Unmasking of immunoglobulin a deposits posttransplant due to COVID-19 AKI-incidental or causal – A nephrologists' dilemma a case report

Abstract

COVID-19 is a global pandemic with the chronically immunosuppressed transplant recipients being the most vulnerable both to infection as well as complications of COVID-19. Here, we report a case of live-related renal allograft recipient who presented with complaints of loose stools and new-onset graft dysfunction 2 years posttransplant. He tested positive for COVID-19 infection. On allograft biopsy, there were significant immunoglobulin A (IgA) deposits with no evidence of rejection or ATN or crescents or significant chronicity. The initial pretransplant biopsy of the recipient had revealed chronic glomerulonephritis with nil deposits. The donor had no evidence of hematuria or hypertension and had a preserved GFR. We, therefore, considered the possibility of the unmasking of IgA deposits posttransplantation diagnosed in a recipient with COVID-19 infection.
