RESUMO

During the early wave of the COVID-19 pandemic, the Scientific Registry of Transplant Recipients (SRTR) designated a "black out" period between March 12, 2020, and June 12, 2020, for transplant outcomes reporting. We discuss the implications and potential bias it has introduced as it may selectively favor the outcomes for certain regions and harm other regions due to varied effects of different waves of COVID-19 infections across the United States.

RESUMO

The number of patients presenting with cirrhosis with kidney injury and the potential need for SLKT is increasing. In 2017, standardized criteria were implemented to identify candidates for SLKT as well as criteria for prioritizing LTA recipients for kidney transplant if they developed kidney failure, which is referred to as the 'safety net rule.' Goal of the safety net rule is to provide a pathway that provides increased priority to LTA recipients with renal failure who may have previously undergone SLKT. This article reviews the pros and cons of the safety net rule for liver transplant recipients who develop ESRD.

RESUMO

Donor-derived (DD) herpes simplex virus (HSV) hepatitis in solid organ transplant (SOT) recipients is extremely uncommon but carries a high mortality rate. The diagnosis is challenging due to the non-specific presentation and lack of clinical suspicion. We report a case of DDHSV hepatitis in a HSV2 pre-transplant seronegative kidney recipient who received the organ from a HSV2 seropositive donor. The case is highlighted by a few unusual features, namely severe thrombocytopenia and the development of cutaneous, oral and esophageal HSV lesions several weeks after symptom onset while recovering on appropriate treatment. A review of nine proven and probable DDHSV hepatitis cases (including eight previously published ones) showed that fever is a common presenting feature while gastrointestinal symptoms and cutaneous manifestations are uncommon. The symptoms almost always occurred within 2 weeks of transplant. Six out of the nine DDHSV hepatitis patients, including five patients who were on appropriate treatment, died within a month after transplant.

RESUMO

Health care has shifted to placing priority on quality and value instead of volume. Liver transplantation uses substantial resources and is associated with high readmission rates. Our goal was to determine if a protocol designed to reduce readmission after liver transplant was effective. We conducted a prospective study of a protocol designed to reduce readmission rates after liver transplantation by expanding outpatient services and alternatives to readmission. The 30-day readmission rate 1 year after implementing the protocol was compared to the 30-day rate for 2 years prior to implementation. Multivariate analysis was used to control for potential confounding factors. Over the study period, 167 adult primary liver transplants were performed with a mean biological Model for End-Stage Liver Disease score of 21 ± 8. Fifty-seven (34%) patients were readmitted. The most common reason for readmission was biliary complications (n = 13). The 30-day readmission rate decreased from 40% before implementing the protocol to 20% after implementation (P = 0.02). In multivariate analysis, the protocol remained associated with readmission (odds ratio, 0.39; 95% confidence interval, 0.16-0.92; P = 0.03). The mean length of stay after transplant was 13 ± 12 days preprotocol and 9 ± 5 days postprotocol (P = 0.09). Alternatives to readmission, including hospital lodging and observation status, were main factors in reducing readmission rates. If the most recent definitions of inpatient admission and observation status were applied over the entire study period, then the readmission rates preprotocol and postprotocol were 31% and 20% indicating that the revised definition of observation status accounted for 45% of the reduction in the readmission rate. Readmission after liver transplantation can be reduced without increasing length of stay by implementing a specifically designed protocol that expands outpatient services and alternatives to inpatient admission.

RESUMO

BACKGROUND: Post-transplant hepatitis C is a major challenge after liver transplantation (LT). Antiviral therapy is associated with lower efficacy in the post-transplant setting. AIMS: The purpose of this study was to determine the safety and effect of intravenous interferon (IFN) during the anhepatic phase of LT on hepatitis C viral load. METHODS: Fifteen consecutive subjects undergoing liver transplant for hepatitis C cirrhosis were enrolled in the study, ten of which received study drug and five subjects served as controls. Cases received weight-based ribavirin and subcutaneous IFN at time of incision followed by intravenous IFN at the start of the anhepatic phase. Adverse events and viral levels were recorded. Repeated measures ANOVA was employed to test for differences over time, between the groups, and time by group interaction. RESULTS: All subjects had genotype 1 virus. Hepatitis C viral load was lower at week 4 in cases compared to controls (769,004 ± 924,082 IU/ml and 2,329,896 ± 3,731,749 IU/ml, respectively), but did not reach statistical significance (p = 0.50). Three subjects developed adverse events related to IFN including pulmonary edema, rejection, and neutropenia. CONCLUSIONS: Intravenous IFN administered during the anhepatic phase of liver transplant did not prevent graft reinfection and was associated with manageable adverse events. This regimen could be further studied if direct acting antiviral agents alone are insufficient for treating post-transplant hepatitis C.

RESUMO

OBJECTIVES: The Association of Program Directors in Surgery/American College of Surgeons national skills curriculum provides residency programs with a great educational tool for their residents. Our objective was to assess the feasibility, value, and cost required to administer a procedural workshop for general surgery residents based on phase II of the national skills curriculum. DESIGN, SETTING, AND PARTICIPANTS: Surgery faculty instructed residents on a variety of level-appropriate surgical procedures during a procedural workshop using 4 training models (2 cadaver torsos and 2 pigs). The educational value of the workshop, the quality of teaching, the instruction and feedback received, and the training models used were evaluated by participants on a 10-point Likert scale. Resident performance and workshop cost were also assessed. RESULTS: Seven faculty instructed 16 residents (postgraduate year 1-4) on 23 surgical procedures (median 4 procedures per resident). Participants rated the overall value of the workshop as 8 (range, 7-10). Residents rated the quality of teaching as 9 (range, 6-10) and the quality of instruction and feedback received as 8.5 (range, 6-10). Overall resident performance was rated as 8 (range, 5-10) by faculty. The factors most positively impacting the quality of the workshop were reported to be the close interaction between residents and faculty, the training models, and the protected time. Sixty-eight percent of participants indicated that both cadaver and pig models were necessary for this course, and all participants believed that such workshops should be part of the general surgery curriculum. Overall cost reached just under $10,000 excluding supplies and faculty time. CONCLUSIONS: The feasibility of a cadaveric and animal-based procedural workshop for surgery residents based on phase II of the national skills curriculum was demonstrated. While very resource-intensive and costly, the educational value of this workshop was rated highly by residents and faculty because of their close interaction in a relaxed environment. Such workshops should be incorporated into the surgical curriculum.

