Abstract
Background Early detection of esophageal varices (EV) before the first attack of bleeding is crucial for primary prophylaxis. The current work aims to investigate the use of a combination of FibroScan and platelet count as noninvasive means to identify EV in patients with compensated cirrhosis. Methods Sixty-two patients with compensated hepatitis C virus (HCV)-related cirrhosis were divided into two groups with and without EV. All patients were exposed to complete history, physical examination, laboratory, and endoscopic evaluation. FibroScan was performed for all patients, and the two groups were compared. Results A statistically significant higher mean liver stiffness measurement (LSM) (KPa), lower mean platelet count to splenic diameter ratio (PSR), and higher mean fibrosis-4 (FIB4) score were noticed in those with EV with P < 0.0005. A cutoff value of ≥23.1 for LSM, ≥3.71 for FIB4, and ≥130 mm for splenic diameter have a sensitivity of 94%, 97%, and 97% and a specificity of 81%, 81%, and 68%, respectively, in the detection of varices. Platelet count of ≥112,500 (×103/dl) and of ≥771.33 for PSR have a sensitivity of 84% and 77% and a specificity of 87% and 90%, respectively, to rule out the presence of varices. LSM, FIB4 score, and splenic diameter are predictors of the presence of varices where platelet count and PSR are negative predictors. Conclusion The combination of LSM by transient elastography (TE), PSR, or platelet count can be used to detect a relevant category of patients with compensated cirrhosis who have a very low possibility of EV where endoscopy can be avoided.

Nomogram based on spleen volume expansion rate predicts esophagogastric varices bleeding risk in patients with hepatitis B liver cirrhosis. Front Surg 2022; 9:1019952. [PMID: 36468077 PMCID: PMC9709196 DOI: 10.3389/fsurg.2022.1019952] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 10/31/2022] [Indexed: 08/10/2023] Open
Abstract
BACKGROUND We aimed to explore the risk factors for hemorrhage of esophagogastric varices (EGVs) in patients with hepatitis B cirrhosis and to construct a novel nomogram model based on the spleen volume expansion rate to predict the risk of esophagogastric varices bleeding. METHODS Univariate and multivariate logistic regression analysis was used to analyze the risk factors for EGVs bleeding. Nomograms were established based on the multivariate analysis results. The predictive accuracy of the nomograms was assessed using the area under the curve (AUC or C-index) of the receiver operating characteristic (ROC) and calibration curves. Decision curve analysis was used to determine the clinical benefit of the nomogram. We created a nomogram of the best predictive models. RESULTS A total of 142 patients' hepatitis B cirrhosis with esophagogastric varices were included in this study, of whom 85 (59.9%) had a history of EGVs bleeding and 57 (40.1%) had no EGVs bleeding. The spleen volume expansion rate, serum sodium levels (mmol/L), hemoglobin levels (g/L), and prothrombin time (s) were independent predictors for EGVs bleeding in patients with hepatitis B liver cirrhosis (P < 0.05). The above predictors were included in the nomogram prediction model. The area under the ROC curve (AUROC) of the nomogram was 0.781, the C-index obtained by internal validation was 0.757, and the calibration prediction curve fit well with the ideal curve. The AUROCs of the PLT-MELD and APRI were 0.648 and 0.548, respectively. CONCLUSION In this study, a novel nomogram for predicting the risk of EGVs bleeding in patients with hepatitis B cirrhosis was successfully constructed by combining the spleen volume expansion rate, serum sodium levels, hemoglobin levels, and prothrombin time. The predictive model can provide clinicians with a reference to help them make clinical decisions.

Abstract
BACKGROUND AND AIMS The aim of this study was to identify predictors of non-high-risk gastroesophageal varices and evaluate the probability of the residual high-risk varices in cirrhosis patients after the primary endoscopic treatment. PATIENTS AND METHODS Medical records of the patients with cirrhosis admitted for primary endoscopic prophylaxis gastroesophageal varices hemorrhage were retrospectively analyzed. The patients were divided into high-risk varices and non-high-risk varices groups according to the endoscopy. A nomogram was developed based on the results of multivariate Cox analyses. Accuracy of this model was validated by the concordance index (Harrell's c-index) and calibration curve. RESULTS Altogether 117 patients were enrolled between March 2014 and April 2018. The multivariate Cox analyses identified spleen length <140 mm [odds ratio (OR) = 2.715; P = 0.037), small or medium size of esophageal varices (OR = 4.412; P = 0.017), unaccompanied with gastric varices (OR = 7.025; P = 0.003) and frequency of endoscopic variceal ligation ≥one time per 4 months (OR = 3.834; P = 0.034) as independent factors of non-high-risk varices. All significant predictors were incorporated into a nomogram to predict the residual high-risk varices, which showed a notable accuracy with the concordance index (0.833). CONCLUSION The nomogram-based prediction of residual high-risk varices can be used for risk stratification in cirrhosis patients with gastroesophageal varices.

Longitudinal Analysis of the Effect of Repeated Transarterial Chemoembolization for Liver Cancer on Portal Venous Pressure. Front Oncol 2021; 11:639235. [PMID: 34804911 PMCID: PMC8602787 DOI: 10.3389/fonc.2021.639235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Accepted: 10/22/2021] [Indexed: 12/05/2022] Open
Abstract
Objectives Investigate long-term effects of repeated transarterial chemoembolization (TACE) on portal venous pressure (PVP) using non-invasive surrogate markers of portal hypertension. Methods Retrospective, Institutional Review Board-approved study. 99 patients [hepatocellular carcinoma (HCC) group (n=57); liver metastasis group (n=42)] who underwent 279TACEs and had longitudinal pre-/post-therapy contrast-enhanced-MRI (n=388) and complete blood work were included. Outcomes of interest were platelet count (PC), spleen volume, ascites and portosystemic collaterals. Variables included TACE type/number, tumor type, microcatheter location, Child-Pugh, baseline tumor burden (tumor number/total/largest size), vessel invasion, alpha-fetoprotein, Eastern Cooperative Oncology Group (ECOG) performance status, and Model for End-Stage Liver Disease (MELD) score. Generalized Estimating Equations assessed the associations between TACE and outcomes. Power analysis determined the sample size was sufficient. Results No significant change in PC over time was observed in either groups, regardless of liver function (P>0.05). Baseline spleen volume was 226 cm3 for metastatic group, and was larger by 204 cm3 for HCC group (P<0.001). Spleen volume increased by 20 cm3 (95%CI: 8-32; P=0.001) for both groups after 1stTACE and by 16cm3/TACE (P=0.099) over the full follow-up (up to 9TACEs). Spleen volume also tended to increase by 23cm3 (95%CI: -1–48; P=0.064) with higher tumor burden. Odds of developing moderate/severe ascites for metastatic patients was decreased by 0.5 (95%CI: 0.3–0.9; P=0.014), regardless of the Child-Pugh, and increased by 1.5 (95%CI: 1.2–1.9; P<0.001) among HCC patients with unstable Child-Pugh, whereas no change was noted with stable Child-Pugh. HCC patients with unstable Child-Pugh demonstrated a significant increase in portosystemic collaterals number over time (P=0.008). PVP-related complications such as variceal bleeding post-TACE were low (0.4%). Conclusion Repeated TACEs did seem to have an impact on PVP. However, the increase in PVP had marginal effects with low portal hypertension-related complications.

