ADVANCE Figure 3. Cumulative Incidences of Events, According to Glucose-Control Strategy. The hazard ratios for intensive glucose control as compared with standard glucose control were as follows: for combined major macrovascular or microvascular events, 0.90 (95% confidence interval [CI], 0.82 to 0.98) (Panel A); for major macrovascular events, 0.94 (95% CI, 0.84 to 1.06) (Panel B); for major microvascular events, 0.86 (95% CI, 0.77 to 0.97) (Panel C); and for death from any cause, 0.93 (95% CI, 0.83 to 1.06) (Panel D). The vertical dashed lines indicate the 24-month and 48-month study visits, at which additional data on microvascular events were collected, specifically the ratio of urinary albumin to creatinine and results of a retinal examination. For events relating to these data, the event time was recorded as the date of the visit. The curves were truncated at month 66, by which time 99% of the events had occurred. The effects of treatment (hazard ratios and P values) were estimated from unadjusted Cox proportional-hazard models that used all the available data. Randomized 11,140 diabetic patients to tight vs. less tight glycemic control After 5 year follow up, no significant benefit on major macrovascular event or death Cumulative Incidences of Events, According to Glucose-Control Strategy The ADVANCE Collaborative Group.

This was a retrospective cohort study involving the records of 23,915 patients with type 2 diabetes who initiated monotherapy with metformin (n = 12,774), glipizide (n = 4,325), glyburide (n = 4,279) or glimepiride (n = 2,537). Subjects were all at least 18 years of age, with and without a history of CAD, and not on insulin or a non-insulin injectable at baseline. The primary outcome was all-cause mortality. An increase in overall mortality risk was observed in the entire cohort (left panel) with glipizide (HR 1.64; 95% CI ), glyburide (HR 1.59; 95% CI ), and glimepiride (HR 1.68; 95% CI ) vs. metformin. However, in patients with documented CAD (right panel), a statistically significant increase in overall mortality risk was only found with glipizide (HR 1.41; 95% CI ) and glyburide (HR 1.38; 95% CI ) vs. metformin. It is important to note that since the patients were not randomly assigned to one therapy or the other, there may have been biases introduced in terms of which medications they were started on (i.e., perhaps sicker patients were not started on metformin).

49 Current Treatment Paradigm
Give more and more insulin to control blood sugars Insulin Resistance (Diabetes) Increase Insulin

50 Current Treatment Paradigm
Treatments to reduce glucose often increase insulin levels Investigators considered only gluco-toxicity but not insulin toxicity The disease is insulin resistance but the treatment is hyperglycemia Insulin cures type I diabetes Insulin causes type II diabetes

51 Current Treatment Paradigm is Idiotic
Like treating alcoholism with alcohol! If you have a type 2 DM patient treated with Insulin – it is almost certainly wrong! Increasing insulin resistance! Diabetes Care :23-31 Henry RR You can’t treat a hyperinsulinemic state with insulin!

52 Diabetes is getting worse!
Metformin Glyburide More Insulin More Insulin Metformin Insulin Consider this: pts start on metformin then more drug and more drug – then insulin then more and more – their diabetes is not getting better over the years it is getting WORSE! Our treatment makes diabetes worse, but sugars better – then we wonder why pts are getting worse so we call it a chronic progressive disease – when in fact, the only thing chronic about it is our own stupidity! Over Time

53 Diabetes Screening is Useless
20 184 individuals aged 40–69 years (mean 58 years), at high risk of prevalent undiagnosed diabetes During 184 057 person-years of follow up (median duration 9·6 years), there were 1532 deaths in the screening practices and 377 in control practices (mortality hazard ratio [HR] 1·06, 95% CI 0·90–1·25) – if anything – increased mortality Screening useless if treatment is incorrect!

For saxagliptin (Onglyza), the relative risk reduction of cardiovascular events was calculated to be 0.43 in a meta-analysis of 4,607 patients, with confidence intervals of 0.23 and 0.80. For linagliptin (Trajenta), the relative risk reduction was calculated to be 0.34 in a meta-analysis of 5,239 patients, with confidence intervals of 0.16 and It is important to note that the main contributor to the number of events was a head-to-head study of linagliptin vs. sulfonylureas. When linagliptin was compared to placebo, the comparison was not statistically significant (per Trajenta Canadian Product Monograph, July 2011). Given the fact that the study program for each of the drugs varied considerably with regard to study population, comparator, duration of follow-up, etc., one should not compare the results of one drug vs. another.

The primary outcome investigated was major cardiovascular events (MACE, reported as serious adverse events) together with death from any cause. The analysis included a total of 70 trials enrolling 41,959 patients. Mean follow-up was 44.1 weeks. Overall, the odds ratio (OR) for MACE was reported to be 0.71, a statistically significant result vs. comparators (95% CI 0.59 to 0.86, p < 0.001). Significant reductions in risk of acute myocardial infarction (MI) and all-cause mortality were also reported (OR 0.64 for MI and 0.60 for all-cause mortality). For the primary endpoint, two individual DPP-4 inhibitors, saxagliptin (Onglyza; 13 studies) and vildagliptin (16 studies), were also associated with significant reductions in risk vs. comparators. The ORs for sitagliptin (Januvia; 27 studies), linagliptin (Trajenta; 9 studies) and alogliptin (5 studies), while all numerically in favor of these treatment agents, did not reach statistical significance. Again, given the fact that the study program for each of the drugs varied considerably with regard to study population, comparator, duration of follow-up, etc., one should not compare the results of one drug vs. another. The reductions in risk were seen early (the duration of most of the trials was only about 1 year). Reference: Monami M, Ahrén B, Dicembrini I, et al.
