Acute graft rejection in patients after heart transplantation can cause arrhythmias and acute angina pectoris with electrocardiographic ST-segment elevation. We report a case of a 53-year old female patient who had undergone cardiac transplantation 8 years previously. She developed bradycardia with co-existent ST-segment elevation caused by a histologically proven acute graft rejection. After administration of methylprednisolone and immune absorption leading to initial clinical improvement, the patient died unexpectedly. The reasons remain unclear, but a degeneration of the conduction system as well as impaired blood flow in the right coronary caused by cellular and humoral rejection most likely have both contributed.

Effects of shared decision-making on the prognosis of peritoneal dialysis patients.

Background: Chronic kidney disease (CKD) patients face critical decisions in choosing kidney replacement therapy such as hemodialysis (HD) or peritoneal dialysis (PD), which significantly affect their quality of life and health outcomes. Recent studies highlight the importance of shared decision-making (SDM) in helping patients understand their treatment options and make informed choices. SDM not only improves patient satisfaction and autonomy but also emphasizes the need for comprehensive pre-dialysis education to support optimal treatment selection.

Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.

There is no established treatment for late or chronic antibody-mediated rejection of a kidney graft. Rituximab-based treatment is not effective, since long-lived high-affinity plasma cells do not express CD20 and do not depend on previous maturation steps to generate donor-specific antibodies. Conversely, daratumumab, an anti-CD38 monoclonal antibody, directly targets plasma cells, with proven efficacy in multiple myeloma.
