    Pathophysiology

     

    Crohn's disease, also known as Crohn syndrome and regional enteritis, is a type of inflammatory bowel disease (IBD) that may affect any part of the gastrointestinal tract from mouth to anus. Signs and symptoms includes abdominal pain, diarrhea (which may be bloody if inflammation is severe), fever, and weight loss. Other complications may occur outside the gastrointestinal tract and include anemia, skin rashes, arthritis, inflammation of the eye, and tiredness. The skin rashes may be due to infections as well as pyoderma gangrenosum or erythema nodosum. Bowel obstruction also commonly occurs and those with the disease are at greater risk of bowel cancer.

    Treatment

    Acute treatment uses medications to treat any infection (normally antibiotics) and to reduce inflammation (normally aminosalicylate anti-inflammatory drugs and corticosteroids). When symptoms are in remission, treatment enters maintenance, with a goal of avoiding the recurrence of symptoms. Prolonged use of corticosteroids has significant side-effects; as a result, they are, in general, not used for long-term treatment. Alternatives include aminosalicylates alone, though only a minority are able to maintain the treatment, and many require immunosuppressive drugs. It has been also suggested that antibiotics change the enteric flora, and their continuous use may pose the risk of overgrowth with pathogens such as Clostridium difficile.

    Major research on disease

    Recent studies using helminthic therapy or hookworms to treat Crohn's Disease and other (non-viral) auto-immune diseases seem to yield promising results. Numerous preclinical studies demonstrate that activation of the CB1 and CB2 cannabinoid receptors exert biological functions on the gastrointestinal tract. Activation of CB1 and CB2 receptors in animals has shown a strong anti-inflammatory effect. Cannabinoids and/or modulation of the endocannabinoid system is a novel therapeutic means for the treatment of numerous GI disorders, including inflammatory bowel diseases like Crohn's disease. A few small trials have looked at medical cannabis but further evidence is required to determine its usefulness.

    Statistics

    Altogether 2201 patients aged 15 years or more were identified, of whom 1379 were diagnosed as UC (including proctitis), 706 as CD, and 116 as indeterminate. The overall incidence per 100,000 at ages 15-64 years (standardised for age and sex) of UC was 10.4 (95% confidence interval (95% CI) 7.6 to 13.1) and that of CD was 5.6 (95% CI 2.8 to 8.3). Rates of UC in northern centres were 40% higher than those in the south (rate ratio (RR) = 1.4 (95% CI 1.2 to 1.5)) and for CD they were 80% higher (RR = 1.8 (95% CI 1.5 to 2.1)). For UC the highest reported incidence was in Iceland (24.5, 95% CI 17.4 to 31.5) and for CD, Maastricht (The Netherlands; 9.2, 95% CI 6.5 to 11.8) and Amiens (north west France; 9.2, 95% CI 6.3 to 12.2). The lowest incidence of UC was in Almada (southern Portugal) (1.6, 95% CI 0.0 to 3.2) and of CD in Ioannina (north west Greece) (0.9, 95% CI 0.0 to 2.2). An unexpected finding was a difference in the age specific incidence of UC in men and women with the incidence in women but not men declining with age
