    Full Text Available The mechanisms underlying endothelial cell injury and defective vascular repair in systemic sclerosis (SSc remain unclear. Since the recently discovered angiogenic T cells (Tang may have an important role in the repair of damaged endothelium, this study aimed to analyze the Tang population in relation to disease-related peripheral vascular features in SSc patients. Tang (CD3+CD31+CXCR4+ were quantified by flow cytometry in peripheral blood samples from 39 SSc patients and 18 healthy controls (HC. Circulating levels of the CXCR4 ligand stromal cell-derived factor (SDF-1α and proangiogenic factors were assessed in paired serum samples by immunoassay. Serial skin sections from SSc patients and HC were subjected to CD3/CD31 and CD3/CXCR4 double immunofluorescence. Circulating Tang were significantly increased in SSc patients with digital ulcers (DU compared either with SSc patients without DU or with HC. Tang levels were significantly higher in SSc patients with late nailfold videocapillaroscopy (NVC pattern than in those with early/active NVC patterns and in HC. No difference in circulating Tang was found when comparing either SSc patients without DU or patients with early/active NVC patterns and HC. In SSc peripheral blood, Tang percentage was inversely correlated to levels of SDF-1α and CD34+CD133+VEGFR-2+ endothelial progenitor cells (EPC, and positively correlated to levels of vascular endothelial growth factor and matrix metalloproteinase-9. Tang were frequently detected in SSc dermal perivascular inflammatory infiltrates. In summary, our findings demonstrate for the first time that Tang cells are selectively expanded in the circulation of SSc patients displaying severe peripheral vascular complications like DU. In SSc, Tang may represent a potentially useful biomarker reflecting peripheral vascular damage severity. Tang expansion may be an ineffective attempt to compensate the need for increased angiogenesis and EPC function. Further

    Systemic sclerosis (SSc, or scleroderma) is a rheumatic disease with distinct features that encompass autoimmunity, vascular lesions (vasculopathy) and tissue fibrosis. The disease has a high morbidity and mortality compared with other rheumatic diseases. This review discusses risk factors and markers that predict the disease course and the occurrence of disease manifestations, with an emphasis on major organ involvement. In addition, risk factors will be described that are associated with mortality in SSc patients. The review addresses the impact of recent developments on screening, diagnosis and risk stratification as well as the need for further research where data are lacking.

    We aimed to assess the clinical significance of Krebs von den Lungen-6 (KL-6) in the diagnosis and severity of interstitial lung disease (ILD) in a French cohort of patients with systemic sclerosis (SSc). Serum KL-6 concentrations were measured with chemiluminescent enzyme immunoassay (CLEIA) in 75 SSc patients. Patients were divided into two groups according to the presence of interstitial lung disease (SSc-ILD versus SSc-without ILD) on chest High-Resolution Computed Tomography. Pulmonary function tests, main manifestations and severity of the lung disease (Medsger's severity scale) were collected. KL-6 serum concentrations were significantly higher in SSc-ILD patients than in those without ILD (p < 10 -4 ) and were inversely correlated with forced vital capacity, total lung capacity and diffuse lung capacity of carbon monoxide. Serum KL-6 level superior to 872 U/ml appeared as the optimal cut-off value associated with ILD. Patients with a restrictive pulmonary syndrome and dyspnoea had significant higher KL-6 serum concentrations. SSc patients with anti-topoisomerase 1 antibodies had higher KL-6 serum levels than patients with anti-centromere antibodies (p < 10 - 4 ). ILD and anti-topoisomerase 1 antibodies were independent factors associated with KL-6 in multivariate analysis. Interestingly, KL-6 serum concentrations positively increased with the patient lung severity. Our study confirms that KL-6 is an accurate biomarker for the diagnosis of SSc-ILD in a French cohort of patients. High KL-6 levels should prompt physicians to assess ILD with pulmonary imaging and pulmonary functions tests. Prospective clinical studies are still required to determine whether levels of KL-6 might predict progression of ILD as well as its usefulness in the timing of therapeutic intervention.

    2013-05-01

    Systemic sclerosis is a connective tissue disease characterised by microvascular injury and excessive fibrosis of the skin and internal organs. Most patients with this condition experience Raynaud phenomenon, usually as the earliest manifestation of disease. In addition to pain and functional impairment, Raynaud phenomenon can produce tissue ischaemia resulting in digital ulceration and gangrene. Current treatments have been only moderately successful in reducing the frequency and severity of Raynaud phenomenon in patients with systemic sclerosis. This review will address treatments available for Raynaud phenomenon in systemic sclerosis. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

    Several occupational hazards, especially exposure to silica, have been implicated as causal factors for the development of scleroderma-like disorders. Compared to other connective tissue disorders, silica-associated systemic sclerosis (SA-SS) is relatively rare. Silica-induced scleroderma is indistinguishable from idiopathic systemic sclerosis. However, the former expresses a high predisposition of pulmonary involvement and anti-Scl-70 antibody. We report the case of a 42-year-old male, stone cutter by occupation, who was diagnosed as simple chronic silicosis and developed systemic sclerosis.

    The aim of this study was to analyze the correlation of vitamin D levels with clinical parameters, bone mineral density (BMD), quality of life (QoL) and nailfold capillaroscopy (NC) in patients with diffuse systemic sclerosis (SSc). Thirty-eight female patients with diffuse SSc were analyzed regarding 25-hydroxyvitamin D (25OHD) serum levels. At inclusion, organ involvement, autoantibodies, modified Rodnan skin score (mRSS), Medsger Disease Severity Index (MDSI), body mass index (BMI), BMD, NC, Short-Form-36 Questionnaire (SF-36), and Health Assessment Questionnaire (HAQ), were performed through a standardized interview, physical examination and electronic chart review. Mean 25OHD serum level was 20.66±8.20ng/mL. Eleven percent of the patients had 25OHD levels ≤10ng/mL, 50% ≤20ng/mL and 87% ≤30ng/mL. Vitamin D serum levels were positively correlated with BMI (r=0.338, p=0.038), BMD-total femur (r=0.340, p=0.037), BMD-femoral neck (r=0.384, p=0.017), SF-36-Vitality (r=0.385, p=0.017), SF-36-Social Function (r=0.320, p=0.050), SF-36-Emotional Role (r=0.321, p=0.049) and SF-36-Mental Health (r=0.531, p=0.0006) and were negatively correlated with HAQ-Reach (r=-0.328, p=0.044) and HAQ-Grip Strength (r=-0.331, p=0.042). A negative correlation with NC-diffuse devascularization (p=0.029) and NC-avascular area (p=0.033) was also observed. The present study provides novel evidence demonstrating that low levels of 25OHD have a negative impact in diffuse SSc QoL and further studies are needed to define whether vitamin D supplementation can improve health related QoL in these patients. The additional observation of a correlation with severe NC alterations suggests a possible role of 25OHD in the underlying SSc vascular involvement. Copyright © 2016 Elsevier Editora Ltda.

    Full Text Available Objective: the aim of the study was to investigate the relationship between Systemic Sclerosis (SSc and HLA antigens, and to correlate these antigens with the clinical manifestations of the disease. Materials and methods: 55 patients were stratified according a to the cutaneous involvement b to the positivity of Scl- 70 and anticentromere antibody and c to the internal organ involvement, in particular we used HRCT to demonstrate lung fibrosis, echocardiography for the diagnosis of pulmonary hypertension, blood creatinine, urinalysis and arterial hypertension to demonstrate renal failure, and esophagus double-countrast barium swallow for the diagnosis of esophagopathy. The control group consisting of 2000 healthy Caucasian subjects was recruited from the same population. Results: the frequency of the antigens A23 (p=0.003, RR=3.69, B18 (p<0.0001, RR=3.57, and DR11 (p<0.0001, RR=6.18 was statistically increased in the patients population compared with the healthy controls. Although there is no any significant correlation between HLA antigens and different clinical subsets of scleroderma, antigens B18 and DR11 could be associated with more severe clinical features. Conclusions: the presence of a significant association between SSc and specific HLA antigens (A23, B18, and DR11 could link the HLA system with SSc.

    Multiple sclerosis (MS) and Systemic Lupus Erythematosus (SLE) with/without antiphospholipid syndrome are autoimmune illnesses. It has been described in many occasions the association of these two illnesses and the clinical picture of MS with characteristics of laboratory of SLE. When they affect to the central nervous system they can make it in a defined form for each illness or they can also make it in interposed or combined form of the two illnesses what has been called lupoid sclerosis; making that in some cases difficult the differentiation of the two illnesses and therefore to address the treatment. We present four cases of lupoid sclerosis, discuss the clinical and laboratory characteristics of this entity and we make a differentiation of the multiple sclerosis with the neurological affectation of SLE especially for images and laboratory results.

    Interstitial lung disease (ILD) is a frequent complication in progressive systemic sclerosis (SSc), being present in 25% to 90% of cases. To evaluate whether serum levels of procollagen typei and iii aminoterminal propeptide (PINP and PIIINP) correlate with severity and patterns of ILD in Mexican women with SSc. Thirty three SSc patients were assessed for disease characteristics and anti-topoisomerase antibodies (topoi), and also underwent pulmonary function tests and high-resolution computed tomography (HRCT). Nineteen patients had ILD+SSc, and 14 had no lung involvement (no ILD-SSc); data were compared with those from 45 healthy controls. PINP and PIIINP were assessed in all 3 groups. Patients with SSc had higher PINP and PIIINP vs controls (P=.001, Ptopoi U/mL (Ptopoi (P=.045). PINP and PIIINP are useful markers for severe ILD+SSc, suggesting they could play a role in the follow-up of this complication in SSc. Copyright © 2014 SEPAR. Published by Elsevier Espana.

  15. Esophageal transit scintigraphy in systemic sclerosis

    2016-11-01

    Full Text Available Systemic sclerosis is a rare connective tissue disease, distinctive features of which are fibrosis and microangiopathy. The esophagus is one of the most commonly involved internal organs. Most patients experience dysphagia, difficulties in swallowing and gastro-esophageal reflux. However, in up to one third of cases, the initial onset of esophageal disease may be clinically silent. There are several diagnostic modalities available for assessing both morphological and functional abnormalities of the esophagus. If structural abnormalities are suspected, endoscopy is the method of choice. Functional evaluation is best achieved with manometry. Both endoscopy and manometry are invasive techniques, with low patient acceptance. Barium-contrast study is well tolerated, but qualitative assessment of functional abnormalities is imprecise. Esophageal scintigraphy is an easy, non-invasive, sensitive and specific diagnostic modality. It can detect esophageal dysfunction even in asymptomatic patients. In patients already diagnosed with systemic sclerosis, scintigraphy is useful in evaluating severity and progression of the disease.

    Systemic sclerosis is a multisystem disease where functional and structural abnormalities of small blood vessels prevail. Recently, transient ischemic attacks, ischemic stroke, and hemorrhages have been reported as primary consequence of vascular central nervous system affection in systemic sclerosis. Magnetic resonance imaging (MRI) is considered to be the most sensitive diagnostic technique for detecting symptomatic and asymptomatic lesions in the brain in cases of multifocal diseases. Evaluate brain changes in patients with systemic sclerosis using MRI. Thirty female patients with systemic sclerosis aged 27-61 years, with disease duration of 1-9 years and with no history of other systemic disease or cerebrovascular accidents, were enrolled. An age-matched female control group of 30 clinically normal subjects, underwent brain MR examination. Central nervous system involvement in the form of white matter hyperintense foci of variable sizes were found in significantly abundant forms in systemic sclerosis patients on MR evaluation than in the age-related control group, signifying a form of central nervous system vasculopathy. Such foci showed no definite correlation with disease duration, yet they showed significant correlation to severity of peripheral vascular disease, headaches, fainting attacks and depression in the group under study. Asymptomatic as well as symptomatic central nervous system ischemic vasculopathy is not uncommon in systemic sclerosis patients and MRI is considered a sensitive noninvasive screening tool for early detection of CNS involvement in patients with systemic sclerosis.

To determine the prevalence of lactose malabsorption, using lactose breath test, in patients with SSc. To evaluate the correlation between lactose malabsorption and gastrointestinal involvement. To predict which SSc patients exhibit lactose malabsorption. Seventy-seven consecutive Caucasian patients with SSc and 20 control subjects underwent lactose breath test. All patients also completed a questionnaire on digestive symptoms, and a global symptom score (GSS) was calculated. The prevalence of lactose malabsorption was higher in SSc patients than in controls (44.3% vs. 10%; P = 0.004). We observed a marked correlation between the presence of lactose malabsorption and: higher values of GSS (P lactose malabsorption, the median value of GSS of digestive symptoms was lower after initiation of lactose-free diet (P lactose malabsorption often occurs in patients with systemic sclerosis. Furthermore, our findings highlight the fact that lactose breath test is a helpful, noninvasive method, by identifying the group of patients with systemic sclerosis with symptomatic lactose malabsorption that may benefit from a reduction in lactose intake. © 2016 John Wiley & Sons Ltd.

  20. Modeling disease severity in multiple sclerosis using electronic health records.

    Directory of Open Access Journals (Sweden)

    Zongqi Xia

    Full Text Available To optimally leverage the scalability and unique features of the electronic health records (EHR for research that would ultimately improve patient care, we need to accurately identify patients and extract clinically meaningful measures. Using multiple sclerosis (MS as a proof of principle, we showcased how to leverage routinely collected EHR data to identify patients with a complex neurological disorder and derive an important surrogate measure of disease severity heretofore only available in research settings.In a cross-sectional observational study, 5,495 MS patients were identified from the EHR systems of two major referral hospitals using an algorithm that includes codified and narrative information extracted using natural language processing. In the subset of patients who receive neurological care at a MS Center where disease measures have been collected, we used routinely collected EHR data to extract two aggregate indicators of MS severity of clinical relevance multiple sclerosis severity score (MSSS and brain parenchymal fraction (BPF, a measure of whole brain volume.The EHR algorithm that identifies MS patients has an area under the curve of 0.958, 83% sensitivity, 92% positive predictive value, and 89% negative predictive value when a 95% specificity threshold is used. The correlation between EHR-derived and true MSSS has a mean R(2 = 0.38±0.05, and that between EHR-derived and true BPF has a mean R(2 = 0.22±0.08. To illustrate its clinical relevance, derived MSSS captures the expected difference in disease severity between relapsing-remitting and progressive MS patients after adjusting for sex, age of symptom onset and disease duration (p = 1.56×10(-12.Incorporation of sophisticated codified and narrative EHR data accurately identifies MS patients and provides estimation of a well-accepted indicator of MS severity that is widely used in research settings but not part of the routine medical records.

    Introduction: systemic sclerosis is an autoimmune disease characterized by endothelial damage, and skin, vessel and internal organ fibrosis and inflammation. There are differences in terms of frequency, severity and prognosis for the different ethnic groups, what reinforces the importance of the study in each geographical region with the purpose of enabling early diagnosis of its incipient symptoms.Methods: we conducted a descriptive and retrospective study form March 2006 through March 2008, including patients with a final diagnosis of systemic sclerosis, who are treated at the Systemic Autoimmune Diseases Unit at the Clinicas Hospital. Results: 31 women were included in the study, average follow-up of patients was 39.2 months, and average age at the time of diagnosis was 47.6 years. Eleven patients (35,5) presented diffuse disease and 20 (64.5) of them evidenced limited disease. Thirty patients presented Raynaud's phenomenon. In 92 of cases capilaroscopy showed a sclerodermiform pattern. In terms of the respiratory system, we found interstitial pathology in 25 of cases, pulmonary arterial hypertension in 22.2 and are restrictive pattern in respiratory function studies in 35.5. Also, 67.7 presented digestive manifestations and 9.6 developed sclerodermic renal crisis. We found anti-nuclear antibodies (ANA) in 29 out of 31 patients (93,5) patients; 16 presented anticentromere antibodies and five anti-topoisomerasa-I antibodies. The four patients (12.9)who died during follow-up presented common elements such as diffuse sclerosis, digital ulcers and severe respiratory compromise. Conclusions: the clinical and immune characteristics found in our study were similar to those described in other series. Should there be no specific treatment, it is essential to perform regular assessment of visceral impact in order to control and delay complications which result in high morbimortality rates.

    Full Text Available Systemic sclerosis (SS is a systemic disease, the basis for which is microcirculatory disorders, inflammation, and generalized fibrosis. Interstitial lung disease (ILD is one of the primary manifestations of SS. Assessment of SS activity and severity is hindered as it is very difficult to differentiate fibrous and inflammatory changes that are mostly interrelated and have a similar picture.Objective: to estimate activity index (AI and total severity index (TSI for the follow-up of SS patients with different variants of ILD. Subjects and methods. The investigation enrolled 77 patients with SS and ILD, who were followed up at the V.A. Nasonova Research Institute of Rheumatology; their mean age at inclusion was 46±13 years. All the patients underwent high-resolution computed tomography (HRCT of the chest and determination of TSI and AI scores at baseline and after an average of 59±12 months. According to the time course of HRCT revealed pulmonary changes over a 5-year follow-up, the patients were divided into 3 groups: 1 patients with improvement (n=16; 2 those without changes (n=39; 3 those with deterioration (n=22.

    2016-02-01

    Full Text Available Aim To examine the presence of depressive symptoms in patients with multiple sclerosis relapse and its relation to disability and relapse severity. Methods This study included 120 patients who were assessed during the acute relapse of multiple sclerosis according to Mc Donald criteria. Depression was assessed using Beck Depression Inventory II (BDI-II calculating both affective and somatic symptom scores. The Expanded Disability Status Scale (EDSS measured disability. Relapse severity was graded according to the difference between the EDSS score during relapse and EDSS score before the onset of the attack as mild, moderate or severe. Results There was statistically significant difference between patients with different level of depression considering age (p<0.001, disability (p<0.001, relapse severity (p=0.005 and disease duration (p=0.032. Significant moderate positive correlation of depression with age (rho=0.43 and disability (rho=0.46 was confirmed. There was moderate correlation between disability and somatic symptoms of depression (rho=0.54, p<0.001 with only weak correlation between disability and affective symptoms of depression (rho=0.31, p<0.01. Multiple regression analysis showed that patient’s age and relapse severity (p<0.05 were independently related to depression in these patients while disability did not. Conclusion Correlation between disability and depression was mostly due to somatic symptoms of depression. Although highly correlated, depression during multiple sclerosis relapse was not independently predicted by disability. Depression should be recognized and treated independently from disability treatment, especially in the group of older patients with more severe relapse.

    Full Text Available Targeted therapies use an understanding of the pathophysiology of a disease in an individual patient. Although targeted therapy for systemic sclerosis (SSc, scleroderma has not yet reached the level of patient-specific treatments, recent developments in the understanding of the global pathophysiology of the disease have led to new treatments based on the cells and pathways that have been shown to be involved in the disease pathogenesis. The presence of a B cell signature in skin biopsies has led to the trial of rituximab, an anti-CD20 antibody, in SSc. The well-known properties of transforming growth factor (TGF-β in promoting collagen synthesis and secretion has led to a small trial of fresolimumab, a human IgG4 monoclonal antibody capable of neutralizing TGF-β. Evidence supporting important roles for interleukin-6 in the pathogenesis of SSc have led to a large trial of tocilizumab in SSc. Soluble guanylate cyclase (sGC is an enzyme that catalyzes the production of cyclic guanosine monophosphate (cGMP upon binding of nitric oxide (NO to the sGC molecule. Processes such as cell growth and proliferation are regulated by cGMP. Evidence that sGC may play a role in SSc has led to a trial of riociguat, a molecule that sensitizes sGC to endogenous NO. Tyrosine kinases (TKs are involved in a wide variety of physiologic and pathological processes including vascular remodeling and fibrogenesis such as occurs in SSc. This has led to a trial of nintedanib, a next-generation tyrosine-kinase (TK inhibitor which targets multiple TKs, in SSc.

    Full Text Available Systemic sclerosis is a chronic connective tissue disease characterized by microvascular abnormalities, immune disturbances and progressive fibrosis of the skin and internal organs. Skin involvement may result in contractures, leading to marked loss of hand mobility, adversely affecting the performance of daily activities and decreasing the quality of life. Face involvement not only causes functional loss, but also lowers the self-esteem of patients. Increasing attention has recently been focused on the need to rehabilitate patients with systemic sclerosis in order to prevent the development of joint contractures and loss of mobility. The study presents a review of the current literature on rehabilitation possibilities in patients with systemic sclerosis, with a special focus on physiotherapy methods.

    The deleterious effect of fructose, which is increasingly incorporated in many beverages, dairy products, and processed foods, has been described; fructose malabsorption has thus been reported in up to 2.4% of healthy subjects, leading to digestive clinical symptoms (eg, pain, distension, diarrhea). Because digestive involvement is frequent in patients with systemic sclerosis (SSc), we hypothesized that fructose malabsorption could be responsible for intestinal manifestations in these patients. The aims of this prospective study were to: determine the prevalence of fructose malabsorption, in SSc; predict which SSc patients are at risk of developing fructose malabsorption; and assess the outcome of digestive symptoms in SSc patients after initiation of standardized low-fructose diet. Eighty consecutive patients with SSc underwent fructose breath test. All SSc patients also completed a questionnaire on digestive symptoms, and a global symptom score (GSS) was calculated. The prevalence of fructose malabsorption was as high as 40% in SSc patients. We also observed a marked correlation between the presence of fructose malabsorption and: higher values of GSS score of digestive symptoms (P = 0.000004); and absence of delayed gastric emptying (P = 0.007). Furthermore, in SSc patients with fructose malabsorption, the median value of GSS score of digestive symptoms was lower after initiation of standardized low-fructose diet (4 before vs. 1 after; P = 0.0009). Our study underscores that fructose malabsorption often occurs in SSc patients. Our findings are thus relevant for clinical practice, highlighting that fructose breath test is a helpful, noninvasive method by: demonstrating fructose intolerance in patients with SSc; and identifying the group of SSc patients with fructose intolerance who may benefit from low-fructose diet. Interestingly, because the present series also shows that low-fructose diet resulted in a marked decrease of gastrointestinal clinical manifestations

    2010-01-01

    Full Text Available Systemic sclerosis (SSc is a chronic autoimmune disorder characterized by progressive fibrosis of the skin and visceral tissues as well as a noninflammatory vasculopathy. Vascular disease in systemic sclerosis is a major cause of morbidity and mortality among nonpregnant patients with SSc and is even a bigger concern in the pregnant SSc patient, as the underlying vasculopathy may prevent the required hemodynamic changes necessary to support a growing pregnancy. Vascular manifestations including scleroderma renal crisis and pulmonary arterial hypertension should be considered relative contraindications against pregnancy due to the high associations of both maternal and fetal morbidity and mortality. In contrast, Raynaud's phenomenon may actually improve somewhat during pregnancy. Women with SSc who are considering a pregnancy or discover they are pregnant require evaluation for the presence and extent of underlying vasculopathy. In the absence of significant visceral vasculopathy, most women with SSc can expect to have reasonable pregnancy outcomes.

    Primary sclerosing cholangitis is a chronic inflammatory fibrotic disorder strongly associated with inflammatory bowel disease. Although an association between some inflammatory fibrotic conditions, such as Riedel's thyroiditis and retroperitoneal fibrosis and primary sclerosing cholangitis has been described, to our knowledge there are no reports of primary sclerosing cholangitis in patients with systemic sclerosis. A patient with this combination of conditions is presented and the possible significance of the association discussed. Images Figure 1 Figure 2 PMID:2041852

    2014-12-01

    Full Text Available Systemic sclerosis (SSc is a multifactorial connective tissue disease characterized by excessive and progressive fibrosis along with microvasculopathy due to poor vascular formation and repair. Despite a general increase in many potent angiogenic factors, the vasculopathy compensatory angiogenesis and vasculogenesis are impaired. In this review, we discuss the role of proangiogenic factors – VEGF, PlGF, endoglin, PDGF, endothelin-1, angiopoietins, SDF-1, uPAR – and the paradoxical paucity of an inadequate angiogenic response in SSc.

    Lung transplantation can be a life-saving measure for people with end-stage lung disease from systemic sclerosis. However, outcomes of lung transplantation may be compromised by gastrointestinal manifestations of systemic sclerosis, which can involve any part of the gastrointestinal tract. Esophageal and gastric disease can be managed by enteral feeding with the use of a gastrojejunal feeding tube. In this report, we describe the clinical courses of 2 lung transplant recipients with systemic sclerosis who experienced severe and prolonged barium-impaction ileus after insertion of a percutaneous gastrojejunal feeding tube.

    2012-01-01

    Systemic sclerosis is a connective tissue disorder that affects multiple organs. Although the initial symptoms of the disease are vascular, skin involvement is almost universally present in patients with systemic sclerosis. The presence of Raynaud's phenomenon, progressive thickening of the skin, digital ulcers, and calcinosis all correlate proportionally with disease severity. Since no treatment is available to completely prevent the natural course of the disease, emphasis is often placed on managing symptoms and complications. In this review, the authors focus on the management of each one of the skin manifestations seen in systemic sclerosis, as the dermatologist may facilitate the early recognition and treatment of these complications.

    Systemic sclerosis is a multisystem autoimmune collagen disease where structural and functional abnormalities of small blood vessels prevail. Transient ischemic attacks, ischemic stroke, and hemorrhage have been reported as primary consequence of vascular central nervous system affection in systemic sclerosis. Magnetic resonance imaging is considered to be the most sensitive diagnostic technique for detecting symptomatic and asymptomatic lesions in the brain in cases of multifocal diseases. The objective of this study is to detect subclinical as well as clinically manifest cerebral vasculopathy in patients with systemic sclerosis using magnetic resonance imaging. As much as 30 female patients with systemic sclerosis aged 27-61 years old, with disease duration of 1-9 years and with no history of other systemic disease or cerebrovascular accidents, were enrolled. Age-matched female control group of 30 clinically normal subjects, underwent brain magnetic resonance examination. Central nervous system (CNS) involvement in the form of white matter hyperintense foci of variable sizes were found in significantly abundant forms in systemic sclerosis patients on magnetic resonance evaluation than in age-related control group, signifying a form of CNS vasculopathy. Such foci showed significant correlation to clinical features of organic CNS lesion including headaches, fainting attacks and organic depression as well as to the severity of peripheral vascular disease with insignificant correlation with disease duration. In conclusion, subclinical as well as clinically manifest CNS ischemic vasculopathy is not uncommon in systemic sclerosis patients and magnetic resonance imaging is considered a sensitive noninvasive screening tool for early detection of CNS involvement in patients with systemic sclerosis.

    2016-01-01

    Full Text Available Systemic sclerosis (SSc is an autoimmune disorder of unknown aetiology characterized by early impairment of the microvascular system. Nailfold microangiopathy and decreased peripheral blood perfusion are typical clinical aspects of SSc. The best method to evaluate vascular injury is nailfold videocapillaroscopy, which detects peripheral capillary morphology, and classifies and scores the abnormalities into different patterns of microangiopathy. Microangiopathy appears to be the best evaluable predictor of the disease development and has been observed to precede the other symptoms by many years. Peripheral blood perfusion is also impaired in SSc, and there are different methods to assess it: laser Doppler and laser speckle techniques, thermography and other emerging techniques.

    A series of 21 subjects (2 males and 19 females) affected with systemic sclerosis, was examined by small bowel (oral and intubation methods) and colon enema. The underlying process responsible for abnormalities in the small bowel and colon in systemic sclerosis is a variable and pacthy destruction of the muscularis propria, that produces the structural and functional changes detected on X-ray: Pathologic condition is the same affecting the esophagus. The scout film of the abdomen often reveals colonic distension and fecal impaction, so that it may be quite difficult to prepare adequately the patients for a barium enema. Peristalsis may be virtually absent in short segments, and transit time may be several time longer than that in normal patients. For these reasons, intestinal pseudo-obstruction may appear in systemic sclerosis. The observed radiographic changes are: 1) in the small bowel: a) dilatation of the gut, especially in its proximal portions (duodenum and jejunum), in which the valvulae conniventes are straightened, normal or thinned; b) presence of diverticula, 2-4 cm in diameter, with hemispherical shape without the neck-like opening into the bowel lumen; 2) in the colon, the characteristic finding is an increase in size of individual haustra, forming sacculations or pseudo-diverticula, usually on the antemesenteric border of the transverse colon, better demonstrated on post-evacuation film. Moreover, loss of colonic haustration is also observed associated to colonic elongation and dilatation

    Full Text Available Systemic sclerosis (SSc is an autoimmune connective tissue disease characterized by cutaneous and visceral fibrosis and widespread vascular pathology. Raynaud's phenomenon is one of the most common manifestations of SSc. It may lead to complications such as digital ulceration and infarction and its treatment remains elusive. We present the case of a female patient with severe digital ischemia secondary to SSc. Treatment using vasodilators and prostacyclin analogues was ineffective, but the patient experienced a remarkable response to bosentan, a dual endothelin receptor antagonist. This report suggests that endothelin antagonists may benefit patients with SSc and vasculopathy as a major feature of the disease, including limb ischemia.Esclerose sistêmica (SSc é uma doença auto-imune do tecido conjuntivo caracterizada por fibrose cutânea e visceral, além de vasculopatia difusa.Ofenômeno deRaynaud é uma das manifestações mais comuns da SSc, que pode levar a complicações como úlceras digitais e infarto. Seu tratamento ainda é indefinido. Apresentamos o caso de uma paciente com isquemia digital grave secundária a SSc. O tratamento incluindo vasodilatadores e análogos de prostaciclina foi ineficaz, mas a paciente apresentou excelente resposta ao bosentan, um antagonista de receptores de endotelina. Este relato sugere que antagonistas de endotelina podem beneficiar pacientes com SSc e vasculopatia como principal característica da doença, incluindo isquemia de extremidades.

    The approach to systemic sclerosis (SSc) has changed over the years with an increasing focus on the very early diagnosis of the disease. The terminology identifying patients in the early phase of SSc has been significantly confusing in the last three decades. The purpose of this article is to analyze how the concept of "very early SSc" has evolved over the years, which is the role of an early diagnosis and how early treat patients. Several attempts have been made over time, to create more sensitive and specific classification criteria to include the largest number of SSc patients, also in the earliest phase. An algorythm for the very early diagnosis of SSc was identified, diagnostic preliminary criteria proposed, and new 2013 ACR/EULAR SSc classification criteria published, including new items and adding emphasis to the vasculopathic manifestations. True biomarkers that could predict the disease evolution are still missing. Treat or not to treat patients in the earliest phases still remain a dilemma. For the moment, the only feasible clinical strategy in very early SSc remains a tight follow up program to detect in "real time" the early internal organ involvement which may allow an aggressive therapeutic agenda.

    CRISTIANE eKAYSER

    2015-04-01

    Full Text Available Systemic sclerosis (SSc is an autoimmune disease characterized by vascular abnormalities, and cutaneous and visceral fibrosis. Serum autoantibodies directed to multiple intracellular antigens are present in more than 95% of patients and are considered a hallmark of SSc. They are helpful biomarkers for the early diagnosis of SSc and are associated with distinctive clinical manifestations. With the advent of more sensitive, multiplexed immunoassays, new and old questions about the relevance of autoantibodies in SSc are emerging. In this review we discuss the clinical relevance of autoantibodies in SSc emphasizing the more recently published data. Moreover, we will summarize recent advances regarding the stability of SSc autoantibodies over the course of disease, whether they are mutually exclusive and their potential roles in the disease pathogenesis.

  9. The Vascular Microenvironment and Systemic Sclerosis

    Directory of Open Access Journals (Sweden)

    Tracy Frech

    2010-01-01

    Full Text Available The role of the vascular microenvironment in the pathogenesis Systemic Sclerosis (SSc is appreciated clinically as Raynaud's syndrome with capillary nail bed change. This manifestation of vasculopathy is used diagnostically in both limited and diffuse cutaneous subsets of SSc, and is thought to precede fibrosis. The degree of subsequent fibrosis may also be determined by the vascular microenvironment. This paper describes why the vascular microenvironment might determine the degree of end-organ damage that occurs in SSc, with a focus on vascular cell senescence, endothelial progenitor cells (EPC including multipotential mesenchymal stem cells (MSC, pericytes, and angiogenic monocytes. An explanation of the role of EPC, pericytes, and angiogenic monocytes is important to an understanding of SSc pathogenesis. An evolving understanding of the vascular microenvironment in SSc may allow directed treatment.

    2017-01-01

    Systemic sclerosis (SSc) is an autoimmune connective tissue disorder. Anorectal involvement might typically cause fecal incontinence and rarely rectal prolapse. Here we report three female patients, who were admitted with a mean history of 10 years suffering from SSc. All patients presented with the initial symptom of anal incontinence, in all cases this was associated with rectal intussusception or rectal prolapse. The three women faced prolapse recurrence, independent of the initial procedure. After surgical removal of the prolapse, the incontinence remained. In SSc rectal prolapse syndrome might occur at an earlier age, and a primary prolapse of the ventral aspect of the rectal wall seems to be typical for this disease. If patients with prior diagnosis of SSc appear with third degree of fecal incontinence, it is suspected to be associated with rectal prolapse. The prolapse recurrence rate after surgery in SSc patients is high.

    Systemic sclerosis (SSc) is an immune-mediated connective tissue disease of which the aetiology is still unclear. Previous genetic studies including candidate-gene studies and genomewide association studies have identified a number of genetic variations that confer risk to SSc. However, these variants, such as single nucleotide polymorphisms, cannot completely explain the SSc susceptibility and the diversity in the clinical symptoms of SSc patients. The contribution of epigenetic mechanisms as a link between genetics and environmental triggers represents promising field in understanding the pathogenesis of SSc. The aim of this review was to present the current knowledge on epigenetic mechanisms and highlight novel directions in diagnostic and therapeutical approaches. © 2017 The Foundation for the Scandinavian Journal of Immunology.

    2006-01-01

    Full Text Available Background. Successful treatment of severe spasticity represents an imperative of symptomatic therapy of multiple sclerosis (MS due to a significant improvement of physical, psychic and social rehabilitation of MS patients, as well as a longterm cost savings for the additional treatments of conditions arising from uncontrolled severe spasticity. Continuous intrathecal administration of baclofen (ITB, using a subcutaneously implanted programmable infusion pump, is a minimally invasive, reversible method for the treatment of severe diffuse spasticity of the spinal origin. Case report. The first two cases in our country, treated by ITB due to severe spasticity caused by MS, were reported. Despite the local complications of surgical wound healing above the implanted components of the ITB-system in one patient, the optimal reduction of spasticity the with complete elimination of spastic pain was obtained in both patients. Conclusion. Our initial experiences confirmed ITB as a safe and effective therapeutical option for the treatment of intractable spasticity in patients with MS. Major prerequisites for this were adequate patient selection and good control of the basic disease. The use of the minimal invasive implantation technique and the experience in choosing of the adequate ITB-system components, could successfully prevent the occurrence of local complications related to the impaired healing of the ITB-system implantation site.

    Raynaud's phenomenon is a vasospastic disorder of the extremities that can lead, in the hands, to pain, disability, ischemic ulcers and digital chronic ischemia. Medical and surgical current treatments are not fully effective while causing side effects. Recent studies have emphasized the value of botulinum toxin type A (BTX A) in the management of primary Raynaud's phenomenon. The originality of Raynaud's syndrome secondary to systemic sclerosis is to combine both arterial vasospasm and sclerosis of the arterial wall, what is supposed to reduce BTX A effects. The purpose of this work is to evaluate BTX A efficiency in patients with Raynaud's phenomenon secondary to systemic sclerosis. We performed a prospective study for 12 months. Patients with severe Raynaud's phenomenon due to systemic sclerosis were injected with BTX A in the two hands. Evolution of ischemic ulcers, QuickDASH Score, O2 partial pressure, pain were measured before and 30 days after injection. We treated 18 patients. Thirty days after injection, we noticed a complete healing of ulcers, QuickDASH Score was improved from 39.4 to 20, as the O2 partial pressure from 16 to 42 mmHg and the pain from VNS from 6/10 to 2/10. BTX A appears to improve significantly Raynaud's phenomenon symptomatology in patients with systemic sclerosis despite the component of arterial sclerosis. Copyright © 2011 Elsevier Masson SAS.

  15. The endocannabinoid system and multiple sclerosis.

    2008-01-01

    Multiple sclerosis (MS) is a neurodegenerative disease that is characterised by repeated inflammatory/demyelinating events within the central nervous system (CNS). In addition to relapsing-remitting neurological insults, leading to loss of function, patients are often left with residual, troublesome symptoms such as spasticity and pain. These greatly diminish "quality of life" and have prompted some patients to self-medicate with and perceive benefit from cannabis. Recent advances in cannabinoid biology are beginning to support these anecdotal observations, notably the demonstration that spasticity is tonically regulated by the endogenous cannabinoid system. Recent clinical trials may indeed suggest that cannabis has some potential to relieve, pain, spasms and spasticity in MS. However, because the CB(1) cannabinoid receptor mediates both the positive and adverse effects of cannabis, therapy will invariably be associated with some unwanted, psychoactive effects. In an experimental model of MS, and in MS tissue, there are local perturbations of the endocannabinoid system in lesional areas. Stimulation of endocannabinoid activity in these areas either through increase of synthesis or inhibition of endocannabinoid degradation offers the positive therapeutic potential of the cannabinoid system whilst limiting adverse events by locally targeting the lesion. In addition, CB(1) and CB(2) cannabinoid receptor stimulation may also have anti-inflammatory and neuroprotective potential as the endocannabinoid system controls the level of neurodegeneration that occurs as a result of the inflammatory insults. Therefore cannabinoids may not only offer symptom control but may also slow the neurodegenerative disease progression that ultimately leads to the accumulation of disability.

    Systemic sclerosis is a connective tissue disease characterized by fibrosis of the skin, internal organs, and widespread vasculopathy. Raynaud's phenomenon and digital ulcers are vascular manifestations of this disease and cause significant morbidity. Current treatments are only moderately effective in reducing the severity of Raynaud's in a portion of patients and typically do not lead to substantial benefit in terms of the healing or prevention of digital ulcers. Several studies have evaluated the efficacy of targeting the vasoconstrictor endothelin-1 for the treatment of systemic sclerosis-associated vascular disease. The purpose of this paper is to summarize the published studies and case reports evaluating the efficacy of endothelin receptor antagonists in the treatment of Raynaud's phenomenon and digital ulcers associated with systemic sclerosis.

    Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis and collagen deposits. Gastrointestinal symptoms of SSc, including abdominal pain, bloating and discomfort, are common but diffuse and their pathophysiology remains obscure. To investigate the pathophysiology of abdominal pain and discomfort in individuals with SSc. A total of 15 individuals with SSc (13 women, median age 58 years), all suffering from diffuse abdominal symptoms, and 17 healthy volunteers (12 women, median age 52 years) were evaluated with the Motility Tracking System, MTS-1, measuring gastric emptying (GE) and velocity through the small intestine. SSc patients were also examined for bacterial overgrowth using the hydrogen breath test and with radiopaque markers to determine the total gastrointestinal transit time (GITT). Assessed with the MTS-1, the velocity through the proximal small intestine was significantly reduced in SSc patients (median 0.525 m/h, range 0.11-1.15) when compared to healthy subjects (median 0.91 m/h, range 0.51-1.74) (p = 0.02). Prolonged GE was found in 4 SSc patients (27%) but in none of the healthy volunteers (p = 0.04). Only 3 SSc patients (21%) had positive breath tests for small intestinal bacterial overgrowth. GITT was >3 days in 8 patients (53%). Slow small intestinal transit was associated with a prolonged GITT (p < 0.05). Velocity through the small intestine is significantly reduced in SSc patients with diffuse abdominal symptoms.

    Systemic sclerosis (SSc) is a connective tissue disease that usually affects women, with a male:female ratio of 1:4-10. It was thought that there was a prohibitive risk of fatal complications in the pregnancies of patients with SSc. It is now known that the majority of these women undergo a normal progression of pregnancy if the right time is chosen and a close obstetric care is delivered. The obstetric risk will depend on the subtype and clinical stage of the disease, and the presence and severity of the internal organ involvement during the pregnancy. The management of these pregnancies should be provided in a specialized center, with a multidisciplinary team capable of identifying and promptly treating complications. Treatment should be limited to drugs with no teratogenic potential, except when renal crises or severe cardiovascular complications develop. Copyright © 2014 Elsevier España, S.L.U.

    A recent study identified increasing birth order to be a risk factor for the development of systemic sclerosis (SSc). This finding supports the theory that transplacental microchimerism may be a key pathological event in the initiation of SSc. We investigated the relationship between birth order and parity and the age of onset of SSc in South Australia. A retrospective analysis of patient data in the South Australian Scleroderma Register was performed. Data were obtained from a mailed questionnaire. Control data was collected prospectively using a similar questionnaire. The relationship between birth order, family size or parity and risk of subsequent development of SSc was analyzed by mixed effects logistic regression analysis. Three hundred and eighty-seven index probands were identified and compared with 457 controls. Controls were well matched for gender, but not for age. No statistically significant relationship was identified between SSc and birth order, parity in females, family size, age at first pregnancy in females or gender of first child in parous females. Our data suggests that parity, age at first pregnancy and the gender of the first child are not relevant factors in our understanding of the epidemiology and pathogenesis of SSc. Birth order and family size in both genders also appears irrelevant. These results argue against microchimerism as being relevant in the pathogenesis of SSc and add further support to the theory that stochastic events may be important in the etiopathogenesis of SSc. © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

  1. Gastro-intestinal involvement in systemic sclerosis

    Full Text Available The gastrointestinal (GI tract can be involved in up to 90% of patients with systemic sclerosis (SSc and is the leading cause of morbidity and third most common cause of mortality in these patients. The GI involvement can occur in the absence of cutaneous manifestations in 10% of patients. Vasculopathy, cellular and humoral immunity, and diffuse fibrosis are the principal pathogenetic mechanisms in SSc and begin with autoantibody-mediated neuronal damage followed by muscular damage and fibrosis. This leads to progressive dysmotility of the entire GI tract from mouth to anus and is responsible for the clinical manifestations including gastroesophageal reflux disease and dysphagia due to esophageal involvement, gastroparesis, small intestinal bacterial overgrowth and chronic intestinal pseudo-obstruction, and constipation due to colonic and fecal incontinence due to anorectal involvement. The clinical features resulting from the involvement of these organs often overlap and multiple areas may be involved simultaneously. The treatment remains mostly symptomatic because effective disease-modifying therapies are lacking. These patients are at a risk of malnutrition and nutritional screening, and thus rehabilitation is very important. Refractory cases require nutritional support in the form of enteral nutrition and/or home parenteral nutrition. Future research is needed in the pathogenesis, development of biomarkers for early identification of GI involvement at the asymptomatic stage, and targeted disease-modifying therapies, which can alter/halt the disease progression.

    Full Text Available We have reviewed scientific literature about the association of systemic sclerosis (SSc and thyroid disorders. A high incidence, and prevalence, of new cases of autoimmune thyroiditis (AT and/or hypothyroidism have been shown in sclerodermic patients (overall in the female gender. An association among a Th1 immune-predominance, low vitamin D levels, and AT have been also shown in SSc patients. Cases of Graves’ disease (GD have been described in SSc patients, too, according with the higher prevalence of thyroid autoimmunity. It has been also shown a higher prevalence of papillary thyroid cancer (PTC, in association with AT, in SSc patients. However, in order to confirm results about GD and thyroid cancer, studies in larger number of patients with SSc are needed. During the follow-up of SSc patients it would be appropriate to monitor carefully their thyroid status. The abovementioned data strongly suggest a periodic thyroid function follow-up in female SSc patients [showing a borderline high (although in the normal range thyroid-stimulating hormone level, antithyroid peroxidase antibody positivity, and a small thyroid with a hypoechoic pattern], and, when necessary, appropriate treatments. In conclusion, most of the studies show an association among SSc, AT, and hypothyroidism, such as an increased prevalence of TC overall in SSc patients with AT. Only few cases of GD have been also described in SSc.

    Systemic sclerosis is a connective tissue disorder that affects multiple organs. Although the initial symptoms of the disease are vascular, skin involvement is almost universally present in patients with systemic sclerosis. The presence of Raynaud's phenomenon, progressive thickening of the skin, digital ulcers, and calcinosis all correlate proportionally with disease severity. Since no treatment is available to completely prevent the natural course of the disease, emphasis is often placed on managing symptoms and complications. In this review, the authors focus on the management of each one of the skin manifestations seen in systemic sclerosis, as the dermatologist may facilitate the early recognition and treatment of these complications.

    Although thyroidal uptake of gallium-67 has been described in several thyroid disorders, gallium-67 scanning is not commonly used in the evaluation of thyroid disease. Thyroidal gallium-67 uptake has been reported to occur frequently with subacute thyroiditis, anaplastic thyroid carcinoma, and thyroid lymphoma, and occasionally with Hashimoto's thyroiditis and follicular thyroid carcinoma. A patient is described with progressive systemic sclerosis who, while being scanned for possible active pulmonary involvement, was found incidentally to have abnormal gallium-67 uptake only in the thyroid gland. Fine needle aspiration cytology of the thyroid revealed Hashimoto's thyroiditis. Although Hashimoto's thyroiditis occurs with increased frequency in patients with progressive systemic sclerosis, thyroidal uptake of gallium-67 associated with progressive systemic sclerosis has not, to our knowledge, been previously described. Since aggressive thyroid malignancies frequently are imaged by gallium-67 scintigraphy, fine needle aspiration cytology of the thyroid often is essential in the evaluation of thyroidal gallium-67 uptake

    Abstract Peak age at onset of systemic sclerosis (SSc) is between 20 and 50 years, although SSc is also described in both young and elderly patients. We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.2 ± 6.8 years. Based on the mean ± 1 standard deviation (SD) of age at disease onset (45 ± 15 yr) of the whole series, patients were classified into 3 groups: age ≤30 years (early onset), age between 31 and 59 years (standard onset), and age ≥60 years (late onset). We compared initial and cumulative manifestations, immunologic features, and death rates. The early-onset group included 195 patients; standard-onset group, 651; and late-onset, 191 patients. The early-onset group had a higher prevalence of esophageal involvement (72% in early-onset compared with 67% in standard-onset and 56% in late-onset; p = 0.004), and myositis (11%, 7.2%, and 2.9%, respectively; p = 0.009), but a lower prevalence of centromere antibodies (33%, 46%, and 47%, respectively; p = 0.007). In contrast, late-onset SSc was characterized by a lower prevalence of digital ulcers (54%, 41%, and 34%, respectively; p < 0.001) but higher rates of heart conduction system abnormalities (9%, 13%, and 21%, respectively; p = 0.004). Pulmonary hypertension was found in 25% of elderly patients and in 12% of the youngest patients (p = 0.010). After correction for the population effects of age and sex, standardized mortality ratio was shown to be higher in younger patients. The results of the present study confirm that age at disease onset is associated with differences in clinical presentation and outcome in SSc patients. PMID:24646463

    Currently, lung impairment is the leading factor responsible for the morbidity and mortality associated with systemic sclerosis. Therefore, the recognition of the various tomography patterns becomes decisive in the clinical management of these patients. In high-resolution computed tomography studies, the most common pattern is that of nonspecific interstitial pneumonia. However, there are other forms of lung involvement that must also be recognized. The aim of this study was to review the literature on the main changes resulting from pulmonary involvement in systemic sclerosis and the corresponding radiological findings, considering the current classification of interstitial diseases. We searched the Medline (PubMed), Lilacs, and SciELO databases in order to select articles related to pulmonary changes in systemic sclerosis and published in English between 2000 and 2015. The pulmonary changes seen on computed tomography in systemic sclerosis are varied and are divided into three main categories: interstitial, alveolar, and vascular. Interstitial changes constitute the most common type of pulmonary involvement in systemic sclerosis. However, alveolar and vascular manifestations must also be recognized and considered in the presence of atypical clinical presentations and inadequate treatment responses. (author)

    Full Text Available Introduction. Gastric antral vascular ectasia (GAVE is a rare entity with unique endoscopic appearance described as “watermelon stomach.” It has been associated with systemic sclerosis but the pathophysiological changes leading to GAVE have not been explained and still remain uncertain. Methods. Databases Medline, Scopus, Embase, PubMed, and Cochrane were searched for relevant papers. The main search words were “Gastric antral vascular ectasia,” “Watermelon Stomach,” “GAVE,” “Scleroderma,” and “Systemic Sclerosis.” Fifty-four papers were considered for this review. Results. GAVE is a rare entity in the spectrum of manifestations of systemic sclerosis with unknown pathogenesis. Most patients with systemic sclerosis and GAVE present with asymptomatic anemia, iron deficiency anemia, or heavy acute gastrointestinal bleeding. Symptomatic therapy and endoscopic ablation are the first-line of treatment. Surgical approach may be recommended for patients who do not respond to medical or endoscopic therapies. Conclusion. GAVE can be properly diagnosed and treated. Early diagnosis is key in the management of GAVE because it makes symptomatic therapies and endoscopic approaches feasible. A high index of suspicion is critical. Future studies and a critical review of the current findings about GAVE are needed to understand the role of this condition in systemic sclerosis.

