Int J Mol Sci 2024; 25:7227.

Abstract
Systemic sclerosis (SSc) is characterized by dermal fibrosis with a female predominance, suggesting a hormonal influence. Patients with SSc have elevated interleukin (IL)-6 levels, and post-menopausal women and older men also have high estradiol (E2) levels. In the skin, IL-6 increases the enzymatic activity of aromatase, thereby amplifying the conversion of testosterone to E2. Therefore, we hypothesized that an interplay between E2 and IL-6 contributes to dermal fibrosis. We used primary dermal fibroblasts from healthy donors and patients with diffuse cutaneous (dc)SSc, and healthy donor skin tissues stimulated with recombinant IL-6 and its soluble receptor (sIL-6R) or E2. Primary human dermal fibroblasts and tissues from healthy donors stimulated with IL-6+sIL-6R produced E2, while E2-stimulated dermal tissues and fibroblasts produced IL-6. Primary dermal fibroblasts from healthy donors treated with IL-6+sIL-6R and the aromatase inhibitor anastrozole (ANA) and dcSSc fibroblasts treated with ANA produced less fibronectin (FN), type III collagen A1 (Col IIIA1), and type V collagen A1 (Col VA1). Finally, dcSSc dermal fibroblasts treated with the estrogen receptor inhibitor fulvestrant also generated less FN, Col IIIA1, and Col VA1. Our data show that IL-6 exerts its pro-fibrotic influence in human skin in part through E2 and establish a positive feedback loop between E2 and IL-6.

Abstract
Background/Objectives: Calcinosis cutis is the deposition of insoluble calcium salts, which may cause inflammation, ulceration, pain, and restricted joint mobility. It rarely develops in damaged tissues (dystrophic subtype), most frequently in autoimmune connective tissue diseases (CTDs), but there is very limited data on the prevalence. Also, therapy remains an unsolved issue. In this study, we aimed to collect data on the prevalence of calcinosis in CTD patients to highlight that it is a considerable problem. Methods: A retrospective study was conducted in our department to assess the epidemiology of dystrophic calcinosis in CTDs between January 2003 and January 2024. Results: A total of 839 CTD patients were identified, of whom 56 had calcinosis (6.67%). The mean age of the calcinosis patients at diagnosis of underlying CTD was 41.16 ± 19.47 years. The mean time interval from the onset of calcinosis was 5.96 ± 8.62 years. Systemic sclerosis was the most common CTD complicated by calcinosis (n = 22). Conclusions: Our results are comparable to those reported previously in the literature. Although calcinosis is rare in the overall population, it is a present and unsolved problem in CTD patients. Therefore, further studies are needed on the factors involved in the development and progression of calcinosis as well as its treatment.

Distinct genome-wide DNA methylation and gene expression signatures in classical monocytes from African American patients with systemic sclerosis. Clin Epigenetics 2023; 15:25. [PMID: 36803404 PMCID: PMC9938585 DOI: 10.1186/s13148-023-01445-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 02/08/2023] [Indexed: 02/19/2023] Open
Abstract
BACKGROUND Systemic sclerosis (SSc) is a multisystem autoimmune disorder that has an unclear etiology and disproportionately affects women and African Americans. Despite this, African Americans are dramatically underrepresented in SSc research. Additionally, monocytes show heightened activation in SSc and in African Americans relative to European Americans. In this study, we sought to investigate DNA methylation and gene expression patterns in classical monocytes in a health disparity population. METHODS Classical monocytes (CD14+ + CD16-) were FACS-isolated from 34 self-reported African American women. Samples from 12 SSc patients and 12 healthy controls were hybridized on MethylationEPIC BeadChip array, while RNA-seq was performed on 16 SSc patients and 18 healthy controls. Analyses were computed to identify differentially methylated CpGs (DMCs), differentially expressed genes (DEGs), and CpGs associated with changes in gene expression (eQTM analysis). RESULTS We observed modest DNA methylation and gene expression differences between cases and controls. The genes harboring the top DMCs, the top DEGs, as well as the top eQTM loci were enriched for metabolic processes. Genes involved in immune processes and pathways showed a weak upregulation in the transcriptomic analysis. While many genes were newly identified, several other have been previously reported as differentially methylated or expressed in different blood cells from patients with SSc, supporting for their potential dysregulation in SSc. CONCLUSIONS While contrasting with results found in other blood cell types in largely European-descent groups, the results of this study support that variation in DNA methylation and gene expression exists among different cell types and individuals of different genetic, clinical, social, and environmental backgrounds. This finding supports the importance of including diverse, well-characterized patients to understand the different roles of DNA methylation and gene expression variability in the dysregulation of classical monocytes in diverse populations, which might help explaining the health disparities.

Fingerprint comparison between before disease onset and after systemic sclerosis diagnosis: a monocentric cross-sectional study. Clin Rheumatol 2023; 42:117-124. [PMID: 36042067 DOI: 10.1007/s10067-022-06353-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 08/14/2022] [Accepted: 08/20/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND Skin tightness is a hallmark of systemic sclerosis (SSc), and the fingers are an affected body part, so much so that fingerprints can be significantly affected among those with extensive skin tightness of the finger. OBJECTIVE We aimed to compare the difference between the current and past (pre-disease onset) fingerprints of SSc patients. METHODS We conducted a cross-sectional study among adult SSc patients who attended the Scleroderma Clinic, Khon Kaen University, between October 2019, and September 2020. All eligible patients consented to obtaining their current and previous prints from the Central Registration Bureau, Department of Provincial Administration, Ministry of the Interior. The current prints were obtained using the Crossmatch (Lite UE) live scan from the Central Institute of Forensic Science of Thailand. We investigated the concordance between the prints before disease onset and the current (enroll date) via the Printquest AFIS system with officers from the Central Institute of Forensic Science, Thailand. RESULTS One hundred SSc patients, according to the sample size calculation, were enrolled (mean age 59.4 ± 9.6 years; 66% female). Most (70%) had the diffuse cutaneous SSc subset. A respective 59%, 55%, and 6% presented acro-osteolysis, hand deformities, and digital ulcers. Some challenges were experienced in obtaining prints from patients with loss of the fingertip fat pad, finger joint contracture, and/or acro-osteolysis; notwithstanding, all fingerprints were usable and without individualized changes. CONCLUSION Fingerprints were affected by fingertip lesions and finger joint contractures; notwithstanding, the prints remained usable for personal identification. Key Points • Skin involvement in systemic sclerosis (SSc) affects the prints, particularly at the fingertip. • Despite disease onset, the fingerprints of SSc patients do not change significantly. • Fingerprints are inadequate for personal identification among SSc patients with hand deformities due to poor quality or difficulty acquiring them.

Abstract
Fibrosis has been shown to develop in individuals with underlying health conditions, especially chronic inflammatory diseases. Fibrosis is often diagnosed in various organs, including the liver, lungs, kidneys, heart, and skin, and has been described as excessive accumulation of extracellular matrix that can affect specific organs in the body or systemically throughout the body. Fibrosis as a chronic condition can result in organ failure and result in death of the individual. Understanding and identification of specific biomarkers associated with fibrosis has emerging potential in the development of diagnosis and targeting treatment modalities. Therefore, in this review, we will discuss multiple signaling pathways such as TGF-β, collagen, angiotensin, and cadherin and outline the chemical nature of the different signaling pathways involved in fibrogenesis as well as the mechanisms. Although it has been well established that TGF-β is the main catalyst initiating and driving multiple pathways for fibrosis, targeting TGF-β can be challenging as this molecule regulates essential functions throughout the body that help to keep the body in homeostasis. We also discuss collagen, angiotensin, and cadherins and their role in fibrosis. We comprehensively discuss the various delivery systems used to target collagen, angiotensin, and cadherins to manage fibrosis. Nevertheless, understanding the steps by which this molecule drives fibrosis development can aid in the development of specific targets of its cascading mechanism. Throughout the review, we will demonstrate the mechanism of fibrosis targeting to improve targeting delivery and therapy.

Development and validation of machine learning for early mortality in systemic sclerosis. Sci Rep 2022; 12:17178.

