Introduction:
Paediatric Crohn's disease is a disorder characterised by a chronic inflammation that can affect any part of the gastrointestinal tract. Intestinal dysbiosis is a key factor in the multifactorial pathogenesis of this disease. Different dietary supplements have been proposed as alternative therapy both on induction and on maintaining remission of this disease.
Objective:
To review current scientific evidence of intestinal dysbiosis in paediatric Crohn's disease patients, as well as efficacy of dietary supplement therapy (especially probiotics).
Materials And Methods:
Extensive search of scientific publications was performed in specialized electronic databases: NBCI, Elsevier, Scielo, Scirus and Science Direct.
Results And Discussion:
An increase of Proteobacteria and a reduction of Firmicutes were observed in Crohn's disease paediatric patients. However the results referring to phyla Bacteroidetes and Actinobacteria are disperse. Referring the use of dietary supplements, the use of probiotics did not show any positive impact in paediatric Crohn's disease patients.
Conclusions:
A better knowledge and understanding of the bacterial flora modifications in paediatric Crohn's disease patients is possible with the current published results. However, it is not possible to define the precise microbiota associated or causing this disease. In addition, current results do not bring solid evidence of the efficacy of probiotic therapy in those patients.

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.

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...

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...
