Obese children lipid profile: effects of hypocaloric diet and aerobic physical exercise

Diet and exercise help improve obese adults' lipid profile. However, their effect on obese children, the aim of the present study, is poorly known. Fifty obese children were studied into 2 paired groups: Group D (1,500 - 1,800 kcal diet: 55% carbohydrate, 30% fat, 15% protein), and Group DE (same diet + aerobic physical activity 1 hour/day 3 times a week). After 5 months BMI, triglycerides, total cholesterol (TC) and fractions were assessed. No change in triglycerides, TC and low-density lipoprotein cholesterol (LDL-C) levels were reported in both groups. However, high-density lipoprotein cholesterol (HDL-C) increased (+10.3%; p< 0.01) only in DE Group. Screening patients with TC > 170 mg/dL, LDL-C > 110 mg/dL and HDL-C < 35 mg/dL we had: similar reduction for TC in both groups (-6.0% x -6.0%; p= ns), LDL-C reduction in both groups (-14.2% x -13.5%; p= ns), and HDL-C increase only in DE Group (+10.0%; p< 0.05). CONCLUSIONS: 1) Hypocaloric diet (HD) + exercise, rather than diet only, increase obese children's HDL-C levels irrespective of baseline levels; 2) HD only and HD + exercise lead to TC and LDL-C reduction in obese children with TC and LDL-C above normal values.     

血清胆红素和血脂的综合指数与冠心病的关系研究

目的探讨血清胆红素与血脂的综合指数与冠心病(CHD)的关系.方法将80名行冠状动脉造影术的患者分为2组:CHD组与对照组(冠状动脉正常).测定血清总胆红素水平(TBIL),总胆固醇(TC),高密度脂蛋白胆固醇(HDL-C),低密度脂蛋白胆固醇(LDL-C),计算出其综合指数:LDL-C/(HDL-C TBIL)和TC/(HDL-C TBIL),分析其与CHD之间的关系.结果CHD患者血清TBIL水平明显低于非冠心病患者(P＜0.05).CHD患者总胆固醇(TC),低密度脂蛋白胆固醇(LDL-C),LDL-C/(HDL-C TBIL)比值,TC/(HDL-C TBIL)比值水平明显高于冠状动脉正常组(P＜0.05).进行Logistic回归分析,TC,LDL-C,LDL-C/(HDL-C TBIL),TC/(HDL-C TBIL)可引入Logistic回归模型,它们为CHD的危险因素.结论CHD的发生与TBIL的降低有一定的相关性,综合考虑血脂、血清胆红素与血脂的综合指数有助于CHD的诊断.

Serum cholesterol and high density lipoprotein cholesterol distributions in patients with acute myocardial infarction and in the general population of Kuopio Province,Eastern Finland

Abstract. As part of the FINMONICA project, serum total cholesterol (TC) and high density lipoprotein cholesterol (HDLC) concentrations were determined in 1216 AMI patients (937 men. 279 women) aged 35–64 years in the province of Kuopio in eastern Finland during the 5-year period 1983–87. The distributions were compared with the corresponding distributions in a representative sample of the general population of the same area (1026 men, 1021 women). The mean serum TC levels did not differ between the AMI patients and the normal population. Only the prevalence of a very high serum TC level (> 8.0 mmol l^?1) among women was significantly higher in the AMI group than in the population sample. On the other hand, in both sexes the age-adjusted mean HDLC was significantly lower in the AMI group than in the population sample. Our findings emphasize the importance of HDLC measurement as a part of the assessment of the lipid risk factor profile in patients with AMI.

Attenuation of the development of hypercholesterolemic atherosclerosis by thymoquinone

Thymoquinone (TQ), derived from Nigella sativa seed, is an antioxidant. The present study investigated whether TQ attenuates the development of atherosclerosis, and/or reduces the serum lipid levels and oxidative stress in rabbits. New Zealand white female rabbits were assigned to four groups of six animals each: group I, control; group II, 1% cholesterol diet; group III, 1% cholesterol plus TQ (10 mg/kg/day; through a nasogastric tube) diet; and group IV, 1% cholesterol plus TQ (20 mg/kg/day; through a nasogastric tube) diet. Blood samples were collected at baseline and after four and eight weeks on the experimental diets for measurement of serum lipids, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), TC/HDL-C ratio and oxidative stress biomarkers (malondialdehyde [MDA] and protein carbonyls). At the end of the eight weeks, the aorta was removed for the assessment of atherosclerotic changes, MDA and protein carbonyls. Group II animals developed atherosclerosis (45%±11% of the intimal surface of aorta was covered with atherosclerotic plaques), which was associated with an increase in the serum TC, TG, LDL-C, HDL-C, TC/HDL-C, MDA and protein carbonyls. In group III, TQ decreased serum TC, LDL-C, MDA and protein carbonyls by 26%, 29%, 85% and 62%, respectively, and aortic MDA by 73%, which was associated with a 40% reduction of the development of aortic atherosclerosis. The higher dose of TQ in group IV had effects similar to the lower dose (group III), except that this dose further decreased serum TG. It is concluded that TQ attenuates hypercholesterolemic atherosclerosis and this effect is associated with a decrease in serum lipids and oxidative stress.     

