During this phase, the body attempts to isolate the persistent MSU crystals by forming granulomatous structures known as tophi. The chronic inflammation associated with tophi can lead to erosions in the bone and cartilage, resulting in permanent joint deformity and a significant loss of function, underscoring the importance of sustained urate-lowering therapy.

Chronic Phase and Tophi Formation If hyperuricemia persists over the long term, the acute inflammatory process can evolve into a chronic state. 8 mg/dL at 37°C, the solubility limit of uric acid.
Gout pathophysiology centers on the complex interplay between purine metabolism, urate crystal formation, and the host inflammatory response. The Role of the Innate Immune System Once MSU crystals are deposited in the joint space or synovial lining, they are engulfed by immune cells, primarily neutrophils and macrophages.

While this represents an attempt to wall off the irritant, it ultimately contributes to tissue damage and joint destruction. Genetic polymorphisms affecting urate transporters, such as URAT1 and ABCG2, play a major role in renal handling of uric acid, explaining why some individuals are overproducers while others are underexcretors.
