Abstract
The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this consensus provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes.

Abstract
OBJECTIVES A clinically practical tool to assess skin biomechanical properties rapidly and accurately is still lacking. Our aim was to examine the intra- and inter-observer reproducibility of a myotonometer for objective skin property assessment in systemic sclerosis (SSc), comparing it with the modified Rodnan skin score (mRSS), and distinguishing patients from healthy controls. METHOD Thirty-four patients (21 limited and 13 diffuse SSc), and 31 age and gender-matched healthy controls were enrolled. Skin tone and stiffness were measured at four different anatomical sites (the forearm, hand, leg, and foot) using a myotonometer. The correlation between the mRSS and skin properties was assessed. Also, hand functionality was evaluated for possible correlations between the variables. The differences in skin properties between dcSSc and lcSSc patients, and healthy controls were assessed using variance analysis. RESULTS Intra- and inter-examiner reproducibility were excellent (ICC = 0.70 to 0.98) for tone and stiffness except for non-dominant hand tone, which showed good reliability (ICC = 0.64 to 0.74). Stiffness and tone values of the hands, forearms, and feet significantly correlated with mRSS total score (r = 0.40 to 0.71, p < 0.05). Additionally, tone and stiffness of the hands and forearms moderately correlated with hand function (p < 0.05). Tone and stiffness values increased in patients with dcSSc compared to healthy controls, or patients with lcSSc, at the hands, forearms, and legs (p < 0.05). CONCLUSIONS Our findings emphasize the potential utility of the myotonometer for assessing skin properties and differentiating SSc patients from controls, demonstrating its promise as a valuable clinical evaluation tool in this context. Key Points •The myotonometer displayed excellent intra- and inter-examiner reproducibility for assessing skin properties. •Skin tone and stiffness parameters well correlated with the mRSS scores. •The myotonometer can distinguish patients with diffuse cutaneous SSc from healthy controls.

Abstract
Systemic sclerosis, also known as scleroderma or SSc, is a condition characterized by significant heterogeneity in clinical presentation, disease progression, and response to treatment. Consequently, the design of clinical trials to successfully identify effective therapeutic interventions poses a major challenge. Recent advancements in skin molecular profiling technologies and stratification techniques have enabled the identification of patient subgroups that may be relevant for personalized treatment approaches. This narrative review aims at providing an overview of the current status of skin gene expression analysis using computational biology approaches and highlights the benefits of stratifying patients upon their skin gene signatures. Such stratification has the potential to lead toward a precision medicine approach in the management of SSc.

Optical Coherence Tomography Angiography Is a Useful Tool for Distinguishing Primary Raynaud's Phenomenon from Systemic Sclerosis and/or Very Early Disease of Systemic Sclerosis. Diagnostics (Basel) 2023; 13:2607.

Abstract
This cross-sectional study aimed to compare optical coherence tomography angiography (OCT-A) findings in patients with primary Raynaud's phenomenon (PRP; n = 22), very early disease of systemic sclerosis (VEDOSS; n = 19), and systemic sclerosis (SSc; 25 patients with limited cutaneous SSc (lcSSc) and 13 patients with diffuse cutaneous SSc (dcSSc)). Whole, parafoveal, and perifoveal superficial capillary plexus (SCP) vessel densities (VDs), deep capillary plexus VDs, and whole, inside, and peripapillary VDs were significantly higher in the PRP group (p < 0.001). In the lcSSc group, the FAZ perimeter was significantly higher than that in the VEDOSS group (p = 0.017). Retinal nerve fiber layer VDs were significantly lower in the lcSSc group than in the PRP and VEDOSS groups (p < 0.001). The whole and peripapillary optic disc VDs of the VEDOSS group were significantly higher than in the lcSSc group (p < 0.001). Whole SCP VDs (94.74% sensitivity, 100.00% specificity) and parafoveal SCP VDs (89.47% sensitivity, 100.00% specificity) showed the best performance in distinguishing patients with SSc from those with PRP. OCT-A seems to have potential diagnostic value in differentiating patients with PRP from patients with SSc and VEDOSS, and there is potential value in assessing prognostic roles, since findings from OCT-A images could be early indicators of retinal vascular injury long before overt SSc symptoms develop.

Abstract
Pulmonary vascular dysfunction is characterized by remodeling and loss of microvessels in the lung and is a major manifestation of chronic lung diseases (CLD). In murine models of CLD, the small arterioles and capillaries are the first and most prevalent vessels that are affected by pruning and remodeling. Thus, visualization of the pulmonary arterial vasculature in three dimensions is essential to define pruning and remodeling both temporally and spatially and its role in the pathogenesis of CLD, aging, and tissue repair. To this end, we have developed a novel method to visualize and quantitate the murine pulmonary arterial circulation using microcomputed tomography (µCT) imaging. Using this perfusion technique, we can quantitate microvessels to approximately 6 µM in diameter. We hypothesize that bleomycin-induced injury would have a significant impact on the arterial vascular structure. As proof of principle, we demonstrated that as a result of bleomycin-induced injury at peak fibrosis, significant alterations in arterial vessel structure were visible in the three-dimensional models as well as quantification. Thus, we have successfully developed a perfusion methodology and complementary analysis techniques, which allows for the reconstruction, visualization, and quantitation of the mouse pulmonary arterial microvasculature in three-dimensions. This tool will further support the examination and understanding of angiogenesis during the development of CLD as well as repair following injury.

Abstract
SSc is a systemic autoimmune disease of unknown etiology characterized by frequently progressive cutaneous and internal organ fibrosis causing severe disability, organ failure and high mortality. A remarkable feature of SSc is the extension of the fibrotic alterations to nonaffected tissues. The mechanisms involved in the extension of fibrosis have remained elusive. We propose that this process is mediated by exosome microvesicles released from SSc-affected cells that induce an activated profibrotic phenotype in normal or nonaffected cells. Exosomes are secreted microvesicles involved in an intercellular communication system. Exosomes can transfer their macromolecular content to distant target cells and induce paracrine effects in the recipient cells, changing their molecular pathways and gene expression. Confirmation of this hypothesis may identify the molecular mechanisms responsible for extension of the SSc fibrotic process from affected cells to nonaffected cells and may allow the development of novel therapeutic approaches for the disease.

