2 Giriş ve HedeflerBu sunum metabolik sendromun temel özelliklerini ve idaresini tartışıyor.Metabolik sendrom şu an neredeyse epidemik bir prevalansa sahip.Metabolik sendrom koroner,periferal vasküler ve CNS endotelyal hasarla sonuçlanır.Metabolik sendrom kesinlikle artmış CVD olayları ve ölüm riskiyle ilişkilidir.CVD risk faktör modifikasyonu metabolik sendromun kontrolünde anahtar role sahiptir.Metabolic syndrome is a cluster of clinical and biochemical abnormalities associated with the onset and progression of atherosclerotic cardiovascular disease (CVD). Adults with metabolic syndrome experience significantly greater mortality from coronary artery disease (CAD), vascular disease, stroke, and other causes in comparison with those who do not have the disorder. An enormous population is at risk, with important implications for public health. Comprehensive treatment strategies to modify CVD risk factors can ameliorate many of the pathophysiologic markers of metabolic syndrome and contribute to improved outcome.This presentation will discuss epidemiologic, clinical, and therapeutic issues relevant to metabolic syndrome, with the goal of improving early identification and appropriate treatment of this near-epidemic condition.Malik S, Wong ND, Franklin SS, et al.

3 Metabolik Sendrom: Genel Tanım Metabolik sendrom birbiriyle ilişkili klinik ve biyokimyasal bozuklukların bir bütünüdür.İçerdikleri:Abdominal obeziteYükselmiş trigliserid ve düşük HDL-C (atherojenik dislipidemi)Yükselmiş kan basıncıInsulin direnci, glukoz intoleransıyla birlikte veya değilProtrombotik ve proinflamatuar belirteçler (artmış CRP, fibrinojen, ve diğer koagulasyon faktörleri)Metabolic syndrome is a cluster of physical and biochemical derangements, including abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, insulin resistance, a prothrombotic state, and a proinflammatory state.1 Atherogenic dyslipidemia is a complex of lipid abnormalities—elevated triglycerides, low high-density lipoprotein cholesterol (HDL-C), and, often, a high concentration of small low-density lipoprotein (LDL) particles—that commonly occur together and can be considered a single target of therapy. Insulin resistance is considered by some investigators to be the prime underlying cause of metabolic syndrome, since elevated triglycerides and low HDL-C are characteristic lipid changes seen in patients with type 2 diabetes mellitus (DM).1,2 Signs of systemic inflammation, clinically assessed by C-reactive protein (CRP), and elevated concentrations of proteins involved in thrombosis, are also components of metabolic syndrome.1 As will be shown, specific criteria have been established by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), the World Health Organization (WHO), and the International Diabetes Federation (IDF).1.

Abdominal obesity is defined by NCEP ATP III only in terms of waist circumference, whereas the WHO criteria allow a definition by body mass index.2 In addition, NCEP ATP III criteria consider impaired glucose regulation as only one of an array of potential findings that can support the presence of metabolic syndrome. In contrast, WHO criteria require that insulin resistance be demonstrated before proceeding further with the evaluation for metabolic syndrome. Insulin resistance is demonstrated by the presence of impaired glucose tolerance, impaired fasting glucose, diabetes or, in patients with normal fasting glucose values, glucose uptake below the lowest quartile of the background population in the presence of hyperinsulinemia and euglycemia. The WHO classification may require special testing of glucose regulation that is beyond routine clinical evaluations.21. Grundy SM, Brewer HB, Cleeman JI, et al, for the Conference Participants.

For this reason, the IDF has adjusted the cutoff points of waist circumference as a diagnostic criterion of metabolic syndrome to reflect ethnic and racial variations in patterns of fat distribution. For some ethnic and regional groups, not listed on the slide, there are not yet sufficient data to establish specific criteria. Pending such data, the IDF recommends that the South Asian definitions be applied to ethnic South and Central Americans, and the European definitions to sub-Saharan Africans and to Eastern Mediterranean and Middle Eastern (Arab) populations.International Diabetes Foundation.

