Abstract
CONTEXT Myeloperoxidase is a heme protein secreted by activated macrophages and generates intermediates that oxidize lipoproteins. Myeloperoxidase-463G/A is a functional polymorphism involved in regulation of myeloperoxidase expression. OBJECTIVE The aim of this study is to assess the relation of myeloperoxidase-463G/A polymorphism with metabolic syndrome and its component traits in Egyptian women from the Suez Canal area. METHODS The study includes 100 healthy female subjects and 100 metabolic syndrome patients. The component traits of metabolic syndrome are determined and the genotypes of the polymorphisms assessed using the PCR-RFLP technique. RESULTS There was no significant difference in the allele frequencies between the metabolic syndrome and control groups. However, the GA and AA genotypes were associated with lower total cholesterol, LDL-C, systolic and diastolic blood pressure in the patients. CONCLUSION Myeloperoxidase-463G/A polymorphism is not associated with the incidence of metabolic syndrome.

Association of myeloperoxidase with total and cardiovascular mortality in individuals undergoing coronary angiography--the LURIC study. Int J Cardiol 2014; 174:96-105.

Abstract
Background The phagocytic enzyme myeloperoxidase (MPO) acts as a front-line defender against microorganisms. However, increased MPO levels have been found to be associated with complex and calcified atherosclerotic lesions and incident cardiovascular disease. Therefore, this study aimed to investigate a predictive role of MPO, a biomarker of inflammation and oxidative stress, for total and cardiovascular mortality in patients referred to coronary angiography. Methods and results MPO plasma concentrations along with eight MPO polymorphisms were determined in 3036 participants of the Ludwigshafen Risk and Cardiovascular Health study (median follow-up 7.75 years). MPO concentrations were positively associated with age, diabetes, smoking, markers of systemic inflammation (interleukin-6, fibrinogen, C-reactive protein, serum amyloid A) and vascular damage (vascular cellular adhesion molecule-1 and intercellular adhesion molecule-1) but negatively associated with HDL-cholesterol and apolipoprotein A-I. After adjustment for cardiovascular risk factors MPO concentrations in the highest versus the lowest quartile were associated with a 1.34-fold risk (95% CI: 1.09–1.67) for total mortality. In the adjusted model the hazard ratio for cardiovascular mortality in the highest MPO quartile was 1.42 (95% CI: 1.07–1.88). Five MPO polymorphisms were positively associated with MPO concentrations but not with mortality. Using Mendelian randomization, we did not obtain evidence for a causal association of MPO with either total or cardiovascular mortality. Conclusions MPO concentrations but not genetic variants at the MPO locus are independently associated with risk for total and cardiovascular mortality in coronary artery disease patients.
