Vascular rejection after renal transplantation is connected with a higher frequency of allograft dysfunction or graft loss. Plasmapheresis as an adjunctive therapy in the treatment of humoral mediated acute graft rejection was compared with protein A immunoadsorption. Eleven patients with acute graft rejection and high titers of cytotoxic HLA-Ab and/or signs of vascular rejection at graft biopsy (performed in 9 patients) have been treated. Six of them have a stable graft function, the longest graft survival until now is 41 months, four are back on haemodialysis and one patient died from CMV-pneumonia with a stable graft function 9 months after transplantation. We conclude that IA is a useful adjunctive therapy in the treatment of vascular rejection after renal transplantation. Further investigations are necessary to optimize criteria for inclusion.

Polyomavirus BK (BKPyV)-associated nephropathy (BKPyV-nephropathy) remains a significant cause of premature kidney allograft failure. In the absence of effective antiviral treatments, current therapeutic approaches rely on immunosuppression (IS) reduction, possibly at the risk of inducing alloimmunity. Therefore, we sought to explore the long-term effects of a tailored viro-immunologic surveillance and treatment program for BKPyV on the development of alloimmunity and kidney graft outcome.

Objective: To investigate the clinical efficacy of percutaneous prying combined with modified rotary reduction with needle in the treatment of supracondylar fracture of humerus in Gartland type Ⅳ children, and to evaluate the postoperative elbow joint function, the incidence of elbow varus deformity and the application prospect of this technique.
Methods: A total of 98 children diagnosed with Gartland type Ⅳ supracondylar humeral fractures between June 2020 and January 2023 were included in this study, comprising of 57 males and 41 females. The age ranged from 2 to 14 years old with an average of (6.

Antibody-mediated rejection (ABMR) remains a leading cause of graft loss during kidney transplantation. Ischemia reperfusion injury (IRI) has been reported to promote T-cell proliferation, leading to B-cell activation and subsequent production of donor-specific antibodies (DSA), which target antigens on the vascular endothelium. We hypothesize that a novel therapeutic strategy targeting highly toxic reactive oxygen species could mitigate oxidative stress and immune responses associated with IRI.

Background: The long-term stability of allograft or native bone in facial vascularized composite allograft (fVCA) recipients is unclear. This study quantified long-term bone volume changes in facial transplants.
Methods: Computed tomography scans of eight fVCA recipients (2011-2023) were analyzed with Materialise Mimics.
