Abstract/OtherAbstract:
Single-lung transplantation after 3 h of hypothermic storage produces bilateral lung injury [pulmonary reimplantation response (PRR)]. We hypothesized that glutathione (GSH) hypothermic storage would protect both lungs from PRR for extended preservation times and that differences in injury and protection would be realized between the graft and the nontransplanted lung. Mongrel dogs underwent left single-lung autotransplantation after preservation for 5-6 h in Euro-Collins (EC) solution, EC plus exogenous GSH (EC+GSH), or Viaspan (VIA) at 4 degrees C. Lung injury was measured in both lungs after 1 h of reperfusion. EC dogs demonstrated significant increases in lung edema, lipid peroxidation, and alveolar neutrophil recruitment in the lung graft and to a less extent in the nontransplanted right lung compared with control dogs (P < 0.05). Edema, lipid peroxidation, and alveolar neutrophils were significantly reduced in both lungs from EC+GSH and VIA dogs compared with lungs from EC dogs (P < 0.05). An increase in large-pore permeability was measured in the lung graft from EC dogs compared with all other lungs. Bronchoalveolar lavage fluid lactate dehydrogenase and total protein concentrations were elevated in both lungs from all three groups of tranplanted dogs compared with those of control dogs (P < 0.05). These data suggest that GSH-containing solutions attenuate the PRR after 6 h of ischemic hypothermic storage but that the protection is incomplete. Mechanisms of injury affecting the lung graft during the PRR appear to differ from those affecting the nontransplanted lung.
