Abstrakt: The utility of measuring serum periostin levels for predicting the occurrence of bronchiolitis obliterans syndrome (BOS) after lung transplantation remains underexplored. We analyzed differentially expressed genes (DEGs) between initially transplanted lung tissue and lung tissue with BOS from four patients. Periostin levels were assessed in 97 patients who had undergone lung transplantation 1 year post-transplantation and at the onset of BOS. The association between periostin levels and BOS, as well as their correlation with the decline in forced expiratory volume in one second (FEV1), was evaluated. Periostin levels in the BOS group were significantly higher than those in the control group (p < 0.001) and the stable group (p < 0.001). Periostin levels at the onset of BOS were significantly higher than those 1 year post-transplantation in the BOS group (p < 0.001). The serum periostin levels at the time of BOS diagnosis showed a positive correlation with the reduction in FEV1 (%) (r = 0.745, p < 0.001). The increase in the serum periostin levels at the time of BOS diagnosis compared with those 1 year post-transplantation was positively correlated with reduction in FEV1 (%) (r = 0.753, p < 0.001). Thus, serum periostin levels may serve as biomarkers for predicting a decline in lung function in patients with BOS after lung transplantation. [ABSTRACT FROM AUTHOR]
