RESUMO
Alcohol liver disease is one of the main indications for liver transplantation (LT). Currently, an abstinence period <6 months is required to include a patient with alcohol liver disease on the waiting list, a period that has not been shown to reduce the risk of relapse. Alcoholic hepatitis is characterized by hepatic decompensation secondary to recent, excessive consumption of alcohol, and LT may be the option in a well-selected group of patients who do not respond to medical treatment, but due to established sobriety intervals are excluded, this requires a change in the criteria established by the committees. We propose an evaluation algorithm to consider alcoholic hepatitis unresponsive to medical treatment for LT.
La enfermedad hepática por alcohol es una de las principales indicaciones de trasplante hepático (TH). Actualmente se requiere un período de abstinencia > 6 meses para incluir a un paciente con enfermedad hepática por alcohol en lista de espera de TH, periodo que no ha demostrado disminuir el riesgo de recaída. La hepatitis aguda por alcohol se caracteriza por una descompensación hepática secundaria a un consumo de alcohol excesivo reciente, y el TH puede ser la única opción en un grupo bien seleccionado de pacientes que no responden al tratamiento médico, pero debido a los intervalos de sobriedad establecidos son excluidos, y esto requiere un cambio en los criterios establecidos por los comités. Proponemos un algoritmo de evaluación para considerar para TH la hepatitis aguda por alcohol no respondedora a tratamiento médico.

BACKGROUND: The safety and efficacy data of the different types of available vaccines is still needed. The goal of the present analysis was to evaluate the humoral response to the COVID-19 vaccines in orthotopic liver transplant (OLT) recipients. METHODS: Participants were included from February to September 2021. No prioritized vaccination roll call applied for OLT patients. Controls were otherwise healthy people. Blood samples were drawn after 15 days of the complete vaccine doses. The samples were analyzed according to the manufacturer's instructions using the Liaison XL platform from DiaSorin (DiaSorin S.p.A., Italy), and SARS-COV-2 IgG II Quant (Abbott Diagnostics, IL, USA). RESULTS: A total of 187 participants (133 OLT, 54 controls, median age: 60 years, 58.8% women) were included for the analysis; 74.3% had at least one comorbidity. The serologic response in OLT patients was lower than in controls (median 549 AU/mL vs. 3450 AU/mL, respectively; p = 0.001). A positive humoral response was found in 133 OLT individuals: 89.2% with BNT162b2 (Pfizer-BioNTech), 60% ChAdOx1 nCOV-19 (Oxford-AstraZeneca), 76.9% with CoronaVac (Sinovac, Life Sciences, China), 55.6% Ad5-nCov (Cansino, Biologics), 68.2% Gam-COVID-Vac (Sputnik V) and 100% with mRNA-1273. In controls the serological response was 100%, except for Cansino (75%). In a multivariable model, personal history of COVID-19 and BNT162b2 inoculation were associated with the serologic response, while the use of prednisone (vs. other immunosuppressants) reduced this response. CONCLUSION: The serologic response to COVID-19 vaccines in OLT patients is lower than in healthy controls. The BNT162b2 vaccine was associated with a higher serologic response.
