Nonadherence to immunosuppressive medications may partly explain the worse allograft outcomes among black recipients of renal transplants. In a prospective cohort study of recipients of deceased donor renal transplants, microelectronic cap monitors were placed on bottles of one immunosuppressive medication to (1) measure average daily percentage adherence during the first posttransplantation year and (2) determine the factors associated with adherence. A total of 278 transplant recipients who provided sufficient microelectronic adherence data were grouped into four categories of average daily percentage adherence: 95 to 100% adherence (41.0% of patients), 80 to 95% adherence (32.4%), 50 to 80% adherence (12.9%), and 0 to 50% adherence (13.7%). In the unadjusted ordinal logistic regression model, black race was associated with decreased adherence (odds ratio [

Analysis of data from a single center and the national UNOS database suggests that transplantation of liver allografts from HCV+ donors to HCV+ recipients results in graft survival comparable to HCV- grafts transplanted to HCV+ recipients. In contrast, recipient HCV positivity is an independent predictor of graft failure compared with patients transplanted for other causes of liver disease.
