Abstract
BACKGROUND New direct acting antiviral agent (DAA) therapies are associated with a high sustained virological response rate (SVR) in hepatitis C virus (HCV) patients. The understanding of the impact of SVR on fibrosis stage is limited. OBJECTIVES To determine the effect of treatment with the DAAs on long-term liver fibrosis stages, as determined by shear-wave elastography (SWE) or FibroTest. METHODS Fibrosis stage was determined at baseline and at 6-month intervals after end of treatment (EOT), using two-dimensional SWE or FibroTest©; APRI and FIB-4 scores. RESULTS The study comprised 133 SVR12 patients. After a median follow-up of 15 months (range 6-33), liver fibrosis stage decreased by at least 1 stage in 75/133 patients (56%). Cirrhosis reversal was observed in 24/82 (29%). Repeated median liver stiffness SWE values in cirrhotic patients were 15.1 kPa at baseline (range 10.5-100), 13.4 kPa (range 5.5-51) at 6 months, and 11.4 kPa (range 6.1-35.8) at 12 months after EOT, P = 0.01. During the second year after EOT, no statistically significant differences in liver fibrosis stage in 12, 18, and 24 months were found. Splenomegaly was the only significant negative predictor of liver fibrosis regression during all time points of repetitive noninvasive assessment. CONCLUSIONS Following successful DAA treatment, the majority of our HCV patients with advanced fibrosis demonstrated significant improvement, as assessed by non-invasive methods. Advanced fibrosis stage was a negative predictor of fibrosis regression. Longer follow-up periods are required to further establish the impact of DAAs treatment in HCV patients with advanced fibrosis.

Abstract
BACKGROUND Point shear-wave elastography (pSWE) is a new method to assess the degree of liver fibrosis. It has been shown to be effective in detecting stiffness in viral hepatitis. OBJECTIVES To determine the feasibility of pSWE for assessing liver stiffness and fibrosis in liver diseases of different etiologies. METHODS This prospective single-center study included a population of adult patients with chronic liver diseases from different etiologies, who were scheduled for liver biopsy, and a control group of healthy adults who prospectively underwent pSWE. Ten consecutive pSWE measurements of the liver were performed using a Philips iU22 ultrasound system. Stiffness degree was compared to liver biopsy results. Fibrosis degree was staged according to METAVIR scoring system. RESULTS The study group was comprised of 202 patients who underwent liver biopsy and pSWE test and a control group consisting of 14 healthy adults who underwent pSWE for validation. In the study group, the median stiffness was 5.35 ± 3.37 kilopascal (kPa). The median stiffness for F0-1, F2, F3, and F4 as determined by liver biopsy results were 4.9 kPa, 5.4 kPa, 5.7 kPa, and 8 kPa, respectively. The median stiffness in the control group was 3.7 ± 0.6 kPa. Subgroup analyses were conducted for viral hepatitis vs. non-viral hepatitis and steatohepatitis vs. non-steatohepatitis groups. CONCLUSIONS pSWE is a reproducible method for assessing liver stiffness and is in a linear relationship with fibrosis degree as seen in pathology. Compared with patients with non-significant fibrosis, healthy controls showed significantly lower values.

Role of Doppler Ultrasound Combined With Clinical Features in the Diagnosis of Transjugular Intrahepatic Portosystemic Shunt Dysfunction in the Era of Covered Stents. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2020; 39:2373-2377. [PMID: 32468705 DOI: 10.1002/jum.15346] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Revised: 04/29/2020] [Accepted: 05/03/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVES Our goal was to discuss the role of Doppler ultrasound (US), combined with clinical features, in the diagnosis of transjugular intrahepatic portosystemic shunt (TIPS) dysfunction in the era of covered stents. In light of the lack of research regarding the accuracy of Doppler US in TIPS dysfunction evaluations when using covered stents and a recent major meta-analysis, which primarily reviewed studies with bare metal stents but few with covered stents, we aimed to provide our single-center case study for further investigation. METHODS All patients from 2010 to 2019 who underwent angiography for a covered stent preceded by a Doppler US examination in our institution were retrospectively reviewed. RESULTS All of the Doppler US and angiographic examination results showed complete agreement, and 11 of 12 were positive for TIPS dysfunction. CONCLUSIONS Combining the presence of positive clinical signs for TIPS dysfunction with Doppler US may increase its accuracy. Considering our results, there may be a need to reinvestigate Doppler US as a noninvasive, inexpensive, and available tool for the diagnosis of TIPS dysfunction in the era of covered stents, despite recent publications depicting Doppler US as inadequate for evaluating a TIPS.

