One hundred and two (128 eyes) patients with stage 4 ocular burns underwent examinations. One-stage therapeutic keratoplasty was used in 67 (67.7%) patients. Retransplantation was made in 35 (34.3%) of patients due to graft rejection. According to the study, the more severe the clinical course of burn lesions is (cases that necessitated transplantation in the present research), the more pronounced changes are observed in the body immune reactivity of victims. In particular, the below peculiarities were observed: a progressing reduction of the contents of lymphocytes' and of B-lymphocytes; and a diminishing phagocytic activity of neutrophils in the peripheral blood registered at the terminal treatment stage in the patients after retransplantation versus the 1st-group patients with a more favorable clinical course. The compensatory increase of T-lymphocytes, T-helpers and of IgA, IgG was found to be less pronounced in group 2. A notably more intense sensitization response of the body to corneal antigens was established in the patients after retransplantation, which was a basis for using this index as a prognostication test in respect to the graft rejection crisis.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal malignancy of the gastrointestinal tract. Most GIST harbor mutations in oncogenes, such as KIT, and are treated with tyrosine kinase inhibitors (TKI), such as imatinib. Most tumors develop secondary mutations inducing drug resistance against the available TKI, which requires novel therapies.

Background: Lung transplantation (LuTX) can be the last resort for patients with end-stage lung diseases. In the last decades, improvements were implemented in transplant medicine, from immunosuppression throughout preservation of the donor organ to enhance lung allograft survival. This retrospective study aims to illustrate the development of the LuTX-program at the University Hospital of Munich, LMU, Munich, Germany, since its launch in 1990 by depicting and comparing postoperative outcome.

Introduction: Liver retransplantation (reLT), which is the only treatment for liver graft failure, remains challenging not only because of its technical nature but also because it is performed in high-risk patients.
Methods: Nineteen patients who underwent reLT (second LT, n = 18; third LT, n = 1) between 1999 and 2021 were divided into two groups according to the graft laterality between prior transplantation and reLT (ipsilateral group, n = 9; contralateral group, n = 10). The aim of this study was to evaluate the short- and the long-term outcomes of patients who underwent living donor reLT and compared graft survival between ipsilateral and contralateral grafts.

Background: Kidney retransplantation offers a valuable treatment option for patients who experience graft failure after their initial transplant. There is an increasing number of patients undergoing multiple retransplants. However, the impact of multiple kidney retransplants on post-transplant outcomes remains unclear.
