Glucosamine Causes The Death Of Pancreatic Cells

Glucosamine Causes The Death Of Pancreatic Cells

High doses or prolonged use of glucosamine causes the death of pancreatic cells and could increase the risk of developing diabetes, according to a team of researchers at Université Laval's Faculty of Pharmacy. Details of this discovery were recently published on the website of the Journal of Endocrinology.

In vitro tests conducted by Professor Frédéric Picard and his team revealed that glucosamine exposure causes a significant increase in mortality in insulin-producing pancreatic cells, a phenomenon tied to the development of diabetes. Cell death rate increases with glucosamine dose and exposure time. "In our experiments, we used doses five to ten times higher than that recommended by most manufacturers, or 1,500 mg/day," stressed Professor Picard. "Previous studies showed that a significant proportion of glucosamine users up the dose hoping to increase the effects," he explained.

Picard and his team have shown that glucosamine triggers a mechanism intended to lower very high blood sugar levels. However, this reaction negatively affects SIRT1, a protein critical to cell survival. A high concentration of glucosamine diminishes the level of SIRT1, leading to cell death in the tissues where this protein is abundant, such as the pancreas.

Individuals who use large amounts of glucosamine, those who consume it for long periods, and those with little SIRT1 in their cells are therefore believed to be at greater risk of developing diabetes. In a number of mammal species, SIRT1 level diminishes with age. This phenomenon has not been shown in humans but if it were the case, the elderly - who constitute the target market for glucosamine - would be even more vulnerable.

"The key point of our work is that glucosamine can have effects that are far from harmless and should be used with great caution," concluded Professor Picard.

The results obtained by Picard and his team coincide with recent studies that cast serious doubt on the effectiveness of glucosamine in treating joint problems.

This study was co-authored by Mathieu Lafontaine-Lacasse and Geneviève Doré.

ADDITION: No significant benefit of intensive therapy in diabetes

September 22, 2010 | Lisa Nainggolan

Stockholm, Sweden - Intensive multifactorial treatment was not significantly better than routine care in a study of 3000 patients with newly diagnosed type 2 diabetes treated by general practitioners, at least in terms of the primary outcome, a composite of first cardiovascular events. Results of the Anglo-Danish-Dutch Study in General Practice of Intensive Treatment and Complication Prevention in Type 2 Diabetic Patients Identified by Screening (ADDITION) trial were reported today at the European Association for the Study of Diabetes (EASD) 2010 Meeting by Dr Simon J Griffin (University of Cambridge, UK).

 

Griffin said the study "was pragmatic and relevant to everyday general practice" and shows that "intensive treatment in people with screen-detected diabetes is feasible" in primary care. The lack of a significant effect of the intensive intervention on the primary end point was likely the result of the great improvements in the routine care of diabetes over the course of the study in the three countries involved, Denmark, the Netherlands, and the UK, he commented.

 

"Even in the routine-care group that did not receive significant additional support, cardiovascular risk factors improved in the five years following detection by screening. Our intervention to promote more intensive treatment was associated with statistically significant but relatively modest differences in prescribed treatment, in levels of risk factors, and in the proportion of patients for whom treatment targets were achieved. These relatively small differences were in turn associated with a nonsignificant 17% relative reduction in the incidence of a composite CV end point over five years," he told meeting attendees.

Important to note also, said Griffin, was the fact that maintaining average glycated hemoglobin (HbA_1c) levels of 6.5% in the intensive-treatment arm of the study was not associated with any increased mortality risk. This is seen as particularly important in the wake of the ACCORD results, a trial in which intensive glucose lowering appeared to increase mortality.

Commentators applauded the ADDITION trial, which they noted must have been very difficult to carry out. The invited discussant, Dr William H Herman (University of Michigan, Ann Arbor), explained that all prior studies of this nature have been observational, and this was research that "I personally believed would never be performed." ADDITION demonstrates that primary-care-based stepwise screening for type 2 diabetes "is feasible and identifies patients with substantial levels of cardiovascular risk that is potentially modifiable," said Herman.

Why Dichotomizing Variables is a Bad Idea

This is a nice review from the research perspective, but may be not so practicable without using dichotomized variable of a continuous variable. For example, the criteria of diabetes and hypertension diagnosis are based on dichotomized variables from continuous blood glucose level and blood pressure level.

