Relationship of Human Immunodeficiency Virus Viral Load in Cerebrospinal Fluid and Plasma in Patients Co-infected With Cryptococcal Meningitis
Research output: Contribution to journal › Article › Research › peer-review
We measured human immunodeficiency virus (HIV) ribonucleic acid (RNA) in paired cerebrospinal fluid (CSF) and plasma samples in a prospective study of 91 HIV-infected, antiretroviral therapy-naive patients with cryptococcal meningitis. Cerebrospinal fluid HIV RNA was lower than in plasma (median 4.7 vs 5.2 log10 copies/mL, P < .0001) and positively correlated with plasma HIV RNA, peripheral CD4+ T-cell percentage, and CSF CXCL10. Plasma/CSF ratio of HIV RNA ranged widely from 0.2 to 265.5 with a median of 2.6. Cerebrospinal fluid quantitative cryptococcal culture positively correlated with CSF CCL2 and CCL3. CSF-plasma viral discordance was not associated with cryptococcal-associated immune reconstitution inflammatory syndrome.
