AbstractRecent studies implied that low-density lipoprotein (LDL) modified predominantly by oxidation or glycation, significantly contributes to the formation of atherosclerotic lesions. In contrast to oxidized LDL (ox-LDL), high-density lipoprotein (HDL) is able to prevent accumulation of ox-LDL in arterial walls. This antiatherogenic property of HDL is attributed in part to several enzymes associated with the lipoprotein, including HDL-associated paraoxonase 1 (PON1). In this study we analyzed PON1 arylesterase/paraoxonase activities in relation to serum lipid profile, gender and age in thirty clinically healthy Slovak volunteers. Our results showed that PON1 arylesterase and paraoxonase activities were lower in citrated plasma than in serum by 16.6% and 27.3%, respectively. Among serum lipoproteins, only HDL-cholesterol level showed significant positive correlation with PON1 arylesterase activity (p = 0.042). Likewise, we found a significant relationship between atherogenic index (AI = total cholesterol/HDL-cholesterol) and PON1 arylesterase activity (p = 0.023). No significant correlation could be demonstrated between PON1 paraoxonase activity and serum lipid profile, age or gender. Furthermore, it was found that PON1 paraoxonase/arylesterase activities were higher in women compared with both investigated activities in men, but these differences were not statistically significant. These results confirmed a positive correlation between HDL-cholesterol and PON1 arylesterase activity. Moreover, it was found out that PON1 paraoxonase activity is not influenced either by gender or by age. PON1 arylesterase activity was however affected by gender to a limited extent.

The present study was designed to evaluate the association of lipid profile in pre- eclampsia and eclampsia. This case-control study was carried out in the department of biochemistry, M.A.G. Osmani Medical College, Sylhet, during July 2005 to June 2006. Total 100 study subjects were evaluated, 40 normotensive pregnant women (mean age 24.90 ± 4.04) as normal and 60 already diagnosed preeclamptic & eclamptic women (mean age 24.17 ± 4.90) as study group. Age range was 15-45 years, gestational age 24 weeks to term were included. Patients with pre-existing hypertension were excluded. Serum lipid profile (total lipids, cholesterol, triglycerides, HDL-cholesterol and LDLcholesterol) of hundred women with Pre-eclampsia and Eclampsia (n=60), normotensive women (n=40) were monitored. The preeclampsia was associated with a significant rise in triglyceride (225.6 ± 28.93 vs 165.6 ± 17.22) and fall in HDL cholesterol concentration (42.4 ± 9.29 vs 55.7 ± 7.11), while eclamptic women showed significant fall in HDL cholesterol (41.8 ± 8.79 vs 55.7 ± 7.11) and rise in LDL cholesterol (133.4 ± 11.75 vs 115.2 ± 10.72) as compared to normal pregnant women. Lipid metabolism plays a key role in the pathophysiology of Pre-eclampsia and Eclampsia. Increased triglycerides levels along with decreased HDL-cholesterol levels and delayed triglycerides clearance and high blood pressure are associated with development of preeclampsia and eclampsia. This association may be significant in understanding the pathologic processes of preeclampsia and may help in developing strategies for prevention or early diagnosis of the disorder.

A prospective study was conducted in the Northern region of Bangladesh, to investigate the serum lipid profile viz the level of total cholesterol (TC), Triglyceride (TG), HDL-cholesterol and LDL-cholesterol of hypertensive patients and compares them with levels of control subjects. The results revealed that serum total cholesterol, triglyceride and LDL-cholesterol were significantly markedly raised (p>0.001) whereas the level of HDL-cholesterol was significantly lower (p>0.001) in hypertensive patients as compared to control subjects. No significant changes of serum lipid profile were found between male and female hypertensive patients, but in control subjects, markedly higher levels of serum lipid profile was observed in male compared to that of female. It was concluded that hypercholesterolaemia, hypertrigyceridaemia and low density lipoprotein are the main lipid abnormalities on the incidence of hypertension in the study area.

