Filter by:It has been identified that impaired liver function, as occurs in patients with liver cirrhosis, prevents proper conjugation of glucuronic acid with bilirubin; as a result, unconjugated bilirubin accumulates in the blood, and conjugated bilirubin is markedly altered to form diglucuronides or monoglucuronides. However, in the development and progress of acute-on-chronic liver failure (ACLF) there is not enough information about these processes and the possible concentration levels that they can take. Also Hepatic encephalopathy (HE) is a reversible complication, but with a high mortality rate in patients with acute or chronic liver failure, as well as a consequence of the formation of portosystemic shunts.
Patients with cirrhosis patients have a high incidence of sepsis which can trigger decompensation and may result in prolonged hospital stay and increased mortality. About 30%-50% admissions of patients with cirrhosis have sepsis at presentation and about 15% patients admitted to hospital develop sepsis during the hospital stay . After infection develops, the patient may develop acute kidney injury (AKI), shock, encephalopathy or disseminated intravascular coagulation (DIC) further decreasing the chances of survival. In fact, sepsis in patients with cirrhosis is associated with 15% in-hospital mortality, approximately double that of patients without sepsis. So, sepsis is directly responsible for 30-50% of deaths in cirrhosis . Therefore, it is critical to manage sepsis early and appropriately in cirrhosis to reduce the complications and mortality. Early administration of fluids, source control and empirical antibiotics along with vasopressors if refractory shock are essential components of treatment in all patients with sepsis. Currently, the most accepted strategy for early sepsis management is a combination of early goal directed therapy (EGDT) and physiological parameters, such as urine output, lactate clearance, and administration of antibiotics, within 1 hour of presentation . The use of central venous pressure assessment is fallacious for gauging adequacy of fluid resuscitation in cirrhosis, and the difficulty of performing echocardiographic assessments in the setting of ascites and cirrhotic cardiomyopathy is also well described .
There is very little data related to the natural history of disease from covert HE (MHE and grade 1 HE) to overt HE (grades II, III and IV) in ACLF, with implications on long-term neurological recovery after an episode of overt HE. The evolution and pathogenesis of HE is well described in ALF and cirrhosis, but the dynamic changes in HE in ACLF in response to therapy such as ammonia reduction measures, antibiotics to target sepsis and inflammation, measures to alter dysbiosis such as probiotics or fecal microbiota transplant, and measures to target immune dysfunction such as steroids in alcohol-associated hepatitis. The central role of ammonia in the pathogenesis of HE in ACLF has been challenged by recent data. The approach to HE in ACLF has now refocused on systemic and neuro-inflammation, gut dysbiosis, immune dysregulation, and multi-omics approach. Most importantly, the modulation of the metabolome in response to therapy and interventions, and the use of sedatives, paralytic agents, antibiotics etc. in ACLF with HE in a real-world setting has not been reported.
Patients with Acute on Chronic Liver Failure (ACLF) have high short-term mortality. The use of a severity score could define the patient's prognosis. This study mainly prospectively analyze the clinical data of patients with chronic liver disease related acute liver failure admitted to the department of infectious diseases, Xiangya Hospital of Central South University, to analyze the prognosis of patients with chronic liver disease related acute on-chronic liver failure in Central South China. No additional interventions other than routine treatment will be added.
This study aims to investigate the efficacy and safety of avatrombopag for treating thrombocytopenia in hepatitis b virus related acute-on-chronic liver failure patients receiving artificial liver support system treatment.
Various parameters will be assessed during the procedure before and after 1 hour of 12.5 mg carvedilol such as HVPG (WHVP - FHVP), SVR, heart rate, cardiac output, cardiac index, Blood pressure (systolic, diastolic and mean), SpO2. Routine treatment of the patients will be continued as per the Institute protocol. These patients will be assessed for the liver transplant free survival at 28 days and complications [PHT related bleed, AKI, infections, HE] within 90 days; transplant-free survival rate at 90 days; evolution of the AARC score for 2 wk.
Registry intended to provide a data repository and reporting infrastructure for the surveillance of CytoSorb device use in real-world critical care settings, and to serve as an objective, comprehensive, and scientifically-based resource to measure and improve the quality of patient care
In this project, we plan to evaluate whether a new, rotational thromboelastometry-guided algorithm (ROTEM) to guide hemostatic resuscitation decreases the use of allogeneic blood products, the total amount of bleeding, transfusion related side effects, thromboembolic complications and costs. Its effect on each patient's post-operative hemostatic profile is also measured. We plan to enroll 140 patients having ACLF with variceal bleeding randomized into two groups: one will be treated conventionally using clinical judgement and standard coagulation tests such as prothrombin time, platelet count, etc. the other treated using a ROTEM-based algorithm. They will be followed for development of rebleeding, complications of transfusion and any signs of infection after hospitalization
In critically ill patients with liver disease like cirrhosis or ACLF, fluid therapy needs to be instituted after identification of patients who will be fluid responsive and initiate appropriate inotropes early to prevent the mortality associated with fluid overload. The parameters and methodology used for assessing fluid responsiveness have been studied earlier, but the optimum method is not established. Existing recommendations based on data regarding fluid responsiveness and choice of fluid for resuscitation from intensive care units in general cannot be applied to those with liver disease as the hemodynamic alterations that occur with liver disease, presence of hypoalbuminemia at baseline and presence of cardiac dysfunction interfere with the conventional methods of fluid status assessment, fluid responsiveness as well as the response to different types of resuscitation fluids. Therefore the investigators attempt to compare various methods to estimate current intravascular volume status of patient which could be helpful in guiding fluid therapy.
Acute liver failure patients posed high mortality rate despite receiving standard therapy. The severity and mortality even higher in patients with underlying liver disease. Acute liver failure cause hyperinflammatory response in early stage and immunoparalysis in later stage. The surge of proinflammatory cytokines leads to multiorgan failure and more liver injury. Subsequent immunoparalysis may lead to lethal secondary infections. Liver support system had been used in acute and acute ontop chronic liver disease for last several decades. Double plasma molecular adsorption system (DPMAS) is one of the promising non-biological liver support system that have been extensively investigated in acute ontop chronic liver failure from hepatits B viral. DPMAS circuit consist of BS330 (bilirubin adsorber) and HA330 (Cytokines adsorber). Thus, DPMAS can also remove various cytokines. The effect of DPMAS on immune function in these patients has not been explored. Recent randomized controlled trial by Srisawat et al. demonstrated improvement of mHLA-DR in septic shock patients who received polymyxin B extracorporeal therapy compare to control arm. Since liver failure show change of immunological profile resemble to sepsis. Investigators proposed that removal of toxic liver toxins and lethal cytokines by DPMAS will improve immunological profiles in acute ontop chronic liver failure patients. Investigators plan to conduct a randomized controlled trial in acute ontop chronic liver failure patients who admitted to intensive care unit. Investigators plan to compare the immunomodulatory effects of DPMAS with standard treatments.
