The differences between American and Chinese patients with Crohn's disease

Area of Science:

• Gastroenterology
• Internal Medicine
• Epidemiology

Background:

• The impact of race on Crohn's disease (CD) presentation and severity is not well-established.
• Understanding these differences is crucial for tailored patient management and treatment strategies.

Purpose of the Study:

• To compare the clinical characteristics and pathological involvement of colorectal Crohn's disease (CD) between American white patients and Chinese patients.
• To identify potential disparities in disease presentation based on race.

Main Methods:

• A retrospective chart review was performed on 153 patients with colorectal CD.
• Data collected included patient demographics, family history, smoking status, disease location, and histopathology.
• Patients were drawn from Cleveland Clinic Florida and the 301 Hospital in China between 1985 and 2004.

Main Results:

• American white patients presented with significantly higher rates of arthritis, abscess, rectal/perineal fistulas, and more extensive colorectal involvement compared to Chinese patients.
• Chinese patients exhibited a higher prevalence of ileocecal disease and deep ulcers in the colorectum.
• While women constituted a larger proportion of American white CD patients, a family history of CD was more common in this group.

Conclusions:

• Colorectal Crohn's disease (CD) demonstrates a more severe clinical and pathological profile in American white patients compared to Chinese patients.
• Significant differences in disease location, extraintestinal manifestations, and specific pathological features were observed between the two racial groups.
