Abstract
The pathogenesis of immunoinflammatory rheumatic diseases (IRDs) is based on chronic inflammation, one of the key mechanisms of which may be abnormal activation of macrophages, leading to further disruption of the immune system. OBJECTIVE . The objective of this study was to evaluate the proinflammatory activation of circulating monocytes in patients with IRDs. MATERIALS AND METHODS . The study involved 149 participants (53 patients with rheumatoid arthritis (RA), 45 patients with systemic lupus erythematosus (SLE), 34 patients with systemic scleroderma (SSc), and 17 participants without IRDs) 30 to 65 years old. Basal and lipopolysaccharide (LPS)-stimulated secretion of monocytes was studied in a primary culture of monocytes obtained from blood by immunomagnetic separation. Quantitative assessment of the cytokines tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), as well as the chemokine monocyte chemoattractant protein-1 (MCP-1) was carried out in the culture fluid by ELISA. Proinflammatory activation of monocytes was calculated as the ratio of LPS-stimulated and basal secretions. RESULTS . It was shown that the basal secretion of all studied cytokines was significantly increased in all groups of patients with IRDs, except for the secretion of IL-1β in the SLE group, compared to the control. LPS-stimulated secretion of TNF-α was increased and MCP-1 was decreased in patients with IRDs compared to the control group; LPS-stimulated IL-1β secretion only in the SSc group significantly differed from the control group. In the RA group, monocyte activation was reduced for all cytokines compared to the control; in the SLE group, for TNF-α and MCP-1; in the SSc group, for MCP-1. CONCLUSIONS . The decrease in proinflammatory activation of monocytes in patients with IRDs is due to a high level of basal secretion of cytokines, which can lead to disruption of the adequate immune response in these diseases and is an important link in the pathogenesis of chronic inflammation.

Abstract
SSc-ILD (scleroderma associated interstitial lung disease) is a complex rheumatic disease characterized in part by immune dysregulation leading to the progressive fibrotic replacement of normal lung architecture. Because improved treatment options are sorely needed, additional study of the fibroproliferative mechanisms mediating this disease has the potential to accelerate development of novel therapies. The contribution of innate immunity is an emerging area of investigation in SSc-ILD as recent work has demonstrated the mechanistic and clinical significance of the NLRP3 inflammasome and its associated cytokines of TNFα (tumor necrosis factor alpha), IL-1β (interleukin-1 beta), and IL-18 in this disease. In this review, we will highlight novel pathophysiologic insights afforded by these studies and the potential of leveraging this complex biology for clinical benefit.

Abstract
Dermal white adipose tissue (dWAT) is a dynamic component of the skin and closely interacts with the hair follicle. Interestingly, dWAT envelops the hair follicle during anagen and undergoes fluctuations in volume throughout the hair cycle. dWAT-derived extracellular vesicles can significantly regulate the hair cycle, and this provides a theoretical basis for utilizing adipose tissue as a feasible clinical strategy to treat hair loss. However, the amount and depth of the available literature are far from enough to fully elucidate the prominent role of dWAT in modulating the hair growth cycle. This review starts by investigating the hair cycle-coupled dWAT remodeling and the reciprocal signaling interplay underneath. Then, it summarizes the current literature and assesses the advantages and limitations of clinical research utilizing adipose-derived therapies for hair regeneration.

Abstract
Background Systemic sclerosis (SSc) is an autoimmune connective tissue disease that affects multiple organs, leading to elevated morbidity and mortality with limited treatment options. The early detection of organ involvement is challenging as there is currently no serum marker available to predict the progression of SSc. The aptamer technology proteomic analysis holds the potential to correlate SSc manifestations with serum proteins up to femtomolar concentrations. Methods This is a two-tier study of serum samples from women with SSc (including patients with interstitial lung disease - ILD - at high-resolution CT scan) and age-matched healthy controls (HC) that were first analyzed with aptamer-based proteomic analysis for over 1300 proteins. Proposed associated proteins were validated by ELISA first in an independent cohort of patients with SSc and HC, and selected proteins subject to further validation in two additional cohorts. Results The preliminary aptamer-based proteomic analysis identified 33 proteins with significantly different concentrations in SSc compared to HC sera and 9 associated with SSc-ILD, including proteins involved in extracellular matrix formation and cell-cell adhesion, angiogenesis, leukocyte recruitment, activation, and signaling. Further validations in independent cohorts ultimately confirmed the association of specific proteins with early SSc onset, specific organ involvement, and serum autoantibodies. Conclusions Our multi-tier proteomic analysis identified serum proteins discriminating patients with SSc and HC or associated with different SSc subsets, disease duration, and manifestations, including ILD, skin involvement, esophageal disease, and autoantibodies.

Abstract
BACKGROUND Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) are the most eminent forms of pulmonary involvement in Scleroderma. In this study we investigate the interaction between cytokines and apoptotic proteins in treatment naive Scleroderma (SSc) patients with and without pulmonary involvement. METHODS Newly diagnosed treatment naïve Scleroderma (SSc) patients (n = 100) and healthy controls (n = 100) were enrolled. Patients were classified as ILD-SSc, PAH-SSc and non-pulmonary SSc (np-SSc). Study variables like mRSS score, autoantibody profile, serum cytokines, serum TGF-β (1,2,3) and apoptotic proteins were assessed for these patients. RESULTS Scleroderma patients showed elevated levels of serum cytokines, but significantly lower IL-22 and TGF- β1 when compared to healthy controls (p < 0.05). Apoptotic proteins were significantly elevated among Scleroderma patients, but the patient groups also showed significant lower caspase 1/3/9 levels when compared to healthy controls (p < 0.05). ILD-SSc patients reported higher mRSS score (p = 0.0436) when compared with PAH-SSc and np-SSc. In ILD-SSc patients, finger tightening (p = 0.0481) and calcinosis/lesions (p = 0.0481) were significant clinical presentations whereas, digital ulcers were significantly prominent in np-SSc patients (p = 0.0132). Elevated TGF-β3 levels (p = 0.02) in SSC-ILD and reduced IL-4 levels (p = 0.02) in SSC-PAH were significant cytokines as compared to np-SSc. Significant correlations were obtained among serum cytokines and apoptotic proteins in Scleroderma patients with and without pulmonary involvement. (p < 0.05) CONCLUSION: Our study highlights the correlation between mRSS score, cytokines and apoptotic proteins in SSc patients with pulmonary involvement. A longitudinal follow up in these patients with assessment of these immunological parameters may be helpful in monitoring the disease.

