[Definition, diagnostics and therapy of chronic widespread pain and the (so-called) fibromyalgia syndrome in children and adolescents : Updated guidelines 2017].

BACKGROUND: The regular update of the guidelines on fibromyalgia syndrome, AWMF number 145/004, was scheduled for April 2017.
METHODS: The guidelines were developed by 13 scientific societies and 2 patient self-help organizations coordinated by the German Pain Society. Working groups (n = 8) with a total of 42 members were formed balanced with respect to gender, medical expertise, position in the medical or scientific hierarchy and potential conflicts of interest. A search of the literature for case series (cross-sectional- and longitudinal studies) for the topics diagnosis, etiology and pathophysiology and for randomised controlled trials (RCT) for treatment modalities from December 2010 to May 2016 was performed in the Cochrane library, MEDLINE, PsycINFO and Scopus databases. Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine version 2009. The strength of recommendations was achieved by multiple step formalized procedures to reach a consensus. Efficacy, risks, patient preferences and applicability of available therapies were weighed up against each other. The guidelines were reviewed and approved by the board of directors of the societies engaged in the development of the guidelines. RESULTS AND
CONCLUSION: No consensus was achieved in the guideline group on whether the diagnostic label "juvenile fibromyalgia" should be used in the management of children and adolescents with chronic widespread pain. There was consensus in the guideline group that antidepressants and anticonvulsants should not be used to treat pain in the so-called juvenile fibromyalgia syndrome.