    Full Text Available Marina D Kraaij, Jacob M van LaarMusculoskeletal Research Group, Institute of Cellular Medicine, School of Clinical Medical Sciences, Newcastle University, Newcastle upon Tyne NE2 4HH, United KingdomAbstract: Systemic sclerosis (SSc is a connective disease characterized by features of autoimmunity, vasculopathy, inflammation, and fibrosis. The disease typically starts with Raynaud’s phenomenon, followed by skin thickening in the extremities due to inflammation and fibrosis. Fibrosis results from excessive collagen production by fibroblasts, which constitutes the final common pathway of complex cellular interactions including B cells. Several studies have indicated that B cells may play a role in SSc. Lesional skin infiltrates from SSc patients consist of a variety of cells, including eosinophils, neutrophils, lymphocytes, plasma cells, and macrophages. Autoantibodies of several specificities are present in the serum of SSc patients of which antitopoisomerase 1 is the most common, and evidence has been gathered for a potential pathogenic role of some autoantibodies, eg, anti-PDGF antibodies. The blood of SSc patients contains an increased proportion of naïve B cells but a decreased proportion of memory B cells. Furthermore, serum levels of interleukin-6, an important pro-inflammatory cytokine, have been shown to correlate with skin fibrosis. Animal models of SSc have provided more in-depth information on the role of B lymphocytes, eg, through disruption of B cell function. In this review we will discuss the evidence that B cells are involved in the pathogenesis of SSc.Keywords: B lymphocyte, systemic sclerosis, fibrosis

    Systemic sclerosis (SSc) is a chronic multisystem autoimmune disease which involves the gastrointestinal tract in about 90% of cases. It may contribute to nutritional deterioration. To assess whether the application of a nutritional support protocol to these patients could improve their nutritional status and quality of life. Single center prospective study, performed on an outpatient basis, in a county hospital. The Malnutrition Universal Screening Tool (MUST) was used to screen risk for malnutrition. Health questionnaire SF-36 and the Hospital Anxiety and Depression Scale were used to assess quality of life and psychopathology respectively. Weight, height, energy and protein requirements, macronutrient intake and nutritional biochemical parameters were evaluated. Nutritional intervention was performed in patients at risk for malnutrition. Of the 72 patients, 12.5% were at risk for malnutrition. Iron deficiency anemia (18.35%) and vitamin D deficiency (54%) were the most frequently observed nutritional deficits. The questionnaires on psychopathology and quality of life showed a high prevalence of anxiety and depression, and lower level poor quality of life in the physical and mental component. No significant improvements were observed in the weight, food intake, nutritional biochemical parameters, psychopathology and quality of life follow-up. Dietary intervention was able to maintain body weight and food intake. Iron deficiency anemia and vitamin D deficiency improved with iron and vitamine D supplements. No deterioration was observed in psychological assessment or quality of life. Studies with larger numbers of patients are needed to assess the efficacy of this intervention.

    Purpose: To evaluate high-resolution CT (HRCT) parameters of inflammation and fibrosis in systemic sclerosis (SSc), for correlation with lung function, skin scores and exercise tolerance. Material and Methods: : 45 SSc patients (40 women, 48.5±13.4 years), underwent thoracic HRCT, lung function assessment, and modified Rodnan skin scores. Exercise tolerance was also graded. HRCT were scored for extent of 4 HRCT patterns of interstitial lung disease (ILD): ground glass opacification (GGO), reticular, mixed and honeycomb pattern in each lobe. Total HRCT score, inflammation index (GGO and mixed score) and fibrosis index (reticular and honeycomb scores) were correlated with lung function and clinical parameters. Results: ILD was present in 39/45 (86.7%) patients. Abnormal (<80% predicted) forced vital capacity (FVC), total lung capacity (TLC) and carbon monoxide diffusion factor (DLco) were detected in 30%, 22% and 46% of patients. Total HRCT score correlated with FVC (r=0.43, p=0.008), FEV1 (forced expiratory volume) (r=-0.37, p=0.03), TLC (r=-0.47, p=0.003), and DLCO (r=-0.43, p=0.008); inflammatory index with DLCO (r=-0.43, p=0.008) and exercise tolerance (r=-0.39, p < 0.05); and fibrosis index with FVC (r=-0.31, p=0.05) and TLC (r=-0.38, p=0.02). Higher total HRCT score, and inflammation and fibrosis indices were found in patients with abnormal lung function. Conclusion: Qualitative HRCT is able to evaluate inflammation and fibrosis, showing important relationships with diffusion capacity and lung volume, respectively

    Abstract Although the presence of antineutrophil cytoplasmic antibodies (ANCA) has been reported in patients with systemic sclerosis (SSc), the association of SSc and systemic vasculitis has rarely been described. We obtained information on cases of systemic vasculitis associated with SSc in France from the French Vasculitis Study Group and all members of the French Research Group on Systemic Sclerosis. We identified 12 patients with systemic vasculitis associated with SSc: 9 with ANCA-associated systemic vasculitis (AASV) and 3 with mixed cryoglobulinemia vasculitis (MCV). In all AASV patients, SSc was of the limited type. The main complication of SSc was pulmonary fibrosis. Only 2 patients underwent a D-penicillamine regimen before the occurrence of AASV. The characteristics of AASV were microscopic polyangiitis (n = 7) and renal limited vasculitis (n = 2). Anti-myeloperoxidase antibodies were found in 8 of the 9 patients. The Five Factor Score was above 1 in 3 of the 9 patients. Of the 3 patients with MCV, Sjögren syndrome was confirmed in 2. We compared our findings with the results of a literature review (42 previously reported cases of AASV with SSc). Although rare, vasculitis is a complication of SSc. AASV is the most frequent type, and its diagnosis can be challenging when the kidney is injured. Better awareness of this rare association could facilitate earlier diagnosis and appropriate management to reduce damage. PMID:23263715

  17. L-selectin and skin damage in systemic sclerosis.

    Directory of Open Access Journals (Sweden)

    James V Dunne

    Full Text Available L-selectin ligands are induced on the endothelium of inflammatory sites. L-selectin expression on neutrophils and monocytes may mediate the primary adhesion of these cells at sites of inflammation by mediating the leukocyte-leukocyte interactions that facilitate their recruitment. L-selectin retains functional activity in its soluble form. Levels of soluble L-selectin have been reported as both elevated and lowered in patients with systemic sclerosis (SSc. This preliminary study seeks to discern amongst these disparate results and to discover whether there is an association between L-selectin concentrations in plasma and skin damage in SSc patients.Nineteen cases with limited systemic sclerosis (lSSc and 11 cases with diffuse systemic sclerosis (dSSc were compared on a pairwise basis to age- and sex-matched controls. Criteria of the American College of Rheumatology were used to diagnose SSc. Skin involvement was assessed using the modified Rodnan skin score (mRSS. We find no association between mRSS and plasma L-selectin concentration in lSSc cases (p = 0.9944 but a statistically significant negative correlation in dSSc cases (R(2 = 73.11 per cent, p = 0.0008. The interpretation of the slope for dSSc cases is that for each increase of 100 ng/ml in soluble L-selectin concentration, the mRSS drops 4.22 (95 per cent CI: 2.29, 6.16. There was also a highly statistically significant negative correlation between sL-selectin and disease activity (p = 0.0007 and severity (p = 0.0007 in dSSc cases but not in lSSc cases (p = 0.2596, p = 0.7575, respectively.No effective treatments exist for skin damage in SSc patients. Nor is there a laboratory alternative to the modified Rodnan skin score as is the case for other organs within the body. Modulation of circulating L-selectin is a promising target for reducing skin damage in dSSc patients. Plasma levels of soluble L-selectin could serve as an outcome measure for dSSc patients in

    Full Text Available Background: Systemic sclerosis is a generalized disorder of connective tissue affecting skin and internal organs. Lung involvement accounts for significant morbidity and is a leading cause of mortality in patients. Objectives: This study intends to study the frequency of occurrence of pulmonary involvement in progressive systemic sclerosis (PSS and to describe the clinical and radiological picture of pulmonary involvement in PSS. Materials and Methods: This was a descriptive cross-sectional study. A detailed history, modified Rodnan score, clinical examination, routine investigation, antinuclear antibody, immuno biot, chest X-ray (CXR, pulmonary function test (PFT, and 6 min walk test (6MWT were performed on all patients. High resolution computed tomography was done on those who consented. Results: Hundred subjects with PSS were included in the study; 90 were females and 10 were males. Common presenting complaints were skin thickening in 98% and Raynaud's phenomenon in 98%. Skin thickening of digits beyond metacarpo phalangeal was seen in 98%, face and neck in 92%, and hands in 92%. Chest wall thickening was seen in 40 subjects (40%. 90 (90% of the studied subjects had pulmonary involvement, longer duration of disease was significantly associated with pulmonary involvement (P < 0.05. Dyspnea, cough, bilateral crepitations, CXR, Borg score, and Rodnan score was found to be significantly associated with severe pulmonary involvement (P < 0.05. Conclusion: The prevalence of pulmonary involvement in this cohort study was 90%. Almost 1/3rd of patients, that is 29 (29% were detected to have pulmonary involvement despite being asymptomatic for respiratory complaints, hence early screening and evaluation is recommended. PFT and 6MWT are noninvasive, cost-effective, and easily available screening tests which can be used in resource-limited settings.

    To examine the presence of depressive symptoms in patients with multiple sclerosis relapse and its relation to disability and relapse severity. This study included 120 patients who were assessed during the acute relapse of multiple sclerosis according to Mc Donald criteria. Depression was assessed using Beck Depression Inventory II (BDI-II) calculating both affective and somatic symptom scores. The Expanded Disability Status Scale (EDSS) measured disability. Relapse severity was graded according to the difference between the EDSS score during relapse and EDSS score before the onset of the attack as mild, moderate or severe. There was statistically significant difference between patients with different level of depression considering age (p<0.001), disability (p<0.001), relapse severity (p=0.005) and disease duration (p=0.032). Significant moderate positive correlation of depression with age (rho=0.43) and disability (rho=0.46) was confirmed. There was moderate correlation between disability and somatic symptoms of depression (rho=0.54, p<0.001) with only weak correlation between disability and affective symptoms of depression (rho=0.31, p<0.01). Multiple regression analysis showed that patient's age and relapse severity (p<0.05) were independently related to depression in these patients while disability did not. Correlation between disability and depression was mostly due to somatic symptoms of depression. Although highly correlated, depression during multiple sclerosis relapse was not independently predicted by disability. Depression should be recognized and treated independently from disability treatment, especially in the group of older patients with more severe relapse.

    We report a 29-month-old girl with osteopathia striata with cranial sclerosis (OS-CS), who showed several unusual manifestations, including short stature, muscular hypotonia, short lingual frenulum, an accessory ear and a granuloma at the oral edge. The most unusual distressing finding was severe cervical kyphosis with a dysplastic cervical spine. MRI revealed impingement of the upper spinal cord. To clarify the mode of inheritance of this disease in this patient, we performed a methylation-specific PCR analysis. It eventually showed random inactivation of X-chromosomes, suggesting an autosomal dominant trait. (orig.)

    To assess the importance of the Pelli-Robson contrast sensitivity test in multiple sclerosis patients according to the Expanded Disability Status Scale (EDSS). A total of 62 patients with multiple sclerosis were included in a retrospective study. Patients were enrolled from the Neurology Department to Neuroophthalmology at Virgen de la Victoria Hospital. Patients were classified into 3 groups according to EDSS: group A) lower than 1.5, group B) between 1.5 and 3.5 and group C) greater than 3.5. Visual acuity and monocular and binocular contrast sensitivity were performed with Snellen and Pelli-Robson tests respectively. Twelve disease-free control participants were also recruited. Correlations between parameter changes were analyzed. The mean duration of the disease was 81.54±35.32 months. Monocular and binocular Pelli-Robson mean values in the control group were 1.82±0.10 and 1.93±0.43 respectively, and 1.61±0.29 and 1.83±0.19 in multiple sclerosis patients. There were statistically significant differences in the monocular analysis for a level of significance P<.05. Mean monocular and binocular Pelli-Robson values in relation to gravity level were, in group A: 1.66±0.24 and 1.90±0.98, group B: 1.64±0.21 and 1.82±0.16, and group C: 1.47±0.45 and 1.73±0.32 respectively. Group differences were statistically significant in both tests: P=.05 and P=.027. Monocular and binocular contrast discrimination analyzed using the Pelli-Robson test was found to be significantly lower when the severity level, according EDSS, increases in multiple sclerosis patients.

    Homocysteine is a sulfhydryl-containing amino acid that is derived from dietary methionine, and there has been increasing evidence that elevated plasma homocysteine levels are associated with increased risk of cardiovascular diseases, including carotid, coronary and peripheral arterial disease (PAD). The association of plasma homocysteine levels with peripheral vascular involvements, such as Raynaud phenomenon (RP), digital ulcers (DU) in systemic sclerosis (SSc) patients has not been well studied. The objective of this study was to examine plasma homocysteine levels and their clinical associations in patients with SSc. Plasma homocysteine levels in 151 Japanese patients with SSc and 20 healthy controls were examined. No significant differences were observed in plasma homocysteine levels between SSc patients and healthy individuals. Demographic and clinical features of the SSc patients revealed that severe skin sclerosis, anti-topoisomerase I antibody positivity, complications of DU, acro-osteolysis (AO) and interstitial lung disease (ILD) were significantly more prevalent among the patients with elevated plasma homocysteine levels. The plasma homocysteine levels were positively correlated with modified Rodnan total skin score. The plasma homocysteine levels in the SSc patients with DU, AO and ILD were significantly higher than those in the SSc without DU, AO and ILD, respectively. Plasma homocysteine levels did not correlate with either the mean or max intima-media thickness (IMT) or plaque score, suggesting that plasma homocysteine levels might not be associated with carotid artery atherosclerosis in SSc patients. The measurement of plasma homocysteine levels in SSc patients might be useful for the risk stratifications of severe skin sclerosis, DU and AO. © 2014 Japanese Dermatological Association.

    Technologies like electronic health records or telemedicine devices support the rapid mediation of health information and clinical data independent of time and location between patients and their physicians as well as among health care professionals. Today, every part of the treatment process from diagnosis, treatment selection, and application to patient education and long-term care may be enhanced by a quality-assured implementation of health information technology (HIT) that also takes data security standards and concerns into account. In order to increase the level of effectively realized benefits of eHealth services, a user-driven needs assessment should ensure the inclusion of health care professional perspectives into the process of technology development as we did in the development process of the Multiple Sclerosis Documentation System 3D. After analyzing the use of information technology by patients suffering from multiple sclerosis, we focused on the needs of neurological health care professionals and their handling of health information technology. Therefore, we researched the status quo of eHealth adoption in neurological practices and clinics as well as health care professional opinions about potential benefits and requirements of eHealth services in the field of multiple sclerosis. We conducted a paper-and-pencil-based mail survey in 2013 by sending our questionnaire to 600 randomly chosen neurological practices in Germany. The questionnaire consisted of 24 items covering characteristics of participating neurological practices (4 items), the current use of network technology and the Internet in such neurological practices (5 items), physicians' attitudes toward the general and MS-related usefulness of eHealth systems (8 items) and toward the clinical documentation via electronic health records (4 items), and physicians' knowledge about the Multiple Sclerosis Documentation System (3 items). From 600 mailed surveys, 74 completed surveys were returned

    Full Text Available INTRODUCTION: Systemic sclerosis is a relatively rare connective tissue disorder characterized by severe and progressive fibrosis of the skin. Due to the current lack of available information on this subject, the aim of the present study was to assess light touch sensations in the hands of patients with systemic sclerosis. METHODS: We completed a cross-sectional comparative study. Light touch sensations were evaluated in 30 individuals, including 15 patients with systemic sclerosis who exhibited changes in the dermis of their hands without loss of the distal phalanx and 15 subjects who did not exhibit changes in the upper limbs (control group. The groups were age- and sex-matched. Tactile sensory evaluations were performed using the Semmes-Weinstein monofilament test and the two-point discrimination test. RESULTS: Statistically significant differences were found between groups in the monofilament test. The study group had lower scores across all points of the hand when compared with the control group. Differences were also found when dominant and non-dominant hands were compared (p<0.05. Statistically significant differences were found between groups for a subset of the assessed points in the two-point discrimination test. CONCLUSIONS: The results of a monofilament test showed that tactile sensation, specifically light touch and deep pressure sensations, is altered in the hands of systemic sclerosis patients.

    Full Text Available Unique experience of high-dose chemotherapy with consequent autologous hematopoietic stem cell transplantation in children with severe resistant multiple sclerosis (n=7 is shown in this article. At present time there is enough data on chemotherapy with consequent hematopoietic stem cell transplantation in children with severe resistant multiple sclerosis. This method was proved to be efficient and safe with immunoablative conditioning chemotherapy regimen. In patients included in this study the mean rate according to the Expanded Disability Status Scale was 5,94±0,2 (from 3 to 9 points. All the patients had disseminated demyelination loci, accumulating the contrast substance, in the brain and the spinal cord. After cyclophosphamide treatment in combination with anti-monocytes globulin the fast stabilization of the condition and prolonged (the observation period was 3-36 moths clinical and radiologic as well as immunophenotypic remission with marked positive dynamics according to the Expanded Disability Status Scale were noted. No pronounced side-effects and infectious complications were mentioned. The maximal improvement according to the Expanded Disability Status Scale (EDSS was 5,5 points, the mean — 2,7±0,1 (from 2 to 5,5 points accompanied with positive dynamics on the magneto-resonance imaging.  The efficacy of the treatment was also proved by the positive changes in the lymphocytes subpopulation status in peripheral blood. The timely performed high-dose chemotherapy with consequent hematopoietic stem cell transplantation is an effective and safe method to slowdown the autoimmune inflammatory process. This method can be recommended to use in treatment of children with severe resistant multiple sclerosis

    2014-06-01

    The purpose of this review is to familiarize the reader with the landscape of current neuro-ophthalmology research in the field of multiple sclerosis and to highlight important findings, directions of future research and advances in the clinical management of visual and ocular motor manifestations of multiple sclerosis. Research pertaining to the visual system in multiple sclerosis has identified new biomarkers of disease and is contributing to a better understanding of disease mechanisms. Progress has been made in the symptomatic management of visual manifestations of multiple sclerosis and visual outcome measures are now being included in clinical trials, with important quality of life ramifications. Perhaps the most prominent contribution from neuro-ophthalmology research in multiple sclerosis has been the establishment of the visual system as a model to study disease pathogenesis, and for the systematic, objective, and longitudinal detection and monitoring of protective and restorative neurotherapeutic strategies. The emergence of these sophisticated capabilities has been in large part due to the application of high speed, high definition, and objective methods for the elucidation of both the structure and function of visual system networks. Advances in neuro-ophthalmology research in multiple sclerosis have led to the establishment of the visual system as a model to objectively study disease pathogenesis, and for the identification of novel neurotherapeutic capabilities. With the prospects of myelin repair and neuroprotective agents increasingly becoming recognized as achievable goals, the validation and utility of new visual outcome measures quantifying changes in axonal integrity, myelin protection, and repair will likely prove invaluable.

  14. The role of platelets in the pathogenesis of systemic sclerosis

    Giuseppe A. eRamirez

    2012-06-01

    Full Text Available Systemic sclerosis (SSc is an inflammatory disease of unknown etiology characterized by widespread organ dysfunction due to fibrosis and ischemia. Its nebulous pathogenic background and the consequent absence of an etiological therapy prevent the adoption of satisfying treatment strategies, able to improve patients' quality of life and survival and stimulate researchers to identify a unifying pathogenic target. Platelets show a unique biological behavior, lying at the crossroads between vascular function, innate and adaptive immunity and regulation of cell proliferation. Consequently they are also emerging players in the pathogenesis of many inflammatory diseases, including systemic sclerosis. In the setting of SSc platelets are detectable in a persistent activated state, which is intimately linked to the concomitant presence of an injured endothelium and to the widespread activation of the innate and adaptive immune system. As a consistent circulating source of bioactive compounds platelets contribute to the development of many characteristic phenomena of SSc, such as fibrosis and impaired vascular tone.

    Full Text Available Background: Systemic sclerosis is a multisystemic autoimmune disorder. Intravenous dexamethasone pulse therapy has been used since 1998. Aim: The aim was to report the beneficial effects of dexamethasone pulse in patients of systemic sclerosis vis-á-vis the side effects. Materials and Methods: Forty-seven patients of systemic sclerosis were included. After looking at the history and physical examination, the patients were submitted to various relevant investigations. Clinical scoring of the patient was done at baseline and 6-month interval according to Furst′s organ indices score. Results: A total of 47 patients of systemic sclerosis were included (45 females, 2 males. In majority, acrosclerosis was seen. Severe sclerosis and contractures were seen in two patients. Moderate proteinuria, restrictive lung disease, dysphagia, and valvular heart involvement were seen. A total of 13 patients on dexamethasone pulse therapy developed tuberculosis. Improvement in skin scoring and decreased severity of Raynaud′s phenomenon was seen. No improvement in dysphagia, severe vascular symptoms, or restrictive lung disease was seen. Conclusion: Thus, beneficial effects of dexamethasone pulse therapy seem to be merely cosmetic.

  16. Penile involvement in Systemic Sclerosis: New Diagnostic and Therapeutic Aspects

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Systemic Sclerosis (SSc is a connective tissue disorder featuring vascular alterations and an immunological activation leading to a progressive and widespread fibrosis of several organs such as the skin, lung, gastrointestinal tract, heart, and kidney. Men with SSc are at increased risk of developing erectile dysfunction (ED because of the evolution of early microvascular tissutal damage into corporeal fibrosis. The entity of penile vascular damage in SSc patients has been demonstrated by using Duplex ultrasonography and functional infra-red imaging and it is now clear that this is a true clinical entity invariably occurring irrespective of age and disease duration and constituting the ‘‘sclerodermic penis’’. Once-daily phosphodiesterase type-5 (PDE5 inhibitors improve both sexual function and vascular measures of cavernous arteries by improving surrogate markers of endothelial dysfunction, that is, plasma endothelin-1 and adrenomedullin levels, which may play a potential role in preventing progression of penile fibrosis and ED. Also, the beneficial effect of long-term PDE5i add-on therapy to SSc therapy in the treatment of Raynaud's phenomenon is described.

    To date, there are no large studies on videocapsule endoscopy in systemic sclerosis (SSc). Consequently, the prevalence and features of gastrointestinal mucosal abnormalities in SSc have not been determined. To determine both prevalence and characteristics of gastrointestinal mucosal abnormalities in unselected patients with SSc, using videocapsule endoscopy. To predict which SSc patients are at risk of developing potentially bleeding gastrointestinal vascular mucosal abnormalities. Videocapsule endoscopy was performed on 50 patients with SSc. Prevalence of gastrointestinal mucosal abnormalities was 52%. Potentially bleeding vascular mucosal lesions were predominant, including: watermelon stomach (34.6%), gastric and/or small intestinal telangiectasia (26.9%) and gastric and/or small intestinal angiodysplasia (38.5%). SSc patients with gastrointestinal vascular mucosal lesions more often exhibited: limited cutaneous SSc (P = 0.06), digital ulcers (P = 0.05), higher score of nailfold videocapillaroscopy (P = 0.0009), anaemia (P = 0.02), lower levels of ferritin (P correlation between gastrointestinal vascular mucosal lesions and presence of severe extra-digestive vasculopathy (digital ulcers and higher nailfold videocapillaroscopy scores). This latter supports the theory that SSc-related diffuse vasculopathy is responsible for both cutaneous and digestive vascular lesions. Therefore, we suggest that nailfold videocapillaroscopy may be a helpful test for managing SSc patients. In fact, nailfold videocapillaroscopy score should be calculated routinely, as it may result in identification of SSc patients at higher risk of developing potentially bleeding gastrointestinal vascular mucosal lesions. © 2014 John Wiley & Sons Ltd.

    The MSDS (multiple sclerosis documentation system) has been developed at the Department of Neurology, Technical University of Dresden, Germany, during the last 4 years. The first version of this database application has been in use since October 2000. The MSDS manages information on MS patients, their treating physicians, patient history (symptoms, other diseases, biographical history, family history, habits, medication), clinical signs, results of laboratory examinations (blood chemistry, autoantibodies, borrelia serology, evoked potentials, cranial and spinal cord magnetic resonance imaging), clinical scores relevant for MS, and biosamples. In principle, MSDS allows online data input and semiautomatically generates reports to all general practitioners and neurologists treating the respective patient. Patient information sheets and internal treatment guidelines are part of the system. During a 3-month evaluation, the first version of MSDS was tested at eight university multiple sclerosis ambulatory care units and one general neurology hospital. The overall judgement was favorable. Suggestions for changes and improvements, as well as practical experiences, were considered when developing MSDS 2.0, which will be available by the end of 2001.

  19. The Role of PPAR Gamma in Systemic Sclerosis

    Directory of Open Access Journals (Sweden)

    Andréa Tavares Dantas

    2015-01-01

    Full Text Available Fibrosis is recognized as an important feature of many chronic diseases, such as systemic sclerosis (SSc, an autoimmune disease of unknown etiology, characterized by immune dysregulation and vascular injury, followed by progressive fibrosis affecting the skin and multiple internal organs. SSc has a poor prognosis because no therapy has been shown to reverse or arrest the progression of fibrosis, representing a major unmet medical need. Recently, antifibrotic effects of PPARγ ligands have been studied in vitro and in vivo and some theories have emerged leading to new insights. Aberrant PPARγ function seems to be implicated in pathological fibrosis in the skin and lungs. This antifibrotic effect is mainly related to the inhibition of TGF-β/Smad signal transduction but other pathways can be involved. This review focused on recent studies that identified PPARγ as an important novel pathway with critical roles in regulating connective tissue homeostasis, with emphasis on skin and lung fibrosis and its role on systemic sclerosis.

    2013-01-01

    To review and assess the role of vitamin D in the onset, progression, and relapse of multiple sclerosis (MS), based on evidence acquired from the analysis of preclinical, observational, and interventional studies. All English language literature in MEDLINE (January 1969 through April 2012) was searched for observational and interventional studies on the dosage effect of vitamin D on the onset, progression, and relapse rate of MS. The medical subject heading (MeSH) terms used in the search included Vitamin D and Multiple Sclerosis. Additional publications and abstracts were identified from review articles and from the references cited in the previously found articles. In addition to the experimental studies, only those human studies that specified the population size, doses of vitamin D used, and the resulting effect on MS were considered. Vitamin D deficiency is very common among MS patients. Multiple preclinical studies have shown that vitamin D is a potent regulator of inflammation in MS. Most observational studies support an association between high vitamin D levels and a reduced risk of developing MS. However, conflicting results have been reported by observational studies on the correlation between vitamin D and MS severity and by interventional studies using vitamin D as a therapeutic agent for MS. Vitamin D deficiency in MS patients should be avoided. In addition, the risk of developing MS might be reduced by maintaining optimal vitamin D levels in the healthy population. Larger randomized interventional trials are needed to clarify the therapeutic effect of vitamin D in MS.

    The utility of perfusion-weighted imaging in multiple sclerosis (MS) is not well investigated. The purpose of this study was to compare baseline normalized perfusion measures in subgroups of newly diagnosed MS patients. We wanted to test the hypothesis that this method can differentiate between groups defined according to disease severity and disease activity at 1 year follow-up. Baseline magnetic resonance imaging (MRI) including a dynamic susceptibility contrast perfusion sequence was performed on a 1.5-T scanner in 66 patients newly diagnosed with relapsing-remitting MS. From the baseline MRI, cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) maps were generated. Normalized (n) perfusion values were calculated by dividing each perfusion parameter obtained in white matter lesions by the same parameter obtained in normal-appearing white matter. Neurological examination was performed at baseline and at follow-up approximately 1 year later to establish the multiple sclerosis severity score (MSSS) and evidence of disease activity (EDA). Baseline normalized mean transit time (nMTT) was lower in patients with MSSS >3.79 (p = 0.016), in patients with EDA (p = 0.041), and in patients with both MSSS >3.79 and EDA (p = 0.032) at 1-year follow-up. Baseline normalized cerebral blood flow and normalized cerebral blood volume did not differ between these groups. Lower baseline nMTT was associated with higher disease severity and with presence of disease activity 1 year later in newly diagnosed MS patients. Further longitudinal studies are needed to confirm whether baseline-normalized perfusion measures can differentiate between disease severity and disease activity subgroups over time. (orig.)

    Recurrent gastrointestinal haemorrhage is an uncommon manifestation of systemic sclerosis. We report a case of gastrointestinal bleeding due to gastric antral vascular ectasia (GAVE) in a patient with systemic sclerosis. Failure to recognise the condition as a cause of gastrointestinal bleeding may delay the instigation of appropriate treatment. GAVE should be considered in the differential diagnosis of anaemia in patients with autoimmune conditions such as systemic sclerosis and primary biliary cirrhosis.

    Systemic sclerosis (SSc; scleroderma) is associated with decreased saliva production and interincisal distance, more missing teeth, and periodontal disease. We undertook this study to determine the clinical correlates of SSc with these oral abnormalities. Subjects were recruited from the Canadian Scleroderma Research Group cohort. Detailed dental and clinical examinations were performed according to standardized protocols. Associations between dental abnormalities and selected clinical and serologic manifestations of SSc were examined. One hundred sixty-three SSc subjects were included: 90% women, mean ± SD age 56 ± 11 years, mean ± SD disease duration 14 ± 8 years, 72% with limited cutaneous disease, and 28% with diffuse cutaneous disease. Decreased saliva production was associated with Sjögren's syndrome-related autoantibodies (β = -43.32; 95% confidence interval [95% CI] -80.89, -5.75), but not with disease severity (β = -2.51; 95% CI -8.75, 3.73). Decreased interincisal distance was related to disease severity (β = -1.02; 95% CI -1.63, -0.42) and the modified Rodnan skin thickness score (β = -0.38; 95% CI -0.53, -0.23). The number of missing teeth was associated with decreased saliva production (relative risk [RR] 0.97; 95% CI 0.94, 0.99), worse hand function (RR 1.52; 95% CI 1.13, 2.02), and the presence of gastroesophageal reflux disease (GERD; RR 1.68 [95% CI 1.14, 2.46]). No clinical or serologic variables were correlated with periodontal disease. In SSc, diminished interincisal distance is related to overall disease severity. Decreased saliva production is related to concomitant Sjögren's syndrome antibodies. Tooth loss is associated with poor upper extremity function, GERD, and decreased saliva. The etiology of excess periodontal disease is likely multifactorial and remains unclear. © 2015, American College of Rheumatology.

    Autoimmune thyroid disorders (AITD) are characterized by the impairment of the thyroid gland as a result of systemic or organ-specific autoimmune disorders, and the presence of antithyroid autoantibodies, such as antithyroglobulin antibody (AbTg) and antithyroid peroxidase antibody (AbTPO). Several studies have reported the association of AITD with systemic sclerosis (SSc). However, none of those studies analyzed the association between AITD and skin sclerosis in SSc patients. The aim of this study was to examine the demographic and clinical features of SSc patients with AITD treated in our department. Of a total of 210 SSc patients, we identified 30 with AITD (14.3%), including 29 with Hashimoto's disease (13.8%) and one patient with Graves' disease (0.5%), indicating that hypothyroidism was more common among SSc patients with AITD. All patients with AITD were female, and anticentromere antibody positivity, the complication of Sjögren's syndrome, severe facial skin sclerosis and atrophy of the thyroid gland were significantly prevalent in SSc patients with AITD. SSc patients with such clinical features may be at high risk of AITD and require regular follow up of thyroid function including ultrasonography and the examination of serum hormone levels to start an early treatment. © 2014 Japanese Dermatological Association.

    Systemic sclerosis is a life-threatening autoimmune disease characterized by vasculopathy, which results in myocardial involvement in an extremely high percentage of patients. Nevertheless, there have been no large-scale epidemiological studies about the risk of acute myocardial infarction in patients with systemic sclerosis. The aims of this study were to evaluate the hazard ratio (HR) and risk factors of acute myocardial infarction in patients with systemic sclerosis, as well as to compare the risks of acute myocardial infarction among systemic sclerosis patients taking different immunosuppressors. The study cohort included 1344 patients with systemic sclerosis and 13,440 (1:10) age-, sex-, and comorbidity-matched controls during the period between 1997 and 2006, from the National Health Insurance Research Database. We compared the risk of acute myocardial infarction between patients with systemic sclerosis and controls and calculated the adjusted HRs for acute myocardial infarction in systemic sclerosis patients taking immunosuppressors and not taking immunosuppressors. The incidence rates of acute myocardial infarction were 535 and 313 cases per 100,000 person-years for systemic sclerosis cohort and reference cohort, respectively (P systemic sclerosis was found to be an independent risk factor for acute myocardial infarction (HR 2.45). Other risk factors included hypertension (HR 2.08) and diabetes (HR 2.14). The multivariate adjusted HR for acute myocardial infarction did not decrease among the systemic sclerosis patients taking systemic steroids, penicillamine, cyclophosphamide, azathioprine, methotrexate, or cyclosporine. Systemic sclerosis is independently associated with an increased risk of acute myocardial infarction. Immunosuppressors do not lower the risk of acute myocardial infarction in our study.

    This study aims to assess the prevalence of gastric electrical activity dysfunction with cutaneous electrogastrography (EGG), disturbances of gastric emptying function using radiopaque pellets, and gastric endoscopic abnormalities in patients with systemic sclerosis (SSc). We also investigate for an association between EGG and gastric-emptying data with clinical manifestations and esophageal motor disturbances. Fasting and postprandial gastric electrical activity was studied in 22 consecutive patients with SSc (17 with and 5 without clinical gastric manifestations) and 22 age- and sex-matched healthy subjects. Gastric emptying of radiopaque pellets and gastroscopy were also performed in SSc patients. The prevalence of EGG disturbances was as high as 81.82% in SSc patients. SSc patients exhibited, compared with controls, higher median percentage of dominant frequency in bradygastria during the fasting period and lower median values for postprandial electrical power and postprandial to fasting ratio for electrical power. Gastric emptying of radiopaque pellets was delayed in 11 SSc patients, and gastroscopy demonstrated "watermelon stomach" in 3 SSc patients. No correlation was found between the severity of gastric impairment and clinical presentation, SSc duration and subsets, and esophageal manometric impairment. Our study underlines the high frequency of gastric dysfunction in SSc patients. It suggests the usefulness of EGG in SSc in noninvasively detecting disorders of gastric electrical activity at an early stage and symptomatic patients with gastroparesis (because there was a correlation between values of postprandial to fasting ratio for electrical power of watermelon stomach diagnosis should be excluded in SSc patients presenting with gastrointestinal hemorrhage or with anemia related to iron deficiency.

    Tissue injury triggers the activation and differentiation of multiple cell types to minimize damage and initiate repair processes. In systemic sclerosis, these repair processes appear to run unchecked, leading to aberrant remodeling and fibrosis of the skin and multiple internal organs, yet the fundamental pathological defect remains unknown. We describe herein a transition wherein the abundant CD34(+) dermal fibroblasts present in healthy human skin disappear in the skin of systemic sclerosis patients, and CD34(-), podoplanin(+), and CD90(+) fibroblasts appear. This transition is limited to the upper dermis in several inflammatory skin diseases, yet in systemic sclerosis, it can occur in all regions of the dermis. In vitro, primary dermal fibroblasts readily express podoplanin in response to the inflammatory stimuli tumor necrosis factor and IL-1β. Furthermore, we show that on acute skin injury in both human and murine settings, this transition occurs quickly, consistent with a response to inflammatory signaling. Transitioned fibroblasts partially resemble the cells that form the reticular networks in organized lymphoid tissues, potentially linking two areas of fibroblast research. These results allow for the visualization and quantification of a basic stage of fibroblast differentiation in inflammatory and fibrotic diseases in the skin.

    Concern about falling can have devastating physical and psychological consequences in people with multiple sclerosis (MS). However, little is known about physical and cognitive determinants for increased concern about falling inthis group. To investigate direct and indirect relationships between MS severity and concern about falling using structural equation modelling (SEM). Two hundred and ten community-dwelling people (21-73 years) with MS Disease Steps 0-5 completed several physical, cognitive and psychological assessments. Concern about falling was assessed using the Falls Efficacy Scale-International. Concern about falling was significantly associated with MS Disease Step and also balance, muscle strength, disability, previous falls, and executive functioning. SEM revealed a strong direct path between MS Disease Step and concern about falling (r = 0.31, p falling in people with MS and had an excellent goodness-of-fit. The relationship between MS severity and increased concern about falling was primarily mediated by reduced physical ability (especially if this resulted in disability and falls) and less so by executive functioning. This suggests people with MS have a realistic appraisal of their concern about falling.

    Multiple sclerosis (MS) is a chronic disease of central nervous system. The multiple sclerosis information system (MSIS), such as other information system (IS), depends on identification, collection and processing of data for producing useful information. Lack of the integrated IS for collecting standard data causes undesirable effects on exchanging, comparing, and managing. The aim of this study was to recognize the role of the IS in the MS management and determine the advantages and barriers in implementing of the MSIS. The present study was a nonsystematized review that was done in order to recognize the role of the IS in the MS management. In this study, electronic scientific resources such as scientific magazines and books and published topics at conferences were used. We used key words (IS, chronic disease management, and multiple sclerosis), their combination or their synonyms in title, key words, abstracts, and text of English articles and published reports from 1980 until 2013, and by using search engines such as Google, Google Scholar and scientific databases and electronic issues such as iPubMed, sufficiently important difference, Scopus, Medlib, and Magiran for gathering information. More than 200 articles and reports were collected and assessed and 139 of them. Findings showed that the MSIS can reduce of disease expenses through continuously collecting correct, accurate, sufficient, and timely patients and disease nature information; recoding; editing; processing; exchanging, and distributing among different health care centers. Although the MSIS has many advantages; but, we cannot ignore cultural, economic, technical, organizational, and managerial barriers. Therefore, it is necessary to do studies for preventing, reducing, and controlling them. One of the ways is to recognize the advantages of the MSIS and usage information technology in optimizing disease management. PMID:25709660

    Conclusions: In our patients, pulmonary involvement was more common than cardiac involvement. Interstitial lung disease and cardiac involvement were more commonly seen in diffuse systemic sclerosis whereas pulmonary hypertension was more frequent in limited systemic sclerosis. Hence, it is important to screen the patients for cardiopulmonary involvement for early diagnosis and treatment and a better prognostic outcome.

    A 66-year-old patient presented in our clinic with increasing painful swelling of his hands, whole body stiffness, weight loss and dyspnoea upon exercise. The physical examination revealed a marked skin sclerosis of hands, extremities and the face. Fist closure was impossible. Pulmonary CT scan showed lung fibrosis and ground glass opacities. Antinuclear antibodies and antibodies against Scl70 were positive. CRP, LDH, NT-Pro-BNP were elevated. A diffuse cutaneous systemic sclerosis with an active interstitial pneumonia and lung fibrosis was diagnosed. Three pulses of cyclophosphamide 1.4 g every three weeks were ineffective to halt the progression of skin sclerosis, joint contractures and decline of pulmonary function. Mobilisation chemotherapy was initialized and blood stem cells were harvested. Blood stem cells were reinfused after myeloablative chemotherapy with melphalan. A maintainance therapy with mycophenolic acid was initiated after recovery of hematopoiesis. Six months after blood stem cell transplantation a decrease of skin sclerosis and an increasing recovery of joint mobility and physical strength was observed. Patients with a progressive systemic sclerosis and further risk factors should be treated with high-dose chemotherapy with blood stem cell transplantation before organ function is severely compromised. In cases with contraindications against cyclophosphamide or anti-thymocyte-globulin melphalan can be discussed as an alternative. © Georg Thieme Verlag KG Stuttgart · New York.

    The purpose of this study was to compare the specific activity of proteinase A in Candida albicans (C. albicans) between multiple sclerosis (MS) patients and controls. A total of 135 and 100 C. albicans strains were isolated from superficial surfaces of MS patients and healthy controls. Analytical models (regression and neural network) were applied to predict the severity of MS considering specific enzyme activity (SEA) and other factors which affect the expanded disability status scale (EDSS). The SEA of C. albicans in MS patients (3466.95 ± 277.25 μmol min -1 mg -1 ) was significantly more than that of healthy controls (1108.98 ± 294.51 μmol min -1 mg -1 ) that was confirmed by regression model (P albicans in MS patients was significantly more than the healthy controls. The results suggest that the level of SEA of proteinase A and probably the capacity of C. albicans isolates to invade the host tissue is associated with the severity of MS. © 2016 Blackwell Verlag GmbH.

    The aim was to update the 2009 European League against Rheumatism (EULAR) recommendations for the treatment of systemic sclerosis (SSc), with attention to new therapeutic questions. Update of the previous treatment recommendations was performed according to EULAR standard operating procedures. The task force consisted of 32 SSc clinical experts from Europe and the USA, 2 patients nominated by the pan-European patient association for SSc (Federation of European Scleroderma Associations (FESCA)), a clinical epidemiologist and 2 research fellows. All centres from the EULAR Scleroderma Trials and Research group were invited to submit and select clinical questions concerning SSc treatment using a Delphi approach. Accordingly, 46 clinical questions addressing 26 different interventions were selected for systematic literature review. The new recommendations were based on the available evidence and developed in a consensus meeting with clinical experts and patients. The procedure resulted in 16 recommendations being developed (instead of 14 in 2009) that address treatment of several SSc-related organ complications: Raynaud's phenomenon (RP), digital ulcers (DUs), pulmonary arterial hypertension (PAH), skin and lung disease, scleroderma renal crisis and gastrointestinal involvement. Compared with the 2009 recommendations, the 2016 recommendations include phosphodiesterase type 5 (PDE-5) inhibitors for the treatment of SSc-related RP and DUs, riociguat, new aspects for endothelin receptor antagonists, prostacyclin analogues and PDE-5 inhibitors for SSc-related PAH. New recommendations regarding the use of fluoxetine for SSc-related RP and haematopoietic stem cell transplantation for selected patients with rapidly progressive SSc were also added. In addition, several comments regarding other treatments addressed in clinical questions and suggestions for the SSc research agenda were formulated. These updated data-derived and consensus-derived recommendations will help

  10. Novel Neuroprotective Multicomponent Therapy for Amyotrophic Lateral Sclerosis Designed by Networked Systems.

    Directory of Open Access Journals (Sweden)

    Mireia Herrando-Grabulosa

    Full Text Available Amyotrophic Lateral Sclerosis is a fatal, progressive neurodegenerative disease characterized by loss of motor neuron function for which there is no effective treatment. One of the main difficulties in developing new therapies lies on the multiple events that contribute to motor neuron death in amyotrophic lateral sclerosis. Several pathological mechanisms have been identified as underlying events of the disease process, including excitotoxicity, mitochondrial dysfunction, oxidative stress, altered axonal transport, proteasome dysfunction, synaptic deficits, glial cell contribution, and disrupted clearance of misfolded proteins. Our approach in this study was based on a holistic vision of these mechanisms and the use of computational tools to identify polypharmacology for targeting multiple etiopathogenic pathways. By using a repositioning analysis based on systems biology approach (TPMS technology, we identified and validated the neuroprotective potential of two new drug combinations: Aliretinoin and Pranlukast, and Aliretinoin and Mefloquine. In addition, we estimated their molecular mechanisms of action in silico and validated some of these results in a well-established in vitro model of amyotrophic lateral sclerosis based on cultured spinal cord slices. The results verified that Aliretinoin and Pranlukast, and Aliretinoin and Mefloquine promote neuroprotection of motor neurons and reduce microgliosis.

    Systemic sclerosis is a chronic disabling disease that is often associated with severe physical and psychological impairment. Nonetheless, health-related quality of life (HRQoL) in patients with systemic sclerosis is often left behind in clinical practice and research. One of the reasons for this lack of evaluation is the current use of tools, such as the short form-36 (SF-36) questionnaire, that are complete but complicated to use in everyday routine. Other self-reported outcome measures such as the health assessment questionnaire (HAQ) are simple, but specifically designed for physical disability. Our aim was to evaluate the feasibility, acceptability and construct validity of EQ-5D, a simple and quick self-assessment tool, and to compare its performance with SF-36 and HAQ. We investigated 119 consecutive patients with systemic sclerosis (94% female; age: median 63 years, interquartile range 53-70 years) at three different rheumatology centres. Acceptability was evaluated from comments made by the patients and feasibility on the basis of the number of patients needing assistance or not answering questions (missing data). Construct validity was based on both convergent and divergent validity between conceptually similar and dissimilar domains, respectively, of the compared instruments. EQ-5D was well accepted by patients. The percentage of patients missing data in at least one EQ-5D domain was 2.5%. Spearman's correlation coefficients between similar dimensions of EQ-5D vs SF-36 and vs HAQ were moderate (≥0.30) to strong (≥0.50); in contrast, correlation coefficients between less comparable dimensions were weak. As expected, the EQ-5D anxiety/depression domain did not correlate with any of the HAQ domains. The EQ-5D visual analogue scale (VAS) concordance with SF-36 general health domain and HAQ total score was strong (≥0.50 for both). Median value for the EQ-5D index (interquartile range) was 0.81 (0.75-0.86). The EQ-5D index had correlation coefficients >0

    Self-injury and aggression have been reported in individuals with TSC (tuberous sclerosis complex), yet few data exist about treatment. Everolimus, an mTOR inhibitor, has been FDA-approved for subependymal giant cell astrocytomas (SEGAs) and renal angiomyolipomas in TSC. However, clinical use of everolimus with direct, real-time observations of self-injury and aggression in an individual with TSC has not been reported. During an inpatient admission to a neurobehavioral unit, real-time measurements of behaviors and seizures were recorded. An interdisciplinary team used these data to make treatment decisions and applied behavioral and pharmacological treatments, one at a time, in order to evaluate their effects. Aggression and self-injury improved with applied behavioral analysis (ABA), lithium, and asenapine. Improvements in SEGA size, facial angiofibromas, seizures, and the most stable low rates of self-injury were observed during the interval of treatment with everolimus. Mechanism-based treatments in the setting of an evidence-based behavioral and psychopharmacological intervention program may be a model with utility for characterization and treatment of individuals with severe behavior and TSC.

    Amyotrophic lateral sclerosis (ALS) is a fatal adult-onset degenerative disease characterized by the loss of upper and lower motor neurons leading to progressive muscle atrophy and paralysis. The lack of molecular markers of the progression of disease is detrimental to clinical practice and therapeutic trials. This study was designed to identify gene expression changes in skeletal muscle that could reliably define the degree of disease severity. Gene expression profiles were obtained from the deltoid muscles of ALS patients and healthy subjects. Changes in differentially expressed genes were compared to the status of deltoid muscle disability, as determined by manual muscle testing, electrophysiology and the degree of myofiber atrophy. Functionally related genes were grouped by annotation analysis, and deltoid muscle injury was predicted using binary tree classifiers. Two sets of 25 and 70 transcripts appeared differentially regulated exclusively in early and advanced states of deltoid muscle impairment, respectively. The expression of another set of 198 transcripts correlated with a composite score of muscle injury combining manual muscle testing and histological examination. From the totality of these expression changes, 155 transcripts distinguished advanced from early deltoid muscle impairment with 80% sensitivity and 100% specificity. Nine of these transcripts, known also to be regulated in ALS mouse and surgically denervated muscle, predicted the advanced disease status with 100% sensitivity and specificity. We provide robust gene expression changes that can be of practical use when monitoring ALS status and the effects of disease-modifying drugs. Copyright © 2011 S. Karger AG, Basel.

    Multiple sclerosis (MS) is a major chronic demyelinating and inflammatory disease of the central nervous system (CNS) in which oxidative stress likely plays a pathogenic role in the development of myelin and neuronal damage. Metallothioneins (MTs) are antioxidant proteins induced in the CNS...... by tissue injury, stress and some neurodegenerative diseases, which have been postulated to play a neuroprotective role. In fact, MT-I+II-deficient mice are more susceptible to developing experimental autoimmune encephalomyelitis (EAE), and treatment of Lewis rats with Zn-MT-II reduces EAE severity. We show...

    Full Text Available Evidence suggests that neurohormones such as GH and IGF-I are involved in the neuroreparative processes in multiple sclerosis (MS. GH and IGF-I blood levels in naïve MS patients with different disease courses were investigated in this study. Serum GH and IGF-I in untreated MS patients (n=64, healthy controls (HC, n=62, and patients affected by other neurological diseases (OND, n=46 were evaluated with a solid-phase-enzyme-labeled-chemiluminescent-immunometric assay. No differences were detected in GH across MS, OND, and HC (MS=0.87±1.32 ng/mL; OND=1.66±3.7; and HC=1.69±3.35; P=0.858 when considering gender, disease duration, and disease course. However, GH was lower (P=0.007 in patients with more severe disease (expanded disability scale score, EDSS≥4.0 compared with milder forms (EDSS<4. IGF-I l did not differ across the 3 groups (P=0.160, as far as concern disease course, disability, and gender were. Lower IGF-I levels were detected in subjects older than 50 years compared to younger ones for all 3 groups. Lower GH was detected in patients with more severe MS, and age was confirmed as the main factor driving IGF-I levels in all subjects. These findings, relying on the natural course of the disease, could help in shedding lights on the mechanisms involved in autoreparative failure associated with poorer prognosis in MS.

    Diabetic sclerodactyly is a frequently recognized skin finding that may occur in patients with diabetes mellitus but coexistence of diabetes and systemic sclerosis is rare. We describe a case of coexistence of type 1 diabetes mellitus and systemic sclerosis in 42-year-old man with the history of Raynaud's phenomenon, progressive diffuse hardening of the skin and sclerodactyly, slowly worsening with time. The medical history included type 1 diabetes since childhood with microvascular complications. The patient presented a typical capillaroscopic scleroderma-like pattern, antinuclear antibodies and sclerotic lesions in gastrointestinal system. Summing up, our case represents the rare coexistence of autoimmune diseases like diabetes mellitus type 1 and systemic sclerosis.