RESUMO

BACKGROUND: Calcineurin inhibitors (CNIs) have been the mainstay of immunosuppressive protocols in kidney transplantation over the past 20 years. However, in some recipients, the adverse effects of CNIs contribute to chronic allograft nephropathy and death with function--the two leading causes of late graft loss. Other recipients maintain stable graft function. METHODS: We studied the impact of continuing CNI-based immunosuppression in the second decade after kidney transplantation. From 1984 through 1996, a total of 1,263 patients underwent a primary kidney transplant at the University of Minnesota and received cyclosporine-based immunosuppression. Antibody induction was used only in deceased donor recipients. RESULTS: The actuarial 20-year patient survival rate was 38%; graft survival, 30%; and death-censored graft survival, 60%. The annual mean serum creatinine level for recipients whose grafts survived > or =1 year remained stable, although recipients with a history of > or =1 acute rejection episode had a higher serum creatinine level vs. recipients who were rejection-free. The annual mean calculated creatinine clearance was also stable over time. In addition, for recipients who were acute rejection-free, chronic allograft nephropathy/chronic rejection was only responsible for 9% of graft losses. CONCLUSIONS: Our study suggests that some kidney transplant recipients tolerate long-term CNI-based immunosuppression with stable creatinine levels. Identifying certain recipients' predisposition to CNI toxicity and individualizing immunosuppressive therapy may be important in order to improve long-term kidney function, while simultaneously preserving low short-term acute rejection rates.

RESUMO

BACKGROUND: The risk of recurrence of glomerulonephritis in kidney transplant recipients on a steroid-free maintenance immunosuppression protocol is unknown. METHODS: We studied the 4-year graft and patient survival in 105 adult kidney transplant recipients who received their transplant for glomerulonephritis (GN) and were treated with a protocol incorporating rapid discontinuation of prednisone for 5 days (group 1). We compared these outcomes to two control groups; 439 concurrent recipients who received a transplant for causes other than GN (group 2) and to 260 kidney transplant recipients who received an allograft for GN between 1994 and 1999 and were maintained on a steroid-based immunosuppressive protocol (group 3). RESULTS: The 4-year graft and patient survival were similar in the three groups. Acute rejection-free survival was also similar. Serial annual serum creatinine and estimated GFR were also comparable amongst the three groups. Two grafts were lost in group 1 from biopsy-proven recurrent GN and eight other subjects had evidence of histological recurrence at 11.2+/-11.9 months. Seven grafts were lost for recurrent disease in group 3 and 15 others had evidence of histological recurrence at 29.1+/-32.6 months. The mean time to graft loss from recurrence was 52+/-22 months. CONCLUSION: A regimen that utilizes rapid discontinuation of steroids conveys no added risk of graft loss from recurrent GN in the short term but longer follow-up is needed. A consideration should be made to discontinue corticosteroids in the potential recipients who are on them at the time of transplantation.

RESUMO

Renal autotransplantation is an acceptable treatment for a variety of renal pathology. Indications for autotransplantation include renal artery diseases, loin pain hematuria syndrome, repair of ureteral pathology, ex vivo tumor resection, and repair of traumatic injury. Long-term results confirm that autotransplantation is a safe and effective procedure. Renal allograft autotransplantation has also been described for repair of vascular disease, and relocation of an allograft. We describe the first case, to our knowledge of an emergent autotransplant of a renal allograft. The patient had undergone a simultaneous kidney-pancreas transplant 7 yr prior. During attempted stenting of a common iliac artery occlusion, the stent migrated, thus jeopardizing the renal allograft. The patient was taken emergently to the operating room for open repair. This included autotransplantation of the entire kidney. The patient recovered to baseline renal function. This article reviews the indications for renal autotransplantation and autotransplantation of a renal allograft. A case of emergent autotransplant of a renal allograft is described.

RESUMO

We compared three maintenance immunosuppressive regimens in a rapid discontinuation of prednisone protocol. From March 1, 2001, through December 31, 2003, 239 first and second kidney transplant recipients (166 LD; 73 DD) were randomized. All recipients were treated with Thymoglobulin; all received steroids intraoperatively and for 5 days postoperatively. Randomization was to cyclosporine-mycophenolate mofetil (n = 85); high-level tacrolimus (TAC) (8-12 ng/mL)-low-level sirolimus (SRL) (3-7 ng/mL) (n = 72); or low-level TAC (3-7 ng/mL)-high-level SRL (8-12 ng/mL) (n = 82). We found no difference at 24 months between groups in patient, graft, death-censored graft, or acute rejection-free graft survival, or in kidney function. Wound complications were more common in SRL-treated recipients (p = 0.02); we found no other differences between groups in complication rates. Our data suggest that excellent patient and graft survival and low rejection rates can be obtained using a variety of maintenance protocols without prednisone.
