3 07/09/13 Research in 2004 forecast Indian diabetic population to reach ~80 Mn by 2030… 2004 Diabetes Care publication predicted Indian diabetic population will reach 80 million by 2030, but….. *Number in the adult population (20 years of age). Wild S et al. Diabetes Care. 2004;27:

4 …however, it has breached 60 Mn in 2011 itself
07/09/13 …however, it has breached 60 Mn in 2011 itself Diabetic population in India: ICMR INDIAB study 2011 62.4 million people with diabetes 77.2 million people with pre-diabetes RM Anjana et. al in Diabetologia in 2011 report that it had already reached to 62.4 million in 2011 only, as per ICMR INDIAB data. Moreover, Diabetics are spread out across the country irrespective of Urban or Rural population. RM Anjana et. al. Diabetologia (2011) 54:3022–3027 DOI /s

5 Globally, dyslipidemia is a widespread condition in diabetics
07/09/13 Globally, dyslipidemia is a widespread condition in diabetics Selby et al report in Am J Manag Care 2004 that 3 out of 4 diabetics are also dyslipidemic Conclusion : Every 3 out of 4 diabetic suffers from dyslipidemia Selby JV et al. Am J Manag Care. 2004;10(part 2):

6 Only a minority (<18%) of patients with T2DM achieve ABC goals
The “ABCs” of optimal CV health in diabetes are: Most T2DM patients fail to achieve these targets: In a study of 5426 diabetic patients (who were on treatment) in USA from 2008 to 2009, only 17.3% could achieve all the 3 ABC targets A HbA1c < 7.0% B BP < 130/80 mm Hg C LDL-C < 100 mg/dL So novel therapeutic options are required for optimal management So current management options inadequate & So novel therapeutic options are required for optimal management of T2DM Vouri Sm etal. Manag Care Pharm. 2011;17(4):304-12

7 But in India, almost 9 out of 10 diabetics have dyslipidemia
07/09/13 But in India, almost 9 out of 10 diabetics have dyslipidemia This suggests that there are >55 millions patients of diabetic dyslipidemia in India Prevalence of Dyslipidemia (%) in Male T2 DM Prevalence of Dyslipidemia (%) in Female T2DM 85.5% 85.5 % 97.8 % RM Parikh in Diabetes and Metabolic Syndrome: Clinical Research and Reviews report that in India, Prevalence of dyslipidemia in diabetic population is very high(9 out of 10), almost all diabetics (specially females) have dyslipidemia. 90% of 62 Mn T2DM patients is >55 Mn. Pre-diabetics also have insulin-resistance leading to dyslipidemia – that means another 70 million dyslipidemics. Dyslipidemia Dyslipidemia RM Parikh et al.

8 20483_85 07/09/13 Lifestyle and genetic factors also contribute to higher incidence of dyslipidemia in Indians Diet Dyslipidemic profile - seen in vegetarians* Indian diets rich in carbohydrate and low in Omega-3 PUFA- exacerbates hyper-triglyceridemia.* Physical Activity Asian Indians-more physically inactive: May be due to fast economic development in recent years** Genetic Factors Abnormal variants of ApoC 3 and ApoE 3 genes common in India^ Indians have more abdominal adiposity* Thrifty gene to blame too Diet: Dyslipidemic profile is commonly seen in the vegetarians* Indian diets rich in carbohydrate and low in Omega-3 poly-unsaturated fatty acids which exacerbates hyper-triglyceridemia.* Physical Activity: Asian Indians are more physically inactive as compared to many other ethnic groups** Genetic Factors: Abnormal variants of Apo C3(cause Lipoprotein lipase inhibition) and ApoE3 (formation of VLDL) genes are common in India which can lead to more dyslipidemia^ Indians have excessive body fat and more abdominal adiposity which is harmful even if BMI is under control* Indians more prone to Syndrome X - The "Starvation Gene Theory" India suffered droughts for hundreds of years. Fats and carbohydrates provide energy to the body. So our genes adapted to survive long periods of drought by consuming fats and carbohydrates slowly to make them last longer Now our bodies get adequate supplies of food, but these genes are still in action as they take a long time to adapt, so our food continues to be metabolised slowly resulting in the dysfunctional biochemical profile that constitutes Syndrome X. . *Misra & Vikram ,Nutrition May;20(5):482-91 ** Talwar & Misra,J Assoc Physicians India 2002;50:1521 ^Misra et al, J Assoc Physicians India 2004;52:137-42

