Background In the 21st century, cardiovascular diseases will continue to dominate the disease spectrum and death statistics in both the industrialized and developing worlds. Coronary artery disease (CAD) is the foremost cause of cardiovascular disease related deaths worldwide, with >4.5 million deaths taking place in the developing world. Augmented serum uric acid levels are recurrently come across with hyperlipidemia, atherosclerosis, obesity, glucose intolerance, renal disease, and hypertension which all play a fundamental role in the pathogenesis of coronary artery disease.  Materials and methods It was a hospital based case control study carried out in the Department of Biochemistry of Manipal Teaching Hospital, Pokhara, Nepal between 1st January 2010 and 31st December 2010. The variables collected were age, gender, serum uric acid, total cholesterol, low density lipoproteins, triglycerides, high density lipoproteins and very low density lipoproteins. Approval for the study was obtained from the institutional research ethical committee. Results There was insignificant difference for age between groups. In cases of  hyperuricemia, there was marked increase in levels of serum uric acid (8.043± 0.43 mg/dl) when compared to controls (4.28 ± 0.66 mg/dl. In patients suffering from coronary artery disease with hyperuricemia, there was marked increased in levels of serum uric acid(8.222 ± 0.39 mg/dl)  found to be statistically significant when compared to controls (4.285 ±0.66 mg/dl) and values were quite similar to hyperuricemic patients (8.043 ± 0.43 mg/dl).Further, in patients suffering from coronary artery disease with hyperuricemia, there was marked increased in mean values of serum total cholesterol (257.56 ± 22.65 mg/dl) ) when compared to controls (173.22 ± 32.63mg/dl). Conclusion Hypercholesterolemia due to hyperuricemia is most common modifiable factor for coronary artery disease. Allopurinol and newer urate-lowering agents restores endothelial function in coronary artery disease patients. The ability of physicians to pharmacologically manage serum urate levels, a better understanding of the interaction between hyperuricemia, gout and vascular disease may be critical for the reduction of morbidity and mortality in high-risk coronary artery disease patients.Key words: Hyperuricemia; Coronary artery disease; Nepal DOI: http://dx.doi.org/10.3126/nje.v1i3.5571 Nepal Journal of Epidemiology 2011;1(3) 81-85

Selective Uptake

Selective uptake of cholesteryl esters (CE) from lipoproteins by cells has been extensively studied with high density lipoproteins (HDL). It is only recently that such a mechanism has been attributed to intermediate and low density lipoproteins (IDL and LDL). Here, we compare the association of proteins and CE from very low density lipoproteins (VLDL), IDL, LDL and HDL3 to HepG2 cells. These lipoproteins were either labelled in proteins with 125I or in CE with 3H-cholesteryl oleate. We show that, at any lipoprotein concentration, protein association to the cells is significantly smaller for IDL, LDL, and HDL3 than CE association, but not for VLDL. At a concentration of 20 µg lipoprotein/mL, these associations reveal CE-selective uptake in the order of 2-, 4-, and 11-fold for IDL, LDL, and HDL3, respectively. These studies reveal that LDL and HDL3 are good selective donors of CE to HepG2 cells, while IDL is a poor donor and VLDL is not a donor. A significant inverse correlation (r2 = 0.973) was found between the total lipid/protein ratios of the four classes of lipoproteins and the extent of CE-selective uptake by HepG2 cells. The fate of 3H-CE of the two best CE donors (LDL and HDL3) was followed in HepG2 cells after 3 h of incubation. Cells were shown to hydrolyze approximately 25% of the 3H-CE of both lipoproteins. However, when the cells were treated with 100 µM of chloroquine, a lysosomotropic agent, 85 and 40% of 3H-CE hydrolysis was lost for LDL and HDL3, respectively. The fate of LDL and HDL3-CE in HepG2 cells deficient in LDL-receptor was found to be the same, indicating that the portion of CE hydrolysis sensitive to chloroquine is not significantly linked to LDL-receptor activity. Thus, in HepG2 cells, the magnitude of CE-selective uptake is inversely correlated with the total lipid/protein ratios of the lipoproteins and CE-selective uptake from the two best CE donors (LDL and HDL3) appears to follow different pathways.Key words: lipoprotein, receptor, HepG2 cell, selective uptake, lipid, cholesterol, binding.

Atherosclerotic Changes

Atherosclerosis is one of the most common disorders among the elderly. Depression may be associated with the development of atherosclerosis. Thus, the aim of this study is to evaluate and compare the effects of escitalopram (a selective serotonin reuptake inhibitor) with atorvastatin (a well known antihyperlipidemic drug) on high fat diet induced atherosclerosis in rats. The results of this study showed that the administration of either escitalopram or atorvastatin for 6 weeks was associated with a significant decrease in serum levels of total cholesterol, triglycerides, low density lipoproteins, very low density lipoproteins, and serum malondialdehyde, and a significant increase in high density lipoproteins when compared with the atherosclerosis model group. Histopathological examination of the aortas from the test rats revealed significant regression of atherosclerotic changes, together with a significant decrease in vascular cell adhesion molecule-1 (VCAM-1) expression in the media of both the escitalopram group and the atorvastatin group when compared with the atherosclerosis model group. This study has shown that escitalopram reduced atherosclerotic changes, thus its use as an antidepressant in elderly patients should be considered.

