| Serum cholesterol reduction and cholesterol absorption inhibition in CaCo-2 cells by a soyprotein peptic hydrolyzate Nagaoka, S., T. Awano, et al. (1997), Biosci Biotechnol Biochem 61(2): 354-6. Abstract: The serum cholesterol level in rats was significantly decreased in a group fed on a soyprotein peptic hydrolyzate (SPH) when compared with a group fed on a casein tryptic hydrolyzate (CTH). The fecal excretion of total steroids was significantly greater with rats fed on the SPH diet when compared with the CTH diet. The results of CaCo-2 studies clearly suggest that the suppression of cholesterol absorption in the intestinal epithelia is part of the mechanism for the hypocholesterolemic action induced by SPH. |
| Serum cholesterol reduction with tamoxifen Schapira, D. V., N. B. Kumar, et al. (1990), Breast Cancer Res Treat 17(1): 3-7. Abstract: The serum cholesterol levels of 123 consecutively and newly diagnosed women with Stage I and II breast cancer taking tamoxifen were compared with a control group of 81 consecutively newly diagnosed women with Stage I and II breast cancer who were not taking a hormonal treatment or supplement. Other factors that were evaluated were age, menopausal status, tumor size, weight, height, Quetelet index, and smoking and alcohol intake history. The mean cholesterol change in patients on tamoxifen (34.2 +/- 3.6 mg/dl) was significantly greater than controls (1.0 +/- 4.1 mg/dl) (P less than 0.001). Serum cholesterol fell by more than 10 mg/dl in 72.9% of women on tamoxifen vs. 35.1% of controls and by more than 40 mg/dl in 39.9% of women on tamoxifen vs. 12.6% of controls. Multivariate analysis revealed that tamoxifen administration (P less than 0.0001), initial cholesterol level (P = 0.001), and age (P = 0.04) were significant factors in producing a decrease in serum cholesterol. The administration of tamoxifen as adjuvant therapy to women with newly diagnosed breast cancer resulted in a significant fall in serum cholesterol. This effect of tamoxifen on the serum cholesterol may prove to be an additional benefit in the form of reduced cardiovascular risk in these women. |
| Serum cholesterol response to replacing butter with a new trans-free margarine in hypercholesterolemic subjects Tonstad, S., E. C. Strom, et al. (2001), Nutr Metab Cardiovasc Dis 11(5): 320-6. Abstract: Margarine leads to lower total and LDL cholesterol (LDL-C) levels than butter but may contain trans fatty acids that increase atherogenic lipids. A food company has used data concerning the cholesterolemic effects of individual fatty acids, including trans fatty acids, to develop a commercially available and virtually trans-free margarine. OBJECTIVE: The effect of this novel margarine on serum lipids and lipoproteins was compared with that of butter in free-living, hypercholesterolemic subjects. DESIGN AND SETTING: A two-period, outpatient cross-over trial at a university hospital lipid clinic. SUBJECTS: The study involved 77 subjects, and was completed by 53 men and 19 women aged 35-65 years with total serum cholesterol levels of between 6.0 and 7.9 mmol/L. INTERVENTION: Two 23-day regimens, separated by a 4-week washout period, included individualised dietary prescriptions supplemented with butter or margarine designed to provide 15% of total dietary energy. RESULTS: In comparison with butter, margarine intake lowered total and LDL-C levels by respectively 11.1% (99% CI: 8.1-14.1) and 11.3% (99% CI: 7.6-15.1). The reduction in LDL-C was < 3% in nearly one-fifth of the subjects despite appropriate changes in serum triglyceride fatty acids. Of the tested clinical and demographic variables, only the percentage of energy obtained from saturated fat during the margarine intake period was associated with dietary responsiveness (explaining 12% of the variation; p < 0.01). CONCLUSION: Our results suggest that a margarine designed to meet nutritional recommendations for hypercholesterolemia is more efficacious than butter in reducing atherogenic lipid levels in hypercholesterolemic subjects. |