    Using computed thermography continuous temperature recordings were made before and after cold challenge of the fingers of control subjects and patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis. Basal skin temperature measurements (Tpre) were significantly lower in patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis than in the controls. Temperatures immediately after cold challenge (T0) were significantly lower in patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis than in controls. The lag phase before the start of temperature recovery (Tlag) was significantly greater in patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis than in control subjects. The maximum recovery index (R%) was significantly less in patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis than in controls. The maximum rate of change of temperature during the rapid phase of rewarming (Gmax) was significantly greater in controls than in patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis. Discriminant analysis showed that the dynamic parameters of rewarming (Tlag, Gmax, and R%) showed greater variation between the patients with primary Raynaud's phenomenon and those with Raynaud's phenomenon associated with systemic sclerosis than did Tpre or T0. This method of analysis of cold challenge will be used in studies of the effects of treatment of Raynaud's phenomenon. PMID:1466594

    Although the natural history of multiple sclerosis has been charted extensively, it is still not known whether the trajectory of disability accumulation has changed in the era of disease-modifying therapies (DMTs). The objective of this study was to examine trends in Multiple Sclerosis Severity Score (MSSS) with regard to calendar year of enrollment into the New York State MS Consortium (NYSMSC). Distributions of MSSS were calculated for each year of enrollment, from 1996 to 2007. Quantile regression was used in a multivariable analysis to model for conditional distribution of MSSS quantiles as functions of potential confounders. The cohort consisted of 6238 patients. Mean age at enrollment was 38 years (SD=10) and mean disease duration was 10.1 years (SD=7.3); 57% were on DMTs. The quantile regression model of trends in MSSS between 1996 and 2007 controlled for age, sex, ethnicity, diagnostic delay, and disease duration and demonstrated a robust trend toward lower MSSS with increasing year of enrollment. The model-predicted median MSSS at enrollment in 1996 was 5.04 (95% CI, 4.86-5.21), and in 2007 was 3.78 (95%CI, 3.36-4.20; pmigration, and recall biases.

  1. Motor Imagery as a Function of Disease Severity in Multiple Sclerosis: An fMRI Study

    Full Text Available Motor imagery (MI is defined as mental execution without any actual movement. While healthy adults usually show temporal equivalence, i.e., isochrony, between the mental simulation of an action and its actual performance, neurological disorders are associated with anisochrony. Unlike in patients with stroke and Parkinson disease, only a few studies have investigated differences of MI ability in multiple sclerosis (MS. However, the relationship among disease severity, anisochrony and brain activation patterns during MI has not been investigated yet. Here, we propose to investigate MI in MS patients using fMRI during a behavioral task executed with dominant/non-dominant hand and to evaluate whether anisochrony is associated with disease severity. Thirty-seven right-handed MS patients, 17 with clinically isolated syndrome (CIS suggestive of MS and 20 with relapsing-remitting MS (RR-MS and 20 right-handed healthy controls (HC underwent fMRI during a motor task consisting in the actual or imaged movement of squeezing a foam ball with the dominant and non-dominant hand. The same tasks were performed outside the MRI room to record the number of actual and imagined ball squeezes, and calculate an Index of performance (IP based on the ratio between actual and imagined movements. IP showed that a progressive loss of ability in simulating actions (i.e., anisochrony more pronounced for non-dominant hand, was found as function of the disease course. Moreover, anisochrony was associated with activation of occipito-parieto-frontal areas that were more extensive at the early stages of the disease, probably in order to counteract the changes due to MS. However, the neural engagement of compensatory brain areas becomes more difficult with more challenging tasks, i.e., dominant vs. non-dominant hand, with a consequent deficit in behavioral performance. These results show a strict association between MI performance and disease severity, suggesting that, at early

    Chronic impaired venous outflow from the central nervous system has recently been claimed to be associated with multiple sclerosis (MS) pathology. This resulted in the term chronic cerebrospinal venous insufficiency (CCSVI) in MS. The concept of CCSVI is based on sonography studies showing that impaired venous outflow leading to pathological reflux is almost exclusively present in MS patients but not in healthy controls. Based on these findings, a new pathophysiological concept has been introduced suggesting that chronic venous outflow obstruction and venous reflux in the CNS result in pathological iron depositions leading to inflammation and neurodegeneration. The theory of CCSVI in MS has rapidly generated tremendous interest in the media and among patients and the scientific community. In particular, the potential shift in treatment concepts possibly leading to an interventional treatment approach including balloon angioplasty and venous stent placement is currently being debated. However, results from recent studies involving several imaging modalities have raised substantial concerns regarding the CCSVI concept in MS. In this review article, we explain the concept of CCSVI in MS and discuss this hypothesis in the context of MS pathophysiology and imaging studies which have tried to reproduce or refute this theory. In addition, we draw some major conclusions focusing in particular on the crucial question as to whether interventional treatment options are expedient. In conclusion, the present conclusive data confuting the theory of CCSVI in MS should lead to reluctance with respect to the interventional treatment of possible venous anomalies in MS patients.

  3. OAS1: a multiple sclerosis susceptibility gene that influences disease severity.

    LENUS (Irish Health Repository)

    O'Brien, M

    2012-02-01

    BACKGROUND: Type 1 interferons upregulate oligoadenylate synthetase 1 (OAS1). A single nucleotide polymorphism (SNP) in exon 7 of OAS1 results in differential RNAseL enzyme activity, the A allele coding for a truncated form with low activity and the G conferring high activity. We hypothesized that OAS1 genotypes would influence both susceptibility to multiple sclerosis (MS) and disease activity with the AA genotype being overrepresented and the GG genotype underrepresented in relapsing-remitting MS (RRMS) with increased disease activity. METHODS: We examined OAS1 genotype distribution in 401 patients with MS, 394 healthy controls, and 178 patients with RRMS receiving interferon-beta (IFNbeta) assessed as 1) having no or minimal disease activity on IFNbeta, 2) having disease activity despite IFNbeta, and 3) 65 patients with RRMS with highly active disease. RESULTS: The OAS1 genotype distribution differed between patients with MS and controls (p = 0.000003), with lower frequency of GG homozygotes in patients with MS (6%) compared with controls (17%). In relation to disease severity, 34 (32%) patients with no or minimal disease activity on IFNbeta had the AA and 8 (8%) the GG genotype; of patients with disease activity despite IFNbeta, 27 (51%) were AA, while only 1 (2%) was GG (p = 0.03). Median time to first relapse on IFNbeta was 24 months in patients with RRMS with AA genotype and 33 months with AG or GG genotype (p = 0.04). The GG genotype was absent in 65 patients with highly active RRMS (p = 0.03). CONCLUSIONS: A functional OAS1 SNP, AA genotype, confers susceptibility to MS and the GG genotype may protect against increased disease activity.

    Sclerosis is a final substrate and outcome of structural lesions of different organs and tissues in various pathological conditions, such as hypertensive disease, coronaty heart disease, chronic obstructive pulmonary disease, systemic lupus erythematosus, rheumatoid arthritis, systemic scleroderma, etc. Not infrequently it as a determinant of severity and unfavourable outcome of the disease. Elucidation of general patterns of the development of sclerosis requires an integrated approach to the systemic analysis of clinical, genetic, biochemical, and morphological characteristics whereas a local analysis reveals peculiarities of formation of sclerosis in individual patients. Such combination permits to use methods of predictive-preventive personified medicine for planning the treatment of sclerosis.

    Full Text Available Sexual dysfunction is common in systemic sclerosis (SSc. Male erectile dysfunction (MED has been reported in around 80% of subjects and more than half of female patients fulfill criteria for diagnosis as female sexual arousal Disorder (FSAD. While some evidence supports a role for cavernosal fibrosis, abundant data suggest that MED is yet another clinical feature of SSc related to vasculopathy. The contribution of vasculopathy to the more complex issues of female sexual dysfunction is less clear. Inhibitors of Type V phosphodiesterase are effective in men with MED secondary to SSc. Limited study in women suggests inconsistent effects on behavior (frequency but not on measures related to perfusion. Sexual activity is an important component of quality of life and an important domain for the caregiver to address; it is not clear that it warrants primary consideration as a consistent measure of scleroderma-related vasculopathy.

  6. Registry Evaluation of Digital Ulcers in Systemic Sclerosis

    2010-01-01

    Full Text Available Digital ulcers are a very frequent complication of systemic sclerosis affecting about half of the SSc patients, and about 75% of the affected patients have their first DU episode within 5 years from their first non-Raynaud symptom. The lack of adequate classification criteria as well as the lack of knowledge of the development of DU have contributed to the opening of specific registries to better understand the natural history of these lesions. For these reason, specific disease registries play a fundamental role in this field of research. Thanks to the systematic collection of data and their subsequent analysis and comparison between different cohorts, it is possible to improve understanding of the underlying trigger mechanisms of DU development and to determine temporal trends. In the future, the development of recommendations for the management of DU remains of pivotal importance to prevent DU development and obtain rapid healing as well as reduction of pain and disability.

    Full Text Available The frequency of pericardial involvement in Systemic Sclerosis (SSc is high on autoptic or echocardiographic studies, but the clinical recognition of pericarditis with or without effusion is rare. We describe a case of a 71-year-old female with no previous history of heart disease, who presented with a large pericardial effusion and tamponade that required pericardial drain. She had suffered from Raynaud’s phenomenon since 25 years. Six weeks after hospital discharge she complained of skin hardening on left leg. Pericardial tamponade is a very rare manifestation of SSc and occurs both early or late in the course of the disease, but in our case it preceded the recognition of scleroderma. We have only identified two other cases of pericardial effusion preceding cutaneous involvement in scleroderma.

    Background: Faecal incontinence occurs in over one third of patients with systemic sclerosis. The aetiology is multifactorial. Conventional treatment is often unsuccessful. Sacral nerve stimulation is a new effective treatment for resistant faecal incontinence. Aims: To evaluate sacral nerve stimulation in patients with systemic sclerosis. Patients: Five women, median age 61 years (30–71), with scleroderma associated faecal incontinence were evaluated. All had failed maximal conventional treatment. Median number of preoperative weekly episodes of incontinence was 15 (7–25), median duration of incontinence was five years (5–9), and scleroderma 13 years (4–29). Methods: All patients were screened with temporary stimulation. Those who benefited underwent permanent implantation. At baseline and after stimulation a bowel diary, the SF-36 quality of life assessment, endoanal ultrasound, and anorectal physiology were performed. Results: Four patients were continent at a median follow up of 24 months (6–60). One patient failed temporary stimulation and was not permanently implanted. The weekly episodes of incontinence decreased from 15, 11, 23, and 7 to 0. Urgency resolved (median time to defer <1 minute (0–1) v 12.5 minutes (5–15)). Quality of life, especially social function, improved. Endoanal ultrasound showed an atrophic internal anal sphincter (median width 1.0 mm (0–1.6)). Anorectal physiology showed an increase in median resting pressure (37 pre v 65 cm H2O post) and squeeze pressure (89 v 105 cm H2O). Stimulation produced enhanced rectal sensitivity to distension. There were no major complications. Conclusions: Sacral nerve stimulation is a safe and effective treatment for resistant faecal incontinence secondary to scleroderma. The benefit is maintained in the medium term. PMID:12427794

    Objective To develop and assess the reliability and construct validity of a scale assessing disability involving the mouth in systemic sclerosis (SSc). Methods We generated a 34‐item provisional scale from mailed responses of patients (n = 74), expert consensus (n = 10) and literature analysis. A total of 71 other SSc patients were recruited. The test–retest reliability was assessed using the intraclass coefficient correlation and divergent validity using the Spearman correlation coefficient. Factor analysis followed by varimax rotation was performed to assess the factorial structure of the scale. Results The item reduction process retained 12 items with 5 levels of answers (total score range 0–48). The mean total score of the scale was 20.3 (SD 9.7). The test–retest reliability was 0.96. Divergent validity was confirmed for global disability (Health Assessment Questionnaire (HAQ), r = 0.33), hand function (Cochin Hand Function Scale, r = 0.37), inter‐incisor distance (r = −0.34), handicap (McMaster‐Toronto Arthritis questionnaire (MACTAR), r = 0.24), depression (Hospital Anxiety and Depression (HAD); HADd, r = 0.26) and anxiety (HADa, r = 0.17). Factor analysis extracted 3 factors with eigenvalues of 4.26, 1.76 and 1.47, explaining 63% of the variance. These 3 factors could be clinically characterised. The first factor (5 items) represents handicap induced by the reduction in mouth opening, the second (5 items) handicap induced by sicca syndrome and the third (2 items) aesthetic concerns. Conclusion We propose a new scale, the Mouth Handicap in Systemic Sclerosis (MHISS) scale, which has excellent reliability and good construct validity, and assesses specifically disability involving the mouth in patients with SSc.

    Erasmus' syndrome is the association between systemic sclerosis and silica exposure. We report a case of this syndrome in a driller-powderman exposed to silica and nitro compounds contained in explosives. Physiopathology and etiologies of systemic sclerosis are still not well known. However, nitric oxide, a product of nitro compounds metabolism, is involved in the physiopathology of the disease: it seems thus licit to wonder about the consequences of an uncontrolled occupational exposure to nitric oxide on the vascular function, already damaged by systemic sclerosis. To a wider extent, our report highlights the importance of a comprehensive and detailed collection of occupational exposures for patients diagnosed with systemic sclerosis.

    Systemic sclerosis is an autoimmune disease which shows extreme heterogeneity in its clinical presentation and that follows a variable and unpredictable course. Although some discrepancies in the incidence and prevalence rates between geographical regions may reflect methodological differences in the definition and verification of cases, they may also reflect true local differences. To determine the prevalence and incidence of systemic sclerosis in the city of Campo Grande, state capital of Mato Grosso do Sul (MS), Brazil, during the period from January to December 2014. All health care services of the city of Campo Grande - MS with attending in the specialty of Rheumatology were invited to participate in the study through a standardized form of clinical and socio-demographic assessment. Physicians of any specialty could report a suspected case of systemic sclerosis, but necessarily the definitive diagnosis should be established by a rheumatologist, in order to warrant the standardization of diagnostic criteria and exclusion of other diseases resembling systemic sclerosis. At the end of the study, 15 rheumatologists reported that they attended patients with systemic sclerosis and sent the completed forms containing epidemiological data of patients. The incidence rate of systemic sclerosis in Campo Grande for the year 2014 was 11.9 per million inhabitants and the prevalence rate was 105.6 per million inhabitants. Systemic sclerosis patients were mostly women, white, with a mean age of 50.58 years, showing the limited form of the disease with a mean duration of the disease of 8.19 years. Regarding laboratory tests, 94.4% were positive for antinuclear antibody, 41.6% for anti-centromere antibody and 19.1% for anti-Scl70; anti-RNA Polymerase III was performed in 37 patients, with 16.2% positive.

    Systemic sclerosis is a complex disease characterized by autoimmunity, vasculopathy and tissue fibrosis. Although most patients present with some degree of skin sclerosis, which is a distinguishing hallmark, the clinical presentation vary greatly complicating the diagnosis. In this regard, new classification criteria were jointly published in 2013 by American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR). A recent major development in the classification criteria is improved sensitivity, particularly for detecting early disease. The new criteria allow more cases to be classified as having systemic sclerosis (SSc), which leads to earlier treatment. Moreover it is clinically beneficial in preventing the disease progression with its irreversible fibrosis and organ damage. The aim of this review is to give insight into new classification criteria and current trends in the diagnosis of systemic sclerosis.

    Systemic Sclerosis (Ssc) is a complex disease of the connective tissue, characterized by progressive thickening and fibrosis of the skin and the internal organs and by diffused damage of the microvascular system. The fibrosis ones of the skin associated to the characteristic vascular alterations lead to the genesis of ulcers, more or less extended, often multiple, peripheral localization, chronic course, painful, able to influence patient's quality of life. Indeed, immunity reactivity, the thinning and the loss of elasticity of the skin, the peripheral neurological damage and the eventual drug assumption that can reduce regenerative/reparative abilities, can easily make an ulcer chronic and become infected complicating still more the patient disease, rendering more difficult the cure often, ulcer evolves to gangrene, and in some cases, in amputation too. For all these reasons, we have begun to study ulcers therapy (local and systemic), considering this activity it leave integrating of the charitable distance of the sclerodermic patient, putting to point on strategy both diagnostic and therapeutic, but above all with the primary scope, if possible, is to prevent ulcers, in contrary case, to alleviate the pain and to render the quality of the life of the patient better.

  20. Motor System Plasticity and Compensation in Multiple Sclerosis

    Full Text Available Multiple sclerosis (MS affects the central nervous system (CNS by inflammatory lesions, direct axonal injury, and by a rather diffuse and widespread neurodegeneration. For a long time, research has mainly focused on these destructive aspects of MS, while the compensatory effects of cellular repair and neural plasticity have received little consideration. However, as current effective immunomodulatory therapies may limit rather than preclude demyelination and axonal damage, additional therapeutic strategies promoting compensation of CNS damage might be of great use for preventing persistent impairment in MS. As a precondition for the development of such strategies, which may encompass pharmacological and behavioural interventions, but also non-invasive stimulation techniques, it seems fundamental to get deeper insights into the mechanisms of plasticity and adaptation at the systemic level. This review will provide a brief overview of what is known about plasticity of the motor system in patients with MS at present, with the main focus relying on evidence from functional imaging, neurophysiology, and motor learning. Overall, rapid-onset motor plasticity seems to be preserved even in advanced stages of the disease. Reorganisation processes, which can be shown early in the course of MS, are functionally relevant for motor compensation. In advanced MS, however, the brain´s adaptive reserve might be exhausted due to exceeding CNS injury. Future studies should address the question of how the later stages of central motor plasticity can be promoted best to preserve the patient´s autonomy for as long as possible.

    Systemic Sclerosis (SSc) is an autoimmune disorder characterized by microvascular injury and diffuse fibrosis of the skin and internal organs. While macrovascular disease and higher risk for cardiovascular events are well documented in other systemic rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus, the presence and extent of atherosclerosis among patients with SSc is yet to be established. Primary cardiac involvement, due to impairment of coronary microvascular circulation and myocardial fibrosis, considerably affects prognosis and life expectancy of individuals with SSc, representing one of the leading causes of death in this population. On the other hand the existence and prevalence of atherosclerotic coronary disease remains an issue of debate as studies comparing structural and morphological markers of atherosclerosis and cardiovascular events between SSc patients and the general population have yielded controversial results. The aim of this review is to summarize recent literature about the prevalence of cardiovascular disease in SSc, review the surrogate markers of CVD that have been evaluated and examine whether common pathogenic mechanisms exist between SSc and macrovascular disease.

    Full Text Available Systemic sclerosis (SSc is a chronic, multisystem connective tissue disease with protean clinical manifestations. Recent advances in understanding the pathogenic mechanisms have led to development of target-oriented and vasomodulatory drugs which play a pivotal role in treating various dermatological manifestations. An exhaustive literature search was done using Medline, Embase, and Cochrane library to review the recent concepts regarding pathogenesis and evidence-based treatment of salient dermatological manifestations. The concept of shared genetic risk factors for the development of autoimmune diseases is seen in SSc. It is divided into fibroproliferative and inflammatory groups based on genome-wide molecular profiling. Genetic, infectious, and environmental factors play a key role; vascular injury, fibrosis, and immune activation are the chief pathogenic factors. Vitamin D deficiency has been documented in SSc and correlates with the severity of skin involvement. Skin sclerosis, Raynaud′s phenomenon (RP with digital vasculopathies, pigmentation, calcinosis, and leg ulcers affect the patient′s quality of life. Immunosuppressives, biologicals, and hematopoietic stem cell transplantation are efficacious in skin sclerosis. Endothelin A receptor antagonists, calcium-channel blockers, angiotensin receptor inhibitors, prostacyclin analogs, and phosphodiesterase type 5 (PDE-5 inhibitors are the mainstay in RP and digital vasculopathies. Pigmentation in SSc has been attributed to melanogenic potential of endothelin-1 (ET-1; the role of ET 1 antagonists and vitamin D analogs needs to be investigated. Sexual dysfunction in both male and female patients has been attributed to vasculopathy and fibrosis, wherein PDE-5 inhibitors are found to be useful. The future concepts of treating SSc may be based on the gene expression signature.

    Full Text Available Introduction: Systemic sclerosis (SSc is a chronic autoimmune disease with very heterogeneous clinical manifestations. There are not many studies which directly research the pain experienced by patients with SSc. Aim: Evaluation of pain in patients with verified systemic sclerosis; making comparison in the two subsets of SSc (diffuse and limited and in the anti-centromere antibodies (ACA and anti-topoisomerase-I antibodies (ATA detected in patients. Material and methods: The study group included 42 patients with SSc. The research was conducted at the Institute of Rheumatology in Belgrade. Each patient was asked to complete the questionnaire, which included the questions about frequency, location and intensity of the pain. Two statistical methodologies were used in the data analysis: descriptive and analytical statistics. Results: Most of the patients (93% confirmed they had some kind of pain . Arthralgia was the most common pain symptom (78,6%, 29 (69% suffered from pain during Raynaud phenomenon, the back pain was found in 20 (47,6%, a headache in 13 (31%, the chest pain in 10 (23,8%, odynophagia in 9 (21,4% and in 8 (19% patients painful digital ulcers. The pain from digital ulcers was rated as the most intensive with the average value of 8,5/10. The patients with diffuse subset of SSc had a higher average intensity score of arthralgia (7,6, compared to those with limited SSc (5,5. The statistically significant difference in the frequency and intensity of the pain in the patients with anti-topoisomerase-I antibodies and the patients with anti-centromere antibodies was not found. Conclusion: Most of the patients suffer from some kind of pain. The most common pain was arthralgia, and the most intensive one was from digital ulcers, although it was the rarest. The pain frequency and intensity were not significantly different in patients with anti-topoisomerase-I and anti-centromere antibodies. There was a statisticaly significant difference in the

    Systemic sclerosis (SSc) is a chronic multi-system autoimmune disorder with gastrointestinal tract (GIT) involvement in up to 90% of patients and anorectal involvement occurs in up to 50% of patients. The pathogenesis of gastrointestinal abnormalities may be both myogenic and neurogenic. We aimed to identify which anorectal physiological abnormalities correlate with clinical symptoms and thus understand the pathophysiology of anorectal involvement in SSc. In total, 44 SSc patients (24 symptomatic (Sx) (fecal incontinence) and 20 asymptomatic (ASx)) and 20 incontinent controls (ICs) were studied. Patients underwent anorectal manometry, rectal mucosal blood flow (RMBF), rectal compliance (barostat), and rectoanal inhibitory reflex assessment (RAIR). Anal squeeze pressure was lower in the IC group compared with both the ASx and Sx groups (IC: 46.95 (30-63.9)) vs. ASx: 104.6 (81-128.3) vs. (Sx: 121.4 (101.3-141.6); P ASx: 6.7 (5.7-7.7) vs. IC: 8.5 (6.5-10.4); P ASx and in 1/20 IC patients. Fecal incontinence in SSc is related to neuropathy as suggested by absent RAIR and higher anal sensory threshold and is related less so to sphincter atrophy and rectal fibrosis.

    Full Text Available Abstract Background Systemic sclerosis (SSc is an autoimmune disorder of the connective tissue characterized by widespread vascular lesions and fibrosis. Little is known so far on the activation of the hemostatic and fibrinolytic systems in SSc, and most preliminary evidences are discordant. Methods To verify whether SSc patients might display a prothrombotic condition, plasma D-dimer was assessed in 28 consecutive SSc patients and in 33 control subjects, matched for age, sex and environmental habit. Results and discussion When compared to healthy controls, geometric mean and 95% confidence interval (IC95% of plasma D-dimer were significantly increased in SSc patients (362 ng/mL, IC 95%: 361–363 ng/mL vs 229 ng/mL, IC95%: 228–231 ng/mL, p = 0.005. After stratifying SSc patients according to disease subset, no significant differences were observed between those with limited cutaneous pattern and controls, whereas patients with diffuse cutaneous pattern displayed substantially increased values. No correlation was found between plasma D-dimer concentration and age, sex, autoantibody pattern, serum creatinine, erythrosedimentation rate, nailfold videocapillaroscopic pattern and pulmonary involvement. Conclusion We demonstrated that SSc patients with diffuse subset are characterized by increased plasma D-dimer values, reflecting a potential activation of both the hemostatic and fibrinolytic cascades, which might finally predispose these patients to thrombotic complications.

    Systemic sclerosis (SSc) is an inflammatory disease characterized by vascular abnormalities and fibrosis. The aim of the present study was to investigate the possible role of transient receptor potential melastatin (TRPM) channel genes in the susceptibility and phenotype expression of SSc. A total of 339 patients with SSc and 302 healthy controls were studied. Genomic DNA was extracted from leukocytes of the peripheral blood, and 25 single nucleotide polymorphisms in the TRPM channel genes were analyzed by the BioMark HD dynamic array system. There were marked increases in the CC genotype (94.7% vs 81.8%, pTRPM5 rs34551253 (Ala456Thr) polymorphism in SSc patients when compared to controls. TRPM3 gene rs1328142 polymorphism was also markedly associated with disease phenotype. However, no associations with the other 23 polymorphisms studied were found. This is the first study to examine the involvement of TRPM channel gene variations on the risk of SSc incidence. Our results suggest roles of TRPM3 and TRPM5 gene variants in the susceptibility to or clinical expression of SSc in the Turkish population.

    In vivo measurements of relaxation processes in multiple sclerosis (MS) lesions by magnetic resonance imaging (MRI) may be important for evaluation of the disease activity in individual MS plaques. To obtain information of presumably chronic plaques, 10 patients with severe, but stable MS were...... investigated, using a whole-body superconductive MR scanner, operating at 1.5 T. By employing 12-point (or 6-point) partial saturation inversion recovery (PSIR) and 32-echo multiple spin-echo sequences we measured T1 and T2 in MS plaques, white matter, and cortical gray matter.

    Systemic sclerosis (SSc) is characterized by wide-spread fibrosis, activation of immune system with production of autoantibodies and extensive vascular damage. Raynaud's phenomenon (RP) and digital ulcers (DU) represent two faces of the same coin in SSc vasculopathy. RP, the earliest manifestation of the vascular involvement, is due to an excessive vasospasm of digital arteries, precapillary arterioles and cutaneous arteriovenous shunts, usually in response to cold exposure or other stimuli. DU are a severe complication of microvessel involvement and also of the persistent vasospasm of RP. Thus, the management of RP and DU requires a multimodal approach using a combination of pharmacological, non-pharmacological, and surgical treatments. Currently, the treatment of these complications represents a great challenge for all physicians. Copyright © 2010 Elsevier B.V. All rights reserved.

  10. Screening for pulmonary arterial hypertension in systemic sclerosis

    2009-09-01

    Full Text Available The onset and progression of pulmonary arterial hypertension (PAH in patients with systemic sclerosis (SSc can be particularly aggressive; however, effective treatments are available. Therefore, early identification of patients with suspected PAH, confirmation of diagnosis, and intervention is essential. PAH may be challenging to diagnose in its earliest stages, particularly in populations that have multiple causes of breathlessness, and, therefore, screening is required. The optimal screening tools and methodology are, as yet, unknown, and this is confounded by a lack of consensus over which patients to screen. Current practice favours annual screening of all SSc patients using Doppler echocardiography to detect elevated right heart pressures. This will typically identify most patients with the various forms of pulmonary hypertension found in SSc. The optimum thresholds for Doppler echocardiography are still subject to investigation, especially for patients with mild pulmonary hypertension, and this technique may, therefore, yield a significant number of false-positives and a currently unknown number of false-negatives. Confirmatory right heart catheterisation remains necessary in all suspected cases. Further research is needed to identify the optimal tools and the screening approach with greatest specificity and selectivity.

    In a subgroup of patients with systemic sclerosis (SSc), vasospasm affecting the pulmonary circulation may contribute to worsening respiratory symptoms, including dyspnea. Noninvasive assessment of pulmonary blood flow (PBF), utilizing inert-gas rebreathing (IGR) and dual-energy computed-tomography pulmonary angiography (DE-CTPA), may be useful for identifying pulmonary vasospasm. Thirty-one participants (22 SSc patients and 9 healthy volunteers) underwent PBF assessment with IGR and DE-CTPA at baseline and after provocation with a cold-air inhalation challenge (CACh). Before the study investigations, participants were assigned to subgroups: group A included SSc patients who reported increased breathlessness after exposure to cold air (n = 11), group B included SSc patients without cold-air sensitivity (n = 11), and group C patients included the healthy volunteers. Median change in PBF from baseline was compared between groups A, B, and C after CACh. Compared with groups B and C, in group A there was a significant decline in median PBF from baseline at 10 minutes (-10%; range: -52.2% to 4.0%; P CACh. There was no significant difference in median PBF change between groups B or C at any time point and no change in pulmonary perfusion on DE-CTPA. Reduction in pulmonary blood flow following CACh suggests that pulmonary vasospasm may be present in a subgroup of patients with SSc and may contribute to worsening dyspnea on exposure to cold.

  12. Vascular Remodelling and Mesenchymal Transition in Systemic Sclerosis

    Directory of Open Access Journals (Sweden)

    Pier Andrea Nicolosi

    2016-01-01

    Full Text Available Fibrosis of the skin and of internal organs, autoimmunity, and vascular inflammation are hallmarks of Systemic Sclerosis (SSc. The injury and activation of endothelial cells, with hyperplasia of the intima and eventual obliteration of the vascular lumen, are early features of SSc. Reduced capillary blood flow coupled with deficient angiogenesis leads to chronic hypoxia and tissue ischemia, enforcing a positive feed-forward loop sustaining vascular remodelling, further exacerbated by extracellular matrix accumulation due to fibrosis. Despite numerous developments and a growing number of controlled clinical trials no treatment has been shown so far to alter SSc natural history, outlining the need of further investigation in the molecular pathways involved in the pathogenesis of the disease. We review some processes potentially involved in SSc vasculopathy, with attention to the possible effect of sustained vascular inflammation on the plasticity of vascular cells. Specifically we focus on mesenchymal transition, a key phenomenon in the cardiac and vascular development as well as in the remodelling of injured vessels. Recent work supports the role of transforming growth factor-beta, Wnt, and Notch signaling in these processes. Importantly, endothelial-mesenchymal transition may be reversible, possibly offering novel cues for treatment.

    Full Text Available Introduction : Systemic sclerosis (SSc is achronic connective tissue disease characterized by microangiopathy with inadequate angiogenesis. Angiostatin (AS is a potent antiangiogenic factor specifically inhibiting proliferation and inducing apoptosis of vascular endothelial cells. Aim : To evaluate the level of angiostatin in the serum of patients with SSc. Material and methods : Serum levels of AS were measured in 20 SSc patients and 12 healthy controls. Results : A statistically significant difference in the serum levels of AS in SSc patients was observed compared to the control group (636.51 vs. 869.20 ng/ml; p = 0.012. Significant correlations between limited and disseminated SSc (lSSc/dSSc were not found, however, a difference between lSSc and the control group was demonstrated (620.00 vs. 869.20 ng/ml; p = 0.011. The serum level of AS was not associated positively with organ changes caused by SSc. However, a statistically significant lower serum level of AS was observed in patients with SSc and no esophageal (p = 0.008 or pulmonary changes (p = 0.007 compared to the control group. Conclusions : Our results reveal significant differences in AS level in SSc patients compared to the healthy controls, and suggest that a low level of AS may occur as a result of impaired angiogenesis.

    2017-01-01

    Full Text Available Systemic sclerosis-associated pulmonary hypertension (SSc-PH and pulmonary arterial (PA hypertension (SSc-PAH are well-recognized manifestations. SSc-PH is a hemodynamic observation, and it is important to identify underlying etiology. SSc patients commonly have mixed etiology for SSc-PH due to interstitial lung disease, PAH, and left heart disease. SSc-PAH is associated with high morbidity and mortality. Early detection of PAH through routine screening improves survival in patients with SSc. Right heart catheterization is mandatory to diagnose PAH. SSc-PAH patients should be managed by a multidisciplinary team comprising of rheumatologist, pulmonologist, cardiologist, and physiotherapist. Various pharmacotherapy options to treat SSc-PAH are derived from the idiopathic PAH management. Upfront or sequential combination therapy of PAH-specific drugs seems to confer a clinical benefit compared to monotherapy. Cardiopulmonary rehabilitation should be considered as a part of the management plan. Lung transplantation is a consideration in patients who are not responding to pharmacotherapy. Although the long-term prognosis of SSc-PAH has been historically poor, the landscape is gradually changing with early detection and institution of treatment.

    Systemic sclerosis (SSc) is a connective tissue disease that results in excessive accumulation of collagen in the skin and internal organs. Overall, SSc is a rare disorder, but has a high mortality, particularly in last decade of life. To improve the survival rate, an accurate and early diagnosis is crucial. Currently, the modified Rodnan skin score (mRSS) is the gold standard for evaluating SSc progression based on clinical palpation at 17 sites on the body. However, this procedure can be time consuming, and the assessed score may be biased by the experience of the clinician, causing inter- and intraobserver variabilities. Moreover, the instrinsic elasticity of skin may further bias the mRSS assessment in the early stages of SSc, such as oedematous. To overcome these limitations, there is a need for a rapid, accurate, and objective assessment technique. Optical coherence elastography (OCE) is a novel, rapidly emerging technique, which can assess mechanical contrast in tissues with micrometer spatial resolution. In this work, we demonstrate the first use of OCE to assess the mechanical properties of control and SSc-like diseased skin non-invasively. A focused air-pulse induced an elastic wave in the skin, which was detected by a home-built OCE system. The elastic wave propagated significantly faster in SSc skin compared to healthy skin. The Young's modulus of the SSc skin was significantly higher than that of normal skin (P<0.05). Thus, OCE was able to objectively differentiate healthy and fibrotic skin completely noninvasively and is a promising and potentially useful new technology for quantifying skin involvement in SSc.

    To investigate if patients with Systemic Sclerosis (SSc) show a higher prevalence of neuropathic pain (NP) in comparison with controls. To study the relationship between clinical variables of the disease and NP among SSc patients. 48 patients and 45 controls were included. Presence of NP was assessed applying the DN4 "Douleur Neuropathique en 4 Questions" questionnaire. Different clinical variables were also assessed in patients. Statistical analysis included parametric, nonparametric tests and multivariate logistic regression. NP was significantly higher in SSc patients (56.2% vs 13.3%, pNP (pNP in SSc patients and controls. These findings should raise the awareness of the clinician to recognize and address the presence of NP in these patients, especially in those with severe skin involvement.

    Directory of Open Access Journals (Sweden)

    B. Ruaro

    2017-12-01

    Full Text Available Microvascular damage and a decrease in peripheral blood perfusion are typical features of systemic sclerosis (SSc with serious clinical implications, not only for a very early diagnosis, but also for disease progression. Nailfold videocapillaroscopy is a validated and safe imaging technique able to detect peripheral capillary morphology, as well as to classify and to score any nailfold abnormalities into different microangiopathy patterns. Capillaroscopic analysis is now included in the ACR/EULAR classification criteria for SSc. The decrease in peripheral blood perfusion is usually associated with microvascular damage in SSc, which may be studied by different methods. Several of these make use of safe laser technologies. This paper focuses on these new clinical aspects to assess SSc microvascular impairment.

    Several chronic inflammatory disorders, such as rheumatoid arthritis and idiopathic inflammatory myositis, have been shown to increase risk of ischemic stroke but the data on systemic sclerosis (SSc) remains unclear. We conducted a systematic review and meta-analysis of observational studies that reported odds ratio, relative risk, hazard ratio, or standardized incidence ratio comparing risk of ischemic stroke in patients with SSc versus non-SSc participants. Pooled risk ratio and 95% confidence intervals (CIs) were calculated using a random-effect, generic inverse variance method of DerSimonian and Laird. Four retrospective cohort studies were identified and included in our data analysis. We found a statistically significant elevated ischemic stroke risk in patients with SSc with a pooled risk ratio of 1.68 (95% CI, 1.26-2.24). The statistical heterogeneity was moderate with an I(2) of 69%. Our study demonstrated a statistically significant increased ischemic stroke risk among patients with SSc.

    This cross-sectional study aims to identify the predictors of work-related difficulties in a sample of employed persons with multiple sclerosis as addressed with the Multiple Sclerosis Questionnaire for Job Difficulties. Hierarchical linear regression analysis was conducted to identify predictors of work difficulties: predictors included demographic variables (age, formal education), disease duration and severity, perceived disability and psychological variables (cognitive dysfunction, depression and anxiety). The targets were the questionnaire's overall score and its six subscales. A total of 177 participants (108 females, aged 21-63) were recruited. Age, perceived disability and depression were direct and significant predictors of the questionnaire total score, and the final model explained 43.7% of its variation. The models built on the questionnaire's subscales show that perceived disability and depression were direct and significant predictors of most of its subscales. Our results show that, among patients with multiple sclerosis, those who were older, with higher perceived disability and higher depression symptoms have more and more severe work-related difficulties. The Multiple Sclerosis Questionnaire for Job Difficulties can be fruitfully exploited to plan tailored actions to limit the likelihood of near-future job loss in persons of working age with multiple sclerosis. Implications for rehabilitation Difficulties with work are common among people with multiple sclerosis and are usually addressed in terms of unemployment or job loss. The Multiple Sclerosis Questionnaire for Job Difficulties is a disease-specific questionnaire developed to address the amount and severity of work-related difficulties. We found that work-related difficulties were associated to older age, higher perceived disability and depressive symptoms. Mental health issues and perceived disability should be consistently included in future research targeting work-related difficulties.

    2016-08-01

    Full Text Available Disease-modifying drugs (DMDs such as interferon (IFN-β and glatiramer acetate are often prescribed to slow disability progression in patients with multiple sclerosis (MS. However, adverse pregnancy outcomes have been reported with these medications. We report the rare occurrence of severe placental complications in a 30-yearold pregnant woman with MS who continued to take IFN-β during her first trimester. She presented at the Tawam Hospital, Al Ain, United Arab Emirates, in 2013 with early-onset fetal growth restriction. At 30 gestational weeks, she developed severe pre-eclampsia. The baby was delivered via emergency Caesarean section and was discharged at the age of two months. Continuation of IFN-β during pregnancy may have contributed to the development of placental insufficiency in this patient. Increased education regarding the risks of DMDs for pregnant patients with MS is very important to ensure successful pregnancy outcomes.

    To characterize ultrasonographic (US) features in the hand of patients with systemic sclerosis (SSc) and to evaluate the sensitivity of US in the detection of calcinosis and acroosteolysis. The local ethics committee approved this study, and oral informed consent was obtained. A total of 44 consecutive patients with SSc (34 women; mean age, 56.1 years ± 12.1 [standard deviation]; 10 men; mean age, 45.0 years ± 14.0) and 30 healthy control subjects (20 women; mean age, 46.3 years ± 12.1; 10 men; mean age, 39.6 years ± 10.8) were included between October 2010 and December 2011. Bilateral US, including Doppler assessment of the wrists, hands, and fingers, was performed, and presence of synovitis, tenosynovitis with or without a layered appearance, calcifications, acroosteolysis, and distal vascularization was recorded. Radiography of both hands was performed to assess for acroosteolysis and calcinosis. Frequency of US features, sensitivity of US for calcinosis and acroosteolysis, and respective confidence intervals were calculated. Synovitis was found in 17 patients (39%). Tenosynovitis was found in 12 patients (27%), and it had a layered pattern in 15 (41%) of 37 cases. Calcinosis was found in 17 patients (39%) with US, with a sensitivity of 89%. Acroosteolysis was found in nine (20%) patients with US and in 10 (23%) patients with radiography, with 90% sensitivity for US. Distal vascularization was detected in 26 patients (59%) and 30 control subjects (100%) and was in contact with the acroosteolysis bed in seven (78%) of nine patients with SSc. US can be used to assess features of SSc, including synovitis, tenosynovitis, calcinosis, acroosteolysis, and distal vascularization and is sensitive for calcinosis and acroosteolysis detection. A layered pattern (similar to the appearance of an artichoke heart) of tenosynovitis was seen commonly. Online supplemental material is available for this article. © RSNA, 2013.

    The effect of systemic sclerosis (SSc) on bone density is not well understood. Through systematic review of the literature, the objectives of this study were to synthesize data about the prevalence of low bone mineral density (BMD), risk factors for low BMD, and occurrence of fracture and fracture-related mortality in SSc. A search was conducted of MEDLINE (1948-2012), Evidence Based Medicine Reviews (1991-2012), EMBASE (1980-2012), and CINAHL (1981-2012). Abstracts were screened to identify studies that evaluated low BMD in patients with SSc. Two investigators independently used a standardized form to abstract prevalence of osteopenia and osteoporosis (OP); risk factors for low BMD, BMD measurements, frequency of fracture, and fracture-related mortality. Screening of 1032 citations identified 19 articles. Fifteen studies compared patients with SSc to controls. Most patients were white, female (prevalence 74%-100%), and postmenopausal (prevalence 45.9%-100%). The prevalence of low BMD and OP was 27%-53.3% and 3%-51.1%, respectively. Ten studies reported a lower BMD in patients with SSc compared to matched controls, whereas 2 studies reported no difference. Candidate risk factors for low BMD in SSc include family history of OP, age, menopause, diffuse subtype, presence of internal organ involvement, low vitamin D levels, and calcinosis. However, the studies supporting these factors were conflicting. Fracture rate ranged between 0% and 38%. No study reported OP-related fracture mortality. The data suggest that patients with SSc are at risk of low BMD and fracture, especially when other risk factors for OP are present. The interaction of SSc manifestations, traditional OP risk factors, and clinically relevant outcomes is complex and warrants further research.

    Objective To evaluate whether the systemic sclerosis (SSc)-associated IRAK1 non-synonymous single-nucleotide polymorphism rs1059702 is responsible for the Xq28 association with SSc or whether there are other independent signals in the nearby methyl-CpG-binding protein 2 gene (MECP2). Methods We analysed a total of 3065 women with SSc and 2630 unaffected controls from five independent Caucasian cohorts. Four tag single-nucleotide polymorphisms of MECP2 (rs3027935, rs17435, rs5987201 and rs5945175) and the IRAK1 variant rs1059702 were genotyped using TaqMan predesigned assays. A meta-analysis including all cohorts was performed to test the overall effect of these Xq28 polymorphisms on SSc. Results IRAK1 rs1059702 and MECP2 rs17435 were associated specifically with diffuse cutaneous SSc (PFDR=4.12×10−3, OR=1.27, 95% CI 1.09 to 1.47, and PFDR=5.26×10−4, OR=1.30, 95% CI 1.14 to 1.48, respectively), but conditional logistic regression analysis showed that the association of IRAK1 rs1059702 with this subtype was explained by that of MECP2 rs17435. On the other hand, IRAK1 rs1059702 was consistently associated with presence of pulmonary fibrosis (PF), because statistical significance was observed when comparing SSc patients PF+ versus controls (PFDR=0.039, OR=1.30, 95% CI 1.07 to 1.58) and SSc patients PF+ versus SSc patients PF− (p=0.025, OR=1.26, 95% CI 1.03 to 1.55). Conclusions Our data clearly suggest the existence of two independent signals within the Xq28 region, one located in IRAK1 related to PF and another in MECP2 related to diffuse cutaneous SSc, indicating that both genes may have an impact on the clinical outcome of the disease.

    Highlights: Black-Right-Pointing-Pointer ABA is an endogenous hormone in humans, regulating different cell responses. Black-Right-Pointing-Pointer ABA reverts some of the functions altered in SSc fibroblasts to a normal phenotype. Black-Right-Pointing-Pointer UV-B irradiation increases ABA content in SSc cultures. Black-Right-Pointing-Pointer SSc fibroblasts could benefit from exposure to ABA and/or to UV-B. -- Abstract: The phytohormone abscisic acid (ABA) has been recently identified as an endogenous hormone in humans, regulating different cell functions, including inflammatory processes, insulin release and glucose uptake. Systemic sclerosis (SSc) is a chronic inflammatory disease resulting in fibrosis of skin and internal organs. In this study, we investigated the effect of exogenous ABA on fibroblasts obtained from healthy subjects and from SSc patients. Migration of control fibroblasts induced by ABA was comparable to that induced by transforming growth factor-{beta} (TGF-{beta}). Conversely, migration toward ABA, but not toward TGF-{beta}, was impaired in SSc fibroblasts. In addition, ABA increased cell proliferation in fibroblasts from SSc patients, but not from healthy subjects. Most importantly, presence of ABA significantly decreased collagen deposition by SSc fibroblasts, at the same time increasing matrix metalloproteinase-1 activity and decreasing the expression level of tissue inhibitor of metalloproteinase (TIMP-1). Thus, exogenously added ABA appeared to revert some of the functions altered in SSc fibroblasts to a normal phenotype. Interestingly, ABA levels in plasma from SSc patients were found to be significantly lower than in healthy subjects. UV-B irradiation induced an almost 3-fold increase in ABA content in SSc cultures. Altogether, these results suggest that the fibrotic skin lesions in SSc patients could benefit from exposure to high(er) ABA levels.

    To evaluate the relationship between mortality and nutritional risk associated with disease activity in Systemic Sclerosis (SSc). A single-centre prospective cohort study involving 160 SSc outpatients (median age, 62 years [25th-75th, 54-68]). Nutritional risk was assessed by the Malnutrition Universal Screening Tool (MUST), a screening tool that combines anthropometric parameters of nutritional status (body mass index [BMI] and percentage of unintentional weight loss [WL]) with the presence of an "acute disease" (as defined by a disease activity score ≥3 according to Valentini's criteria). Prevalence of high nutritional risk (MUST score ≥2) was 24.4% [95%CI, 17.4-31.3]. A low nutritional risk (MUST = 1) was detected in 30% of our study sample. In hazard analysis (median follow-up duration = 46 months [25th-75th percentile, 31-54]), high nutritional risk was significantly associated with mortality (HR = 8.3 [95%CI, 2.1-32.1]). The performance of the model based on nutritional risk including disease activity (Harrell's c = 0.74 [95%CI, 0.59-0.89]) was superior to that based on active disease alone (HR = 6.3 [95%CI, 1.8-21.7]; Harrell's c = 0.68 [95%CI, 0.53-0.84]). Risk scored only by anthropometric parameters (prevalence, 9.4% [95%CI, 4.6-14.2]) was not associated with mortality: HR = 2.8 [95%CI, 0.6-13.2]. In SSc outpatients MUST significantly predicts mortality. The combined assessment of nutritional parameters and disease activity significantly improves the evaluation of mortality risk. Disease-related nutritional risk screening should be systematically included in the clinical workup of every SSc patient.

    Pulmonary arterial hypertension (PAH) complicates the course of systemic sclerosis (SSc) and is associated with poor prognosis. The elevation of systolic pulmonary arterial pressure (sPAP) during exercise in patients with SSc with normal resting haemodynamics may anticipate the development of PAH. Exercise echocardiography (ExEcho) has been proposed as a useful technique to identify exercise-induced increases in sPAP, but it is unclear how to clinically interpret these findings. In this systematic review, we summarize the available evidence on the role of exercise echocardiography to estimate exercise-induced elevations in pulmonary and left heart filling pressures in patients with systemic sclerosis. We conducted a systematic review of the literature using MEDLINE, Cochrane Library and Web of Knowledge, using the vocabulary terms: ('systemic sclerosis' OR 'scleroderma') AND ('exercise echocardiography') AND ('pulmonary hypertension'). Studies including patients with SSc without a prior diagnosis of PAH, and subjected to exercise echocardiography were included. All searches were limited to English and were augmented by review of bibliographic references from the included studies. The quality of evidence was assessed by the Effective Public Health Practice Project system. We identified 15 studies enrolling 1242 patients, who were mostly middle-aged and female. Several exercise methods were used (cycloergometer, treadmill and Master's two step), with different protocols and positions (supine, semi-supine, upright); definition of a positive test also varied widely. Resting estimated sPAP levels varied from 18 to 35 mm Hg, all in the normal range. The weighted means for estimated sPAP were 22.2 ± 2.9 mmHg at rest and 43.0 ± 4.3 mmHg on exercise; more than half of the studies reported mean exercise sPAP ≥40 mmHg. The assessment of left ventricular diastolic function on peak exercise was reported in a minority of studies; however, when assessed, surrogate

    Systemic sclerosis and morphea are connective tissue diseases characterized by tightening, thickening, and hardening of the skin, leading to significant morbidity. Unfortunately, current treatment options have limited efficacy for many patients. Cutaneous manifestations of these diseases arise from excess collagen deposition and fibrosis in the skin, through pathogenic mechanisms which have yet to be extensively detailed at the causal immune and cellular levels. Research elucidating the mechanism of action of retinoic acid on collagen production in the skin and case series highlighting the success of retinoic acid on the skin manifestations of systemic sclerosis and on morphea demonstrate its promise as a treatment. Herein they will briefly review the treatment options for both systemic sclerosis and morphea, and will discuss the potential of retinoic acid as a therapy and the supporting evidence from the literature, highlighting the previously published basic science and clinical studies investigating the role of retinoic acid in the treatment of sclerotic skin diseases. © 2016 Wiley Periodicals, Inc.