Background: Gallbladder disease is one of the most common gastrointestinal diseases. Various studies have shown association between gallstone and alteration in serum lipids. The objective of this study was to evaluate histological patterns of cholecystectomy specimens and compare serum lipid profile of gallstone patients with controls.Methods: This study was conducted over a period of two years (April 2016 to April 2018). Records of 287 specimens who underwent cholecystectomy were analysed in which gallstones were found only in 186 patients. Out of 186 patients with gallstones, records of serum lipid profile were available in 32 patients which were compared with 32 control of similar age. Independent t- test was used to compare the data between cases and control.Results: Out of 287 cases, 68 were male and 219 were female with male to female ratio of 1:3.2. The predominant histopathological lesion was chronic cholecystitis (73.17%). Malignancy was observed in 0.7% cases. Serum total cholesterol, triglycerides and low density lipoprotein cholesterol were found to be higher and statistically significant in patients with gallstone compared to controls (p value 0.024, <0.001and 0.016 respectively). Serum High density lipoprotein cholesterol was lower in gallstone patient than in control but not statistically significant (p value 0.23).Conclusions: Chronic cholecystitis was the most common histopathological lesion. Serum total cholesterol, triglyceride and low density lipoprotein cholesterol level were elevated and statistically significant in patients with gallstone.

Abstract Background The study was done to assess high-density lipoprotein (HDL) functionality and to correlate this with paraoxonase 1 (PON1) activity in malnourished children. It aimed to find the effect of malnutrition on changes in PON1 activity, HDL functionality, lipid profile and lipid hydroperoxide formation. Methods This case control study included 30 malnourished children (up to age 5 years) and 30 healthy controls in the paediatric inpatient department of SRTR Government Medical College Ambajogai, India. Clinically diagnosed cases depending on anthropometric indices were selected. Serum PON1 activity by using phenyl acetate as a substrate, HDL functionality by haemin by its protection on H2O2 and haemin induced LDL oxidation, lipid profile by routine enzymatic methods and lipid hydroperoxide using the FOX2 assay were measured. Results Malnourished children had significantly decreased PON1 activity (106.6 ± 12.74** vs. 132.23 ± 28.49 IU/L), HDL functionality (116.55 ± 8** vs. 132.29 ± 10.9%), total cholesterol (TC) (102.5 ± 16** vs. 116.4 ± 12.65 mg/dL), HDL-cholesterol (C) (33.41 ± 9.74** vs. 40.55 ± 5.85 mg/dL) and reduced total protein level (5.56 ± 0.91* vs. 6.06 ± 1.055) higher triglycerides (TG) (146.76 ± 34.97* vs. 125.96 ± 17.21 mg/dL) level and total hydroperoxide (TPX) levels (5.568 ± 1.70** vs. 3.22 ± 1.52 μM/L). *p < 0.05 **p < 0.001. PON1 activity (r2 = 0.576) and TC (r2 = 0.567) shows significant positive correlation with HDL functionality. PON1 activity, HDL-C, HDL functionality and TPX shows independent contribution towards malnutrition in children in multivariate and univariate logistic regression. TC lost its significance in multivariate regression. Conclusions Malnutrition leads to decrease in HDL functionality and increase in hydroperoxide levels with a decrease in PON1 activity.

Background. Some studies suggest a significant relationship between Helicobacter pylori infection and atherogenesis; but the mechanism of the relationship is almost unknown. The current study aimed at evaluating the relationship between H. pylori infection and serum lipid profile. Patients and Methods. The current study was conducted on 2573 patients, from 2008 to 2015. The serum anti-Helicobacter pylori antibody titer and serum lipid profile were assessed in the study population; data were statistically analyzed by SPSS version 16. P values < 0.05 were considered significant. Results. In the current study, 66.5% of the cases were serologically positive for H. pylori. Among male cases, the level of low density lipoprotein (LDL) was higher in patients with H. pylori infection, compared with that of the ones without the infection (P=0.03); although level of triglyceride (TG) was higher and the level of high density lipoprotein (HDL) was lower in the cases with H. pylori infection; there was no statistically significant difference between the cases with and without H. pylori infection regarding the level of HDL and TG. Among female cases, the level of TG was significantly lower in patients with H. pylori infection, compared with that of the ones without the infection (P=0.001); but there was no significant difference between the cases with and without H. pylori infection regarding the level of LDL and HDL. The mean fasting blood sugar (FBS) in the cases with H. pylori infection was significantly higher than that of the ones without the infection (P=0.04). Conclusion. According to the results of the current study, the levels of LDL and FBS were high among the male cases with H. pylori infection. However, in females with H. pylori infection the level of TG was low; hence, it seems that the atherogenicity of H. pylori affected the level of blood sugar more.

