A 51-year-old immunocompetent male with a history of Fuchs' endothelial dystrophy and immature cataract who underwent Descemet's stripping automated endothelial keratoplasty with intraocular lens implantation in both eyes presented with redness and defective vision of 1-day duration in his left eye. Slit lamp examination revealed coarse superficial punctate lesions with graft edema. He was diagnosed with acute graft rejection and treated with topical steroids. Two days later, symptoms worsened in his left eye with the involvement of his right eye showing a similar clinical picture. An infectious etiology was suspected and in vivo confocal microscopy ordered, which revealed hyperreflective dots, highly suggestive of microsporidial spores. The patient was prescribed topical fluconazole 0.3% in both eyes. This unique presentation of bilateral graft edema following microsporidial keratoconjunctivitis in postgraft patients requires a high index of suspicion as it can be easily be mistaken for and mismanaged as acute graft rejection.

Background: Belatacept is approved for the prophylaxis of organ rejection in Epstein-Barr virus (EBV)-seropositive kidney transplant recipients and is associated with a risk of post-transplant lymphoproliferative disorder (PTLD).
Methods: Data from the Organ Procurement and Transplantation Network were used to examine patterns of belatacept use, describe patient characteristics, and estimate risk of PTLD in EBV-seropositive, kidney-only transplant recipients receiving belatacept- or calcineurin inhibitor (CNI)-based immunosuppression as part of US Food and Drug Administration-mandated safety monitoring.
Results: During the study period (June 15, 2011-June 14, 2016), 94.

Background: The use of donor kidneys with acute kidney injury (AKI) aims to expand the organ pool, but uncertainty remains regarding their outcomes across different Kidney Donor Profile Index (KDPI) groups and preservation methods.
Methods: We retrospectively analyzed 108 160 deceased donor kidney transplants from the OPTN database, focusing on adult recipients of kidneys from donors with or without AKI between December 2014 and December 2022. Propensity matching was used for each KDPI group (1-20, 21-59, 60-84, and 85-100), comparing donors with AKIN stages 0-1 to AKIN stages 2-3.

Background: Long-term renal allograft acceptance has been achieved in macaques using a transient mixed hematopoetic chimerism protocol, but similar regimens have proven unsuccessful in heart allograft recipients unless a kidney transplant was performed simultaneously. Here, we test whether a modified protocol based on targeting CD154, CD2, and CD28 is sufficient to prolong heart allograft acceptance or promote the expansion of regulatory T cells.
Methods: Eight macaques underwent heterotopic allo-heart transplantation from major histocompatibility complex-mismatched donors.

Purpose: To report the surgical approach of a Lucia keratoprosthesis (KPro) on a sclerocorneal graft in the setting of recurrent graft rejection and perilimbal scleral thinning.
Methods: A case report.
Results: We report the case of a 26-year-old man with a history of herpes simplex keratitis, 2 penetrating keratoplasties, graft failure, secondary glaucoma, and a conjunctival flap in the right eye who underwent a Lucia KPro, lens extraction, glaucoma drainage device, and pars plana vitrectomy.

Background: The viability of the liver pre-transplant depends on the type of donor, age, medical history, circumstances of death, result of analytics, and complementary exploration of the abdominal cavity. Abdominal ultrasound is the initial option for the assessment of previously unknown liver disease, such as the qualitative determination of hepatic steatosis . The presence of hepatic steatosis is considered a risk factor for graft failure after liver transplantation, therefore, at the time of clinical assessment of the donor or its presence in the macroscopic assessment in the operating room can be cause for rejection of the organ by the transplant teams.
