Guest guest Posted July 10, 2010 Report Share Posted July 10, 2010 1. %% NYTimes 6/28/10 The Claim: Diabetes Makes You Sensitive to Heat THE FACTS Summer can be uncomfortable for anyone. But for people with DM, the heat and humidity can be particularly hazardous. One of the complications of T1 and T2 is an impaired ability to adjust to rises in temperature, which can cause dangerous increases in body temperature. The underlying problem, nerve damage , occurs in 60-70% of Americans with DM; it can affect nearly every organ in the body, including sweat glands. When nerve damage keeps the sweat glands from working properly, the body fails to cool down as the mercury rises. One small study compared diabetic patients and a group of healthy control subjects. As temperatures rose, the control subjects¡¯ perspiration rates increased proportionately; their core temperatures stayed constant. ¡°For subjects with DM, sweat seemed to plateau irrespective of an alarming rise in core temperature,¡± research shows that DM patients have higher rates of adverse events - like hospitalizations, dehydration and death - in the heat. Yet a survey found many were unaware of the greater risk and the need for special precautions. THE BOTTOM LINE People with diabetes are particularly vulnerable to hot weather. 2.%% ADA 70;REACH for Metformin to Reduce Deaths in Patients With Diabetes & Atherothrombosis 7/1/10 In patients with DM and atherothrombosis, the use of metformin was associated with a 24% reduction in all-cause mortality after 2yr Fup.[20,000 DM pts in REACH registry] who had cerebrovascular disease, coronary disease, claudication . plus at least 3 otherothrombotic risk factors, including current smoking, hypercholesterolemia, DM nephropathy, hypertension,. and the presence of at least 1 carotid plaque. 3.%% Nature news avandia 6/28/10 Evidence mounts against diabetes drug Studies continue to find heart-attack risk. Avandia, used to treat T2DM, has attracted controversy. Patients who take Avandia are more likely to have a stroke or heart failure, or die, than those who take a rival drug, a survey of more than 200,000 insurance records has revealed.. The finding, is the latest salvo in a continuing battle over Avandia (rosiglitazone). The possible health risks of Avandia were brought to light in 2007, when a meta-analysis by Nissen, a cardiologist at the Cleveland Clinic suggested that the drug could cause heart attacks . This is a particular concern given that diabetics already have a high risk of CV disease...The US Senate launched an investigation and concluded that GSK was aware of the adverse effects of Avandia well before the risks were made public. In a new paper Nissen and statistician Kathy Wolski, repeat their 2007 meta- analysis, incorporating new clinical-trial data ...They again found that Avandia boosts heart-attack risk - by up to 39%. Meanwhile, in JAMA, Graham, a drug-safety researcher at FDA et al; analysed the insurance records of 227,571 pts treated with either Avandia or Actos (pioglitazone) a similar drug and found that patients taking Avandia were 18% more likely to suffer from a stroke, heart failure, heart attack or death than those on Actos. " The study by Graham et al . is very convincing, " says C.de Vries, an epidemiologist at the U. of Bath, UK. " I can't fault it, and I suspect it might be the nail in the coffin for rosiglitazone. " 4.%% ADA 70; New Class of Drug for T2DM Acts Independent of Insulin 6/28/10 - Dapagliflozin, improves glycemic control by reducing renal glucose reabsorption, [phase 3 study.] Given with metformin, dapagliflozin represents a new therapeutic option for the treatment of T2 patients who have inadequate glycemic control with metformin alone. Dapagliflozin,a selective sodium-glucose cotransporter-2 inhibitor, prevents reabsorption of glucose in the kidneys and promotes the excretion of glucose in the urine. It thereby reduces high levels of blood glucose without affecting insulin- dependent systems. " Because [of this] mechanism, it should be suitable for use at any time during the duration of the disease process, and should be compatible with ..any of the other therapies that we have available at the moment. " [534 T2 adults randomly assigned to 1of 3 doses of dapagliflozin or placebo orally once daily, in addition to their prestudy metformin dose. Results - mean HbA1c decreased by -0.30% in the placebo group compared with 0.84% in the dapagliflozin 10 mg group. Hypoglycemia was reported at similar frequency in both groups. However, symptoms of genital infections were more common in the dapagliflozin groups - in 8-13% of individuals compared with in 5% of those in the placebo group. " This is likely to reflect the extra glucose that is eliminated in the urine, " .. Mean weight loss was 0.9 kg [1.98 lb] per person in the placebo group compared with 2.9 kg in the dapagliflozin 10 mg group. study -supported by Bristol-Myers Squibb and AstraZeneca. 