Abstract
Systemic sclerosis (SSc, scleroderma) is a multifaceted rare connective tissue disease whose pathogenesis is dominated by immune dysregulation, small vessel vasculopathy, impaired angiogenesis, and both cutaneous and visceral fibrosis. Microvascular impairment represents the initial event of the disease, preceding fibrosis by months or years and accounting for the main disabling and/or life-threatening clinical manifestations, including telangiectasias, pitting scars, periungual microvascular abnormalities (e.g., giant capillaries, hemorrhages, avascular areas, ramified/bushy capillaries) clinically detectable by nailfold videocapillaroscopy, ischemic digital ulcers, pulmonary arterial hypertension, and scleroderma renal crisis. Despite a variety of available treatment options, treatment of SSc-related vascular disease remains problematic, even considering SSc etherogenity and the quite narrow therapeutic window. In this context, plenty of studies have highlighted the great usefulness in clinical practice of vascular biomarkers allowing clinicians to assess the evolution of the pathological process affecting the vessels, as well as to predict the prognosis and the response to therapy. The current narrative review provides an up-to-date overview of the main candidate vascular biomarkers that have been proposed for SSc, focusing on their main reported associations with characteristic clinical vascular features of the disease.

Abstract
Systemic sclerosis is an autoimmune connective tissue disease characterized by vasculopathy and fibrosis of the skin and internal organs. The pathogenesis of systemic sclerosis is very complex. Mediators produced by immune cells are involved in the inflammatory processes occurring in the tissues. The currently available therapeutic options are often insufficient to halt disease progress. This article presents an overview of potential therapeutic targets and the pipeline of possible future therapeutic options. It is based on research of clinical trials involving novel, unestablished methods of treatment. Increasing knowledge of the processes and mediators involved in systemic scleroderma has led to the initiation of drug trials with therapeutic targets of CD28-CD80/86, CD19, CCL24, CD20, CD30, tumor necrosis factor (TNF), transforming growth factor β (TGF-β), B-cell activating factor (BAFF), lysophosphatidic acid receptor 1 (LPA1 receptor), soluble guanylate cyclase (sGC), Janus kinases (JAK), interleukin 6 (IL-6), endothelin receptor, and autotaxin. Data from clinical trials on these drugs indicate a significant potential for several new therapeutic options for systemic sclerosis in the upcoming future.

Abstract
Systemic sclerosis (SSc) is a connective tissue disease that often causes pulmonary fibrosis. Dipeptidyl peptidase 4 (DPP4) inhibitor has shown anti-fibrotic properties in various fibrotic diseases. However, only two studies have reported its anti-fibrosis effects in pulmonary fibrosis, and the mechanism is not completely clear. In the present study, we further investigated the protective effects of linagliptin, a highly specific DPP4 inhibitor, on pulmonary fibrosis in SSc mouse model and the potential mechanisms. The results showed that linagliptin ameliorated pulmonary fibrosis in SSc mouse model, as evidenced by improved pathological changes of lung and body weight loss induced by BLM. Linagliptin also reduced BLM-induced oxidative stress, inflammation in lung in vivo. We revealed that linagliptin attenuated BLM-induced endothelial-to-mesenchymal transition (EndMT) in vitro and in vivo. BLM-induced enhanced migration ability of endothelial cells was also alleviated by linagliptin. Moreover, we confirmed that the Akt/mammalian target of rapamycin pathway was involved in BLM-induced EndMT in vivo, which was suppressed by linagliptin. In summary, we further confirmed the therapeutic effects of linagliptin on pulmonary fibrosis in SSc mouse model, which is based on its inhibitory effects on EndMT, oxidative stress, and inflammation.

Abstract
Systemic sclerosis (SSc) is a chronic connective tissue disorder characterized by immune dysregulation, chronic inflammation, vascular endothelial cell dysfunction, and progressive tissue fibrosis of the skin and internal organs. Moreover, increased cancer incidence and accelerated aging are also found. The increased cancer incidence is believed to be a result of chromosome instability. Accelerated cellular senescence has been confirmed by the shortening of telomere length due to increased DNA breakage, abnormal DNA repair response, and telomerase deficiency mediated by enhanced oxidative/nitrative stresses. The immune dysfunctions of SSc patients are manifested by excessive production of proinflammatory cytokines IL-1, IL-6, IL-17, IFN-α, and TNF-α, which can elicit potent tissue inflammation followed by tissue fibrosis. Furthermore, a number of autoantibodies including anti-topoisomerase 1 (anti-TOPO-1), anti-centromere (ACA or anti-CENP-B), anti-RNA polymerase enzyme (anti-RNAP III), anti-ribonuclear proteins (anti-U1, U2, and U11/U12 RNP), anti-nucleolar antigens (anti-Th/T0, anti-NOR90, anti-Ku, anti-RuvBL1/2, and anti-PM/Scl), and anti-telomere-associated proteins were also found. Based on these data, inflamm-aging caused by immune dysfunction-mediated inflammation exists in patients with SSc. Hence, increased cellular senescence is elicited by the interactions among excessive oxidative stress, pro-inflammatory cytokines, and autoantibodies. In the present review, we will discuss in detail the molecular basis of chromosome instability, increased oxidative stress, and functional adaptation by deranged immunome, which are related to inflamm-aging in patients with SSc.

Abstract
Body fat has regulatory functions through producing cytokines and adipokines whose role in the pathogenesis of systemic sclerosis (SSc) is currently emerging. Changes in body mass, either over‐ or underweight, entail a dysregulation of the cytokine/adipokine network that may impact upon SSc disease activity. We evaluated serum levels of adipokines and cytokines in SSc patients and correlated them to clinical features and body mass index (BMI) categories. The study included 89 SSc patients and 26 healthy donors (HD). Serum levels of adiponectin, leptin, resistin, visfatin, tumor necrosis factor (TNF)‐α, interferon (IFN)‐γ, interleukin (IL)‐2, IL‐10 and IL‐17A were measured by multiplex immunoassay and correlated to BMI and disease‐specific features. Student’s t‐test or analysis of variance (ANOVA) were used for comparisons between groups. Spearman’s or Pearson’s tests were used for correlation analysis. Serum levels of TNF‐α, IL‐2, leptin and resistin were significantly higher in SSc than in HD. Leptin levels were significantly higher in interstitial lung disease (ILD)‐ and pulmonary arterial hypertension (PAH)‐SSc subgroups. The highest levels of IL‐17A, IL‐2, IL‐10, leptin and visfatin were detected in SSc patients with obesity (p < 0.01). Conversely, underweight SSc patients showed the highest TNF‐α levels (p < 0.05). Adipokines, IL‐2, IL‐10 and IL‐17A were found to be increased in SSc patients with obesity, but whether or not they play a role in the pathogenesis of the disease remains to be investigated. Intriguingly, underweight patients had the highest TNF‐α levels, suggesting a potential role of TNF‐α in inducing the cachexia observed in long‐lasting disease.

