Ulinastatin's Anti-inflammatory Reaction in Cardiac Surgery (ulistin)
|ClinicalTrials.gov Identifier: NCT01518569|
Recruitment Status : Completed
First Posted : January 26, 2012
Last Update Posted : January 26, 2012
The purpose of the present study is to determine whether ulinastatin, urinary anti-trypsin inhibitor, attenuates cardiopulmonary bypass (CPB)-activated systemic inflammatory response in cardiac surgery with CPB.
Serial measurements and analysis of several inflammatory cytokines (bactericidal permeability increasing protein, interleukin-6, tumor necrosis factor-α)as well as markers of cardiac injury, renal impairment and oxygenation profile will be performed to determine ulinastatin's efficacy.

Applying aortic cross-clamp (ACC) and cardiopulmonary bypass (CPB) for cardiac surgery produces variable systemic inflammatory reactions. As a common complication of those reactions, pulmonary dysfunction, which usually indicated by postoperative hypoxemia, is frequently associated with cardiac surgery employing CPB and has been used as a major predictor of morbidity and mortality.
Circulating humoral and cellular factors are involved in the development of the systemic inflammatory reactions including organ dysfunction. So far, many studies analyzed the concentration of inflammatory marker (cytokine) to determine the degree of systemic inflammatory responses in various conditions.
Ulinastatin has anti-inflammatory activity and suppresses the infiltration of neutrophils. Previous studies suggested ulinastatin's cytoprotective effect against ischemia-reperfusion injury in major organs and its inhibition of inflammatory marker production.
The purpose of the present study is to determine ulinastatin's possible protective efficacy of in attenuating CPB-activated systemic inflammatory response regarding postoperative cardiac, renal and pulmonary dysfunction in cardiac surgery with CPB. Serial measurements and analysis of several inflammatory cytokines, such as bactericidal permeability increasing protein (BPI), interleukin (IL)-6, tumor necrosis factor (TNF)-α, as well as markers of cardiac injury, renal impairment and oxygenation profile, such as creatine kinase-MB (CK-MB), troponin I (TnI), C-reactive protein (CRP), arterial O2 tension /inspired O2 fraction (PaO2/FiO2 ratio), will be performed to this purpose.
