AB0113 Efficacy of treatment with probiotics in the inflammatory activity of patients with rheumatoid arthritis. systematic review of the literature

Objectives To study the effectiveness of the use of probiotics in the control of inflammatory activity of patients with rheumatoid arthritis and analyse its effect on their metabolic profile. Methods A bibliographic search was carried out in Medline and Embase. The search strategy included the terms MeSH and the free text of ”lactobacillus”, ”bacillus”, ”probiotics” and ”rheumatoid arthritis.” The search strategies were carried out by two authors, which were included according to the type of studies: meta-analysis, systematic reviews and clinical trials, depending on the type of participant: adults with RA who have received probiotics, the main outcome measures: changes in the Disease Activity Score (DAS28), Simplified Disease Activity Index (SDAI) and Clinical Disease Activity Index (CDAI)), as well as each of the parameters that constitute them: C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), visual analogue scale of the doctor and the patient (EVA), number of painful joints (NAD) and inflamed (NAI) and functional status by Health Assessment Questionnaire (HAQ) Secondary variables: number of adverse events and parameters of metabolic activity. The quality of the evidence was analysed following the guidelines of the Scottish Network of Intercollegiate Guidelines (SIGN). Results After the selection of 34 articles, 9 articles were finally included. All were randomised, double-blind, placebo-controlled clinical trials (RCTs) with a level of evidence between 1+and 1++and a recommendation grade of A and B. Seven CDs showed improvement in arthritis measurements. In Peltonen et al. observed a high rate of improvement in the experimental group than in the control group (3.1 vs 2, p=0.027). Mandel et al. they described improvement of the EVA in the experimental group (p=0.046). Zamani the al. they described an improvement in DAS28 (−0.3±0.4 versus −0.1±0.4, p=0.01). Vaghef-Mehrabany et al defined this improvement (p Conclusions Treatment with probiotics seems to be effective in controlling the inflammatory activity of rheumatoid arthritis.
