AB RATIONALE AND OBJECTIVE: Interferon alpha (IFN-alpha) has
anti-retroviral activity and is a possible HIV infection-limiting
factor. The aim of this work is to prevent or delay disease progression
in asymptomatic Human Immunodeficiency Virus (HIV) carriers. DESIGN AND
INTERVENTIONS: Recombinant IFN alpha-2b (3 x 10(6) IU 3 times weekly)
was compared to no treatment (control) in a randomized trial. Endpoints
were: (i) appearance of any CDC group IV symptoms and (ii) disease
progression (which excluded shifts to group IVC2 or reversible IVA, or
IVB). The trial lasted from October 1987 to February 1992. SETTING: The
trial was performed at the Santiago de las Vegas sanatorium, a
specialized institution for the care of HIV-infected and AIDS patients.
POPULATION: Subjects were anti-HIV-1 seropositive, Western
blot-confirmed, asymptomatic (CDC group II), or with generalized
lymphadenopathies (CDC group III). The groups had 79 (control) and 71
(IFN) patients. MAIN RESULTS: Long-term IFN-alpha treatments
significantly reduced the proportion of patients who shifted to any
group IV (control: 46/79; IFN: 14/71; p < 0.001) or developed AIDS
(control: 27/79; IFN: 12/71; p < 0.05). IFN also delayed progression to
AIDS (95% confidence interval for 0.5 probability of progression) from
67-83 to 116-180 months after infection. The IFN group had significantly
less opportunistic infections and non-infectious complications. CD4 cell
count and hemoglobin decreased in the control but not in the IFN group.
Fewer IFN-treated patients developed positive serum HIV antigen
detection. CONCLUSION: IFN alpha treatment during the early stages of
infection seems to be beneficial to the patients.
