ABSTRACT
BACKGROUND: Anonymous living liver donations (ALLDs) raise ethical concerns regarding the donors' motivations. Thus, ALLDs are not as widely accepted as directed donations from friends and family. Literature on ALLDs is limited. Understanding this particular group of individuals is crucial, as they could further help mitigate the shortage of liver grafts worldwide. METHODS: A literature review was performed to identify current definitions, ethical considerations, different approaches, and barriers to ALLD worldwide. Furthermore, we present our current experience after the establishment of a protocol to enable an ALLD program in our center and surveyed potential donors to better understand their motives throughout the process. RESULTS: Literature regarding ALLD is scarce. Canada leads the experience with the majority of case reports published to date. Survey-based evaluation of this unique group of individuals reflects the selflessness nature of anonymous living donors and shows that most of them experience the donation as a positive and life-changing event. In our experience, 41 individuals initiated the process of ALLD during the study period. Most were lost to follow-up or deemed ineligible. Five candidates fully completed the donation process and successfully underwent living liver donation. Given that 2 candidates have a follow-up period <3 mo from donation, we have only included data on the first 3 donors in this analysis. Eight individuals (19.5%) responded to the survey with respondents sharing similar reasons for initiating ALLD but varied and multifactorial reasons for terminating. CONCLUSIONS: Different institutional protocols can be used to accomplish ALLD, including the one utilized by our institution. Adopting policies to allow for ALLDs and reducing modifiable factors that contribute to ending donation has the potential to increase grafts and decrease wait times.Supplemental Visual Abstract: http://links.lww.com/TP/C251.
ABSTRACT
BACKGROUND: Living donor liver transplantation offers an attractive option to reduce the waitlist mortality. However, in recent years, the rising prevalence of obesity and nonalcoholic fatty liver disease has posed a serious threat to the donor pool while simultaneously increasing demand for liver transplant. To our knowledge, there have been no major published studies in the United States documenting a diet and exercise intervention to expand the living donor pool. Hereby, we established a pilot program called "Lose Weight to Donate" and present our initial experience. METHODS: Our center instituted a remotely monitored diet and exercise pilot program to increase eligibility for living liver donation. Potential donors with any of the following were included: body mass index >30 kg/m2, hepatic steatosis >5% on screening MRI, or isolated hypertension. RESULTS: Over 19 mo, 7 individuals enrolled in the program of remote monitoring for at least 6-8 wk. Initial and follow-up abdominal MRI was performed in 5 of these individuals to assess steatosis, anatomy, and volume. Initial steatosis was highly variable (fat signal fraction range, 8%-26%). Follow-up MRI fat signal fraction values and hepatic volume all decreased to varying degrees. Ultimately, 2 of 7 individuals donated, whereas a third was approved, but the intended recipient was transplanted in the interim. CONCLUSIONS: These results indicate the feasibility of a remotely monitored program to expand donation in light of the rising incidence of hepatic steatosis and obesity.
