Delayed Gastric Emptying Is Associated With Early and Long-term Hyperglycemia in Type 1 Diabetes Mellitus.

ABSTRACT: After the Diabetes Control and Complications Trial (DCCT), the Epidemiology of Diabetes Interventions and Complications (EDIC) study continued to show persistent benefit of prior intensive therapy on neuropathy, retinopathy, and nephropathy in type 1 diabetes mellitus (DM). The relationship between control of glycemia and gastric emptying (GE) is unclear.We assessed GE with a (13)C-spirulina breath test and symptoms in 78 participants with type 1 diabetes at year 20 of EDIC. The relationship between delayed GE and glycated hemoglobin (HbA1c), complications of DM, and gastrointestinal symptoms were evaluated.GE was normal (37 participants; 50%), delayed (35 participants; 47%), or rapid (2 participants; 3%). The latest mean HbA1c was 7.7%. In univariate analyses, delayed GE was associated with greater DCCT baseline HbA1c and duration of DM before DCCT (P ? .04), greater mean HbA1c over an average of 27 years of follow-up evaluation (during DCCT-EDIC, P = .01), lower R-R variability during deep breathing (P = .03) and severe nephropathy (P = .05), and a greater composite upper gastrointestinal symptom score (P < .05). In multivariate models, retinopathy was the only complication of DM associated with delayed GE. Separately, DCCT baseline HbA1c (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.3) and duration of DM (OR, 1.2; 95% CI, 1.01-1.3) before DCCT entry and mean HbA1c during DCCT-EDIC (OR, 2.2; 95% CI, 1.04-4.5) were associated independently with delayed GE.In the DCCT/EDIC study, delayed GE was remarkably common and associated with gastrointestinal symptoms and with measures of early and long-term hyperglycemia. ClinicalTrials.gov numbers NCT00360815 and NCT00360893.

Project description:Background & aimsRM-131, a synthetic ghrelin agonist, greatly accelerates gastric emptying of solids in patients with type 2 diabetes and delayed gastric emptying (DGE). We investigated the safety and effects of a single dose of RM-131 on gastric emptying and upper gastrointestinal (GI) symptoms in patients with type 1 diabetes and previously documented DGE.MethodsIn a double-blind cross-over study, 10 patients with type 1 diabetes (age, 45.7 ± 4.4 y; body mass index, 24.1 ± 1.1 kg/m(2)) and previously documented DGE were assigned in random order to receive a single dose of RM-131 (100 μg, subcutaneously) or placebo. Thirty minutes later, they ate a radiolabeled solid-liquid meal containing EggBeaters (ConAgra Foods, Omaha, NE), and then underwent 4 hours of gastric emptying and 6 hours of colonic filling analyses by scintigraphy. Upper GI symptoms were assessed using a daily diary, gastroparesis cardinal symptom index (total GCSI-DD) and a combination of nausea, vomiting, fullness, and pain (NVFP) scores (each rated on a 0-5 scale).ResultsAt screening, participants' mean level of hemoglobin A1c was 9.1% ± 0.5%; their total GCSI-DD score was 1.66 ± 0.38 (median, 1.71), and their total NVFP score was 1.73 ± 0.39 (median, 1.9). The t1/2 of solid gastric emptying was 84.9 ± 31.6 minutes when subjects were given RM-131 and 118.7 ± 26.7 when they were given a placebo. The median difference (Δ)was 33.9 minutes (interquartile range [IQR] -12, -49), or -54.7% (IQR, -21%,-110%). RM-131 decreased gastric retention of solids at 1 hour (P = .005) and 2 hours (P = .019). Numeric differences in t1/2 for gastric emptying of liquids, solid gastric emptying lag time, and colonic filling at 6 hours were not significant. Total GCSI-DD scores were 0.79 on placebo (IQR, 0.75, 2.08) and 0.17 on RM-131 (IQR, 0.00, 0.67; P = .026); NVFP scores were lower on RM-131 (P = .041). There were no significant adverse effects.ConclusionsRM-131 significantly accelerates gastric emptying of solids and reduces upper GI symptoms in patients with type 1 diabetes and documented DGE.

Project description:BackgroundIt remains controversial as to whether delayed gastric emptying in functional dyspepsia is associated with a specific symptom pattern, and it is unknown if gastric emptying in functional dyspepsia is a driver of impaired health related quality of life (HRQOL). We aimed to evaluate the relationship between functional dyspepsia symptoms, gastric emptying, and HRQOL.MethodsUS patients (n=864; mean age 44 years (range 18-82); 74% female) with functional dyspepsia, as defined by Rome II criteria, were enrolled into one of four clinical trials. All patients had a baseline scintigraphic assessment of gastric emptying of an egg substitute meal, and the trials were stratified on this assessment. Delayed gastric emptying was defined as having at least 6.3% residual volume at four hours. A total of 290 (34%) patients had delayed gastric emptying. HRQOL was assessed by the SF 36 and Nepean dyspepsia index (NDI).ResultsPostprandial fullness was independently associated with delayed gastric emptying but the association was weak (odds ratio (OR) 1.98 (95% confidence interval (CI) 1.02, 3.86); p=0.04). No independent association was seen with epigastric pain, early satiety, nausea, or bloating. Mean SF 36 physical composite score (PCS) was 42.3 (95% CI 41.6, 43.0) and the mean SF 36 mental composite score (MCS) was 46.8 (95% CI 46.0, 47.5); both mean scores were significantly lower than age and sex adjusted national norms of 50 (p<.0001). Female sex, increasing age, and higher symptom scores for fullness, epigastric pain, and nausea were each independently associated with decreased PCS scores (all p<0.05). Higher baseline nausea symptom score, lower gastric emptying rates at one hour, and lower body mass index were associated with decreased MCS (all p<0.05). Female sex, epigastric pain, and nausea, but not gastric emptying, were associated with an impaired score on the NDI. However, the magnitude of the significant associations were all small.ConclusionsIn patients with functional dyspepsia selected for a clinical trial programme, gastric emptying did not usefully stratify them symptomatically. Quality of life of patients with functional dyspepsia enrolled in this clinical trial programme was significantly impaired but this was not explained by delayed gastric emptying.
