Background and Objectives: Non-alcoholic fatty liver disease is a worldwide significant public health problem, particularly in patients with type 2 diabetes mellitus. Identifying possible risk factors for the disease is mandatory for a better understandingand management of this condition. Patatin-like phospholipase domain-containing protein 3 (PNPLA3) has been linked to the development and evolution of fatty liver but not to insulin resistance. The aim of this study isto evaluate the relationships between PNPLA3 and fatty liver, metabolic syndrome and subclinical atherosclerosis. Materials and Methods: The study group consisted of patients with type 2 diabetes mellitus without insulin treatment. The degree of liver fat loading was assessed by ultrasonography, and subclinical atherosclerosis was assessed using carotid intima-media thickness (CIMT). PNPLA3 rs738409 genotype determination was performed by high-resolution melting analysis that allowed three standard genotypes: CC, CG, and GG. Results: Among the 92 patients, more than 90% showed various degrees of hepatic steatosis, almost 62% presented values over the normal limit for the CIMT. The majority of the included subjects met the criteria for metabolic syndrome. Genotyping of PNPLA3 in 68 patients showed that the difference between subjects without steatosis and subjects with hepatic steatosis was due to the higher frequency of genotype GG. The CC genotype was the most common in the group we studied and was significantly more frequent in the group of subjects with severe steatosis; the GG genotype was significantly more frequent in subjects with moderate steatosis; the frequency of the CG genotype was not significantly different among the groups.When we divided the group of subjects into two groups: those with no or mild steatosis and those with moderate or severe steatosis it was shown that the frequency of the GG genotype was significantly higher in the group of subjects with moderate or severe steatosis. PNPLA3 genotypes were not associated with metabolic syndrome, subclinical atherosclerosis, or insulin resistance. Conclusions: Our results suggest that PNPLA3 does not independently influence cardiovascular risk in patients with type 2 diabetes mellitus. The hypothesis that PNPLA3 may have a cardioprotective effect requires future confirmation.

ABSTRACT Objective: to identify the prevalence of Metabolic Syndrome and its components in a population of patients with type 2 Diabetes Mellitus. Method: a cross-sectional study was conducted with 201 diabetic patients. A descriptive analysis and Chi-square and Fisher's exact tests ( p <0.05) were performed. Results: the majority of participants were females and overweight, with a mean age of 63.1 years and a low level of education, and categorized as physically inactive. Of all individuals investigated, 50.7% were diagnosed with Metabolic Syndrome and 92% had at least one of the syndrome components with values beyond those recommended. Conclusion: it is essential to take preventive actions and develop studies that help to identify the factors associated with this syndrome.

Background: Musclin is a newly identified skeletal muscle–derived secretory factor, which has been recently characterized as a stimulator that induces insulin resistance in mice. However, the pathophysiological role of musclin in humans remains poorly understood. The aim of this study was to explore the potential correlations between musclin plasma levels and various metabolic parameters in patients with type 2 diabetes mellitus. Materials and methods: In this hospital-based study, plasma samples were collected from the enrolled individuals, including 38 newly diagnosed, treatment-naive type 2 diabetes mellitus patients and 41 age- and gender-matched control subjects. Plasma musclin levels were examined by radioimmunoassay. Results: Compared with the control group, musclin plasma levels were significantly higher in untreated type 2 diabetes mellitus patients. Musclin levels in the plasma of newly diagnosed type 2 diabetes mellitus patients were positively correlated with fasting plasma glucose, haemoglobin A1c, serum insulin, triglycerides and homeostasis model assessment of insulin resistance. Furthermore, multivariate logistic regression analysis showed that the level of musclin was associated with the presence of type 2 diabetes mellitus. Receiver operating characteristic curve analysis yielded an area under the curve for musclin of 0.718 in type 2 diabetes mellitus. Conclusion: The circulating concentration of musclin was significantly increased in type 2 diabetes mellitus patients. Our results suggest that musclin has a strong relationship with insulin resistance in type 2 diabetes mellitus.

Aims: To assess hepatic steatosis and fibrosis in patients of type 2 diabetes mellitus (T2DM), their possible risk factors and their association with metabolic syndrome and micro or macro-albuminuria. Study Design: Cross sectional study. Place and Duration of Study: Outpatient Clinic of Diabetes, Metabolism and Endocrinology Unit in internal medicine department, Tanta University, Egypt in a period between September 2019 to March 2020. Methodology: We included 200 patients had a diagnosis of T2DM according to American Diabetes Association criteria. Then patients were assessed for presence of hepatic steatosis and fibrosis using fibroscan and we used liver stiffness measurements (LSMs, as a measure of fibrosis) and controlled attenuation parameter (CAP, as a measure of steatosis) and routine laboratory data were done to rule out possible risk factors. Results: 98.5% of participants had hepatic steatosis and 53.5% of participants had hepatic fibrosis. Those patients had longer duration of DM, higher BMI, bad control of T2DM, higher lipid profile values, association with metabolic syndrome, micro and macro-albuminuria and non-significantly elevated liver enzymes. Conclusion: Hepatic steatosis and fibrosis are highly prevalent in patients with T2DM, incidence of hepatic steatosis and fibrosis is positively correlated with longer duration of DM, higher BMI, bad control of DM, dyslipidemia, presence of metabolic syndrome, diabetic nephropathy, weakly correlated with liver enzymes. TE is an accurate and non-invasive tool to be used in screening for hepatic steatosis and fibrosis ,so we recommend screening for hepatic steatosis and fibrosis using fibroscan to help in early management and prevent its progression into liver cirrhosis.

AbstractIn 2016, the World Health Organization estimated that more than 1.9 billion adults were overweight or obese. This impressive number shows that weight excess is pandemic. Overweight and obesity are closely associated with a high risk of comorbidities, such as insulin resistance and its most important outcomes, including metabolic syndrome, type 2 diabetes mellitus, and cardiovascular disease. Adiponectin has emerged as a salutary adipocytokine, with insulin-sensitizing, anti-inflammatory, and cardiovascular protective properties. However, under metabolically unfavorable conditions, visceral adipose tissue-derived inflammatory cytokines might reduce the transcription of the adiponectin gene and consequently its circulating levels. Low circulating levels of adiponectin are negatively associated with various conditions, such as insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. In contrast, several recent clinical trials and meta-analyses have reported high circulating adiponectin levels positively associated with cardiovascular mortality and all-cause mortality. These results are biologically intriguing and counterintuitive, and came to be termed “the adiponectin paradox”. Adiponectin paradox is frequently associated with adiponectin resistance, a concept related with the downregulation of adiponectin receptors in insulin-resistant states. We review this contradiction between the apparent role of adiponectin as a health promoter and the recent evidence from Mendelian randomization studies indicating that circulating adiponectin levels are an unexpected predictor of increased morbidity and mortality rates in several clinical conditions. We also critically review the therapeutic perspective of synthetic peptide adiponectin receptors agonist that has been postulated as a promising alternative for the treatment of metabolic syndrome and type 2 diabetes mellitus.