| Serum cholesterol trends among members of the Finnish parliament Nikkari, S. T., P. Oksa, et al. (1999), Prev Med 28(3): 260-3. Abstract: BACKGROUND. Mortality from coronary heart disease in Finland has declined remarkably since the early 1970s. Most of the change has apparently been due to the active national strategy for reduction of serum cholesterol levels. This study was undertaken to estimate to what extent members of the Finnish parliament (MPs) have complied with the national recommendations. METHODS: Serum total and HDL cholesterol values were measured from MPs of three subsequent parliaments elected in 1987, 1991, and 1995. RESULTS: From 1987 to 1995, the Finnish MPs showed a reduction of serum total cholesterol that was significant among males (-5.2;%, P < 0.05) but not among females (-6.4%, NS) and was somewhat smaller than the reduction in the general population during 1987 to 1997 (-9.4% among males and -8. 3% among females). The male MPs had a 14% rise in HDL cholesterol (P < 0.01), while among female MPs and in the general population it decreased by 3.1 to 3.8% (all NS). The cholesterol levels of female MPs were altogether a little lower than in the general population. The Finnish MPs tended to have lower total cholesterol levels compared with those reported from Hungarian MPs. CONCLUSION: The favorable change in the lipid profile of members of the Finnish parliament indicates that they have personally been involved in the national change process. Follow-up of risk factors in national decision-makers is a useful part of comprehensive monitoring of national coronary heart disease prevention activity. |
| Serum cholesterol, APOE genotype, and the risk of Alzheimer's disease: a population-based study of African Americans Evans, R. M., C. L. Emsley, et al. (2000), Neurology 54(1): 240-2. Abstract: A significant interaction among total serum cholesterol (TC), APOE genotype, and AD risk was found in a population-based study of elderly African Americans. Increasing TC was associated with increased AD risk in the group with no epsilon4 alleles, whereas TC was not associated with increased AD risk in the group with one or more epsilon4 alleles. Further study of the relationship between cholesterol and APOE genotype is needed to confirm this association, but the results suggest that cholesterol may be a potentially modifiable environmental risk factor for AD. |
| Serum cholesterol, beta-carotene, and risk of lung cancer Shekelle, R. B., C. C. Tangney, et al. (1992), Epidemiology 3(4): 282-7. Abstract: This paper hypothesizes that beta-carotene mediates the association between low serum cholesterol and increased risk of lung cancer, predicts that the association should be greater in population strata with low intake of beta-carotene than in those with high intake if the hypothesis is correct, and investigates this prediction with data from a 24-year cohort study of 1,960 middle-aged employed men. In the total cohort, serum cholesterol was not related to risk of lung cancer. The relative risk associated with a difference of -1.0 mmol per liter in serum cholesterol was 1.01 (95% confidence interval of 0.80-1.27) after adjustment for cigarette smoking, age, and intake of beta-carotene. In contrast, however, when the study group was restricted to men with intake of beta-carotene less than 5,000 (N = 929) or less than 3,000 IU per day (N = 272), comparable relative risks were 1.10 and 1.21, respectively. Although the 95% confidence intervals for these relative risks were broad and included unity, the result is consistent with expectation. We conclude that the hypothesis warrants further investigation. |
| Serum cholesterol, blood pressure, cigarette smoking, and death from coronary heart disease. Overall findings and differences by age for 316,099 white men. Multiple Risk Factor Intervention Trial Research Group Neaton, J. D. and D. Wentworth (1992), Arch Intern Med 152(1): 56-64. Abstract: To assess the combined influence of blood pressure (BP), serum cholesterol level, and cigarette smoking on death from coronary heart disease (CHD) and to describe how these associations vary with age, data on those factors and on mortality for 316,099 men screened for the Multiple Risk Factor Intervention Trial (MRFIT) were examined. Vital status of participants has been determined after an average follow-up of 12 