Kelly Close: State Of Diabetes Treatment, Companies In The Sector And Challenges Patients Face

As president and founder of Close Concerns, a healthcare information firm focused on diabetes and obesity, Kelly Close says her passion comes from her extensive professional work as well as her personal experience, contracting Type 1 diabetes 25 years ago. Prior to starting Close Concerns, she worked in the financial sector, including stints as an analyst at Goldman Sachs, as an equity research analyst covering medical technology at Merrill Lynch, and as a management consultant at McKinsey & Co., where a majority of her work focused on for-profit and nonprofit healthcare organizations. Ms. Close and her colleagues at Close Concerns attend more than 40 scientific, regulatory and economic conferences around the world focused on diabetes and obesity, analyze key medical literature, and cover more than 50 private and public companies and nonprofit organizations. Recognized as an expert on the diabetes and obesity markets, and as a frequent speaker on the public health implications of these conditions, Ms. Close is a tireless advocate for patients. In this interview Ms. Close discusses the state of the industry and challenges that patients face.

Can you describe your mission?

It's to make everyone - researchers, clinicians, scientists, companies, and patients - smarter about diabetes and obesity in order to improve patient outcomes. Our team studies new research, and we synthesize news and insights on therapies and technologies on diabetes and obesity.

Why diabetes and obesity?

I have a deep personal interest in diabetes, so my goal once on Wall Street was always to narrow my focus from writing about medical technology (and helping biotech and pharma analysts) to working on all parts of diabetes, in a way you can't do as an analyst. In other words, I wanted to work on medical devices, pharmaceuticals and biotech all at once. Then, there's obesity. Well, the association between obesity and Type 2 diabetes has long been recognized. You can't separate the two; they are inextricably linked. Cases of diabetes have risen nearly tenfold since I was diagnosed in 1986. There were about 30 million people globally with diabetes then. Today there are 30 million in the US alone, with nearly 400 million globally, with much of the trend due to the increasing prevalence of risk factors, including obesity. And around 80% of Type 2 diabetics are either overweight or obese.

Tell me a little about your information services.

Our first publication in 2003 was Diabetes Close Up, where we simply updated news about different companies and conferences that we attended. In 2007, we started Closer Look, which goes out several times a week - sometimes daily - and the two publications now keep researchers and members of the industry abreast of scientific breakthroughs. Our online newsletter, diaTribe, began in 2005 as a free service, with the goal of keeping patients up-to-date on the latest research, products, and advice from the diabetes scientific community. And through dQ&A, our sister company that we started in 2009, we offer corporate clients market research and consulting services.

When I began Close Concerns, 18 million Americans had diabetes, and the sector had $14-billion in revenue. Today, in 2013, the industry has expanded to more than $40-billion, and there's widespread agreement that diabetes and obesity have turned into global epidemics that cannot be sustained. We absolutely must change diabetes management to make sure patient treatment, therapy and advice are optimized from the time of diagnosis throughout the entire spectrum of the condition.

What are some of the challenges you see today?

It's never been a more challenging time in terms of reimbursement and patient access to medicines and healthcare professionals. In much of the world, patients still don't have access to insulin or other medications. On the other hand, extensive progress has been made on the actual tools that are available. Access is so much more challenging, however, regardless of whether we are talking first world or third world. Doctors, for example, may reach a common diagnosis of diabetes, but the pressure they face with patients is prescribing the correct treatment, determining what patients will adhere to, and what insurance will cover. And that is patients with insurance. Medicare is missing the forest for the trees on some of its new reimbursement decisions in the U.S., and globally, patients certainly are not getting the treatment, therapy and advice they need to keep them healthy. Finally, there are major issues with patient advocacy - it must be much stronger, but lingering stigmas about this disease continue.

What about treatment challenges today?

The positives are that medications have improved dramatically and the technology exists to see which medications work and don't work. Today, the emphasis is on early, optimized treatments, given that nearly 50% of Type 2 diabetics are not at their glycemic target even here in the U.S. Because there are many more oral medications available before a patient is moved to insulin, the best healthcare providers no longer take a wait-and-see approach if a patient can't control their HbA1c (a three-month average measurement of glucose in the blood); they prescribe a new medication, often a combination of drugs. Another bonus of having many more drugs available today is that treatments can be customized for a patient, which is the promise of personalized medicine - again, this varies with access. Adherence is such a challenge that it will be great to move several medications to one - one pill and one co-pay for patients in the U.S. and, ideally, better adherence. Adherence studies have been very hard to do historically, and this is one of the biggest challenges ever. Historically, taking insulin has also been very challenging. We hope this will become easier all over the globe and that the stigma of taking insulin will begin to dissipate.

Can you talk about emerging trends in technology?

Absolutely. One really dispiriting area is that in the U.S., we see pricing pressure and reduced access to good technology. This is driven by CMS wanting to save money, and while it may sound good for patients, we worry that it winds up resulting in less product innovation, fewer funds going to R&D, less customer education and customer service, etc. We're seeing better insulin pumps coming out all the time, combined with continuous glucose monitoring. Monitors used to be inaccurate and unreliable, but the technology is much improved and readings from meters are getting closer to readings from actual blood tests. The data we've seen on the Dexcom (NASDAQ:DXCM) G4 Platinum, for example, is better than some glucose monitors. But lots of people still dose their insulin based on counting carbohydrates, and there are lots of reasons why scores can be incorrect.

What's the status of oral insulin?

I thought we'd never see it because there are so many challenges associated with it. But I'm much more optimistic than ever before. It's still very early stage, but Novo Nordisk (NYSE:NVO) is working on it, and that's a very positive sign. We're beginning to see positive data come out, and the flat truth is just that we need more alternatives to injected insulin. MannKind (NASDAQ:MNKD) and its inhaled insulin therapy, AFREZZA, has driven our optimism. It has taken a long time to get to a second-generation inhaled insulin that is practical, easy to use and effective, but the data, especially that on hypoglycemia, look good.