5.%% MW Mixing Insulin Aspart and Detemir in a Single Syringe Lets Children Avoid Extra Shots (Reuters Health) Jun 21 - In children with T1DM, mixing insulin aspart and detemir in the same syringe has the same effect on blood sugar levels as giving the injections separately, investigators report. Not surprisingly, pain from injections is a big obstacle to managing DM in children. Detemir should ideally be taken twice a day and aspart must be taken with at least all 3 major meals, resulting in 5 injections given separately. " With the results from our trial, we will be able to reduce insulin injections by 2/day and that equals a reduction of 60 injections/month without compromising glucose levels, " said senior author. [14 children with T1]Each child wore a continuous glucose monitoring device, and the team analyzed data for the last 72 hours of each study period.] There was no statistically significant difference in glucose amplitude or frequency of mild hypoglycemia.Diabetes Care 2010. 6.%% MW Islet Transplantation a Decade Later and Strategies for Filling a Half-full Glass 6/23/10 Diabetes. 2010;59(6): Alloislet transplantation for the treatment of T1DM enjoyed highly favorable status in the first half of the last decade but declined in favor during the second half. I will briefly review the literature published in this area from 2000 - 2010 for the purposes of extracting lessons we have learned, considering whether the procedure should be deemed a partial success or a partial failure, and offering strategies to improve alloislet transplantation outcomes in the future. In the end, I hope to strike a positive note about where this procedure is going, and how it will be applied to establish insulin independence in patients with T1... Bridge to the Future A valid argument against islet transplantation as a treatment for T1 is the undeniable arithmetic that not nearly enough pancreas donors exist to treat patients with T1, let alone all people with T1 & T2. Does this mean we have been wasting our time and resources by studying islet transplantation? I don't believe so. There will always be DM patients who need ©¬-cell replacement by transplantation of islets or the pancreas. One group of patients comprises those with rapid development of secondary complications despite optimal medical care. Another group is made up of patients with the neurological disorder of autonomic insufficiency, which is accompanied by a 50% death rate within 5 years of diagnosis. They are clearly candidates because successful pancreas transplantation converts this death rate from 50 to 10%. One must also consider what the future may bring. Our experiences with islet transplantation have taught us lessons that will be important for the use of ©¬-cell surrogates, be they stem cell derivatives or modified cell lines. We have learned about culturing cells, isolating islets and ©¬-cells, identifying safe and physiological sites for transplantation, avoiding immunosuppressive drugs that are toxic to ©¬-cells, meeting environmental needs for physiological a-cell function, and selecting appropriate patients for ©¬- cell replacement. This is important information to use as we continue to meet the challenge of creating better means of controlling hyperglycemia and avoiding its complications. We just need to continue on with new scientific work until the transplantation glass is successfully filled.

Traditionally, the approach is to initiate monotherapy first, followed by combination therapy that targets 2 main defects in T2. Repaglinide [prandin], a rapidly acting insulin secretagog, stimulates insulin secretion via closure of ATP-dependent potassium channels on the cell membrane of ©¬-cells. Repaglinide is ideally used at mealtime to reduce postprandial [after meal] glucose levels, thus lowering the 24-h blood glucose profile and improving HbA1c levels. Metformin is an insulin sensitizer that effectively acts against insulin resistance, one of the predominant metabolic defects in T2. Combo R+M is indicated as an adjunct to diet and exercise to improve glycemic control in adults with T2. When monotherapy with oral antidiabetic agents fails, Combo R+M has been demonstrated to be safe and effective in the treatment of T2DM.

