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

Endpoint Classification: Safety/Efficacy Study

Primary Outcome Measures:
  • Change in fatigue severity scale [ Time Frame: From baseline to 3 months after intervention initiation ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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.


Ages Eligible for Study:   18 Years to 70 Years

Inclusion Criteria:

  • Patients will have had previously macro- and microscopically verified Crohn's disease, as defined by traditional clinical and endoscopic standards.

  • In addition, patients will need to answer "yes" to the screening study entry question ("Is fatigue a signficant problem for you currently?").

Exclusion Criteria:

  • Exclusion criteria will include:

    • age <18 or >70 years
