New LDL Guidelines

LDL, or low density lipoprotein, is the so-called “bad” cholesterol that until recently we have all tried to keep under 100! Well, recent guidelines have drastically changed in order to accommodate results from a large (10,000 patients) study which clearly showed that patients getting to 77 will have a significantly lower risk for a major cardiovascular event (heart attack). Typically, it takes a Statin drug to drop the LDL to that level, although recently one of my diabetic Asian patients has had a documented lab result of 25!!, without any Statin (extremely rare). With these new guidelines, we may need to increase your Statin dose. Please cooperate.

 

 

FDA-Approved New Drug For Diabetics Who Are On Insulin Treatment.

The new drug is called Pramlintide, and has a generic name of Symlin or Amylin. Amylin is actually a pancreatic hormone that is coming out of the Islets, and typically would be secreted along with insulin. It has a dual effect: to stabilize blood glucose fluctuations right after the meal, and to slow gastric emptying. It’s first effect is achieved by suppressing the hormone Glucagon, which would tend to stimulate glucose release by the liver. Clinical trials have shown that it causes a drop of 0.6% in HbA1c, and a weight drop of 3.1 pounds in the 52-week study period. The down-side is that this drug is available in injection only, and that it’s given to patients already on insulin. It’s new, and there is very little experience with it, but it may prove to be a God-send for some patients. Let’s give it a chance to prove itself.

 


Rimonabant – Too Good To Be True

More information is made available about this fascinating agent which is a marijuana-receptor blocker (in the brain). Apparently, there are already three studies showing significant results. These studies were conducted over a one year and a two year periods, and both showed some weight drop, shrinking of abdominal circumference, and reduction of some of the features of the Metabolic Syndrome. The drug is not available yet, but with this track record, sure to be approved.

 


Alzheimer’s Disease and Insulin

The most recent hypothesis about Alzheimer’s Disease (AD) involves insulin. It has been known for many decades that insulin is present and produced by the brain. What has not been reported is that insulin is significantly reduced in brains of patients with AD. In addition, receptors to insulin are also deficient. This may simply be directly related to the loss of brain tissue, however the scientists that discovered this phenomenon would like us to think that there is more to it than just a simple relationship - maybe in the future we'll be able to somehow introduce insulin into the central nervous system.

 


Byetta

And yet another new diabetic drug.. The FDA has just approved a new drug for diabetics with type 2, who are not optimally controlled. The drug is a protein which is a synthetic version of a protein that is found in the saliva of the Gila monster! This “monster” is actually a lizard that lives in the Southwestern part of the US. Don’t ask me how this was originally discovered (I’ll try to look into it), but apparently this protein is identical to a hormone called GLP-1, which is normally secreted by the stomach after food ingestion. This protein is part of a group of hormones called incretins, with a main role of augmenting insulin secretion. The up-side is that they don’t cause hypoglycemia, however the down-side is that they need to be injected twice daily – Ouch!

 


No Diabetes Post Gastric Bypass

Morbidly obese individuals with diabetes who undergo a gastric bypass procedure – cutting out a portion of the stomach – experience a very quick remission of their diabetes. Within days to weeks most (84%) of patients no longer need their diabetic medications, and come up with normal glucose levels on their glucometers. Obviously, that kind of response cannot be attributed to weight loss. Ghrelin, which is a hormone secreted by the stomach and the proximal small intestine, has been implicated. It is, in fact, the only known circulating appetite stimulant. Post gastric bypass, Ghrelin levels stay depressed. In addition to appetite suppression, Ghrelin also has actions which are diabetic-like. Eliminating Gherlin, therefore, probably accounts for the diabetic “remission” noticed.

 

 

Gadgets

An innovative company has come up with a kea-chain USB hard drive which is capable of containing all medical information related to an individual’s medical history. In addition to written data, this can also contain x-ray data, as well as other forms of imaging. Data can be up-dated, and when patient arrives in the emergency room, all that needs to be done is plug the little hard drive in a computer and instantaneously access the data. This may prove to be standard procedure in the not too distant future. I’m looking for a donation, so we can start this at the Litvin Center for Diabetes.
