| Research Abstract |
Background: The role of purinergic receptors in pathogenesis of postoperative critical illness following major surgery was prospectively investigated. Methods: Expression levels of P2X7, A2A, T-bet, and GATA-3 mRNA in peripheral blood mononuclear cells were assayed by reverse transcription-polymerase chain reaction perioperatively in 49 consecutive patients who underwent major hepatobiliary pancreatic surgery. Results: P2X7 mRNA expression and P2X7/A2A ratio were significantly lower in unfavorable group (p < 0.05) in preoperative or early postoperative period. Postoperative T-bet/GATA-3 ratio was significantly lower in unfavorable group (p < 0.05). T-bet/GATA-3 ratio correlated significantly with P2X7 mRNA expression and P2X7/A2A ratio on POD 0 and 1 (p < 0.01). P2X7 mRNA expression on POD 0 negatively correlated with severity of complications (p < 0.05). Conclusions: These results suggest that P2X7 and A2A may play a pivotal role in pathogenesis of postoperative critical illness.