    An increasing body of evidence suggests that cannabinoids have beneficial effects on the symptoms of multiple sclerosis, including spasticity and pain. Endogenous molecules with cannabinoid-like activity, such as the "endocannabinoids", have been shown to mimic the anti-inflammatory properties of cannabinoids through the cannabinoid receptors. Several studies suggest that cannabinoids and endocannabinoids may have a key role in the pathogenesis and therapy of multiple sclerosis. Indeed, they can down regulate the production of pathogenic T helper 1-associated cytokines enhancing the production of T helper 2-associated protective cytokines. A shift towards T helper 2 has been associated with therapeutic benefit in multiple sclerosis. In addition, cannabinoids exert a neuromodulatory effect on neurotransmitters and hormones involved in the neurodegenerative phase of the disease. In vivo studies using mice with experimental allergic encephalomyelitis, an animal model of multiple sclerosis, suggest that the increase of the circulating levels of endocannabinoids might have a therapeutic effect, and that agonists of endocannabinoids with low psychoactive effects could open new strategies for the treatment of multiple sclerosis.

    Full Text Available Background. Systemic sclerosis (SSc is characterized by endothelial dysfunction and widespread microangiopathy. However, a macrovascular damage could be also associated. Aortic pulse wave velocity (aPWV is known to be a reliable indicator of arterial stiffness and a useful prognostic predictor of cardiovascular events. Moreover, aPWV may be easily measured by non-invasive, user-friendly tool. Aim of our study was to evaluate aPWV alterations in a series of SSc patients. Methods. The aPWV was evaluated in 35 consecutive female SSc patients and 26 sex- and age-matched healthy controls. aPWV alterations were correlated with cardiopulmonary involvement. Results. A significant increase of aPWV was observed in SSc patients compared to controls (9.4±3.2 m/s vs 7.3±1 m/s; P=0.002. In particular, 14/35 (40% SSc patients and only 1/26 (4% controls (P=0.0009 showed increased aPWV (>9 m/s cut-off value. Moreover, echocardiography evaluation showed an increased prevalence of right atrial and ventricular dilatation (atrial volume: 23.6±6.2 mL vs 20.3±4.3 mL, P=0.026; ventricular diameter 19.5±4.9 mm vs 15.9±1.6 mm; P=0.001 associated to higher values of pulmonary arterial systolic pressure (PAPs in SSc patients (31.5±10.4 mmHg vs 21.6±2.9 mmHg; P50 years old. Furthermore, altered aPWV was more frequently associated with limited cutaneous pattern, longer disease duration (≥5 years, and/or presence of anticentromere antibody (ACA. Conclusions. A significantly higher prevalence of abnormally increased aPWV was evidenced in SSc patients compared to healthy controls. The possibility of more pronounced and diffuse vascular damage in a particular SSc subset (ACA-positive subjects with limited cutaneous scleroderma and longer disease duration might be raised.

  1. Hand Impairment in Systemic Sclerosis: Various Manifestations and Currently Available Treatment.

    2016-09-01

    Systemic sclerosis (SSc) is an autoimmune disease initially recognized by hand involvement due to characteristic Raynaud's phenomenon (RP), puffy hands, skin thickening, and contractures resembling claw deformities. SSc contributes to hand impairment through inflammatory arthritis, joint contractures, tendon friction rubs (TFRs), RP, digital ulcers (DU), puffy hands, skin sclerosis, acro-osteolysis, and calcinosis. These manifestations, which often co-exist, can contribute to difficulty with occupational activities and activities of daily living (ADL), which can result in impaired quality of life. However, despite this knowledge, most diagnostic and treatment principles in SSc are focused on visceral manifestations due to known associations with morbidity and mortality. Treatment of inflammatory arthritis is symptom based and involves corticosteroids ≤10mg daily, methotrexate, tumor necrosis factor inhibitors, tocilizumab, and abatacept. Small joint contractures are managed by principles of occupational hand therapy and rarely surgical procedures. TFRs may be treated similar to inflammatory arthritis with corticosteroids. All patients with RP and DU should keep digits covered and warm and avoid vasoconstrictive agents. Pharmacologic management of RP begins with use of calcium channel blockers, but additional agents that may be considered are fluoxetine and phosphodiesterase 5 (PDE5) inhibitors. DU management also involves vasodilators including calcium channel blockers and PDE5 inhibitors; bosentan has also been shown to prevent DU. In patients with severe RP and active DU, intravenous epoprostenol or iloprost can be used and surgical procedures, such as botulinum injections and digital sympathectomies, may be considered. For those with early diffuse cutaneous SSc needing immunosuppression for skin sclerosis, methotrexate or mycophenolate mofetil can be used, but the agent of choice depends on co-existing manifestations, such as inflammatory arthritis and/or lung

    Fatigue is one of the most common and troubling symptoms of multiple sclerosis (MS) and more severe and disabling than fatigue in other somatic populations. Although fatigue seems MS specific, its pathogenesis is still poorly understood. To study the disease specificity of fatigue in MS by comparing its level, its physical and psychological correlates to those of patients with ulcerative colitis (UC), a peripheral chronic auto-immune disease. We focused on the relative contribution of disease severity, depression and negative affectivity to fatigue in both patient samples. A total of 88 MS and 76 UC patients were included in this cross-sectional study. Fatigue, depression and negative affectivity were assessed respectively with the physical and mental fatigue subscales of the Multidimensional Fatigue Inventory, the depression subscale of the Hospital Anxiety and Depression Scale, and the neuroticism subscale of the Dutch NEO Five-Factor Inventory. The Expanded Disability Status Scale and the Colitis Activity Index were used to measure disease severity in MS and UC patients respectively. While levels of both physical and mental fatigue were significantly higher in MS patients than in UC patients, there were no group differences in the contribution of disease severity, depression and negative affectivity to both physical and mental fatigue. Although levels of fatigue are higher for MS patients when compared with UC patients, the correlates of fatigue do not indicate MS specificity. As such our results support a transdiagnostic approach to fatigue in MS. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    Cathy J Jensen

    Full Text Available Recent association studies in multiple sclerosis (MS have identified and replicated several single nucleotide polymorphism (SNP susceptibility loci including CLEC16A, IL2RA, IL7R, RPL5, CD58, CD40 and chromosome 12q13-14 in addition to the well established allele HLA-DR15. There is potential that these genetic susceptibility factors could also modulate MS disease severity, as demonstrated previously for the MS risk allele HLA-DR15. We investigated this hypothesis in a cohort of 1006 well characterised MS patients from South-Eastern Australia. We tested the MS-associated SNPs for association with five measures of disease severity incorporating disability, age of onset, cognition and brain atrophy. We observed trends towards association between the RPL5 risk SNP and time between first demyelinating event and relapse, and between the CD40 risk SNP and symbol digit test score. No associations were significant after correction for multiple testing. We found no evidence for the hypothesis that these new MS disease risk-associated SNPs influence disease severity.

    Exercise training is one strategy for improving cardiorespiratory fitness (CRF) in multiple sclerosis (MS); however, few modalities are accessible for those with severe mobility impairment. Functional electrical stimulation (FES) cycling is an adapted exercise modality with the potential for improving CRF in people with severe MS. The objective of this study was to characterize the cardiorespiratory response of acute voluntary cycling with FES in people with MS with severe mobility impairment, and to compare this response to passive leg cycling. Eleven participants with MS that required assistance for ambulation completed a single bout of voluntary cycling with FES or passive leg cycling. Oxygen consumption, heart rate (HR), work rate (WR), and ratings of perceived exertion (RPE) were recorded throughout the session. For the FES group, mean exercising oxygen consumption was 8.7 ± 1.8 mL/(kg·min) -1 , or 63.5% of peak oxygen consumption. Mean HR was 102 ± 9.7 bpm, approximately 76.4% of peak HR. Mean WR was 27.0 ± 9.2 W, or 57.3% of peak WR, and median RPE was 13.5 (interquartile range = 5.5). Active cycling with FES was significantly (p cycling based on oxygen consumption, HR, WR, and RPE during exercise. In conclusion, voluntary cycling with FES elicited an acute response that corresponded with moderate-to vigorous-intensity activity, suggesting that active cycling with FES can elicit a sufficient stimulus for improving CRF.

    Beyond the production of autoantibodies, B-cells are thought to play a role in systemic sclerosis (SSc) by secreting proinflammatory/profibrotic cytokines. B-cells are a heterogeneous population with different subsets distinguished by their phenotypes and cytokine production. Data about B-cell subsets, cytokine production and intracellular pathways leading to this production are scarce in SSc. The aim of our study was to describe B-cell homeostasis, activation, proliferation, cytokine production in B-cells and serum and B-cell intracellular signaling pathways in SSc. We hypothezided that B-cell homeostasis and cytokine production were altered in SSc and could be explained by serum cytokine as well as by intracellular signaling pathway abnormalities. Forty SSc patients and 20 healthy controls (HC) were prospectively included. B-cell subsets were determined by flow cytometry using CD19, CD21, CD24, CD38, CD27, IgM and IgD. CD25, CD80, CD95, HLA-DR were used to assess B-cell activation. Intracellular production of IL-10 and IL-6 were assessed by flow cytometry after TLR9 and CD40 stimulation. IL-6, IL-10, Ki67, Bcl2 mRNA were quantified in B-cells. Cytokine production was also assessed in sera and supernatants of B-cell culture, using a multiplex approach. Signaling pathways were studied through phosphorylation of mTOR, ERK, STAT3, STAT5 using a flow cytometry approach. We found that SSc patients exhibited an altered peripheral blood B-cell subset distribution, with decreased memory B-cells but increased proportion of naive and CD21 Lo CD38 Lo B-cell subsets. We observed an increased expression of activation markers (CD80, CD95, HLA-DR) on some B-cell subsets, mainly the memory B-cells. Secretion of IL-6, BAFF and CXCL13 were increased in SSc sera. There was no correlation between the peripheral blood B-cell subsets and the serum concentrations of these cytokines. After stimulation, we observed a lower proportion of IL-10 and IL-6 producing B-cells in SSc. Finally, we

    To determine the challenges experienced by women with systemic sclerosis, whose hands affected, while performing activities of daily living and their coping strategies. Many of the patients with systemic sclerosis experience difficulties in performing daily activities. One of the most important reasons for that is the impaired hand function due to their diseases. A descriptive cross-sectional design was conducted and questionnaire was used in this study. The study was performed in a Rheumatology Department at a tertiary-care hospital in Turkey between April 2010-December 2011. Nineteen patients with systemic sclerosis with hand involvement were enrolled in this study. The data were collected by using both a demographic data form and an Evaluation of Daily Activity Questionnaire. According to Evaluation of Daily Activity Questionnaire, the most scored dimension that patients can do with much difficulty was 'eating' and the dimension that patients unable to do was 'washing/clothes care'. In 'eating' dimension, the most difficult activities were 'opening glass jar', 'opening juice bottle' and 'opening bottle' that requiring the movement of rotation. Their coping strategies for these activities were as follows: try to open with a towel, try to remove the edge of the palm with a knife, use the hand palm and help from someone else (spouse, neighbour, etc.). In 'washing/clothes care' dimension, the most difficult activities were 'turning up hem of a skirt', 'washing up in bowl' and 'cutting out material'. For these activities, they use some coping strategies such as getting help from tailor, washing in the machine instead of hand washing. This study demonstrates that impaired hand function affects the daily life activities of patients with systemic sclerosis, and patients have developed some coping strategies to overcome these difficulties. The coping strategies used by patients can be helpful for the other patients with systemic sclerosis. © 2013 John Wiley & Sons Ltd.

    The interplay between genetic and environmental factors is likely involved in the pathogenesis of systemic sclerosis (SSc). Interstitial lung disease associated in the context of SSc (SSc-ILD) is associated with significant morbidity, and is the leading cause of death in SSc. The spectrum of SSc-ILD severity is wide, ranging from patients with only limited and inherently stable pulmonary involvement, to those with extensive and progressive pulmonary fibrosis. In order to provide accurate prognostic information for patients, and to initiate appropriate monitoring and treatment regimens, the ability to identify patients at risk of developing severe ILD early in the disease course is crucial. Identification of genetic variants involved in disease pathogenesis can not only potentially provide diagnostic/prognostic markers, but can also highlight dysregulated molecular pathways for therapeutic targeting. A number of genetic associations have been established for susceptibility to SSc, but far fewer studies have investigated genetic susceptibility to SSc-ILD specifically. In this review we present a summary of the studies assessing genetic associations with SSc-ILD.

    Localized scleroderma (LSc) primarily affects skin, whereas systemic sclerosis (SSc) affects skin and various internal organs. LSc and SSc are considered to be basically different diseases, and there is no transition between them. However, LSc and SSc have several common characteristics, including endothelial cell dysfunction, immune activation, and excess fibrosis of the skin, and there exist several SSc cases complicated with LSc during the course of SSc. Clinical and laboratory characteristics of SSc patients with LSc remain unclear. We investigated the clinical and laboratory features of 8 SSc patients with LSc among 220 SSc patients (3.6%). The types of LSc included plaque (5/8), guttate (2/8), and linear type (1/8). All cases were diagnosed as having SSc within 5 years before or after the appearance of LSc. In three cases of SSc with LSc (37.5%), LSc skin lesions preceded clinical symptoms of SSc. Young age, negative antinuclear antibody, and positive anti-RNA polymerase III antibody were significantly prevalent in SSc patients with LSc. The positivity of anticentromere antibody tended to be prevalent in SSc patients without LSc. No significant difference in the frequency of complications, such as interstitial lung disease, reflux esophagitis, and pulmonary artery hypertension, was observed. The awareness of these characteristic of SSc with LSc are essential to establish an early diagnosis and treatment. © 2015 Japanese Dermatological Association.

The presence of DUs may cause severe pain and often lead to impairment of patient’s functional activities and health-related quality of life. Moreover, poor patient cooperation during the wound care procedure due to pain may be associated with a negative outcome of DU healing. Therefore, pain management has a key role in patients with SSc. These two case reports describe the effectiveness and safety of oxycodone/naloxone in patients with SSc complicated by painful chronic DUs. Such a therapy has provided pain relief and consequently an increased compliance during redressing wounds.

    Limited data suggest that multiple sclerosis (MS) in Latin America (LA) could be less severe than in the rest of the world. The objective was to compare the course of MS between LA and other regions. Methods Centers from 18 countries with >20 cases enrolled in the MSBase Registry participated. Patients with MS with a disease duration of >1 year and <30 years at time of EDSS measurement were evaluated. The MS Severity Score (MSSS) was used as a measure of disease progression. Comparisons among regions (North America, Europe, Australia and LA), hemispheres and countries were performed. Results A total of 9610 patients were included. Patients were from: Europe, 6290 (65.6%); North America, 1609 (16.7%); Australia, 1119 (11.6%); and LA, 592 (6.1%). The mean MSSS in patients from LA was 4.47 ± 2.8, 4.53 ± 2.8 in North America, 4.51 ± 2.8 in Europe and 4.49 ± 2.7 in Australia. Mean MSSS in the northern hemisphere was 4.51 ± 1.6 compared to 4.48 ± 1.9 in the southern hemisphere. No differences were found for MSSS among hemispheres (p = 0.68), regions (p = 0.96) or countries (p = 0.50). Conclusions Our analyses did not discover any difference in mean MSSS among patients from different regions, hemispheres or countries. PMID:28607702

    judged each speech sample using the perceptual construct of Speech Severity using a visual analog scale. Additional measures obtained to describe participants included the Sentence Intelligibility Test (SIT), the 10-item Communication Participation Item Bank (CPIB), and standard biopsychosocial measures of depression (Beck Depression Inventory-Fast Screen; BDI-FS), fatigue (Fatigue Severity Scale; FSS), and overall disease severity (Expanded Disability Status Scale; EDSS). Healthy controls completed all measures, with the exception of the CPIB and EDSS. All data were analyzed using standard, descriptive and parametric statistics. For the MSCI group, the relationship between neuropsychological test scores and speech-language variables were explored for each speech task using Pearson correlations. The relationship between neuropsychological test scores and Speech Severity also was explored. Results and Discussion: Topic familiarity for descriptive discourse did not strongly influence speech production or perceptual variables; however, results indicated predicted task-related differences for some spoken language measures. With the exception of the MSCI group, all speaker groups produced the same or slower global speech timing (i.e., speech and articulatory rates), more silent and filled pauses, more grammatical and longer silent pause durations in spontaneous discourse compared to reading aloud. Results revealed no appreciable task differences for linguistic complexity measures. Results indicated group differences for speech rate. The MSCI group produced significantly faster speech rates compared to the MSDYS group. Both the MSDYS and the MSCI groups were judged to have significantly poorer perceived Speech Severity compared to typically aging adults. The Task x Group interaction was only significant for the number of silent pauses. The MSDYS group produced fewer silent pauses in spontaneous speech and more silent pauses in the reading task compared to other groups. Finally

    Rituximab (RTX) is a monoclonal chimeric antibody directed against the CD20 antigen of B lymphocytes. Late onset neutropenia (LON) is a recognised complication of rituximab usually occurring 4 weeks after the last dose and is reported in both haematological and rheumatological conditions. However, it has never been described in a patient with myositis and systemic sclerosis overlap disease. We describe a case of LON in a 54-year-old man who was diagnosed with myositis and then systemic sclerosis overlap disease. It resolved within 7 days, and the patient did not suffer neutropenic sepsis or any other complications. We propose similar mechanisms for LON as described in other conditions and routine blood monitoring in such patients.

    Silica-associated systemic sclerosis can occur in persons using calcined diatomaceous earth for filtration purpose. A limited systemic sclerosis was diagnosed in a 52-year-old male winegrower who had a combination of Raynaud's phenomenon, oesophageal dysfunction, sclerodactyly and telangectasia. The anti-centromere antibodies titre was 1/5000. The patient was frequently exposed to high atmospheric concentrations of calcined diatomaceous earth when performing the filtration of wines. Calcined diatomaceous earth is almost pure crystalline silica under the cristobalite form. The diagnosis of silica-associated limited systemic sclerosis after exposure to calcined diatomaceous earth was made. The patient's disease met the medical, administrative and occupational criteria given in the occupational diseases list 22 bis of the agriculture Social Security scheme and thence was presumed to be occupational in origin, without need to be proved. The diagnosis of occupational disease had been recognized by the compensation system of the agricultural health insurance. Copyright © 2010 Société française de rhumatologie.

    Fingolimod withdrawal may trigger the return of pretreatment disease activity. It is difficult to identify patients at risk of disease reactivation. We compared the demographic and clinical features of patients experiencing severe disease reactivation (SDR) after fingolimod cessation with those of patients who did not. All patients who commenced fingolimod and who continued therapy for at least 6 months were included. The demographic and clinical features of the 2 groups (SDR vs. no SDR) were assessed. Forty-four of 303 patients discontinued fingolimod for various reasons. Among these, 31 fulfilled our inclusion criteria and 8 (25.8%) exhibited SDR after drug cessation. The mean time for SDR was 2.6 months (range, 2 to 3 mo). The annualized relapse rate before fingolimod therapy was higher in the SDR than in the non-SDR group (1.59 vs. 0.81) (P=0.018). Although statistical significance was not attained, the mean Expanded Disability Status Scale score at the time of fingolimod cessation was higher in the non-SDR than in the SDR group (2.5 vs. 1.12) (P=0.074). SDR may develop within the first 3 months after cessation of fingolimod. Patients with higher annualized relapse rates and lower Expanded Disability Status Scale scores before commencing fingolimod treatment were more likely to exhibit SDR.

    To assess bone mass in women with systemic sclerosis (SSc) in comparison to age and sex-matched patients with rheumatoid arthritis (RA), and to evaluate factors influencing bone mineral density (BMD). Patients were consecutively recruited and assessed for BMD at the lumbar spine and hip by dual-energy X-ray absorptiometry (DEXA) using a densitometer. In SSc, the extent of skin involvement, modified Rodnan skin thickness score (mRSS) and Medsger disease severity index were assessed. Forty-three patients with SSc and 38 age-matched patients with RA were included. There was no difference in BMD measurements between patients with diffuse or limited SSc. Patients with SSc had similar risk factors associated with osteoporosis (OP) or low bone mass except for low body mass index (BMI) and low vitamin D levels compared to patients with RA. Lumbar spinal BMD and T score were similar between groups. Total hip and femoral neck BMD and T score at femoral neck and total hip were significantly lower in patient with SSc versus RA. There was significant association between mRSS, Medsger severity score (peripheral vascular involvement and skin) and femoral BMD. There is an increased risk for bone loss in patients with SSc and the risk of OP is associated with disease severity, prolonged menopause and disease duration. The complex pathophysiology of bone metabolism as well as complex pathogenesis of the SSc pose some difficulty reaching clear-cut conclusions on the causal relationship between SSc and bone loss. © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    Twenty patients with Progressive Systemic Sclerosis are studied by scintigraphic methodology. The esophageal transit method is used for liquid and solid meals. The results are compared with the ones of a control group, without or not gastrintestinal problems but without autoimmune diasese. 99 sup(m)Tc-sulfurcolloid is used as labelling compound. The studies were done in supine and orthostatical position. (M.A.C.) [pt

  8. Cytokine concentrations in serum and bronchoalveolar lavage as marker for pathogenesis and prognosis in systemic sclerosis

    OpenAIRE

    2010-01-01

    Systemic sclerosis (SSc) is a rare connective tissue disease characterized by increased production of extracellular matrix, endothelial dysfunction and immunity abnormalities. SSc is considered as a devastating multiorgan disease of unknown etiology with an autoimmunological background. In the present work we have measured levels of cytokines and chemokines in bronchoalveolar lavage fluid (BALF) and serum in cohorts of Ssc-patients, patients with other lung diseases and healthy donors. We...

    The efficacy and safety of botulinum toxin B (BTX-B) for treatment of Raynaud's phenomenon and digital ulcers in patients with systemic sclerosis was assessed. A total of 45 patients with systemic sclerosis who had Raynaud's phenomenon were blinded and divided randomly into 4 groups: a no-treatment control group, and 3 treatment groups, using 250, 1,000 or 2,000 international units (U) of BTX-B injections in the hand with more severe symptoms. Four weeks after injection, pain/numbness visual analogue scale scores and Raynaud's score in the groups treated with 1,000 and 2,000 U BTX-B were significantly lower than in the control group and the group treated with 250 U BTX-B. These beneficial effects were sustained until 16 weeks after the single injection. At 4 weeks after injection skin temperature recovery in the group treated with 2,000 U BTX-B was significantly improved. The numbers of digital ulcers in the groups treated with 1,000 and 2,000 U BTX-B were significantly lower than in the control group. In conclusion, 1,000 and 2,000 U BTX-B injections significantly suppressed the activity of Raynaud's phenomenon and digital ulcers in patients with SSc without serious adverse events.

    To report a paradoxical reaction of Raynaud phenomenon following the repeated administration of iloprost in a patient with diffuse cutaneous systemic sclerosis with vascular involvement. In January 2006, a 40-year-old male was diagnosed with diffuse cutaneous systemic sclerosis with pulmonary, esophageal, cutaneous, and vascular involvement (Raynaud phenomenon, with digital ulcers on his hands). In December 2008, treatment with iloprost was started due to worsening disease. Nine cycles of iloprost were administered at a rate of 0.5-1 ng/kg/min (6 hours per day, for 5 days every 6-8 weeks); the patient tolerated this treatment well. However, on the fourth day of cycles 10 and 11, the patient developed paradoxical Raynaud phenomenon in the hand with perfusion when the infusion was increased to 1 ng/kg/min, requiring treatment to be stopped. Treatment was continued during cycles 12 and 13 at 0.5 ng/kg/min; the patient tolerated the treatment well, although paradoxical Raynaud phenomenon occurred when the rate of infusion was increased. Raynaud phenomenon is extremely common in patients with scleroderma, and often is severe. Iloprost has vasodilating, antiplatelet, cytoprotective, and immunomodulating properties, and has been found to be an efficacious alternative to nifedipine for the treatment of Raynaud phenomenon in patients with scleroderma. The Naranjo probability scale indicated that iloprost was the probable cause of the paradoxical Raynaud phenomenon in this patient. This case demonstrates a probable relationship between the rate of infusion of iloprost and the paradoxical reaction of Raynaud phenomenon.

  11. Wound healing after hand surgery in patients with systemic sclerosis--a retrospective analysis of 41 operations in 19 patients.

    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.

    We report the expression of a cDNA clone encoding 695 carboxyl-terminal amino acids of human DNA topoisomerase I (topoI) in Escherichia coli. More than 96% of the anti-HeLa topoI-positive sera from patients with a connective tissue disease displayed also an immunoreactivity with this recombinant protein (the HTopoA protein). Sera from patients with a definite diagnosis systemic sclerosis and reacting with HeLa topoI, all reacted with the HTopoA protein as well. Sera from patients with systemic sclerosis that did not contain anti-topoI antibodies (about 30% of the systemic sclerosis sera), as concluded from HeLa immunoblot, displayed also no immunoreactivity with our recombinant antigen. By expressing different fragments of HTopoA, we were able to assign at least three different autoimmune epitope regions on the HTopoA protein and we show that over a period of 5 years the amount of anti-topoI antibodies against these regions may fluctuate.

    The increasing therapeutic options for relapsing-remitting multiple sclerosis require a specific treatment and risk management to recognize the individual response as well as potential side effects. To switch from pure MS documentation to MS management by implementing a new multiple sclerosis management and documentation tool may be of importance. This article presents the novel computer-based patient management system "multiple sclerosis management system 3D" (MSDS 3D). MSDS 3D allows documentation and visualization of visit schedules and mandatory examinations via defined study modules by integration of data input from patients, attending physicians and MS nurses. It provides forms for the documentation of patient visits as well as clinical and diagnostic findings. Information is collected via interactive touch screens. A specific module which is part of MSDS 3D's current version allows the monthly monitoring of patients under treatment with natalizumab. A checklist covering clinical signs of progressive multifocal leukoencephalopathy (PML) and a detailed questionnaire about the handling of natalizumab in practice have additionally been added. The MS patient management system MSDS 3D has successfully been implemented and is currently being evaluated in a multi-centre setting. Advanced assessment of patient data may allow improvements in clinical practice and research work. The addition of a checklist and a questionnaire into the natalizumab module may support the recognition of PML during its early, treatable course.

    Objective: To evaluate metabolite concentration in the masseter of patients with systemic sclerosis, by analyzing creatine, choline, lipid and lactate levels, and correlating them with the presence of mandibular osteolysis. Materials and methods: The sample included 25 individuals, 15 of them with diagnosis of systemic sclerosis, divided into two groups according to the presence (group I) or absence (group II) of osteolysis, and 10 healthy individuals (group III, control). All of them were submitted to proton magnetic resonance spectroscopy with PRESS sequence and 3D acquisition. Results: Metabolite analysis showed that the creatine and lipid levels were the same for the three groups. Patients in group I presented higher levels of choline when compared with group III. On the other hand, lower lactate levels were observed in groups I and II when compared with the healthy individuals. Creatine/lipid and choline/lactate ratios were the same in the three groups. Conclusion: Lower lactate levels were observed in the patients with systemic sclerosis (groups I and II). Choline levels were increased in the patients with mandibular osteolysis (group I). Creatine/choline, lipid/lactate and choline/lipid ratios were different among the three groups. Further studies are necessary to understand the role played by the masseter in the development of mandibular osteolysis. (author)

    To assess symptoms related to autonomic nervous system alteration in a population of patients suffering from multiple sclerosis (MS) and presenting with urinary symptoms. We investigated 65 patients (mean age 47.5 years) suffering from MS, and presenting with urological dysfunction by means of symptom scores, urodynamic investigation, cardiovascular autonomic function tests (orthostatic hypotension testing, Valsalva test, deep breath test, cold pressor test) and sympathetic skin responses. Forty-five (69%) patients suffered from overactive bladder, 48 (73%) from voiding dysfunction, 14 (21%) from urinary retention and 13 (20%) from fecal incontinence. Urodynamic investigation demonstrated overactive detrusor in 46 (70%) cases, and underactive detrusor in four (6%) cases. Twenty-five (38%) patients had dysautonomia without correlation neither with clinical or urodynamic data, nor gravity of multiple sclerosis (EDSS). In this series, the prevalence of dysautonomia was high in patients suffering from MS and presenting with urinary disorders. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Autologous adipose tissue injection is used in plastic surgery for correction of localized tissue atrophy and has also been successfully offered for treatment of localized scleroderma. We aimed to evaluate whether patients with systemic sclerosis (SSc) and facial handicap could also benefit from this therapy. We included 14 patients (mean age of 53.8 ± 9.6 years) suffering from SSc with facial handicap defined by Mouth Handicap in Systemic Sclerosis Scale (MHISS) score more than or equal to 20, a Rodnan skin score on the face more than or equal to 1, and maximal mouth opening of less than 55 mm. Autologous adipose tissue injection was performed under local anesthesia using the technique of subcutaneous microinjection. The main objective of this study was an improvement of the MHISS score 6 months after the surgical treatment. The procedure was well tolerated. We observed a mean decrease in the MHISS score of 10.7 points (±5.1; P handicap, skin sclerosis, mouth opening limitation, sicca syndrome, and facial pain. Thus, this minimally invasive approach offers a new hope for face therapy for patients with SSc.

    Multiple sclerosis is a demyelinating disease of the central nervous system which only affects humans. This makes it difficult to study at a molecular level, and to develop and test potential therapies that may change the course of the disease. The development of therapies to promote remyelination in multiple sclerosis is a key research aim, to both aid restoration of electrical impulse conduction in nerves and provide neuroprotection, reducing disability in patients. Testing a remyelination therapy in the many and various in vivo models of multiple sclerosis is expensive in terms of time, animals and money. We report the development and characterisation of an ex vivo slice culture system using mouse brain and spinal cord, allowing investigation of myelination, demyelination and remyelination, which can be used as an initial reliable screen to select the most promising remyelination strategies. We have automated the quantification of myelin to provide a high content and moderately-high-throughput screen for testing therapies for remyelination both by endogenous and exogenous means and as an invaluable way of studying the biology of remyelination.

    Several chronic inflammatory disorders, such as rheumatoid arthritis and systemic lupus erythematosus, have been shown to increase coronary artery disease (CAD) risk but the data on systemic sclerosis (SSc) is unclear. We conducted a systematic review and meta-analysis of observational studies that reported odds ratio, relative risk, hazard ratio, or standardized incidence ratio comparing CAD risk in patients with SSc versus non-SSc participants. Pooled risk ratio and 95 % confidence intervals were calculated using a random effect, generic inverse variance method. Four studies were identified and included in our data analysis. The pooled risk ratio of CAD in patients with SSc was 1.82 (95 % CI, 1.40 to 2.36). The statistical heterogeneity of this meta-analysis was moderate with an I (2) of 73 %. Our study demonstrated a statistically significant increased CAD risk among patients with SSc.

    It has been demonstrated that the endocannabinoid system is up-regulated in pathologic fibrosis and that modulation of the cannabinoid receptors might limit the progression of uncontrolled fibrogenesis. The aim of this study was to investigate whether the synthetic cannabinoid receptor agonist WIN55,212-2 could modulate fibrogenesis in an in vitro model of dcSSc. The expression of cannabinoid receptors CB1 and CB2 was assessed in dcSSc fibroblasts and healthy control fibroblasts. To investigate the effect of WIN55,212-2 on dcSSc fibrogenesis, we studied type I collagen, profibrotic cytokines, fibroblast transdifferentiation into myofibroblasts, apoptotic processes and activation of the extracellular signal-related kinase 1/2 pathway prior to and after the treatment with the synthetic cannabinoid at increasing concentrations. Both CB1 and CB2 receptors were over-expressed in dcSSc fibroblasts compared with healthy controls. WIN55,212-2 caused a reduction in extracellular matrix deposition and counteracted several behavioural abnormalities of scleroderma fibroblasts including transdifferentiation into myofibroblasts and resistance to apoptosis. The anti-fibrogenic effect of WIN55,212-2 was not reverted by selective cannabinoid antagonists. Our preliminary findings suggest that cannabinoids are provided with an anti-fibrotic activity, thereby possibly representing a new class of agents targeting fibrosis diseases.

  1. Algorithm for the Diagnosis of Scleroderma. Early Systemic Sclerosis: Definitions and diagnostic criteria

    Full Text Available Introduction: The term scleroderma derives from the Greek words skleros, which means hard, and derma, which means skin. It refers to an acquired systemic inflammatory disease of the connective tissue –also known as systemic sclerosis (SSc– characterized by excessive collagen deposition in the skin and the internal organs that results in fibrosis. The typical vascular lesion in SSc leads to narrowing of the vessel lumen, intimal thickening, medial hypotrophy, and adventitial fibrosis of small muscular vessels, collagen deposition in the other matrix components of interstice, and the Raynaud phenomenon secondary to these widespread microvascular abnormalities. All these characteristics lead to a connective tissue re-modeling. Discussion: Several clinical studies utilize the American Rheumatology Association’s 1980 classification. However, these diagnostic criteria are unsatisfactory because they fail to take into consideration part of the disease spectrum. Early-phase SSc is characterized by the Raynaud phenomenon (in 90% of all patients, sclerodactyly, and positivity for SSc-specific autoantibodies (antinuclear antibodies, anti-topoisomerase I antibodies, anti-RNA polymerase I and III antibodies, anti-centromere antibodies, anti-fibrillarin antibodies, anti-PM-SCL antibodies.. It is necessary to reduce delays in the diagnosis of SSc. Conclusions: Patients with red-flag positivity (Raynaud phenomenon and digital edema require Phase I SSc screening, which consists in capillaroscopic assessment of possible microvascular abnormalities. The work-up will then focus on inflammatory indices, renal function tests, and internal organ involvement (echocardiography, high-resolution computed tomography of the chest, diffusing capacity of the lungs for carbon monoxide.

    White matter hyper intensities (WMHI) on MRI are not rare in patients with progressive systemic sclerosis (PSS). In this presentation, WMHI were developed in both middle cerebellar peduncles and temporal white matter in a patient with PSS, and regressed after medication of high dose steroid. However, new lesions were developed in the subcortices of both precentral gyri, and progressed rapidly to tumefactive hyperintensity on MRI. We report an unusual relapsing and progressive tumefactive demyelinating form of central nervous system involvement in PSS.

    Systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are two archetypal systemic autoimmune diseases which have been shown to share multiple genetic susceptibility loci. In order to gain insight into the genetic basis of these diseases, we performed a pan-meta-analysis of two genome-wide association studies (GWASs) together with a replication stage including additional SSc and SLE cohorts. This increased the sample size to a total of 21 109 (6835 cases and 14 274 controls). We selected for replication 19 SNPs from the GWAS data. We were able to validate KIAA0319L (P = 3.31 × 10−11, OR = 1.49) as novel susceptibility loci for SSc and SLE. Furthermore, we also determined that the previously described SLE susceptibility loci PXK (P = 3.27 × 10−11, OR = 1.20) and JAZF1 (P = 1.11 × 10−8, OR = 1.13) are shared with SSc. Supporting these new discoveries, we observed that KIAA0319L was overexpressed in peripheral blood cells of SSc and SLE patients compared with healthy controls. With these, we add three (KIAA0319L, PXK and JAZF1) and one (KIAA0319L) new susceptibility loci for SSc and SLE, respectively, increasing significantly the knowledge of the genetic basis of autoimmunity.

  6. Familial autoimmunity and polyautoimmunity in 60 Brazilian Midwest patients with systemic sclerosis

    Directory of Open Access Journals (Sweden)

    Alex Magno Coelho Horimoto

    Full Text Available ABSTRACT Introduction: Systemic sclerosis (SSc is a connective tissue disease of unknown etiology, characterized by a triad of vascular injury, autoimmunity and tissue fibrosis. It is known that a positive family history is the greatest risk factor already identified for the development of SSc in a given individual. Preliminary observation of a high prevalence of polyautoimmunity and of familial autoimmunity in SSc patients support the idea that different autoimmune phenotypes may share common susceptibility variants. Objectives: To describe the frequency of familial autoimmunity and polyautoimmunity in 60 SSc patients in the Midwest region of Brazil, as well as to report the main autoimmune diseases observed in this association of comorbidities. Methods: A cross-sectional study with recruitment of 60 consecutive patients selected at the Rheumatology Department, University Hospital, Medicine School, Federal University of Mato Grosso do Sul (FMUFMS, as well as interviews of their relatives during the period from February 2013 to March 2014. Results: A frequency of 43.3% of polyautoimmunity and of 51.7% of familial autoimmunity in SSc patients was found. Patients with the presence of polyautoimmunity and familial autoimmunity presented primarily the diffuse form of SSc, but this indicator did not reach statistical significance. The autoimmune diseases most frequently observed in polyautoimmunity patients were: Hashimoto's thyroiditis (53.8%, Sjögren's syndrome (38.5%, and inflammatory myopathy (11.5%. The main autoimmune diseases observed in SSc patients' relatives were: Hashimoto's thyroiditis (32.3%, rheumatoid arthritis (22.6%, and SLE (22.6%. The presence of more than one autoimmune disease in SSc patients did not correlate with disease severity or activity. Conclusions: From the high prevalence of coexisting autoimmune diseases found in SSc patients, we stress the importance of the concept of shared autoimmunity, in order to promote a

    Systemic sclerosis (SSc) is a heterogeneous chronic autoimmune disease that it is extremely difficult to diagnose in the early phase, resulting in a critical delay in therapy which is often begun when internal organ involvement is already irreversible. The ACR or LeRoy criteria have a low sensitivity for the early phases; these criteria were replaced by the ACR/EULAR 2013 criteria which improved the disease classification. Therefore, the SSc diagnosis may be delayed for several years after the onset of Raynaud's phenomenon (RP) and even after the onset of the first non-RP symptom. RP, antinuclear antibodies (ANA) positivity, and puffy fingers were recently indicated as "red flags" (by the VEDOSS project)--that is, the main elements for suspicion of SSc in the very early phase of the disease. Confirming the diagnosis requires further tests, particularly nailfold videocapillaroscopy and evaluation of specific disease antibodies (anti-centromere and anti-topoisomerase I). In this way, the VEDOSS project identified patients in the very early phase of disease enabling a "window of opportunity" whereby the physician can act with effective drugs to block or at least slow the progression of the disease. The principal challenge in the fight against SSc is to detect valid predictors of disease evolution in order to treat patients in the early stage of disease. While waiting to find valid predictors, a close follow-up of the patients with the VEDOSS red flags is essential, as is a close collaboration between rheumatologists and general practitioners in order to identify all potential SSc patients as soon as possible.

    The objective of this study is to test the association of the severity of nailfold capillaroscopy (NFC) abnormalities with mortality in systemic sclerosis (SSc). One hundred and seventy SSc patients underwent an extensive evaluation (including high-resolution computed tomography, pulmonary function tests, and Doppler echocardiography) at baseline following a standard protocol. Capillary loss on NFC was evaluated using the avascular score (AS, ranging from 0 to 3), and the mean number of ectasias, megacapillaries, and hemorrhages per finger was also recorded. After a mean period of 10.1 ± 4.9 years, the life status of the patients was ascertained. Univariate and multivariate Cox proportional hazards models were used for statistical analysis. Overall, 73 patients died. By univariate Cox analysis, the AS was significantly associated with mortality (hazard ratio [HR] = 1.64, 95% CI 1.22 to 2.19, p = 0.001). In our study, this association was stronger than that of race, gender, anticentromere antibodies, anti-topoisomerase I antibodies, and form of disease and had similar strength to that of skin score in univariate analyses. However, after controlling for a combination of variables (age, skin score, gender, race, signs of peripheral ischemia, and extent of interstitial lung disease, all independently associated with mortality), the association of AS with mortality was blunted (HR = 1.15, 95% CI 0.80 to 1.65, p = 0.445). Other NFC variables were not related to mortality. AS was associated with higher risk of death and, despite not having an independent association with mortality after controlling for a set of demographic and clinical variables, may be a useful tool in prognostic evaluation of SSc.

    The term scleroderma pattern typically defines capillary abnormalities of scleroderma spectrum disorders, mainly systemic sclerosis (SSc) and dermatomyositis (DM). Our study aimed to investigate differences in nailfold videocapillaroscopy (NVC) between DM and SSc, with a cross-sectional and longitudinal evaluation. NVC features of 29 consecutive patients with DM were compared with 90 patients with SSc categorized into the 3 subsets of scleroderma pattern: early, active, and late. Twenty patients with DM and all with SSc were also longitudinally reevaluated after 30 months of followup. At baseline, all SSc groups showed giant capillaries, with significant differences with DM only for early and active pattern. Ramified capillaries were significantly more frequent and severe in DM than in early and active patterns, while DM showed an opposite trend compared with late pattern. Capillary loss was lower in early pattern and higher in active and late, compared with DM. Finally, giant-ramified capillaries were almost exclusive of DM. During followup, NVC showed a different evolution in DM and SSc. In DM we recorded a reduction of giant capillaries, while ramified capillaries increased both in DM and in early and active SSc pattern. The number of capillaries recovered in DM; conversely, capillary loss slightly worsened in all SSc patterns. Giant-ramified capillaries significantly decreased in patients with DM, remaining rare in patients with SSc. Our study strengthens the specificity of DM and SSc microangiopathy and points out the need for large prospective studies to confirm our results and possibly to revise current terminology by distinguishing between "scleroderma" and "dermatomyositis" patterns.

    Treatment for gastrointestinal tract (GIT) disease in systemic sclerosis (SSc) is challenging as no immunosuppressive or anti-fibrotic therapy is available with clearly proven efficacy. Probiotics are viable, non-pathogenic microorganisms that are hypothesized to improve the composition of the intestinal microbiota from a potentially harmful composition to a composition that is beneficial to the host. Our hypothesis is that GIT symptoms in SSc patients with moderate bloating would improve with probiotic implementation. Ten patients with a moderate-to-severe distention/bloating score (1.25-3.00) on the University of California Los Angeles Scleroderma Clinical Trials Consortium Gastrointestinal Tract 2.0 (UCLA SCTC GIT 2.0), but otherwise stable organ disease not requiring any medication adjustment were recruited from the University of Utah Scleroderma Center. We compared the GIT 2.0 scores at baseline and after 2 months of use of Align (bifidobacterium infantis; 109 CFU per capsule) or Culturelle (lactobacillus GG; 109 CFU per capsule) using paired t-test and calculated effect size (ES). Significant improvement in total GIT 2.0 score (ES = 0.82), reflux (ES = 0.33), bloating/distention (ES = 1.76), and emotional scales (ES = 0.18) were reported after two months of daily probiotic use. This pilot study suggests probiotics significantly improve the reflux, distention/ bloating, and total GIT scales in SSc patients. As hypothesized, the largest effect was seen in distention/bloating scale. Probiotics may be useful for treatment of SSc-associated distention/ bloating.

    Full Text Available Scoring systems have been developed to interpret the disease severity objectively by evaluating the parameters of the disease. Body surface area, visual analogue scale, and physician global assessment are the most frequently used scoring systems for evaluating the clinical severity of the dermatological diseases. Apart from these scoring systems, many specific scoring systems for many dermatological diseases, including acne (acne vulgaris, acne scars, alopecia (androgenetic alopecia, tractional alopecia, bullous diseases (autoimmune bullous diseases, toxic epidermal necrolysis, dermatitis (atopic dermatitis, contact dermatitis, dyshidrotic eczema, hidradenitis suppurativa, hirsutismus, connective tissue diseases (dermatomyositis, skin involvement of systemic lupus erythematosus (LE, discoid LE, scleroderma, lichen planoplaris, mastocytosis, melanocytic lesions, melasma, onychomycosis, oral lichen planus, pityriasis rosea, psoriasis (psoriasis vulgaris, psoriatic arthritis, nail psoriasis, sarcoidosis, urticaria, and vitiligo, have also been developed. Disease severity scoring methods are ever more extensively used in the field of dermatology for clinical practice to form an opinion about the prognosis by determining the disease severity; to decide on the most suitable treatment modality for the patient; to evaluate the efficacy of the applied medication; and to compare the efficiency of different treatment methods in clinical studies.

    Quantitative assessment of macular and nerve fibre layer thickness in multiple sclerosis patients with regard to expanded disability status scale (EDSS) and presence or absence of previous optic neuritis episodes. We recruited 62 patients with multiple sclerosis (53 relapsing-remitting and 9 secondary progressive) and 12 disease-free controls. All patients underwent an ophthalmological examination, including quantitative analysis of the nerve fibre layer and macular thickness using optical coherence tomography. Patients were classified according to EDSS as A (lower than 1.5), B (between 1.5 and 3.5), and C (above 3.5). Mean nerve fibre layer thickness in control, A, B, and C groups was 103.35±12.62, 99.04±14.35, 93.59±15.41, and 87.36±18.75μm respectively, with statistically significant differences (Pmultiple sclerosis patients is related to the EDSS level. Patients with previous optic neuritis episodes have a thinner retinal nerve fibre layer than patients with no history of these episodes. Mean macular thickness is not correlated to EDSS level.

    2016-07-01

    Full Text Available Background: Systemic sclerosis (SSc is an autoimmune rheumatic connective tissue disease. In normal wound healing process, fibroblasts are activated, proliferated and involved in tissue repair, and then removed by apoptosis. In systemic sclerosis, patient’s fibrosis occurs when fibroblasts become resistant to apoptosis and secrete a large amount of collagen and other extracellular matrixes. As the primary causes the disease are very complex and often unknown, it is necessary to consider or target the secondary causes of disease, such as the unresponsiveness of activated fibroblasts to apoptosis as the major factor in the creation and deployment of illness. In this study, we examined the expression levels of two key pro-apoptotic genes, Fas and Apaf-1, which are respectively involved in external and internal pathway of apoptosis. Methods: In a case-control study skin biopsy samples were obtained from 19 patients with diffuse SSc, and 16 healthy controls. Dermal fibroblasts were cultured and total RNA was isolated from cell populations using High Pure RNA Isolation Kit (Roche Applied Science, Mannheim, Germany, followed by cDNA synthesis using RevertAid First Strand cDNA Synthesis Kit (Thermo Fisher Scientific Inc., Massachusetts, USA. Real-time PCR was performed using SYBRGreen gene expression master mix (Takara Shuzo, Co., Ltd, Shiga, Japan and specific primers for Fas and Apaf-1. Real-time data were analyzed using the (2-ΔCT×1000 method. Statistical analysis was accomplished by using the SPSS software, v22 (IBM, Armonk, NY, USA. The P value less than 0.05 were recognized as a significant threshold. All data are represented as the mean ± SEM. Results: Our results showed no significant difference in Fas (P=0.8 and Apaf-1 (P=0.17 mRNA expression levels between skin fibroblasts of systemic sclerosis patients and healthy controls. Conclusion: In this study we observed no significant change in Apaf-1 and Fas mRNA levels in systemic sclerosis

    Bilateral vocal fold immobility (BVFI) can be the result of a primary disorder or as an iatrogenic complication of surgery or intubation. Laryngeal involvement can be a rare complication of connective tissue disorders and it usually occurs in association with other symptoms and signs that indicate active disease. We present a case of BVFI in a patient with an overlap syndrome rheumatoid arthritis/systemic sclerosis, referred to our division because of dysphonia and dyspnea. The video-laryngostroboscopy showed the presence of BVFI. Physical examination, blood tests, lung and neck high resolution computed tomography scans did not demonstrate significant abnormalities. She was treated with pulses of intravenous methylprednisolone with slow improvement.

    Full Text Available Introduction: Multiple sclerosis (MS is a chronic, progressive, demyelinating disease of the central nervous system. 2.5 million people are affected by MS worldwide; in Poland, the number of patients is approximately 40,000. Patients with multiple sclerosis suffer from a number of symptoms associated with this disease. Aim of the research: To assess the effectiveness of physiotherapy in MS. Material and methods : The study enrolled 25 MS patients aged 27–72 years (including 16 females and 9 males, undergoing 6-week rehabilitation. They were examined twice: before and after rehabilitation. The study used two questionnaires created by the author. Evaluation of the clinical status and disease severity was based on the Kurtzke Expanded Disability Status Scales (EDSS, the Lawton Instrumental Activities of Daily Living (IADL Scale, and the Multiple Sclerosis Impact Scale (MSIS-29. The results were analysed with Student’s t-test and the chi-square (χ 2 test. Results : Statistical analysis showed significant (the level of significance was 0.05 progress in the functional status of the patients after physiotherapy, as evidenced by improved results with respect to the motor efficiency in the Kurtzke Expanded Disability Status Scale (EDSS, the functional assessment in the Lawton Instrumental Activities of Daily Living (IADL Scale, and the influence of MS on patients’ daily life in the Multiple Sclerosis Impact Scale (MSIS-29 seen in the majority of the patients, which confirms a positive impact of the therapy. Conclusions: In the study group, comprehensive rehabilitation had a beneficial influence on the improvement of functional status and the level of motor ability. Physiotherapy turned out to be an extremely effective form of symptomatic treatment of MS patients.

    Full Text Available OBJECTIVE: The aim of our study was to elucidate the pathophysiology of systemic sclerosis-related osteoporosis and the prevalence of vertebral fragility fracture in postmenopausal women with systemic sclerosis (SSc. METHODOLOGY: Fifty-four postmenopausal women with scleroderma and 54 postmenopausal controls matched for age, BMI, and smoking habits were studied. BMD was measured by dual energy-x-ray absorptiometry at spine and femur, and by ultrasonography at calcaneus The markers of bone turnover included serum osteocalcin and urinary deoxypyridinoline. All subjects had a spine X-ray to ascertain the presence of vertebral fractures. RESULTS: bone mineral density at lumbar spine (BMD 0.78±0.08 vs 0.88±0.07; p<0,001, femoral neck (BMD: 0.56±0.04 vs 0.72±0.07; p<0,001 and total femur (BMD: 0.57±0.04 vs 0.71±0.06; p<0,001 and ultrasound parameter at calcaneus (SI: 80.10±5.10 vs 94.80±6.10 p<0,001 were significantly lower in scleroderma compared with controls; bone turnover markers and parathyroid hormone level were significantly higher in scleroderma compared with controls, while serum of 25(OHD3 was significantly lower. In scleroderma group the serum levels of 25(OHD3 significantly correlated with PTH levels, BMD, stiffness index and bone turnover markers. One or more moderate or severe vertebral fractures were found in 13 patients with scleroderma, wherease in control group only one patient had a mild vertebral fracture. CONCLUSION: Our data shows, for the first time, that vertebral fractures are frequent in subjects with scleroderma, and suggest that lower levels of 25(OHD3 may play a role in the risk of osteoporosis and vertebral fractures.

