The microecological status of candidates for liver transplantation

A method for identifying mixed infections, dysbioses, and inflammatory processes from specific markers (fatty acids, aldehydes, and sterols) by chromatographic mass spectrometry was used to study the microecological status of patients eligible for liver transplantation. Heterogeneous microorganisms (aerobes, anaerobes, actinobacteria, fungi, and viruses) were quantified from molecular markers in an experiment within 3 hours after the samples were sent to the laboratory. The examinees were found to have excessive growth of gram-positive anaerobes (Clostridia, eubacteria), actinobacteria of the genera Streptomyces, Nocardia, and Candida yeasts. Next were staphylococci, streptococci, and gram-negative microorganisms of the group Moraxella/Acinetobacter, Pseudomonas aeruginosa, Helicobacter pylory, and Fusobacterium/Haemophylus. Antibiotics and probiotics were chosen to correct dysbiosis and infection, by taking into account the data available in the literature. The speed and accuracy of the procedure ensure real-time monitoring of a treatment process under control of mass spectrometry.
