Проявления ВИЧ-инфекции в полости рта у пациентов в зависимости от содержания CD4+ Т-лимфоцитов в крови

Abstract

Objective - analysis and generalization of the available data on the manifestations of human immunodeficiency virus in the oral cavity depending on the number of CD4+ T-lymphocytes in the blood. Materials and methods. A search of clinical studies, systematic reviews, and online meta-analyses was conducted from 2004-2023 in the PubMed, Elsiever, Scopus, Cochrane, and Elibrary databases, which described oral manifestations of HIV infection as a function of CD4+ T-lymphocyte count. Results. Pseudomembranous candidiasis, hairy leukoplakia, Kaposi's sarcoma, and non-Hodgkin's lymphoma develop against a background of severe immunodeficiency when the CD4+ T-lymphocyte count is <200 cells/μL blood. Kaposi's sarcoma also develops in people with a high CD8+ T-lymphocyte count (>1000 cells/μL of blood) or with a low CD4+ to CD8+ ratio (CD4+:CD8+ ≤0.5). Non-Hodgkin's lymphoma develops not only with CD4+ T-cells <200/μL, but also with a high number of CD8+ T-cells (≥2000 cells/μL of blood). Specific periodontal disease develops with moderate to severe immunodeficiency (CD4+ T-cells 200-500 cells/μL of blood). Necrotic ulcerative gingivitis is more often seen in severe immunodeficiency (CD4+ T-lymphocytes <200 cells/μL). Conclusion. The development of pseudomembranous candidiasis (p<0,05), "hairy" leukoplakia (p<0,01), Kaposi sarcoma (p<0,0001) statistically significantly correlates with CD4+ T-lymphocyte count <200 cells/μl blood. In addition, the development of Kaposi's sarcoma, in addition to the low number of CD4+ T-cells, is affected by a high number of CD8+ cytotoxic lymphocytes >1000 cells/μL (p=0.0003) and a low CD4+:CD8+ ratio ≤0.5 (p<0.0003), which is statistically significant.
