Gout is the most common inflammatory arthritis, which is characterized by elevated urate and monosodium urate (MSU) crystal deposition in tissues, leading to arthritis, soft-tissue masses (tophi), nephrolithiasis, and urate nephropathy. It has a major impact on health-related quality of life. The American College of Rheumatology (ACR) published ACR guidelines for the management of gout in June 2020, in which 42 recommendations (including 16 strong recommendations) were generated. The guideline described indications for urate-lowering therapy (ULT), approaches to initiating, ongoing management, gout flares, and lifestyle and other medication strategies in patients with gout and in individuals with asymptomatic hyperuricemia. This paper interprets it to provide references for clinical practice.
Psoriatic arthritis (PsA) is a disease with heterogeneous manifestations in patients who have manifest or latent psoriasis. It comprises both musculoskeletal and non-musculoskeletal manifestations. Active chronic PsA is often accompanied by cardiovascular, psychological and metabolic complications. Although the quantity of disease-modifying antirheumatic drugs (DMARDs) indicated for PsA has increased, clinicians still require some guidance in decision-making. Based on the latest evidence-based research results, the European League Against Rheumatism (EULAR) in 2019 developed the recommendations for the pharmacological management of PsA updated in 2015 with new recommendations. This paper interprets the update contents of the guideline to provide references for the clinical treatment of PsA.
