PESQUISA DE MIELOPEROXIDASE E OUTROS MARCADORES LABORATORIAIS NA GESTAÇÃO

Abstract

During pregnancy, some physiological changes occur in women, mostly lipid changes and development of insulin resistance. Probably, these changes are associated with increased hepatic effect of estradiol, progesterone and placental lactogen during this period, because progestins are known to alter the profile of LDL cholesterol and decrease the activity of hepatic lipase. The occurrence of such changes can indicate increased risk in these women, in developing atherogenic diseases in the future. Furthermore, this population also noted an increase in the number of neutrophils and monocytes into the peripheral circulation, especially of women with preeclampsia which has the consequence that the production and secretion mechanism of myeloperoxidase (MPO). Thus, it becomes important to investigate metabolic and inflammatory changes which occur during pregnancy, to assist in the diagnosis and prognosis of future cardiovascular disease in these individuals and myeloperoxidase can be studied as a novel biomarker associated with cardiovascular risk and occurrence of oxidative stress. Addition of serum MPO, the determination of the total antioxidant capacity and identification of other laboratory abnormalities, such as markers of inflammation (CRP, alpha-1-acid glycoprotein and leukocytes) for the prevention, diagnosis and treatment of possible future cardiac events or markers such as glycosylated hemoglobin (HbA1c) and glucose to identify the occurrence of gestational diabetes, are useful in assessing the quality of life of the pregnant woman and the developing fetus. Thus, the aim of this study was to evaluate biochemical and immunological for correlation with cardiovascular risk in pregnant women each trimester parameters. Total cholesterol, triglycerides, serum total antioxidant capacity (ABTS), compared ABTS/albumin, total protein, acid uric: results statistically different between the control (non-pregnant) and pregnant women (first, second and third quarter) the following parameters were obtained acid uric and leukocytes. Elevated levels of CRP between groups of pregnant women, which qualifies as a useful parameter for laboratory monitoring of pregnancy, were observed. However, no significant changes in MPO levels, which thus appears to be a suitable for risk prediction of cardiovascular disease in pregnant women were observed marker.