    2013-09-01

    Full Text Available The current diagnostic criteria for multiple sclerosis (MS confirm the relevant role of magnetic resonance imaging (MRI, supporting the possibility of characterizing the dissemination in space (DIS and the dissemination in time (DIT in a single scan. To maintain the specificity of these criteria, it is necessary to determine whether T2/FLAIR visible lesions and the gadolinium enhancement can be attributed to diseases that mimic MS. Several diseases are included in the MS differential diagnosis list, including diseases with exacerbation, remitting periods and numerous treatable infectious diseases, which can mimic the MRI features of MS. We discuss the most relevant imaging features in several infectious diseases that resemble MS and examine the primary spatial distributions of lesions and the gadolinium enhancement patterns related to MS. Recognizing imaging "red flags" can be useful for the proper diagnostic evaluation of suspected cases of MS, facilitating the correct differential diagnosis by assessing the combined clinical, laboratory and MR imaging information.

    Objective S-Nitrosothiols (RSNOs) are bioactive forms of nitric oxide which are involved in cell signalling and redox regulation of vascular function. Circulating S-nitrosothiols are predominantly in the form of S-nitrosoalbumin. In this study plasma concentrations of S-nitrosothiols were measured in patients with systemic sclerosis (SSc) where NO metabolism is known to be abnormal. Patients and methods Venous blood was collected from 16 patients with Raynaud's phenomenon (RP), 45 with systemic sclerosis (SSc) (34 patients had limited SSc (IcSSc) and 11 diffuse cutaneous disease (dcSSc)). Twenty six healthy subjects were used as controls. Plasma S-nitrosothiol concentrations were measured by chemiluminescence. The measurements were related to the extent of biological age, capillary/skin scores and disease duration. Results Plasma RSNO levels in patients with Raynaud's phenomenon (RP) and in those with SSc was significantly lower compared to the concentrations in control subjects. In SSc, plasma S-nitrosothiols were often below the level of detection (1nM). Conclusions Low S-nitrosothiol concentrations were observed in the blood of patients with SSc and patients with RP indicating a profound disturbance of nitric oxide metabolism. PMID:25446164

    Objective. Treatment of scleroderma is challenging and limited. The aim of our study was to evaluate the usefulness of thermography in assessment of the clinical condition (joints movability and skin thickness) in clinically advanced patients with systemic sclerosis before and after ozone therapy. Method. The study included 42 patients aged 32 to 73 years with advanced systemic sclerosis hospitalized in the university clinic between 2003 and 2006. Thermography and clinical examinations were conducted at baseline and after two series of bath in water with ozone. Results. The comparison of results showed significant increase in skin temperature by 2.5°C, significant increase in interphalangeal joints movability by 18 degrees, and significant decrease in skin score by 14.7 points. The skin temperature was correlated with skin score ( r = -0.59) and joints movability ( r = +0.8). Conclusions. Ozone therapy shows positive effect on clinical parameters and skin temperature as measured with thermography. The study indicated possibility of introducing ozonotherapy as an independent therapy in cases with low level of progression or during remission periods and as additional treatment in patients with advanced disease requiring immunosuppressive treatment. Thermography is useful in assessment of skin condition showing strong correlation between skin temperature and clinical parameters.

    The long disease duration of multiple sclerosis and the increasing therapeutic options require a individualized therapeutic approach which should be carefully documented over years of observation. To switch from MS documentation to an innovative MS management, new computer- and internet-based tools could be implemented as we could demonstrate with the novel computer-based patient management system "multiple sclerosis management system 3D" (MSDS 3D). MSDS 3D allows documentation and management of visit schedules and mandatory examinations via defined study modules by integration of data input from various sources (patients, attending physicians and MS nurses). It provides forms for the documentation of patient visits as well as clinical and diagnostic findings. Information can be collected via interactive touch screens. Specific modules allow the management of highly efficacious treatments as natalizumab or fingolimod. MSDS can be used to transfer the documented data to databases as, e.g. the registry of the German MS society or REGIMS. MSDS has already been implemented successfully in clinical practice and is currently being evaluated in a multicenter setting. High-quality management and documentation are crucial for improvements in clinical practice and research work.

    To investigate cardiopulmonary function in progressive systemic sclerosis with diffuse scleroderma, we studied 26 patients with maximal exercise and redistribution thallium scans, rest and exercise radionuclide ventriculography, pulmonary-function testing, and chest roentgenography. Although only 6 patients had clinical evidence of cardiac involvement, 20 had abnormal thallium scans, including 10 with reversible exercise-induced defects and 18 with fixed defects (8 had both). Seven of the 10 patients who had exercise-induced defects and underwent cardiac catheterization had normal coronary angiograms. Mean resting left ventricular ejection fraction and mean resting right ventricular ejection fraction were lower in patients with post-exercise left ventricular thallium defect scores above the median (59 +/- 13 per cent vs. 69 +/- 6 per cent, and 36 +/- 12 per cent vs. 47 +/- 7 per cent, respectively). The authors conclude that in progressive systemic sclerosis with diffuse scleroderma, abnormalities of myocardial perfusion are common and appear to be due to a disturbance of the myocardial microcirculation. Both right and left ventricular dysfunction appear to be related to this circulatory disturbance, suggesting ischemically mediated injury

  5. Multiple sclerosis and herpesvirus interaction

    2013-09-01

    Full Text Available Multiple sclerosis is the most common autoimmune inflammatory demyelinating disease of the central nervous system, and its etiology is believed to have both genetic and environmental components. Several viruses have already been implicated as triggers and there are several studies that implicate members of the Herpesviridae family in the pathogenesis of MS. The most important characteristic of these viruses is that they have periods of latency and exacerbations within their biological sanctuary, the central nervous system. The Epstein-Barr, cytomegalovirus, human herpesvirus 6 and human herpesvirus 7 viruses are the members that are most studied as being possible triggers of multiple sclerosis. According to evidence in the literature, the herpesvirus family is strongly involved in the pathogenesis of this disease, but it is unlikely that they are the only component responsible for its development. There are probably multiple triggers and more studies are necessary to investigate and define these interactions.

  6. Relationship between Body Mass Composition, Bone Mineral Density, Skin Fibrosis and 25(OH Vitamin D Serum Levels in Systemic Sclerosis.

    Full Text Available A reduced bone mineral density (BMD is observed in several rheumatic autoimmune diseases, including Systemic Sclerosis (SSc; nevertheless, data concerning the possible determinants of bone loss in this disease are not fully investigated. The aim of this study is to evaluate the relationship between BMD, body mass composition, skin sclerosis and serum Vitamin D levels in two subsets of SSc patients. 64 post-menopausal SSc patients, classified as limited cutaneous (lcSSc or diffuse cutaneous (dcSSc SSc, were studied. As control, 35 healthy post-menopausal women were recruited. Clinical parameters were evaluated, including the extent of skin involvement. BMD at lumbar spine, hip, femoral neck and body mass composition were determined by dual-energy X-ray absorptiometry. Serum calcium, phosphorus, alkaline phosphatase, urine pyridinium cross-links, intact parathyroid hormone and 25-hydroxyvitamin D (25OHD were measured. BMD at spine, femoral neck and total hip was significantly lower in SSc patients compared to controls. In dcSSc subset, BMD at spine, femoral neck and total hip was significantly lower compared to lcSSc. No differences in both fat and lean mass were found in the three study groups even if patients with dcSSc showed a slightly lower total body mass compared to healthy controls. Total mineral content was significantly reduced in dSSc compared to both healthy subjects and lcSSc group. Hypovitaminosis D was observed both in healthy post-menopausal women and in SSc patients, but 25OHD levels were significantly lower in dcSSc compared to lcSSc and inversely correlated with the extent of skin thickness. These results support the hypothesis that the extent of skin involvement in SSc patients could be an important factor in determining low circulating levels of 25OHD, which in turn could play a significant role in the reduction of BMD and total mineral content.

    Fatigue is reported as the most common symptom by patients with multiple sclerosis (MS). The physiological and functional parameters related to fatigue in MS patients are currently not well established. A new wearable wireless body measurement system, named Fatigue Monitoring System (FAMOS......), was developed to study fatigue in MS. It can continuously measure electrocardiogram, body-skin temperature, electromyogram and motions of feet. The goal of this study is to test the ability of distinguishing fatigued MS patients from healthy subjects by the use of FAMOS. This paper presents the realization...... of the measurement system including the design of both hardware and dedicated signal processing algorithms. Twenty-six participants including 17 MS patients with fatigue and 9 sex- and age-matched healthy controls were included in the study for continuous 24 h monitoring.

    The results of urinary determinations of E-2 prostaglandines by radioimmunoassay (RIA) in 24-hour urine are presented for three groups: progressive systemic sclerotic patients with normotension and with elevated or normal APR, progressive systemic sclerotic patients with hypertension and with normal or low APR, control group of normal subjects. In a recent report of progressive systemic sclerosis in patients we demonstrated changes in the urine concentratrion of APR levels, sodium excretion and in total blood volume. Based on these findings we felt the need to perform quantifications of E-2 prostaglandines (PGE-2) in 24-hour recently taken urine samples stored at 70 0 and measure the sodium amounts excreted in the urine. We concluded that urinary determination of E-2 prostaglandines was the most suitable for our study as it allowed the establishment of relationships between APR, aldosterone and metabolic sodium balance.

    Glutamate excitotoxicity contributes to oligodendroglial and axonal damage in multiple sclerosis pathology. Extracellular glutamate concentration in the brain is controlled by cystine/glutamate antiporter (system xc-), a membrane antiporter that imports cystine and releases glutamate. Despite this, the system xc - activity and its connection to the inflammatory reaction in multiple sclerosis (MS) is largely unknown. Longitudinal in vivo magnetic resonance (MRI) and positron emission tomography (PET) imaging studies with 2-[ 18 F]Fluoro-2-deoxy-D-glucose ([ 18 F]FDG), [ 11 C]-(R)-1-(2-chlorophenyl)-N-methyl-N-1(1-methylpropyl) -3-isoquinolinecarbox amide ([ 11 C]PK11195) and (4S)-4-(3- 18 F-fluoropropyl)-L-glutamate ([ 18 F]FSPG) were carried out during the course of experimental autoimmune encephalomyelitis (EAE) induction in rats. [ 18 F]FSPG showed a significant increase of system xc - function in the lumbar section of the spinal cord at 14 days post immunization (dpi) that stands in agreement with the neurological symptoms and ventricle edema formation at this time point. Likewise, [ 18 F]FDG did not show significant changes in glucose metabolism throughout central nervous system and [ 11 C]PK11195 evidenced a significant increase of microglial/macrophage activation in spinal cord and cerebellum 2 weeks after EAE induction. Therefore, [ 18 F]FSPG showed a major capacity to discriminate regions of the central nervous system affected by the MS in comparison to [ 18 F]FDG and [ 11 C]PK11195. Additionally, clodronate-treated rats showed a depletion in microglial population and [ 18 F]FSPG PET signal in spinal cord confirming a link between neuroinflammatory reaction and cystine/glutamate antiporter activity in EAE rats.

    Systemic sclerosis (SSc) is a complex disease characterized by immune dysregulation, extensive vascular damage and wide-spread fibrosis. Human leukocyte antigen-G (HLA-G) is a non-classic class I major histocompatibility complex (MHC) molecule characterized by complex immuno-modulating properties. HLA-G is expressed on the membrane of different cell lineages in both physiological and pathological conditions. HLA-G is also detectable in soluble form (sHLA-G) deriving from the shedding of surface isoforms (sHLA-G1) or the secretion of soluble isoforms (HLA-G5). Several immunosuppressive functions have been attributed to both membrane-bound and soluble HLA-G molecules. The plasma levels of sHLA-G were higher in SSc patients (444.27 ± 304.84 U/ml) as compared to controls (16.74 ± 20.58 U/ml) (p G (r: 0.65; p G1 (r: 0.60; p = 0.003) and HLA-G5 (r: 0.47; p = 0.02). The percentage of HLA-G-positive monocytes (0.98 ± 1.72), CD4+ (0.37 ± 0.68), CD8+ (2.05 ± 3.74) and CD4+CD8+ double positive cells (14.53 ± 16.88) was higher in SSc patients than in controls (0.11 ± 0.08, 0.01 ± 0.01, 0.01 ± 0.01 and 0.39 ± 0.40, respectively) (p G molecules and the membrane expression of HLA-G by PBMC is clearly elevated suggesting an involvement of HLA-G molecules in the immune dysregulation of SSc.

    Immune activation is a hallmark of systemic sclerosis (SSc). However, the immunological alterations that occur in preclinical and non-fibrotic SSc and that differentiate these subjects from those with primary Raynaud's phenomenon (PRP) or healthy controls (HC) are poorly defined. We isolated CD56+

    Full Text Available Introduction. Pneumatosis intestinalis (PI is an uncommon pathology characterised by the presence of gas within the intestinal wall. It has been associated with various conditions, including connective tissue diseases. This is the first report of PI being the initial presentation of systemic sclerosis. Case Presentation. The patient, a 75-year-old female, presented with an 8-month history of worsening dysphagia and epigastric pain, as well as other nonspecific symptoms. Initial investigations with an oesophagogastroduodenoscopy diagnosed Candida oesophagitis and also identified an extrinsic compression of the gastric antrum. Subsequently a CT scan of the abdomen and pelvis showed moderately dilated small bowel loops and PI. Due to the patient’s stability, non-critical clinical condition, conservative management was instituted. More detailed investigations confirmed the diagnosis of systemic sclerosis with positive anticentromeric and antinuclear antibodies. The patient improved on methotrexate and was discharged with appropriate outpatient follow-up. Discussion. PI is a rare but well-documented pathology associated with connective tissue diseases, such as systemic sclerosis. In most cases, conservative management is preferable to surgical intervention, depending on the patient’s clinical presentation and progress. This is the first report of PI being the initial presentation of a patient with systemic sclerosis responsive to conservative management.

  20. Modulation of Fibrosis in Systemic Sclerosis by Nitric Oxide and Antioxidants

    Directory of Open Access Journals (Sweden)

    Audrey Dooley

    2012-01-01

    Full Text Available Systemic sclerosis (scleroderma: SSc is a multisystem, connective tissue disease of unknown aetiology characterized by vascular dysfunction, autoimmunity, and enhanced fibroblast activity resulting in fibrosis of the skin, heart, and lungs, and ultimately internal organ failure, and death. One of the most important and early modulators of disease activity is thought to be oxidative stress. Evidence suggests that the free radical nitric oxide (NO, a key mediator of oxidative stress, can profoundly influence the early microvasculopathy, and possibly the ensuing fibrogenic response. Animal models and human studies have also identified dietary antioxidants, such as epigallocatechin-3-gallate (EGCG, to function as a protective system against oxidative stress and fibrosis. Hence, targeting EGCG may prove a possible candidate for therapeutic treatment aimed at reducing both oxidant stress and the fibrotic effects associated with SSc.

    Full Text Available Systemic sclerosis (SSc is a fibrotic autoimmune disease in which the genetic component plays an important role. One of the strongest SSc association signals outside the human leukocyte antigen (HLA region corresponds to interferon (IFN regulatory factor 5 (IRF5, a major regulator of the type I IFN pathway. In this study we aimed to evaluate whether three different haplotypic blocks within this locus, which have been shown to alter the protein function influencing systemic lupus erythematosus (SLE susceptibility, are involved in SSc susceptibility and clinical phenotypes. For that purpose, we genotyped one representative single-nucleotide polymorphism (SNP of each block (rs10488631, rs2004640, and rs4728142 in a total of 3,361 SSc patients and 4,012 unaffected controls of Caucasian origin from Spain, Germany, The Netherlands, Italy and United Kingdom. A meta-analysis of the allele frequencies was performed to analyse the overall effect of these IRF5 genetic variants on SSc. Allelic combination and dependency tests were also carried out.

Our patient with systemic sclerosis presented with a very aggressive form of pulmonary hypertension due to a lethal combination of pulmonary veno-occlusive disease (PVOD and pulmonary arterial thrombosis. This combined presentation has never before been reported in medical literature.Case report: A 75-year-old woman with a 4-month history of atypical chest pains was admitted with a 3-week history of worsening symptoms of shortness of breath, reduced exercise tolerance, and bilateral pitting edema. On examination she had thickened skin in her hands, telangiectasia on her face, maculopapular rash in her legs, raised jugular venous pressure, and bilateral pitting edema. Her autoimmune profile revealed positive anticentromere antibodies, and her echocardiogram showed right ventricular systolic pressure of 91 mmHg. She also had renal impairment secondary to hypoperfusion. A diagnosis of isolated pulmonary hypertension secondary to limited systemic sclerosis was made. As she was clinically improving on slow diuretic infusion and awaiting transfer to a specialist center for management of pulmonary hypertension, our patient died due to cardiopulmonary arrest. Her postmortem revealed that she died of a combination of PVOD and pulmonary arteriopathy due to thrombosis.Conclusion: This is clearly a unique case both in presentation and difficulty of management. Pulmonary vasodilators used in therapy of pulmonary arteriopathy can be detrimental in patients with PVOD. There is no definitive investigation, curative treatment, or management, that exists for a combination of PVOD and pulmonary arteriopathy due to thrombosis secondary to systemic sclerosis.Keywords: pulmonary veno-occlusive disease, pulmonary arterial hypertension, systemic sclerosis, pulmonary arteriopathy with thrombosis

    Therapeutic hypothermia favorably impacts neurologic outcomes in patients after cardiopulmonary arrest, although the appropriate target temperature is less clear. Its safety profile in patients with systemic sclerosis (SSc) and Raynaud phenomenon (RP), who may be at increased risk for ischemic complications, has not been addressed in the literature, to our knowledge. Digital lesions are commonly seen in patients with SSc, and cold-induced myocardial ischemia has also been reported. We describe a case of a man with SSc, RP, and digital ulcers who underwent therapeutic hypothermia after cardiopulmonary arrest. He regained full neurologic function, and except for digital necrosis, no hypothermia-associated adverse events were observed. Other risk factors for ischemia, such as cocaine use, may have contributed to the development of the digital necrosis. However, clinicians should be aware of the risk for ischemic complications in patients with SSc and RP when considering the appropriate target temperature after cardiopulmonary arrest.

    Full Text Available Systemic sclerosis (SSc is a multisystem fibrotic and autoimmune disease. Both genetic and epigenetic elements mediate SSc pathophysiology. This review summarizes the role of one epigenetic element, known as microRNAs (miRNAs, involved in different signaling pathways of SSc pathogenesis. The expression of key components in transforming growth factor-β (TGF-β signaling pathway has been found to be regulated by miRNAs both upstream and downstream of TGF-β. We are specifically interested in the pathway components upstream of TGF-β, while miRNAs in other signaling pathways have not been extensively studied. The emerging role of miRNAs in vasculopathy of SSc suggests a promising new direction for future investigation. Elucidation of the regulatory role of miRNAs in the expression of signaling factors may facilitate the discovery of novel biomarkers in SSc and improve the understanding and treatment of this disease.

    For many years, multiple sclerosis (MS) patients have been self-medicating with illegal street cannabis to alleviate symptoms associated with MS. Data from animal models of MS and clinical studies have supported the anecdotal data that cannabis can improve symptoms such as limb spasticity, which are commonly associated with progressive MS, by the modulation of excessive neuronal signalling. This has lead to cannabis-based medicines being approved for the treatment of pain and spasticity in MS for the first time. Experimental studies into the biology of the endocannabinoid system have revealed that cannabinoids have activity, not only in symptom relief but also potentially in neuroprotective strategies which may slow disease progression and thus delay the onset of symptoms such as spasticity. This review appraises the current knowledge of cannabinoid biology particularly as it pertains to MS and outlines potential future therapeutic strategies for the treatment of disease progression in MS.

    In this paper an immunodominant epitope of Topoisomerase I is described. An epitope expression sublibrary was constructed from Topoisomerase I cDNA. The subclones were screened with an antiserum from a patient with systemic sclerosis (SSc). The positive clones defined one immunodominant B cell epitope (epitope III), which was located at the carboxyterminal part of the protein. The epitope, 52 amino acids in length, neither contains the p30gag sequence nor the suggested active site Tyr-723, both presumed antibody recognition sites. More than 70% of our anti-TopoI sera recognize this epitope III, indicating that it is a major recognition site of the anti-TopoI autoantibodies in SSc sera. DNA relaxation experiments show that all sera that recognize epitope III and most sera with antibodies to other epitopes inhibit Topoisomerase I activity.

    Full Text Available Objective: to estimate heart rate variability (HRV in patients with systemic sclerosis (SS and to investigate their relationship to echocardiographic structural and functional changes in the heart.Subjects and methods. The investigation enrolled 125 patients with SS and 50 gender- and age-matched apparently healthy individuals who made up a control group. In addition to clinical examinations, 73 patients underwent HRV assessment from 24-hour Holter electrocardiogram (ECG monitoring results and 121 patients had echocardiography (EchoCG. 24-hour Holter ECG monitoring was carried out in all control individuals.Results and discussion. Examination of the main parameters of time-domain HRV in patients with SS revealed a significant decline in all temporal and spectral indices, except for the mean R–R interval duration (meanNN, as compared with the control group. EchoCG detected a variety of changes, primarily the induration and calcification of aortic and mitral valves in most patients. Left ventricular diastolic dysfunction was encountered in almost half of the patients with SS. Eight patients had a lower left ventricular ejection fraction (LVEF, which was <55%. Studying the association of HRV values with separate EchoCG parameters revealed significant inverse correlations of the mean standard deviation of R–R intervals in 5-minute recording segments during 24 hours with the thickness of the interventricular septum (r = -0.18; p < 0.05 and with the induration of the aortic valve (r = -0.18; p < 0.05; the square root mean squared of successive differences (RMSSD, ms for R–R intervals and the percentage of adjacent R–R intervals that varied by more than 50 ms (pNN50 correlated with the induration of the aortic valve (r = -0.23; p<0.05 and r = -0.25; p < 0.05, respectively, with the presence of pericarditis (r = -0.24; p < 0.05 and r = -0,27; p < 0.05, respectively, and with the level of pulmonary artery systolic pressure (r = -0

    Pain is a common but understudied quality of life concern in systemic sclerosis (SSc). This investigation sought to describe patient-reported pain during the early phase of the disease and to examine potential predictors of this over time. A prospective cohort (N = 316) of patients with early-disease SSc from the Genetics versus ENvironment In Scleroderma Outcome Study (GENISOS) were followed for 3 years. Multilevel modeling was used to describe longitudinal changes in pain and the extent to which pain variance was explained by disease type, emotional health, perceived physical health, health worry, and social support. Patient-reported pain remained relatively stable, with slight improvement over time. More severe disease type was associated with worse initial pain, but the association was reduced to nonsignificance after accounting for the psychosocial variables. Better emotional health and perceived physical health were associated with lower initial pain. There were marginal interactive effects for perceived physical health and social support such that initial perceptions of poorer physical health, and higher social support, were predictive of greater improvements in pain over time. These data suggest that emotional health, perceived physical health, and social support are more relevant to longitudinal SSc pain than disease severity and that perceived physical health and social support may impact pain trajectories. Researchers and rheumatology health professionals should consider these factors in comprehensive pain models and pain management protocols.

    Diagnosis of systemic sclerosis (SSc) is partially determined by the presence of specific autoantibodies often associated with specific clinical features. Recent studies report the presence of ACPA in SSc. We aimed to evaluate the prevalence of ACPA in SSc and to assess their influence on clinical presentation of SSc. A systematic literature search was performed using PubMed and Cochrane databases' publications between 1999 and March 2017. Search terms were: "systemic sclerosis [MeSH] AND (ACPA OR anti-CCP OR rheumatoid factor OR cohort OR value diagnostic)". In a first step, we selected cohorts with >50 SSc patients with ACPA identification, for ACPA frequency determination. In a second step, we included studies that analysed clinical profiles according to ACPA status. Meta-analyses were performed when at least two studies were available. First, we identified 13 observational studies with a total of 1231 SSc patients. The mean prevalence of ACPA in SSc was 9.2%. Secondly, we identified nine studies reporting clinical aspects according to ACPA status. Our meta-analyses showed a significant association between ACPA positivity and the presence of arthritis (odds ratio (OR)=22.48 [10.71-47.21]), joint erosions seen on X-rays (OR=14.79 [6.38-34.28]), pulmonary fibrosis (OR=2.75 [1.21-6.24]), oesophagus involvement (OR=2.72 [1.05-7.07]), and diffuse skin involvement (OR=2.21 [1.21-4.03]). The prevalence of ACPA in scleroderma is 9.2%. Our meta-analysis shows an increased risk for erosive arthritis, pulmonary fibrosis, oesophagus involvement and diffuse skin involvement, in patients with ACPA-positive SSc. ACPA should be systematically included in SSc assessment. Copyright © 2017 Société française de rhumatologie. Published by Elsevier SAS. All rights reserved.

    Highlights: • A quantitative CT parameter of lung parenchyma in systemic sclerosis is presented. • We examine the optimal percentage threshold for the percentile density. • The 85th percentile density threshold correlated significantly with lung function. • A lung structure–function relation is confirmed. • We report applicability of Perc85 in progression mapping of interstitial lung disease. - Abstract: Introduction: Interstitial lung disease occurs frequently in patients with systemic sclerosis (SSc). Quantitative computed tomography (CT) densitometry using the percentile density method may provide a sensitive assessment of lung structure for monitoring parenchymal damage. Therefore, we aimed to evaluate the optimal percentile density score in SSc by quantitative CT densitometry, against pulmonary function. Material and methods: We investigated 41 SSc patients by chest CT scan, spirometry and gas transfer tests. Lung volumes and the nth percentile density (between 1 and 99%) of the entire lungs were calculated from CT histograms. The nth percentile density is defined as the threshold value of densities expressed in Hounsfield units. A prerequisite for an optimal percentage was its correlation with baseline DLCO %predicted. Two patients showed distinct changes in lung function 2 years after baseline. We obtained CT scans from these patients and performed progression analysis. Results: Regression analysis for the relation between DLCO %predicted and the nth percentile density was optimal at 85% (Perc85). There was significant agreement between Perc85 and DLCO %predicted (R = −0.49, P = 0.001) and FVC %predicted (R = −0.64, P < 0.001). Two patients showed a marked change in Perc85 over a 2 year period, but the localization of change differed clearly. Conclusions: We identified Perc85 as optimal lung density parameter, which correlated significantly with DLCO and FVC, confirming a lung parenchymal structure–function relation in SSc. This provides

    Full Text Available Introduction. Anti-citrullinated peptides antibodies (ACPA are present in 80% of sera of rheumatoid arthritis (RA patients with high specificity for diagnosis and prediction for the development of early erosive arthritis. A few studies have reported a low frequency ACPA in systemic sclerosis (SSc patients with the presence of arthritis. Objective. The aim of our study was to determine the frequency of ACPA in systemic sclerosis (SSc patients, their correlation with clinical manifestations and radiographic features. Methods. The study included 82 patients with SSc, mean age 54.4 years, 59 with the limited (lSSc and 23 with the diffuse (dSSc form of the disease. The control group included 28 healthy age and sex matched subjects. ACPA and rheumatoid factor (RF were determined in all SSc patients and healthy subjects in whom standard radiography of hands and wrists was also done. Results. The presence of ACPA was detected in 11 (13.4% of SSc patients. Their level was not increased in any of the controls. Positive RF was found in 15.9% of SSc patients. Arthritis was present in 17.1%, as well as marginal bone erosions. There was a statistically significant association between positive ACPA and arthritis (p<0.0001 and positive ACPA and marginal bone erosions (p=0.0002. Conclusion. The research confirmed the correlation between ACPA with clinical signs of arthritis and radiographic damage of hand joints. ACPA is a useful diagnostic marker in the identification of SSc patients with arthritis and anatomic bone damage enabling the use of adequate therapy in order to prevent joint damage and poor quality of life.

    Full Text Available Fractalkine (FKN and its receptor CX3CR1 are critical mediators in the vascular and tissue damage of several chronic diseases, including systemic sclerosis (SSc and pulmonary arterial hypertension (PAH. Interestingly, the V249I and T280M genetic polymorphisms influence CX3CR1 expression and function. We investigated whether these polymorphisms are associated with PAH secondary to SSc. CX3CR1 genotypes were analyzed by PCR and sequencing in 76 patients with limited SSc and 204 healthy controls. PAH was defined by colorDoppler echocardiography. Homozygosity for 249II as well as the combined presence of 249II and 280MM were significantly more frequent in patients with SSc compared to controls (17 vs 6%, p = 0.0034 and 5 vs 1%, p = 0.0027, respectively. The 249I and 280M alleles were associated with PAH (odd ratio [OR] 2.2, 95% confidence interval [CI] 1.01-4.75, p = 0.028 and OR 7.37, 95%CI: 2.45-24.60, p = 0.0001, respectively. In conclusion, the increased frequencies of 249I and 280M CX3CR1 alleles in a subgroup of patients with SSc-associated PAH suggest a role for the fractalkine system in the pathogenesis of this condition. Further, the 249I allele might be associated with susceptibility to SSc.

    Glutamate excitotoxicity contributes to oligodendroglial and axonal damage in multiple sclerosis pathology. Extracellular glutamate concentration in the brain is controlled by cystine/glutamate antiporter (system xc-), a membrane antiporter that imports cystine and releases glutamate. Despite this, the system xc{sup -} activity and its connection to the inflammatory reaction in multiple sclerosis (MS) is largely unknown. Longitudinal in vivo magnetic resonance (MRI) and positron emission tomography (PET) imaging studies with 2-[{sup 18}F]Fluoro-2-deoxy-D-glucose ([{sup 18}F]FDG), [{sup 11}C]-(R)-1-(2-chlorophenyl)-N-methyl-N-1(1-methylpropyl) -3-isoquinolinecarbox amide ([{sup 11}C]PK11195) and (4S)-4-(3-{sup 18}F-fluoropropyl)-L-glutamate ([{sup 18}F]FSPG) were carried out during the course of experimental autoimmune encephalomyelitis (EAE) induction in rats. [{sup 18}F]FSPG showed a significant increase of system xc{sup -} function in the lumbar section of the spinal cord at 14 days post immunization (dpi) that stands in agreement with the neurological symptoms and ventricle edema formation at this time point. Likewise, [{sup 18}F]FDG did not show significant changes in glucose metabolism throughout central nervous system and [{sup 11}C]PK11195 evidenced a significant increase of microglial/macrophage activation in spinal cord and cerebellum 2 weeks after EAE induction. Therefore, [{sup 18}F]FSPG showed a major capacity to discriminate regions of the central nervous system affected by the MS in comparison to [{sup 18}F]FDG and [{sup 11}C]PK11195. Additionally, clodronate-treated rats showed a depletion in microglial population and [{sup 18}F]FSPG PET signal in spinal cord confirming a link between neuroinflammatory reaction and cystine/glutamate antiporter activity in EAE rats. Altogether, these results suggest that in vivo PET imaging of system xc{sup -} could become a valuable tool for the diagnosis and treatment evaluation of MS. (orig.)

    Higher latitude and human leukocyte antigen (HLA)-DRB1*04:05 increase susceptibility to multiple sclerosis (MS) in the Japanese population, but their effects on disease severity are unknown. We aimed to clarify the effects of latitude and the HLA-DRB1 and HLA-DPB1 genes on disease severity in Japanese patients with MS. We enrolled 247 MS patients and 159 healthy controls (HCs) from the northernmost main island of Japan, Hokkaido Island (42-45° north), and 187 MS patients and 235 HCs from the southern half (33-35° north) of the Japanese archipelago (33-45° north). We genotyped HLA-DRB1 and HLA-DPB1 alleles, compared demographic features, and analyzed factors contributing to differences in clinical and laboratory findings between MS patients from southern and northern Japan. The Multiple Sclerosis Severity Score (MSSS), which adjusts the Kurtzke's Expanded Disability Status Scale score according to disease duration, was used to estimate disease severity. The HLA-DRB1*04:05 and DRB1*15:01 alleles conferred susceptibility to MS in our Japanese population (p (corr) = 0.0004 and p (corr) = 0.0019, respectively). Southern patients had higher MSSS scores than northern patients (p = 0.003). Northern patients had higher frequencies of brain lesions meeting the Barkhof criteria (Barkhof brain lesions) and cerebrospinal fluid (CSF) IgG abnormalities than southern patients (p = 0.0012 and p < 0.0001, respectively). DRB1*04:05-positive MS patients had lower MSSS scores and lower frequencies of Barkhof brain lesions and CSF IgG abnormalities than DRB1*04:05-negative MS patients (p = 0.0415, p = 0.0026, and p < 0.0001, respectively). Multivariate analyses revealed that latitude and DRB1*04:05 were independently associated with the lowest quartile of MSSS and that latitude was positively associated with Barkhof brain lesions and CSF IgG abnormalities. DRB1*04:05 was negatively associated with these parameters. MSSS was decreased by 0.57 per DRB1

    Full Text Available Multiple sclerosis (MS is a chronic inflammatory and demyelinating disease of autoimmune originate. The main agents responsible for the MS development include exogenous, environmental, and genetic factors. MS is characterized by multifocal and temporally scattered central nervous system (CNS damage which lead to the axonal damage. Among clinical courses of MS it can be distinguish relapsing-remitting multiple sclerosis (RRMS, secondary progressive multiple sclerosis (SPSM, primary progressive multiple sclerosis (PPMS, and progressive-relapsing multiple sclerosis (RPMS. Depending on the severity of signs and symptoms MS can be described as benign MS or malignant MS. MS diagnosis is based on McDonald’s diagnostic criteria, which link clinical manifestation with characteristic lesions demonstrated by magnetic resonance imaging (MRI, cerebrospinal fluid (CSF analysis, and visual evoked potentials. Among CSF laboratory tests used to the MS diagnosis are applied: Tibbling & Link IgG index, reinbegrams, and CSF isoelectrofocusing for oligoclonal bands detection. It should be emphasized, that despite huge progress regarding MS as well as the availability of differentdiagnostics methods this disease is still a diagnostic challenge. It may result from fact that MS has diverse clinical course and there is a lack of single test, which would be of appropriate diagnostic sensitivity and specificity for quick and accurate diagnosis.

    The objective of this study was to evaluate the efficacy of the endothelin receptor antagonist, bosentan, in patients with Raynaud's phenomenon secondary to systemic sclerosis never treated with prostanoids and without digital ulcers. The study design is a preliminary, prospective open label trial. The patients recruited took one 62.5 mg dose of bosentan twice daily for 4 weeks, followed by 125 mg twice daily for 24 weeks. Of the 10 patients recruited, all completed the study. The reduction in Raynaud's phenomenon attacks at week 24 from the baseline was statistically significant (Δ-1.3, P=0.0126). The Raynaud's condition score showed a statistically significant improvement (Δ-1.4, P=0.0279), as did the visual analog pain scale (Δ-1.5, P=0.0016) at the 24th week. Bosentan appears to be effective and may be a valid alternative for the treatment of severe secondary Raynaud's phenomenon for patients where prostanoids therapy is contraindicated or refused.

    Full Text Available Widespread vasculopathy and profound fibrosis are key features of the pathogenesis of systemic sclerosis (SSc. We hypothesized that the TNF-like weak inducer of apoptosis (TWEAK, a recently recognized multifunctional cytokine which regulates angiogenesis and tissue remodeling, may play a role in the development of SSc. The production of TWEAK by the peripheral blood mononuclear cells (PBMC was investigated, by means of ELISA, in 24 SSc patients and 14 healthy subjects. Moreover, production of TWEAK was correlated with clinical features of SSc. PBMC were isolated using density gradient centrifugation on Histopaque and were cultured in FCS supplemented RPMI medium at 37 degrees C under 5% CO2. Production of TWEAK by PBMC was significantly diminished in patients with more severe microvascular damage, as indicated by the presence of "active" capillaroscopic pattern, compared with SSc patients with less pronounced microangiopathy ("slow" pattern, and healthy subjects. Moreover production of TWEAK correlated inversely with duration of Raynaud's phenomenon. PBMC from patients with scleroderma-related interstitial lung disease tended to produce lower amounts of TWEAK compared with SSc patients without lung involvement but the difference was not significant. The results of our study suggest that diminished production of TWEAK might play a role in the pathogenesis of vascular injury in SSc patients. Whether TWEAK may represent a new therapeutic target in SSc requires further studies.

    Multiple sclerosis (SM) is the most frequent inflammatory-demyelinating disease of central nervous system. The character of SM disease provokes that its most frequent symptoms are vertigo, equilibrium disorders and ataxia. Objective method of vertigo estimation is evaluation of the nystagmus via videonystagmography registration (VNG). This examination allows to simultaneously assess the vertical and horizontal component of the nystagmus. It is considered that mainly the vertical nystagmus is characteristic to equilibrium system impairments of the central nervous system, caused also by SM. The study was carried out on 40 patients (28 women, 12 men) with SM diagnosed as a result of neurological examination. 7 patients (17.5%) suffered from sham - movement vertigo, while 33 patients (82.5%) suffered from instability of posture and walking deviation. The videonystagmography examination resulted in the following: deviation of the eye movement was recorded in 26 patients (65%) during either in saccadic test and in smooth pursuit test, optokinetic nystagmus recorded: dissymetric and variable amplitude result in 24 patients (60%), presence of vertical nystagmus component in 30 patients (75%), positional test: directional-changable nystagmus in 8 patients (20%), pendular nystagmus in 4 patients (10%), presence of vertical nystagmus component in 31 patients (77.5%), caloric test: impairments of one of the labyrinth recorded in 12 patients (30%). SM is still the diagnostic and therapeutic problem. During the mentioned tests we have found the quantitative and qualitative changes in VNG recordings. This may be helpful in SM diagnosis, mainly during its early stages.

    Fatigue is reported as the most common symptom by patients with multiple sclerosis (MS). The physiological and functional parameters related to fatigue in MS patients are currently not well established. A new wearable wireless body measurement system, named Fatigue Monitoring System (FAMOS), was developed to study fatigue in MS. It can continuously measure electrocardiogram, body-skin temperature, electromyogram and motions of feet. The goal of this study is to test the ability of distinguishing fatigued MS patients from healthy subjects by the use of FAMOS. This paper presents the realization of the measurement system including the design of both hardware and dedicated signal processing algorithms. Twenty-six participants including 17 MS patients with fatigue and 9 sex- and age-matched healthy controls were included in the study for continuous 24 h monitoring. The preliminary results show significant differences between fatigued MS patients and healthy controls. In conclusion, the FAMOS enables continuous data acquisition and estimation of multiple physiological and functional parameters. It provides a new, flexible and objective approach to study fatigue in MS, which can distinguish between fatigued MS patients and healthy controls. The usability and reliability of the FAMOS should however be further improved and validated through larger clinical trials.

    Systemic sclerosis (SSc; scleroderma) is associated with a wide periodontal ligament (PDL) and mandibular erosions. We investigated the clinical correlates of SSc with these radiologic abnormalities. Subjects from the Canadian Scleroderma Research Group cohort underwent detailed radiologic examinations. Associations between radiologic abnormalities and clinical manifestations of SSc were examined with univariate and multivariate analyses. The study included 159 subjects; 90.6% were women, the mean ± SD age was 56 ± 10 years, diffuse disease was present in 28.3%, and mean ± SD disease duration was 13.7 ± 8.4 years. Widening of the PDL involving at least 1 tooth was present in 38% of subjects, and 14.5% had at least 1 site in the mandible with an erosion. In analyses adjusting for age, disease duration, sex, smoking, and education, we found significant associations between the number of teeth with widening of the PDL and disease severity assessed by the physician global assessment (PGA) (relative risk [RR] 1.19, 95% confidence interval [95% CI] 1.02-1.39, P = 0.028). Analyses replacing the PGA with the skin score, disease subset, or anti-topoisomerase I antibodies confirmed the relationship with indices of disease severity. There was no relationship between either the number of teeth with periodontal disease or the number of missing teeth, and the number of teeth with wide PDL. A smaller interdental distance (RR 0.89, 95% CI 0.82-0.97, P = 0.006), but not disease severity, facial skin score, or ischemia was associated with a larger number of erosions. In SSc, a wide PDL may reflect generalized overproduction of collagen, and mandibular erosions are related to local factors in the oral cavity. © 2016, American College of Rheumatology.

    Full Text Available ABSTRACT Introduction: Systemic sclerosis (SSc is an autoimmune disease of the connective tissue characterized by the triad of vascular injury, autoimmunity (cellular and humoral and tissue fibrosis. It is estimated that musculoskeletal pain is a common complaint of patients with SSc, ranging from 40 to 80%, and mainly in patients with early diffuse disease. Arthritis, clinically observed, may be a feature seen in the presentation of SSc, often leading to early diagnostic errors with rheumatoid arthritis (RA. In the course of the disease, arthritis is observed in 24–97% of patients with SSc. Objectives: To correlate the occurrence or nonoccurrence of arthritis in patients with SSc of the Midwest region of Brazil with possible distinct clinical and laboratory manifestations observed in three groups of patients. To report the frequency of true association between systemic sclerosis and rheumatoid arthritis in patients with clinically and radiologically observed synovitis. Methods: Sixty-one SSc patients were subsequently assessed every 3 months within 1 year, in order to clinically observe the occurrence of synovitis and its patterns of progression. Patients were divided into 3 groups: 41 patients with SSc without arthritis, 16 SSc patients with arthritis and 4 patients with overlap of SSc and RA. All patients underwent a radiological examination of the hands at the end of the study. Results: Among all patients evaluated, we found a female predominance (98.7%, mean age of 50.94 years, white color (49.2%, limited form of the disease (47.6%, time of diagnosis between 5 and 10 years (47.6% and duration of the disease of 8.30 years.

    Currently, there is no satisfactory treatment for Raynaud's phenomenon (RP) in systemic sclerosis (SSc). Recently, it has been reported that botulinum toxin A (BTX-A) injection was effective for the treatment of RP in SSc patients. The objective was to assess the efficacy and safety of BTX-A on RP in Japanese SSc patients. In the prospective, case series study, 10 Japanese SSc patients with RP received 10 U of BTX-A injections into the hand. The change in severity of RP, including the frequency of attacks/pain, color changes, duration time of RP and the severity of pain, was assessed by Raynaud's score and pain visual analog scale (VAS) at each visit during 16 weeks. The recovery of skin temperature 20 min after cold water stimulation was examined by thermography at baseline and 4 weeks after injection. The number of digital ulcers (DU) and adverse effects were assessed at each visit. BTX-A injection decreased Raynaud's score and pain VAS from 2 weeks after injection, and the suppressive effect was continued until 16 weeks after injection. Skin temperature recovery after cold water stimulation at 4 weeks after injection was significantly enhanced compared with that before injection. All DU in five patients were healed within 12 weeks after injection. Neither systemic nor local adverse effects were observed in all cases. We conclude that BTX-A injection significantly improved the activity of RP in SSc patients without any adverse events, suggesting that BTX-A may have possible long-term preventive and therapeutic potentials for RP in Japanese SSc patients. © 2015 Japanese Dermatological Association.

    Undifferentiated connective tissue disease at risk for systemic sclerosis (UCTD-risk-SSc), otherwise referred to as very early-early SSc, is a condition characterized by Raynaud's phenomenon with serum SSc marker autoantibodies and/or typical capillaroscopic findings and unsatisfying classification criteria for the disease. The aim of the present study was to assess the prevalence of right (RV) or left ventricular (LV) systolic and/or diastolic dysfunction by standard echocardiography and tissue Doppler imaging (TDI). Thirty patients with UCTD-risk-SSc (28 female, mean age 47 ± 13 years, range 21-70) and 30 age- and sex-matched controls underwent cardiac assessment by standard echocardiography and TDI. UCTD-risk-SSc patients and controls did not show any difference at standard echocardiography. Despite results falling within the respective normal ranges, TDI pointed out a mild impairment of LV and RV diastolic (E m 15 ± 4 vs. 19 ± 5, p = 0.0004; E/E m 6.1 ± 1.7 vs. 4.8 ± 1.2, p = 0.001; E t 14 ± 3 vs. 16 ± 2, p = 0.02; E t /A t 0.9 ± 0.4 vs. 1.3 ± 0.3, p = 0.002; E/E t 3.5 ± 1.2 vs. 4.2 ± 0.9, p = 0.02) and systolic function (S m 13 ± 3 vs. 15 ± 2 cm/s, p risk-SSc patients as compared to controls. Notably, a statistically significant difference also emerged in the prevalence of TDI detected E'/A' t , (71% of UCTD-risk-SSc patients vs. 19% of controls; p risk-SSc patients show a previously unrecognized, mild biventricular systolic and diastolic dysfunction as compared to controls. The pathophysiologic meaning as well the predictive value of developing overt SSc await to be elucidated.

    Objective: To investigate the relationship between endothelial vasoactive factors and development of systemic sclerosis (SSc). Methods: Blood circulating endothelial cell count (CEC, with density gradient precipitation method); plasma endothelin (ET), thromboxane B 2 (TXB 2 ), 6-keto-prostaglandin F 1α concentrations (all above three with RIA); nitric oxide (NO) contents (with Griss method) and plasma intercellular adhesion molecule-1 (ICAM-1), p-selectin (P-S) contents (with ELISA) were measured in 52 patients with systemic sclerosis (SSc) both before and after treatment with prostaglandin E1 and 30 controls. Results: Plasma ET, TXB 2 , ICAM-1, P-S contents and CEC were significantly higher and plasma NO, 6-K-PGF 1α contents were significantly lower in all the patients with SSc before treatment than those in the controls, After treatment, the patients with satisfactory responses (n=33) had the abnormal plasma values of these parameters greatly corrected (vs before treatment P<0.05, P<0.01); while poorly responding patients had the plasma values little changed. Conclusion: Endothelial vasoactive factors are closely involved in the development of systemic sclerosis and may be used as predictors of treatment efficiency. (authors)

    Objective: To describe the high-resolution computed tomography findings in the lung of patients with systemic sclerosis, independently of the respiratory symptoms. Materials and methods: Seventy-three high-resolution computed tomography scans of 44 patients with clinical diagnosis of systemic sclerosis were reviewed and defined by the consensus of two radiologists. Results: Abnormalities were seen in 91.8% (n = 67) of the scans. The most frequent findings were reticular pattern (90.4%), ground-glass opacities (63%), traction bronchiectasis and bronchiolectasis (56.2%), esophageal dilatation (46.6%), honeycombing pattern (28.8%) and signs of pulmonary hypertension (15.6%). In most cases the lesions were bilateral (89%) and symmetrical (58.5%). The lesions were predominantly located in the basal (91.2%) and peripheral (92.2%) regions. Conclusion: In the majority of the patients, progressive systemic sclerosis can cause pulmonary fibrosis mainly characterized by reticular pattern with basal and peripheral distribution on high-resolution computed tomography.

    Full Text Available Background: Despite the importance of traditional pulmonary function tests (PFTs in managing systemic sclerosis (SSc, many patients with pulmonary disease diagnosed by computed tomography (CT present with normal PFTs. Objective: To evaluate the efficacy of the nitrogen single-breath washout (N2SBW test in diagnosing SSc and to correlate N2SBW parameters with the PFT indexes used in the follow-up of these patients, clinical data, and CT findings. Methods: Cross-sectional study in which 52 consecutive SSc patients were subjected to spirometry, body plethysmography, analysis of the diffusing capacity for carbon monoxide (DLCO, analysis of respiratory muscle strength, N2SBW testing, and CT analysis. Results: Twenty-eight patients had a forced vital capacity (FVC that was 120% of the predicted value, while 15 patients had a closing volume/vital capacity (CV/VC that was >120% of the predicted value. A significant difference in Phase III slopeN2SBW was observed when the patients with predominant traction bronchiectasis and honeycombing were compared to the patients with other CT patterns (p < 0.0001. The Phase III slopeN2SBW was correlated with FVC (rs = −0.845, p < 0.0001 and DLCO (rs = −0.600, p < 0.0001, and the CV/VC was correlated with FVC (rs = −0.460, p = 0.0006 and residual volume/total lung capacity (rs = 0.328, p = 0.017. Conclusion: Ventilation heterogeneity is a frequent finding in SSc patients that is associated with restrictive damage, changes in pulmonary diffusion, and CT patterns. In addition, approximately one-third of the patients presented with findings that were compatible with small airway disease.

