Long-term donor quality of life after living donor liver transplantation in Japan

A systematic review of the factors significantly influencing the quality of life of living liver donors

Objectives

This systematic review aimed to synthesize the literature on factors influencing the quality of life in living liver donors post-donation and to provide a reference for developing targeted interventions in clinical practice.

Methods

A systematic search guided by the PRISMA 2020 approach was performed on specific databases: PubMed, EMBASE, CINHAL with full text, Web of Science, and ProQuest Dissertations & Theses databases. Peer-reviewed articles published in English from inception to October 2022 covering cross-sectional studies and longitudinal studies on factors affecting the quality of life of living liver donors after donation were included in this systematic review. The methodological quality of the studies was examined using a modified version of the National Institutes of Health Quality Assessment Tool.

Results

A total of 6,576 studies were retrieved, and 16 eligible studies were finally included. Four types of independent influencing factors: sociodemographic (gender, donor age, education, ethnicity, and marital status), donation-related (length of hospital stay and number of hospitalizations/hospital visits related to donation surgery, recipient outcome, time from donation, complications, donation decision, ambivalence about donating, donor-recipient relationship), health-related (body mass index and pre-donation physical symptoms), and psychosocial (pre-donation physical and mental score, household income, anxiety, depression), were extracted from the included studies. Several studies consistently identified old age, recipient death, recent donation, postoperative complications experienced by donors, and donor concerns about their well-being as negative influencing factors on physical function. Female donors, low education levels, longer hospital stays, and/or more hospital visits due to donation, poor recipient outcome, recent donation, pre-donation concerns regarding their well-being, and first-degree relative and spouse/partner donors were reported in several studies as negative predictors for psychological status. Factors affecting social function were considered by only two included articles.

Conclusions

The quality of life of living liver donors could be affected by both donation surgery and psychosocial factors. Based on the above-influencing factors, clinical nurses can develop targeted interventions to improve the quality of life of living liver donors.

Long-term risk of a fatty liver in liver donors

Aim

Approximately 30 years have passed since the first experience of living donor liver transplantation. The time to evaluate the long-term safety of living donors has been fulfilled. Meanwhile, nonalcoholic fatty liver disease is increasingly common and a critical problem. The aim of this study was to evaluate the safety of living donor, focusing on fatty liver postdonation hepatectomy.

Methods

Living donors (n = 212, 1997-2019) were evaluated by computed tomography (CT) at >1-year postdonation. A liver to spleen (L/S) ratio of <1.1 was defined as fatty liver.

Results

Among 212 living liver donors, 30 (14.2%) detected fatty liver at 5.3 ± 4.2 years postdonation. The cumulative incidence rates of fatty liver were 3.1%, 12.1%, 22.1%, and 27.7% at 2, 5, 10, and 15 years postdonation, respectively. Of 30 subjects who developed fatty liver, 18 (60%) displayed a severe steatosis (L/S ratio <0.9). Five (16.7%) had a prior history of excessive alcohol abuse. More than 30% developed metabolic syndrome including obesity, hyperlipidemia, and diabetes. Although six (20%) had a Fib-4 index of >1.3, which included a case with a Fib-4 index of >2.67, no significant increased Fib-4 index was observed in the subjects with fatty liver as compared to those without fatty liver (p = 0.66). The independent predictive risk factors for developing fatty liver were male sex, pediatric recipient, and higher body mass index (>25) at donation.

Conclusion

Living donors with risk factors for developing fatty liver should be carefully followed-up for the prevention and management of metabolic syndrome.

The effect of a web-based self-care instruction on symptom experience and quality of life in living liver donors: A randomized controlled trial

Objective

Living liver donors need help to manage symptom distress and improve their quality of life. This study aims to test the effectiveness of a web-based symptom self-care instruction on symptom experience and health-related quality of life of living liver donors.

Methods

This study was a randomized controlled trial. Participants were recruited from January 2019 to August 2020. Participants in the experimental group had access to a web-based symptom self-care instruction, which included text and video. The control group received routine care. The primary outcomes were symptom distress and quality of life.

Results

A total of 90 living liver donors recruited in this study were assigned randomly to the web group (n = 46) and control group (n = 44). The symptom distress was significantly negatively correlated with quality of life at each data collection time. There was an interaction effect with the participants in the web group experiencing more symptom distress at three months after surgery than the control group (B = 3.616, 95% CI: 7.163-3.990, p = 0.046). There was no significant effect on the quality of life.

Conclusion

Patients in the web-based self-care group had higher symptom distress than those in the control group three months after surgery, but there was no difference in quality of life. Future studies could add some interactive elements to the website and include a larger sample size.

Registration

This study was registered at the Chinese Clinical Trial Registry (ChiCTR1900020518).

