RESUMO

BACKGROUND AND AIMS: Risk stratification after cure from hepatitis C virus (HCV) infection remains a clinical challenge. We investigated the predictive value of noninvasive surrogates of portal hypertension (liver stiffness measurement [LSM] by vibration-controlled transient elastography and von Willebrand factor/platelet count ratio [VITRO]) for development of hepatic decompensation and hepatocellular carcinoma in patients with pretreatment advanced chronic liver disease (ACLD) who achieved HCV cure. APPROACH AND RESULTS: A total of 276 patients with pretreatment ACLD and information on pretreatment and posttreatment follow-up (FU)-LSM and FU-VITRO were followed for a median of 36.6 months after the end of interferon-free therapy. FU-LSM (area under the receiver operating characteristic curve [AUROC]: 0.875 [95% confidence interval [CI]: 0.796-0.954]) and FU-VITRO (AUROC: 0.925 [95% CI: 0.874-0.977]) showed an excellent predictive performance for hepatic decompensation. Both parameters provided incremental information and were significantly associated with hepatic decompensation in adjusted models. A previously proposed combined approach (FU-LSM < 12.4 kPa and/or FU-VITRO < 0.95) to rule out clinically significant portal hypertension (CSPH, hepatic venous pressure gradient ≥10 mm Hg) at FU assigned most (57.3%) of the patients to the low-risk group; none of these patients developed hepatic decompensation. In contrast, in patients in whom FU-CSPH was ruled in (FU-LSM > 25.3 kPa and/or FU-VITRO > 3.3; 25.0% of patients), the risk of hepatic decompensation at 3 years following treatment was high (17.4%). Patients within the diagnostic gray-zone for FU-CSPH (17.8% of patients) had a very low risk of hepatic decompensation during FU (2.6%). The prognostic value of this algorithm was validated in an internal (n = 86) and external (n = 162) cohort. CONCLUSION: FU-LSM/FU-VITRO are strongly and independently predictive of posttreatment hepatic decompensation in HCV-induced ACLD. An algorithm combining these noninvasive markers not only rules in or rules out FU-CSPH, but also identifies populations at negligible versus high risk for hepatic decompensation. FU-LSM/FU-VITRO are readily accessible and enable risk stratification after sustained virological response, and thus facilitate personalized management.

RESUMO

BACKGROUND: We conducted a prospective study using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-MRI) to determine whether sustained virological response (SVR) by direct-acting anti-viral (DAA) drugs suppresses hepatocarcinogenesis in patients with hepatitis C virus (HCV) infection. AIM: To use serial Gd-EOB-MRI to assess the impact of DAAs on hepatocarcinogenesis. METHODS: Between February 2008 and December 2018, 1083 consecutive patients with HCV infection underwent Gd-EOB-MRI. Of these, 719 patients were enrolled, including 210 patients in the 'Non-DAA group', who did not receive DAAs before the introduction of DAAs, and 509 patients in the 'DAA group', who achieved SVR after the introduction of DDAs. Factors associated with hepatocarcinogenesis were analysed by a Cox proportional hazard model. In addition, hepatocarcinogenesis was classified into two types, 'multistep' and 'de novo', on the basis of Gd-EOB-MRI findings. Factors associated with each type were analysed by Fine and Gray proportional hazards models. RESULTS: Hepatocarcinogenesis was observed in 67 of 719 (9.3%) patients. Factors associated with hepatocarcinogenesis were male gender, albumin-bilirubin (ALBI) grade 2 or 3, Lens culinaris agglutinin-reactive fraction of alpha-fetoprotein (AFP-L3) ≥5%, the presence of nonhypervascular hypointense nodules (NHHNs) and Non-DAA group. Of 67 patients, multistep hepatocarcinogenesis occurred in 58 patients (86.6%) and de novo hepatocarcinogenesis occurred in nine patients (13.4%). Factors associated with multistep hepatocarcinogenesis were male gender and Non-DAA group. CONCLUSION: The eradication of HCV by DAA therapy reduces multistep hepatocarcinogenesis.

