Abstract

Background

Delayed graft function is a manifestation of acute kidney injury unique to transplantation usually related to donor ischemia or recipient immunological causes. Ischemia also considered the most important trigger for innate immunity activation and production of non-HLA antibodies. While ischemia is inevitable after deceased donor transplantation, this complication is rare after living transplantation. Heterologous Immunity commonly used to describe the activation of T cells recognizing specific pathogen-related antigens as well unrelated antigens is common post-viral infection. In transplant-setting induction of heterologous immunity that cross-react with HLA-antigens and subsequent reactivation of memory T cells can lead to allograft rejection.

Methods

Here we describe a non-sensitized child with ESRD secondary to lupus nephritis and recent history of COVID-19 infection who experienced 17 days of anuria after first kidney living transplantation from her young HLA-haploidentical uncle donor. Graft histology showed acute cellular rejection, evidence of mild antibody-mediated rejection and vascular wall necrosis in some arterioles suggesting possibility of intraoperative graft ischemia. Both pre- and post-transplant sera showed very high level of several non-HLA antibodies.

Results

The patient was treated for cellular and antibody-mediated rejection while maintained on hemodialysis before her graft function started to improve on day seventeen post transplantation.

Conclusion

The cellular rejection likely trigged by ischemia that activated T-cells-mediated immunity. The high level of non- HLA-antibodies further aggravated the damage and the rapid onset of rejection may be partly related to memory T-cell activation induced by heterologous immunity.

CONFLICT OF INTEREST

The authors confirm that there are no conflicts of interest.