Anxiety, pain intensity, and decision regret of living liver donors during postoperative period

AIM

The aim of this study was to explore and examine the relationship between anxiety, acute pain intensity, and decision regret of living liver donors in the postoperative stage.

METHODS

This is a prospective correlational study. Data were collected consecutively for one year (from September 2017 to September 2018) at a medical center in northern Taiwan. Information about anxiety and acute pain intensity was collected preoperatively and on postoperative day (POD) 3 and POD 7. Satisfaction with pain management and decision regret was inquired about on POD 7.

RESULTS

Data of 57 consecutive living liver donors (56.1 % male, mean age 34.12 ± 9.92 years) were analyzed. Living liver donors experienced moderate anxiety and acute pain levels in the postoperative period. The mean score of decision regret was 12.63 (range 0-60), indicating a low level of regret. The acute pain intensity decreased significantly between POD 3 and POD 7 (p < .001); however, the anxiety level slightly increased (p = .031). Older and married living liver donors had higher anxiety levels. The satisfaction level of pain management was negatively correlated with the POD 7 acute pain intensity (r = -0.26, p = .049) and decision regret (r = -0.37, p = .005), but it was positively correlated with POD 7 anxiety (r = 0.38, p = .004).

CONCLUSIONS

The postoperative period was hard for living liver donors as they would experience moderate acute pain and anxiety. Although the decision regret was low, the satisfaction level of pain management would negatively affect it. Therefore, the effectiveness of pain management and anxiety management should be continually ensured in the postoperative period.

Multi-center living liver donor quality of life survey up to 20 years after donor hepatectomy and association with surgical outcomes

BACKGROUND

We implemented a multicenter interview with the donors to investigate Quality of Life (QoL) up to 20 years following donation.

METHODS

Data were collected retrospectively. Complications were graded by Dindo-Clavien classification.

RESULTS

Median follow-up was 16.1 years. Out of 485 donors, 272 responded (56.1%). The majority (>90%) reported they are in excellent/good overall health and positive or no impact of donation on professional life. Length of stay (LOS) was associated with impact on professional life and return to baseline functionality (both p = 0.046). Major complication was not associated with current physical condition or return to baseline normalcy (p = 0.06). Seventy-five (27.5%) reported unsure or no to donate again. None of the parameters were associated with donation again response. Faster return to baseline functionality, and more positive impact on professional life were reported in the last decade, likely secondary to less complication rates (all p < 0.001).

CONCLUSION

This the longest follow up reports after living liver donation among German and Turkish populations. Although subject to recall bias, LOS was associated with negative impact on professional life and return to baseline functionality. Regret feelings were higher than literature. These long-term effects should be incorporated into donor discussions.

Does living liver donors' underestimation about surgical outcomes impact on their health-related quality of life after donation?: a descriptive cross-sectional study

Background

In South Korea, the number of living-donor liver transplantations in 2019 was 1,188. Living liver donors (LLDs) undergo surgery and the postoperative recovery process for altruistic purposes. This study explored LLDs’ unmet expectations about surgical outcomes and examined their impact on the donors’ health-related quality of life (HRQOL).

Methods

This descriptive cross-sectional study utilized a self-reported survey. Data were collected at a university hospital in Seoul, South Korea. Among the 535 LLDs who underwent surgery for donation between January 2011 and March 2021, 124 participated in this study. The Korean version of the 12-item Short Form Health Survey version 2 (SF-12v2) was used to measure the HRQOL of LLDs. Unmet expectations regarding surgical outcomes were measured using four items: pain, length of hospital stay, speed of recovery, and complications. Logistic regression model was applied to determine whether the unmet expectations influence HRQOL in LLDs. Odds ratios with 95% confidence interval were used.

Results

The percentage of the participants who reported that their actual experiences for pain, speed of recovery, hospital stay, and complications were worse than expected were 34.7%, 22.6%, 9.7%, and 7.3%, respectively. Unmet expectations about surgical outcomes were significantly associated with physical and mental HRQOL after controlling for age, sex, education level, income, postoperative complications, recipients’ death, time since donation, and satisfaction with the decision to donate.

Conclusion

LLDs should be supported in obtaining more accurate and realistic information about surgical outcomes to decrease unmet expectations, which may help improve their quality of life.

