Abstract

Background: Interest in the study of combined pathology in recent times is explained by the accumulation
of new facts, the emergence of new information on interorgan, intertissue and intercellular levels of
interaction in the system of the whole organism. In this regard, the issue of the relationship between diseases
of internal organs and organs of the oral cavity is relevant
Тhe aim of the study was to examine the condition of the oral cavity and the level of proinflammatory IL-2
and ɤ-INF in the oral fluid of patients with viral hepatitis C before and after complex treatment.
Material and methods: The study involved 96 patients with HCV with lesions of the oral mucosa and
periodontium, as well as 100 patients of the control group without HCV. All patients had their dental status
and index assessment of the periodontal tissue condition studied. Cytokines IL-2, ɤ-INF were determined in
the oral fluid. All indicators were studied before and after complex treatment and compared with each other.
Results: Objective examination of the oral cavity of patients with HCV revealed the presence of a generalized
inflammatory process in the alveolar part of the gums, as well as damage to the OM (p<0.001). In HCV, proinflammatory IL-2 significantly increases, and ɤ-INF increases, but not statistically significantly (p>0.113).
After complex treatment, statistically significant improvements are observed in the OM and alveolar part of
the gum (p<0.001). Pro-inflammatory IL-2 decreased (p<0.001), and ɤ-INF decreased, but statistical
significance is not observed (p>0.121).
Conclusion: Thus, a comparative study of lesions of the OM and alveolar part of the gingiva before and after
the complex treatment for HCV revealed that the main pathognomonic symptoms reliably undergo dynamics
towards improvement and are detected with a lower frequency. When comparing the results of interleukin
levels in the OF before and after HCV treatment, a decrease in the level of proinflammatory IL-2 is noted,
the level of ɤ-INF also decreases (but the difference in the data is insignificant). Further studies are needed to
better understand the level of IL-c in patients with HCV and its relationship with damage to the oral mucosa
and periodontium.
