Task: Intent Identification
Input (English): There is no reliable serum marker available to monitor incipient pancreas or islet-cell rejection. We tested the hypothesis that quantification of donor-specific genomic DNA in serum (from tissue damage) can serve as a marker of rejection.', 'Using a recently developed panel of HLA-specific quantitative PCR assays (Q-PCR), we tested 158 sera from 42 pancreas-kidney transplant recipients. Temporally related biopsies for 65 sera permitted analysis for correlation of donor DNA concentrations with rejection.', 'Donor DNA concentrations were higher in sera from recipients who had experienced allograft rejection (n = 31) than from those who had not (n = 34). Median concentrations, expressed as the genome-equivalent (gEq) number of donor cells per 10(6) host cells, were 2613 and 59 gEq/10(6), respectively (P = 0.03).
