Inflammatory Bowel Disease in Children and Adolescents – a Retrospective Study of 13 Years of Records Investigating Potential Prognostic Factors

Purpose: To assess the landscape of management of pediatric inflammatory bowel disease (IBD) patients in Greece and investigate possible prognostic factors for the disease outcome. Method: The medical records of all IBD patients who visited the gastroenterology divisions of two university pediatric clinics as in- or outpatients over 13 years were examined. Results: Twenty-seven females and 25 males were included in the study. Ulcerative colitis (UC) was diagnosed in 46% of cases, Crohn’s Disease (CD) in 33% and unclassified IBD (IBD-U) remained the diagnosis in 21%. The CRP level was elevated in 68% of cases at diagnosis, whereas only 27.4% of patients had ESR levels and platelet counts within the age-adjusted normal range. No parameter derived from patient history, physical examination or laboratory and imaging was found to influence the time to diagnosis. Abdominal pain and lack of diarrhea at the time of diagnosis were significantly associated with the need for biologic therapy during the disease course in CD. Consistent with the “step-up” approach the treating physicians practiced, an increased number of relapses correlated with the addition of biologics in the treatment of both CD and UC patients (P=.03 and P=.002, respectively). Conclusion: It is the first time that clinical data regarding IBD pediatric patients in Greece were reviewed. Some clinical and imaging factors were associated with more aggressive disease, an increased need for biological treatment and frequent hospitalizations for IBD flares. Moreover, it was observed that the clinical features of IBD in Greek children were similar to those in other countries.
