orthotopic Liver Transplantation
consecutive inclusion of all recipients

Detailed Description:
The investigators examined the frequency of anti-PF4/heparin antibodies (IgG/M/A; EIA) and their functional activity (HIPA) in 38 whole organ deceased donor liver transplant recipients. Additionally, demographic, clinical, donor- and recipient-specific parameters and laboratory findings (ALAT, ASAT, cholinesterase) were investigated.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
