Human immunodeficiency virus-associated meningitis. Clinical course and correlations.
Fourteen patients infected with human immunodeficiency virus (HIV) had a lymphocytic pleocytosis unexplained by secondary pathogens or neoplasms. Three men had prior diagnoses of Kaposi's sarcoma; none had acquired immune deficiency syndrome-defining opportunistic infections. Two patterns of illness were observed. Seven men had an acute, self-limited illness that was often accompanied by meningeal findings. The other seven had chronic headaches without signs of meningeal irritation and had less marked abnormalities of cerebrospinal fluid (CSF) cell count and protein. Encephalopathy was a finding in only one of 14 patients. In four of five CSF specimens studied, HIV was recovered. HIV has been associated with acute meningitis at the time of seroconversion and can apparently also cause sporadic episodes of acute or chronic meningitis in patients with prior infection and relatively preserved immune function. Both the clinical presentation with predominant headache rather than encephalopathy and the presence of CSF inflammation differentiate this syndrome from other HIV-related neurologic complications.