Novel albumin, bilirubin and platelet criteria for the exclusion of high-risk varices in compensated advanced chronic liver disease: A validation study. Clin Res Hepatol Gastroenterol 2021; 45:101598. [PMID: 33780835 DOI: 10.1016/j.clinre.2020.101598] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Revised: 11/27/2020] [Accepted: 12/01/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND AND AIMS Availability of transient elastography (TE) limits the application of Baveno-VI criteria. In a derivation study, the ABP criteria (Albumin >40 g/l, Bilirubin <22 μmol/l and Platelet >114,000/μl) had been shown to perform well in identifying compensated advanced chronic liver disease (cACLD) patients without high-risk varices (HRV). We aim to externally validate this novel ABP criteria for the exclusion of HRVs among cACLD patients. METHODS Data was retrospectively collected from consecutive cACLD patients with paired TE and esophagogastroduodenoscopy (EGD) performed between 2011 and 2017 in Changi General Hospital, Singapore. We estimate the discriminative ability of ABP criteria in validation cohort using AUROC and calibration-in-the-large. We subsequently compare the performance between ABP and Baveno-VI criteria in the validation cohort. RESULTS Among 314 patients included in our validation cohort, 32 (10.2%) had HRV on screening EGD. Application of ABP criteria within this validation cohort has increased discriminative ability than the derivation cohort. The AUROC of validation and derivation cohort were 0.68 (0.60-0.76) and 0.66 (0.60-0.76), respectively. The mean and standard error for calibration-in-the-large and calibration slope were -0.08 (0.22) and 0.93 (0.26) respectively. The ABP criteria had excellent performance in excluding HRV and will spare more screening EGDs than the Baveno-VI criteria (39.2% vs 27.4%, p < 0.001), without missing more HRVs. CONCLUSION We validated the performance of ABP criteria for the exclusion of HRVs in cACLD patients. ABP criteria is superior to Baveno-VI criteria by sparing more screening EGD without the need of TE.

The von Willebrand Factor antigen to platelet ratio (VITRO) score predicts hepatic decompensation and mortality in cirrhosis. J Gastroenterol 2020; 55:533-542.

Abstract
BACKGROUND The ratio of von Willebrand Factor to platelets (VITRO) reflects the severity of fibrosis and portal hypertension and might thus hold prognostic value. METHODS Patients with compensated cirrhosis were recruited. VITRO, Child-Pugh score (CPS) and MELD were determined at study entry. Hepatic decompensation was defined as variceal bleeding, ascites or hepatic encephalopathy. Liver transplantation and death were recorded. RESULTS One hundred and ninety-four patients with compensated cirrhosis (CPS-A 89%, B 11%; 56% male; median age 56 years; 50% with varices) were included. During a median follow-up of 45 months (IQR 29-61), decompensation occurred in 35 (18%) patients and 14 (7%) patients deceased. The risk of hepatic decompensation was significantly increased in the n = 88 (45%) patients with a VITRO ≥ 2.5 (p < 0.001). Patients with a VITRO ≥ 2.5 had a higher probability of decompensation at 1-year 9% (95% CI 3-16) vs. 0% (95% CI 0-0) and at 2-years 18% (95% CI 10-27%), vs. 4% (95% CI 0-8%) as compared to patients with VITRO < 2.5. Patients with VITRO ≥ 2.5, the estimated 1-year/2-year survival rates were at 98% (95% CI 95-100%) and 94% (95% CI 88-99%) as compared to 100% (95% CI 100-100%) both in the patients with a VITRO < 2.5 (p < 0.001). After adjusting for age, albumin and MELD, VITRO ≥ 2.5 remained as significant predictor of transplant-free mortality (HR 1.38, CI 1.09-1.76; p = 0.007). Patients with compensated cirrhosis and VITRO > 2.1 after hepatitis C eradication remained at significantly increased risk for decompensation (p = 0.033). CONCLUSIONS VITRO is a valuable prognostic tool for estimating the risk of decompensation and mortality in patients with compensated cirrhosis-including the setting after hepatitis C eradication.

Role of Spleen Stiffness Measurement by 2D-Shear Wave Elastography in Ruling Out the Presence of High-Risk Varices in Cirrhotic Patients. Dig Dis Sci 2019; 64:2653-2660. [PMID: 30989464 DOI: 10.1007/s10620-019-05616-4] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 04/05/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIM To evaluate if spleen stiffness measurement (SSM) can rule out the presence of high-risk varices in patients with cirrhosis, avoiding an upper gastrointestinal endoscopy (UGE). METHODS We enrolled 71 cirrhotic patients irrespective of liver disease's etiology. 2D shear wave elastography (SWE) of spleen and UGE was performed. High-risk varices (HRV) were defined as esophageal varices ≥ 5 mm and/or red spots and any gastric varices. RESULTS Esophageal varices were documented in 37 (52.1%) and HRV in 25 (35.2%) patients. SSM was not technically feasible in 7/71 patients (9.8%). From the remaining 64 patients, when those with cholestatic liver disease were excluded (n = 17), SSM < 35.8 kPa was found to exclude well the existence of HRV offering an AUROC of 0.854 (p < 0.001), sensitivity 88.9%, negative predictive value (NPV) 91.3%, specificity 72.4%, and positive predictive value (PPV) 66.7%. Only 2/47 patients (4.3%) were misclassified, and 23 (48.9%) could avoid endoscopy. In the total cohort of 64 patients, SSM < 33.7 kPa was found to exclude well the presence of HRV offering AUROC 0.792 (p < 0.001), sensitivity 91.7%, specificity 60%, NPV 92.3%, and PPV 57.9%. The misclassification rate was 3.1% (2/64), while 26/64 (40.6%) could avoid endoscopy. CONCLUSIONS 2D-SWE of spleen is a reliable method for ruling out the presence of HRV in cirrhotic patients. If larger studies confirm our results, a large number of endoscopies could be avoided.

Non-endoscopic predictors of esophageal varices in children with chronic liver disease and their utility in resource-constrained countries. Indian J Gastroenterol 2019; 38:310-316. [PMID: 31423562 DOI: 10.1007/s12664-019-00960-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Accepted: 04/30/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND Although endoscopy is the standard diagnostic screening test to identify esophageal varices in patients with chronic liver disease (CLD), selective endoscopy in patients who are at higher risk of having varices may be cost-effective in a resource-constrained country. The aim of this prospective study was to identify non-endoscopic parameters that may predict the presence of varices, especially high-risk esophageal varices in children with CLD. METHODS From January 2016 through March 2018, consecutive children with CLD without a history of variceal bleeding were prospectively included. Esophagogastroduodenoscopy was done in all the children to detect and to grade esophageal varices. Both univariate and multivariate logistic regression analyses were done using SPSS version 22 to identify factors associated with esophageal varices. RESULTS The mean age of 84 children was 9.7 ± 3.2 years (male 44). Esophageal varices were present in 71.4% of children and 55% of them had large varices. On univariate analysis, low platelet count (< 100,000/mm3) and splenomegaly were found to be associated with the presence of esophageal varices (p = 0.006 and 0.001, respectively) and large varices (p = 0.03 and 0.01, respectively). On multivariate analysis, both low platelet count and splenomegaly were independent predictors for the presence of esophageal varices (respectively, OR 11.21, 95% CI 1.2-96.9; and OR 11.39, 95% CI 3.19-40.59). CONCLUSIONS Splenomegaly and low platelet count independently predict the presence of any grade of esophageal varices and can be used as screening tests to select children for endoscopy. This strategy may help in relieving medical, social, and economic costs in resource-constrained countries.