7 Metabolik Sendromun Amerikada yetişkinlerdeki yaş ve etnik kökene göre prevalansı. This analysis of NHANES III data incorporates ethnicity and gender, revealing dramatic differences between populations. Among white subjects, males and females displayed a similar prevalence of metabolic syndrome. Both African American and Mexican American women, however, demonstrated a higher proportion of metabolic syndrome compared with their male counterparts (African American women, 20.9%, versus 13.9% for men; Mexican American women, 27.2%, versus 20.8% for men). African American women had a prevalence of the disorder that was 57% higher than that of African American men, and Mexican American women demonstrated a 26% higher prevalence than Mexican American men.Park YW, Zhu S, Palaniappan L, Heshka S, Carnethon MR, Heymsfield SB.

It is particularly prevalent (>30%) in overweight adolescents (overweight defined as 95th percentile of body mass index [BMI] for age and sex). The best current estimates for adolescents suggest that more than 2 million have metabolic syndrome. These findings have important fiscal and public health implications.Duncan GE, Li SM, Zhou X-H.

According to the WHO criteria, however, insulin resistance must be present for the diagnosis of metabolic syndrome to be made. Numerous cardiovascular risk factors arise as a consequence of insulin resistance, many of which are core constituents of metabolic syndrome.Grundy SM, Brewer HB, Cleeman JI, et al, for the Conference Participants.

Even after adjustment for other known cardiovascular risk factors, including smoking status, blood pressure, serum lipids, ethnicity, and others, patients with higher levels of insulin resistance experienced significantly higher levels of cardiovascular pathology.Hanley AJG, Williams K, Stern MP, et al.

What may be clearly seen here, however, is that many of the cardiovascular risk factors that characterize metabolic syndrome are associated with insulin resistance. Increased fasting insulin levels as well as increased fasting glucose levels predict arterial stiffness, which in turn promotes hypertension, another known risk factor for CVD. Abnormal lipid levels characterized by low HDL-C, the presence of small, dense LDL particles, and elevated triglycerides are promoted by insensitivity to insulin, as normal lipoprotein metabolism becomes dysfunctional. Other consequences include hypercoagulation and impaired fibrinolysis. Enhanced lipid breakdown from insulin-resistant adipose cells results in increased availability of free fatty acids, and ultimately increased deposition of lipid in the arterial wall. This in turn leads to increases in vascular inflammation and the production of inflammatory markers.McFarlane SI, Banerji M, Sowers JR. Insulin resistance and cardiovascular disease.

13 WOSCOPS: CAD Riski Metabolik Sendrom Kriterlerinin Sayısıyla Artıyor Metabolik sendrom özellikerinin miktarı1234In the West of Scotland Coronary Protection Study (WOSCOPS), the presence of metabolic syndrome increased the risk for a CAD event. The risk increased as the number of metabolic syndrome features accumulated, and men with 4 or 5 features of the syndrome had a 3.7-fold increase in risk for CAD compared with men who had no feature of the syndrome (P<.0001). The inflammatory marker CRP enhanced the prognostic value of this information.Sattar N, Gaw A, Scherbakova O, et al.

Levels of CRP were assessed in these apparently healthy women, and their correlation with metabolic syndrome and cardiac events was evaluated. 24% of the initially healthy cohort had metabolic syndrome at study entry. There was a strong linear correlation between increasing levels of CRP and the number of components of metabolic syndrome that were present. While the presence of at least 3 components of metabolic syndrome predicted incident events, the incorporation of CRP levels above 3.0 mg/L added prognostic information at all levels of severity of the underlying metabolic syndrome. Finally, these findings were confirmed regardless of which definition of metabolic syndrome was used. Over 8 years of follow-up, cardiovascular event–free survival rates based on CRP levels above 3.0 mg/L were similar to survival rates based on having 3 or more characteristics of metabolic syndrome.Ridker PM, Buring JE, Cook NR, et al.

