Clinical Trial Summary

Acute on chronic liver failure (ACLF) is a syndrome characterized by acute decompensation of chronic liver disease associated with organ failures and high short- term mortality. Development of systemic inflammation and subsequent organ failures determines is associate with poor outcome and short-term mortality. Previous studies have shown that endothelial injury leading to increase in levels of and exhaustion of its cleaving protein a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS 13) which promotes the platelet microthrombi formation and subsequent organ ischemia. We propose that the vWF : ADAMTS 13 ratio can be predict the organ failure development and subsequent mortality in ACLF patients, which is considered to be a inflammatory state.


Description:

Null Hypothesis: Systemic inflammation in acute-on-chronic liver failure (ACLF) leads to endothelial injury leading to increased vWF levels and exhaustion of its cleaving protein ADAMTS 13 which promotes the platelet microthrombi formation, leading to subsequent organ failures which are the strong predictors of short term mortality. AIM: - To evaluate the role of plasma Von Willebrand factor antigen to ADAMTS-13 activity ratio in predicting organ failure in acute on chronic liver failure (ACLF) patients Objective - Primary objective: To study efficacy of Von Willebrand factor antigen to ADAMTS-13 activity ratio in predicting development of organ failures at day 7 Secondary objectives: 1. To study efficacy of vWF Ag : ADAMTS-13 ratio in predicting 28 days transplant free survival. 2. To study efficacy of day 1 and day 4 vWF and ADAMTS 13 level with in predicting development of organ failures at day. 3. To efficacy of day 1 and day 4 vWF and ADAMTS 13 level with in predicting 28 days transplant free survival. 4. To compare vWF, ADAMTS 13 level and vWF Ag : ADAMTS-13 ratio across different grades of AARC ACLF. 5. To compare vWF, ADAMTS 13 level and vWF Ag : ADAMTS-13 ratio with AARC, MELD, SOFA, CLIF-ACLF scores. 6. To compare the impact of different therapies on vWF, ADAMTS 13 level and vWF Ag : ADAMTS-13 ratio (PLEX, Etiology specific : steroids, antivirals). Study population: All the patients with age >18 years who are diagnosed having ACLF fulfilling APASL ACLF criteria Study design: Prospective cohort study Study period: September 2023 - December 2023 Intervention: This is a prospective cohort study and will be conducted at ILBS New Delhi The following data will be recorded for each patient: H/o of jaundice, distension abdomen, swelling feet, altered sensorium, vomiting of blood or passing melena Acute and chronic etiology of ACLF Clinical examination: Ascites with grade, glass glow coma scale, west heaven hepatic encephalopathy grade, heart rate, blood pressure, urine output Height, weight and BMI Day 0 - Routine investigations: Hemogram, TLC, DLC, KFT, LFT, Prothrombin time/INR D-Dimer, Fibrinogen, ROTEM, arterial lactate Von Willebrand factor antigen, ADAMTS 13 activity Organ failure assessment with SOFA score Disease Severity assessment with AARC/MELD/CLIF-ACLF DAY 4 - Routine investigations: Hemogram, TLC, DLC, KFT, LFT, Prothrombin time/INR D-Dimer, Fibrinogen, ROTEM, arterial lactate Von Willebrand factor antigen, ADAMTS 13 activity Organ failure assessment with SOFA score Disease Severity assessment with AARC/MELD/CLIF-ACLF DAY 7: - Routine investigations: Hemogram, TLC, DLC, KFT, LFT, Prothrombin time/INR D-Dimer, Fibrinogen, ROTEM, arterial lactate Von Willebrand factor antigen, ADAMTS 13 activity Organ failure assessment with SOFA score Disease Severity assessment with AARC/MELD/CLIF-ACLF Day 28- Final outcome assessment death or alive Total five organs parameters will be assessed: Kidney, Brain, Coagulation, Circulatory, Respiratory Liver failure will be assessed by AARC score: Extrahepatic organ failure/dysfunction will be assessed by CLF SOFA score Organ failure will be defined as: Renal failure: Creatinine >2.0 mg/dL or RRT Cerebral failure: Grade 3-4 Circulatory failure: Vasopressor requirement Respiratory failure: PaO2/FiO2 <200 or SpO2/FiO2 <214 Monitoring and assessment: All the parameters of the objective and also noted any adverse effects. STATISTICAL ANALYSIS: The data will be entered in Microsoft excel and will be analyzed using SPSS version 22. The categorical data will be analysed using Chi square/Fissure test. Exact test and continuous data will be compiled using t-test. Besides this the univariate and multivariate survival analysis will be carried out using Cox regression method. Kaplan-Meier technique will be applied for further analysis. P-value<0.05 will be considered as significant. Adverse effects: NA
