This review deals with the role of adipose tissue inflammation (ATI) in the development of type 2 diabetes mellitus (DM2). ATI is regarded as a link between obesity and DM2. The review illustrates the involvement of main adipokines in pathogenesis of DM2 and provides a detailed description of such factors as impaired adiponectin and stimulation of cytokine production responsible for metabolic disorders, activation of lipolysis, in adipocytes, increased fatty acid and triglyceride levels, suppression of insulin activity at the receptor and intracellular levels. Adipokines, in the first place cytokines, act on the insulin signal pathway and affect the intracellular inflammatory kinase cascade. At the intercellular level, ATI stimulates JNK and IKK-beta/kB responsible for the development of insulin resistance via such mechanisms as activation of cytokine secretion in the adipose tissue, oxidative stress, and induction of endoplasmic reticulum enzymes. The key role of JNK and IKK-beta/kB in the inhibition of the insulin signal pathway is mediated through inactivation of insulin receptor substrate 1. Also, it is shown that ATI modulates B-cell function and promotes progressive reduction of insulin secretion.

The paper reviews publications concerned the role of nonesterifi ed fatty acids (NEFA) in pathogenesis of cardiovascular diseases. NEFAs are four and more carbons chain length carbonic acids and they are presented in free form (nonesterifi ed) in human body. Plasma NEFAs are produced by the adipose tissue triglyceride lipolysis, another source are lipoproteins such as chylomicrons, very low density lipoproteins and intermediate density lipoproteins. Elevated NEFA concentrations in plasma are the risk factor of cardiovascular diseases and type 2 diabetes mellitus and the independent risk factor of hypertension and sudden death. NEFA plasma concentration is elevated in atherosclerosis, acute myocardial infarction, diabetes mellitus, obesity, hypertension, and often in metabolic syndrome. A probable cause of NEFAs accumulation in plasma may be overeating and low physical activity, which result in increase of adipose tissue mass, lipolysis intensifi cation and elevation of NEFAs concentration in plasma. The role of elevated plasma NEFA concentration in a number of conditions (abdominal obesity, atherogenic dyslipidemia, insulin resistance, type 2 diabetes mellitus, endothelial dysfunction, vascular infl ammation, atherosclerosis, hypertension, ischemic heart disease, rhythm disturbances, sudden death) and possible ways of their correction are discussed.

Aim of this paper is to consider the role of hormones of the adipose tissue in mechanisms of obesity, metabolic syndrome, type 2 diabetes mellitus upon chronic pancreatitis. Materials and methods. The literature review indicates the value of visceral fat in the development of insulin resistance, dyslipidemia, including atherogenic one, taking into account the possible infiltration of pancreatic tissue by adipocytes. Participation of some adipocytokines of adipose tissue in the development of obesity upon chronic pancreatitis is highlighted. It is shown that in some cases the hormones of visceral adipose tissue, penetrating through the portal vein to the liver and then to the pancreas, aggravated the course of systemic chronic inflammation of the inherent chronic pancreatitis, promote steatosis and development of fatty pancreatic disease. Conclusion. Literary sources indicate the leading role of visceral adipose tissue and its hormones in the formation of obesity in chronic pancreatitis. Due to the infiltration of the pancreatic tissue by adipocytes, lipoidosis and steatosis develop. With the progression of the process type 2 diabetes mellitus, fatty liver or pancreatic disease, or cancer of these orhans. Consequently, there is a need for serious differentiated preventive and curative measures aimed at promoting a healthy lifestyle to improve the quality of life of patients suffering from chronic pancreatitis.

The article presents data on the prevalence of diabetes and prediabetes; the high compatibility of diabetes mellitus and cardiovascular pathology; high mortality among patients with diabetes mellitus and coronary heart disease, in the presence of both acute and chronic cardiovascular complications; on the important role of glucose- and lipotoxicity in the progression of carbohydrate metabolism from prediabetes to type 2 diabetes mellitus, the role of hyperglycemia in the deve-lopment of insulin resistance, atherosclerosis, hypertension, liver, kidney, endothelial dysfunction, the role of hyper- and hypoglycemia in the development of acute vascular complications – myocardial infarction, stroke, gangrene of the lower extremities; on the protective role of adiponectin – a predictor of type 2 diabetes mellitus, on the importance of glycemic control for the timely detection of early disorders of carbohydrate metabolism – impaired glucose tolerance and impaired fasting glucose; on the role of metformin in the prevention of progression of prediabetes to type 2 diabetes and cardiac pathology; on the gluco- and cardioprotective role of modern sugar-lowering drugs.

For many years, the diagnosis of diabetes has been made through the laboratory- based measurement of fasting or random blood glucose levels or using OGTT. In the case of diabetes, the major outcome of interest is long term micro vascular complications for which a large body of data has been accumulated leading to the endorsement of HbA1C for diagnosis in many countries worldwide, with some variations in cut-offs and testing strategies.Faridpur Med.

Purpose. To evaluate neurodegeneration in patients with type 2 diabetes mellitus (DM2) without diabetic retinopathy and to assess the possible role of systemic vascular complications in retinal changes. Methods. Sixty eyes of 60 patients with DM2 and without any signs of diabetic retinopathy and 60 eyes of 60 healthy controls underwent retinal evaluation using Spectralis optical coherence tomography. Macular ganglion cell layer (GCL) and retinal nerve fiber layer (RNFL) were evaluated. Peripapillary RNFL thickness was assessed using Glaucoma and Axonal Analytics applications. Comparison between patients with the presence/absence of systemic vascular complications and different disease duration was made. Results. Macular GCL was reduced in patients compared to controls (p<0.001). Differences in the macular RNFL thickness were only observed in the outer inferior sector (p=0.033). A reduction in the peripapillary RNFL (average, inferior, and inferotemporal thickness, p<0.05 for all three) was observed in patients using both applications. Patients with chronic systemic vascular complications presented a reduction in the temporal RNFL (p=0.019) compared to patients without complications. The superotemporal RNFL thickness was thinner in patients with longer disease duration. Conclusions. Patients with type 2 DM without diabetic retinopathy and good metabolic control present neurodegeneration affecting neurons in the macular area and axons in different sectors of the optic disc. Systemic vascular complications contributed to further axonal damage in these patients, suggesting a possible role of subclinical ischaemia to retinal neurodegeneration in type 2 DM.
