The burden of gout in acne keloidalis nuchae-Insights from a population-based study.

The incidence rate of gout was 1.12 (95% CI, 0.68-1.76) and 0.48 (95% CI, 0.34-0.66) per 1000 person-years among patients with AKN and controls, respectively. The crude risk of developing gout was significantly higher in patients with AKN (HR, 2.27; 95% CI, 1.26-4.10; p = 0.007). After controlling for age, sex, and ethnicity, AKN emerged as an independent risk factor of gout (adjusted HR, 2.34; 95% CI, 1.29-4.22; p = 0.005). When adjusting for other confounders such as body mass index, diabetes mellitus, hypertension, and dyslipidemia, the risk of gout in AKN fell out of significance (adjusted HR, 1.39; 95% CI, 0.73-2.65; p = 0.311), CONCLUSION: Patients with AKN experience an increased risk of gout. The risk is not independent and is mainly mediated through the metabolic comorbidities typifying AKN. We recommend screening for gout in patients with suggestive complaints.
