title: Ssytemic effects of intravenous polyriboinosinic-polyribocytidylic acid in man.
abstract: To investigate the systemic, clinical and laboratory effects of iv polyriboinosinic-polyribocytidylic acid (poly I-poly C), 32 doses of poly I-poly C were administered to 22 patients. Doses between 1 and 10 mg/kg induced the formation of serum interferon (IF) and fever. Whereas a direct relationship was seen between the poly I-poly C dose and fever, serum IF levels were not significantly changed by increasing the dose of poly I-poly C over a log range from 1 to 10 mg/kg. Transient abnormalities were noted in liver function tests in 4 of 13 patients who received greater than 6.0 mg/kg. Other laboratory changes were confined to an increase in the absolute granulocyte count that paralleled fever development and abnormalities in coagulation parameters of 1 patient. In vitro lymphocyte DNA synthesis in response to mitogens was transiently impaired at times corresponding to serum IF appearance. These studies have established dose levels of poly I-poly C that can be safely administered to man with minimal toxicity and result in IF induction.
