Ibuprofen in experimental group B streptococcal shock.
A rabbit model was used to characterize the effects of high (Group II, 100 mg/kg) and low (Group III, 10 mg/kg) dose ibuprofen in modulating the hemodynamic and hematologic manifestations of group B streptococcal shock. Short-term survival was significantly increased with ibuprofen pretreatment. Ibuprofen failed to prevent GBS-induced shock, although shock was favorably modified in a dose dependent manner. Likewise, GBS-induced increases in 6KPGF1a and TxB2 were not prevented but were modified in Group II at 120 min. However, neutropenia, thrombocytopenia, and acidosis were not prevented by pretreatment with ibuprofen and may have been exacerbated. Thus, ibuprofen modifies but does not prevent GBS-induced hemodynamic and hematologic manifestation.
