Serum mannose-binding lectin (MBL) values were measured in 57 lung transplant recipients before and 20 months after lung transplantation. Each circle represents the MBL measured in one serum. The decrease in MBL values was significant and medians and 25–75% intervals are depicted pre- and post-lung transplantation. In the 45 patients who showed a decrease in MBL values after transplantation, no differences in native lung diseases were detected. Twelve patients (six cystic fibrosis and six emphysema) demonstrated an increase in MBL values after transplantation.