Background. This study investigates the effects of Brazil nut ingestion on serum lipid profile in healthy volunteers.Methods. Ten healthy subjects were enrolled in the study. Each subject was tested 4 times in a randomized crossover in relation to the ingestion of different serving sizes of the Brazil nut: 0, 5, 20, or 50 g. At each treatment point, peripheral blood was drawn before and at 1, 3, 6, 9, 24, and 48 hours and 5 and 30 days. Blood samples were tested for total cholesterol, high- and low-density lipoprotein cholesterol (HDL-c and LDL-c, resp.), triglycerides, selenium, aspartate and alanine aminotransferases, albumin, total protein, alkaline phosphatase, gamma GT, urea, creatinine, and C-reactive protein.Results. A significant increase of the plasma selenium levels was observed at 6 hours within the groups receiving the nuts. Serum LDL-c was significantly lower, whereas HDL-c was significantly higher 9 hours after the ingestion of 20 or 50 g of nuts. The biochemical parameters of liver and kidney function were not modified by ingestion of nuts.Conclusions. This study shows that the ingestion of a single serving of Brazil nut can acutely improve the serum lipid profile of healthy volunteers.

Background:Tamoxifen acts as a selective estrogen receptor modulator by binding to the estrogenreceptors on mammary epithelium andblockingtheproliferative action of estrogen on mammaryepithelium. In contrast to that it has a weak estrogen agonistic effect on bone, liver and endometrium.Tamoxifen therapy has favorable effects on serum lipid profile by decreasing serum levels of Total cholesterol and low density lipoprotein (LDL), while its effect on high density lipoprotein (HDL) and triglyceride (TG)is still controversial. So this study is to evaluate the effects of tamoxifenTherapy on fasting serum lipid profile in patients with breast cancer. Results: Mean age was 43.56±3.53yrs , most common BMI was 30-34.9. Patient serum TG levels were raised from baseline after 3 months of tamoxifen with p values of (0.000) which was statistically significant while HDL levels were raised but with p value of (0.008 ) which was statistically insignificant. Serum LDL and total cholesterol were reduced from baseline after 3 month with p value of (0.000) and (0.000) respectively. Conclusion: This study concludes that tamoxifen has effects on serum lipid profile by increasing TG levels and lowering TC and LDL levels so this should be in consideration while prescribing tamoxifen to the patients having other risk factors for cardiovascular abnormalities.

AbstractObjectives. Diabetes mellitus is associated with dyslipidemia, which contributes to a higher risk of thrombosis, atherosclerosis and cardiovascular disease. This study evaluated the effects of leucine and resistance training on the serum lipid profile in rats with streptozotocin-induced diabetes for 8 weeks.Methods. Wistar rats with neonatal streptozotocin-induced diabetes were treated with leucine supplementation (5%) and/or resistance training (3 days per week) for 8 weeks, and divided in DL (diabetic and leucine), DT (diabetic and resistance training group) and DLT (diabetic, leucine and resistance training) groups. Others 2 groups of animals received isonitrogen AIN-93M diet that was defined as a control diet: group D (diabetic untreated) and group C (non-diabetic).Results. The decrease in serum total cholesterol and increase in high-density lipoprotein cholesterol (HDL-C) was observed in the resistance training-induced diabetic rats when compared with diabetic rats. There was no change in serum lipid profile in leucine-supplemented diabetic rats and no synergistic effect of leucine and resistance training. The fasting glucose levels were reduced in all animals treated compared to D group.Conclusion. The diabetic trained rats demonstrate a protective effect of resistance training on the serum lipid profile.
