Objectives:
This retrospective study aimed to investigate the clinical characteristics and genetic findings in paediatric patients with gastrointestinal involvement in Behçet's disease (BD), elucidating the spectrum of autoinflammatory syndromes mimicking BD in this young population.
Methods:
Fifty paediatric patients diagnosed with BD between January 2016 and December 2022, including 24 (48%) with gastrointestinal involvement, underwent comprehensive analysis. Clinical presentations, laboratory examinations, gastrointestinal endoscopy, and genetic tests were conducted, with patients stratified based on genetic results for rigorous comparative clinical analysis.
Results:
The cohort, with a median age of disease onset at 4.0 years, predominantly manifested with recurrent oral ulcers (100%). Gastrointestinal symptoms were prevalent in 83.3%, with abdominal pain (70%) and haematochezia (16.7%) being notable. Endoscopic evaluations unveiled lesions primarily in the terminal ileum and ileocecal region, with diverse ulcers across various anatomical sites. While 70.8% initially met ICBD criteria, only 41.6% fulfilled new paediatric classification criteria. Genetic analysis in 18 patients unveiled pathogenic variants in 7, with the genetic-positive group exhibiting earlier onset and more atypical symptoms. Noteworthy cases included X-linked deficiency in ELF4, A20 haploinsufficiency, and Majeed syndrome, with two cases revealing chromosomal abnormalities such as trisomy 8 syndrome. Comparative analysis underscored earlier disease onset, heightened inflammatory markers, and distinctive gastrointestinal lesions in the genetic-positive cohort.
Conclusions:
Identification of monogenic diseases and chromosomal abnormalities resembling BD underscores the imperative of precise diagnosis for tailored treatment and genetic counselling. Expanding genetic screening initiatives holds promise for enhancing our comprehension of the genetic landscape associated with BD.

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...
