Options for Refractory axSpA or PsA

MedPage Today

Although most patients with axial spondyloarthritis (axSpA) or psoriatic arthritis (PsA) didn't respond adequately to the interleukin-17 (IL-17) inhibitor ixekizumab (Taltz), enough did that it should still be considered in such cases, a Danish registry study indicated.

Variability of Guidelines on the Perioperative Use of DMARDs in Rheumatic Diseases Patients

More effective treatments in patients with rheumatic diseases have resulted in less need for major surgery, yet a substantial number of RMD patients will undergo surgery often in the setting of DMARDs use. A scoping review looked at numerous clinical practice guidelines/recommendations for the

No Increased Malignancy Risk with Ixekizumab

A pooled analysis of 25 randomized clinical trials affirms the safety of ixekizumab (IXE) when used to treat patients with psoriasis (PsO), psoriatic arthritis (PsA), or axial spondyloarthritis (axSpA). The observed incidences of malignant neoplasms were consistent with the US general

Cancer Survival Outcomes in Autoimmune Skin Disease Patients

Patients with autoimmune skin diseases (ASDs) with cancer had significantly better cancer survival outcomes than those without ASD, suggesting coexistant autoimmune or inflammatory disease does not adversely affect a cancer prognosis.

ICYMI: Combination treatments in Psoriatic Arthritis

Despite the advances in the treatment of PsA with biologic (bDMARD) and targeted synthetic (tsDMARD), less than half of patients with this condition achieved remission or low disease activity. Combination DMARD treatment is often used in order to achieve remission or minimal disease activity.

Remission in Axial Spondyloarthritis Unrelated to Gut Inflammation

MedPage Today

Most patients with early, active axial spondyloarthritis (axSpA) who quickly received a tumor necrosis factor (TNF) inhibitor experienced remission, and it didn't matter whether or not they had intestinal inflammation at baseline, a small single-arm study found.
