Dyslipidemia and oxidative stress are both considered to be factors involved in cardiovascular disease; however, the relationship between them has been little explored. In this work, we studied the association between the lipid profile and the activity of antioxidant enzymes such as paraoxonase-1 (PON1), superoxide dismutase 1 (SOD1), ceruloplasmin, and catalase, as well as total antioxidant capacity (the ferric-reducing ability of plasma (FRAP)), in 626 volunteers without cardiovascular disease. Their lipid profile was evaluated, and they were classified as having or not having high triglycerides (↑TG), high low-density cholesterol (↑LDLC), and low high-density cholesterol (↓HDLC), resulting in eight groups: Without dyslipidemia, ↑TG, ↑LDLC, ↓HDLC, ↑TG↑LDLC, ↑TG↓HDLC, ↑LDLC↓HDLC, and ↑TG↑LDLC↓HDLC. When comparisons by group were made, no significant differences in the activity of antioxidant enzymes were obtained. However, the linear regression analysis considering the potential interactions between ↑TG, ↑LDLC, and ↓HDLC suggested a triple interaction between the three lipid profile alterations on the activity of PON1 and a double interaction between ↑TG and ↑LDLC on ferroxidase-ceruloplasmin activity. The analysis presented in this work showed an association between the lipid profile and antioxidant-enzyme activity and highlighted the importance of considering the interactions between the components of a phenomenon instead of studying them individually. Longitudinal studies are needed to elucidate the nature of these associations.

This study was conducted to assess serum lipids in normal people in relation with their total antioxidant status. Altogether 50 fasting blood samples were collected for study in age between 20-50 years. Fasting lipid profile was determined with enzymatic method i.e. triglyceride (TG), high density lipo-protein (HDL) and low density lipo-protein (LDL) whereas total cholesterol (TC) by chemical method using FeCl3 reagent. The antioxidant status was determined by Ferric Reducing Ability of Plasma (FRAP) assay using TPTZ solution. The statistical analysis was done by SPSS program using Pearson’s correlation coefficient. TG showed negative significant correlation with total antioxidant status (p<0.01) and HDL showed positive significant correlation (p<0.05). Whereas TC and LDL showed non-significant correlation with total antioxidant status (p>0.05).DOI: http://dx.doi.org/10.3126/jncs.v27i1.6440 J. Nepal Chem.

Paraoxonase 1 (PON1) seems to have a relevant role in detoxifying processes and in atherosclerosis. The aim of this study was to determine PON1 activity, the total antioxidant capacity, as well as entire lipid profile in children for screening of possible risk of atherosclerosis development. Serum PON1 arylesterase/paraoxonase activities were determined spectrophotometrically. The total antioxidant capacity of the serum was measured by TEAC method. Parameters of lipid profile were analyzed by routine laboratory methods. It has been shown that PON1 arylesterase/ paraoxonase activities were very similar to values found in adults. In children, no significant correlation between PON1 arylesterase activity and HDL was observed. PON1 paraoxonase activity correlated only with atherogenic index. PON1 arylesterase activity was significantly higher in girls than in boys. The antioxidant capacity was inversely related to the body mass index. In this study, PON1 activity was determined in healthy children aged 11 to 12 years and we found a similarity in PON1 activities of children and adults. Moreover, the results of our study support the hypothesis that higher body weight of children may contribute to a greater risk for development of atherosclerosis in which oxidative stress plays a role.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction  Cardiovascular disease (CVD) is recognized as a major public health issue and remains the leading cause of mortality worldwide. There is a clear association between adiposity, blood lipid profile, and adherence to the Mediterranean diet (MD) with the risk of CVD. However, the assessment of body composition parameters, dietary patterns and nutritional intervention in CVD patients undergoing a cardiovascular rehabilitation (CR) program remains insufficient.  Purpose  to characterize body composition, lipid profile and MD adherence in patients with CVD who were attending an exercise-based CR program during COVID-19 era.  Methods  The study was developed between October 2020 and January 2021 in a phase III centre-based CR program. Body composition was assessed by dual energy x-ray absorptiometry Hologic Explorer-W. Adherence to the MD was assessed by the 14-item MD questionnaire. Fasting blood sample was taken for measurement of lipid profile.  Results  A sample of 41 patients (mean age 64.4 ± 7.9 years, 87.8% male) was evaluated. The most prevalent CVD were coronary artery disease (89.5%) and heart failure (21.1%). The main CVD risk factors at admission in the CR program were dyslipidaemia (71.1%), hypertension (68.4%), physical inactivity (26.3%) and diabetes mellitus (21.0%). In our sample the mean body mass index was 28 ± 3.8 kg/m2, being most patients overweight (75.6%), and having a substantially increased risk of metabolic complications (85.3%) accordingly to waist-hip ratio. Body composition assessment showed that 14.6% of the patients had a body fat mass index above 90th percentile. Although only 9.8% of the patients had reduced fat free mass, 17.1% showed appendicular lean mass below the reference value. In addition, less than one third of the patients (31.7%) revealed a high adherence to the MD pattern. A sub-analysis on blood lipids (n = 26) showed that most patients had levels of LDL cholesterol (76.9%) and non-HDL cholesterol (65.4%) above the therapeutic target and 15.4% had triglycerides higher than 150 mg/dl.  Conclusion  Body composition, lipid profile and dietary patterns, play a major role in CVD secondary prevention. Our findings showed that a substantial number of CVD patients, in COVID-19 era, did not have optimal body composition, were above lipid profile targets, and had a low/medium adherence to the MD. Thus, this study highlights the relevance of nutrition on cardiometabolic status and demonstrates the crucial role of nutritional intervention as an integrated part of a long-term phase III CR program. Moreover, further research about nutritional intervention in patients undergoing CR is warranted.

