Study Objective: To evaluate the tolerance and safety of oral dextran sulfate (UAOO1), a potent in-vitro inhibitor of human immunodeficiency virus (HIV) in patients with the acquired immunodeficiency syndrome (AIDS) and AIDS-related complex.
Design: Unblinded, dose-escalation 8-week trial.
Setting: An AIDS outpatient clinic of a university-affiliated municipal hospital.
Patients: Thirty-four patients with stage III or IV HIV infection were enrolled. Five patients in six different dosage cohorts completed the study. The population was predominantly homosexual men with persistent generalized lymphadenopathy (stage III).
Interventions: Oral dextran sulfate was given three times daily in total daily doses of 900 to 5400 mg for 8 weeks. Patients were monitored for tolerance and toxicity. Immunologic and virologic values were also followed.
Measurements and Main Results: Oral dextran sulfate was given without significant side effects. The commonest minor subjective complications were mental hyperexcitability and gastrointestinal complaints. The most frequent laboratory abnormalities were leukopenia and hepatic transaminase elevations. Eleven patients required dose reductions, and therapy was stopped in 4 because of toxicities. The CD4 lymphocyte numbers did not change appreciably. No decline in beta-2 microglobulin levels occurred. The HIV antigen levels were unchanged from baseline. No assay for dextran sulfate plasma levels has yet proven successful.
Conclusions: Oral dextran sulfate appears to be well tolerated. No evidence of systemic absorption of the parent compound is available. However, in view of the promising invitro effects and acceptable toxicity, oral dextran sulfate as a potential antiretroviral agent continues to be studied.
