Diabetes: Losing weight 'can reverse disease long-term'
Patients who reverse their diabetes and then keep their weight down can remain free of the condition, new research has found.
The study found that even people who have had Type 2 diabetes for up to 10 years can reverse their condition after adopting a very low calorie diet.
Professor Roy Taylor, a world expert on the condition which affects two-and-a-half million people in this country and is growing, published his latest findings in the journal Diabetes Care.
The Professor of Medicine and Metabolism at Newcastle University has previously shown that patients with Type 2 diabetes who successfully lose weight can reverse their condition because fat is removed from their pancreas, returning insulin production to normal.
A study led by Professor Taylor five years ago showed that diabetes could be reversed by a very low calorie diet.
International interest was sparked but the study only lasted eight weeks and the question remained whether the diabetes would stay away.
In this new study, 30 volunteers with Type 2 diabetes embarked on the same diet of 600 to 700 calories a day.
Participants lost on average 14 kilograms - just over 2 stone. Over the next six months they did not regain any weight.
The group included many people with longer duration diabetes, defined as more than eight years and ranging up to 23 years.
Overall, 12 patients who had had diabetes for less than 10 years reversed their condition and six months later they remained diabetes free.
In fact, after six months a 13th patient had reversed their dia Continue reading

Transmission of Diabetes Prion-Like Aggregates Triggers Disease Symptoms

Protein misfolding disorders (PMDs) such as Alzheimer’s disease (AD), Parkinson’s disease (PD), and amyotrophic lateral sclerosis (ALS), are characterized by the accumulation of misfolded protein aggregates in tissues including the brain. A few rare PMDs, such as bovine spongiform encephalopathy (BSE, or mad cow disease), and Creutzfeldt-Jacob Disease (CJD), can even be transmitted between humans or from animals to humans. In these cases, exposure to the causative misfolded protein aggregates, known as prions, triggers the transformation of normal proteins into the abnormal form. Effectively, prions "seed" the development of misfolded protein aggregation in the brain of the recipient, and this leads to the accumulation of toxic substances that destroy neurons.
Protein aggregation isn’t limited to the widely recognized PMDs, however. About 90% of patients with type 2 diabetes (T2D) develop pancreatic islet deposits of the peptide hormone islet amyloid polypeptide (IAPP). These misfolded protein aggregates start accumulating many years before the clinical diagnosis of T2D, explain Abhisek Mukherjee, Ph.D., and Claudio Soto, Ph.D., who head a research team at McGovern Medical School at The University of Texas Health Science Center at Houston that studies the molecular basis of PMDs, including AD, PD, and prion diseases.
Previous post mortem and animal studies have suggested that islet IAPP aggregation is linked with key T2D features, including the loss of beta cell mass, but the how these IAPP deposits cause disease development or progression isn’t yet understood. One Continue reading

World Diabetes Day

Tuesday November 14th is World Diabetes Day. The International Diabetes Federation (IDF) defines diabetes as follows:
“Diabetes is a chronic disease that occurs when the pancreas is no longer able to make insulin, or when the body cannot make good use of the insulin it produces. Insulin is a hormone made by the pancreas, that acts like a key to let glucose from the food we eat pass from the blood stream into the cells in the body to produce energy. All carbohydrate foods are broken down into glucose in the blood. Insulin helps glucose get into the cells.
Not being able to produce insulin or use it effectively leads to raised glucose levels in the blood (known as hyperglycaemia). Over the long-term high glucose levels are associated with damage to the body and failure of various organs and tissues.”
Note the mention of the word “glucose” five times and the acknowledgment that all carbohydrate foods are broken down into glucose.
The different types
The IDF definition describes the two types of diabetes – type 1 diabetes is the type where the body is no longer able to make insulin and type 2 diabetes is the type where the body cannot make good use of the insulin it produces.
We used to call type 1 diabetes (T1D) “juvenile diabetes”, as it only used to occur in young people. The typical age of onset was during teenage years – some children developed type 1 younger and a few in their early 20s, but it was largely a teenage condition. If you hadn’t developed T1D by the time of your 21st birthday, you were highly unlikely to do so.
Type 2 diabetes (T2D) used to b Continue reading

Why Sleep Is Important With Diabetes

People with diabetes hear constantly to exercise, eat right, and check blood sugars. Doctors rarely mention the importance of sleep, but good sleep is among the best diabetes medicines.
A paper from Penn State University found that the risk of death from stroke and heart disease was significantly higher in people who get less than six hours of sleep a night. Researcher Julio Fernandez-Mendoza, PhD, said, short sleep “multiplies the risk of poor outcomes in people with CVD [cardiovascular disease] or stroke.” Heart disease and stroke are the leading causes of diabetes-related deaths.
“We have to look beyond sleep apnea,” said Dr. Fernandez-Mendoza. “Most of these patients without sleep apnea but with coronary vascular disease or stroke complain of poor sleep or chronic insomnia. We know now that when such objective short sleep is present their long-term prognosis is much worse.”
Obstructive sleep apnea (OSA) has been known for years to increase risk of Type 2 diabetes, heart disease, and early death. In sleep apnea, people stop breathing repeatedly while asleep, because their airways are blocked by relaxing throat muscles. They wake up to clear their throat so they can breathe and then fall back asleep, over and over, usually without being aware of it. Penn State researchers found that people with OSA had three times the risk of Type 2 diabetes and four times the risk of high blood pressure (hypertension.)
According to the American Sleep Association, “animal studies show that sleep is necessary for survival.” The immune system, our bodies’ repair system, is Continue reading

Type 1 diabetes cured in mice using gene therapy

Researchers from the University of Texas Health Science Center in San Antonio have found a way to cure type 1 diabetes in mice. It is hoped that the novel technique - which boosts insulin secretion in the pancreas - will reach human clinical trials in the next 3 years.
Study co-author Dr. Bruno Doiron, Ph.D., of the Division of Diabetes, and colleagues recently reported their findings in the journal Current Pharmaceutical Biotechnology.
Type 1 diabetes is estimated to affect around 1.25 million children and adults in the United States. Onset of the condition is most common in childhood, but it can arise at any age.
In type 1 diabetes, the immune system destroys the insulin-producing beta cells of the pancreas. Insulin is the hormone that regulates blood glucose levels. As a result, blood glucose levels become too high.
There is currently no cure for type 1 diabetes; the condition is managed through diet and insulin therapy. However, in recent years, researchers have investigated replacing beta cells as a means of eradicating type 1 diabetes once and for all.
Dr. Doiron and colleagues have taken a different approach with their new study. The team reveals how they used a method called gene transfer to coax other pancreatic cells into producing insulin.
Using this technique, the researchers have managed to cure type 1 diabetes in mice, bringing us one step closer to curing the condition in humans.
