Synergistic effects of Lactobacillus rhamnosus culture supernatant and bone marrow mesenchymal stem cells on the development of alcoholic steatohepatitis in mice.

In this study, a mouse model of chronic alcoholic hepatitis was established by eight weeks of Lieber-DeCarli liquid diet feeding; and LGG-s, BMMSCs or a combination of the two were used to explore a new therapeutic method for alcoholic liver disease and to study the mechanism. The results showed that the combined LGG-s and BMMSC treatment might have a synergistic effect and could improve the symptoms of alcoholic hepatitis by regulating inflammation, autophagy and lymphocyte subsets through the PI3k/NF-kB and PI3K/mTOR pathways. With the treatment, the autophagy rate accelerated, and alcohol-induced natural killer B (NKB) cell and follicular helper T (TFH) cell numbers decreased. These findings suggest that the development of alcoholic hepatitis may occur via PI3K/NF-kB and PI3K/mTOR pathway overactivation as well as through NKB and TFH cell imbalances. Moreover, LGG-s and BMMSCs can regulate these factors and alleviate the disease. PMID: 31632541 [PubMed]

Authors: Barcelos STA, Dall'Oglio VM, de Araújo A, Cerski CTS, Álvares-da-Silva MR Abstract Hepatic sinusoidal obstruction syndrome (HSOS) is a hepatic vascular disease histologically characterized by edema, necrosis, detachment of endothelial cells in small sinusoidal hepatic and interlobular veins and intrahepatic congestion, which leads to portal hypertension and liver dysfunction. In the Western world, most HSOS cases are associated with myeloablative pretreatment in a hematopoietic stem cell transplantation setting. Here we report a case of a 54 years old female patient, otherwise healthy, with n...

Conclusion Massive SI and immune cell paralysis associated with ACLF represent the extreme severity of CAID in response to an infectious or sterile challenge. The severe immune disturbance plays a pivotal role in the pathogenesis of the distinctive features of ACLF: organ failure and bacterial infection susceptibility. Excessive SI in ACLF results from the massive activation and dysfunction of an innate immune system challenged by increased PAMPs and DAMPs. SI leads to cell and tissue immunopathology contributing to hepatic and extrahepatic organ failure. Concomitantly, the course of ACLF is associated with a disproportio...

Conclusions: While there is a certain overlap between the results of the current study and published transcriptomic profiles of non-transplanted livers with steatosis, we have identified discrete characteristics of the non-alcoholic fatty liver disease in liver grafts potentially utilizable for the establishment of predictive signature. Introduction Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in industrialized countries, its prevalence being estimated at 19–31.3% (1). It encompasses a range of conditions that are thought to arise from fatty liver (simple steatosis) throu...

In humans, almost 50% of all intrahepatic lymphocytes are NK cells that are strongly imprinted in a liver-specific manner and show a broad spectrum of cellular heterogeneity. Hepatic NK (he-NK) cells play key roles in tuning liver immune response in b...

This article reviews the recent development in understanding alcohol-induced disruption of marrow granulopoiesis and the granulopoietic response with the focus on progress in delineating cell signaling mechanisms underlying the alcohol-induced injury to hematopoietic tissue. Efforts in exploring effective therapy to improve patient care in this field will also be discussed.

This study aims to determine whether granulocyte colony stimulating factor (G-CSF) treatment increases short-term survival in patients with severe AH refractory to corticosteroid treatment.Methods/designPatients with severe AH whose Maddrey ’s discriminant function (MDF) score is ≥ 32 and who will be treated with prednisolone (40 mg/day) for 1 week will be screened. Among them, 190 subjects with a partial response (PR) (Lille score 0.16–0.56), and 78 subjects with a null response (NR) (Lille score ≥ 0.56) will be enro lled. Subjects with PR will be randomized to steroid ...