Abstract
BACKGROUND Liver stiffness measurement (LSM) <20 kPa and platelet count >150,000/mm3 exclude varices needing treatment (VNT) in viral compensated advanced chronic liver disease (cACLD), saving-up to 20-25% endoscopies (Baveno VI criteria). Refinements of such criteria to further reduce endoscopies and an approach without LSM (Platelet 150/MELD 6) were later proposed. AIMS To assess LSM 25/platelet 125, LSM 25/platelet 110 (Expanded-Baveno VI) and Platelet 150/MELD 6 accuracy versus Baveno VI criteria, and the impact of platelet count variability on criteria accuracy in all-etiologies cACLD. METHODS cACLD patients undergoing screening endoscopy with laboratory data within 6 months and LSM within one year. RESULTS Of 442 patients, 31% had varices (7% with VNT). Baveno VI criteria had 100% sensitivity (Se) and negative predictive value (NPV) and spared 19.5% endoscopies. "LSM 25/platelet 125" and "Expanded-Baveno VI" criteria maintained such accuracy, sparing 15% and 24% more endoscopies, respectively (p < 0.001). Platelet 150/MELD 6 was less accurate, misclassifying 10% VNT. Platelet count variability exceeded 8% and one VNT patient was misclassified with both "Expanded-Baveno VI" and "LSM 25/platelet 125" criteria considering the previous platelet count. CONCLUSIONS Both "Expanded-Baveno VI" and "LSM 25/platelet 125" criteria are accurate in cACLD, but the former are more advantageous. Platelet 150/MELD 6 proved inadequate.

Abstract
BACKGROUND/AIMS The aim of the present study was to evaluate the histopathological findings of cirrhosis together with clinical and laboratory parameters, and to investigate their relationship with esophageal varices that are portal hypertension findings. MATERIALS AND METHODS A total of 67 (42 male and 25 female) patients who were diagnosed with cirrhosis were included in the study. The mean age of the patients was 51.6±19.0 (1-81) years. The biopsy specimens of the patients were graded in terms of fibrosis, nodularity, loss of portal area, central venous loss, inflammation, and steatosis. The spleen sizes were graded ultrasonographically, and the esophageal varices were graded endoscopically. RESULTS In the multivariate regression analysis, there was a correlation between the advanced disease stage (Child-Pugh score odds ratio (OR): 1.47, 95% confidence interval (CI): 1.018-2.121, p=0.040), presence of micronodularity (OR: 0.318, 95% CI: 0.120-0.842, p=0.021), grade of central venous loss (OR: 5.231, 95% CI: 1.132-24.176, p=0.034), and presence of esophageal varicose veins. CONCLUSION Although thrombocytopenia and splenomegaly may predict the presence of large esophageal varices, cirrhosis histopathology is the main factor in the presence of varices.

Abstract
Vibration controlled transient elastography (VCTE) is validated for the evaluation of hepatic fibrosis in different liver diseases. Sickle cell liver disease (SCLD) results from a cumulative hepatic injury and its lifelong and progressive nature raises the need for a non-invasive tool for fibrosis evaluation. Fifty patients, aged between 23 and 59 years with sickle cell disease and suspected SCLD underwent a VCTE followed by a liver biopsy. Biopsies were evaluated for various scores of liver disease that were then correlated to VCTE score. 90% of our patients had an Ishak Fibrosis (IF) score between 0-2 (Group A-minimal to no fibrosis) and 10% of the patients had IF score between 3-6 (Group B-advanced fibrosis). The median Transient Elastography (TE) for patients in Groups A and B was 4·8 kilopascals (kPa) and 17·6 kPa, respectively. A positive correlation was shown between TE and IF score, R = 0·0·68 (P = <0·0001); a positive correlation was also shown with Histology Activity Index fibrosis score, R = 0·64 (P = <0·0001). This study emphasises the need for further studies of non-invasive tools and their utility in liver fibrosis evaluation of patients with SCLD.

Sofosbuvir Based Regimens in the Treatment of Chronic Hepatitis C with Compensated Liver Cirrhosis in Community Care Setting. Int J Hepatol 2018; 2018:4136253. [PMID: 30155312 PMCID: PMC6093047 DOI: 10.1155/2018/4136253] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 07/19/2018] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Direct-acting antiviral (DAA) drugs have been highly effective in the treatment of chronic hepatitis C (CHC) infection. We aim to evaluate the treatment response of Sofosbuvir based DAA in CHC patients with compensated liver cirrhosis as limited data exists in the real-world community setting. METHODS All the CHC patients with compensated liver cirrhosis treated with Sofosbuvir based DAAs between January 2014 and December 2017 in a community clinic setting were retrospectively analyzed. Pretreatment baseline patient characteristics, treatment efficacy with the sustained virologic response at 12 weeks posttreatment (SVR12), and adverse reactions were assessed. RESULTS One hundred and twelve patients with CHC infection and concurrent compensated cirrhosis were included in the study. Black patients represented the majority of the study population (64%). Eighty-seven patients were treated with Ledipasvir/Sofosbuvir (LDV/SOF) ±Ribavirin and 25 patients were treated with Sofosbuvir/Velpatasvir (SOF/VEL). Overall, SVR 12 after treatment was achieved in 90% in patients who received one of the two DAA regimens (89.7% in LDV/SOF group and 92% in SOF/VEL group). SVR 12 did not vary based on age, sex, body mass index, baseline HCV viral load, HCV/HIV coinfection, type of genotype, and prior treatment status. Apart from a low platelet count, there were no other factors associated with a statistical difference in SVR 12(p=0.002) between the two regimens. Fatigue (35%) was the most common adverse effect and no patients discontinued treatment due to adverse effects. CONCLUSION In the community care setting, Sofosbuvir based DAAs are safe, effective with high overall SVR, and well tolerated in patients with CHC patients with compensated liver cirrhosis.

Abstract
Here, we review recent improvements made to different noninvasive tests used for the diagnosis of esophageal varices (EV) in the light of the recent Baveno VI recommendation and with an emphasis on clinical application. Like for fibrosis tests, these noninvasive EV tests can be classified as direct markers when they provide a visualization of EV (including all imaging procedures like endoscopy or radiology) and as indirect markers when they do not (blood markers or elastometry). Clinical descriptors expressed as percentages, especially the spared endoscopy rate and the missed high-risk esophageal varices (HREV) rate, are more eloquent in this setting than classical statistical descriptors like accuracy. Single biomarkers are insufficient, generally due to a missed HREV rate exceeding the acceptable limit of 5% indicated in the Baveno VI consensus. Thus, biomarker combinations are currently garnering the most interest. The Baveno VI recommendation states that in alcoholic and viral cirrhoses, screening endoscopy can be safely set aside for patients with liver stiffness<20kPa and platelets>150G/L. The Baveno rule's mean missed HREV rate is<5% but its spared endoscopy rate is<20%. New combinations or stepwise algorithms show promise but must be validated. Going forward, the Baveno rule provides a simple noninvasive method to rule out HREV in clinical practice but the need for further research continues. The noninvasive diagnosis of HREV will be significantly improved by new, simple and affordable combinations.

Abstract
BACKGROUND & AIMS Large oesophageal varice (LEV) screening is recommended in cirrhosis. We performed a prospective study to improve non-invasive LEV screening. DESIGN 287 patients with cirrhosis had upper gastrointestinal endoscopy (LEV reference), oesophageal capsule endoscopy (ECE), liver elastography and blood marker analyses. CirrhoMeter (cirrhosis blood test), the most accurate non-invasive LEV test, was segmented for cirrhosis (reference comparator) or LEV. VariScreen, a sequential and partially minimally invasive diagnostic algorithm, was developed by multivariate analysis. It uses CirrhoMeter first, then ECE if CirrhoMeter cannot rule LEV out or in, and finally endoscopy if CirrhoMeter+ECE combination remains uninformative. RESULTS Diagnostic effectiveness rates for LEV were: cirrhosis-segmented CirrhoMeter: 14.6%, LEV-segmented CirrhoMeter: 34.6%, ECE: 60.6% and VariScreen: 66.4% (P ≤ .001 for overall or pair comparison). The respective missed LEV rates were: 2.8%, 5.6%, 8.3% and 5.6% (P = .789). Spared endoscopy rates were, respectively: 15.6%, 36.0%, 70.6% and 69%, (P < .001 for overall or paired comparison except ECE vs VariScreen: P = .743). VariScreen spared 38% of ECE and reduced missed LEV by 87% compared to classical ECE performed in all patients. Excepting cirrhosis-segmented CirrhoMeter, these spared endoscopy rates were significantly higher than that of the Baveno VI recommendation (using platelets and Fibroscan): 18.4% (P < .001). Ascites and Child-Pugh class independently predicted endoscopy sparing by VariScreen: from 86.0% in compensated Child Pugh class A to 24.1% in Child-Pugh class C with ascites. CONCLUSION VariScreen algorithm significantly reduced the missed LEV rate with ECE by 87%, ECE use by 38% and endoscopy requirement by 69%, and even 86% in compensated cirrhosis.

