Granulocyte colony stimulating factor in acute liver failure and alcoholic hepatitis

Randomized prospective study on the impact on the post-LT outcome by the infusion of N-acetylcysteine (NAC) during the liver procurement procedure, as an anti-oxidant agent to reduce the ischemia-reperfusion damage of organs for liver transplantation (LT).

Citrate has been proposed as anticoagulation of choice in continuous renal replacement therapy (CRRT). However, little is known about the pharmacokinetics (PKs) and metabolism of citrate in liver failure patients who require CRRT with regional citrate anticoagulation (RCA).

Major liver surgery is associated with increased incidence of perioperative complications and increased mortality if these are not addressed quickly in a high dependency intensive care unit. Of these, posthepatectomy liver failure (PHLF) represents one of the most important cause of postoperative unfavourable outcome. The present study investigates the correlation between lactate levels and PHLF. Lactate levels were collected at six specific timepoints: preoperative, pre-dissection phase, post-dissection phase, end of surgery and 24-hours and 48-hours in the postoperative period.

The purpose of this study is to collect clinical and epidemiological data as well as serum, plasma, urine, tissue and DNA samples on individuals who have acute liver failure and on individuals who have acute liver injury, a less severe group of patients who have coagulopathy but do not reach the threshold of encephalopathy.

Acute on chronic liver failure (ACLF) is a distinct entity encompassing the acute deterioration of liver function, culminating in multiple organs failure and high short-term mortality. Definitions and descriptions of ACLF vary between Western and Eastern types, and alcoholism and hepatitis B virus (HBV) are the main etiologies, respectively. To determine whether there are unified diagnostic criteria, severity classification and prognostic model for different etiologies of ACLF. Investigators had launched a multicenter prospective cohort with the same inclusion criteria and disease indicators as those used in the European CANONIC (Chronic liver failure-ACLF in Cirrhosis) study in China，the Ch-CANONIC study(NCT02457637). From Jan 2015 to Dec 2016, 2,600 inpatients with chronic liver disease complicated with ALI and/or AD were recruited. Data were collected during a 28-day hospitalization and continuous follow-ups were performed once a month until 36 months after hospitalization (at least 18 months up to now). Of these patients, 71.5% had HBV-related disease, 1833 had cirrhotic disease, and 767 had non-cirrhotic disease diagnosed by CT scan. Due to the lack of pathological gold standards, the diagnosis of ACLF is based on the clinical assessment of short-term mortality from organ functional parameters. In subsequent statistics and data analysis, investigators focused on (but not limit in) the relationship between short-term mortality and 6 parameters (bilirubin, INR, Creatinine, SpO2/FiO2, mean arterial pressure and West-Haven grade) from CLIF-C OFs (Chronic liver failure-Consortium Organ Failure score). And then a specific mathematical model has been constructed to obtain the available organ failure cutoff values. Subsequently, investigators carried out a diagnostical criteria for ACLF based on the results obtained from the model and get a good internal-validation result through risk ratio. Meanwhile, investigators conducted a precise prediction model for patients' prognosis and achieved a good predictive effect with consistency by AUC internal-validation. In addition, investigators summarized the course and some characteristics of ACLF. Therefore, investigators hope to launch another prospective multi-center cohort study with the same inclusion and exclusion criteria, and continue to recruit 800 to 900 patients (about 30% of the previous cohort) as the external validation cohort for the preliminary results mentioned above.

The purpose of the study is to describe patient characteristics and drug usage among patients that are prescribed ticagrelor for the first time and to compare them with patients who are prescribed clopidogrel and prasugrel for the first time. A further purpose is to ascertain and estimate the crude incidence rate of bleeding, arrhythmias, heart failure, acute renal failure, acute liver failure, dyspnoea and gout among new users in the three cohorts of ticagrelor, clopidogrel and prasugrel.

The PALF study group began with 20 sites and now continues with 12 sites (11 in the United States and 1 in Canada) in the new funding period. The primary objective of the Pediatric Acute Liver Failure (PALF) study is to collect, maintain, analyze, and report clinical, epidemiological, and outcome data in children with ALF, including information derived from biospecimens.

Hepatitis B accounts for approximately 5000 deaths per year in the United States. Liver transplantation offers the only hope for patients who develop end-stage liver disease. Early results of liver transplantation for hepatitis B were poor with recurrence rate of 80% and 1-year survival of only 50%. Recent studies found that preventive therapy using hepatitis B immune globulin (HBIG) or antiviral medications such as lamivudine can reduce the recurrence rate to roughly 30% with accompanying improvement in survival. However, HBIG when given as intravenous infusion in high doses is very expensive, while long-term use of lamivudine is associated with drug resistance. Some studies found that preventive therapy using both HBIG and lamivudine may decrease recurrence rate to less than 10% but the dose and duration of HBIG needed when used in combination with lamivudine is not clear. Adefovir, a new antiviral medication, is effective against lamivudine resistant hepatitis B but its role in liver transplantation is uncertain because of the risk of kidney damage. Many studies showed that the risk of recurrent hepatitis B is related to the viral load before transplant. Thus, it may be possible to tailor the preventive therapy according to the risk. The aim of this study is to establish the most cost-effective preventive therapy for recurrent hepatitis B after liver transplantation.
