BACKGROUND: Obesity has a central role in the metabolic syndrome, which raises the risk for atherosclerotic cardiovascular disease (ASVCD). Apo B-48 and Apo B-100 are the necessary structural proteins required for the assembly and secretion of chylomicron and VLDL which have role in atherogenesis. The key initiating process in atherogenesis is the subendothelial retention of apolipoprotein B-containing lipoproteins. Oxidation of LDL is a hallmark of atherosclerosis development. The aim of this study was to asses the association between Apo B-48 and Apo B-100 with Oxidized-LDL as marker of atherosclerosis risk in central obesity. We hope that the result of this study can help to make a new strategy for the prevention and treatment of vascular disease.RESULTS: There were 68 patients aged 39.6±7.3 years, Apo B-48 concentration was 7.47±5.36 μg/mL, Apo B-100 was 117.26±25.74 mg/dL, and ox-LDL was 137.05±18.88 U/L. This study showed a significant correlation between Apo B-100 and ox-LDL (r=0.608, p<0.05) and correlation between Apo B-48 and ox-LDL (r=0.171, p<0.05). The levels of Apo B-100 were significantly different between obese with Mets and obese without Mets individuals (p<0.05).CONCLUSIONS: This study suggested that Apo B-100 concentration increase in obese in Mets as compared with obese without Mets. Apo B-48 and Apo B-100 were correlated with Oxidized LDL, but correlation between Apo B-100 and ox-LDL more significant that Apo B-48and ox-LDL.KEYWORDS: obesity, atherogenesis, Apo B-48, Apo B-100, ox-LDL

Patients with Type II diabetes mellitus or the metabolic syndrome have unique dyslipidemia characterized by hypertriglyceridemia; elevated blood levels of apolipoprotein B; small, dense low-density lipoprotein (LDL) cholesterol; and low levels of high-density lipoprotein (HDL) cholesterol. Treatment of dyslipidemia associated with these disorders should focus on correcting the abnormal lipoprotein levels as well as LDL and HDL heterogeneity. Statins and fibrates are useful for treating elevated LDL in patients with and without diabetes or the metabolic syndrome. There are few researches on Apolipoprotein A and Apolipoprotein B, Lipoprotein (a) in India, in comparison to foreign countries. So this study is aimed to evaluate Apo lipoproteins (Apo A1 & Apo B) and Lipoprotein (a) levels along with Lipid profile in Type II Diabetes Mellitus and in patients with Metabolic Syndrome which can be correlated with the risk of cardiovascular disease. Conclusion: Apo lipoprotein A1, Apolipoprotein B and Lipoprotein (a) can be important marker for the risk developing of heart disease. Statistical relationships between LDL and HDL and their respective Apo lipoproteins, Apo B and Apo A-1, in diabetic and metabolic syndrome can be established. Keywords:  Lipid profile, Type II Diabetes Mellitus, Apo lipoproteins (Apo A & Apo B), Lipoprotein (a) and Metabolic Syndrome.

Obesity and metabolic syndrome (MetS) are public health problems and are increasing globally. We assessed the differences in lipid profiles through lipid testing, thrombotic and inflammatory parameters, and oxidative stress indexes between overweight and obese patients with MetS in a Turkish adult population. We included 100 obese (body mass index [BMI] >30 kg/m2) patients with MetS (66 women, 34 men, mean age 54.0 ± 10.1 years) and 15 overweight (BMI 25-30 kg/m2) individuals (11 women, 4 men, mean age 50.2 ± 14.5 years) as controls. The group with MetS had significantly higher levels of glycaemia, uric acid, high-sensitivity C-reactive protein, homocysteine, fibrinogen, total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, small dense LDL, oxidized LDL, apolipoprotein B (Apo B), lipoprotein (a), small and intermediate high-density lipoprotein (HDL) particles, oxidative stress index, and significantly lower levels of HDL-cholesterol (HDL-C), Apo A, and large HDL particles. In conclusion, obesity with MetS increase atherogenic dyslipidemia and thrombotic, inflammatory and oxidative stress biomarkers. Furthermore, obesity with MetS decreases protective mechanisms of atherosclerosis. We should at least try to prevent overweight individuals from becoming obese with MetS.

Pigment epithelium-derived factor (PEDF) is a glycoprotein that belongs to the superfamily of serine protease inhibitors, serpins. It was first identified as a neuronal differentiating factor secreted by human retinal pigment epithelial cells, and then found to be the most potent inhibitor of pathological angiogenesis in mammalian eyes. Recently, PEDF has been shown not only to suppress oxidative stress and inflammatory reactions in vascular wall cells, T cells and macrophages, and adipocytes, but also to exert antithrombotic and anti-fibrotic properties, thereby protecting against the development and progression of various cardiometabolic diseases and related complications. Furthermore, accumulating evidence has suggested that circulating PEDF levels may be a biomarker of severity and prognosis of these devastating disorders. Number of subjects with visceral obesity and insulin resistance is increasing, and the metabolic syndrome and its related complications, such as diabetes, nonalcoholic fatty liver disease/non-alcoholic steatohepatits, and atherosclerotic cardiovascular disease are a growing health challenge. Therefore, in this study, we review the pathophysiological role of PEDF in obesity and metabolic disorders, cardiovascular disease, diabetic eye and kidney complications, liver diseases, and reproductive system disorders, and discuss the potential clinical utility of modulating the expression and actions of PEDF for preventing these cardiometabolic disorders. We also refer to the clinical value of PEDF as a biomarker in cardiometabolic complications.