Based on 11 prospective studies encompassing over 11,000 subjects, DECODE used a modified WHO definition of metabolic syndrome, including hyperinsulinemia as a component, with a median follow-up of 8.8 years. Overall, 15.7% of men and 14.2% of women had metabolic syndrome. A meta-analysis of the association of metabolic syndrome with mortality in 7 study cohorts included in DECODE is shown above. Elevated risk for CVD and all-cause mortality was seen consistently in all nondiabetic subjects in whom the diagnosis of metabolic syndrome was made, and the association with CVD mortality was especially pronounced in cases in which hyperinsulinemia was documented in conjunction with at least 2 additional criteria. During the course of the study, 432 of 1119 recorded deaths were caused by CVD. The overall hazard ratios for all-cause and CVD mortality in persons with metabolic syndrome compared with persons without it were 1.44 (95% confidence interval [CI], ) and 2.26 (95% CI, ) in men and 1.38 (95% CI, ) and 2.78 (95% CI, ) in women after adjustment for age, blood cholesterol levels, and smoking.Hu G, Qiao Q, Tuomilehto J, et al, for the DECODE Study Group.

16 KV Sağlık Seviyeleriyle, Metabolik Sendrom ve CVD Mortalitesi Stres testinde alınan en yüksek oksijen seviyeleriThe Aerobics Center Longitudinal Study evaluated the relationship between cardiorespiratory fitness and mortality in healthy men and men with metabolic syndrome. Men with and without metabolic syndrome underwent a maximal treadmill exercise test and were classified as fit or unfit by quintiles based on maximum oxygen uptake during the test. The sample included 19,223 men, aged 20 to 83 years, entered into the study between 1979 and 1996, representing 196,298 subject-years of follow-up. All-cause and cardiovascular death rates were found to be greater among men with metabolic syndrome compared with their healthy counterparts. In both groups, however, death rates were markedly reduced among men with better fitness.1A prospective study investigating the relationship between cardiovascular fitness and risk for metabolic syndrome found them to be clearly inversely related in both men and women. Reductions in risk for metabolic syndrome among men in the upper and middle tertiles of cardiorespiratory fitness compared with that of men in the lower tertile were 53% and 26%, respectively; the corresponding risk reductions among women were 63% and 20%.21.

Increments of BMI (normal to overweight to obese) were not associated with 3-year risk of death (hazard ratio [HR] 0.92, 95% CI 0.59 to 1.51) or major adverse cardiovascular events (HR 0.95, 95% CI 0.71 to 1.27), but metabolic status (normal to metabolic syndrome to DM) was associated with a doubling of the risk for death (HR 2.01, 95% CI 1.26 to 3.20) and major adverse cardiovascular events (HR 1.88, 95% CI 1.38 to 2.57).1 This finding suggests that the risk factors that constitute metabolic syndrome interact to worsen prognosis more than the presence of a single risk factor, such as obesity, by itself. In an analysis of 4-year data from the same study, metabolic syndrome was associated with a significantly higher risk of cardiovascular events in comparison with women without metabolic syndrome if significant CAD was present at baseline (HR 4.93, 95% CI 1.02 to 23.76); metabolic syndrome without angiographically significant CAD was not associated with increased 4-year cardiovascular risk (HR 1.41, 95% CI 0.32 to 6.32).2 This suggests that it may be necessary to investigate different strategies to ameliorate the risk associated with metabolic syndrome in patients with and without angiographically significant CAD.1.

Saturated fats should be restricted to less than 7% of the total caloric intake, and less than 200 mg of cholesterol should be included in the daily diet. In addition, the reduction of LDL-C may be augmented by the addition of 2 grams per day of plant stanols or sterols, and increases of viscous, or soluble, fiber in the daily diet to 10 to 25 grams. Total caloric intake should be adjusted to attain and maintain a desirable body weight and prevent weight gain. Finally, sufficient moderate exercise should be included in the daily routine to expend at least 200 kcal per day. Approximately 45 minutes of walking at 3 mph or 25 to 30 minutes of jogging at 5 mph is an example of moderate exercise expending 200 kcal.