What are your thoughts on the potential of GLP-1?

This is the first new class of therapeutics to come to market that doesn't cause hypoglycemia and doesn't cause weight gain. That's awesome because insulin has had all of those problems. Novo Nordisk's GLP-1 reached $1 billion in sales a year before the company expected - again, this has been easier for patients to take and provides a valuable step between traditional orals and insulin. What's really compelling in combination therapy is the potential for GLP-1 plus insulin. SGLT2 inhibitors are also interesting - we'll definitely see fixed-dose combinations here too, eventually. Earlier this year, the FDA approved Johnson & Johnson's (NYSE:JNJ) SGLT2 inhibitor, Invokana, which has efficacy closer to GLP-1 and, judging by the early data, a safety profile closer to DPP-4 inhibitors, which have the best side-effect profile of all. We'll see - we'll be eager to watch the emerging data.

Have you seen any interesting new data in GLP-1 research?

Transition Therapeutics (NASDAQ:TTHI; TSX:TTH) announced some really exciting data in the summer for TT401, which targets GLP-1 and glucagon receptors for obese diabetic patients and may provide clinical effects superior to those of GLP-1 agonists. (BT note: the proof-of-concept data prompted partner Eli Lilly (NYSE:LLY) to acquire an option on the drug candidate to complete clinical development.) We're also really looking forward to seeing more data on iDegLira, which is the combination of next-generation insulin degludec, which the FDA recently delayed, surprisingly, and on Victoza, from Novo Nordisk. BMS/AZ is also working on a Bydureon pen as well as a once-monthly formulation, and Intarcia is working on implantable GLP-1. There's no doubt this class will continue to grow as the applications become even easier and as the efficacy and safety data continue to grow.

Dementia risk score for people with diabetes
not yet ratednot yet rated

Scientists have created a simple scoring system that will allow clinicians to predict whether older people with type 2 diabetes are at risk of developing dementia, according to a study published in The Lancet Diabetes and Endocrinology.

Researchers from the Kaiser Permanente Division of Research in California say the new system, called the "diabetes-specific dementia risk score" (DSDRS), will mean doctors can closely monitor patients with type 2 diabetes who are at highest risk of dementia and enable early treatment to be given.

For the study, the research team analyzed medical records of 29,961 Kaiser Permanente patients over the age of 60 who had type 2 diabetes.

The researchers looked at whether the patients were diagnosed with dementia within the 10-year follow-up period. The analysis revealed that 17% of patients developed dementia during this time.

They built the DSDRS model with 45 candidate risk factors for dementia. Using "sophisticated statistical methods," the researchers looked at patients' medical records to determine the risk factors that most strongly predicted the onset of dementia within 10 years.

The following were identified as the most important predictive factors:

The scoring system can divide patients into one of 14 categories. The lowest score is -1, which indicates the lowest risk of dementia, while the highest scores are between 12 and 19.

By using the diabetes-specific dementia risk score, results showed that, compared with those who had the lowest scores, patients with the highest were 37 times more likely to develop dementia within 10 years.

Additionally, patients with the highest scores developed dementia faster than those with the lowest.

The researchers tested the scoring system against a large group of people with type 2 diabetes who were unrelated to the study and found that it accurately predicted their risk of developing dementia.

Dr. Rachel Whitmer from Kaiser Permenante says:

"Unfortunately, there is an epidemic of both type 2 diabetes and dementia, and the link between these two illnesses portends a possible public health crisis."

"Our model shows that in two large populations of patients with type 2 diabetes a combination of diabetes-associated complications, education, and age is highly predictive of the likelihood of dementia within the next decade."

The study authors say that this is the first time scoring systems have been used to specifically predict dementia in patients with type 2 diabetes.

They add that the scoring system would prove beneficial to doctors in predicting the onset of dementia in type 2 diabetes patients, as it does not rely on expensive, complicated brain imaging or cognitive testing.

"Early detection of patients with type 2 diabetes who are at increased risk of dementia could help to develop and target preventive treatment," says Dr. Whitmer.

"Our scoring system has the potential to change clinical care by giving clinicians a simple and accurate way of predicting the risk of dementia in older people with type 2 diabetes."

But the study authors note that there are plans to conduct a second stage into the scoring system, which may involve some use of cognitive testing in order to improve accuracy.

In a comment piece following the study, Dr. Anna-Maija Tolppanen of the Center for Comparative Effectiveness and Patient Safety in Finland, says that although the diabetes-specific dementia risk score (DSDRS) could be beneficial for clinicians in determining dementia risk, the system may not be so useful in selecting patients for drug trials.

"Clinical trial data on effective preventive interventions for dementia are currently lacking," says Dr. Tolppanen.

"Although [the researchers] state that DSDRS could be used to select candidates for trials, it should be noted that diabetes and many of the components of the score are often exclusion criteria for medication trials."

New Risk Score Predicts 10-Year Dementia Risk for Type 2 Diabetes Patients
not yet ratednot yet rated

Researchers at Kaiser Permanente and the University Medical Centre Utrecht in the Netherlands have created the first risk score that predicts the 10-year individualized dementia risk for patients with type 2 diabetes, as reported in the inaugural issue of Lancet Diabetes & Endocrinology.

The researchers developed and validated the Diabetes-Specific Dementia Risk Score by examining data from nearly 30,000 patients with type 2 diabetes aged 60 and older over a 10-year period. They found eight factors that were most predictive of dementia - including microvascular disease, diabetic foot and cerebrovascular disease - and assigned each a value related to their association with dementia to create an overall score for patients. The researchers found that individuals in the lowest category of the 20-point risk score had a 5.3 percent chance of developing dementia over the next 10 years, while those in the highest category had a 73 percent chance. Compared with those in the lowest category, those in the highest were 37 times more likely to get dementia, according to the study.