Abstract
BACKGROUND AND AIM The aim was to validate noninvasive methods to predict the presence of gastroesophageal varices (GEV) in patients with suspected compensated advanced chronic liver disease. METHODS We retrospectively reviewed clinical and radiological data collected prospectively between September 2013 and September 2015. We reviewed 442 consecutive patients with suspected compensated advanced chronic liver disease measured by transient elastography (TE) and a gastroscopy. We evaluated platelets, spleen diameter, TE, liver stiffness × spleen size/platelets (LSPS), variceal risk index (VRI), Baveno VI strategy, and Augustin algorithm. RESULTS One hundred sixty-one out of 442 patients were included. Patients with GEV were compared with patients without GEV and showed statistically significant differences in platelet count (117 SD 51 vs 149 SD 62; P = 0.02), spleen diameter (13.0 SD 1.9 vs 11.5 SD 2; P = 0.003), and TE (28 SD 15 vs 19 SD 10; P = 0.001). Single methods (platelet count and TE) diagnosed correctly 51% and 71.4% of patients. Combined methods (LSPS, VRI, Baveno VI, and Augustin algorithm) diagnosed correctly 78%, 83.6%, 45.3%, and 57.1% of patients. Patients with GEV misdiagnosed: platelets 5/161 (3.1%), TE 6/161 (3.7%), LSPS 16/159 (10%), VRI 18/159 (11.3%), Baveno VI 3/161 (1.8%), and Augustin algorithm 6/161 (3.7%). Rate of unnecessary gastroscopies: platelets 46%, TE 25%, LSPS 13%, VRI 6%, Baveno VI 53%, and Augustin algorithm 39.1%. CONCLUSIONS A significant number of patients were classified correctly using TE, LSPS, and VRI; however, LSPS and VRI had unacceptable rates of misdiagnoses. TE is the best noninvasive single method and the Baveno VI strategy the best combined method.

Abstract
OBJECTIVE To explore the noninvasive indicators for predicting the occurrence of esophageal varices (EV) in patients with liver cirrhosis. METHODS A total of 202 patients with liver cirrhosis caused by hepatitis B or C or alcoholic hepatic disease were enrolled in this study. EV and high risk esophageal varices (HREV) were confirmed in these patients by gastroscopy. The hematological, serum biochemical and ultrasonic parameters of the patients were analyzed, and a model for predicting EV was established by stepwise logistic regression analysis. RESULTS The areas under receiver operating characteristics curve (AUROC) of splenic thickness (SPT) for detecting EV and HREV were 0.827 and 0.766, respectively. The combined index USWA (SPT, US, WBC and albumin [ALB]) showed an AUROC of 0.873 for detecting EV, and the index SPA (combining SPT and ALB) showed an AUROC of 0.777 for detecting HREV. The direct combination of SPT with USWA or with platelet/splenic thickness ratio (PSA) was capable of completely excluding a definite diagnosis of EV, while the sequential combination of SPT with USWA or with platelet was capable of a diagnosis of EV and clarifying the condition of EV in approximately half of the cirrhotic patients in the absence of gastroscopic findings. The combination of SPT and SPA allowed for a definite diagnosis of the condition of HREV in 10% of the cirrhotic patients. CONCLUSION SPT combined with SPT derived indexes or platelet status allows for a definite diagnosis of EV in patients with liver cirrhosis to offer a noninvasive option for diagnosis.

Abstract
BACKGROUND Current guidelines recommend screening of people with oesophageal varices via oesophago-gastro-duodenoscopy at the time of diagnosis of hepatic cirrhosis. This requires that people repeatedly undergo unpleasant invasive procedures with their attendant risks, although half of these people have no identifiable oesophageal varices 10 years after the initial diagnosis of cirrhosis. Platelet count, spleen length, and platelet count-to-spleen length ratio are non-invasive tests proposed as triage tests for the diagnosis of oesophageal varices. OBJECTIVES Primary objectives To determine the diagnostic accuracy of platelet count, spleen length, and platelet count-to-spleen length ratio for the diagnosis of oesophageal varices of any size in paediatric or adult patients with chronic liver disease or portal vein thrombosis, irrespective of aetiology. To investigate the accuracy of these non-invasive tests as triage or replacement of oesophago-gastro-duodenoscopy. Secondary objectives To compare the diagnostic accuracy of these same tests for the diagnosis of high-risk oesophageal varices in paediatric or adult patients with chronic liver disease or portal vein thrombosis, irrespective of aetiology.We aimed to perform pair-wise comparisons between the three index tests, while considering predefined cut-off values.We investigated sources of heterogeneity. SEARCH METHODS The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Hepato-Biliary Group Diagnostic Test Accuracy Studies Register, the Cochrane Library, MEDLINE (OvidSP), Embase (OvidSP), and Science Citation Index - Expanded (Web of Science) (14 June 2016). We applied no language or document-type restrictions. SELECTION CRITERIA Studies evaluating the diagnostic accuracy of platelet count, spleen length, and platelet count-to-spleen length ratio for the diagnosis of oesophageal varices via oesophago-gastro-duodenoscopy as the reference standard in children or adults of any age with chronic liver disease or portal vein thrombosis, who did not have variceal bleeding. DATA COLLECTION AND ANALYSIS Standard Cochrane methods as outlined in the Cochrane Handbook for Diagnostic Test of Accuracy Reviews. MAIN RESULTS We included 71 studies, 67 of which enrolled only adults and four only children. All included studies were cross-sectional and were undertaken at a tertiary care centre. Eight studies reported study results in abstracts or letters. We considered all but one of the included studies to be at high risk of bias. We had major concerns about defining the cut-off value for the three index tests; most included studies derived the best cut-off values a posteriori, thus overestimating accuracy; 16 studies were designed to validate the 909 (n/mm3)/mm cut-off value for platelet count-to-spleen length ratio. Enrolment of participants was not consecutive in six studies and was unclear in 31 studies. Thirty-four studies assessed enrolment consecutively. Eleven studies excluded some included participants from the analyses, and in only one study, the time interval between index tests and the reference standard was longer than three months. Diagnosis of varices of any size. Platelet count showed sensitivity of 0.71 (95% confidence interval (CI) 0.63 to 0.77) and specificity of 0.80 (95% CI 0.69 to 0.88) (cut-off value of around 150,000/mm3 from 140,000 to 150,000/mm3; 10 studies, 2054 participants). When examining potential sources of heterogeneity, we found that of all predefined factors, only aetiology had a role: studies including participants with chronic hepatitis C reported different results when compared with studies including participants with mixed aetiologies (P = 0.036). Spleen length showed sensitivity of 0.85 (95% CI 0.75 to 0.91) and specificity of 0.54 (95% CI 0.46 to 0.62) (cut-off values of around 110 mm, from 110 to 112.5 mm; 13 studies, 1489 participants). Summary estimates for detection of varices of any size showed sensitivity of 0.93 (95% CI 0.83 to 0.97) and specificity of 0.84 (95% CI 0.75 to 0.91) in 17 studies, and 2637 participants had a cut-off value for platelet count-to-spleen length ratio of 909 (n/mm3)/mm. We found no effect of predefined sources of heterogeneity. An overall indirect comparison of the HSROCs of the three index tests showed that platelet count-to-spleen length ratio was the most accurate index test when compared with platelet count (P < 0.001) and spleen length (P < 0.001). Diagnosis of varices at high risk of bleeding. Platelet count showed sensitivity of 0.80 (95% CI 0.73 to 0.85) and specificity of 0.68 (95% CI 0.57 to 0.77) (cut-off value of around 150,000/mm3 from 140,000 to 160,000/mm3; seven studies, 1671 participants). For spleen length, we obtained only a summary ROC curve as we found no common cut-off between studies (six studies, 883 participants). Platelet count-to-spleen length ratio showed sensitivity of 0.85 (95% CI 0.72 to 0.93) and specificity of 0.66 (95% CI 0.52 to 0.77) (cut-off value of around 909 (n/mm3)/mm; from 897 to 921 (n/mm3)/mm; seven studies, 642 participants). An overall indirect comparison of the HSROCs of the three index tests showed that platelet count-to-spleen length ratio was the most accurate index test when compared with platelet count (P = 0.003) and spleen length (P < 0.001). DIagnosis of varices of any size in children. We found four studies including 277 children with different liver diseases and or portal vein thrombosis. Platelet count showed sensitivity of 0.71 (95% CI 0.60 to 0.80) and specificity of 0.83 (95% CI 0.70 to 0.91) (cut-off value of around 115,000/mm3; four studies, 277 participants). Platelet count-to-spleen length z-score ratio showed sensitivity of 0.74 (95% CI 0.65 to 0.81) and specificity of 0.64 (95% CI 0.36 to 0.84) (cut-off value of 25; two studies, 197 participants). AUTHORS' CONCLUSIONS Platelet count-to-spleen length ratio could be used to stratify the risk of oesophageal varices. This test can be used as a triage test before endoscopy, thus ruling out adults without varices. In the case of a ratio > 909 (n/mm3)/mm, the presence of oesophageal varices of any size can be excluded and only 7% of adults with varices of any size would be missed, allowing investigators to spare the number of oesophago-gastro-duodenoscopy examinations. This test is not accurate enough for identification of oesophageal varices at high risk of bleeding that require primary prophylaxis. Future studies should assess the diagnostic accuracy of this test in specific subgroups of patients, as well as its ability to predict variceal bleeding. New non-invasive tests should be examined.

