RESUMO
INTRODUCTION: Both transient elastography (TE)-based and non-TE-based criteria exist for detection of varices needing treatment (VNT) in patients with asymptomatic advanced chronic liver disease (CLD). However, their performance in clinical settings at different risk thresholds of detection of VNT and in regions where elastography is not widely available is unknown. We aimed to validate existing noninvasive criteria in our patients with CLD and identify best TE- and non-TE-based criteria for VNT screening at usual risk thresholds. METHODS: Patients with compensated advanced CLD (cACLD) who underwent esophagogastroduodenoscopy and TE within 3 months were included. Diagnostic performance of Baveno VI, expanded Baveno VI, platelet-model for end-stage liver disease, and platelet-albumin (Rete Sicilia Selezione Terapia-hepatitis C virus) criteria were estimated. Decision curve analysis was conducted for different predictors across range of threshold probabilities. A repeat analysis including all patients with compensated CLD (cACLD and non-cACLD) was performed to simulate absence of TE. RESULTS: A total of 1,657 patients (cACLD, 895; non-cACLD, 762) related to hepatitis B virus (38.2%), hepatitis C virus (33.4%), nonalcoholic steatohepatitis (14.7%), and alcohol (11.8%) were included. Baveno VI identified maximum VNT (97.3%) and had best negative predictive value (96.9%), followed by platelet-albumin criteria. Expanded Baveno VI and platelet-model for end-stage liver disease had intermediate performance. At threshold probability of 5%, Baveno VI criteria showed maximum net benefit, and platelet-albumin criteria was next best, with need for 95 additional elastographies to detect 1 additional VNT. Similar results were obtained on including all patients with compensated CLD irrespective of TE. DISCUSSION: Baveno VI criteria maximizes VNT yield at 5% threshold probability. An acceptable alternative is the platelet-albumin criteria in resource-limited settings.

INTRODUCTION AND OBJECTIVES: The Baveno VI criteria to rule out varices needing treatment (VNT) was introduced in 2015. Soon after, the expanded Baveno VI and stepwise platelet-MELD criteria were proposed to be equal/more accurate in ruling out VNT; however, neither has been widely validated. We aimed to validate all 3 criteria in compensated cirrhosis from assorted causes. MATERIALS AND METHODS: We conducted a cross-sectional study including all adult compensated cirrhotic patients who underwent endoscopic surveillance at our center from 2014 to 2018 and had transient elastography (TE), and laboratory data for criteria calculation within 6 months of endoscopies. Exclusion criteria were previous decompensation, unreliable/invalid TE results, and liver cancer. The diagnostic performances of all criteria were evaluated. RESULTS: A total of 128 patients were included. The major cirrhosis etiologies were hepatitis C and B (37.5% and 32.8%, respectively). VNT was observed in 7.8%. All criteria yielded high negative predictive values (NPVs)>95%, missed VNT was observed in 2%, 2.7%, and 2.8% in the original, expanded Baveno VI, and platelet-MELD criteria, respectively. The expanded Baveno VI and the platelet-MELD criteria yielded significantly better specificities and could spare more endoscopies than the original Baveno VI criteria. CONCLUSIONS: All 3 criteria showed satisfactorily high NPVs in ruling out VNT in compensated cirrhosis from various causes. The expanded Baveno VI and the platelet-MELD criteria could spare more endoscopies than the original Baveno VI criteria. From a public health standpoint, the platelet-MELD criteria might be useful in a resource-limited setting where TE is not widely available.

