ABSTRACT
BACKGROUND AND AIMS: Perianal lesion is a refractory phenotype of Crohn’s disease (CD) with significantly diminished quality of life. We evaluated the clinical characteristics of perianal lesions in newly diagnosed CD patients and the impact of perianal lesions on the quality of life in Japanese patients with CD.
METHODS: Patients newly diagnosed with CD after June 2016 were included between December 2018 and June 2020 from the Inception Cohort Registry Study of Patients with CD (iCREST-CD).
RESULTS: Perianal lesions were present in 324 (48.2%) of 672 patients with newly diagnosed CD. 71.9% (233/324) were male. The prevalence of perianal lesions was higher in patients aged <40 years versus ≥40 years, and it decreased with age. Perianal fistula (59.9%) and abscess (30.6%) were the most common perianal lesions. In multivariate analyses, male sex, age <40 years, and ileocolonic disease location were significantly associated with a high prevalence of perianal lesions, whereas stricturing behaviour and alcohol intake were associated with low prevalence. Fatigue was more frequent (33.3% vs 21.6%) and, work productivity and activity impairment-work time missed (36.3% vs 29.5%) and activity impairment (51.9% vs 41.1%) were numerically higher in patients with than those without perianal lesions.
CONCLUSIONS: At the time of CD diagnosis, approximately half of the patients had perianal lesions; perianal abscesses and perianal fistulas were the most common. Young age, male sex, disease location, and behaviour are significantly associated with the presence of perianal lesions. The presence of perianal lesion was associated with fatigue and impairment of daily activities.
