Abstract
Kidney dysfunction is common among liver transplant candidates with decompensated cirrhosis and has a major impact on pre- and post-liver transplant survival. Updated definitions of acute kidney injury and criteria for the diagnosis of hepatorenal syndrome allow for early recognition and intervention, including early initiation of vasoconstrictor therapy for hepatorenal syndrome. The rise of the metabolic syndrome and nonalcoholic fatty liver disease as a cause of cirrhosis has coincided with an increase in intrinsic chronic kidney disease recognized in transplant candidates and recipients. Ultimately, the ability to accurately assess kidney function and associated risk is essential to decision-making in the context of transplantation, including selection of candidates for simultaneous liver and kidney transplantation.

MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58060821. [PMID: 35744084 PMCID: PMC9227373 DOI: 10.3390/medicina58060821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 06/07/2022] [Accepted: 06/13/2022] [Indexed: 11/27/2022]
Abstract
Background and Objectives: Early allograft dysfunction (EAD) is considered a surrogate marker for adverse post-liver transplant (LT) outcomes. With the increasing use of nonconventional donors, EAD has become a more frequent occurrence. Given this background, we aimed to assess the prevalence and impact of EAD in an updated cohort inclusive of both conventional and nonconventional liver allografts. Materials and Methods: Perioperative and one-year outcomes were assessed for a total of 611 LT recipients with and without EAD from Mayo Clinic Arizona. EAD was defined as the presence of one or more of the following: bilirubin > 10 mg/dL on day 7, INR > 1.6 on day 7, or ALT and/or AST > 2000 IU/L within the first 7 days of LT. Results: Within this cohort, 31.8% of grafts (n = 194) came from donation after circulatory death (DCD) donors, 17.7% (n = 108) were nationally shared, 16.4% (n = 100) were allocated as post-cross clamp, and 8.7% contained moderate steatosis. EAD was observed in 52.2% (n = 321) of grafts in the study cohort (79% in DCD grafts and 40% in DBD grafts). EAD grafts had higher donor risk index (DRI) scores (1.9 vs. 1.6, p < 0.0001), were more likely to come from DCD donors (48% vs. 13.8%, p < 0.0001), were regionally allocated (p = 0.003), and had higher cold ischemia times (median 6.0 vs. 5.5 h, p = 0.001). Primary nonfunction events were rare in both groups (1.3% vs. 0.3%, p = 0.22). Post-LT acute kidney injury occurred at a similar frequency in recipients with and without EAD (43.6% vs. 30.3%, p = 0.41), and there were no differences in ICU (median 2 vs. 1 day, p = 0.60) or hospital (6 vs. 5 days, p = 0.24) length of stay. For DCD grafts, the rate of ischemic cholangiopathy was similar in the two groups (14.9% EAD vs. 17.5% no EAD, p = 0.69). One-year patient survival for grafts with and without EAD was 96.0% and 94.1% (HR 1.2, 95% CI 0.7−1.8; p = 0.54); one-year graft survival was 92.5% and 92.1% (HR 1.0, 95% CI 0.7−1.5; p = 0.88). Conclusions: In this cohort, EAD occurred in 52% of grafts. The occurrence of EAD, however, did not portend inferior outcomes. Compared to those without EAD, recipients with EAD had similar post-operative outcomes, as well as one-year patient and graft survival. EAD should be managed supportively and should not be viewed as a deterrent to utilization of non-ideal grafts.

Analysis of Prognostic Factors for Patients Undergoing Renal Replacement Therapy With Acute Kidney Injury Prior to Living Donor Liver Transplantation. Transplant Proc 2022; 54:380-385. [PMID: 35042598 DOI: 10.1016/j.transproceed.2021.10.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Accepted: 10/28/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Acute kidney injury (AKI) is a common complication in patients undergoing liver transplantation (LT) for end-stage liver disease (ESLD), and renal replacement therapy (RRT) is required in many cases. This study was performed to identify the prognostic factors for patients undergoing RRT owing to AKI before living donor liver transplantation (LDLT). MATERIALS AND METHODS From January 2010 to December 2018, LDLT was performed in 464 adult patients in our center. We reviewed 33 patients who underwent RRT before LDLT among 464 consecutive cases. Patients who continued to RRT after LDLT or who underwent subsequent kidney transplantation were considered to have not recovered from renal impairment. RESULTS Among 33 patients, there were 23 patients in the recovery group and 10 patients in the nonrecovery group. The preoperative duration of RRT was shorter in the recovery group, but it was not statistically significant. In the nonrecovery group, diabetes mellitus was found to have a higher prevalence and ischemic time was longer. Other perioperative factors were not significantly different between the 2 groups. After LDLT, the peak total bilirubin level was higher, and the intensive care unit stay was longer in the nonrecovery group. The overall survival rate was higher in the recovery group. CONCLUSIONS Liver transplant recipients who maintain RRT after LDLT have poor outcome. It is necessary to know the risk factors and manage them well, perioperatively.

