Popis: Background Esophageal pathology has been identified as a bad prognostic factor in lung transplantation (LTx). This study aims to assess the esophageal disorders present post-LTx, under treatment with proton pump inhibitors, and their putative impact on the graft. Methods Prospective, observational study of LTx patients. Digestive factors were assessed by manometry and pH-metry at 6 months post-LTx and under proton pump inhibitor treatment. We assessed the association between esophageal disorders and graft function and acute rejection (AR) and chronic lung allograft dysfunction (CLAD). Results Out of 76 post-LTx patients, 27% showed gastroesophageal reflux disease (GERD), 55% showed inadequate gastric inhibition, and 59% showed esophageal motility disorders (EMDs). We observed a greater incidence of AR from 3 months post-LTx in the presence of EMD (P ≤ .05). No significant differences were observed in GERD or EMD prevalence or in survival between patients with or without CLAD. The maximum forced expiratory volume in 1 second (FEV1) achieved after bilateral LTx was significantly (P = .022) lower in patients with EMD vs without EMD. Conclusion At 6 months post-LTx, there is a high percentage of esophageal disorders (GERD and EMDs). No esophageal disorder is associated with CLAD or with survival, although EMDs are associated with a greater incidence of AR and lower graft function.
