Patients receive interferon alpha-2b subcutaneously 3 times weekly for 6 months. If no response is seen after 18 weeks of therapy or if an initial response is followed by relapse while on therapy, dose is increased. Patients who require a dose escalation should continue on IFN alfa-2b for an additional 6 months. All patients will also receive available nucleoside analog therapy ( zidovudine, didanosine, zalcitabine ) at currently accepted doses as clinically appropriate.
