Adult lung transplant recipients who underwent transplantation between 2007 and 2013 at the Medical University of Vienna were included. Using mass spectrometry (MS), serum samples were examined before transplantation (T1) and 12 months post-transplant (T2).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 102 patients (50 alemtuzumab, 34 ATG, 18 no induction), we identified significantly differentially expressed proteins over time and between groups at T2. In the alemtuzumab group, 40 proteins were differentially expressed (3 upregulated, 37 downregulated), in ATG, 22 proteins (3 upregulated, 19 downregulated), and none in the no-induction group. At T2, two proteins (fibulin-1 and fetuin-B) were downregulated between alemtuzumab and no induction, with no significant differences between alemtuzumab and ATG or ATG and no induction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Our findings suggest alemtuzumab may have a stronger effect on circulating proteome.
