Efficacy and Safety of Early Initiation of Midodrine for Control and Prevention of Ascites and Its Related Complications in Acute-on-chronic Liver Failure.

Ascites is a cardinal and debilitating complication in patients with acute-on-chronic liver failure (ACLF), significantly correlating with disease severity and poor prognosis. The underlying pathophysiology is driven by severe splanchnic arterial vasodilation, which reduces effective arterial blood volume and triggers compensatory neurohumoral activation. This cascade leads to profound sodium retention, renal vasoconstriction, and circulatory instability. Consequently, patients with ACLF frequently experience diuretic intolerance and are at elevated risk for severe complications, including electrolyte disturbances, acute kidney injury (AKI), and hepatorenal syndrome (HRS). Current management strategies rely heavily on diuretics and albumin; however, the efficacy of diuretics is often limited by systemic hypotension and pre-existing renal impairment, leading to frequent treatment failure or diuretic-induced complications. Existing clinical guidelines lack definitive recommendations regarding the preemptive use of vasoconstrictors to stabilize hemodynamics before ascites becomes refractory. Midodrine, an oral alpha-1 adrenergic agonist, targets this circulatory dysfunction by increasing systemic vascular resistance and improving renal perfusion. This randomized controlled trial aims to evaluate the efficacy and safety of the early initiation of midodrine in achieving better control of ascites and preventing the progression to renal complications in patients with acute-on-chronic liver failure.

Feasibility Pilot Study to Evaluate the Safety and Performance of the MEX-CD1 Medical Device in ACLF

The goal of this clinical trial is to test the MEX-CD1 hemodialysis medical device in patients suffering from ACLF. The main questions it aims to answer are: * Is the device safe when used according to the instructions for use? * Does the device work as expected by removing the excess of free iron from the blood? Patients will receive 3 MEX-CD1 Slow Low volume CVVHD within 1 week.

Efficacy and Safety of Continuous Infusion of Terlipressin vs Bolus Terlipressin in ACLF Patients With Acute Esophageal Variceal Bleed

Acute portal hypertension, as measured by rapid rise in hepatic venous pressure gradient (HVPG) can lead to further dreaded complications, including acute variceal bleeding (AVB) AVB: 6-week mortality rates of around 15-20% in patients with chronic liver disease without ACLF.The overall prevalence of UGH in cirrhotic patients with AD was 34.4% and 35.7% in patients with ACLF.AVB is a well-recognized precipitant leading to the occurrence and development of ACLF. AVB is a well-recognized precipitant leading to the occurrence and development of ACLF. Medical therapy for esophageal variceal bleeding (EVB) aims to reduce the splanchnic blood flow and portal pressure. The most common vasoactive agents include terlipressin, vasopressin, somatostatin, and octreotide.

Goal Directed Ammonia Lowering Therapy in Hyperammonemic ACLF Patients With no Overt HE to Reduce Major Adverse Liver Related Outcomes (GOAL Trial)

SIRS in ACLF exacerbate adverse effects of ammonia - sarcopenia, infections, immune dysfunction, HE and organ dysfunction Persistent or incident hyperammonemia during first week of hospitalization in patients with ACLF is associated with increased risk of organ failure and death. Prospective studies on the efficacy of ammonia lowering therapies on major adverse liver related outcomes (MALO) (any of AARC III, bacterial infection, overt HE grade or death) in hyperammonemic ACLF patients with no overt HE are limited. In this study we aim to to compare the safety and efficacy of ammonia lowering therapy (goal directed lactulose and rifaximin) compared to SMT to prevent major liver related outcomes (MALO) (any of AARC III, bacterial infection, overt HE grade or death) in hyperammonemic ACLF patients with no overt HE.

Safety and Efficacy of Continuous Infusion of Terlipressin With Norepinephrine Versus Norepinephrine Alone in Improving Outcomes of Acute Kidney Injury in Acute on Chronic Liver Failure With Septic Shock

ACLF is defined differently in APASL,EASL and AASLD.APASL talks of reversibility in ACLF as per its definition and constitution of Homogenous population with ACLF.The definition of ACLF as per APASL is an acute hepatic insult manifesting as jaundice (serum bilirubin ≥ 5 mg/dL (85 micromol/L) and coagulopathy (INR ≥ 1.5 or prothrombin activity \< 40%) complicated within 4 weeks by clinical ascites and/or encephalopathy in a patient with previously diagnosed or undiagnosed chronic liver disease/cirrhosis, and is associated with a high 28-day mortality. At the onset of septic shock there is initially an increased secretion of Arginine vasopressin. However, this initial rise is short lasting, and the vasopressin levels come back to normal or low serum levels with continued hypotension. However, even normal levels are too low for the degree of hypotension in septic shock. This causes a relative deficiency of vasopressin in septic shock. The exact time when this fall happens is not known and it is likely to be variable. Vasopressin was therefore tried as an agent in septic shock. Terlipressin is a synthetic analogue of vasopressin. It has a greater selectivity for the V1 receptor. Currently, Norepinephrine is recommended as the first vasopressor to be started in general in septic shock population.(3) Catecholamines are the clinically used vasopressor agents of choice for supporting arterial blood pressure and ensuring adequate organ perfusion. Development of adrenergic hyposensitivity with loss of catecholamine presser effects is seen in advanced stages of Vasodilatory Shock. Progressively increasing catecholamine therapy frequently enters into a vicious cycle of major adverse side effects resulting in continuous clinical deterioration necessitating further catecholamine excess.

An Open-label Randomized Controlled Trial Comparing the Role of Therapeutic Plasma-exchange in Ameliorating Secondary Organ Dysfunctions in Patients With ACLF and Develop Biomarkers of Treatment Response

Rationale: Current understanding of the pathophysiology of ACLF suggests that unresolved injury, poor infection control, and liver regeneration result in persistent systemic inflammation and cytokine storm, which subsequently lead to systemic inflammatory response syndrome (SIRS) resulting in multiple organ failures, septic shock and deaths in ACLF. Nearly 74% of ACLF patients initially diagnosed without SIRS, sepsis, or organ failure developed SIRS by day 7 which increases the onset of secondary organ failure and sepsis with high short-term mortality. The emerging use of plasma exchange has shown some potential benefits in terms of dampening systemic inflammation and improvement of outcomes in some ACLF patients. However, there is currently no randomized controlled trial exploring the potential role in ameliorating secondary organ dysfunctions in patients with ACLF is not known. Hence in the current objective, we want to study the role of plasma exchange in the management of sec. organ failure in ACLF patients in a randomized controlled trial and identify the biomarker to access the treatment response to therapy.
