Abstract Background: Triglycerides (TG)/high-density lipoprotein (HDL) cholesterol ratio is a marker of small/dense low-density lipoprotein particles, which are closely associated with various metabolic and vascular diseases. However, the role of TG/HDL cholesterol ratio in cerebrovascular diseases has not been well studied. In this study, we evaluated the relationship between TG/HDL cholesterol ratio and the presence of silent brain infarct (SBI) in a neurologically healthy population. Methods: We retrospectively evaluated consecutive participants in health check-ups between January 2006 and December 2013. SBI was defined as an asymptomatic, well-defined lesion with a diameter of ≥ 3 mm on T1- or T2-weighted images. TG/HDL cholesterol ratio was calculated after dividing absolute TG levels by absolute HDL cholesterol levels. Results: Of 3,172 healthy participants, 263 (8.3%) had SBI lesions. In multivariate analysis, TG/HDL cholesterol ratio was independently associated with SBI (adjusted odds ratio [aOR] = 1.17, 95% confidence interval [CI] = 1.04 to 1.32, P = 0.012). This association was prominent in males (aOR = 1.20, 95% CI = 1.04 to 1.40, P = 0.015), but not in females. Other lipid parameters, such as HDL cholesterol (aOR = 0.87, 95% CI = 0.75 to 1.00, P = 0.042), TG (aOR = 1.15, 95% CI = 1.02 to 1.31, P = 0.02), and total cholesterol/TG ratio (aOR = 0.86, 95% CI = 0.75 to 1.00, P = 0.043) also showed significant relationships with SBI, when they were respectively adjusted for confounders. In the analyses of the relationships between lipid parameters and SBI lesion burden, TG/HDL cholesterol ratio was positively correlated, and total cholesterol/TG ratio was negatively correlated with SBI lesion burden, in dose-response manners (P for trend = 0.015 and 0.002, respectively). Conclusions: The TG/HDL cholesterol ratio was positively associated with the prevalence of SBI in a neurologically healthy population.

Statin side effects are not a rare occurrence, in particular dyspeptic disorders, insomnia, headache, skin erythema, rash are often noted. All of this determines scientists to find new effective and low-toxic hypolipidemic agents. Various natural and synthetic xanthine derivatives have been recognized as therapeutically potential compounds and reported to control various diseases. Therefore, the study of new xanthine derivatives and their hypolipidemic effects, which would have a significant therapeutic effect with minimal side effects, is relevant. The aim of the study was to examine the effect of 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkanic acid derivatives on lipidogram parameters in experimental laboratory rats. Materials and methods. The objects of the study were 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkanic acid derivatives. The experiments were performed in white laboratory Wistar rats weighing 180–220 g. Experimental modeling of hyperlipidemia – tween model: intraperitoneal administration of tween-80 at a dose of 200 mg/100 g body weight. The test compounds were administered orally, simultaneously with tween, at a dose of 1/10 of LD50 (previously calculated by Prozorovsky express method) for 6 days. The following indicators of lipidogram were determined: total cholesterol (TC), high-density lipoprotein cholesterol (HDL cholesterol), low-density lipoprotein cholesterol (LDL cholesterol), triglycerides (TG) and atherogenic index of plasma: TC – HDL cholesterol / HDL cholesterol. The experiments were carried out with respect to Bioethical rules and norms. Results. The studies have shown data on the hypolipidemic activity of 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkane acid derivatives. According to the conditional efficiency index Ʃ, which included the overall percentage of the following indicators – total cholesterol, low-density lipoprotein cholesterol and triglycerides, the leading compounds were 2439 (87.47 %), 6047 (82.30 %). The reference drug atorvastatin had a value of 82.98 %. Conclusions. The major compound was 2439 identified among all compared to the control group. The prospect of further research is a more detailed study on the ability of xanthine derivatives to exhibit hypolipidemic effects and to influence oxidative stress in various hyperlipidemic models.

Objective: is to assess the dyslipidemia control and demographic differences in lipid patterns among dyslipidemic cardiac patients. Method: data based a retrospective analysis of 504 persons (age mean 58.16 ± 11.119 years) was conducted in Malaysia which estimated the lipid abnormalities in statin-treated patients. Demographic data including age, race, alcoholic and smoking status were collected. Lipid profiles including triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured. Results: a desirable level of (TC) and (TG) were 62.2% and 54.4% respectively, optimal level of (LDL-C) was 66.5% and the normal level of (HDL-C) was 54.2%. Risk factor analysis of dyslipidemia was done with a primary focus on the possible impact of statin type, gender, race and dyslipidemia type. Atorvastatin was significantly more effective for primary dyslipidemia than simvastatin and lovastatin in HDL cholesterol ( p < 0.002), while in LDL cholesterol (p = 0.001) and total cholesterol (p < 0.03) simvastatin was significantly found more effective for primary dyslipidemia. A significant correlation emerged between gender and statin type in HDL cholesterol (p < 0.02) and total cholesterol TC (p < 0.001), atorvastatin is found more effective to be used by males than females. A correlation was also significant between gender and dyslipidemia type in HDL cholesterol (p < 0.01). Results for triglyceride reported a significant relationship between age, race and statin type (p < 0.001), atorvastatin was found to be more effective among Chinese while lovastatin was more effective among Indians. Finally 18.2% abnormality of HDL was explained by interactions of risk factors: first statin type and dyslipidemia type, second for gender and dyslipidemia type and the third was gender and statin type. Conclusions: more than 50% of cardiac outpatients were in an acceptable range of lipid profile evaluation. This could support the need for increasing attention to basic monitoring of cardiovascular risk factors in these dyslipidemic patients particularly in Asian population.

