Summary

Gut microbiome research has been a surge of interest in many branches of medicine in the last decade. Our main aim is to show ability of microbes to infuence the functions of human body, especially in the immune system, and on the other hand to clarify changes in composition of gut microbiome in the post-transplantation period and their function for the long-term survival of the graft and the patient in the context of the occurrence of a wide range of complications.

Kidney transplantation with the subsequent use of immunosuppressants and antibiotics affects the composition of gut microbiome. The subsequent development of dysbiosis significantly increases the risk of acute rejection, interstitial fibrosis and tubular atrophy of the graft, post-transplant diarrhoea, organ´s infections and metabolic complications such as post-transplant diabetes mellitus.

Also important is the influence of the microorganisms of the gut microbiome on metabolism of immunosuppressants with the production of less effective components and the subsequent necessity of modifying their levels with a higher risk of underdosing and the occurrence of graft rejection. Support of the composition of the gut microbiome in the post-transplantation period in favor of bacteria producing short chain fatty acids (SCFA) is possible by changing of diet with predominance of fiber, the application of probiotics, prebiotics.

According to available studies, it can lead to benefits in term of metabolic compensation, to the induction of donor-specific tolerance and many others, with an overall improvement in the quality of patient and graft survival.
