Reviewer's report:
I read with interest the case report titled: "Severe spruelike enteropathy and
collagenous colitis caused by olmesartan"
This is a well-written and original case. I have some major comments:
- In the introduction, please add more references in lines 55-57 (page 4) and
better descibe their results. 
- In the discussion, please give more information regarding the previous findings
on the time from the treatment start and the appearance of diarrhea 
- In the discussion, more space should be given to the association between
spruelike enteropathy and collagenous colitis