Abstract Context The incidence of preeclampsia (PE) is increased in women with diabetes (∼20% vs ∼5% in the general population), and first trimester lipoprotein profiles are predictive. Haptoglobin (Hp), a protein with functional genetic polymorphisms, has antioxidant, anti-inflammatory, and angiogenic effects. Among people with diabetes, the Hp 2-2 phenotype is associated with cardiorenal disease. Objective To investigate whether Hp phenotype is associated with PE in type 1 diabetes mellitus (T1DM) and/or modulates lipoprotein-associated risks. Design and Setting Multicenter prospective study of T1DM pregnancy. Patients Pregnant women with T1DM (normal albuminuria, normotensive at enrolment, n = 47) studied at three visits, all preceding PE onset: 12.3 ± 1.9, 21.8 ± 1.5, and 31.5 ± 1.6 weeks’ gestation (mean ± SD). Main Outcome Measures Hp phenotype and lipoprotein profiles in women with (n = 23) vs without (n = 24) subsequent PE. Results Hp phenotype did not predict PE, but lipoprotein associations with subsequent PE were confined to women with Hp 2-2, in whom the following associations with PE were observed: increased low-density lipoprotein (LDL) cholesterol, LDL particle concentration, apolipoprotein B (APOB), triacylglycerol/high-density lipoprotein (HDL) cholesterol ratio, and APOB/apolipoprotein AI (APOA1) ratio; decreased HDL cholesterol, APOA1, large HDL particle concentration, and peripheral lipoprotein lipolysis (all P < 0.05). In women with one or two Hp-1 alleles, no such associations were observed. Conclusions In women with T1DM, although Hp phenotype did not predict PE risk, lipoprotein-related risks for PE were limited to those with the Hp 2-2 phenotype. Hp phenotype may modulate PE risk in diabetes.

Abstract We determined the physiological variability of total cholesterol, high- (HDL) and low-density lipoprotein (LDL) cholesterol, triglycerides, and apolipoproteins A-I and B in fasting blood samples from patients referred to the Johns Hopkins Lipid Referral Clinic. Samples were taken on each of three occasions during baseline evaluation visits before the patients were treated. The median physiological coefficients of variation (CVp) were as follows: total cholesterol, 5.0%; triglycerides, 17.8%; HDL cholesterol, 7.1%; LDL cholesterol, calculated from the previous three measurements, 7.8%; and apolipoproteins A-I and B, 7.1% and 6.4%, respectively. There were no significant differences in CVp between children (less than or equal to 18 years) and adults (greater than 18 years) for any of the measurements. On the basis of our findings, single measurements in serial samples taken on three occasions suffice to establish the patients' usual values with the following precisions (+/- 1 CV): total cholesterol, +/- 4%; triglycerides, +/- 11%; HDL cholesterol, +/- 8%; LDL cholesterol, +/- 6%; and apolipoproteins A-I and B, +/- 7%.

Recent studies have demonstrated an association between low weight at birth and an atherogenic lipid profile in later life. To examine the influences of intrauterine and genetic factors, we investigated 53 dizygotic and 61 monozygotic adolescent twin pairs. Regression analysis demonstrated that low birth weight was associated with high levels of total cholesterol, low-density lipoprotein (LDL) cholesterol and apolipoprotein B (−0.17 mmol/liter per kg, P = 0.07; −0.18 mmol/liter per kg, P = 0.04; and− 0.07 g/liter per kg, P = 0.02, respectively) and with low levels of high-density lipoprotein (HDL) cholesterol (+0.04 mmol/liter per kg, P = 0.1), after adjustment for age, sex, and body mass index. Intrapair differences in birth weight were significantly associated with differences in total cholesterol, LDL cholesterol, and apolipoprotein B in dizygotic twins after adjustment for differences in current body mass index (−0.49 mmol/liter per kg, P = 0.02; −0.51 mmol/liter per kg, P = 0.01; and −0.10 g/liter per kg, P = 0.04, respectively), demonstrating that the larger the difference in birth weight, the higher these risk factors in the twin with the lower birth weight, compared with the cotwin with the higher birth weight. In monozygotic twins, however, the associations between intrapair differences in birth weight and differences in total cholesterol, LDL cholesterol, and apolipoprotein B were in the opposite direction (+0.32 mmol/liter per kg, P = 0.03; +0.23 mmol/liter per kg, P = 0.08; and +0.06 g/liter per kg, P = 0.04, respectively). The association between intrapair differences in birth weight and differences in HDL cholesterol was not significant in dizygotic twins (+0.04 mmol/liter per kg, P = 0.6) and of borderline significance in monozygotic twins (+0.11 mmol/liter per kg, P = 0.05). These data suggest that genetic factors account for the association of low birth weight with high levels of total cholesterol, LDL cholesterol, and apolipoprotein B, whereas intrauterine factors possibly play a role in the association between birth weight and HDL cholesterol.

