NCT05057819
Bariatric surgery is an effective anti-obesity treatment providing durable weight loss and profound beneficial effects on glucose metabolism. However, bariatric surgery also comes with an increased risk for a late metabolic complication known as postbariatric hypoglycaemia (PBH). The condition presents with hypoglycaemic episodes 1-3 hours after meals and develops one to several years after bariatric surgery, mainly gastric bypass. PBH affects approximately 30% of patients without preexisting diabetes. For a subset of patients, hypoglycaemia-associated impairment of daily living and social functioning are commonly observed. The underlying mechanisms of PBH are multifactorial. It is considered that inadequately high insulin secretion caused by both accelerated glucose absorption from the gut and increased insulinotropic hormones such as GLP-1 are important pathophysiologic mechanisms. Empagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor reduces glucose exposure by increasing urinary glucose excretion. In a pilot study, a single dose of 10mg of empagliflozin taken before a mixed meal reduced the risk of PBH by 74%. Both, postprandial glucose and insulin exposure were significantly lower with empagliflozin vs. placebo, which makes Empagliflozin a potential treatment for PBH. In this study, treatment naïve patients will be randomized to receive either oral empagliflozin 25 mg daily in the morning for 20 days, followed by 2-6 weeks wash out and 20 days placebo once daily in the morning, or the reverse sequence. Urine and blood analysis will be performed as detailed in the protocol.
NCT01923649
The purpose of this study is to assess if Somatuline autogel 90 mg is effective in the treatment of dumping syndrome.
NCT02971631
Patients who have undergone gastrectomy (removal of the stomach) to treat or prevent cancer are known to have a significantly reduced quality of life. To date, there is very little information on the physiological causes of this. The investigators suspect that overproduction of a hormone (chemical) called glucagon like peptide-1 (GLP-1) released by the lining of the gut may play a role in the reduced appetite, weight loss and low blood sugar symptoms seen in this group. To investigate this, the investigators will study the response of 16 patients who have previously had a gastrectomy to a glucose drink, and a meal, while receiving an infusion of a specific blocker of GLP-1 or placebo. The investigators will examine the levels of sugar and associated hormones in the blood, food consumption and food reward behaviour using standard tools. Participants will be invited to attend the Clinical Research Facility at Addenbrooke's Hospital for a screening visit, and two whole day study visits. The study has been designed to assess the role of overproduction of GLP-1 by completely blocking its actions, rather than assess the use of the blocking compound as a medication, and is therefore regarded as a physiological study, not a clinical trial. The goal of this study is to demonstrate the magnitude of effect of GLP-1 on blood sugar and appetite derangement in patients who have had a gastrectomy. This will guide future work on the development of novel treatment paradigms for the post-gastrectomy patient group.
NCT02525705
The purpose of this study is to evaluate the prevalence at 3.5 months of age of dumping syndrome in children operated at birth for oesophageal atresia type III et IV.
NCT03200782
The purpose of the study is to investigate whether hypoglycaemia observed after food intake in bariatric patients can be either influenced by an SGLT2 inhibitor, empagliflozin, or via inhibition of inflammation with an human interleukin-1 receptor antagonist (IL1-RA, anakinra).
NCT01637272
multi-center, phase II study evaluating efficacy, safety and pharmacokinetics of pasireotide in patients with dumping syndrome
NCT01895296
Dumping Syndrome consists of (1) a too rapid gastric emptying, (2) an inappropriate release of GI hormones (as a reaction to the hyperosmolar contents in the duodenum) and (3) an hyperinsulinemic response to a too rapid absorption of glucose. Because it is not well known which somatostatin receptor(s) (sst1-5) influence(s) Dumping Syndrome most, the goal of this trial is to evaluate : * the effect of pasireotide (sst1, 2, 3, 5 agonist) on the control of gastric emptying. * the effect of pasireotide (sst1, 2, 3, 5 agonist) on the release of GI hormones (during OGTT). * the effect of pasireotide (sst1, 2, 3, 5 agonist) on the hyperinsulimic response (during OGTT). * the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of objective parameters of Dumping Syndrome (hematocrit (Hct), pulse rate and occurrence of hypoglycemia after an Oral Glucose Tolerance Test (OGTT) with 75g of glucose) * the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of overall symptoms as measured by the combined Dumping Syndrome score * the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of symptoms as measured by (a) early and (b) late phase dumping symptom score separately * the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of quality of life (QoL SF-36)