  1. Serum amyloid A is a marker for pulmonary involvement in systemic sclerosis.

    Directory of Open Access Journals (Sweden)

    Full Text Available Inflammation in systemic sclerosis (SSc is a prominent, but incompletely characterized feature in early stages of the disease. The goal of these studies was to determine the circulating levels, clinical correlates and biological effects of the acute phase protein serum amyloid A (SAA, a marker of inflammation, in patients with SSc. Circulating levels of SAA were determined by multiplex assays in serum from 129 SSc patients and 98 healthy controls. Correlations between SAA levels and clinical and laboratory features of disease were analyzed. The effects of SAA on human pulmonary fibroblasts were studied ex vivo. Elevated levels of SAA were found in 25% of SSc patients, with the highest levels in those with early-stage disease and diffuse cutaneous involvement. Significant negative correlations of SAA were found with forced vital capacity and diffusion capacity for carbon monoxide. Patients with elevated SAA had greater dyspnea and more frequent interstitial lung disease, and had worse scores on patient-reported outcome measures. Incubation with recombinant SAA induced dose-dependent stimulation of IL-6 and IL-8 in normal lung fibroblasts in culture. Serum levels of the inflammatory marker SAA are elevated in patients with early diffuse cutaneous SSc, and correlate with pulmonary involvement. In lung fibroblasts, SAA acts as a direct stimulus for increased cytokine production. These findings suggest that systemic inflammation in SSc may be linked to lung involvement and SAA could serve as a potential biomarker for this complication.

  2. Does dysfunction of the mirror neuron system contribute to symptoms in amyotrophic lateral sclerosis?

    2015-07-01

    There is growing evidence that mirror neurons, initially discovered over two decades ago in the monkey, are present in the human brain. In the monkey, mirror neurons characteristically fire not only when it is performing an action, such as grasping an object, but also when observing a similar action performed by another agent (human or monkey). In this review we discuss the origin, cortical distribution and possible functions of mirror neurons as a background to exploring their potential relevance in amyotrophic lateral sclerosis (ALS). We have recently proposed that ALS (and the related condition of frontotemporal dementia) may be viewed as a failure of interlinked functional complexes having their origins in key evolutionary adaptations. This can include loss of the direct projections from the corticospinal tract, and this is at least part of the explanation for impaired motor control in ALS. Since, in the monkey, corticospinal neurons also show mirror properties, ALS in humans might also affect the mirror neuron system. We speculate that a defective mirror neuron system might contribute to other ALS deficits affecting motor imagery, gesture, language and empathy.

    2012-01-01

    Full Text Available Amyotrophic lateral sclerosis (ALS is a heterogeneous group of incurable motor neuron diseases (MNDs characterized by a selective loss of upper and lower motor neurons in the brain and spinal cord. Most cases of ALS are sporadic, while approximately 5–10% cases are familial. More than 16 causative genes for ALS/MNDs have been identified and their underlying pathogenesis, including oxidative stress, endoplasmic reticulum stress, excitotoxicity, mitochondrial dysfunction, neural inflammation, protein misfolding and accumulation, dysfunctional intracellular trafficking, abnormal RNA processing, and noncell-autonomous damage, has begun to emerge. It is currently believed that a complex interplay of multiple toxicity pathways is implicated in disease onset and progression. Among such mechanisms, ones that are associated with disturbances of protein homeostasis, the ubiquitin-proteasome system and autophagy, have recently been highlighted. Although it remains to be determined whether disease-associated protein aggregates have a toxic or protective role in the pathogenesis, the formation of them results from the imbalance between generation and degradation of misfolded proteins within neuronal cells. In this paper, we focus on the autophagy-lysosomal and endocytic degradation systems and implication of their dysfunction to the pathogenesis of ALS/MNDs. The autophagy-endolysosomal pathway could be a major target for the development of therapeutic agents for ALS/MNDs.

    Some authors consider that morphoea and systemic sclerosis (SSc) could be part of the same disease spectrum. The aim of this study was to analyse the prevalence of signs indicative of SSc in a cohort of patients with morphoea. This is a prospective multi-centre study performed in four French academic dermatology departments: 76 patients with morphoea and 101 age- and sex-matched controls, who underwent complete clinical examination, were enrolled. A systemic search for signs indicative of SSc (e.g. Raynaud's phenomenon, reflux) was performed with the help of a standardised questionnaire. There were 58 women and 18 men (ration=3/1) with a median age of 59 years. Mean age at diagnosis was 54 years (extremes, 13-87). 49 subjects had plaque morphoea, 9 had generalised morphoea and 18 had linear morphoea. Mean duration of morphoea was 7.9 years. Signs possibly indicative of SSc were noted in four patients of the control group and in 8 patients with morphoea. This difference was not statistically significant (p=0.129). Further investigations ruled out SSc in all patients. Signs indicative of SSc are statistically not more frequently present in patients with morphoea than in controls and this study does not support the view that those 2 entities are part of a common disease spectrum.

    Full Text Available Introduction. Posterior Reversible Encephalopathy Syndrome (PRES is an increasingly recognized clinical and radiological entity with a wide spectrum of symptoms. Its mechanism depends on failure of the blood-brain barrier due to high systemic blood pressure (BP and loss of integrity of vascular endothelium related with different triggers. Methods. We aim to report a case of PRES induced by arterial hypertension and very early systemic sclerosis (SSc not previously known. Results. A 64-year-old female was admitted due to 1-week pulsating headache more prominent on frontal scalp, accompanied by phonophobia, photophobia, and facial flushing. Neurological exam revealed brisk deep tendon reflex. Brain magnetic resonance imaging (MRI showed subcortical lesions mainly located in posterior regions. BP was monitored and episodic arterial hypertension was detected. In laboratory tests positive anti-topoisomerase I antibodies were detected. BP was controlled with angiotensin-converting-enzyme inhibitors and headache improved. In a new MRI a month later improvement of white matter lesions was observed. Capillaroscopy showed “active pattern,” considered typical of SSc. Conclusion. In SSc anti-endothelial cell antibodies impair vascular endothelium and liberation of vasoconstrictors leads to BP increasing and disruption of blood-brain barrier autoregulation mechanisms. PRES can be the first manifestation of very early SSc and this entity should be considered even in absence of skin lesions or Raynaud phenomenon.

    Full Text Available FUNDAMENTOS: A capilaroscopia periungueal tem sido largamente utilizada para diagnóstico de esclerodermia sistêmica. Mais recentemente descobriu-se que também pode predizer o envolvimento de órgãos internos. OBJETIVO: Verificar se a capilaroscopia periungueal mostra correlação com a gravidade da esclerodermia sistêmica. MÉTODOS: Foram estudados a capilaroscopia periungueal de 14 pacientes com esclerodermia sistêmica quanto ao número médio de capilares dilatados e às áreas de desvascularização; a medida do envolvimento cutâneo pelo índice de Rodnan modificado; e o grau de gravidade da doença segundo escala proposta por Medsger e cols. RESULTADOS: Os resultados mostraram boa correlação do índice de desvascularização com o grau de gravidade da doença (p = 0.04. Não se encontrou correlação entre o aparecimento de dilatação capilar e o grau de gravidade da doença (p = 0.572. O grau de espessamento cutâneo não mostrou correspondência com o grau de dilatação capilar (p = 0.76, embora mostrasse tendência de associação com desvascularização (p = 0.07. CONCLUSÃO: Os autores concluem que a presença de desvascularização à capilaroscopia periungueal pode ser usada como elemento indicador de maior gravidade da esclerodermia sistêmica.BACKGROUND: Nail fold capillaroscopy has been largely used in the diagnosis of systemic sclerosis. It has been recently discovered that this test is also able to predict internal organ damage in systemic sclerosis. OBJECTIVE: This study was carried out to verify whether nail fold capillaroscopy findings are correlated with disease severity. METHODS: We studied nail fold capillaroscopy findings regarding dilated and avascular areas from 14 patients with systemic sclerosis; degree of skin involvement by means of a modified Rodnan index; and disease severity with the scale proposed by Medsger et al. RESULTS: The results showed that the number of avascular areas has a good correlation

    This paper describes the application of a novel unsupervised pattern recognition system to the classification of the Visual Evoked Potentials (VEP's) of normal and multiple sclerosis (MS) patients. The method combines a traditional statistical feature extractor with a fuzzy clustering method, all implemented in a parallel neural network architecture. The optimization routine, ALOPEX, is used to train the network while decreasing the likelihood of local solutions. The unsupervised system includes a feature extraction and clustering module, trained by the optimization routine ALOPEX. Through maximization of the output variance of each node, and an architecture which excludes redundancy, the feature extraction network retains the most significant Karhunen-Loeve expansion vectors. The clustering module uses a modification to the Fuzzy c-Means (FCM) clustering algorithms, where ALOPEX adjusts a set of cluster centers to minimize an objective error function. The result combines the power of the FCM algorithms with the advantage of a more global solution from ALOPEX. The new pattern recognition system is used to cluster the VEP's of 13 normal and 12 MS subjects. The classification with this technique can, without supervision, separate the patient population into two groups which largely correspond to the MS and control subject groups. A suitable threshold can be chosen so that the recognizer chooses no false negatives. The use of multiple stimulation patterns appears to improve the reliability of the decision. The reasoning of most neural networks in their decision making cannot easily be extracted upon the completion of training. However, due to the linearity of the network nodes, the cluster prototypes of this unsupervised system can be reconstructed to illustrate the reasoning of the system. In this application, this analysis hints at the usefulness of previously unused portions of the VEP in detecting MS. It also indicates a possible use of the system as a training

    Lymphatic supermicrosurgery or supermicrosurgical lymphaticovenular anastomosis (LVA) is becoming popular for the treatment of compression-refractory upper extremity lymphedema (UEL) with its effectiveness and minimally invasiveness. In conventional LVA, superficial lymphatic vessels are used for anastomosis, but its treatment efficacy would be minimum when superficial lymphatic vessels are severely sclerotic. Theoretically, deep lymphatic vessels can be used for LVA, but no clinical case has been reported regarding deep lymphatic vessel-to-venous anastomosis (D-LVA). We report a breast cancer-related UEL case treated with D-LVA, in which a less-sclerotic deep lymphatic vessel was useful for anastomosis but superficial lymphatic vessels were not due to severe sclerosis. A 62-year-old female suffered from an 18-year history of compression-refractory right UEL after right breast cancer treatments, and underwent LVA under local infiltration anesthesia. Because superficial lymphatic vessels found in surgical fields were all severely sclerotic, a deep lymphatic vessel was dissected at the cubital fossa. A 0.50-mm deep lymphatic vessel running along the brachial artery was supermicrosurgically anastomosed to a nearby 0.40-mm vein. At postoperative 12 months, her right UEL index decreased from 134 to 118, and she could reduce compression frequency from every day to 1-2 days per week to maintain the reduced lymphedematous volume. D-LVA may be a useful option for the treatment of compression-refractory UEL, when superficial lymphatic vessels are severely sclerotic. © 2015 Wiley Periodicals, Inc.

    Abstract Rationale: Sildenafil, a phosphodiesterase-5-inhibitor and Bosentan, an endothelin-1-receptor antagonist combined therapy could have beneficial effect in systemic sclerosis (SSc) patients with peripheral artery disease. Patient concerns: We report a case of a 48-year-old Black woman, who developed severe left limb claudication and walking limitation following a left femoropopliteal bypass occlusion in 2014. She was a heavy smoker and had a history of right middle cerebral artery ischemic stroke and bilateral Raynaud phenomenon. Diagnoses: According to the American College of Rheumatology/European League Against Rheumatism-2013 criteria, diagnosis of limited cutaneous SSc was retained with macrovascular lesions. She was referred for investigation of left limb claudication on treadmill using transcutaneous oxygen pressure measurement during exercise to argue for the vascular origin of the walking impairment. She had a severe left limb ischemia and the maximum walking distance (MWD) she reached was 118 m in March 2015 despite the medical optimal treatment and walking rehabilitation. Interventions: Sildenafil, 20 mg tid, was introduced due to active digital ulcers. In July 2015, the MWD increased to 288 m, then to 452 m in December 2015. Adding Bosentan to Sildenafil to prevent recurrent digital ulcers resulted in an MWD of 1576 m. Outcomes: Recently, the patient is treated with the combined therapy. She has no more pain during walking and his quality of life has improved. Lessons: Sildenafil and Bosentan combined therapy was associated in our case with an improvement of MWD without adverse effect. Further clinical trials are necessary to confirm our original observation. PMID:28640077

    Background/aim: The pathogenesis of Raynaud's phenomenon (RP) has not yet been fully elucidated. RP is characterized by exaggerated cold-induced vasoconstriction. Urotensin II (UII) is a potent vasoconstrictor. The aim of the present study was to evaluate plasma UII levels in both primary RP and secondary RP associated with systemic sclerosis (SSc).Materials and methods: Fifteen patients with primary RP, 30 patients with RP secondary to SSc, and 30 healthy controls (HC) were included in the study. Raynaud condition scores (RCS) were determined in the primary RP and SSc groups. Modified Rodnan skin score (MRSS) was determined for the SSc patients. Plasma UII level was analyzed by the ELISA method. Results: When compared to the HC group, plasma UII level was lower in the secondary RP group, but not in the primary RP group. Plasma UII level was not directly related to RCS in either the primary or secondary RP group. Moreover, it was not correlated with MRSS in the secondary RP group.Conclusion: The results of the present study suggest that UII is not associated with primary RP. Its level was lower in the secondary RP (SSc) patients. Therefore, it can be concluded that decreased UII level is related to SSc instead of RP.

    Objectives. To examine the characteristics of our patients with limited systemic sclerosis (lSSc) for differences between Barnett Type 1 (sclerodactyly only) and Type 2 or intermediate (acrosclerosis-distal but may reach up to elbows and/or knees plus face) subsets. Methods. Records of patients between January 1, 2000, and December 31, 2011, with SSc or those with anti-Scl-70, anticentromere, or antinucleolar antibodies were reviewed. Only cases fulfilling ACR 1980 criteria were included and classified as diffuse or limited according to LeRoy's criteria. Limited SSc was separated into sclerodactyly and acrosclerosis (Barnett's Types 1 and 2). Results. 234 SSc patients (216 females) fulfilled criteria. Female/male ratio was 12 : 1; 24% had dSSc and 76% lSSC (64% Type 1 and 12% Type 2). Total follow-up was 688 patient-years. Within lSSC, the Type 2 group had significantly shorter duration of Raynaud's and more anti-Scl-70 and less anticentromere antibodies. In particular, interstitial lung disease (ILD) was significantly more prevalent in Type 2 group and similar to Type 3. Conclusions. These results appear to confirm that extension of skin involvement within limited SSc may identify two different subsets with clinical and serologic characteristics. PMID:25435879

    Patients with systemic sclerosis (SSc) experience reduced exercise capacity and muscle strength compared with healthy subjects. There are also indications of reduced levels of physical activity. To present the current knowledge of physical exercise in SSc. Most studies presently available [three case studies, one single subject experimental design, one study comparing patients with healthy controls, one quasi experimental design (pre-post), two clinical trials and two random controlled trials] have included small samples of patients, mostly composed of patients with and without pulmonary involvement. It seems that patients with SSc without pulmonary involvement are able to perform and benefit from aerobic exercises of at least moderate intensity. Exercise tolerance, aerobic capacity, walking distance, muscle strength and muscle function as well as health-related quality of life (HRQL) have been found to be improved after participation in programmes including aerobic exercise and aerobic exercise combined with resistance exercises. Improvements seem to be only partially retained at follow up. Patients with pulmonary involvement may also experience improved muscle strength, physical and aerobic capacity, as well as HRQL following exercise. Patients with SSc without pulmonary involvement can be recommended to be as physically active as the general population. Patients with mild pulmonary involvement can be recommended to be physically active by engaging in exercises of moderate intensity and to participate in moderate-load resistance exercises. Health professionals should inform patients with SSc about the importance of physical activity and avoidance of a sedentary lifestyle. Copyright © 2017 John Wiley & Sons, Ltd.

    Recent studies show an association between autoimmune thyroiditis and systemic sclerosis (SSc) and suggest that this condition may interfere with the ES phenotype. However these studies evaluate the autoimmune thyroiditis as a whole and none of them specifically addresses Hashimoto's thyroiditis (HT) in SSc. To investigate the presence of HT in SSc patients and its possible association with disease manifestations. Clinical manifestations of hypothyroidism, TSH and anti-thyroid auto antibodies (anti-TPO. anti TBG and TRAb) were studied in 56 patients with SSc. SSc patients with HT were compared with SSc patients without thyroiditis. HT was observed in 19.64% of patients with SSc. No association was observed between HT and the different forms of disease or profile of autoantibodies. Likewise, there was no difference between the mean modified Rodnan score and presence of Raynaud's phenomenon, scars, digital necrosis, myositis, arthritis, sicca symptoms, esophageal dysmotility and scleroderma renal crisis when the groups were compared. On the other hand, patients with HT had higher frequency of pulmonary hypertension in relation to patients without HT (66.6% vs 22.5%, p=0.016). In the studied sample patients with ES and HT had higher prevalence of pulmonary hypertension. Long-term follow-up studies with a larger number of TH and SSc patients are needed to confirm these data. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

    Full Text Available Abstract Background Extracellular gelsolin (GSN and GC-globulin/Vitamin D-binding protein (DBP appear to play an important role in clearing the actin from extracellular fluids and in modulating cellular responses to anionic bioactive lipids. In this study we hypothesized that cellular actin release and/or increase in bioactive lipids associated with multiple sclerosis (MS development will translate into alteration of the actin scavenger system protein concentrations in blood and cerebrospinal fluid (CSF of patients with MS. Methods We measured GSN and DBP concentrations in blood and CSF obtained from patients diagnosed with MS (n = 56 in comparison to a control group (n = 20 that includes patients diagnosed with conditions such as idiopathic cephalgia (n = 11, idiopathic (Bell's facial nerve palsy (n = 7 and ischialgia due to discopathy (n = 2. GSN and DBP levels were measured by Western blot and ELISA, respectively. Results We found that the GSN concentration in the blood of the MS group (115 ± 78 μg/ml was significantly lower (p Conclusions The decrease of GSN concentration in blood and CSF of MS subjects suggests that this protein may be involved in chronic inflammation associated with neurodegeneration. Additionally, the results presented here suggest the possible utility of GSN evaluation for diagnostic purposes. Reversing plasma GSN deficiency might represent a new strategy in MS treatment.

    Full Text Available Objectives: To evaluate the prevalence and clinical significance of cathepsin G antibodies in patients affected with systemic sclerosis (SSc, scleroderma. Methods: 115 patients affected by SSc, 55 (47,8% with diffuse scleroderma (dSSc and 60 (52,2% with limited scleroderma (lSSc, were tested for cathepsin G antibodies by ELISA method. Moreover these sera were evaluated by indirect immunofluorescence (IIF on ethanol and formalin fixed human neutrophils. Results: By means of the ELISA method 16 (13,9% patients were found to be sera positive for anti-cathepsin G, 2 (12.5% of which showed a perinuclear fluorescence pattern (P-ANCA and 4 (25% an atypical ANCA staining, while 10 (62,5% were negative on IIF. The IIF on scleroderma sera revealed 5 (4,3% P-ANCA and 18 (15,7% atypical ANCA patterns. The anti-cathepsin G antibodies significantly prevailed in scleroderma sera (p=0.02 when their frequency was compared with that of healthy controls; while they were not significantly associated to any clinical or serological features of SSc patients. Conclusions: The anti-cathepsin G antibodies were significantly frequent in scleroderma sera; however, no clinical correlations were found. Thus, the significance of their presence in SSc still needs to be clarified.

    Systemic sclerosis (SSc) is a well-established disease associated with primary biliary cholangitis (PBC). However, the original 1980 American College of Rheumatology (ACR) criteria have poor sensitivity, especially for the detection of earlier SSc in previous studies. The objective was to evaluate the prevalence of SSc in patients with PBC using more sensitive 2001 LeRoy and Medsger criteria and the 2013 ACR/European League Against Rheumatism (EULAR) classification criteria. The secondary objective was to evaluate the frequency of individual clinical features. One hundred consecutive patients with PBC without previously diagnosed SSc were recruited between 2005 and 2007 from a tertiary care gastroenterology clinic. All patients underwent a complete clinical examination, determination of SSc-specific antibodies, and a nailfold capillary microscopy. Fulfillment of the 3 different criteria sets was analyzed, along with individual disease features. Of 100 patients with PBC, 1% met the ACR 1980 criteria, 22% met the 2001 LeRoy and Medsger criteria for early SSc, and 17% the 2013 ACR/EULAR criteria. Raynaud phenomenon, SSc-related antibodies, and SSc capillaroscopic patterns were the most prevalent findings, with the highest sensitivities to help guide future screening. Our data show a high prevalence of SSc in patients with PBC with probable underestimation by previous studies using the original ACR criteria. Comorbid SSc should be actively searched for based on newly described criteria to improve detection and increase benefits of earlier treatment.

    According to the existence of subclinical organ involvement pre-scleroderma should be divided into two subsets: very early and early disease. Pre-scleroderma patients included in the Spanish Scleroderma Registry (RESCLE) Cohort were reclassified into subsets. Differences were evaluated and the risk of progression to definite systemic sclerosis was estimated. The characteristics of very early and early SSc patients were compared. A logistic regression model was used to determine the risk factors of progression. 1632 patients were included, 36 (2.2%) in the very early subset and 111 (6.8%) in the early subset. There were no differences in sex, age at disease onset, duration of Raynaud's phenomenon, antinuclear antibodies or capillaroscopic findings. Three (8.3%) very early SSc patients evolved to definite SSc, 2 (5.6%) of them meeting the ACR/EULAR 2013 criteria, unlike 31 (28%) early SSc patients, 20 (24%) of them meeting the criteria (p=0.034). Digestive involvement was an independent risk factor of progression (OR 17; 95% CI, 6.1-47.2). The classification of early forms of scleroderma identifies patients with different prognostic risk of progression. The evolution to definite SSc is more frequent in early than in very early SSc patients. Digestive involvement is a risk factor of progression. An active assessment of organ damage in preclinical stages allows a correct classification and risk stratification, with implications for monitoring and treatment. Copyright © 2017 Elsevier B.V.

    Exercise impairment is a common symptom of systemic sclerosis (SSc), a disorder which is frequently complicated by cardiopulmonary involvement. This study's aims were: (a) to define the prevalence and the potential causes of limited exercise capacity and (b) to study potential differences in clinical, radiological and functional characteristics and blood serology among SSc patients with exercise limitation of different etiology. Prospectively collected data on SSc patients who had conducted full lung function testing, blood serology, thorax high-resolution computed tomography, Doppler echocardiogram and a maximal cardiopulmonary exercise testing (CPET) were retrospectively analyzed. Using a CPET algorithm, patients were characterized as having normal or subnormal exercise capacity (N), respiratory limitation (RL), left ventricular dysfunction (LVD) or pulmonary vasculopathy (PV). Group comparisons were conducted using either one-way ANOVA or the Kruskal-Wallis test. A p value present in 32.1%, LVD in 25.6% and RL in 10.2%, while 32.1% of the patients constituted the N group. The presence of antisclero-70 antibodies, low anaerobic threshold and low peak exercise capacity measures could discriminate LVD from the other groups. Low end-tidal carbon dioxide pressure and its change from rest to anaerobic threshold could discriminate between the PV, LVD and N groups, while respiratory restriction along with ventilatory inefficiency indices could differentiate the RL group from the rest. The combined evaluation of CPET gas exchange patterns with baseline measurements could discriminate the causes of exercise limitation among SSc patients. © 2016 S. Karger AG, Basel.

    Full Text Available Abstract Background Previous reports on lymphocyte subpopulations in systemic sclerosis (SSc are conflicting. Therefore, we aimed to investigate the lymphocyte subsets in SSc patients who were not on immunosuppressive therapy. Methods Lymphocyte subsets were assessed in the peripheral blood of SSc patients (n = 29 and healthy controls (n = 29 using the four colour flow cytometry method. Correlation studies were also performed in order to assess the relationship between lymphocyte subsets and clinical parameters. Results The absolute count of lymphocytes (P = 0.0042, CD3+ (P = 0.0014, CD4+ (P = 0.0070, CD8+ (P = 0.021, and CD19+ cells (P = 0.024 was significantly decreased in SSc patients when compared to healthy controls. CD4+/CD8+ ratio and the absolute count of CD56+ cells observed in SSc patients did not significantly differ from controls (P = 0.165; P = 0.632, respectively. There was no substantial relationship between the lymphocyte subset levels and clinical features (i.e., SSc subtype, autoantibody profiles, organ involvement, except for a significant inverse correlation of CD19+ cells and the modified Rodnan skin score (r = -0.43, P = 0.020. Conclusion Our data support previous reports indicating that subsets of T lymphocytes as well as B lymphocytes play a role in the pathogenesis of SSc.

    To measure self-reported physical and mental functioning and associated clinical features at study entry in 3 ethnic groups with systemic sclerosis (SSc). Sixty Hispanic, 39 African American, and 104 Caucasian patients with recent-onset SSc ( fatigue scores > IBQ > clinical variables (hypertension, skin score, and percentage predicted DLCO). Scleroderma-HAQ scores had ethnic-specific associations with IBQ > AHI scores > most clinical and laboratory variables. Decreased mental component summary (MCS) scores associated with AHI > ISEL. Ethnic-specific immunogenetic variables HLA-DQB1*0202 (Caucasian) and HLA-DRB 1*11 (African American), and HLA-DQA1*0501 (Hispanic) also associated with MCS. Antinuclear autoantibodies, anti-topoisomerase I, and RNA polymerases I and III also demonstrated associations with functioning in African American and Hispanic groups. Clinical, psychosocial, and immunogenetic variables had ethnic-specific associations with perceived physical and mental functioning. Consideration of ethnic-specific psychological and behavioral support in designing more personalized, relevant therapeutic interventions for the patient may improve therapeutic efficacy in SSc.

    Progressive systemic sclerosis (PSS) may involve any portion of the gastrointestinal tract including the colon. Constipation is common in patients with PSS. Cisapride, a benzamide derivative, is a potentially useful agent in the treatment if chronic idiopathic constipation. The effect of cisapride on colonic transit was evaluated in 16 PSS patients by radionuclide colonic transit method. Static images were acquired at regular times, then the geometric center (GC) values were calculated. Each patient received cisapride orally three times a day for a week. The median GC at 4 hours was 0.351 in patients before treatment and 0.775 after treatment. The difference is significant with a p value of 0.026. The median GC at 24 hours was 1.957 in patients before treatment and significantly increased to 2.509 after treatment. The p value was 0.038. Clinically, twelve patients had symptoms of constipation and 8 of them showed improvement of the symptoms after administration of cisapride. The result showed acceleration in colonic transit in response to cisapride. We conclude that cisapride is effective in the treatment of constipation in patients with PSS

    OBJECTIVE To identify factors associated with oral hygiene practices in adults with systemic sclerosis (SSc) METHODS In this cross-sectional study, 178 dentate adults with SSc received an oral examination which included measurement of oral aperture, assessment of manual dexterity to perform oral hygiene, as well as completion of the Center of Epidemiological Studies Depression (CES-D) Scale, and an oral health-related questionnaire. RESULTS Multivariable logistic regression modeling showed male, minority and high CES-D scores (i.e., clinically significant symptoms of depression) were associated with less likelihood of participants brushing teeth at least twice daily, but the presence of self-reported dry mouth symptoms increased the likelihood of toothbrushing. Having a dental visit in the past 12 months, and use of an adapted flossing or interdental cleaning device were significantly associated with daily dental flossing; however, having difficulty flossing teeth reduced the likelihood of daily flossing. CONCLUSIONS Overall, demographic variables were strongly associated with toothbrushing frequency, whereas, flossing self-efficacy and barriers were strongly associated with dental flossing frequency in adults with SSc. The results suggest that dental health professionals should take mental health into consideration when educating patients with SSc to improve their oral hygiene, and consider making referrals for patients exhibiting suspected clinically significant depressive symptoms to mental health professionals for further evaluation and treatment. In addition, an appropriate adapted flossing or interdental cleaning device should be recommended to increase dental flossing practices in this patient population. PMID:24128049

    To describe, from the patient's point of view, the factors influencing the occupational trajectory of patients with systemic sclerosis (SSc). This was a qualitative study designed using grounded theory with constant comparison. Data were collected through semi-structured interviews with 14 patients who fulfilled the American College of Rheumatology or Leroy-Medsger criteria for SSc. Based on our interviews, we found that the occupational trajectory of patients with SSc is influenced by the continuous interplay between four groups of factors. The first group concerns the values patients attribute to work, including identity, normality, financial value, social contact, and structure. The meaning of these values and how they relate to each other underlies the desire to work. A second group of factors is those influencing the balance between daily life, work participation, and medical condition (e.g. job content, flexibility in organising work, and the willingness to ask for accommodations at work). The occupational trajectory is also influenced by external factors, including availability of support, know-ledge of the disease, pressure to work, contact with medical professionals, and existing regulations and the patient's knowledge about them. Finally, the occupational trajectory is influenced by personal factors, including socio-demographics, psychological assets, and disease- and work-related personal factors. The decisions patients with SSc take concerning work depend on an interplay between many factors and, especially, on the patients' personal interpretation of these factors. These need to be taken into account when helping patients with SSc determine their occupational trajectory.

    To determine the prognostic value of pulmonary function test (PFT) trends at 1 and 2 years in interstitial lung disease (ILD) associated with systemic sclerosis (SSc). The prognostic significance of PFT trends at 1 year (n = 162) and 2 years (n = 140) was examined against 15-year survival in patients with SSc-associated ILD. PFT trends, expressed as continuous change and as categorical change in separate analyses, were examined against mortality in univariate and multivariate models. SSc-associated ILD was defined at presentation as either limited lung fibrosis or extensive lung fibrosis, using the United Kingdom Raynaud's and Scleroderma Association severity staging system. One-year PFT trends were predictive of mortality only in patients with extensive lung fibrosis: categorical change in the forced vital capacity (FVC), alone or in combination with categorical change in the diffusing capacity for carbon monoxide (DLco), had greater prognostic significance than continuous change in the FVC or trends in other PFT variables. Taking into account both prognostic value and sensitivity to change, the optimal definition of progression for trial purposes was an FVC and DLco composite end point, consisting of either an FVC decline from baseline of ≥10% or an FVC decline of 5-9% in association with a DLco decline of ≥15%. At 2 years, gas transfer trends had the greatest prognostic significance, in the whole cohort and in those with limited lung fibrosis. However, in patients with extensive lung fibrosis, the above-defined FVC and DLco composite end point was the strongest prognostic determinant. Larger changes in the FVC:DLco ratio than in the carbon monoxide transfer coefficient were required to achieve prognostic significance. Based on linkages to long-term outcomes, these findings provide support for use of routine spirometry and gas transfer monitoring in patients with SSc-associated ILD, with further evaluation of a composite FVC and DLco end point

    Full Text Available BACKGROUND: Pulmonary complications are the most common cause of death and morbidity in systemic sclerosis (SSc. The forced oscillation technique (FOT offers a simple and detailed approach to investigate the mechanical properties of the respiratory system. We hypothesized that SSc may introduce changes in the resistive and reactive properties of the respiratory system, and that FOT may help the diagnosis of these abnormalities. METHODOLOGY/PRINCIPAL FINDINGS: We tested these hypotheses in controls (n = 30 and patients with abnormalities classified using spirometry (n = 52 and pulmonary volumes (n = 29. Resistive data were interpreted with the zero-intercept resistance (Ri and the slope of the resistance (S as a function of frequency. Reactance changes were evaluated by the mean reactance between 4 and 32 Hz (Xm and the dynamic compliance (Crs,dyn. The mechanical load was evaluated using the absolute value of the impedance in 4 Hz (Z4Hz. A compartmental model was used to obtain central (R and peripheral (Rp resistances, and alveolar compliance (C. The clinical usefulness was evaluated by investigating the area under the receiver operating characteristic curve (AUC. The presence of expiratory flow limitation (EFL was also evaluated. For the groups classified using spirometry, SSc resulted in increased values in Ri, R, Rp and Z4Hz (p0.90. In groups classified by pulmonary volume, SSc resulted in reductions in S, Xm, C and Crs,dyn (p0.80. It was also observed that EFL is not common in patients with SSc. CONCLUSIONS/SIGNIFICANCE: This study provides evidence that the respiratory resistance and reactance are changed in SSc. This analysis provides a useful description that is of particular significance for understanding respiratory pathophysiology and to ease the diagnosis of respiratory abnormalities in these patients.

    There is evidence for the benefits of exercise training in persons with multiple sclerosis (MS). However, these benefits have primarily been established in individuals with mild-to-moderate disability (i.e., Expanded Disability Status Scale [EDSS] scores 1.0-5.5), rather than among those with significant mobility impairment. Further, the approaches to exercise training that have been effective in persons with mild-to-moderate MS disability may not be physically accessible for individuals with mobility limitations. Therefore, there is a demand for an evidence-base on the benefits of physically accessible exercise training approaches for managing disability in people with MS with mobility impairment. To conduct a systematic review of the current literature pertaining to exercise training in individuals with multiple sclerosis (MS) with severe mobility disability. Four electronic databases (PubMed, EMBASE, OvidMEDLINE, and PsychINFO) were searched for relevant articles published up until October 2016. The review focused on English-language studies that examined the effect of exercise training in people with MS with severe mobility disability, characterized as the need for assistance in ambulation or EDSS score ≥ 6.0. The inclusion criteria involved full-text articles that: (i) included participants with a diagnosis of MS; (ii) included primarily participants with a reported EDSS score ≥ 6.0 and/or definitively described disability consistent with this level of neurological impairment; and (iii) implemented a prospective, structured exercise intervention. Data were analyzed using a descriptive approach and summarized by exercise training modality (conventional or adapted exercise training), and by outcome (disability, physical fitness, physical function, and symptoms and participation). Initially, 1164 articles were identified and after removal of duplicates, 530 articles remained. In total, 512 articles did not meet the inclusion criteria. 19 articles were

    To provide data on the economic burden and health-related quality of life (HRQoL) associated with systemic sclerosis (SSc) in France and to raise awareness of the repercussions of this disease for patients and caregivers and on the health and social care system. A cross-sectional study was carried out on 147 patients recruited through the Association des Sclérodermiques de France (ASF), the French association for SSc patients. Data on the patients' use of resources were obtained retrospectively from an online questionnaire and costs were estimated by a bottom-up approach. The HRQoL patients and caregivers was assessed with the five-level EURQol-5 Dimension (EQ-5D-5L) health questionnaire. The average annual cost of SSc was estimated at EUR 22,459 per patient. Direct healthcare costs amounted to EUR 8452, direct non-healthcare formal costs to EUR 1606, direct non-healthcare informal costs to EUR 1875, and indirect costs resulting from patients' absence from the labour market to EUR 10,526. The main contributors to SSc costs were hospitalizations and early retirement. Mean EQ-5D utility scores were 0.49 for patients and 0.66 for caregivers. Although SSc is a rare disease, its economic burden from a societal perspective is substantial and the consequences for HRQoL are significant for both patients and caregivers in France, underscoring the need to develop tailored policies targeted at improving patients' care and reducing the long-term impact of SSc.

    Objective Systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are related chronic autoimmune diseases of complex aetiology in which the interferon (IFN) pathway plays a key role. Recent studies have reported an association between IRF7 and SLE which confers a risk to autoantibody production. A study was undertaken to investigate whether the IRF7 genomic region is also involved in susceptibility to SSc and the main clinical features. Methods Two case-control sets of Caucasian origin from the USA and Spain, comprising a total of 2316 cases of SSc and 2347 healthy controls, were included in the study. Five single nucleotide polymorphisms (SNPs) in the PHRF1-IRF7-CDHR5 locus were genotyped using TaqMan allelic discrimination technology. A meta-analysis was performed to test the overall effect of these genetic variants on SSc. Results Four out of five analysed SNPs were Significantly associated with the presence of anticentromere autoantibodies (ACA) in the patients with SSc in the combined analysis (rs1131665: pFDR=6.14 × 10−4, OR=0.78; rs4963128: pFDR=6.14 × 10−4, OR=0.79; rs702966: pFDR=3.83 × 10−3, OR=0.82; and rs2246614: pFDR=3.83 × 10−3, OR=0.83). Significant p values were also obtained when the disease was tested globally; however, the statistical significance was lost when the ACA-positive patients were excluded from the study, suggesting that these associations rely on ACA positivity. Conditional logistic regression and allelic combination analyses suggested that the functional IRF7 SNP rs1131665 is the most likely causal variant. Conclusions The results show that variation in the IRF7 genomic region is associated with the presence of ACA in patients with SSc, supporting other evidence that this locus represents a common risk factor for autoantibody production in autoimmune diseases.

    Birth order has been valuable in revealing the role of environmental influences on the risk of developing certain diseases such as allergy and atopy. In addition, pregnancy has profound effects on the immune system such as short-term effects that permit fetal survival as well as longer-term effects that could influence late-onset diseases. In order to better evaluate these influences, we studied the association of birth order and gravidity/parity as risk factors for systemic sclerosis (SSc; scleroderma). Data regarding SSc cases and their unaffected sibling controls were obtained from the Scleroderma Family Registry and DNA Repository. The case-sibling design was used to minimize confounding due to differences in age, race, ethnicity, or calendar time. The gravidity/parity analysis was based on sibships with at least one SSc-affected and one unaffected sister. Birth order was examined in 974 sibships, comparing SSc cases (n = 987) with their unaffected siblings (n = 3,088). The risk of scleroderma increased with increasing birth order (odds ratio [OR] 1.25, 95% confidence interval [95% CI] 1.06-1.50 for birth order 2-5; OR 2.22, 95% CI 1.57-3.15 for birth order 6-9; and OR 3.53, 95% CI 1.68-7.45 for birth order 10-15). Gravidity/parity was analyzed in 168 sibships (256 unaffected sisters, 172 SSc cases). We found an association between a history of one or more pregnancies and SSc (OR 2.8). Birth order and pregnancy were independently associated with a higher risk of developing SSc. These findings suggest that immune development in early childhood and/or pregnancy-associated events, including but not limited to microchimerism, plays a role in SSc susceptibility.

    Vasculopathy is a key factor in the pathophysiology of systemic sclerosis (SSc) and the main cause for Raynaud phenomenon (RP), digital ulcers (DU), and/or pulmonary arterial hypertension (PAH). It is so far unknown how patients with SSc are treated with vasoactive agents in daily practice. To determine to which extent patients with SSc were treated with different vasoactive agents, we used data from the German Network for Systemic Scleroderma registry. The data of 3248 patients with SSc were analyzed. Patients were treated with vasoactive drugs in 61.1% of cases (1984/3248). Of these, 47.6% received calcium channel inhibitors, followed by 34.2% treated with angiotensin-converting enzyme (ACE) inhibitors, 21.1% treated with intravenous (IV) prostanoids, 10.1% with pentoxifylline, 8.8% with angiotensin 1 receptor antagonists (AT1RA), 8.7% with endothelin 1 receptor antagonists (ET1RA), 4.1% with phosphodiesterase type 5 (PDE5) inhibitors, and 5.3% with others. Patients with RP received vasoactive therapy in 63.3% of cases, with DU in 70.1%, and with PAH in 78.2% of cases. Logistic regression analysis revealed that patients with PAH were significantly more often treated with PDE5 inhibitors and ET1RA, and those with DU with ET1RA and IV prostanoids. In addition, 41.8% of patients were treated with ACE inhibitors and/or AT1RA. Patients registered after 2009 received significantly more often ET1RA, AT1RA, and IV prostanoids compared with patients registered prior to 2005. These data clearly indicate that many patients with SSc do not yet receive sufficient vasoactive therapy. Further, in recent years, a marked change of treatment regimens can be observed.

    Systemic sclerosis (SSc) is a rare and devastating disease affecting skin and internal organs. Familial aggregation of SSc and co-aggregation with other autoimmune diseases is rarely reported. We identified 23,658,577 beneficiaries registered with the National Health Insurance database in 2010, 1891 of whom had SSc. We identified 21,009,551 parent-child relationships and 17,168,340 full sibling pairs. The familial risks of SSc and other autoimmune diseases and familial transmission were estimated. The prevalence of SSc in the general population was 0.008 %. There are 3801 individuals had at least one first-degree relative with SSc, among them 3 people had SSc which was equivalent to a prevalence of 0.08 %. The adjusted relative risk (RR) (95 % CI) for SSc was 81.21 (11.40-579.72) for siblings of SSc patients. The familial transmission (genetic plus shared environmental contribution to total phenotypic variance of SSc) was 0.72. However, 84.1 % of patients were expected to be sporadic cases. The RR (95 % CI) in first-degree relatives of SSc patients was 2.64 (1.46-4.75) for rheumatoid arthritis, 6.51 (4.05-10.46) for systemic lupus erythematosus, 2.77 (1.04-7.35) for Sjögren's syndrome, 8.05 (2.03-31.92) for idiopathic inflammatory myositis, and 1.52 (1.15-2.01) for psoriasis. The risks of SSc and other autoimmune diseases are increased in relatives of people with SSc, and family factors explain over two-thirds of the phenotypic variance of the disease. These findings may be useful in counselling families of patients with SSc and for further genetic studies.

    Spinal muscular atrophy (SMA) and sporadic amyotrophic lateral sclerosis (SALS) are both motor neuron disorders. SMA results from the deletion of the survival motor neuron ( SMN ) 1 gene. High or low SMN1 copy number and the absence of SMN2 have been reported as risk factors for the development or severity of SALS. To investigate the role of SMN gene copy number in the onset and severity of SALS in Malians. We determined the SMN1 and SMN2 copy number in genomic DNA samples from 391 Malian adult volunteers, 120 Yoruba from Nigeria, 120 Luyha from Kenya and 74 U.S. Caucasians using a Taqman quantitative PCR assay. We evaluated the SALS risk based on the estimated SMA protein level using the Veldink formula ( SMN1 copy number + 0.2 ∗  SMN2 copy number). We also characterized the disease natural history in 15 ALS patients at the teaching hospital of Point G, Bamako, Mali. We found that 131 of 391 (33.5%) had an estimated SMN protein expression of ≤ 2.2; 60 out of 391 (15.3%) had an estimated SMN protein expression < 2 and would be at risk of ALS and the disease onset was as early as 16 years old. All 15 patients were male and some were physically handicapped within 1-2 years in the disease course. Because of the short survival time of our patients, family histories and sample DNA for testing were not done. However, our results show that sporadic ALS is of earlier onset and shorter survival time as compared to patients elsewhere. We plan to establish a network of neurologists and researchers for early screening of ALS.

    Pulmonary veno-occlusive disease (PVOD) is a rare cause of pulmonary arterial hypertension (PAH). Because of the similar clinical picture of dyspnea on exertion and signs of right heart failure, PVOD is difficult to distinguish from idiopathic PAH. However, the distinction is mandatory because PVOD has a worse prognosis and, more importantly, the administration of PAH specific therapy (vasodilators) can precipitate severe acute pulmonary oedema. We present a challenging case of PAH in a patient with systemic sclerosis in whom a marked decrease in functional capacity after the initiation of bosentan therapy led to the diagnosis of PVOD. Management of PVOD patients is challenging and referral for lung transplantation should be done at the moment of diagnosis.

    Raynaud's phenomenon (RP) is the commonest manifestation of systemic sclerosis (SSc). RP is an episodic phenomenon, not easily assessed in the clinic, leading to reliance on self-report. A thorough understanding of the patient experience of SSc-RP is essential to ensuring patient-reported outcome (PRO) instruments capture domains important to the target patient population. We report the findings of an international qualitative research study investigating the patient experience of SSc-RP. Focus groups (FGs) of SSc patients were conducted across 3 scleroderma centers in the US and UK, using a topic guide and a priori purposive sampling framework devised by qualitative researchers, SSc patients and SSc experts. FGs were audio recorded, transcribed, anonymised and analysed using inductive thematic analysis. FGs were conducted until thematic saturation was achieved. Forty SSc patients participated in 6 focus groups conducted in Bath (UK), New Orleans (US) and Pittsburgh (US). Seven major themes were identified that encapsulate the patient experience of SSc-RP: physical symptoms, emotional impact, triggers & exacerbating factors, constant vigilance & self-management, impact on daily life, uncertainty and adaptation. The inter-relationship of the 7 constituent themes can be arranged within a conceptual map of SSc-RP. We have explored the patient experience of SSc-RP in a diverse and representative SSc cohort and identified a complex interplay of experiences that result in significant impact. Work to develop a novel PRO instrument for assessing the severity and impact of SSc-RP, comprising domains/items grounded in the patient experiences of SSc-RP identified in this study is underway.

    To describe the prevalence and clinical correlates of endoscopic gastric antral vascular ectasia (GAVE; "watermelon stomach") in early diffuse systemic sclerosis (SSc). Subjects with early, diffuse SSc and evidence of specific internal organ involvement were considered for the Scleroderma: Cyclophosphamide Or Transplant (SCOT) trial. In the screening procedures, all patients underwent upper gastrointestinal endoscopy. Patients were then categorized into those with or without endoscopic evidence of GAVE. Demographic data, clinical disease characteristics, and autoantibody data were compared using Pearson chi-square or Student t tests. Twenty-three of 103 (22.3%) individuals were found to have GAVE on endoscopy. Although not statistically significant, anti-topoisomerase I (anti-Scl70) was detected less frequently among those with GAVE (18.8% vs 44.7%; p = 0.071). Similarly, anti-RNP antibodies (anti-U1 RNP) showed a trend to a negative association with GAVE (0 vs 18.4%; p = 0.066). There was no association between anti-RNA polymerase III and GAVE. Patients with GAVE had significantly more erythema or vascular ectasias in other parts of the stomach (26.1% vs 5.0%; p = 0.003). Endoscopic GAVE was present on screening in almost one-fourth of these highly selected patients with early and severe diffuse SSc. While anti-Scl70 and anti-U1 RNP trended toward a negative association with GAVE, there was no correlation between anti-RNA Pol III and GAVE. Patients with GAVE had a higher frequency of other gastric vascular ectasias outside the antrum, suggesting that GAVE may represent part of the spectrum of the vasculopathy in SSc.

    Amyotrophic lateral sclerosis (ALS) is a devastating and still untreatable motor neuron disease. Despite the molecular mechanisms underlying ALS pathogenesis that are still far from being understood, several studies have suggested the importance of a genetic contribution in both familial and sporadic forms of the disease. In addition to single-nucleotide polymorphisms (SNPs), which account for only a limited number of ALS cases, a consistent number of common and rare copy number variations (CNVs) have been associated to ALS. Most of the CNV-based association studies use a traditional candidate-gene approach that is inadequate for uncovering the genetic architectures of complex traits like ALS. The emergent paradigm of "systems biology" may offer a new perspective to better interpret the wide spectrum of CNVs in ALS, enabling the characterization of the complex network of gene products underlying ALS pathogenesis. In this review, we will explore the landscape of CNVs in ALS, putting specific emphasis on the functional impact of common CNV regions and genes consistently associated with increased risk of developing disease. In addition, we will discuss the potential contribution of multiple rare CNVs in ALS pathogenesis, focusing our attention on the complex mechanisms by which these proteins might impact, individually or in combination, the genetic susceptibility of ALS. The comprehensive detection and functional characterization of common and rare candidate risk CNVs in ALS susceptibility may bring new pieces into the intricate mosaic of ALS pathogenesis, providing interesting and important implications for a more precise molecular biomarker-assisted diagnosis and more effective and personalized treatments.

    Patients with systemic sclerosis (SSc) experience severe physical limitations and psychological morbidity, but their lived experience remains underrepresented and is reflected in the scarcity of evidence-based patient-centered interventions. We aimed to describe patients' perspectives of SSc to inform strategies to improve their care. Face-to-face semistructured interviews were conducted with 30 adult patients with limited cutaneous or diffuse cutaneous SSc in Australia. Transcripts were thematically analyzed using HyperRESEARCH software. Six themes were identified: bodily malfunction (restrictive pain, debilitating physical changes, pervasive exhaustion), deprivation of social function (loss of work and career, social isolation, threat to traditional roles, loss of intimacy), disintegration of identity (stigmatizing physical changes, disassociated self-image, extinguished hopes, alone and powerless, invisibility of illness), insecurity of care (unrecognized disease, ambiguity around diagnosis and cause, information insufficiency, resigning to treatment limitations, seeking reassurance, fear of progression), avoiding the sick role (evading thoughts of sickness, protecting family, favorable comparison), and perseverance and hope (positive stoicism, optimism about treatment and monitoring, taking control of own health, pursuing alternative treatments, transcending illness through support). SSc inflicts major bodily and social restrictions that crush patients' identity and self-image. Uncertainties about the cause, diagnosis, and prognosis can undermine confidence in care, leading to anxiety and therapeutic nihilism. Access to psychosocial care to support the patients' role and functioning capacity, as well as communication and education that explicitly address their concerns regarding management may potentially improve treatment satisfaction, self-efficacy, adherence, and outcomes in patients with SSc. © 2017, American College of Rheumatology.

    Full Text Available Objectives: Systemic sclerosis (SSc is characterized by altered microvascular structure and function. Nailfold videocapillaroscopy (NVC is the tool to evaluate capillary morphological structure and laser-Doppler Blood flowmetry (LDF can be used to estimate cutaneous blood flow of microvessels. The aim of this study was to investigate possible relationships between capillary morphology and blood flow in SSc. Methods: 27 SSc patients and 12 healthy subjects were enrolled. SSc microvascular involvement, as evaluated by NVC, was classified in three different patterns (“Early”, “Active”, “Late”. LDF analysis was performed at the II, III, IV, V hand fingers in both hands and both at cutaneous temperature and at 36°C. Statistical evaluation was carried out by non-parametric procedures. Results: Blood flow was found significantly lower in SSc patients when compared with healthy subjects (p<0.05. The heating of the probe to 36°C induced a significant increase in peripheral blood flow in all subjects compared to baseline (p <0.05, however, the amount of variation was significantly lower in patients with SSc, compared with healthy controls (p <0.05. The SSc patients with NVC “Late” pattern, showed lower values of peripheral blood flow than patients with NVC “Active” or “Early” patterns (p<0.05. Moreover, a negative correlation between the tissue perfusion score and the progression of the SSc microangiopathy was observed, as well as between the tissue perfusion and the duration of the Raynaud’s phenomenon (p <0.03. Conclusions: LDF can be employed to evaluate blood perfusion in the microvascular circulation in SSc patients. The blood flow changes observed with the LDF seem to correlate with the severity of microvascular damage in SSc as detected by NVC.

