The Impact

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.

The Impact

Background: Antiretroviral therapy (ART) poses challenging drug-drug interactions with immunosuppressant agents in transplant recipients.  We aimed to determine the impact of specific antiretroviral regimens in clinical outcomes of HIV+ kidney transplant recipients. Methods: A single-center, retrospective cohort study was conducted at a large academic center. Subjects included 58 HIV- to HIV+ adult, first-time kidney transplant patients. The main intervention was ART regimen used after transplantation.  The main outcomes assessed at one- and three-years were: patient survival, death-censored graft survival, and biopsy-proven acute rejection; we also assessed serious infections within the first six months post-transplant. Results: Patient and graft survival at three years were both 90% for the entire cohort. Patients receiving protease inhibitor (PI)-containing regimens had lower patient survival at one and three years than patients receiving PI-sparing regimens: 85% vs. 100% (p=0.06) and 82% vs. 100% (p=0.03), respectively. Patients who received PI-containing regimens had twelve times higher odds of death at 3 years compared to patients who were not exposed to PIs (odds ratio, 12.05; 95% confidence interval, 1.31-1602; p=0.02).  Three-year death-censored graft survival was lower in patients receiving PI vs. patients on PI-sparing regimens (82 vs 100%, p=0.03). Patients receiving integrase strand transfer inhibitors-containing regimens had higher 3-year graft survival. There were no differences in the incidence of acute rejection by ART regimen. Individuals receiving PIs had a higher incidence of serious infections compared to those on PI-sparing regimens (39 vs. 8%, p=0.01). Conclusions: PI-containing ART regimens are associated with adverse outcomes in HIV+ kidney transplant recipients.

Abstract Many studies have reported that protocol biopsy (PB) may help preserve kidney function in kidney transplant recipients. Early detection and treatment of subclinical rejection may reduce the incidence of chronic allograft nephropathy and graft failure. However, no consensus has been reached regarding PB effectiveness, timing, and policy. This study aimed to evaluate the protective role of routine PB performed 2 weeks and 1 year after kidney transplantation. We reviewed 854 kidney transplant recipients at the Samsung Medical Center between July 2007 and August 2017, with PBs planned at 2 weeks and 1 year after transplantation. We compared the trends in graft function, chronic kidney disease progression, new-onset chronic kidney disease, infection, and patient and graft survival between the 504 patients who underwent PB and 350 who did not undergo PB. The PB group was again divided into two groups: the single PB group (n = 207) and the double PB group (n = 297). In the PB group, the donors and recipients were significantly older and there was a greater presence of recipient diabetes mellitus and donor hypertension, donor-specific antigen, and a higher proportion of ABO-incompatible kidney transplantations. The PB group was significantly different from the no-PB group in terms of the trends in graft function (estimated glomerular filtration rate). The Kaplan-Meier curve showed that PB did not significantly improve graft survival or overall patient survival. However, in the multivariate Cox analysis, the double PB group had advantages in graft survival, chronic kidney disease progression, and new-onset chronic kidney disease. PB can play a protective role in the maintenance of kidney grafts in kidney transplant recipients.

The Impact

The risk of cancer increases after transplantation. However, the consensus on immunosuppression (IS) adjustment after diagnosis of malignancy is lacking. Our study aims to assess the impact of IS adjustment on mortality of post-kidney transplant patients and allograft outcomes. We retrospectively reviewed the data in our center of 110 subjects. Our results showed IS dose adjustment was not statistically associated with mortality risk (HR 1.94, 95%CI 0.85–4.41, p = 0.12), and chemotherapy was the only factor that was significantly related to mortality (HR 2.3, 95%CI 1.21–4.35, p = 0.01). IS reduction was not statistically associated with worsening graft function (OR 3.8, 95%CI 0.77–18.71, p = 0.10), nor with graft survival (SHR 4.46, 95%CI 0.58–34.48, p = 0.15) after variables adjustment. Creatinine at cancer diagnosis and history of rejection were both negatively associated with graft survival (SHR 1.72, 95%CI 1.28–2.30, p < 0.01 and SHR 3.44, 95%CI 1.25–9.49, p = 0.02). Reduction of both mycophenolate and calcineurin inhibitors was associated with worsening graft function and lower graft survival in subgroup analysis (OR 6.14, 95%CI 1.14–33.15, p = 0.04; HR 17.97, 95%CI 1.81–178.78, p = 0.01). In summary, cancer causes high mortality and morbidity in kidney transplant recipients; the importance of cancer screening should be emphasized.

The Impact

Abstract Background Several factors are important in order to predict the graft survival in kidney transplant recipients like the age of recipient, BMI, serum cratinine, and having history of dialysis. One factor that can have impact of transplant outcomes but not considered can be the age of donor and recipients. Patients and Methods The numbers of 1113 kidney transplant recipients were considered through a retrospective cohort study. Several factors were taken into the account of graft survival and outcomes like gender and age of donor and recipients in addition to common recipient factors like cratinine, eGFR, BMI, and positive history of dialysis. Results The most successful transplant based on donor-recipient gender was seen in male donor to male recipient and then male donor to female recipient. In female transplant recipient the level of serum creatinine, and eGFR, have dialysis history before transplant, and low donor hemoglobin level can be a good prognosis factor that should considered for kidney transplant survival. Conclusions Our result suggested that the gender match is suggested for kidney transplant. On some exceptional occasion just kidney of male donor to female recipient may be successful and it would be better to hesitate female donors to male recipients especially in aged patients with history of dialysis.

Gender Matching

Abstract Background: Several factors like age of recipient, BMI, serum cratinnine , and positive history of dialysis are important in predicting graft survival in kidney transplant recipients. One factor that can affect transplant outcomes and is usually ignored is the gender of donor and recipients. Methods: A total of 1113 kidney transplant recipients were studied in a retrospective cohort study. Several factors were taken into account for graft survival and outcomes like gender and age of donor and recipients in addition to common recipient factors like cratinnine , eGFR, BMI, and positive history of dialysis. Results: The most successful transplant based on donor-recipient gender was seen in male donor to male recipient and then male donor to female recipient. In female transplant recipients, level of serum cratinnine , and eGFR, positive dialysis history before transplant, and low donor hemoglobin level can be good prognostic factors recommended to be considered for kidney transplant survival. Conclusions: Our results suggested that gender matching for kidney transplant. Only on some exceptional occasions, male donor to female recipient kidney transplant may be successful and female donors to male recipients are not suggested, especially in aged patients with history of dialysis.
