Lege Artis Medicinae - 2011;21(12)

[Linagliptin is a xantin-based, highly selective, potent inhibitor of dipeptidyl peptidase- IV (DPP-4). By inhibiting DPP-4, linagliptin reduces the degradation of endogenous incretin hormones, and thus increases insulin secretion and decreases glucagon secretion in the pancreatic islets in a glucose-dependent manner. The author summarises the most important clinical trials with linagliptin, which highlight those features of linagliptin that distinguish it from other DPP-4 inhibitors.]

[Occurrence of cardiometabolic risk factors among shift workers]

JERMENDY György, NÁDASI Judit, HEGYI Ilona, VASAS István, HIDVÉGI Tibor

[INTRODUCTION - Shift workers have an impaired circadian rhythm, which might have an adverse effect on their health. In order to assess cardiometabolic risk in shift workers, a cross-sectional study was performed among active workers (aged 25-66 years, with a minimal shift working experience of 5 years). METHODS - In total 481 workers (121 men, 360 women) registered by the occupational health service were enrolled in our study. Most participants worked in the light industry (58.2%) or in public service (23.9%). Following questionnaire-based data recording, anthropometric measurements and physical examination were performed and fasting venous blood sample was taken for measuring laboratory parameters. Data from shift workers (n=234, 54 men and 180 women, age: 43.9±8.1 years) were compared with those of day workers (n=247, 67 men and 180 women, age: 42.8±8.5 years). RESULTS - Compared with day workers, shift workers had bigger weight (76.6±16.1 vs 73.9±17.6 kg; p<0.05), higher BMI index (27.5±5.3 vs 26.0±4.9 kg/m2; p<0.01) and systolic blood pressure (123±19 vs 119±16 mmHg, p<0.01), and higher prevalence rate of diabetes (4.3 vs 1.2 %; p<0.05) and cardiovascular diseases (3.8 vs 0.8 %; p<0.05). In addition, the proportion of participants who performed regular physical activity was lower (20.6 vs 38.7 %; p<0.001) and that of current smokers were higher (35.0 % vs 19.5 %; p<0.001) in shift workers than in day workers. In laboratory findings, only one difference has been found: HDL-cholesterol level was lower among women (shift workers versus workers: 1.56±0.32 vs 1.68±0.36 mmol/l; p<0.01). CONCLUSION - Long-term shift work (day-night) results in a less healthy lifestyle and worse cardiometabolic risk factors compared with day work. Thus, our study highlights the importance of measures for preventing cardiovascular diseases in shift workers.]

[Patients with type-1 and type-2 diabetes mellitus in the program of peritoneal dialysis]

JUHÁSZNÉ LESKÓ Mónika, GYÖRFI Gáborné, LADÁNYI Erzsébet

[Aim of the research: To evaluate the efficacy of the treatment and incidence of complications in diabetes type 1 and 2 patients treated with peritoneal dialysis. Research and sampling methods: During a retrospective study with 85 diabetic PD patients (19 type 1 patients and 66 type 2 patients) was compared data of 22 years with regard to the following parameters: Glucose metabolism, body weight, changes in residual urine clearance values, distribution of quantity and glucose content of the solutions used, incidence of infections, and average duration in PD programme before transferring to haemodialysis. Results: All patients, irrespective of their type of diabetes: spend the same time in PD on average, gained body weight during PD. Diabetes type 1 patients: had a lower residual urine clearance, had HbA1c values decreasing during PD, reported peritonitis less frequently, had a higher incidence of catheter-related infections. Diabetes type 2 patients: had a better glucose metabolism, had a higher body weight from the beginning of therapy, required PD solution with higher glucose concentration. Conclusions: Diabetes patients, irrespective of the type of diabetes, can successfully be treated with PD, but require more attention because of their underlying disease and associated complications. ]

[Relationship between adipokinome and lipid parameters in Hungarian obese patients]

