About this Research Topic
Gout is associated with significant increases in morbidity and mortality. Independent associations have been demonstrated with several comorbidities including atherosclerotic disease, renal failure, atrial fibrillation, and more, yet the underlying link remains to be established. Monosodium urate (MSU) crystals - the cornerstone of gout - are found in joints and periarticular structures, leading to acute attacks, joint damage and tophi. Anecdotally, these crystals are also found in other tissues such as the cardiovascular tree, renal medulla, and gut, and could thus explain the link between gout and its varying comorbidities. Advanced imaging - in particular high-resolution ultrasound and dual-energy CT – has proven useful to identify and quantify MSU crystal deposits, and preliminary works indicate a potential for assessing this non-musculoskeletal deposition.
Further research in this area is highly required in order to establish whether:
1) MSU crystal deposition is constant;
2) MSU crystal deposition exerts a pathogenic role in the extra-articular system (especially as crystal deposition is reversible with proper control of hyperuricemia);
3) Local and systemic MSU-driven inflammation, or other mechanisms, contribute to the occurrence of morbidity and mortality in gout.
In this Research Topic, we call for laboratory, translational and clinical research aiming to increase knowledge in the aforementioned areas.
