Oxidative stress and antioxidants in patients with cardiogenic shock complicating acute myocardial infarction

BACKGROUND: Lipid peroxidation and derived oxidized products are being intensively investigated because of their potential to cause injury and because of their pathogenic role in several diseases. The view that an excess of lipid peroxidation products is present and is relevant in the pathogenesis of cardiogenic shock-induced damage has still not received definitive support. METHODS: To evaluate the extent of lipid peroxidation, the status of enzymatic and nonenzymatic antioxidants in patients with cardiogenic shock that complicate acute myocardial infarction (AMI) and to compare with normal subjects. RESULTS: Compared with normal subjects, cardiogenic shock patients had higher malondialdehyde, conjugated dienes and reduced activities of erythrocyte antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lower concentrations of reduced glutathione (GSH) in erythrocyte and in plasma GSH, vitamin C, vitamin E and in beta-carotene. CONCLUSIONS: Cardiogenic shock is associated with greater than normal lipid peroxidation and with an imbalance in antioxidants' status. These results indicate that low activities of SOD, CAT, GPx and low concentrations of GSH, vitamin C, vitamin E and beta-carotene in the circulation of patients with cardiogenic shock complicating AMI may be due to increased utilization to scavenge lipid peroxides. Decrease in plasma concentrations of GSH, vitamin E and beta-carotene seems to be responsible for the elevation of lipid peroxidation in cardiogenic shock complicating AMI compared with MI.     

Lipid profile, oxidant-antioxidant status and glycoprotein components in hyperlipidemic patients with/without diabetes

BACKGROUND: Plasma lipoproteins are protected against oxidative modification by the antioxidant defense system. An imbalance in the antioxidant defense system seems to result from the accumulation of low density lipoprotein (or) very low density lipoprotein in the course of hyperlipidemia. METHODS: The lipid profile, glycoprotein components, glucose, total proteins, albumin, lipid peroxidation and antioxidant status of plasma and erythrocytes were investigated in hyperlipidemic patients and hyperlipidemic patients with diabetes on treatment with glibenclamide (or) glipizide along with normal subjects and compared. RESULTS: A significant increase was observed in the levels of total cholesterol (TC), VLDL-C, triglycerides (TG), lipid peroxidation, ceruloplasmin (CP), glycoprotein components and glucose in the hyperlipidemic patients with/without diabetes and the increase was more pronounced (except TC) in patients with diabetes. The activities of erythrocyte antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and plasma concentrations of vitamins C and E, and reduced glutathione (GSH) decreased in hyperlipidemic patients with/without diabetes. GPx, CAT, vitamin C and GSH levels exhibited a further decrease in hyperlipidemic patients with diabetes. CONCLUSION: An enhanced levels of VLDL-C, TC/HDL-C ratio, TG, lipid peroxidation, glycoprotein components, and decreased concentrations of total proteins (TPs) and albumin were observed in hyperlipidemic patients with diabetes while the decrease was more marked in GSH, vitamin C, CAT and GPx among antioxidants.     

Circulating lipid peroxidation and antioxidant status in cervical cancer patients: a case-control study

Objectives: The present case-control study was conducted to investigate the status of circulating lipid peroxidation and the enzymic and nonenzymic antioxidants of cervical cancer patients.

Design and methods: Plasma thiobarbituric acid reactive substances (TBARS), conjugated dienes (CD) and the levels of antioxidants such as reduced glutathione (GSH), glutathione peroxidase (GPx), glutathione-S-transferase (GST), superoxide dismutase (SOD), vitamin C and vitamin E were estimated in circulation of thirty patients and an equal number of age matched normal subjects as control.

Results: Significantly elevated levels of plasma TBARS and CD and significantly lowered levels of GSH, GPx, GST, SOD vitamin C and vitamin E were observed in cervical cancer patients as compared to controls. Our study reveals increased lipid peroxidation and possible breakdown of antioxidant status in patients with cervical carcinoma.

Conclusion: These results indicate that low levels of GSH, GPx, GST, SOD, vitamin E and vitamin C in the circulation of cervical cancer patients may be due to their increased utilization to scavenge lipid peroxides as well as their sequestration by tumor cells. Malnutrition may also be a significant cause for the increased prevalence of cervical cancer in women with a low socioeconomic status.

Role of selenium in reducing hypoxia-induced oxidative stress: an in vivo study.