9 Besides, body composition of Asian Indians makes them more vulnerable
07/09/13 Besides, body composition of Asian Indians makes them more vulnerable Shorter height* Lower body mass index* Excess body fat in relation to body mass index † Abdominal adiposity High waist-to-hip ratio ‡ Normal waist circumference*§ High intra-abdominal fat* Truncal adiposity Thick subscapular skinfold thickness* More abdominal subcutaneous fat*II Less lean body mass*¶ Misra in Nutrition 2004 points out that Asian Indians have a high prevalence of insulin resistance syndrome that may underlie their greater than normal tendency to develop diabetes mellitus and early atherosclerosis. Important reasons could be their excess body fat and adverse body fat patterning including abdominal adiposity even when the body mass index is within the currently defined normal limits. Some of these features have been reported at birth and childhood. Whether Asian Indians also have tendency to develop insulin resistance de novo, independent of total or regional adiposity, needs further investigation. Underlying genetic tendency or early-life adverse events may contribute to such a phenotype, but lifestyle factors alone or modulated by inherited factors appear to play an important role because obesity and dyslipidemia become worse with urbanization and migration. Systemic stress may contribute to insulin resistance syndrome in the intra-country and inter-country migrant Asian Indians. High prevalence of excess body fat, adverse body fat patterning, hypertriglyceridemia, and insulin resistance beginning at a young age have been consistently recorded in Asian Indians irrespective of their geographic locations. These data suggest that primary prevention strategies should be initiated early in this ethnic group. * As compared with whites or blacks. † High body fat per unit of body mass index. II As estimated by skinfold thickness measurements or imaging techniques. ¶ Particularly in the lower extremities. ‡ This may be due to less lean mass at the hips resulting in a smaller hip circumference. § Average value of waist circumference usually does not exceed the currently accepted cutoff values for abdominal obesity. *Misra, Nutrition May;20(5):482-91

10 Relative Serum Concentrations
07/09/13 Indian dyslipidemia is different from its Western counterpart in terms of lipid parameters Comparison of Indian vs. Western Dyslipidemia Lipid Relative Serum Concentrations TC Similar LDL-C Similar (129 Vs 124 mg/dL) sd-LDL-C TG Higher (174.5 Vs 146 mg/dL) HDL-C Lower (40.5 Vs 46.4 mg/dL) Lp(a) Higher (29.3 Vs 25.9 mg/dL) Atherogenic Dyslipidemia A study of Asian Indians living in the United States found that 54% of men had an HDL level below 40 mg/dL, and 68% of women had levels below 50 mg/dL. In the United States, 43% of Asian Indian males and 24% of Asian Indian females have levels that exceed 150 mg/dL. Lipoprotein(a) is still considered an emerging risk factor in the US population at large, but appears to be a major risk factor in Asian Indians.5,26-29 A high level of Lp(a) is the most prevalent dislipidemia in patients with premature CHD. Lp(a) levels are governed almost exclusively by race, ethnicity, and genetics, unlike other lipids, where the levels are influenced by age, gender, diet, and other environmental factors.30-33 Although Lp(a) levels >30 mg/dL are generally considered the threshold at which high risk of premature CHD increases rapidly, levels below 20 mg/dL are considered optimum, particularly in Asian Indians.14,28 Studies of Asian Indians in North America found that 25% to 50% of sampled populations have levels >30 mg/dL. Lp(a) – binds to plasminogen receptors and prevents activation of Plasminogen (which is fibrinolytic on activation to plasmin) Indians living in the US - 54% of men and 68% of women had low HDL levels. Similarly, 43% of Indian males and 24% Indian females have high TG levels that exceed 150 mg/dL 20th Annual Convention of the American Association of Physicians of Indian OriginClinical Implications: Dyslipidemia in the Asian Indian Population June 29, 2002

13 Why diabetics are more prone to ADD?
07/09/13 Why diabetics are more prone to ADD? ↑HSL Insulin resistance in Type 2 diabetes mellitus leads to increased lipolysis in the fat cells in adipose tissue, because the inhibitory effect of insulin on hormone-sensitive lipase is removed, which leads to increased delivery of free fatty acids (FFAs) to the liver. Type II Diabetes is characterized by insulin resistance IR: Insulin Resistance CE, cholesteryl esters; FFA, free fatty acids; TG, triglycerides. CETP: Cholesterol Ester Transport Protein HN Ginsberg,J Clin Invest. 2000;106:453–458.

