In Pregnancy

Cholesterol forms part of every cell in the human body, and also helps make and metabolize hormones, bile acids and vitamin D. Human plasma cholesterol levels are determined by production in the liver and by dietary intake. Lipoproteins carry cholesterol around the body, and facilitate it crossing the placenta. Cholesterol is carefully monitored in the non-pregnant adult population, where its association with atherosclerosis and cardiovascular disease is well understood. Although it is known that cholesterol rises in pregnancy, at present it is not routinely measured or treated. The effects of maternal high cholesterol on pregnancy and on fetal development are not yet fully understood. However, a growing body of evidence from animal and human studies suggests adverse consequences of high cholesterol levels in pregnancy.

Cholesterol is a waxy substance which is mainly made in the body. Cholesterol can provide benefits. However, having too much cholesterol in the blood can increase risk of cardiovascular disease. Prevention and treatment of cardiovascular disease can be done by taking synthetic drugs such as statin. Due to side effects of synthetic drugs, it is necessary to substitute synthetic drugs with herbal plant and some natural component in these plants. The important ones is garlic. Garlic contain organosulphur compounds such as diallyldisulphide (DADS), dipropyldisulphide (DPDS), diallytrisulphide (DATS) and dipropyltrisulphide (DPTS) which have anti artherogenic effects. Garlic also have active agent allicin, can reduce the levels of cholesterol. This research was conducted at the Experimental Animal Enclosure Installation, Center for Veterinary Farma Surabaya with 3 experimental groups. Animals used in this research were female mice 2 months old were feeding with high cholesterol feed such as fried offal of chicken twice a day as much 0,5 cc/ day every 3 days. On the 3rd day, the levels of cholesterol in each group was examined. On the 4th day, mice in group 3 were given 1cc of garlic juice. 1 hour later mice was examined blood cholesterol using Strip Test Easy Touch GCU. The results through T-paired test on SPSS stated that (p < 0,05), it means there is influence between the 3 treatment of mice. This results it can be concluded that the provision of garlic juice can reduced blood cholesterol levels in mice after fed with high cholesterol.

Background: Deficiency of vitamin D is quite prevalent among elderly population or postmenopausal women worldwide and may affect various function of the body. The status of its deficiency with their relation with other variables are not well explored in perimenopausal women.Methods: 100 perimenopausal women from the department of obstetrics and gynaecology were selected without having known risk of thyroid disorder and cardiovascular disease. The age group criteria for these women were 40 to 50 years. Thyroid profile including TSH, T3, and T4 were estimated by using enzyme linked immunesorbent assay. Serum levels of 25(OH) D3 was estimated by using spectrophotometric method. Lipid profile including TC, TG and HDL-C were estimated CHOD-POD method, GPO-PAP method, and CHOD-POD/Phosphotungustate method. LDL-C was calculated by friedewald formula.Results: There 58 women were presented with insufficient amount of vitamin D. They were characterised with increased BMI, elevated thyrotropin alongwith lower concentrations of T3 and T4. Increased levels of TC, TG and LDL-cholesterol alongwith lower concentration of HDL-C were also observed in women with vitamin d deficiency. Women having vitamin D deficiency were presented with overweight (OR-18.0, p-value=<0.001) and dyslipidemia (OR-12.13, p-value≤0.001). Vitamin D was negatively correlated with variable i.e. BMI, TSH, TC, TG and LDL-C. This negative association was significant (<0.001) while HDL-C and T4 were positively correlated with vitamin D levels in this study population.Conclusions: Vitamin D deficiency frequently occurs in middle aged perimenopausal women. Negative correlation of it with BMI, TSH and lipid variables may suggest the development of cardiovascular disease and hypothyroidism in coming years. Vitamin D supplements or vitamin D containing diet and regular exposure to sun is highly recommended to perimenopausal women.

Cholesterol homeostasis is maintained through concerted action of the SREBPs and LXRs. Here, we report that RNF145, a previously uncharacterized ER membrane ubiquitin ligase, participates in crosstalk between these critical signaling pathways. RNF145 expression is induced in response to LXR activation and high-cholesterol diet feeding. Transduction of RNF145 into mouse liver inhibits the expression of genes involved in cholesterol biosynthesis and reduces plasma cholesterol levels. Conversely, acute suppression of RNF145 via shRNA-mediated knockdown, or chronic inactivation of RNF145 by genetic deletion, potentiates the expression of cholesterol biosynthetic genes and increases cholesterol levels both in liver and plasma. Mechanistic studies show that RNF145 triggers ubiquitination of SCAP on lysine residues within a cytoplasmic loop essential for COPII binding, potentially inhibiting its transport to Golgi and subsequent processing of SREBP-2. These findings define an additional mechanism linking hepatic sterol levels to the reciprocal actions of the SREBP-2 and LXR pathways.

Injectable DMPA contraception can cause changes in lipoprotein metabolism. Changes in fat metabolism occur because of the hormonal influence of progesterone, causing disruption of the balance of lipid profiles in the body. The change in serum lipid profile (trgliseride, total cholesterol, HDL and LDL) in long-term use of DMPA is a risk factor for atherosclerosis and cardiovascular disease. The purpose of this study was to look at the description of the lipid profile at 3 months injection acceptors. The design of the study was descriptive. The population in this study was 76, the number of samples that met the inclusion and exclusion criteria in this study was 30. Examination of the lipid profile was carried out with an enzymatic colorimetric (cholesterol oxidase method / CHOD PAP). The results of lipid profile examination showed that 13.33% had high cholesterol levels, 3.33% had high triglyceride levels, 13.33% had high HDL levels, 20% had high LDL levels and 3.33% have very high LDL levels. The conclusion of this study was long term use of DMPA injection contraception could cause changes in the lipid profile, so it is recommended for acceptors who want to use contraception in the long term to use MKJP as an option so as not to affect the fat profile in the body.

