  Purpose

This is a randomized, double-blind, placebo-controlled study, comparing the effect of L-carnitine vs placebo on fatigue among Crohn's disease patients.

The specific aim of this study is to determine if treatment with L-carnitine is more effective than placebo at decreasing fatigue severity scores, while accounting for disease activity and concomitant anemia, depression/anxiety and poor sleep quality.


Condition Intervention
Crohn's Disease Fatigue Drug: L-carnitine Other: Placebo

Primary Outcome Measures:
  • Change in fatigue severity scale [ Time Frame: From baseline to 3 months after intervention initiation ]
    The Fatigue Severity Score is a validated instrument to assess fatigue associated with chronic disease. The scale ranges from scores from 9 to 63, with a higher score indicated greater fatigue.


Secondary Outcome Measures:
  • Change in Multidimensional Fatigue Inventory [ Time Frame: From baseline to 3 months after intevention initiation ]
    This is a validated instrument to measure fatigue and has been validated for use for patients with inflammatory bowel disease. Scores range from 4-20, with higher scores indicated more severe fatigue.

  • Change in handgrip strength [ Time Frame: From baseline to 3 months after treatment intervention ]
    Handgrip strength will be assessed by a portable dynanometer. Maximal force after three tries will be recorded.


Enrollment: 0
Study Start Date: August 2013
Estimated Study Completion Date: February 2014
Estimated Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Carnitine
Patients will take 4grams of L-carnitine (2 grams twice daily) for 3 months
Drug: L-carnitine
dietary supplement
Placebo Comparator: Placebo
Patients will take placebo for 3 months. Placebo is manufactured by the same company as the L-carnitine and will have a similar appearance.
Other: Placebo
Patients will receive placebo, which will be manufactured by the same supplier as L-carnitine and appears identical. Patients will take an equal number of pills (8 pills/day).

Detailed Description:
A total of 100 patients will be recruited, in order to be able ensure to detect a significant difference in fatigue between the treatment and control groups.