22 Metabolik Sendromun İlaç Tedavisi (NCEP ATP III) Hastanın riskini saptayınLDL-C amacına ulaşınAtherojenic dislipidemi’yi düzeltinNonHDL-C amacına ulaşınYüksek trigliserid’li hastalar için ikinci hedef (≥200 mg/dL); non–HDL-C hedef = LDL-C hedef + 30 mg/dLDüşük HDL-C seviyesini yükseltinThe first priority in pharmacologic treatment of metabolic syndrome is to achieve LDL-C goals, which depend on the patient’s level of risk for CAD (see the next slide). Pharmacologic treatment should also be directed at correction of overall atherogenic dyslipidemia. Non–HDL-C is a secondary target of therapy for patients with high triglyceride levels (200 mg/dL). Since non–HDL-C comprises LDL-C plus very-low-density lipoprotein cholesterol (VLDL-C), and a VLDL-C level of <30 mg/dL is considered normal, the NCEP ATP III suggests that an appropriate non–HDL-C goal is one 30 mg/dL higher than the LDL-C goal. For example, if the LDL-C goal is <130 mg/dL, the non–HDL-C goal will be <160 mg/dL. Consideration should be given to raising HDL-C, but HDL-C target levels have not been determined.Third Report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III) final report.

These guidelines suggest that subgroups of patients at high or very high risk for cardiovascular events, such as those with metabolic syndrome, may benefit from very aggressive lowering of LDL-cholesterol to levels <70 mg/dL. Such patients may still have lifestyle-related risk factors that are appropriate for aspects of TLC regardless of the LDL-C level. Concurrent TLC and pharmacologic therapy may modify these risk factors at the same time that elevated LDL-C—the primary target of cholesterol-lowering therapy—is being addressed.Grundy SM, Cleeman JI, Merz CN, et al.

Of these patients, 43% met modified NCEP ATP III criteria for metabolic syndrome (obesity evaluated by BMI rather than waist circumference). As shown in this slide, a subsequent subanalysis of the MERCURY results showed that achievement of NCEP ATP III LDL-C treatment goals with statin therapy was comparable between patients with and without metabolic syndrome.Stender S, Schuster J, Barter P, Watkins C, Kallend D; on behalf of the MERCURY Study Group.

28 RIO-LIPIDS Vaka BulmaDislipidemili obez hastalar için selektif CB1-reseptor blokeri rimonabant tedavisinin rastgele, kontrollü çalışmasıAna hedef:Rimonabant tedavisinin kilo kaybı ve lipid seviyeleri üzerine olan sonuçlarını hesaplaTedavi araları ve hedefler:1036 dislipidemik hasta BMI (27-40 kg/m2)5 mg/d veya 20 mg/d rimonabant veya placebo 1 yıl boyuncaHastalardan aldıkları kaloriyi 600 kalori/d düşürmeleri istendi.Ana son noktalar:1. yılda, kilo kaybı 5% ve ≥10% ve lipid profilleri değiştiEvidence is mounting that obesity, an important cardiovascular risk factor that is a component of metabolic syndrome, as well as smoking, another major risk factor, may be managed with a new class of drugs, selective CB1 blockers. The CB1 receptor subtype of the endocannabinoid system (ES) has a central and peripheral role in metabolism and is implicated in the regulation of eating and fat deposition and in tobacco dependency. The RIO (Rimonabant in Obesity) LIPIDS trial was designed to compare the effects of treatment with two doses of a new cannabinoid receptor antagonist, rimonabant, versus placebo in 1036 obese patients with dyslipidemia. Patients were instructed to reduce their intake by 600 calories per day and received general nutritional counseling on caloric reduction without a specific diet to follow. They were randomized to 5 mg/d or 20 mg/d of rimonabant or placebo for 1 year. Treatment end points at 1 year were a weight loss of 5% of body weight and 10% of body weight and a change in the lipid profile.Despres J-P. Rimonabant in obesity.