"Patients with type 2 diabetes are twice as likely to develop dementia as those without the disease, but predicting who has the highest future risk is difficult," said Rachel Whitmer, PhD, an epidemiologist at the Kaiser Permanente Division of Research in Oakland, California, who led the study. "While a few dementia risk scores exist, this is the first one that has been developed specifically for individuals with type 2 diabetes and encompasses diabetes-specific characteristics."

All predictors included in the Diabetes-Specific Dementia Risk Score are easy to obtain and based primarily on medical history, so the risk score can be calculated during a routine medical visit or with electronic health records. No labor-intensive or expensive tests, such as cognitive function or brain imaging, are required.

"This risk score is crucial for the care of patients with diabetes since they are particularly susceptible to dementia. It provides clinicians with an easy and efficient tool to assess their patients' chances of developing dementia over the next 10 years," Whitmer said. "Early detection of diabetes patients who are at increased future risk of dementia could help to develop and target preventive treatment."

According to the Centers for Disease Control and Prevention, more than 25 million children and adults in the United States have diabetes with type 2 diabetes in particular accounting for more than 90 percent of these cases. In addition to being a risk factor for dementia, diabetes is the leading cause of kidney failure, non-traumatic lower-limb amputations and new cases of blindness among adults in the United States.

"The risk score could be useful in the selection of high-risk patients for early intervention studies and for many applications of personalized medicine," said Geert Jan Biessels, MD, professor of neurology at the University Medical Centre Utrecht and co-author of the study. "Clinicians can use it to guide their decisions in terms of clinical attention to incipient cognitive impairment which makes people vulnerable to dangerous side-effects of diabetes treatment. The risk score will also help us to understand the causes of diabetes associated increased dementia risk, because we can examine those at high risk in early stages of the dementia process."

Insulin pumps 'better than injections' for type 1 diabetes

Insulin pumps 'better than injections' for type 1 diabetes
not yet ratednot yet rated

Researchers say that insulin pumps are more effective at controlling type 1 diabetes in children and cause fewer complications than insulin injections, having completed the longest and largest study of insulin pumps to date.

According to the researchers at the Princess Margaret Hospital for Children in Australia, the use of pump therapy has increased over the last 15 years, particularly in children.

Pump therapy involves having a catheter placed under the skin to deliver short-acting doses of insulin around the clock. The insulin pump delivers the dosage at two levels: at the basal rate, the normal level of blood insulin needed when a person with diabetes has not eaten or is asleep; and the bolus rate, the level of insulin needed when a diabetic eats.

The study, published in the journal of the European Association for the Study of Diabetes, analyzed 345 children with type 1 diabetes undergoing pump therapy, and the same number of children who treat their diabetes with injections.

All children were aged between 2 and 19-years-old and had a mean diabetes duration of 4.1 years at the start of pump therapy. The follow-up mean duration period for the children was 3.5 years.

Results of the analysis revealed that the use of insulin pumps reduced episodes of severe hypoglycemia - dangerously low blood glucose - from 14.7 events in every 100 patients a year, to 7.2 episodes.

Numbers of severe hypoglycemic events in children using insulin injections, meanwhile, went up over the same period, from 6.8 events in every 100 patients per year, to 10.2 episodes.

Additionally, the rate of admission for diabetic ketoacidosis was lower in children using pump therapy at 2.3 events per every 100 patients per year, compared with 4.7 events per every 100 patients per year using insulin injections.

Dr. Elizabeth Davis, an associate professor at the Princess Margaret Hospital for Children, says the results of this study are strong due to its large population-based sample over a long period of time.

"This is the largest study of insulin pump use in children. It also has the longest follow-up period of any study of insulin pump therapy in children," she says.

Dr. Davis adds:

"Our data confirm that insulin pump therapy provides an improvement in glycemic control which is sustained for at least seven years.

Although this is not a randomized trial, it is 'real life' experience in a large population-based sample over a prolonged time period and, as such, provides important information."

In other research on insulin pumps, presented at the American Diabetes Association 73rd Scientific Sessions in Chicago this year, one model of insulin pump was found to reduce nocturnal hypoglycemia without affecting glycated hemoglobin levels.

The authors of this latest research note that of the children using pump therapy, 38 stopped the treatment during the course of the study.

They explain that some children may have stopped because they became tired of the extra attention taken to manage the pump. Children may also be concerned about its physical appearance.

Protection against type 2 diabetes offered by a Mediterranean diet and diets low in available carbohydrates
not yet rated5 stars

New research shows that a Mediterranean-style diet and diets low in available carbohydrates can offer protection against type 2 diabetes. The study is published in Diabetologia, the journal of the European Association for the Study of Diabetes (EASD), and is by Dr Carlo La Vecchia, Mario Negri Institute of Pharmacological Research, Milan, Italy, and colleagues.

The authors studied patients from Greece who are part of the ongoing European Prospective Investigation into Cancer and nutrition (EPIC), led by Dr. Antonia Trichopoulou, from the University of Athens. From a total of 22,295 participants, actively followed up for just over 11 years, 2,330 cases of type 2 diabetes were recorded. To assess dietary habits, all participants completed a questionnaire, and the researchers constructed a 10-point Mediterranean diet score (MDS) and a similar scale to measure the available carbohydrate (or glycaemic load [GL]) of the diet.

People with an MDS of over 6 were 12% less likely to develop diabetes than those with the lowest MDS of 3 or under. Patients with the highest available carbohydrate in their diet were 21% more likely to develop diabetes than those with the lowest. A high MDS combined with low available carbohydrate reduced the chances of developing diabetes by 20% as compared with a diet low in MDS and high in GL.

