Liver failure with hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome with high mortality. The aim of this study was to decipher clinical and laboratory characteristics of hemophagocytic lymphohistiocytosis after definite diagnosis of liver failure and to provide clues for early diagnosis and treatment of HLH in patients with liver failure. Eleven patients diagnosed with liver failure and HLH were retrospectively investigated in this study. All patients presented with jaundice, persistent high-grade fever, pancytopenia, splenomegaly, evidence of hemophagocytes in the bone marrow and laboratory abnormalities indicating HLH. The average interval from the earliest diagnosis of liver failure to a definitive diagnosis of HLH was 17.27 days. Six (54.55%) patients died during follow-up. For patients with liver failure after admission and subsequently definitively diagnosed with HLH, bilirubin and INR were significantly decreased. HLH is definitely diagnosed at an intermediate or late stage when patients have already suffered from liver failure. The initial dose of glucocorticoid (methylprednisolone) was decreased to 1–1.5 mg/kg/d and gradually reduced thereafter. In conclusion, for patients with liver failure, HLH should be screened as early as possible upon persistent fever, splenomegaly and unexplained pancytopenia. For patients with liver failure and HLH, the dosage of glucocorticoid should be reduced to avoid serious side effects.

Acute-on-chronic liver failure (ACLF) is a serious life-threatening disease with high prevalence. Liver transplantation is the only efficient clinical treatment for ACLF. Because of the rapid progression and lack of liver donors, it is urgent to find an effective and safe therapeutic approach to ACLF. Recent studies showed that multipotent cell transplantation could improve the patients' liver function and enhance their preoperative condition. Cells such as mesenchymal stem cells, bone marrow mononuclear cells and autologous peripheral blood stem cells, which addressed in this study have all been used in multipotent cell transplantation for liver diseases. However, its clinical efficiency is still debatable. This systematic review and meta-analysis explored the clinical efficiency of multipotent cell transplantation as a therapeutic approach for patients with ACLF. A detailed search of the Cochrane Library, MEDLINE, and Embase databases was conducted from inception to November 2017. The outcome measures were serum albumin, prothrombin time, alanine aminotransferase, total bilirubin, platelets, hemoglobin, white blood cells, and survival time. The quality of evidence was assessed using GRADEpro and Jaded scores. A literature search resulted in 537 citations. Of these, 9 articles met the inclusion criteria. It was found that multipotent cell transplantation was able to alleviate liver damage and improve liver function. Multipotent cell transplantation can also enhance the short-term and medium-term survival rates of ACLF. All 9 research articles included in this analysis reported no statistically significant adverse events, side effects, or complications. In conclusions, this study suggested that multipotent cell transplantation could be recommended as a potential therapeutic supplementary tool in clinical practice. However, clinical trials in large-volume centers still needed.

This study aimed to determine if the immunoscore (IS) staging system would be a potential prognostic factor in hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) in China. IS was performed in a consecutive cohort of HBV-HCC patients (n= 92). CD3+, CD8+, and CD45RO+ T cells were quantified by immunohistochemical analyses. The patients were stratified into 5 IS groups: I0, I1, I2, I3, I4 for every 2 cell phenotypes (IS1 (CD8/CD45RO, IS2 (CD3/CD8), and IS3 (CD3/CD45RO), respectively. ImagePro Plus software was used in the calculation of the paraffin-embedded tumor sections. The staining of CD3+, CD8+, and CD45RO+ cells in the HBV-HCC tissue demonstrated that there were higher density and larger area of lymphocytes in the invasive margins (IM) region than in the center (CT). Univariate analysis showed that preoperative TNM staging (P = .01), serum gamma-glutamyl transpeptidase (GGT) level (P = .03), vascular invasion (P = .00), and density of CD3+T (CT) (P = 0.01) were correlated significantly with disease-free survival (DFS); serum alpha-fetoprotein (AFP) level (P = .02), tumor size (P = .00), serum cholinesterase (CHE) (P = .04), and GGT level (P = .01), density of CD3+T(CT) (P = .00), CD8+T(CT)(P = .00), CD45RO+T(CT) (P = .00), and CD45RO+T (IM) (P = .02) were correlated with overall survival (OS). Multivariate analysis showed that TNM staging was not an independent prognostic factor of DFS and OS. Our results showed ISs did not have a significantly correlation with DFS (P = .35, .19, and .07, respectively), but it was correlated significantly with OS (P = .00, .00, and .00, respectively). There were statistical differences among the OS of every ISs subgroup except I0 and I1 by the Cox regressions analysis. The IS staging was closely related to the outcome of patients. It can compensate the TNM tumor classification system in predicting the prognosis of HBV-HCC patients.

MicroRNAs (miRNAs) represent a class of evolutionarily conserved, non-coding small RNAs (18–25 nt) that have emerged as master regulators of several biological processes. Recently, circulating miRNAs have also been reported to be promising biomarkers for various pathological conditions. In the present study, we report the comparative expression profiling of microRNA-101 (miR-101) in serum and tissue samples from chronic hepatitis B (CHB), HBV-associated liver cirrhosis (HBV-LC), and HBV-associated hepatocellular carcinoma (HBV-HCC) patients and healthy controls. The serum miR-101 levels were found to be significantly downregulated in the HBV-HCC patients compared with the HBV-LC patients (P < 0.001), CHB patients (P < 0.001) and healthy controls but were upregulated in the HBV-LC patients compared with the CHB patients (P < 0.001) and healthy controls (P < 0.001). Consistent with the serum data, the expression of miR-101 was also upregulated and downregulated in the HBV-LC and HBV-HCC tissue samples, respectively. A receiver operating characteristic (ROC) analysis of serum miR-101 yielded an area under the ROC curve (AUC) of 0.976 with 95.5% sensitivity and 90.2% specificity when differentiating between HBV-HCC and HBV-LC. Our results suggest that the serum miR-101 level can serve as a potential non-invasive biomarker to differentiate HBV-HCC from HBV-LC.