14 Why diabetics are more prone to ADD?
07/09/13 Why diabetics are more prone to ADD? ↑HSL Increased Delivery of FFA to liver increases VLDL formation (insulin resistance also increase Apo B formation in the Liver). So plasma VLDL (hence TG level) is increased. IR: Insulin Resistance CE, cholesteryl esters; FFA, free fatty acids; TG, triglycerides. CETP: Cholesterol Ester Transport Protein HN Ginsberg,J Clin Invest. 2000;106:453–458.

15 Why diabetics are more prone to ADD?
07/09/13 Why diabetics are more prone to ADD? ↑HSL VLDL exchanges its TGs with HDL via Cholesterol ester transfer protein (VLDL gives away TG and accepts cholesterol ester from HDL) IR: Insulin Resistance CE, cholesteryl esters; FFA, free fatty acids; TG, triglycerides. CETP: Cholesterol Ester Transport Protein HN Ginsberg,J Clin Invest. 2000;106:453–458.

16 Why diabetics are more prone to ADD?
07/09/13 Why diabetics are more prone to ADD? ↑HSL Pathophysiology of Diabetic Dyslipidemia - HN Ginsberg in J Clin Invest 2000, explains the mechanism of dyslipidemia in Diabetics - Insulin resistance in Type 2 diabetes mellitus leads to increased lipolysis in the fat cells in adipose tissue, because the inhibitory effect of insulin on hormone-sensitive lipase is removed, which leads to increased delivery of free fatty acids (FFAs) to the liver. Increased Delivery of FFA to liver increases VLDL formation (insulin resistance also increase Apo B formation in the Liver). So plasma VLDL (hence TG level) is increased. VLDL exchanges its TGs with HDL via Cholesterol ester transfer protein (VLDL gives away TG and accepts cholesterol ester from HDL) By the same mechanism it exchanges its TG for CE from LDL as well. The TGs now acquired by HDL and LDL are digested by lipoprotein lipase and/or hepatic lipase. LDL thus gets converted to the more atherogenic small-dense LDL and HDL loses its Apo A – 1 which gets excreted through kidneys – lowering HDL levels. IR: Insulin Resistance CE, cholesteryl esters; FFA, free fatty acids; TG, triglycerides. CETP: Cholesterol Ester Transport Protein HN Ginsberg,J Clin Invest. 2000;106:453–458.

19 Dyslipidemia is the single most important CV risk factor for MI
12_84 07/09/13 Dyslipidemia is the single most important CV risk factor for MI INTERHEART 9 Modifiable factors account for 90% of first-MI risk worldwide Dyslipidemia alone accounts for CV risk in 50% of the population Yusuf S et al, Lancet; 364:937-52

20 07/09/13 In dyslipidemia patients with diabetes, CV risk is heightened by 3-4 times as compared to dyslipidemia without diabetes J Stamler et al point out that the data of MRFIT (Multiple Risk Factor Intervention Trial) shows, CV risk is increased by 3-4 times in patients with DM + Dyslipidemia Compared to dyslipidemia alone.

21 Hypertriglyceridemia has a direct relation with insulin resistance
07/09/13 Hypertriglyceridemia has a direct relation with insulin resistance TG levels Insulin levels 150 mg/dl 150 pmol/L 300 mg/dl 325 pmol/L Increased secretion of insulin after a fixed amount of glucose given orally is suggestive of insulin resistance. Such insulin secretion is increased in high TG patients, so high TG has direct relation with the insulin resistance.

22 Hypertriglyceridemia is an independent CV risk factor
27650_85 Hypertriglyceridemia is an independent CV risk factor For every increase in TG level of 89 mg/dL, CVD risk increases by 32% in men and 76% in women Meta-analysis of 17 studies (> 55,000 patients) A meta-analysis of 17 studies (> 55,000 patients) has shown that for every increase in TG level of 89 mg/dL, CVD risk increases by 32% in men and 76% in women. And concludes that Hypertriglyceridemia is an independent CV risk factor Hokanson JE et al. J Cardiovasc Risk. 1996; 3:

23 Hypertriglyceridemia in diabetes is an independent CV risk factor
27650_85 Hypertriglyceridemia in diabetes is an independent CV risk factor Asian study of diabetic patients (followed up for 4.6 years) Hypertriglyceridemia in T2DM patients increase CV risk by 3 times compared to T2DM patients without high TG. Even an Asian study has pointed out that high TG in T2DM increases CV risk by 3 times Diabetes Metab Res Rev Mar-Apr;21(2):183-8.

