Abstract
Abstract Objectives People with gout exhibit significant clinical heterogeneity due to diverse comorbidity profiles. This study aimed to identify distinct clinical phenotypes using cluster analysis and to evaluate differences in management, specifically urate-lowering therapy (ULT) patterns and sustained serum urate (SU) control. Methods A population-based retrospective cohort study was conducted using the SIDIAP database (Catalonia, Spain), including 94,759 patients with incident gout (2012–2023). A K-prototypes algorithm identified clusters based on demographics and major comorbidities. Outcomes included sustained SU control (defined as SU < 6 mg/dL for ≥80% of the follow-up time) and ULT adherence (Medication Possession Ratio, MPR). Results Three distinct clusters were identified. Cluster 1 (37.0%) was comprised of younger patients (mean age 54) with fewer comorbidities and the highest SU control. Cluster 2 (22.8%) included older patients (mean age 74) characterized by 100% type 2 diabetes prevalence, high obesity (51.3%), and the greatest cardiovascular burden. Cluster 3 (40.2%) featured older patients with hypertension and dyslipidaemia but no diabetes. Overall, management was suboptimal in all groups; only 12% of patients achieved sustained SU control. While Cluster 2 had higher ULT prescription rates, Cluster 1 showed better adherence and SU control. Conclusion Gout manifests in three clearly differentiated clinical phenotypes, each potentially reflecting a distinct predominant aetiology of hyperuricaemia (isolated/genetic, insulin-resistance-mediated, or renal-vascular). The identification of these high-risk metabolic and hypertensive clusters underscores the need for comorbidity-driven management and tailored therapeutic strategies.