BACKGROUND & AIMS: Alcohol is the leading cause of cirrhosis and liver-related mortality, but we lack serum markers to detect compensated disease. We compared the accuracy of the Enhanced Liver Fibrosis test (ELF), the FibroTest, liver stiffness measurements (made by transient elastography and 2-dimensional shear-wave elastography), and 6 indirect marker tests in detection of advanced liver fibrosis (Kleiner stage ≥F3). METHODS: We performed a prospective study of 10 liver fibrosis markers (patented and not), all performed on the same day. Patients were recruited from primary centers (municipal alcohol rehabilitation, n = 128; 6% with advanced fibrosis) and secondary health care centers (hospital outpatient clinics, n = 161; 36% with advanced fibrosis) in the Region of Southern Denmark from 2013 through 2016. Biopsy-verified fibrosis stage was used as the reference standard. The primary aim was to validate ELF in detection of advanced fibrosis in patients with alcoholic liver disease recruited from primary and secondary health care centers, using the literature-based cutoff value of 10.5. Secondary aims were to assess the diagnostic accuracy of ELF for significant fibrosis and cirrhosis and to determine whether combinations of fibrosis markers increase diagnostic yield. RESULTS: The ELF identified patients with advanced liver fibrosis with an area under the receiver operating characteristic curve (AUROC) of 0.92 (95% confidence interval 0.89-0.96); findings did not differ significantly between patients from primary vs secondary care (P = .917). ELF more accurately identified patients with advanced liver fibrosis than indirect marker tests, but ELF and FibroTest had comparable diagnostic accuracies (AUROC of FibroTest, 0.90) (P = .209 for comparison with ELF). Results from the ELF and FibroTest did not differ significantly from those of liver stiffness measurement in intention-to-diagnose analyses (AUROC for transient elastography, 0.90), but did differ in the per-protocol analysis (AUROC for transient elastography, 0.97) (P = .521 and .004 for comparison with ELF). Adding a serum marker to transient elastography analysis did not increase accuracy. For patients in primary care, ELF values below 10.5 and FibroTest values below 0.58 had negative predictive values for advanced liver fibrosis of 98% and 94%, respectively. CONCLUSION: In a prospective, direct comparison of tests, ELF and FibroTest identified advanced liver fibrosis in alcoholic patients from primary and secondary care with high diagnostic accuracy (AUROC values of 0.90 or higher using biopsy as reference). Advanced fibrosis can be ruled out in primary health care patients based on an ELF value below 10.5 or a FibroTest value below 0.58.

Liver cirrhosis leads to bone loss. To date, information on bone quality (three-dimensional microarchitecture) and, thus, bone strength is scarce. We observed decreased bone quality at both assessed sites, independent of disease severity. Therefore, all patients should undergo early-stage screening for osteoporosis. INTRODUCTION: Recent studies found low bone mineral density in cirrhosis, but data on bone microstructure are scarce. This study assessed weight-bearing and non-weight-bearing bones in patients with cirrhosis and healthy controls. The primary objective was to evaluate trabecular and cortical microarchitecture. METHODS: This was a single-center study in patients with recently diagnosed hepatic cirrhosis. Thirty-two patients and 32 controls participated in this study. After determining the type of cirrhosis, the parameters of bone microarchitecture were assessed by high-resolution peripheral quantitative computed tomography. RESULTS: Both cortical and trabecular microarchitectures showed significant alterations. At the radius, trabecular bone volume fraction was 17% lower (corrected p = 0.028), and, at the tibia, differences were slightly more pronounced. Trabecular bone volume fraction was 19% lower (p = 0.024), cortical bone mineral density 7% (p = 0.007), and cortical thickness 28% (p = 0.001), while cortical porosity was 32% higher (p = 0.023), compared to controls. Areal bone mineral density was lower (lumbar spine - 13%, total hip - 11%, total body - 9%, radius - 17%, and calcaneus - 26%). There was no correlation between disease severity and microarchitecture. Areal bone mineral density (aBMD) measured by dual-energy X-ray absorptiometry (DXA) correlated well with parameters of cortical and trabecular microarchitecture. CONCLUSIONS: Hepatic cirrhosis deteriorates both trabecular and cortical microarchitecture, regardless of disease severity. Areal bone mineral density is diminished at all sites as a sign of generalized affection. In patients with hepatic cirrhosis, regardless of its origin or disease severity, aBMD measurements are an appropriate tool for osteologic screening.