years; 6327 deaths from CHD have been identified. Strong graded relationships between serum cholesterol levels above 4.65 mmol/L (180 mg/dL), systolic BP above 110 mm Hg, and diastolic BP above 70 mm Hg and mortality due to CHD were evident. Smokers with serum cholesterol and systolic BP levels in the highest quintiles had CHD death rates that were approximately 20 times greater than nonsmoking men with systolic BP and cholesterol levels in the lowest quintile. Systolic and diastolic BP, serum cholesterol level, and cigarettes per day were significant predictors of death due to CHD in all age groups. Systolic BP was a stronger predictor than diastolic BP. These results, together with the findings of clinical trials, offer strong support for intensified preventive efforts in all age groups. |
| Serum cholesterol, cholesterol precursors and plant sterols in different inflammatory bowel diseases Hakala, K., M. Vuoristo, et al. (1996), Digestion 57(2): 83-9. Abstract: The role of cholestasis and ileal dysfunction on sterol metabolism was studied in 79 patients with inflammatory bowel diseases (IBDs) and in 23 irritable bowel syndrome (IBS) controls by determining serum sterol/cholesterol proportions. The sterols included cholesterol precursors (delta 8-cholestenol, desmosterol and lathosterol), markers of cholesterol synthesis, cholestanol and plant sterols (campesterol and sitosterol), markers of cholesterol absorption and biliary secretion. The IBD patients were subgrouped into distal ulcerative colitis (dUC, n = 21), pancolitis (pUC, n = 29), ileal Crohn's disease (iCD, n = 20) and colonic Crohn's disease (cCD, n = 9). The cholestanol proportions were increased in the 3 colonic IBD groups, up to two times in cCD patients and seven times in a case with clinically overt primary sclerosing cholangitis, but were within the control IBS levels in the patients with iCD. The sitosterol, but not campesterol, proportion was significantly increased only in the pUC group. In the iCD group only the serum precursor sterol proportions, especially those for delta 8-cholestenol and lathosterol, were elevated probably due to ileal dysfunction induced bile acid malabsorption and compensatorily increased cholesterol synthesis. In conclusion, the findings suggest that the increased cholestanol proportion in colonic IBD is determined mainly by impaired biliary elimination of this sterol, while in ileal affision the dominating change in sterol balance is activated cholesterol synthesis. Thus increased serum cholestanol is a novel finding in colonic IBD, apparently indicating the presence of subclinical cholestasis in a marked number (20-50%) of IBD patients. |
| Serum cholesterol, cholesterol precursors, and plant sterols in hypercholesterolemic subjects with different apoE phenotypes during dietary sitostanol ester treatment Vanhanen, H. T., S. Blomqvist, et al. (1993), J Lipid Res 34(9): 1535-44. Abstract: A randomized double-blind study was made in 67 modestly hypercholesterolemic subjects by replacing 50 g of daily dietary fat by the same amount of a rapeseed oil preparation without and with fat-soluble sitostanol esters. The diet became relatively rich in dietary fat (37%) especially in subjects with a low basal calorie intake. The esters were prepared by transesterification of sitostanol with rapeseed oil fatty acids. The effects of sitostanol esters were studied on serum cholesterol and cholesterol synthesis (measuring cholesterol precursors in serum) and absorption (measuring serum plant sterols). The results were related to different apoE phenotypes. A 6-week regimen of about 3.4 g/day of sitostanol lowered total and low density lipoprotein (LDL) cholesterol levels by 7.5% and 10%, respectively, over that due to rapeseed oil alone. High density lipoprotein (HDL) cholesterol and triglyceride concentrations were unchanged. Thus, the HDL/LDL cholesterol ratio was significantly increased. The decrease in LDL cholesterol level was more consistent in subjects with the epsilon 4 allele than in those with homozygous epsilon 3 alleles. Sitostanol markedly decreased serum campesterol (-46%) and sitosterol (-30%), especially in subjects with the epsilon 4 alleles known to have