RESUMO

OBJECTIVE: To determine the diagnostic accuracy of Doppler ultrasonography in predicting presence of esophageal varices in patients with hepatitis-C induced cirrhosis. STUDY DESIGN: Descriptive analytical study. PLACE AND DURATION OF STUDY: Department of Radiology, Jinnah Hospital, Lahore, from May 2016 to October 2016. METHODOLOGY: Patients aged 15-70 years, who presented with cirrhosis and proved to be cirrhosis caused by Hepatitis-C of any gender and duration of disease more than 6 months, were included. Patients with hepatocelullar carcinoma or portal vein thrombosis, having received treatment for esophageal varices, and unwilling to undergo endoscopy were excluded. All the patients then underwent Doppler ultrasonography to calculate splenoportal index and findings were correlated with endoscopy findings. RESULTS: Out of 200 patients, 137 (68.50%) were males and 63 (31.50%) were females. In Doppler ultrasonography positive patients, 113 were true positive and 8 were false positive. Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of Doppler ultrasonography in predicting presence of esophageal varices was 88.98%, 89.04%, 93.00%, 82.28% and 89.00%, respectively. CONCLUSION: Doppler ultrasonography is the non-invasive modality of choice with high diagnostic accuracy in predicting presence of esophageal varices in hepatitis-C induced cirrhosis.

RESUMO

RNA viruses represent a major global health threat, and the visualization of their RNA genome in infected cells is essential for virological research and clinical diagnosis. Due to the lack of chemical toolkits for the live-cell imaging of viral RNA genomes, especially native viral genomes without labeling and genetic modification, studies on native virus infection at the single-live-cell level are challenging. Herein, taking hepatitis C virus (HCV) as a representative RNA virus, we propose that the innate noncanonical G-quadruplex (G4) structure of viral RNA can serve as a specific imaging target and report a new benzothiazole-based G4-targeted fluorescence light-up probe, ThT-NE, for the direct visualization of the native RNA genome of HCV in living host cells. We demonstrate the use of the ThT-NE probe for several previously intractable applications, including the sensitive detection of individual virus-infected cells by small-molecule staining, real-time monitoring of the subcellular distribution of the viral RNA genome in live cells, and continuous live-cell tracking of the infection and propagation of clinically isolated native HCV. The fluorogenic-probe-based viral RNA light-up system opens up a promising chemical strategy for cutting-edge live-cell viral analysis, providing a potentially powerful tool for viral biology, medical diagnosis, and drug development.

RESUMO

BACKGROUND: Paritaprevir inhibits organic anion-transporting polypeptide (OATP)1B1 and OATP1B3, which transport bilirubin. Hyperbilirubinemia is an adverse event reported during hepatitis C treatment. Gadoxetic acid is also transported by OATP1B1/1B3. We evaluated whether the enhancement effect in gadoxetic acid-enhanced magnetic resonance (MR) imaging could predict the plasma concentration of paritaprevir and might anticipate the development of hyperbilirubinemia. METHODS: This prospective study evaluated 27 patients with hepatitis C who underwent gadoxetic acid-enhanced MR imaging prior to treatment with ombitasvir, paritaprevir, and ritonavir. The contrast enhancement index (CEI), a measure of liver enhancement during the hepatobiliary phase, was assessed. Plasma trough concentrations, and concentrations at 2, 4, and 6 h after dosing were determined 7 d after the start of treatment. RESULTS: Seven patients (26%) developed hyperbilirubinemia (≥ 1.6 mg/dl). Paritaprevir trough concentration (Ctrough) was significantly higher in patients with hyperbilirubinemia than in those without (p = 0.022). We found an inverse relationship between CEI and Ctrough (r = 0.612, p = 0.001), while there was not a significantly weak inverse relationship between AUC0-6 h and CEI (r = -0.338, p = 0.085). The partial correlation coefficient between CEI and Ctrough was -0.425 (p = 0.034), while excluding the effects of albumin and the FIB-4 index. Receiver operating characteristic (ROC) curve analysis showed that the CEI was relatively accurate in predicting hyperbilirubinemia, with area under the ROC of 0.882. Multivariate analysis showed that the CEI < 1.61 was the only independent predictor related to the development of hyperbilirubinemia, with an odds ratio of 9.08 (95% confidence interval 1.05-78.86, p = 0.046). CONCLUSIONS: Hepatic enhancement with gadoxetic acid was independently related to paritaprevir concentration and was an independent pretreatment factor in predicting hyperbilirubinemia. Gadoxetic acid-enhanced MR imaging can therefore be useful in determining the risk of paritaprevir-induced hyperbilirubinemia.