BACKGROUND: The multifactorial mechanisms driving negative health outcomes among risky drinkers with HIV may include immunosenescence. Immunosenescence, aging of the immune system, may be accentuated in HIV and leads to poor outcomes. The liver regulates innate immunity and adaptive immune tolerance. HIV-infected people have high prevalence of liver-related comorbidities. We hypothesize that advanced liver fibrosis/cirrhosis is associated with alterations in T-cell subsets consistent with immunosenescence. METHODS: ART-naïve people with HIV with a recent history of heavy drinking were recruited into a clinical trial of zinc supplementation. Flow cytometry was used to characterize T-cell subsets. The two primary dependent variables were CD8+ and CD4+ T-cells expressing CD28-CD57+ (senescent cell phenotype). Secondary dependent variables were CD8+ and CD4+ T-cells expressing CD45RO + CD45RA- (memory phenotype), CD45RO-CD45RA+ (naïve phenotype), and the naïve phenotype to memory phenotype T-cell ratio (lower ratios associated with immunosenescence). Advanced liver fibrosis/cirrhosis was defined as FIB-4 > 3.25, APRI≥1.5, or Fibroscan measurement ≥10.5 kPa. Analyses were conducted using multiple linear regression adjusted for potential confounders. RESULTS: Mean age was 34 years; 25% female; 88% hepatitis C. Those with advanced liver fibrosis/cirrhosis (N = 25) had higher HIV-1 RNA and more hepatitis C. Advanced liver fibrosis/cirrhosis was not significantly associated with primary or secondary outcomes in adjusted analyses. CONCLUSIONS: Advanced liver fibrosis/cirrhosis was not significantly associated with these senescent T-cell phenotypes in this exploratory study of recent drinkers with HIV. Future studies should assess whether liver fibrosis among those with HIV viral suppression and more advanced, longstanding liver disease is associated with changes in these and other potentially senescent T-cell subsets.

We report an unusual case of severe hepatopulmonary syndrome with previously unrecognized cirrhosis, presenting with acute on chronic dyspnoea, extreme hypoxemia, secondary polycythemia as well as direct identification of arteriovenous communications on computed tomography angiography. Hepatopulmonary syndrome, defined as the combination of hepatopathy, arterial deoxygenation and pulmonary vascular dilatation, is increasingly recognized as a life-threatening complication in advanced liver disease and transplant candidacy. It is usually diagnosed in chronic liver disease patients following pre-transplant evaluation or mild dyspnea investigation. Diagnosis relies on the indirect evidence of pulmonary arteriovenous communications suggested by echocardiography with a bubble study. Clinicians need to be aware of this rare but potential acute presentation at the emergency room.

BACKGROUND: The liver is a central organ for the metabolism of iron and manganese and the places where those metals are commonly deposited overlap in the brain. PURPOSE/HYPOTHESIS: To elucidate the relationship between pallidal T1 hyperintensity and iron deposition in the deep gray matter of liver cirrhosis patients using quantitative susceptibility mapping (QSM). STUDY TYPE: Retrospective case-control study SUBJECTS: In all, 38 consecutive liver cirrhosis patients who received brain magnetic resonance imaging (MRI) as pretransplant evaluation. FIELD STRENGTH/SEQUENCE: QSM was reconstructed from 3D multi- or single-echo phase images at 3T. T1 -weighted images were used for the assessment of pallidal hyperintensity and pallidal index (PI). ASSESSMENT: Patients were divided into two groups according to the presence of pallidal hyperintensity by consensus of two radiologists. Susceptibility values were acquired for five deep gray matter structures. STATISTICAL TEST: QSM measures were compared between two groups using the t-test. We also calculated Pearson correlations between QSM measures and PI. RESULTS: In all, 26 patients showed pallidal hyperintensity (T1 h group) and 12 did not (T1 n group). The susceptibility of the globus pallidus (GP) in the T1 h group (120.6 ± 38.1 ppb) was significantly lower than that in the T1 n group (150.0 ± 35.2, P = 0.030). The susceptibility of the dentate nucleus (DN) in the T1 h group (88.1 ± 31.0) was significantly lower than that in the T1 n group (125.6 ± 30.6, P = 0.001). Negative correlation between the susceptibility of GP (r = -0.37, P = 0.022) and the PI, and between DN (r = -0.43, P < 0.001) and the PI was found. DATA CONCLUSION: Liver cirrhosis patients with pallidal T1 hyperintensity had lower susceptibility values in the GP and DN than those without it. This suggests a possible interaction between iron and manganese in the brains of liver cirrhosis patients. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2018;47:1342-1349.

