[Microbiota markers level in the blood and cerebrospinal fluid of patients with different types of multiple sclerosis and radiologically isolated syndrome].

Objective: To assess the level of microbiota markers in the blood and cerebrospinal fluid (CSF) of patients with different types of multiple sclerosis (MS), people with radiologically isolated syndrome (RIS) and control subjects.

Material And Methods: We used gas chromatography-mass spectrometry (GC-MS) to evaluate the levels of microbiota markers in 69 patients with different types of MS (27 patients in the acute stage, 35 patients with MS in remission, 7 patients with primary-progressive MS), 10 people with RIS, and 47 control subjects (different diseases of the nervous system of a non-autoimmune or inflammatory nature).

Results: We showed a statistically significant increase in the content of various microbiota markers in the CSF of patients with MS compared with the control group.

Mesenchymal Stromal Cells as a Driver of Inflammaging.

Life expectancy and age-related diseases burden increased significantly over the past few decades. Age-related conditions are commonly discussed in a very limited paradigm of depleted cellular proliferation and maturation with exponential accumulation of senescent cells. However, most recent evidence showed that the majority of age-associated ailments, i.

Evaluation of the structure of the human microbiome in multiple sclerosis by the concentrations of microbial markers in the blood.

The relationship between multiple sclerosis and the state of the human microbiome was studied, namely, the change in the representation of microbiota phylotypes, the proportion of coccal flora, the proportion of anaerobic, gram-negative, proteolytically active microflora, as well as the concentration of markers of bacterial plasmalogen and endotoxin in the blood. Microbiome studies were carried out by gas chromatography - mass spectrometry of microbial markers in the blood. A statistically significant increase in blood concentrations of the total level of microbial markers of bacterial plasmalogen and endotoxin was determined in multiple sclerosis, which may be associated with an increase in the permeability of the intestinal wall.
