Outcome after liver transplantation in elderly recipients (>65 years) - A single-center retrospective analysis

Outcome of liver transplantation in elderly patients: an Italian multicenter case-control study

Despite the controversial results of liver transplantation (LT) in elderly recipients, the proportion of patients continues to increase. This study investigated the outcome of LT in elderly patients (≥ 65 years) in an Italian, multicenter cohort. Between January 2014 and December 2019, 693 eligible patients were transplanted, and two groups were compared: recipients ≥ 65 years (n = 174, 25.1%) versus 50-59 years (n = 519, 74.9%). Confounders were balanced using a stabilized inverse probability therapy weighting (IPTW). Elderly patients showed more frequent early allograft dysfunction (23.9 versus 16.8%, p = 0.04). Control patients had longer posttransplant hospital stays (median: 14 versus 13 days; p = 0.02), while no difference was observed for posttransplant complications (p = 0.20). At multivariable analysis, recipient age ≥ 65 years was an independent risk factor for patient death (HR  1.76; p = 0.002) and graft loss (HR  1.63; p = 0.005). The 3-month, 1-year, and 5-year patient survival rates were 82.6, 79.8, and 66.4% versus 91.1, 88.5, and 82.0% in the elderly and control group, respectively (log-rank p = 0.001). The 3-month, 1-year, and 5-year graft survival rates were 81.5, 78.7, and 66.0% versus 90.2, 87.2, and 79.9% in the elderly and control group, respectively (log-rank p = 0.003). Elderly patients with CIT > 420 min showed 3-month, 1-year, and 5-year patient survival rates of 75.7%, 72.8%, and 58.5% versus 90.4%, 86.5%, and 79.4% for controls (log-rank p = 0.001). LT in elderly (≥ 65 years) recipients provides favorable results, but inferior to those achieved in younger patients (50-59), especially when CIT > 7 h. Containment of cold ischemia time seems pivotal for favorable outcomes in this class of patients.

Effect of Age on Liver Transplantation Recipient Outcomes: Two Centers' Experience

BACKGROUND

Liver diseases epidemiology has changed with advances in perioperative care. Transplantation at large centers is favorable among older and younger recipients. Local limitations on transplantation for recipients older than 65 years were cancelled in 2014. This study evaluates the effects of age on the transplantation outcome of Israeli patients in the era after removal of the limitations on recipient age.

METHODS

This retrospective analysis examined prospective data on patients older than 18 years who underwent liver or liver-kidney transplantation between 2014 and 2019 at 2 transplantation centers. Patients were divided into 4 age groups (group 1: ≤59 years; group 2: 60-64 years; group 3: 65-69 years; and group 4: ≥70 years). Each group's associations of pretransplantation factors with outcome and survival were examined.

RESULTS

Two hundred sixty-one recipients underwent 269 transplantations (mean age: 53 ± 12.61 y). There were 181 male (67.8%) and 88 female recipients (67.28%). Overall, 207 patients (79.6%) survived ≥12 months. One-year survival rates were 82.9%, 73.2%, 71.4%, and 93.8% for groups 1 to 4, respectively (not statistically significant; P = .11). One-year graft survival was similar between groups. More patients with chronic obstructive pulmonary disease, diabetes mellitus, or ischemic heart disease tended to survive <12 months. Cardiovascular complication was more common in older groups and affected survival.

CONCLUSION

Patient age alone should not be used to deny access to transplantation, which could benefit older nonfrail individuals. However, risk factors such as male sex, chronic obstructive pulmonary disease, ischemic heart disease, diabetes mellitus, and concomitant kidney-liver transplantation should be carefully considered.

[Liver transplantation in aged patients]

Due to the demographic changes and the increasing incidence of chronic, especially nutritively toxic liver diseases, the number of patients over 65 years of age with indications for liver transplantation is rising considerably. Patient age alone is not a contraindication for organ transplantation; however, in order to ensure the postoperative outcome, a structured interdisciplinary assessment is necessary, especially in older potential organ recipients. With knowledge of comorbidities, individualized prehabilitation enables the perioperative risk to be minimized. The postoperative morbidity in aged patients appears to be comparable to that of younger patients, especially after careful evaluation. Overall, there is a clear survival advantage compared with the best conservative treatment for liver disease. In addition to the perioperative procedure, differences in follow-up care and long-term outcome should also be considered. In this context, predominantly the pharmacological peculiarities, such as polypharmacy and the mutual influence of immunosuppression and comorbidities, have to be taken into account. In addition to old organ recipients, livers from old donors (so-called marginal organs) increasingly play a crucial role in transplantation medicine due to the organ shortage. These are more susceptible to ischemia reperfusion injury and thus put the recipient at a higher risk for delayed or lack of organ function recovery. New ethical issues are raised by the increasing age of donors and recipients, complicating decision making about organ acceptance or rejection for the transplantation physician.

