Background:
Inflammatory bowel disease (IBD) is a group of disorders, including Crohn's disease (CD), ulcerative colitis (UC) and indeterminate colitis (IC). Small intestine and colon are primarily affected in this group of disorders.
Purpose:
This single center study was performed to define demographic features and clinical characteristics of Iranian pediatric patients with IBD.
Method:
Fifty nine patients with IBD, who have been referred to Children's Medical Center Hospital during a 10-year period, were investigated in this study. The data was gathered by interviewing the patients and their families, as well as reviewing their medical records.
Results:
Among 59 patients with IBD, 23 cases had UC and 19 cases had CD, while the remaining 17 cases had IC. Patients with UC were significantly younger at the time of diagnosis in comparison with patients with CD. The most common symptoms were abdominal pain, diarrhea, fever and growth failure. Hepatobiliary abnormalities and arthritis were common extra intestinal manifestations. The median Pediatric Crohn's Disease Activity Index was 42.5 (range 20-60), whereas the median Pediatric Ulcerative Colitis Activity Index was 40 (range 20-70). Seven of 23 UC (30.4%) had proctatis, while 16 (69.6%) had extensive colitis. In CD, 11 of 19 (57.9%) had involvement of terminal ileum and colon, while inflammation was limited to the colon in 8 cases (42.1%). The colonoscopic findings in the IC group were heterogeneous.
Conclusion:
This study provides epidemiological data on pediatric patients with IBD, which could be useful for health care workers in prompt diagnosis and appropriate treatment of early onset IBD.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