Abstract
Portal hypertension is the central driver of complications in patients with chronic liver diseases and cirrhosis. The diagnosis of portal hypertension has important prognostic and clinical implications. In particular, screening for varices in patients with portal hypertension can effectively reduce the morbidity and mortality of variceal bleeding. In this article, we review the invasive and non-invasive methods to assess portal hypertension. Hepatic venous pressure gradient remains the gold standard to measure portal pressure but is invasive and seldom performed outside expert centers and research settings. In recent years, a number of non-invasive tests of fibrosis have shown good correlation with liver histology. They also show promise in identifying patients with portal hypertension and large varices. As a result, the latest Baveno VI consensus guidelines endorse the use of liver stiffness measurement by transient elastography and platelet count as initial assessment to select patients for varices screening. On the other hand, the performance of non-invasive tests in assessing the response to non-selective beta-blockers or transjugular intrahepatic portosystemic shunting is either suboptimal or unclear.

Abstract
BACKGROUND/AIMS Cirrhosis and portal hypertension are characterised by a hyperdynamic circulation, which is independently associated with variceal size. Non-invasive techniques for measurement of systemic haemodynamics are now available. The aim of the study was to prospectively assess the accuracy of systemic haemodynamics measured non-invasively for the detection of oesophageal varices in cirrhotic patients as compared to other currently available non-invasive methods. METHODS In a study of 29 cirrhotic patients, systemic haemodynamics were studied non-invasively using the Finometer® (mean arterial pressure (MAP), cardiac output (CO)/index, heart rate (HR), peripheral vascular resistance) and portal pressure was assessed by hepatic venous pressure gradient. Sensitivity, specificity, predictive values and area under the receiver operating characteristic (ROC) curves were assessed for predicting presence of varices and large oesophageal varices. Results were compared to child's classification, platelet/spleen ratio and ALT/AST ratios as predictors of the presence of large varices. RESULTS Using finometry large oesophageal varices were correctly predicted in 83% of patients compared to other non-invasive techniques (range 66-76%). CONCLUSIONS Non-invasive assessment of systemic haemodynamics using finometry could aid the identification of patients who do not immediately require variceal surveillance reducing the numbers of endoscopies and ensuring services are provided to those most likely to benefit.

Abstract
BACKGROUND AND AIMS Patients with chronic hepatitis C virus (HCV) infection may develop cirrhosis with portal hypertension, reflected by decreased platelet count and splenomegaly. This retrospective cohort study aimed to assess changes in platelet counts after antiviral therapy among chronic HCV-infected patients with advanced fibrosis. METHODS Platelet counts and spleen sizes were recorded in an international cohort of patients with Ishak 4-6 fibrosis who started antiviral therapy between 1990 and 2003. Last measured platelet counts and spleen sizes were compared with their pre-treatment values (within 6 months prior to the start of therapy). All registered platelet count measurements from 24-week following cessation of antiviral therapy were included in repeated measurement analyses. RESULTS This study included 464 patients; 353 (76%) had cirrhosis and 187 (40%) attained sustained virological response (SVR). Among patients with SVR, median platelet count, increased by 35 × 10(9) /L (IQR 7-62, P < 0.001). In comparison, patients without SVR showed a median decline of 17 × 10(9) /L (IQR -5-47, P < 0.001). In a subgroup of 209 patients, median decrease in spleen size was 1.0 cm (IQR 0.3-2.0) for patients with SVR, while median spleen size increased with 0.6 cm (IQR -0.1-2.0, P < 0.001) among those without SVR. The changes in spleen size and platelet count were significantly correlated (R = -0.41, P < 0.001). CONCLUSIONS Among chronic HCV-infected patients with advanced hepatic fibrosis, the platelet counts improved following SVR and the change in platelets correlated with the change in spleen size following antiviral therapy. These results suggest that HCV eradication leads to reduced portal pressure.

Abstract
BACKGROUND Abdominal ultrasound (US) may provide data on the presence of esophageal varices in cirrhosis. We assess the diagnostic accuracy of this procedure. PATIENTS AND METHODS Retrospective recording of clinical data was carried out in cirrhotic patients who underwent abdominal US and upper gastrointestinal endoscopy. We compared patients with and without large varices and assessed the value of US in predicting the presence of these lesions as well as other significant variables. RESULTS Of the 353 patients included, 123 (35%) had esophageal varices. The presence of US signs of portal hypertension independently predicted the existence of esophageal varices with a sensitivity of 87.9%, a specificity of 34.9%, a positive predictive value of 40.6%, and a negative predictive value of 85.1%, which could increase to 91.5% if the patient presented plasma albumin and platelet concentrations above the mean values (3.1 g/dl and 122×10 cells/l, respectively). Plasma albumin and platelet concentrations were the two other variables with independent predictive capacity. Applying these selection criteria, up to 30% of screening endoscopies may not be necessary, and up to 43% in patients with compensated cirrhosis. In patients with decompensated cirrhosis, however, US does not have predictive capacity. The results obtained are comparable with those reported for transient elastography. CONCLUSION Abdominal US is a highly reliable technique for detecting patients with a low risk of presenting esophageal varices. Its use may avoid up to 43% of screening endoscopies in patients with compensated cirrhosis. The results obtained are similar to those observed using transient elastography.