Septuagenarian Donors and Recipients in Deceased Donor Liver Transplantation: A Brazilian Single Center Experience and Literature Review

BACKGROUND

The number of elderly patients who have end-stage liver disease and require liver transplantation has dramatically increased. On the other hand, liver grafts from elderly donors have been offered more frequently for transplantation. The present study aims to analyze the results of liver transplants performed with donors and recipients aged ≥70 years.

METHODS

We performed a single-center retrospective study of deceased donors liver transplants that involved recipients aged ≥7070 years or recipients who received grafts from donors aged ≥70 years from 2011 to 2021. A literature review on the results of liver transplantation in elderly recipients was also performed.

RESULTS

Thirty septuagenarian recipients were included; their overall 1- and 5-years survival was 80% and 76.6%, respectively. The prevalence of recipients aged ≥70 years in our department was 2.65%. Twenty recipients received grafts form septuagenarian donors; their overall 1- and 5-years survival was 75%. The prevalence of donors aged ≥70 years in our department was 1%. In the literature review, 17 articles were analyzed. The 5-years survival of recipients aged ≥70 years ranged from 47.1% to 78.5%.

CONCLUSIONS

Septuagenarian recipients and patients who received grafts from elderly brain-dead donors present adequate overall survival after liver transplantation. Optimized donor-recipient matching is paramount for achieving good outcomes. The combination of high-risk donors with septuagenarian recipients should be avoided as well as using grafts of elderly donors that present others risk factors. Thus, the age of the donor or recipient alone cannot be considered an absolute contraindication for liver transplantation.

Clinical Outcomes of Liver Transplantation for Patients Over 60 Years Old: A Single-Center Experience

OBJECTIVES

Although advanced age is no longer considered an absolute contraindication for liver transplant, transplant in elderly patients with comorbid diseases remains debatable because of high risks with surgery. Here, we report patient outcomes in this population.

MATERIALS AND METHODS

We retrospectively reviewed medical records of 276 liver transplant recipients, grouped by age. Group 1 (≤59 years old) consisted of 247 recipients, and group 2 (≥60 years old) consisted of 29 recipients. Reviewed data included age, sex, cause of liver disease, presence of hepatocellular carcinoma, Child-Pugh and Model for End-Stage Liver Disease scores, survival, and posttransplant complications.

RESULTS

In both groups, most patients (n = 108) required liver transplant for hepatitis B virus. Mean age was 40 ± 12.3 and 63 ± 2.3 years in groups 1 and 2, respectively, with more men than women in both group 1 (71.7% vs 28.3%) and group 2 (75.9% vs 24.1%). No significant differences were shown between groups for patient characteristics, except group 1 had significantly higher Model for End-Stage Liver Disease score. Group 1 mean survival time was 10.2 ± 0.6 years, with patient survival rates at 1, 5, 10, and 15 years of 65.5%, 53%, 46.3%, and 40%, respectively. In group 2, respective results were 10.6 ± 1.3 years and 75.9%, 68.6%, 61%, and 48.8% (no significant difference vs group 1).

CONCLUSIONS

Liver transplant recipients >60 years of age had survival rates, acute rejection rates, and complications similar to younger recipients. Liver transplant should not be withheld from older recipients on the basis of age alone. However, comprehensive screening for comorbidities should be performed.

Transplant of Elderly Patients: Is There an Upper Age Cutoff?

Increased life expectancy and advances in the care of chronic liver disease has increased the number of elderly patients needing liver transplant. Organ donation policies prioritize transplant to the sickest. There is an ongoing debate with regard to balancing the principles of equity and utility. Several hospitals have adopted center-specific policies and there has been an increased trend of transplant in elderly patients since 2002. Appropriate patient selection and long-term outcomes in the setting of limited organ availability pose several challenges. This article reviews the data and discusses the pros and cons of transplants in the elderly.