    Full Text Available Systemic sclerosis (SS, is an autoimmune connective tissue disease, the main clinical signs of which are due to disseminated microcirculatory disorders and fibrosis of the skin and viscera. Morphological examinations showed that 80% of patients with SS had renal changes, including those unassociated with rheumatic diseases. Whereas the prevalence of scleroderma renal crisis is now estimated to be 2–5%, there is considerably often an asymptomatic reduction in renal function (silent uremia, which is caused by multimorbidity and comorbidity. Its incidence in patients with SS may be as high as 55%. The presence of autoimmune connective tissue disease may be itself regarded as a risk factor of renal involvement. Fifteen-year survival is 72% in SS patients with no renal involvement and not more than 13% in those having renal involvement. In patients with SS, proteinuria is one of the most important independent risk factors for fatal outcomes (relative risk, 3.34, leaving far behind canonical risk factors, such as pulmonary hypertension, restrictive lung disease (a forced expiratory volume in one second to forced vital capacity ratio of <80%, respiratory failure (NYHA Class III and IV, as well as decreased lung diffuse capacity and high skin scores. The authors first propose a concept of the existence and pathogenesis of chronic scleroderma nephropathy, the basis for which is the vascular endothelial dysfunction phenomenon developing in different structural components of the nephron and kidney as a whole.

    Full Text Available Objective: Interstitial lung disease (ILD and pulmonary arterial hypertension (PAH are common complications of systemic sclerosis (SSc. Echocardiography evaluates PAH, and chest sonography detects even mild ILC as ultrasound lung comets (ULC, i.e. multiple comet-tails fanning out from the lung surface and originating from subpleural interlobular septa thickened by fibrosis. Aim: to assess ILaD and PAH by integrated cardiac and chest ultrasound in SSc. Methods: We enrolled 30 consecutive SSc patients (age= 54±13 years, 23 females in the Rheumatology Clinic of Pisa University. In all, we assessed systolic pulmonary arterial pressure (SPAP, from maximal velocity of tricuspid regurgitation flow, and ULC score with chest sonography (summing the number of ULC from each scanning space of anterior and posterior right and left chest, from second to fifth intercostal space. All patients underwent plasma assay for anti-topoisomerase antibodies (anti-Scl70, and antiicentromere associated with development of pulmonary involvement. Twenty-eight patients also underwent high resolution computed tomography, HRCT (from 0= no fibrosis to 3= honey combing. Results: ULC number - but not SPAP - was correlated to HRCT fibrosis and presence Scl-70 antibodies. ULC number was similar in localized or diffuse forms (16±20 vs 21±19, p=ns and was unrelated to SPAP (r=0.216, p=ns. Conclusions: Chest sonography assessment and ULC allow a complete, simple, radiation-free characterization of interstitial lung involvement in SSc - all in one setting and with the same instrument, same transducer and the same sonographer. In particular, ULC number is associated with HRCT evidence of lung fibrosis and presence of Scl-70 antibodies.

    Full Text Available Objective To detect the early preclinical alterations in cardiac autonomic control as well as altered cardiac function in systemic sclerosis (SSc patients and their relevance to the clinical features of the disease using noninvasive methods. Methods 30 SSc patients and 15 healthy controls matched for age and sex underwent clinical examination, serological analysis, and echocardiographic assessment including Doppler flow imaging to evaluate cardiac function, and 24-hour Holter monitoring analyzed for arrhythmia and heart rate variability (HRV in the time and frequency domains. Results The trans-mitral Doppler of early to atrial wave (E/A ratio was reversed in five patients (16.6% and the tricuspid E/A ratio was reversed in 10 patients (33.3%. Holter analysis for SSc patients revealed an increased prevalence of premature ventricular contractions (PVC ≥ 10/h ( P = 0.02, supra-ventricular tachycardias (SVTs ( P = 0.2, and total PVC count ( P = 0.0000. Highly significant ( P = 0.000 impairment in all HRV parameters was demonstrated in the SSc patients. Total skin thickness score (TSS, Raynaud's phenomenon and anti-scleroderma 70 (anti-SCL70 showed significant positive correlations with all arrhythmia parameters, while showing a significant negative correlation with the impaired ventricular diastolic function and various HRV parameters. No correlation was found between arrhythmia and HRV parameters and disease duration, disease type, or presence of anti-centromere antibodies. Conclusion Low heart rate variability, increased TSS and the presence of anti-SCL70 are correlated with preclinical cardiac involvement in SSc patients and may predict the likelihood of malignant arrhythmia and sudden cardiac death. Therefore, noninvasive HRV evaluation before clinical cardiac involvement in these patients might be beneficial when added to the clinical and laboratory assessments in detecting high-risk patients, and may allow for implementation of preventive

    Systemic sclerosis (SSc) is a chronic disease with microvascular damage. Nailfold capillaroscopy is a non-invasive method used for evaluating capillaries in SSc. Its findings could be related to the internal organ involvement and SSc course. In this study, we aimed to determine the association of the capillaroscopic patterns of nailfold capillaries with the disease subtypes of SSc, disease duration, and clinical manifestations. Seventy patients with SSc (15 cases with diffuse cutaneous SSc [DcSSc] and 55 patients with limited SSc [LcSSc]) were studied. The patients were classified into early and intermediate/late DcSSc and LcSSc regarding their disease duration. The capillaroscopy findings were classified into normal, 'early', 'active' and 'late' scleroderma patterns, and 'non-specific' changes. The association of the nailfold capillaroscopy changes and their components with clinical manifestations was also studied. We studied 15 DcSSc and 55 LcSSc patients. No association was found between the patterns of capillaroscopic changes and these subtypes. There were 8 early DcSSc, 7 intermediate/late DcSSc, 34 early LcSSc, and 21 intermediate/late LcSSc patients. In patients with LcSSc, the 'early' scleroderma pattern of capillaroscopy was associated with early disease based on duration. We found a direct association between some capillary components and some clinical findings. Also, some capillaroscopic components had an inverse association with some clinical manifestations. We found no association between the patterns of capillaroscopy and SSc subtypes; early scleroderma pattern of capillaroscopy was significantly associated with early LcSSc, compatible with the slower course of the disease in LcSSc. Subtle changes, capillary elongation, and capillary tortuosity had an inverse association with clinical manifestations and might be considered as good prognostic factors.

    We sought to assess employment status, risk factors for unemployment and the associations of unemployment with patients' health related quality of life (HRQoL). All patients enrolled in a systemic sclerosis (SSc) longitudinal cohort study, completed an employment questionnaire on enrolment. Clinical manifestations were defined based on presence at the time of enrolment. Summary statistics, chi-square tests, univariate and multivariable logistic regression were used to determine the associations of various risk factors with employment. Among 1587 SSc patients, 160 (20%) were unemployed at the time of cohort enrolment excluding retired patients. Of these, 63% had limited disease subtype. Mean (±SD) age at enrollment was 51.9 (±10.4) years; 13 years below the average retirement age in Australia. Mean (±SD) disease duration at recruitment was 11.1 (±10.9) years. Multivariable regression analysis revealed the presence of digital amputation (OR 3.9, 95%CI 1.7-9.1, p=0.002), diffuse disease subtype (OR 2.2, 95%CI 1.3-3.5, p-value=0.002), sicca symptoms (OR 2.7, 95%CI 1.6-4.4, punemployment. Unemployed patients had consistently poorer HRQoL scores in all domains (physical, emotional and mental health) of the SF-36 form than those who were employed. SSc is associated with substantial work disability and unemployment, which is in turn associated with poor quality of life. Raising awareness, identifying modifiable risk factors and implementing employment strategies and work place modifications are possible ways of reducing this burden.

    Improvement of skin fibrosis is part of the natural course of diffuse cutaneous systemic sclerosis (dcSSc). Recognising those patients most likely to improve could help tailoring clinical management and cohort enrichment for clinical trials. In this study, we aimed to identify predictors for improvement of skin fibrosis in patients with dcSSc. We performed a longitudinal analysis of the European Scleroderma Trials And Research (EUSTAR) registry including patients with dcSSc, fulfilling American College of Rheumatology criteria, baseline modified Rodnan skin score (mRSS) ≥7 and follow-up mRSS at 12±2 months. The primary outcome was skin improvement (decrease in mRSS of >5 points and ≥25%) at 1 year follow-up. A respective increase in mRSS was considered progression. Candidate predictors for skin improvement were selected by expert opinion and logistic regression with bootstrap validation was applied. From the 919 patients included, 218 (24%) improved and 95 (10%) progressed. Eleven candidate predictors for skin improvement were analysed. The final model identified high baseline mRSS and absence of tendon friction rubs as independent predictors of skin improvement. The baseline mRSS was the strongest predictor of skin improvement, independent of disease duration. An upper threshold between 18 and 25 performed best in enriching for progressors over regressors. Patients with advanced skin fibrosis at baseline and absence of tendon friction rubs are more likely to regress in the next year than patients with milder skin fibrosis. These evidence-based data can be implemented in clinical trial design to minimise the inclusion of patients who would regress under standard of care. Published by the BMJ Publishing Group Limited.

    We have recently described a novel population of natural regulatory T cells (T(reg)) that are characterized by the expression of HLA-G and may be found at sites of tissue inflammation (HLA-G(pos) T(reg)). Here we studied the role of these cells in multiple sclerosis (MS), a prototypic autoimmune inflammatory disorder of the central nervous system (CNS). Sixty-four patients with different types of MS, 9 patients with other neurological diseases, and 20 healthy donors were included in this study. Inflamed brain lesions from 5 additional untreated MS patients were examined. HLA-G(pos) T(reg) were analyzed in the cerebrospinal fluid (CSF) by flow cytometry and in inflammatory demyelinating lesions of MS brain specimens by immunohistochemistry. Functional capacity was accessed and transmigration was determined using an in vitro model of the human blood-brain barrier (BBB). HLA-G(pos) T(reg) were found enriched in the inflamed CSF of MS patients and in inflammatory demyelinating lesions of MS brain specimens. HLA-G(pos) T(reg) showed a strong propensity to transmigrate across BBB, which was vigorously driven by inflammatory chemokines, and associated with a gain of suppressive capacity upon transmigration. CSF-derived HLA-G(pos) T(reg) of MS patients represented a population of activated central memory activated T cells with an upregulated expression of inflammatory chemokine receptors and exhibiting full suppressive capacity. Unlike natural FoxP3-expressing T(reg), HLA-G(pos) T(reg) derived from peripheral blood were functionally unimpaired in MS. In MS, HLA-G(pos) T(reg) may serve to control potentially destructive immune responses directly at the sites of CNS inflammation and to counterbalance inflammation once specifically recruited to the CNS.

    To determine intra- and inter-observer reliability of widefield microscopy to measure nailfold capillary density in patients with systemic sclerosis (SSc). Five SSc patients were examined with a STEMV-8 Zeiss biomicroscope with 50x magnification. The nailfold of the second, third, fourth and fifth fingers of both hands of each patient were photographed twice by each of two observers, once in the morning and again in the afternoon (total of 32 pictures). Two raters reviewed the photographs to produce capillary density readings. Intra- and inter-rater reliability of the readings were computed using intra-class correlations (ICC). Additional analyses were undertaken to determine the impact of other sources of variability in the data, namely patient, finger, technician and time. Intra-and inter-rater reliability were substantial (ICC 0.72-0.84) when raters were reading the same photographs or photographs taken at the same time of day. Agreement was only fair between morning and afternoon density readings (ICC 0.30-0.37). Patients, individual fingers and technician accounted for a large part of the variability in the data (combined variance component of 7.69 out of the total 12.23). The coefficient of variation of widefield microscopy was 24%. Although intra- and inter-rater reliability of nailfold capillary density measurements using widefield microscopy are good, proper standardisation of the conditions under which capillaroscopy is done and better imaging of nailfold capillary abnormalities should be considered if nailfold capillary density is to be used as an outcome measure in multi-centre clinical trials in SSc.

    To identify factors associated with oral hygiene practices in adults with systemic sclerosis (SSc). In this cross-sectional study, 178 dentate adults with SSc received an oral examination which included measurement of oral aperture, assessment of manual dexterity to perform oral hygiene, as well as completion of the Center of Epidemiological Studies Depression (CES-D) Scale and an oral health-related questionnaire. Multivariable logistic regression modelling showed male, minority and high CES-D scores (i.e. clinically significant symptoms of depression) were associated with less likelihood of participants brushing teeth at least twice daily, but the presence of self-reported dry mouth symptoms increased the likelihood of toothbrushing. Having a dental visit in the past 12 months and use of an adapted flossing or interdental cleaning device were significantly associated with daily dental flossing; however, having difficulty flossing teeth reduced the likelihood of daily flossing. Overall, demographic variables were strongly associated with toothbrushing frequency, whereas flossing self-efficacy and barriers were strongly associated with dental flossing frequency in adults with SSc. The results suggest that dental health professionals should take mental health into consideration when educating patients with SSc to improve their oral hygiene and consider making referrals for patients exhibiting suspected clinically significant depressive symptoms to mental health professionals for further evaluation and treatment. In addition, an appropriate adapted flossing or interdental cleaning device should be recommended to increase dental flossing practices in this patient population. © 2013 John Wiley & Sons A/S.

  13. Hypogelsolinemia, a disorder of the extracellular actin scavenger system, in patients with multiple sclerosis

    Science.gov (United States)

    2010-01-01

    Background Extracellular gelsolin (GSN) and GC-globulin/Vitamin D-binding protein (DBP) appear to play an important role in clearing the actin from extracellular fluids and in modulating cellular responses to anionic bioactive lipids. In this study we hypothesized that cellular actin release and/or increase in bioactive lipids associated with multiple sclerosis (MS) development will translate into alteration of the actin scavenger system protein concentrations in blood and cerebrospinal fluid (CSF) of patients with MS. Methods We measured GSN and DBP concentrations in blood and CSF obtained from patients diagnosed with MS (n = 56) in comparison to a control group (n = 20) that includes patients diagnosed with conditions such as idiopathic cephalgia (n = 11), idiopathic (Bell's) facial nerve palsy (n = 7) and ischialgia due to discopathy (n = 2). GSN and DBP levels were measured by Western blot and ELISA, respectively. Results We found that the GSN concentration in the blood of the MS group (115 ± 78 μg/ml) was significantly lower (p < 0.001) compared to the control group (244 ± 96 μg/ml). In contrast, there was no statistically significant difference between blood DBP concentrations in patients with MS (310 ± 68 μg/ml) and the control group (314 ± 82 μg/ml). GSN and DBP concentrations in CSF also did not significantly differ between those two groups. Conclusions The decrease of GSN concentration in blood and CSF of MS subjects suggests that this protein may be involved in chronic inflammation associated with neurodegeneration. Additionally, the results presented here suggest the possible utility of GSN evaluation for diagnostic purposes. Reversing plasma GSN deficiency might represent a new strategy in MS treatment.

    Objective Systemic sclerosis (SSc) is a heterogeneous multifactorial disease dominated by progressive skin and internal organ fibrosis that is driven in part by Transforming Growth Factor-beta (TGF-β). An important downstream target of TGF-β is the Abelson (c-Abl) tyrosine kinase, and its inhibition by imatinib mesylate (Gleevec)attenuates fibrosis in mice. Here we examined the effect of c-Abl activation and blockade in explanted healthy control and SSc fibroblasts. Methods Skin biopsies and explanted fibroblasts from healthy subjects and patients with SSc were studied. Changes in genome-wide expression patterns in imatinib-treated control and SSc fibroblasts were analyzed by DNA microarray. Results Treatment of control fibroblasts with TGF-β resulted in activation of c-Abl and stimulation of fibrotic gene expression that was prevented by imatinib. Moreover, imatinib reduced basal collagen gene expression in SSc but not control fibroblasts. No significant differences in tissue levels of c-Abl and phospho-c-Abl were detected between SSc and control skin biopsies. In vitroimatinib induced dramatic changes in the expression of genes involved in fibrosis, cardiovascular disease, inflammation, and lipid and cholesterol metabolism. Remarkably, of the 587-imatinib-responsive genes, 91% showed significant change in SSc fibroblasts, but only 12% in control fibroblasts. Conclusion c-Abl plays a key role in fibrotic responses. Imatinib treatment results in dramatic changes in gene expression in SSc fibroblasts but has only modest effects in control fibroblasts. These data provide novel insights into the mechanisms underlying the antifibrotic effect of imatinib in SSc. PMID:22691216

    2011-03-01

    Full Text Available OBJECTIVE: Evoked potentials are used in the functional assessment of sensory and motor pathways. Conflicting results have been reported in different studies about the value of evoked potentials in demyelinating diseases. Over 80% of patients with multiple sclerosis present with a relapsing–remitting form of the disease. In this study we aimed to examine the value of each evoked potential to demonstrate the demyelinating lesions in a homogenous group of patients with relapsing remitting multiple sclerosis. We also aimed to examine the correlation between clinical status and evoked potential abnormalities. METHODS: Twenty patients with relapsing remitting multiple sclerosis and ten healthy volunteers were included in the study to evaluate the value of evoked potentials in a homogenous group. Visual, somatosensory and motor evoked potentials were measured and EDSS scores of the patients were calculated. RESULTS: Of 20 patients, 15 patients(75% had VEP abnormality, 14 patients (70% had MEP abnormality and 12 patients (60% had tibial SEP abnormality. All patients had at least one abnormal evoked potential measurement. The abnormality of evoked potentials also had a correlation with high EDSS scores. CONCLUSION: We concluded that evoked potentials, especially used in combination, are good markers to show the nervous damage in patients with multiple sclerosis

    Full Text Available Abstract Background Foot problems associated with Systemic Sclerosis (SSc/Scleroderma have been reported to be both common and disabling. There are only limited data describing specifically, the mechanical changes occurring in the foot in SSc. A pilot project conducted in preparation for this trial confirmed the previous reports of foot related impairment and reduced foot function in people with SSc and demonstrated a link to mechanical etiologies. To-date there have been no formal studies of interventions directed at the foot problems experienced by people with Systemic Sclerosis. The primary aim of this trial is to evaluate whether foot pain and foot-related health status in people with Systemic Sclerosis can be improved through the provision of a simple pressure-relieving insole. Methods The proposed trial is a pragmatic, multicenter, randomised controlled clinical trial following a completed pilot study. In four participating centres, 140 consenting patients with SSc and plantar foot pain will be randomised to receive either a commercially available pressure relieving and thermally insulating insole, or a sham insole with no cushioning or thermal properties. The primary end point is a reduction in pain measured using the Foot Function Index Pain subscale, 12 weeks after the start of intervention. Participants will complete the primary outcome measure (Foot Function Index pain sub-scale prior to randomisation and at 12 weeks post randomisation. Secondary outcomes include participant reported pain and disability as derived from the Manchester Foot Pain and Disability Questionnaire and plantar pressures with and without the insoles in situ. Discussion This trial protocol proposes a rigorous and potentially significant evaluation of a simple and readily provided therapeutic approach which, if effective, could be of a great benefit for this group of patients.

    Erectile dysfunction (ED) prevalence in male systemic sclerosis (SSc) is high and its pathogenesis is unclear. The aim of the study is to assess correlation between Doppler ultrasound indices of penis and kidneys or digital arteries in male systemic sclerosis. Fourteen men with systemic sclerosis were enrolled in this study. Erectile function was investigated by the International Index of Erectile Function-5. Peak systolic velocity, end diastolic velocity, resistive index, pulsative index, and systolic/diastolic ratio were measured on the cavernous arteries at the peno-scrotal junction in the flaccid state, on the interlobar artery of both kidneys and all ten proper palmar digital arteries. Ten (71 percent) patients have an International Index of Erectile Function-5 less than 21. Reduction of penis peak systolic velocity was observed in all SSc subjects. Doppler indices of cavernous arteries correlate with the International Index of Erectile Function-5. The renal and digital arteries resistive index demonstrated a good correlation (p less than 0.0001) with International Index of Erectile Function-5. A positive correlation exists between penis and kidney arteries Doppler indices: end diastolic velocity (p less than 0.05, r=0.54), resistive index (p less than 0.0001, r=0.90), systolic/diastolic ratio (p less than 0.01, r=0.69).

    During the past decades, better understanding of relapsing-remitting multiple sclerosis disease mechanisms have led to the development of several disease-modifying therapies, reducing relapse rates and severity, through immune system modulation or suppression. In contrast, current therapeutic options for progressive multiple sclerosis remain comparatively disappointing and challenging. One possible explanation is a lack of understanding of pathogenic mechanisms driving progressive multiple sclerosis. Furthermore, diagnosis is usually retrospective, based on history of gradual neurological worsening with or without occasional relapses, minor remissions or plateaus. In addition, imaging methods as well as biomarkers are not well established. Magnetic resonance imaging studies in progressive multiple sclerosis show decreased blood-brain barrier permeability, probably reflecting compartmentalization of inflammation behind a relatively intact blood-brain barrier. Interestingly, a spectrum of inflammatory cell types infiltrates the leptomeninges during subpial cortical demyelination. Indeed, recent magnetic resonance imaging studies show leptomeningeal contrast enhancement in subjects with progressive multiple sclerosis, possibly representing an in vivo marker of inflammation associated to subpial demyelination. Treatments for progressive disease depend on underlying mechanisms causing central nervous system damage. Immunity sheltered behind an intact blood-brain barrier, energy failure, and membrane channel dysfunction may be key processes in progressive disease. Interfering with these mechanisms may provide neuroprotection and prevent disability progression, while potentially restoring activity and conduction along damaged axons by repairing myelin. Although most previous clinical trials in progressive multiple sclerosis have yielded disappointing results, important lessons have been learnt, improving the design of novel ones. This review discusses mechanisms involved

    Recently KAERI has developed the severe accident management guidance to establish the Korea standard severe accident management system. On the other hand the PC-based severe accident training simulator SATS has been developed, which uses the MELCOR code as the simulation engine. The simulator SATS graphically displays and simulates the severe accidents with interactive user commands. Especially the control capability of SATS could make a severe accident training course more interesting and effective. In this paper we will describe the development and functions of the electrical guidance module, HyperKAMG, and the SATS-HyperKAMG linkage system designed for a totally integrated and automated severe accident training.

    Pauling et al highlight some of the limitations of using the Raynaud's Condition Score (RCS) in clinical trials of Raynaud's phenomenon and the need for better patient reported outcome measures. They have explored this in a survey of patients with systemic sclerosis who completed the RCS and although the number of cases in the survey is small, and possibly not representative of a clinical trial population, the points raised are interesting.We acknowledge the difficulties of undertaking clinical trials in Raynaud's phenomenon.

    Full Text Available Introduction: Cutaneous sclerosis can lead to important mobility impairment. Ultraviolet (UV A1 phototherapy may improve skin sclerosis, although most of the studies have been with Caucasian patients. Material and Methods: A 44-year-old patient, Fitzpatrick skin type VI, was being followed up with the diagnosis of diffuse cutaneous systemic sclerosis. He had significant mobility impairment, especially of the right hand and arm. In 2015 he started UVA1 phototherapy daily, Monday until Friday (Waldmann® 7001 UVA cabin equipped with 40 Philips TL/10R lamps − spectral irradiation between 340 and 400 nm. The initial dose was 10 J/cm2, rapidly increased up to a steady dose of 35 J/cm2. Results: After 40 sessions of UVA1, active fingers flexion and abduction of the right arm significantly improved and the modified Rodnan skin score changed from 26 to 11. Conclusion: The modified Rodnan skin score is a practical and useful tool during the follow-up of patients with systemic sclerosis. UVA1 phototherapy improves cutaneous sclerosis, and the related mobility impairment, and a dose of 35 J/cm2 is effective, even in higher phototypes, having a good safety profile.

    Full Text Available Background: Systemic sclerosis (SSc is a multisystem connective tissue disorder of uncertain etiology. The clinical picture is frequently dominated by prominent cutaneous manifestations that have diagnostic and prognostic significance. The objective of the present study was to find out the demographic profile and the relative frequencies and characteristics of different mucocutaneous features of SSc in a group of patients from eastern India. In addition, we sought to compare the frequency and pattern of the findings in the limited versus the diffuse variety of the disease. Materials and Methods:This was a cross-sectional, clinical observational study. Consecutive patients of SSc attending the dermatology O.P.D. of a tertiary care hospital of eastern India over 3 years were enrolled to the present study. Results:A total of 46 patients (41 females and 5 males; mean age 29.6±12.3 years of SSc were evaluated. Among mucocutaneous manifestations Raynaud′s phenomenon was present in 39 (84.8% patients. Other cutaneous features included dyspigmentation (40, 86.9%, sclerodactyly (38, 82.6%, inability to open the mouth (38,82.6%, mat-like telangiectasia (11,23.1%, fingertip ulceration and scarring (29,63%, cutaneous calcinosis (1,2.2%, digital gangrene in (2,4.3%, generalized pruritus (4,8.7%, cutaneous small vessel vasculitis (2,4.3%, chronic urticaria (2,4.3%, flexion contractures of the fingers (13,28.3%, and amputation of the digits (3,6.5%.

    Objectives The rarity of early diffuse cutaneous systemic sclerosis (dcSSc) makes randomised controlled trials very difficult. We aimed to use an observational approach to compare effectiveness of currently used treatment approaches. Methods This was a prospective, observational cohort study of early dcSSc (within three years of onset of skin thickening). Clinicians selected one of four protocols for each patient: methotrexate, mycophenolate mofetil (MMF), cyclophosphamide or ‘no immunosuppressant’. Patients were assessed three-monthly for up to 24 months. The primary outcome was the change in modified Rodnan skin score (mRSS). Confounding by indication at baseline was accounted for using inverse probability of treatment (IPT) weights. As a secondary outcome, an IPT-weighted Cox model was used to test for differences in survival. Results Of 326 patients recruited from 50 centres, 65 were prescribed methotrexate, 118 MMF, 87 cyclophosphamide and 56 no immunosuppressant. 276 (84.7%) patients completed 12 and 234 (71.7%) 24 months follow-up (or reached last visit date). There were statistically significant reductions in mRSS at 12 months in all groups: −4.0 (−5.2 to −2.7) units for methotrexate, −4.1 (−5.3 to −2.9) for MMF, −3.3 (−4.9 to −1.7) for cyclophosphamide and −2.2 (−4.0 to −0.3) for no immunosuppressant (p value for between-group differences=0.346). There were no statistically significant differences in survival between protocols before (p=0.389) or after weighting (p=0.440), but survival was poorest in the no immunosuppressant group (84.0%) at 24 months. Conclusions These findings may support using immunosuppressants for early dcSSc but suggest that overall benefit is modest over 12 months and that better treatments are needed.

    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. To define the clinical differences between SSc, positive versus negative, for ATA. 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. 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). 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. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    pathogenesis of SSc. Heart fibrosis is one of the most important prognostic factors in SSc patients. So, the aim of our study was to examine cardiovascular dysfunction in SSc patients and its correlation with serum levels of vascular endothelial growth factor (VEGF, endostatin, and tissue inhibitor of metalloproteinase 2 (TIMP2. The study group comprised 34 patients (19 with limited scleroderma (lSSc and 15 with diffuse scleroderma (dSSc. The control group consisted of 20 healthy persons, age and sex matched. Internal organ involvement was assessed on the basis of specialist procedures. Serum VEGF, endostatin, and TIMP2 levels were evaluated by ELISA. We found cardiovascular changes in 15 patients with SSc (8 with lSSc and 7 with dSSc. The observed symptoms were of different characters and also coexisted with each other. Higher endostatin serum levels in all systemic sclerosis patients in comparison to the control group were demonstrated (P<.05. Also higher serum levels of endostatin and TIMP2 were observed in patients with cardiovascular changes in comparison to the patients without such changes (P<.05. The obtained results support the notion that angiogenesis and fibrosis disturbances may play an important role in SSc. Evaluation of endostatin and TIMP2 serum levels seems to be one of the noninvasive, helpful examinations of heart involvement in the course of systemic sclerosis.

    Objective: To compare the accuracy of high-resolution computed tomography (HRCT) with chest radiography in the diagnosis of interstitial lung disease in systemic sclerosis (SSc). Materials And Methods: HRCT scans and chest radiographs in postero-anterior and lateral views were performed in 34 patients with systemic sclerosis, according to the American College of Rheumatology preliminary criteria for the diagnosis of SSc. The prevalence of radiological findings suggestive of interstitial lung disease in SSc seen on both imaging methods was compared. Results: Interstitial disease was observed on HRCT images of 31 patients (91%) and in the chest radiographs of 16 patients (47%). The most frequent findings observed on HRCT were septal lines (74%), honeycombing (56%) and parenchymal bands (26%). Chest radiographs showed reticular areas of attenuation in 11 patients (32%) and parenchymal distortion in 12% of the patients. In 18 patients (53%) with normal chest radiographs HRCT showed septal lines in 55%, ground glass in 44%, honeycombing in 38.5% and cysts in 33%. Conclusion: HRCT is more sensitive than chest radiography in the evaluation of incipient interstitial lung involvement in patients with SSc and can provide a justification for immunosuppressive therapy in patients with early disease.

    In patients with systemic sclerosis (SSc), sexual function is somewhat impaired. Our aim was to evaluate sexual function in women with SSc in comparison to controls, and to investigate the association with sociodemographic and disease characteristics, and physical and psychological variables. Forty-six women with SSc and 46 healthy women were assessed for sociodemographic characteristics and gynecological development and administered the Female Sexual Function Index (FSFI), Medical Outcomes Study Short Form-36 (SF-36), Health Assessment Questionnaire (HAQ), Hospital Anxiety and Depression Scale (HADS), Rosenberg Self-Esteem Scale, Coping Orientation to Problems Experienced-New Italian Version, and Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Patients were also assessed for disease duration and subset, Female Sexual Function in SSc, Hand Mobility in Scleroderma test (HAMIS), Cochin Hand Functional Disability Scale, Mouth Handicap in Systemic Sclerosis Scale (MHISS), Disability Sexual and Body Esteem Scale (PDSBE); and fist closure, hand opening, and mouth opening. In patients with SSc, only FSFI desire subscale score was significantly lower (p = 0.035) versus controls. Total FSFI score, similar to controls, was related with Medical Outcomes Study Short Form-36 mental component, HAQ (p = 0.022), MHISS (p = 0.038), and HAMIS (p = 0.037). In SSc, the main factors independently associated with sexual functioning were vaginal dryness [regression coefficient (B) = -0.72; p psychological concerns. Thus it should be included in patient evaluations and assessed in daily clinical practice.

    we aimed to study systemic sclerosis patients in order to assess osteoprotegerin/Receptor activator of nuclear factor-kB ligand (OPG/RANKL) system and find the relation of these biomarkers with the clinical features of the disease, the carotid intima thickness, markers of inflammation, lipid profile, and other laboratory characteristics. both the level of (RANKL), (OPG) in sera of participants, in 30 (SSc) patients and the atherosclerotic changes affecting the common carotid artery were measured and, were compared to 30 healthy controls matched for age and sex. All participants were assessed clinically and subjected to the Revised Medsger SSc severity scale and underwent carotid Doppler ultrasound examination. OPG, RANKL, and RANKL/OPG were 1.9 ± 0.4 ng/ml, 24.3 ± 17.25 ng/ml, and 13.5 ±9.8 versus 0.77 ± 0.25 ng/ml, 7.13 ± 3.02 ng/ml, and 9.6 ± 3.1 in the SSc patients and the controls with significance (P = 0.001, P = 0.001, P = 0.045) respectively. The OPG- RANKL axis in the SSc patients correlated significantly with carotid intima thickness, arthritis, arthralgia, inflammatory markers, Medsger joint, Medsger vascular, Medsger skin, and dyslipidemia. In cardiovascular risks, OPG serum level might increase as a preventive compensatory mechanism to neutralize the RANKL level increment. The determination of the OPG-RANKL system is a diagnostic indicator for the intensity of vascular calcification and atherosclerosis in SSc patients.

  18. Intrinsic Deregulation of Vascular Smooth Muscle and Myofibroblast Differentiation in Mesenchymal Stromal Cells from Patients with Systemic Sclerosis.

    Björn Hegner

    Full Text Available Obliterative vasculopathy and fibrosis are hallmarks of systemic sclerosis (SSc, a severe systemic autoimmune disease. Bone marrow-derived mesenchymal stromal cells (MSCs from SSc patients may harbor disease-specific abnormalities. We hypothesized disturbed vascular smooth muscle cell (VSMC differentiation with increased propensity towards myofibroblast differentiation in response to SSc-microenvironment defining growth factors and determined responsible mechanisms.We studied responses of multipotent MSCs from SSc-patients (SSc-MSCs and healthy controls (H-MSCs to long-term exposure to CTGF, b-FGF, PDGF-BB or TGF-β1. Differentiation towards VSMC and myofibroblast lineages was analyzed on phenotypic, biochemical, and functional levels. Intracellular signaling studies included analysis of TGF-β receptor regulation, SMAD, AKT, ERK1/2 and autocrine loops.VSMC differentiation towards both, contractile and synthetic VSMC phenotypes in response to CTGF and b-FGF was disturbed in SSc-MSCs. H-MSCs and SSc-MSCs responded equally to PDGF-BB with prototypic fibroblastic differentiation. TGF-β1 initiated myofibroblast differentiation in both cell types, yet with striking phenotypic and functional differences: In relation to H-MSC-derived myofibroblasts induced by TGF-β1, those obtained from SSc-MSCs expressed more contractile proteins, migrated towards TGF-β1, had low proliferative capacity, and secreted higher amounts of collagen paralleled by reduced MMP expression. Higher levels of TGF-β receptor 1 and enhanced canonical and noncanonical TGF-β signaling in SSc-MSCs accompanied aberrant differentiation response of SSc-MSCs in comparison to H-MSCs.Deregulated VSMC differentiation with a shift towards myofibroblast differentiation expands the concept of disturbed endogenous regenerative capacity of MSCs from SSc patients. Disease related intrinsic hyperresponsiveness to TGF-β1 with increased collagen production may represent one responsible mechanism

    Full Text Available Abstract Background Case management has been suggested as an innovative strategy that facilitates the improvement of a patient's quality of life, reduction of hospital length of stay, optimization of self-care and improvement of satisfaction of patients and professionals involved. However, there is little evidence about the effectiveness of the patient advocacy case management model in clinical practice. Therefore, the objective of our study was to examine the effects of the Dutch patient advocacy case management model for severely disabled Multiple Sclerosis (MS patients and their caregivers compared to usual care. Methods/design In this randomized controlled trial the effectiveness of casemanagement on quality of life of patients and their caregivers, quality of care, service use and economic aspects were evaluated. The primary outcomes of this study were quality of life of MS-patients and caregiver burden of caregivers. Furthermore, we examined quality of life of caregivers, quality of care, service use and costs. Discussion This is a unique trial in which we examined the effectiveness of case management from a broad perspective. We meticulously prepared this study and applied important features and created important conditions for both intervention and research protocol to increase the likelihood of finding evidence for the effectiveness of patient advocacy case management. Concerning the intervention we anticipated to five important conditions: 1 the contrast between the case management intervention compared to the usual care seems to be large enough to detect intervention effects; 2 we included patients with complex care situations and/or were at risk for critical situations; 3 the case managers were familiar with disease specific health-problems and a broad spectrum of solutions; 4 case managers were competent and authorized to perform a medical neurological examination and worked closely with neurologists specialized in MS; and 5 the

    To identify the type of support and assistance that patients with multiple sclerosis need in order to cope with the loss of functionality, and to show how gender affects the perception of these needs. Interpretative-phenomenological qualitative study. Granada (Spain). Year: 2014. Intentional sample: 30 patients and 20 family caregivers. Data were gathered from 26 interviews and 4 focus groups. The data were coded and analysed with the NVivo programme. The multiple sclerosis patients and family caregivers had different perceptions of the loss of capacity to undertake activities of daily living. Being able to self care was considered the last vestige of autonomy. The women with multiple sclerosis tried to take on the responsibility of housework, but the male caregivers became gradually involved in these tasks. Gender roles were redefined with respect to housekeeping. The multiple sclerosis patients showed a need for emotional support. Some of the men had abandoned the stereotype of the strong male as a result of the decline in their health. Adaptations in the home took place without planning them in advance. The use of mobility devices started on an occasional basis. A fear of stigma was an obstacle for regular use of assistive technology. Health care for people with multiple sclerosis should include family caregivers. Gender influences the perception that caregivers and patients have of the assistance they require to maximise their quality of life. This flags up several intervention areas for the follow-up and long-term care of these patients by the healthcare system. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

    .The objectives of this article are to review aspects described in the literature on macrovasculature onset in systemic sclerosis and to assess occurrence and distribution of macrovascular alterations in patients with systemic sclerosis using Doppler ultrasound and ankle-brachial index. In addition, the article evaluates the association of these findings with demographic characteristics, clinical form, clinical course of the disease, Raynauds phenomenon, digital changes, limb ulcers, reabsorption of phalanges, amputation, and risk factors and antecedents of atheromatous disease. A prospective, case series study of 20 patients was performed. The sample was comprised of 19 women, with a mean age of 46.30 years. All patients had objective Raynauds phenomenon, 85% were diffuse, 55% had digital pulp changes, 15% current limb ulcer, 25% reabsorption of phalange, no amputations, and 70% presented one to four risk factors. Studies were performed by color Doppler ultrasound of the aortic and carotid arteries and lower and upper limb arteries to assess thickening of the intima-media complex, presence of plaques and aneurysms. Ankle-brachial index was also performed in lower limb arteries. Ankle-brachial index was normal in all patients, but 12 (60% had macrovascular disease assessed by Doppler ultrasound, nine (45% of these in the aorta, six (30% in the carotid arteries, one (5% in the upper limb arteries, and seven (35% in lower limb arteries. There was an association between macrovascular disease and digital pulp changes (p = 0.0045. Macrovascular disease was identified in 60% of the patients via Doppler ultrasound, but not via ankle-brachial index, which resulted normal in all patients. There was a significant association between macrovascular disease and current digital pulp changes, which did not occur with the other variables.

    Discrepancies in illness representations between patients and physicians result in treatment difficulties, decreased well-being of patients and misunderstandings and disrupted communication. Hence, the objective of this study was to compare illness perceptions of individual patients with systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), their rheumatologists and their general practitioners (GPs) and explore potential differences. This study has a cross-sectional design. Patients with SLE and SSc, who were followed at the rheumatology department of the University Hospitals Leuven (Belgium), completed the revised Illness Perception Questionnaire which measures patients' perceptions of their condition and captures nine dimensions. Physicians completed the Revised Illness Perception Questionnaire for Healthcare Professionals which consists of seven dimensions and measures perceptions of the healthcare professional regarding the disease of their patients. Intraclass correlation was performed to examine relationships between pairs of respondents; Cohen's d was used for estimating the magnitude of the difference. Questionnaires were sent to 284 patients of whom 241 (113 SSc and 128 SLE patients) were included. Five rheumatologists and 160 GPs participated. For both diseases, positive correlations were found for 'consequences', 'illness coherence' and 'emotional representations' among patients, rheumatologists and GPs. GPs scored higher on the 'consequences' of these diseases for the patient (d=0.71 for SLE; d=0.80 for SSc). Differences between rheumatologists and GPs were small for SSc and moderate to large for 'consequences' (d=0.56) and 'timeline acute/chronic' (d=0.95) in SLE with higher scores for GPs. For both diseases and among the three groups, significant correlations are detected for the dimensions 'consequences', 'illness coherence' and 'emotional representations'. Differences between rheumatologists and GPs were mainly detected in the case of SLE

    Full Text Available Human leukocyte antigen (HLA polymorphism studies in Systemic Sclerosis (SSc have yielded variable results. These studies need to consider the genetic admixture of the studied population. Here we used our previously reported definition of genetic admixture of Mexicans using HLA class I and II DNA blocks to map genetic susceptibility to develop SSc and its complications.We included 159 patients from a cohort of Mexican Mestizo SSc patients. We performed clinical evaluation, obtained SSc-associated antibodies, and determined HLA class I and class II alleles using sequence-based, high-resolution techniques to evaluate the contribution of these genes to SSc susceptibility, their correlation with the clinical and autoantibody profile and the prevalence of Amerindian, Caucasian and African alleles, blocks and haplotypes in this population.Our study revealed that class I block HLA-C*12:03-B*18:01 was important to map susceptibility to diffuse cutaneous (dc SSc, HLA-C*07:01-B*08:01 block to map the susceptibility role of HLA-B*08:01 to develop SSc, and the C*07:02-B*39:05 and C*07:02-B*39:06 blocks to map the protective role of C*07:02 in SSc. We also confirmed previous associations of HLA-DRB1*11:04 and -DRB1*01 to susceptibility to develop SSc. Importantly, we mapped the protective role of DQB1*03:01 using three Amerindian blocks. We also found a significant association for the presence of anti-Topoisomerase I antibody with HLA-DQB1*04:02, present in an Amerindian block (DRB1*08:02-DQB1*04:02, and we found several alleles associated to internal organ damage. The admixture estimations revealed a lower proportion of the Amerindian genetic component among SSc patients.This is the first report of the diversity of HLA class I and II alleles and haplotypes Mexican patients with SSc. Our findings suggest that HLA class I and class II genes contribute to the protection and susceptibility to develop SSc and its different clinical presentations as well as

    Full Text Available Foi feita análise e revisão de estudos populacionais de associação entre antígenos HLA e a esclerose múltipla (EM. Há evidências de que os genes HLA, principalmente os de classe II, das sub-regiões DR e DQ possam estar envolvidos. O haplótipo DRB1*1501.DQA1*0102.DQB1*0602 referente ao fenótipo DR2.Dw2.DQ6 foi encontrado em associação positiva em vários estudos realizados em populações caucasóides. O desequilíbrio de ligação entre os genes DR e DQ dificulta o reconhecimento da contribuição individual de cada alelo. A heterogeneidade de critérios diagnósticos da EM constitui importante fator metodológico que dificulta a comparação entre os diversos estudos. A padronização dos critérios diagnósticos e dos métodos laboratoriais empregados, assim como a análise individual de grupos de pacientes com formas clínicas diferentes, são medidas que provavelmente permitirão avaliação mais precisa dos fatores genéticos envolvidos no desenvolvimento da EM.Review of studies about HLA antigens and multiple sclerosis (MS. The HLA system, in special class II antigens, subregions DR and DQ, is probably involved in the immunopathogenesis of MS. Haplotype DRB1*1501.DQA1*0102.DQB1*0602, corresponding to phenotype DR2.Dw2.DQ6, is positively associated with MS in several caucasoid populations. Clinical heterogeneity of MS, as well as different diagnostic criteria adopted by investigators are potential sources of confusion and may lead to discrepant results. A better standardization of clinical and laboratorial methodology, appropriate subdivision of patients with different clinical forms of MS, may allow a more accurate evaluation of the role of genetic factors in the pathogenesis of MS.

    2009-10-01

    The neurobiological basis of attention-deficit hyperactivity disorder (ADHD) in tuberous sclerosis complex is still largely unknown. Cortical tubers may disrupt several brain networks that control different types of attention. Frontal lobe dysfunction due to seizures or epileptiform electroencephalographic discharges may perturb the development of brain systems that underpin attentional and hyperactive functions during a critical early stage of brain maturation. Comorbidity of attention-deficit hyperactivity disorder (ADHD) with mental retardation and autism spectrum disorders is frequent in children with tuberous sclerosis. Attention-deficit hyperactivity disorder (ADHD) may also reflect a direct effect of the abnormal genetic program. Treatment of children with tuberous sclerosis complex with combined symptoms of attention-deficit hyperactivity disorder (ADHD) and epilepsy may represent a challenge for clinicians, because antiepileptic therapy and drugs used to treat attention-deficit hyperactivity disorder (ADHD) may aggravate the clinical picture of each other.

    Full Text Available Multiple sclerosis is a chronic demyelinating disease of a central nervous system. Neuropsychiatric symptoms are common in multiple sclerosis and bipolar disorder is one of the most common psychiatric disorders that coexist with multiple sclerosis. Manic episodes may be the first presenting symptom of multiple sclerosis as comorbid pathology or as an adverse effect of pharmacotherapies used in multiple sclerosis. The comorbidity of bipolar disorder and multiple sclerosis is well-proven but its etiology is not known and investigated accurately. Recent studies support a common genetic susceptibility. Management of bipolar disorder in multiple sclerosis is based on evidence provided by case reports and treatment should be individualized. In this report, the association between bipolar disorder and multiple sclerosis, epidemiology, ethiology and treatment is discussed through a case had diagnosed as multiple sclerosis and had a manic episode with psychotic features.

    Some physically-disabled people with neuromuscular diseases such as amyotrophic lateral sclerosis, multiple sclerosis, muscular dystrophy, or other conditions that hinder their ability to write, type, and speak, require an assistive tool for purposes of augmentative and alternative communication in their daily lives. In this paper, we designed and implemented a wireless environmental control system using Morse code as an adapted access communication tool. The proposed system includes four parts: input-control module; recognition module; wireless-control module; and electronic-equipment-control module. The signals are transmitted using adopted radio frequencies, which permits long distance transmission without space limitation. Experimental results revealed that three participants with physical handicaps were able to gain access to electronic facilities after two months' practice with the new system.

    Translation, transculturation and validity of the self-administered questionnaire for functionality (Systemic Sclerosis Questionnaires [SySQ]) for use in Spanish patients with systemic sclerosis and its relationship to the severity of the disease and to quality of life. We conducted an observational analytical study to perform a cross-cultural validation of the self-administered questionnaire on functionality in scleroderma. The validity of the form and content was evaluated by an expert panel. The method included: a) adaptation into Spanish of the construct for translation and back translation, and transculturation; b) internal consistency with the SySQ (Cronbach's alpha), and c) reproducibility was assessed taking into account all occasions in which the test was performed with Cohen's kappa. Additionally, we calculated the Spearman correlation coefficient with the Medsger severity scale, Health Assessment Questionnaire score and SF-36 score. We included 70 patients with systemic sclerosis: age 17-78 (51±12) years, 65 (93%) were women, diffuse/limited subtype 64/36%, disease duration of 0.5-40 years. Optimal internal consistency for all categories of the final version of SySQ (Cronbach's α of 0.961) and intraobserver reliability in 2 tests over a 2-week interval (Cohen's kappa coefficient 0.618) and optimal interobserver reliability in 2 tests on the same day (Cohen's kappa coefficient 0.911).

    To validate the importance of the angiotensin II receptor isotypes and the lymphatic vessels in systemic sclerosis and idiopathic pulmonary fibrosis. We examined angiotensin II type 1 and 2 receptors and lymphatic vessels in the pulmonary tissues obtained from open lung biopsies of 30 patients with systemic sclerosis and 28 patients with idiopathic pulmonary fibrosis. Their histologic patterns included cellular and fibrotic non-specific interstitial pneumonia for systemic sclerosis and usual interstitial pneumonia for idiopathic pulmonary fibrosis. We used immunohistochemistry and histomorphometry to evaluate the number of cells in the alveolar septae and the vessels stained by these markers. Survival curves were also used. We found a significantly increased percentage of septal and vessel cells immunostained for the angiotensin type 1 and 2 receptors in the systemic sclerosis and idiopathic pulmonary fibrosis patients compared with the controls. A similar percentage of angiotensin 2 receptor positive vessel cells was observed in fibrotic non-specific interstitial pneumonia and usual interstitial pneumonia. A significantly increased percentage of lymphatic vessels was present in the usual interstitial pneumonia group compared with the non-specific interstitial pneumonia and control groups. A Cox regression analysis showed a high risk of death for the patients with usual interstitial pneumonia and a high percentage of vessel cells immunostained for the angiotensin 2 receptor in the lymphatic vessels. We concluded that angiotensin II receptor expression in the lung parenchyma can potentially control organ remodeling and fibrosis, which suggests that strategies aimed at preventing high angiotensin 2 receptor expression may be used as potential therapeutic target in patients with pulmonary systemic sclerosis and idiopathic pulmonary fibrosis.

    Antibodies directed against self-Ags are frequently considered detrimental, and have been shown to play a pathogenic role in certain autoimmune diseases. However, the presence of autoreactive Abs in normal individuals suggests that some autoantibodies could participate in normal physiology. Our previous studies demonstrated that monoclonal autoantibodies SCH94.03 and SCH94.32, generated from the splenocytes of uninfected SJL/J mice injected with normal homogenized spinal cord, promote central nervous system remyelination when passively transferred into syngeneic mice chronically infected with Theiler`s murine encephalomyelitis virus, an established experimental model of multiple sclerosis. In this study we show that these two monoclonal autoantibodies are identical, and have phenotypic characteristics of natural autoantibodies. By using a solid phase assay system, SCH94.03 and SCH94.32 showed reactivity toward several protein Ags and chemical haptens, with prominent reactivity toward spectrin, (4-hydroxy-3-nitrophenyl) acetyl, and fluorescein. Sequence analysis showed that both SCH94.03 and SCH94.32 were encoded by identical germline Ig light chain V{sub K}10/J{sub K}l and heavy chain V23/DFL16.1/J{sub H}2 genes, with no definitive somatic mutations. These results indicate that a natural autoantibody participates in a beneficial physiologic response to central nervous system injury. 60 refs., 7 figs.

