Primary purpose: TREATMENT

Brief summary: The Aim of this randoized controlled pilot study is to find a better treatment strategy for active UC based on the recent knowledge regarding the microbiota in UC and the beneficial or detrimental effects of antibiotics in restoring gut health and reducing inflammation. This study is designed to determine whether therapy with two antibiotics during a flare - amoxicillin and doxycillin, will be better than the current published antibiotic treatment combination using these antibiotics with metronidazole ( as the latter which may degrade beneficial species without adding benefit towards reducing pathobionts)

Detailed description: Recent studies suggest that UC is associated with alterations of the microbiota. Further support for targeting the microbiota includes several studies demonstrating that antibiotics might be helpful for severe refractory colitis. Antibiotics may work by reducing pathobionts, by causing niche expansion of beneficial bacteria , and may harm if they do not reduce pathobionts or reduce beneficial commensals Recently, a triple antibiotic therapy with amoxicillin, metronidazole and tetracycline was developed for UC. However, a recent study on the effect of 11 different oral antibiotics on gut bacteria found that seven of them including metronidazole might cause lbacterial translocation . Anaerobes are critical for butyrate production. .

Based on these recent studies, it would appear that tetracycline and amoxicillin are more likely to cause the beneficial effect, while metronidazole might actually be detrimental. Thus by removing metronidazole the investigators might actually have a better effect both for efficacy and safety.
