[Gout: an overview of diagnostics and treatment]

Gout is characterized by acute arthritis due to the deposition of urate crystals in joints in a state of hyperuricemia. Gout is a clinical diagnosis and can be confirmed with a joint aspiration to examine the synovial fluid with a polarized light microscopy. If a joint aspiration is not feasible or inconclusive, ultrasound or Dual Energy Computed Tomography (DECT) can be considered. Pharmacological treatment of gout consists of treating acute flares with anti-inflammatory drugs and, if indicated, of urate lowering therapies (ULT). (Inter)national rheumatology guidelines recommend the use of ULT indefinite by a treat-to-target approach, but there is discussion whether (certain) patients might also be treated by a treat-to-avoid-symptoms approach. Two large Dutch trials are comparing these strategies in gout patients. Most gout patients have cardiovascular and metabolic comorbidities and therefore an indication for cardiovascular risk assessment.
