Item Management of Acute Liver Failure: A Pediatric Perspective(Springer, 2018) Bhatt, Heli; Rao, Girish S.; Pediatrics, School of MedicinePurpose of review: Pediatric acute liver failure is a rare, complex, rapidly progressing, and life-threatening illness. Majority of pediatric acute liver failures have unknown etiology. This review intends to discuss the current literature on the challenging aspects of management of acute liver failure. Recent findings: Collaborative multidisciplinary approach for management of patients with pediatric acute liver failure with upfront involvement of transplant hepatologist and critical care specialists can improve outcomes of this fatal disease. Extensive but systematic diagnostic evaluation can help to identify etiology and guide management. Early referral to a transplant center with prompt liver transplant, if indicated, can lead to improved survival in these patients. Summary: Prompt identification and aggressive management of pediatric acute liver failure and related comorbidities can lead to increased transplant-free survival and improved post-transplant outcomes, thus decreasing mortality and morbidity associated with this potential fatal condition.Item Portal vein thrombosis, mortality and hepatic decompensation in patients with cirrhosis: A meta-analysis(Baishideng Publishing Group Co (World Journal of Hepatology), 2015-11-28) Stine, Jonathan G.; Shah, Puja M.; Cornella, Scott L.; Rudnick, Sean R.; Ghabril, Marwan S.; Stukenborg, George J.; Northup, Patrick G.; Department of Medicine, IU School of MedicineAIM: To determine the clinical impact of portal vein thrombosis in terms of both mortality and hepatic decompensations (variceal hemorrhage, ascites, portosystemic encephalopathy) in adult patients with cirrhosis. METHODS: We identified original articles reported through February 2015 in MEDLINE, Scopus, Science Citation Index, AMED, the Cochrane Library, and relevant examples available in the grey literature. Two independent reviewers screened all citations for inclusion criteria and extracted summary data. Random effects odds ratios were calculated to obtain aggregate estimates of effect size across included studies, with 95%CI. RESULTS: A total of 226 citations were identified and reviewed, and 3 studies with 2436 participants were included in the meta-analysis of summary effect. Patients with portal vein thrombosis had an increased risk of mortality (OR = 1.62, 95%CI: 1.11-2.36, P = 0.01). Portal vein thrombosis was associated with an increased risk of ascites (OR = 2.52, 95%CI: 1.63-3.89, P < 0.001). There was insufficient data available to determine the pooled effect on other markers of decompensation including gastroesophageal variceal bleeding or hepatic encephalopathy. CONCLUSION: Portal vein thrombosis appears to increase mortality and ascites, however, the relatively small number of included studies limits more generalizable conclusions. More trials with a direct comparison group are needed.Item Viscoelastic Hemostatic Assays: A Primer on Legacy and New Generation Devices(MDPI, 2022-02-07) Volod, Oksana; Bunch, Connor M.; Zackariya, Nuha; Moore, Ernest E.; Moore, Hunter B.; Kwaan, Hau C.; Neal, Matthew D.; Al-Fadhl, Mahmoud D.; Patel, Shivani S.; Wiarda, Grant; Al-Fadhl, Hamid D.; McCoy, Max L.; Thomas, Anthony V.; Thomas, Scott G.; Gillespie, Laura; Khan, Rashid Z.; Zamlut, Mahmud; Kamphues, Peter; Fries, Dietmar; Walsh, Mark M.; Medicine, School of MedicineViscoelastic hemostatic assay (VHAs) are whole blood point-of-care tests that have become an essential method for assaying hemostatic competence in liver transplantation, cardiac surgery, and most recently, trauma surgery involving hemorrhagic shock. It has taken more than three-quarters of a century of research and clinical application for this technology to become mainstream in these three clinical areas. Within the last decade, the cup and pin legacy devices, such as thromboelastography (TEG® 5000) and rotational thromboelastometry (ROTEM® delta), have been supplanted not only by cartridge systems (TEG® 6S and ROTEM® sigma), but also by more portable point-of-care bedside testing iterations of these legacy devices (e.g., Sonoclot®, Quantra®, and ClotPro®). Here, the legacy and new generation VHAs are compared on the basis of their unique hemostatic parameters that define contributions of coagulation factors, fibrinogen/fibrin, platelets, and clot lysis as related to the lifespan of a clot. In conclusion, we offer a brief discussion on the meteoric adoption of VHAs across the medical and surgical specialties to address COVID-19-associated coagulopathy.