Birlutiu V, Boicean LC. Serum leptin level as a diagnostic and prognostic marker in infectious diseases and sepsis: A comprehensive literature review. Medicine (Baltimore) 2021; 100:e25720. [PMID: 33907162 PMCID: PMC8084034 DOI: 10.1097/md.0000000000025720] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 02/27/2021] [Accepted: 04/11/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Infections and sepsis are common causes of morbidity and mortality, with an increasing incidence worldwide. Leptin is involved in the inflammatory process and may modulate the cytokine production, immune cell proliferation and endothelial function. There are conflicting results regarding alterations of leptin levels in infectious diseases and the outcome from sepsis.The aim of the current article is to provide an overview of the medical literature on the correlations between variations of leptin levels and infectious diseases and sepsis. METHODS We performed an extensive literature search in PubMed and Google Scholar databases, using keywords to identify articles related to leptin in infectious diseases and sepsis. Searches were referenced using medical subject headings that included "leptin," "adipokines," "sepsis," "infectious diseases," "leptin deficiency," "leptin resistance" or "hyperleptinemia." The language of publication, journal, or country were not included as limitation criteria.Articles or abstracts containing adequate information, such as age, sex, anthropometric indices, clinical presentation, comorbidities, and management were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We assessed the quality of the studies selected.The final review of all databases was conducted on June 18, 2020. RESULTS We find the results from the current review to be of great importance due to the possible therapeutic role of leptin analogs in states of leptin deficiency associated with infectious diseases or sepsis.In hyperleptinemia, a therapeutic plan for obtaining leptin neutralization also needs further investigations. This could lead to the reduction of proinflammatory responses.There is a need for further studies to demonstrate the specificity and sensitivity of leptin in the early diagnosis of sepsis and the need to measure serum leptin levels in routine evaluation of the critical patient. CONCLUSION The multiple effects of leptin are of growing interest, but further studies are needed to elucidate the role of leptin signalling in infectious diseases and sepsis. Because very few human studies are reported, we recommend the need for further research.Better understanding of the pathophysiology of sepsis and the implication of circulating total leptin in this process could help physicians in managing this life-threatening condition.

Serum vasohibin-1 levels: A potential marker of dermal and pulmonary fibrosis in systemic sclerosis. Exp Dermatol 2021; 30:951-958. [PMID: 33682189 DOI: 10.1111/exd.14321] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 03/01/2021] [Accepted: 03/02/2021] [Indexed: 12/23/2022]
Abstract
Vasohibin-1 (VASH-1) is a potent anti-angiogenic factor mainly produced by endothelial cells. In addition, VASH-1 prevents TGF-β-dependent activation of renal fibroblasts. Since systemic sclerosis (SSc) is an autoimmune disease characterized by vasculopathy and fibrosis of multiple organs, VASH-1 may be involved in the development of this disease. In this study, we investigated the potential role of VASH-1 in SSc by evaluating the clinical correlation between serum VASH-1 levels and the expression of VASH-1 in SSc-involved skin. Serum VASH-1 levels were higher in SSc patients, especially those with diffuse cutaneous involvement, than in healthy controls and positively correlated with skin score. Furthermore, SSc patients with interstitial lung disease had significantly elevated levels of serum VASH-1 as compared to those without. Importantly, serum VASH-1 levels correlated inversely with both the percentage of predicted vital capacity and the percentage of predicted diffusion lung capacity for carbon monoxide and positively with serum KL-6 levels, but not serum surfactant protein D levels. In SSc-involved skin, VASH1 mRNA was remarkably upregulated compared with healthy control skin, but the major source of VASH-1 was not clear. Fli1 deficiency, a predisposing factor inducing SSc-like endothelial properties, did not affect VASH-1 expression in human dermal microvascular endothelial cells. Collectively, these results suggest that VASH-1 upregulation in the skin and sera is linked to dermal and pulmonary fibrotic changes in SSc, while the contribution of VASH-1 to SSc vasculopathy seems to be limited.

Abstract
It is an indisputable fact that obesity is associated with a series of health problems. One important hallmark of obesity is excessive accumulation of lipids in the adipocyte, especially triglyceride (TG). Currently, the adipocyte has been considered not only as a huge repository of excess energy in the form of fat but also as an important source of multiple hormones and cytokines called adipokines. In obesity, the adipocyte is dysfunctional with excessive production and secretion of pro-inflammatory adipokines, such as tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), and leptin. On the other hand, accumulating evidence has shown that leptin plays a vital role in stimulating angiogenesis, controlling lipid metabolism, and modulating the production of pro-inflammatory cytokines. Furthermore, the various activities of leptin are related to the wide distribution of leptin receptors. Notably, it has been reported that enhanced leptin levels and dysfunction of the leptin signaling pathway can influence diverse skin diseases. Recently, several studies revealed the roles of leptin in wound healing, the hair cycle, and the pathogenic development of skin diseases, such as psoriasis, lupus erythematosus, and dermatological cancers. However, the exact mechanisms of leptin in modulating the dermatological diseases are still under investigation. Therefore, in the present review, we summarized the regulatory roles of leptin in the pathological progression of diverse diseases of skin and skin appendages. Furthermore, we also provided evidence to elucidate the complicated relationship between leptin and different dermatological diseases, such as systemic lupus erythematosus (SLE), psoriasis, hidradenitis suppurativa, and some skin tumors.

Abstract
Systemic sclerosis (SSc) is a chronic autoimmune connective tissue disease with manifestations in multiple organs, including the skin, lung, heart, joints, gastrointestinal tract, kidney, and liver. Its pathophysiology is characterized by inflammation, fibrosis, and vascular damage, with an increased expression of numerous cytokines, chemokines, and growth factors. However, besides these growth factors and cytokines, another group of molecules may be involved in the pathogenesis of SSc: the adipokines. Adipokines are proteins with metabolic and cytokine-like properties, which were originally found to be expressed by adipose tissue. However, their expression is not limited to this tissue, and they can also be found in other organs. Therefore, this review will describe the current knowledge regarding adipokines in the context of SSc and try to elucidate their potential role in the pathogenesis of SSc.

Evidence of a Relationship Between Plasma Leptin, Not Nesfatin-1, and Craving in Male Alcohol-Dependent Patients After Abstinence. Front Endocrinol (Lausanne) 2020; 11:159.

