PURPOSE: Inflammatory changes during lung ischemia-reperfusion injury (IRI) are related to the activation of the extracellular signal-regulated kinase (ERK)1/2 signaling pathway. Sprouty-related EVH1 (enabled/vasodilator-stimulated phosphoprotein homology 1)-domain-containing proteins (SPREDs) are known inhibitors of ERK1/2 signaling. The role of SPRED2 in lung IRI was examined in a left hilar clamp mouse model. METHODS: C57BL/6 wild-type (WT) and Spred2-/- mice were used in the left hilar clamp model. Experimental groups underwent 30 min of left hilar clamping followed by 1 h of reperfusion. U0126, an ERK1/2 inhibitor, was administered to Spred2-/- mice with reperfused lungs. RESULTS: The partial pressures of oxygen of the Spred2-/- mice after reperfusion were significantly worse than those of WT mice (p < 0.01). Spred2-/- mice displayed more severe injuries than WT mice with increased neutrophil infiltration observed by a histological evaluation and flow cytometry (p < 0.001). This severe inflammation was inhibited by U0126. In addition, the rate of ERK1 activation was significantly higher in the lungs of Spred2-/- mice after reperfusion than in WT mice according to a Western blot analysis (p < 0.05). CONCLUSION: The activation of the ERK1/2 signaling pathway influences the severity of lung IRI, causing inflammation with neutrophil infiltration. SPRED2 may be a promising target for the suppression of lung IRI.

Donor-derived cell-free DNA (dd-cf-DNA) has been shown to be an informative biomarker of rejection after lung transplantation (LT) from deceased donors. However, in living-donor lobar LT, because small grafts from blood relatives are implanted with short ischemic times, the detection of dd-cf-DNA might be challenging. Our study was aimed at examining the role of dd-cf-DNA measurement in the diagnosis of primary graft dysfunction and acute rejection early after living-donor lobar LT. Immediately after LT, marked increase of the plasma dd-cf-DNA levels was noted, with the levels subsequently reaching a plateau with the resolution of primary graft dysfunction. Increased plasma levels of dd-cf-DNA were significantly correlated with decreased oxygenation immediately (p = 0.022) and at 72 hours (p = 0.046) after LT. Significantly higher plasma dd-cf-DNA levels were observed in patients with acute rejection (median, 12.0%) than in those with infection (median, 4.2%) (p = 0.028) or in a stable condition (median, 1.1%) (p = 0.001). Thus, measurement of the plasma levels of dd-cf-DNA might be useful to monitor the severity of primary graft dysfunction, and plasma dd-cf-DNA could be a potential biomarker for the diagnosis of acute rejection after LT.

PURPOSE: The lung allocation score (LAS) has been generally recognized as a contributor to the overall survival in lung transplant candidates. However, donor-related risks have never been taken into consideration in previous research that validated the LAS. This study aimed to determine whether or not the role of the LAS as a predictor of the posttransplant outcome is influenced by the quality of the donor lungs. METHODS: We retrospectively reviewed 108 patients who underwent lung transplantation at Okayama University Hospital since 1998. The cohort was divided into two groups based on the lung donor score (DS; ≤ 4/> 4). Correlations between the LAS and posttransplant outcomes were investigated in both groups. RESULTS: In the high-DS group, an elevated LAS was strongly associated with posttransplant PaO2/FiO2 (p = 0.018). However, in the low-DS group, no correlation was found between them. There was no significant difference in the long-term survival according to the LAS in the low-DS group. The LAS effectively predicted the posttransplant outcome only when lungs with DS > 4 were transplanted; the LAS was not reliable if high-quality lungs were transplanted. CONCLUSION: Lung transplantation can be feasible and provides a survival benefit even for high-LAS patients if lungs from a low-risk donor are transplanted.

Myoepithelioma is a rare neoplasm usually occurring in the salivary glands or the mammary glands but also, more rarely, in the thoracic cavity. The diagnosis of myoepithelioma is based on the presence of histological and immunohistochemical characteristics of myoepithelioma, but in unusual locations, the diagnosis is challenging. For such cases, cytogenetic approaches have been developed as helpful tools for the diagnosis. We report a surgical case of 51-year-old woman with myoepithelioma occurring in the posterior mediastinum that harbored the Ewing sarcoma breakpoint region1 (EWSR1) gene rearrangement. To the best of our knowledge, this is the first report of a myoepithelioma occurring in the posterior mediastinum. In this case, the patient underwent the thoracoscopic surgery for a diagnostic tumorectomy and was diagnosed as myoepithelioma based on the following immunohistological findings. Considering the unusual location, we additionally performed a cytogenetic analysis to confirm the presence of the EWSR1 gene rearrangement, which is a genetic characteristic of myoepithelioma.

