Through a retrospective study, it was found that patients with acne keloidalis nuchae (AKN) have an increased risk of developing gout compared to control subjects. However, after controlling for other confounders, the increased risk of gout associated with AKN was not significant.
Background The risk of gout amid patients with acne keloidalis nuchae (AKN) has not been investigated in the past. Objective To assess the risk of developing gout among patients with AKN relative to control subjects. Methods A population-based retrospective study followed patients with AKN (n = 2677) and age-, sex-, and ethnicity-matched control subjects (n = 13 190). The incidence of new-onset gout was compared between the two groups. Hazard ratio (HR) for the risk of gout was obtained using a multivariate Cox regression model. Results 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.
