Brief description

Gout is a urate crystal deposition disease that can manifest as a recurrent acute arthritis, usually involving a single joint, with asymptomatic periods between attacks.  It may also manifest as chronic tophaceous gout, with arthropathy and deposition of solid urate in connective tissues, and associated inflammation and tissue destruction.

Confirming the diagnosis

Diagnosis is based on a combination of clinical, laboratory and imaging findings.  In the case of acute gout this should include analysis of joint fluid for the presence of urate crystals.  The diagnosis can be made by a general practitioner.

The relevant medical specialist is a rheumatologist.

Non-SOP condition

Clinical onset

Clinical onset will generally correspond with a first acute arthritis episode, subsequently confirmed to be due to gout.

Clinical worsening

Gout can be successfully managed with medications and lifestyle changes directed at lowering urate levels. Treament can significantly reduce the development of chronic gouty arthritis and tophaceous gout. Progression of disease may indicate non-compliance with treatment.
