Previous studies have shown a high prevalence of gastric parietal cell antibodies (PCA) in type 1 diabetes, which can be accompanied by (sub)clinical autoimmune gastric disease. This study aimed to determine the grade of associated autoimmunity and to assess the pattern of prevalence of PCA by gender, age, duration of disease, age at onset of diabetes, and human leukocyte antigen (HLA) type in an adult type 1 diabetic population. Furthermore, to examine the clinical significance of being PCA positive, manifestations of gastric autoimmune disease were studied in PCA-positive and PCA-negative patients.

OBJECTIVE To investigate whether autonomic neuropathy or hyperglycemia plays a crucial etiological role in gastric retention of ingesta frequently found in type I diabetic patients. RESEARCH DESIGN AND METHODS We investigated the gastric emptying of a radiolabeled semisolid 1,168 kJ meal in 38 female and 45 male patients (age 18–75 years; illness duration 3–46 years). None took drugs affecting gastrointestinal motility. Fasted patients underwent tests of cardiovascular autonomic and peripheral nerve function. Blood glucose levels were determined before and after the scintigraphic recording of gastric emptying. RESULTS The percentage of meal remaining in the stomach at the end of the 50-min recording time was related significantly to the patients' degree of cardiovascular autonomic neuropathy [r (81) = 0.235, P < 0.028] but not to their degree of peripheral neuropathy, preprandial blood glucose level, HbA1c indicative of glycemic control, diabetes duration, and age. The patien...

Individuals with diabetes are at increased risk for complications, including gastroparesis. Type 1 diabetes mellitus (T1DM) is an autoimmune disorder resulting in decreased beta-cell function. Glutamic acid decarboxylase-65 antibody (GADA) is the most commonly used test to assess autoimmunity while C-peptide level is used to assess beta-cell function. Patients with type 2 diabetes mellitus (T2DM), who are GADA positive, are labeled latent autoimmune diabetes in adults (LADA). To characterize patients with T1 and T2DM who have symptoms of gastroparesis using GADA and C-peptide levels and to look for association with the presence of gastroparesis and its symptom severity. 113 T1DM and 90 T2DM patients with symptoms suggestive of gastroparesis were studied. Symptom severity was assessed using Gastroparesis Cardinal Symptom Index (GCSI). Serum samples were analyzed for GADA and C-peptide. Delayed gastric emptying was present in 91 (81%) of T1DM and 60 (67%) of T2DM patients ( = 0.04). G...

