Background/aim: Acute hyperglycemia is generally a frequently encountered condition in the emergency department (ED), because it is seen as a complication of diabetes mellitus (DM). In this study, we aimed to detect the change in adiponectin levels during acute hyperglycemic states and after normalization of blood glucose with insulin treatment. Materials and methods: Forty-eight patients over the age of 18 years who were admitted to the ED with acute hyperglycemia were included in the study. Serum samples were taken from patients on admission and 6 h after the normalization of blood glucose with insulin treatment, and adiponectin levels were measured in both samples. Results: There were 21 female and 27 male patients with a median age of 58.7 ± 18 years. All patients' blood glucose levels were normalized with insulin treatment according to international recommendations. Serum adiponectin levels decreased significantly after the normalization of blood glucose in the whole group. Adiponectin levels decreased from 28.9 ± 16.5 to 12.1 ± 10.9 µg/mL (P < 0.0001) in the whole group. This decrease was independent of diabetes type and body mass index. Conclusion: Normalization of blood glucose in patients with hyperglycemia caused a decrease in adiponectin levels, independent of diabetes type and/or body weight in an acute emergency setting. Inhibited upregulation of adiponectin secretion and/or blunted suppressive effect of insulin due to hyperglycemia or exogenous insulin administration may have caused the decrease in adiponectin levels.

BACKGROUND: Little is known about the role of advanced glycation end products (AGEs) and their receptor (RAGE) in diabetic cardiovascular complications. Therefore, we aimed to evaluate the association of serum soluble RAGE (sRAGE) levels and left ventricular (LV) diastolic dysfunction in patients with type 2 diabetes. METHODS: Our study consisted of 40 patients with type 2 diabetes and 40 age- and sex-matched healthy control group. Subjects with age ≥ 50 years old and any cardiovascular risk factors or conditions were excluded from the study. Serum sRAGE levels determined by enzyme-linked immunosorbent assay and LV diastolic dysfunction were evaluated according to current American Society of Echocardiography guidelines. RESULTS: Baseline characteristics were similar between groups except body mass index, waist-hip ratio, and fasting glucose levels. Serum sRAGE level was significantly lower in diabetic group compared with control group (676 ± 128 vs. 1044 ± 344, p < 0.05). Diastolic dysfunction was observed in 50% of diabetic patients (40% grade I and 10% grade II). Correlation analysis showed that serum sRAGE was negatively correlated with duration of diabetes, septal E'/A', lateral E'/A', and average E/E'. In multivariate regression analysis, serum sRAGE level was strongly associated with diastolic dysfunction in patients with type 2 diabetes. CONCLUSION: Our study showed that serum sRAGE level was significantly lower in type 2 diabetic patients aged < 50 years old. Also, sRAGE has negative correlation with the duration of diabetes and it was significantly associated with the presence of diastolic dysfunction in type 2 diabetes.

Many hypertensive patients require ≥2 drugs to achieve blood pressure targets. This study aims to review and analyze the clinical studies conducted with dual or triple combination of angiotensin II receptor blockers (ARBs), calcium channel blockers (CCBs), and diuretics. Medical literature between January 1990 and April 2012 was reviewed systematically and data from eligible studies were abstracted. Data were analyzed using random-effects models. Of the 224 studies screened, 7563 eligible patients from 11 studies were included. Triple combinations of ARBs (olmesartan or valsartan), CCBs (amlodipine), and diuretics (hydrochlorothiazide) at any dose provided more blood pressure reduction in office and 24-hour ambulatory measurements than any dual combination of these molecules (P<.0001 for both). Significantly more patients achieved blood pressure targets with triple combinations (odds ratio, 2.16; P<.0001). Triple combinations did not increase adverse event risk (odds ratio, 0.96; P=.426). Triple combinations at any dose seem to decrease blood pressure more effectively than dual combination of the same molecules without any remarkable risk elevation for adverse events. Further prospective studies evaluating the efficacy and safety of triple combinations, especially in the form of single pills, are required.
