Lack of correlation between the apolipoprotein B XbaI polymorphism and blood lipid levels in a Swedish population

The possible connections between the apolipoprotein B (apo B) XbaI polymorphism and the serum levels of total cholesterol, triglycerides, LDL, HDL and apo B have been investigated among 187 randomly selected subjects from Gothenburg, Sweden. The interferences of age and sex on the serum lipoproteins and apo B concentrations were considered. Using multiple regression analysis, we compared the different lipid levels and the levels of apo B with the genotypes X1X1, X1X2 and X2X2 (X1 = without the XbaI restriction site, X2 = with the site), with age and with sex and with those factors combined with each other. A significantly higher concentration of serum cholesterol and LDL among men than among women was found and total serum cholesterol, LDL and apo B were positively correlated with age. The allele frequency of the XbaI polymorphism in the sample was 0.45 for the allele without the XbaI restriction site. No correlation was found between the apo B genotypes and the levels of serum lipoproteins or apo B.     

冠状动脉病变与血脂代谢异常的相关性

目的　探讨冠状动脉病变与血脂代谢紊乱的关系。方法　将2 6 7例疑似冠心病的患者依据冠状动脉造影结果分为对照组(非冠心病组) 1 0 1例,冠心病组1 6 6例,其中单支病变组54例,双支病变组6 8例,三支病变组4 4例,同时测定并统计分析血脂各成分及其比值与冠状动脉病变之间的关系。结果　冠心病(CHD)组总胆固醇(TC)、低密度脂蛋白胆固醇(LDL- C)、甘油三脂(TG)水平明显高于对照组,高密度脂蛋白胆固醇(HDL C)水平明显低于对照组,差异有统计学意义。随着冠状动脉病变范围的增加,TC、LDL C、载脂蛋白B(ApoB)、TC HDL- C、LDL- C HDL- C升高,HDL- C降低,与对照组比较,差异有统计学意义。冠心病组血脂各组分和其比值与冠状动脉积分的相关分析表明,TC HDL- C、LDL -C HDL -C与冠状动脉病变的相关性最强。结论　血脂代谢紊乱的严重程度与冠状动脉病变的严重程度是一致的,通过异常的血脂代谢有可能初步预测冠状动脉病变,其中LDL- C HDL- C、TC- HDL C比值优于其他血脂指标。     

Nutritional habits and serum lipid levels in a low-fat intake Chinese population sample

The dietary intake of macronutrients and of specific minerals and vitamins was measured in a low-fat intake adult population living in a rural area in northwestern China. The total intake of fat amounted to +/- 12% of total energy. The P/S ratio was 2.5 and the U/S ratio 3.8. Carbohydrates provide about 75% of total energy. The mean total serum cholesterol was 148 mg/dl in men and 163 mg/dl in women. The mean HDL-cholesterol level was 38.6 mg/dl in men and 39.4 mg/dl in women, confirming the absence of a significant sex difference in HDL-cholesterol in low-fat consuming populations. Triglyceride levels were similar to those of Western populations. For both sexes taken together a positive correlation was found between the serum cholesterol level and saturated fat intake (p < 0.001) and a negative correlation with the P/S ratio (p < 0.05). Calcium intake was low: 346 mg/d in men and 245 mg/d in women.     

Associations between serum lipoprotein(a) levels and the severity of coronary and aortic atherosclerosis

To elucidate the associations between Lp(a) levels and coronary and aortic atherosclerosis, we performed aortic MRI in 143 patients undergoing coronary angiography. Severity of aortic atherosclerosis was represented as plaque scores. Of the 143 patients, 104 had coronary artery disease (CAD). Thoracic and abdominal aortic plaques were found in 89 and 131 patients. Lp(a) levels increased stepwise with the number of stenotic coronary vessels: 15.7 (CAD(-)), 21.2 (1-vessel), 21.4 (2-vessel), and 22.9 mg/dl (3-vessel) (P<0.05). For aortic atherosclerosis, 143 patients were divided into quartiles by plaque scores. Lp(a) did not differ among quartiles of thoracic plaques: 17.1, 19.0, 23.5, and 21.2 mg/dl (P=NS), whereas Lp(a) increased stepwise with quartiles of abdominal plaques: 17.1, 19.2, 19.1, and 24.0 mg/dl (P<0.05). Lp(a) was an independent factor for CAD and abdominal aortic plaques, but not thoracic plaques. Thus, Lp(a) levels were associated with aortic atherosclerosis, especially in abdominal aorta, as well as coronary atherosclerosis.     

