title: Diagnostic value of multimodal evoked potentials in HIV-1 infected children.
abstract: Evoked potentials (EP) help guide the diagnosis of central nervous system involvement in demyelinating pathologies regarding both children and adults, and in human immunodeficiency virus-1 (HIV-1) correlated pathologies only in regard to adult patients. EP have been shown to be useful in highlighting early signs of the disease. We therefore studied EP in HIV-1 infected children with the aim of verifying the association of results with disease progression, clinical signs and electroencephalogram, and individualizing the most reliable test. Thirty-six patients (20 male and 16 female subjects, age range: 10 months to 12 years) belonging to a group of 45 symptomatic subjects seen at the Pediatric Department were included into the study from November 1991 to December 1994. Ten presented with neurological signs as of disease onset, eight others developed encephalopathy during the follow-up. One hundred seventeen EP, i.e., 27 pattern visual, 64 flash visual and 26 brain stem auditory EP, were recorded. Univariate statistical analysis using the Wilcoxon-Mann-Whitney U test and Student's t test was done. As a whole, we found 22.5% of abnormal EP in subjects without neurological signs and 28.3% in subjects with neurological signs. Results that were obtained suggested a close relationship between both the pattern of visual and brain stem auditory EP exams and disease progression.