Alterations of the salivary and fecal microbiome in patients with primary sclerosing cholangitis. Hepatol Int 2020; 15:191-201. [PMID: 32949377 DOI: 10.1007/s12072-020-10089-z] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 08/26/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is a chronic, progressive liver disease known for its frequent concurrence with inflammatory bowel disease. PSC can progress to cirrhosis, end-stage liver disease, hepatobiliary cancer, and/or colorectal cancer. The etiopathogenesis of PSC remains poorly understood, and, as such, pharmacotherapy has yet to be definitively established. Little is known about the salivary microbiome in PSC and PSC-IBD. This study aimed to evaluate the oral microbiome of patients with PSC, with association to these patient's fecal microbial composition. METHODS Saliva, fecal samples and Food Frequency Questionnaires were collected from 35 PSC patients with or without concomitant inflammatory bowel disease and 30 age- and BMI-matched healthy volunteers. 16S rRNA gene sequencing was performed using Illumina MiSeq platform. RESULTS The salivary microbial signature of PSC was significantly altered as compared to healthy controls, independent of concomitant IBD, and was comprised of 19 significantly altered species, of which, eight species were consistently overrepresented in both fecal and saliva of patients with PSC, including Veillonella, Scardovia and Streptococcus. CONCLUSIONS PSC is characterized by microbial dysbiosis in the gut and the salivary microbiome, independently from IBD. The PSC dysbiotic signature includes a reduction in autochthonous bacteria and an increased relative abundance of pathogenic bacteria, including an invasion of oral bacteria to the gut. PSC is a strong modulator of the microbial profile, in the gut and the oral microbiome. These results may lead to the development of biomarkers for screening and early diagnosis or the development of personalized medicine in PSC.

Abstract
Idiopathic hypereosinophilic syndrome (HES) is a rare, heterogeneous disorder characterized by a strikingly high eosinophil count (>1,500 cells/μL), over a long period of time (>6 months), with end organ damage. We present a 60-year-old patient with idiopathic HES with isolated liver involvement, a rare systemic disease and a rare solid organ involvement. The patient had a thorough investigational work up until HES was established, including liver biopsy. He needed intensive immunosuppressive treatment at first with steroids, then with azathioprine in conjunction with a low dose of steroids. After 16 years of follow-up, the patient showed no evidence of liver dysfunction. To the best of our knowledge, this is the longest follow-up for a patient with HES-associated chronic hepatitis. Our observation suggests that, with appropriate treatment, liver involvement in HES may be well controlled without deterioration to advanced liver failure.

Abstract
BACKGROUND Accurate assessment of liver fibrosis is crucial for the management of patients with hepatitis C virus (HCV) infection. OBJECTIVES To evaluate the performance of liver segment-to-spleen volume ratio in predicting the severity of liver fibrosis. METHODS Sixty-four consecutive HCV patients were enrolled in this retrospective study. All patients underwent contrast-enhanced computed tomography (CT) and were divided into three groups based on their hepatic fibrosis stage evaluated by shear-wave elastography (SWE): non-advanced (F0-F1, n=29), advanced (F2, n=19) and severe fibrosis (F3-F4, n=16). Using semi-automated liver segmentation software, we calculated the following liver segments and spleen volumes for each participant: total liver volume (TLV), caudate lobe (CV), left lateral segment (LLV), left medial segment (LMV), right lobe (RV) and spleen (SV), a well as their ratios: CV/SV, RV/SV, LLV/SV, LMV/SV and TLV/SV. RESULTS RV/SV was found to discriminate between patients with non-advanced and advanced fibrosis (P = 0.001), whereas SV, CV, RV, TLV/SV, LMV/SV and RV/SV discriminated between patients with advanced and severe fibrosis (P < 0.05). RV/SV ≤ 3.6 and RV ≤ 2.9 were identified as the best cutoff values to differentiate non-advanced from advanced fibrosis and advanced from severe fibrosis with sensitivities of 72.2% and 92.7%, specificities of 72.7% and 77.8%, and with an area under the receiver operating characteristic (ROC) curve of 0.797 and 0.847, respectively (P ≤ 0.002). CONCLUSIONS RV/SV may be used for the assessment and monitoring of liver fibrosis in HCV patients prior to the administration of antiviral therapy, considering SWE as the reference method.