Long-term follow-up of living liver donors: A single-center experience

Living donors are healthy individuals who are exposed to a major surgical procedure during which a major part of their liver is resected. Data on the long-term consequences of living liver donation are scarce. This study examined clinical, laboratory, and long-term health-related quality of life (HRQoL) in 237 living liver donors and 239 matched controls during 48-168 months of postdonation follow-up. We used the 36-item short-form health survey (SF-36), version 1. The scores for the four following subscales were higher in nondonors than in donors: physical functioning (p = 0.009), role limitations due to physical health (p = 0.002), energy/fatigue (p < 0.001), and bodily pain (p < 0.001). The scores on the eight subscales of the SF-36 were higher in donors with living recipients than in donors whose recipients died (p < 0.001). Our results suggest that living donor right hepatectomy is safe and results in a postdonation HRQoL similar to that of nondonors in those donors whose recipients are healthy, whereas donors whose recipients die have a lower HRQoL that is significantly negatively correlated with the time since recipient death and improves over time.

Healthy Spouses can be Considered as Living Liver Donors

BACKGROUND

Spousal donors have gradually been accepted as an alternative living liver donors to alleviate the organ shortage and prevent donations from children. No information is available regarding the effects of spousal donation on donor safety and recipient outcomes. Our purpose in this study was to determine how spousal liver grafts in living donor liver transplantation (LDLT) affect donor safety and recipient outcomes compared with those of LDLT from children.

METHODS

We retrospectively analyzed 656 patients, including spouses and children, who underwent a right or extended right hepatectomy for living liver donation between January 2009 and December 2018.

RESULTS

Spouses represented 18.8% (n = 123) of living liver donors. Female donors comprised 78.9% (n = 97) of spousal donors, and the proportion of male donors in the children group was 72.6% (n = 387). The mean donor operation time of the spousal group was shorter than that of the children group (330 min vs. 358 min; P = 0.011), and the complication rate in the spousal group was lower than that in the children group (12.2% vs. 22.9%; P = 0.006). However, there were no differences in severe complication rates, hospitalization, or liver function tests between the 2 groups at 3 months after donor surgery. The overall survival of recipients in the spousal group was not reduced compared to that of recipients in the children group.

CONCLUSION

The present study suggests that, with careful selection, spousal donation is feasible and safe in LDLT.

Health-Related Quality of Life in Predominantly Young Parental Living Liver Donors: A Cross-Sectional Study in China

Objective: The health-related quality of life (HRQoL) of donors deserves attention and must be considered for a long time. Many of the published studies had small sample sizes, and research from mainland China, in particular, is scant. Thus, this study aimed to investigate the HRQoL of living liver donors and identify the influencing factors of the HRQoL in mainland China.

Methods: This is a cross-sectional study. The data were collected from the liver transplantation center, the Tianjin First Center Hospital, China. Living liver donors older than 18 years and at a minimum of 1-month, post-donation was included. The HRQoL was evaluated using the Medical Outcome Study Short form 36 (SF-36). Sociodemographic and clinical-related variables, HRQoL status, and its potential impact factors were analyzed.

Results: A total of 382 living liver donors completed the survey. The median number of months post-donation was 25, and parental donors (99.2%) were the most frequent relationship. The majority of the participants (372, 97.4%) donated their left lateral lobes. Thirty-two (8.4%) donors suffered complications, and of them, 7 suffered from biliary leakage (1.8%), which was the most common one in this study. The physical functioning (PF), role–physical (RP), bodily pain (BP), general health (GH), social functioning (SF), role–emotional (RE), and mental health (MH) scores among the living liver donors were significantly better than those of the Chinese norms. Short-time post-donation [odds ratio (OR): 0.008; p < 0.001] and male recipients (OR:0.195; p = 0.024) were associated with the likelihood of a poor physical related quality of life.

Conclusions: Despite, in general, good HRQoL outcomes, we also believed that liver donation has an obvious influence on the physical functions of liver donors. More attention and long-term follow-ups are necessary for donors at higher risk based on identified influencing factors and correlates.

Global experience and perspective on anonymous nondirected live donation in living donor liver transplantation

Anonymous nondirected living liver donation (ANLLD), sometimes referred to as "altruistic" donation, occurs when a biologically unrelated person comes forward to donate a portion of his/her liver to a transplant candidate who is unknown to the donor. Here, we explore the current status of ANLLD with special consideration of published reports; US experience; impact on donor psychosocial outcomes; barriers to donation; and current global trends with respect to ethical considerations. Between 1998 and 2019, 105 anonymous nondirected living liver donor (ND-LLD) transplants have been documented in the US Scientific Registry of Transplant Recipients. Sixteen donors (15%) were reported to experience a postoperative complication. Currently, 89 donors remain alive (85%), 16 (15%) have unknown status, and none are confirmed deceased. Although there are only a handful of case series, these data suggest that ANLLD is a feasible option. While there are no liver-specific data, studies involving anonymous nondirected kidney donors suggest that anonymous donation does not adversely impact psychosocial outcomes in donors or recipients. There are substantial financial burdens and ethical considerations related to ANLLD. Further studies are required to assess donor demographics, psychosocial motivations, long-term health-related quality of life, and financial impact of ANLLD.
