The National Cholesterol Education Program's guidelines for the detection, evaluation, and treatment of high serum cholesterol in adults were employed in screening 155 Southeast Asian refugees in a primary care clinic in Seattle, Washington. In order to determine the need for a therapeutic intervention, information also was collected on the presence of other coronary heart disease (CHD) risk factors. Male gender (39%), cigarette smoking (27%) and hypertension (26%) were the most common CHD risk factors; diabetes mellitus, obesity, a family or prior history of CHD or cerebral/peripheral vascular disease were each noted in less than 10%. The mean serum total cholesterol was 194 mg/dl. Thirty-seven (24%) patients required further lipoprotein analysis based on cholesterol level, history of CHD and risk factors for CHD. Twenty-one (66%) of 32 patients who underwent lipoprotein analysis (14% of all patients) were candidates for a therapeutic intervention for hypercholesterolaemia. Additionally, 14 (44%) patients undergoing lipoprotein analysis had depressed high-density lipoprotein levels (< 35 mg/dl). We conclude that CHD risk factors including hypercholesterolaemia are common in Southeast Asian refugee clinic patients and that in many, a therapeutic intervention may well be justified. Southeast Asian refugees should be routinely screened for hypercholesterolaemia and other CHD risk factors in accordance with the National Cholesterol Education Program's guidelines.

This present study is one part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetes mellitus in a population of the metropolitan area of S. Paulo, Brazil" undertaken in Cotia county. An alimentary inquiry based on the alimentary history of the individual was carried out among a subsample of the population (568 individuals). The objectives of the inquiry are the following: a) the identification of the atherogenic potential of the diets of different human groups, stratified according to social class and b) the analysis of consumption differentials of some nutrients, which confer atherogenicity to the diet, as between social classes. The consumption differentials were analyzed as between men and women, by social class and taking the 50th percentile (P50) of the sample as the standard of reference, with regard to the following dietary constituents: energy, total proteins, proteins of animal origin, percentages of protein calories (P%), fatty acids, fats (F%) and carbohydrates (CH%). Also, according to this criterion, some diet profiles were analyzed in the light of the recommendations of the National Cholesterol Education Program (NEP) as regards the calorie supplied by fats (F%), saturated fatty acids (SFA%), carbohydrates (CH%) and cholesterol (> 300 mg/day). The following were the findings obtained: the consumption differentials were more pronounced among the men. The social class which presented the largest percentages above the P50 of the sample, with regard to energy, total proteins, fats and carbohydrates, were the non-specialized workers, i.e. the manual laborers who have a high expenditure of energy, an that of small property owners and shop-keepers who lead a sedentary life. The class of the greatest acquisitive power and highest educational level presented a moderate consumption of these constituents. On the other hand, the consumption of the proteins of animal origin, above the P50, among men and women, maintained a direct relationship with socioeconomic level. The proportion of calories coming from fats (F%) and protein (P%) was directly proportional to the acquisitive power of the class, while that of carbohydrates (CH%) presented an inverse relationship. On the other hand, the consumption of cholesterol in excess of 300 mg/day was found to between 37 and 50% and 20 and 32% for men and women, respectively. The percentage of diets with more than 30% of calories coming from fats (F%) varied from 25 to 40% for men and 45 to 50% for women. The participation of the saturated fatty acids (SFA%) in proportions greater or equal to 10 was relatively low for both sexes: being of 5 to 17% for the men and of less than 10% for the women. The percentages of cases in the relationship saturated to unsaturated fatty acids (SFA/UFA) maintaining values less than 1% was also low for the population in general, being of 7 and 22% for the men and less than 10% for the women. It is concluded that diet probably is an important risk factor in cardiovascular diseases, lipemic disorders, obesity and hypertension, for a large part of the population, mainly for the small property owners and shop-keepers, is viable.

The study described was conducted to evaluate a simple enzymatic method for the study of the cholesterol/phospholipids ratio in erythrocyte membrane (C/PL) in a group of normal pregnant, of hypertensive pregnant, in non-pregnant controls and in cord blood. Subjects consisted of 28 normotensive pregnant women (NT), 14 women with pregnancy induced hypertension (PIH), 10 non-pregnant normotensive women (Non-Preg) and 14 samples obtained from umbilical cord (C) at delivery from normotensive pregnant. Red blood cells were isolated from heparinated blood samples. Lipids were extracted from erythrocytes by isopropanol/chloroform, without preparation of cell ghosts. Cholesterol content was evaluated by cholesterol oxidase and phospholipids were estimated as organic phosphorus in the total lipid extract. We found a significant difference of C/PL between the PIH group and the NT group (1.01, SD 0.11 vs. 0.76, SD 0.10, 95% CI 0.74-0.78; p < 0.001) and the Non-Preg group (0.83, SD 0.11, 95% CI 0.80-0.86; p < 0.001). Cord blood C/PL was significantly elevated with respect to NT (1.25, SD 0.13 vs. 0.76, SD 0.10; p < 0.001). The method was proven to be fast, reliable and of value for the study of the pathophysiology of the alteration of the lipid composition, i.e., the increased cholesterol content, of the red cell membrane found in hypertensive pregnant patients.

