To determine the prevalence of complementary and alternative medicine (CAM) use over time in a population-based cohort of patients with inflammatory bowel disease (IBD).
The Manitoba IBD Cohort Study is a longitudinal, population-based study of multiple determinants of health outcomes in an IBD cohort. Participants completed semi-annual surveys, and annual in-person interviews. Enquiries about the use of 12 types of CAM service providers and 13 CAM products, based on items from a national survey, were included at months 0, 12, 30 and 54.
Overall, 74% of respondents used a CAM service or product in the 4.5-year period, with approximately 40% using some type of CAM at each time point, and 14% using CAM consistently at every time point. There was a trend for women to use CAM more than men; there was no difference in CAM use between patients with Crohn's disease and those with ulcerative colitis. The most often used CAM services (on average) were massage therapy (30%) and chiropractic (14%), physiotherapy (4%), acupuncture (3.5%) and naturopathy/homeopathy (3.5%). A wide range of CAM products were used, with Lactobacillus acidophilus (8%), fish and other oils (5.5%), glucosamine (4%) and chamomile (3.5%) as the most common. On average, only 18% of consumers used CAM for their IBD, so the majority chose it for other problems. There were no differences in psychological variables between CAM users and non-users.
Those with IBD commonly try CAM, although very few use these approaches regularly over the years. CAM is not usually used by patients with IBD for disease management, but clinicians should be aware that many will test the services and products.

    • "Therefore, the consequences can be potentially dangerous. The range of CAM therapies include: (i) hypnosis (Szigethy et al., 2011), (ii) acupuncture to decrease response to stress (Rawsthorne et al., 2012), (iii) megadoses of Vitamins and minerals, (iv) prebiotics (Oz and Ebersole, 2008; Oz et al., 2009) (v) probiotics (Mack, 2011), and (vi) Herbal Medicines (Geerling et al., 2000; Keefer et al., 2012). Amongst herbal therapy, tea and tea extracts have received a great deal of attention and are available over the counter (OTC). "

    ABSTRACT: Background: There is no cure for autoimmune chronic inflammatory bowel disease (IBD). IBD patients commonly use complementary and alternative medications of which the safety, efficacy, and interaction with standard-of-care therapies are not fully known. Thus the consequences can become life-threatening. Sulfasalazine commonly used in IBD, potentially has severe adverse effects, including infertility, pulmonary fibrosis, lack of response, and ultimately patients may require intestinal resection. We hypothesized that green tea polyphenols (GrTP, EGCG) and sulfasalazine have similar anti-inflammatory properties. Methods: BALB/c mice received Dextran sodium sulfate (DSS) to induce colitis (ulcerative colitis model). Exposure of IL-10 deficient mice (BALB/c-background) to normal microbiota provoked enterocolitis (mimics Crohn's disease). Animals were treated with agents incorporated into daily diets. Control animals received sham treatment. Results: DSS-treated animals developed severe bloody diarrhea and colitis (score 0-4, 3.2 ± 0.27). IL-10 deficient mice developed severe enterocolitis as manifested by diarrhea, rectal prolapse, and colonic lesions. Animals tolerated regimens (GrTP, EGCG, sulfasalazine) with no major side effects, and further developed less severe colitis. IL-10 deficient animals became moribund on high dose, while tolerated low and Mid doses with significant improved symptoms of enterocolitis. GrTP, EGCG, and sulfasalazine significantly ameliorated colonic damage and histological scores in treated animals in a similar manner (GrTP vs. DSS p < 0.05; EGCG, sulfasalazine vs. DSS p < 0.01). The inflammatory markers TNFα (3-fold), IL-6 (14-fold), and serum amyloid A (40-fold) increased in colitic animals and significantly decreased with treatment regiments. In contrast, circulatory leptin levels decreased in colitic animals (twofold). EGCG additionally reduced leptin levels (p < 0.01) while GrTP and sulfasalazine had no effect on leptin levels (p < 0.05). Hepatic and colonic antioxidants were significantly depleted in colitic animals and treatment regiments significantly restored antioxidants levels. Conclusion: GrTP and EGCG improved antioxidants levels and attenuated severity of colitis analogous to sulfasalazine. Future studies will reveal whether polyphenols can become an alternative/additive therapy for IBD therapy in humans.

    • "Overall, significantly more women than men reported CAM use. In the context of previous studies conducted on samples from the general population [36] and in the Scandinavian countries [12] [37] [38], along with other international studies investigating CAM use in IBD patients [9] [21] [22] [27] [28], our results were as anticipated . An association between female gender and CAM use has also been shown in studies involving other chronic diseases and cancer patients [39] [40] [41]. "

    ABSTRACT: The use of complementary and alternative medicine (CAM) has been increasing in recent decades. Our aim was to determine the proportion of CAM use among patients with inflammatory bowel disease (IBD) in a longitudinal, population-based cohort and to identify predictive factors for CAM use. The Inflammatory Bowel South-Eastern Norway (IBSEN) study is a population-based IBD cohort that has been followed prospectively for 10 years. The ten-year follow-up was conducted from 2000 to 2004 and included a questionnaire regarding CAM, a structured interview, a review of hospital records, a clinical examination, laboratory tests, and an ileocolonoscopy. Of the 620 patients evaluated at the ten-year follow-up, 517 (84%) completed the CAM questionnaire, 353 had ulcerative colitis (UC), 164 had Crohn's disease (CD), and 50% were male. Thirty percent reported the use of CAM at some point since their IBD diagnosis, and 7.5% reported current CAM use. More CD patients than UC patients reported CAM use (38% vs. 27%, respectively; p=0.01). Younger age, female gender, and higher education level predicted CAM use in UC, whereas younger age was the only predictor of CAM use in CD. Thirty-six percent of the CAM users were mostly satisfied or very satisfied with the treatment. One third of the patients in this population-based cohort had used CAM at some point during a ten-year disease course, but only 7.5% reported current CAM use. CAM use was more common in the CD than in the UC patients. Only socio-demographic factors, such as age, gender and education, predicted CAM use.

    ABSTRACT: Objectives: Inflammatory bowel diseases (IBD) have a huge impact on the patients' lives and require continuous medication and long-term medical follow-up. The Short Form Health Survey (SF-36) is a commonly used questionnaire measuring health-related quality of life (HRQOL). Our aim was to evaluate whether HRQOL influences medication adherence and vice versa in IBD patients, and to find relationships between demographic parameters, therapeutic modalities and non-adherence or HRQOL. Patients and methods: Five hundred ninety-two IBD patients treated at six Hungarian tertiary centers were enrolled. Patients completed the SF-36 questionnaire and a medication adherence report scale during their visits. The associations between demographic parameters, HRQOL, different kinds of therapies and non-adherence were analyzed. Results: The most affected dimension was physical functioning and least affected were the social functions. About 42.7% of the patients revealed their HRQOL to be acceptable. About 74.6% of the patients believed that the prescribed medications actually improved their HRQOL. Diarrhea was the most common and most severe symptom during the course of the disease. Non-adherence was reported in 13.4% of the patients. 'Forgetting to take the medication' was the main reason for non-adherence in 67.6% of the cases. Medication adherence was significantly higher among nonsmoker patients, and also in the case of immunomodulator therapy. There was no association between the sum of HRQOL and different subscores and non-adherence. Conclusion: Inflammatory bowel disease is associated with low HRQOL, which is not affected by drug therapy. The impaired quality of life in IBD is mainly influenced by the disease itself.
