The research assessed the incidence of biopsy confirmed recurrent IgA nephropathy and identified clinical and donor related factors associated with recurrence risk. Biopsy confirmed recurrent IgA nephropathy occurred in 14% of patients, with a cumulative incidence of 16% at 10 years after transplantation. The study therefore identified recurrent nephropathy as an important factor associated with poorer graft outcomes after transplantation. Findings Highlight Need for Further ResearchThe investigators concluded that recurrent nephropathy remained a clinically significant challenge after kidney transplantation.