Abstract
Objective To assess the relationship between functional disability and health-related quality of life (HRQoL) among systemic sclerosis (SSc) patients. Methodology This cross-sectional study was carried out on 78 adults who met the classification criteria for SSc defined by the American College of Rheumatology/European League of Rheumatology (ACR/EULAR)-2013. The Bangla version of Short Form 36 (SF-36) and Health Assessment Questionnaire-Disability Index (HAQ-DI) were used to measure HRQoL and functional disability in SSc patients. Results The patients' median [IQR] HAQ-DI was 1.4 [0.6–2.1], with 37.2% having a mild functional disability, 33.3 percent having a moderate functional disability, and 29.5 percent having a severe functional disability. The hygiene and activity domains of the HAQ-DI obtained the highest scores, 2.0 [0.0–3.0] and 2.0 [1.0–3.0], respectively. The Physical Component Summary (PCS) and Mental Component Summary (MCS) of the SF-36 had median [IQR] values of 26.2 [15.0–58.1] and 42.0 [19.6–60.6]. The highest score was 50.0 [25.0–75.0] in social functioning. The PCS of the SF-36 was moderately correlated with the HAQ-DI (rs = − 0.629, P < 0.001) and the MCS of the SF-36 was weakly correlated with the HAQ-DI ((rs = − 0.344, P < 0.001). Age, female sex, and incomplete fist closure substantially influenced functional status. Calcinosis, Raynaud's Phenomenon, and flexion contracture significantly diminished the quality of life. Conclusions Functional disability negatively affects health-related quality of life. Age, Musculoskeletal, and skin involvement are significantly associated with poor quality of life and functional disability. Therefore, treatment strategies should be aimed at reducing functional disability, which will enhance the HRQoL of SSc patients.

Abstract
Systemic sclerosis (SSc) is a complex autoimmune connective tissue disease with distinct pathological hallmarks (ie, inflammation, vasculopathy, fibrosis) that may predominate at different stages in the disease course with varying severity. Initial efforts to classify patients with SSc identified a subset of patients with very early SSc. These patients possessed signs of SSc (eg, Raynaud phenomenon, SSc specific autoantibodies and/or nailfold capillary abnormalities) without fulfilling complete SSc classification criteria. Recognizing the inherent value in early diagnosis and intervention in SSc, researchers have endeavored to identify risk factors for progression from very early SSc to definite SSc. The present review summarizes the clinical phenotype of patients with very early and early SSc. Through a scoping review of recent literature, this review also describes risk factors for progression to definite SSc with a focus on the specific clinical features that arise early in the SSc disease course (eg, diffuse cutaneous sclerosis, interstitial lung disease, esophageal dysfunction, renal crisis, cardiac involvement). In addition to clinical risk factors, this review provides evidence for how biological data (ie, serological, genomic, proteomic profiles, skin bioengineering methods) can be integrated into risk assessment models in the future. Furthering our understanding of biological features of very early SSc will undoubtedly provide novel insights into SSc pathogenesis and may illuminate new therapeutic targets to prevent progression of SSc.

Abstract
ZusammenfassungUnter dem Begriff Sklerodermie ist eine heterogene Gruppe von Erkrankungen
zusammengefasst, die eine kutane Sklerose gemeinsam haben. Die einzelnen
Erkrankungen variieren in der Beteiligung betroffener Strukturen wie Haut,
Fettgewebe, Muskulatur, Gelenkstrukturen, Knochen, innerer Organe und der damit
einhergehenden Krankheitsausprägung. Es lassen sich
grundsätzlich zwei verschiedene Subtypen unterscheiden: die lokalisierte
Sklerodermie (LoS) und die systemische Sklerose (SSc), die sich jeweils in
weitere Subgruppen unterteilen lassen. Es handelt sich um zwei verschiedene
Erkrankungen, die sich in der Ausprägung der Hautsklerosierung, der
Beteiligung innerer Organe, im Antikörper-Profil, im
Krankheitsmanagement sowie der Prognose unterscheiden. Darüber hinaus
gibt es Krankheitsbilder, die eine Sklerodermie imitieren und daher als
sklerodermie-artige Erkrankungen oder auch als Pseudosklerodermien bezeichnet
werden. Um die richtige Diagnose stellen zu können, ist ein
standardisiertes diagnostisches Vorgehen bedeutsam. Die frühe
Diagnosestellung ist wichtig, um frühzeitige eine Therapie einleiten zu
können, und so funktionelle kutane und extrakutane
Einschränkungen und auch kosmetische Schäden gering halten zu
können.

Abstract
BACKGROUND Autologous hematopoietic stem cell transplantation (AHSCT) treats patients with severe and progressive systemic sclerosis (SSc). However, basic mechanisms associated with the therapeutic efficacy of the procedure are not entirely understood. We aimed to evaluate how AHSCT affects skin fibrosis in SSc patients. METHODS Clinical data, serum, and skin samples from 39 SSc patients who underwent AHSCT were retrospectively evaluated. Skin biopsies were analyzed by immunohistochemistry with anti-MMP-1, -MMP-2, -MMP-3, -MMP-9, -TIMP-1, -α-SMA, -TGF-β, and -NF-κB p65 antibodies, and stained with hematoxylin and eosin and picrosirius red to assess skin thickness and collagen density, respectively. Serum samples were evaluated by Multiplex Assay for COL1A1, COL4A1, FGF-1, MMP-1, MMP-3, MMP-12, MMP-13, PDGF-AA, PDGF-BB, S100A9, and TIMP-1 levels and compared to healthy controls. RESULTS After AHSCT, SSc patients showed clinical improvement in skin involvement, assessed by modified Rodnan's skin score (mRSS). Histologically, collagen density and skin thickness decreased after AHSCT. Immunohistochemical analyses showed increased expression of MMP-2, MMP-3, MMP-9, and TIMP-1 after AHSCT, whereas expression of NF-κB p65 decreased. At baseline, serum levels of COL4A1 and S100A9 were higher than in healthy controls. Serum levels of S100A9 normalized after AHCST in SSc patients compared to controls. Serum levels of PDGF-AA, PDGF-BB, TIMP-1, and MMP-1 decreased, while COL1A1 increased after AHSCT in SSc patients. No changes were detected in MMP-3, MMP-12, MMP-13, and FGF-1 serum levels after AHSCT. CONCLUSIONS Our results suggest that the therapeutic effects of AHSCT on skin fibrosis are related to changes in molecules associated with connective tissue maintenance and inflammation in SSc.