Serum lipid and apolipoprotein levels in a Nigerian population sample

Serum lipids and apoproteins have been measured in 307 men and 235 women living around Benin City in Nigeria. Total serum cholesterol values are low compared both to White Western populations and to American Blacks. HDL-cholesterol levels, however, are comparable to values in Western and Oriental men, but lower than in Western women. A highly significant correlation exists between total cholesterol and apo B and between HDL-cholesterol and apo A-I in men and women. The low serum lipid values are related to a low dietary fat intake, almost exclusively from palm oil, in the Nigerian population.     

Serum lipid and apolipoprotein levels in a Tibetan population sample

Serum lipid and apolipoprotein levels were measured in a Tibetan population sample. In both men and women serum cholesterol levels were markedly lower than in Western populations. In men HDL-cholesterol levels were higher compared to both Oriental and Western populations while in women the values were markedly higher than in other Oriental populations and similar to Western populations. Highly significant positive relationships were found between serum lipid levels and corresponding apolipoprotein levels. In men but not in women serum cholesterol was markedly higher in office workers than in factory workers.

Association between the severity of diabetes mellitus and coronary arterial atherosclerosis

The relation between the severity of diabetes mellitus (DM) and the risk of significant coronary artery lesions were studied in 7,655 patients undergoing coronary arteriography for suspected coronary artery disease (CAD) between 1972 and 1982. The principal treatment regimen for DM was used to estimate the severity of DM. DM treated with insulin was defined as the most severe (n = 244), followed by DM treated with oral agents (n = 344) and with diet only (n = 380); 6,687 patients did not have DM. Severity of DM in patients with CAD (70% or greater diameter stenosis) was compared with that in control subjects without CAD (0% stenosis) for each of 9 anatomic locations (proximal, middle and distal portions of right, anterior descending and circumflex coronary arteries) using a retrospective case-control approach. The risk of CAD was highest in patients with DM treated with insulin (odds ratio estimate of the relative risk [OR = 3.0]), followed by patients with DM treated with oral agents (OR = 1.8) and lastly in those treated with diet alone (OR = 1.4). Severity of DM was a significant (p less than 0.05) independent predictor of CAD in a multivariate logistic regression model, whereas age at onset and duration of DM were not. The relative risk of CAD was the same (p greater than 0.05) for each of the 9 coronary segments. The data suggest that the risk of CAD increases with the severity of DM, which was a stronger predictor of CAD than duration of DM.(ABSTRACT TRUNCATED AT 250 WORDS)

Absence of correlation between coronary arteria atherosclerosis and severity or duration of diabetes mellitus of adult onset

The relation between the severity and duration of diabetes mellitus and the severity of ischemic heart disease is uncertain. The clinical findings and the findings at autopsy were studied in 185 patients with diabetes mellitus of adult onset who ranged in age from 37 to 91 years and had a clinical diagnosis of diabetes established for a few days to 50 years before death. No statistically significant association was demonstrated either by simple correlation or by multivariate regression analysis between the clinically diagnosed severity or duration of diabetes and either the overall coronary disease, the number of diseased vessels or the number of myocardial infarctions. The presence of other expected correlations in the multivariate analysis suggested that the results of this study were not spurious. However, comparison with 185 age- and sex-matched control patients revealed that on the average, diabetic patients have more overall coronary disease (p < 0.002), more diffuseness of coronary disease (p < 0.005), more coronary collateralizatlon (p < 0.001), more vessels involved by atherosclerosis (p < 0.001) and more myocardial infarcts (p < 0.001). The results suggest that although diabetes mellitus of adult onset is a condition in which the larger coronary arteries are subject to more atherosclerosis than are those in nondiabetic subjects, the progression of the atherosclerotic disease is unrelated to the duration or severity of the diabetes mellitus.