The cause of DGF .. It is hypothesized that ischemia-reperfusion injury during transplantation procedure causes a cascade of molecular events that eventually leads to apoptosis, inflammation, and endothelial injury, resulting in organ dysfunction and nephron [kidney cell] loss.further investigation of intensive glucose control in both the diabetic kidney donor and the recipient during the perioperativeperiod may be warranted to determine the effect of glucose control on initial graft function. 10.%% Hip Fractures Linked to Thiazolidinedione [TZ] Use Higher Than Expected in Men 6/29/10 ADA 70 TZs increase fracture risk, not just in women,but in men, particularly middle-aged men. Moreover, these fractures are not limited to distal sites like the feet and hands, but also occur in the hip. The team looked at fracture requiring hospitalization in T2.[212,977 people] They found that exposure to either rosiglitazone or pioglitazone was associated with a 1.7-fold increase in the overall fracture rate in women, and a 1.3- fold increase in men. Male TZ users had a 2-fold risk for hip fracture. " I would point out that the risk in men is actually not in older men, it's more in middle- aged men between 55 - 65 yrs, " 11.%% MNTD 12 New Genes Linked To Type 2 Diabetes 6/28/10 This brings the total number of genes known to be associated with the condition to 38. An international consortium of scientists compared the DNA of over 8,000 people with T2s with almost 40,000 people without the condition at almost 2.5 million locations across the genome. " This is strong research and adds to our knowledge of the genes that increase the risk of developing T2. As we continue to add more pieces to the jigsaw, our greater understanding of the genetics behind T2 could lead to new avenues of research into prevention and improving treatments.. 12.%% ADA 70; Women With T1DM Receive No Heart Benefit From Omega-3 6/28/10 Consuming higher amounts of omega-3 fatty acids does not appear to lower heart disease risk for women with T1. Omega-3 fatty acids, primarily found in fish, promote heart health by preventing buildup of cholesterol in the arteries. Little is known about the effect of consuming omega-3 in people with T1DM, who are at much greater risk for heart disease. The incidence of heart disease was lowest in men who consumed the highest quantities of omega-3 - more than 0.2 grams per day. Women who consumed similar amounts did not have lower rates of heart disease. " Although omega-3 is typically associated with decreased risk for CV disease, this may not be the case for women with T1, " said the lead author. ¡°.. we shouldn't assume men and women with T1 are the same. " 13.%% MNTD Too Much HDL May Be Harmful To Women With T1DM 6/28/10 Elevated blood levels of high-density lipoprotein (HDL) or " good " cholesterol, typically thought to protect against heart disease, may do the opposite in women with T1 [658 men & women HDL cholesterol is known as " good " cholesterol because it helps prevent arteries from becoming clogged. High levels of HDL over 60mg per deciliter (mg/dL), generally protect against heart disease, while low levels (less than 40 for men and less than 50 for women) increase risk. the incidence of heart disease increased in both men & women with DM who had lower levels of HDL - below 47.5 mg/dL. For men, as levels of HDL increased, their incidence of heart disease decreased. The same was found for women, except in those with very high levels of HDL (over 80 mg/dL) whose incidence of heart disease increased substantially. " We need to examine this relationship further, but our study suggests that too much of a good thing may not always offer protection and may even be harmful for women with T1. 14.%% MNTD Explaining Complications Associated With Diabetes 6/25/10 New research uncovers a molecular mechanism that links diabetes with an increased risk of CV problems and sudden cardiac death. It finds that high blood sugar prevents vital communication between the brain and the autonomic nervous system, which controls many involuntary activities in the body. " Diseases, such as DM, that disturb the function of the autonomic nervous system cause a wide range of abnormalities that include poor control of BP, cardiac arrhythmias, and digestive problems, " explains senior study author. The team examined the transmission of electrical signals from the brain to autonomic neurons in a mouse model of DM. The brain communicates with autonomic neurons at synapses, a small gap between 2 nerve cells where electrical signals from one nerve cell are sent to the next by chemical neurotransmitters. " In healthy people, synaptic transmission in the autonomic nervous system is strong and stable; however, if synapses on these neurons malfunction due to some disease process, the link between the nervous system and the periphery becomes disrupted, " The team discovered that high blood sugar causes such a disruption in synaptic transmission which is apparent as early as 1 week after the onset of DM becoming more severe over time. " 15.