24 Overall CHD Risk Ratio*
6_85 07/09/13 Patients in highest tertile of serum TG had 72% higher risk of CVD than those in lowest tertile Meta-Analysis of 29 Studies Groups CHD Cases CHD Risk Ratio* (95% CI) Duration of follow-up ≥10 years 5,902 <10 years 4,256 Sex Male 7,728 Female 1,984 Fasting status Fasting 7,484 Non-fasting 2,674 Adjusted for HDL Yes 4,469 No 5,689 Overall CHD Risk Ratio* N = 2,62,525 Triglyceride Level Is Significant CVD Risk Factor: Recent Meta-Analysis of 29 Studies: A recent meta-analysis by Sarwar et al1 included 29 prospective studies and was the largest and most comprehensive epidemiological assessment of the association between triglyceride values and CHD risk in Western populations ( participants; 10,158 CHD cases). A combined analysis of the 29 studies yielded an adjusted odds ratio of 1.72 (95% CI, ) in a comparison of extreme thirds of usual triglyceride values (ie, individuals with usual log-triglyceride values in the top third of the population compared with those in the bottom third). This odds ratio was adjusted in all but one study for at least age, sex, smoking status, lipid concentrations, and most studies also adjusted for blood pressure. The above figure shows the CHD risk ratio adjusted for several established risk factors and grouped according to several study characteristics (ie, duration of follow-up, sex, fasting status, and adjusted for HDL-cholesterol). The data indicate that the impact of triglycerides on CHD risk is similar in women and men and also regardless of duration of follow up. The data suggest no important differences in the strength of associations between triglycerides and CHD in studies of fasting participants compared with studies of nonfasting participants. Finally, adjustment for HDL-cholesterol attenuated the magnitude of the association between triglyceride level and CHD risk. The conclusion of the study is that there is a strong and highly significant association between triglyceride value and CHD risk. Reference 1. Sarwar N, et al. Circulation. 2007;115: 1.72 ( ) 1 2 3 Increased Risk Sarwar N, et al. Circulation. 2007;115: *Individuals in top versus bottom third of usual log-triglyceride values, adjusted for at least age, sex, smoking status, lipid concentrations, and blood pressure (most) 24

25 Hazard Ratio for CHD is directly related to TG concentration
CHD risk is directly proportional to serum triglycerides in a large study of > 3,00,000 patients. The odds ratio for coronary heart disease was 1.18 (95% CI ; p=2.6x10(-7)) per C allele, which was concordant with the hazard ratio of 1.10 (95% CI ) per 16% higher triglyceride concentration recorded in prospective studies T>C was significantly associated with higher VLDL particle concentration (mean difference per C allele 12.2 nmol/L [95% CI ]; p=9.3x10(-8)) and smaller HDL particle size (0.14 nm [ ]; p=7.0x10(-5)), factors that could mediate the effects of triglyceride. These data are consistent with a causal association between triglyceride-mediated pathways and coronary heart disease The Emerging Risk Factors Collaboration JAMA November 11; 302(18): 1993–2000

26 60418_85 07/09/13 Increased CV risk can be due to other serious consequences of hypertriglyceridemia Low levels of HDL-C The presence of sd-LDL-C particles The presence of atherogenic triglyceride-rich lipoprotein remnants   Insulin resistance Increases in coagulability and viscosity Pro-inflammatory status The Above consequences may be related to high CV risk of high TG Miller M.

