With an increasing incidence over time and a cumulative effect on cognition, HE adversely effects quality of life, morbidity and mortality in patients with cirrhosis. HE can range from minimal or covert (MHE/CHE) to overt and symptomatic (OHE). HE has profound impacts on the health and wellbeing of patients and their families and caregivers. Effective treatments could improve the quality of life for all those affected. In this article, we discuss the existing treatments for HE and focus on the potential role of albumin in the treatment of HE. Currently approved therapies for HE (lactulose and rifaximin) are focused on decreasing the formation of ammonia in the gastrointestinal tract. Among the many agents with alternative mechanisms being investigated for treatment of HE, albumin has been studied in clinical trials with acute (≤ 3 days), short-term (up to 2 weeks) prolonged (&gt; 2 weeks) and long-term administration (months). Current studies indicate that acute or short-term administration of albumin does not provide significant benefit for patients with OHE. However, there is increasing evidence that prolonged or long-term albumin therapy can help improve cognition in OHE and prevent recurrence. Additional studies are needed to substantiate these positive findings for longer term administration of albumin in HE and to increase our comprehension of the pharmacologic basis of the effects of albumin.</div></div>","PeriodicalId":7979,"journal":{"name":"Annals of hepatology","volume":"30 1","pages":"Article 101751"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The procedure was performed in 51% (20/39) of the patients within a period of just 4 years (2019 to 2024). The main indication was secondary to variceal gastrointestinal bleeding (59%), followed by refractory ascites (36%). Additionally, 33.3% presented some degree of portal vein thrombosis, and 33.3% had reported hepatic encephalopathy episodes before the procedure. The average MELD Na score was 15.4. Only three patients experienced hemorrhagic complications related to the procedure, with one resulting in death. 53.8% reported some degree of hepatic encephalopathy after the procedure. One-year survival was analyzed, showing 47.4% in patients whose procedure was performed before 2019 versus 76.9% in the period between 2020 and 2023 (p 0.095). Four patients underwent transplants after TIPS, without complications.</div></div><div><h3>Conclusions</h3><div>We have observed a progressive increase in the indication for TIPS over time at our center, with half of the cases concentrated in the last four years. In addition, survival outcomes appear to be better, probably due to improved patient selection and more timely indications. The procedure was safe, with a low rate of acute complications and an incidence of encephalopathy similar to that reported in the literature. Longer-term follow-up will allow us to verify its effectiveness in our population</div></div>","PeriodicalId":7979,"journal":{"name":"Annals of hepatology","volume":"29 ","pages":"Article 101665"},"PeriodicalIF":3.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
