Background and Objectives:Patients on oral anticoagulation therapy (OAT) require regular monitoring of the prothrombin time (PT) and dosage adjustment to prevent thromboembolic diseases without the risk of hemorrhage. Portable self PT monitors have been recently developed because the standard PT measurements are complicated and take considerable time. This study compared the International normalized ratio (INR) results that were obtained with using the CoaguChek XS device (Roche Diagnostic, Mannheim, Germany) with those obtained using a standard laboratory method Sysmex CA-1500 (Sysmex Corporation, Kobe, Japan) in the patients on OAT and also a healthy control group. Subjects and Methods:100 outpatients on OAT and 20 healthy controls were enrolled on a volunteer basis after providing informed consent at the Dong-A University Hospital. The outpatients and the healthy control group provided us the INR measurements with using both the CoaguChek XS and the Sysmex CA-1500. Results:The coefficients of variation for CoaguChek XS and Sysmex CA-1500 were less than 10%. The PT (INR) results of CoaguChek XS and Sysmex CA-1500 were 2.0±0.7 and 2.2±0.7, respectively (p<0.001). There was a good correlation between CoaguChek XS and Sysmex CA-1500 (r=0.974, p<0.001). On the regression analysis, the slope of the regression line was 0.9197 and the y-intercept was 0.0058. On the BlandAltman analysis, the INR mean difference (bias) between the two methods (CoaguChek XS INR-Sysmex CA-1500 INR) was -0.2 and the limit of agreement was +0.168~-0.568. Conclusion:The measurement with using CoaguChek XS has high repeatability, rapid availability and good accuracy that are comparable to the standard laboratory method. Therefore, CoaguChek XS can be a valuable tool for the self-monitoring of patients on OAT.
Background: Adipocytes produce several adipokines that modulate insulin action as well as glucose and lipid metabolism. The aim of this study was to evaluate the relationship between serum adiponectin concentrations and metabolic syndrome (MS) in patients with type 2 diabetes mellitus.
Methods: This study included 127 type 2 diabetic patients (males 63, females 64). The subjects were divided into two groups as with or without metabolic syndrome (MS(+) or MS(-)). The MS was diagnosed by International Diabetes Federation. Serum adiponectin, leptin, fasting plasma insulin, glucose, glycated hemoglobin, lipid profile, white blood corpuscle (WBC), aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid and C-reactive protein (CRP) were examined. Results: Serum adiponectin concentrations were significantly lower in MS(+) than MS(-) (4.8 ± 2.4 μg/mL vs 7.6 ± 5.8 μg/mL, 7.6 ± 3.7 μg/mL vs 11.5 ± 7.2 μg/mL, P < 0.05 in males and females). After adjustment for age and body mass index (BMI), in MS (+), the serum levels of adiponectin correlated positively with high density lipoprotein -cholesterol (HDL-C) and negatively with height, body weight, ALT and CRP. In MS(-), the serum levels of adiponectin correlated positively with HDL-C and negatively with diastolic blood pressure (DBP), triglyceride and CRP. By multiple regression analysis, no parameters were independently correlated with serum adiponectin concentrations in MS(+), while DBP and HDL-C were independently related to serum adiponectin concentrations in MS(-). Conclusion: Serum adiponectin concentrations were lower in type 2 diabetic patients with MS than without MS. There were no significant parameters related to decrease serum adiponectin concentrations in MS. But further study is needed to confirm this result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
