abstract

  • While HLA class II alleles identification by means of complement mediated lymphocytotoxicity (serology) is almost replaced by DNA typing techniques, serology is still widely used for routine class I typing. The aim of this prospective study was to compare PCR-based Amplification Refractory Mutation System with serology in clinical HLA class I alleles assignment in patients receiving marrow transplants and their potential donors. The total discrepancy rate in 114 consecutively typed individuals for HLA-A and HLA-C alleles was only in favor of ARMS-PCR, whereas HLA-B typing was discrepant also in favor of serology. The discrepancies were higher in patients, particularly in those with acute lymphoblastic leukaemia, than in healthy individuals. We conclude, that ARMS-PCR is clearly superior to serology in definition of class I alleles, which might be of clinical importance particularly for bone marrow transplantation.