RESUMO

BACKGROUND: Little is known about the utility of transient elastography (TE) for assessing the prognosis of patients with decompensated cirrhosis (DC). METHODS: We analyzed HIV/HCV-coinfected patients with DC who underwent TE as part of their routine follow-up between 2006 and 2015. We also calculated the liver stiffness spleen diameter-to-platelet score (LSPS), FIB-4 index, albumin, MELD score, and Child-Pugh score. The primary outcome was death. RESULTS: The study population comprised 65 patients. After a median follow-up of 32 months after the first TE, 17 patients had received anti-HCV therapy and 31 patients had died. The highest area under the receiver operating characteristic curve (AUROC) value for prediction of death was observed with albumin (0.695), followed by Child-Pugh score (0.648), both with P values < .05. Lower AUROC values were observed with MELD score (0.633), TE (0.618), LSPS score (0.595), and FIB-4 (0.569), all with P values > .05. In the univariate Cox regression analysis, albumin, FIB-4, Child-Pugh score, and MELD score, but not TE, were associated with death. In the multivariate analysis, albumin and Child-Pugh score were the only baseline variables associated with death. CONCLUSIONS: Our results suggest that TE is not useful for assessing the prognosis of HIV-infected patients with decompensated HCV-related cirrhosis. Albumin concentration and Child-Pugh scores were the most consistent predictors of death in this population group.

RESUMO

OBJECTIVE: To determine the accuracy of shear-wave elastography (SWE) to differentiate low from advanced degrees of liver fibrosis in hepatitis C patients. MATERIAL & METHOD: Consented native/transplant hepatitis C patients underwent SWE using a C1-6 MHz transducer before ultrasound (US)-guided liver biopsy. Five interpretable SWE samples were obtained from the right lobe of the liver immediately before US-guided random biopsy of the right lobe. Average kilopascal (kPa) values were compared to the meta-analysis of histological data in viral hepatitis (METAVIR) fibrosis grading. SWE values were correlated with the degree of inflammation and fatty infiltration. RESULTS: Study population consisted of 115 patients (63 with transplant, and 52 with native liver) including 29 women and 86 men, with a mean ± SD age of 56 ± 8.7 years. Mean ± SD SWE values were 7.9 ± 3 kPa in 83 patients with METAVIR scores of 0-2 and 13.2 ± 5.9 kPa in 32 patients with METAVIR scores of 3 or 4 (P < .001). Area under curve (AUC) of a Receiver Operating Characteristics curve for advanced degrees of fibrosis was 0.81 (95% CI: 0.71, 0.90) (P < .001). AUCs of transplant versus native livers (0.78 [CI:0.62, 0.94] versus 0.85 [CI: 0.73, 0.96]), degree of inflammation (0.81 [CI: 0.65, 0.97] versus 0.72 [0.56, 0.88]), or degree of fat deposition (0.81 [CI:0.70, 0.92] versus 0.80 [CI:0.61, 1]) were not statistically different (P > .05). for kPa threshold of SWE value of 10.67 kPa to differentiate advanced from low degree of fibrosis had a sensitivity of 59% (CI: 41%-76%) and specificity of 90% (CI: 82%-96%). CONCLUSION: Liver stiffness evaluated by SWE can differentiate low from advanced liver fibrosis.

RESUMO

BACKGROUND & AIMS: We investigated the correlation between histological characteristics and changes in liver stiffness (LS) in patients with sustained virological response (SVR) using acoustic radiation force impulse (ARFI) elastography. METHODS: In this prospective study, we enrolled 176 hepatitis C patients with SVR who underwent ARFI elastography and liver biopsy before antiviral treatment, and serial ARFI elastography at the end of treatment (EOT) and at 24 weeks after the EOT. To compare the long-term changes in LS in patients with SVR using ARFI elastography, another group of 140 patients who had undergone paired biopsy after achieving SVR was included. RESULTS: Mean LS values were 1.60±0.63 m/s, 1.48±0.56 m/s and 1.37±0.62 m/s at baseline, EOT and 24 weeks after EOT, respectively, P<.001. Higher inflammatory activity at baseline was associated with an improvement in LS at the EOT, with an odds ratio of 1.940. Significant fibrosis at baseline was associated with an improvement in LS at 24 weeks after the EOT, with an odds ratio of 2.617. Among patients in the paired biopsy group with baseline fibrosis stage identical to the ARFI group, LS values at 24 weeks after the EOT did not show any difference with values at 5 years after EOT. CONCLUSIONS: Pre-treatment histological characteristics influence LS reduction after SVR is achieved.