%% MNTD Poor Control Of Diabetes May Be Linked To Low Vitamin D 6/22/10 Vit D deficiency is highly prevalent in patients with T2 and may be associated with poor blood sugar control [124pts with T2; divided into [quarter groups] based on vit D level. the team found an inverse relationship between the patients' blood levels of vit D and their hemoglobin A1c value, a measure of blood sugar control over the past several months. Lower vit D levels were discovered in patients with higher average blood sugars. Compared with whites, blacks had a higher average A1c and lower average vit D level.. screening & vit D supplementation as part of routine primary care may improve health outcomes of this highly prevalent condition, " 16.%% MNTD 6/28/10 Resveratrol - found in red wine, grapes, blueberries, peanuts and other plants - stops out-of-control blood vessel growth in the eye. The discovery has implications for preserving vision in eye diseases such as diabetic retinopathy and AMD. Working with mouse retinas, the team found that resveratrol can inhibit angiogenesis - when the mice were given resveratrol, the abnormal blood vessels began to disappear. Examining the blood- vessel cells they found a pathway - known as a eukaryotic elongation factor- 2 kinase (eEF2) regulated pathway, that was responsible for the compound's protective effects. " We have identified a novel pathway that could become a new target for therapies, and we believe the pathway may be involved both in age-related eye disease and in other diseases where angiogenesis plays a destructive role. " said the lead author. In mice, resveratrol was effective both at preventing new blood vessels and at eliminating abnormal blood vessels that already had begun to develop...If resveratrol therapy is tried in people with eye disease, it would need to be given in pill form because of the high doses required, 17.%% JH Microalbuminuria: What It Means 7/1/10 Both elevated blood glucose and high BP damage blood vessels in the kidneys, just as they harm blood vessels throughout the body-- a vicious cycle may develop. As your kidneys weaken, BP often rises, and that in itself damages the kidneys further. Diabetic nephropathy or kidney disease develops slowly over the course of years. Long before any physical manifestations are present, kidney disease leaves a clue that allows doctors to detect it early: microalbuminuria, or small quantities of the protein albumin in the urine. When elevated blood glucose and BP damage blood vessels in the kidneys' filters, protein starts to leak into the urine. At first, the leaks are tiny, so only small amounts of proteins like albumin slip through. At a later stage, the amount of protein in the urine (proteinuria), increases. You should be screened each year for microalbuminuria if you have T2 or have had T1 for at least 5 years. Screening can be done any time of day with just one sample of urine. What about blood tests? The fact is that no abnormalities show up in the blood until kidney disease has progressed beyond micro albuminuria. .. 18.%% NIH News 6/29 /10 #1. Aiming for Near-normal Blood Sugar Did Not Delay Combined Risk of Diabetic Damage for People with Long- standing Diabetes, In people with longstanding T2DM who are at high risk for heart attack and stroke, lowering blood sugar to near-normal levels did not delay the combined risk of DM damage to kidneys,eyes, or nerves, but did delay several other signs of diabetic damage. The intensive glucose treatment was compared with standard glucose control. Over time, DM damages the small blood vessels of the eyes, nerves, kidneys and other organs, leading to pain and disability. Heart disease due to damaged large blood vessels is a major cause of death in persons with T2. The longer a person has DM, the greater the chances of serious complications, including vision loss - blindness, foot ulcers - amputations, kidney disease -kidney failure, and heart disease - stroke. " In these ACCORD participants with established T2 and additional risk factors for CV disease, intensive lowering of blood glucose reduced some markers of eye, nerve and kidney disease compared with standard glucose control, but the groups did not differ in the rate of progression to kidney failure, nerve disease, and major vision loss, " said lead author. [10,000 adults withT2] " Although increasing treatment to try to achieve near-normal blood sugar provides some benefit, clinicians