We analyzed the relationship between nafamostat mesilate (NM) level and activated coagulation time (ACT) as measured using an Actalyke MINI system vs. an ACTester system in patients with fulminant hepatitis undergoing continuous hemodiafiltration. The hemofilter was made with a polyacrylonitrile membrane, and NM was used as the anticoagulant. Significant correlation was found between the NM dose and the prehemofilter ACT measured by the Actalyke MINI system ( r = 0.561, P = 0.0352, n = 14). However, no significant correlation was found between the NM dose and the prehemofilter ACT measured by the ACTester. Neither was a significant correlation found between the prehemofilter NM level and the prehemofilter ACT measured by either system. No significant correlation was found between the NM dose and the posthemofilter ACT measured by either system. The ACTester uses a test tube containing celite and a small amount of kaolin as a coagulation activator. The results of the present study suggest that the ACTester can adsorb NM and that this feature can affect ACT measurement. Considering this influence and the need to minimize the dose of NM in patients with fulminant hepatitis to avoid hemorrhagic tendencies, it is advisable to use the Actalyke MINI system.