Abstract
The goal of this study was to determine whether the plasma leptin, nesfatin-1, cortisol, brain-derived neurotrophic factor (BDNF), and inflammatory cytokines could be used as potential biomarkers for the degree of craving in the alcohol-dependent patients after 1 month of abstinence. A total of 83 patients with alcohol use disorder (AUD) and 61 healthy subjects were assessed. Patients with AUD were selected from Department of Material Dependence, Anhui Mental Health Center, and subjects in the control group were selected from healthy volunteers. The Alcohol Urge questionnaire Scale (AUQ) was used to evaluate the extent of craving for alcohol, and the Michigan Alcoholism Screening Test (MAST), the Fagerstrom Test for Nicotine Dependence (FTND), the Self-Rating Anxiety Scale (SAS), and the Self-Rating Depression Scale (SDS) were also assessed in patients with AUD. Enzyme-Linked Immunosorbent Assay (ELISA) was used for the measurement of plasma leptin, nesfatin-1, cortisol, BDNF, Interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor-α (TNF-α) levels. Compare with healthy controls, the average leptin, leptin/BMI, IL-6, CRP, and TNF-α levels in patients with AUD were significantly increased, while the BDNF levels were significantly decreased. Moreover, the partial correlational analysis showed that the AUQ scores of the alcohol-dependent patients were positively correlated with the plasma leptin levels (r = 0.613, P < 0.001), rather than nesfatin-1 (r = 0.066, P = 0.569) after controlling for age as covariate. Furthermore, plasma nesfatin-1 levels were found to be correlated with the SDS scores (r = 0.366, P = 0.001) in the AUD group. In addition, plasma leptin levels were positively associated with the plasma IL-6 (r = 0.257, P = 0.033), CRP (r = 0.305, P = 0.011), and TNF-α (r = 0.311, P = 0.009) levels, and negatively associated with the BDNF levels (r = -0.245, P = 0.042) in patients with AUD. These results suggest that plasma leptin, but not nesfatin-1, might be a potential biomarker for the degree of craving in alcohol-dependent patients after 1 month of abstinence, the mechanism of which might be related to the dysfunction of the inflammatory cytokines and BDNF levels.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disease with high mortality, characterized by chronic inflammation and fibrosis, which are processes associated with higher serum tumor necrosis factor-α (sTNF-α) levels. TNFA -308G>A and -238G>A polymorphisms have been associated with higher sTNF-α levels. In this study, we genotyped the TNFA -308G>A and -238G>A polymorphisms in 53 SSc patients and 115 unrelated control subjects (CS) from southern Mexico. The TNFA mRNA expression and sTNF-α levels were also quantified by qPCR and enzyme-linked immunosorbent assays, respectively. TNFA -308GA genotype was associated with disease susceptibility according to a codominant genetic model (OR = 3.2, 95% CI 1.05-9.75, p = 0.03), and with higher anti-fibrillarin antibodies (p = 0.01), and higher skin thickening (p = 0.006). TNFA -238GA was not associated with SSc risk. TNFA mRNA expression and sTNF-α levels were similar between SSc patients and CS and were not statistically associated with the TNFA polymorphisms; however, a correlation (rho = 0.362, p = 0.009) between sTNF-α levels with anti-RNA polymerase III antibodies was observed in the SSc patients. In conclusion, the -308G>A polymorphism is a genetic marker of SSc susceptibility in population from southern Mexico, and it is associated with skin thickening and anti-fibrillarin antibodies. In addition, sTNF-α levels correlate positively with the anti-RNA pol III antibodies levels.

Abstract
INTRODUCTION Leptin and adiponectin have recently received the attention of researchers as attractive biomarkers in systemic sclerosis (SSc) because of their role in the inflammatory process, vascular function and fibrosis. We hypothesized that leptin and adiponectin may be associated with disease activity and severity in patients with SSc. AIM To compare serum leptin, adiponectin and leptin/adiponectin levels in patients with SSc and healthy controls and to evaluate their possible relationship with frequently used laboratory markers and clinical findings. MATERIAL AND METHODS The study included 48 Caucasian female patients with SSc and 38 healthy controls. Serum concentrations of leptin and adiponectin were measured in patients and controls using commercially available ELISA Kits (Quantikine ELISA Kit R&D Systems, Minneapolis, MN, USA). The results were assessed by the Mann-Whitney U-test and Spearman's correlation test. RESULTS Leptin and adiponectin levels correlated with body mas index in SSc patients (r = 0.495, p = 0.000398 and r = -0.306; p = 0.0342) in contrast to healthy controls (p = 0.070 and p = 0.256, respectively), and, in SSc patients only, a strong negative correlation was observed between leptin and adiponectin serum levels (r = -0.314; p = 0.0312). Diffuse form of the disease (dcSSc) was associated with significantly lower serum adiponectin levels (8638.62 ±10382.62). Active disease was associated with significantly lower leptin concentration (13700.49 ±18293.32) and there was a significant negative correlation between leptin serum level and activity index score (r = -0.342; p = 0.0185). CONCLUSIONS The results of our study indicate that leptin levels might correlate with disease activity and subtype in SSc patients.

Abstract
Cognitive changes are common in patients with active cancer and during its remission. This has largely been blamed on therapy-related toxicities and diagnosis-related stress, with little attention paid to the biological impact of cancer itself. A plethora of clinical studies demonstrates that cancer patients experience cognitive impairment during and after treatment. However, recent studies show that a significant portion of patients with non-central nervous system (CNS) tumors experience cognitive decline prior to treatment, suggesting a role for tumor-derived factors in modulating cognition and behavior. Cancer-related cognitive impairment (CRCI) negatively impacts a patient’s quality of life, reduces occupational and social functioning, and increases morbidity and mortality. Furthermore, patients with cancer cachexia frequently experience a stark neurocognitive decline, suggesting peripheral tumors exert an enduring toll on the brain during this chronic paraneoplastic syndrome. However, the scarcity of research on cognitive impairment in non-CNS cancers makes it difficult to isolate psychosocial, genetic, behavioral, and pathophysiological factors in CRCI. Furthermore, clinical models of CRCI are frequently confounded by complicated drug regimens that inherently affect neurocognitive processes. The severity of CRCI varies considerably amongst patients and highlights its multifactorial nature. Untangling the biological aspects of CRCI from genetic, psychosocial, and behavioral factors is non-trivial, yet vital in understanding the pathogenesis of CRCI and discovering means for therapeutic intervention. Recent evidence demonstrating the ability of peripheral tumors to alter CNS pathways in murine models is compelling, and it allows researchers to isolate the underlying biological mechanisms from the confounding psychosocial stressors found in the clinic. This review summarizes the state of the science of CRCI independent of treatment and focuses on biological mechanisms in which peripheral cancers modulate the CNS.

Abstract
Systemic sclerosis is a multiorgan autoimmune disease characterized by vasculopathy and tissue fibrosis of unknown etiology. Recently, adipokines (cell signaling proteins secreted by adipose tissue) have attracted much attention as a cytokine family contributing to the various pathological processes of systemic sclerosis. Adipokines, such as leptin, adiponectin, resistin, adipsin, visfatin or chemerin are a heterogenic group of molecules. Adiponectin exhibits anti-fibrotic features and affects inflammatory reactions. Leptin promotes fibrosis and inflammation. Resistin was linked to vascular involvement in systemic sclerosis. Visfatin was associated with regression of skin lesions in late-stage systemic sclerosis. Chemerin appears as a marker of increased risk of impaired renal function and development of skin sclerosis in the early stage of systemic sclerosis. Vaspin was indicated to have a protective role in digital ulcers development. Novel adipokines-adipsin, apelin, omentin and CTRP-3-are emerging as molecules potentially involved in SSc pathogenesis. Serum adipokine levels may be used as predictive and diagnostic factors in systemic sclerosis. However, further investigations are required to establish firm correlations between distinct adipokines and systemic sclerosis.