A high prevalence of upper gastrointestinal symptoms is described in diabetic patients and, at least in part, this has been attributed to abnormal emptying of the stomach. In an unselected small series of dyspeptic patients with Type 2 diabetes mellitus (DM2), we previously described a higher prevalence of Helicobacter pylori (Hp) infection associated with autonomic neuropathy (AN) than in non-diabetic subjects. To evaluate the prevalence of Hp and its relationship with AN, we studied 164 DM2 patients, matched for sex, age (9 5 years) and body weight ( 9 kg) to 164 non-diabetic subjects, all affected with dyspepsia of unknown origin. Results document that the prevalence of peptic ulcer is similar in both groups of patients (20.1 vs 29.3%, P= n.s.); chronic gastritis was 50% in the control group and 35.4% in the DN2 group (PB0.01) and dyspepsia without ulcer and gastritis (simple dyspepsia) was significantly more frequent in DM2 patients than in non-diabetics (44.5 vs 20.7%, P B0.01). Hp infection was documented by histology of gastrointestinal mucosa in 74.4% of the DM2 patients and in 50% of the controls (P B 0.01) (ulcer: 97 vs 71%, P B0.05; gastritis: 72 vs 43.5%, PB 0.05; simple dyspepsia: 66 vs 35%, P B 0.01, respectively). Autonomic neuropathy was found in 65.2% of the DM2 patients (90.9% of patients with ulcer, 65.5% with gastritis and 53.4% with simple dyspepsia). A significant concordance (84.7%, P B 0.001) was found between the presence of AN and Hp infection. Data provide, for the first time, direct evidence for a higher frequency of Hp infection in dyspeptic patients affected with DM2 than in non-diabetic subjects. In addition, in diabetic patients the frequency of non-ulcer, non-gastritis dyspepsia is two times higher than in non-diabetics and is strictly associated with autonomic neuropathy, acting as a favoring factor for occurrence and recurrence of gastrointestinal disease.
Prevalence of Gastroparesis in Type 1 Diabetes Mellitus and its Relationship to Dyspeptic Symptoms
2010
Background and Aim: Gastroparesis and/or dyspeptic symptoms occur in around 50% of type 1 diabetic patients. The aim of our study was to evaluate the prevalence of gastroparesis in patients with type 1 diabetes using 13 Coctanoic acid breath test ( 13 C-OBT) and the relationship between dyspeptic symptoms and gastric emptying. Methods: Gastric emptying of solids was evaluated prospectively in euglycemic conditions in 69 type 1 diabetic patients (male/female: 36/33; mean age 49.5 ± 14.2 years; mean duration of diabetes 20.4 ± 8.2 years) and 40 healthy volunteers (male/female 17/23; mean age 34.3 ± 16 years) using 13 C-OBT. Dyspeptic symptoms, autonomic nerve function and Helicobacter pylori (H. pylori) status were assessed. Results: Solid gastric emptying was slower in diabetic patients (T1/2=125.36 ± 31.5min) than in healthy subjects (T1/2=88.5 ± 27.3 min) (p<0.05). Gastric emptying was slower in diabetic female compared to diabetic male patients (p<0.05). Body mass index (BMI) was the only independent predictor for delayed solid gastric emptying in a logistic regression model testing HbA1c, BMI, age, diabetes duration, H. pylori status, peripheral neuropathy, retinopathy, nephropathy, and autonomic neuropathy. Abdominal bloating and upper abdominal pain were associated with delayed gastric emptying. Conclusions: We found that 33.7% of type 1 diabetic patients had delayed gastric emptying that correlated with female gender, increased BMI, abdominal bloating and upper abdominal pain.
Autoimmune Gastritis in Type 1 Diabetes: A Clinically Oriented Review
The Journal of Clinical Endocrinology & Metabolism, 2008
Context: Autoimmune gastritis and pernicious anemia are common autoimmune disorders, being present in up to 2% of the general population. In patients with type 1 diabetes or autoimmune thyroid disease, the prevalence is 3-to 5-fold increased. This review addresses the epidemiology, pathogenesis, diagnosis, clinical consequences, and management of autoimmune gastritis in type 1 diabetic patients.
Delayed gastric emptying rate in Type 1 diabetics with cardiac autonomic neuropathy
Journal of Diabetes and its Complications, 2001
Gastroparesis is a frequent complication of longstanding diabetes and has been attributed to vagal nerve dysfunction, occurring as part of a generalized autonomic neuropathy. We wanted to clarify the relationship between delayed gastric emptying (GE) and cardiac autonomic neuropathy (CAN) in type 1 diabetics. Using a standardized ultrasound technique, GE was studied in 20 type 1 diabetic patients with poor glycaemic control despite good compliance and 10 normal healthy volunteers (Group 1). Measurements of GE were done on condition that the fasting blood glucose was 3.5 ± 9.0 mmol/l. Diabetic patients were classified into two groups according to the absence (Group 2) or presence (Group 3) of CAN, using the deep breathing test (E:I ratio) to evaluate parasympathetic vagal nerve function. Age-related reference values were used to evaluate the indices of CAN. The supine resting heart rate was also checked, and the patients were asked for symptoms of gastroparesis. The three groups were similar in terms of sex and smoking habits, and there was no significant difference regarding the age and body mass index (BMI). The mean duration of diabetes and the glycaemic control (HbA1c) was insignificant between patients in Groups 2 and 3. Diabetic patients in Group 3 showed lower gastric emptying rates (GER) than the healthy volunteers in Group 1 (median GER 16% vs. 63%, P < .01) and the patients in Group 2 (median GER 16% vs. 54%, P < .01). No significant difference in GER could be seen between patients in Group 2 and subjects in Group 1 (median GER 54% vs. 63%, P = .08). Assuming that GER < 45% indicated a delayed GE, 8 of 10 patients in Group 3 had delayed GE compared to only 3 of 10 patients in Group 2. There were disagreements between symptoms of gastroparesis and delayed GE. We conclude that there is a significant lower GER in type 1 diabetic patients with CAN than in those without, unrelated to symptoms of gastroparesis. D
