Abstract Systemic sclerosis (SSc) is a chronic connective tissue disease characterized by progressive fibrosis, vascular impairment and immune abnormalities. In recent years, adipokines (mediators synthetized by adipose tissue) have been indicated as a possible missing link in the pathogenesis of SSc. The aim of this study was to investigate the serum concentration of metabolic adipose tissue factors: adiponectin, resistin, leptin and endothelial proteins: endothelin-1, fractalkine and galectin-3 in patients with systemic sclerosis. The study included 100 patients with confirmed SSc diagnosis and 20 healthy individuals. The concentration of respective proteins was determined by enzyme-linked immunosorbent assay. The following markers showed statistically significant increased mean concentrations in patients with SSc in comparison to healthy control: resistin (13.41 vs 8.54 ng/mL; P = 0.0012), endothelin-1 (1.99 vs 1.31 pg/mL; P = 0.0072) and fractalkine (2.93 vs 1.68 ng/mL; P = 0.0007). Elevated serum levels of galectin-3 (4.54 vs 3.26 ng/mL; P = 0.0672) and leptin (19,542 vs 14,210 pg/mL; P = 0.1817) were observed. Decreased concentration of adiponectin was found in patients with SSc (5150 vs 8847 pg/mL; P = 0.0001). Fractalkine and galectin-3 levels were significantly higher in diffuse cutaneous SSc than limited cutaneous SSc subset (3.93 ng/mL vs 2.58 ng/mL, P = 0.0018; 6.86 ng/mL vs 3.78 ng/mL, P = 0.0008, respectively) and correlated positively with modified Rodnan Skin Score in total SSc patients (r = 0.376, P = 0.0009; r = 0.236, P = 0.018, respectively). In conclusion, an increased serum level of resistin associated with increased endothelin-1 and fractalkine level and decreased adiponectin level may indicate a significant role of the adipose tissue in the development and progression of vascular abnormalities in patients with systemic sclerosis. Fractalkine and galectin-3 may participate in promoting and exacerbating the fibrotic process in SSc.

Recent studies point out at the role of apoptosis disturbances in the development of systemic sclerosis (SSc).The aim of our study was to examine caspase 1 and sFas serum levels in scleroderma patients and correlate the obtained results with skin involvement and internal organ changes.We studied 29 patients (14 with limited and 15 with diffuse SSc). The extension of skin involvement was measured using Total Skin Score (TSS). Internal organ involvement was assessed by specialist procedures. Serum caspase 1 and sFas levels were measured by enzyme-linked immunosorbent assay.We found correlation between sFas serum level and duration of Raynaud's phenomenon and TSS; caspase 1 serum level correlated only with TSS. Correlations between caspase 1 and lung dysfunction and sFas levels with joint and bone involvement in SSc patients were also observed.The obtained results revealed that disturbances of apoptosis might play a role in SSc pathogenesis. Caspase 1 and sFas serum levels correlate with the skin involvement severity, lung dysfunction, joint and bone changes.

Abstract Funding Acknowledgements Type of funding sources: None. Background In systemic sclerosis (SSc) myocardial fibrosis contributes to the impairment of the myocardial function resulting in manifest diastolic and subclinical systolic dysfunction of the left ventricle (LV) and impaired left atrial (LA) function. The pathophysiology of this connective tissue disease is still not fully elucidated. Recently, however, elevated serum levels of galectin-3 and soluble suppression of tumorigenicity 2 (sST2) have been reported in SSc patients suggesting that these fibrotic markers may participate in the fibrotic process in this disease. Thus we aimed to investigate the potential associations between galectin-3 and sST2 levels and the echocardiographic markers of the LV and LA function in SSc patients. Methods Forty patients (57.3 ± 13.7 years, 36 female) were enrolled into the study. In addition to the conventional echocardiography, tissue Doppler and speckle-tracking-derived strain techniques were used to estimate the LV systolic and diastolic function as well as the LA size and function. To assess the correlations between galectin-3 and sST2 levels and the echocardiographic variables, partial correlation method was used with age as correcting factor. Results In age adjusted analysis galectin-3 level showed significant correlation with LV global longitudinal strain (r = 0.460, p = 0.005); grade of LV diastolic dysfunction (r = 0.394, p = 0.013); septal e’ (r=-0.369, p = 0.021); septal E/e’ (r = 0.380, p = 0.017) and with the grade of mitral regurgitation (r = 0.323, p = 0.048) (Figure 1). No significant correlation was found between sST2 levels and the echocardiographic variables. Conclusions Galectin-3 levels, but not sST2 levels show significant correlation with the parameters of the LV diastolic function and with LV global longitudinal strain, a parameter reflecting the subclinical impairment of the LV systolic function. Galectin-3 may be a useful biomarker for identifying SSc patients with high risk for cardiac involvement. Abstract Figure 1