high cholesterol absorption. The decreases of LDL cholesterol and plant sterols were interrelated, suggesting that reduced cholesterol absorption contributed to the lowering of LDL cholesterol. Serum sitostanol was unchanged, while the serum cholesterol precursors, delta 8-cholestenol, desmosterol, and lathosterol, were compensatorily increased by 10% (P < 0.05), most consistently in the subjects with epsilon 4 alleles, indicating an increase in cholesterol synthesis. The study demonstrates that sitostanol esters dissolved in dietary fat can be recommended for treatment of modest primary hypercholesterolemia and are apparently practical and suitable for cholesterol lowering in a general population. |
| Serum cholesterol, cholesteryl ester, and high-density lipoprotein development in newborn infants: response to formulas supplemented with cholesterol and gamma-linolenic acid Van Biervliet, J. P., N. Vinaimont, et al. (1992), J Pediatr 120(4 Pt 2): S101-8. Abstract: Healthy newborn infants were either breast-fed or randomly designated to receive a standard formula, formula plus cholesterol, or formula plus gamma-linolenic acid at birth. At 0, 7, and 30 days of life, the following variables were measured: cholesteryl esters (cholesteryl arachidonate, cholesteryl oleate, cholesteryl palmitate, and cholesteryl linoleate), high-density lipoprotein (HDL) cholesterol, apoproteins (A-I, A-II, B, C-II, C-III, and E), and the cholesterol and apoprotein A-I content of the HDL subfractions HDL-2b, HDL-(2a + 3a), and HDL-(3b + 3c). Breast-fed infants had higher serum levels of cholesterol, cholesteryl oleate, cholesteryl palmitate, cholesteryl arachidonate, and HDL-2b than had formula-fed infants. Addition of gamma-linolenic acid to formula raised cholesteryl-arachidonate levels, and cholesterol and gamma-linolenic acid raised serum HDL-2b levels compared with those produced by unsupplemented formula. Our data suggest that both exogenous cholesterol and gamma-linolenic acid contribute to the maturation of HDL particles associated with human milk consumption in newborn infants. They may also promote adequate delivery of cholesterol and arachidonic acid to the developing brain. |
| Serum cholesterol, high-density lipoprotein cholesterol and five-year survival in elderly people Nikkila, M. and J. Heikkinen (1990), Age Ageing 19(6): 403-8. Abstract: In the year 1982 serum cholesterol and high-density lipoprotein (HDL) cholesterol were measured in 535 people aged 85 years participating in a health survey screening. All subjects were living at home. During the 5-year follow-up, 186 (34.8%) of the subjects died. There was a J-shaped relation between serum cholesterol and mortality. Mortality was lowest at serum cholesterol 5.0-5.9 mmol/l for men and 7.0-7.9 mmol/l for women. The greatest mortality was observed in men with cholesterol greater than or equal to 6.0 mmol/l and in women with cholesterol greater than or equal to 8.0 mmol/l. There was a significant negative association of serum HDL cholesterol with mortality. Mortality was highest (53.3%) in men with serum HDL cholesterol less than 0.80 mmol/l. Mortality was low (16.5%) in women with serum HDL cholesterol greater than 1.8 mmol/l. |

| Serum cholesterol, precursors and metabolites and cognitive performance in an aging population Teunissen, C. E., J. De Vente, et al. (2003), Neurobiol Aging 24(1): 147-55. Abstract: The present study investigated if a causal relation exists between serum concentrations of precursors and metabolites of cholesterol and cognitive performance in a healthy aging population.Cognitive function addressing four domains of 144 individuals (30-80 years) was tested at baseline and after 6 years of follow-up. Serum concentrations of different sterols related to cholesterol were measured.Serum levels of lathosterol and lanosterol correlated negatively with cognitive performance on the Word Learning tests for verbal learning and memory. This was observed at baseline and follow-up and was independent of age, sex and educational level. Furthermore, the levels of lathosterol and lanosterol at baseline correlated with performance on the Stroop test and Word Learning tests over the 6-year follow-up period. Serum levels of 27-hydroxycholesterol and 24S-hydroxycholesterol showed inconsistent correlations, while cholesterol, desmosterol, sitosterol and campesterol were not related to cognitive performance.Thus, relative high serum ratios of the cholesterol precursors lanosterol and lathosterol, indicative for a high rate of endogenous cholesterol synthesis, are associated with relatively low memory performance in this aging population. |
