Helicobacter pylori has been implicated in the cardiovascular risk of diabetic patients. The aim of our study was to investigate whether the Helicobacter pylori infection plays a role in the lipid and haemostasis patterns of type 1 diabetic patients. Twenty nine patients with type 1 diabetes mellitus and H. pylori infection were enrolled (Chlamydia pneumoniae negative). The H. pylori infection status was assessed by serology and urease breath test. In all patients levels of total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, lipoprotein (a) (Lpa) C reactive protein (CRP), fibrinogen, thrombin/antithrombin III complex (TAT), plasminogen activator inhibitor type 1(PAI-1), tissue plasminogen activator (t-PA) and von Willebrand antigen were measured. All patients were evaluated before and after H. pylori eradicating treatment with amoxicillin, clarithromycin and omeprazole. Twenty two patients were eradicated and seven remained infected. In H. pylori eradicated patients, HDL cholesterol increased (59.7+/-18.9 mg/dl vs 65.2+/-15. 9 mg/dl, P << 0.05), after treatment. After H. pylori eradication, the levels of CRP and TAT decreased (48+/-0.7 ng/l vs 3.3+/-0.4 ng/l;P << 0.05), (27.7+/-44.7 microg/ml vs 2.1+/-1.4 microg/ml, P << 0.05), respectively. The decrease in TAT was higher in the group of H. pylori (+) patients with higher levels of TAT (TAT >> 20 ng/ml, 92.8+/-41.6 ng/ml vs 1.9+/-2.0 ng/ml, P << 0.005; TAT 4Eth 20 ng/ml; 10.1+/-5.2 ng/ml vs 2.2+/-0.6 ng/ml, P << 0.05). These changes did not occur in patients without H. pylori eradication. Eradication of H. pylori infection in type 1 diabetic patients modifies some parameters of lipid and haemostasis patterns, (increase of HDL-cholesterol, reduction of Lpa and decrease of CRP and TAT) and so contributes to improvement of cardiovascular risk factors in these patients.

Helicobacter pylori (Hp) infection plays a role in gastric emptying (GE) in type 1 diabetic patients and may have implications for glycaemic control. The aim of our study was to investigate this relationship. Gastric emptying was studied in 13 patients with type 1 diabetes and Hp infection. The Hp infection status was assessed by serology and urease breath test (UBT). In addition upper gastrointestinal endoscopy with gastric mucosal biopsy was performed to look for gastritis. A radionuclide-labeled solid meal was used to study GE before and after eradication therapy (amoxicillin, clarithromycin and omeprazole) for Hp infection. All patients were evaluated for autonomic and peripheral neuropathy and were asked for symptoms of gastrointestinal motor dysfunction. Blood glucose levels were determined before the meal and at 30,60,90 and 120 min after the start of the meal. Home blood glucose self-monitoring and HbA(1c) were performed to document glycaemic control during the study. Three months after treatment, five patients were free of Hp infection and were without gastritis (group I: no Hp infection, no gastritis); eight of the patients continued to have gastritis after treatment (group II) and of these eight patients, six had gastritis without Hp infection and two had gastritis plus persistent Hp infection. These last two patients were re-treated with eradication therapy. Patients with gastritis were re-evaluated 6 months after initial treatment; at which time four were now free of gastritis and were added to group I (n=9) while four continual to have gastritis although without Hp infection (group II, n=4). In group I, GE half-time showed an increase (30.6+/-10.3 min vs. 60.2+/-15.4 min; P<0.05) while no change (28.8+/-9.5 vs. 26.9+/-8.7 min; n.s.) was observed in group II. GE half-time was not altered by autonomic and peripheral neuropathy or blood glucose during solid meal test. HbA(1c) did not change significantly after treatment in either groups but the blood glucose levels were more stable in group I compared to group II. A delay in GE was observed with disappearance of gastritis associated to H. pylori infection after eradication treatment in patients with type 1 diabetes. This change in GE could help to stabilise the blood glucose levels in these patients treated with insulin before each meal.
