Introduction: Because of increasing prevalence of T2MD worldwide, it’s very important to recognize risk factors for diabetic complications, as soon as possible. Symptoms of complications appear a few or many years after tissue damage. So, it’s imperative to establish surveillance of diabetics with laboratory and other diagnostic procedures for early recognition of diabetic complications. Follow up of clinical curs of diabetes, by using databases of patients, provide possibility for permanent analysis of important laboratory parameters and any changes could be registered. Although an emerging evidence suggests a strong association of ALT (alanine aminotransferase) and γGT (gamma glutamyl transferase) activity with type 2 diabetes mellitus (T2DM), only a limited number of studies have analyzed the association of AST (aspartate aminotransferase), ALT, γGT, and ALP (alkaline phosphatase) activities in controlled T2DM. Material and Methods: Gender differences are of special interest in trying to follow diabetes progression and development of its complications. Here the activities of ALT, AST, γGT, ALP were analyzed as well as levels of glycosylated hemoglobin (HbA1c) and fasting plasma glucose (FPG) in 40 T2DM patients and 40 age-matched healthy subjects. Blood samples were collected from all participants in regular 3-months intervals up to 6 months period. Standard IFCC enzyme protocols were used to determine enzyme activities. Results and discussion: In first measured interval, significantly higher activities of ALT (p= 0,050) and glucose levels (p=0,045) were shown in male. A significant correlation was shown between ALT and AST activity with FPG and HbA1c levels in first and third measured interval. ALT activity was much higher in the group of patients with poor glycemia control. Average levels of activities of enzymes stay nearly in normal limits, but changes of enzymes activities should be recognized as soon as possible, earlier than tissue changes and diabetic complications become irreversible.

Metformin is the most widely used oral anti‐diabetes agent and has considerable benefits over other therapies, yet 20–30% of people develop gastrointestinal side effects, and 5% are unable to tolerate metformin due to the severity of these side effects. The mechanism for gastrointestinal side effects and their considerable inter‐individual variability is unclear. We have recently shown the association between organic cation transporter 1 (OCT1) variants and severe intolerance to metformin in people with Type 2 diabetes. The aim of this study was to explore the association of OCT1 reduced‐function polymorphisms with common metformin‐induced gastrointestinal side effects in Type 2 diabetes.

To investigate association of two LPIN1 gene variations with main traits of metabolic syndrome (MS) (waist circumference, body mass index, blood pressure, triglycerides, HDL-cholesterol and fasting glucose levels) in population from Bosnia and Herzegovina.

AIM To investigate whether chronic statin treatment after coronary artery bypass grafting (CABG) protects patients from major cardiac events and provides percutaneous coronary intervention (PCI) free survival. METHODS A total of 232 patients with previous CABG and chronic statin therapy were selected retrospectively and were divided into two groups according to a dosage of atorvastatin per day, e. g., 20 mg or 40 mg. Groups were compared for the major cardiac events and freedom from PCI by Kaplan Meier analysis as the primary end point. Patency of grafts including left internal thoracic artery (LITA) and saphenous vein (SVG) and progression of non-grafted native vessel disease were also evaluated as secondary end points. RESULTS Cardiac mortality, periprocedural myocardial infarction (MI), target vessel revascularization and percutaneous coronary intervention free survival were as follows: 2.9% versus 2.1% (p=1.000); 16.1% versus 21.1% (p=0.331); 56.93% versus 52.63% (p>0.005); 58.4% versus 63.2% (log-rank test; p= 0.347) in atorvastatin 20 mg and atorvastatin 40 mg groups, respectively. However, these results were not statistically significant between two groups (p>0.005). Patency of openness of grafts including LITA and SVG and progression of non-grafted native vessel disease were similar between groups (p=0.112, p=0.779, p=0.379 and p=0.663, respectively). CONCLUSION Low-dose long-term statin treatment had similar outcomes on major cardiac events and identical rate of freedom from percutaneous coronary intervention after coronary artery bypass grafting compared with high-dose long-term statin treatment. It is better to start from low dose statin treatment after surgical interventions.