29 RIO-LIPIDS Vaka Sonuçları Kilo kaybı 5%P<.001 for high-dose vs placebo.Kilo kaybı 10%P<.001 for high-dose vs placebo.At 1 year, weight losses of more than 5% and 10% per year were significantly greater in patients taking rimonabant versus placebo. Almost 90% of patients on the treatment lost 5% of their total body weight and 44% lost 10%. Patients on high-dose rimonabant lost an average of 20 pounds and 3 inches from their waistline and reported feeling less hungry.High-density lipoprotein cholesterol (HDL-C) levels unexpectedly increased in all 3 groups from baseline to 52 weeks; however, results in rimonabant-treated patients were significantly different from those in placebo patients, with HDL-C levels rising 23% in the 20-mg treatment group. Triglyceride levels decreased 15% and C-reactive protein decreased 27% in the high-dose group as well. There was also a reduction in the proportion of small, dense LDL-C particles.Change in metabolic syndrome status was also shown to improve dramatically. Of the group randomized to rimonabant 20 mg/d treatment, 42.2% had metabolic syndrome as defined by NCEP ATP III. After treatment with rimonabant 20 mg/d, this was reduced by more than half at 19.6% (P<.001).The results of the RIO-LIPIDS trial suggest a potential role of the ES and of CB1 antagonists in the treatment and/or prevention of obesity, metabolic syndrome, and tobacco use.Despres J-P.

The intensive lifestyle program was designed to achieve loss of ≥7% of body weight with a carefully controlled diet and moderate physical exercise for ≥150 minutes weekly.Intense lifestyle change, among patients who did not meet criteria for metabolic syndrome at baseline, was effective in limiting the incidence of all elements of the syndrome except for low levels of HDL-C. Metformin, however, in the same group, was successful compared with placebo only in the categories of obesity/overweight measured by waist circumference and fasting plasma glucose levels.Among patients who had already been diagnosed with metabolic syndrome at baseline, both metformin and intensive lifestyle change successfully reduced the prevalence of the metabolic syndrome characteristics of overweight/obesity measured by waist circumference, low HDL-C levels, and elevated fasting plasma glucose levels. Intensive lifestyle change also significantly lowered the prevalence of elevated blood pressure and triglycerides.Orchard T, Temprosa M, Goldberg R, et al, for the Diabetes Prevention Research Group.

33 AHA/NHLBI Klinik Yönetim: Hayat Tarzı Risk Faktörleri Metabolik Sendrom tanısı için Modifiye NCEP ATP III kriterleri: AKŞ sınırı 100 mg/d’ye düşürüldü.Hayat Tarzı Faktörlerinin YönetimiAbdominal obesite: Kilo verme 7% ile 10% a kadar.Mümkünse hedef BMI ve bel çevresine ulaşmak için daha fazla.Fiziksel İnaktivite: Düzenli orta zorlukta aerobik aktivite.Atherojenik diet: Doymuş yağ,kolestrol alımının azaltılmasıIn October 2005, the American Heart Association (AHA) and National Heart, Lung, and Blood Institute (NHLBI) published a Scientific Statement on the diagnosis and management of metabolic syndrome. This will no doubt be an authoritative source of guidance in this area for health care professionals.The AHA/NHLBI statement adopts the diagnostic criteria of the NCEP ATP III (see Slide 4) with slight modifications. The threshold for IFG is reduced from 110 to 100 mg/dL. In addition, any of the criteria of elevated triglycerides, low HDL-C, and elevated blood pressure and fasting glucose is met if the patient is receiving drug treatment for the abnormality in question.Modification of lifestyle-related risk factors is the first line of management. Abdominal obesity is targeted by weight loss and maintenance through modifications of diet and physical activity. A slow loss of about 7% to 10% of body weight is the initial goal, with further reduction thereafter, if possible, to target BMI and waist circumference. Moderate-intensity aerobic activity totaling at least 30 to 60 minutes at least 5 days a week is recommended. Resistance training 2 days a week is encouraged. In the diet, total fat should be limited to 25% to 35% of total calories, and saturated fat to less than 7%; trans fats should also be restricted. Consumption of simple sugars should be limited as well.Grundy SM, Cleeman JI, Daniels SR, et al. Diagnosis and management of the metabolic syndrome.

