Summary of "Efficacy and safety of systemic treatments in psoriatic arthritis. A systematic review, meta-analysis and GRADE evaluation."

Twenty percent of patients with plaque psoriasis also have psoriatic arthritis - a disease affecting joints and entheses. Different treatment options exist but currently no succinct systematic overview exists. A systematic review of approved systemic treatments for psoriatic arthritis was conducted. We systematically searched in 3 databases (last update 09/2017). Data was extracted for ACR 20/50, HAQ-DI, SF-36 and adverse/serious adverse events after 16-24 weeks. We assessed the quality of evidence using GRADE. Twenty trials were included. Three trials compared two active substances. Results for ACR20 were infliximab+methotrexate vs. methotrexate: RR 1.40 (95%CI 1.07 to 1.84) very low quality evidence; ixekizumab Q2W vs adalimumab Q2
RR 1.08 (95%CI 0.86 to 1.36) very low quality, leflunomide vs. methotrexate: RR 1.01, (95%CI 0.84 to 1.21) low quality. Eighteen drug vs. placebo-comparisons were included. For ACR20/50, HAQ-DI and SF-36, the active treatment was efficacious and the quality of the evidence was mostly moderate to low (15 of 18 comparisons). The quality of evidence for (serious) adverse events was mostly low; differences were rare. In three placebo-controlled comparisons leflunomide, MTX and sulfasalazine failed to show statistical superiority for ACR. Besides the established treatment of anti TNF antibodies und ustekinumab for psoriatic arthritis, the newer treatment options of IL17 antibodies and apremilast are also effective for the treatment of psoriatic arthritis. Based on just one comparative trial and one drug each, the new class of anti IL 17 antibodies appears to be equally effective as the group of anti TNF antibodies, for apremilast this is yet unclear.

Medical and Biotech [MESH] Definitions

Multi-step systematic review process used for improving safety by investigation of incidents to find what happened, why it happened, and to determine what can be done to prevent it from happening again.

A chimeric monoclonal antibody to TNF ALPHA that is used in the treatment of RHEUMATOID ARTHRITIS; ANKYLOSING SPONDYLITIS; PSORIATIC ARTHRITIS and CROHN'S DISEASE.

A humanized monoclonal antibody that binds specifically to TNF-ALPHA and blocks its interaction with endogenous TNF RECEPTORS to modulate INFLAMMATION. It is used in the treatment of RHEUMATOID ARTHRITIS; PSORIATIC ARTHRITIS; CROHN'S DISEASE and ULCERATIVE COLITIS.

A type of inflammatory arthritis associated with PSORIASIS, often involving the axial joints and the peripheral terminal interphalangeal joints. It is characterized by the presence of HLA-B27-associated SPONDYLARTHROPATHY, and the absence of rheumatoid factor.

A recombinant version of soluble human TNF receptor that binds specifically to TUMOR NECROSIS FACTOR and inhibits its binding with endogenous TNF receptors. It prevents the inflammatory effect of TNF and is used to treat RHEUMATOID ARTHRITIS; PSORIATIC ARTHRITIS and ANKYLOSING SPONDYLITIS.