At high altitudes, the reactive oxygen species are continuously generated as a consequence of low oxygen partial pressure (hypoxia), which causes tissue damage. The body's defence system to combat the oxidative stress (e.g., anti-oxidant enzymes, free radical scavengers such as vitamin C, vitamin E, beta-carotene, reduced glutathione and minerals such as selenium, etc.) may diminish. In the present study, the antioxidant effect of selenium (Se) in reducing the hypoxia-induced oxidative stress was evaluated by exposing male albino rats to hypoxic stress in a decompression chamber. Exposure to hypoxia resulted in an increase in malondialdehyde (MDA) levels in plasma and tissues and a concurrent decrease in blood glutathione (GSH), glutathione peroxidase (GPx), plasma protein and plasma selenium content when compared with controls. Haemoglobin concentration (Hb%), red blood corpuscles (RBC) and white blood corpuscles (WBC) count were also increased in the hypoxia-exposed group. Selenium supplementation to animals reversed the trend. There was a significant decrease (P < 0.001) in MDA and subsequent increase in plasma and tissue GSH levels. Similarly the blood and tissue GPx and plasma protein also increased significantly in the Se supplemented animals compared with control animals. The Hb%, RBC and WBC counts showed no significant difference between Se-fed and control rats. These results suggest that selenium may help in reducing the lipid peroxidation during hypoxia.

n -- 3 fatty acid supplementation during pregnancy in women with allergic disease: effects on blood pressure, and maternal and fetal lipids

n--3 Fatty acids derived from fish oil reduce plasma triacylglycerols (triglycerides) and increase HDL-C (high-density lipoprotein cholesterol); however, the effect of n--3 fatty acid supplementation during pregnancy, a hyperlipidaemic state, remains unknown. We took the opportunity to investigate maternal lipid levels and blood pressure during and after pregnancy, and fetal lipid levels at birth, in a study that aimed primarily to examine the effect of fish oil supplementation during pregnancy on immune function in infants born to women with allergic disease. Eighty-three pregnant women who had allergic disease, but were otherwise healthy, completed the study. They were randomly allocated to receive fish oil or olive oil capsules, taken as 4 g/day, from 20 weeks of pregnancy until delivery. Compared with olive oil, fish oil supplementation did not alter triacylglycerols, total cholesterol, LDL-C (low-density lipoprotein cholesterol) or HDL-C during or after pregnancy. There was also no effect of fish oil on cord blood triacylglycerols, total cholesterol, LDL-C or HDL-C. Fish oil supplementation during pregnancy did not alter maternal blood pressure during or after pregnancy. The effects of fish oil on lipids and blood pressure in non-pregnant individuals appear to be lost when it is administered during pregnancy.

Plasma homocyst(e)ine,folate and vitamin B(12) levels among school children in Taiwan: The Taipei Children Heart Study

OBJECTIVE: The purpose of this study is to examine the association of plasma Hcy, folate and vitamin B(12) levels on CVD risk factors among children in Taiwan. METHODS: After multistage sampling, we selected randomly 1,235 children (609 boys and 626 girls) aged 12 to 15 yr. Plasma Hcy levels was measured using ABBOTT Imx analyzer, while plasma folate and vitamin B(12) were measured using ACS: 180 automated chemiluminescence analyzer. Anthropometric, blood pressure (BP) and other biochemical CVD risk factors including serum total cholesterol (CHOL), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), apolipoprotein A1 (apoA1) and B (apoB) and lipoprotein(a) [Lp(a)]were measured using standard methods. We also calculated low density lipoprotein-cholesterol (LDL-C) and TCHR (total cholesterol to HDL-C ratio) as atherogenic indices. RESULTS: Boys were taller and heavier, having higher body mass index (BMI), systolic blood pressure (SBP) and plasma glucose levels but lower diastolic blood pressure (DBP), heart rate (HR), cholesterol, TG, HDL-C, LDL-C, TCHR, and Lp(a) levels than girls. Boys also had higher plasma Hcy and lower folate, vitamin B(12), levels than girls (for plasma Hcy, mean +/- SD, 10.50 +/- 4.13 vs. 8.95 +/- 2.61 micromol/L for boys vs. girls, respectively). Plasma Hcy levels were significantly correlated positively with body height, body weight, SBP and DBP in both genders. Body height, body weight, BMI and SBP levels were found to increase with trend among different quintile plasma Hcy subgroups on boys but not on girls. Plasma folate and vitamin B(12) were decreased significantly along with the higher quintile plasma Hcy subgroup in both genders. CONCLUSIONS: Boys had higher plasma Hcy levels than girls after adjusting for age. Furthermore, plasma Hcy levels were significantly associated with anthropometric parameters, such as body height and weight and blood pressure, but not related with lipid profiles among children in Taiwan.