Abstract
We report on a case of spontaneous bacterial peritonitis (SBP) due to Haemophilus influenzae (H. influenzae) in an elderly patient with alcoholic cirrhosis. The patient presented with a 5 day history of fever, cough, and fatigue. Abdominal paracentesis revealed a very high neutrophil count (134,800 cells/μL). Secondary peritonitis and abdominal abscess were ruled out. Peritoneal fluid culture displayed the growth of H. influenzae. The patient was treated with ceftriaxone and showed signs of improvement. Eventually, the patient died due to septic shock caused by other organisms. H. influenzae is a very rare cause of SBP. This case report demonstrates that (1) H. influenzae should be considered a potential cause of SBP, and (2) a very high leukocyte count in ascitic fluid can be found in patients with SBP.

Abstract
BACKGROUND AND AIM Recently, with the emergence of highly effective antiretroviral treatment (ART), chronic liver disease has become the leading cause of morbidity and mortality in co-infected HIV-HCV (Human immunodeficiency virus-Hepatitis C virus) patients. The overall SVR rate in this population remains unsatisfactory. The aim of this study was to evaluate the response to therapy in HIV-HCV co-infected patients in a single center. PATIENTS AND METHODS Consecutive HIV-HCV co-infected patients were evaluated in the liver clinic between 2003 -2010. Liver needle biopsy was conducted in 100% of the patients. The patients were treated by a multidisciplinary team consisting of immunologists, hepatologists, social workers and nurses and a close follow-up was conducted. The 48 weeks duration of peg-interferon and ribavirin combination was used for all genotypes according to recent guidelines. Weight-adjusted ribavirin doses were applied. Treatment was initiated after stabilization of HIV parameters and successful weaning from drug and alcohol addiction. RESULTS A total of 86 out of 143 HIV- HCV co-infected patients, were evaluated; 39 completed treatment. Of those 31 (77%) achieved SVR. Out of 22 genotype 1 patients, 18 (82%) achieved SVR. Six patients had spontaneous viral clearance and 8 are still receiving treatment. In 17 non-one genotype patients, the SVR rate was 76.4% (13 of 17 patients); 6 patients were defined as relapsers and non-responders. Overall adherence to the treatment was high. CONCLUSION Measures, such as the use of a multidisciplinary approach, high adherence of physicians to the guidelines, weight-based ribavirin dose, and selecting patients who are ready to start therapy, can significantly improve the SVR rate in this difficult-to-treat patient population.

Abstract
BACKGROUND AND AIMS Acute hepatitis C virus infection in the era of universal screening of blood products has not disappeared, and is thought to be transmitted primarily via injecting drug use. A growing body of evidence supports iatrogenic transmission as an important mode of transmission. The aim of this study was to examine transmission routes and clinical characteristics in a group of patients with acute hepatitis C in Israel. METHODS A retrospective chart review was conducted in three different liver clinics in Israel, of all new hepatitis C patients. Patients identified as possible acute hepatitis C were re-interviewed and all other sources such as blood bank records and pre-employment check-ups reviewed in order to establish the diagnosis of acute hepatitis C infection and to identify the transmission route. RESULTS Twenty-nine patients were found to have acute hepatitis C, representing 0.75% of all new referrals for hepatitis C. The most frequent (65%) mode of transmission was iatrogenic involving several, often minimal, procedures and clinical settings. The group in which iatrogenic transmission was suspected was older and the patients more often in monogamous relationship compared with other transmission routes groups. Injecting drug use was the second most common route of infection. Spontaneous seroconversion has occurred in approximately one third of the patients. CONCLUSIONS Acute hepatitis C in the post universal blood products screening era was found to be predominantly an iatrogenic disease in the investigated localities. This finding should direct attention and resources towards the development and implementation of preventive measures.

Abstract
PURPOSE To prospectively evaluate the accuracy of esophagography with barium in diagnosis of esophageal varices (EV) in patients with compensated cirrhosis, with endoscopic gastroduodenoscopy as the reference standard. MATERIALS AND METHODS In this study, which was approved by the local Helsinki Committee and in which all patients consented to participate, 61 patients with cirrhosis (34 men, 27 women; mean age, 61 years; range, 36-76 years) received a diagnosis clinically or with liver biopsy. In 87% (n = 53) of patients, Child-Pugh classification was A; in 13% (n = 8), Child-Pugh classification was B. They were evaluated with endoscopic gastroduodenoscopy, according to Japanese general criteria. Esophagography was performed within 3 weeks of endoscopic gastroduodenoscopy, and EV were assigned grades as follows: 0, no EV were seen; 1, EV manifested as very mild irregularities of the folds; and 2, the irregularity of the folds (EV) was clearly present. They were also assigned grades for shape and size: grade F0, no EV detected; grade F1, small straight EV; grade F2, slightly enlarged tortuous EV occupying less than one-third of esophageal lumen; and grade F3, large coil-shaped EV that occupied more than one-third of esophageal lumen. The sensitivity and specificity and positive and negative predictive values of esophagography for identification of each grade of EV were calculated separately, as was the 95% confidence interval. RESULTS All large EV (grades F2 and F3) were diagnosed at esophagography. Sensitivity declined with small EV (grade F1) to 71. The overall sensitivity of esophagography was 89% (95% confidence interval: 75.9%, 96.5%), the overall specificity was 83% (95% confidence interval: 64.5%, 94.7%), the overall positive predictive value was 89%, and the overall negative predictive value was 83% (95% confidence interval: 64.5%, 94.7%). Overall accuracy was 87%. CONCLUSION Esophagography is highly accurate in diagnosis of EV and can be considered a viable noninvasive alternative for determination of patients who should be selected for prophylactic treatment.

