Unique Identifier : AIDSLINE ASHM6/95291771 AB OBJECTIVES: To investigate the ability of clinical, laboratory and demographic variables to predict the presence of dementia and neuropsychological impairment in patients with CD4 count < 200. METHODOLOGY: 50 HIV- and 59 HIV+ subjects were assessed neurologically and neuropsychologically, and a subset of subjects underwent lumbar punctures. Logistic regression was used to determine which variables from a set including age, education, IQ, depression, anxiety, CD4 cell counts, haemoglobin, serum and CSF beta 2 microglobulin and neopterin, constitutional symptoms, past opportunistic infections and use of antiretroviral therapy predicted the occurrence of dementia according to the ADC rating scale, and cognitive impairment according to four criteria of neuropsychological abnormality. RESULTS: An increased likelihood of neurological and neuropsychological dysfunction was associated with a history of weight loss six months prior to assessment, diarrhoea at some time in the recent past, and a high level of serum neopterin at the time of assessment. A decreased likelihood of impairment was associated with a higher estimated IQ, more years of education, and use of zidovudine, but not ddI, for longer than two months at the time of assessment. CONCLUSION: The results support a model of increased cytokine production causing systemic and cerebral damage, and provide a simple clinical method for screening for the presence of ADC.