Background:Attention is drawn to the frequent combination of osteoarthritis (OA) with cardiovascular disease. Non-specific inflammation plays a significant role in the pathogenesis of OA and atherosclerosis. Limiting the physical activity of patients with OA is an additional important factor aggravating the course of cardiovascular disease (CVD). Chronic pain syndrome, causing a neuroendocrine response, is often the cause of the development of complications of atherosclerotic disease. Dyslipidemia is the main cause of atherosclerosis and vascular thrombosis.Objectives:To study variants of lipid metabolism disorders in female and male patients of different age groups with osteoarthritis.Methods:Case histories of 90 patients with OA were analyzed. The average age of patients was 63.27 ± 11.31 years. The average body mass index (BMI) is 39.8 ± 3.2. All patients underwent questionnaires, general clinical and biochemical blood tests with lipid profile determination, anthropometry, bioimpedansometry, and the main metabolic rate assessment using indirect calorimetry in dynamics (at the beginning of the study and after 3 months).Results:Burdened heredity for obesity, arterial hypertension (AH), diabetes mellitus (DM) was revealed. AH was diagnosed in 76 patients (84.4%), type II diabetes in 17 (18.9%), dyslipidemia and hypercholesterolemia in 56 (62.2%). Statins were taken by 43 patients (47.8%) - group I patients, which is associated with low adherence to therapy, group II included patients who did not initially take statins or stopped taking them at least 6 months before inclusion in the study.Against the background of diet therapy and physiotherapy exercises, BMI (R0.99; p <0.05), fat mass (R0.95; p <0.05) significantly decreased, lipid profile normalization was noted: total cholesterol (R0.66; p <0 .05), LDL (R0.69; p <0.05), HDL (R0.95; p <0.05), TG (R0.57; p <0.05), AST decreased (R0.64; p <0.05) and ALT (R0.76; p <0.05) in both groups of patients, regardless of lipid-lowering therapy. A decrease in fat mass correlated with TG levels (R0.51; p <0.05), an increase in skeletal muscle mass (R0.60; p <0.05), lean mass (R0.72; p <0.05), and active cell mass (R0.59; p <0.05). The lipid profile in the I group of patients was significantly better before and at the end of the study. Long-term effects have not been investigated due to the short duration of the study.Conclusion:In patients with OA, a high frequency of concomitant diseases of the cardiovascular system, lipid metabolism disorders was found. Non-drug therapy has a positive effect on the lipid profile and the level of transaminases. The decrease in body weight due to loss of fat mass reliably correlates with the level of TG. Timely use of statins contributes to the normalization of the lipid profile, reduces the risk of cardiovascular disease in patients with OA. It is necessary to study lipid profile disorders in patients with OA with recommendations for lifestyle modification (diet, physical activity), and if necessary, prescribe lipid-correcting therapy.References:[1]E.

ABSTRACTThere is some evidence supporting the beneficial effects of a Paleolithic diet (PD) on cardiovascular disease (CVD) risk factors. This diet advises consuming lean meat, fish, vegetables, fruits, and nuts and avoiding intake of grains, dairy products, processed foods, and added sugar and salt. This study was performed to assess the effects of a PD on CVD risk factors including anthropometric indexes, lipid profile, blood pressure, and inflammatory markers using data from randomized controlled trials. A comprehensive search was performed in the PubMed, Scopus, ISI Web of Science, and Google Scholar databases up to August 2018. A meta-analysis was performed using a random-effects model to estimate the pooled effect size. Meta-analysis of 8 eligible studies revealed that a PD significantly reduced body weight [weighted mean difference (WMD) = −1.68 kg; 95% CI: −2.86, −0.49 kg], waist circumference (WMD = −2.72 cm; 95% CI: −4.04, −1.40 cm), BMI (in kg/m2) (WMD = −1.54; 95% CI: −2.22, −0.87), body fat percentage (WMD = −1.31%; 95% CI: −2.06%, −0.57%), systolic (WMD = −4.75 mm Hg; 95% CI: −7.54, −1.96 mm Hg) and diastolic (WMD = −3.23 mm Hg; 95% CI: −4.77, −1.69 mm Hg) blood pressure, and circulating concentrations of total cholesterol (WMD = −0.23 mmol/L; 95% CI: −0.42, −0.04 mmol/L), triglycerides (WMD = −0.30 mmol/L; 95% CI: −0.55, −0.06 mmol/L), LDL cholesterol (WMD = −0.13 mmol/L; 95% CI: −0.26, −0.01 mmol/L), and C-reactive protein (CRP) (WMD = −0.48 mg/L; 95% CI: −0.79, −0.16 mg/L) and also significantly increased HDL cholesterol (WMD = 0.06 mmol/L; 95% CI: 0.01, 0.11 mmol/L). However, sensitivity analysis revealed that the overall effects of a PD on lipid profile, systolic blood pressure, and circulating CRP concentrations were sensitive to removing some studies and to the correlation coefficients, hence the results must be interpreted with caution. Although the present meta-analysis revealed that a PD has favorable effects on CVD risk factors, the evidence is not conclusive and more well-designed trials are still needed.