BACKGROUND & AIMS: The reliability of transient elastography (TE) to assess liver fibrosis is insufficiently validated in alcoholic liver disease (ALD). We aimed to validate the diagnostic utility of TE for liver fibrosis in patients with excessive alcohol consumption and evaluate whether Fibrotest® adds diagnostic value relative to or in combination with TE. METHODS: We conducted a multicentre prospective study on a total of 217 heavy drinkers with high serum aminotransferase levels. Patients underwent liver biopsy, TE, Fibrotest® , PGAA, APRI, FIB-4 and FORNS. The overall diagnostic performance was evaluated by the area under the receiver operating characteristic (AUROC) curves and Obuchowski measures. RESULTS: TE values correlated with fibrosis stage (r=.73; P<.0001) and steatosis stage (r=.19; P<.01). Patients with alcoholic hepatitis had higher TE values than those without alcoholic hepatitis (P<.0001). In an multivariate analysis, fibrosis stage and the presence of alcoholic hepatitis were the only parameters that correlated with liver stiffness. For the diagnosis of advanced fibrosis (F≥3), the AUROC curves were 0.90, 0.85, 0.83, 0.91 and 0.90 for TE, Fibrotest® , PGAA and associations TE-Fibrotest® , TE-PGAA respectively. For the diagnosis of cirrhosis, the AUROC curves were 0.93, 0.88, 0.89, 0.94 and 0.95 respectively. The Obuchowski measures for the diagnosis of fibrosis were 0.94, 0.92, 0.91, 0.95 and 0.94 respectively. The performance of TE was not significantly different than those of Fibrotest® , PGAA and combinations TE-Fibrotest® , TE-PGAA. CONCLUSIONS: TE has excellent diagnostic value for liver fibrosis in alcoholic liver disease. The combined use of TE-Fibrotest® or TE-PGAA does not improve the performance of TE.

BACKGROUND: Endotension can present a real challenge for the long-term success of endovascular aortic repair (EVAR). Sometimes, it can be associated with liver dysfunction and consequent plasmatic alterations as in the 2 cases reported here. METHODS: Significant and progressive abdominal aortic aneurysms (AAA) sac enlargement, without radiologic signs of endoleak, was observed in 2 patients during a 3-year follow-up after EVAR. The first was a 70-year-old man affected by viral liver cirrhosis and the second was a 71-year-old man with cirrhosis due to alcoholic liver disease. RESULTS: Both patients underwent successful conversion to open AAA repair; intraoperative findings confirmed the diagnosis of endotension. CONCLUSIONS: Cirrhosis-induced plasmatic alterations may affect long-term efficacy of EVAR and should be considered when weighing endovascular treatment against open AAA repair in these high-risk patients. Surgical conversion is feasible despite the high procedural risk associated with liver disease.

AIM: To establish the diagnostic accuracy of liver and spleen density (LD and SD) measurements in patients with compensated alcoholic liver cirrhosis (LC) in the diagnosis of portal hypertension. SUBJECTS AND METHODS: The investigation enrolled 83 patients with compensated alcoholic and viral (hepatitis C virus) LC. All the patients underwent LD and SD determinations, abdominal ultrasonography, and endoscopy to detect esophageal varices (EV), as well as examination of blood indices. RESULTS: In viral LC, there were substantial LD differences in patients with and without EV. The patients with EV were ascertained to have higher LD [27.9 (21-45) kPa] than those without EV [19.5 (16-26.2) kPa]. SD was also significantly higher than that in the EV group than in the non-EV group (p<0.001). There were no statistically significant differences in SD and LD or in spleen size in patients with alcoholic LC in relation to the presence of EV. Comparison of patients with EV of different etiology revealed differences in platelet count and spleen size. Thrombocytopenia was more pronounced in HCV-related LC patients (p=0.04). The spleen size in patients with viral LC was higher than that in those with alcoholic LC. CONCLUSION: Elastography of the spleen and liver may be used to identify portal hypertension in patients with viral (HCV) LC (83% sensitivity, 75% specificity) with the following threshold values: LD=26 kPa and SD=50 kPa. The threshold LD and SD values obtained for viral LC do not make possible to diagnose clinically significant portal hypertension (EV) in patients with alcoholic LC. There is a need for further investigations to determine the optimal threshold values of LD and SD for the diagnosis of EV.

