A rare but life-threatening cause of pancytopenia after liver transplantation is hemophagocytic syndrome. We present a 48-year-old woman who underwent liver transplantation and developed a hemophagocytic syndrome secondary to Epstein-Barr virus with a fatal course, despite initial treatment with immunosuppressants. The diagnosis was made based on the bone marrow aspiration, in which macrophages with phagocytic activity were observed, and clinical findings. Due to the very poor outcomes and high mortality, in patients with severe pancytopenia hemophagocytic syndrome should be excluded, and a bone marrow aspiration should be considered. • Hemophagocytic syndrome is a rare cause of severe pancytopenia after liver transplantation. • Hemophagocytic syndrome has a very high mortality during the posttransplant period. • The diagnosis should be done as promptly as possible.

Cirrhosis as a result of alcohol-related liver disease is one of the most common indications for liver transplantation (LT) in Spain. Patients presenting for LT should be checked for alcohol abuse in clinical interviews and use of laboratory tests to confirm abstinence. The ethyl-glucuronide (EtG) test is very sensitive and can be positive in urine up to 5 days after consumption. Our main objective is to know the rate of alcohol abstinence by using the urine EtG test in patients evaluated for LT and to assess its correlation with the clinical interviews and laboratory test. We conducted a prospective analysis of the results of the EtG in urine of patients evaluated for LT from January 2017 to March 2019 and its correlation with the medical and psychiatric interviews and with the laboratory test. We included 160 patients who were referred to LT evaluation. Among all cases, 84.1% were men, with an average age of 57.8 years. Alcohol-related liver disease was the most frequent cause (64.1%). Urine-EtG was positive in 10 patients (6.2%), 9 of them in patients with ALD and 1 in a patient with hepatitis C virus. The alcohol consumption was recognized by 80% of the patients in the clinical interview. Cases with positive EtG had higher levels of analytical parameters than those with a negative test. In our series, 6.2% of patients referred for LT evaluation had recently consumed alcohol. The determination of EtG in urine is probably an effective and objective technique in the detection of alcohol consumption to ensure abstinence in the LT candidates. • The determination of EtG is effective in detecting alcohol consumption. • Patients with positive EtG had higher levels of indirect laboratory markers. • A total of 80% of patients with positive EtG have admitted alcohol consumption.

Immunosuppressive calcineurin inhibitors have been associated with an increased risk of post-transplant malignancies. The mammalian target of rapamycin inhibitors (mTORi) is an alternative immunosuppressive regimen with an antineoplastic effect. The aim of the study was to determine the long-term survival of mTORi-treated recipients with de novo or recurring tumors after liver transplantation (LT). This retrospective analysis included mTORi-treated LT recipients between March 2013 and March 2019. We analyzed long-term survival and mTORi indications in an oncology setting in patients with de novo and recurrent malignancies after LT. Overall survival (OS) rate was compared from the Spanish Liver Transplant Registry (SLTR) data using the Kaplan-Meier method. High-risk hepatocellular carcinoma (HCC) was defined as microvascular invasion or satellite lesions as described in the liver explant. A total of 237 patients underwent LT during the study period; 111 patients underwent mTORi-based immunosuppression (48%, cancer was the main indication): 24.5% high-risk HCC; 24.4% HCC recurrence; 14.3% cholangiocarcinoma; and 36.7% de novo malignancies. The 1- and 5-year OS rates after LT in the mTORi group were 83% and 65%, respectively (SLTR group, 85% and 72.6%, respectively); 30.6% patients received mTORi monotherapy, and 38.7% patients had an early switch to mTORi in the first 3 months after oncologic diagnosis. mTORi monotherapy or oncologic treatment strategies had a nonsignificant association with prognosis. The OS rate was higher when the mTORi switch occurred early, 83% and 67%, respectively. mTORi-based immunosuppression may be a preferred option in patients transplanted with tumors. The OS rate was comparable to data from the SLTR. An mTORi early switch improves OS rate. • Mammalian target of rapamycin inhibitor (mTOR)–based immunosuppression may be a preferable option in patients transplanted with tumors. • The overall survival rate of mTOR inhibitor–treated patients was comparable to all patients collected by the Spanish Liver Transplant Registry. • Early switch to mTOR inhibitors after cancer diagnosis could have a benefit in long-term liver transplant recipients.
