This study investigated the comorbidity burden of Swedish patients with palmoplantar pustulosis (PPP) vs. the general population and patients with psoriasis vulgaris (PV). We found a significantly higher comorbidity burden in patients with PPP compared with the general population, represented by higher odds for disease across different categories (metabolic, cerebrovascular, cardiovascular, psychiatric). Although patients with PPP and PV showed similar comorbidity burdens overall, the comorbidity profiles differed significantly. Comorbidities such as type 2 diabetes and chronic obstructive pulmonary disorder, which showed both high prevalence (> 5%) in PPP and higher odds than PV, may be of particular importance for the specific comorbidity burden of PPP.
