Immunopathogenesis of corneal graft rejection. [PDF]
Indian J Ophthalmol, 2023 The most common cause of corneal graft failure is corneal graft rejection (CGR). Although cornea is one of the immune-privileged sites, it can still get a rejection episode due to a breach in its natural protective mechanism. Both anatomical and structural properties of cornea and anterior chamber contribute toward its immune tolerance.

Graft rejection in component keratoplasty. [PDF]
Indian J Ophthalmol, 2023 Among the various indications for keratoplasty, failed graft is one of the commonest indications in many published series. It is well known that the major cause of graft failure is endothelial rejection. In the last two decades, there has been a major paradigm shift in the surgical management of corneal diseases, and component keratoplasty has emerged ...

Graft rejection in pediatric penetrating keratoplasty: Clinical features and outcomes
Oman Journal of Ophthalmology, 2015 Purpose: Early presentation of rejection facilitates early initiation of treatment which can favor a reversible rejection and better outcome. We analyzed the incidence, clinical features including rejection-treatment period and outcomes following graft ...

Acute graft rejection in a COVID-19 patient: Co-incidence or causal association?
Indian Journal of Ophthalmology, 2021 A 32-year-old man with a clear and compact graft following a penetrating keratoplasty 6 years back, developed an episode of acute graft rejection, coinciding with the COVID-19 disease.

Management and prevention of corneal graft rejection. [PDF]
Indian J Ophthalmol, 2023 The management of an episode of corneal graft rejection (CGR) is primarily by corticosteroids. Immunomodulators are useful for long-term immunosuppression and in dealing with cases of high-risk (HR) corneal grafts. The classical signs of CGR following penetrating keratoplasty (PKP) include rejection line, anterior chamber (AC) reaction, and graft edema.

Machine learning methods to identify risk factors for corneal graft rejection in keratoconus [PDF]
Scientific ReportsMachine learning can be used to identify risk factors associated with graft rejection after corneal transplantation for keratoconus. The study included all keratoconus eyes that underwent primary corneal transplantation from 1994 to 2021.

Specific tissue graft rejection in earthworms
Transplantation, 1970 Earthworms are capable of destroying antigenic tissues. Autogeneis transplants healed in regularly and remained permanently viable. Xenografts, by contrast, were cicatrized but eventually rejected. Intrafamilial transplants survived longer than interfamilial ones.

Circulating donor-derived cell-free DNA as a marker for rejection after lung transplantation
Frontiers in Immunology, 2023 ObjectiveRecently, circulating donor-derive cell free DNA (dd-cfDNA) has gained growing attention in the field of solid organ transplantation. The aim of the study was to analyze circulating dd-cfDNA levels in graft rejection, ACR and AMR separately for ...

Indian Journal of Transplantation, 2022 Background: Renal allograft rejection is a major cause of graft dysfunction, and it is a predictor of long-term allograft loss. Advances in immunosuppression have decreased the influence of acute rejection on graft survival.