RESUMO

With the widespread use of gadoxetic acid-enhanced magnetic resonance imaging, liver nodules appearing as hypovascular in the arterial phase and hypointense in the hepatobiliary phase, defined as hypovascular hypointense nodules, are increasingly detected in patients with cirrhosis and are considered precursor nodules. We sought to evaluate the interval to vascularization development in hepatitis C virus/hepatitis B virus co-infected-associated precursor nodules (BC-HHN group) compared with that in hepatitis C virus mono-infected-associated precursor nodules (C-HHN group) in the hepatobiliary phase of gadoxetic acid-enhanced magnetic resonance imaging. The interval to vascularization development was estimated by the Kaplan-Meier method and compared using the Cox proportional hazards model. The mean intervals to vascularization development in the BC-HHN and C-HHN groups were 272.9±31.1 and 603.8±47.6 days, respectively (p<0.001). The cumulative vascularization development incidence at 6, 12, and 18 months was 44.9%, 73.5%, and 91.8%, respectively, in the BC-HHN group and 16.9%, 39.0%, and 55.8%, respectively, in the C-HHN group (p<0.001). The multivariate analysis showed that the presence of hepatitis B virus co-infection (hazard ratio: 1.819; 95% confidence interval: 1.222-2.707; p = 0.003) and male sex (hazard ratio: 1.753; 95% confidence interval: 1.029-2.985; p = 0.039) were predictors of vascularization development. More than half of the hypovascular hypointense nodules showed high-signal changes on T2-weighted imaging, and almost half of them showed restricted diffusion on diffusion-weighted images, but these did not predict vascularization development. In a hepatitis C virus- and hepatitis B virus-endemic area, such as Taiwan, precursor nodules in the BC-HHN group tended to have shorter intervals to vascularization development, especially in male patients.

RESUMO

PURPOSE: To study liver 31P MRS, histology, transient elastography, and liver function tests in patients with virus C hepatitis (HCV) or autoimmune hepatitis (AIH) to test the hypothesis that 31P MR metabolic profile of these diseases differ. MATERIALS AND METHODS: 25 patients with HCV (n=12) or AIH (n=13) underwent proton decoupled 31P MRS spectroscopy performed on a 3.0T MR imager. Intensities of phosphomonoesters (PME) of phosphoethanolamine (PE) and phosphocholine (PC), phosphodiesters (PDE) of glycerophosphoethanolamine (GPE) and glycerophosphocholine (GPC), and γ, α and ß resonances of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH) were determined. Liver stiffness was measured by transient elastography. Inflammation and fibrosis were staged according to METAVIR from biopsy samples. Activities of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALT) and thromboplastin time (TT) were determined from serum samples. RESULTS: PME had a stronger correlation with AST (z=1.73, p=0.04) and ALT (z=1.77, p=0.04) in HCV than in AIH patients. PME, PME/PDE, PE/GPE correlated positively and PDE negatively with inflammatory activity. PE, PC and PME correlated positively with liver function tests. CONCLUSION: 31P-MRS suggests a more serious liver damage in HCV than in AIH with similar histopathological findings. 31P-MRS is more sensitive in detecting inflammation than fibrosis in the liver.

RESUMO

RATIONALE: Ectopic splenic autotransplantation refers to the heterotopic autotransplantation of splenic tissue and no treatment is necessary for it when patient is asymptomatic. Its incidence rate is reported up to 67% among patients with a history of splenic trauma and splenic surgery. The diagnosis of it before operation is really difficult, and it is easy to mimic as other tumors. PATIENT CONCERNS: We reported a 42-year-old man with hepatic splenosis, with history of splenectomy for traumatic splenic rupture 16 years ago and hepatitis B&C. The patient was enrolled with recurrent low back pain for more than 1 month without any treatment. DIAGNOSES: Radiological imaging revealed a subcapsular hepatic nodule, showing "fast-in and fast-out" enhancement. Surgery was performed, and the result of histological diagnosis was hepatic splenosis. INTERVENTIONS: No intervention before segmentectomy of the liver. LESSONS: When imaging of a patient with history of traumatic splenic rupture or splenectomy shows1 or few well circumscribed hepatic nodules with enhancement in dynamic study, we should suspect hepatic splenosis, for the purpose of avoiding unnecessary surgery.