Abstract
Liver cirrhosis in Mexico is one of the most important causes of death in persons between the ages of 25 and 50 years. One of the reasons for therapeutic failure is the lack of knowledge about the molecular mechanisms that cause liver disorder and make it irreversible. One of its prevalent anatomical characteristics is an excessive deposition of fibrous tissue that takes different forms depending on etiology and disease stage. Liver biopsy, traditionally regarded as the gold standard of fibrosis staging, has been brought into question over the past decade, resulting in the proposal for developing non-invasive technologies based on different, but complementary, approaches: a biological one that takes the serum levels of products arising from the fibrosis into account, and a more physical one that evaluates scarring of the liver by methods such as ultrasound and magnetic resonance elastography; some of the methods were originally studied and validated in patients with hepatitis C. There is great interest in determining non-invasive markers for the diagnosis of liver fibrosis, since at present there is no panel or parameter efficient and reliable enough for diagnostic use. In this paper, we describe the biomarkers that are currently being used for studying liver fibrosis in humans, their advantages and disadvantages, as well as the implementation of new-generation technologies and the evaluation of their possible use in the diagnosis of fibrosis.

Abstract
BACKGROUND Oesophago-gastroduodenoscopy is the standard method for the diagnosis of recurrent oesophago-gastric varices after endoscopic treatment and eradication. The aim of this study was to evaluate the PillCam Eso capsule endoscopy in this setting. METHODS Prospective, multicentre study in which patients with history of oesophageal varices treated by band ligation underwent PillCam Eso capsule and oesophago-gastroduodenoscopy. Capsule recordings were blindly read by two endoscopists. Indication for a new prophylactic treatment and patient satisfaction were determined for both procedures. RESULTS 80 patients (80% males, mean age: 57±12 years) were included, after a median delay of 16 months from last endoscopic treatment. Recurrent oesophageal varices requiring a new prophylactic treatment were detected in 26 patients (32.5%). The mean oesophageal transit time of the capsule was 153 s (range 2-930 s). Capsule sensitivity, specificity, negative and positive predictive values for indication of new prophylactic treatments were 65%, 83%, 83%, and 65%, respectively. Capsule adequately classified 77.5% of the patients for prophylaxis indication. Inter-observer concordance for capsule readings was 88% for the prophylaxis indication. CONCLUSION This study demonstrates that accuracy of PillCam Eso capsule for the diagnosis of recurrent oesophageal varices after endoscopic eradication is suboptimal. PillCam Eso capsule might therefore be proposed in patients unable or unwilling to undergo oesophago-gastroduodenoscopy.

Abstract
OBJECTIVE Esophageal varices are a consequence of portal hypertension in cirrhotic patients. Current guidelines recommend that all cirrhotic patients undergo screening endoscopy at diagnosis to identify patients with varices at high risk of bleeding who will benefit from primary prophylaxis. This practice increases costs, involves a degree of invasiveness and discomfort and places a heavy burden on endoscopy units. Several studies have evaluated possible noninvasive predictors of esophageal varices, but most of these studies remain controversial. METHODS The intra-abdominal portion of the esophagus in 673 patients who presented with liver cirrhosis and portal hypertension was examined using standard 2-dimensional (2D) ultrasound. A direct relationship between the degree of varices observed on upper endoscopy and the intra-abdominal esophageal wall thickness was detected using 2D ultrasound. RESULTS The mean thicknesses of the esophageal wall were 3.7 ± 0.5 mm (mean ± standard deviation) in normal individuals, 7.3 ± 3.3 mm in those with esophageal varices and 8.65 ± 1.98 mm in those with risky esophageal varices. The overall accuracy of 2D ultrasound was 95%. CONCLUSIONS The intra-abdominal esophagus should be observed during abdominal ultrasound examination in patients with liver cirrhosis. Two-dimensional ultrasound can play an important role in screening for esophageal varices.

Abstract
OBJECTIVE To assess the value of the liver and spleen viscoelastic parameters at multifrequency MR elastography to determine the degree of portal hypertension and presence of high-risk oesophageal varices in patients with cirrhosis. METHODS From January to September 2012, 36 consecutive patients with cirrhosis evaluated for transplantation were prospectively included. All patients underwent hepatic venous pressure gradient (HVPG) measurements and endoscopy to assess oesophageal varices. Multifrequency MR elastography was performed within the liver and spleen. The shear, storage and loss moduli were calculated and compared to the HVPG with Spearman coefficients and multiple regressions. Patients with and without severe portal hypertension and high-risk varices were compared with Mann-Whitney tests, logistic regression and ROC analysis. RESULTS The liver storage and loss moduli and the spleen shear, storage and loss moduli correlated with the HVPG. At multiple regression, only the liver and the spleen loss modulus correlated with the HVPG (r = 0.44, p = 0.017, and r = 0.57, p = 0.002, respectively). The spleen loss modulus was the best parameter for identifying patients with severe portal hypertension (p = 0.019, AUROC = 0.81) or high-risk varices (p = 0.042, AUROC = 0.93). CONCLUSIONS The spleen loss modulus appears to be the best parameter for identifying patients with severe portal hypertension or high-risk varices. KEY POINTS 1. Noninvasive HVPG assessment can be performed with liver and spleen MR elastography 2. The spleen loss modulus enables the detection of high-risk oesophageal varices 3. The spleen loss modulus enables the detection of severe portal hypertension.

Abstract
OBJECTIVE The aim of this study was to identify ultrasonographic predictors of esophageal varices (EVs) in children and adolescents with chronic liver disease (CLD) and extrahepatic portal venous obstruction (EHPVO). METHODS This study evaluates 53 patients younger than 20 years with CLD or EHPVO and no history of bleeding or prophylactic EVs treatment. They were divided into 2 groups: group I (35 with CLD) and group II (18 with EHPVO). Splenorenal shunt (SS), gallbladder wall varices, gallbladder wall thickening (GT), and lesser omental thickness (LOT) were compared with the presence of EVs, gastric varices, and portal hypertensive gastropathy (PHG). Univariate (χ² test, Fisher exact test, and Wilcoxon signed rank test) and multivariate (logistic regression) analyses were performed. The area under the receiver operating curve was calculated. RESULTS EVs were observed in 48.5% of patients with CLD and in 83.3% of patients with EHPVO. SS (P = 0.0329) and LOT (P = 0.0151) predicted EV among patients with CLD. A median of 5.3 mm of LOT was considered a predictor of EVs among these patients. Multivariate analysis showed SS as an independent predictor of EVs in patients with EHPVO (odds ratio 15). Gallbladder varices (P = 0.0245) and GT (P = 0.0289) predicted EVs among patients with EHPVO. PHG occurred more often among patients with CLD who had SS (P = 0.0384) and greater LOT (P = 0.0226). CONCLUSIONS SS and a greater LOT were indicative of EV among children and adolescents with CLD. Gallbladder varices and GT were indicative of EVs among patients with EHPVO. SS and a greater LOT were indicative of PHG among patients with CLD.

