Psoriasis and inflammatory bowel disease (IBD), including Crohn's disease, share common genetic and inflammatory pathways. Although more research is needed to fully elucidate this association, several studies have observed an increased prevalence of IBD, particularly Crohn's disease, in patients with psoriasis.
An increased risk for respiratory, abdominal, and skin infections has been observed among patients with psoriasis. Those patients tend to have more severe skin disease and are at increased risk for severe liver fibrosis compared with patients without psoriasis.
Studies have noted an increased incidence of nonalcoholic fatty liver disease among patients with psoriasis.