_From Bob

        It is well recognized in the methodological literature that dichotomization of continuous variables introduces major problems in the analysis and interpretation of models derived in a data-dependent fashion. Nevertheless, dichotomization of continuous variables is widespread in clinical research. Problems include loss of information, reduction in power, uncertainty in defining the cutpoint, arriving at a biologically implausible step function as the estimate of a dose–response function, and the impossibility of detecting a non-monotonic dose–response relation. Uncertainty in how to select a ‘sensible’ cutpoint to group a continuous variable into two classes has led researchers to use either the median or an ‘optimal’ cutpoint. The latter approach gives a highly inflated type 1 error probability, together with biased parameter estimates and variances that are too small [9, 11]. Although some remedies for these diffculties have been developed [9, 21–23], none of the authors of these papers actually recommends the use of ‘optimal’ cutpoints with their proposed corrections. In general, the situation seems hardly to have improved since the advice in 1993 of Maxwell and Delaney [1] to avoid dichotomization, quoted at the beginning of this paper.

Instead of dichotomizing a continuous variable, we prefer to obtain a prognostic index by methodology which combines selection of variables with selection of functions for continuous variables [4, 26]. As stated in an editorial [2] in an epidemiological journal a decade ago, ‘these elegant approaches [fractional polynomials and splines] merit a larger role in epidemiology.’ Clinical researchers should in general avoid dichotomization at the model-building stage and adopt more powerful methods.

In memory of Dr. John Denis McGarry

Dr. Denis McGarry was a great teacher and sage. His lecture affects my way of thinking on diabetes. Unforgettable.

“In 1992, he published a famous paper in Science entitled “What if Minkowski Had Been Ageusic?” (1). In this paper he suggested that scientific concentration on abnormal glucose metabolism had masked the critical importance of abnormal fat metabolism, especially in type 2 diabetes. Subsequent to this paper there was a huge swing by investigators toward the key role of abnormal lipid metabolism in insulin resistance and lipotoxic damage to tissues as diverse as the heart and the β-cell of the pancreas.”

A cell line called HeLa (for Henrietta Lacks) was born. Those immortal cells soon became the workhorse of laboratories everywhere. HeLa cells were used to develop the first polio vaccine, they were launched into space for experiments in zero gravity and they helped produce drugs for numerous diseases, including Parkinson’s, leukemia and the flu. By now, literally tons of them have been produced.

Dr. Gey did not make money from the cells, but they were commercialized. Now they are bought and sold every day the world over, and they have generated millions in profits.

Ukrainian registry of type 2 dm shows U-shaped relation of BMI to mortality
(Heart 2009;95:454-460. doi:10.1136/hrt.2008.150524)

Not too surprising, a common sense is that extreme, fundamental, or radical ends are not good. But one of the interesting figures (finding) is even obese population (≥45) had lower risk of death than low BMI population (<20 for all-cause death, and <21 for CVD death).

Manifest Destiny is an funny video related to the report of recent stable obesity rate.

This is a good omen. This means that we will see the diabetes prevalence going to reach the platform soon.
_____________________________________________
Obesity rate appears to be stabilizing.

