Management of Disseminated Intravascular Coagulation in Acute-on-Chronic Liver Failure
Pathophysiology and Diagnosis
- Standard coagulation tests like INR have poor correlation with bleeding risk in critically ill cirrhotic patients as they only measure procoagulant factors without accounting for concurrent anticoagulant deficiencies 2
- Viscoelastic testing provides more functional evaluation of coagulation but optimal cutoffs for guiding therapy in ACLF are not established 2
Treatment Approach
- Treatment of the underlying cause of ACLF is the fundamental intervention, according to the Journal of Hepatology 3
- Early identification and management of precipitating factors such as bacterial infections, GI bleeding, or drug toxicity is crucial for patient survival 3
- Patients should ideally be admitted to intensive care or intermediate care units, with early referral to transplant centers if appropriate, as recommended by the Journal of Hepatology 3
- In patients with active bleeding, maintain platelet count >50×10⁹/L 1
- In patients with active bleeding, administer 15-30 mL/kg of plasma fresh frozen plasma (PFC) 1
- Consider fibrinogen replacement with cryoprecipitate or fibrinogen concentrate if levels remain <1.5 g/L despite PFC 1
- Avoid prophylactic transfusions based solely on laboratory values, as per Praxis Medical Insights 1
- Consider platelet transfusion only if high risk of bleeding and platelet count <20×10⁹/L 1
Organ Support
- Provide appropriate organ support as needed, such as vasopressors for hypotension, ventilation for respiratory failure, etc., as recommended by the Journal of Hepatology 3
- Consider renal replacement therapy for patients with acute kidney injury meeting criteria for this treatment, according to the Journal of Hepatology 3
- Extracorporeal liver support systems have not shown significant survival benefit in ACLF and are not recommended by the Journal of Hepatology 3
Infection Prevention
- Implement infection prevention measures as infections can trigger or worsen both ACLF and DIC, as suggested by Hepatology 2
- Remove unnecessary catheters, limit hospital stay, ensure vaccines are up to date, and stop unnecessary medications like PPIs, as recommended by Hepatology 2
- Provide early and appropriate antibiotic therapy for infections, with de-escalation once culture results return, according to Hepatology 2