ABSTRACT Background Paraoxonase-1 (PON-1) is a high-density lipoprotein (HDL)-associated enzyme with antioxidative properties, which may protect against the development of cardiovascular disease. Alcohol consumption increases HDL cholesterol, but the extent to which alcohol consumption gives rise to higher serum PON-1 activity is uncertain. Objective In a population-based study, we determined the relation of serum PON-1 activity with alcohol consumption when taking account of HDL cholesterol and apolipoprotein A-I (apoA-I), its major apolipoprotein. Design A cross-sectional study was performed in 8224 participants of the Prevention of Renal and Vascular End-Stage Disease (PREVEND) cohort. Alcohol consumption was categorized as 1) no/rarely (25.3%); 2) 0.1–10 g/d (49.3%); 3) 10–30 g/d (20.1%); and 4) >30 g/d (5.2%) with 1 drink equivalent to 10 g alcohol. Serum PON-1 activity was measured as its arylesterase activity (phenyl acetate as substrate). Results Median serum PON-1 activity was 50.8, 53.1, 54.4, and 55.7 U/L in the 4 categories of alcohol consumption, respectively (P < 0.001). Its increase paralleled the increments in HDL cholesterol and apoA-I. Notably, there was no further increase in PON-1 activity, HDL cholesterol, and apoA-I when alcohol consumption was increased from 10–30 g/d to >30 g/d. Multivariable linear regression analysis demonstrated that PON-1 activity was related to alcohol consumption independently from clinical covariates, high sensitivity C-reactive protein, and lipid concentrations, including HDL cholesterol (P < 0.001 for each category of alcohol consumption with no alcohol consumption as the reference category). Notably, as inferred from standardized β-coefficients, there was no difference in PON-1 activity between 10–30 g alcohol/d and >30 g alcohol/d. Conclusions Alcohol consumption is associated with an increase in serum PON-1 activity, but its effect seems to reach a plateau with alcohol consumption of 10–30 g/d.

Introduction: The increased prevalence of overweight, obesity, and metabolic syndrome has revealed that liver enzymes have a potential role as determinants of metabolic conditions such as, hyperlipidemia, and Cardiovascular Disease (CVD). Aim: The study aimed to investigate the correlation between liver enzymes with anthropometric indices of obesity and lipid profile in different obese phenotypes at a tertiary care. Materials and Methods: The present observational study was conducted on a total of 180 obese participants of either gender in the age group 18-59 years from December 2018 to May 2019. These were further divided into two phenotypic groups viz., Metabolically Healthy Obese (MHO group; n=90) and Metabolically Unhealthy Obese (MUHO group; n=90) according to NCEP ATP III criteria.Traditional cardiovascular risk factors were evaluated in the study participants through anthropometric viz., Body Mass Index (BMI), Waist Circumference (WC), Hip Circumference (HC), waist–hip ratio (WHR), blood pressure and biochemical investigations i.e., serum glucose, lipid profile and liver enzymes. Data was analysed by using Microsoft excel software. Results: Among 180 obese participants, 76 were males and 104 females with mean age 40.42±10.84 years. In MUHO phenotype, Gamma Glutamyl Transferase (GGT) showed a strong positive correlation with BMI (r=0.413, p=0.00001), lipid parameters viz., LDL-C (r=0.3785, p=0.0001), TC (r=0.2953, p=0.0023), TG (r=0.2623, p=0.006) and negative correlation with HDL-C (-r=0.3167, p=0.001). No significant correlation was found in MHO phenotype between liver enzymes, BMI and lipid profile parameters. Conclusion: The results of this study indicated that GGT shows a strong positive correlation with traditional risk factors in MUHO participants. Thus, raised GGT may be considered as a risk marker of CVD in MUHO phenotype.