Abstract
Fibrosis can be defined as an excessive and deregulated deposition of extracellular matrix proteins, causing loss of physiological architecture and dysfunction of different tissues and organs. In the skin, fibrosis represents the hallmark of several acquired (e.g. systemic sclerosis and hypertrophic scars) and inherited (i.e. dystrophic epidermolysis bullosa) diseases. A complex series of interactions among a variety of cellular types and a wide range of molecular players drive the fibrogenic process, often in a context-dependent manner. However, the pathogenetic mechanisms leading to skin fibrosis are not completely elucidated. In this scenario, an increasing body of evidence has recently disclosed the involvement of Notch signalling cascade in fibrosis of the skin and other organs. Despite its apparent simplicity, Notch represents one of the most multifaceted, strictly regulated and intricate pathways with still unknown features both in health and disease conditions. Starting from the most recent advances in Notch activation and regulation, this review focuses on the pro-fibrotic function of Notch pathway in fibroproliferative skin disorders describing molecular networks, interplay with other pro-fibrotic molecules and pathways, including the transforming growth factor-β1, and therapeutic strategies under development.

Abstract
New strategies for early diagnosis and careful follow-up of systemic sclerosis are urgently needed. We unconventionally used a video capillaroscopy system to measure the amount of sweating on finger pads, and investigated its clinical significance. Thirty-three Japanese patients who were diagnosed with typical or pre-clinical stage patients of systemic sclerosis were included in this study. Five healthy subjects were also included. Among twenty-one patients with typical systemic sclerosis that fulfilled ACR/EULAR 2013 classification criteria, seven had increased sweating levels. On the other hand, among twelve pre-clinical stage patients that did not fulfill the classification criteria, no patient showed increase in finger sweating. We found that there was statistically significant difference. The ratio of diffuse cutaneous systemic sclerosis was also found to be significantly higher in subjects with increased amounts of sweating than in subjects with normal levels. Furthermore, the positivity of topoisomerase I antibody was statistically higher in patients with increased sweating levels than in those without. These results indicated that measurement of finger sweating levels may be a useful tool for early diagnosis and clarification of pathogenesis in this disease.

Abstract
Systemic sclerosis is a rare chronic autoimmune disease with extensive microvascular injury, damage of endothelial cells, activation of immune responses, and progression of tissue fibrosis in the skin and various internal organs. According to epidemiological data, women's populations are more susceptible to systemic sclerosis than men. Until now, various therapeutic options are employed to manage the symptoms of the disease. Since stem cell-based treatments have developed as a novel approach to rescue from several autoimmune diseases, it seems that stem cells, especially mesenchymal stem cells as a powerful regenerative tool can also be advantageous for systemic sclerosis treatment via their remarkable properties including immunomodulatory and anti-fibrotic effects. Accordingly, we discuss the contemporary status and future perspectives of mesenchymal stem cell transplantation for systemic sclerosis.

Abstract
Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by dysregulation of the immune system, vascular damage, and fibrosis of the skin and internal organs. Patients with SSc show a heterogeneous phenotype and a range of clinical courses. Therefore, biomarkers that are helpful for precise diagnosis, prediction of clinical course, and evaluation of the therapeutic responsiveness of disease are required in clinical practice. SSc-specific autoantibodies are currently used for diagnosis and prediction of clinical features, as other biomarkers have not yet been fully vetted. Krebs von den Lungen-6 (KL-6), surfactant protein-D (SP-D), and CCL18 have been considered as serum biomarkers of SSc-related interstitial lung disease. Moreover, levels of circulating brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) can provide diagnostic information and indicate the severity of pulmonary arterial hypertension. Assessment of several serum/plasma cytokines, chemokines, growth factors, adhesion molecules, and other molecules may also reflect the activity or progression of fibrosis and vascular involvement in affected organs. Recently, microRNAs have also been implicated as possible circulating indicators of SSc. In this review, we focus on several potential SSc biomarkers and discuss their clinical utility.

Abstract
Systemic Sclerosis (SSc) is a complex auto-immune connective tissue disease combining inflammatory, vasculopathic and fibrotic manifestations. Skin effectively recapitulates the main pathogenic processes and therefore is a good organ to decipher the disease pathophysiology, which remains unclear. However, culturing primary skin cells is SSc can be a major issue due to small sample size combined to skin fibrosis. Here, we present a protocol allowing to isolate and culture the four main types of skin cells: dermal cells (microvascular dermal endothelial cells—HDMECs—and fibroblasts) and epidermal cells (keratinocytes and melanocytes), from a single 4 mm-punch biopsy, at a low cost. The present protocol has been optimized to fit SSc skin cells particularities. Such technique allows to culture primary cells, crucial to study the disease pathophysiology, as well as to isolate cells in order to perform immediate molecular biology experiments such as single-cell transcriptomic. Cells grown from biopsies are also suitable for various types of experiments such as immunocytochemistry, Western blot, RT-qPCR or functional in vitro assays (angiogenesis, migration, etc.). Ultimately, they can be used for experimental 3D cell culture models such as reconstructed skin.

Abstract
OBJECTIVES To examine the incidence, predictors and outcomes associated with severe gastrointestinal (GI) disease in a large inception SSc cohort. METHODS SSc subjects with <2 years of disease duration were identified from two multicentre cohorts. Severe GI disease was defined as: malabsorption, hyperalimentation, pseudo-obstruction and/or ⩾10% weight loss in association with the use of antibiotics for bacterial overgrowth or oesophageal stricture. Kaplan-Meier, multivariate logistic regression and Cox proportional hazard analyses were performed to determine the cumulative incidence rate, independent clinical correlates and mortality rate associated with severe GI disease. A longitudinal mixed model was used to assess the impact of severe GI disease on the Short Form Health Survey. RESULTS In this inception SSc cohort, the probability of developing severe GI disease was estimated at 9.1% at 2 years and 16.0% at 4 years. In multivariate analysis, severe GI disease was associated with inflammatory myositis (odds ratio 4.68, 95% CI 1.65, 13.24), telangiectasias (odds ratio 2.45, 95% CI 1.19, 5.04) and modified Rodnan skin score (odds ratio 1.03, 95% CI 1.01, 1.07). Severe GI disease was associated with a >2-fold increase in the risk of death (hazard ratio 2.27, 95% CI 1.27, 4.09) and worse health-related quality of life [Short Form Health Survey physical (β = -2.37, P = 0.02) and mental (β = -2.86, P = 0.01) component summary scores]. CONCLUSION Severe GI disease is common in early SSc and is associated with significant morbidity and increased mortality. More research is needed to understand, prevent and mitigate severe GI disease in SSc.

