Concentrations of Connective Tissue Growth Factor in Patients with Nonalcoholic Fatty Liver Disease: Association with Liver Fibrosis

Aim: In this study, we aimed to investigate the relationship between the histological fibrosis stage of nonalcoholic fatty liver disease (NAFLD) and serum connective tissue growth factor (CTGF) to determine the usefulness of this relationship in clinical practice. Methods: Serum samples were collected from 51 patients with biopsy-proven NAFLD and 28 healthy controls, and serum levels of CTGF were assayed by ELISA. Results: Levels of CTGF were significantly higher in patients with NAFLD compared with controls (P = 0.001). The serum CTGF levels were significantly increased, that correlated with histological fibrosis stage, in patients with NAFLD [in patients with no fibrosis (stage 0) 308.2 ± 142.9, with mild fibrosis (stage 1–2) 519.9±375.2 and with advanced fibrosis (stage 3–4) 1353.2 ± 610 ng/l, P < 0.001]. Also serum level of CTGF was found as an independent predictor of histological fibrosis stage in patients with NAFLD (β = 0.662, t = 5.6, P < 0.001). The area under the ROC curve was estimated 0.931 to separate patients with severe fibrosis from patients with other fibrotic stages. Conclusion: Serum levels of CTGF may be a clinical utility for distinguishing NAFLD patients with and without advanced fibrosis

Extracellular matrix protein 1 gene rs3737240 single nucleotide polymorphism is associated with ulcerative colitis in Turkish patients

Background/Aims: Ulcerative colitis (UC) and Crohn's disease are chronic inflammatory diseases. Genetic, immunologic, and microbial factors play an important role in their pathogenesis. Extracellular matrix protein 1 (ECM1), a gene related to mucosal barrier function, has been shown to be associated with UC. This study aims to determine the relationship between ECM1 gene rs3737240 single nucleotide polymorphism (SNP) and UC in a group of Turkish patients

A Potential Treatment of Non-Alcoholic Fatty Liver Disease with SIRT1 Activators

Sirtuins (SIRTs) are members of the silent information regulator-2 family and act as nicotinamide adenine dinucleotide (NAD+)-dependent histone/protein deacetylases. The de-acetylation of proteins and histones results in an up- or down-regulation of gene transcription and protein function. In recent years, the regulatory action of the deacetylation activity of SIRT1 has been shown to have a positive impact on the pathophysiological mechanisms of nonalcoholic fatty liver disease (NAFLD). Among the effects of SIRT1 are: its healing activity on insulin sensitivity, thereby ameliorating glycemic regulation; its mimetic activity on calorie restriction; its antihyperlipidemic activity on lipid homeostasis via the liver, adipose tissues and skeletal muscles; its anti-inflammatory activities; its protective effects against cardiovascular events and endothelial dysfunction; its positive influence on autophagy, apoptosis and cancer; and finally, its anti-aging activity. The current approach for the treatment of NAFLD involves the treatment of etiological factors and recommendation of life-style changes including more physical activity and a low-calorie diet. However, there is no specific medical treatments for NAFLD. The therapeutic potential of SIRT1 activity in the treatment of NAFLD discovered in humans has been presented in this article. In this review, the potential effects of SIRT1 activation on NAFLD-related pathophysiological mechanisms and on the treatment of NAFLD are discussed

Evaluation of depression, anxiety, alexithymia, attachment, social support and somatization in functional dyspepsia

AIM: The psychiatric and psychosocial aetiology of Functional dyspepsia is not well known. In the present study, our aim is to determine the relative contributions of psychiatric predictors – i.e. depression, anxiety, somatization, alexithymia – in relation with socio-psychological factors, specifically their personal characteristics (i.e. emotional attachment) and perceived social support, in distinguishing FD from organic dyspepsia and healthy samples. MATERIAL AND METHODS: An estimated 30 functional dyspepsia, 29 organic dyspepsia patients who were admitted to our gastroenterology outpatient clinic and 27 healthy controls were enrolled to our study. Beck Depression Inventory, Toronto Alexithymia Scale, Adult Attachment Scale, State-Trait Anxiety Inventory, Multidimensional Scale of Perceived Social Support and somatization sub-scale of Symptom Checklist-90 were provided to all patients and healthy controls. All participants were examined by a gastroenterologist and a psychiatrist. RESULTS: Healthy controls were younger than organic dyspepsia group and women/men rate was lower in organic dyspepsia than other two groups. Depression score was higher in functional dyspepsia group than in healthy controls and functional dyspepsia group’s attachment syle was more secure than that of the healthy control group. Somatization rate was seen higher in functional dyspepsia group with psychiatric examination. There was no significant difference seen in anxiety, alexithymia and social support between the three groups. DISCUSSION: Anxious-avoidant attachment profile as well as the higher propensity to have depressive and anxiety symptoms might be critical psychiatric and psychosocial factors underlying FD’s aetiology. A multidisciplinary approach is needed in the follow up of functional dyspepsia patients. Psychological evaluation and treatment would increase the life quality of dyspepsia patients

Plasma Fibrinogen-Like Protein 2 Levels in Patients with Non-Alcoholic Fatty Liver Disease

Background/Aims: Fibrinogen-like protein 2 (fgl2), has recently been identified as a new member of the fibrinogen-like family of proteins. In this study we assayed plasma levels of fgl2 in patients with biopsy proven non-alcoholic fatty liver disease (NAFLD) and examined their association with clinical, biochemical and histological phenotypes. Methodology: Levels of plasma fgl2 were measured by enzyme linked immunosorbent assay and compared between the study groups. Moreover, concentrations of fgl2 were assessed in relation to the general characteristics of the study participants and the results of the liver biopsy. Results: Levels of fgl2 were significantly higher in patients with definite non-alcoholic steatohepatitis (NASH) (788 +/- 190pg/mL, p<0.001) and borderline NASH (710 +/- 140pg/mL, p<0.001) compared with controls (515 +/- 174pg/mL). No significant differences were found in patients with simple steatosis (649 +/- 162pg/mL) as compared with controls. There were no associations between the plasma fgl2 levels with the fibrosis stage and steatosis grade. Conclusions: Although subject to future confirmation, our data suggest that fgl2 levels are elevated in the more severe forms of NAFLD
