Besides, while gentamicin downregulated and cefazolin sodium upregulated Gr gene expression, amoxicillin did not alter it. Protein expression was only affected by the administration of cefazolin sodium in the kidney. This study is important as it demonstrates that while amoxicillin and gentamicin showed parallel effects on the GR activity in liver and kidney tissues both in vitro and in vivo, cefazolin sodium had a very strong effect on hepatic and renal GR in vivo. Furthermore, the antibiotics used in this study induced oxidative stress in both tissues. © 2020 Wiley Periodicals, Inc.Antithymocyte globulin is a major drug in transplantation. rATG has been successfully used to prevent graft-versus-host disease in allogeneic HSCT. However, its first infusion is associated with reactions ranging from simple fevers to distributive shocks and may interfere with the transplant conditioning. To evaluate the impact of rATG infusion rate on clinical tolerability, we conducted a retrospective study of all pediatric allogeneic HSCT patients who received rATG (Thymoglobulin®) as part of their conditioning at Lille University Hospital from 2003 to 2018. Until 2012, patients received rATG with a theoretical infusion time of 12 hours (12H group, n = 33). From 2012, they had a theoretical infusion time of 4 hours (4H group, n = 43). Patients from the 12H arm presented more ≥ grade 3 infusion-related reactions at first dose (70% versus 44%, P = .027), had significantly higher fever (median of 39.6°C versus 39.2°C, P = .002), and needed a greater use of symptomatic treatments. However, they received a slightly higher first dose of rATG (median of 2.7 versus 2.3 mg/kg, P = .042). In view of these results, a rATG infusion time of 4 hours can be a relevant option for pediatric transplant centers to avoid interference with the conditioning regimen and facilitate medical surveillance. © 2020 Wiley Periodicals, Inc.We red with great interest the article of Wang et al. about the usage of plateletcrit (PCT) for the predictionof liver fibrosis in patients with chronic hepatitis B.1 According to the results, the authors claimed that PCT was an independent predictor of significant liver fibrosis, and it might be used as an alternative technique to diagnose liver fibrosis.

While liver damage in classic acute hepatitis B is believed to be T-cell mediated, the pathogenesis of HBV-associated ALF remains largely unknown. Access to liver specimens from well-characterized patients with HBV-associated ALF provided us with the opportunity to perform next-generation sequencing (NGS) of the entire VH repertoires of IgM and IgG from the livers of four ALF patients, a control liver donor and a patient with chronic HBV infection. We found that ALF is not associated with expansion of specific B-cell lineages. However, NGS showed that the intrahepatic VH repertoires from ALF patients were characterized by the abundant presence of antibodies in germline configuration in contrast to their marginal prevalence in controls. Moreover, NGS identified a large number of VH genes in germline configuration with identical VDJ sequences in the IgM and IgG repertoires in all four ALF patients, indicating that isotype switch from IgM to IgG had occurred without somatic hypermutation. The results of this study indicate that the presence of intrahepatic antibodies in unmutated germline configuration is a broad phenomenon in the global antibody repertoire generated from total RNA derived from whole-liver tissue that is strongly associated with ALF, suggesting a major role of T cell-independent humoral immunity in the pathogenesis of ALF. © 2020 John Wiley & S