and patients should note that this treatment strategy also potentially increases the risk of adverse effects in patients with additional risk factors for heart disease, such as those studied in ACCORD. " #2. ACCORD Eye Study Finds Intensive Blood Sugar Control or Combination Lipid Therapy Decrease Diabetic Eye Disease Progression: In high-risk adults with T2, researchers have found that 2 therapies may slow the progression of diabetic retinopathy [DR], an eye disease that is the leading cause of vision loss in working-age Americans. Intensive blood sugar control [bSC] reduced the progression of DR compared with standard BSC, and combination lipid therapy with a fibrate & statin also reduced disease progression compared with statin therapy alone. However, intensive BP provided no additional benefit compared with standard BP control. ACCORD Eye Study [subset of 2,856 subjects]. the team analyzed the effects of the treatment strategies on blood vessels in the eye by identifying DR progression over 4 yrs. Diabetic retinopathy is a disease in which blood vessels in the eye's light-sensitive retinal tissue are damaged by DM. Blood vessels can begin to leak, causing swelling in the retina, and abnormal new blood vessels can develop, both causing vision loss. Compared with standard BSC, intensive control decreased the progression of DR by 10.4 to 7.3 %. Those in the intensive control group had a median blood sugar level of 6.4 % hemoglobin A1c-a level close to values in people without DM. The standard BSC group maintained a median level of 7.5%. " Previous clinical trials have shown the beneficial effects of intensive BSC on slowing the progression of DR with T1 or newly diagnosed T2, " said NEI director A. Sieving " The ACCORD Eye Study expands these findings to a larger population of adults who had T2 for an average of 10 years, and demonstrates that the eye benefits from the reduction of glucose below previously established levels.

[23,000 women] Those who did not have GDM but who were obese had a 13.6% increase in risk for macrosomia (a child weighing [8lb 13oz] or more at birth) than nonobese women. The combination of obesity and GDM was associated with a 20.2% increase in risk for macrosomia... 20.%% ADA 70: Dual SGLT Inhibitor Causes Rapid Drop in Glucose Values 6/29/10 An investigational oral antidiabetic agent - a dual sodium-glucose transporter (SGLT)-2/SGLT-1 inhibitor- showed significant improvement in (HbA1c), fasting plasma glucose (FPG), and oral glucose tolerance testing (OGTT) levels over 4 weeks in patients with T2.In a phase 2a trial of LX4211 in 36 patients, mean HbA1c levels declined from baseline by 1.5% among patients treated with a 150 mg dose of the drug compared with a 0.49% drop for patients treated with placebo. Despite the increased urinary glucose secretion in patients in the LX4211 groups, there were no treatment- related urinary tract or genital infections, the authors reported. 21.%% Long-Term Cardiac Risk: Higher With Diabetes, or a First MI? Jun 25 - If you compare diabetics without heart disease, and primary heart attack patients without DM, which group will have the higher 10-year rate of major coronary events? The one with the primary heart attacks, new research shows. In a study in a Mediterranean group, pts with T2 had a significantly lower long-term incidence of unstable angina and fatal or nonfatal myocardial infarction (MI) compared to nondiabetics who'd had a primary MI. [2260 T2 diabetics; 2150 MI pts] 22.%% ADA 70: Standard CV Risk Factors Don't Explain the Doubling of Vascular Disease Risk in Diabetes 7/1/10- Diabetes is a risk factor not only for ischemic vascular diseases such as MI and ischemic stroke, it also seems to pose a significant risk across the spectrum of different forms of vascular disease, including hemorrhagic stroke, suggests a meta-analysis encompassing almost 700,000 patients Moreover, it showed that the elevated risks were largely independent of conventional CV risk factors, suggesting that DM must be raising vascular risk through less familiar mechanisms. . " very little of the excess CV risk associated with DM is explained by obesity, BP, lipids, inflammatory markers, or renal function. " the presenter said " That means there are yet- to-be discovered pathways that better explain why people with diabetes are at increased CV risk, 23.%% Ophth 117,7 July 2010 Sustained Ocular Delivery of Fluocinolone Acetonide (FA)by an Intravitreal Insert Purpose - compare Iluvien intravitreal inserts that release 0.2 or 0.5 ¥ìg/day of e (FA) in patients with diabetic macular edema (DME) Prospective, randomized, interventional, [37pts] Conclusions -[these]inserts provide excellent sustained intraocular release of FA for =1 year.

