Abstract
Background: Resistance to metronidazole is one of the most common reasons for Helicobacter pylori treatment failure with classic triple therapy. The clarithromycin–based regimen is not cost – effective for developing countries and also there is a lot of evidence about increase of clarithromycin resistance H-pylori. Furazolidone is a good substitute, but several side effects, limit its widespread use our previous revealed that most of side effects occurred in the beginning of second week of treatment, so decrease the period of furazolidone therapy to one week may be considered. The aim of the present study was to assess the efficacy and side effect of one week furazolidone in combination with bismuth subcitrate ,amoxycillin and omprazole
Methods: In this study, a total of 177 patients were enrolled and randomized to two groups and received the following medications: Group I: omprazole 220mg + amoxycillin 21gr + bismuth subcitrate 4120 mg for two weeks and furazolidone 2200mg for 1 week Group II: the same regimen as in group I except that one week furazolidone in group II patients followed by one week metronidazole 2500 mg/day (one week furazolidone and one week metronidazole).patients were followed after 2 weeks for side effect of drugs and compliance and control endoscopy was performed after 6 weeks and three biopsies spicimens from the antrum and three from the corpus were taken for a urease test and histology. Eradication was concluded if all the tests were negative for H-pylori
Results: One hundred fifty seven patients completed the study. Mean age was 38.84+10.42 and 55.4% were male and 44.6% were female. Two patients from group I and three patients from group II did not tolerate the regimen and were excluded from the study. No serious complication was detected in two groups. The eradication rate per protocol analysis and intention to treat analysis were 89% and 79.3% in group 1 and 86.6% and 74.4% in group 2.No significant statistical differents between two groups (P=0.32 , P=0.33).
Conclusion: One week furazolidone in combination with two weeks amoxicillin, omprazole and bismuth subcitrate is a good, safe and cost effective regimen for eradication of H-pylori. Addition of metronidazole in the second week of treatment period did not increase eradication rate.

Abstract
Background: As regard to high prevalence of Helicobacter pylori infection and complications of it's persistence, as well as anti-bacterial activity against of Helicobacter pylori and anti-inflammatory properties of omega-3 fatty acids, this study was conducted to evaluate the effects of supplementation with Docosahexaenoic Acid (DHA) on the eradication of Helicobacter pylori infection, some serum inflammatory markers and total antioxidant capacity.
Methods: In a double-blind, placebo-controlled clinical trial, 66 H. pylori positive patients (33 in the intervention group and 33 in the control group), along with tetra-drugs H. pylori eradication regimen, randomly received daily two grams morDHA supplement or Medium Chain Triglyceride (MCT) oil as placebo for 12 weeks. Dietary intake data was collected by 24 hour food recall and analyzed by Nutritionist IV software. Sampling from fasting blood and measuring weight, height, body mass index (BMI) and level of physical activity were done at the first and the end of the study. As well as, eradication test of the infection was performed for all patients at the end of the intervention.
Results: Eradication rate of the infection, the level of interleukin-6 (IL-6), high sensitivity C-reactive protein (hs-CRP) and total antioxidant capacity (TAC) didn't have significant difference between two groups at the end of the study (P>0.05), while the level of interleukin-8 (IL-8) was different between two groups (P=0.008). Difference of the concentration between the beginning and the end of the study was not significant in any factors between two groups (P>0.05).
Conclusion: Intake of morDHA supplement didn't have significant effect on the eradication of H. pylori, serum levels of IL-6, hs-CRP and TAC, while it was effective on the level of IL-8.
