Abstract
Urinary 8-oxo-7,8-dihydroguanosine (8-oxoGuo) and 8-oxo-7,8-dihydro-2'- deoxyguanosine (8-oxodGuo) are considered biomarkers of oxidative stress, and patients with nephrotic syndrome have been reported to have increased oxidative stress levels. In this study, we aimed to assess the value of 8-oxoGuo and 8-oxodGuo as novel biomarkers to evaluate the severity of nephrotic syndrome. In total, 107 patients with nephrotic syndrome and 116 healthy controls were recruited for this study. The concentrations of urinary 8-oxoGuo and 8-oxodGuo were measured using isotope-labeled liquid chromatography with tandem mass spectrometry. Urinary creatinine was used to regulate 8-oxoGuo and 8-oxodGuo concentrations. Urinary 8-oxoGuo and 8-oxoGuo/Cr levels in patients with nephrotic syndrome were significantly higher than those in healthy control participants. 8-oxoGuo/Cr showed a positive correlation with the 24 h urinary total protein (UTP) and UTP levels and negative correlations with serum total protein and albumin levels. After treatment, urinary 8-oxoGuo and 8-oxoGuo/Cr levels were significantly lower in the group with a low 24 h-UTP value (<3.5 g/d) than in the high value group. 8-oxoGuo can be used as a feasible and reliable biomarker for the assessment of nephrotic syndrome.HighlightsUrinary 8-oxoGuo level was significantly increased in patients with nephrotic syndrome.Urinary 8-oxoGuo level increased with an increase in plasma protein and a decrease in urine protein.Urinary 8-oxoGuo level decreased with nephrotic syndrome remission when urinary microalbumin showed no significant change.Urinary 8-oxoGuo level can be used as novel biomarkers of nephrotic syndrome.

Abstract
Amyloidosis causes various symptoms in many organs of the body, but amyloidosis that presents with liver damage alone has never been reported. We treated an 83-year-old man with amyloidosis who presented with liver damage alone. The liver damage in this patient was histologically proven to be liver amyloidosis. The administration of bortezomib and dexamethasone was not effective, so he rapidly died of liver failure. An aggressive liver biopsy should be considered when unexplained jaundice is observed.

Abstract
Although hepatic involvement in light chain–associated amyloidosis is common, clinical manifestations of hepatic amyloidosis are rare. In most cases, hepatomegaly serves as a clue to diagnosis. We report a unique case of a 48-year-old man from China with jaundice and noncirrhotic portal hypertension, with rapidly progressive liver failure, in the absence of hepatomegaly, secondary to systemic light chain–associated amyloidosis associated with multiple myeloma.

Abstract
Amyloid light chain (AL) amyloidosis is a disease of misfolded, fibrous proteins, either kappa or lambda subtype, that can be deposited into one or more organs, caused by a proliferation of plasma cells. The liver is uncommonly the main organ system affected and rarely the only organ affected by amyloid deposition. With hepatic involvement, the most common presenting findings are hepatomegaly and elevation of serum alkaline phosphatase. We report a case of a 50-year-old male who presented to our gastroenterology clinic with marked hepatomegaly secondary to hepatic amyloidosis, in concert with bone marrow involvement and nephrotic syndrome. Biopsies in conjunction with Congo red staining demonstrated 95% replacement of hepatic structure and 80% replacement of bone marrow with amyloid deposition. Despite these findings, liver chemistries, renal function, and blood count were normal. Our case presents not only the rare finding of primary hepatic amyloidosis but also an atypical presentation of this disorder. Although rare, AL amyloidosis should be in a differential diagnosis of any patient who presents with unexplained hepatomegaly, nephrotic-range proteinuria, heart failure with preserved ejection fraction, fatigue, weight loss or a history of monoclonal gammopathy of undetermined significance.

Abstract
This research utilized an external longitudinal dataset of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) to compare and validate various predictive models that support the current recommendations to select the most effective predictive risk models to estimate short- and long-term mortality and facilitate decision-making about preferable therapeutics for HBV-ACLF patients. Twelve ACLF prognostic models were developed after a systematic literature search using the longitudinal data of 232 HBV-ACLF patients on the waiting list for liver transplantation (LT). Four statistical measures, the constant (A) and slope (B) of the fitted line, the area under the curve (C) and the net benefit (D), were calculated to assess and compare the calibration, discrimination and clinical usefulness of the 12 predictive models. According to the model calibration and discrimination, the logistic regression models (LRM2) and the United Kingdom model of end-stage liver disease(UKELD) were selected as the best predictive models for both 3-month and 5-year outcomes. The decision curve summarizes the benefits of intervention relative to the costs of unnecessary treatment. After the comprehensive validation and comparison of the currently used models, LRM2 was confirmed as a markedly effective prognostic model for LT-free HBV-ACLF patients for assisting targeted and standardized therapeutic decisions.
