Popis: | The impact of de-novo donor-specific anti-HLA antibodies (DSA) on patient and graft survival after lung transplantation remains controversial. We analyzed DSA that developed at Day 7 and Month (M) 1, M3, M6 and M12 after lung transplantation and evaluated their impact on chronic lung allograft dysfunction (CLAD) development and survival.One hundred thirty-four patients who underwent lung transplantation at our institution between November 2007 and August 2013 were included in this study. During the first post-transplant year, 82 (61%) patients developed de novo DSA and 52 (39%) patients did not. Three mean fluorescence intensity (MFI) intervals were used to define scores of anti-HLA antibody positivity: score 4 if MFI was 500 to 1,000; score 6 if MFI was 1,000 to 3,000; and score 8 if MFI was ≥3,000. Patients' records were retrospectively reviewed.DSA with MFI scores of ≥4 (hazard ratio [HR] 2.21, 95% confidence interval [CI] 1.08 to 4.54, p = 0.03), 6 (HR 2.63, 95% CI 1.27 to 5.20, p0.01) and 8 (HR 2.83, 95% CI 1.42 to 5.67, p0.01) at M1; female gender (HR 0.49, 95% CI 0.28 to 0.87, P = 0.01); and with post-operative extracorporeal membrane oxygenation (HR 0.09, 95% CI 0.01 to 0.28, p = 0.02) were significantly associated with CLAD. Multivariate analysis identified score 8 at M1 (HR 2.71, 95% CI 1.34 to 5.47, p0.01) as an independent risk factor for mortality. Overall, 1-, 3- and 5-year survival rates were 76%, 52% and 41% compared with 84%, 74% and 70% for patients with or without de-novo DSA at M1, respectively (p = 0.02).Early de-novo DSA may significantly impact long-term outcomes after lung transplantation and should therefore prompt regular screening. |
