    Advancements in MELD Score and Its Impact on Hepatology
    (Thieme Medical Publishers, Inc., 2024) Hudson, David; Valentin Cortez, Francisco Javier; Hurtado Díaz de León, Ivonne; Malhi, Gurpreet; Rivas, Angélica; Afzaal, Tamoor; Rad, Mahsa Rahmany; Díaz Piga, Luis Antonio; Khan, Mohammad Qasim; Arab Verdugo, Juan Pablo
    There continues to be an ongoing need for fair and equitable organ allocation. The Model for End-Stage Liver Disease (MELD) score has evolved as a calculated framework to evaluate and allocate patients for liver transplantation objectively. The original MELD score has undergone multiple modifications as it is continuously scrutinized for its accuracy in objectively representing the clinical context of patients with liver disease. Several refinements and iterations of the score have been developed, including the widely accepted MELD-Na score. In addition, the most recent updated iteration, MELD 3.0, has been created. The MELD 3.0 calculator incorporates new variables such as patient sex and serum albumin levels and assigns new weights for serum sodium, bilirubin, international normalized ratio, and creatinine levels. It is anticipated that the use of MELD 3.0 scores will reduce overall waitlist mortality and enhance access for female liver transplant candidates. However, despite the emergence of the MELD score as one of the most objective measures for fair organ allocation, various countries and healthcare systems employ alternative methods for stratification and organ allocation. This review article will highlight the origins of the MELD score, its iterations, the current MELD 3.0, and future directions for managing liver transplantation organ allocation.

    Moderate alcohol-associated hepatitis: A real-world multicenter study
    (Springer, 2025) Idalsoaga Ferrer, Francisco Javier; Diaz, Luis Antonio; Dunn, Winston; Mehta, Heer; Munoz, Karen; Caldentey, Vicente; Arnold, Jorge; Ayares, Gustavo; Mortuza, Rokhsana; Sarin, Shiv K.; Maiwall, Rakhi; Zhang, Wei; Qian, Steve; Simonetto, Douglas; Singal, Ashwani K.; Elfeki, Mohamed A.; Ramirez-Cadiz, Carolina; Malhi, Gurpreet; Ahmed, Adan; Homsi, Hoomam; Abid, Zinia; Cabezas, Joaquin; Echavarria, Victor; Poca, Maria; Soriano, German; Cuyas, Berta; Cots, Meritxell Ventura; Higuera-De La Tijera, Maria Fatima; Ayala-Valverde, Maria; Perez, Diego; Gomez, Jaime; Abraldes, Juan G.; Al-Karaghouli, Mustafa; Jalal, Prasun K.; Ibrahim, Mohamad A.; Garcia-Tsao, Guadalupe; Goyes, Daniela; Skladany, Lubomir; Havaj, Daniel J.; Sulejova, Karolina; Selcanova, Svetlana Adamcova; Rincon, Diego; Chacko, Kristina R.; Restrepo, Juan C.; Yaquich, Pamela; Toro, Luis G.; Shah, Vijay; Arrese Jiménez, Marco Antonio; Kamath, Patrick S.; Bataller, Ramon; Arab Verdugo, Juan Pablo
    Background: Severe alcohol-associated hepatitis (sAH) is a well-characterized disease with high short-term mortality. However, there is limited research on those with a "less severe condition" (moderate AH). This study aims to characterize in-depth patients with moderate AH (mAH), including the performance of mortality scoring systems, key prognostic factors, and survival over time. Methods:A multicenter retrospective cohort study (2009-2019) included patients with mAH (MELD score <= 20 at admission). Cox regression and receiver operating characteristic curves with AUC were used for analysis. Results:We included 1845 patients with AH (20 centers, 8 countries) between 2009 and 2019. mAH was defined as a MELD score <= 20 at admission. Twenty-four percent met the criteria for an mAH episode. Patients with mAH tend to be older and have a higher proportion of females, with a median MELD of 17 (15-19), Maddrey discriminant function (mDF) of 33 (22-40), the trajectory of serum bilirubin of 0.83 (0.60-1.21), and neutrophil-to-lymphocyte ratio (NLR) of 5 (2.96-8.60). The primary causes of death in mAH included multiple organ failure (34.1%) and infections (16.6%). The cumulative survival rates at 30, 90, and 180 days were 94.3%, 90.4%, and 88.2%, respectively. In multivariable analysis, age was the only significant predictor of 30-day mortality (HR 1.49, 95% CI: 1.27-1.76, p<0.001). Mortality prediction models showed poor performance, with AUC for MELD (0.671), mDF (0.726), trajectory of serum bilirubin (0.733), and NLR (0.697). Conclusions:Patients with moderate AH exhibited a mortality of 11.8% at 6 months, primarily driven by multiple organ failure and infections. These patients also exhibit a different clinical profile compared to those with sAH. Tailored models and therapeutic strategies are needed to improve long-term outcomes in mAH.
