Sumario:BACKGROUND: Previous research has pointed to the relationship between psoriasis and the development of gout. However, most previous studies had either small sample sizes or short study durations. Therefore, in this nationwide cohort study, we investigated the effect of psoriasis on the risk of gout development. METHODS: The study group included one million patients from Taiwan, whom we followed for 14 years. The participants were divided into two cohorts designated as psoriasis and non-psoriasis. A 1:4 propensity score matching test was used to compare age, sex, and index year between the two cohorts. Cox proportional hazard regression was used to determine the hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk of gout. Sensitivity analyses were conducted to evaluate the HR for gout after the occurrence of psoriasis. RESULTS: The incidence densities of gout in the psoriasis and non-psoriasis cohorts were 6.96 and 5.09 per 1000 person-years, respectively. After adjusting for age, sex, urbanization, comorbidities, and nonsteroidal anti-inflammatory drug (NSAID) use, the adjusted hazard ratio (aHR) with 95% CI for incidental gout in the psoriasis group was 1.38 (1.2–1.6). Moreover, the aHR (95% CI) values for gout risk in patients with psoriasis using NSAIDs and those who did not were 1.21 (1.0–1.47) and 1.65 (1.33–2.05), respectively. CONCLUSION: This study demonstrated an association between psoriasis and risk of developing gout. Clinically, patients with psoriasis should be evaluated for incidental gout.
