    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 mu g/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.

    Elective percutaneous coronary intervention leads to significant changes in serum resistin, leptin, and adiponectin levels regardless of periprocedural myocardial injury: an observational study

    Objective: Bioactive roles of adipokines in coronary atherosclerosis and acute coronary syndromes have been demonstrated previously. Ho-wever, there is a lack of data regarding the relationship between serum adipokines and periprocedural myocardial injury (PMI) following elective percutaneous coronary intervention (PCI). Therefore, we aimed to investigate the association between serum adipokines and PMI related to elective PCI. Methods: In total, 153 consecutive patients (aged 60.6 +/- 8.2 years, 98 men) with stable angina pectoris undergoing elective PCI were enrolled in this observational cross-sectional study. Serum resistin, leptin, adiponectin, and high-sensitive Troponin T (hscTnT) levels were measured immediately before PCI and after 12-h PCI. The no-injury, PMI, and type 4a myocardial infarction (type 4a MI) groups were defined as groups consisting patients with post-procedural hscTnT concentrations < 14 ng/L, between 14-70 ng/L, and > 70 ng/L, respectively. Results: Serum hscTnT, resistin, and leptin concentrations significantly (p<0.001) increased while serum adiponectin levels decreased (p<0.001) after 12-h elective PCI. However, no correlation was found between post-procedural hscTnT concentrations and resistin, leptin, and adiponectin levels. The no-injury group consisted of 65 patients (42.4\%), whereas PMI and type 4a MI were observed in 70 (45.8\%) and 18 (11.8\%) patients, respectively. The average pre-procedural and post-procedural resistin, leptin, and adiponectin levels did not show any significant difference in the no-injury, PMI, and type 4a MI groups. Conclusion: There is no correlation between serum adipokine levels and post-procedural troponin elevations reflecting PMI or type 4a MI. However, serum resistin and leptin levels increase, whereas adiponectin levels decrease significantly after elective PCI.

    Endotrophin as a novel marker in PCOS and its relation with other adipokines and metabolic parameters: a pilot study

    Background: Polycystic ovary syndrome is known to be the most common hormonal disorder in women of reproductive age. Current evidence shows that regulatory proteins secreted from the adipose tissue called adipokines may have a role in polycystic ovary syndrome. We planned to investigate the role of endotrophin that has never been researched in polycystic ovary syndrome before and its correlation with other metabolic parameters and adipokines such as adiponectin and ghrelin in patients with polycystic ovary syndrome. Methods: Forty-three women (n: 43) with polycystic ovary syndrome and 43 (n: 43) women as a control group were enrolled in this cross-sectional study. Serum levels of endotrophin, adiponectin, and ghrelin levels were measured with the enzyme-linked immunosorbent assay method. High-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol levels, luteinizing hormone/follicle-stimulating hormone ratio, total testosterone, and triglyceride levels were measured. Homeostasis model assessment for insulin resistance index, body mass index, Ferriman Gallwey Score, and waist-to-hip ratio were also evaluated. Results: Total testosterone, homeostasis model assessment for insulin resistance, C-reactive protein, luteinizing hormone/follicle-stimulating hormone ratio, and triglyceride levels were higher in patients with polycystic ovary syndrome (p < 0.01). No difference was detected between the groups in terms of body mass index, Ferriman Gallwey Score, waist-to-hip ratio, total cholesterol, low-density lipoprotein, and high-density lipoprotein levels (p > 0.05). We did not observe any significant difference in adiponectin and ghrelin levels between the groups (p > 0.05). Patients with polycystic ovary syndrome had significantly higher endotrophin levels (p < 0.01). According to our regression analyses {[}area under the curve: 0.973 (0.935-1.000), 95\% confidence interval, 95.2\% sensitivity, and 100\% specificity], it was shown that endotrophin greater than 92 ng/ml and homeostasis model assessment for insulin resistance greater than 2.5 might be good predictors for polycystic ovary syndrome diagnosis. Conclusion: We demonstrated that endotrophin level is higher in patients with polycystic ovary syndrome and may have predicted polycystic ovary syndrome with increased homeostasis model assessment for insulin resistance index. There was no significant difference in adiponectin and ghrelin levels in the polycystic ovary syndrome group. Endotrophin may have a role in polycystic ovary syndrome etiology rather than other adipokines.