Post-Liver Transplant Early Allograft Dysfunction Modifies the Effect of Pre-Liver Transplant Renal Dysfunction on Post-Liver Transplant Survival. Liver Transpl 2021; 27:1291-1301. [PMID: 33687745 DOI: 10.1002/lt.26047] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 02/13/2021] [Accepted: 03/01/2021] [Indexed: 01/13/2023]
Abstract
Pre-liver transplantation (LT) renal dysfunction is associated with poor post-LT survival. We studied whether early allograft dysfunction (EAD) modifies this association. Data on 2,856 primary LT recipients who received a transplant between 1998 and 2018 were retrospectively reviewed. Patients who died within the first post-LT week or received multiorgan transplants and previous LT recipients were excluded. EAD was defined as (1) total bilirubin ≥ 10 mg/dL on postoperative day (POD) 7, (2) international normalized ratio ≥1.6 on POD 7, and/or (3) alanine aminotransferase or aspartate aminotransferase ≥2000 IU/mL in the first postoperative week. Pre-LT renal dysfunction was defined as serum creatinine >1.5 mg/dL or on renal replacement therapy at LT. Patients were divided into 4 groups according to pre-LT renal dysfunction and post-LT EAD development. Recipients who had both pre-LT renal dysfunction and post-LT EAD had the worst unadjusted 1-year, 3-year, and 5-year post-LT patient and graft survival, whereas patients who had neither renal dysfunction nor EAD had the best survival (P < 0.001). After adjusting for multiple factors, the risk of death was significantly higher only in those with both pre-LT renal dysfunction and post-LT EAD (adjusted hazard ratio [aHR], 2.19; 95% confidence interval [CI], 1.58-3.03; P < 0.001), whereas those with renal dysfunction and no EAD had a comparable risk of death to those with normal kidney function at LT (aHR, 1.12; 95% CI, 0.86-1.45; P = 0.41). Results remained unchanged when pre-LT renal dysfunction was redefined using different glomerular filtration rate cutoffs. Pre-LT renal dysfunction negatively impacts post-LT survival only in patients who develop EAD. Livers at higher risk of post-LT EAD should be used with caution in recipients with pre-LT renal dysfunction.

Abstract
Background Liver transplantation (LT) is an effective option for hepatocellular carcinoma (HCC) and end-stage liver cirrhosis. However, organ shortage and tumor recurrence are the main obstacles limiting its popularization and application in HCC patients. Testing for circulating tumor cells (CTCs) would be a valuable strategy to predict the recurrence and metastasis of HCC after LT. Various CTCs detection methods have different advantages and disadvantages. This study aims to investigate the predictive value of testing for CTCs based on immunofluorescence in situ hybridization of peripheral blood cells in patients with HCC after LT. Methods A total of 50 patients who received testing for CTCs and then underwent LT were enrolled in this study. Negative enrichment and immunofluorescence in situ hybridization (imFISH) methods were introduced to detect CTCs. Results Twenty-six (52%) patients were CTC-positive, and 24 (48%) patients were CTC-negative. The results showed that CTCs result was correlated with tumor size (ꭓ2=5.773, P=0.016), AFP level (ꭓ2=5.454, P=0.020), tumor grade (ꭓ2=6.478, P=0.039) and Recurrence(ꭓ2=6.211, P=0.013).Twelve patients had recurrence after LT within one year. The results showed that the CTCs result (P=0.034) was the only independent factor impacting long-term survival. The 1-year disease-free survival rates of CTC-negative and CTC-positive patients were 91.6% and 61.5%, respectively (P=0.020). The 1-year overall survival of CTC-positive patients and CTC-negative was 88.5% and 91.7%, respectively (P=0.751). Conclusions CTCs result was closely related to the early recurrence of patients with HCC after LT. CTC-positive patients had a worse prognosis after LT than the CTC-negative group.

Abstract
Renal dysfunction is common in liver transplantation (LT) candidates, but differentiating between reversible and irreversible renal injury can be difficult. Kidney biopsy might be helpful in differentiating reversible from irreversible renal injury, but it is associated with significant complications. We aimed to identify pre-LT predictors of potentially reversible renal injury using histological information obtained on pre-LT renal biopsy. Data on 128 LT candidates who underwent pre-LT kidney biopsy were retrospectively collected and correlated with renal histological findings. Indications for kidney biopsy were iothalamate glomerular filtration rate (iGFR) ≤40 mL/minute, proteinuria >500 mg/day, and/or hematuria. According to the biopsy diagnosis, patients were grouped into the following categories: normal (n = 13); acute tubular necrosis (ATN; n = 25); membranoproliferative glomerulonephritis (n = 19); minimal histological changes (n = 24); and advanced interstitial fibrosis (IF) and glomerulosclerosis (GS) (n = 47). Compared with patients having advanced IF/GS, patients with normal biopsies and those with ATN had lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) and higher international normalized ratio and total bilirubin levels (<0.05 for all). Both SBP and DBP directly correlated with the degree of IF and GS (R = 0.3, P ≤ 0.02 for all). SBP ≤90 mm Hg was 100% sensitive and 98% specific in correlating with normal biopsies or ATN, whereas SBP ≥140 mm Hg was 22% sensitive and 90% specific in correlating with advanced IF/GS. Model for End-Stage Liver Disease score, serum creatinine, iGFR, urinary sodium excretion, and renal size did not correlate with biopsy diagnosis or degree of IF or GS. In conclusion, SBP at the time of LT evaluation correlates with renal histology, and it should be included along with other clinical and laboratory markers in the decision-making process to list patients with renal dysfunction for LT alone versus simultaneous liver-kidney transplantation.