Abstract
BACKGROUND Decreased platelet count has been observed in various liver diseases, but its significance in primary biliary cirrhosis (PBC) remains unknown. The present study aimed to evaluate the predictive value of the platelet count at diagnosis for PBC-related complications in patients newly diagnosed with PBC and treated with ursodeoxycholic acid (UDCA). METHODS Ninety-six PBC patients without complications treated with UDCA immediately after diagnosis were retrospectively reviewed. All hematologic and chemical parameters, Mayo risk score and PBC-related complications including upper gastrointestinal hemorrhage, presence of ascites, serum bilirubin concentration > 102.6 μmol/L and onset of hepatic encephalopathy were extracted. The associations between these parameters at diagnosis and complications were determined and the prognostic value of the platelet count was evaluated by receiver operating characteristics (ROC) analysis, Kaplan-Meier method and Cox proportional hazard model with the hazard ratio (HR) and 95% confidence interval (CI) calculated. RESULTS Patients with PBC-related complications had significantly decreased platelet count and serum bilirubin concentration, prolonged prothrombin time, and increased Mayo risk score compared to those without complications. A platelet count of ≤ 132.5 × 10(9)/L was associated with the occurrence of complications, with an area under the ROC curve of 0.74 (95% CI: 0.64-0.85). The association remained even after adjustment for Mayo risk score (HR: 2.85; 95% CI: 1.46-5.54; p < 0.01), as shown in the Cox proportional hazard model. CONCLUSIONS Decreased platelet count is a predictive factor for PBC-related complications. A cut-off value of ≤ 132.5 × 10(9)/L is recommended for the baseline platelet count to predict complications in patients newly diagnosed with PBC and treated with UDCA.

[PMID: 23058320 DOI: 10.1053/j.gastro.2012.10.001] [Citation(s) in RCA: 342] [Impact Index Per Article: 31.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2012] [Revised: 09/27/2012] [Accepted: 10/02/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Noninvasive methods are needed to identify clinically significant portal hypertension (CSPH) and esophageal varices (EVs) in patients with compensated cirrhosis. We looked for markers of the presence of CSPH and EVs in patients with cirrhosis. METHODS We performed a cross-sectional study that included a training set of 117 patients with compensated cirrhosis, confirmed by histology, from a tertiary referral center. Spleen diameter was measured by ultrasound, and liver stiffness (LS) was measured by transient elastography; endoscopy was used as the standard for detection of EVs, and measurements of hepatic venous pressure gradient were used as the standard for identifying CSPH. We assessed the ability of platelet count, spleen diameter, LS, and combinations of these factors (ie, ratio of platelet count to spleen size, and LS × spleen size/platelet count [LSPS]) to identify patients with CSPH and EV. The analysis included 2 new statistical models: the PH risk score and the varices risk score. Results were validated using an independent series of 56 patients with compensated patients from another center. RESULTS LS was the best single noninvasive variable for identifying patients with CSPH (area under the receiver operating characteristic, 0.883; 95% confidence interval [CI], 0.824-0.943; P < .0001). The area under the receiver operating characteristic value increased when LS was combined with platelet count and spleen size, either as LSPS (0.918; 95% CI, 0.872-0.965; P < .0001) or PH risk score (0.935; 95% CI, 0.893-0.977; P < .0001). More than 80% of patients were accurately classified using LSPS and PH risk score. Analyses of the varices risk score and LSPS were superior to all other noninvasive tests for identifying patients with EVs (area under the receiver operating characteristic, 0.909; 95% CI, 0.841-0.954 and 0.882; 95% CI, 0.810-0.935, respectively); they correctly classified 85% of patients in the training set and 75% in the validation set. CONCLUSIONS Combined data on LS, spleen diameter, and platelet count can be used to identify patients with compensated cirrhosis most likely to have CSPH and EV.

Abstract
Background/Aims The aim of this study was to identify the parameters that could noninvasively predict the presence of esophageal/gastric varices and portal hypertensive gastropathy (PHG) in patients with chronic liver disease (CLD), and to determine the accuracy of those parameters. Methods We retrospectively analyzed 232 patients with CLD who underwent both upper endoscopy and liver CT within an interval of 3 months. The multidimensional index (M-Index) for spleen volume was obtained from the multiplication of splenic length, width, and thickness, as measured by computer tomography. Results The multivariate analysis revealed that platelet, albumin, and M-Index were independently associated with the presence of varices and PHG. We combined three independent parameters, and developed a varices and portal hypertensive gastropathy (VAP) scoring system (=[platelet count (/mm3)×albumin (g/dL)]/[M-Index (cm3)]). The area under the receiver operating characteristic curve of the VAP score was 0.850 (95% confidence interval, 0.801-0.899). The VAP cut-off value of 861 had a sensitivity of 85.3%, a positive likelihood ratio of 3.17, and a negative predictive value of 86.4%. For predicting high-risk lesions for bleeding, with a cut-off value of 861 the sensitivity was 92.0%, the positive likelihood ratio was 2.20, and the negative predictive value was 96.4%. Conclusions The VAP score can predict the presence of varices and PHG in patients with CLD and may increase the cost-benefit of screening endoscopy in the clinical practice setting. A prospective validation study is necessary in the future.

Abstract
AIM To assess the diagnostic accuracy of the platelet count/spleen diameter ratio for identification of oesophageal varices and/or hypertensive gastropathy in patients with compensated cirrhosis. METHODS Platelet count/spleen diameter ratio was calculated in 87 consecutive patients with compensated cirrhosis. A new cut-off with the highest sensitivity and specificity for the presence/absence of oesophageal varices and/or hypertensive gastropathy was identified. Performance of the platelet count/spleen diameter ratio considering previously reported cut-off values were then tested in our population. RESULTS A platelet count/spleen diameter ratio <936.4 had the best sensitivity and specificity for the diagnosis of oesophageal varices and for all endoscopic findings of portal hypertension. A value lower than 936.4 allowed identification of 64.5% of patients with oesophageal varices and 66.7% of patients with any sign of portal hypertension; a value higher than 936.4 excluded oesophageal varices in 64.3% of patients and any sign of portal hypertension in 68.6% of patients. CONCLUSIONS In patients with compensated cirrhosis, the platelet count/spleen diameter ratio is not a useful parameter to avoid unnecessary upper endoscopy, independently of the cut-off.

Abstract
Current guidelines recommend that all cirrhotic patients should undergo screening endoscopy at diagnosis to identify patients with varices at high risk of bleeding who will benefit from primary prophylaxis. This approach places a heavy burden upon endoscopy units and the repeated testing over time may have a detrimental effect on patient compliance. Noninvasive identification of patients at highest risk for oesophageal varices would limit investigation to those most likely to benefit. Upper GI endoscopy is deemed to be the gold standard against which all other tests are compared, but is not without its limitations. Multiple studies have been performed assessing clinical signs and variables relating to liver function, variables relating to liver fibrosis, and also to portal hypertension and hypersplenism. Whilst some tests are clearly preferable to patients, none appear to be as accurate as upper GI endoscopy in the diagnosis of oesophageal varices. The search for noninvasive tests continues.

Abstract
BACKGROUND & AIMS The validation of noninvasive tests to diagnose esophageal varices is a priority in children because repeated endoscopic evaluations are too invasive. We measured the ability of a previously developed noninvasive clinical prediction rule (CPR) to predict the presence of esophageal varices in children. METHODS We analyzed data from 108 children, younger than age 18, who received endoscopies at 8 centers, to assess portal hypertension from chronic liver disease or portal vein obstruction. Blood test and abdominal ultrasound scan results were obtained within 4 months of endoscopy. Grading of varices identified by endoscopy was confirmed by independent blinded review. Spleen size, based on data from the ultrasound scan, was expressed as a standard deviation score relative to normal values for age. RESULTS Of the children studied, 74 had esophageal varices (69%), including 35 with large varices (32%). The best noninvasive predictors of esophageal varices of any size were as follows: platelet:spleen size z-score ratio (area under the receiver operating characteristic curve [AUROC], 0.84; 95% confidence interval [CI] 0.75-0.93), CPR (AUROC, 0.80; 95% CI, 0.70-0.91), and platelet count (AUROC, 0.79; 95% CI, 0.69-0.90). The positive predictive values for the CPR and platelet count were 0.87 and 0.86, the negative predictive values were 0.64 and 0.63, the positive likelihood ratios were 3.06 and 2.76, and the negative likelihood ratios were 0.64 and 0.63, respectively. Based on positive and negative predictive values, the most accurate noninvasive tests were the CPR and platelet counts. CONCLUSIONS Noninvasive tests such as CPR and platelet count can assist in triaging children for endoscopy to identify esophageal varices.

