Li X, Ouyang T, Belcher JM, Patidar KR, Cullaro G +17 more
Plain English This study looked at patients with cirrhosis who developed acute kidney injury (AKI) while hospitalized and how their response to treatment affected their survival and the timing of liver transplants. Out of 317 patients, those who responded to AKI treatment had a better chance of surviving for 90 days (89.4% compared to 76.2% for those who didn't respond) but were less likely to get a liver transplant (45.9% compared to 61.2%). These findings are important because they show that while effective treatment of AKI helps patients survive longer, it may delay their access to a liver transplant.
Who this helps: This helps patients with cirrhosis and their doctors by highlighting the need for effective AKI treatment during hospitalization.
Controversies in terlipressin and transplantation in the United States: How do we MELD the two?
2024
Liver transplantation : official publication of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society
Plain English This study examines the use of terlipressin, a medication recently approved in the U.S. for treating severe kidney issues related to liver disease, known as hepatorenal syndrome-acute kidney injury (HRS-AKI). Researchers discuss whether patients who respond well to terlipressin should have their eligibility for liver transplants protected under the MELD scoring system, which determines waitlist priority; they highlight that, while terlipressin might help some patients improve their chances, cost and availability pose serious challenges. It’s essential to ensure that all stakeholders, including healthcare providers and policymakers, work together to improve access to this treatment.
Who this helps: This helps patients with severe liver disease and their doctors.

Durable Clinical and Immunologic Advantage of Living Donor Liver Transplantation in Children.
2018
Transplantation
Przybyszewski EM, Verna EC, Lobritto SJ, Martinez M, Vittorio JM +5 more
Plain English Children who receive livers from living donors—usually parents—have better long-term outcomes than those receiving deceased-donor organs, but living donor transplants remain rare in the U.S. This study found that living-donor recipients also showed immunological advantages, with lower rejection rates likely tied to the partial genetic match with a parent donor. The data make a strong case for expanding living donor programs for children.
Leaning to the Left: Increasing the Donor Pool by Using the Left Lobe, Outcomes of the Largest Single-center North American Experience of Left Lobe Adult-to-adult Living Donor Liver Transplantation.
2016
Annals of surgery
Halazun KJ, Przybyszewski EM, Griesemer AD, Cherqui D, Michelassi F +5 more
Plain English Most adult living-donor liver transplants use the larger right lobe because of worries that the smaller left lobe won't provide enough liver mass to the recipient. This largest North American report on left lobe adult-to-adult living donor transplants showed comparable outcomes to right lobe grafts when donors and recipients were well selected. Left lobe donation is safer for donors and more feasible than commonly assumed.