Adipokine expression in systemic sclerosis lung and gastrointestinal organ involvement. Cytokine 2019; 117:41-49. [PMID: 30784899 DOI: 10.1016/j.cyto.2018.11.013] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 10/12/2018] [Accepted: 11/12/2018] [Indexed: 12/12/2022]
Abstract
OBJECTIVES The immunomodulatory properties of adipokines have previously been reported in autoimmune disorders. Less is known about the role of adipokines in systemic sclerosis (SSc). Lung and gastrointestinal tract are frequently involved in SSc; therefore, these organs were analyzed for adipokine expression as well as pulmonary samples of patients suffering from idiopathic pulmonary fibrosis (IPF) as comparison. METHODS Gastric samples (antrum, corpus) of SSc were analyzed immunohistochemically for adiponectin, resistin and visfatin compared with non-SSc related gastritis. Inflammatory cells were quantified in gastric samples and correlated with adipokine expression. Lung samples of SSc, IPF and healthy controls were also analyzed. Protein levels of lung tissue lysates and bronchoalveolar lavages (BAL) in minor fibrotic stages were measured by ELISA. RESULTS Lung sections of donor parenchyma showed significantly stronger adiponectin signals as IPF and SSc (donor vs. IPF: p < 0.0001). In SSc and IPF, resistin and visfatin were increased within immune cell infiltrates, but overall no difference in expression for resistin or visfatin compared to controls was observed. In BAL and lung protein lysates of early stages of fibrosis, adiponectin and visfatin were not reduced in IPF and SSc compared to controls. In gastric samples collected by standard endoscopic gastric biopsy, adiponectin was also significantly reduced in SSc- compared to non-SSc gastritis (p = 0.049) while resistin and visfatin were comparable although deeper fibrotic layers were not included in the respective samples. Adiponectin-positive tissues showed higher amounts of CD4+ but not CD8+ T cells. Controls showed no correlation between CD4+ T cells and resistin, whereas SSc showed significantly more CD4+ T cells in resistin-negative tissues. CONCLUSION Adipokines are expressed in gastric and lung samples of patients with SSc and in lung samples affected by IPF. Prominently, adiponectin levels were reduced in fibrotic SSc gastritic tissue as well as in IPF and SSc lung tissue. Consequently, adiponectin expression seems to be associated with fibrotic progression in the context of SSc and IPF.

Abstract
OBJECTIVE We aimed to evaluate the relationship between circulating blood adipokine levels and systemic sclerosis (SSc). METHODS We conducted a meta-analysis on serum/plasma adiponectin, leptin, or resistin levels in patients with SSc and controls, and performed a subgroup analysis based on ethnicity and/or disease type. RESULTS Eleven studies (511 patients with SSc and 341 controls) were included in the meta-analysis. Meta-analysis revealed that adiponectin levels were significantly lower in patients with SSc than in controls (standardized mean differences [SMD] = -0.638; 95 % confidence intervals [CI] = -1.154, -0.122; P = 0.015). Stratification by ethnicity showed a low adiponectin level associated with SSc in Caucasians (SMD = -0.439; 95 % CI = -1.092, -0.213; P = 0.187) and Asians (SMD = -1.006; 95 % CI = -2.031, -0.019; P = 0.055), although this result was not statistically significant. Stratification by disease type revealed that the adiponectin level was significantly lower in the diffuse SSc, but not limited SSc, group than in the control (diffuse: SMD = -1.445; 95 % CI = -2.276, -0.614; P = 0.001; limited: SMD = 0.188; 95 % CI = -0.064, 0.439; P = 0.144). Meta-analysis showed no association between leptin levels and SSc (SMD = -0.029; 95 % CI = -1.362, 1.304; P = 0.966), and no association between resistin levels and SSc (SMD = 0.202; 95 % CI = -0.091, 0.496; P = 0.177). CONCLUSIONS Our meta-analysis revealed a significantly lower circulating adiponectin level in patients with SSc than in controls. This difference was apparent in the diffuse type of SSc, but not in the limited type. However, circulating leptin and resistin levels were not different between patients with SSc and healthy controls.

Abstract
NEW FINDINGS What is the central question of this study? Do systemic sclerosis patients exhibit impaired nitric oxide-mediated vascular function of the lower limb and are these decrements correlated with plasma biomarkers for inflammation and oxidative stress? What is the main finding and its importance? Findings indicate impaired nitric oxide-mediated vascular function, linked to the incidence of digital ulcers and a milieu of inflammation and oxidative stress. However, the absence of significant correlations between individual biomarkers and blood flow responses suggests that the vasculopathy observed in systemic sclerosis may not be solely the result of derangements in the redox balance or inflammatory signalling. ABSTRACT Systemic sclerosis (SSc) is an autoimmune disease characterized by vasculopathy, which may be the consequence of inflammation and oxidative stress that ultimately leads to a reduced nitric oxide (NO) bioavailability. Passive leg movement (PLM) is a novel methodology for assessing lower limb vascular function that is predominantly NO dependent. We combined this vascular assessment with a comprehensive panel of plasma biomarkers to assess the axis of inflammation, oxidative stress and NO in SSc patients (n = 12; 62 ± 11 years of age) compared with healthy control subjects (n = 17; 60 ± 16 years of age). The PLM-induced changes in leg blood flow (LBF; 191 ± 104 versus 327 ± 217 ml min-1 ) and LBF area under the curve (39 ± 104 versus 125 ± 131 ml) were reduced in SSc compared with control subjects. Stratification of patients according to history of digital ulcer (DU) formation revealed a further reduction in LBF area under the curve in DU (-13 ± 83 ml) versus non-DU (91 ± 102 ml) patients. Biomarkers of inflammation (C-reactive protein) and oxidative stress (malondialdehyde and protein carbonyl) were all elevated in SSc (C-reactive protein, 3299 ± 2372 versus 984 ± 565 ng ml-1 ; malondialdehyde, 3.2 ± 1.1 versus 1.1 ± 0.7 μm; and protein carbonyl, 0.15 ± 0.05 versus 0.12 ± 0.03 nmol mg-1 ), and C-reactive protein was further elevated in patients with a history of DU (4551 ± 2752 versus 2047 ± 1019 ng ml-1 ) compared with non-DU, although these were not individually correlated with changes in LBF. These findings of impaired NO-mediated vascular function, linked to DU and a milieu of inflammation and oxidative stress, suggest that redox balance plays an important, but not necessarily deterministic, role in the vascular pathophysiology of SSc.

