Hyperlipidemia is now established as a major risk factor for causation of coronary heart disease (CHD) in adults; however, there is much debate on the level of coronary risk at which lipid-lowering drugs should be used. These issues of possible harm or lack of benefit from long-term use of lipid-lowering therapy, and cost effectiveness, are also pertinent in the pediatric setting. Evidence from several countries indicates that children have an increasing prevalence of obesity, hyperlipidemia and type 2 diabetes mellitus. Children who have high serum lipids 'track' these increased levels into adulthood. In some countries there is a trend to screen children for hypercholesterolemia. Family history itself is a poor discriminator in determining which children need to be screened and treated. Estimation of apolipoprotein B and/or apolipoprotein E genotype can improve prediction. Measuring high density lipoprotein cholesterol also helps, but obesity appears to be the best marker for screening children at high risk. These considerations should not cloud the need for case finding and treatment of children with genetic disorders. Low fat diets have been shown to be well tolerated and effective in children; however, there are no major long-term studies demonstrating harm or benefit in those on lipid-lowering drugs. Nevertheless, concerns regarding the psychological effect and the theoretical metabolic effects of long-term lipid lowering remain. Lipid-lowering drugs should be generally restricted to children with genetic disorders of lipid metabolism. Children with diabetes mellitus, hypertension or nonlipid-related inherited disorders leading to premature CHD in adults should be treated with diet, and with lipid-lowering drugs when they reach adulthood. Children with secondary hyperlipidemia should be assessed individually. A number of drugs and nutriceuticals are available for use in children, but only a few drugs are licensed for use in children.

Ischaemic heart disease is one of the leading causes of cardiovascular morbidity and mortality. Because most factors leading to cardiovascular disease have a silent course, early screening is needed for prevention and for halting disease progression. In our centre, a programme was implemented in apparently healthy subjects for the early diagnosis and treatment of factors known to increment the risk of developing cardiovascular and metabolic disease. We present data from the first 153 individuals evaluated. The incidence of modifiable risk factors in our healthy population was as follows: overweight 33% (BMI: 25-30 kg/m(2)), obesity 45% (BMI >30 kg/m(2)), sedentarism 84%, arterial hypertension 15% (>140/90 mm Hg), hyperinsulinaemia 50%, glucose intolerance 14% (>160 mg/dl 120 min after 75 g glucose load), type 2 diabetes mellitus 5%, hypercholesterolaemia 50%, hypertriglyceridaemia 28%, and salt sensitivity 25%. Clustering of three or more cardiovascular risk factors was observed in 59% of the apparently healthy subjects. Obesity was associated with greater clustering of risk factors. The cardiovascular dysmetabolic syndrome was present in 72% of the obese individuals. These findings revealed a very high prevalence of cardiovascular risk factors in apparently healthy Hispanics. Even though these individuals were clinically asymptomatic, they are at increased risk for developing cardiovascular disease and type 2 diabetes mellitus. Mechanisms for the early detection and correction of modifiable risk factors in the healthy population must be implemented. Only through prevention will a reduction in the incidence of cardiovascular atherosclerotic disease and of type 2 diabetes mellitus be achieved.

Over the last few years, there has been a considerable reduction in the mortality and morbidity associated with HIV patients, due to the use of protease inhibitors which have led to a true revolution in the treatment of this infection. A new problem has arisen with the increased life expectancy: the onset of a plurimetabolic syndrome characterized by hypertriglyceridaemia, hypercholesterolaemia and hyperglycaemia; in addition to anomalies in composition and distribution of body fat (central obesity and loss of peripheral fat) due to the associated lipodystrophy. As a result of the metabolic alterations, there is an increase in the risk of cardiovascular disease. Hyperglycaemia is the result of insulin resistance and is detected in between 13.6% and 46% of patients, possibly leading to type 2 diabetes (diagnosed in between 2.4% and 7% of the patients). These alterations have been documented as potentially related with the use of protease inhibitors and other drugs used in the handling of HIV patients. The appropriate treatment of altered metabolism of carbohydrate requires: 1) a customized dietary approach depending on individual BMI and lipid alterations; 2) a physical exercise programme; 3) the use of insulin sensitization drugs: metformin and thiazolidinediones and, where the therapeutic goals are not achieved or there is a contraindication for oral hypoglycaemic drugs; 4) insulin therapy with regimens similar to other diabetic patients.

HIGH CARDIOVASCULAR RISK: The clinical and metabolic anomalies observed in patients with type 2 diabetes are associated with high risk of cardiovascular disease (particularly coronary heart disease), which is responsible for 75% of all deaths in diabetic patients. CLASSICAL RISK FACTORS: Several large-scale surveys have demonstrated the role of classic risk factors such as hypercholesterolemia, smoking and hypertension in the development of ischemic heart disease compared with the general population. OTHER RISK FACTORS: Other risk factors in the diabetic patient include risk associated with the metabolic anomalies (blood glucose levels, insulin resistance) as well as to left ventricular hypertrophy and microalbuminuria, which are often found together in hypertensive diabetics. INTERNATIONAL GUIDELINES: The importance of these risks has led several organizations to issue guidelines, particularly regarding the need for stricter blood pressure control. Regular screening for microalbuminuria and renal dysfunction (creatinine clearance) is also recommended, as well as more rigorous objectives for lipid levels.

