BACKGROUND: New methods of solid-phase assays, such as Luminex assay, with high sensitivity in detecting anti-human leukocyte antigen (HLA) antibodies (Abs), have increased the proportion of sensitized candidates waiting for lung transplantation (LTx). However, how to apply these results clinically during graft allocation is debated: strict exclusion of candidates with Luminex-positive results can lead to lost opportunities for Tx. We retrospectively analyzed the clinical impact of pre-LTx Luminex-detected Abs on post-LTx outcomes for patients who underwent LTx before the availability of Luminex assay. METHODS: We analyzed data for 56 successive patients who underwent LTx before 2008 and were considered to not have anti-HLA Abs by then-available methods of detection at the date of their LTx. Pre-LTx sera from these patients were retested by Luminex assay. Using log-rank test, freedom from bronchiolitis obliterans syndrome (BOS) and graft survival were compared between patients with and without pre-LTx Luminex-detected anti-HLA Abs classes I and II and donor-specific Abs (DSA) classes I and II. RESULTS: Freedom from bronchiolitis obliterans syndrome was lower, and mortality was higher for patients with than those without pre-LTx Luminex-detected DSA class II (P=0.004 and P=0.007, respectively) but did not differ for patients with and without DSA class I or anti-HLA Abs class I or II. CONCLUSIONS: It suggests to avoid attributing graft with forbidden antigens to sensitized candidates with Luminex-detected DSA class II and to evaluate the role of specific posttransplantation protocols for LTx candidates who require emergency LTx.
