Insights
Pediatric inflammatory bowel disease (IBD) is increasing in Poland, with a nearly 50% rise in diagnoses over six years. Ulcerative colitis (UC) shows a significant increase in pediatric cases, highlighting a growing public health concern.
Area of Science:
- Pediatric Gastroenterology
- Epidemiology
- Inflammatory Bowel Disease Research
Background:
- Pediatric inflammatory bowel disease (IBD) incidence is rising globally.
- Epidemiological data is crucial for managing IBD burden in children and adolescents.
- Limited data exists on pediatric IBD trends in Poland's Kujawsko-Pomorskie Voivodeship.
Purpose of the Study:
- To evaluate the incidence of pediatric IBD from 2011 to 2022.
- To compare trends of ulcerative colitis (UC), Crohn's disease (CD), and unclassified IBD (IBD-U) between 2011-2016 and 2017-2022.
Main Methods:
- Retrospective analysis of 118 pediatric IBD patients.
- Data collected from the Department of Pediatrics, Allergology and Gastroenterology in central-northern Poland.
Main Results:
- IBD diagnoses increased significantly from 48 (2011-2016) to 70 (2017-2022).
- Ulcerative colitis (UC) incidence doubled, showing a significant increase (P=0.015).
- Crohn's disease (CD) incidence did not show a significant increase.
Conclusions:
- Pediatric IBD incidence in this region of Poland is increasing, particularly for UC.
- The number of pediatric IBD diagnoses rose by nearly 50% in the last six years.
- Further research is needed to understand regional IBD trends and inform public health strategies.
Background:
Many of the patients with inflammatory bowel disease (IBD) are children and adolescents, and the incidence of pediatric IBD is increasing. However, understanding epidemiological trends is crucial for effective prevention and treatment and reducing the local and global burden of IBD. Little data exist regarding the incidence of IBD in the child population in the Kujawsko-Pomorskie Voivodeship. The aims of this study were to evaluate the incidence of IBD in the period 2011 - 2022 and to compare the data regarding three types of IBD, namely ulcerative colitis (UC), Crohn's disease (CD), and unclassified inflammatory bowel disease (IBD-U), from the first half, i.e. 2011 - 2016, to the second half, i.e. 2017 - 2022.
Methods:
This retrospective study analyzed the medical records of 118 IBD patients hospitalized at the Department of Pediatrics, Allergology and Gastroenterology from the central-northern part of Poland.
Results:
Of the 118 patients diagnosed with IBD, 48 (40.68%) had CD, 57 (48.31%) had UC, and 13 (11.01%) had IBD-U. Between 2011 and 2016, 48 new IBD patients were diagnosed, with a further 70 new cases added between 2017 and 2022, representing a significant increase over the period (P = 0.033). Also, a significant increase was seen for UC, i.e. rising from 19 new cases between 2011 and 2016, to 38 between 2017 and 2022 (P = 0.015). The increase in CD was not significant.
Conclusion:
The incidence of pediatric IBD in the central-northern district of Poland is lower than other countries, it nonetheless appears to be increasing, particularly in children with UC. The number of IBD diagnoses in children has increased by nearly 50% over the last 6 years.

01:30Inflammatory 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...
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...
