OBJECTIVES: Is it possible to live without neurocognitive or neurological
symptoms after being infected with HIV for a very long time? These study patients
with decades-long HIV infection in Finland were observed in this follow-up study
during three time periods: 1986-1990, in 1997 and in 2013. SETTING: Patients from
greater Helsinki area were selected from outpatient's unit of infectious
diseases. PARTICIPANTS: The study included 80 HIV patients. Patients with heavy
alcohol consumption, central nervous system disorder or psychiatric disease were
excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: The patients underwent
neurological and neuropsychological examinations, MRI of the brain and laboratory
tests, including blood CD4 cells and plasma HIV-1 RNA. Neuropsychological
examination included several measures: subtests of Wechsler Adult Intelligence
Scale, Wechsler Memory Scale-Revised, list learning, Stroop and Trail-Making-B
test. The Beck Depression Inventory and Fatigue Severity Scale were also carried
out. The obtained data from the three time periods were compared with each other.
RESULTS: Owing to high mortality among the original 80 patients, eventually, 17
participated in all three examinations performed between 1986 and 2013. The time
from the HIV diagnosis was 27 (23-30) years. Blood CD4 cells at the diagnosis
were 610 (29-870) cells/mm(3), and the nadir CD4 168 (4-408) cells/mm(3). The
time on combined antiretroviral treatment was 13 (5-17) years. 9 patients
suffered from fatigue, 5 had polyneuropathy and 3 had lacunar cerebral infarcts.
There was a subtle increase of brain atrophy in 2 patients. Mild depressive
symptoms were common. The neuropsychological follow-up showed typical age-related
cognitive changes. No HIV-associated dementia features were detected.
CONCLUSIONS: Polyneuropathy, fatigue and mild depression were common, but more
severe neurological abnormalities were absent. These long-term surviving
HIV-seropositive patients, while on best-available treatment, showed no evidence
of HIV-associated neurocognitive disorder in neuropsychological and
neuroradiological evaluations.
