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

Abdominal adiposity has a central role in developing insulin resistance (IR) by releasing pro-inflammatory cytokines. Patients with metabolic syndrome (MS) have higher values of homocysteine. Hyperhomocysteinemia correlates with IR, increasing the oxidative stress. Oxidative stress causes endothelial dysfunction, hypertension and atherosclerosis. The objective of the study was to examine the correlation of homocysteine with siMS score and siMS risk score and with other MS co-founding factors. The study included 69 obese individuals (age over 30, body mass index [BMI] >25 kg/m2), classified into two groups: I-with MS (33 patients); II-without MS (36 patients). Measurements included: Anthropometric parameters, lipids, glucose regulation parameters and inflammation parameters. IR was determined by homeostatic model assessment for insulin resistance (HOMA-IR). ATP III classification was applied for diagnosing MS. SiMS score was used as continuous measure of metabolic syndrome. A significant difference between groups was found for C-reactive protein (CRP) (p<0.01) apolipoprotein (Apo) B, HOMA-IR and acidum uricum (p<0.05). siMS risk score showed a positive correlation with homocysteine (p=0.023), while siMS score correlated positively with fibrinogen (p=0.013), CRP and acidum uricum (p=0.000) and homocysteine (p=0.08). Homocysteine correlated positively with ApoB (p=0.036), HbA1c (p=0.047), HOMA-IR (p=0.008) and negatively with ApoE (p=0.042). Correlation of siMS score with homocysteine, fibrinogen, CRP and acidum uricum indicates that they are co-founding factors of MS. siMS risk score correlation with homocysteine indicates that hyperhomocysteinemia increases with age. Hyperhomocysteinemia is linked with genetic factors and family nutritional scheme, increasing the risk for atherosclerosis. © 2018 Walter de Gruyter GmbH, Berlin/Boston.
