The impact of targeted Rheumatoid Arthritis pharmacological treatment on mental health: A systematic review and network meta-analysis Thumbnail


Abstract

Rheumatoid Arthritis (RA) pharmacotherapy may impact mental health (MH) outcomes by improving pain and stiffness; and potentially via targeting inflammatory processes common to RA and depression. The objectives of this review were to i) ascertain the frequency of MH assessment in RA pharmacotherapy trials; ii) quantify the efficacy of RA pharmacotherapy efficacy on MH outcomes; iii) explore the clinical and demographic factors related to MH outcomes.

CENTRAL, PsychINFO, Web of Science, Medline, Embase and CINAHL were systematically searched from inception to March 2017 for randomised trials of disease-modifying anti-rheumatic drugs (DMARDs) in adult RA patients. The primary outcome was MH; self-reported physical health was extracted as a secondary outcome. Pairwise meta-analysis (PMA) created pooled effect sizes and 95%CIs for comparisons of all treatments versus comparators (active or placebo). Network meta-analysis (NMA) provided effect size estimates of targeted biologic DMARDs (bDMARDs) versus conventional synthetic DMARDs (csDMARDs) using indirect comparisons of different treatment modalities.

71 eligible studies were identified. 57 studies were included in the PMA, representing 23,535 patients. bDMARDs showed small effects on MH (standardised mean difference (SMD) versus csDMARDs = 0.19 to 0.30), and moderate effects on self-reported physical health (SMD versus csDMARDs = 0.46 to 0.50), with NMA determining no significant differences in effectiveness between bDMARD mode of action on either outcome.

Effective pharmacotherapy alone is unlikely to substantially improve MH outcomes for most RA patients. Integrated MH care provided within routine clinical practice is essential to optimise mental and physical health outcomes.
