Longitudinal Study of Cognitive Function in People with HIV and Toxoplasmic Encephalitis or Latent toxoplasma Infection.
Background: Neurocognitive impairment (NCI) may occur during and persist even after recovery from HIV-related CNS co-infections such as toxoplasmic encephalitis (TE). The long-term cognitive effects of TE and latent toxoplomasmic infections (LTI) among persons with HIV (PWH) are unknown. We measured longitudinal effects on NC functioning in PWH with TE compared to LTI or no toxoplasmal infection.
Methods: PWH (n = 345) followed in two longitudinal cohort studies underwent comprehensive neurocognitive assessments and an anti-Toxoplamic IgG assay. Participants were classified into one of three groups: TE+ (n = 39), LTI+ (n = 34), LTI- (n = 272). The primary outcome was change in neurocognitive function between baseline and 7-year visit.
Results: The mean age was 48 ± 11 years, mean educational level 13 ± 3 years, and 13% were female. TE+ patients were less likely to have undetectable viral loads (≤50 copies/mL) and had lower absolute CD4 counts. The TE+ group had the highest prevalence of NCI globally and in domains of verbal, executive function, learning, recall, working memory, processing speed and motor at baseline and at 7-year follow-up. Changes in longitudinal NC function over 7 years were small and did not differ significantly among all groups, except that speed of information processing improved more in TE+ compared with LTI- participants.
Conclusions: PWH with a history of TE had cognitive impairment over a broad range of severity at both baseline and last follow-up. Changes in cognition from baseline to last examination in all groups were minimal and did not differ significantly among the groups with the exception of speed of information processing.
期刊介绍:
Publishing the very latest ground breaking research on HIV and AIDS. Read by all the top clinicians and researchers, AIDS has the highest impact of all AIDS-related journals. With 18 issues per year, AIDS guarantees the authoritative presentation of significant advances. The Editors, themselves noted international experts who know the demands of your work, are committed to making AIDS the most distinguished and innovative journal in the field. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
