    Background. Our aim was to study the impact of clinical acute rejection (CR) and subclinical rejection (SR) on outcomes in kidney transplant recipients treated with rapid steroid withdrawal (RSW). Methods. All patients who received a living or deceased donor kidney transplant and were treated with RSW were included. The primary outcome was death-censored graft survival. Biopsies with Banff borderline changes were included with the rejection groups. Results. 457 kidney transplant recipients treated with RSW were included; 46 (10%) experienced SR, and 36 (7.8%) had CR. Mean HLA mismatch was significantly higher in the CR group. The Banff grade of rejection was higher in the CR group. There was a larger proportion of patients in both rejection groups with the combination of IFTA and persistent inflammation on the follow-up protocol biopsy done at 1 year. The estimated 5-year death-censored graft survival was 81% in SR, 78% in CR, and 97% in the control group (P < .0001). Significant differences were observed in allograft survival between the CR and control group (HR 9.06, 95% CI 3.39–24.2) and between the SR and control group (HR 4.22, 95% CI 1.30–13.7). Conclusion. Both SR and CR are associated with an inferior graft survival in recipients on RSW

    Increasing medical student interest in nephrology.

    BACKGROUND: Interest in nephrology careers is declining, possibly due to perceptions of the field and/or training aspects. Understanding practices of medical schools successfully instilling nephrology interest could inform efforts to attract leading candidates to the specialty. METHODS: The American Society of Nephrology Workforce Committee\u27s Best Practices Project was one of several initiatives to increase nephrology career interest. Board-certified nephrologists graduating medical school between 2002 and 2009 were identified in the American Medical Association Masterfile and their medical schools ranked by production. Renal educators from the top 10 producing institutions participated in directed focus groups inquiring about key factors in creating nephrology career interest, including aspects of their renal courses, clinical rotations, research activities, and faculty interactions. Thematic content analysis of the transcripts (with inductive reasoning implementing grounded theory) was performed to identify factors contributing to their programs\u27 success. RESULTS: The 10 schools identified were geographically representative, with similar proportions of graduates choosing internal medicine (mean 26%) as the national graduating class (26% in the 2017 residency Match). Eighteen educators from 9 of these 10 institutions participated. Four major themes were identified contributing to these schools\u27 success: (1) nephrology faculty interaction with medical students; (2) clinical exposure to nephrology and clinical relevance of renal pathophysiology materials; (3) use of novel educational modalities; and (4) exposure, in particular early exposure, to the breadth of nephrology practice. CONCLUSION: Early and consistent exposure to a range of clinical nephrology experiences and nephrology faculty contact with medical students are important to help generate interest in the specialty

    Background and objective African-Americans and Hispanic-Americans with lupus are the two most common minority groups who receive kidney transplants in the USA. It is unknown if African-Americans and Hispanic-Americans with lupus have similar outcomes after kidney transplantation. In this study, we assessed whether African-Americans compared to Hispanic-Americans have worse kidney allograft survival after risk factors of rejection and other prognostic factors were matched between both groups. Methods Out of 1816 African-Americans and 901 Hispanic-Americans with lupus, who received kidney transplants between 1987 and 2006 and had complete records in the UNOS program, 478 pairs were matched in 16 baseline predictors and follow-up time employing a predicted probability of group membership. The primary outcome was kidney allograft survival. Main secondary outcomes were rejection, allograft failure attributed to rejection, and mortality. Results Matched pairs were predominantly women (81%) with the mean age of 36 years. 96% were on dialysis before transplantation. 89% of recipients received kidneys from deceased donors and 15.5% from expanded criteria donors. 12% of recipients had zero HLA mismatch. African-Americans compared to Hispanic-Americans had lower cumulative allograft survival during 12-year follow-up ( p < 0.001). African-Americans compared to Hispanic-Americans had higher rates of rejection (10.4 vs 6.73 events/100 patients-years; p = 0.0002) and allograft failure attributed to rejection (6.31 vs 3.99; p = 0.0023). However, African-Americans and Hispanic-Americans had similar mortality rates (2.71 vs 2.31; p = 0.4269). Conclusions African-Americans compared to Hispanic-Americans with lupus had lower kidney allograft survival when recognized risk factors of rejection were matched between groups