| Serum cholesterol, suicidal behavior and impulsivity in cocaine-dependent patients Roy, A., B. Gonzalez, et al. (2001), Psychiatry Res 101(3): 243-7. Abstract: Relationships between serum cholesterol and suicidal behavior have been reported. As suicidal behavior is common in cocaine dependence, we looked for a relationship with serum cholesterol. To do this, we compared 57 cocaine-dependent patients who had attempted suicide with 111 cocaine-dependent patients who had never attempted suicide for their admission total serum cholesterol levels. We found that there were no significant differences between cocaine-dependent patients who had or had not attempted suicide in their total serum cholesterol levels. Also, there were no significant correlations between total serum cholesterol levels and scores on the Barratt Impulsivity Scale. Thus, admission total serum cholesterol does not appear to be clinically useful in the assessment of suicidal behavior in cocaine-dependent patients. |
| Serum cholesterol, suicidal tendencies, impulsivity, aggression, and depression in adolescent psychiatric inpatients Apter, A., N. Laufer, et al. (1999), Biol Psychiatry 46(4): 532-41. Abstract: BACKGROUND: This study was undertaken to examine the relationship between serum cholesterol levels and suicidal behaviors in adolescent psychiatric inpatients. Any association between serum cholesterol and measures of suicidal behavior, impulsivity, aggression, anxiety, and depression was also examined. METHODS: Consecutive admissions (n = 152) to an adolescent psychiatric inpatient unit were assessed using measures of suicidal behavior, violence, impulsivity, and depression. Serum cholesterol was compared between those admitted for reasons of suicidal tendencies and those for other reasons. Correlation between serum cholesterol and measures of suicidal behavior, violence, impulsivity, and depression were examined. RESULTS: Serum cholesterol levels were significantly higher in adolescent patients who were currently suicidal than in nonsuicidal adolescents. Within the suicidal group, but not in the total inpatient group, serum cholesterol correlated negatively with the degree of suicidal behavior. No correlation between serum cholesterol levels and depression, violence, and impulsivity were detected. No significant differences were found in serum cholesterol levels between diagnoses or between suicidal and nonsuicidal patients within each diagnostic group. CONCLUSIONS: The association between cholesterol and suicidal tendencies remains complex and may depend on several variables within the population studied. Its usefulness as a biologic risk factor in clinical samples remains to be determined. |
| Serum cholesterol, triglyceride, VLDL-c, LDL-c, and HDL-c levels in healthy children Bahar, A., U. Sevgican, et al. (2003), Tohoku J Exp Med 201(2): 75-80. Abstract: The aim of this study is to determine the normal values of serum cholesterol, triglyceride, VLDL-C, LDL-C, and HDL-C to obtain the reference values for diagnostic tests in healthy children. The study group included 420 healthy children (209 male, 211 female) ranging from 0 to 15 years. The cases were divided in 4 groups of age: 0-12 month (Group I), 13 month-6 year (Group II), 7-11 year (Group III), and 12-15 year (Group IV). Mean cholesterol, triglyceride, HDL-C, LDL-C and VLDL-C levels were 102.01 +/- 27.91, 96.32 +/- 37.57, 32.13 +/- 11.69, 46.64 +/- 21.97 and 24.19m +/- 10.56 in group I, 142. 58 +/- 30.12, 91.57 +/- 37.27, 45.68 +/- 13.86, 78.41 +/- 32.23 and 21.55 +/- 10.75 in group II, 139.85 +/- 28.06, 95.42 +/- 43.12, 46.04 +/- 14.03, 71.44 +/- 27.05 and 21.69 +/- 12.51 in group III, and 153.98 +/- 26.71, 101.72 +/- 46.66, 45.84 +/- 13.06, 83.33 +/- 27.25 and 25.17 +/- 12.66 in group IV, respectively. There is no significant difference in serum lipid levels between males and females in any age groups. Mean values of cholesterol, HDL-C and LDL-C are significantly higher in older age group. |
