Kernekoncepter
Early recognition and appropriate management are crucial in treating Acute Liver Failure.
Resumé
Acute liver failure (ALF) is a severe complication that requires prompt recognition and management. The American College of Gastroenterology (ACG) has published guidelines to aid clinicians in treating ALF effectively. The content covers the definition and differentiation of ALF, distinguishing it from acute-on-chronic liver failure (ACLF), special considerations for clinicians, advice for general management of ALF, and final takeaways for clinicians.
Definition and Differentiation
- ALF is a severe complication of liver injury that develops rapidly, leading to life-threatening complications.
- ALF is defined by a combination of factors, including elevated INR and hepatic encephalopathy.
- Distinguishing ALF from ACLF involves considering preexisting liver disease and clinical, laboratory, and imaging characteristics.
Special Considerations for Clinicians
- Grade 2 HE in ALF indicates a poor prognosis and requires close monitoring.
- Differentiating ALF from cirrhotic liver disease based on imaging can be challenging.
- The guidelines highlight the differences between MELD and KCC scores for predicting liver transplantation.
Advice for General Management of ALF
- CRRT is recommended for patients at risk of cerebral edema in ALF.
- Surveillance cultures are suggested due to the high incidence of infections in ALF patients.
- NAC is beneficial in ALF treatment, with few contraindications.
Final Takeaways
- Early contact with a liver transplant center is crucial for expedited patient transfer.
Statistik
ALF is defined by a combination of factors, including elevated INR and hepatic encephalopathy.
Patients with ACLF do not receive priority on transplant waitlists outside of the Model for End-Stage Liver Disease (MELD) score.
Development of grade 2 HE in ALF indicates a rapidly failing synthetic function of the liver.
CRRT is recommended for hyperammonemia in ALF.
NAC has been shown to improve outcomes in APAP-related ALF and other causes of ALF.