Cardiovascular disease is a disease that is affected by the heart and blood vessels. There are several main risk factors that cause cardiovascular disease. Risk factors for cardiovascular disease include: high blood pressure, high cholesterol, diabetes, being overweight or obese, age, sex, smoking, and alcohol. The more risk factors you have, the greater the chance of causing cardiovascular disease. In this research, it was developed using the Spearman, Pearson and Kendall correlation methods to analyze data on cardiovascular disease patients. The results showed there was correlation between blood pressure (ap_hi and ap_lo), age, and cholesterol had a strong relationship with cardiovascular disease. Glucose and cholesterol levels also have a strong relationship between one another.

Important Amount

Hypercholesterolemia represents one key pathophysiological factor predisposing to increasing risk of developing cardiovascular disease worldwide. Controlling plasma cholesterol levels and other metabolic risk factors is of paramount importance to prevent the overall burden of disease emerging from cardiovascular-disease-related morbidity and mortality. Dietary cholesterol undergoes micellization and absorption in the small intestine, transport via blood, and uptake in the liver. An important amount of cholesterol originates from hepatic synthesis, and is secreted by the liver into bile together with bile acids (BA) and phospholipids, with all forming micelles and vesicles. In clinical medicine, dietary recommendations play a key role together with pharmacological interventions to counteract the adverse effects of chronic hypercholesterolemia. Bioactive compounds may also be part of initial dietary plans. Specifically, soybean contains proteins and peptides with biological activity on plasma cholesterol levels and this property makes soy proteins a functional food. Here, we discuss how soy proteins modulate lipid metabolism and reduce plasma cholesterol concentrations in humans, with potential outcomes in improving metabolic- and dyslipidemia-related conditions.

Cholesterol is critical for several cellular functions and essential for normal fetal development. Therefore, its metabolism is tightly controlled during all life stages. The liver X receptors-α (LXRα; NR1H3) and -β (LXRβ; NR1H2) are nuclear receptors that are of key relevance in coordinating cholesterol and fatty acid metabolism. The aim of this study was to elucidate whether fetal cholesterol metabolism can be influenced in utero via pharmacological activation of LXR and whether this would have long-term effects on cholesterol homeostasis. Administration of the LXR agonist T0901317 to pregnant mice via their diet (0.015% wt/wt) led to induced fetal hepatic expression levels of the cholesterol transporter genes Abcg5/g8 and Abca1, higher plasma cholesterol levels, and lower hepatic cholesterol levels compared with controls. These profound changes during fetal development did not affect cholesterol metabolism in adulthood nor did they influence coping with a high-fat/high-cholesterol diet. This study shows that the LXR system is functional in fetal mice and susceptible to pharmacological activation. Despite massive changes in fetal cholesterol metabolism, regulatory mechanisms involved in cholesterol metabolism return to a “normal” state in offspring and allow coping with a high-fat/high-cholesterol diet.

High plasma cholesterol levels increase the risk of cardiovascular disease (CVD). Transintestinal Cholesterol Excretion (TICE) is a recently emerged pathway of cholesterol removal and has the potential to lower plasma cholesterol levels and confer protection against CVD. Under control conditions, TICE accounts for about 30% of fecal cholesterol loss in mice. Using a panel of knock-out and transgenic mice as well as pharmacological manipulations we show that in mice TICE is regulated by intestinal activation of the Farnesoid X Receptor (FXR), via its target Fibroblast Growth Factor 15/19 (FGF15/19). Activation of FXR by the agonist PX20606 (PX) resulted in a >10-fold increased fecal cholesterol excretion as well as TICE and 40% reduced plasma cholesterol levels. The induction of fecal cholesterol excretion and TICE was absent in PX-treated intestine-specific FXR-null mice but was regained when those mice were co-treated with FGF19. Moreover, FGF19 treatment alone was sufficient to induce fecal cholesterol loss to a similar extend as was observed in PX-treated wild-type mice. PX treatment resulted in an increased muricholate/cholate-ratio and thereby induced a more hydrophilic bile salt pool. Not surprisingly, cholesterol absorption was reduced in PX-treated mice. However, experiments in which mice were co-treated with PX and the cholesterol absorption inhibitor ezetimibe revealed that the stimulating effect of PX on fecal neutral sterol excretion and TICE were completely independent of differences in cholesterol absorption. Of note, treatment of mice with a combination of PX and ezetimibe stimulated fecal cholesterol loss and TICE so strongly that those mice lost about 60% of their entire estimated body cholesterol content each day. The stimulation of fecal cholesterol loss and TICE by PX and PX/ezetimibe treatment was severely blunted in Abcg8-KO mice and this could not be restored by hepatic reintroduction of Abcg8, indicating a decisive role for intestinal ABCG5/G8 in PX-induced fecal cholesterol loss and TICE. Our data strongly suggest that hydrophilic bile acids stimulate ABCG5/G8 activity in the intestine, leading to an increased flux of cholesterol from the body into the intestinal lumen that is subsequently excreted with the feces.
