IntroductionIn advanced chronic liver disease, diseases caused by common bacteriaStreptococcus pneumoniaeor influenza virus put people at an increased risk of serious health complications and death. The effectiveness of the available vaccines in reducing the risk of poor health outcomes, however, is less clear.Methods and analysisWe will search Medline (Ovid), Embase (Ovid), PubMed and Cochrane Central Register of Controlled Trials for published reports on randomised controlled trials and observational studies on the effectiveness of pneumococcal and influenza vaccines in people with chronic liver disease. Two independent reviewers will screen the studies for eligibility, extract data and assess study quality and risk of bias. Random effects meta-analyses will be performed as appropriate.Ethics and disseminationFormal ethical approval is not required, as no primary data will be collected for this study. We will publish results of this study in relevant peer-reviewed medical journal or journals. Where possible, the study results will also be presented as posters or talks at relevant medical conferences and meetings.PROSPERO registration numberCRD42017067277.

IntroductionUse of albumin therapy is recommended for management of disease complications in cirrhosis. The effectiveness of albumin to prevent specific disease complications and death, however, is less clear.Methods and analysisWe will search Medline (Ovid), Embase (Ovid), Cochrane Hepato-Biliary Controlled Trials Register and Cochrane Central Register of Controlled Trials for published reports on randomised controlled trials and observational studies on the effectiveness of intravenous albumin therapy to prevent spontaneous bacterial peritonitis, renal dysfunction and death in cirrhotic patients. Two independent reviewers will screen the studies for eligibility, extract data and assess risk of bias and quality of evidence using Grading of Recommendations Assessment, Development and Evaluation system. Random effects meta-analyses will be performed when appropriate.Ethics and disseminationAs no primary data will be collected, a formal ethical approval is not required. We plan to publish the results of this study in a relevant peer-reviewed journal or journals. The study results may also be presented at relevant conferences and meetings.PROSPERO registration numberCRD42018100798.

Abstract Background People living with human immunodeficiency virus (PLWH) are at increased risk of cirrhosis and esophageal varices. Baveno VI criteria, based on liver stiffness measurement (LSM) and platelet count, have been proposed to avoid unnecessary esophagogastroduodenoscopy (EGD) screening for esophageal varices needing treatment (EVNT). This approach has not been validated in PLWH. Methods PLWH from 8 prospective cohorts were included if they fulfilled the following criteria: (1) compensated advanced chronic liver disease (LSM >10 kPa); (2) availability of EGD within 6 months of reliable LSM. Baveno VI (LSM <20 kPa and platelets >150 000/μL), expanded Baveno VI (LSM <25 kPa and platelets >110 000/μL), and Estudio de las Hepatitis Víricas (HEPAVIR) criteria (LSM <21 kPa) were applied to identify patients not requiring EGD screening. Criteria optimization was based on the percentage of EGDs spared, while keeping the risk of missing EVNT <5%. Results Five hundred seven PLWH were divided into a training (n = 318) and a validation set (n = 189). EVNT were found in 7.5%. In the training set, Baveno VI, expanded Baveno VI, and HEPAVIR criteria spared 10.1%, 25.5%, and 28% of EGDs, while missing 0%, 1.2%, and 2.2% of EVNT, respectively. The best thresholds to rule out EVNT were platelets >110 000/μL and LSM <30 kPa (HIV cirrhosis criteria), with 34.6% of EGDs spared and 0% EVNT missed. In the validation set, HEPAVIR and HIV cirrhosis criteria spared 54% and 48.7% of EGDs, while missing 4.9% and 2.2% EVNT, respectively. Conclusions Baveno VI criteria can be extended to HEPAVIR and HIV cirrhosis criteria while sparing a significant number of EGDs, thus improving resource utilization for PLWH with compensated advanced chronic liver disease.

In this commentary to the paper by Donadon V. et al (Clinical Medicine: Endocrinology and Diabetes. 2009;2:25–33.) the association and significance of insulin resistance with chronic liver disease are shortly reviewed and the molecular mechanisms underlying the diabetogenic and oncogenic potentials of advanced liver disease are summarized. Literature studies demonstrate that hepatocellular carcinoma (HCC) can be part of the natural history of NASH. HCCs in patients with features of metabolic syndrome as the only risk factor for liver disease have distinct morphological characteristics and mainly occur in the absence of significant fibrosis in the background liver. Moreover, data indicate that the presence of diabetes carries an approximately three to four-fold increased risk of HCC and such a risk is strongly increased by concurrent viral infections. Finally, the relationship between insulin resistance, steatosis and diabetes in NAFLD and HCV infection will be commented, along with the directions for future studies.
