  Purpose

Ulcerative colitis (UC) is a chronic inflammatory disease resulting in increased morbidity in patients. The current standard treatment for mild to moderate UC (MTMUC) includes 5-aminosalicylic compounds (5ASA) such as olsalazine and mesalamine, yet some patients continue to experience disease symptoms and flare-ups. These patients require higher dosages of 5ASA medications and in many cases escalate to steroid and/or immunosuppressant therapy which comprises higher risk of hazardous side effects.

Curcumin, an active ingredient of the Indian herb Rhizoma Curcuma Longa, has been extensively studied in the context of inflammatory diseases. In humans, a controlled study using curcumin as an adjusted therapy to 5ASA medication has shown it to be superior to placebo in maintaining remission in MTMUC patients . A small, preliminary open label study has also shown efficacy in reducing disease symptoms and inflammatory markers in this group of patients .

This data provides bases for investigating an integrative approach to optimize the current standard treatment in MTMUC patients. We speculate that using a combined therapy of 5ASA medication and curcumin could benefit this subgroup of patients and reduce morbidity and perhaps need for escalating pharmacological intervention.

Further study details as provided by Sheba Medical Center:

Primary Outcome Measures:
  • The percentage of patients who achieve clinical remission compared between the two study arms. [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    The percentage of patients who achieve clinical remission compared between the two study arms at week 4 after induction of therapy. Clinical remission is defined as score of ≤2 in the Simple Clinical Colitis Activity Index (SCCAI) .


Secondary Outcome Measures:
  • Time to response [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Time to response (TTR) compared between study and control groups. Response is defined as remission or significant improvement. TTR is defined by number of days to achieve clinical response.