    Full Text Available OBJETIVO. A osteopenia em pacientes com esclerodermia sistêmica foi descrita, radiologicamente, em mãos e, por densidade óssea, no terço proximal e distal do rádio. A redução da massa óssea, nesses pacientes, tem sido atribuída à isquemia, imobilização e à menopausa precoce. O objetivo deste estudo é analisar a densidade óssea na coluna, região proximal do fêmur e corpo todo de pacientes com esclerodermia sistêmica. PACIENTES E MÉTODO. Foram examinadas 25 pacientes caucasóides, sem outras condições que pudessem afetar o metabolismo ósseo. A média de idade das pacientes foi de 48 ± 12 anos, e o tempo de doença, de 7 ± 7 anos; 13 estavam na pós-menopausa há 8 ± 8 anos. A medida de massa óssea foi realizada na coluna, região proximal do fêmur e corpo todo, utilizando-se densitômetro de dupla emissão com fonte de raios X (Lunar - modelo DPX. RESULTADOS. Não houve diferença estatisticamente significante na densidade óssea das regiões avaliadas nas pacientes com esclerodermia sistêmica e as mulheres-controle pareadas para a idade, peso, altura e anos de menopausa. A densidade óssea das pacientes com forma limitada não foi diferente daquelas com a forma difusa. Pacientes com calcinose apresentaram menor densidade óssea na região proximal do fêmur que aquelas sem calcinose. CONCLUSÕES. Os autores concluíram que pacientes com esclerodermia sistêmica não apresentam perda de massa óssea. Portanto, a esclerodermia não é um fator de risco para o desenvolvimento de osteoporose generalizada.BACKGROUND - Osteopenia in systemic sclerosis (scleroderma patients was reported in X-ray studies of hands and by proximal and distal forearm bone mass measurement. It has been suggested that bone loss in these patients might be due to chronic ischemia, immobilization and early menopause.

    A 40 year old female visited the clinic for evaluation of Raynaud's phenomenon for a period of four years. The initial chest radiograph showed a fine reticular density and ground glass opacity with lower lobe predominance. These findings are consistent interstitial fibrosis. Additionally, high resolution CT showed multiple, small, coexisting nodular opacities, ranging from 3 to 7 mm in size in both lungs. These nodules grew up to 1.5 cm and showed moderate enhancement. Because of the rareness of intrapulmonary lymph node in patient of progressive systemic sclerosis, we couldn't exclude the possibility of malignancy. These nodules are turned out to be intrapulmonary lymph nodes on video assisted thoracoscopic lung biopsy.

    2016-07-01

    Multiple sclerosis is an inflammatory disease of the central nervous system for which there is currently no cure. Interferon-beta-1-alpha is worldwide one of the most widely used treatments in multiple sclerosis. To our knowledge there is one previous reported case of rhabdomyolysis associated with Interferon-beta treatment. We describe a 30 year old man with relapsing remitting multiple sclerosis who developed rhabdomyolysis and increased creatine kinase following Interferon-beta-1-alpha therapy. After the medication was discontinued, the patient rapidly improved. Clinicians should be aware of the possibility of rhabdomyolysis occurring during Interferon-beta-1-alpha therapy. In cases where patients complain of severe myalgia, and in particular if weakness is reported, creatine kinase activity should be measured to prevent irreversible rhabdomyolysis during Interferon-beta-1-alpha therapy in patients with multiple sclerosis.

    To evaluate the safety and efficacy of N-acetylcysteine (NAC) orally on digital microcirculation blood flow in patients with Raynaud's phenomenon (RP) secondary to systemic sclerosis (SSc). This was a randomized, double-blind, placebo-controlled trial in which 42 patients with SSc received oral NAC at a dose of 600mg tid (21 patients, mean age 45.6±9.5 years) or placebo (21 patients, mean age 45.0±12.7 years) for four weeks. The primary endpoint was the change in cutaneous microcirculation blood flow before and after cold stimulation measured by laser Doppler imaging (LDI) at weeks 0 and 4. The frequency and severity of RP and the number of digital ulcers were also measured at weeks 0 and 4. The adverse events were recorded in the fourth week. There was no significant change in digital blood flow assessed by LDI before or after cold stimulus after four weeks of NAC or placebo. Both groups showed significant improvement in the frequency and severity of RP attacks, with no difference between the two groups. At the end of the study, the placebo group had three digital ulcers, while the NAC group showed no ulcers. NAC was well tolerated and no patient discontinued the treatment. NAC orally at a dose of 1800mg/day showed no vasodilator effect on hands' microcirculation after four weeks of treatment in patients with RP secondary to SSc. Copyright © 2014 Elsevier Editora Ltda.

    This study evaluated the utility of the clearance time of inhaled diethylenetriamine pentaacetate (DTPA) to distinguish pulmonary vascular disease from early fibrosing alveolitis (FA) in patients with systemic sclerosis (SSc) It was hypothesized that this would be preserved in patients with vascular disease compared with FA, despite similar gas-transfer deficits and matching lung volumes, because of the preservation of alveolar epithelial integrity. All patients had SSc and were categorized into a control group (C; n=9), pulmonary vascular group (VAS; n=14) or FA group (n=14) dependent on the appearance on a computed tomography (CT) scan and the transfer factor of the lung for carbon monoxide (TL,CO) (VAS and FA {<=}70%, C {>=}80%). All patients had a forced vital capacity (FVC) of >80%. The TL,CO (median) was similar in the VAS (57.5%) and FA (60%) groups. There was a significant difference in median DTPA clearance half-times between FA (21.25 min) and VAS (46.5 min) (p=0.014) and between FA and C (84.5 min) (p=0.0004). No difference was found between VAS and C (p=0.0778). Follow-up data from the VAS group showed no subsequent development of FA on the CT scan and no decrease in FVC (n=13, mean 42 months). These results suggest that clearance of diethylenetriamine pentaacetate is preserved in patients likely to have pulmonary vascular disease and may be useful in distinguishing fibrosing alveolitis from vascular disease in systemic sclerosis.

    Multiple sclerosis continues to be a challenging and disabling condition but there is now greater understanding of the underlying genetic and environmental factors that drive the condition, including low vitamin D levels, cigarette smoking, and obesity. Early and accurate diagnosis is crucial and is supported by diagnostic criteria, incorporating imaging and spinal fluid abnormalities for those presenting with a clinically isolated syndrome. Importantly, there is an extensive therapeutic armamentarium, both oral and by infusion, for those with the relapsing remitting form of the disease. Careful consideration is required when choosing the correct treatment, balancing the side-effect profile with efficacy and escalating as clinically appropriate. This move towards more personalised medicine is supported by a clinical guideline published in 2018. Finally, a comprehensive management programme is strongly recommended for all patients with multiple sclerosis, enhancing health-related quality of life through advocating wellness, addressing aggravating factors, and managing comorbidities. The greatest remaining challenge for multiple sclerosis is the development of treatments incorporating neuroprotection and remyelination to treat and ultimately prevent the disabling, progressive forms of the condition.

    Eleven patients with a definite diagnosis of multiple sclerosis were examined in terms of correlations between the clinical features and the results of cranial computed tomography (CT), and magnetic resonance imaging (MRI). Results: In 5 of the 11 patients, both CT and MRI demonstrated lesions consistent with a finding of multiple sclerosis. In 3 patients, only MRI demonstrated lesions. In the remaining 3 patients, neither CT nor MRI revealed any lesion in the brain. All 5 patients who showed abnormal findings on both CT and MRI had clinical signs either of cerebral or brainstem - cerebellar lesions. On the other hand, two of the 3 patients with normal CT and MRI findings had optic-nerve and spinal-cord signs. Therefore, our results suggested relatively good correlations between the clinical features, CT, and MRI. MRI revealed cerebral lesions in two of the four patients with clinical signs of only optic-nerve and spinal-cord lesions. MRI demonstrated sclerotic lesions in 3 of the 6 patients whose plaques were not detected by CT. In conclusion, MRI proved to be more helpful in the demonstration of lesions attributable to chronic multiple sclerosis. (author)

    A study of several protective coating systems for use on aluminum in seawater/seacoast environments was conducted to review the developments made on protective coatings since early in the Space Shuttle program and to perform comparative studies on these coatings to determine their effectiveness for providing corrosion protection during exposure to seawater/seacoast environments. Panels of 2219-T87 aluminum were coated with 21 different systems and exposed to a 5 percent salt spray for 4000 hr. Application properties, adhesion measurements, heat resistance and corrosion protection were evaluated. For comparative studies, the presently specified Bostik epoxy system used on the SRB structures was included. Results of these tests indicate four systems with outstanding performance and four additional systems with protection almost as good. These systems are based on a chromated pretreatment, a chromate epoxy primer, and a polyurethane topcoat. Consideration for one of these systems should be included for those applications where superior corrosion protection for aluminum surfaces is required.

    Full Text Available Abstract Background Juvenile systemic sclerosis (JSS is a multisystem connective tissue disease characterized by skin fibrosis and internal organ involvement. It has a low prevalence, even in a tertiary facility setting. The purpose of the present study is to describe and analyze the clinical and laboratory characteristics of a group of children with JSS followed in a single center. Methods Clinical charts of children with a diagnosis of JSS who were seen at a tertiary referral center between 1995 and 2005 were reviewed. Clinical features were recorded and analysed. Results Twenty-three patients who met preliminary classification criteria for JSS were included. Age at first symptom attributable to JSS was 6 (1–14 years, The first symptom attributable to JSS was Raynaud's phenomenon in 14 cases. Proximal sclerosis (23 patients, 100%, sclerodactyly (21, 91%, Raynaud's phenomenon (19, 83%, and periungual capillaropathy (17, 74% were the most consistent clinical findings during follow-up. Respiratory involvement occurred in two thirds of our patients, and it manifested as dyspnea as well as abnormal imaging and/or pulmonary function tests; pulmonary hypertension was an infrequent finding. Dysphagia was the commonest gastrointestinal symptom (9 patients, 39%. The most frequent musculoskeletal symptom was arthralgia (14 children, 6%; symmetrical arthritis was found in 8 (35% patients. Periungual capillary abnormalities were evident during physical examination in 17 children; capillaroscopy revealed abnormalities in all 19 examined patients. ANA were present in 17 (74% children: homogeneous pattern was the most frequent (8 patients, nucleolar (5 and speckled (4 were less common. Conclusion Raynaud's phenomenon heralds the beginning of the disease. Capilaroscopy is a major adjuvant in the diagnosis, since autoantibody determination may not offer sensitive and specific markers. Skin and vascular manifestations are the most common clinical features

  15. Incidences and Risk Factors of Organ Manifestations in the Early Course of Systemic Sclerosis: A Longitudinal EUSTAR Study.

    Full Text Available Systemic sclerosis (SSc is a rare and clinically heterogeneous autoimmune disorder characterised by fibrosis and microvascular obliteration of the skin and internal organs. Organ involvement mostly manifests after a variable period of the onset of Raynaud's phenomenon (RP. We aimed to map the incidence and predictors of pulmonary, cardiac, gastrointestinal (GI and renal involvement in the early course of SSc.In the EUSTAR cohort, patients with early SSc were identified as those who had a visit within the first year after RP onset. Incident SSc organ manifestations and their risk factors were assessed using Kaplan-Meier methods and Cox regression analysis.Of the 695 SSc patients who had a baseline visit within 1 year after RP onset, the incident non-RP manifestations (in order of frequency were: skin sclerosis (75% GI symptoms (71%, impaired diffusing capacity for monoxide40mmHg (14%, and renal crisis (3%. In the heart, incidence rates were highest for diastolic dysfunction, followed by conduction blocks and pericardial effusion. While the main baseline risk factor for a short timespan to develop FVC impairment was diffuse skin involvement, for PAPsys>40mmHg it was higher patient age. The main risk factors for incident cardiac manifestations were anti-topoisomerase autoantibody positivity and older age. Male sex, anti-RNA-polymerase-III positivity, and older age were risk factors associated with incident renal crisis.In SSc patients presenting early after RP onset, approximately half of all incident organ manifestations occur within 2 years and have a simultaneous rather than a sequential onset. These findings have implications for the design of new diagnostic and therapeutic strategies aimed to 'widen' the still very narrow 'window of opportunity'. They may also enable physicians to counsel and manage patients presenting early in the course of SSc more accurately.

    Currently, it is generally accepted that multiple sclerosis (MS) is a complex multifactorial disease involving genetic and environmental factors affecting the autoreactive immune responses that lead to damage of myelin. In this respect, intrinsic or extrinsic factors such as emotional, psychological, traumatic, or inflammatory stress as well as a variety of other lifestyle interventions can influence the neuroendocrine system. On its turn, it has been demonstrated that the neuroendocrine system has immunomodulatory potential. Moreover, the neuroendocrine and immune systems communicate bidirectionally via shared receptors and shared messenger molecules, variously called hormones, neurotransmitters, or cytokines. Discrepancies at any level can therefore lead to changes in susceptibility and to severity of several autoimmune and inflammatory diseases. Here we provide an overview of the complex system of crosstalk between the neuroendocrine and immune system as well as reported dysfunctions involved in the pathogenesis of autoimmunity, including MS. Finally, possible strategies to intervene with the neuroendocrine-immune system for MS patient management will be discussed. Ultimately, a better understanding of the interactions between the neuroendocrine system and the immune system can open up new therapeutic approaches for the treatment of MS as well as other autoimmune diseases.

    In Japan, the classification of disease severity of idiopathic pulmonary fibrosis (IPF) (J-system) has been used in making decisions on medical care subsidies. The present J-system consists of arterial partial pressure of oxygen (PaO 2 ) and exercise desaturation in stages of I-IV. It provides a good prognostic classification in stages III and IV, but not in stages I and II. Therefore, we propose a revised system to improve discriminative ability in stages I and II. We compared the revised J-system with the present J-system using Cox proportional hazards model to predict mortality rate. We also evaluated the recently proposed GAP (Gender, Age and Physiology) system in comparison to both J-systems. Two-hundred and fifteen IPF patients were studied retrospectively. A univariate model showed that the present and revised J-systems and a modified GAP system were all significant prognostic factors. The C-statistic for discriminating prognosis was higher in the revised J-system than the modified GAP system and the present J-system (0.677, 0.652 and 0.659, respectively). The C-statistics of these models produced from the 10 000 bootstrap samples were similar to those of the original models, suggesting good internal validation (0.665 (95% CI: 0.621-0.705), 0.645 (0.600-0.686) and 0.659 (0.616-0.700), respectively). Multivariate analysis revealed that the revised J-system (P = 0.0038) and the modified GAP system (P = 0.0029) were independent prognostic factors. The revised J-system can provide a better mortality prediction than the present one. Both the revised J-system and the modified GAP system are independent and valuable tools for prognostication and clinical management for IPF. © 2017 Asian Pacific Society of Respirology.

    Full Text Available Rachel Brandstadter, Ilana Katz Sand Department of Neurology, Corinne Goldsmith Dickinson Center for Multiple Sclerosis, Icahn School of Medicine at Mount Sinai, New York, NY, USA Abstract: Natalizumab is a monoclonal antibody that acts as an α4 integrin antagonist to prevent leukocyte trafficking into the central nervous system. It is US Food and Drug Administration (FDA approved for the treatment of relapsing–remitting multiple sclerosis (RRMS. Natalizumab demonstrated high efficacy in Phase III trials by reducing the annualized relapse rate, preventing multiple sclerosis (MS lesion accumulation on magnetic resonance imaging, and decreasing the probability of sustained progression of disability. The leading safety concern with natalizumab is its association with progressive multifocal leukoencephalopathy (PML, a rare brain infection typically seen only in severely immunocompromised patients caused by reactivation of the John Cunningham virus (JCV. Careful analysis of risk factors for PML in natalizumab-treated MS patients, specifically the presence of anti-JCV antibodies, has led to risk mitigation strategies to improve safety. Additional biomarkers are under investigation to further aid risk stratification. Natalizumab’s high efficacy and favorable tolerability profile have led to a broad use by MS physicians, as both first- and second-line treatments. This review discusses the natalizumab efficacy, safety, and tolerability and finishes with pragmatic considerations regarding its use in clinical practice. Keywords: review, efficacy, safety, progressive multifocal leukoencephalopathy, JC virus, treatment

    Both oral and global health-related quality of life (HRQoL) are markedly impaired in SSc. In this study we aimed to determine the degree of association between oral HRQoL and global HRQoL in SSc. Subjects were recruited from the Canadian Scleroderma Research Group registry. Global HRQoL was measured using the Medical Outcomes Trust 36-item Short Form Health Survey (SF-36) and oral HRQoL with the Oral Health Impact Profile (OHIP). The Medsger Disease Severity Score was used to determine organ involvement. Multivariate regression models determined the independent association of the OHIP with the SF-36 after adjusting for confounders. This study included 156 SSc subjects. The majority (90%) were women, with a mean age of 56 years, mean disease duration 13.8 years (s.d. 8.5) and 29% of the subjects had dcSSc. Mean total OHIP score was 40.8 (s.d. 32.4). Mean SF-36 mental component summary (MCS) score was 49.7 (s.d. 11.1) and physical component summary (PCS) score was 37.0 (s.d. 10.7). In adjusted analyses, the total OHIP score was significantly associated with the SF-36 MCS and PCS, accounting for 9.7% and 5.6% of their respective variances. Measures of disease severity were not related to OHIP score. Oral HRQoL in SSc is independently associated with global HRQoL. Oral HRQoL, however, is not related to physician-assessed disease severity. This suggests that physicians may be disregarding issues related to oral health. HRQoL is an additional dimension of HRQoL not captured by generic instruments such as the SF-36. © The Author 2014.

    Full Text Available In the subsea pipeline gathering system, severe slugging flow is prone to occur. Severe slugging flow brings major threat to production and flow assurance in oil and gas industry due to periodical pressure oscillation and large liquid volume. Currently many researchers pay much more attention on L-shaped riser, catenaries, and S-shaped riser; little research has been made on hybrid riser, which is applied in the Africa West and Gulf of Mexico oil fields. Flow characteristics simulation for hybrid riser is made in this paper, using the one-dimensional and quasi-equilibrium model to simulate not only the riser-base pressure, severe slugging period, and the liquid slug length of the whole system but also base-pressure in the flexible pipe section. The calculated results match well with the experiment data. Besides, the influence of flexible pipe to the severe slugging characteristics of hybrid riser system is analyzed, which are significant for the determination of riser structure.

    Full Text Available Background/Aim. There are almost no studies on apraxia in people with multiple sclerosis. Although the white matter is damaged in MS, it is not the only location in which the pathological changes are present. Demyelinated lesions in the cortex have recently been recognized as important components of multiple sclerosis pathology. The aim of this study was to determine whether apraxia is present among people with MS, and the importance of demographic characteristics and impairment of functional systems at conceptualization and execution of movements. Methods. The experimental group consisted of 30 patients, mean age 51.34 ± 7.70 years. The patients in the experimental group were diagnosed with MS according to the McDonald criteria. The control group consisted of 30 healthy subjects, mean age 50.30 ± 10.47 years. For research purposes, we used the following instruments: Questionnaire for Collecting Demographic Data, Kurtzke Functional Systems Scores, Waterloo-Sunnybrook Apraxia Battery (WatAB. Execution of motion tasks that are a part of the Watwere incorporated in the System for the Observation and Analysis of Motor Behavior. Results. Our study showed that limb apraxia was common in people with MS. Apraxia was present during pantomime in 26.70% of the patients, and during the imitation of movements in 44.80% of the patients. Gender, age, education level, duration of disease and a form of MS did not determine the quality of conceptualization and execution of movements. The time elapsed from the last exacerbation was a determinant of quality of executed movements. Impairments of functional systems predicted impairments of movement execution. The expanded disability scale score correlated with the severity of apraxia. Conclusion. Our study confirm the presence of apraxia in MS. It is necessary to carry out further studies using functional magnetic resonance imaging, as well as the conduct longitudinal studies to determine the precise structure of

    2011-12-01

    Full Text Available Abstract The easily identifiable, ubiquitous demyelination and neuronal damage that occurs within the cerebral white matter of patients with multiple sclerosis (MS has been the subject of extensive study. Accordingly, MS has historically been described as a disease of the white matter. Recently, the cerebral cortex (gray matter of patients with MS has been recognized as an additional and major site of disease pathogenesis. This acknowledgement of cortical tissue damage is due, in part, to more powerful MRI that allows detection of such injury and to focused neuropathology-based investigations. Cortical tissue damage has been associated with inflammation that is less pronounced to that which is associated with damage in the white matter. There is, however, emerging evidence that suggests cortical damage can be closely associated with robust inflammation not only in the parenchyma, but also in the neighboring meninges. This manuscript will highlight the current knowledge of inflammation associated with cortical tissue injury. Historical literature along with contemporary work that focuses on both the absence and presence of inflammation in the cerebral cortex and in the cerebral meninges will be reviewed.

    The cephalosporin antibiotic ceftriaxone was evaluated as a potential therapeutic agent for the treatment of amyotrophic lateral sclerosis (ALS). The pharmacokinetics (PK) of ceftriaxone in plasma and cerebrospinal fluid (CSF) were investigated in 66 participants in a previously reported clinical trial. Their mean age was 51 years, and 65% were male. Participants were randomly assigned to 1 of 3 treatment groups receiving intravenous infusions (mean duration: 25 minutes) every 12 hours of either: placebo and placebo; 2 g ceftriaxone and placebo; or 2 g ceftriaxone twice. Mean steady-state plasma PK variables were: volume of distribution, 14 L (0.17 L/kg); elimination half-life, 8-9 h; total clearance, 17-21 mL/min (0.22-0.25 mL/min/kg). Values were not different between dosage groups. CSF PK analysis, determined through sparse CSF sampling, indicated apparent entry and elimination half-life values of 1.0 and 34 hours, respectively. With both dosage regimens, CSF concentrations were maintained above the target threshold of 1.0 µM (0.55 µg/mL) as determined from in vitro models. The plasma and CSF PK profiles of ceftriaxone were used as a basis for planning the Phase 3 clinical trial of ceftriaxone in ALS. © 2014, The American College of Clinical Pharmacology.

    Myasthenia gravis is an autoimmune disorder affecting neuromuscular junctions that has been associated with a small increased risk of amyotrophic lateral sclerosis (ALS). Here, we describe a retrospective series of seven cases with a concomitant diagnosis of ALS and myasthenia gravis, collected among the 18 French reference centers for ALS in a twelve year period. After careful review, only six patients strictly met the diagnostic criteria for both ALS and myasthenia gravis. In these patients, limb onset of ALS was reported in five (83%) cases. Localization of myasthenia gravis initial symptoms was ocular in three (50%) cases, generalized in two (33%) and bulbar in one (17%). Median delay between onset of the two conditions was 19 months (6-319 months). Anti-acetylcholine receptor antibodies testing was positive in all cases. All patients were treated with riluzole and one had an associated immune-mediated disease. In the one last ALS case, the final diagnosis was false-positivity for anti-acetylcholine receptor antibodies. The co-occurrence of ALS and myasthenia gravis is rare and requires strict diagnostic criteria. Its demonstration needs thoughtful interpretation of electrophysiological results and exclusion of false positivity for myasthenia gravis antibody testing in some ALS cases. This association may be triggered by a dysfunction of adaptive immunity. Copyright © 2016 Elsevier B.V. All rights reserved.

    Multiple sclerosis (MS) is a debilitating autoimmune disease of the central nervous system that damages axonal pathways through inflammation and demyelination. In order to address the need for a centralized application to manage and study MS patients, the MS e-Folder - a web-based, disease-specific electronic medical record system - was developed. The e-Folder has a PHP and MySQL based graphical user interface (GUI) that can serve as both a tool for clinician decision support and a data mining tool for researchers. This web-based GUI gives the e-Folder a user friendly interface that can be securely accessed through the internet and requires minimal software installation on the client side. The e-Folder GUI displays and queries patient medical records--including demographic data, social history, past medical history, and past MS history. In addition, DICOM format imaging data, and computer aided detection (CAD) results from a lesion load algorithm are also displayed. The GUI interface is dynamic and allows manipulation of the DICOM images, such as zoom, pan, and scrolling, and the ability to rotate 3D images. Given the complexity of clinical management and the need to bolster research in MS, the MS e-Folder system will improve patient care and provide MS researchers with a function-rich patient data hub.

    The objective of the project is twofold. One is to develop a severe accident database (DB) for the Korean Standard Nuclear Power plant (OPR-1000) and a DB management system, and the other to develop a localized computer code, MIDAS (Multi-purpose IntegrateD Assessment code for Severe accidents). The MELCOR DB has been constructed for the typical representative sequences to support the previous MAAP DB in the previous phase. The MAAP DB has been updated using the recent version of MAAP 4.0.6. The DB management system, SARD, has been upgraded to manage the MELCOR DB in addition to the MAAP DB and the network environment has been constructed for many users to access the SARD simultaneously. The integrated MIDAS 1.0 has been validated after completion of package-wise validation. As the current version of MIDAS cannot simulate the anticipated transient without scram (ATWS) sequence, point-kinetics model has been implemented. Also the gap cooling phenomena after corium relocation into the RPV can be modeled by the user as an input parameter. In addition, the subsystems of the severe accident graphic simulator are complemented for the efficient severe accident management and the engine of the graphic simulator was replaced by the MIDAS instead of the MELCOR code. For the user's convenience, MIDAS input and output processors are upgraded by enhancing the interfacial programs.

    Introduction Nailfold videocapillaroscopy (NVC) in systemic sclerosis (SSc) is a procedure commonly used for patient classification and subsetting, but not to define disease activity (DA). This study aimed to evaluate whether the number of micro-haemorrhages (MHE), micro-thrombosis (MT), giant capillaries (GC), and normal/dilated capillaries (Cs) in NVC could predict DA in SSc. Methods Eight-finger NVC was performed in 107 patients with SSc, and the total number of MHE/MT, GC, and the mean nu...

    It has been established that smoking has a profound impact on susceptibility and severity in some rheumatic diseases (e.g., rheumatoid arthritis), a mild impact in others (e.g., systemic lupus erythematosus) through epidemiological studies. And smoking is known to affect many inflammatory and autoimmune diseases through various mechanisms, including immunomodulation and chemical exposure. Although similar studies investigating the role of cigarette exposure in susceptibility to SSc have been rarely reported and specific mechanisms have never been established, the relationship between smoking and some SSc-related symptoms have been demonstrated during the last decade. However, due to the diversity of study designs, control populations, patient populations and the methodology used to determine smoking history, these results are contradictory in some respects. This paper will review current evidence on the association between smoking and SSc and summarize potential mechanisms. Copyright © 2017 Elsevier Inc. All rights reserved.

    2001-06-01

    We report a 23-year-old man suffering from an overlap syndrome of systemic scleroderma and dermatomyositis who died from severe dilated cardiomyopathy. Because his weakness involved predominantly muscles in the facio-scapulo-humeral regions, he was initially thought to have facioscapulohumeral muscular dystrophy (FSHD) at other hospitals. However, he had also Raynaud phenomenon and low voltages on electrocardiogram. His apparent facial weakness was mainly due to atrophic skin changes. Unlike FSHD, the deltoid and levator scapulae muscles were also atrophic. Deltoid muscle biopsy performed one year earlier at another hospital showed mild myopathic changes without inflammation, but there were scattered thick-walled endomysial capillaries, suggesting inflammatory myopathy. Biceps brachii muscle biopsy in our hospital showed marked inflammation with perifascicular atrophy. In this patient, the cardiac muscle involvement progressed together with the skeletal muscle inflammation before scleroderma became apparent.

    Full Text Available Objective: aim of the study is to assess the presence of spontaneous chromosome damage in patients affected by limited (lSSc or diffuse (dSSc Systemic Slerosis, using the micronucleus (MN assay. Methods: we evaluated MN frequency in cultured peripheral lymphocytes of 18 SSc and in a group of 20 healthy controls. Patients were also classified as ACA+, Scl70+, FAN+ according to the presence of the specific anti-nuclear antibodies. We also explored the hypothesis that the extent of cytogenetic alteration might be related to the severity of the pathological condition and/or to the immunological profile. Results: compared to controls, the patient group as a whole showed significantly higher MN frequencies (10.8±4.5 vs. 27.8±13.7, p<0.001. No correlation was found between spontaneous chromosome damage and severity of the disease, being MN frequency 33.1±17.0 and 19.8±2.7 in lSSc and dSSc, respectively. Interestingly, ACA+ subjects displayed the highest MN frequency (36.9±15.0, as compared to patients with different antibody pattern (Scl70+, FAN+; 19.7±8.2. Conclusions: our results confirm the presence of chromosomal damage in circulating lymphocytes of SSc patients and would suggest a key role of antibodies to the centromere in determining the observed cytogenetic anomalies.

    This work seeks to develop a methodology for identifying reliable biomarkers of disease activity, progression and outcome through the identification of significant associations between high-throughput flow cytometry (FC) data and interstitial lung disease (ILD) - a systemic sclerosis (SSc, or scleroderma) clinical phenotype which is the leading cause of morbidity and mortality in SSc. A specific aim of the work involves developing a clinically useful screening tool that could yield accurate assessments of disease state such as the risk or presence of SSc-ILD, the activity of lung involvement and the likelihood to respond to therapeutic intervention. Ultimately this instrument could facilitate a refined stratification of SSc patients into clinically relevant subsets at the time of diagnosis and subsequently during the course of the disease and thus help in preventing bad outcomes from disease progression or unnecessary treatment side effects. The methods utilized in the work involve: (1) clinical and peripheral blood flow cytometry data (Immune Response In Scleroderma, IRIS) from consented patients followed at the Johns Hopkins Scleroderma Center. (2) machine learning (Conditional Random Forests - CRF) coupled with Gene Set Enrichment Analysis (GSEA) to identify subsets of FC variables that are highly effective in classifying ILD patients; and (3) stochastic simulation to design, train and validate ILD risk screening tools. Our hybrid analysis approach (CRF-GSEA) proved successful in predicting SSc patient ILD status with a high degree of success (>82% correct classification in validation; 79 patients in the training data set, 40 patients in the validation data set). IRIS flow cytometry data provides useful information in assessing the ILD status of SSc patients. Our new approach combining Conditional Random Forests and Gene Set Enrichment Analysis was successful in identifying a subset of flow cytometry variables to create a screening tool that proved effective in

    Full Text Available The thalamus plays a crucial role in sensorimotor, cognitive and attentional circuit functions. Disruptions in thalamic connectivity are believed to underlie the symptoms of multiple sclerosis (MS. Therefore, assessing thalamocortical structural connectivity (SC and functional connectivity (FC may provide new insights into the mechanism of intrinsic functional plasticity in a large-scale neural network. We used resting-state FC measurement and diffusion tensor imaging probabilistic tractography to study the functional and structural integrity of the thalamocortical system in patients with relapsing-remitting MS (RRMS and matched healthy controls. In the thalamocortical connections of RRMS patients, we found lesion load-related regional FC in the right temporal pole, which reflected compensatory hyperconnectivity related to lesion-related demyelination. We also found significant correlations between increased diffusivity and slowed cognitive processing (PASAT or the impact of fatigue (MFIS-5, as well as between connective fiber loss and disease duration. Taken together, the evidence from SC and FC analysis of the thalamocortical system suggests that minimally disabled RRMS patients exhibit a dissociated SC-FC pattern and limited regional functional plasticity to compensate for the chronic demyelination-related loss of long-distance SC. These results also provide further evidence supporting the notion that MS is a disorder of anatomical disconnection.

These systems aim at improving the intelligibility of pathologic speech making it as natural as possible and close to the original voice of the speaker. The resynthesized utterances use new basic units, a new concatenating algorithm and a grafting technique to correct the poorly pronounced phonemes. The ASR responses are uttered by the new speech synthesis system in order to convey an intelligible message to listeners. Experiments involving four American speakers with severe dysarthria and two Acadian French speakers with sound substitution disorders (SSDs are carried out to demonstrate the efficiency of the proposed methods.

    The Satisfaction with Appearance Scale (SWAP) has been used to assess body image distress among people with the rare and disfiguring disease systemic sclerosis (SSc); however, it has not been validated across different languages groups. The objective was to examine differential item functioning of the SWAP among 856 Canadian English- or French-speaking SSc patients. Confirmatory factor analysis was used to evaluate the SWAP two-factor structure (Dissatisfaction with Appearance and Social Discomfort). The Multiple-Indicator Multiple-Cause model was utilized to assess differential item functioning. Results revealed that the established two-factor model of the SWAP demonstrated relatively good fit. Statistically significant, but small-magnitude differential item functioning was found for three SWAP items based on language; however, the cumulative effect on SWAP scores was negligible. Findings provided empirical evidence that SWAP scores from Canadian English- and French-speaking patients can be compared and pooled without concern that measurement differences may substantially influence results.

    Full Text Available Abstract Interstitial lung disease (ILD and pulmonary arterial hypertension (PAH are prevalent complications of systemic sclerosis (SSc and are currently the leading causes of death related to the disease. The accurate recognition of these conditions is therefore of utmost importance for patient management. A study was carried out with 24 SSc patients being followed at the Rheumatology Department of the Hospital de Clínicas of Universidade Federal do Paraná (UFPR and 14 healthy volunteers, with the objective of evaluating the usefulness of lung magnetic resonance imaging (MRI when assessing ILD in SS patients. The results obtained with lung MRI were compared to those obtained by computed tomography (CT of the chest, currently considered the examination of choice when investigating ILD in SS patients. The assessed population was predominantly composed of women with a mean age of 50 years, limited cutaneous SS, and a disease duration of approximately 7 years. In most cases, there was agreement between the findings on chest CT and lung MRI. Considering it is a radiation-free examination and capable of accurately identifying areas of lung tissue inflammatory involvement, lung MRI showed to be a useful examination, and further studies are needed to assess whether there is an advantage in using lung MRI instead of chest CT when assessing ILD activity in SS patients.

    A 54-year-old woman with progressive systemic sclerosis (PSS) was admitted to hospital because of dyspnea and chest pain. Echocardiogram revealed diffuse hypokinesis of the left ventricle (ejection fraction 24%). Methylprednisolone, heparin, and diuretics were administered, without benefit. Anemia, thrombocytopenia, and renal dysfunction rapidly progressed, and she died of heart failure on the 14th hospital day. Immunohistochemical study of the myocardial tissue showed mild to moderate cell infiltration, mainly consisting of natural killer (NK) cells, macrophages, cytotoxic T lymphocytes (CTLs), and T helper cells. Perforin, a cytolytic factor, was expressed in the infiltrating CTLs and NK cells, indicating that these cells were activated killer cells. Furthermore, human leukocyte antigen classes I and II, intercellular adhesion molecule-1, as well as costimulatory molecules B7-1, B7-2, and CD40, all of which are known not to be expressed in cardiac myocytes under normal conditions, were moderately to strongly expressed in cardiac myocytes. There was no detectable level of enterovirus genomes in the polymerase chain reaction products from the myocardial tissue of this patient. These findings strongly suggest that the infiltrating killer cells recognized cardiac myocytes as target cells and directly damaged them by releasing perforin. Enhanced expression of these antigens may have played an important role in the activation and cytotoxicity of the infiltrating killer cells. Absence of enterovirus genomes in the myocardial tissue may suggest that this autoimmune process is primarily induced by PSS.

    Alleles of interferon (IFN) regulatory factor 8 (IRF8) are associated with susceptibility to both systemic lupus erythematosus (SLE) and multiple sclerosis (MS). Although high-type I IFN is thought to be causal in SLE, type I IFN is used as a therapy in MS. We investigated whether IRF8 alleles were associated with type I IFN levels or serologic profiles in SLE and MS. Alleles that have been previously associated with SLE or MS were genotyped in SLE and MS patients. The MS-associated rs17445836G allele was associated with anti-double-stranded DNA (dsDNA) autoantibodies in SLE patients (meta-analysis odds ratio=1.92). The same allele was associated with decreased serum IFN activity in SLE patients with anti-dsDNA antibodies, and with decreased type I IFN-induced gene expression in peripheral blood mononuclear cell from anti-dsDNA-negative SLE patients. In secondary progressive MS patients, rs17445836G was associated with decreased serum type I IFN. Rs17445836G was associated with increased IRF8 expression in SLE patient B cells. In summary, IRF8 rs17445836G is associated with human autoimmune disease characterized by low-type I IFN levels, and this may have pharmacogenetic relevance as type I IFN is modulated in SLE and MS. The association with autoantibodies and increased IRF8 expression in B cells supports a role for rs17445836G in humoral tolerance.

    Systemic sclerosis (SSc) fibroblasts show resistance apoptosis mechanisms, which enhances the fibrosis stage of the disease. Impaired function of p53 upregulated modulator of apoptosis (PUMA) has been related to deficits in p53-dependant apoptosis pathway. This study aimed to evaluate the transcriptional levels of p53 and PUMA mRNAs in fibroblasts from SSc patients and compare it with healthy individuals. In this case-control study, skin biopsy samples were obtained from 19 patients with diffuse cutaneous SSc (DcSSc) and 16 healthy controls. Afterward, dermal fibroblasts were isolated and cultured. After extraction of total RNA from cultured fibroblasts, complementary DNA (cDNA) was synthesized. mRNA quantification was carried out using real-time PCR, SYBR Green PCR master mix, and specific primers for p53 and PUMA. No significant alteration was observed in mRNA expression levels of p53 and PUMA (P = .99 and .23, respectively) in fibroblasts from SSc patients compared with controls. Apoptosis pathways are impaired in fibroblasts from patients with SSc, leading to chronic fibrosis. Nonetheless, PUMA/p53 pathway may not be involved in dysfunction of apoptosis mechanisms in fibroblasts of patients with SSc. © 2017 Wiley Periodicals, Inc.

    Critical digital ischemia is a rare, but serious complication of systemic sclerosis (SSc) and is not always due solely to the non-inflammatory angiopathy that characterizes the SSc disease process. Our objective was to illustrate the range of presentations and causes of critical digital ischemia in patients with SSc in order to highlight how optimal management is dependent upon establishing the correct diagnosis. Five cases exemplifying differential diagnoses were identified and their case notes reviewed in order to extract clinically relevant data and images. A review of the literature was performed in PubMed in English. Causes of critical digital ischemia included typical micro-angiopathic changes and proximal (large vessel) disease. One case highlighted the difficulty of ascertaining whether an inflammatory cause is also present in SSc/SLE overlap syndrome. Two cases demonstrated embolic causes (thromboembolism due to atrial fibrillation and septic emboli). Critical digital ischemia in patients with SSc requires thorough investigation in order to avoid missing additional potentially modifiable causes including large vessel disease, inflammation, embolism, infection, and paraneoplastic syndromes. A firm evidence base for current medical and surgical interventions is lacking, highlighting the need for further research into the optimum management of this rare, but painful, debilitating, and limb-threatening complication of SSc.

    Full Text Available Background. Anxious and depressive symptoms are frequent in Systemic Sclerosis (SSc. Our objective is to assess their prevalence and association with district and global disability and psychological variables. Methods. 119 SSc patients were assessed by Hospital Anxiety Depression Scale (HADS. Clinical depression and anxiety were defined for HADS score cutoff ≥8. Patients were assessed for psychological symptoms (RSES, COPE-NIV, hand (HAMIS, CHFDS, fist closure, and hand opening and face disability (MHISS, mouth opening, global disability, and fatigue (HAQ, FACIT. Results. Both depression and anxiety in SSc are 36%. Depressive patients with comorbid anxiety have higher HADS-D score than patients with depression only (. HADS-A and -D are positively correlated with global disability, hands and mouth disability, fatigue, self-esteem and avoidance coping strategy, and, only HADS-A, also with social support (. By multiple regression, HADS-D is independently associated with FACIT-F (, RSES (, and MHISS total score (, together explaining 50% of variance. HADS-A is independently associated with RSES (, COPE-NIV SA (, COPE-NIV SS (, FACIT-F (, and MHISS mouth opening (, explaining 41% of variance. Conclusions. In SSc depression and anxiety correlate to local and global disabilities and psychological characteristics. Depressive patients with comorbid anxiety have higher level of depressive symptoms.

    This study aims to assess Growth differentiation factor-15 (GDF-15) level in Scleroderma patients and its relation to disease manifestations. This study included 55 scleroderma patients and 40 age and sex matched healthy volunteers. All patients were subjected to full history taking, thorough clinical examination, and laboratory investigations. GDF-15 serum levels were analyzed in patients and controls using human GDF-15 immunoassay Quantikine ELISA kit. The GDF-15 serum level was significantly higher in Systemic sclerosis (SSc) patients in comparison to healthy control individuals, p-value = 0.004. In addition, the GDF-15 serum levels increased in a significant way in patients with diffuse SSc than those with limited SSc, p = 0.026. Also, we had discovered a significant positive correlation between serum GDF-15 levels and the modified Rodnan score of the SSc patients, r = 0.442, p = 0.001 and a significant association was found between high GDF-15 level and SSc patients with interstitial pulmonary fibrosis (IPF) as compared to healthy controls (p = 0.002). However, no significant difference was found between SSc patients without IPF and healthy subjects regarding GDF-15 level (p = 0.106). GDF-15 serum levels were elevated in patients with SSc and correlated with the extent of skin fibrosis, and it was found to be higher in SSc patients with IPF. Such results may suggest a pivotal role of GDF-15 in fibrotic changes in SSc, and GDF-15 could be a treatment target in SSc patients in future.

    Systemic sclerosis (SSc) affects multiple physical, psychological, and social domains and is associated with impaired health-related quality of life (HRQOL).We compared the HRQOL of SSc patients with individuals in the general population and patients with other common chronic diseases. HRQOL of SSc patients in the Canadian Scleroderma Research Group registry was measured using version 2 of the Medical Outcomes Trust Short Form-36 (SF-36). Results were compared to US general population norms and scores reported for patients with other common chronic diseases, namely heart disease, lung disease, hypertension, diabetes, and depression. SF-36 scores were available for 504 SSc patients (86% women, mean age 56 yrs, mean disease duration since onset of first non-Raynaud's manifestation of SSc 11 yrs). The greatest impairment in SF-36 subscale scores appeared to be in the physical functioning, general health, and role physical domains. SF-36 subscale and summary scores in SSc were significantly worse compared to US general population norms for women of similar ages, except for mental health and mental component summary score, which were not significantly different, and were generally comparable to or worse than the scores of patients with other common chronic conditions. HRQOL of patients with SSc is significantly impaired compared to that of the general population and is comparable to or worse than that of patients with other common chronic conditions.

    Introduction Potassium voltage-gated channel shaker-related subfamily member 5 (KCNA5) is implicated in vascular tone regulation, and its inhibition during hypoxia produces pulmonary vasoconstriction. Recently, a protective association of the KCNA5 locus with systemic sclerosis (SSc) patients with pulmonary arterial hypertension (PAH) was reported. Hence, the aim of this study was to replicate these findings in an independent multicenter Caucasian SSc cohort. Methods The 2,343 SSc cases (179 PAH positive, confirmed by right-heart catheterization) and 2,690 matched healthy controls from five European countries were included in this study. Rs10744676 single-nucleotide polymorphism (SNP) was genotyped by using a TaqMan SNP genotyping assay. Results Individual population analyses of the selected KCNA5 genetic variant did not show significant association with SSc or any of the defined subsets (for example, limited cutaneous SSc, diffuse cutaneous SSc, anti-centromere autoantibody positive and anti-topoisomerase autoantibody positive). Furthermore, pooled analyses revealed no significant evidence of association with the disease or any of the subsets, not even the PAH-positive group. The comparison of PAH-positive patients with PAH-negative patients showed no significant differences among patients. Conclusions Our data do not support an important role of KCNA5 as an SSc-susceptibility factor or as a PAH-development genetic marker for SSc patients. PMID:23270786

    Systemic sclerosis (SSc) is a chronic, progressive autoimmune disease with major end-organ involvement. Much attention has been focused on the management of physical and clinical manifestations; however, the effect of the disease and treatment on the patient's identity, relationships, functioning, and mental well-being are less known. We aimed to describe the patients' perspectives and experiences of living with SSc. Electronic databases were searched to October 2014. Thematic synthesis was used to analyze the findings. We included 26 studies involving 463 patients. Six key themes were identified: distressing appearance transformation (disturbing facial changes, stigmatizing sickness, unrecognizable self), palpable physical limitations (bodily restrictions, frustrating mind-body disconnect, pervasive fatigue, disabling pain), social impairment (breaking intimacy, struggling to fulfill family responsibilities, maintaining work, losing independence), navigating uncertainty (diagnostic ambiguity, medically fending for oneself, unpredictable course of illness), alone and misunderstood (fearful avoidance of fellow patients, invisible suffering), and gradual acceptance and relative optimism (adapting to change and accepting limitations, taking a positive spin, cautious hoping, empowering relationships, valuing medical support). SSc is a rare and unpredictable illness that undermines patients' sense of certainty and control and impairs their self-image, identity, and daily functioning. Patient-centered care that encompasses strategies to promote self-esteem, resilience, and self-efficacy may help to improve treatment satisfaction and health and quality of life outcomes for patients with SSc.

    SSc is a rare autoimmune CTD characterized by thickening and fibrosis of skin and internal organs. There is significant mortality and no cure. Sleep disturbance has been identified as an important contributor to poor quality of life. The objective was to investigate socio-demographic and medical factors potentially associated with sleep disturbance in SSc. The sample consisted of patients from the Canadian Scleroderma Research Group's (CSRG) 15-centre, pan-Canadian Registry assessed with the 8-item Patient-Reported Outcome Measurement Information System (PROMIS) sleep disturbance scale short form, version 1.0. Pearson's correlations were used to assess bivariate association of socio-demographic and medical variables with PROMIS sleep scores. The independent association of PROMIS sleep disturbance scores and factors previously identified as associated with sleep disturbance in the general population, in SSc and other rheumatic diseases, was assessed using multiple linear regression. Among 397 patients in the study (88% female, mean age 57.5 years), 25% (n = 98) had diffuse cutaneous SSc. Mean duration since onset of non-RP symptoms was 10.6 years. Number of gastrointestinal symptoms (standardized regression coefficient β = 0.19, P = 0.001), pain severity (β = 0.21, P sleep disturbance. Gastrointestinal symptoms, pain and pruritus were associated with sleep disturbance in SSc. Additional research is needed on sleep in SSc so that well-informed sleep interventions can be developed and tested.

    To evaluate if defective activation of renal functional reserve (RFR) in systemic sclerosis (SSc) without clinical signs of renal involvement predicts the risk of developing clinically relevant renal damage. Twenty-eight normotensive SSc patients with normal renal function and no urinary abnormalities were submitted to an intravenous amino acid load to activate RFR. Nineteen patients (six with diffuse cutaneous SSc (dcSSc)) had an RFR activation defect, while nine (two with dcSSc) showed normal RFR. All patients were followed up for 5 years, with periodic evaluation of renal function, urinary protein excretion and systemic blood pressure (BP). At admission, patients with normal RFR had lower BP than those with abnormal RFR; no age, disease duration or creatinine clearance (CCr) differences were found. Five years later, patients with abnormal RFR showed, with respect to basal values, a significantly higher CCr reduction than patients with normal RFR (mean percent decrease 15.4 ± 9.5 vs 2.6 ± 3.8, pRFR, 13 (68.4%) showed a CCr reduction of ≥ 2 ml/min/year, with a final CCr of ≤ 70 ml/min in eight cases; two patients developed microalbuminuria and 10 grade 1 or 2 systemic hypertension. Significant CCr reduction rates were found in eight patients with high BP and in five patients who remained normotensive. No patient with normal RFR had proteinuria or high BP during follow-up. Lack of RFR activation is an early sign of renal involvement in SSc, and is a harbinger of an increased risk of developing renal insufficiency and systemic hypertension.

    Full Text Available The available clinical outcome measures of disability in multiple sclerosis are not adequately responsive or sensitive.To investigate the feasibility of inertial sensor-based gait analysis in multiple sclerosis.A cross-sectional study of 80 multiple sclerosis patients and 50 healthy controls was performed. Lower-limb kinematics was evaluated by using a commercially available magnetic inertial measurement unit system. Mean and standard deviation of range of motion (mROM, sROM for each joint of lower limbs were calculated in one minute walking test. A motor performance index (E defined as the sum of sROMs was proposed.We established two novel observer-independent measures of disability. Hip mROM was extremely sensitive in measuring lower limb motor impairment, being correlated with muscle strength and also altered in patients without clinically detectable disability. On the other hand, E index discriminated patients according to disability, being altered only in patients with moderate and severe disability, regardless of walking speed. It was strongly correlated with fatigue and patient-perceived health status.Inertial sensor-based gait analysis is feasible and can detect clinical and subclinical disability in multiple sclerosis.

    Trauma is a major cause of morbidity and mortality; hence severity scales are important adjuncts to trauma care in order to characterize the nature and extent of injury. Trauma scoring models can assist with triage and help in evaluation and prediction of prognosis in order to organise and improve trauma systems. Given the wide variety of scoring instruments available to assess the injured patient, it is imperative that the choice of the severity score accurately match the application. Even though trauma scores are not the key elements of trauma treatment, they are however, an essential part of improvement in triage decisions and in identifying patients with unexpected outcomes. This article provides the reader with a compendium of trauma severity scales along with their predicted death rate calculation, which can be adopted in order to improve decision making, trauma care, research and in comparative analyses in quality assessment.