Abstract
Introduction: Pericardial effusion is a common manifestation of systemic sclerosis, but its pathogenesis has been poorly investigated. Adipokines and interleukins may play a role in the pathophysiology of pericardial effusion. This study aimed at evaluating serum levels of adipokines and interleukins in systemic sclerosis patients with and without pericardial effusion. Methods: A total of 87 systemic sclerosis patients (age 52.6 ± 14 years; disease duration 8.2 ± 6.7 years) were recruited in this study. Demographics, body mass index, and clinical characteristics were recorded in each patient. Pericardial effusion was considered pathologic when ≥50 mL was detected by echocardiography. Serum levels of adiponectin, leptin, resistin, visfatin, tumor necrosis factor-α, interferon-γ, interlueukin-2, interlueukin-10, and interlueukin-17 were measured using Multiplex Immunoassay (Bioplex 200 System). Results: In all, 11 (13%) systemic sclerosis patients had pericardial effusion. Systemic sclerosis patients with and without pericardial effusion did not differ in age, sex, and body mass index. Systemic sclerosis patients with pericardial effusion had significantly higher levels of visfatin (median/interquartile range: 1546 pg/mL (interquartile range: 8590) vs 388 pg/mL (interquartile range: 103), p = 0.03) and interlueukin-17 (1.33 pg/mL (interquartile range: 3.5) vs 0.05 pg/mL (interquartile range: 0.56), p = 0.04), but lower levels of adiponectin (2,845,000 pg/mL (interquartile range: 4,132,900) vs 5,272,100 pg/mL (interquartile range 8,243,600), p = 0.02) than patients without pericardial effusion. Interstitial lung disease, pulmonary arterial hypertension, and “limited” or “diffuse” cutaneous subset did not correlate to adipokines or interleukin levels. Conclusion: Visfatin and adiponectin may play an important role in the pathogenesis of systemic sclerosis–related pericardial effusion. Further longitudinal studies are needed to unravel a possible role of these molecules as biomarkers of pericardial effusion in systemic sclerosis patients.

Abstract
Atopic dermatitis (AD) is a chronic, relapsing, and inflammatory skin disorder. It is characterized by an inappropriate skin barrier function, allergen sensitization, and recurrent skin infections. Resistin is an adipokine expressed mainly in macrophages and monocytes; it has a role in the inflammatory process and is associated with multiple inflammatory human diseases; however, only few studies linked resistin to atopic dermatitis. This study tested the association between G>A (rs3745367) and C>T (rs3219177) single nucleotide polymorphisms (SNPs) of the RETN gene with atopic dermatitis. In addition, it explored the relationship between serum resistin protein and atopic dermatitis. To achieve objectives of this study, 162 atopic dermatitis patients and 161 healthy participants were recruited in the study. A significant association was detected between rs3745367 and atopic dermatitis with age and gender specificity (p < 0.05), while no significant association between rs3219177 and atopic dermatitis was found (p > 0.05). For the serum resistin levels, a significant decrease was indicated in atopic dermatitis patients compared to healthy subjects (p < 0.05). In conclusion, rs3745367 may play a gender and age-specific role in atopic dermatitis. In addition, the significant decrease in the resistin protein level confirmed this association.

Abstract
RATIONALE Systemic Scleroderma (SSc) is a rare connective tissue disease clinically characterized by cutaneous sclerosis and variable systemic involvement. No drug is currently available to effectively reverse the fibrotic process in SSc. Previous reports have suggested that the tumor necrosis factor (TNF) antagonists could be useful for the treatment of fibrotic disorders. However, TNFα has long been considered as an antifibrotic cytokine. Whether TNF antagonist is effective for SSc patients needs to be tested. PATIENT CONCERNS-DIAGNOSIS Here we report a case with a 2-year history of SSc who was effectively treated with infliximab in our clinic. INTERVENTIONS The patient manifested skin thickening, chest tightness and arthralgia. Before admitted to our clinic, he was treated with methylprednisolone, prostacyclin, D-penicillamine and calcium antagonists but without significant improvement of his signs and symptoms. In our clinic, the patient was treated with infliximab. OUTCOMES His signs and symptoms were continued improving during the course of treatment. His skin biopsy showed significant reduction in fibroplasia finally. LESSONS TNF antagonist is an effective treatment for SSc.

Abstract
OBJECTIVE This study aimed to explore whether functional CYP2D6 polymorphisms are associated with susceptibility to autoimmune diseases. METHODS A meta-analysis was conducted on associations between autoimmune diseases and functional CYP2D6*4 1934 A/G and *3 polymorphisms and CYP2D6 phenotypes. RESULTS Twelve studies with 1,472 patients and 3,328 controls were included. Autoimmune disease and the CYP2D6 1934 A allele were significantly associated in the overall group, consistent with the Hardy-Weinberg equilibrium (OR = 1.227, 95% CI = 1.071-1.406, p = 0.003); stratification by ethnicity indicated that the CYP2D6 1934 A allele and autoimmune diseases were associated in Caucasians (OR = 1.225, 95% CI = 1.010-1.485, p = 0.039). The CYP2D6*3 allele was also associated with autoimmune diseases in Caucasians (OR = 1.977, 95% CI = 1.125-3.472, p = 0.018). Stratified by autoimmune disease type revealed that the CYP2D6 1934 AA genotype was associated with systemic lupus erythematosus (SLE; OR = 2.007, 95% CI = 1.170-3.442, p = 0.011) and ankylosing spondylitis (AS; OR = 2.317, 95% CI = 1.422-3.774, p = 0.001). The CYP2D6 PM+IM phenotype was significantly associated with autoimmune diseases in Caucasians (OR = 1.526, 95% CI = 1.038-2.246, p = 0.032) and with SLE (OR = 1.778, 95% CI = 1.249-2.532, p = 0.001). CONCLUSIONS This meta-analysis indicates that CYP2D6*4 and *3 polymorphisms and the CYP2D6 phenotype are associated with susceptibility to autoimmune diseases in Caucasians; particularly, the CYP2D6*4 polymorphism and CYP2D6 PM+IM phenotype are risk factors for SLE development.