AIM: To study the results of dynamic liver ultrasound elastography (LUE) in assessing the risk of complications of liver cirrhosis (LC) of different etiologies and to elaborate a monitoring program for estimation of the predictive value of elastography in patients with LC. SUBJECTS AND METHODS: A total of 194 patients with LC of different etiologies, including 56 patients with alcoholic cirrhosis, 48 with LC and an outcome of nonalcoholic fatty liver disease, 53 with LC and an outcome of chronic hepatitis C, 23 with LC and an outcome of chronic hepatitis B, and 14 with an outcome of coinfection with hepatitis B and D viruses, were examined. An analysis was made between the presence of a number of LC complications and the results of LUE, by constructing the receiver operating characteristic (ROC) curves to select LUE threshold values, in which there was a high risk for LC complications (esophageal varices, bleeding esophageal varices, hepatic encephalopathy, and ascites). RESULTS: The investigation could obtain liver elastography threshold values expressed in kilopascals (kPa), which were proposed for use as a prognostic sign of the presence of complications caused by LC and assessed liver elastography threshold values for its mortality prediction. The predictive value of positive LUE results in determining the risk of different complications was 75.7 to 92.5%; that of negative results was 70 to 92.9%. An algorithm for individualized diagnostic and treatment policy was elaborated in relation to the liver elastography results obtained during the primary examination of a patient. CONCLUSION: The dynamic LUE findings in patients with LC of different etiologies suggest that the proposed LUE threshold values are efficient and may be used in practical healthcare, which will be able to timely correct management tactics for a patient and to monitor his treatment.

Recipient hepatectomy is a challenging liver transplantation (LT) procedure that has life-threatening complications. The current predictive mortality clinic-biological scores (Child/Model for End-Stage Liver Disease [MELD]) do not take into consideration the recipient's liver anatomy. The aim of this study was to evaluate the impact of the dorsal sector anatomy of a cirrhotic liver on the morbidity/mortality rates of hepatectomy. A multicenter retrospective study (clinic-biological and morphologic) was performed from 2013 to 2014. The degree of encirclement of the inferior vena cava (IVC) by the dorsal sector of the liver was measured. The study population included 320 patients. Seventy-four (23%) patients had complete IVC encirclement. A correlation (P = 0.01) has been reported between the existence of a circular dorsal sector and the number of transfusions during LT (4 packed red blood cell [PRBC] transfusions in the group without IVC versus 7 PRBC transfusions in the other group). The existence of such anatomy increases the relative risk of early reoperation for IVC bleeding by 31% (P = 0.05). There is a correlation between alcoholic cirrhosis and dorsal-sector hypertrophy (126 cc versus 147.5 cc; P = 0.05). Concerning surgical time, we found no significant between-group differences. Compared to the severity of cirrhosis, an inverse correlation was observed between the MELD and Child scores and the dorsal sector hypertrophy (P < 0.001). No significant difference in terms of transfusion was found between the temporary portocaval shunt group (n = 168) and the other group (n = 152). The presence of a circular sector is associated with an increased risk of hemorrhage during hepatectomy, as well as an immediate postoperative risk of reoperation.