Abstract
Clinical predictors of mortality in systemic sclerosis (SSc) are diversely reported due to different healthcare conditions and populations. A simple predictive model for early mortality among patients with SSc is needed as a precise referral tool for general practitioners. We aimed to develop and validate a simple predictive model for predicting mortality among patients with SSc. Prognostic research with a historical cohort study design was conducted between January 1, 2013, and December 31, 2020, in adult SSc patients attending the Scleroderma Clinic at a university hospital in Thailand. The data were extracted from the Scleroderma Registry Database. Early mortality was defined as dying within 5 years after the onset of SSc. Deep learning algorithms with Adam optimizer and different machine learning algorithms (including Logistic Regression, Decision tree, AdaBoost, Random Forest, Gradient Boosting, XGBoost, and Autoencoder neural network) were used to classify SSc mortality. In addition, the model's performance was evaluated using the area under the receiver operating characteristic curve (auROC) and its 95% confidence interval (CI) and values in the confusion matrix. The predictive model development included 528 SSc patients, 343 (65.0%) were females and 374 (70.8%) had dcSSc. Ninety-five died within 5 years after disease onset. The final 2 models with the highest predictive performance comprise the modified Rodnan skin score (mRSS) and the WHO-FC ≥ II for Model 1 and mRSS and WHO-FC ≥ III for Model 2. Model 1 provided the highest predictive performance, followed by Model 2. After internal validation, the accuracy and auROC were good. The specificity was high in Models 1 and 2 (84.8%, 89.8%, and 98.8% in model 1 vs. 84.8%, 85.6%, and 98.8% in model 2). This simplified machine learning model for predicting early mortality among patients with SSc could guide early referrals to specialists and help rheumatologists with close monitoring and management planning. External validation across multi-SSc clinics should be considered for further study.

Abstract
Background Skin thickness is a prominent clinical feature of systemic sclerosis (SSc), but there is no consensus on the cut-off for a positive tuberculin skin test (TST) size and the limitation of the TST for a diagnosis of tuberculosis in SSc. We aimed to identify the cut-off size of an indurated TST and the sensitivity and specificity of the test for the diagnosis of tuberculosis in SSc patients. Methods A cross-sectional study of 168 adult Thai SSc patients was conducted. The TST was done using 0.1 ml of purified protein derivatives via intradermal injection. The test was interpreted 72 h after testing. Results The median age was 57.2 years. The majority (71.8%) had the diffuse cutaneous SSc subset. All the patients had a BCG vaccination at birth, and 17 (10.1%) had a tuberculosis infection. An indurated skin reaction size of 20 mm had the highest specificity for tuberculosis (99.3%: 95%CI 96.4–100) (ROC 0.53). The skin thickness—assessed using the modified Rodnan skin score (mRSS)—had a significant negative correlation with the reaction size (Rho -0.23; p = 0.003). Conclusion The TST is not sufficiently sensitive for detecting TB infection in SSc patients, albeit a skin induration of ≥ 15 mm indicates a high specificity for tuberculosis infection. A high mRSS resulted in a smaller skin reaction size when using the TST, which has limited utility as a diagnostic for tuberculosis among SSc patients with severe skin thickness.

Abstract
Connective tissue diseases (CTDs) include a spectrum of disorders that affect the connective tissue of the human body; they include autoimmune disorders characterized by immune-mediated chronic inflammation and the development of fibrosis. Lung involvement can be misdiagnosed, since pulmonary alterations preceded osteo-articular manifestations only in 20% of cases and they have no clear clinical findings in the early phases. All pulmonary structures may be interested: pulmonary interstitium, airways, pleura and respiratory muscles. Among these autoimmune disorders, rheumatoid arthritis (RA) is characterized by usual interstitial pneumonia (UIP), pulmonary nodules and airway disease with air-trapping, whereas non-specific interstitial pneumonia (NSIP), pulmonary hypertension and esophageal dilatation are frequently revealed in systemic sclerosis (SSc). NSIP and organizing pneumonia (OP) may be found in patients having polymyositis (PM) and dermatomyositis (DM); in some cases, perilobular consolidations and reverse halo-sign areas may be observed. Systemic lupus erythematosus (SLE) is characterized by serositis, acute lupus pneumonitis and alveolar hemorrhage. In the Sjögren syndrome (SS), the most frequent pattern encountered on HRCT images is represented by NSIP; UIP and lymphocytic interstitial pneumonia (LIP) are reported with a lower frequency. Finally, fibrotic NSIP may be the interstitial disease observed in patients having mixed connective tissue diseases (MCTD). This pictorial review therefore aims to provide clinical features and imaging findings associated with autoimmune CTDs, in order to help radiologists, pneumologists and rheumatologists in their diagnoses and management.

Abstract
Background Immunosuppression remains the main treatment for progressing skin involvement, interstitial lung disease and inflammatory joint or muscle disease in systemic sclerosis. This study investigated the pattern and trends in immunosuppressive agents used in early systemic sclerosis (diagnosed before and after 2007) to determine whether the changes in the preferred type, timing and combination of immunosuppression took place over the past decade. Methods In total, 397 Canadian Scleroderma Research Group database patients (183 diffuse cutaneous systemic sclerosis and 214 limited cutaneous systemic sclerosis) who had baseline and follow-up visits within 3 years (mean: 1.8 ± 0.8) after disease onset were included: 82% females, age at diagnosis 53 ± 13 years. Bivariate, chi-square, analysis of variance and adjusted regression analyses were used. Results In total, 115 diffuse cutaneous systemic sclerosis patients (63%) and 62 limited cutaneous systemic sclerosis (29%) received immunosuppressive drugs, most commonly methotrexate, followed by mycophenolate mofetil and cyclophosphamide. In diffuse cutaneous systemic sclerosis, immunosuppressants were prescribed after 2007 more often (74% vs 50%, p = 0.001), especially methotrexate (p = 0.02) and mycophenolate mofetil (p = 0.04), and earlier (peak at 2 years after onset). Immunosuppressive therapy was associated with male gender, interstitial lung disease, anti-Scl70 positivity, ACA negativity and inflammatory joint disease in limited cutaneous systemic sclerosis and with ACA negativity and a higher modified Rodnan skin score in diffuse cutaneous systemic sclerosis. Multivariate regression analysis showed that the use of immunosuppressants after 2007 was predicted only by ACA negativity in limited cutaneous systemic sclerosis and by younger age in diffuse cutaneous systemic sclerosis. Conclusion Over the past decade, there has been a trend to prescribe immunosuppressants more often and earlier in diffuse cutaneous systemic sclerosis patients, regardless of modified Rodnan skin score. Methotrexate is being more frequently used, and mycophenolate mofetil has gained favour over cyclophosphamide. Autoantibody status was the most consistent predictor of immunosuppressive therapy.

Abstract
RATIONALE Pruritus is a common symptom in patients with systemic sclerosis and has a tremendous effect on the quality of life. Nevertheless, current therapeutic options are limited. The pathogenesis of pruritus in systemic sclerosis is not completely understood; however, opiate-mediated neurotransmission has been postulated to be involved. PATIENT CONCERNS AND DIAGNOSIS We describe 4 female patients with systemic sclerosis suffering from severe pruritus, with an average 5D-itch score of 22.75. INTERVENTION AND OUTCOMES Low-dose oral naloxone was initiated, followed by a significant improvement in the level of pruritus, reaching an average 5D-itch score of 7.5, after 6 and 12 months of treatment. None of the patients experienced side effects. LESSONS Low-dose naloxone plays an important role in the management of pruritus in systemic sclerosis.

Aerosol components associated with hospital mortality in systemic sclerosis: an analysis from a nationwide Thailand healthcare database. Sci Rep 2021; 11:7983. [PMID: 33846466 PMCID: PMC8042026 DOI: 10.1038/s41598-021-87114-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 03/22/2021] [Indexed: 11/25/2022] Open
Abstract
Occupational and environmental associations with systemic sclerosis (SSc) have been confirmed; however, the association between aerosol components and mortality is uncertain. The study aimed to define the association between aerosol components and hospital mortality among Thai SSc patients. A study was conducted using a national database of patients covered by the National Health Security Office, hospitalised between 2014 and 2018. Data included all patients over 18 having a primary diagnosis of SSc (ICD-10: M34). Spatial resources used map information based on GPS coordinates of Thailand. Aerosol components—including organic carbon, black carbon, dust particulate matter diameter < 2.5 µm (PM2.5), and sulfate—were assessed using the NASA satellite MERRA-2 Model M2TMNXFLX v5.12.4. Spatial modelling with R Package Integrated Nested Laplace Approximation (R-INLA) was used to analyse the association between the incidence of mortality and the 5-year accumulation of each aerosol component adjusted by age, sex, and comorbid diseases. The study included 2,094 SSc patients with 3,684 admissions. Most (63.8%) were female. During admission, 1,276 cases died. R-INLA analysis indicated an increase of 1 µg/m3 of dust PM2.5 was associated with a respective increase in the risk of overall mortality and death due to pneumonia of 96% and 79%. An increase of 1 µg/m3 of dust PM2.5 resulted in 1.17, 1.18, 1.64, and 2.15 times greater risk of mortality due to pulmonary fibrosis, cardiac involvement, renal involvement, and cancer, respectively. Aerosol components—particularly dust PM2.5 exposures—increased the risk of overall, cardio-pulmonary-renal, and cancer mortality among SSc patients.