Abstract
The objective is to detect any possible correlation between the modified Rodnan skin score (mRSS) and dermal thickness (DT) measured by skin high-frequency ultrasound (US) and the percentage of circulating fibrocytes in patients with limited cutaneous systemic sclerosis (lcSSc). Eight lcSSc patients and five healthy subjects (control group, CNT) were enrolled. The skin involvement was evaluated by mRSS and US (18 and 22 MHz probes) in all 13 subjects in the 17 standard skin areas evaluated by mRss. Circulating fibrocytes were isolated from the peripheral blood mononuclear cells (PBMCs) of all lcSSc patients and the CNT group to analyze their percentage at baseline time (T0) when the experiments started with PBMCs' isolation and collection and after 8 days of culture (T8). Non-parametric tests were used for the statistical analysis. A positive correlation between the percentage of circulating fibrocytes at T0, mRSS (p = 0.04 r = 0.96), and DT-US, evaluated by the 22 MHz and the 18 MHz probes (p = 0.03, r = 0.66 and p = 0.05, r = 0.52, respectively), was observed in lcSSc patients. Conversely, at T8, there was no correlation (p > 0.05) between these parameters in lcSSc group. In the CNT group, no correlations between mRSS or DT-US and the percentage of circulating fibrocytes were observed both at T0 and T8. The study shows the presence of a significant relationship between the percentage of circulating fibrocytes and DT, as evidenced by both mRSS and US, in limited cutaneus SSc. This observation may well suggest the reasonable hypothesis of a crucial contribution of circulating fibrocytes to skin fibrosis progression, which might be considered as further biomarkers.

Abstract
Systemic scleroderma/sclerosis (SSc) is an autoimmune connective tissue disease, which can lead to esophageal motor dysfunction and gastroesophageal reflux disease (GERD). Nocturnal GERD symptoms may be associated with sleep disturbances, which in turn can drastically affect well-being and fatigue levels. We hypothesized that GERD symptoms would be associated with poorer sleep in patients with SSc. Rheumatologist established SSc patients completed the following questionnaires: the UCLA scleroderma clinical trial consortium gastrointestinal tract instrument (GIT) 2.0 questionnaire; the Pittsburgh sleep quality index (PSQI); the fatigue severity scale (FSS); the multidimensional gastrointestinal symptom severity index (GSSI). Poor sleep quality was defined by a PSQI total score >5. Questionnaires were completed by 287 patients [mean (SD) age = 59 (14) years; female = 243]. Poor sleep quality was identified in 194 (68%) patients. Patients with poor sleep quality reported less sleep time and increased fatigue compared to those with normal sleep scores. SSc patients with poor sleep had significantly higher GIT Reflux scores (P < .001), and poor sleep was more frequent in those with moderate/severe versus mild/no heartburn on GISSI (P < .001). Narcotic and antidepressant use was significantly more frequent in SSc patients with poor sleep quality. Multivariable logistic regression supported the association between GERD symptoms and poor sleep after controlling for age, sex, and body mass index (BMI) (2.53, 95% confidence interval (CI) 1.52-4.25; P < .001). The association remained after controlling for narcotic and antidepressant use (2.20, 95% CI 1.29-3.73; P < .001). SSc patients who reported GERD symptoms were also more likely to report poor sleep quality. Future studies should examine mechanisms underlying nocturnal GERD symptoms in SSc patients, and the impact of improved GERD symptom control on sleep quality.

Abstract
Systemic sclerosis (SSc) is a complex autoimmune connective tissue disease combining inflammatory, vasculopathic and fibrotic manifestations. Skin features, which give their name to the disease and are considered as diagnostic as well as prognostic markers, have not been thoroughly investigated in terms of therapeutic targets. CCN proteins (CYR61/CCN1, CTGF/CCN2, NOV/CCN3 and WISP1-2-3 as CCN4-5-6) are a family of secreted matricellular proteins implicated in major cellular processes such as cell growth, migration, differentiation. They have already been implicated in key pathophysiological processes of SSc, namely fibrosis, vasculopathy and inflammation. In this review, we discuss the possible implication of CCN proteins in SSc pathogenesis, with a special focus on skin features, and identify the potential actionable CCN targets.

Abstract
Systemic sclerosis (SSc) is a severe auto-immune disease, characterized by vasculopathy and fibrosis of connective tissues. SSc has a high morbidity and mortality and unfortunately no disease modifying therapy is currently available. A key cell in the pathophysiology of SSc is the myofibroblast. Myofibroblasts are fibroblasts with contractile properties that produce a large amount of pro-fibrotic extracellular matrix molecules such as collagen type I. In this narrative review we will discuss the presence, formation, and role of myofibroblasts in SSc, and how these processes are stimulated and mediated by cells of the (innate) immune system such as mast cells and T helper 2 lymphocytes. Furthermore, current novel therapeutic approaches to target myofibroblasts will be highlighted for future perspective.

Abstract
BACKGROUND Clinical manifestations of skin fibrosis are very variable and ambiguous, making its management quite critical and challenging. The lack of appropriate established pharmacological interventions make its treatment even more complicated. Intricate details of the underlying pathogenesis are thus imperative to further explore different treatment possibilities. Of note, the TGF-β/Smad signaling axis and epithelial to mesenchymal transition (EMT) are the principal offenders in this fibrotic disorder. OBJECTIVE Our current study is aimed at demonstrating the antifibrotic and anti-inflammatory potential of nimbolide, a triterpene derived from Indian traditional plant neem, in a murine model of Bleomycin-induced scleroderma. METHODS Male C57BL/6 mice were administered with Bleomycin injections subcutaneously, daily for 28 days, at a constant site on the dorsum of the mice. Treatment with nimbolide lasted from day 1 to day 28. At the time of study termination, the injected sites were collected and stored suitably to conduct further molecular experiments and protein expression studies. RESULTS AND CONCLUSION The results of our study show that nimbolide can significantly intervene in the TGF-β/Smad signaling axis and the consequent EMT process, thus attenuating deposition of extracellular matrix. Nimbolide also profoundly caused the regression of established inflammation-driven fibrosis, thus demonstrating both antifibrotic and anti-inflammatory activities. Another commendable finding of this study is that nimbolide was able to decrease the levels of LOXL2, a collagen cross-linker, which is aberrantly expressed in scleroderma. Although further mechanistic studies are required, our study displays nimbolide for the first time as a potent antifibrotic agent which can be used as a pharmacological intervention for the treatment of scleroderma.

