Pancreatic islet allo-transplantation is a procedure in which islets from the pancreas of a deceased oran donor are purified, processed, and transferred into another person. Immunosuppressive medications are needed to prevent rejection which is a typical challenge with any transplant. These medications carry a number of serious side effects such as decreased kidney function, high blood pressure, anemia and lowered white blood cells counts.
Type 2 diabetes has long been known to progress despite glucose-lowering treatment, with 50% of individuals requiring insulin therapy within 10 years (1). This seemingly inexorable deterioration in control has been interpreted to mean that the condition is treatable but not curable. Clinical guidelines recognize this deterioration with algorithms of sequential addition of therapies. Insulin resistance and β-cell dysfunction are known to be the major pathophysiologic factors driving type 2 diabetes; however, these factors come into play with very different time courses. Insulin resistance in muscle is the earliest detectable abnormality of type 2 diabetes (2). In contrast, changes in insulin secretion determine both the onset of hyperglycemia and the progression toward insulin therapy (3,4). The etiology of each of these two major factors appears to be distinct. Insulin resistance may be caused by an insulin signaling defect (5), glucose transporter defect (6), or lipotoxicity (7), and β-cell dysfunction is postulated to be caused by amyloid deposition in the islets (8), oxidative stress (9), excess fatty acid (10), or lack of incretin effect (11). The demonstration of reversibility of type 2 diabetes offers the opportunity to evaluate the time sequence of pathophysiologic events during return to normal glucose metabolism and, hence, to unraveling the etiology.
This seems hard to do, but really it’s not if you know one secret: Replace snacking with something far more satisfying — fat. That’s right, the government is wrong to recommend a low fat diet. Fat is what makes you feel full until your next meal. Take away the fat, take away the full. Don’t go to an extreme, but do lean strongly toward a high-fat low-carb diet.