LŐRINCZ Hajnalka

[Since the prevalence of obesity has been dramatically increasing worldwide, a better understanding of obesity-related comorbidities leading to carbohydrate and lipid metabolism disorders has become essential. As an active endocrine organ, white adipose tissue secretes adipokines with diverse biological functions. We have found strong correlations between serum chemerin level and atherogenic lipoprotein sub-fractions in obese non-diabetic patients. To better characterize obese patients with and without manifest insulin resistance, we plan to determine serum levels of novel adipokines (omentin-1, vaspin, visfatin, lipocalin-2 and plasminogen activator inhibitor-1) and various oxidative stress markers including paraoxonase-1 activity, tumor necrosis factor-alfa and interleukin-6 levels, as well as low- and high-density lipoprotein subfractions in them and compare their data with lean individuals. We plan to determine correlations between the levels of novel adipokines and oxidative stress markers and lipoprotein subfractions. Furthermore, based upon our previous observations, we plan to study the potential alterations in the adipokine profile and the ratios of lipoprotein subfractions during a 5-year follow-up in obese patients. Our expected results may help to characterize the involvement of the adipokine profile in the regulation of lipoprotein metabolism. Early screening and treatment of lipid abnormalities may help to reduce the risk of cardiovascular events in obesity. ]

[THE SENSOR-AUGMENTED INSULIN PUMP AND ITS USE IN CLINICAL PRACTICE]

KÁNTOR Irén

[Diabetes is one of the most common chronic diseases. Technological advances provide increasingly refined tools for clinicians to manage type 1 and type 2 diabetes. Continuous subcutaneous insulin infusion (CSII), also known as insulin pump, allows for a sophisticated delivery of basal as well as bolus insulin. Continuous glucose monitoring helps patients and clinicians understand and manage changes in blood glucose trends and minute-to-minute blood glucose variablitiy. The sensor-augmented insulin pump was created by the merging of these devices, which has been a revolutionary step towards self-regulatory, closed-loop insulin delivery or the creation of an artificial pancreas.]

[BRAIN INSULIN SIGNALLING IN THE REGULATION OF ENERGY BALANCE AND PERIPHERAL METABOLISM]

MICHAELA Diamant

[The unparalleled global rates of obesity and type 2 diabetes, together with the associated cardiovascular morbidity and mortality, are referred to as the "diabesity pandemic". Changes in lifestyle occurring worldwide, including the increased consumption of high-caloric foods and reduced exercise, are regarded as the main causal factors. Central obesity and insulin resistance have emerged as important linking components. Understanding the aetiology of the cluster of pathologies that leads to the increased risk is instrumental in the development of preventive and therapeutic strategies. Historically, skeletal muscle, adipose tissue and liver were regarded as key insulin target organs involved in insulinmediated regulation of peripheral carbohydrate, lipid and protein metabolism. The consequences of impaired insulin action in these organs were deemed to explain the functional and structural abnormalities associated with insulin resistance. The discovery of insulin receptors in the central nervous system, the detection of insulin in the cerebrospinal fluid after peripheral insulin administration and the well-documented effects of intracerebroventricularly injected insulin on energy homeostasis, have identified the brain as an important target for insulin action. In addition to its critical role as a peripheral signal integrating the complex network of hypothalamic neuropeptides and neurotransmitters that influence parameters of energy balance, central nervous insulin signalling is also implicated in the regulation of peripheral glucose metabolism. This review summarizes the evidence of insulin action in the brain as part of the multifaceted circuit involved in the central regulation of energy and glucose homeostasis, and discuss the role of impaired central nervous insulin signalling as a pathogenic factor in the obesity and type 2 diabetes epidemic.]

[Deeper analysis of nebivolol effects]

KÉKES Ede

[Author presents the formation of nitric oxide as a largest vasodilator of human endothelium as well as the endothelial dysfunction a result of formation at adrenergic stimulus. He demonstrates in detail the benefits of selective β-1 blocker and β-3 adrenergic agonist nebivolol in the vascular system. This drug has also receptor independent effects. Complex effects of nebivolol causes vasodilation, inhibits oxidative stress and it is capable to neutralize the effects of free oxygen radicals and as a result the endothelial function will be better. Its clinical effects and the less wellknown beneficial properties are listed. The use of drug is discussed especially in hypertensives with smoking, COPD or PAD. The β-3 agonist effect provides positive reactions not only in the adipocytes and the myocardial tissue. but in the skeletal muscle as well: Increase in energy expenditure - as a compensatory mechanism - is increased in obesity and the glucose uptake + storage on skeletal muscle cells are increased in hyperglycemia. The insulin sensitivity will be better, leptin level is decreased, adiponectin level is increased by nebivolol. It is assumed this drug has antidiabetic and anti-obesity effects.]
