[Impact of conflicts of interest on guideline recommendations : Empirical study within the second update of the German interdisciplinary S3 guidelines on fibromyalgia syndrome]. / Der Einfluss von Interessenkonflikten auf Leitlinienempfehlungen : Eine empirische Studie zur zweiten Aktualisierung der interdisziplinären S3­Leitlinie zum Fibromyalgiesyndrom.

BACKGROUND: The impact of conflicts of interest (COI) in general and of academic COI in particular on guideline recommendations in pain medicine has not yet been studied. Whether the inclusion of patients and of representatives of all relevant healthcare professions into a guidelines group is protective against a systematic bias of decisions of a guidelines group is currently unknown. METHODS: All members of the guidelines group declared their COI before the consensus conferences by a standard form according to the rules and standards of the Association of the German Medical and Scientific Societies. The acceptance or rejection and the strength of consensus of recommendations of the second update of the interdisciplinary guidelines on fibromyalgia syndrome was analyzed twice by first including and then excluding the votes of the guideline group members with COI related to a recommendation from the results of anonymous voting via an internet platform. RESULTS: A total of 42 persons from different healthcare professions and patients participated in the online voting on recommendations. Of the participants 29% had no COI according to the predefined criteria, 53% met the criteria of academic and 33% the criteria of financial COI. In the case of exclusion of participants with a COI related to a specific recommendation, 2 out of 23 recommendations (homeopathy, tramadol) were not accepted. In all votes, there were more participants without COI than with COI. CONCLUSION: Academic COI were more frequent than financial COI in the second update of the German interdisciplinary guidelines group on fibromyalgia syndrome. The impact of COI on guideline recommendations was low. The inclusion of patients and of all relevant healthcare professionals into a guidelines group is a protective factor against the influence of COI on guideline recommendations.

[Complementary and alternative therapies for fibromyalgia syndrome. Systematic review, meta-analysis and guideline]. / Komplementäre und alternative Verfahren beim Fibromyalgiesyndrom. Systematische Übersicht, Metaanalyse und Leitlinie.

BACKGROUND: The scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011. MATERIALS AND METHODS: The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The recommendations were based on level of evidence, efficacy (meta-analysis of the outcomes pain, sleep, fatigue and health-related quality of life), acceptability (total dropout rate), risks (adverse events) and applicability of treatment modalities in the German health care system. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies. RESULTS AND CONCLUSION: Meditative movement therapies (qi gong, tai chi, yoga) are strongly recommended. Acupuncture can be considered. Mindfulness-based stress reduction as monotherapy and dance therapy as monotherapy are not recommended. Homeopathy is not recommended. In a minority vote, homeopathy was rated as "can be considered". Nutritional supplements and reiki are not recommended.

[Alternative and complementary therapies in fibromyalgia syndrome]. / Komplementäre und alternative Verfahren beim Fibromyalgiesyndrom.

INTRODUCTION: Interdisciplinary S3 level guidelines were devised in cooperation with 8 medical, 2 psychological and 2 patient support groups. Results were elaborated in a multilevel group process. METHODS: On the bases of the "Cochrane Library" (1993-2006), "Medline" (1980-2006), "PsychInfo" (2006) and "Scopus" (2006) controlled studies and meta-analyses of controlled studies were analyzed. RESULTS: Only few controlled studies were found supporting in part the effectiveness of CAM therapies in the treatment of fibromyalgia syndrome. Due to the lack of information on long term efficacy and cost-effectiveness, only limited recommendations for CAM therapies can be given. CONCLUSION: Within a multicomponent therapy setting, selective CAM therapies (acupuncture, vegetarian diet, homeopathy, Tai Chi, Qi Gong, music-oriented and body-oriented therapies) can be recommended for a limited period of time.

[Colitis ulcerosa and opioid addiction]. / Opioidsucht bei Colitis ulcerosa.

The occurrence of an opioid addiction within an opioid treatment of pain or diarrhoea in inflammatory bowel disease is rarely reported. We report on a 36-year-old male with a 14 years lasting left sided chronic ulcerative colitis who developed after the initiation of a therapy with tincture of opium because of abdominal pain and diarrhoea an opioid addiction with the consumption of opium and later buprenorphin. Additionally to the diagnostics and therapy of the ulcerative colitis a detoxication was carried out. The diarrhoea slightly increased during the buprenorphin withdrawal. Diarrhoea refractory to other treatment should be treated by loperamid because of its lacking effects on the central nervous system. In chronic abdominal or musculoskeletal pain in inflammatory bowel disease opioids can be used if no surgical or other medical pain relief is possible. A consequent control of the therapeutic and side effects of the opioid therapy is necessary, especially of an abuse of opioid medication. The published case reports of a therapeutic induction of opioid addiction demonstrate that psychiatric comorbidity is an essential or even necessary risk factor. A checklist with seven criteria of opioid addiction during opioid therapy is presented.