Abstract
Little is known about the anatomic distribution of cutaneous chronic graft-versus-host disease (cGVHD). Using data from the cGVHD Consortium Improving Outcomes Assessment Study, we describe the frequency and extent of erythema and superficial and deep sclerosis in 8 anatomic sites in patients with incident disease (ie, new cGVHD diagnosis within 3 months of study entry) receiving systemic therapy. Of 339 patients with incident disease, 182 (54%) had skin involvement. When an extremity was involved, the same type of disease was present contralaterally in 92% of cases, revealing a high level of symmetry. As anticipated, erythema was the most common incident feature; however, sclerotic skin involvement at the time of cGVHD diagnosis was more common than has been suggested by previous studies. Erythema occurred in 155 (85%) and sclerosis in 53 (29%) of the patients with skin involvement (46% and 16%, respectively, of the entire cohort of 339 incident cGVHD cases). Erythema was least common on the lower extremities (n = 71; 39% of patients with skin involvement). Moveable sclerosis was rare on the head, neck, and scalp (n = 4; 2%). Deep sclerosis did not occur in this region, and instead was most likely to occur on the upper extremities (n = 14; 8%) and lower extremities (n = 14; 8%). More than one-half of patients with erythema (n = 107; 58.7%) had diffuse involvement (4 or more of 8 sites involved), compared with less than one-third of those with sclerosis (n = 16; 30.2%).

Abstract
Systemic Sclerosis (SSc) is a chronic autoimmune disease whose origin and pathogenesis are not yet well known. Recent studies are allowing a better definition of the disease. However, few studies have been performed based on metabolomics. In this way, this study aims to find altered metabolites in SSc patients in order to improve their diagnosis, prognosis and treatment. For that, 59 SSc patients and 28 healthy volunteers participated in this study. Urine and plasma samples were analysed by a fingerprinting metabolomic approach based on HPLC-ESI-QTOF-MS. We observed larger differences in urine than plasma metabolites. The main deregulated metabolic families in urine were acylcarnitines, acylglycines and metabolites derived from amino acids, specifically from proline, histidine and glutamine. These results indicate perturbations in fatty acid beta oxidation and amino acid pathways in scleroderma patients. On the other hand, the main plasma biomarker candidate was 2-arachidonoylglycerol, which is involved in the endocannabinoid system with potential implications in the induction and propagation of systemic sclerosis and autoimmunity.

Abstract
Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations. This article reviews the clinical presentation with emphasis on cutaneous disease, etiopathogenesis, diagnosis, and treatment options available for the different forms of scleroderma firstly and for scleroderma-like disorders, including scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis, chronic graft-versus-host disease, porphyria cutanea tarda, diabetic stiff-hand syndrome (diabetic cheiroartropathy), and other minor forms. This latter group of conditions, termed also scleroderma mimics, sclerodermiform diseases, or pseudosclerodermas, shares the common thread of skin thickening but presents with distinct cutaneous manifestations, skin histology, and systemic implications or disease associations, differentiating each entity from the others and from scleroderma. The lack of Raynaud's phenomenon, capillaroscopic abnormalities, or scleroderma-specific autoantibodies is also important diagnostic clues. As cutaneous involvement is the earliest, most frequent and characteristic manifestation of scleroderma and sclerodermoid disorders, dermatologists are often the first-line doctors who must be able to promptly recognize skin symptoms to provide the affected patient a correct diagnosis and appropriate management.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disorder that is typically divided into limited cutaneous systemic sclerosis and diffuse cutaneous systemic sclerosis. Scleroderma renal crisis (SRC) is a severe complication of SSc and typically presents with new-onset hypertension and a reduction in renal functioning. In patients presenting with typical features of SRC, treatment with an angiotensin-converting enzyme inhibitor along with dialysis as needed is typically initiated empirically. Renal biopsy is not recommended in patients with SSc presenting with typical features of SRC. Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare co-occurrence with SSc, in around 2.5% to 9% of patients. AAV is an inflammatory condition that can result in renal failure due to mononuclear cell infiltration and destruction of blood vessels. Treatment of AAV is drastically different from SRC and typically consists of immunosuppressants and dialysis if needed. SRC and AAV can only reliably be distinguished by renal biopsy. We present a rare case of a 70-year-old female with limited cutaneous systemic sclerosis who presented to the emergency department with new-onset renal failure. Her serology was found to be positive for antinuclear antibodies and myeloperoxidase antibodies, resulting in a renal biopsy, which revealed an acute necrotizing vasculitis consistent with AAV. We suggest consideration of a renal biopsy in patients with SSc who present with new-onset renal failure, especially with nonresponse to SRC treatment or positive serology.

Abstract
Objectives The aim was to define clinical characteristics and long-term survival of patients with dcSSc and positive ACA. Methods We identified all cases of ACA+ SSc in our cohort (n = 1313). Those with dcSSc (ACA+ diffuse) were compared with representative groups of consecutive ACA+ patients with limited subset (ACA+ limited) and ACA− dcSSc (non-ACA diffuse). Results Thirty-five patients (2.7%) were ACA+ diffuse. The peak modified Rodnan skin score was not significantly different between the dcSSc subgroups, but it occurred later in the disease course in ACA+ diffuse (88.54 vs 30.65 months, P < 0.001). Patterns of organ involvement were different between the groups. ACA+ diffuse had a higher incidence of interstitial lung disease than ACA+ limited (22.86 vs 4.43%, P = 0.001), but lower than non-ACA diffuse (41.18%, P = 0.042). More patients developed pulmonary hypertension in the ACA+ diffuse group (28.5 vs 12.0% ACA+ limited or 12.0% non-ACA diffuse), although this was attributable to the longer follow-up in these patients. The cumulative incidence of pulmonary hypertension was not different from the other two groups. The incidence of cardiac involvement was similar between the dcSSc groups, and scleroderma renal crisis was more frequent in the non-ACA diffuse group. Survival in ACA+ patients was similar in both subsets, whereas non-ACA diffuse had higher mortality. Conclusion ACA+ dcSSc is uncommon and has a distinct clinical phenotype, with a more insidious onset of skin and organ involvement. Even in dcSSc, ACA appears protective for organ-based complications, namely interstitial lung disease and scleroderma renal crisis, and is associated with a better survival than expected in dcSSc.