Abstract
AIM To assist in tissue characterisation for the non-invasive diagnosis of diffuse fatty liver infiltration by providing quantitative indices of ultrasonic (US) backscatter with correlation to histology. METHODS AND MATERIALS US images from patients referred to US-guided liver needle biopsy (LNB) for persistently elevated liver enzymes or serologically positive markers for viral hepatitis were recorded. The histopathological reports were reviewed. Steatosis, inflammation and degree of fibrosis were scored from 0 (normal) to 3 (severe). Patients with level 3 steatosis without inflammation or fibrosis were selected. US images from twenty-four healthy subjects served as control. Four textural indices were calculated for a selected ROI corresponding to the biopsy site. Sensitivity and specificity of discrimination between the two groups were evaluated. RESULTS Fatty and healthy livers formed two distinct clusters. However, in all parametric subspaces there was a slight overlap between the groups with a few numbers of cases located across the dichotomy line.The sensitivity for all the indices was high (90 - 100 %). The specificity for each of the indices was moderate. The co-occurrence local homogeneity index yielded the highest specificity (88.5 %), with a sensitivity equivalent to two of the other indices (90 %). CONCLUSIONS Highly accurate "ultrasonic biopsy" may be obtained for severe fatty liver. The described indices can serve as a tool in US computer- aided diagnosis (CAD) of diffuse parenchymal liver disease, in particular for severe steatosis of the liver.

Abstract
The objective of this study was to compare textural to attenuation/backscatter indices of fatty liver correlated to histology to suggest the better approach for an objective noninvasive ultrasonic "biopsy". Forty-four patients with severe steatosis by histopathology were selected for this study. Ten patients had "pure" fatty liver and 34 had in addition fibrosis and/or inflammation. Ultrasonic images were acquired before needle insertion. The ROI used for biopsy was marked on the ultrasonic image and characterized by three attenuation/backscatter and 18 textural related indices. Statistical analysis was performed using logistic regression. Twenty-one healthy subjects served as control. The attenuation/backscatter indices were superior to textural indices in differentiating between the categories studied. Pure fatty livers could be reliably identified (AUC = 1, SE = 0). Among the 18 textural indices, "co-occurrences sum entropy" and "co-occurrences entropy" presented the best results. Attenuation/backscatter based indices appear to have better potential than the textural based indices.

Abstract
UNLABELLED Percutaneous needle liver biopsy is an important procedure for the diagnosis and evaluation of liver disease and is frequently associated with pain. In this prospective study, we investigated the prevalence and characteristics of this pain syndrome. Fifty-four subjects, who underwent liver biopsy under ultrasound guidance, received 5 mg of diazepam orally 1 h before the procedure and local infiltration with 10 mL of 2% lidocaine just before needle insertion. Outcome measures included the visual analog scale for measuring pain intensity over 24 h, pain localization on a body scheme, and the Spielberger questionnaire for measuring anxiety levels. Forty-seven (84%) of the 54 respondents reported pain 30 min after the biopsy (visual analog scale, 4.2 +/- 0.5; mean +/- SEM), and 21 (39%) reported pain at the 24-h time point. Biopsy site pain was reported by 9 subjects, right shoulder pain by 14, and pain at both sites by 24. Higher pain intensities were reported by women and by subjects with higher anxiety levels. This study indicates that liver biopsy is a painful condition in most patients. Mild anxiolytic treatment plus local anesthetic infiltration seem to produce insufficient analgesia, thus indicating that a more profound analgesic treatment is required for better control of this pain. IMPLICATIONS Percutaneous liver biopsy is a painful procedure in most patients. Mild anxiolytic treatment plus local anesthetic infiltration seem to produce insufficient analgesia. A more profound analgesic treatment is required for better control of this pain.
