BACKGROUND: Modulation of serum levels of circulating cytokines and inflammatory responses with a serine protease inhibitor was studied in 34 patients with hepatocellular carcinoma (HCC) after transcatheter arterial embolization (TAE). METHODS: The 34 patients were randomly divided into two groups: 17 patients received 500 mg gabexate mesilate, a serine protease inhibitor, intravenously twice a day for 5 days after TAE, and the remaining 17 patients did not receive the drug. RESULTS: In the patients not given the drug, circulating interleukin-6 (IL-6) markedly increased 1 day after TAE, reached a peak (approximately 8 times the pretreatment value) after 4 days, and remained elevated 7 days after TAE. In comparison, in the patients given the drug, circulating IL-6 was at a significantly lower level at 4 and 7 days after TAE (P < 0.05, respectively). Both groups did not show significant change in circulating interleukin-1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF alpha) during the week after TAE. The drug also showed a tendency to keep patient temperature below 38 degrees C, and the elevation of serum C-reactive protein (CRP) concentration to less than 1 mg/dl after TAE (P < 0.05, respectively). CONCLUSIONS: The serum level of circulating IL-6 can be modulated by serine protease inhibitor, and this may contribute to suppressing inflammatory responses, such as fever and acute-phase protein synthesis, in the liver after TAE.