The metabolic syndrome (MetS) comprises individual components including central obesity, insulin resistance, dyslipidaemia and hypertension and it is associated with an increased risk of cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). The menopause per se increases the incidence of MetS in aging women. The effect(s) of menopause on individual components of MetS include: i) increasing central obesity with changes in the fat tissue distribution, ii) potential increase in insulin resistance, iii) changes in serum lipid concentrations, which seem to be associated with increasing weight rather than menopause itself, and, iv) an association between menopause and hypertension, although available data are inconclusive. With regard to the consequences of MetS during menopause, there is no consistent data supporting a causal relationship between menopause and CVD. However, concomitant MetS during menopause appears to increase the risk of CVD. Furthermore, despite the data supporting the association between early menopause and increased risk of T2DM, the association between natural menopause itself and risk of T2DM is not evident. However, the presence and the severity of MetS appears to be associated with an increased risk of T2DM. Although the mechanism is not clear, surgical menopause is strongly linked with a higher incidence of MetS. Interestingly, women with polycystic ovary syndrome (PCOS) have an increased risk of MetS during their reproductive years; however, with menopausal transition, the risk of MetS becomes similar to that of non-PCOS women.

Abstract Introduction Ataxia-Telangiectasia (A-T) is a multi-system disorder that may be associated with endocrine changes, oxidative stress in addition to inflammation. Studies suggest that selenium is a trace element related to protection against damage caused by oxidative stress. Objective To describe the plasma levels of selenium and erythrocyte glutathione peroxidase activity in A-T patients and to relate them to oxidative stress and lipid status biomarkers. Methods This is a cross-sectional and controlled study evaluating 22 A-T patients (age median, 12.2 years old) matched by gender and age with 18 healthy controls. We evaluated: nutritional status, food intake, plasma selenium levels, erythrocyte glutathione peroxidase activity, lipid status, inflammation and oxidative stress biomarkers. Results Adequate levels of selenium were observed in 24/36 (66.7%) in this evaluated population. There was no statistically significant difference between the groups in selenium levels [47.6 μg/L (43.2–57.0) vs 54.6 (45.2–62.6) μg/dL, p = 0.242]. Nine of A-T patients (41%) had selenium levels below the reference value. The A-T group presented higher levels of LDL-c, non-HDL-c, oxidized LDL, Apo B, Apo-B/Apo-A-I1, LDL-c/HDL-c ratio, malondialdehyde [3.8 µg/L vs 2.8 µg/L, p = 0.029] and lower Apo-A-I1/HDL-c and glutathione peroxidase activity [7300 U/L vs 8686 U/L, p = 0.005]. Selenium levels were influenced, in both groups, independently, by the concentrations of oxidized LDL, malonaldehyde and non-HDL-c. The oxidized LDL (AUC = 0.849) and ALT (AUC = 0.854) were the variables that showed the greatest discriminatory power between groups. Conclusion In conclusion, we observed the presence of selenium below the reference value in nearly 40% and low GPx activity in A-T patients. There was a significant, inverse and independent association between selenium concentrations and oxidative stress biomarkers. Those data reinforce the importance of assessing the nutritional status of selenium in those patients.

Abstract Background Familial hypertriglyceridemia (FHTG) is a partially characterized primary dyslipidemia which is frequently confused with other forms hypertriglyceridemia. The aim of this work is to search for specific features that can help physicians recognize this disease. Methods This study included 84 FHTG cases, 728 subjects with common mild-to-moderate hypertriglyceridemia (CHTG) and 609 normotriglyceridemic controls. All subjects underwent genetic, clinical and biochemical assessments. A set of 53 single nucleotide polymorphisms (SNPs) previously associated with triglycerides levels, as well as 37 rare variants within the five main genes associated with hypertriglyceridemia (i.e. LPL, APOC2, APOA5, LMF1 and GPIHBP1) were analyzed. A panel of endocrine regulatory proteins associated with triglycerides homeostasis were compared between the FHTG and CHTG groups. Results Apolipoprotein B, fibroblast growth factor 21(FGF-21), angiopoietin-like proteins 3 (ANGPTL3) and apolipoprotein A-II concentrations, were independent components of a model to detect FHTG compared with CHTG (AUC 0.948, 95%CI 0.901–0.970, 98.5% sensitivity, 92.2% specificity, P < 0.001). The polygenic set of SNPs, accounted for 1.78% of the variance in triglyceride levels in FHTG and 6.73% in CHTG. Conclusions The clinical and genetic differences observed between FHTG and CHTG supports the notion that FHTG is a unique entity, distinguishable from other causes of hypertriglyceridemia by the higher concentrations of insulin, FGF-21, ANGPTL3, apo A-II and lower levels of apo B. We propose the inclusion of these parameters as useful markers for differentiating FHTG from other causes of hypertriglyceridemia.

Apolipoprotein B-100 (apo B-100) is the protein ligand in low-density lipoproteins that binds to a specific cell-surface receptor. Its molecular mass has been a subject of controversy. We have determined the molecular mass of the protein by a chemical approach. After complete CNBr cleavage, the C-terminal fragment of apo B-100 was purified by reverse-phase h.p.l.c. Amino acid N- and C-terminal analyses confirm that this peptide represents the C-terminal peptide as deduced from the DNA sequence of a human apo B-100 cDNA clone. A chemically synthesized peptide was used to determine the recovery of the peptide (74.72%). On the basis of these data, the molecular mass of apo B-100 was determined to be 496.82 +/- 24.84 kDa.
