RATIONALE: Invasive pulmonary aspergillosis is associated with significant morbidity and mortality in patients with liver failure. Voriconazole (VRCZ) is recommended as a primary therapeutic agent for the treatment of invasive aspergillosis and metabolized in the liver. Now, data are still lacking on the safety and appropriate dosage of VRCZ in patients with liver failure. Here, we report a representative case of invasive pulmonary fungal infection in a patient with liver failure who was treated with low-dose VRCZ...

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is often difficult to diagnose because bacteria in ascites cannot be detected accurately by conventional culture. In situ hybridization (ISH) was previously developed for rapid detection of genes from bacteria phagocytized by neutrophils. SBP may develop after bacteria enter into the systemic circulation following bacterial translocation. Therefore, we performed ISH to identify bacteria in blood samples collected from patients with decompensated liver cirrhosis (LC)...

Hepatocytes represent an important target for gene therapy and editing of single-gene disorders. In α-1 antitrypsin (AAT) deficiency, one missense mutation results in impaired secretion of AAT. In most patients, lung damage occurs due to a lack of AAT-mediated protection of lung elastin from neutrophil elastase. In some patients, accumulation of misfolded PiZ mutant AAT protein triggers hepatocyte injury, leading to inflammation and cirrhosis. We hypothesized that correcting the Z mutant defect in hepatocytes would confer a selective advantage for repopulation of hepatocytes within an intact liver...

Although nano- and microparticle therapeutics have been studied for a range of drug delivery applications, the presence of these particles in blood flow may have considerable and understudied consequences to circulating leukocytes, especially neutrophils, which are the largest human leukocyte population. The objective of this work was to establish if particulate drug carriers in circulation interfere with normal neutrophil adhesion and migration. Circulating blood neutrophils in vivo were found to be capable of rapidly binding and sequestering injected carboxylate-modified particles of both 2 and 0...

Platelets interact with tumor cells and promote metastasis. The importance of platelets in post-transplant hepatocellular carcinoma (HCC) recurrence is unclear. Thus, we aimed to evaluate the association between preoperative platelet count and HCC recurrence after living donor liver transplantation. Of 359 recipients of livers from living donors for HCC, 209 of 240 patients who had preoperative platelet count ≤75 × 10(9) /L were matched with 97 of 119 patients who had preoperative platelet count >75 × 10(9) /L using propensity score matching, with an unfixed matching ratio based on factors such as tumor biology...

Notch signaling plays an emerging role in the regulation of immune cell development and function during inflammatory response. Activation of the ras homolog gene family, member A (RhoA)/Rho-associated protein kinase (ROCK) pathway promotes leukocyte accumulation in tissue injury. However, it remains unknown whether Notch signaling regulates RhoA/ROCK-mediated immune responses in liver ischemia and reperfusion injury (IRI). This study investigated intracellular signaling pathways regulated by Notch receptors in the IR-stressed liver and in vitro...

Autoimmune liver diseases, which include mainly autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, and the variant syndromes, are often associated with extrahepatic autoimmune diseases. However, the association with cutaneous diseases is less well described. In the present article, we provide a systematic literature review on skin manifestations linked to each of these four autoimmune liver diseases, excluding skin manifestations of systemic diseases. The association of autoimmune hepatitis with vitiligo is well known, with a particular striking association with type 2 autoimmune hepatitis, a condition occurring almost entirely in children and adolescents, much rarer and more aggressive than type 1 autoimmune hepatitis; probable associations are also identified with alopecia areata, psoriasis, and pyoderma gangrenosum...

Lipid nanoparticles (LNPs) are the leading technology for delivering short interfering RNA (siRNA) in vivo. While numerous attempts to improve the efficiency of siRNA delivery have been reported, only a few studies of the mechanism of LNP-mediated toxicity and attempts to develop safe LNPs in vivo have been reported, in spite of the significance of such systems, in the light of treatment and clinical applications. We herein report on the elucidation of the mechanism of hepatotoxicity following the intravenous injection of a high dose of hepatotropic LNPs...

AIM: Water retention, hepatic ascites, and peripheral edema are significant problems in patients with liver cirrhosis (LC). Although furosemide and spironolactone are commonly used as treatment, these are often insufficient to treat hyponatremia and renal insufficiency in patients with LC. Tolvaptan (TVP) could provide an effective treatment alternative. However, predictive factors of a therapeutic response to TVP are unclear. Our aim was to examine clinical predictors of the response to TVP in patients with LC and water retention...

Accumulating evidence suggests that IL-1β plays a pivotal role in the pathophysiology of hepatic ischemia-reperfusion (I/R) injury; however, the mechanism by which I/R triggers IL-1β production in the liver remains unclear. Recent data have shown that neutrophils contribute to hepatic I/R injury independently of the inflammasomes regulating IL-1β maturation. Thus, we investigated the role of neutrophils in IL-1β maturation and tissue injury in a murine model of hepatic I/R. IL-1β was released from the I/R liver and its deficiency reduced reactive oxygen species generation, apoptosis, and inflammatory responses, such as inflammatory cell infiltration and cytokine expression, thereby resulting in reduced tissue injury...

To date there is only one drug in use, praziquantel, to treat more than 250 million people afflicted with schistosomiasis, a debilitating parasitic disease. The aryl hydantoin Ro 13-3978 is a promising drug candidate with superior in vivo activity to praziquantel against both adult and juvenile Schistosoma mansoni Given the drugs' contrasting low activity in vitro, and the timing of its onset of action in vivo, it was postulated that immune-assisted parasite clearance could contribute to the drug's in vivo activity...

Alcoholic liver disease (ALD) is a leading cause of liver-related morbidity and mortality worldwide. There is no effective treatment to prevent the disease progression. Magnesium isoglycyrrhizinate (MgIG) showed potent anti-inflammatory, antioxidant, and hepatoprotective activities and was used for treating liver diseases in Asia. In this study, we examined whether MgIG could protect mice against alcohol-induced liver injury. The newly developed chronic plus binge ethanol feeding model was used to study the role of MgIG in ALD...