Coronary heart disease (CHD) remains the number one killer in the United States. This article summarizes the recommendations for cholesterol screening of children and adolescents by the American Academy of Pediatrics and the Expert Panel on Blood Cholesterol Levels in Children and Adolescents. Screening of children and adolescents is selective, and the determination to screen is based on past medical, family health, and health behavior histories. Children or adolescents with a family history of peripheral vascular disease or coronary artery disease in primary relatives under 55 years of age, or parents with high blood cholesterol levels, are considered to be at risk for high blood cholesterol and in need of screening. Children or adolescents who are obese, inactive, have hypertension or diabetes, or who smoke are also considered to be at risk. A universal approach to the prevention of CHD through diet and lifestyle is also described.

Coronary artery disease is the leading cause of death among black women in the United States. Black women also demonstrate a greater prevalence of coronary risk factors and a higher mortality after myocardial infarction than white women. To evaluate the clinical profile and outcome of black women in an urban-based cardiac rehabilitation program, 35 black women (aged 54 +/- 13 years) and 47 white women (aged 57 +/- 10 years) were prospectively studied. Black women had similar admitting diagnoses as white women, with recent myocardial infarction being the most common (37%). Coronary risk factors were more prevalent in black women than white women in the program: hypertension (71% vs 53%; p = 0.09) diabetes mellitus (46% vs 26%; p = 0.06), obesity (74% vs 49%; p < 0.05). Cholesterol and high-density lipoprotein levels were similarly elevated in black (251 +/- 53 mg/dl) and in white (248 +/- 52 mg/dl) women, whereas 34% of black and 21% of white women were active smokers. There was no significant difference in initial exercise capacity at program entry. Fewer black women (51%) completed the 12-week program than white women (64%), p = NS. Comparison of initial and follow-up exercise tests after 12 weeks of moderate to high-intensity dynamic exercise demonstrated significant and similar improvements in functional capacity in both black (4.2 +/- 1.6 vs 5.6 +/- 1.7 METs; p < 0.001) and white (4.8 +/- 2.2 vs 5.7 +/- 2.2 METs; p < 0.01) women. Among obese patients, only the white women lost weight.(ABSTRACT TRUNCATED AT 250 WORDS)

Ischemic nephropathy encompasses renal insufficiency due to 3 different diseases, namely renal artery stenosis, so-called benign nephrosclerosis, and renal cholesterol embolism. All 3 disease entities may lead to a progressive loss of renal excretory function. If a patient presents with renal failure of unknown origin, renal artery stenosis should be looked for by color-coded duplex scanning or arteriography. The clinical presentation of benign nephrosclerosis in caucasians has no typical clues. Usually, a renal biopsy identifies this renal disorder in a patient with long-standing hypertension, moderate proteinuria and renal insufficiency. Cholesterol embolism typically affects several arterial trees, and is induced by arteriography in patients with arteriosclerosis of the aorta. The best treatment for ischemic nephropathy due to renal artery stenosis [conservative, angioplasty, surgery] is unknown because appropriately controlled trials are lacking. Invasive therapy should be considered in patients with bilateral renal artery stenosis or stenosis of a single functioning kidney, particularly if the affected kidney is not contracted. Arguments in favor of invasive therapy include the progressive nature of renal artery stenosis and the poor outcome of dialysis patients with this diagnosis as underlying renal disease.

Turner syndrome is associated with insulin resistance, increased incidence of type II diabetes, and hypertension, all of which are cardiovascular risk factors. The purpose of this study was to evaluate the lipid profile of girls with untreated Turner syndrome, (aged 5 to 14 years; 68% 45,XO) and age-matched, normal girls. A total of 137 girls with Turner syndrome and 70 normal girls had lipid profile measurements, including cholesterol, high-density lipoprotein cholesterol, and triglycerides. Older girls with Turner syndrome (> 11.0 years) had increased cholesterol levels (p < 0.01), compared with control values (190 +/- 38 vs 165 +/- 26 mg/dl). Cholesterol levels were elevated in older subjects with Turner syndrome versus normal subjects, after adjustment for age, karyotype, and body mass index z score effects (p = 0.01). In the subjects with Turner syndrome but not the normal subjects, serum cholesterol values correlated with age, weight, and body mass index z score (p < 0.02). We conclude that adolescent girls with untreated Turner syndrome have significantly increased cholesterol levels, independent of age, body mass index z score, or karyotype, and that these precede any treatment with exogenous estrogen or growth hormone.

