CLINICAL AND PATHOLOGICAL MANIFESTATIONS OF BRAIN DAMAGE IN HIV INFECTION

A feature of the HIV epidemic is currently a large number of comorbid and severe forms of the disease, with frequent involvement in the pathological process of the brain. Methods of in vivo verification of brain damage in clinical practice is sufficient, but in some cases they are limited by financial availability and time factor. Correct and timely deciphering of the nature of brain damage is necessary for the choice of treatment tactics, and as a consequence, reducing mortality. Objective: to study the epidemiology, clinic and pathomorphology of brain damage in HIV infection in conditions of urgent and planned admission of patients to a specialized hospital. Materials and methods . Clinical and pathomorphological studies of HIV-infected patients (n=85) receiving specialized medical care were carried out. The final diagnosis was made taking into account clinical, laboratory and morphological data on the classification of ICD-10 in accordance with the domestic requirements of the formulation of comorbid diagnosis. Conclusion . Brain lesions are clinically and morphologically detected in most HIV-infected patients. Opportunistic and secondary diseases with brain damage have their clinical picture, but it is not specific. From the timely decoding of the nature of brain damage depends on the choice of treatment tactics and, as a consequence, reducing the risk of death. Therefore for verification of the etiological agent, you need to conduct a comprehensive examination: clinical (neurological, psychological distress) and laboratory (cellular composition of CSF protein level and glucose) and bacteriological (seeding of CSF on the flora, on Wednesday Saburo to identify mushrooms on medium Bactec and Lowenstein-Jensen medium for detection of M.tuberculesis); immunological (number of CD4-lymphocytes, at.gondii IgM, at.gondii IgG antibodies), molecular genetic (HIV RNA; DNA HSV1, 2; VZV DNA; DNA EBV; CMV DNA; DNA ВГЧ6; T.gondii DNA; DNA of M.tuberculesis; DNA Cr.neoformans; JC virus DNA) and radiological (MRI brain) research methods. The structure of brain damage in deceased patients was dominated by toxoplasmosis in 28,8% of cases; neuroinfection of unspecified etiology in 28,8% and herpesvirus lesion in 11,9%. Rarely met: tuberculosis 8,47%; candidiasis 8,47%; PML 3,39%; cryptococcosis 3,39%; b-cell lymphoma with brain metastases 3,39%.
