Biologics in Inflammatory and Immunomediated Arthritis.

BACKGROUND: Biologic drugs, introduced in clinical practice almost twenty years ago, represent nowadays a prominent treatment option in patients with chronic inflammatory arthritis, such as Rheumatoid Arthritis, Psoriatic Arthritis and Spondyloarthritis, that include ankylosing spondylitis and non-radiographic axial spondyloarthritis.
METHODS: Several compounds targeting different pathways have been marketed and approved for the treatment of inflammatory arthritis, with a significant impact on the clinical outcomes and the natural history of the diseases.
RESULTS: There are currently seven classes of biologics that are available for the treatment of inflammatory arthritis, each inhibiting a different aspect of the immune-driven inflammatory pathway. They include: • Tumor Necrosis Factor (TNF) inhibitors (infliximab, adalimumab, etanercept, golimumab and certolizumab pegol); • Interleukin-1 (IL-1) receptor antagonists (anakinra); • Interleukin-6 (IL-6) inhibition (tocilizumab); • Interleukin-12/23 (IL23) inhibition (ustekinumab); • Interleukin-17 (IL-17) inhibition (secukinumab); • B-cell inhibition (anti-CD20, rituximab); • T-cell costimulation inhibition (anti-CTLA-4, abatacept).
CONCLUSION: In this review, we will focus on the role of biologic drugs in the treatment strategies for inflammatory arthritis. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.
