasian SSc patients (including 54 SSc–PAH) and 939 controls. The replication set consisted of 1516 European SSc (including 219 SSc–PAH) and 3129 controls from the European League Against Rheumatism Scleroderma Trials and Research group network.ResultsNo mutation was identified by direct sequencing. However, two repertoried SNP, ENG rs35400405 and ALK1 rs2277382, were found in SSc–PAH patients only. The genotyping of 22 SNP including the latter showed that only rs2277382 was associated with SSc–PAH (p=0.0066, OR 2.13, 95% CI 1.24 to 3.65). Nevertheless, this was not replicated with the following result in combined analysis: p=0.123, OR 0.79, 95% CI 0.59 to 1.07.ConclusionsThis study demonstrates the lack of association between these TGFβ receptor gene polymorphisms and SSc–PAH using both sequencing and genotyping methods.

Abstract
OBJECTIVE To evaluate the prevalence of digital necrosis requiring surgical amputation in a single-center group of patients with systemic sclerosis (SSc) and to compare the characteristics of patients with and those without this severe complication. METHODS We reviewed the medical records of 188 patients with SSc [162 women, 26 men, mean age 59.2 yrs, mean disease duration 8.0 yrs, mean time from onset of Raynaud's phenomenon (RP) 11.7 yrs, median followup duration 92 mo] enrolled in the Rheumatology Unit since 2004. Demographic and clinical features were collected, as well as the presence of the typical risk factors for atherosclerosis. RESULTS Nine patients (4.8%) underwent partial or total surgical digital amputation because of necrotic process; all these patients except 1 had a long history of multiple and persisting digital ulcers. All 9 patients had concomitant large-vessel involvement. Comparison of cases with and without digital amputation showed that this complication was associated with older age, long history of RP, long disease duration, presence of anticentromere antibody, and coexistence of peripheral artery disease and hypercholesterolemia. Discussion. We noted that 4.8% of patients with SSc underwent digital amputation. Our retrospective analysis suggests that peripheral artery disease is strongly associated with digital amputation. The preventive strategy for digital ulcers and amputation associated with SSc should include an extensive diagnostic and preventive investigation for peripheral atherosclerosis.
