    Fusobacterium nucleatum: from a classic periodontal pathogen to a complete participant of carcinogenesis

    Fusobacterium nucleatum is a component of the oral microflora, and in clinical practice it is associated primarily with periodontal diseases. Since 2011, the scientific community has confirmed the association of F. nucleatum with colorectal cancer (CRC) by seeding it from tumor tissue samples. Research has led to the discovery of mechanisms by which this bacterium may contribute to the development, metastasis of CRC and chemoresistance. With the help of its adhesion proteins (FadA and Fap2) F. nucleatum specifically attaches to colorectal carcinoma cells. Following invasion, F. nucleatum induces inflammation, activates Ξ²-catenin signaling, and creates a favorable microenvironment for tumor growth and development. Recently, the role of F. nucleatum in other types of oncological pathology, such as oral cavity cancer, head and neck cancer, gastric cancer, esophageal cancer, pancreatic cancer, cervical cancer and breast cancer, has been confirmed. Understanding the mechanisms of association of F. nucleatum with oncological diseases will help to find new approaches in the treatment, prevention and diagnosis of cancer. Thus, further studies of the correlation between F. nucleatum and carcinogenesis are needed, using a multidisciplinary approach and physicians from other specialties

    Background. Vaccination against pneumococcal infection is one of the priorities in improving the quality of treatment and prevention measures in adults with various pathologies. The effectiveness of vaccination is directly related to the individuals ability to form an adequate specific immunity. Aims the aim of the study was to assess the level of post-vaccination antibodies to capsular polysaccharides of S. pneumoniae in adult patients with bronchial asthma (BA) or chronic obstructive pulmonary disease (COPD) after administration of 13-valent conjugated pneumococcal vaccine (PCV13). Materials and methods. The ELISA method was used to determine the level of IgG antibodies to 12 capsular polysaccharides serotypes 1, 3, 4, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F of S. pneumoniae that are part of PCV13, and 2 serotypes 9N, 15B that are not part of the vaccines using research test systems developed on the basis of the I.I. Mechnikov Research Institute of Vaccines and Sera. Groups of adult patients 32 patients with BA and 33 with COPD who received basic treatment according to accepted international standards. The comparison group consists of 20 healthy patients who do not have comorbidities. In patients, vaccination was performed outside the acute period of the disease using PCV13. Results. Vaccination of PCV13 patients with BA and COPD does not lead to the development of exacerbations of the underlying disease, while unusual symptoms in the post-vaccination period, provided for by the drugs instructions, can rarely develop. A comparative analysis of changes in IgG antibodies conducted after 6 weeks relative to the initial level of IgG antibodies to S. pneumoniae capsular polysaccharides in adult patients and healthy vaccinated PCV13 showed the same increase in specific antibodies to 12 serotypes of pneumococcus. The difference was found only in relation to IgG antibodies to a mixture of polysaccharides included in the PCV13 vaccine, which were registered higher in patients with BA and COPD in the post-vaccination period (p 0.001) than in healthy patients. Conclusions. PCV13 vaccination of patients with BA and COPD is safe and is accompanied by the synthesis of IgG antibodies to capsular polysaccharides serotypes of S. pneumoniae similarly to the healthy group.ОбоснованиС.