Abstract
Skin involvement in SSc is an important marker of disease activity, severity and prognosis, making the assessment of skin a key issue in SSc clinical research. We reviewed the published data assessing skin involvement in clinical trials and summarized the major conclusions important in SSc clinical research. A systematic literature review identified randomized controlled trials using skin outcomes in SSc. Analysis examined the validity of the different skin measures based on literature findings. Twenty-two randomized controlled trials were found. The average study duration was 10.2 (s.d. 4.5) months, mean (s.d.) sample size 32.4 (32.6) and 26.7 (27.8) in intervention and control arms, respectively. The 17-site modified Rodnan skin score is a fully validated primary outcome measure in diffuse cutaneous SSc. Skin histology seems to be an appropriate method for evaluation of skin thickness. These findings have important implications for clinical trial design targeting skin involvement in SSc.

Abstract
Systemic sclerosis (SSc) is a chronic inflammatory disease with complex pathogenesis, based on the sophisticated interplay of injury to the vascular endothelium, exaggerated tissue regeneration and fibrosis, and extensive immune abnormalities. The role of regulatory T cells (Tregs) in the development of SSc has started being studied during the last decade with new aspects being disclosed continuously, in parallel with the better understanding of Tregs physiology. There is a general agreement in the medical literature regarding the decreased functional capacity of circulating Tregs in SSc. Some patients, particularly those with active disease, may have increased numbers of circulating Tregs, representing the inhibitory response of the immune system to its inappropriate activation or occurring as a compensatory move for Tregs' decreased suppressive ability. Decreased pool of circulating Tregs can be seen in other SSc patients, with even lower Treg percentages seen in patients with long-standing disease. Skin-resident Tregs are depleted in advanced SSc but can be active and have a role in earlier disease stages. In addition to diminished suppressive ability, Tregs can contribute to SSc evolution by their microenvironment-dependent transformation to pathogenic effector T cells of Th17 or Th2 lineages with respective pro-inflammatory or pro-fibrotic activity. The current data on the effects of existing treatment modalities, including autologous stem cell transplantation, on Tregs function in SSc, is controversial, not being sufficiently elaborated.

Abstract
Background The aim of the study was to detect by skin high-frequency ultrasound (US) possible subclinical skin involvement in patients affected by limited cutaneous systemic sclerosis (lcSSc), in those skin areas apparently not affected by the disease on the basis of a normal modified Rodnan skin score (mRSS). Differences in dermal thickness (DT) in comparison with healthy subjects were investigated. Methods Fifty patients with lcSSc (age 62 ± 13 years (mean ± SD), disease duration 5 ± 5 years) and 50 sex-matched and age-matched healthy subjects (age 62 ± 11 years) were enrolled. DT was evaluated by both mRSS and US at the usual 17 skin areas (zygoma, fingers, dorsum of the hands, forearms, upper arms, chest, abdomen, thighs, lower legs and feet). Non-parametric tests were used for the statistical analysis. Results Subclinical dermal involvement was detected by US even in the skin areas in patients with lcSSc, who had a normal local mRSS. In addition, statistically significantly higher mean DT was found in almost all skin areas, when compared to healthy subjects (p < 0.0001 for all areas). In particular, DT was significantly greater in patients with lcSSc than in healthy subjects in four out of six skin areas with a normal mRSS (score = 0) (upper arm, chest and abdomen), despite the clinical classification of lcSSc. Conclusions This study strongly suggests that subclinical dermal involvement may be detectable by US even in skin areas with a normal mRSS in patients classified as having lcSSc. This should be taken into account during SSc subset classification in clinical studies/trials.

Abstract
The availability of highly purified recombinant human relaxin, serelaxin, has allowed clinical trials to be conducted in several indications and the elucidation of its pharmacology in human subjects. These studies have demonstrated that serelaxin has unique haemodynamic properties that are likely to contribute to organ protection and long-term outcome benefits in acute heart failure. Clinical observations support its consideration for therapeutic use in other patient populations, including those with chronic heart failure, coronary artery disease, portal hypertension and acute renal failure.

Abstract
Phospholipase D4 (PLD4) is a newly identified protein expressed in microglia. However, the function of PLD4 in tumor-associated macrophages (TAMs) is unknown. In the present study, we revealed that the expression of PLD4 was located in macrophages in the colon cancer mesenchymal and lymph nodes as shown by immunohistochemical analysis. furthermore, its expression was associated with clinical staging of colon cancer. Then, THP-1 as a cell model induced into TAMs. Western blot and RT-PCR analysis showed that PLD4 was mainly presented in M1 phenotype TAMs. The secretion of pro-inflammatory cytokines in M1 macrophages was significantly reduced after the expression of PLD4 inhibited by PLD4-siRNA. Furthermore, co-cultured with condition-medium from control or PLD4-siRNA M1 macrophages for 24 h, cell apoptosis, cycle and proliferation of cancer cells improved compared to control. These results indicated that PLD4 could be involved in the activation process of M1 phenotype macrophages.

Abstract
Scleroderma is a group of skin-fibrosing diseases for which there are no effective treatments. A feature of the skin fibrosis typical of scleroderma is atrophy of the dermal white adipose tissue (DWAT). Adipose tissue contains adipose-derived mesenchymal stromal cells (ADSCs) that have regenerative and reparative functions; however, whether DWAT atrophy in fibrosis is accompanied by ADSC loss is poorly understood, as are the mechanisms that might maintain ADSC survival in fibrotic skin. Here, we have shown that DWAT ADSC numbers were reduced, likely because of cell death, in 2 murine models of scleroderma skin fibrosis. The remaining ADSCs showed a partial dependence on dendritic cells (DCs) for survival. Lymphotoxin β (LTβ) expression in DCs maintained ADSC survival in fibrotic skin by activating an LTβ receptor/β1 integrin (LTβR/β1 integrin) pathway on ADSCs. Stimulation of LTβR augmented the engraftment of therapeutically injected ADSCs, which was associated with reductions in skin fibrosis and improved skin function. These findings provide insight into the effects of skin fibrosis on DWAT ADSCs, identify a DC-ADSC survival axis in fibrotic skin, and suggest an approach for improving mesenchymal stromal cell therapy in scleroderma and other diseases.

