Safety and Tolerability of Nafamostat Mesilate and Heparin as Anticoagulants in Leukocytapheresis for Ulcerative Colitis: Post Hoc Analysis of a Large-Scale, Prospective, Observational Study.
Nafamostat mesilate is the first anticoagulant of choice for leukocytapheresis (LCAP) with a Cellsorba E column for treating ulcerative colitis (UC). However, because of complications, mainly due to allergy to nafamostat mesilate, heparin may be used as a substitute. To evaluate the safety and tolerability of nafamostat mesilate and heparin as anticoagulants in LCAP for UC, we conducted post hoc analysis of data from a large-scale, prospective, observational study of LCAP, which was conducted at 116 medical facilities in Japan between May 2010 and December 2012. ⋯ Adverse reactions of hemorrhage or blood pressure decreases associated with heparin use were not observed. There were no significant differences in rates of clinical remission (69.1% vs. 68.1%) and mucosal healing (62.9% vs. 63.6%) between the nafamostat mesilate and heparin groups. Thus, the safety and tolerability were comparable in the nafamostat mesilate and heparin groups, indicating that both nafamostat mesilate and heparin can be well tolerated as anticoagulants in LCAP for UC.
