New treatments for diabetes type 2

There is urgent need for new treatment strategies for diabetes type 2.

Some new approaches include:

- Long acting (eg, once weekly) agonists of the glucagon-like-peptide-1 receptor - they improve prandial insulin secretion, reduce excess glucagon production, and promote satiety

- inhibitors of dipeptidyl peptidase 4 (DPP-4), which enhance the effect of endogenous incretin hormones

- inhibitors of the sodium—glucose cotransporter 2, which increase renal glucose elimination

- inhibitors of 11β-hydroxysteroid dehydrogenase 1, which reduce the glucocorticoid effects in liver and fat

- Insulin-releasing glucokinase activators and pancreatic-G-protein-coupled fatty-acid-receptor agonists, glucagon-receptor antagonists, and metabolic inhibitors of hepatic glucose output are also being assessed

Emily Lu - Question is - how many of these treatments will actually be available to minority groups that have the higher prevalence of diabetes?

Ves Dimov - Excellent question. Check this one too: "By 2030, the number of individuals with diabetes worldwide is expected to rise to half a billion (470 million) - almost 80% of whom will be in low-income and middle-income countries. In these regions, diabetes drugs and insulin are often inaccessible or are too expensive." Early diet intervention may be the answer in type 2 diabetes.

Emily Lu - "Early diet intervention may be the answer in type 2 diabetes." -- True enough, but much much easier said than done! Patient education in general seems to me to be critical as well.

Ves Dimov - Diet is difficult to implement from patient's perspective. Activity did not bring the expected benefits in the latest trial - reported in the July 2011 issue of the Lancet.

  1. I also think that there is need for new treatment strategies for diabetes in-spite of giving Insulin.