The authors say: "The role of the Mediterranean diet in weight control is still controversial, and in most studies from Mediterranean countries the adherence to the Mediterranean diet was unrelated to overweight. This suggests that the protection of the Mediterranean diet against diabetes is not through weight control, but through several dietary characteristics of the Mediterranean diet. However, this issue is difficult to address in cohort studies because of the lack of information on weight changes during follow-up that are rarely recorded."

They point out that a particular feature of the Mediterranean diet is the use of extra virgin olive oil which leads to a high ratio of monounsaturated to saturated fatty acids. But again research here has been conflicting. One review of dietary fat and diabetes suggests that replacing saturated and trans fats with unsaturated fats has beneficial effects on insulin sensitivity and is likely to reduce the risk of type 2 diabetes. However, in a randomised trial of high-cardiovascular-risk individuals who were assigned to the Mediterranean diet supplemented with either free extra virgin olive oil or nuts and were compared with individuals on a low-fat diet (comparison group), there was no difference in diabetes occurrence between the two variants of the Mediterranean diet when compared with the comparison group.

Regarding GL, the authors say: "High GL diet leads to rapid rises in blood glucose and insulin levels. The chronically increased insulin demand may eventually result in pancreatic ß cell failure and, as a consequence, impaired glucose tolerance and increased insulin resistance, which is a predictor of diabetes. A high dietary GL has also been unfavourably related to glycaemic control in individuals with diabetes."

They conclude: "A low GL diet that also adequately adheres to the principles of the traditional Mediterranean diet may reduce the incidence of type 2 diabetes."

Subset of type 1 diabetes patients with strong response to therapy identified
not yet ratednot yet rated

Primary results from a new clinical trial show that patients with type 1 diabetes treated with the monoclonal antibody teplizumab (MacroGenics, Inc.) exhibit greater preservation of C-peptide, a biomarker of islet cell function, compared to controls. Further analyses identified a discrete subset of the treatment group that demonstrated especially robust responses ("responders"), suggesting that these patients could be identified prior to treatment. The trial, entitled "Autoimmunity-Blocking Antibody for Tolerance in Recently Diagnosed Type 1 Diabetes" (AbATE), was conducted by the Immune Tolerance Network (ITN). The results are available online and will be published in the November issue of the journal Diabetes.

The AbATE study, led by Kevan Herold, MD (Yale University), tested teplizumab, which targets the CD3 receptor found on T cells, in patients with new-onset type 1 diabetes. CD3 is required for T-cell activation, which can lead to the destruction of insulin-producing beta cells. A previous ITN study with teplizumab showed that a single course of the drug slowed C-peptide decline in new-onset patients for a year, after which the effects waned. The aim of the AbATE study was to test whether C-peptide preservation could be prolonged by administering two courses of teplizumab, one year apart.

In this open-label, Phase II study, 77 new-onset patients (ages 8 to 30 years old) were randomized to receive either teplizumab or a control. Those in the treatment arm received the scheduled treatment consisting of two 14-day courses of teplizumab, one year apart. Both arms received intensive diabetes care from certified diabetes educators and were followed for two years. The primary endpoint compared C-peptide preservation between the two groups.

After two years, the teplizumab-treated group showed significantly greater preservation of C-peptide (75-percent higher responses compared to the control group).

Further analysis revealed that within the treatment arm two groups of patients could be distinguished based on their C-peptide levels: one group, considered "responders" (22/49), showed very little C-peptide decline over the course of the study (only a 6 percent reduction from baseline), while the "non-responders" (27/49) exhibited a similar rate of C-peptide decline as the control group (less than 40-percent reduction from baseline).

Investigators measured various biomarkers and cell types that might distinguish between these two groups. They found that, at trial entry, "responders" had lower hemoglobin A1c levels (a marker of glucose concentration in the blood) and used less insulin at baseline, compared to "non-responders". Differences in specific T-cell subsets also distinguished between the two groups at baseline, suggesting that immune status might contribute to drug responsiveness. However, further studies will be required to confirm these results.

"This overall approach to identifying characteristics of individuals most likely to respond to therapies shows great promise because the responders in this study experienced a robust and prolonged drug effect," said Dr. Herold. "This type of response has not been seen in other studies of immune therapies."

Type 1 diabetes is a disease marked by immune destruction of insulin-producing beta cells in the pancreas. New-onset patients usually have 20 to 40 percent of their normal beta cell mass remaining, which is still capable of producing insulin. Preserving this remaining mass, even temporarily, could improve long-term clinical outcomes.

Immune modulators, like teplizumab, represent a promising means of inducing tolerance; however, no drug has been shown to prevent or reverse disease, and only a few have temporarily delayed disease progression. The ability to identify a subgroup of patients who may be more responsive to therapy could greatly enhance the clinical use of immune modulators and improve outcomes for those patients. Further analyses with specimens collected from the AbATE study are ongoing to understand the mechanism of response.

Depression in patients with type 2 diabetes was associated with greater cognitive decline in a study of almost 3,000 individuals who participated in a clinical trial, according to a report published by JAMA Psychiatry, a JAMA Network publication.

Depression and diabetes are among the most common illnesses in older primary care populations. Up to 20 percent of adult patients with type 2 diabetes meet the criteria for major depression. Both depression and diabetes appear to be associated with an increased risk for dementia, Mark D. Sullivan, M.D., Ph.D., of the University of Washington, Seattle, and colleagues write in the study background.

"Depression has been identified as a risk factor for dementia among patients with type 2 diabetes mellitus but the cognitive domains and patient groups most affected have not been identified," the study notes.