Chronic renal failure (CRF) is associated with increased risk of arteriosclerotic cardiovascular disease and profound alteration of plasma lipid profile. Uremic dyslipidemia is marked by increased plasma concentration of ApoB-containing lipoproteins and impaired high-density lipoprotein (HDL)-mediated reverse cholesterol transport. These abnormalities are, in part, due to acquired LCAT deficiency and upregulation of hepatic acyl-CoA:cholesterol acyltransferase (ACAT). ACAT catalyzes intracellular esterification of cholesterol, thereby promoting hepatic production of ApoB-containing lipoproteins and constraining HDL-mediated cholesterol uptake in the peripheral tissues. In view of the above considerations, we tested the hypothesis that pharmacological inhibition of ACAT may ameliorate CRF-induced dyslipidemia. 5/6 Nephrectomized rats were treated with either ACAT inhibitor IC-976 (30 mg·kg−1·day−1) or placebo for 6 wk. Sham-operated rats served as controls. Key cholesterol-regulating enzymes, plasma lipids, and creatinine clearance were measured. The untreated CRF rats exhibited increased plasma low-density lipoprotein (LDL) and very LDL (VLDL) cholesterol, unchanged plasma HDL cholesterol, elevated total cholesterol-to-HDL cholesterol ratio, reduced liver microsomal free cholesterol, and diminished creatinine clearance. This was accompanied by reduced plasma LCAT, increased hepatic ACAT-2 mRNA, ACAT-2 protein and ACAT activity, and unchanged hepatic HMG-CoA reductase and cholesterol 7α-hydroxylase. ACAT inhibitor raised plasma HDL cholesterol, lowered LDL and VLDL cholesterol, and normalized total cholesterol-to-HDL cholesterol ratio without changing total cholesterol concentration (hence, a shift from ApoB-containing lipoproteins to HDL). This was accompanied by normalizations of hepatic ACAT activity and plasma LCAT. In conclusion, inhibition of ACAT reversed LCAT deficiency and improved plasma HDL level in CRF rats. Future studies are needed to explore the efficacy of ACAT inhibition in humans with CRF.

Background: Coronary Heart Disease (CHD) is widely prevalent across the globe and significantly high level of Cholesterol in circulation is a single major risk factor associated with coronary heart disease. It is well established that cardiovascular disease is associated with hypertension and elevated blood levels of low-density lipoprotein (LDL), total cholesterol, and triglycerides. In disparity, a low level of high-density lipoprotein (HDL) is a risk factor for mortality from cardiovascular disease. Aim: The present study was conducted with the aim to assess the lipid profile in patients of Acute Coronary Syndrome (ACS) undergoing coronary angiography (CAG) in rural coastal population. Patients and Methods: The present study was done on 62 patients with Acute Coronary Syndrome (ACS) undergoing coronary angiography (CAG) Serum levels of total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides were examined in biochemical laboratory of the hospital. Coronary angiography was performed for the presence of lesions. Results: 43.5% of the patients (n=27) were elderly (age>60 years). Approximately 82% of the patients (n=51) aged more than 50 years. Males outnumbered females with a ratio of 2.4:1. 71% of the patients were males. Mean cholesterol levels were 177.86 mg/dl. Approx 3/4th of the patients (n=41) had cholesterol level <200 mg/Dl. Mean triglycerides levels in the patients were 158.29 mg/dl. Only 11 patients out of 62 CAD patients had abnormal triglycerides. Mean LDL level was 119.5 mg and Mean HDL level was 34.5 mg %. The high plasma concentration of low-density lipoprotein (LDL-C) in 30% and the low plasma concentration of high-density lipoprotein (HDL-C) n 33% of patients were important abnormal findings in our patients. Conclusion: Dyslipidemia as in form of very low levels of HDL cholesterol with comparatively high levels of LDL-c with near normal total Cholesterol and triglyceride levels associated with ACS in our rural costal region of Maharashtra.
