Helicobacter pylori

Helicobacter pylori (HP) is a common worldwide infection with known gastrointestinal and nongastrointestinal complications. One of the gastrointestinal side effects posed for this organism is its role in diabetes and increased insulin resistance. The aim of this study was to evaluate the association between HP and insulin resistance in type 2 diabetic patients and nondiabetics. This cross-sectional study was carried out from May to December 2013 on 211 diabetic patients referred to diabetes clinic of Shahid Beheshti Hospital of Qom and 218 patients without diabetes. HP was evaluated using serology method and insulin resistance was calculated using HOMA-IR. The prevalence of H. pylori infection was 55.8% and 44.2% in diabetics and nondiabetics (P=0.001). The study population was divided into two HP positive and negative groups. Among nondiabetics, insulin resistance degree was 3.01±2.12 and 2.74±2.18 in HP+ and HP− patients, respectively P=0.704. Oppositely, insulin resistance was significantly higher in diabetic HP+ patients rather than seronegative ones (4.484±2.781 versus 3.160±2.327, P=0.013). In diabetic patients, in addition to higher prevalence of HP, it causes a higher degree of insulin resistance

Levofloxacin-containing triple therapy versus bismuth-based quadruple therapy as regimens for second line anti- Helicobacter pylori

Background: Although the prevalence of Helicobacter pylori infection decreased following the hygiene promotion and application of proper anti- H.pylori treatments, unfortunately gradual increase is reported in treatment failure; hence, application of a proper treatment regimen as a second-line therapy is of great importance. Methods: In the current randomized, clinical trial, a total of 120 patients with peptic ulcers who failed to respond to treatment were enrolled. In the OLA group, a regimen of omeprazole 40 mg/day, levofloxacin 1 g/day, and amoxicillin 2 g/ day was prescribed; however, a regimen of omeprazole 40 mg/day, bismuth sub-citrate 480 mg/day, furazolidone 400 mg/day, and amoxicillin 2 g/day was administered to the OFAB group. Both groups were treated for 2 weeks, and 6 weeks after the treatment, the urea breath test (UBT) was performed in the subjects. Collected data were analyzed with SPSS Version 18. At the end, 58 patients in group OLA and 57 patients in the OFAB group were analyzed. Results: According to the results of the current study, 96.7 of the subjects in the OLA and 95 in the OFAB groups completed the treatment course and the eradication rates were 86.7 and 78.3 in the OLA and OFAB groups, respectively (P=0.23). Treatment side effects were observed in 51.7 and 11.7 of the subjects in the OLA and OFAB groups, respectively (P<0.01). Conclusion: Both regimens were applicable as the second-line therapy due to insignificant difference between the results of the 2 groups; however, OLA regimen was superior to OFAB, due to lower side effects. &#160

Association of Helicobacter pylori Infection with Coronary Artery Disease: Is Helicobacter pylori a Risk Factor?

Background. Helicobacter pylori (HP) infection is the most common infection in the world and coronary artery disease (CAD) is probably associated with it. The aim of this prospective study was to evaluate the association between HP infection and CAD in suspected patients referred for coronary angiography. The coronary angiography was performed using Judkins method and patients were assigned to participate in CAD positive (>50% luminal diameter stenosis) and negative groups. The serum HP IgG antibody was checked. Results. Positive and negative CAD groups consisted of 62 and 58 patients, respectively. HP was more prevalent among CAD+ patients, and with increasing the number of coronary arteries with stenosis, the HP seropositivity increased so that 76.3% of patients with multiple vessel diseases (MVD) and 70% of patients with single vessel diseases (SVD) were HP seropositive versus 50% in control group (P=0.006). Positive CAD was significantly associated with HDL level (P=0.01) and ESR level (P=0.006). Also, CAD+ patients had higher CRP levels than controls and it was statistically different between SVD group and controls (P<0.05). Conclusion. HP infection is more prevalent in CAD positive patients and, in case of proving causal relationship, it can be considered as a reversible risk factor for CAD

Helicobacter pylori and Migraine: Is Eradication of Helicobacter pylori Effective in Relief of Migraine Headache?

Background: Association between Helicobacter pylori (HP) infection and migraine and the effect of HP eradication on relief of migraine headache have been studied but the results are controversial. Objectives: To evaluate the effect of HP eradication in treatment of patients affected by migraine. Materials and Methods: Eighty consecutive HP infected patients affected by migraine without aura were enrolled in this clinical trial. They have referred to an endoscopy clinic for work-up of HP infection from October 2013 to November 2014. Patients were randomly assigned in 2 groups using 2 different regimens; Group A: migraine treatment and a 14-day triple therapy for HP infection and Group B: migraine treatment without HP eradication. The mean duration (hour), headache severity (MIDAS) and the frequency (per month) of clinical headache attacks were calculated upon enrollment in the study and at 6 months and 12 months after treatment. All data were analyzed using SPSS version 16. Comparison of categorical variables across the groups was performed using Chi-square test. Results: In group A, HP infection was eradicated in 34 of 40 patients (85%). After treatment in eradicated patients compared with the control group there was significant decrease in severity and frequency (but not in duration) of the migraine attacks at 6 months (p<0.001) and significant decrease in intensity, frequency and duration of the migraine attacks at 12 months (p<0.001). Conclusion: HP should be considered and examined in migranous patients and eradication treatment can be beneficial for relief of clinical attacks