Abstract
Systemic sclerosis (SSc) is a rare multisystem connective tissue disorder characterized by the triad fibrosis, vasculopathy and immune dysregulation. This chronic disease has a significant impact on the orofacial region that is involved in more than two-thirds of the cases. SSc patients can show a wide array of oral manifestations, which are usually associated with a severe impairment of the quality of life. They often present a decreased the salivary flow and a reduced mouth opening that contribute substantially to the worsening of the oral health status. Therefore, SSc patients require specific and multidisciplinary interventions that should be initiated as early as possible. The identification of specific radiological and clinical signs at the early stage will improve the management of such patients. This study reviews the wide spectrum of orofacial manifestations associated with SSc and suggests clues for the oral management that remains challenging.

Abstract
Systemic sclerosis (SSc, scleroderma) is an often-fatal disease characterized by connective tissue fibrosis of skin and internal organs. In scleroderma, there is an excessive production and accumulation of extracellular matrix (ECM) components resulting from an increase in collagen synthesis and matrix stability. Understanding how this how excessive ECM is produced and remodeled may represent a novel therapeutic approach. In this review, the transcription factors and collagen-modifying enzymes underlying collagen overexpression and enhancing stability in SSc are discussed. Moreover, the role of matrix stiffness in promoting fibrosis via a feed-forward mechanism is discussed. Indeed, the emerging evidence is that enhanced ECM remodeling resulting in increased ECM stiffness may be sufficient in itself to sustain persistence fibrosis in SSc.

Abstract
The skin is the most common organ system involved in patients with systemic sclerosis (SSc). Nearly all patients experience cutaneous symptoms, including sclerosis, Raynaud's phenomenon, digital ulcers, telangiectasias, and calcinosis. In addition to posing functional challenges, cutaneous symptoms are often a major cause of pain, psychological distress, and body image dissatisfaction. The present article reviews the main features of SSc-related cutaneous manifestations and highlights an evidence-based treatment approach for treating each manifestation. This article also describes novel treatment approaches and opportunities for further research in managing this important clinical dimension of SSc.

Abstract
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.

Abstract
Telangiectasia, or dilated blood vessels, may represent a benign condition or a marker of a much more serious internal or cutaneous malignancy (e.g., mycosis fungoides). They can be generalized or localized in distribution. 'Localized telangiectasia? can be macular or papular. Macular ones can be further divided into two major categories: primary and secondary. They can occur on their own (primary), after skin injury (e.g., sun damage, post-radiation therapy, after prolonged topical steroid application), or may arise due to an underlying condition (secondary). While telangiectases can spring from a multitude of possible causes, the location of the lesions, in combination with a careful history and exmination, often helps in elucidating the correct diagnosis. A patient with localized telangiectasia as a manifestation of malignancy may be difficult to diagnose, however the diagnosis is one of exclusion, and a thorough evaluation should be performed before diagnosing this condition. This article reviews possible conditions to consider in these patients and suggests an approach to their evaluation.

Abstract
BACKGROUND Bovine hereditary zinc deficiency (BHZD) is an autosomal recessive disorder of cattle, first described in Holstein-Friesian animals. Affected calves suffer from severe skin lesions and show a poor general health status. Recently, eight calves with the phenotypic appearance of BHZD have been reported in the Fleckvieh cattle population. RESULTS In spite of the similar disease phenotypes, SLC39A4, the gene responsible for BHZD in Holstein-Friesian was excluded as underlying gene for the disorder in the affected Fleckvieh calves. In order to identify the disease-associated region, genotypes of eight affected calves obtained with the Illumina BovineHD BeadChip comprising 777,962 SNPs were contrasted with the genotypes of 1,339 unaffected animals. A strong association signal was observed on chromosome 21 (P = 5.87 × 10(-89)). Autozygosity mapping in the eight affected animals revealed a common segment of extended homozygosity encompassing 1,023 kb (BTA 21: 70,550,045 - 71,573,501). This region contains 17 genes/transcripts, among them two genes encoding gastro-intestinal zinc transporters (CRIP1, CRIP2). However, no mutation that was compatible with recessive inheritance could be detected in these candidate genes. One of the affected calves was re-sequenced together with 42 unaffected Fleckvieh animals. Analysis of the sequencing data revealed a nonsense mutation (p.W215X) in a phospholipase encoding gene (PLD4) as candidate causal polymorphism. To confirm the causality, genotypes of the p.W215X-mutation were obtained from 3,650 animals representing three different breeds. None of the unaffected animals was homozygous for the defect allele, while all eight affected calves were homozygous. The deleterious effect of the mutation is manifested in a significantly lower survival rate of descendants from risk matings when compared with the survival rate of descendants from non-risk matings. The deleterious allele has an estimated frequency of 1.1% in the Fleckvieh population. CONCLUSION Our results provide strong evidence that a newly identified recessive disorder in the Fleckvieh population is caused by a nonsense mutation in PLD4, most likely resulting in an impaired function of the encoded protein. Although the phenotype of affected calves strongly resembles BHZD, a zinc deficiency resulting from malabsorption is unlikely to be responsible for the diseased Fleckvieh calves.

