Predictors of disease behavior change in Crohn's disease

World Journal of Gastroenterology

Using the Vienna classification system, it has been shown in clinic-based cohorts that there can be a significant change in disease behavior over time, whereas disease location remains relatively stable. Clinical and environmental factors as well as medical therapy might be relevant in predicting disease behavior change in patients with CD. In previous studies, early age at diagnosis, disease location, perianal disease and, in some studies, smoking were associated with the presence of complicated disease and surgery.

The combined effect of markers of disease phenotype (e.g., age, gender, location, perianal diesease) and medical therapy (steroid use, early immunosupression) on the probability of disease behavior change were, however, not studied thus far in the published literature.

A research article to be published on July 28, 2009 in the World Journal of Gastroenterology addresses this question. Members of the Hungarian IBD Study Group led by Dr Peter Laszlo Lakatos from the Semmelweis University investigated 340 well-characterized, unrelated, consecutive CD patients (M/F: 155/185, duration: 9.4 ± 7.5 years) with a complete clinical follow-up. Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively. Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits.

They found that perianal disease, current smoking, prior steroid use, early azathioprine or azathioprine/biological therapy are predictors of disease behavior change in CD patients.

The new data with easily applicable clinical information as presented in the article may assist clinicians in practical decision-making or in choosing the treatment strategy for their CD patients.