" Think of genetics as the loaded gun and the environment as pulling the trigger. " ... if you put a person who has a genetic predisposition for DMs in an environment that promotes weight gain, the patient will most likely become diabetic. Conversely, if you put that same person .. where it is difficult to gain weight, then the DM may never manifest. ..To explain the relationship between obesity and diabetes, one must first understand how humans gain weight. One of the easier ways to think of obesity and the accumulation of fat cells is to view fat gain as central or peripheral. Peripheral fat gain refers to subcutaneous fat that is easily measurable by grabbing the fat just under the skin. Peripheral fat is relatively benign in metabolic terms; much of its deleterious effects are structural..[such as] increased load on the weight-bearing joints.. Central or visceral fat, is deep in the abdomen and the chest and is found around or sometimes in the organs. An example- the presence of omental fat around the small intestines and visceral organs, as in " fatty liver " disease. Central fat is also associated with insulin resistance and metabolic syndrome. In the 1960s, a biochemist reported on the competition between fat and glucose for entry into the human cell- how a cell has its choice of energy to run the cell's functions. If times are lean - not much food is available, very little insulin is needed to transport glucose into cells. If food is abundant, however, the cell can function on fatty acids or glucose. The more fatty acids are floating around in the blood stream, the more insulin is needed to get these fatty acids and glucose into cells. Thus, as the body makes more visceral fat, there is an abundance of fatty acids in the blood, and competition with glucose for entry into the cell, in turn, increases the amount of insulin needed. This is called insulin resistance because more insulin is needed to transport the same amount of glucose into a cell. .. as fatty acid levels rise with weight gain, more insulin is needed to drive in fatty acids & glucose into cells. .. the body can produce only so much insulin; eventually the pancreas cannot keep up with these larger demands to produce insulin. This is the first step toward diabetes -- the blood glucose will start to increase because of a combination of insulin resistance and inability to make enough insulin. As this state of central weight gain and insulin resistance sets in, other cardiometabolic [CM] factors begin to emerge. Lipid changes known as dyslipidemia begin to occur, and one will see a drop in high- density lipoprotein (HDL) cholesterol levels and an increase in triglyceride levels. At this point BP can begin to rise. This move of CM risk factors in the wrong direction is commonly known as metabolic syndrome .With normal dieting one loses weight that is a combination of visceral and peripheral fat. [which] will improve blood glucose, HDL and triglyceride levels. . a weight loss as little as 5%-10% will improve DM measures and even reverse borderline blood glucose levels to within the normal range.. it is not surprising that more T2 is seen in men and Asians of both sexes. .since [this group] gains their weight centrally - not peripherally. " Asian " [here = ]eastern Asians (eg, Chinese, Japanese) and western Asians ( Indians from India)... 26.%% ADA 70;Vitamins C and E a Bust at Preventing Preeclampsia in Diabetic Women 7/2/10 - Vitamins C and E get an F+ when it comes to preventing preeclampsia in women with T1DM Neither vit C nor E supplements were better than placebo at preventing preeclampsia in DMc women. Vitamin supplementation also failed to reduce the frequency of gestational hypertension or low birth weight..however, we did not observe any adverse maternal or neonatal outcomes, and in.. subgroup analyses, the risk for preeclampsia was significantly reduced in women with low antioxidant status at baseline randomized to vitamin treatment, compared with [those] assigned to placebo, " 27.