BACKGROUND: Non-adherence with immunosuppressive medications can result in allograft rejection and eventually allograft loss. METHODS: In a racially diverse population, we utilized microelectronic cap monitors to determine the association of adherence with a single immunosuppressive medication and kidney allograft outcomes post-transplantation. This prospective cohort study enrolled 243 patients from eight transplant centers to provide adherence and kidney allograft outcomes data. To determine the association of adherence with change in estimated glomerular filtration rate (eGFR), we fit mixed effects models with the outcome being change in eGFR over time. We also fit Cox proportional hazards models to determine the association of adherence with time to persistent 25% and 50% decline in eGFR. RESULTS: The distribution of adherence post-transplant was as follows: 164 (68%), 49 (20%), and 30 (12%) had >85-100%, 50-85%, and <50% adherence, respectively. Seventy-nine (33%) and 36 (15%) of the subjects experienced a persistent 25% decline in eGFR or allograft loss and 50% decline in eGFR or allograft loss during follow-up. Adherence was not associated with acute rejection or 25% decline or 50% decline in eGFR. In the adjusted and unadjusted model, adherence and black race were not associated with change in eGFR over time. CONCLUSIONS: Non-adherence with a single immunosuppressive medication was not associated with kidney allograft outcomes.