AbstractObjectivesTo evaluate the first trimester maternal biomarkers for early pregnancy prediction of gestational diabetes mellitus (GDM).MethodsThe study was a case-control study of healthy women with singleton pregnancies at the first trimester carried out at the Obstetrics and Gynecology Unit, Clinica Davila, Santiago, Chile. After obtaining informed consent, peripheral blood samples of pregnant women under 14 weeks of gestation were collected. At 24–28 weeks of pregnancy, women were classified as GDM (n=16) or controls (n=80) based on the results of a 75-g oral glucose tolerance test (OGTT). In all women, we measured concentrations of fasting blood glucose, insulin, glycated hemoglobin, uric acid, cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (GGT), alkaline phosphatase (AP), sex hormone-binding globulin (SHBG), adiponectin, tissue plasminogen activator (t-PA), leptin and placental growth factor (PGF).ResultsThe GDM group displayed an increased median concentration of cholesterol (P=0.04), triglycerides (P=0.003), insulin (P=0.003), t-PA (P=0.0088) and homeostatic model assessment (HOMA) (P=0.003) and an increased mean concentration of LDL (P=0.009) when compared to the control group. The receiver operating characteristic (ROC) curve for significant variables achieved an area under the curve (AUC) of 0.870, a sensitivity of 81.4% and a specificity of 80.0%. The OGTT was positive for GDM according to the IADPSG (International Diabetes in Pregnancy Study Group) criteria.ConclusionWomen who subsequently developed GDM showed higher levels of blood-borne biomarkers during the first trimester, compared to women who did not develop GDM. These data warrant validation in a larger cohort.

Serum lipoproteins may enter the airways and appear in sputum (chyloptysis) when the lymphatic circulation is impaired by inflammation, neoplasia, or an abnormal proliferation of smooth muscle cells. While analyzing the bronchoalveolar lavage fluid of a patient with chyloptysis, we noticed that surfactant could not be separated from contaminating serum lipoproteins and speculated that lipoproteins might interact with surfactant components. To clarify this point we immobilized surfactant protein (SP) A on microtiter wells and incubated it with 125I-labeled very low density lipoproteins (VLDLs), low-density lipoproteins, and high-density lipoproteins. We found that SP-A binds lipoproteins. Studying in greater detail the interaction of SP-A with VLDLs, we found that the binding is time and concentration dependent; is inhibited by unlabeled lipoproteins, phospholipids, and antibodies to SP-A; is increased by Ca2+; and is unaffected by methyl α-d-mannopyranoside. Whole surfactant is a potent inhibitor of binding. Furthermore, we found that SP-A increases the degradation of VLDLs by alveolar macrophages and favors the association of VLDLs with alveolar surfactant. We conclude that SP-A influences the disposal of serum lipoproteins entering the airways and speculate that binding to alveolar surfactant might represent an important step in the interaction between exogenous substances and the lung.

Abstract Background and Aim Psoriasis have a direct impact on development of cardiovascular risk factors leading to atherosclerosis and metabolic abnormalities. In order to prevent the complications, early and prompt identification of factors through various parameters help in primary and secondary prevention of cardiovascular diseases (CVDs) among these psoriatic patients. Therefore the aim of this study is to determine the prevalence of various determinants for cardiovascular diseases among cases and controls. Methods A hospital based case control study at a tertiary care hospital included women from the out patient department, aged above 18 years who were known cases of psoriasis. 114 patients were recruited with 1:1 ratio between cases and controls. All patients were evaluated using semi structured interview schedule with socio demographic variables, duration of disease, family history, and usage of drugs. Severity of disease was assessed through the psoriasis area severity index (PASI). Body surface area (BSA), body mass index (BMI), waist circumference and blood pressure measurement were done using standard methods. Lipid profile, high sensitivity C-Reactive protein (HsCRP) and blood sugar through calibrated analyzers having quality control. Carotid intima media thickness (CIMT) was assessed by using carotid Doppler technique to measure atherosclerosis. Results One hundred fourteen patients, means 57 pairs of cases and controls were analyzed in this study. Significant determinants among cases were raised such as waist circumference (p = 0.025), diastolic blood pressure (p = 0.0001), low density lipoprotein (p = 0.002) and fasting blood glucose (p = 0.004) when compared to controls. HsCRP and CIMT were also raised among cases but only CIMT was statistically significant when compared to controls (p = 0.0001). We also found raised determinants among psoriatic arthritis patients compared to psoriasis. Conclusion Psoriasis patients had high waist circumference, diastolic blood pressure, low density lipoprotein, fasting blood glucose, and CIMT when compared to controls. Early identification of these determinants make them amenable for prevention.