ABC World News (1/13, story 8, 0:20, Stephanopoulos) reported, "New numbers today from the CDC show the rate of obesity stabilizing."
The New York Times (1/14, A20, Belluck) reports that "Americans, at least as a group, may have reached their peak of obesity." The good news is that "the numbers indicate that obesity rates have remained constant for at least five years among men and for closer to 10 years among women and children -- long enough for experts to say the percentage of very overweight people has leveled off." The bad news is that "nearly 34 percent of adults are obese, more than double the percentage 30 years ago," while "the share of obese children tripled during that time, to 17 percent," according to studies published online Jan. 13 in the Journal of the American Medical Association.
The first study "examined height and weight data in a nationally representative sample of 5,555 adult Americans collected in 2007 and 2008," the Los Angeles Times (1/14, Stein) reports. "In the sample, 33.8% of the subjects" were "obese." After comparing "those numbers...to ones collected from 1999 to 2006 in a similar sample," researchers found that "among women, obesity statistics remained fairly flat throughout the period encompassed by the two studies," while "obesity rates among men rose slightly during the decade, but leveled off in the later years."
In the second study of nearly 4,000 children ranging in age from two to 19, the Wall Street Journal (1/14, Dooren) reports, researchers found that 17% of the youngsters met the threshold for obesity and 32% could be deemed to be overweight, a pattern similar to what was seen a decade ago. For both studies, the Journal notes that the CDC researchers based their estimates on data derived from the most recent National Health and Nutrition Examination Surveys.
USA Today (1/14, Hellmich) reports that "William Dietz, director of the CDC's Division of Nutrition, Physical Activity and Obesity, says this may reflect that people are becoming aware of 'the adverse health consequences of obesity' and are adopting healthier habits." Still, when it comes to the impact of obesity on children, Cynthia L. Ogden, PhD, the author of both studies, is concerned, because "obese kids are at a greater risk of weight-related health problems such as high cholesterol, blood pressure, and diabetes, plus they are at a greater risk of becoming obese adults, she says."
Bloomberg News (1/14, Ostrow), the AP (1/14, Tanner), Reuters (1/14, Steenhuysen), Time (1/13, Kluger), HealthDay (1/13, Gordon), &&&WebMD (1/13, DeNoon), and &&&HeartWire (1/13, O'Riordan) also covered the story.

"You're going to have the same chip in there, the same genome, but different software. And the outcome is a different cell type."...

High-Fructose Corn Syrup Linked to Obesity, Diabetes


High-fructose corn syrup (HFCS) is also known as corn syrup, isoglucose and fructose on package labels and has been undergoing scrutiny for the last several years. Back in the '80s, when the low-fat craze started, HFCS began to be added to everything as a relatively easy way to add flavor and moisture to lower-fat products. Seemed like a great idea at the time. Corn is in abundance in the United States, and corn syrup is cheap and easy to add to commercially prepared foods. Little did we know that this type of sugar is digested very differently, and unlike glucose, actually prevents you from feeling full even when you have eaten a lot. Here's how it works: You eat something with HFCS and the sugar goes to your liver for processing. There it gets broken down into smaller components and eventually gets broken down completely. This is how all sugars are managed by the body. The problem is HFCS uses a lot more of the cell's energy to breakdown and leaves the cell with less energy to properly metabolize other foods. In addition, the breakdown products of the process cause an increase in lipid levels and triglycerides in the blood and within the cell itself, causing the fat to fill the cell. HFCS metabolism increases circulating insulin levels significantly and results in insulin resistance (the precursor of adult onset diabetes and metabolic syndrome). Lastly, unlike glucose, HFCS byproducts in the blood send a message to the brain that you are still hungry and need to eat. The more you eat, the more you crave! Most other sugars get stored in the cell, not as fat but as a substance called glycogen that can be easily mobilized for energy when needed, unlike the lipid that is formed from HFCS that is hard to mobilize when needed. HFCS leads to fatty liver, high blood lipids and triglycerides, high blood insulin levels and a continued craving to eat even when the body doesn't need any more calories. This is a recipe for central body obesity, heart disease, diabetes and liver failure from fatty deposits. Interestingly, this is the exact outcome when alcohol is consumed (minus the buzz or drunken feeling). If you drink alcohol too much, you get a "beer belly" (central obesity), fatty liver, heart disease from high triglycerides and lipids, and type 2 diabetes. We wouldn't dream of giving our kids alcohol, but as it turns out, HFCS is metabolized in the exact same way with the same damage done, calorie for calorie. For most adults, some alcohol drinking is OK, but excessive use or abuse can lead to serious long-term physical consequences. The same is true for HFCS. By the way, even though fresh fruit contains fructose, because it is "packaged" with natural fiber, it is digested very differently and doesn't cause these changes. Whole, fresh fruit is healthy, but fruit juices, fruit roll-ups and fruit snacks are devoid of the fiber and therefore no better than candy. I encourage families to spend time reading labels and becoming aware of how ubiquitous this additive is. It is in store-bought bread, crackers, pop, cookies, some lunch meats, fruit juices, packaged chocolate milk, candy, all-natural fruit snacks and many other packaged foods. I am not suggesting you need to completely eliminate it from your life, but I encourage you to decrease the amount your family eats every day.