RESUMO

ABSTRACT Background and rationale. Many different non-invasive methods have been studied with the purpose of staging liver fibrosis. The objective of this study was verifying if transient elastography is superior to aspartate aminotransferase to platelet ratio index for staging fibrosis in patients with chronic hepatitis C. Material and methods. A systematic review with meta-analysis of studies which evaluated both non-invasive tests and used biopsy as the reference standard was performed. A random-effects model was used, anticipating heterogeneity among studies. Diagnostic odds ratio was the main effect measure, and summary receiver operating characteristic curves were created. A sensitivity analysis was planned, in which the meta-analysis would be repeated excluding each study at a time. Results. Eight studies were included in the meta-analysis. Regarding the prediction of significant fibrosis, transient elastography and aspartate aminotransferase to platelet ratio index had diagnostic odds ratios of 11.70 (95% confidence interval = 7.13-19.21) and 8.56 (95% confidence interval = 4.90-14.94) respectively. Concerning the prediction of cirrhosis, transient elastography and aspartate aminotransferase to platelet ratio index had diagnostic odds ratios of 66.49 (95% confidence interval = 23.71- 186.48) and 7.47 (95% confidence interval = 4.88-11.43) respectively. Conclusion. In conclusion, there was no evidence of significant superiority of transient elastography over aspartate aminotransferase to platelet ratio index regarding the prediction of significant fibrosis, but the former proved to be better than the latter concerning prediction of cirrhosis.

CONCLUSION: In conclusion, there was no evidence of significant superiority of transient elastography over aspartate aminotransferase to platelet ratio index regarding the prediction of significant fibrosis, but the former proved to be better than the latter concerning prediction of cirrhosis.

RESUMO

OBJECTIVES: To clarify the correlation between hepatobiliary phase (HBP) images using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) and albumin-bilirubin (ALBI) grading system. MATERIALS AND METHODS: We evaluated 220 consecutive patients who underwent liver magnetic resonance imaging with Gd-EOB-DTPA. Quantitative liver-spleen contrast ratio (Q-LSC) was calculated in HBP images approximately 20min after Gd-EOB-DTPA administration. To evaluate the degree of association between Q-LSC and ALBI grade, the Child-Pugh (C-P) score was used for comparison. Correlation coefficients were calculated, and median Q-LSC values were compared with the C-P scores and ALBI grades. The Steel-Dwass multiple comparison test was used for statistical analysis. RESULTS: The correlation coefficient between Q-LSC and C-P score was -0.35, P<0.0001, and the ALBI grade was -0.61, P<0.0001. Q-LSC of overall median, C-P A, B, and C were 1.94, 1.91, 1.96, and 1.33, respectively. The differences between C-P A and C-P B, C-P B and C-P C, and C-P A and C-P C were P=0.999, 0.126, and 0.149, respectively. Q-LSC of the overall median, ALBI grade 1, 2, and 3 were 1.94, 2.12, 1.69, and 1.30, respectively. The differences between ALBI grades 1 and 2, 2 and 3, and 1 and 3 were P<0.0001, P=0.0466, and P=0.0035, respectively. Q-LSC was better correlated and discriminated by ALBI grade than C-P score. CONCLUSION: A strong correlation was observed between Q-LSC of an HBP image with Gd-EOB-DTPA and ALBI grade; HBP imaging could be a surrogate for the ALBI grade.

RESUMO

PURPOSE: To evaluate the usefulness of magnetic resonance elastography (MRE) in detecting the clinical progression of cirrhosis from Child-Pugh class A to B in patients with hepatitis C. MATERIALS AND METHODS: We reviewed the data of 101 consecutive patients with type C viral hepatitis and clinically suspected cirrhosis who fulfilled the all following criteria: available MRE at 1.5 Tesla (T) or 3.0T and laboratory tests within a month, Child-Pugh class A, platelet count less than 155 × 10(3) /µL, no clinical history of hepatocellular carcinoma, and ≥6 months of follow-up after MRE. We longitudinally analyzed the incidence of cirrhosis progression as defined by the clinical progression from Child-Pugh class A to B at two subsequent follow-up points. Risk of cirrhosis progression was assessed by Cox analyses and Kaplan-Meyer methods. RESULTS: Cirrhosis progression was noted in 25 patients during the follow-up period. Liver stiffness (hazard ratio [HR] by 1 kPa increase = 1.397; P = 0.0074), Child-Pugh score of 6 versus score 5 (HR of 3.085; P = 0.0276), and treatment responses to anti-viral therapy versus nonresponse (HR of <0.001, P = 0.0006) were independent risk factors of cirrhosis progression. The 1-year risk (0.7%; 95% confidence interval, 0.1-4.2%) of cirrhosis progression was negligible in patients with liver stiffness of <3.3 kPa or response to anti-viral treatment. CONCLUSION: MRE is useful to stratify the risk of cirrhosis progression in patients with hepatitis C. J. Magn. Reson. Imaging 2016;44:715-722.