Patients with combined dyslipidemia are at greatly increased coronary heart disease (CHD) risk. The threat of rhabdomyolysis with dual pharmacologic treatment (hepatic hydroxymethyl glutaryl coenzyme A [HMG-CoA] reductase inhibitors plus fibric acid derivatives) has tended to limit therapy in patients with combined dyslipidemia to a choice of one or the other drug. Judgment of the potential benefits of either agent has rarely taken into account their effect on the postprandial accumulation of highly atherogenic, triglyceride (TG)-rich, remnant lipoprotein particles (RLPs). Because this information could be of substantial clinical relevance, we addressed this question in patients with type 2 diabetes and combined dyslipidemia by comparing the effects of gemfibrozil versus HMG-CoA reductase inhibitors (statins) on both fasting and postprandial lipid and lipoprotein concentrations. For this purpose, 22 patients with type 2 diabetes and combined dyslipidemia were randomized to treatment with either a statin or gemfibrozil for 3 months. Glycemic control was similar in both groups at baseline and did not change in response to treatment. Baseline lipid and lipoprotein concentrations were also similar in the 2 treatment groups, but the responses to therapy were quite different. Statin-treated patients had a statistically significant decrease in low-density lipoprotein (LDL) cholesterol concentration (156 mg/dL to 96 mg/dL, P <.001), whereas there was no change in patients treated with gemfibrozil. In contrast, there was a statistically significant decrease (P <.05) in plasma TG concentrations (116 mg/dL) in gemfibrozil-treated individuals, without any change in subjects treated with statins. However, the decrease in total integrated postprandial plasma RLP response measured hourly from 8 AM to 4 PM was not different in patients treated with either gemfibrozil (-43%) or statins (-34%). These results indicate that statin treatment, in addition to its beneficial effect on hypercholesterolemia, was as effective as gemfibrozil in reducing postprandial accumulation of triglyceride-rich, atherogenic RLPs in patients with type 2 diabetes and combined dyslipidemia. As such, the clinical utility of statin monotherapy in the treatment of combined dyslipidemia may have been underestimated.

Insulin resistant metabolic syndrome is a major clinical disorder including hyperlipidaemia, hypertension, impaired glucose tolerance and/or type 2 diabetes and central obesity, which are well established cardiovascular risk factors. We report the case of a 61-year-old woman who developed severe hypercholesterolaemia and hypertriglyceridaemia after liver transplantation. In her forties she had hypertension, mixed hyperlipidaemia, mild hyperglycaemia and moderate abdominal obesity, suggesting the presence of the metabolic syndrome. She had liver enzyme elevation and severe steatosis and hepatomegaly at ultrasonography. At age 52, cryptogenic liver cirrhosis was diagnosed and rapidly progressing liver failure developed. In 1992 she underwent liver transplantation. Seven years after transplant the patient had abdominal obesity, high blood pressure, marked hypercholesterolaemia, hypertriglyceridaemia and moderate elevation of alanine aminotransferase. She also had impaired glucose tolerance and markedly increased basal and post-glucose load plasma insulin levels. Steatohepatitis was demonstrated by serial liver biopsies. This is the first case that reports the recurrence of the metabolic syndrome following liver transplantation. We postulate that metabolic syndrome may have promoted fatty liver and subsequent progression to end stage liver disease. We also stress the need for careful management of the metabolic syndrome in order to decrease the long-term risk for cardiovascular disease.

Maori and other indigenous peoples experience a high prevalence of type 2 diabetes. A pivotal question is how primary and secondary preventative initiatives might be more effectively targeted to embrace those who are at highest risk of developing diabetes and its complications. This paper proposes that, in the case of Maori, as a high-risk population, conventional approaches are insufficient, and that increased consideration needs to be given to how the settings in which health education and services are offered may influence diabetes prevention and earlier diagnosis. Traditionally, the hub of Maori culture and everyday life is the marae, a place where Maori identity, values and cultural practices are affirmed within an over-arching spiritual dimension. We have investigated the potential utility of an urban marae and its member network as a setting for a lifestyle programme focused around diabetes prevention. The research included a cross sectional survey of behavioural and metabolic risk factors for type 2 diabetes and qualitative data collection as part of a formative and process evaluation of a lifestyle programme established at the marae and connected venues. The programme attracted 436 participants. The majority knew little about diabetes, had low levels of vigorous activity and high intakes of fatty foods. A family history of diabetes was present in >40% of participants. Undiagnosed diabetes, high blood pressure, hypercholesterolaemia, obesity, smoking and self-reported excessive alcohol consumption were common. The advent of diabetes education, a healthy lifestyle support programme, and exercise sessions at the marae and connected venues served as the impetus for the marae community to take over the running of their own health promotion programme, including a declaration of their marae as a 'smoke-free' venue. It is proposed that marae can be useful settings for lifestyle programmes aimed at controlling the diabetes and obesity epidemic in New Zealand.