Abstract
AIMS/INTRODUCTION The present study aimed to determine the associations between expressions of insulin-like growth factor-1 (IGF-1), tumor necrosis factor-α (TNF-α) and vascular endothelial growth factor 165 (VEGF165 ) in serum, and occurrence and development of type 2 diabetic nephropathy (DN). MATERIALS AND METHODS A total of 108 patients diagnosed as DN were randomly selected, including 50 patients in the microalbuminuria group, 44 patients in the macroalbuminuria group and 14 patients in the renal insufficiency group. Meanwhile, 97 healthy people were collected as a normal control group. Urinary albumin (UALB) and urine creatinine (Cr) of all participants were measured for 24 h, with their ratio (UALB/Cr) being calculated. Enzyme-linked immunosorbent assay was used to detect the serum concentrations of IGF-1, TNF-α and VEGF165 . RESULTS The expressions of serum IGF-1, TNF-α and VEGF165 in the type 2 DN patients were significantly higher than those in the control group (all P < 0.05). The expressions of serum IGF-1, TNF-α and VEGF165 in the type 2 DN patients were positively correlated with UALB/Cr (all P < 0.05). As type 2 DN worsened, the expressions of serum IGF-1, TNF-α and VEGF165 increased, and type 2 DN severity had positive correlations with serum IGF-1, TNF-α and VEGF165 concentrations (all P < 0.05). There was a positive association between IGF-1 and TNF-α, IGF-1 and VEGF165 , and TNF-α and VEGF165 (all P < 0.05). Logistic regression analysis showed that IGF-1 and VEGF165 were associated with the progression of DN (both P < 0.05). CONCLUSIONS Elevated expression levels of serum IGF-1, TNF-α and VEGF165 might exacerbate type 2 DN.

Abstract
BACKGROUND Systemic sclerosis is an chronic inflammatory autoimmune diseases. Adipokine has been reported to play an important role in modulating immune responses. Recent studies suggest that adipokine also plays some roles in the pathogenesis of systemic sclerosis (SSc). However, published data regarding the relationship between plasma/serum adipokine levels and SSc are contradictory. The aim of this study was at performing a meta-analysis to derive a more accurate estimation and further investigate the association of plasma/serum leptin and adiponectin levels with SSc patients. METHODS PubMed, and Web of Science databases (up to Feb 20, 2016) were used to obtain all relative published literatures. The study quality was assessed by the Newcastle-Ottawa scale. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by random-effect model analysis. RESULTS A total of fourteen studies were finally included in this meta-analysis. Among them, six of which were studied for the serum adiponectin levels in SSc patients, six of which were studied for the serum leptin levels in SSc patients, and two of them were studied both for serum adiponectin levels and serum leptin levels in SSc patients. The meta-analysis results showed that the serum adiponectin levels in SSc patients were significantly lower than that in normal controls (SMD = -0.608 ng/ml, 95% CI = -1.029 to -0.186, p = 0.005). However, there were no significant differences in serum leptin levels between SSc patients and healthy controls (SMD = -0.990 ng/ml, 95% CI = -2.340 to 0.359, p = 0.150). The subgroup analysis showed that Asia SSc patients with age less than 50 years old had lower plasma/serum adiponectin levels when compared with controls. CONCLUSION The serum adiponectin levels, but not serum leptin levels, in SSc patients were significantly lower than that in normal controls.

Abstract
Adropin, a secreted protein, is encoded by the energy homeostasis associated (ENHO) gene. It has been implicated in the several physiological and pathological processes such as angiogenesis and apoptosis. Therefore, the aim of present study was to investigate serum adropin levels and ENHO gene expressions in systemic sclerosis (SSc) characterized by vasculopathy, inflammation, and progressive fibrosis of the skin and internal organs. The study includes 27 patients with SSc, 39 patients with Behçet's disease (BD), and 20 healthy controls (HC). Serum adropin levels and ENHO gene expressions by peripheral blood mononuclear cells were analyzed by ELISA method and by real-time PCR, respectively. The serum adropin levels were higher in the SSc and BD groups than in the HC group (p = 0.023 and p < 0.001, respectively). However, there were no significant differences among the groups in terms of ENHO gene expressions (p ANOVA = 0.149). There was no significant difference between the limited and diffuse cutaneous subtypes of SSc in terms of serum adropin level and ENHO gene expression. Moreover, serum adropin level and ENHO gene expression were not associated with the disease activity and severity indexes. ENHO gene expression was correlated with the triglyceride levels in the BD group (r = -0.426, p = 0.027). The augmented serum adropin levels may be expected in the chronic inflammatory disease and seem not to be characteristic of only SSc. However, further studies are needed to explain the precise role of adropin in SSc.

Abstract
Osteoimmunology represents a large area of research resulting from the cross talk between bone and immune systems. Many cytokines and signaling cascades are involved in the field of osteoimmunology, originating from various cell types. The RANK/receptor activator of nuclear factor Kappa-B ligand (RANKL)/osteoprotegerin (OPG) signaling has a pivotal role in osteoimmunology, in addition to proinflammatory cytokines such as tumor necrosis factor-α, interleukin (IL)-1, IL-6, and IL-17. Clinically, osteoimmunological disorders, such as rheumatoid arthritis, osteoporosis, and periodontitis, should be classified according to their pattern of osteoimmunological serum biomarkers. Paget’s disease of bone is a common metabolic bone disorder, resulting from an excessively increased bone resorption coupled with aberrant bone formation. With the exception of the cellular responses to measles virus nucleocapsid protein and the interferon-gamma signature, the exact role of the immune system in Paget’s disease of bone is not well understood. The cytokine profiles, such as the increased levels of IL-6 and the interferon-gamma signature observed in this disease, are also very similar to those observed in other osteoimmunological disorders. As a potential osteoimmunological disorder, the treatment of Paget’s disease of bone may also benefit from progress made in targeted therapies, in particular for receptor activator of nuclear factor Kappa-B ligand and IL-6 signaling inhibition.

Adipokines influence the inflammatory balance in autoimmunity. Cytokine 2015; 75:272-9.

Abstract
Over the past few decades, our understanding of the role of adipose tissue has changed dramatically. Far from simply being a site of energy storage or a modulator of the endocrine system, adipose tissue has emerged as an important regulator of multiple important processes including inflammation. Adipokines are a diverse family of soluble mediators with a range of specific actions on the immune response. Autoimmune diseases are perpetuated by chronic inflammatory responses but the exact etiology of these diseases remains elusive. While researchers continue to investigate these causes, millions of people continue to suffer from chronic diseases. To this end, an increased interest has developed in the connection between adipose tissue-secreted proteins that influence inflammation and the onset and perpetuation of autoimmunity. This review will focus on recent advances in adipokine research with specific attention on a subset of adipokines that have been associated with autoimmune diseases.