Adipose tissue-derived hormones known as adipokines, like leptin, have multiple bioactions. Notwithstanding the key roles of leptin in regulating energy homeostasis and metabolism, its cardiovascular functions are complex and not fully understood. This study aimed to investigate the association between serum concentrations of leptin and lipid profiles in patients with valve calcification. Seventy-two patients with valve calcification and 72 healthy individuals participated in this case-control study. The serum levels of biochemical markers and leptin were measured by the standard enzymatic methods and enzyme-linked immunosorbent assay (ELISA) technique, respectively. Significantly increased serum concentrations of FBS (P=0.001), urea (P<0.0001), creatinine (P=0.018), P (P<0.0001), LDL-C (P=0.011) and lower Ca (P=0.006), and HDL-C (P<0.0001) levels were observed in patients compared to controls. There was no significant difference in the serum level of TG and TC of patients than controls. Systolic and diastolic blood pressures were significantly increased in patients relative to controls (P<0.0001). However, a significantly diminished serum level of leptin was observed in patients than controls (P<0.0001). The correlation analysis demonstrated that the serum leptin concentration is negatively correlated with creatinine, but it is positively correlated with systolic blood pressure (P=0.0302, P=0.0362, respectively). There was no statistically significant association between serum levels of leptin and lipid profiles. Our findings indicated dyslipidemia and reduced serum leptin concentrations in patients with valve calcification, suggesting the role of lipid abnormalities and reduced leptin levels in the development and pathogenesis of valve calcification diseases.

BackgroundGalectin-3-binding protein (GAL-3BP) is a ubiquitous and multifunctional secreted glycoprotein, which functions in innate immunity and has been highlighted as a potential mediator of adipose inflammation in obesity. In this study, we aimed to identify whether GAL-3BP is a novel biological marker for metabolic syndrome (MetS).MethodsThe biochemical and anthropometric variables of the 570 participants in this study were evaluated using standard procedures. Their serum GAL-3BP levels were measured using enzyme-linked immunosorbent assay (ELISA), while the association between the glycoprotein and MetS was analyzed using multiple logistic regression analyses. Moreover, an experimental MetS model was established. The expression of GAL-3BP in serum and adipose tissue was measured using ELISA and western blotting. Lipid accumulation was determined with the use of immunohistochemistry and immunofluorescent staining.ResultsThe serum GAL-3BP level was found to be positively associated with MetS. The logistic regression analyses demonstrated that participants expressing the upper levels of GAL-3BP were more likely to develop MetS than those expressing less of the glycoprotein (OR = 2.39, 95%CI: 1.49, 3.83). The association between the serum GAL-3BP level and MetS was found preferentially in postmenopausal women (OR = 2.30, 95%CI: 1.31, 4.05). In addition, GAL-3BP was increased in the serum and visceral adipose tissue (VAT) of high fat diet (HFD) mice. Moreover, GAL-3BP was highly expressed in VAT macrophages.ConclusionsThis study confirmed serum GAL-3BP to be positively associated with MetS, highlighting it as a useful biological marker of MetS in Chinese participants.

Цель. Изучить закономерности изменения экспрессии интерлейкина-10 и интерлейкина-24, обладающих иммуномодулирующим эффектом, при развитии B-клеточного хронического лимфолейкоза. С учетом этого выявить информативные прогностические критерии развития гемобластоза и/или нового подхода к терапии заболевания. Методы. У 120 больных с разными стадиями В-клеточного хронического лимфолейкоза методом твердофазного иммуноферментного анализа исследована динамика уровней интерлейкина-10 и интерлейкина-24 в сыворотке крови. Результаты. Обнаружено закономерное повышение содержания интерлейкина-10 и интерлейкина-24 в сыворотке крови пациентов уже на начальной стадии B-клеточного хронического лимфолейкоза и сохранение их достоверно высоких уровней на последующих стадиях заболевания. Заключение. Обнаруженный нами факт повышения содержания интерлейкина-10 в сыворотке крови пациентов с В-клеточным хроническим лимфолейкозом является фактором риска снижения противоопухолевой защиты организма вследствие подавления им механизмов клеточного иммунитета и способности ингибировать апоптоз малигнизированных клеток. Напротив, повышение экспрессии интерлейкина-24, обладающего проапоптотической активностью и стимулирующего дифференцировку клеток, может способствовать повышению эффективности механизмов противоопухолевой резистентности организма. Устранение дисбаланса продукции и/или содержания указанных цитокинов в сыворотке крови может создать условия повышения эффективности терапии пациентов с В-клеточным хроническим лимфолейкозом. Aim. To study serum levels of immunosuppressive cytokines (interleukin (IL)-10 and IL-24) in patients with B-cell chronic lymphocytic leukemia for assessment of the disease progression and elaboration of a new treatment strategy. Methods. 120 patients with B-cell chronic lymphocytic leukemia were enrolled in the study and divided into four groups according to the disease stage (Rai stage I-IV). Control group included 30 healthy volunteers. Concentrations of IL-10 and IL-24 were measured in serum using the enzyme-linked immunosorbent assay (ELISA). Results. Serum levels of IL-10 and IL-24 levels were significantly increased in all patient groups compared to the control. No difference in the cytokines levels between the patient groups was observed. Conclusion. In patients with B-cell chronic lymphocytic leukemia, the increased serum level of IL-10 might impair the antitumor defence by inhibiting the cell immune response and preventing apoptosis of malignant lymphocytes. On the other hand, the increased serum level of IL-24 might oppose these effects by promoting cellular differentiation and inducing apoptosis in malignant cells. Therefore, correction of IL-10/IL-24 imbalance may be a beneficial therapeutic strategy for patients with B-cell chronic lymphocytic leukemia.

