Although most cases follow a benign and self-limited course, less than 5% of patients with HAV infection progress to acute liver failure, which carries mortality rates of 13%-33% depending on access to liver transplantation (LT). The identification of clinical and biochemical predictors of adverse outcomes is crucial to improve early risk stratification, optimize patient management, and guide timely referral to transplant centers.<\/jats:p>\n                  <jats:p>AIM<\/jats:p>\n                  <jats:p>To assess the utility of clinical and biochemical variables and prognostic scores in predicting mortality and the need for LT in patients with acute HAV infection.<\/jats:p>\n                  <jats:p>METHODS<\/jats:p>\n                  <jats:p>We conducted a retrospective case series of all patients hospitalized at Medica Sur Clinic between 2018 and 2024 who were positive for immunoglobulin M antibodies for HAV. Clinical and laboratory data were collected from patients\u2019 electronic medical records. Continuous variables were summarized as the means \u00b1 SD or median and interquartile range and compared using Student\u2019s t -test or the Mann-Whitney U  test, as appropriate. Categorical variables were expressed as frequencies and percentages and compared using the \u03c7 2 test or Fisher\u2019s exact test.<\/jats:p>\n                  <jats:p>RESULTS<\/jats:p>\n                  <jats:p>A total of 69 patients with HAV infection (mean age, 38 \u00b1 11 years; 65% male) were included. 14% of patients had a history of hepatic steatosis, 10% had type 2 diabetes, and 45% were smokers. Acute liver injury was observed in 47 patients (68%), acute liver failure was detected in five patients (7.2%), and mortality or LT occurred in three patients (4.3%; two deaths and one transplant). Patients who died or required orthotopic LT were older, and they had higher heart and respiratory rates at admission. These patients additionally exhibited greater liver dysfunction, including higher bilirubin and transaminase levels, prolonged coagulation times, lower sodium and albumin levels, and worse albumin-bilirubin scores. Severity scores [model for end-stage liver disease (MELD), MELD with sodium, MELD version 3.0] were significantly higher in patients with complications than in those without complications.<\/jats:p>\n                  <jats:p>CONCLUSION<\/jats:p>\n                  <jats:p>Advanced age, elevated severity, and higher albumin-bilirubin scores emerged as predictors of adverse outcomes in patients with HAV infection, and consideration of these factors could guide the need for more intensive monitoring strategies. These findings highlight the importance of incorporating prognostic scoring systems into routine clinical evaluation to improve outcomes in high-risk patients.<\/jats:p>","DOI":"10.4240\/wjgs.v18.i1.112767","type":"journal-article","created":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T03:11:54Z","timestamp":1768965114000},"source":"Crossref","is-referenced-by-count":0,"title":["Predictors of mortality and liver transplant requirement in patients with hepatitis A virus: A case series from Mexico"],"prefix":"10.4240","volume":"18","author":[{"given":"Cristian Alejandro","family":"Bautista-Mondrag\u00f3n","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alejandra Madeleine","family":"Mijangos-Trejo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Octavio","family":"Gonz\u00e1lez-Chon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"Mondrag\u00f3n-Ratkovich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norberto Carlos","family":"Ch\u00e1vez-Tapia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2060","published-online":{"date-parts":[[2026,1,27]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v27.i16.1691"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v27.i47.8081"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/j.rgmx.2017.10.004"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/S1665-2681(19)31032-4"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.3390\/v13101900"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.5604\/01.3001.0012.7857"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1016\/S1665-2681(19)31531-5"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1053\/jhep.2001.22172"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1053\/gast.2003.50016"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2021.08.050"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.14309\/crj.0000000000000763"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2014.57.9151"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1111\/liv.13527"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2016.12.003"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1016\/S1665-2681(19)31438-3"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1093\/ofid\/ofz467"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1478-3231.2008.01887.x"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0268469"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2018.10.037"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1089\/vim.2021.0045"}],"container-title":["World Journal of Gastrointestinal Surgery"],"original-title":[],"link":[{"URL":"https:\/\/www.wjgnet.com\/1948-9366\/full\/v18\/i1\/112767.htm","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.wjgnet.com\/1948-9366\/full\/v18\/i1\/112767.htm","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T03:12:39Z","timestamp":1768965159000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.wjgnet.com\/1948-9366\/full\/v18\/i1\/112767.htm"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,27]]},"references-count":20,"journal-issue":{"issue":"1"},"alternative-id":["112767"],"URL":"https:\/\/doi.org\/10.4240\/wjgs.v18.i1.112767","relation":{},"ISSN":["1948-9366"],"issn-type":[{"value":"1948-9366","type":"print"}],"subject":[],"published":{"date-parts":[[2026,1,27]]}}}