28 Relevance of TG<100 mg/dL - lower the TG lower the sd-LDL-C
07/09/13 Relevance of TG<100 mg/dL - lower the TG lower the sd-LDL-C At fasting TG<100 mg/dL, 85% population has predominant large buoyant LDL particles while if fasting TG>250 mg/dL 85% of population has predominant sd-LDL-C particles. sd-LDL is known to be more atherogenic, keeping TG at mg/dL may not be optimal to reduce atherosclerosis Pattern B: a predominance of small, dense LDL particles Pattern A: large, more buoyant LDL particles predominate Most doctors believe that TG lowering drugs (PPAR Alpha agonists) are not required except when TG > 250 mg/dl.  A following reference suggests that 85 % of total LDL will be Small Dense LDL(sdLDL). when TG is 250. so to reduce the sdLDL, TG should be reduced to 100 mg/dl (when sdLDL is just 15%). As sdLDL is known to be more atherogenic, keeping TG at may not reduce atherosclerosis completely. and target of TG < 100 mg/dl  may be considered. ALP – Atherogenic Lipoprotein Phenotype "A threshold appears to exist for a fasting TG concentration above which there will be a predominance of small, dense LDL particles(pattern B) and below which large, more buoyant particles will predominate (pattern A). The TG concentration that produces a shift from one subclass pattern to another varies with each patient. At a fasting TG concentration ,100 mg/dL, 85% of the population has pattern A, whereas at a fasting TG concentration .250 mg/dL, 85% will have pattern B   17. Thus, lowering the TG concentration from 600 mg/dL to 260 mg/dL is unlikely to change a patient’s LDL particle size because most patients have a threshold for shifting LDL subclass pattern within the range of 100 to 250 mg/dL" Austin et al, Circulation. 1990; 82:

07/09/13 Lets look how TG reduction benefits in outcome…

31 07/09/13 Myth:There is a widespread myth that PPARalpha agonists do not reduce CV events in diabetics (e.g. primary analysis if FIELD and ACCORD) FACT : Sub-analysis of the above two trials show benefit in high TG and low HDL

32 CV benefits of PPAR alpha agonists
07/09/13 CV benefits of PPAR alpha agonists VA-HIT: Primary Endpoint (non-fatal MI and CHD death) BIP study 3090 CAD patients were randomized to bezafibrate vs Placebo, primary end point was fatal, nonfatal MI/sudden death Follow up:6.2 yrs 2500 CHD patients randomized to gemfibrozil or placebo follow up; 5 yrs CV benefits were seen in studies like VA-HIT (Gemfibrozil – in all patients) and BIP (Bezafibrate in patients with TG > 200 mg/dl) studies Rubins HB et al, N Eng J Med, August 5, 1999 Vol. 341; BIP Study Group Circulation. 2000;102:21-27

33 4_85 10_85 07/09/13 Let’s understand what the FIELD trials show about the benefits of PPAR- α therapy 9795 patients, Age years, type 2 diabetes diagnosed after age 35 years, no clear indication for cholesterol-lowering therapy at baseline (total cholesterol mg/dL, plus either total cholesterol to HDL ratio ≥4.0 or triglyceride >88.6 mg/dL Baseline Lipid levels: LDL-C mg/dL (mean) TC mg/dL (mean) HDL-C 43 mg/dL (mean) TG mg/dL (median) Placebo N=4900 Fenofibrate (200 mg) N=4895 Keech A et al found that Fenofibrate did not significantly reduce the risk of the primary outcome of coronary events. It did reduce total cardiovascular events, mainly due to fewer non-fatal myocardial infarctions and revascularisations. The higher rate of starting statin therapy in patients allocated placebo might have masked a moderately larger treatment benefit. Thru this study they were also trying to find out if fenofibrate had a pleiotropic benefit like statins. Endpoints Primary - Composite of CHD death or non-fatal MI at 5 year follow-up Secondary - Composite of total CV events, CV mortality, total mortality, stroke, coronary revascularization and all revascularization at 5 year follow-up Keech A et al, Lancet 2005; 366: 1849–61

34 PPAR-α agonist showed no clear benefit in primary endpoints
34 34 PPAR-α agonist showed no clear benefit in primary endpoints Composite CHD death or nonfatal MI at 5 Years (% of treatment arm) p=0.16 N= 9795 In FIELD study, the difference in primary outcome was insignificant between the two groups, which is responsible for the “perception” that the study failed. Fenofibrate did not show pleiotropic benefits. Perception is that FIELD trial failed, but lets look critically at high TG Population or Atherogenic Dyslipidemics.. Lancet 2005; 366: 1849–61