Lipid profile of children with a family history of coronary heart disease or hyperlipidemia: 9-year experience of an outpatient clinic for the prevention of cardiovascular diseases

The authors evaluated the lipid profile of children with a positive family history of coronary heart disease (CHD), cerebrovascular disease (CVD), or hyperlipidemia and compared them with controls in order to identify risk indicators for atherosclerosis. A group of 315 children (group A) aged more than 2 years old with a positive family history were evaluated for serum concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), apolipoprotein B100 (ApoB100), apolipoprotein A1 (Apo A1), and lipoprotein (a) (Lp[a]). These values were compared with the levels of a control group of 214 children of comparable age (group B). The median age of children in groups A and B was 10.6 (range 2.3-16) and 9.8 (range 3-13.7) years of age, respectively. Among these children, 196 (52%), 47 (12.5%), and 72 (19.1%) had a positive family history of CHD (group A1), cerebrovascular disease (CVD) (group A2), and hypercholesterolemia (group A3), respectively. We identified 8 children with genetically determined dyslipidemia: 2 children with homozygous and 6 with heterozygous familial hypercholesterolemia. Children in group A3 had significantly higher concentrations of TC, TG, LDL-C, and ApoB100 and lower concentrations of Apo A1 compared with controls, while no significant differences were found in concentrations of lipid variables among children of group A1, A2, and A3. Significant differences were also noted in the concentrations of TC, LDL-C, and Lp(a) between children of group A1 and controls. Screening the progeny of young patients with CHD or familial hypercholesterolemia can identify children at excessive risk for future vascular disease.

Dyslipoproteinemia in patients with active rheumatoid arthritis: effects of disease activity, sex, and menopausal status on lipid profiles

OBJECTIVE: To investigate the lipid profiles in patients with active rheumatoid arthritis (RA) and to assess the relationship of inflammatory disease activity markers, sex, and menopausal status with lipid profiles. METHODS: Three groups of patients with active RA (n = 184) were studied: men (n = 61, mean age 50.8 +/- 4.81 yrs), premenopausal women (n = 58, mean age 39.2 +/- 2.44 yrs), and postmenopausal women (n = 65, mean age 60.4 +/- 2.14 yrs), and healthy controls (n = 161): men (n = 65, mean age 50.9 +/- 3.42 yrs), premenopausal women (n = 47, mean age 40.3 +/- 1.66 yrs), and postmenopausal women (n = 49, mean age 61.3 +/- 3.16 yrs). We measured fasting plasma levels of total cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), lipoprotein (a) [LP(a)], apolipoprotein A1 (apo A1), apolipoprotein B (apo B), and erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). RESULTS: Male RA patients had significantly higher apo B/apo A1 and LP(a) and lower HDL-C than male controls. Female RA patients had significantly higher TC, LDL-C, and LP(a) than female controls. Premenopausal RA patients had significantly higher LDL-C, TC/HDL-C, LDL-C/HDL-C, and apo B/apo A1 and lower TG and HDL-C than premenopausal controls. Postmenopausal RA women had significantly higher TG and LP(a) and lower TC than postmenopausal controls. Female RA patients had higher HDL-C, apo A1, and TC/HDL-C and lower apo B/apo A1 than male RA patients. Postmenopausal RA patients had significantly higher TC, TG, TC/HDL-C, apo B, LP(a), and LDL-C/HDL-C than premenopausal RA patients. CRP correlated positively with TC/HDL-C, LDL-C/HDL-C, and apo B/apo A1 and negatively with HDL-C in male RA patients. In female RA patients CRP had positive correlation with TC/HDL-C and LDL-C/HDL-C and negative correlation with HDL-C. CONCLUSION: These findings suggest that patients with active RA have altered lipid profiles and that disease activity, sex, and menopausal status affect lipid profiles, and these would be expected to change the pattern of atherosclerotic events in RA.