The study included 2,977 patients with type 2 diabetes at high risk for cardiovascular disease who were participants in the Action to Control Cardiovascular Risk in Diabetes-Memory in Diabetes (ACCORD-MIND) trial. Researchers used tests to gauge cognition and a questionnaire to assess depression.

According to the results, patients with scores indicative of depression showed greater cognitive decline during the 40-month follow-up on all tests. The effect of depression on risk of cognitive decline did not differ according to previous cardiovascular disease; baseline cognition or age; or intensive vs. standard glucose-lowering treatment, blood pressure treatment, lipid treatment or insulin treatment, the results also indicate.

"In summary, this epidemiological analysis of the effect of depression on risk for cognitive decline among participants in the ACCORD-MIND study showed that depression is associated with cognitive decline in all domains assessed and that this effect does not differ in important clinical subgroups. This suggests that a potentially reversible factor may be promoting general cognitive decline in the broad population of patients with type 2 diabetes. Since dementia is one of the fastest growing and most dreaded complications of diabetes, our findings may be important for public health," the study concludes.

Diabetes hospitalization: some antibiotics 'raise risk'
not yet ratednot yet rated

Researchers have found that, compared with other antibiotics, people with diabetes taking a class known as fluoroquinolones may be at higher risk of blood sugar-related complications.

Researchers from National Taiwan University in Taipei, carried out a population-based cohort study of around 78,000 people with diabetes.

The researchers analyzed data from the claims database for Taiwan's national insurance program, and looked at patients who had received an oral prescription of one of these three different classes of antibiotics: fluoroquinolones (levofloxacin, ciprofloxacin or moxifloxacin), second-generation cephalosporins (cefuroxime, cefaclor or cefprozil), acrolides (clarithromycin or azithromycin).

The scientists analyzed the number of emergency visits and hospitalizations related to diabetes within 30 days of the patients using the antibiotics. The visits were for dysglycemia, with blood sugars either too high (hyperglycemia) or too low (hypoglycemia).

The study, published in the journal Clinical Infectious Diseases, revealed that the patients with diabetes using fluoroquinolones had a higher risk of dysglycemia than the diabetics using other antibiotics.

The research showed that the risk was dependent on the type of antibiotic the patient was using within the class of fluoroquinolones.

The incidence, or absolute risk, of hyperglycemia cases for every 1,000 people was:

Moxifloxacin - 6.9Ciprofloxacin - 4.0Levofloxacin - 3.9.

The absolute risk of hypoglycemia cases per every 1,000 people was:

Moxifloxacin - 10.0Levofloxacin - 9.3Ciprofloxacin - 7.9.

Fluoroquinolones are a class of antibiotics with a wide number of uses against bacterial infection.

By comparison, the researchers found the absolute risks were lower among diabetes patients taking other antibiotics that can be used. The numbers were: In the macrolides class: 1.6 per 1,000 (hyperglycemia), 3.7 (hypo)For cephalosporin antibiotics: 2.1 per 1,000 (hyperglycemia), 3.2 (hypo).

The researchers say that previous research has linked fluoroquinolones to dysglycemia. They note that one of the fluoroquinolone antibiotics, gatifloxacin, was withdrawn from the US market in 2006 due, the researchers say, "to the risk of blood sugar abnormalities."

The study authors conclude that this research should prompt clinicians to consider the risks when prescribing fluoroquinolones for diabetes patients. They authors say:

"Our results showed a class effect regarding increased risk of severe dysglycemia among diabetic patients administered ?uoroquinolones in Taiwan."

"Clinicians should consider these risks when treating patients with diabetes and prescribe ?uoroquinolones cautiously."

People with diabetes can spot hypoglycemia early. Low blood sugar can, however, become serious, as listed by the Mayo Clinic: clumsiness or jerky movements, muscle weakness, difficulty speaking or slurred speech, blurry or double vision, drowsiness, confusion, convulsions or seizures, and unconsciousness.

High blood sugars, hyperglycemia, can "become severe and lead to serious complications requiring emergency care, such as diabetic coma."

Scientists discover new type of protein modification, may play role in cancer and diabetes

Scientists discover new type of protein modification, may play role in cancer and diabetes
not yet ratednot yet rated

Scientists at The Scripps Research Institute (TSRI) have discovered a new type of chemical modification that affects numerous proteins within mammalian cells. The modification appears to work as a regulator of important cellular processes including the metabolism of glucose. Further study of this modification could provide insights into the causes of diabetes, cancer and other disorders.

"It appears to be an intrinsic feedback mechanism in glucose metabolism, but I suspect that its other functions throughout the cell will prove at least as interesting when they are more fully elucidated," said Benjamin F. Cravatt, chair of the Department of Chemical Physiology and member of the Skaggs Institute for Chemical Physiology at TSRI.

Cravatt and his postdoctoral fellow Raymond E. Moellering reported the finding in the August 2, 2013 issue of the journal Science.

The Cravatt laboratory has long studied the natural chemical modifications that can change the functions of proteins "on the fly," switching their biological activities on or off or otherwise altering them. The better known of these modifications include phosphorylation, the addition of a small molecule known as a phosphate group, and acetylation, the addition of an acetyl group.

In search of new protein modifiers, Cravatt and Moellering, whose postdoctoral fellowship is sponsored in part by the Howard Hughes Medical Institute and the Damon Runyon Cancer Research Foundation, decided to investigate a small molecule known as 1,3-bisphosphoglycerate (1,3-BPG). The molecule's chemical makeup suggested that it might readily react with some proteins to form semipermanent, function-altering modifications. 1,3-BPG is one of the main "intermediate" molecules produced during glycolysis, which is a core metabolic pathway that converts glucose to cellular fuel.

"1,3-BPG's intrinsic reactivity seemed odd to us, considering that it is such a central metabolite," remembered Moellering.