| Serum cholesterol, triglycerides, and aggression in the general population Fowkes, F. G., G. C. Leng, et al. (1992), Lancet 340(8826): 995-8. Abstract: A higher than expected number of violent deaths and suicides in coronary prevention trials has provoked interest in the possibility that low serum cholesterol concentrations are associated in the general population with personality characteristics predisposing to aggressive and suicidal behaviour. We have investigated this possibility in the Edinburgh Artery Study. We measured serum lipid concentrations in blood samples taken from fasting subjects and assessed personality characteristics on the Bedford Foulds Personality Deviance Scales in a random sample of 1592 men and women aged 55-74 years, selected from age-sex registers of ten general practices in Edinburgh. Serum cholesterol concentration was not significantly associated with aggression in men, but it was associated in multivariate analysis (though not univariate analysis) with denigratory attitudes towards others among women. However, serum triglyceride concentration was related, especially in men, to hostile acts (r = 0.13, p < 0.001) and domineering attitude (r = 0.12, p < 0.001) independently of age, total and HDL cholesterol, cigarette smoking, and alcohol consumption. Subjects taking part in prevention trials have higher triglyceride concentrations than the general population and the relation between serum triglyceride concentration and aggression merits further investigation. |
| Serum cholesterol, triglycerides, HDL and LDL in aggressive elderly patients with dementia Scheffel, A. (1996), Psychiatr Pol 30(1): 159-70. Abstract: Associations were analysed between serum concentrations of cholesterol, triglycerides, HDL and LDL measured after hospital admission, and physical aggression in a sample of elderly patients with dementia (210 women and 160 men). A significant lower serum cholesterol and LDL concentration were found in aggressive patients of both sexes and a significant lower serum triglycerides only in aggressive women. In the subgroups of Alzheimer type dementia, women showed significant lower serum triglycerides, and aggressive men significant lower LDL concentration compared with non-aggressive controls. There were no significant differences in serum HDL between aggressive and non-aggressive patients. |
| Serum cholesterol, uric acid and cholinesterase in victims of the Tokyo subway sarin poisoning: a relation with post-traumatic stress disorder Tochigi, M., T. Umekage, et al. (2002), Neurosci Res 44(3): 267-72. Abstract: Cholesterol and uric acid, which might correlate with steroidogenesis and monoamine functions, may change under emotionally stressful conditions and in mental disturbances. Among anxiety disorders, an increase of serum cholesterol has been observed in panic disorder. However, the issue has not been adequately investigated in other anxiety disorders, including post-traumatic stress disorder (PTSD). The present study investigated serum cholesterols, uric acid and cholinesterase in victims of the Tokyo subway sarin poisoning, 1995, in a series of 5-year follow-ups. Cholinesterase was studied, in relevance with serum lipid changes and symptoms of PTSD, and also in light of a biological effect of sarin. Out of 34 victims, eight developed PTSD and two were currently diagnosed with PTSD using the Clinician-Administered PTSD Scale (CAPS). No significant relationship was observed between PTSD and serum cholesterols or uric acid. Several factors including co-occurrence of other mental disturbances with PTSD, in addition to the limited sample size, might have affected the result. In contrast, serum cholinesterase level was significantly reduced in the victims with the development of PTSD, compared with the matched controls (P<0.02, t-test). This might partly reflect a long-term remnant effect of sarin intoxication, although an effect of the psychological experience could not be totally excluded. |