Differential DNA Methylation Landscape in Skin Fibroblasts from African Americans with Systemic Sclerosis. Genes (Basel) 2021; 12:129. [PMID: 33498390 PMCID: PMC7909410 DOI: 10.3390/genes12020129] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 01/15/2021] [Accepted: 01/18/2021] [Indexed: 01/20/2023] Open
Abstract
The etiology and reasons underlying the ethnic disparities in systemic sclerosis (SSc) remain unknown. African Americans are disproportionally affected by SSc and yet are underrepresented in research. The aim of this study was to comprehensively investigate the association of DNA methylation levels with SSc in dermal fibroblasts from patients of African ancestry. Reduced representation bisulfite sequencing (RRBS) was performed on primary dermal fibroblasts from 15 SSc patients and 15 controls of African ancestry, and over 3.8 million CpG sites were tested for differential methylation patterns between cases and controls. The dermal fibroblasts from African American patients exhibited widespread reduced DNA methylation. Differentially methylated CpG sites were most enriched in introns and intergenic regions while depleted in 5' UTR, promoters, and CpG islands. Seventeen genes and eleven promoters showed significant differential methylation, mostly in non-coding RNA genes and pseudogenes. Gene set enrichment analysis (GSEA) and gene ontology (GO) analyses revealed an enrichment of pathways related to interferon signaling and mesenchymal differentiation. The hypomethylation of DLX5 and TMEM140 was accompanied by these genes' overexpression in patients but underexpression for lncRNA MGC12916. These data show that differential methylation occurs in dermal fibroblasts from African American patients with SSc and identifies novel coding and non-coding genes.

Abstract
INTRODUCTION Anti-neutrophilic cytoplasmic antibody (ANCA) has been reported in systemic sclerosis (SSc). Some clinical features of SSc can also be presented with ANCA-associated vasculitis. Objectives were to determine the prevalence and clinical associations with ANCA among Thais with SSc. MATERIAL AND METHODS A cross-sectional study of Thai adult SSc patients was conducted. According to the sample size calculation, 185 patients were included. Clinical and laboratory tests for serology and others for evaluation of the clinical association with ANCA were done simultaneously on the study date. RESULTS The female to male ratio was 2 : 1. The majority had the diffuse SSc subset (71.2%). The respective prevalence of having a) at least 1 serological test for ANCA (viz., perinuclear ANCA, cytoplasmic ANCA, anti-myeloperoxidase, or anti-proteinase3), b) positive for either p-ANCA or c-ANCA, c) positive for either anti-MPO or anti-PR3, d) p-ANCA and anti-MPO and e) c-ANCA and anti-PR3 was 21.6% (95% CI: 15.9-28.3), 11.9% (95% CI: 7.6-17.4) and 13.0% (95% CI: 8.5-18.7) and 1% (95% CI: 0.1-3.9). By multivariate analysis, the erythrocyte sedimentation rate elevation was significantly associated with the presence of the antibody (OR = 11.36, 95% CI: 1.44-83.65), while elevation of high sensitivity cardiac troponin-T (hs-cTnT) was significantly associated with the presence of either p-ANCA or c-ANCA (OR = 4.25, 95% CI: 1.41-15.34). None of the patients had clinical features of systemic vasculitis. CONCLUSIONS Around one-fifth of SSc patients have detectible ANCA without any features of vasculitis. The presence of ANCA is associated with inflammation and myocardial injury. ANCA is not antibody specific for vasculitis in SSc.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disorder with a high mortality rate. There are still many unknowns concerning the pathophysiology of this disease, due to its clinical heterogeneity. Since there is still no curative treatment, researchers focus on finding novel methods to help the patients. One of the valid options is cellular therapy, and mesenchymal stem cells (MSCs)-based therapy yields great expectations. These cells possess especially valuable attributes regarding key points of SSc. Nevertheless, the effectiveness and safety of this therapy must undergo a rigorous process of verification. In preclinical trials, animal models proved to be a valuable source of scientific knowledge regarding SSc. Because of that, it has been possible to test autologous or allogeneic MSCs from various sources in many clinical trials. A lot of aspects still have to be determined to assess their potential in the management of SSc, probably in association with other therapies.

Abstract
BACKGROUND Most Thai patients with systemic sclerosis (SSc) have diffuse cutaneous SSc (dcSSc) unlike most Caucasians and some Asians. A longitudinal cohort study among Thai dcSSc is needed. OBJECTIVES We aimed to determine the overall clinical characteristics, define the clinical difference between limited cutaneous SSc (lcSSc) and dcSSc, and ascertain the mortality rate and the factors associated with mortality. METHOD We conducted a cohort study including 566 Thai adult SSc patients between January 2013 and June 2019. Clinical difference between lcSSc and dcSSc was investigated using generalized estimating equations (GEE). RESULTS Females presented more than males (356 vs 210 cases). The majority of cases were dcSSc (411; 72.6%). The median duration of disease at the time of pulmonary fibrosis (PF) detection was 2.5 years, pulmonary arterial hypertension 8.1 years, and renal crisis 4.1 years. By GEE analysis, dcSSc was significantly associated with salt-and-pepper skin, hand deformity, and every 1-point increase in modified Rodnan skin score (mRSS). A greater mortality risk was associated with age at onset >60 years (hazards ratio [HR] 5.5), a World Health Organization functional class (FC) III (HR 5.1), FC IV (HR 34.8), edematous skin (HR 11.4), early onset of PF (HR 1.7), each 5-point increase in the mRSS (HR 4.5), and ≥2 internal organ involvements (HR 10.1). CONCLUSION dcSSc is a common SSc subset among Thais. PF was an early complication in SSc and earlier PF detection was associated with a poorer prognosis. Elderly onset, high FC, severe skin tightness, and multiple organ involvements were associated with a greater mortality risk.

Abstract
Objectives: We aimed to determine rate of admission, mortality rate, and causes of death in systemic sclerosis (SSc) patients after stratifying by season.Method: A cross-sectional analysis was performed of patients over 15 in the national database with a primary diagnosis of SSc (ICD-10:M34) covered by the National Health Security Office hospitalized between 2014 and 2018. The seasons were stratified into hot, rainy, and Cool dry seasons.Results: Included were 2480 SSc patients with 3684 admissions: most (64.3%) were female. The respective mean age and median length of stay was 56.9 ± 12.3 years and 3 days (IQR 2-6). The admission rate was highest during the rainy season (1574 visits, 42.7%), followed by the cool dry season (1183 visits, 32.1%) then the hot season (927 visits, 25.2%). During the 13,180 person-days, 1660 SSc patients died resulting in a mortality rate of 12.1 per 100 person-days. The proportion of SSc patients who died in the Cool dry season was significantly higher than in the hot or rainy season (p = .04). Pulmonary involvement in SSc was the most common cause of death in the hot season, which is greater than in the other seasons (p = .004). By comparison, death due to cardiac involvement in SSc was common during the rainy season and cool dry seasons (p = .04).Conclusion: The admission rate among Thai SSc patients was greatest during the rainy season, while mortality was highest during the cool dry season. The most common causes of death were SSc-related irrespective of season, particularly cardiopulmonary involvement.