PURPOSE: Airway complications (ACs) after living-donor lobar lung transplantation (LDLLT) could have different features from those after cadaveric lung transplantation (CLT). We conducted this study to compare the characteristics of ACs after LDLLT vs. those after CLT and investigate their impact on outcomes. METHODS: We reviewed, retrospectively, data on 163 recipients of lung transplantation, including 83 recipients of LDLLT and 80 recipients of CLT. RESULTS: The incidence of ACs did not differ between LDLLT and CLT. The initial type of AC after LDLLT was limited to stenosis in all eight patients, whereas that after CLT consisted of stenosis in three patients and necrosis in ten patients (p = 0.0034). ACs after LDLLT necessitated significantly earlier initiation of treatment than those after CLT (p = 0.032). The overall survival rate of LDLLT recipients with an AC was significantly lower than that of those without an AC (p = 0.030), whereas the overall survival rate was comparable between CLT recipients with and those without ACs (p = 0.25). CONCLUSION: ACs after LDLLT, limited to bronchial stenosis, require significantly earlier treatment and have a greater adverse impact on survival than ACs after CLT.

Although the number of patients developing pulmonary complications after hematopoietic stem cell transplantation (HSCT) necessitating lung transplantation (LT) is increasing, a little information is available about factors influencing the prognosis after LT in these patients. Corticosteroids represent the first-line therapy for pulmonary complications after HSCT; however, prolonged corticosteroid treatment prior to LT increases the potential risks of LT. In this study, we assessed the effect of preoperative corticosteroid therapy on long-term survival in patients undergoing LT after HSCT. We retrospectively investigated data from 13 patients who had received high-dose corticosteroid therapy and nine who had received low-dose corticosteroid therapy prior to LT for pulmonary complications after HSCT. Other than the preoperative corticosteroid dose, patient clinical characteristics did not differ. The incidence of postoperative complications within the first year after LT was significantly lower in the low-dose corticosteroid group (p = 0.026). Survival after LT was also significantly better in the low-dose corticosteroid group than in the high-dose corticosteroid group (p = 0.034). In recipients of LT after HSCT, preoperative low-dose corticosteroid use, as compared to preoperative high-dose corticosteroid use, could limit the risks of postoperative complications developing within the first year after the LT, leading to improved long-term survival after LT.

Pneumatosis intestinalis, which could complicate a spectrum of clinical conditions ranging from benign to life-threatening, is a rarely encountered complication after lung transplantation (LT). We describe two cases in which PI developed as a complication following LT for pulmonary graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT). In addition to the long-term immunosuppression administered for pulmonary GVHD, the intense immunosuppression needed after LT might increase the risk of PI in lung transplant recipients after HSCT. Conservative therapy should be considered for the treatment of PI developing after LT.

Adverse cardiovascular events after lung transplantation (LT) increase the mortality in patients with pulmonary arterial hypertension (PAH). Long-term intravenous prostacyclin is the usual treatment in severe patients with PAH, but it may increase the risk of hemorrhage due to its antiplatelet aggregation effect or thrombocytopenia. We investigated the impact of length of intravenous prostacyclin therapy on acute adverse cardiovascular events including hemorrhagic complication after LT. We retrospectively compared the incidence of adverse events (death, intrathoracic hematoma and bleeding, cardiac congestion or shock, cerebral infarction and pulmonary embolism) within 30 days after LT between no/short-term (median 0.6 years, n = 13) and long-term (median 3.7 years, n = 15) intravenous prostacyclin groups. There were no differences in the dose of intravenous prostacyclin and pulmonary artery pressure between the two groups. Among 22 adverse events (0.8 ± 1.1 events/patient), 4 events occurred in the no/short-term intravenous prostacyclin group and 18 occurred in the long-term intravenous prostacyclin group. The event rate per patient in the long-term intravenous prostacyclin group (1.2 ± 1.3 events/patient) was significantly higher than that in the no/short-term intravenous prostacyclin group (0.3 ± 0.5 events/patient) (P < 0.05). Intrathoracic hematoma and bleeding was the most frequent adverse event (9 events, 41%). Preoperative long-term intravenous prostacyclin therapy increases acute adverse cardiovascular events after LT in patients with PAH.

BACKGROUND: Lung transplants have produced very favorable outcomes for patients with interstitial lung disease (ILD) in Japan. However, because of the severe donor lung shortage, patients must wait approximately 2.5 years before they can undergo transplantation and many candidates die before allocation. We reveal the clinical characteristics of Japanese patients with ILD who are candidates for lung transplants and the risk factors for early death while on the waiting list. METHODS: We retrospectively reviewed the clinical data of patients registered in the Japan Organ Transplant Network from Okayama University Hospital who are candidates for cadaveric lung transplants for ILD between 1999 and 2015. RESULTS: Fifty-three patients with ILD were included (24 patients with idiopathic pulmonary fibrosis and 29 others). They had severe pulmonary dysfunction and low exercise tolerability. The median waiting time for transplantation was 462 days, and 22 patients died before allocation. Patients who died before 462 days without undergoing transplantation had more severe dyspnea, shorter 6-minute walk distance (6MWD), and lower performance status than those who waited ≥462 days. CONCLUSIONS: Japanese candidates for cadaveric lung transplants for ILD have severe pulmonary dysfunction. Severe dyspnea, short 6MWD, and low performance status are risk factors for early death while on the waiting list.
