Management of coagulopathy among patients with cirrhosis undergoing upper endoscopy and paracentesis: Persistent gaps and areas of consensus in a multispecialty Delphi.

Patients with cirrhosis have abnormal coagulation indices such as a high international normalized ratio and low platelet count, but these do not correlate well with periprocedural bleeding risk. We sought to develop a consensus among the multiple stakeholders in cirrhosis care to inform process measures that can help improve the quality of the periprocedural management of coagulopathy in cirrhosis. We identified candidate process measures for periprocedural coagulopathy management in multiple contexts relating to the performance of paracentesis and upper endoscopy. An 11-member panel with content expertise was convened. It included nominees from professional societies for interventional radiology, transfusion medicine, and anesthesia as well as representatives from hematology, emergency medicine, transplant surgery, and community practice. Each measure was evaluated for agreement using a modified Delphi approach (3 rounds of rating) to define the final set of measures. Out of 286 possible measures, 33 measures made the final set. International normalized ratio testing was not required for diagnostic or therapeutic paracentesis as well as diagnostic endoscopy. Plasma transfusion should be avoided for all paracenteses and diagnostic endoscopy. No consensus was achieved for these items in therapeutic intent or emergent endoscopy. The risks of prophylactic platelet transfusions exceed their benefits for outpatient diagnostic paracentesis and diagnostic endosopies. For the other procedures examined, the risks outweigh benefits when platelet count is >20,000/mm 3 . It is uncertain whether risks outweigh benefits below 20,000/mm 3 in other contexts. No consensus was achieved on whether it was permissible to continue or stop systemic anticoagulation. Continuous aspirin was permissible for each procedure. Clopidogrel was permissible for diagnostic and therapeutic paracentesis and diagnostic endoscopy. We found many areas of consensus that may serve as a foundation for a common set of practice metrics for the periprocedural management of coagulopathy in cirrhosis.

Discovery of Half-life of Circulating Hepatitis B Surface Antigen in Patients With Chronic Hepatitis B Infection Using Heavy Water Labeling.

In a pilot study, heavy water labeling was used to determine hepatitis B surface antigen (HBsAg) turnover rates in chronic hepatitis B (CHB) patients. The mean (standard deviation) half-life of HBsAg in blood was 6.7 (5.5) days, which reflects recent production in the liver and supports strategies aimed at reducing HBsAg production in CHB patients.

Treatment of hepatitis C with direct-acting antivirals significantly reduces liver-related hospitalizations in patients with cirrhosis.

BACKGROUND: The availability of direct-acting antivirals (DAA) for the treatment of hepatitis C (HCV) has resulted in the ability to safely and effectively treat patients with cirrhosis and end-stage liver disease. However, information is limited with regard to the impact of DAA treatment on inpatient health-related resource utilization in patients with advanced HCV-related cirrhosis. We aimed to ascertain the impact of DAA treatment on the frequency of liver-related hospitalizations and associated costs in patients with cirrhosis. PATIENTS AND METHODS: Retrospective cohort analysis carried out at a single US reference center that compared patients with HCV cirrhosis according to treatment status: the untreated group (January 2011 to December 2013) and the DAA-treated group (January 2014 to March 2017). The primary outcome was the difference in the incidence rate of liver-related hospitalizations. Secondary outcomes included differences in the incidence of hepatocellular carcinoma, liver transplant, and all-cause mortality. We calculated the projected savings per-patient treated per-year on the basis of calculated hospitalization rate stratified by Child-Turquotte-Pugh (CTP) score. RESULTS: Baseline characteristics were similar between the untreated (n=182) and DAA-treated (n=196) cohorts. Mean follow-up time in the untreated and treated cohort was 20.4 and 17.7 months, respectively. The incidence rates of liver-related hospitalizations were 29.1/100 and 10.4/100 person-years of follow-up (P≤0.0001) in the untreated and treated cohorts, respectively. This was accounted for by a decreased incidence of hospitalizations in patients with CTP-A (75.8%) and CTP-B (64.5%), but not CTP-C. CONCLUSION: Successful DAA treatment reduces hospitalization rate and resource utilization costs in patients with CTP-A and CTP-B, but not in those with CTP-C.