Abstract
BACKGROUND Autoimmune thyroid disease affects 1% of the general population, and autoimmune thyroid antibodies are noted in up to 15%. OBJECTIVE We hypothesized systemic sclerosis (SSc) is associated with higher prevalence of antithyroglobulin (anti-Tg) and anti-thyroid peroxidase (anti-TPO) antibodies) to justify monitoring of thyroid function for earlier detection and treatment. METHODS Waikato Hospital SSc clinic patients were prospectively tested for thyroid function tests and antithyroid antibodies (ATAs). RESULTS Of the 75 patients with SSc and 10 patients with SSc overlap syndrome (SOS) followed up in the SSc clinic, anti-Tg and anti-TPO were prospectively tested in 61 (70.6%) of the 85 patients. The cohort comprised 38 patients with limited cutaneous SSc (lcSSc), 15 with diffuse cutaneous SSc, and 8 with SOS.Anti-Tg and anti-TPO antibodies were found in 34.2% in lcSSc patients and 33.3% in diffuse cutaneous SSc patients, whereas in SOS they were found in 25% (Tg) and in 12.5% (TPO) of patients.At baseline, 10 patients (11.7%) had thyroid dysfunction: 8 (9.4%) with subclinical hypothyroidism and 1 each (1.2%) with subclinical hyperthyroidism and with clinical hyperthyroidism.After 18 months, 1 woman with lcSSc, positive for both ATAs, developed clinical hypothyroidism. CONCLUSIONS There is a higher prevalence of ATAs in SSc and SOS compared with the general population. Screening these patients for ATAs is a reasonable measure.

Abstract
INTRODUCTION Idiopathic scrotal calcinosis is a rare benign condition which presents with asymptomatic multiple nodules on the scrotal skin. PRESENTATION OF CASE Our patient, a 64-year-old Indian male with Fitzpatrick skin type 4, presented with multiple nodules, which were completely surgically excised with no complications. Histological examination reveals extensive intradermal deposition of calcium surrounded by histiocytes and without cystic structure. DISCUSSION Numerous theories about the pathogenesis have been proposed and the evidence presented suggests this is a continuum. CONCLUSION The nature of idiopathic scrotal calcinosis is still unknown and it is up to debate whether the term "idiopathic" is appropriate for the condition.

Abstract
Background Werner syndrome is a progeroid disorder characterized by premature age-related phenotypes. Although it is well established that autosomal recessive mutations in the WRN gene is responsible for Werner syndrome, the molecular alterations that lead to disease phenotype remain still unidentified. Results To address whether epigenetic changes can be associated with Werner syndrome phenotype, we analysed genome-wide DNA methylation profile using the Infinium MethylationEPIC BeadChip in the whole blood from three patients affected by Werner syndrome compared with three age- and sex-matched healthy controls. Hypermethylated probes were enriched in glycosphingolipid biosynthesis, FoxO signalling and insulin signalling pathways, while hypomethylated probes were enriched in PI3K-Akt signalling and focal adhesion pathways. Twenty-two out of 47 of the differentially methylated genes belonging to the enriched pathways resulted differentially expressed in a publicly available dataset on Werner syndrome fibroblasts. Interestingly, differentially methylated regions identified CERS1 and CERS3, two members of the ceramide synthase family. Moreover, we found differentially methylated probes within ITGA9 and ADAM12 genes, whose methylation is altered in systemic sclerosis, and within the PRDM8 gene, whose methylation is affected in dyskeratosis congenita and Down syndrome. Conclusions DNA methylation changes in the peripheral blood from Werner syndrome patients provide new insight in the pathogenesis of the disease, highlighting in some cases a functional correlation of gene expression and methylation status.

Abstract
OBJECTIVE Autoantibody profiles in systemic sclerosis (SSc) and their relative clinical association vary between studies. The rate for being anti-topoisomerase-I (ATA) positive and the association with diffuse cutaneous the SSc subset (dcSSc) is higher among Thais than among Caucasians. The objective was to evaluate the relevance of clinical presentation, namely being positive for one or more autoantibodies among Thai SSc patients. METHOD A retrospective, cohort study was performed among SSc patients over 18 years of age at Srinagarind Hospital, Khon Kaen University, Thailand, during January 2006 to December 2013. Autoantibodies comprising 13 SSc-specific antigens were evaluated using the EUROIMMUN AG (Lübeck, Germany) in order to define their clinical association(s). RESULTS Two hundred and eighty-five scleroderma patients (200 female; 85 male) were included. The majority (66.7%) were dcSSc subset. ATA was the most common antibody profile in our patients (231 cases; 81.1%), followed by anti-Ro 52 (87 cases; 30.5%). Eleven of our patients (3.9%) were negative for all antibody profiles and 44 cases (15.4%) were negative for ATA and anti-centromere antibody (anti-CENP). Almost 40% (112 cases) were positive for at least two autoantibodies. There was an association between the presence of ATA and hand deformity (odds ratio [OR] 3.94; 95% CI 1.12-13.84), anti-CENP and hand deformity (OR 0.20; 95% CI 0.02-0.90), anti-Ku and scleroderma-polymyositis overlap syndrome (OR 6.58; 95% CI 2.16-19.39) and the absence of both ATA and anti-CENP with female sex (OR 2.90; 95% CI 1.12-7.51), limited cutaneous SSc subset (OR 2.70; 95% CI 1.30-5.55) and scleroderma-polymyositis overlap syndrome (OR 2.53; 95% CI 1.04-6.16). Neither ATA nor anti-CENP were associated with the SSc subset. CONCLUSIONS ATA and anti-CENP were not helpful in differentiating the SSc subset in Thai SSc patients, albeit they were good for predicting hand function. Coexisting ATA and anti-CENP negativity were associated with less extensive skin tightness and SSc overlap syndrome.

Abstract
RISE-SSc is a randomized, double-blind, placebo-controlled phase 2 study investigating the efficacy and safety of riociguat in patients with diffuse cutaneous systemic sclerosis (dcSSc). Based on positive results from riociguat trials in patients with pulmonary hypertension and chronic thromboembolic pulmonary hypertension in combination with the known antiproliferative and antifibrotic effects seen in animal models, patients with SSc may benefit from treatment with riociguat. Patients with SSc meeting the ACR/EULAR systemic sclerosis classification criteria with diffuse cutaneous SSc (dcSSc) subset per LeRoy criteria, and a disease duration of less than or equal to 18 months will be randomized to placebo or riociguat 0.5 mg (up-titrated to a maximum dose of 2.5 mg TID over 10 weeks) and maintained on therapy for a total of 52 weeks. During the first 10 weeks of the long-term extension phase, placebo subjects will be up-titrated on riociguat, and all patients will be followed for up to 6 years. The primary endpoint of change in modified Rodnan skin score (mRSS) from baseline will be assessed at 52 weeks, as will be secondary endpoints such as mRSS progression and regression rates, patient quality of life, digital ulcer burden, and change in forced vital capacity and carbon monoxide diffusing capacity. This review will further define the clinical rationale for the use of riociguat in the treatment of SSc and provide details on study protocol, design, and outcome reporting. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT02283762.

Abstract
INTRODUCTION Spirometry is a screening tool for evaluating the degree of restrictive lung disease in systemic sclerosis (SSc). Observations indicated that some patients could not complete the test. The aim of the study was to identify the prevalence, causes and clinical predictors of an inadequate pulmonary function test (PFT) in SSc. MATERIAL AND METHODS A cross-sectional study was performed among SSc patients over 18 years old followed up at Srinagarind Hospital, Khon Kaen, Thailand, during January 2006-December 2012. The adequacy of the PFT was based on the acceptable blow criteria as set out by the American Thoracic Society and the European Respiratory Society 2005 Standardizations of Spirometry. RESULTS Two hundred and forty-nine patients were included (female to male ratio was 2 : 1). The mean age at performing PFT was 51.4 ±11.1 years (range: 19.6-79.5). Median duration of disease at performing PFT was 2 years (IQR: 0.6-4.4). Inadequate PFT occurred in 73 cases (prevalence 29.3%: 95% CI: 23.6-35.0); the majority (60 cases; 82.2%) had an expiration time < 6 s and the others were due to plateau < 1 s (11 cases; 15%), air leak around mouth piece (1 case; 1.4%) and hesitation (1 case; 1.4%). Thirteen of 73 (17.8%) had an unusable graph with the overall prevalence of 5.2% (95% CI: 2.4-8.0). The factor associated with inadequate PFT was docy mass index (BMI) < 18.5 kg/m(2) (OR = 2.17: 95% CI: 1.49-3.17); the same factor was associated with an unusable graph, which was confirmed by the multivariate analysis (OR = 5.21; 95% CI: 1.60-16.95). CONCLUSIONS One-third of Thai SSc patients had an inadequate pulmonary function test - the majority because of inadequate time for expiring. Low BMI influenced the effectiveness of the test, leading to an incomplete graph for evaluating lung disease in SSc.

