    Abstract:
    BACKGROUND: While highly active antiretroviral therapy (HAART) allows for the considerable decline in the incidence of HIV-related opportunistic infections and tumors, its effect on treating HIV infection of the brain, such as HIV-associated dementias (HADs), remains unclear. METHODS: A cross-sectional study of consecutive series of 96 patients from the Serbian HIV/AIDS cohort, treated with HAART in our HIV unit was performed to evaluate the incidence of and risk factors for cognitive/motor complex during HAART. CD4+T cell counts and pVL values at the time of neurological evaluation were parameters of the response to HAART. The mini-mental test and neurologic examination were performed at one point of time during treatment to reveal cognitive and/or motor disorders. RESULTS: After mean HAART duration of 47 months, unimpaired cognition, minor cognitive impairment, and HIV-associated dementia were recorded in 56 (58.3%), 27 (28.1%), and 13 (13.5%), respectively. Motor abnormalities had 39 (40.6%) patients. Of these, 21, 12, and 6 patients belong to the subgroups with normal cognition, minor cognitive impairment and HAD patients, respectively. Factors predictive for HAD were age over 40 (OR 3.7, 95% CI 1.07-13.28, P=0.039), and AIDS diagnosis prior to HAART initiation (OR 14.19, 95% CI 1.76-114.16, P=0.013). Conversely, factors shown to be protective against HAD were the usage of AZT and NNRTIs, as components of HAART regimens (OR 0.18, 95% CI 0.046-0.76, P=0.019, and OR 0.14, 95% CI 0.034-0.6, P=0.008). CONCLUSION: Cognitive/motor complex has still remained a significant neuropathology among late presenters and elder HIV/AIDS patients. Certain HAART regimens containing AZT, and/or NNRTIs, could be protective for these patients.
