  • Title: [Effects of aprotinin on TNF-alpha levels after cardiopulmonary bypass].
    Author: Liu LM, Hu JG, Xu M.
    Journal: Hunan Yi Ke Da Xue Xue Bao; 2000 Apr 28; 25(2):166-8. PubMed ID: 12212211.
    Abstract:
    OBJECTIVE: This study evaluates the anti-inflammatory activity of full-dose and pump-prime-only(low-dose) aprotinin by means of comparing tumor necrosis factor alpha(TNF-alpha) levels of both groups after CPB. METHODS: Twenty-nine adults with rheumatic heart disease were randomized into three groups: (1) full-dose aprotinin-treated group(Group A, n = 10); (2) pump-prime-only aprotinin-treated group(Group B, n = 10), and (3) control group(Group C, n = 9). Plasma concentrations of TNF-alpha were measured by enzyme-linked immunosorbent assay technique at baseline(before operation), and at 2, 24 hours after CPB termination. RESULTS: A significant(P < 0.05) increase of TNF-alpha occurred in all three groups at 2 and 24 hours after CPB termination when compared with the same group at baseline. In Group A, TNF-alpha level was significantly lower than that in group C(P < 0.05) at 24 hours after CPB, but not in group B(P > 0.05). CONCLUSIONS: Both CPB and operative stimulus induce the increase of cytokine TNF-alpha after CPB. Full-dose aprotinin has the anti-inflammatory effect by means of reducing TNF-alpha level after CPB. Low-dose aprotinin dose not reduce TNF-alpha level. So it no significant anti-inflammatory effect.