Abstract
Systemic sclerosis is a multifactorial and heterogeneous disease. Genetic and environmental factors are known to interplay in the onset and progression of systemic sclerosis. Sex plays an important and determinant role in the development of such a disorder. Systemic sclerosis shows a significant female preponderance. However, the reason for this female preponderance is incompletely understood. Hormonal status, genetic and epigenetic differences, and lifestyle have been considered in order to explain female preponderance in systemic sclerosis. Sex chromosomes play a determinant role in contributing to systemic sclerosis onset and progression, as well as in its sex-biased prevalence. It is known, in fact, that X chromosome contains many sex- and immuno-related genes, thus contributing to immuno tolerance and sex hormone status. This review focuses mainly on the recent progress on epigenetic mechanisms--exclusively linked to the X chromosome--which would contribute to the development of systemic sclerosis. Furthermore, we report also some hypotheses (dealing with skewed X chromosome inactivation, X gene reactivation, acquired monosomy) that have been proposed in order to justify the female preponderance in autoimmune diseases. However, despite the intensive efforts in elucidating the mechanisms involved in the pathogenesis of systemic sclerosis, many questions remain still unanswered.

Abstract
BACKGROUND Anti-topoisomerase I antibody (ATA) carries an increased risk of systemic sclerosis (SSc) internal organ involvement. There have been no published comparisons of the clinical characteristics of patients positive and negative for ATA in Thailand, where the positive rate for ATA is higher than among Caucasians. OBJECTIVE To define the clinical differences between SSc, positive versus negative, for ATA. METHODS A retrospective cohort study was performed among SSc patients over 18 at Srinagarind Hospital, Khon Kaen University, Thailand, during January 2006-December 2013. SSc-overlap syndrome was excluded. RESULTS Two hundred and ninety-four SSc patients were included (female : male 2.5 : 1). The majority (68.6%) were the diffuse cutaneous SSc subset (dcSSc). ATA was positive in 252 patients (85.7%), among whom 71.7% had dcSSc and 28.2% limited cutaneous SSc (lcSSc). Using a multivariate analysis, hand deformity had a significantly positive association with ATA (odds ratio [OR] 7.01; 95% CI 1.02-48.69), whereas being anti-centromere (ACA) positive had a negative association (OR 0.17; 95% CI 0.03-0.92). After doing a subgroup analysis of the SSc subset, the median duration of disease at time of pulmonary fibrosis detection among ATA positive dcSSc was significantly shorter than the ATA negative group (1.05 vs. 6.77 years, P = 0.01). Raynaud's phenomenon (RP) at onset was significantly more frequent in lcSSc sufferers who were ATA negative than those who were ATA positive (90.5% vs. 56.9%, P = 0.005). CONCLUSIONS A high prevalence of ATA positivity was found among Thai SSc patients and this was associated with a high frequency of hand deformity, ACA negativity, a short duration of pulmonary fibrosis in dcSSc and a lower frequency of RP in lcSSc.

Abstract
The aim of this study was to evaluate efficacy of azathioprine (AZA) and cyclophosphamide (CYC) as a therapeutic regimen for interstitial lung disease associated with systemic sclerosis (SSc). Thirty-six selected patients included in this retrospective cohort and received one of the two drugs; the first group consists of 15 patients who were treated with AZA (1.5-2 mg/kg/day) and the second group with 21 patients received oral CYC (up to 2 mg/kg/day). Both groups received additional low dose of prednisolone (≤10 mg) for 6 months. Forced vital capacity (FVC), diffusion lung capacity for carbon monoxide (DLCO) and skin score were assessed as outcome measures. Modified Rodnan skin score (mRSS), pulmonary function test and DLCO were evaluated at entry and at the end of study after 12 months. The mean (SD) FVC percentages obtained at baseline and post-treatment in AZA-treated patients were 62.8 ± 9.8 and 71.1 ± 20.9 with mean difference of FVC% +7.6 ± 13.1, p = 0.05, and in CYC-treated patients 59.5 ± 10.7, 63.1 ± 16.2 and +2.9 ± 11.5, respectively, p = 0.19. Baseline and post-treatment DLCO% in AZA-treated patients were 61.4 ± 25.8 and 76.7 ± 24.0 with mean difference of +15.0 ± 14.5, respectively, p = 0.01. In CYC-treated patients, those measures were 67.7 ± 27.5 and 60.0 ± 22.9 with mean difference of -8.0 ± 23.7 (p = 0.12). Following 12 months of treatment in AZA-treated patients, mean difference of changes in mRSS was -2.9 ± 3.7 and -1.4 ± 4.5 in CYC-treated patients. Our results indicated that AZA can be effective in ameliorating or stabilizing lung function in selected SSc patient groups.

Abstract
Connective tissue disorders are systemic, autoimmune, multiorgan diseases in which the central and peripheral nervous systems are frequently involved. The objective of this chapter is to describe the neurological manifestations of three of the most common systemic autoimmune disorders: systemic lupus erythematosus (SLE), scleroderma, and Sjögren's syndrome (SS). In SLE the neuropsychiatric manifestations involve mainly the central nervous system (CNS), including cognitive dysfunction, headache, psychosis and mood changes, seizures, cerebrovascular disease, and myelopathy. Peripheral nervous system (PNS) manifestations are less common and include polyneuropathies as well as mononeuropathies and acute inflammatory demyelinating polyneuropathy. Antiphospholipid syndrome (APLS) is relatively common and should be searched for whenever focal neurological symptoms occur. In scleroderma the PNS is more commonly involved; symptoms include polyneuropathies, entrapment neuropathies, and mononeuropathies (mostly cranial neuropathies or mononeuritis multiplex). Additionally autonomic involvement occurs and myopathies are relatively common. In SS the PNS is similarly involved with several types of polyneuropathies, mononeuropathies, and autonomic dysfunction. Also common are myelopathies and aseptic meningitides. These and other, less common manifestations, as well as the diagnostic procedures and the therapeutic approaches, will be dealt with in this chapter.

Abstract
BACKGROUND To determine the usefulness of Ca 15.3 as a candidate biomarker in systemic sclerosis (SSc) patients with interstitial lung disease (ILD). METHODS Two-hundred-twenty-one SSc patients with Ca 15.3 determinations were considered; 168 had evidence of interstitial lung involvement on high-resolution computed tomography (HRCT); digitalized scans were available for scoring in 84 subjects. Discrimination between patients with or without ILD, was assessed by receiving operating characteristics (ROC) analysis; correlations between HRCT scores and Ca 15.3 were performed. Survival and serial pulmonary function tasting (PFT) data were used for prognostication. RESULTS Ca 15.3 serum levels strongly correlated with HRCT scores (r=0.734, p<0.0001) which were predictors of survival at the 20% threshold (p=3.1∗10(-4)). Ca 15.3 had an area under ROC to detect the meaningful 20% fibrosis extent equal to 0.927 and abnormal Ca 15.3 values were capable of differentiating between patients at hi- or low-risk for progression in the group with undetermined disease extent (HR=3.209, confidence interval [CI95]=1.56-6.602, p=0.002). Ca 15.3 outperformed other PFT measures in providing a separation of survival estimates where HRCT scans are unavailable. The combined use of HRCT scores and Ca 15.3 in SSc-ILD patients was more discriminatory (HR=4.824, CI95=2.612-8.912, p<0.0001) than the staging system based on HRCT scores plus FVC (HR=2.657, CI95=1.703-4.147, p<0.0001) and characterized by lower prediction errors (0.2134 vs 0.2234). CONCLUSION Ca 15.3 is a rapid and inexpensive candidate biomarker for SSc-ILD being proportional to the extent of lung injury and specific and sensitive in assessing meaningful extents of the disease with prognostic significance.

Abstract
Calcinosis cutis is a chronic condition involving insoluble calcified deposits of the skin and subcutaneous tissue. It is commonly associated with autoimmune connective tissue diseases and can be a source of pain and functional disability. The likelihood of developing calcinosis varies among the autoimmune connective tissue diseases, with systemic sclerosis and dermatomyositis being the most commonly associated. Identification of therapy for this challenging disorder has been hampered by a paucity of large controlled trials. Although there is no uniformly effective treatment for calcinosis cutis, several surgical and medical therapies have demonstrated varying degrees of benefit in the treatment of calcinosis, including surgical excision, laser therapy, extracorporeal shock wave lithotripsy, diltiazem, minocycline, colchicine, and topical sodium thiosulfate, along with others. Recommendations for the diagnosis and therapy of calcinosis cutis in patients with autoimmune connective tissue diseases are discussed.

