AB OBJECTIVE: We have evaluated whether cytokine productions were improved
after initiation of zidovudine (ZDV) or dideoxyinosine(ddI) therapy and
correlated with clinical outcome. PATIENTS: A total of 72 HIV-1 positive
hemophiliacs (25 patients presented with CDC stage A1, 30 with stage A2
and 17 with C3, AIDS) were enrolled. METHODS: Cytokine productions were
tested before and after initiation of the therapy at 6 months intervals
for 1 year. After 100 microliters of whole blood was cultured for 24
hours with lipopolysaccharide, IL-1 alpha and TNF-alpha levels in the
supernatants were quantitated by ELISA methods. CD4+ cell counts and p24
antigen were analysed simultaneously. RESULTS: Significant depressions
of IL-1 alpha and TNF-alpha production were observed on progression of
HIV-1 disease. Restored or deteriorated patients groups were appeared
after starting the therapy. In asymptomatic patients (A1 and A2),
subsequent restoration was associated with less decline of CD4+ cell
counts. In AIDS patients (C3), the restoration reflected improved or
stable clinical status, however, CD4+ cell counts were not associated
with clinical outcome. Only 8 out of the 72 patients had detectable
levels of serum p24 antigen before treatment and decline did not predict
clinical outcome. CONCLUSION: Restoration of cytokine production in
HIV-1 infected hemophiliacs receiving ZDV or ddI therapy reflected good
response to treatment and slowing of disease progression. Our study
suggested the analyses of cytokine productions were new useful markers
of HIV infection.