BACKGROUND: Heavy alcohol consumption causes alcoholic liver disease and is a causal factor of many types of liver injuries and concomitant diseases. It is a true systemic disease that may damage the digestive tract, the nervous system, the heart and vascular system, the bone and skeletal muscle system, and the endocrine and immune system, and can lead to cancer. Liver damage in turn, can present as multiple alcoholic liver diseases, including fatty liver, steatohepatitis, fibrosis, alcoholic cirrhosis, and hepatocellular carcinoma, with presence or absence of hepatitis B or C virus infection. There are three scarring types (fibrosis) that are most commonly found in alcoholic liver disease: centrilobular scarring, pericellular fibrosis, and periportal fibrosis. When liver fibrosis progresses, alcoholic cirrhosis occurs. Hepatocellular carcinoma occurs in 5% to 15% of people with alcoholic cirrhosis, but people in whom hepatocellular carcinoma has developed are often co-infected with hepatitis B or C virus.Abstinence from alcohol may help people with alcoholic disease in improving their prognosis of survival at any stage of their disease; however, the more advanced the stage, the higher the risk of complications, co-morbidities, and mortality, and lesser the effect of abstinence. Being abstinent one month after diagnosis of early cirrhosis will improve the chance of a seven-year life expectancy by 1.6 times. Liver transplantation is the only radical method that may change the prognosis of a person with alcoholic liver disease; however, besides the difficulties of finding a suitable liver transplant organ, there are many other factors that may influence a person's survival.Ultrasound is an inexpensive method that has been used for years in clinical practice to diagnose alcoholic cirrhosis. Ultrasound parameters for assessing cirrhosis in people with alcoholic liver disease encompass among others liver size, bluntness of the liver edge, coarseness of the liver parenchyma, nodularity of the liver surface, size of the lymph nodes around the hepatic artery, irregularity and narrowness of the inferior vena cava, portal vein velocity, and spleen size.Diagnosis of cirrhosis by ultrasound, especially in people who are asymptomatic, may have its advantages for the prognosis, motivation, and treatment of these people to decrease their alcohol consumption or become abstinent.Timely diagnosis of alcoholic cirrhosis in people with alcoholic liver disease is the cornerstone for evaluation of prognosis or choosing treatment strategies. OBJECTIVES: To determine the diagnostic accuracy of ultrasonography for detecting the presence or absence of cirrhosis in people with alcoholic liver disease compared with liver biopsy as reference standard.To determine the diagnostic accuracy of any of the ultrasonography tests, B-mode or echo-colour Doppler ultrasonography, used singly or combined, or plus ultrasonography signs, or a combination of these, for detecting hepatic cirrhosis in people with alcoholic liver disease compared with liver biopsy as a reference standard, irrespective of sequence. SEARCH METHODS: We performed searches in The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Hepato-Biliary Group Diagnostic Test Accuracy Studies Register, The Cochrane Library (Wiley), MEDLINE (OvidSP), EMBASE (OvidSP), and the Science Citation Index Expanded to 8 January 2015. We applied no language limitations.We screened study references of the retrieved studies to identify other potentially relevant studies for inclusion in the review and read abstract and poster publications. SELECTION CRITERIA: Three review authors independently identified studies for possible inclusion in the review. We excluded references not fulfilling the inclusion criteria of the review protocol. We sent e-mails to study authors.The included studies had to evaluate ultrasound in the diagnosis of hepatic cirrhosis using only liver biopsy as the reference standard.The maximum time interval of investigation with liver biopsy and ultrasonography should not have exceeded six months. In addition, ultrasonography could have been performed before or after liver biopsy. DATA COLLECTION AND ANALYSIS: We followed the Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy. MAIN RESULTS: The review included two studies that provided numerical data regarding alcoholic cirrhosis in 205 men and women with alcoholic liver disease. Although there were no applicability concerns in terms of participant selection, index text, and reference standard, we judged the two studies at high risk of bias. Participants in both studies had undergone both liver biopsy and ultrasonography investigations. The studies shared only a few comparable clinical signs and symptoms (index tests).We decided to not perform a meta-analysis due to the high risk of bias and the high degree of heterogeneity of the included studies. AUTHORS' CONCLUSIONS: As the accuracy of ultrasonography in the two included studies was not informative enough, we could not recommend the use of ultrasonography as a diagnostic tool for liver cirrhosis in people with alcoholic liver disease. In order to be able to answer the review questions, we need diagnostic ultrasonography prospective studies of adequate sample size, enrolling only participants with alcoholic liver disease.The design and report of the studies should follow the Standards for Reporting of Diagnostic Accuracy. The sonographic features, with validated cut-offs, which may help identify clinical signs used for diagnosis of fibrosis in alcoholic liver disease, should be carefully selected to achieve maximum diagnostic accuracy on ultrasonography.

