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. [ncbi.nlm.nih.gov]

In the so-called indirect pathway of allorecognition, recipient T lymphocytes recognize antigens of the graft donor after they are presented by the recipient’s own antigen-presenting cells. [humpath.com]

The physiological function of the MHC molecules is to present antigenic peptides to T cells, since the T lymphocytes only recognize antigen when presented in a complex with an MHC molecule. [emedicine.medscape.com]

CONCLUSIONS: Prednisolone remains the treatment of choice for management and treatment of graft rejection; however, since the introduction of difluprednate, its use has declined slightly since the introduction of difluprednate. [ncbi.nlm.nih.gov]

In our patient, the prophylactic use of LAT from HLA-matched donors and AMT before PK, may result in a better prognosis of corneal graft survival. [ncbi.nlm.nih.gov]

Prognosis Graft rejection/failure is often a life-threatening complication. [clinicaladvisor.com]

When the organ donor is not the recipient themselves or a genetically identical twin, the immune response to the new organ becomes extremely important to prognosis. [stomponstep1.com]

AR-CGI rendering serum PARP1 as a biomarker for early prognosis. [omicsonline.org]

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. [ncbi.nlm.nih.gov]

In this study, we attempted to identify candidate serum biomarkers that could predict kidney allograft rejection/injury, regardless of its etiological and therapeutic heterogeneity. [omicsonline.org]

CORTES Study Group Risk factors for graft failure after penetrating keratoplasty: 5-year follow-up from the corneal transplant epidemiological study. Cornea. 2011;Dec;30(12): 1328–35. pmid:21926910 View Article PubMed/NCBI Google Scholar 5. [journals.plos.org]

Pathophysiology Graft rejection is a major cause of graft failure and is due to an immune response of residual post immune cells against donor hematopoietic cells. [clinicaladvisor.com]

Acute rejection can be classified according to pathophysiological changes (cellular‐interstitial, vascular, antibody‐endothelial) or underlying immunologic mechanisms (adaptive or innate immune injury) or severity (histologic injury graded by the Banff [els.net]

Panel B shows possible interactions between the major identified marker PARP1 and its multiple interacting partners that can be related to the graft pathophysiology (PARP1, MAPK1 and NFATC1 highlighted). [omicsonline.org]

“Both prevention and treatment of graft rejection are correlated with the patient’s risk category,” Dr. Mastropasqua said. “Topical steroids prevent allograft rejection by inhibiting leukocyte migration into the cornea. [healio.com]

Alexion is investigating Soliris for the prevention of acute antibody-mediated rejection (AMR) in kidney transplant recipients, and for the prevention of delayed graft function (DGF) in patients receiving deceased donor kidney transplants. [news.alexionpharma.com]

In pre-clinical studies conducted by the researchers, a one-time, local injection of the hydrogel-drug combo prevented graft rejection for more than 100 days. [news.harvard.edu]

To determine if the use of combined HLA matched limbal stem cells allograft with amniotic membrane transplantation (AMT) is a safe and effective prophylactic surgical procedure to prevent corneal graft after penetrating keratoplasty (PK). [ncbi.nlm.nih.gov]

This treatment prevents acute rejection of the transplants, but at a high cost: Most patients develop opportunistic infections and cancer. [immune-tolerance.fr]
