AI Article Synopsis

  • Kidney allograft rejection can lead to graft failure and is complicated by immunosuppressive treatments that increase infection and cancer risks.
  • A study was conducted to examine the effects of hydroxychloroquine on kidney transplant recipients who also have autoimmune diseases, as its impact on rejection was previously unknown.
  • The research found no significant difference in rejection or graft failure rates between kidney transplant patients treated with hydroxychloroquine and matched controls, indicating that hydroxychloroquine does not help prevent rejection in these patients.

Article Abstract

Kidney allograft rejection is a major issue because it causes graft failure and because immunosuppressive treatments used for its prevention increase the risk of infections and cancers. In systemic lupus patients, hydroxychloroquine is used to prevent immune flares with decreased doses of immunosuppressants. Hydroxychloroquine can be safely used in kidney transplant recipients when indicated for autoimmune disease, but its effect on allograft rejection is unknown. We hypothesized that it may prevent kidney allograft rejection. We conducted a nationwide retrospective propensity-matched study on kidney transplantations of patients treated with hydroxychloroquine in France between 2008 and 2018. We analyzed the incidence of allograft rejection or failure within the first year after transplantation. The rates of rejection or allograft failure were not different between the 188 patients treated with hydroxychloroquine at the time of transplantation and their propensity matched controls. Hydroxychloroquine treatment in association with standard immunosuppressive treatment does not prevent rejection in kidney allograft recipients.

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.

Transcriptome of capsular contracture around breast implants mimics allograft rejection: a matched case-control study.

Copenhagen University Hospital, Department of Plastic Surgery and Burns Treatment, Rigshospitalet, Copenhagen, Denmark.

Background: Capsular contracture is a frequent and severe complication following breast implant surgery. Although several theories on the pathophysiology exist, the exact molecular mechanisms remain unclear. This study aimed to identify the specific genes, signaling pathways, and immune cells associated with capsular contracture.

Aims: In cystic fibrosis lung transplant recipients (LTRs), graft dysfunction due to acute infections, rejection or chronic lung allograft dysfunction (CLAD) is difficult to distinguish. Characterisation of the airway inflammatory milieu could help detect and prevent graft dysfunction. We speculated that an eosinophil or neutrophil-rich milieu is associated with higher risk of CLAD.

Characteristic alterations in the urinary microbiome, or urobiome, are associated with renal transplant pathology. To date, there has been no direct study of the urobiome during acute allograft rejection. The goal of this study was to determine if unique urobiome alterations are present during acute rejection in renal transplant recipients.

Cytomegalovirus (CMV) infection in solid organ transplant (SOT) and hematopoietic cell transplant (HCT) recipients may increase the risk of rejection or allograft dysfunction, other infection(s), and morbidity and mortality. Treatment can be challenging due to medication-associated toxicities. Maribavir (MBV) is a promising option for the treatment of resistant or refractory (R/R) CMV infection in lieu of foscarnet (FOS), which has long been the recommended therapy for (val)ganciclovir-resistant infection.
