Randomized Controlled Trial
A randomized placebo-controlled trial of prophylactic dexamethasone for transcatheter arterial chemoembolization.
This randomized, double-blind, placebo-controlled trial evaluated dexamethasone efficacy at preventing fever, anorexia, and nausea/vomiting, the most frequent adverse events of transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). Child-Pugh class A/B patients with HCC and no macrovascular invasion/extrahepatic metastases were randomly assigned to either a dexamethasone regimen (day 1, intravenous dexamethasone [20 mg] and granisetron [3 mg] before TACE; days 2 and 3, intravenous dexamethasone [8 mg]) or a control regimen (day 1, intravenous placebo [saline] and granisetron [3 mg]; days 2 and 3, intravenous placebo). The primary endpoint was complete response, defined as the absence of grade ≥1 fever, anorexia, or nausea/vomiting according to the Common Terminology Criteria for Adverse Events (version 4.0) and no use of rescue therapy for 120 hours after TACE. ⋯ Cumulative incidences of fever, anorexia, and nausea/vomiting were higher in the control regimen group compared with the dexamethasone group (P < 0.001, P < 0.001, and P = 0.095, respectively). The dexamethasone regimen was generally well tolerated by HCC patients including those with well-controlled diabetes mellitus and those with hepatitis B virus infection. Conclusion: The dexamethasone regimen was more effective than the control regimen at preventing TACE-induced fever, anorexia, and nausea/vomiting in patients with HCC. (Hepatology 2018;67:575-585).

Clinical guidelines recommend using Kidney Disease Improving Global Outcomes (KDIGO) criteria for the diagnosis and classification of acute kidney injury (AKI) in patients with chronic liver disease (CLD). Concerns have been raised about the use of urine output (UO) criteria in CLD. We examined the significance of oliguria meeting the urine output criteria for AKI (AKI-UO) and examined its association with clinical outcomes in CLD patients. ⋯ When only SC criteria were applied, 1281 (61%) of those patients with stage 2-3 AKI-UO were misclassified as either no AKI or AKI stage 1. Patients reclassified with AKI according to UO criteria (AKI-UO) had nearly a 3-fold increased rate of hospital mortality compared with patients without any AKI (14.6% versus 5%; P < 0.001) and more than a 50% increased mortality compared with stage 1 AKI-SC (14.6% versus 9%; P < 0.001). Patients with transient oliguria (AKI-UO stage 1) had increased mortality rates compared with patients without oliguria (14.9% versus 6.9%; P < 0.001).

Review Meta Analysis Comparative Study
Comparison of laboratory tests, ultrasound, or magnetic resonance elastography to detect fibrosis in patients with nonalcoholic fatty liver disease: A meta-analysis.
Many noninvasive methods for diagnosing liver fibrosis (LF) have been proposed. To determine the best method for diagnosing LF in nonalcoholic fatty liver disease (NAFLD), we conducted a systemic review and meta-analysis to compare the performance of aspartate aminotransferase to platelets ratio index (APRI), fibrosis-4 index (FIB-4), BARD score, NAFLD fibrosis score (NFS), FibroScan, shear wave elastography (SWE), and magnetic resonance elastography (MRE) for diagnosing LF in NAFLD. We compared the sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUROC) of these noninvasive methods for detecting significant fibrosis (SF), advanced fibrosis (AF), and cirrhosis. ⋯ With a FIB-4 threshold of 2.67 and 3.25, the sensitivities and specificities were 26.6% and 96.5% and 31.8% and 96.0%, respectively, for AF. The summary sensitivities and specificities of BARD score (threshold of 2), NFS (threshold of -1.455), FibroScan M (threshold of 8.7-9), SWE, and MRE for detecting AF were 0.76 and 0.61, 0.72 and 0.70, 0.87 and 0.79, 0.90 and 0.93, and 0.84 and 0.90, respectively. The summary AUROC values using APRI, FIB-4, BARD score, NFS, FibroScan M probe, XL probe, SWE, and MRE for diagnosing AF were 0.77, 0.84, 0.76, 0.84, 0.88, 0.85, 0.95, and 0.96, respectively.

Multicenter Study Observational Study
Magnetic resonance elastography measured shear stiffness as a biomarker of fibrosis in pediatric nonalcoholic fatty liver disease.
Magnetic resonance elastography (MRE) is a promising technique for noninvasive assessment of fibrosis, a major determinant of outcome in nonalcoholic fatty liver disease (NAFLD). However, data in children are limited. The purpose of this study was to determine the accuracy of MRE for the detection of fibrosis and advanced fibrosis in children with NAFLD and to assess agreement between manual and novel automated reading methods. ⋯ All three analyses were significantly correlated with fibrosis stage (center 1, ρ = 0.53; center 2, ρ = 0.55; and automated analysis, ρ = 0.52; P < 0.001). Overall cross-validated accuracy for detecting any fibrosis was 72.2% for all methods (95% confidence interval [CI], 61.8%-81.1%). Overall cross-validated accuracy for assessing advanced fibrosis was 88.9% (95% CI, 80.5%-94.5%) for center 1, 90.0% (95% CI, 81.9%-95.3%) for center 2, and 86.7% (95% CI, 77.9%-92.9%) for automated analysis.

Antiplatelet therapy has shown protective effects against hepatocellular carcinoma (HCC) in preclinical studies. However, it is unclear whether antiplatelet therapy lowers the risk of HCC in patients with chronic hepatitis B. A retrospective analysis was conducted of data from 1,674 chronic hepatitis B patients, enrolled between January 2002 and May 2015, whose serum hepatitis B virus DNA levels were suppressed by antivirals to <2,000 IU/mL. ⋯ In propensity score-matched pairs, antiplatelet therapy significantly reduced the risk of HCC (HR, 0.34; 95% CI, 0.15-0.77; P = 0.01). However, the overall risk of bleeding was higher in the antiplatelet group (HR, 3.28; 95% CI, 1.98-5.42; P < 0.001), particularly for clopidogrel with or without aspirin. Treatment with aspirin alone was not associated with a higher bleeding risk (HR, 1.11; 95% CI, 0.48-2.54; P = 0.81).