Abstract
A candidate gene for TIMP-1 gene located on the X-chromosome (rs4898) was selected for a control case study to investigate a possible association of this SNP with the susceptibility to systemic sclerosis and its digit ulcer manifestation. A total of 461 individuals of Italian Caucasian origin (228 SSc patients and 233 healthy control subjects) were genotyped for TIMP-1 +372 T/C single nucleotide polymorphism rs4898. Subgroups were analyzed according to the presence or absence of digital ulcers. The CC genotype and C allele frequencies were significantly lower in female SSc patients than in controls (OR 0.53, CI 0.29-0.96, p=0.03 and OR 0.72, CI 0.53-0.98 p=0.04, respectively). CC genotypes frequency was lower also in female patients with ulcers than those without ulcers (OR 0.37, CI 0.14-1.00, p=0.03). Furthermore, CC genotype and C allele frequencies were lower also in female patients with ulcers in comparison to female healthy control subjects (OR 0.27, CI 0.10-0.70, p=0.004; OR 0.60, CI 0.40-0.89, p=0.01, respectively). The TIMP-1 rs4898 polymorphism may play a protective role in the susceptibility to SSC in females, and in particular to digital ulcer formation.

Abstract
Objective.We determined congruence with published guidelines from the European League Against Rheumatism (EULAR)/EULAR Scleroderma Trials and Research group, for systemic sclerosis (SSc) investigations and treatment practices within the Canadian Scleroderma Research Group (CSRG).Methods.Investigations and medication use for SSc complications were obtained from records of patients with SSc in the CSRG to determine adherence to guidelines for patients enrolled before and after the guidelines were published.Results.The CSRG database of 1253 patients had 992 patients with SSc enrolled before publication of the guidelines and 261 after. For pulmonary arterial hypertension (PAH) treatment, there were no differences in use before and after the guidelines, yet annual echocardiograms for PAH screening were done in 95% of patients enrolled before the guidelines and in only 86% of those enrolled after (p <0.0001), and fewer followup echocardiograms were done 1 year later in the latter group (88% vs 59%). No differences were found for the frequency of PAH-specific treatment; 60% had ever used calcium channel blockers for Raynaud’s phenomenon, with no differences in the groups before and after the guidelines. But the use of phosphodiesterase type 5 inhibitors (which does not have guidelines) was increased in the after-guidelines group. Proton pump inhibitors were used in > 80% with gastroesophageal reflux disease before and after the guidelines. One-quarter with gastrointestinal symptoms were taking prokinetic drugs. For those with past SSc renal crisis, use of angiotensin-converting enzyme inhibitors was not different before and after the guidelines. For early diffuse SSc < 2 years, ever-use of methotrexate was similar (one-quarter of each group); and for symptomatic interstitial lung disease, 19% had ever used cyclophosphamide before the guidelines and 9% after (p = nonsignificant). CSRG practices were generally comparable to recently published guidelines; however, use of iloprost and bosentan was low for digital ulcers because these drugs are not approved for use in Canada.Conclusion.There did not seem to be an increase in adherence to recommendations once the guidelines were published. For many guidelines, 25% to 40% of patients who would qualify received the recommended treatment.

Abstract
OBJECTIVE To determine the role of Class II HLAs in SSc patients from Italy and Spain and in SSc patients of Caucasian ancestry. METHODS Nine hundred and forty-four SSc patients (Italy 392 patients; Spain 452 patients) and 1320 ethnically matched healthy controls (Italy 398 patients; Spain 922 patients) were genotyped up to the fourth digit by PCR with sequence-specific oligonucleotides for HLA-DRB1, DQA1 and DQB1 loci. Patients included 390 ACA-positive and 254 anti-topo I-positive subjects. Associations between SSc or SSc-specific antibodies and HLA alleles or HLA haplotypes were sought via the chi-square test after 10 000-fold permutation testing. A meta-analysis including this study cohort and other Caucasoids samples was also conducted. RESULTS In both the cohorts, the strongest association was observed between the HLA-DRB1*1104 allele and SSc or anti-topo I antibodies. The HLA-DRB1*1104 -DQA1*0501 -DQB1*0301 haplotype was overrepresented in Italian [odds ratio (OR) = 2.069, 95% asymptotic CIs (CI(95)) 1.486, 2.881; P < 0.001] and in Spanish patients (OR = 6.707, CI(95) 3.974, 11.319; P < 0.001) as well as in anti-topo-positive patients: Italy (OR = 2.642, CI(95) 1.78, 3.924; P < 0.001) and Spain (OR = 20.625, CI(95) 11.536, 36.876; P < 0.001). In both the populations we also identified an additional risk allele (HLA-DQB1*03) and a protective allele (HLA-DQB1*0501) in anti-topo-positive patients. The meta-analysis showed different statistically significant associations, the most interesting being the differential association between HLA-DRB1*01 alleles and ACAs (OR = 1.724, CI(95) 1.482, 2.005; P < 0.001) or topo I antibodies (OR = 0.5, CI(95) 0.384, 0.651; P < 0.001). CONCLUSIONS We describe multiple robust associations between SSc and HLA Class II antigens in Caucasoids that may help to understand the genetic architecture of SSc.

Abstract
Calcinosis cutis is characterized by the deposition of insoluble calcium salts in the skin and subcutaneous tissue. The syndrome is separated into five subtypes: dystrophic calcification, metastatic calcification, idiopathic calcification, iatrogenic calcification, and calciphylaxis. Dystrophic calcification appears as a result of local tissue damage with normal calcium and phosphate levels in serum. Metastatic calcification is characterized by an abnormal calcium and/or phosphate metabolism, leading to the precipitation of calcium in cutaneous and subcutaneous tissue. Idiopathic calcification occurs without any underlying tissue damage or metabolic disorder. Skin calcification in iatrogenic calcinosis cutis is a side effect of therapy. Calciphylaxis presents with small vessel calcification mainly affecting blood vessels of the dermis or subcutaneous fat. Disturbances in calcium and phosphate metabolism and hyperparathyroidism can be observed.

Abstract
Objective.We studied a large clinical practice and multicenter database to estimate the minimally important difference (MID) in systemic sclerosis (SSc) using global rating of change anchors for the Health Assessment Questionnaire-Disability Index (HAQ-DI) and visual analog scale (VAS) in pain, fatigue, sleep, global status, and the Medical Outcomes Study Short-Form 36 (SF-36) in clinical practice.Methods.Longitudinal data were collected from a scleroderma clinic on patients with scleroderma (n = 109) who had completed the HAQ-DI and pain/fatigue/sleep/global status VAS (0 to 100 mm) questionnaires at 2 consecutive visits, and rated their change in overall status since the last visit as much better, better, same, worse, or much worse. Data were extracted from the Canadian Scleroderma Research Group (CSRG) database (n = 341) for 2 consecutive annual visits where the patients had completed HAQ-DI and SF-36, and the SF-36 “change in health” item.Results.For the single site, the mean baseline HAQ-DI was 0.895 and 0.911 at followup, with a mean change of 0.016. The MID estimates for improvement and worsening respectively were –0.0125 (0.125, 75th percentile)/0.042 (0.217, 75th percentile) for HAQ-DI, –8.00/3.61 for pain, –10.00/3.79 (25.32) for fatigue, –18.50/5.92 for sleep, and –6.70/4.05 for global VAS. In the CSRG, baseline scores were 0.787 for HAQ-DI, 37.20 for the Physical Component Summary (PCS) of SF-36, and 48.57 for the Mental Component Summary (MCS). The MID estimates for improvement and worsening were –0.037 (0.250, 75th percentile)/0.140 (0.375, 75th percentile) for HAQ-DI, 2.18/–1.74 for PCS, and 1.33/–2.61 for MCS.Conclusion.This study provides MID estimates in SSc from 2 large databases for commonly used patient-reported outcomes in a clinical practice setting, which could differ from MID in trials.

A polymorphism in the human serotonin 5-HT2A receptor gene may protect against systemic sclerosis by reducing platelet aggregation. Arthritis Res Ther 2008; 10:R103.

