Cancer and Autoimmune Diseases as Two Sides of Chronic Inflammation and the Method of Therapy.

Chronic inflammation is associated with a prolonged increase in various inflammatory factors. According to clinical data, it can be linked with both cancer and autoimmune diseases in the same patients. This raises the critical question of how chronic inflammation relates to seemingly opposing diseases - tumors, in which there is immunosuppression, and autoimmune diseases, in which there is over-activation of the immune system.

[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.

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.

[Prospects for the use of polyphenols in multiple sclerosis].

Multiple sclerosis (MS) is a chronic demyelinating autoimmune disease. Therapy for MS does not always slow down the progression of the disease. In many cases, pathogenetic therapy of MS leads to serious side-effects, in particular, to immunosuppression, limiting using of various disease modifying therapy (DMT) in MS.
