Abstract:
Objective To discuss the changes and significance of interleukin-17 (IL-17) in perioperative period of congenital heart disease patients with pulmonary hypertension. Methods A total of forty patients with congenital heart disease underwent cardiopulmonary bypass (CPB) were included in this study. According to the pulmonary artery systolic pressure (PASP), patients were divided into non-pulmonary hypertension group (group Ⅰ, PASP < 30 mmHg) and pulmonary hypertension group (groupⅡ, PASP≥30 mmHg). Blood samples were taken before anesthesia (T1), start CPB (T2), 30 min after CPB (T3), 6 h (T4), 24 h (T5) and 7 d (T6) after operation. The concentration of IL-17 was detected by ELISA. Arterial oxygen partial pressure [p(O2)] and arterial carbon dioxide partial pressure [p(CO2)] during the first five time points were recorded. Oxygen index (OI) and alveolar arterial oxygen tension difference (AaDO2) were calculated. Results The plasma IL-17 levels in perioperative period were significantly higher in group Ⅱ than those of group Ⅰ (P < 0.05). The highest concentration of IL-17 emerged at T3, then decreased gradually in both groups. At this time point, the OI decreased, and AaDO2 increased significantly in both groups. Compared with groupⅠ, the OI decreased, while AaDO2 increased at T5 in groupⅡ(P<0.05). Conclusion The high level of IL-17 promotes the formation of pulmonary hypertension in congenital heart disease and leads to the lung injury during CPB, which can be used as a clinical monitoring indicator of evaluating severity.
