1 Review Exploring the Link between Uric Acid and Osteoarthritis. 2017

Ma, Cheryl Ann / Leung, Ying Ying. ·Duke-NUS Medical School, Singapore, Singapore. · Department of Rheumatology and Immunology, Singapore General Hospital, Singapore, Singapore. ·Front Med (Lausanne) · Pubmed #29326934.

ABSTRACT: Both gout and osteoarthritis (OA) are common forms of arthritis that inflict a huge burden to an aging population with the increasing prevalence of obesity. Clinicians have long observed the link between these two conditions. In this review, we summarize the evidence from epidemiologic and immunological studies that described the possible relationship between the two conditions. The recent new understanding on monosodium uric acid crystal-induced inflammation has given insight into probable shared pathogenesis pathways for both conditions. We describe the potential therapeutic implications, particularly regarding the possibility of repurposing traditional gout medications for use in OA.

ABSTRACT: OBJECTIVES: To review the literature and provide an update on the mechanisms of action and therapeutic uses of oral colchicine in arthritis and inflammatory conditions. METHODS: We performed PubMed database searches through June 2014 for relevant studies in the English literature published since the last update of colchicine in 2008. Searches encompassed colchicine mechanisms of action and clinical applications in medical conditions. A total of 381 articles were reviewed. RESULTS: The primary mechanism of action of colchicine is tubulin disruption. This leads to subsequent down regulation of multiple inflammatory pathways and modulation of innate immunity. Newly described mechanisms include various inhibitory effects on macrophages including the inhibition of the NACHT-LRRPYD-containing protein 3 (NALP3) inflammasome, inhibition of pore formation activated by purinergic receptors P2X7 and P2X2, and stimulation of dendritic cell maturation and antigen presentation. Colchicine also has anti-fibrotic activities and various effects on endothelial function. The therapeutic use of colchicine has extended beyond gouty arthritis and familial Mediterranean fever, to osteoarthritis, pericarditis, and atherosclerosis. CONCLUSION: Further understanding of the mechanisms of action underlying the therapeutic efficacy of colchicine will lead to its potential use in a variety of conditions.

ABSTRACT: OBJECTIVE: While cross-sectional and retrospective case-control studies suggest that gout is associated with knee osteoarthritis (KOA), no prospective study has evaluated the risk of total knee replacement (TKR) for KOA in association with gout. We prospectively evaluated the association between gout and the risk of TKR due to severe KOA. DESIGN: We used data from the Singapore Chinese Health Study (SCHS), a prospective cohort with 63,257 Chinese adults aged 45-74 years at recruitment (1993-1998). Self-report of physician-diagnosed gout was enquired at follow-up I interview (1999-2004) from 52,322 subjects. TKR cases for KOA after follow-up I were identified via linkage with nationwide hospital discharge database through 31 December 2011. Multivariable Cox proportional hazards regression model was applied with adjustment for potential risk factors of KOA. RESULTS: Among 51,858 subjects (22,180 men and 29,678 women) included in this analysis, after average 9.7 follow-up years, there were 1,435 cases of TKR. Gout was associated with 39% higher risk of TKR in women [hazard ratio (HR) 1.39; 95% confidence interval (CI) 1.08-1.79] but not in men (HR 0.78; 95% CI 0.49-1.23). The positive gout-TKR association in women remained after excluding participants with self-reported history of arthritis (HR 1.57; 95% CI 1.04-2.37). This association was stronger in women who were lean (body mass index [BMI] < 23 kg/m CONCLUSION: Gout is associated with risk of severe KOA, especially in lean women, suggesting the crystal arthritis may play a role in the pathogenesis or progression of OA.
