Three Japanese adolescents with chronic hepatitis C were treated by direct‐acting antivirals (DAAs). No adverse events or laboratory abnormalities were observed during and after DAA therapy, and a sustained virological response was achieved in all cases. The emotional functioning of the patients and their mothers were improved after DAA therapy. Key Clinical Message: The efficacy/safety of therapy with direct‐acting antivirals for chronic hepatitis C in Japanese adolescents were favorable and the improvement of emotional functioning of them and their mothers by viral eradication was observed in all cases.

Key Clinical Message: Atezolizumab and bevacizumab combination therapy might be one of the treatment options for hepatocellular carcinoma concurrent with gastric adenocarcinoma. [ABSTRACT FROM AUTHOR]

Noonan syndrome is a genetic multisystem disorder and is associated with mutation of genes encoding the proteins in the RAS‐MAPK pathway. We reported the first case of Noonan syndrome complicated with hepatocellular carcinoma. [ABSTRACT FROM AUTHOR]

Background: Sodium glucose cotransporter 2 (SGLT2) inhibitors are newly developed oral antidiabetic drugs. SGLT2 is primarily expressed in the kidneys and reabsorbs approximately 90% of the glucose filtered by the renal glomeruli. SGLT2 inhibitors lower glucose levels independently of insulin action by facilitating urinary glucose excretion. The SGLT2 inhibitor ipragliflozin has reportedly improved liver steatosis in animal models and clinical studies. However, the mechanisms by which SGLT2 inhibitors improve liver steatosis are not fully understood., Aim: To investigate the ameliorative effects of ipragliflozin on liver steatosis and the mechanisms of these effects in obese mice., Methods: We analyzed 8-wk-old male obese ( ob/ob ) mice that were randomly divided into a group receiving a normal chow diet and a group receiving a normal chow diet supplemented with ipragliflozin (3 mg/kg or 10 mg/kg) for 4 wk. We also analyzed their lean sex-matched littermates receiving a normal chow diet as another control group. Body weight and liver weight were evaluated, and liver histology, immunoblotting, and reverse transcription-polymerase chain reaction analyses were performed., Results: Hepatic lipid accumulation was significantly ameliorated in ob/ob mice treated with 10 mg/kg ipragliflozin compared to untreated ob/ob mice irrespective of body weight changes. Ipragliflozin had no appreciable effects on hepatic oxidative stress-related gene expression levels or macrophage infiltration, but significantly reduced hepatic interleukin-1β (IL-1β) mRNA expression levels. Ipragliflozin increased both the mRNA and protein expression levels of sirtuin 1 (SIRT1) in the liver. The hepatic mRNA levels of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), peroxisome proliferator-activated receptor α (PPARα), and fibroblast growth factor-21 (FGF21) were also significantly higher in ipragliflozin-treated ob/ob mice than in untreated ob/ob mice., Conclusion: Our study suggests that the liver steatosis-ameliorating effects of ipragliflozin in ob/ob mice may be mediated partly by hepatic SIRT1 signaling, possibly through the PGC-1α/PPARα-FGF21 pathway., (©The Author(s) 2020.
