RESUMO
Background: Helicobacter pylori [H. pylori] is one of the most common bacterial infections worldwide. We designed a study to compare the efficacy of 14-day hybrid regimen with 10-day concomitant therapy for H. pylori eradication in Iran
Methods: 252 patients with naive H. pylori infection were randomly divided to receive either hybrid regimen [pantoprazole 40 mg, and amoxicillin 1 gr twice daily for 14 days, accompanied by clarithromycin 500 mg, and metronidazole 500 mg, twice daily just during the last 7 days] or concomitant regimen [pantoprazole 40 mg, amoxicillin 1 gr, clarithromycin 500 mg, and metronidazole 500 mg, all twice daily for 10 days]. 8 weeks after therapy, 14C- urease breath test was performed to confirm eradication
Results: According to intention to treat analysis, the eradication rates were 87.3% [95% CI: 81.4-93.1] and 80.9% [95% CI: 74-87.8] in hybrid and concomitant groups, respectively [p=0.38]. Per-protocol eradication rates were 89.3% [95% CI: 83.8-94.7] and 83.1% [95% CI: 76.3-89.8], respectively [p=0.19]. The rates of severe side effects were not statistically different between the two groups [4% vs. 8.7%]
Conclusion: 14-day hybrid therapy can be considered as a nearly acceptable regimen with few severe side effects in Iran. However, it seems that the efficacy of this therapy is decreasing as the resistance rates to antibiotics are increasing. We suggest further studies to assess the efficacy of a more prolonged concomitant therapy for H. pylori eradication in Iran
RESUMO
The adverse effects of non-steroidal anti-inflammatory drugs [NSAIDs] on the upper gastrointestinal [GI] tract and small intestine are well established. The effect of such therapy on the large intestine, so called NSAID-induced colopathy, is less well described. NSAID-induced colopathy usually involves the right colon due to a higher concentration of the drug at this site, but the rectum may also be involved. NSAIDs possibly damage the normal large intestine, which presents as ulceration, colitis and stricture. Even though several studies found that NSAIDs can cause diverticular bleeding and perforation, flare-up of inflammatory bowel disease, and play a role as an etiologic factor in lymphocytic colitis. Inflammatory bowel diseases, malignancy and infectious colitis must be ruled out before establishing the diagnosis of NSAID -induced colopathy. Discontinuation of the offending drug is mandatory. Here, we have reported the case of a 43-year-old female, NSAID user due to low back pain, who was admitted to the hospital with painless hematochezia
