摘要
HIV-associated neurocognitive disorders (HAND), characterized by cognitive, motor, and behavioral abnormalities, are common among people living with HIV and AIDS. In combined antiretroviral therapy era in Western countries, nearly 40% of HIV-infected patients continue to suffer from HAND, mainly with mild or asymptomatic cognitive impairment. However, the prevalence and the clinical features of HAND in China are still not well known. In this study, a multi-center cross-sectional study was performed to determine the prevalence and clinical features of HAND in 134 HIV-1 infected patients in China. The International HIV Dementia Scale and a neuropsychological test battery were administered for screening and diagnosis HAND. Subjective complaints, CD4 count and viral loads in both blood plasma and cerebrospinal fluid were correlated with diagnosis of HAND. The results showed that the prevalence of HAND was approximately 37% in these patients. CD4 counts at time of sampling were significant lower in the HAND group than in the non-HAND group. But the distribution of the HAND severity did not differ by CD4 count or viral load. The presence of HAND was associated with cognitive and behavior disorder complaints (4.9- and 4.1-fold higher than those without HAND, respectively). The present data suggest that CD4 count and viral load cannot predict the severity of HAND, although the prevalence of HAND is similar to previous report in these patients. Cognitive and behavioral disorder is major complaint rather than cognitive and motor impairment. A larger prospective study is needed to obtain better estimates of HAND in China.