Abstract
INTRODUCTION Platelet aggregation may contribute to the pathogenesis of systemic sclerosis: following activation, platelets release significant amounts of serotonin - which promotes vasoconstriction and fibrosis, and further enhances aggregation. The C+1354T polymorphism in the exonic region of the serotonin 2A receptor gene determining the His452Tyr substitution was associated with blunted intracellular responses after serotonin stimulation, and may have a role in susceptibility to scleroderma. METHODS One hundred and fifteen consecutive systemic sclerosis patients and 140 well-matched healthy control individuals were genotyped by sequence-specific primer-PCR for the His452Tyr substitution of the serotonin 2A receptor gene, and associations were sought with scleroderma and its main clinical features. The functional relevance of the His452Tyr substitution was also assessed by evaluating the aggregation of platelet-rich plasma from His452/His452 and His452/Tyr452 healthy individuals after stimulation with adenosine diphosphate +/- serotonin. RESULTS The T allele of the C+1354T polymorphism was underrepresented in scleroderma patients compared with control individuals (5.2% versus 12.4%, P < 0.001, chi-square test and 1,000-fold permutation test) and its carriage reduced the risk for systemic sclerosis (odds ratio = 0.39, 95% confidence interval = 0.19 to 0.85, P < 0.01). Platelets from His452/Tyr452 healthy subjects more weakly responded to serotonin stimulation compared with platelets from His452/His452 individuals (3.2 +/- 2.6-fold versus 9.6 +/- 8.6-fold increase in aggregation, P = 0.017 by Kolmogorov-Smirnov test and P = 0.003 after correction for baseline adenosine diphosphate-induced aggregation values). CONCLUSION The His452Tyr substitution may influence susceptibility to systemic sclerosis by altering platelet aggregation in response to serotonin.

Abstract
Interleukin-10 (IL-10) can favour the development of fibrosis by promoting a relative shift towards T helper 2 responses. Three single base pair substitutions in the 5' flanking region of the IL-10 gene (G/A -1082, C/T -819 and C/A -592) influence the amount of IL-10 secreted in cell cultures: the GCC haplotype is associated with an increased production, while the ACC and the ATA haplotypes are associated with intermediate and decreased production. Accordingly, three phenotypes have been individuated: high producers (GCC+/GCC+), medium producers (GCC+/GCC-) and low producers (GCC-/GCC-). We hypothesised that IL-10 haplotypes and genotypes are differently expressed in patients with systemic sclerosis (SSc) with the limited cutaneous SSc (lcSSc) subset or the diffuse cutaneous SSc (dcSSc) subset. One hundred and sixty-one unrelated Italian patients with SSc and 94 controls have been included. Their DNA was extracted and stored before being analysed by polymerase chain reaction with sequence-specific primers. The GCC haplotype is overrepresented in patients with SSc; subjects with dcSSc were the primary contributors to these results (dcSSc: 52.2% vs controls: 37.2%; chi2= 8.519, 2 d.f., corrected P= 0.04). In Scl70-positive patients, the GCC haplotype increased the likelihood of presenting the dcSSc subset [chi2= 12.56, P < 0.0005; odds ratio (OR) = 3.89, 95% confidence interval (CI(95)) = 1.69-9.08]; these results were confirmed at the phenotypic level (chi2= 11.67, 2 d.f., P= 0.003). In Scl70-positive patients, the high-producing phenotype was associated with poor survival, independently from disease subset and gender (hazard ratio = 9.9, CI(95)= 1.6-61.27, P < 0.05). The IL-10 haplotype and genotype associated with high IL-10 production may alter the susceptibility to SSc and/or its expression, increasing the prognostic value of other well-known markers of disease severity.

Abstract
This retrospective study evaluates the results of 41 consecutive hand and forearm operations in 19 patients with systemic sclerosis performed between 1985 and 2000. The mean age of the patients was 50 (14-84) years. Twenty-seven operations were elective and 14 were acute, carried out for skin breakdown and/or skin necrosis. One minor wound healing problem occurred in the elective group. In the acute group, seven of 14 operations healed uneventfully. Four patients had necrosis/infections after surgery, which required further surgery. Two patients had repeated wound infections. Another patient only healed after he stopped smoking. In systemic sclerosis, surgery performed electively does not seem to have increased difficulty with wound healing. Even larger operations, such as wrist arthrodesis or wrist replacement, can be performed safely. In acute cases with spontaneous skin breakdown and/or necrosis and/or critically ischaemic fingers, wound healing is more precarious and several procedures may be necessary to achieve skin healing.

Abstract
Lung involvement constitutes nowadays the major cause of morbidity and mortality in scleroderma patients. Pulmonary fibrosis in systemic sclerosis (SSc) is thought to be the consequence of interstitial inflammation. Early diagnosis and treatment of active alveolitis is essential to prevent the deterioration of pulmonary function, improving outcome in SSc patients. The aim of the study was to investigate the effect of 1-year treatment with oral cyclophosphamide (CYC) on the evolution of interstitial lung disease in scleroderma patients with a diagnosis of active alveolitis. An open-label one-arm monocenteric study was conducted on 33 scleroderma patients with active alveolitis--defined as the presence of areas of 'ground-glass attenuation' on high-resolution computed tomography and a recent deterioration in lung function-treated with oral CYC 2 mg kg-1 day-1 for 1 year and medium-low dose steroids (prednisone 25 mg for 3 months and then tapered to 5 mg/day). Results showed that diffusing capacity for carbon monoxide (DLco) values remained stable after 6 months of treatment and significantly increased after 12 months (2.06+/-1.38, 2.21+/-1.62 and 2.39+/-1.64 mmol/min/kPa, at baseline/6/12 months, respectively; p<0.001 12th month vs baseline) vital capacity (VC) values slightly increased (i.e. stabilised) in the same time frame (2.46+/-0.71, 2.41+/-0.76 and 2.56+/-0.75 l). Accordingly, the vast majority of our patients (n=29, 87.9%) presented a DLco and/or a VC improvement or stabilisation with respect to baseline. Favourable results were more likely to be observed in patients with a lower Wells' radiological grade (grade I). In 25 patients followed up for further 12 months after the interruption of therapy, VC and DLco remained stable. Thus, long-term therapy with oral CYC is effective in ameliorating and/or stabilising lung function in scleroderma patients with active alveolitis, with beneficial effects lasting up to 1 year after interruption. The higher efficacy in those patients with an early pulmonary disease stage and a lower radiological grade underlies the importance of an early diagnosis and intervention.

Abstract
OBJECTIVES To evaluate the clinical efficacy and the effects on the quality of life of iloprost, a prostacyclin analogue, used according to a new protocol in patients with Raynaud's phenomenon secondary to systemic sclerosis. METHODS In this randomized study, we treated 30 patients with iloprost, given by intravenous infusion, at progressively increasing doses (from 0.5 to 2 ng/kg/min) over a period of 6 h each day for 10 days in two consecutive weeks, with repeated cycles at regular intervals of 3 months for 18 months. The results were compared with those obtained in 30 other patients who received the same drug but with different dosing schemes. RESULTS The total average daily duration of the attacks, the average duration of a single attack and the average daily frequency of the attacks were reduced significantly in all treatment groups, but the comparison between the groups demonstrated significant differences between patients treated with the new protocol and the others at later times (12 and 18 months). The effects on the quality of life in the group treated with the new protocol, evaluated with the Short Form-36, demonstrated a marked improvement regarding both the scale relating to the physical aspect of the illness and, especially, the scale relating to the mental aspect. CONCLUSIONS In patients with systemic sclerosis, cyclic intravenous iloprost infusion is efficacious in the treatment of Raynaud's phenomenon. The protocol that we used, compared with others, not only has favourable clinical effects but also leads to a marked improvement in the quality of life.

