Ibuprofen attenuates early lung injury in endotoxemic, neutropenic rats.
The objective of our study was to determine the role of ibuprofen in protecting neutropenic rats from cardiopulmonary injury due to endotoxemia. We hypothesized that ibuprofen would offer pulmonary protection by altering cytokine production. Neutropenic rats received E. coli lipopolysaccharide (LPS) alone or ibuprofen and LPS. ⋯ Neutrophil infiltration in the lung was similar in both groups. Ibuprofen attenuated cardiopulmonary dysfunction by decreasing the early cytokine response. The balance of vasodilator to vasoconstrictor production in the lung may favor vasodilation as shown by increased iNOS mRNA and suppression of thromboxane.
