Enhanced recovery for liver transplantation: recommendations from the 2022 International Liver Transplantation Society consensus conference

There is much controversy regarding enhanced recovery for recipients of liver transplants from deceased and living donors. The objectives of this Review were to summarise current knowledge on individual enhanced recovery elements on short-term outcomes, identify key components for comprehensive pathways, and create internationally accepted guidelines on enhanced recovery for liver-transplant recipients. The ERAS4OLT.org collaborative partnered by the International Liver Transplantation Society performed systematic literature reviews on the effect of 32 relevant enhanced perioperative recovery elements on short-term outcomes, and global specialists prepared expert statements on deceased and living donor liver transplantation. The Grading Recommendations, Assessment, Development and Evaluations approach was used for rating of quality of evidence and grading of recommendations. A virtual international consensus conference was held in January, 2022, in which results were presented, voted on by the audience, and discussed by an independent international jury of eight members, applying the Danish model of consensus. 273 liver transplantation specialists from 30 countries prepared expert statements on elements of enhanced recovery for liver transplantation based on the systematic literature reviews. The consensus conference yielded 80 final recommendations, covering aspects of enhanced recovery for preoperative assessment and optimisation, intraoperative surgical and anaesthetic conduct, and postoperative management for the recipients of liver transplants from both deceased and living donors, and for the living donor. The recommendations represent a comprehensive overview of the relevant elements and areas of enhanced recovery for liver transplantation. These internationally established guidelines could direct the development of enhanced recovery programmes worldwide, allowing adjustments according to local resources and practices.

Late-onset familial Mediterranean fever (FMF): a subset with distinct clinical, demographic, and molecular genetic characteristics

To determine the prevalence and characterize demographic, clinical, and genetic features of familial Mediterranean fever (FMF) of late onset, all patients experiencing their first FMF attack at age 40 years or more were identified using the computerized registry of our FMF clinic, and then thoroughly interviewed and examined. The control group consisted of 40 consecutive FMF patients, who arrived at the FMF clinic for their regular follow-up visit and were 40 years of age or older at the time of the examination. The severity of the disease in patients and controls was determined using a modified score, developed previously. Mutational analysis in the FMF gene was performed using a commercial kit. Only 20 of 4000 (0.5%) patients had late-onset FMF. These patients were mostly men, of non-North African origin, P < 0.05 compared to controls. All had abdominal attacks and in most these were the only manifestation of their disease, P < 0.001. None had chronic or prolonged manifestations of FMF, for example, amyloidosis, chronic arthritis, or protracted myalgia, P < 0.001. The response to treatment was good despite using low colchicine dose, P < 0.05. The overall severity score indicated a mild disease, P < 0.001. Mutational analysis revealed absence of M694V homozygosity, P < 0.01, compared to our regular FMF population. We conclude that the onset of FMF in a late age defines a milder form of disease with typical clinical, demographic, and molecular genetic characteristics.