Abstract
BACKGROUND Anticentromere antibodies are characteristically observed in scleroderma but have recently been reported in other autoimmune rheumatic disorders, including Sjögren's syndrome. It is not known whether distinct centromere proteins (CENP) are targeted in primary Sjögren's syndrome (pSS) and scleroderma. OBJECTIVE To determine whether antibodies to CENP-B and CENP-C are present in these two disorders. METHODS Sera from 45 patients with pSS and 33 with limited scleroderma were studied. All patients met classification criteria for pSS and scleroderma, respectively. Sera were used to immunoprecipitate in vitro translated CENP-B and CENP-C. The proportions recognising CENP-B or CENP-C were compared. RESULTS 10 of 45 patients (22%) with pSS and 18 of 33 (55%) with scleroderma had antibodies recognising CENPs (p = 0.004). Seven of 10 (70%) CENP positive patients with pSS recognised CENP-C alone, compared with one of 18 (6%) CENP positive patients with scleroderma (odds ratio (OR) = 40 (95% confidence interval (CI), 3.5 to 450) (p = 0.003). In contrast, the majority (15 of 18 (83%)) of CENP positive scleroderma sera recognised both CENP-B and CENP-C, compared with none of 10 pSS sera (OR = 93 (95% CI, 4.4 to 1979) (p = 0.0001). CONCLUSIONS The pattern of CENP recognition differs markedly in pSS and limited scleroderma. While patients with pSS predominantly recognise CENP-C alone, dual recognition of CENP-B and CENP-C is most frequent in scleroderma. These findings suggest that obtaining antibodies to specific centromere antigens is useful diagnostically, and imply that distinct mechanisms underlie the unique patterns of centromere autoreactivity in pSS and scleroderma.

Abstract
In scleroderma patients, isolated pulmonary hypertension (PHT) has been associated with selected HLA haplotypes, severe impairment of the diffusing capacity for carbon monoxide and the diagnosis of CREST. Most patients with CREST have a late-age onset of the disease, corresponding to the perimenopausal or postmenopausal period. We conducted a retrospective cohort study to determine the role of post-menopause and of the other known clinical and biological markers in the development of isolated pulmonary hypertension in Italian patients with systemic sclerosis. 189 female patients with scleroderma who had no ecographic signs of pulmonary hypertension (PHT) and radiographic signs of lung fibrosis at the first visit and did not develop significant pulmonary fibrosis during the observation time were included. Sixty-three out of 189 patients (33.3%) presented isolated pulmonary hypertension. A severe impairment of diffusing capacity for carbon monoxide at admission was found to be an early predictive element for its development. An increased risk was associated with postmenopausal condition (RR = 5.2, p = 0.000), CREST syndrome (RR = 2.8, p = 0.001) and haplotype HLA-B35 (RR = 2.8; p = 0.002). A significant positive interaction between postmenopausal condition and either HLA-B35 (RR = 15.2; p = 0.000) or the diagnosis of CREST (RR = 14.1; p = 0.000) was found. Postmenopausal condition alone or in combination with HLA-B35 and CREST syndrome is the main risk-factor for developing primary pulmonary hypertension in scleroderma patients. This suggests that hormonal replacement therapy could play a role in preventing isolated PHT in patients with systemic sclerosis.

Abstract
Epidemics of vascular disease caused by toxins and infectious agents affecting both humans and animals have been common in history. Examples of agents implicated include anorexients, ergotamine, mercury, arsenic, vinyl chloride, thorotrast, plant alkaloids, nitrites, toxic oil, tryptophan and bacterial, viral and parasitic infections. A major characteristic of these disorders is endothelial dysfunction, which may manifest itself in vasospastic disorders, sclerodermiform skin lesions, fibrosis, osteolytic lesions, polyneuropathy and portal and pulmonary hypertension. Angiosarcoma may also be a late outcome. These diseases are more common than is generally appreciated. The aetiology is usually multifactorial. This and other factors contribute to delayed recognition.

Abstract
OBJECTIVE The aim of this study was to investigate the relationship between esophageal dysfunction and pulmonary involvement in patients with systemic sclerosis (SSc). METHODS Pulmonary function parameters were compared between groups of patients with and without manometric evidence for SSc-induced esophageal dysmotility. RESULTS Twenty-six of 43 patients (60.5%) exhibited a marked hypo- or aperistalsis of the smooth muscle portion of the esophagus. Total lung capacity, inspiratory vital capacity, and forced vital capacity were significantly lower in patients with esophageal dysfunction compared with those with normal esophageal peristalsis (p < 0.001). Patients with the diffuse form of SSc (n = 20) had significantly lower values for total lung capacity and inspiratory vital capacity compared with patients with the limited type of SSc (n = 23; p < 0.05). CONCLUSION There is a significant association of esophageal dysmotility with reduced lung volumes in SSc. Possible explanations for these findings are pulmonary damage due to increased gastroesophageal reflux and, more likely, simultaneous involvement of the lungs and the esophagus in the disease process.

Abstract
OBJECTIVE To investigate the relationship between esophageal function and the extent of disease in a nonselected group of scleroderma patients, and to study gastric and small bowel motility in a group of scleroderma patients with more severe clinical manifestations. METHODS Esophageal function in 125 scleroderma patients was investigated by radiologic, endoscopic, manometric, and pH-metric techniques. Ten patients also underwent gastrointestinal (GI) manometric recording, both during fasting and after a standard meal. RESULTS Radiologic abnormalities of the esophagus were found in 55 of 81 patients (68%) and esophagitis in 45 of 125 (36%). No significant relationship was disclosed between GI symptoms, radiologic abnormalities, esophagitis grade, and the various disease subsets. However, the overall incidence of endoscopic esophagitis (irrespective of the degree) was significantly (P < 0.05) correlated with the patient subgroups, with 100% incidence of esophagitis in those having the more severe cutaneous involvement (type III). Manometric abnormalities were documented in 80% of patients, and pathologic reflux in 78%. The severity of esophageal abnormalities on manometry significantly correlated with the severity of the disease, whereas no correlations were found with pH-metric data. Ninety percent of the 10 female patients undergoing antroduodenal manometry displayed abnormal findings; of these, 60% showed neuropathic, and 30% myopathic, patterns. The latter were recorded in patients with a more severe stage of the disease (type III). CONCLUSION A direct relationship was observed between scleroderma subsets and the severity of esophageal (and, probably, more distal gut) motor involvement. Since no correlation was found between esophageal symptoms and the severity of manometric abnormalities, manometry should be considered the single most important GI test to document the severity of the "esophageal" disease. Gastric and small bowel manometry may also offer evidence of widespread gut involvement, and provide a rationale for a more targeted therapeutic approach.

Abstract
BACKGROUND Docetaxel (Taxotere) is a microtubule-stabilizing agent that is potentially important in chemotherapy for a variety of malignancies. METHODS A clinical study of the cutaneous reactions experienced by a group of patients receiving docetaxel chemotherapy was undertaken. Patients were examined before initiation of therapy, before and after each cycle of therapy, and were followed subsequent to the completion of docetaxel chemotherapy. RESULTS Three patients developed diffuse lower extremity edema (3-18 kg) and subsequent scleroderma-like changes after receiving multiple cycles of docetaxel therapy. These patients had different underlying malignancies and dissimilar prior therapy. Rheumatoid factor, antinuclear antibodies, anticentromere, and topoisomerase antibodies were not present in any patient. The diffuse lower extremity edema did not resolve with diuretic therapy. Cutaneous biopsies in two patients revealed diffuse sclerosis. One patient had a normal lymphangiogram during the edematous phase. Discontinuation of docetaxel correlated with resolution of edema and softening of the skin. CONCLUSION The etiology of the scleroderma-like skin changes is unclear but appears to be either a toxic effect of docetaxel or an effect of polysorbate 80 (Tween 80), the vehicle for docetaxel.

Abstract
After the skin, the gastrointestinal tract is the second most common target of systemic sclerosis. The major clinical manifestations include gastroesophageal reflux, small bowel bacterial overgrowth, malnutrition, and intestinal pseudoobstruction. Treatment is symptomatic and supportive. Gastroesophageal reflux can usually be adequately managed with prokinetic drugs, omeprazole, and judicious use of antireflux surgery. If Barrett's esophagus is present, periodic endoscopic monitoring for development of dysplastic changes or adenocarcinoma is indicated. Bacterial overgrowth usually responds to rotating antibiotics and prokinetic drugs. Malnutrition and intestinal pseudoobstruction remain the major problems and often home total parenteral nutrition is required. Intestinal pseudoobstruction occurs in two phases: an early, neuropathic phase may respond to prokinetic drugs (metoclopramide, cisapride, octreotide, and erythromycin) and dietary modification (low-residue diets, vitamin supplementation). In the late myopathic phase, therapy is usually ineffective. Treatment consists of nutritional support. Careful manometric and radiographic localization of affected segments of stomach and small and large intestines may allow judicious surgical resection or venting procedures to reduce symptoms in this unfortunate group of patients.