Abstract
Background Systemic sclerosis (SSc) is a connective tissue fibrotic disease for which there is no effective treatment. Traditional Chinese Medicine (TCM), such as the Yiqihuoxue formula used in Shanghai TCM-integrated Hospital, has shown the efficacy of anti-fibrosis in clinical applications. This study was aiming to dissect the anti-fibrotic mechanism of Yiqihuoxue treatment for SSc. Methods Bleomycin-induced mice and SSc dermal fibroblasts were treated with Yiqihuoxue decoction; NIH-3T3 fibroblasts were exposed to exogenous TGF-β1, and then cultured with or without Yiqihuoxue decoction. Luciferase reporter gene assay was used to determine the activity of Smad binding element (SBE). Quantitative reverse transcription-polymerase chain reaction (RT-PCR) was used to examine the mRNA levels of extracellular matrix (ECM) genes. The protein levels of type I collagen, Smad3 and phosphorylated-Smad3 (p-Smad3) were detected by western blotting. Student’s t-tests were used to determine the significance of the results. Results Bleomycin-induced mice, SSc dermal fibroblasts and TGF-β1-induced NIH/3T3 fibroblasts showed higher levels of ECM gene transcriptions and collagen production. In addition, the phosphorylation level of Smad3 and activity of SBE were significantly increased after exogenous TGF-β1 induction. Whereas, Yiqihuoxue treatment could obviously attenuate fibrosis in bleomycin-induced mice, down regulate ECM gene expressions and collagen production in SSc dermal fibroblasts and TGF-β1-induced NIH/3T3 fibroblasts. Furthermore, the aberrantly high phosphorylation level of Smad3 and activity of SBE in the TGF-β1-induced NIH/3T3 fibroblasts were also dramatically decreased by Yiqihuoxue treatment. Conclusions Yiqihuoxue treatment could effectively reduce collagen production via down-regulating the phosphorylation of Smad3 and then the activity of SBE, which are involved in the TGF-β pathway and constitutively activated in the progression of SSc.

Abstract
Introduction We aimed to evaluate the effect of menopause on skin thickening, as measured by the modified Rodnan skin score (mRSS), in women with systemic sclerosis (SSc). Methods We identified women with either limited or diffuse SSc, aged ≥ 18 years, enrolled within the Canadian Scleroderma Research Group (CSRG) cohort, between 2004 and 2011. As part of the CSRG cohort, subjects undergo annual assessments with standardized questionnaires and physical examinations. We performed multivariate regression analyses using generalized estimating equation (GEE) to determine the effect of menopause on the mRSS, adjusting for relevant covariates including notably age, follow-up time, and disease duration. Results We identified 1070 women with SSc, contributing a total of 3546 observations over the study period. Of these women, at baseline, 65% had limited disease and 35% diffuse disease. In multivariate analyses, we observed a substantial effect of postmenopausal status on the mean mRSS in women with diffuse disease subtype [−2.62 units, 95% confidence interval (CI) -4.44, −0.80] and significant interaction between menopausal status and disease subtype (2.04 units, 95% CI 0.20, 3.88). The effect of postmenopausal status on the mean mRSS was smaller in women with limited SSc (−0.58, 95% CI −1.50, 0.34). Conclusions Our results suggest that menopause has a substantial effect on skin thickening in diffuse SSc, with postmenopausal status being associated with a lower mean mRSS compared to premenopausal status.

Abstract
Systemic sclerosis sine scleroderma is a subtype of scleroderma, which is characterized by involvement of visceral organs, but no characteristic skin alteration. The involved organs could be kidneys, heart, gastrointestinal system, and lungs. Interstitial lung disease (ILD) is one of the pulmonary manifestations of sine scleroderma. We report a 38-year-old woman presenting with chill, fever, generalized malaise, dyspnea on exertion, and dry cough with a history of Raynaud's phenomenon, who was evaluated by physical examination, spirometry, and computed tomography scan, that all lead to the diagnosis of ILD. Combination of high-titer positive anti-nuclear antibody, high erythrocyte sedimentation rate, positive C-reactive protein, and ILD could be explained by sine scleroderma.

Abstract
Ultrasound (US) is a cost-effective, noninvasive, accessible imaging modality that clinicians use at the point of care to assess disease activity and therapeutic efficacy in different rheumatic conditions. However, its utility has been prevalently demonstrated in the field of chronic arthritides. Only in the last few years there was an interest to explore the potential of US beyond the musculoskeletal area. In this way, preliminary US data about the assessment of the different targets involved in systemic sclerosis such as joints, tendons, skin, vessels, and lung have been provided. The main purpose of this US review is to provide an overview of the potential role of US in the multi-target assessment of SSc and to discuss the current evidence supporting its relevance and applications in daily clinical practice.

Proteinuria in systemic sclerosis: reversal by ACE inhibition. Rheumatol Int 2013; 33:2225-30. [PMID: 23446441 PMCID: PMC3751210 DOI: 10.1007/s00296-013-2691-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2012] [Accepted: 01/28/2013] [Indexed: 01/13/2023]
Abstract
In systemic sclerosis (SSc), kidney damage is a major clinical problem which can lead to a deleterious outcome. Recently, in diabetes mellitus, early detection of proteinuria and treatment with angiotensin-converting enzyme (ACE) inhibitors has been shown to slow progression of kidney disease and to improve prognosis. In this study, we investigated the spontaneous course of proteinuria in SSc and the effects of ACE inhibitor therapy. Proteinuria was determined in SSc patients with urine protein electrophoresis. SSc patients with proteinuria (n = 31) were followed over a median of 12 months. Of all 31 patients with pathologic urine protein electrophoresis investigated in this study, 9 patients (29 %) had additional microalbuminuria and 4 patients (12.9 %) showed increased total urinary protein. ACE inhibitor treatment was subsequently given to 23 patients. A total of 8 patients remained untreated for various reasons. Proteinuria resolved in 74 % of patients treated with ACE inhibitors, whereas in the untreated group, remission was observed only in 25 % (p = 0.014). Improvement of proteinuria was predominantly achieved in patients with recently diagnosed proteinuria and short disease duration. In patients with SSc and proteinuria, initiation of ACE inhibitor therapy resulted in a significant decrease in proteinuria.

Abstract
Localized scleroderma (also called morphea) is a term encompassing a spectrum of sclerotic autoimmune diseases that primarily affect the skin, but also might involve underlying structures such as the fat, fascia, muscle, and bones. Its exact pathogenesis is still unknown, but several trigger factors in genetically predisposed individuals might initially lead to an immunologically triggered release of pro-inflammatory cytokines, resulting in a profound dysregulation of the connective tissue metabolism and ultimately to induction of fibrosis. To date, there are no specific serological markers available for localized scleroderma. Within the last years, several validated clinical scores have been introduced as potential outcome measures for the disease. Given the rarity of localized scleroderma, only few evidence-based therapeutical treatment options exist. So far, the most robust data is available for ultraviolet A1 phototherapy in disease that is restricted to the skin, and methotrexate alone or in combination with systemic corticosteroids in more severe disease that additionally affects extracutaneous structures. This practical review summarizes relevant information on the epidemiology, pathogenesis, clinical subtypes and classifications, differential diagnoses, clinical scores and outcome measures, and current treatment strategies of localized scleroderma.