Moellering's initial test-tube experiments showed that 1,3-BPG does indeed react with certain lysine amino acids to modify GAPDH, the enzyme that mediates the production of 1,3-BPG. "That gave us the first indication that this reaction does happen, and that we should therefore start looking for it in cells," he said.

After devising new methods to detect this unique lysine modification in human cell cultures, Moellering soon found it - on other glucose-metabolizing enzymes, as well as on proteins seemingly unrelated to glucose metabolism.

"With every step we took, the project became more interesting, because we were finding signs that this reaction occurs frequently in cells and in animal tissues, and in unexpected cellular locations, too," Moellering said.

He detected the signature of the new lysine modification not only on proteins in the main volume of the cell (the cytosol), but also in the DNA-containing cell nucleus and even on the cell's membrane compartments.

"It appears that wherever GAPDH goes within cells, it is capable of catalyzing the localized production of 1,3-BPG, which in turn reacts with nearby proteins to modify their structure and function," said Cravatt.

Moellering found that when 1,3-BPG's lysine modification occurs on glucose-metabolizing enzymes, it tends to inhibit their activities, causing a slowdown of central glucose processing and a consequent buildup of certain glucose metabolites in the processing pathway. Moellering and Cravatt suspect that these overabundant metabolites may end up being shunted into other cellular processes besides basic fuel-making - processes that contribute to the synthesis of new molecules and even cell proliferation.

Moellering also discovered that 1,3-BPG and the modification it makes on proteins become more prevalent as glucose levels rise. Within the context of glucose metabolism, 1,3-BPG's modification thus seems to act as a "very old, maybe ancient feedback mechanism for regulating that central metabolic pathway," Moellering said.

The abnormal processing of glucose within cells features in a number of major diseases including cancer and diabetes. "Cancer cells, for example, bring in as much as 20 times more glucose than non-cancerous cells of the same type," Moellering noted. He now wants to find out whether 1,3-BPG is part of the problem in such cells. At abnormally high levels, it conceivably could help force glucose metabolism toward the runaway cell proliferation that is a hallmark of cancer.

Cravatt and Moellering also want to learn more about what 1,3-BPG's lysine modification does in the nuclei and membrane compartments of cells, where they found evidence of it. "We suspect that it works to connect glucose metabolism to other pathways, perhaps as a kind of signaling mechanism," said Moellering.

Already Moellering has uncovered evidence that there are enzymes that work to reverse 1,3-BPG's modification of lysines - which underscores the likelihood that this modification represents a fundamental, dynamic mechanism in cells. "We'd like to discover which enzymes catalyze the removal of the modification," said Cravatt, "because then, in principle, we could use inhibitors of these enzymes to control the levels of the modification and get a better understanding of its biological functions as well as the conditions under which it occurs."

Funding for the study, "Functional Lysine Modification by an Intrinsically Reactive Primary Glycolytic Metabolite," was provided by the National Institutes of Health (CA087660), the Skaggs Institute for Chemical Biology at TSRI and the Damon Runyon Cancer Research Foundation.

Gastric bypass offers clues to solving diabetes

Gastric bypass offers clues to solving diabetes
4 and a half stars4 stars

Scientists have discovered why a gastric bypass can help cure type 2 diabetes, according to a study published in the journal Science.

Researchers from Boston Children's Hospital reveal that the small intestine, which they had thought to be a passive organ, is actually a major contributor to the body's metabolism.

The researchers say that previous research has already shown that gastric bypass surgery can help resolve type 2 diabetes. However, they add that until now, the reason for this has been unclear.

The research team studied the after-effects of gastric bypass surgery in rats over a year and analyzed the way the small intestine processed glucose.

The researchers found that the small intestine uses and disposes of glucose. This regulates blood glucose levels which then helps to resolve type 2 diabetes.

Nicholas Stylopoulos of the division of endocrinology at the hospital, says:

"We have seen type 2 diabetes resolve in humans after gastric bypass, but have never known why. People have been focusing on hormones, fat and muscle, but we have shown in this study that the answer lies somewhere in the small intestine most of the time."

Gastric bypass surgery is a weight-loss treatment usually reserved for severely obese individuals. It works by redirecting the food into a smaller pouch in the stomach, bypassing the stomach and duodenum - the first section of the small intestine.

The researchers discovered that following gastric bypass surgery, the small intestine "reprograms" itself to produce GLUT-1, which is not usually present before surgery.

GLUT-1 usually works as a "transporter," responsible for removing glucose from the circulation and using it within the intestine.

However, the scientists discovered that after surgery, GLUT-1 takes glucose from the circulation and disposes of it, leading to stabilized glucose levels in the rest of the body.

The researchers say that of the rats analyzed after gastric bypass surgery, 100% had been cured of type 2 diabetes. They add that 64% of the diabetes had been cured by the gut surgery alone, while the other 36% could be a result of weight loss or other factors.

Nicholas Stylopoulos says this research could lead to investigating ways of "mimicking" the intestine's programming without the need for surgery: "Previously, we had not considered the intestine as a major glucose-utilizing organ. We have found this process is exactly what happens after surgery." Stylopoulos added:

With further research, we may find ways to bypass the bypass.

The results of our study are promising because, unlike the brain and other organs, intestines are easily accessible.

Furthermore, since cells in the intestine have such a short lifespan, we can easily study and pharmacologically manipulate them to use glucose, without long-term problems."

Previous research has suggested that although gastric bypass surgery helps diabetic symptoms disappear for some patients, it is not a long-term cure.

Scientists from the Group Health Research Institute carried out a study revealing that in 4,434 patients who had gastric bypass surgery, their symptoms of type 2 diabetes returned within five years of the operation.

