[The volatile fatty acids in children with dysfunction of biliary tract]
Insights
Children with biliary tract dysfunction show altered volatile fatty acids in saliva, indicating potential bacterial imbalances. These salivary markers may aid in diagnosing pediatric biliary conditions.
Area of Science:
- Microbiology
- Gastroenterology
- Pediatrics
Background:
- Volatile fatty acids (VFAs) are bacterial metabolites reflecting gastrointestinal microflora status.
- Dysbiotic alterations in gut microbiota are linked to various health conditions.
Purpose of the Study:
- To qualitatively determine volatile fatty acids in the saliva of children with biliary tract dysfunction.
- To compare VFA profiles between children with and without biliary tract dysfunction.
Main Methods:
- Analysis of VFAs in saliva samples from 46 children (7-17 years) with biliary tract dysfunction and 34 healthy controls.
- Qualitative detection of acetic, butyric, and isovaleric acids using gas-liquid chromatography (automated gas chromatograph 'Crystal deluxe 4000', capillary column 'HP-FFAP', flame ionizing detector).
Main Results:
- Children with biliary tract dysfunction exhibited a decreased anaerobic index.
- Elevated levels of acetic and propionic acids, along with a higher sum of VFAs, were observed in the saliva of children with biliary tract dysfunction compared to healthy controls.
Conclusions:
- Bacterial metabolites, including VFAs, may play a role in the pathogenesis of biliary tract dysfunction in children.
- Salivary VFA profiles offer potential as novel diagnostic criteria for pediatric biliary tract dysfunction.
Abstract:
The volatile fatty acids are metabolites of bacteria reflecting condition and disbiotic alterations of microflora of gastrointestinal tract. The study was carried out to determine qualitatively volatile fatty acids in saliva of children with dysfunction of biliary tract and healthy ones. The indices of volatile fatty acids were analyzed in 46 children aged 7-17 years and with dysfunction of biliary tract. The comparison group included 34 healthy children aged from 7 to 17 years. The gas-liquid chromatography was applied to qualitatively detect acetic, butyric, isovaleric acids (volatile fatty acids). The automatedgas chromatograph "Crystal deluxe 4000" with capillary column "HP-FFAP" and flame ionizing detector was used. The study established decreasing of anaerobic index, increasing of acetic, propionic acids and sum of volatile fatty acids in saliva of children of main group as opposed to children of comparison group. The possible role of bacterial metabolites and bacteria in pathogenesis of dysfunction of biliary tract in children. The description is made of one of possible mechanisms of increasing of volatile fatty acids in saliva under dysfunction of biliary tract. The integral indices of volatile fatty acids of saliva are the new additional criteria for diagnostic of dysfunction of biliary tract in children.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