Background: Erythroferrone (ERFE) is a glycoprotein hormone synthesis and release by erythroblasts. Recently identified as an erythropoietic regulator and activated in response to stimulating erythropoietin (Epo). In chronic kidney diseases (CKD), anemia is a hallmark disorder due to a decrease in hyposensitive erythropoietic to the Epo; these patients recommended to use of Erythropoiesis-stimulating agents (ESAs). The aim: This study aimed to assess serum ERFE level in patients with CKD and investigate the continuing effects of long-term anemic ESA use associated with markers of erythropoiesis and iron metabolism. Methods: Sixty-five CKD patients divided in two groups, included 30 hemodialyses (HD) and 35 without hemodialysis (non-HD) CKD patients, were compared to 25 healthy voluntaries matched by gender and age enrolled in the current study. Serum ERFE level was measured by an enzyme-linked immunosorbent assay (ELISA). Results: Serum ERFE level was significantly elevated in HD patients median (IQR) about 17.25 (13.4) ng/mL, odds ratio (OR = 10.161), (AUC 0.996) greater than CKD 4(6.1) ng/ml, (OR = 6.295), (AUC = 0.984) p 0.001; also, these are positively correlated with the use of ESA in HD, and CKD (r = 1.00 and r = 0.95) respectively as compared to healthy group 2(2.1) ng/ml. Serum ERFE levels were significantly negative (p 0.05) in both CKD and HD patients related to GFR (r = -0.396, and r = -0.68), transferrin saturation (TS%) (r = -0.842, and r = -0.877), serum levels of Ferritin (r = -0.865 and r = -0.866), and Iron (r = -0.860, and r = -0.851), RBC (r = -0.841, and r = -0.843), hemoglobin (Hb) (r = -0.758, and r = -0.796). Conclusion: The present study demonstrated that elevated serum ERFE levels associated with erythropoietic activity and anemia are higher in CKD with HD and non -HD patients treated with ESA than in non-ESA patients. This study suggested using ERFE as a successful tool for erythropoietic activity inspection in CKD, especially those taking ESAs to treat anemia.

The Impact

Background. Psoriasis is a chronic systemic inflammatory disease associated with a wide range of comorbidities, including metabolic syndrome (MetS). Serum calprotectin, ANGPTL8, and oxidative damage to nucleic acids might be associated with both diseases. The presented study describes the influence of psoriasis and MetS on the serum levels of markers of systemic inflammation (calprotectin and ANGPTL8) and markers of oxidative damage to nucleic acids. The applicability of serum levels of calprotectin and ANGPTL8 for monitoring of the activity of psoriasis (diagnostic markers) is also evaluated. Methods. Clinical examination (PASI score, MetS), enzyme-linked immunosorbent assay (ELISA), and Enzyme Immunoassay (EIA). Serum calprotectin, ANGPTL8, 8-hydroxy-2′-deoxyguanosine, 8-hydroxyguanosine, and 8-hydroxyguanine. Results and Conclusions. The psoriasis significantly increased the serum level of calprotectin and the serum level of oxidative damage to nucleic acids, however not the serum level of ANGPTL8. The presence of MetS did not significantly affect the serum levels of calprotectin, ANGPTL8, and oxidative damage to nucleic acids in either psoriasis patients or controls. It seems that the serum level of calprotectin (but not the serum level of ANGPTL8) could be used as a biomarker for monitoring the activity of psoriasis.

Resistin and adiponectin, recently discovered adipokines, are secreted from adipose tissue, with postulated opposing functions in insulin resistance and inflammation. More recently, an abundance of resistin was detected in macrophages, which suggests its important role in inflammation. The aim of this study was to clarify circulating serum adipokine levels in women with periodontitis. Thirty-four women with moderate to severe periodontitis and 42 control individuals with healthy gingiva (50- to 59-year-old women) were selected. The serum level of adipokines was analyzed between groups, along with the obesity index, smoking status, and age. Having periodontitis was significantly associated with an increased level of resistin, both in bivariate (OR, 3.0; 95% CI, 1.2–7.6) and multivariate (adjusted OR, 3.1; 95% CI, 1.1–8.6) analyses. The association of periodontitis with a decreased level of adiponectin did not reach statistical significance. It was concluded that an increased serum resistin level in middle-aged Japanese women with periodontitis may affect systemic health.