Living Donor Liver Transplant in Patients Aged 60 Years or Older: Experience from a Large Volume Centre in India

BACKGROUND

With ageing population and higher prevalence of nonalcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC) in older patients, more and more living donor liver transplants (LDLTs) are being considered in this group of patients as eligibility for deceased donor liver transplant is restricted to those aged 65 years and younger. However, the short- and long-term outcomes of this group have not been reported from India, which does not have a robust national health scheme. The aim of this study was to provide guidelines for transplant in this group.

METHODS

All patients aged 60 years and older (group 1) who underwent LDLT in our centre between January 2006 and December 2017 were studied. A propensity score-matched group in 1:2 ratio was created with comparable sex and Model for End-Stage Liver Disease score (group 2). The 2 groups were compared for duration of hospital stay, surgical complications, hospital mortality and 1-, 3- and 5-year survival.

RESULTS

Group 1 consisted of 207 patients, and group 2 had 414 patients. The number of patients in group 1 gradually increased with time from 4 in 2006 to 33 in 2017 accounting for 15% of total cases. Group 1 had more patients with viral hepatitis, NASH and HCC, and they had a higher 30-day mortality due to cardiorespiratory complications. Although 1- and 3-year survival was similar, the 5-year survival was significantly lower in group 1.

CONCLUSION

Five-year survival was lower in the elderly group due to cardiorespiratory complications and recurrence of HCC. Outcomes in the elderly group can be improved with better patient selection and preventing HCC recurrence.

Impact of Recipient Age in Combined Liver-Kidney Transplantation: Caution Is Needed for Patients ≥70 Years

Elderly recipients (≥70 y) account for 2.6% of all liver transplants (LTs) in the United States and have similar outcomes as younger recipients. Although the rate of elderly recipients in combined liver-kidney transplant (CLKT) is similar, limited data are available on how elderly recipients perform after CLKT.

METHODS

We have previously shown excellent outcomes in CLKT using delayed kidney transplant (Indiana) Approach (mean kidney cold ischemia time = 53 ± 14 h). Between 2007 and 2018, 98 CLKTs were performed using the Indiana Approach at Indiana University (IU) and the data were retrospectively analyzed. Recipients were subgrouped based on their age: 18-45 (n = 16), 46-59 (n = 34), 60-69 (n = 40), and ≥70 years (n = 8).

RESULTS

Overall, more elderly patients received LT at IU (5.2%) when compared nationally (2.6%). The rate of elderly recipients in CLKT at IU was 8.2% (versus 2% Scientific Registry of Transplant Recipient). Recipient and donor characteristics were comparable between all age groups except recipient age and duration of dialysis. Patient survival at 1 and 3 years was similar among younger age groups, whereas patient survival was significantly lower in elderly recipients at 1 (60%) and 3 years (40%) (P = 0.0077). Control analyses (replicating Scientific Registry of Transplant Recipient's survival stratification: 18-45, 46-64, ≥65 y) showed similar patient survival in all age groups.

CONCLUSIONS

Although LT can be safely performed in elderly recipients, extreme caution is needed in CLKT due to the magnitude of operation.

Survival Outcomes After Liver Transplantation in Elderly Patients: A Single-Center Retrospective Analysis

AIM

This study aims to evaluate survival rates in elderly patients after liver transplantation (LT) and to analyze the factors associated with mortality.

PATIENTS AND METHODS

Our study includes 535 patients over the age of 18 who had undergone LT in our clinic between June 2004 and January 2018. Data were collected prospectively and scanned retrospectively. Data concerning the patients' age, sex, LT indication, Child-Turcotte-Pugh score, Model for End-Stage Liver Disease score, presence of hepatocellular cancer (HCC), coexisting disease, LT types, and post-transplant survival were investigated. The patients were grouped under 2 categories (18-59 years of age and 60 years of age and over) and were compared in terms of their characteristics. In patients aged 60 and over, the causes of mortality and related factors were investigated.

RESULTS

The study included 535 patients, 458 (85.6%) of whom were between 18 and 59 years of age and 77 (14.4%) were over 60 years of age. The median follow-up period was 86.7 (1 to 247) months. The elderly group's survival rate was significantly lower than that of the younger group (P = .002). In elderly patients, survival rates of 1, 3, 5, and 10 years were 67.4%, 56.4%, 53.8%, and 46.1%, respectively.

CONCLUSION

In elderly patients, factors that increase post-LT mortality require thorough consideration. Equally important is the physiological status of the candidates for transplantation. Correct patient selection in the preoperative stage and good postoperative care can provide successful survival results in elderly patients.
