Background/Aim:
We previously found in Swedish patients with inflammatory bowel disease (IBD), crypts in symmetric fission (CSF) and in asymmetric fission (CAF). This study aimed to examine CSF and CAF in a cohort of German patients with IBD.
Patients And Methods:
H&E-sections from 106 IBD-patients [59 ulcerative colitis (UC) and 47 Crohn colitis (CCs)] were analysed.
Results:
A total of 588 crypts in fission (CF) were found; 342 (58.2%) in UC and 246 (41.8%) in CCs. Out of the 505 CAFs found, 304 (60.2%) were recorded in UC, and 201(39.8%) in CCs (p=0.15272).
Conclusion:
Despite that German and Swedish populations reside in disparate geographical regions with different ecological milieus, the proportions of CAF and CSF were similar, thereby suggesting that CAF and CSF develop in IBD independently of the local environmental conditions in the two regions.

Inflammatory Bowel Disease II: Crohn's Disease
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...

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...
Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory 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...