A total of 5 randomized, double-blind trials in patients with hypercholesterolemia were prospectively designed to allow pooling of plasma lipid data after 12 weeks of treatment. The purpose was (1) to compare rosuvastatin 5 and 10 mg with atorvastatin 10 mg (data from 3 of the 5 trials); (2) to compare rosuvastatin 5 and 10 mg with simvastatin 20 mg and pravastatin 20 mg (data from 2 of the 5 trials); and (3) to summarize overall efficacy and subset analyses of rosuvastatin data from all 5 trials. Rosuvastatin 5 mg (n = 390) and 10 mg (n = 389) reduced low-density lipoprotein (LDL) cholesterol significantly more than did atorvastatin 10 mg (n = 393) (41.9% and 46.7% vs 36.4%, both p <0.001). Treatment with rosuvastatin 5 mg (n = 240) and 10 mg (n = 226) also resulted in significantly greater reductions in LDL cholesterol compared with both simvastatin 20 mg (n = 249) and pravastatin 20 mg (n = 252) (40.6% and 48.1% vs 27.1% and 35.7%, all p <0.001). Significant differences favoring rosuvastatin 10 mg were also observed for total cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL cholesterol, apolipoprotein (apo) B, and apo A-I versus atorvastatin 10 mg, and for total cholesterol, HDL cholesterol, triglycerides, non-HDL cholesterol, and apo B versus simvastatin 20 mg and pravastatin 20 mg. Analyses of all the rosuvastatin 10 mg data (n = 615) from the 5 trials in subgroups defined by age > or =65 years, female sex, postmenopausal status, hypertension, atherosclerosis, type 2 diabetes, and obesity showed that rosuvastatin had consistent efficacy across patient subgroups.

Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS). Increased plasma levels of ADMA may indicate endothelial dysfunction and increased risk of angiopathy. The relation of ADMA to diabetes, glycemic control, and renal function, especially early diabetic hyperfiltration, remains unknown. We tried to evaluate whether there is an association between ADMA and glycosylated hemoglobin (GHbA(1c)) on the one hand and glomerular filtration rate (GFR) on the other hand in diabetic subjects with normal or slightly increased GFR. We also studied whether plasma ADMA is associated with some risk factors of vasculopathy (hypercholesterolemia and hypertension). The study subjects consisted of 86 patients with type 2 diabetes and 65 control subjects. Plasma ADMA levels were measured by high-pressure liquid chromatography as o-pthalaldehyde (OPA) derivatives and GFR was determined by the plasma clearance of chromium 51-EDTA. The diabetic patients had lower plasma ADMA levels than the nondiabetic control subjects (0.29 +/- 0.15 v 0.34 +/- 0.16 micromol/L, P <.03). In the diabetic subjects, plasma ADMA concentrations were inversely correlated with GHbA(1c) (R = -0.28, P =.01). In a multivariate linear model, significant predictors of ADMA were GFR (R = -0.32, P =.008) in diabetic subjects and GHbA(1c) (R = -0.19, P =.03) and GFR (R = -0.19, P =.02) in all subjects. Plasma ADMA was not associated with risk factors of vasculopathy. We conclude that diabetic patients with a normal or slightly increased GFR have lower circulating ADMA concentrations than nondiabetic control subjects. In type 2 diabetic patients high GFR and poor glycemic control were related to low plasma ADMA concentrations.

Fifty consecutive younger patients (< or = 40 years) with coronary artery disease, who underwent coronary angiography in National Institute of Cardiovascular Diseases were evaluated clinically and coronary risk factors were analyzed and compared with those of fifty older patients with coronary artery disease. Mean age of younger and older patients were 37.31 and 54.58 years respectively and myocardial infarction was the most common presenting complain in both the groups. Smoking and family history of premature coronary artery disease were more common in younger patients but the older patients were more diabetic and hypertensive. Central obesity and dyslipidemia did not vary between the two groups. Fifty percent of younger patients had one or two modifiable risk factors where sixty four percent of older patients had three or more modifiable risk factors. Forty four percent younger patients had hypercholesterolemia but a majority of patients had either isolated hypertriglyciredemia or decrease high density lipoprotein cholesterol or both with normal total cholesterol level but the total cholesterol and high density lipoprotein cholesterol index were more than 4.5. Younger patients had more number of normal coronary or single vessel diseases but older group had more number of triple vessel diseases. So the higher incidence of non-insulin dependent diabetes mellitus with central obesity suggesting insulin resistance along with unique profile of dyslipidemia, higher incidence of smoking and familial predisposition of premature coronary artery disease may be responsible for higher incidence of coronary artery disease at a premature younger age in this population.
