Relapsing polychondritis, a rare inflammatory disorder that affects cartilaginous structures, presents challenges in diagnosis owing to overlapping symptoms with other conditions. This Review provides a clinical update on relapsing polychondritis, emphasizing the importance of distinguishing this disease from similar conditions.

Gout is associated with various cardiometabolic–renal comorbidities that increase the risk of mortality. Sodium–glucose cotransporter type 2 (SGLT2) inhibitors show promise in both addressing the symptoms of gout and managing relevant comorbidities to help prevent premature mortality.

In this Review, the authors describe shared pathophysiology of systemic juvenile idiopathic arthritis and adult-onset Still’s disease and their life-threatening complication, macrophage activation syndrome. Therapeutic developments now enable the targeting of multiple pathways in these conditions, and evidence suggests that early use of DMARDs has the potential to prevent chronic disease.

Medication adherence in gout is low, and discontinuation of urate-lowering therapy puts patients at risk of flares and cardiovascular events. A strategy to regularly monitor serum urate levels and the dissolution of urate deposits (particularly if visualized by patients) might encourage adherence in the long term.

For individuals with gout, the treatment options beyond conventional urate-lowering therapies are expanding. Notable advancements in 2023 include developments in uricase therapy, new xanthine oxidase inhibitors, and a class of medications that offer dual benefits for the control of type 2 diabetes mellitus and gout.

In a retrospective study, biologic DMARD therapy was associated with faster control of immune checkpoint inhibitor-associated arthritis but also with a shorter time to cancer progression, compared with methotrexate therapy.

Often viewed as merely an inconsequential episode of acute joint pain, gout flare has also been associated with an increased risk of acute myocardial infarction and stroke. New findings suggest the risk is highest within the first 60 days of gout flare, and could be influenced by flare treatment.