35 07/09/13 PPAR-α agonists reduce CV events in T2DM patients with high TG and low HDL (ADD) FIELD: Sub-analysis :Total CV events in patients with Metabolic Syndrome ↓23% ↓27% % patients developing events % patients developing events In the subgroups of > 2000 patients (High TG and High TG + Low HDL) , PPAR alpha agonist therapy significantly reduced CV events by 23% and 27% respectively P=0.01 N=2517 P=0.005 N=2014 R Scott et al, Diabetes Care 32:493–498, 2009

36 Let’s also look at what ACCORD trials show about the benefits of PPAR-α therapy
5518 patients with type 2 diabetes (HbA1c > 7.5%) who were being treated All patients were on open-label simvastatin. Median Age: 62.3 years % patients had CVD. Baseline: TG: 162 mg/dl TC: mg LDL: mg/dl HDL: 38.6 mg/dl Fenofibrate 160 mg Placebo In ACCORD, the DM patients were given PPAR alpha agonist or placebo. All patients were on simvastatin at baseline The primary outcome was the first occurrence of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes. The mean follow-up was 4.7 years. ACCORD Study Group. N Engl J Med. 2010;362:

37 % patients developing primary end Point
07/09/13 However, ACCORD results did not show any significant CV benefits in overall population The annual rate of the primary outcome was 2.2% in the fenofibrate group and 2.4% in the placebo group (hazard ratio in the fenofibrate group, 0.92; 95% confidence interval [CI], 0.79 to 1.08; P = 0.32) P=0.32 % patients developing primary end Point Difference in the 2 groups was not significant ACCORD Study Group. N Engl J Med. 2010;362:

39 Limitation & Learning from FIELD & ACCORD Trial
51203_85 07/09/13 Limitation & Learning from FIELD & ACCORD Trial FIELD Study Limitation More patients in the placebo group (17%) than in the PPAR-alpha agonist group(8%) received the non-study lipid-lowering agents (predominantly statins) . Learning If adjustment is done for statin therapy then PPAR-alpha agonist reduces CHD risk by 19% (p = 0.01) PPAR-α agonist significantly reduces CV events by 27% in patients with TG>204 & low HDL-C PPAR-α agonist therapy reduced CV events significantly by 31% in patients with high TG and Low HDL who were already on statin at the time of randomization and continued throughout the trial FIELD Study In FIELD, PPAR agonist therapy was successful to improve CV outcome in T2DM patients with high TG and low HDL if the difference in statin therapy was adjusted While in ACCORD such benefits were seen in similar patients even were patients were on statin from the baseline ACCORD Study

40 Change in relative Risk (%)

Fibrate therapy produced a 10% RR reduction (95% CI 0-18) for major cardiovascular events (p=0.048) and a 13% RR reduction (7-19) for coronary events (p<0.0001), but had no benefit on stroke (-3%, -16 to 9; p=0.69). We noted no effect of fibrate therapy on the risk of all-cause mortality (0%, -8 to 7; p=0.92), cardiovascular mortality (3%, -7 to 12; p=0.59), sudden death (11%, -6 to 26; p=0.19), or non-vascular mortality (-10%, -21 to 0.5; p=0.063). Fibrates reduced the risk of albuminuria progression by 14% (2-25; p=0.028). Serious drug-related adverse events were not significantly increased by fibrates ( participants, 225 events; RR 1.21, ; p=0.19), although increases in serum creatinine concentrations were common (1.99, ; p<0.0001). Fibrates can reduce the risk of major cardiovascular events predominantly by prevention of coronary events, and might have a role in individuals at high risk of cardiovascular events and in those with combined dyslipidaemia P<0.0001 18 trials metaanalysis, > patients Jun M et al, Lancet 2010; 375: 1875–84

49 Non-HDL-C Vs LDL-C for CV risk in healthy women
In a prospective study of healthy 15,632 women who were followed up for 10 years, strength of association between different lipid parameters (HDL-C, LDL- C, non-HDL-C) and CV risk were measured. Conclusion Non-HDL-C was a stronger indicator of CV risk than LDL-C Self-explanatory Paul Ridkar JAMA. 2005;294:

50 Non-HDL-C is a better indicator of residual risk than LDL-C
When triglycerides are > 200 mg/dL but < 500 mg/dL, a non–HDL-C calculation will provide better risk assessment than LDL-C alone If insulin resistance is suspected, evaluate non–HDL-C to gain useful information regarding the patient’s total atherogenic lipoprotein burden.