A new FDA approved diet pill called Belviq just went on the market. Belviq make people more likely to succeed with weight loss since they feel full more quickly and it reduces food cravings. People who take Belviq with diet and exercise were 2 times more likely to lose 5% body weight and 3 times more likely to lose 10% body weight than the people who just did diet and exercise alone. The label states that if you do not lose 5% of your body weight in 12 weeks then consider stopping. Those that do respond in 12 (about 45% of patients) weeks go on to lose over 10% of their body weight in one year. Losing 22 pounds for a 220 pound person is life changing. So 45% of those taking Belviq lose significant amount of weight.
Belviq has a second mode of action to reduce blood sugar which may end up preventing diabetes in many cases. Diabetics and pre-diabetics who took Belviq, REGARDLESS of weight loss, saw their blood sugar numbers drop by double digit percentages. IE HbA1c -0.9 to -1.2 and fasting glucose feel -27. The cost of medications to reduce HbA1c levels exceeds the cost of Belviq. (see Arena's BloomDM phase III trial http://clinicaltrials.gov/ct2/show/NCT00603291 ) These reductions in diabetic symptoms plus the weight loss at the same time makes Belviq a medical bargain: http://www.belviq.com/ .

Glucose intolerance, diabetes or insulin resistance not associated with pathological features of alzheimer disease

Glucose intolerance or insulin resistance do not appear to be associated with pathological features of Alzheimer disease (AD) or detection of the accumulation of the brain protein ß-amyloid (''ß), according to a report published by JAMA Neurology, a JAMA Network publication.

Glucose intolerance and diabetes mellitus have been proposed as risk factors for the development of AD, but evidence of this has not been consistent, the study background notes.

Madhav Thambisetty, M.D., Ph.D., of the National Institute on Aging, Baltimore, and colleagues investigated the association between glucose intolerance and insulin resistance and brain ''ß burden with autopsies and imaging with carbon 11-labeled Pittsburgh Compound B positron emission tomography.

"The relationship among diabetes mellitus, insulin and AD is an important area of investigation. However, whether cognitive impairment seen in those with diabetes is mediated by excess pathological features of AD or other related abnormalities, such as vascular disease, remains unclear," the authors comment.

Two groups of participants were involved in the study. One group consisted of 197 participants enrolled in the Baltimore Longitudinal Study of Aging who had two or more oral glucose tolerance tests (OGTT) while they were alive and then underwent a brain autopsy when they died. The second group included 53 living study participants who had two or more OGTTs and underwent imaging.

"In this prospective cohort with multiple assessments of glucose intolerance and insulin resistance, measures of glucose and insulin homeostasis are not associated with AD pathology and likely play little role in AD pathogenesis," the study concludes. "Long-term therapeutic trials are important to elucidate this issue."

How Botox works could reveal diabetes secrets

How Botox works could reveal diabetes secrets
not yet rated5 stars

Understanding the proteins that are targeted by the cosmetic drug Botox (onabotulinumtoxinA) could lead to breakthroughs against type 2 diabetes, according to researchers at Heriot-Watt University in Scotland.

The researchers are using new microscopic techniques on Soluble NSF Attachment Protein Receptor (SNARE) proteins with an aim of discovering how insulin is regulated and how this can change in the development of type 2 diabetes.

Botox targets SNARE proteins, preventing them from helping the muscles contract. But the proteins also exist in the beta-cells of the pancreas.

The research team plan to observe the SNARE proteins within the beta-cells of the pancreas, which help the beta-cells release the insulin by attempting to stabilize blood glucose levels.

The researchers say type 2 diabetes can develop in people who have long-term obesity, when the beta-cells are unable to cope with long-term high glucose levels and secrete less insulin. They add that this process means the beta-cells lose both mass and function, but the reasons for this are unknown. This is what the researchers will attempt to find out.

Dr. Colin Rickman of the Heriot-Watt University told Medical News Today:

"The idea is that we want to look at these proteins and look at how they are arranged on the membrane, what they are doing, how they are interacting, and how they change the diabetic's history."

"Nobody has ever done this before," Dr. Colin Rickman added. He told MNT:

"The interesting angle is that we are going to use microscopy, which allows us to see the individual molecules in the cell.

Normally you just see a cell, but you can't see the individual proteins in the cell.

These techniques allow us to see tens of thousands of these molecules in the cell and look at how they are interacting and what they are up to."

Depending on the final results of the research, he says that the work could lead to new methods of diagnosing diabetes, and even lead to ways of preventing it through early risk identification.

Dr. Colin Rickman said:

"Type 2 diabetes is usually caused by overconsumption of food and lack of exercise. People can live with obesity absolutely fine, until they reach that tipping point. But nobody really knows why the cells go through this tipping point.

"This research could enable us to understand how these processes are arranged and how it changes them to diabetic conditions.

"We could then use that as an assay to find out whether people are in danger of developing type 2 diabetes."

The team has already started preliminary investigations, analyzing the proteins and how they are arranged, but the biggest part of the study is yet to come in terms of analyzing different proteins and cells types and discovering the general principles of how they change.

Dr. Colin Rickman adds that further results will be ready by the end of this year and the full study should reach completion by the early part of 2015.

"The idea is that we want to look at these proteins and look at how they are arranged on the membrane, what they are doing, how they are interacting, and how they change the diabetic's history."

"Nobody has ever done this before," Dr. Colin Rickman added. He told MNT:

"The interesting angle is that we are going to use microscopy, which allows us to see the individual molecules in the cell.

Normally you just see a cell, but you can't see the individual proteins in the cell.

These techniques allow us to see tens of thousands of these molecules in the cell and look at how they are interacting and what they are up to."

Depending on the final results of the research, he says that the work could lead to new methods of diagnosing diabetes, and even lead to ways of preventing it through early risk identification.