To enhance compliance to physician referral as well as dietary and other lifestyle recommendations given at blood cholesterol (BC) screening programs, we randomized Pawtucket Heart Health Program SCORE (screening, counseling, referral event) participants with elevated BC levels into one of four groups: usual care group; a participant intervention group (mailed reminder letter and refrigerator magnet); a physician intervention group (mailed packet to participant's physician including letter, National Cholesterol Education Program [NCEP] guidelines, and preaddressed postcard to mail to patient); and a group that received both interventions. Beginning four months after the screening, we surveyed study subjects by phone. The participant intervention increased recall of physician referral and dietary recommendations; however, neither intervention successfully improved compliance to referral or dietary and lifestyle recommendations. Overall, 58%, 67% and 34% of subjects reported complying to physician referral, dietary recommendations, and lifestyle recommendations, respectively. Referral compliance was associated with a longer time interval between screening and survey (relative risk [RR] = 1.3, 95% confidence interval [CI[ = 1.0, 1.7), possession of medical insurance that covered physician visits (RR = 2.1, 95% CI = 0.98, 4.4), and history of hypertension (RR = 2.6, 95% CI = 1.1, 5.8). Dietary compliance was positively associated with baseline BC levels > or = 240 mg/dL (RR = 3.3, 95% CI = 1.4, 7.3) and negatively associated with increasing age; each one year increase in age corresponded to a 3% decrease in compliance (RR = 0.97, 95% CI = 0.9. 1.0).(ABSTRACT TRUNCATED AT 250 WORDS)

The coronary arterial lesions seen by angiography in 1666 consecutive male patients were converted to a score by the standardized scoring system advocated by Gensini. The resulting score, which allowed the disease to be expressed as a continuous variable, was effectively utilized to see the correlations between the severity of coronary arterial disease (CAD) and individual risk factors/risk markers. Significant correlations were seen between severity and age (P < 0.001), with a very low coefficient of correlation of 0.0873. On univariate analysis, no correlation was found between CAD severity and diabetes, smoking, positive family history of CAD, hypertension and other lipid fractions. On multiple regression analysis, significant correlations were found between severity and LDL Cholesterol, family history and total cholesterol after adjusting for other factors. The R2 for all these risk factors was only 14.1%. It is concluded that, although strong associations exist between risk factors and the occurrence of CAD, the small quantitative association detected between the presence of risk factors and the severity of disease is weak.

To evaluate long-term benefits and risks of CyA therapy in renal transplantation, we analyzed the 10-year experience with all 59 patients who had received a first cadaveric renal graft until August 1983 and were immunosuppressed with CyA. We compared their actual graft survival with that of all 213 patients who had received a first cadaveric graft from 1967 until August 1983, but were immunosuppressed initially with azathioprine and prednisone (AzaP). For comparison of p-creatinine, proteinuria, blood pressure, lipids, uric acid and skin malignancies we evaluated the patients staying unchanged on initial therapy for 10 years (CyA = 12, AzaP = 53). RESULTS. (1) Actual graft survival at 10 years was 34% (20/59) with CyA and 27% (58/213) in AzaP treated patients (intention to treat) (P = .09 = ns). At 1 to 5 years, graft survival was 15% superior with CyA, but after 7 years the survival curve of the CyA-group has closely joined the chronic decline seen in the AzaP group. This behaviour could neither be explained by chronic CyA-nephrotoxicity nor by chronic rejection after switching from CyA to AzaP. (2) P-creatinine at 10 years was significantly (P < .03), but mildly elevated under CyA (130 +/- 52; AzaP = 109 +/- 65). (3) Proteinuria (g/d) at 10 years was not significantly different (CyA = 0.41 +/- 0.58, versus AzaP = 0.83 +/- 1.61). (4) Systolic blood pressure was higher at 10 years under CyA (152 +/- 19) than under AzaP (136 +/-) (P < .02), but diastolic pressure was not (89 +/- 10 versus 84 +/- 12; ns). Antihypertensive drug/patient was twice as high under CyA (1.25 versus 0.64 P < .02). (5) Cholesterol, triglyceride, HDL were not different. 75% of the CyA-patients were steroid free at 10 years, none of the AzaP-patients. (6) P-uric acid was not significantly different in both groups (494 +/- 192 vs 400 +/- 124), but 42% of CyA-patients were on uric acid lowering drug (given after at least one gout attack) as compared to 9% under AzaP (P < .006). (7) Seventeen percent of patients under CyA for 10 years had at least one skin cancer, not different from 15% of AzaP-patients. CONCLUSIONS. The main benefit of CyA was the better graft survival up to 5 years and the chance to stay free of steroids. The main risks of CyA were nephrotoxicity, hypertension and symptomatic hyperuricemia. No difference was found for hyperlipidemia and skin-malignancies.
