Modern aspects of central nervous system damage in patients with HIV infection (literature review)

Abstract

The literature review highlights modern ideas about the pathogenesis, pathomorphology, and clinical manifestations of central nervous system damage in patients with HIV infection, and also touches on the problems of diagnosis and treatment of these opportunistic infections. Particular attention should be paid to patients with severe immunodeficiency (CD4+T-lymphocyte count < 200 cl/ml) due to the high risk of secondary diseases of the central nervous system. Along with the etiological verification of opportunistic diseases of the central nervous system, magnetic resonance imaging of the brain is important at the initial stage of diagnosis, with the help of which it is possible to identify changes in the brain substance characteristic of certain pathogens. In addition to the basic etiotropic therapy of opportunistic infections in HIV patients, effective antiretroviral therapy and its index of penetration into the central nervous system play a crucial role.
