Background It has been documented that patients with metabolic syndrome (MS) and vascular complications have higher homocysteine levels. Hyperhomocysteinemia correlates with IR, increasing oxidative stress, which causes lesions of vascular endothelium leading to endothelial dysfunction, hypertension and atherosclerosis. Objective The objectives of the study were to examine homocysteine values, along with cardiovascular risk factors (lipid and apolipoprotein status, CRP, blood pressure), indicators of renal function (microalbuminuria/24 h), glucose regulation and insulin resistance (glucose and insulin level, HbA1c, HOMA-IR, uric acid) and anthropometric parameters (BMI, WC, HC, WHR) in patients with and without MS as a correlation between homocysteine and MS factors. Methods The study included obese and overweight individuals, aged of 30–75 yrs. classified into two groups: with MS (n = 35) and without MS (n = 41). Results Patients with MS had increased WC, BMI, BP, glycaemia, HOMA-IR, TG, CRP, microalbuminuria, homocysteine and decreased HDL-C (p < 0.05). Statistically significant difference between groups was found for WC, BMI, sBP and dBP, TG, HDL-C (p < 0.01) and glycaemia, CRP, Apo B, HOMA-IR (p < 0.05). Significant positive correlations were found between homocysteine and sBP (p = 0.036), dBP (p = 0.04), Apo B (p = 0.038) and hyperlipoproteinemia (type IIa, type IIb and type IV) (p = 0.04). Conclusion Patients with MS had increased abdominal obesity, hypertension, hypertriglyceridemia, inflammation factors, IR, homocysteine and microalbuminuria as markers of endothelial dysfunction. A correlation between homocysteine and hypertension and hyperlipoproteinemia showed that homocysteine could be used as a potential marker for atherosclerosis progression. © 2016

Objective: The aim of this study was to investigate the association between metabolic syndrome and liver enzymes in overweight and obese adolescents and young adults. Methods: A total of 126 overweight and obese adolescents and young adults (age, 15-26 years), 55 (43.6%) with metabolic syndrome and 71 (56.4%) without metabolic syndrome, were studied. Results: Patients with metabolic syndrome had significantly higher alanine aminotransferase (ALT), γ-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP) levels compared to patients without metabolic syndrome [36.5±22.2 vs. 29.4±17.8 IU/L (P=0.043), 33.8±17.8 vs. 26.9±18.4 IU/L (P=0.002), and 84.3±32.2 vs. 75.7±29.5 IU/L (P=0.063)]. Aspartate aminotransferase (AST) levels were similar in both groups (24.1±9.8 vs. 23.3±9.0 IU/L, P=0.674). Elevated AST, ALT, GGT, and ALP levels were observed in 6, 15, 18, and 5 patients (11%, 27%, 14%, and 9%) with metabolic syndrome compared to 6, 17, 6, and 4 (8%, 24%, 8% and 5%) patients without metabolic syndrome (P=0.872, P=0.826, P<0.001, and P=0.035). In multivariate regression models adjusted for age and gender, metabolic syndrome was not a significant predictor of ALT (P=0.967), GGT (P=0.526), and ALP levels (P=0.221), but insulin resistance was a significant predictor for ALT and GGT levels (P=0.001, P=0.028). Conclusion: Changes in liver function tests were observed in obese patients with metabolic syndrome, compared to patients without metabolic syndrome, especially in ALT and GGT levels. Insulin resistance is an independent pathogenic mechanism in liver function test changes regardless of metabolic syndrome in nondiabetic centrally obese youth. © Copyright 2013, Mary Ann Liebert, Inc. 2013.
