Recombinant interleukin-2 (IL-2) therapy for malignancy is associated with a pulmonary vascular leakage syndrome (VLS) similar to that seen in sepsis. We investigated the possibility that the IL-2-induced VLS may be associated with the release of peroxynitrite (ONOO−), and used a model of IL-2-induced VLS in sheep to test the effects of the ONOO− decomposition catalyst WW-85. Eighteen sheep were chronically instrumented and randomly divided into three groups (n = 6 per group): sham: lactated Ringer’s solution, control: IL-2, and treatment: IL-2 and WW-85. Treatment with WW-85 significantly improved lung transvascular fluid flux, decreased lipid peroxidation, limited iNOS as well as PAR intensity, prevented tachycardia, and attenuated the increase in core body temperature resulting from IL-2 treatment. These findings suggest that ONOO− plays a pivotal role in the pathology of IL-2-induced pulmonary VLS, and that WW-85 may become a useful treatment option.
