Background: Pulmonary complications in immunocompromised patients are often fatal. Empirical treatment is usually applied based on the clinical and radiological findings because of the risk of the aggressive diagnostic procedures such as open lung biopsy. However, recent advancements in operative procedures and perioperative management has decreased the procedure-related risks. We have prospectively analyzed the risks and benefits of the early application of open lung biopsy in such patients. Material and Method: Forty-two consecutive immunocompromised patients with critical pulmonary complications were included from June, 1996 to December, 1999. The definition of the immunocompromised is as those with chemotherapy and/or other modality for hematologic disorders, with usage of immunosuppressive drug after transplantation, with usage of steroid for more than 1 month, and with primary immunodeficiency disorders. The indication of open lung biopsy was those with no significant improvement after a week of aggressive application of empirical treatment or with rapidly aggressive process. The underlying disease included hematologic disorder(31 patients), post-transplantation(3 patients), chemotherapy for solid tumor(2 patients), and others(6 patients). Operations were done through thoracotomy(conventional or mini-) or VATS.

We have performed left lung transplantations in 15 dogs for one year and six months from June, 1990 to December, 1991 at the Repartment of Thoracic and Cardiovascular Surgery Yonsei University College of medicine, Seoul, Korea. These dogs were sacrificed at from operative day to post-operative 15 days when their general conditions were deteriorated. The gross findings of the transplanted lungs were thrombi in left atrium in three cases, partial occlusion of pulmonary artery or pulmonary veins in three cases, hemorrhage at pulmonary arterial anastomotic site in one case and bronchial anastomotic stenosis in two cases, bronchial anastomotic rupture in one case % no abnormal gross findings in four cases. The microscopic findings of the transplanted lungs were hemorrhagic infarction in one case, perivascular hemorrhage or pulmonary edema in two cases, peribronchial inflammatory cell infiltration & pneumonia in three cases, and alveolar type rejection with infiltration of type II pneumocytes and septal thickening in 3 cases. And also there were no abnormal findings including rejection or inflammatory evidences in six cases. The one among these six dogs survived to 15 days without evidence of rejection or inflammatory reaction & died due to postoperative care accident.

Purpose : This study aimed to identify the factors affecting the quality of life of lung transplant patients. Method : The participants were patients who received lung transplants at a general hospital in City Y. Data were collected through structured questionnaires from June 2023 to August 2023. General characteristics, lung transplantation-related characteristics, quality of life, functional disability, treatment compliance, social support, anxiety, and depression-were measured. For data analysis, hierarchical multiple regression was performed using SPSS/WIN 29.0. Results : In the final model, quality of life was associated with income, self-help group attendance, functional disability, social support, treatment compliance, and anxiety and depression. Together, they explained 61.2% of the total variance in the results. Conclusion : Our findings suggest that improving lung transplant patients' quality of life requires active intervention in stress management to perform treatment instructions well, a social support system that can help them financially, and encouraging and participating in social activities as patients.

Despite the improvements in supportive care, early and late hematopoietic stem cell transplantation-related complications still remain a significant cause of morbidity and mortality. Pulmonary complications occur in 40-60% of patients who undergo allogeneic hematopoietic stem cell transplantation. Late-onset noninfectious pulmonary complications can occur months and even years after transplantation. Interstital lung disease has also been reported to be a late post-transplant complication. Exposure to cytotoxic drugs and/or irradiation has been implicated as a cause of pulmonary toxicity including pulmonary fibrosis. We report a case of an 18-year-old female with non-classifiable interstitial pneumonia that manifested eight and a half years after allogeneic hematopoietic stem cell transplantation. The condition worsened rapidly and the patient eventually died.

Background: Due to the paucity of suitable donor organs for lung allotransplantation, a number of techniques have been developed to improve the lung preservation. Ultrastructural studies of the morphologic changes of the flushing, preservation and reperfusion injury in donor lungs have rarely been reported. Methods: Adult dogs (n=46) were matched as donors and recipients for the single lung transplantation. The donor lungs were preserved after flushing with preservation solution and transplanted after 20-hours of preservation at $10^{\circ}C$. Ultrastructural features of the lung were examined after flushing, preservation and 2 hours after lung transplantation (reperfusion) respectively. Results: Electron microscopy after flushing showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. The endothelial cells showed protrusion of tactile-like structures into the lumina, blebs or vacuoles of the cytoplasm After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. Scanning electron microscopic examination of the pulmonary parenchyma showed focally alveolar collapse and focal consolidation after the preservation and more prominent changes after the reperfusion procedure. The lungs preserved with low potassium dextran glucose solution, with additional prostaglandin $E_1(PGE_1)$ and verapamil(VP) showed relatively well preserved ultrastructures compared with those which were preserved with modified Euro-Collins or University of Wisconsin, and with additional $PGE_1$ and/or VP. Conclusion: The ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage was occurred during the reperfusion. The reperfusion injury resulted in prominent pulmonary parenchymal alterations with a pattern of acute lung injury.
