Impact of herbs and dietary supplements in patients with fibromyalgia: A protocol for a systematic review and meta-analysis of randomized controlled trials.

ABSTRACT

BACKGROUND: Fibromyalgia (FM) is a common chronic pain condition that seriously affects the quality of patient lives. Its etiology, pathogenesis, and treatment still remain uncertain. Dietary supplements have been widely trialed for symptom relief for FM. The review aims to synthesize the previous literature publications to assess the impact of herbs and dietary supplements on FM patients. METHODS: We will conduct a literature search in the following databases PubMed, MEDLINE, EMBASE, Cochrane Library, Scopus, and Global Health from database inception to December 2019. Clinical studies published in the English language that used human participants and address the efficacy, safety, and acceptability of herbs and dietary supplements on individuals with FM will be included. The risk of bias and quality assessment of each trial will be evaluated. If trials are enough, a meta-analysis will be conducted using software RevMan5.3, Cochrane Collaboration. RESULT: Our review will be the first attempt to facilitate evidence-based management using herbs and dietary supplements to treat patients with FM. CONCLUSION: The findings may provide a framework for future research and clinic practice in FM management. PROSPERO REGISTRATION NUMBER CRD42020149941.
