      Omega 3 fatty acids are safe and may be effective for maintenance of remission in CD when used in enteric coated capsules. However, there are not sufficient data to recommend the routine use of n-3 for maintenance of remission in CD. The small number of patients in the included studies warrants further larger RCTs.[Abstract]

Omega-3 fatty acids inhibit an increase of proinflammatory cytokines in patients with active Crohn’s disease compared with omega-6 fatty acids
      The proinflammatory and anti-inflammatory cytokines were measured in plasma from 31 patients with active Crohn’s disease. Patients were randomized for oral intake of omega-3 fatty acid (3-Impact Powder) or omega-6 fatty acids (6-Impact Powder). The 3-Impact Powder showed immunomodulatory properties and might inhibit an increase of proinflammatory cytokines in contrast to the 6-Impact Powder.[Article]

      Nineteen patients with IBD-related joint pain were included in the study; 9 had Crohn disease and 10 had ulcerative colitis. The results suggest distinctive, differential prolonged effects on IBD-related joint pain of short-term duodenal administration of n-3-rich seal oil (significant improvement) and n-6-rich soy oil (tendency to exacerbation).[Abstract]

      Dietary supplementation with fish oil plus antioxidants is associated with modified PBMC composition and lower production of PGE(2) and IFN-gamma by circulating monocytes or macrophages. The response of extraintestinal manifestations of CD should be investigated in a randomized controlled trial.[Article]

Nutritional supplementation with N-3 fatty acids and antioxidants in patients with Crohn’s disease in remission: effects on antioxidant status and fatty acid profil
      In addition, supplementation with n-3 fatty acids plus antioxidants significantly changed the eicosanoid precursor profile, which may lead to the production of eicosanoids with attenuated proinflammatory activity. This study indicates that an immunomodulating formula containing n-3 fatty acids and/or AO may have the potential to play a role in the treatment of CD.[Abstract]

      Crohns disease is an inflammatory bowel disease that can have a significant impact on the health of those afflicted. The results from clinical trials have been conflicting, but a new fish oil preparation that limits the side effects of traditional fish oil therapy shows promise as an adjunctive treatment for Crohns disease.[Abstract]

    Boswelia serrata

    1. Ammon HP. Planta Med. 2006 Oct;72(12):1100-16. Boswellic acids in chronic inflammatory diseases
      Clinical studies, so far with pilot character, suggest efficacy in some autoimmune diseases including rheumatoid arthritis, Crohn’s disease, ulcerative colitis and bronchial asthma. Side effects are not severe when compared to modern drugs used for the treatment of these diseases.[Abstract]
    2. Ammon HP. Wien Med Wochenschr. 2002;152(15-16):373-8. Boswellic acids (components of frankincense) as the active principle in treatment of chronic inflammatory diseases
      A series of chronic inflammatory diseases are thought to be perpetuated by leukotrienes. In clinical trials promising results were observed in patients with rheumatoid arthritis, chronic colitis, ulcerative colitis, Crohn’s disease, bronchial asthma und peritumoral brains edemas.[Abstract]
    3. Ammon HP. Phytomedicine. 2010 Sep;17(11):862-7. Modulation of the immune system by Boswellia serrata extracts and boswellic acids
      From the pharmacological properties of BEs and BAs it is not surprising that positive effects of BEs in some chronic inflammatory diseases including rheumatoid arthritis, bronchial asthma, osteoarthritis, ulcerative colitis and Crohn’s disease have been reported.[Abstract]

      The study confirms that therapy with H15 is not inferior to mesalazine. This can be interpreted as evidence for the efficacy of H15 according to the state of art in the treatment of active Crohn’s disease with Boswellia serrata extract, since the efficacy of mesalazine for this indication has been approved by the health authorities. Considering both safety and efficacy of Boswellia serrata extract H15 it appears to be superior over mesalazine in terms of a benefit-risk-evaluation.[Abstract]

    Probiotica

      Notably, Crohn’s disease, an inflammatory bowel disease of yet unknown aetiology, is associated with intestinal dysbiosis with a lower representation of the Clostridium leptum group among the Firmicutes phylum.[Abstract]
    2. Mitsuyama K, Toyonaga A, Sata M. J Gastroenterol. 2002 Nov;37 Suppl 14:73-7. Intestinal microflora as a therapeutic target in inflammatory bowel disease
      Although recent data support a potential therapeutic role for probiotics and prebiotics in patients with IBD, such treatments need to be further assessed by large, double-blind controlled trials. A better understanding of the intestinal microflora and the mechanisms of their action may help us to develop more effective treatment for IBD.[Abstract]

      Application of the physiologic bacteria reduced the risk for relapse and minimized the need for glucocorticoids. Therefore we are convinced that in Crohn’s disease parts of the intestinal microflora, including the host’s immune response toward indigenous flora or an impairment of the gut flora’s metabolic activity are involved in the development or at least in the onset of relapse from remissive of colonic Crohn’s disease. However, more data are necessary to prove the benefit of E. coli strain Nissle 1917 as a new therapy to maintain remission of colonic Crohn’s disease.[Abstract]

      On the clinical side, CDAI scores fell from 275+/-15 to below 175+/-12 in wormwood group with remission of symptoms in eight patients (CDAI score below 170 or reduction by 70 points), compared to only two in the placebo group (CDAI of placebo group 282+/-11 at baseline and 230+/-14 on week 6). IBDQ also reflected accelerated clinical response with wormwood. Of clinical significance were the findings that wormwood also improved mood of the CD patients, as reflected in Hamilton’s Depression Scale. These findings provide a base to test wormwood in clinical conditions thought to be mediated by increased production of pro-inflammatory cytokines such as TNF-alpha.[Abstract]
    2. Omer B, Krebs S, Omer H, Noor TO. Phytomedicine. 2007 Feb;14(2-3):87-95. Epub 2007 Jan 19. Steroid-sparing effect of wormwood (Artemisia absinthium) in Crohn’s disease: a double-blind placebo-controlled study
      These results strongly suggest that wormwood has a steroid sparing effect. The improvements in HAMD scores indicate that wormwood also has an effect on the mood and quality of life of CD patients, which is not achieved by other standard medications.[Abstract]

    5. RIVM 2011
      “Uit de peiling blijkt ook dat een deel van de bevolking minder vitamine A, B1, C en E, magnesium, kalium en zink binnen krijgt dan wordt aanbevolen. Onderzoek is nodig naar de effecten hiervan op de gezondheid”.Artikel.

    5-ASA agents

    1. Akobeng AK, Gardener E. Cochrane Database Syst Rev. 2005 Jan 25;(1):CD003715. Oral 5-aminosalicylic acid for maintenance of medically-induced remission in Crohn’s Diseas
      We found no evidence in this review to suggest that 5-ASA preparations are superior to placebo for the maintenance of medically-induced remission in patients with Crohn’s disease. Therefore it appears that additional randomised trials of this regime are not justified. [Abstract]
