Summary

Acute-on-chronic liver failure (ACLF) is a syndrome associated with a high short- term mortality. Early identification of patients at high risk is important to determine emergency for transplantation and prioritize the need for intensive care unit. Unbalanced systemic inflammatory response is closely associated with mortality in ACLF patients. This systemic inflammatory response in ACLF increases liver and splenic stiffness stiffnes, which can be detected by transient elastography. Very few studies have been done in past evaluating liver and splenic stiffness as prognostic tool in patients of ACLF. These studies have taken only single value of liver and splenic stiffness as prognostic tool. No follow up study have yet been done assessing acute change in liver and splenic stiffness in ACLF. In this study, we hypothesize that acute change in liver and splenic stiffness at 7th \& 14 th day predicts outcome in ACLF patients. With this study, we aim to evaluate whether acute changes in liver and splenic stiffness at 7th \& 14th day predicts outcome at 3 months in patients of ACLF.

Detailed description

Study Design 1 year prospective cohort study Hypothesis: We hypothesize that acute change in liver and splenic stiffness at 7th \& 14 th day predicts outcome in ACLF patients Aim and Objective - Primary objective: To study the change in liver and splenic stiffness values at day 7 from baseline at day 1 between those with or without transplant free survival at Day 90. Secondary objectives: 1\) To study the change in liver and splenic stiffness values at day 14 from baseline at day 1 between those with or without transplant free survival at Day 90. 1. To evaluate association of baseline and change in liver and splenic stiffness with different etiologies of ACLF 2. To evaluate association of baseline liver and splenic stiffness with grade of esophageal varices in ACLF patients. 3. To evaluate association of baseline and change in liver and splenic stiffness with pattern of organ failures. 4. To evaluate association of changes in level of biochemical inflammatory markers with change in liver and splenic stiffness. 5. To evaluate association of baseline liver and splenic stiffness with severity of ACLF by AARC-ACLF score,CLIF-C-ACLF score, MELD-Na and CTP at presentation. 6. To evaluate change in liver and splenic stiffness with change in AARC-ACLF score and CLIF-C-ACLF score. Methodology: Study population All the consecutive patients of ACLF admitted in Hepatology wards will be evaluated for inclusion criteria Study design: Prospective cohort study Study period: 1 year after IEC approval. Sample size: Consecutive patients of ACLF from approval of study to 12 months. 200 patients will be enrolled in our study Intervention: None Monitoring and assessment: All enrolled patients will undergo detailed evaluation by thorough history, clinical examination and relevant laboratory investigations. Patients will be graded as per AARC score grade I (5-7), II (8-10), III (11-15). CBC /NLR, KFT, LFT, PT/INR at baseline and alternate day, till discharge or death/Liver transplantation. TNF alpha, IL-6, CRP, ferritin, lactate at day 1, day 7 and day 14. AARC-ACLF score and CLIF-C-ACLF score at day 1, day 7 and day 14.USG abdomen and hepatic vein, porto-splenic doppler study will be performed in all cases and triple phase CT of abdomen when there will be suspicion of HCC. Fibroscan of liver and spleen at day 1, day 7 and day 14.UGI endoscopy will be performed within 7 days. Initial Liver and Splenic stiffness and follow-up tests (Liver and splenic stiffness, TNF-alpha, IL-6) will be done free of cost. STATISTICAL ANALYSIS: Baseline data will be expressed as a proportion(%), the continuous data will be presented as mean+-SD OR mean ± SD or median ( IQR). To compare between the groups, either, Student's t-test/ Mann Whitney test will be applied, as appropriate. The categorical data will be analysed using χ2test or Fisher's exact test. The change between pre- and post-values will be analysed using paired t-test or McNemar test. Significance defined as 2-tailed p-value of less than 0.05. Survival curves will be represented using Kaplan-Meier method. ITT/ Per protocol analysis will be carried out for final result assessment. The data will be entered in Microsoft excel format and to be analysed using SPSS version 22 (IBM corp Ltd.; Armonk NY, USA). Adverse effects: NA
