CLINICAL FEATURES OF THE HIV INFECTION COURSE AND THE DEPENDENCE OF CHANGES IN LABORATORY PARAMETERS ON THE CLINICAL STAGE AND ON THE CD4 LYMPHOCYTES LEVEL

Abstract

The aim: Is to determine the features of the HIV infection and changes in indicators of endogenous intoxication and immunoreactivity depending on the clinical stage and the level of CD4 lymphocytes. Materials and methods: 72 HIV-patients were examined. Comparison group included 40 healthy blood donors. Clinical and laboratory examination was performed. Indicators of endogenous intoxication, nonspecific reactivity and inflammatory activity were calculated. Results:Main opportunistic infections were: oropharyngeal candidiasis; tuberculosis of different localization, more often pulmonary tuberculosis; and brain toxoplasmosis (p<0,05). Indices of endogenous intoxication and immunoreactivity are important objective criteria for diagnosis. In groups where the distribution of patients depended on the level of CD4 cells – HIV (CD4≥500) and HIV (CD4≤499-200), index changes were more pronounced than in the HIV I and HIV III groups. The most significant changes in indexes were in the HIV IV clinical group and the HIV (CD4≤199) group: endogenous intoxication indexes were increased by 1,2-7,5 and 1,9-13,7 times in both groups respectively. Non-specific reactivity indexes were decreased by 1,2-1,6 and 1,3-1,6 times, respectively; nuclear index (NI) in groups was 3 and 3,4 times higher (p<0,05–0,001). Changes in indexes of inflammatory activity were observed (p<0,05-0,001). Conclusions: Main diagnosed opportunistic infections were: oropharyngeal candidiasis; tuberculosis of different localization; and brain toxoplasmosis (p<0,05). Indices of endogenous intoxication and immunoreactivity are important objective criteria for diagnosis. The most significant changes in indexes were in the HIV IV clinical group and the HIV (CD4≤199) group (p<0,05-0,001).