%% ADA 70:Diabetic Instructors Help Neighbors Lose Weight, Improve Glucose Profiles 7/2/10 A community-based health intervention styled after the Diabetes Prevention Program (DPP) helped adults at risk for DM lose significant amounts of weight and pull their belts in by a notch or 2, [301 subjects with Prediabetes] " Our reduction in glucose of 4 mg/dL is comparable to the DPP and to the Finnish DM Prevention Study. Those differences were associated with about a 50% reduction in the incidence of DM, so we believe this is a clinically meaningful reduction in glucose. " I think we need as many outlets for DM education and prevention as we can find, " the presenter said.The program is delivered through local diabetes care centers by registered dietitians and community health workers, who are diabetes patients identified as good candidates for training and group leadership. 28.%% Switching to Once-daily Liraglutide from Twice-daily Exenatide Further Improves Glycemic Control in Patients with T2DM using Oral Agents 6/29/10; Diabetes Care. 2010;33(6) Conclusions Conversion from exenatide to liraglutide is well tolerated and provides additional glycemic control and cardiometabolic benefits...[389 pts] 29.%% Cinnamon and Prickly Pear Cactus -- Should They Be Part of a T2DM Diet? 6/30/10 Case Presentation Mr. is an English- speaking Latino patient The patient is unhappy about the suggestion to add a second antidiabetic medication because he does not wish to be medication dependent. He has been advised by his family to use nopal (prickly pear cactus) and to add cinnamon and fenugreek to his food. A review of 108 trials of herbs and dietary supplements used for glycemic control in 4565 patients with DM or impaired glucose tolerance found that the supplements seemed to be generally safe but needed further study. Another review of herbals used in Mexico examined therapies preferred by 573 patients with T2. nopal was used most often. The exact mode of action is not known, although nopal has high fiber and may have an insulin- sensitizing effect... The broiled stems are traditionally used for their hypoglycemic effect, which is seen 3-4 hours after ingestion and can persist for up to 6hr. When 85 g of nopal was added to typical Mexican breakfasts, it reduced glucose levels for several hours and favorably altered the glycemic index of test breakfasts [36pts with T2 who were receiving glibenclamide, metformin, or both]. This team proposed that nopal be used to supplement dietary approaches to DM care in a culturally effective way for Mexicans. The theoretical concern with use of nopal is interaction with antidiabetic medication, with consequent hypoglycemia. Patients who use nopal regularly should be advised to monitor blood glucose closely. .. Gymnema extract,.. overall, evidence is insufficient for its efficacy in DM treatment. Gymnema should be used with caution in DM patients. Cinnamon., Animal and in vitro studies have indicated that cinnamon may mimic the effects of insulin, act as an insulin sensitizer, and improve cellular glucose uptake and glycogen synthesis. Clinical studies are small and have produced contradictory results. In the most recent randomized controlled trial, of 109 patients with T2, cinnamon capsules at a dose of 1 g daily for 90 days lowered A1c by 0.83% The team recommended cinnamon as an adjunct to DM care for patients with an A1c greater than 7.0%.The dose of cinnamon for T2 is typically 1- 6 g daily; 1 teaspoon contains 4.75 g. This dose is considered to be safe for up to 4 months. Of note, cinnamon contains coumarin; ingestion of large amounts is therefore not recommended. Liver toxicity in animal models has also been reported..fenugreek. In one study, 10 patients with T1 The fenugreek diet significantly reduced fasting blood glucose and improved glucose tolerance test results.; there is a theoretical risk for interaction with warfarin, which entails risk for bleeding. Of the CAM therapies that Mr. has asked about, nopal and cinnamon seem to hold the most promise for glucose control in persons with A1c levels greater than 7.0%, and both would be easy to introduce into his meals.