OBJECTIVE: To explore the clinical value of virtual touch tissue quantification (VTQ) technique and the PGA index [prothrombin time (P), γ-glutamyl transpeptadase (GG) and apolipoprotein A1 (ApoAl)] in evaluating the degree of liver fibrosis in alcoholic patients.â© METHODS: A total of 64 patients with long-term alcohol history were enrolled for this study. The liver ultrasonography elasticity was examined by VTQ techniques, the VTQ value was assessed in the liver target region, and then the PGA index was calculated. According the liver biopsy biological results, a golden standard, the patients were divided into a non-fibrosis group (n=11), a fibrosis group (n=10), a significant fibrosis group (n=14) and a cirrhosis group (n=29). The diagnostic value of VTQ and PGA index were compared in alcoholic patients following the classification of liver fibrosis.â© RESULTS: The elastography VTQ values were (1.38±0.33), (1.49±0.30), (1.76±0.22) and (2.28±0.53) m/s; while the PGA indexes were 2.09±0.94, 2.30±1.06, 3.57±1.09, and 2.21±1.99 in the non-fibrosis group, the fibrosis group, the significant fibrosis group and the cirrhosis group, respectively. The VTQ value and PGA index were positively correlated with the classification of liver fibrosis (VTG: r=0.719, PGA: r=0.683; both P<0.01).â© CONCLUSION: The alcoholic liver fibrosis can be assessed by noninvasive VTQ technology and PGA index. As a real-time ultrasound elastography technique, VTQ is more accurate than the PGA index. Combination of the two methods is helpful for early diagnosis and treatment in the patients with alcoholic liver fibrosis.

The FibroScan(®) XL probe has been specifically designed for obese patients to measure liver stiffness by transient elastography, but it has not been well tested in non-obese patients. The aim of this study was to compare the M and XL FibroScan(®) probes in a series of unselected obese (body mass index above 30 kg/m(2)) and non-obese patients with chronic liver disease. Two hundred and fifty-four patients underwent a transient elastography examination with both the M and XL probes. The results obtained with the two probes were compared in the whole series and in obese (n=82) and non-obese (n=167) patients separately. The reliability of the examinations was assessed using the criteria defined by Castéra et al. The proportion of reliable exams was significantly higher when the XL probe was used (83% versus 73%; P=.001). This significance was maintained in the group of obese patients (82% versus 55%; P<.001), but not in the non-obese patients (84% versus 83%). Despite a high correlation between the stiffness values obtained with the two probes (R=.897; P<.001), and a high concordance in the estimation of fibrosis obtained with the two probes (Cronbach's alpha value: 0.932), the liver stiffness values obtained with the XL probe were significantly lower than those obtained with the M probe, both in the whole series (9.5 ± 9.1 kPa versus 11.3 ± 12.6 kPa; P<0.001) and in the obese and non-obese groups. In conclusion, transient elastography with the XL probe allows a higher proportion of reliable examinations in obese patients but not in non-obese patients. Stiffness values were lower with the XL probe than with the M probe.

BACKGROUND: Due to the lack of cutoff values validated for specific liver diseases, the purpose of this study was to set up specific magnetic resonance elastography (MRE) cutoff values for asymptomatic liver fibrosis in alcoholic patients. METHODS: Ninety patients underwent 3 clinical exams. The liver stiffness was measured locally with the Fibroscan, and globally through cartographies of shear modulus generated with MRE. The Fibroscan method was chosen as the gold standard to classify the fibrosis. The liver score was also obtained with the Fibrometer A, and the diagnostic performance of the methods was analyzed with receiver-operating characteristic (ROC) curves and cutoff values were calculated. RESULTS: Spearman correlation and area under the ROC curve revealed that MRE is a better diagnostic method than the Fibrometer A, to identify various levels of fibrosis. The results showed that the Fibrometer A was adapted for severe fibrosis. The MRE cutoff values are F1:2.20 kPa, F2:2.57 kPa, F3:3.31 kPa, and F4:4 kPa and were not influenced by the glutamic oxaloacetic transaminase level. By using the ultrasound cutoff values attributed for alcoholism, 66% of patients had a similar liver fibrosis diagnosis as the MRE cutoffs. However, both imaging techniques did not provide the same distribution for minor fibrosis. CONCLUSIONS: None of the imaging techniques (Fibroscan, MRE) could replace the gold standard of the biopsy. However, due to the risk and the unnecessary procedure for the present recruited alcoholic patients, the Fibroscan method was chosen as the reference. Since MRE is currently being used as a clinical exam, the present MRE cutoffs could aid clinicians with their diagnosis of liver fibrosis for alcoholism disease.

