To investigate the effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on sepsis, chronically catheterized conscious pigs were challenged withPseudomonas aeruginosa(8 ± 107colony-forming units kg-1h-1) for 84 h (Group A, n = 8). Group B (n = 7) also received rhG-CSF at 5 μg kg-1d-1, the first dose being given 30 min before starting bacterial infusion. Two of the animals in Group A died from pulmonary failure, whereas all those treated with rh-GCSF survived. Fever, severe pulmonary hypertension and systemic hypotension-the latter accompanied at first by a transient hypodynamic, and later a hyperdynamic response-were observed in all of the animals. In Group B, however, the rise in temperature, mean pulmonary arterial pressure (at a later stage of the observation), plasma levels of tumor necrosis factor, and endotoxin were significantly less than in Group A. In the rhG-CSF-treated pigs, an initial leukopenia completely recovered within 24 h (p .05 vs. Group A). These data suggest that rhG-CSF might be beneficial in the treatment of sepsis.