Abstract
OBJECTIVE The aim of this paper is to review the anti-inflammatory cytokines IL-4 and IL-13 and their receptor signals; we discuss new insight into their possible roles in systemic sclerosis (SSc) and their overlapping function in SSc. INTRODUCTION SSc is a connective tissue disease characterized by fibrosis. The exact etiology of SSc is unknown, and no therapy has been proved effective in modifying its course. Recently the roles of IL-4 and IL-13 in the development of SSc have been extensively considered. The possible roles of IL-4 and IL-13, especially their overlapping function, in SSc are not well documented. METHODS A literature survey was performed using a PubMed database search to gather complete information regarding IL-4 and IL-13 and their role in inflammation. RESULTS AND CONCLUSIONS The participation of complex pathways of IL-4 and IL-13 in the process of inflammation and fibrosis action in SSc is still not very clear, and some pathogenesis of regulation found in vitro needs to be further proved. There is still more work which could be done to achieve useful developments with therapeutic benefit in SSc.

Abstract
Vaspin is an adipokine implicated in vascular inflammation and remodeling. We herein evaluated the clinical correlation of serum vaspin levels in systemic sclerosis (SSc). Consistent with previous reports, 12% of subjects exhibited serum vaspin levels over 10 ng/mL, likely due to genetic effects. Excluding these subjects, despite no difference between SSc and control subjects, serum vaspin levels were significantly decreased in SSc patients with digital ulcers compared with those without, suggesting the potential contribution of vaspin to digital ulcers of this disease.

Abstract
Previous research has shown inconsistent effect of systemic sclerosis (SSc) on bone mineral density (BMD). The objective of this study was to perform a meta-analysis of previous articles to investigate the differences in BMD (g/cm(2) ) between SSc and non-SSc populations and to discuss potential underlying mechanisms. Twelve full-text articles (including an outlier study and two studies with identical data) with 662 SSc patients and 886 controls were identified by searching Medline prior to 10 September, 2013 using search terms 'Systemic sclerosis' OR 'scleroderma' and 'osteoporosis' OR 'bone density' OR 'bone mass'. BMD (mean and standard deviation), T-scores and Z-scores at lumbar spine, femoral neck and total hip measured by dual-energy X-ray absorptiometry were extracted. Meta-analysis showed that a lower level of BMD was found in SSc patients, with weighted mean difference of -0.343 (95% CI: -0.500 to -0.186) at femoral neck, -0.084 (95% CI: -0.110 to -0.057) at total hip and -0.104 (95% CI: -0.135 to -0.073) at the lumbar spine. We conclude that patients with SSc may have a lower BMD level than healthy controls.

Abstract
Scleroderma is a systemic autoimmune disease of unknown etiology whose characteristic features include endothelial cell dysfunction, fibroblast proliferation, and immune dysregulation. Although almost any organ can be pathologically involved in scleroderma, lung complications including interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) are the leading cause of death in patients with this condition. Currently, the molecular mechanisms leading to development of scleroderma-related lung disease are poorly understood; however, the systemic nature of this condition has led many to implicate circulating factors in the pathogenesis of some of its organ impairment. In this article we focus on a new class of circulating factors derived from adipose-tissue called adipokines, which are known to be altered in scleroderma. Recently, the adipokines adiponectin and leptin have been found to regulate biological activity in endothelial, fibroblast, and immune cell types in lung and in many other tissues. The pleiotropic nature of these circulating factors and their functional activity on many cell types implicated in the pathogenesis of ILD and PAH suggest these hormones may be mechanistically involved in the onset and/or progression of scleroderma-related lung diseases.

Abstract
AIM The relationship between adiponectin, leptin, insulin-like growth factor-1 (IGF-1) and total lipid peroxide (TLP) concentrations, and its possible role in the development of diffuse cutaneous systemic sclerosis (dcSSc), were evaluated in this study. METHODS, RESULTS Plasma adipokines and IGF-1 levels were determined using the enzyme-linked immunosorbent assay method, whereas TLP levels were determined using a photometric test, in 36 dcSSc patients and 40 healthy controls matched by age, sex and body mass index (BMI). Plasma levels of adipokines were significantly lowered, while TLP and IGF-1 were increased in dcSSc patients compared to controls. Adiponectin correlated significantly with leptin (r = 0.44), TLP (r = -0.54), CRP (r = -0.47), erythrocyte sedimentation rate (ESR) (r = -0.40) and duration of disease (r = -0.44). A significant relationship was found between leptinemia and IGF-1 (r = -0.40), TLP (r = 0.44), duration of disease (r = -0.38) and BMI (r = 0.65). TLP correlated with IGF-1 (r = -0.43), C-reactive protein (r = 0.47), ESR (r = 0.49) and duration of disease (r = 0.46), while IGF-1 correlated with ESR (r = -0.40). CONCLUSIONS Adipose tissue may play a complex role in the development of dcSSc, affecting both the metabolic state of the organism, as well as free radical-induced connective tissue degradation. Although, leptin seems to exert a pro-oxidative effect and both adiponectin and IGF-1 appear to prevent free radical damage, confirmation of the above effects requires further research.

Abstract
To determine the relationship between serum leptin levels and disease activity in systemic sclerosis (SSc). A total of 60 subjects (30 controls and 30 patients) were included. The inflammatory markers and leptin levels were evaluated and body mass index (BMI) was measured for both groups. The assessment of the skin involvement was performed based on the modified Rodnan skin score (mRSS). Disease activity was evaluated according to the Valentini scleroderma disease activity index. There was a significant difference between the patient and control groups in terms of BMI (p < 0.05); however there was no difference with regards to age and gender (p > 0.05). Valentini scores and mRSS were determined to be significantly higher in active patients (n = 14) than in inactive patients (n = 16) (p < 0.05). No significant difference was determined between groups in terms of leptin levels (p > 0.05). However, leptin levels were significantly lower in active patients than in inactive patients (p < 0.05). We found a significant positive correlation between serum leptin and BMI (p < 0.05), and leptin and serum C3 levels (p < 0.05); no relationship was detected between leptin and other parameters. Leptin can be used as an activity marker in SSc. Further studies, including larger series, should be carried out to clarify this relationship.

Abstract
Both immune and non-immune mechanisms are involved in muscle damage and dysfunction occurring in idiopathic inflammatory myopathies (IIMs). Crosstalk among inflammatory cells, muscle and endothelial cells is essential in the pathogenesis of IIMs. Resistin, originally described as an adipokine linking obesity and insulin resistance in rodents, has been shown a pro-inflammatory molecule in humans. Besides its direct effect on production of several inflammatory mediators, resistin influences chemotaxis, migration, proliferation, cell survival, endothelial dysfunction and metabolism--all aspects implicated in the pathogenesis of IIMs. Up-regulation of resistin in muscle tissue and elevated serum resistin levels have been recently demonstrated in patients with IIMs. In addition, serum levels of resistin reflected global disease activity, including extramuscular organ involvement, in patients with this disease. However, there are currently not sufficient data to distinguish the features of resistin that cause injury of muscle tissue from those that promote muscle regeneration and repair. The aim of this review is therefore to summarize current knowledge about potential implication of resistin in idiopathic inflammatory myopathies.