OBJECTIVES: The aim of this study was to prove that the incidence of the more unusual and largely under-researched cardiac dysfunction, i.e. diastolic, is more frequent in patients with alcoholic cirrhosis. Comparison of the incidence of left ventricular diastolic dysfunction in medical-ward patients with no prior history of cardiovascular disease to that of the patients with hepatic cirrhosis caused by alcohol abuse was carried out. The study is original from the point of view of examination of patients with cirrhosis of solely alcoholic aetiology in one Central-European university hospital. METHODS: Three methods of echocardiographic examination were used: (i) pulse Doppler echocardiography to assess blood flow through the mitral valve and in the pulmonary veins, (ii) tissue Doppler imaging (TDI) to assess mitral annular motion, and (iii) colour M-mode Doppler echocardiography to assess blood flow from the left atrium into the left ventricle. RESULTS: The results found confirmed that the incidence of left ventricular diastolic dysfunction in patients with alcohol-related liver cirrhosis, classified as Child-Pugh grade A and B, was significantly higher than in the controls without any prior liver disease. Furthermore, our research team has newly noticed how the severity of diastolic dysfunction affects the morbidity and mortality of patients undergoing such treatments as the transjugular intrahepatic portosystemic shunt (TIPS), liver transplantation and other surgical interventions resulting from different indications. CONCLUSION: The high incidence of diastolic dysfunction in cirrhotic alcoholics should not be underestimated. Examination of diastolic dysfunction should be a standard procedure for making clinical decisions about these patients.

In patients with liver cirrhosis and portal hypertension collateral circulation can develop to direct blood from portal to systemic veins allowing decompression of the portal system. A potential complication of portal hypertension is rupture of collateral vessels with subsequent fatal hemorrhage, occurring most commonly in the esophagus. The paraumbilical vein is a recognized collateral pathway in patients with portal hypertension however cases of rupture have been rarely documented. The authors report a case of hemoperitoneum caused by rupture of a paraumbilical vein into a paraumbilical hernia in a man with liver cirrhosis and portal hypertension. Post mortem CT imaging was valuable in localizing the source of hemorrhage in this case.

PURPOSE: We aimed to evaluate and compare the diagnostic performance of Liver Imaging Reporting and Data System (LI-RADS) v2018 for hepatocellular carcinoma (HCC) ≤ 3.0 cm on gadoxetic acid-enhanced MRI according to the etiology of cirrhosis. METHODS: Thirty-eight patients with alcoholic liver cirrhosis (ALC) and 37 with hepatitis C virus-related cirrhosis (HCV) who underwent preoperative MRI and subsequent surgical resection or transplantation were included. For comparison groups, patients with hepatitis B virus-related cirrhosis (HBV) were included by 1:1 matching with HCV and ALC groups according to age, lesion size, and Child-Pugh classification. The imaging characteristics of background liver and focal lesions were analyzed. The diagnostic performance of LI-RADS was compared between HCV and HBV groups, and between ALC and HBV groups. RESULTS: ALC group showed significantly higher frequency of hepatic steatosis (25.8 % vs. 6.1 %, p =.04) and lower frequency of nonperipheral washout on portal venous-phase in HCC (63.2 % vs. 97.1 %, p <.001) compared with HBV group. ALC group showed significantly lower sensitivity than HBV group (52.6 % vs. 88.6 %, p<.001). No significant differences in diagnostic performance were found between HCV and HBV groups. In ALC group, hepatobiliary-phase hypointensity provided significantly higher sensitivity (76.3 % vs. 52.6 %, p =.008). CONCLUSION: The sensitivity of LI-RADS for diagnosing HCC ≤ 3.0 cm was significantly lower in the ALC group than in the HBV group.
