简要总结

Diabesity (Diabetes accompanied by obesity) is a prevalent condition many times complicated by micro- and macrovascular disease. Many treatments for Diabesity paradoxically cause further weight gain and hypoglycemia. The Endobarrier enables diabetes control along with weight loss as an alternative to bariatric surgery for patients who are not interested or not qualified for surgery. The aim of this study is to assess the efficacy and safety of the Endobarrier Diabesity patients in Israel.

This study will include 45 men and women between the ages of 18-65 with HbA1c level of 8% and above and a BMI of 30 kg/m2 or above.

Exclusion criteria: use of anti-coagulant, use of steroids or inability to discontinue these medications.

The cohort will be followed for two years during which the patients will be monitored for diabetes control (by using a continuous glucose monitor), weight, blood pressure, lipid profile, fatty liver (by Ultrasound and blood markers for inflammation and fibrosis) and change in plasma gut peptide levels. The Endobarrier will be explanted after one year, however the monitoring of the patients will continue for another year.

详细描述

Current therapies including diet, exercise, behavior modifications, oral diabetes agents, and insulin, are employed to control Type 2 Diabetes mellitus (T2DM), but rarely return subjects to euglycemia, require dose escalation over time and can be associated with hypoglycemia and weight gain. Obesity is a well-established risk for both the development of diabetes as well as for increased mortality. The majority of individuals with T2DM are overweight or obese. Obesity and type 2 diabetes mellitus are common and well documented risk factors for non-alcoholic fatty liver disease (NAFLD). For some patients NAFLD disease is a relatively benign condition, for others NAFLD will progress to cirrhosis and end-stage liver disease with associated complications including hepatocellular carcino.The current treatment for NAFLD and nonalcoholic steatohepatitis (NASH) is weight reduction which can be achieved by life style modifications, drug therapy or bariatric surgery. The Fibro Test and Fibro Max have proven their efficacy as noninvasive biomarkers for NAFLD and NASH in large scale studies. Transient Elastography which measures liver stiffness non-invasively has been successful in identifying fibrosis in NAFLD.

In addition, designated sonography is a sensitive noninvasive method for steatosis quantification which can diagnose small amounts of liver fat that would be missed by conventional sonography and is not affected by fibrosis or steatohepatitis.

Bariatric Surgery for T2DM In light of this, bariatric surgery has recently emerged as one of the most effective means of providing durable, clinically-significant resolution of diabetes. The majority of subjects with T2DM who undergo these procedures have remission of this disorder. In a large bariatric surgery meta-analysis published in Journal of the American Medical Association in 2004, within studies reporting resolution of diabetes, 76.8% of subjects experienced complete resolution; within studies reporting both resolution and improvement or only improvement of diabetes, 85.4% of subjects experienced resolution or improvement of diabetes. All bariatric operations result in remarkable improvement in T2DM although with varying degrees of efficacy. Resolution of diabetes often occurs within days following bariatric surgery, even before marked weight loss is achieved. Resolution of diabetes is more prevalent following the more "malabsorptive" procedures (BPD or duodenal switch) and the mixed malabsorptive/restrictive Roux-en-y (RYGB) in contrast to the purely restrictive vertical banded gastroplasty (VBG) and laparoscopic adjustable gastric banding (LAGB) procedures. In addition, there appears to be a gradation of diabetes resolution as a function of the operative procedure: 98.9% for BPD, 83.7% for RYGB, 71.6% for VBG, and 47.9% for LAGB. Subjects with the shortest duration and mildest form of T2DM had a higher rate of T2DM resolution after surgery, suggesting that early surgical intervention is warranted to increase the likelihood of rendering subjects euglycemic. Recently, it has been published that subjects with long-standing uncontrolled diabetes and non-morbid obesity have a high remission rate (88%) of their diabetes following RYGB surgery. However, despite the considerable effectiveness shown by bariatric surgery in resolving diabetes, surgery has not yet become a standard of care for subjects who are obese with diabetes. In part because of an incomplete understanding of the mechanisms of action, this concept of gastrointestinal surgery as an endocrine modifier is not yet fully embraced by the clinical community and has yet to be incorporated into care strategies.12 But perhaps more importantly, some clinicians evoke the irreversibility of gastric bypass and the occasional reports of poor outcomes to label this approach "extreme" - to be reserved as a treatment of last resort.

Bariatric Surgery for NAFLD Weight loss following bariatric surgery results in a marked improvement in hepatic steatosis. An analysis of numerous paired biopsy studies reveals convincing evidence that significant improvement in steatosis and inflammation occurs in NAFLD patients after weight loss surgery. Regression and histologic improvement of NASH has been documented after bariatric surgery.

The "EndoBarrier" Gastrointestinal Liner System is an endoscopically-delivered device that offers an alternative to gastric bypass surgery. The device shields the duodenum and upper jejunum from contact with chyme, thereby mimicking the foregut bypass effect of a RYGB procedure without altering the subject's anatomy. Pancreatic and biliary secretions pass along the outside of the device and then mix with chyme in the upper jejunum. Based on animal experiments and clinical observations, the EndoBarrier device may provide a useful non-surgical intervention for treating T2DM, with an added benefit of weight loss. To date, over 13 studies enrolling over 500 subjects were performed with the EndoBarrier device. In one study, at 12 months 23/32 uncontrolled T2DM subjects (71.9%), were able to achieve an HbA1c value less than or equal to 7.0%.
