FDA Approves New Drug to Treat Type I and Type II Diabetes

The Food and Drug Administration (FDA) today approved Symlin, an injectable medicine to control blood sugar for adults with type 1 and type 2 diabetes. Symlin is to be used in addition to insulin therapy in patients who cannot achieve adequate control of their blood sugars on intensive insulin therapy alone. Symlin will be the only therapy for the treatment of type 1 diabetes other than in...

Chemists identify key gene in development of type 1 diabetes

Chemists say they have identified a gene that appears to play a key role in the development of type 1 diabetes, also known as insulin-dependent or juvenile diabetes, a disease that affects about one million people in the U.S. and is on the rise worldwide. They described their findings, which they say could lead to new drug interventions and possibly gene therapy, today at the 229th national meeti...

Rare surgery performed to remove pancreas, prevent diabetes

In a 12-hour, dual-stage surgery known to be performed at only two other centers in the U.S., doctors at the University of Alabama at Birmingham on Tuesday returned a patient's own insulin-producing cells to him after surgically removing his pancreas to eliminate constant, severe pain from chronic pancreatitis. The patient, Leonard Stewart, 47, of Panama City, Fla., remained anesthetized i...

First North American Encapsulated Islet Transplant without Long-term Immune Suppression into a Patient with Type 1 Diabetes

Biologists at the University of Liverpool have discovered how the plagues of the Middle Ages have made around 10% of Europeans resistant to HIV. Scientists have known for some time that these individuals carry a genetic mutation (known as CCR5-delta32) that prevents the virus from entering the cells of the immune system but have been unable to account for the high levels of the gene in Scandinavi...

Future diabetes drugs may target new protein interaction

In the March 3 issue of Nature, Johns Hopkins researchers report that two proteins best known for very different activities actually come together to turn the liver into a sugar-producing factory when food is scarce. Because the liver's production of sugar is a damaging problem in people with diabetes, the proteins' interaction might be a target for future drugs to fight the disease, the research...

Single-donor Islet Transplantation Procedure Shows Promise For Patients With Type 1 Diabetes

Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

Scientists at Washington University School of Medicine in St. Louis have learned that a temporal "window of opportunity" was critical to their earlier successes in treating diabetic rats with embryonic pig tissues. In those experiments, published in 2004, researchers were surprised to find that they didn't have to give anti-rejection drugs to diabetic rats treated with embryonic pig cell...

Malfunctioning bone marrow cells sabotage nerve cells in diabetes

Malfunctioning bone marrow cells that produce insulin appear to cause a dangerous nerve condition called neuropathy that disables many people with diabetes, said a research team led by Baylor College of Medicine in Houston. The report from researchers at BCM, Shiga University of Medical Science in Japan, and the University of Chicago appears online today in the Proceedings of the National...

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

A key obstacle to early detection of type 1 diabetes - as well as to rapid assessment of the effectiveness of therapeutic intervention - has been the lack of direct, non-invasive technologies to visualize inflammation in the pancreas, an early manifestation of disease. Instead, clinicians have had to await overt symptoms before diagnosing an individual, by which time destruction of the insulin-pr...

UCSD study clarifies insulin's role in blocking release of energy in patients with type II diabetes

Chronically high levels of insulin, as is found in many people with obesity and Type II diabetes, may block specific hormones that trigger energy release into the body, according to researchers at the University of California, San Diego (UCSD) School of Medicine.