"Type 2 diabetes is usually caused by overconsumption of food and lack of exercise. People can live with obesity absolutely fine, until they reach that tipping point. But nobody really knows why the cells go through this tipping point.

"This research could enable us to understand how these processes are arranged and how it changes them to diabetic conditions.

"We could then use that as an assay to find out whether people are in danger of developing type 2 diabetes."

The team has already started preliminary investigations, analyzing the proteins and how they are arranged, but the biggest part of the study is yet to come in terms of analyzing different proteins and cells types and discovering the general principles of how they change.

Dr. Colin Rickman adds that further results will be ready by the end of this year and the full study should reach completion by the early part of 2015.

A new FDA approved diet pill called Belviq just went on the market. Belviq make people more likely to succeed with weight loss since they feel full more quickly and it reduces food cravings. People who take Belviq with diet and exercise were 2 times more likely to lose 5% body weight and 3 times more likely to lose 10% body weight than the people who just did diet and exercise alone. The label states that if you do not lose 5% of your body weight in 12 weeks then consider stopping. Those that do respond in 12 (about 45% of patients) weeks go on to lose over 10% of their body weight in one year. Losing 22 pounds for a 220 pound person is life changing. So 45% of those taking Belviq lose significant amount of weight.
Belviq has a second mode of action to reduce blood sugar which may end up preventing diabetes in many cases. Diabetics and pre-diabetics who took Belviq, REGARDLESS of weight loss, saw their blood sugar numbers drop by double digit percentages. IE HbA1c -0.9 to -1.2 and fasting glucose feel -27. The cost of medications to reduce HbA1c levels exceeds the cost of Belviq. (seeArena's BloomDM phase III trial) These reductions in diabetic symptoms plus the weight loss at the same time makes Belviq a medical bargain.

Health Tips & Info : Understanding Gestational Diabetes Mellitus.

For the majority of women, carrying a child is the greatest blessing one can ever experience. It is a joyous time for both expectant parents because it is a celebration of another life. Even though a lot of women go through discomforts while pregnant, these are quickly managed since most of these minor pains ease off typically right after the first trimester. Unluckily for a couple of women, pregnancy is considered a problematic time because of complications that need a whole lot of attention and consideration. And one particular common complication of pregnancy is gestational diabetes mellitus or GDM, also known as gestational diabetes in pregnancy.Gestational diabetes mellitus is defined as glucose intolerance that affects pregnant women. It occurs in around 4 percent to 10 percent of women that are pregnant and often goes away after delivery. Women who are likely to suffer from GDM are the following: pregnant women who are obese, women who are 25 years and older, women who have history of GDM with previous pregnancies, history of giving birth to a big baby (usually 9 lbs. or more) and family history of type 2 diabetes.The symptoms of gestational diabetes mellitus are usually ignored because they are confused with the normal discomforts of pregnancy. The most prevalent symptoms of gestational diabetes are: increased frequency of urination, increased thirst and increased hunger. However, there are tests available in order to know whether these symptoms are brought about by hormonal imbalances that normally occur during pregnancy or if these are already signs of gestational diabetes mellitus.Oral glucose tolerance test (OGTT) measures the response of insulin to glucose loading. This type of procedure is typically done during the 24th to 28th week of pregnancy. This gestational diabetes test necessitates the pregnant woman to fast at least eight hours before heading to the lab. Later on, she will be requested to consume a sweetened liquid with 50- to 200-g of sugar. A small amount of blood sample will then be extracted at .25, 1, 2 and 3 hours intervals. Gestational diabetes mellitus is confirmed if the 2-hr value is 200 mg/dL or greater.Being healthy is always a priority when one is pregnant. It’s worthwhile to have regular checkups so that your doctor can keep track of your condition and try everything that’s possible to help you and your little one become satisfied and healthy.

Health Tips & Info : Unveiling The Causes Of Gestational Diabetes.

Gestational diabetes or GDM is a type of diabetes that affects only pregnant women, typically during the second trimester of pregnancy. About 4 to 10 percent suffer from this condition, making it one of the most common concerns of expectant mothers. Gestational diabetes can indeed be hard to understand but to simply put it, it means that a person has unusually high levels of sugar in the blood, thus the term “high blood sugar”.One of two conditions occurs in gestational diabetes. Possibly, there isn’t sufficient insulin in the blood or the body is not responding to insulin as necessary (also called “insulin resistance”). Insulin is a hormone that is vital in regulating carbohydrate (glucose) and fat metabolism in the body. It pushes the body to take up glucose (sugar) from the blood in order that the liver can store it as glycogen. Small amounts of insulin or insulin resistance both lead to the same thing – sugar is not taken up and thus accumulates in the blood.It is also believed that certain pregnancy hormones place pregnant women at risk for developing such condition. Human Placental Lactogen, cortisol, estriol, and progesterone are pregnancy hormones that are thought to hinder insulin from doing its job. If the body becomes resistant to insulin, blood sugar levels rise. To compensate for such increase in the amount of glucose in the blood, the pancreas tries to produce more insulin. The pancreas has its limits though. If the pancreas cannot keep up with the increased demand for insulin, the sugar levels rise and gestational diabetes occurs.Some other risk factors that can make women susceptible to GDM are: being overweight, family history of diabetes, previously giving birth to a big baby (usually 9 lbs or more in weight), having gestational diabetes with previous pregnancies and having too much amniotic fluid (termed as “polyhydramnios”).Most people may find it hard to understand the causes of gestational diabetes. But keep in mind that as a mother, you can always do something to counteract the causes of gestational diabetes. Proper diet, exercise and regular prenatal check-ups are just some of the things you can do to make sure that you and your baby will have a healthy, stress-free, and fun-filled journey together.
