title: Hyperuricaemia with deposition: latest evidence and therapeutic approach.
abstract: This article reviews recent evidence on urate deposition and the opportunity for a therapeutic approach. We reviewed Pubmed 2013-2015 literature using the search terms 'deposition' with 'hyperuricaemia', 'gout', 'ultrasonography', 'DECT' (dual-energy computed tomography), 'radiography', 'CT'(computed tomography), 'MRI' (magnetic resonance imaging), or 'cardiovascular', in addition to a digital bibliographic library compiled by the authors with 2072 papers on hyperuricaemia and gout. Relevant papers on the topic were selected. Recent evidence, mostly based on imaging studies, showed a continuum from hyperuricaemia to deposition and clinical manifestations. Chronic inflammation and structural damage may be present even in asymptomatic patients with crystal-proved deposition. The impact of early intervention in patients with asymptomatic deposition either on vascular outcomes or further structural joint damage has not been demonstrated yet. In conclusion, a worldwide definition of gout is still lacking, stages from hyperuricaemia to clinical gout not being definitively defined. Although there is increasing interest on the impact of early deposits on joint damage and cardiovascular outcomes, robust evidence is still lacking to fully support interventions.