51 Non-HDL-C is better than ApoB for the CV risk prediction
A meta analysis was carried out including 25 trials of different types of lipid lowering therapies (12 on statin, 4 on fibrate, 5 on niacin, 2 on simvastatin– ezetimibe, 1 on ileal bypass surgery, and 1 on aggressive versus standard low-density lipoprotein (LDL) cholesterol, n=131,134) Conclusion Non-HDL-C decrease outperforms ApoB decrease for prediction of CHD and CVD risk. Its decrease is a better predictor of CHD and CVD Importance of non-HDL: Non-high-density lipoprotein (non-HDL) cholesterol decrease outperformed apoB decrease for prediction of coronary heart disease and is a better predictor of CHD Robinson J,,Am J Cardiol 2012;110: 1468–1476

52 Importance of Non-HDL-C vis-à-vis LDL-C and ApoB for CV events in statin treated patients
A meta-analysis was carried out from 8 landmark statin trials (38,153 patients), to evaluate the relative strength of the associations of LDL-C, non–HDL-C, and ApoB with cardiovascular risk among patients treated with statin therapy. Conclusion Non-HDL-C was a better indicator of CV risk than ApoB (p=0.02) and LDL –C (p=0.002) (1 SD increase in non-HDL-C, ApoB and LDL-C increase CV risk by 16, 14 and 13% respectively) Among statin-treated patients, on-treatment levels of LDL-C, non–HDL-C, and apoB were each associated with risk of future major cardiovascular events, but the strength of this association was greater for non–HDL-C than for LDL-C and apoB 8 studies: 4S, LIPID , AFCAPS, WOSCOPS, CARDS, IDEAL, TNT, SPARCL JUPITER Boekholdt S, JAMA. 2012;307(12):

64 3_85 07/09/13 Fibrates do not seem to be the optimal solution for managing residual risk either PROS: Reduction in TG, LDL-C & raises HDL-C, used alone or in conjunction with statins CONS: Increased risk of gall stones Abnormal Liver Function Tests (increased AST and ALT levels) in 7.5% patients Increased serum creatinine levels. Fibrates are effective to control High TG, but they have many disadvantages like hepatotoxicity, gall stones, reduced serum creatinine, etc Ref - TRICOR Prescribing Information

71 The importance of controlling both glucose and lipid levels in Diabetic dyslipidemia gave rise dual agonists PPARα is found in the liver, kidney, heart, skeletal muscle and vasculature, is implicated in the uptake and oxidation of fatty acids and lipoprotein metabolism. PPARgamma is mainly expressed in adipose tissue with lower expression detected in a wide range of differing tissues like spleen, intestine, pancreas, colon, kidney, skeletal muscle and macrophages. PPARγ agonists have beneficial effects on glucose homeostasis by increasing insulin sensitivity and glucose disposal and prevent the loss of beta cell mass in the pancreas. Fibrates are PPARα agonist used for triglyceride lowering in clinics and PPAR gamma agonists, Rosiglitazone and Pioglitazone are proven to be efficacious as insulin sensitizing agents for the treatment of type 2 diabetes. Diabetes Aug;54(8):

72 RGZ/FEB was more effective and safe than RGZ alone
Combination therapy of PPARα & PPARγ agonists, results in reduction of TG & A1c levels without increasing body weight in T2DM patients In a study, obese, T2DM patients were treated with placebo for 2 months and then rosiglitazone (8 mg/day) + Fenofibrate (160 mg/day)(RGZ/FEB) or rosiglitazone (8 mg/day) (RGZ) alone for 2 months. RGZ/FEB was more effective and safe than RGZ alone RGZ/FEB lowered fasting plasma FFA more effectively than RGZ alone (22 vs. 5%, P < 0.05), and More effective than RGZ alone in lowering A1c (0.9 vs. 0.4%)and TGlevels (38 vs. 5%) RGZ/FFB prevented the fluid retention usually associated with RGZ (1.6 vs. 5.6%, P < 0.05) Conclusion The combination of Rosi + Feno decreased FFA, TG, HbA1c more than Rosi alone. The combination also prevented the fluid retention associated with Rosi alone Boden G, et al. Diabetes 56:248–255,2007
