Pediatric neuro-AIDS may be the first clinical manifestation of HIV infection in children born to HIV-infected mothers. As part of the neurodevelopmental examination of children, the Clinical Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) was investigated as a tool for pediatricians to use to monitor the development of children at risk for HIV infection. The CAT/CLAMS was found to detect neurodevelopmental differences between HIV-infected and uninfected children at 12 and 18 months of age. Good correlations were found between the CAT/CLAMS and concurrently administered Bayley Scales of Infant Development. These findings suggest that the CAT/CLAMS should be considered as a part of the neurodevelopmental examination of children at risk for pediatric neuro-AIDS.
An 8-year, 2-month-old African-American boy was infected with HIV through vertical transmission. Regular monitoring of the patient's neurodevelopmental status has been conducted as part of his participation in longitudinal research protocols. For the first 51/2 years of life, his neurodevelopmental status was normal, with cognitive functioning as measured by standardized psychometric tools solidly in the average range. Speech and language skills were age-appropriate. Tests of gross and fine motor functioning as well as evaluation of overall neurodevelopmental status suggested normal development. Magnetic resonance imaging (MRI) of the brain was consistently normal. His family reported that adaptive functioning, peer and family relationships, and behavior were all within normal limits. School reports indicated consistently that the patient was performing at age and grade level, with respect to both academic achievement and behavior. Initial concerns regarding the patient's development were expressed by both his family and school at age 6 years, 6 months. These concerns included difficulty with classroom work, decreased attention, word-finding problems, fatigue, staring spells, and loss of strength. His family and school reported a marked loss of skills acquired previously. Results of formal psychological and speech and language evaluation reflected statistically significant drops in test scores from baseline, with both delayed and atypical skills evident. The patient's condition worsened rapidly. Within a few months, he was no longer able to use sentences to communicate. Cognitive testing was attempted, but he was unable to participate because of significant fatigue, limited attention, and inability to communicate verbally. His family described periods of disorientation and confusion, lethargy, and disinterest in age-appropriate activities. He became agitated and overstimulated easily both in small group settings and in crowds. He demonstrated both fine and gross motor impairments. When frustrated, he displayed infantile and autistic-like behavior. MRI with contrast showed diffuse atrophy as well as mild prominence of the ventricles and sulcii compared with baseline assessment. In addition to fatigue and neurologic symptoms, wasting syndrome was diagnosed, with loss of percentiles in both weight and height by age 71/2 years. Low-grade elevation of liver function tests and amylase was noted. Blood cultures for mycobacteria were negative, as were serologic tests for hepatitis. (ABSTRACT TRUN
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
