Arm Type
Experimental
Arm Label
Treatment
Arm Description
This an open-labeled study. All participants will be part of the treatment group and receive SAM-e. S-adenosyl methionine will be dosed as 200 mg tablets with doses ranging from 200 to 1400 mg daily.
Outcomes
Primary Outcome Measures
Wong-Baker FACES Pain Rating Scale
We scored the Wong-Baker Pain Rating Scale numerically on a scale of 0 (no pain) to 4 (worst pain).
Secondary Outcome Measures
Safety
Assessments of liver transaminases and alkaline phosphatasewere performed at baseline, 2 weeks, 1 month and 2 months. Depression and mania were assessed weekly.

5. Study Description
Brief Summary
This pilot study will investigate the efficacy of SAM-e for the treatment of recurrent abdominal pain in children. This will be an open-labeled study and all participants will receive SAM-e therapy. Given that SAM-e has been demonstrated to improve symptoms of depression and pain with minimal side effects as compared to other antidepressant therapy, we hypothesize that SAM-e will reduce pain symptoms among children with recurrent abdominal pain.