For patients with triglyceride levels of 200 mg/dL or higher after maximal LDL-C lowering, non–HDL-C can be the target of therapy. Elevated total Apo B is an alternative target, but accurate measurement of non–HDL-C is more readily available. Non-HDL-C goals, shown in the slide, are 30 mg/dL higher than the LDL-C goals determined according to the patient’s level of cardiovascular risk. Risk level is determined as follows:• Very high risk: high likelihood of major CVD events in the next few years, eg, recent acute coronary syndrome or established CAD plus multiple major risk factors (especially diabetes), poorly controlled severe risk factors (especially cigarette smoking), or metabolic syndrome• High risk: atherosclerotic CVD, diabetes, or >20% 10-year CAD risk• Moderately high risk: 10% to 20% 10-year CAD risk; factors that may favor the optional non–HDL-C goal of <130 mg/dL include advanced subclinical atherosclerotic disease (eg, carotid intima-media thickness >75th percentile) as well as the same supplementary factors that confer very high risk (above)• Moderate risk: 2+ major risk factors and <10% 10-year risk• Lower risk: 0 or 1 major risk factor and <10% 10-year riskNo specific target level of HDL-C is set. To raise HDL-C levels, lifestyle therapies should first be maximized. If HDL-C is undesirably low after maximal LDL-C lowering, a fibrate or niacin may be considered.Grundy SM, Cleeman JI, Daniels SR, et al. Diagnosis and management of the metabolic syndrome. An American Heart Association/National Heart, Lung, and Blood Institute Scientific Statement.

For patients with diabetes or chronic kidney disease, the goal is BP below 130/80 mm Hg. Even if overt hypertension is not present, reduce BP as far as possible through lifestyle changes. For patients with IFG (100 mg/dL*), emphasize weight reduction and increased physical activity to delay progression to diabetes. For patients with diabetes, treat with lifestyle changes and pharmacotherapy as necessary to achieve an HbA1c level below 7.0%. For high-risk patients with metabolic syndrome, low-dose aspirin therapy is recommended to reduce the prothrombotic state associated with the syndrome, and it may also be considered for patients at moderately high risk. Clopidogrel can be considered for patients with atherosclerotic CVD who cannot tolerate aspirin. No specific treatment is recommended for the proinflammatory state of metabolic syndrome, which may be ameliorated by lifestyle therapies.*The NCEP ATP III 2001 criteria used 110 mg/dL as the definition of IFG. This was changed in 2004 to 100 mg/dL to agree with the American Diabetes Association’s revised definition of IFG.Grundy SM, Cleeman JI, Daniels SR, et al.

It is a major public health problem in the United States, affecting approximately one quarter of all adults. The components of metabolic syndrome, which include abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, insulin resistance, and a proinflammatory, prothrombotic state, work synergistically to increase cardiovascular risk to a level beyond what would be expected from the simple accumulation of separate risk factors. Although not required for the diagnosis of metabolic syndrome by NCEP ATP III criteria, insulin resistance is present in most patients with metabolic syndrome and is associated with many cardiovascular risk factors. TLCs, including improved diet and increased physical activity, are the cornerstone of therapy for metabolic syndrome, and it is patients with metabolic syndrome who derive the greatest benefit from such measures. However, patients with metabolic syndrome can also benefit from pharmacologic lipid-lowering therapy, including statins. Promising developments for the management of metabolic syndrome include the development of endocannabinoid receptor blockers, a class of agents that show promise for the treatment of the obesity associated with metabolic syndrome.