Abstract
Patients with cirrhosis can have abnormalities in laboratory tests reflecting changes in primary haemostasis, including bleeding time, platelet function tests, markers of platelet activation, and platelet count. Such changes have been considered particularly relevant in the bleeding complications that occur in cirrhosis. However, several studies have shown that routine diagnostic tests, such as platelet count, bleeding time, PFA-100, thromboelastography are not clinically useful to stratify bleeding risk in patients with cirrhosis. Moreover, treatments used to increase platelet count or to modulate platelet function could potentially do harm. Consequently the optimal management of bleeding complications is still a matter of discussion. Moreover, in the last two decades there has been an increased recognition that not only bleeding but also thrombosis complicates the clinical course of cirrhosis. Thus, we performed a literature search looking at publications studying both qualitative and quantitative aspects of platelet function to verify which primary haemostasis defects occur in cirrhosis. In addition, we evaluated the contribution of qualitative and quantitative aspects of platelet function to the clinical outcome in cirrhosis and their therapeutic management according to the data available in the literature. From the detailed analysis of the literature, it appears clear that primary haemostasis may not be defective in cirrhosis, and a low platelet count should not necessarily be considered as an automatic index of an increased risk of bleeding. Conversely, caution should be observed in patients with severe thrombocytopenia where its correction is advised if bleeding occurs and before invasive diagnostic and therapeutic procedures.

Abstract
Many people who have cirrhosis are undiagnosed. The diagnosis may not become evident until they develop multiorgan failure after an invasive procedure. Patients with cirrhosis are unusually fragile and can be easily harmed and even set into a fatal down-spiral by seemingly innocuous treatments including medications and invasive procedures. There is much confusion regarding the care of these patients. For example, what medications can be used safely to treat pain, what sedatives are safe and effective, which medications are to be avoided, what diet should be prescribed, and which invasive procedures are safe. This paper provides the author's advice regarding clues to the presence of cirrhosis and the dos and do nots in the general care of these patients, based on his 30 years of experience in a liver-failure-focused academic practice.

Abstract
BACKGROUND AND STUDY AIMS Non-invasive predictors of medium/large oesophageal varices (LOVs) could reduce the number of screening endoscopies. As portal hypertension is a consequence of liver fibrosis, serum fibrosis markers were evaluated together with other variables as possible non-invasive predictors of medium OV/LOV. PATIENTS AND METHODS A total of 154 cirrhotic patients with splenomegaly and 30 healthy control subjects were recruited in a prospective study in two gastroenterology centres in Upper Egypt. Clinical parameters assessed included Child-Pugh class, liver size and ascites. Laboratory parameters included complete blood count, liver function tests, and aspartate aminotransferase (AST)/platelet ratio. Transforming growth factor-β(1) (TGF-β(1)), alpha(2) macroglobulin (A(2)M) and hyaluronic acid (HA) were assayed. Ultrasonographic examination was done for assessment of liver span, portal vein diameter and detection of minimal ascites. Oesophageal varices were diagnosed and graded by oesophagogastroduodenoscopy. RESULTS Fifty-four patients (35%) had no or small varices and 100 (65%) patients had medium OV/LOV by endoscopy. On multivariate analysis, the independent predictors of medium OV/LOV were the presence of ascites (β=0.258, p=0.047) and serum HA (β=0.449, p=0.009). The receiver operating characteristic curve for HA showed the area under the curve to be 0.916. The sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of HA at a cut-off value of 207μgl(-1) were 94%, 77.8%, 88.7%, 87.5% and 88.3%, respectively. CONCLUSIONS The presence of ascites and serum HA level higher than 207μgl(-1) can predict the presence of medium OV/LOV in cirrhotic patients. This would help physicians to identify patients who would most likely benefit from screening endoscopy and thus, reduce costs and discomfort from unnecessary endoscopic procedures.

Abstract
Background Chronic HCV is one of the major causes of morbidity and mortality in the present day world. The assessment of disease progression not only provides useful information for diagnosis and therapeutic supervision judgment but also for monitoring disease. Different invasive and non invasive methods are applied to diagnose the disease from initial to end stage (mild fibrosis to cirrhosis). Although, liver biopsy is still considered as gold standard to identify liver histological stages, an assessment of the disease development based on non-invasive clinical findings is also emerging and this may replace the need of biopsy in near future. This review gives brief insight on non-invasive methods currently available for predicting liver fibrosis in HCV with their current pros and cons to make easier for a clinician to choose better marker to assess liver fibrosis in HCV infected patients. Methods More than 200 studies regarding invasive and noninvasive markers available for HCV liver disease diagnosis were thoroughly reviewed. We examined year wise results of these markers based on their sensitivity, specificity, PPV, NPV and AUROCs. Results We found that in all non-invasive serum markers for HCV, FibroTest, Forn's Index, Fibrometer and HepaScore have high five-year predictive value but with low AUROCs (0.60~0.85) and are not comparable to liver biopsy (AUROC = 0.97). Even though from its beginning, Fibroscan is proved to be best with high AUROCs (> 0.90) in all studies, no single noninvasive marker is able to differentiate all fibrosis stages from end stage cirrhosis. Meanwhile, specific genetic markers may not only discriminate fibrotic and cirrhotic liver but also differentiate individual fibrosis stages. Conclusions There is a need of marker which accurately determines the stage based on simplest routine laboratory test. Genetic marker in combination of imaging technique may be the better non invasive diagnostic method in future.

Abstract
Severe portal hypertension is responsible for complications and death. Although measurement of the hepatic venous pressure gradient is the most accurate method for evaluating the presence and severity of portal hypertension, this technique is considered invasive and is not routinely performed in all centers. Several noninvasive techniques have been proposed to measure portal hypertension. Certain methods evaluate elements related to the pathogenesis of portal hypertension through the measurement of hyperkinetic syndrome, for example, or they investigate the development of hepatic fibrosis through the measurement of increased intrahepatic vascular resistance. Other methods evaluate the clinical consequences of portal hypertension, such as the presence of esophageal varices or the development of portosystemic shunts. Methods evaluating increased hepatic vascular resistance are fairly accurate and mainly involve the detection of hepatic fibrosis by serum markers and transient elastography. The radiological assessment of hyperkinetic syndrome probably has value but is still under investigation. The assessment of severe portal hypertension by the presence of varices may be performed with simple tools such as biological assays, computed tomography, and esophageal capsules. More sophisticated procedures seem promising but are still under development. Screening tools for large populations must be simple, whereas more complicated procedures could help in the follow-up of already diagnosed patients. Although most of these noninvasive methods effectively identify severe portal hypertension, methods for diagnosing moderate portal hypertension need to be developed; this shows that further investigation is needed in this field.

Abstract
BACKGROUND/AIM In patients with liver cirrhosis, the platelet count/spleen diameter ratio has been validated as a parameter for the noninvasive diagnosis of esophageal varices. Schistosoma infection is a frequent cause of portal hypertension in Middle Eastern countries, and is associated with the development of esophageal varices. In this study we aimed to evaluate the platelet count/spleen diameter ratio as a noninvasive tool for the prediction of the presence of esophageal varices in patients with schistosoma-related chronic liver disease. PATIENTS AND METHODS Forty-three patients with hepatosplenic schistosomiasis underwent upper digestive endoscopy to check for the presence of esophageal varices. Furthermore, all patients underwent abdominal ultrasonography, and maximum spleen diameter (in mm) was measured. The platelet count/spleen diameter ratio was calculated in all patients. RESULTS Esophageal varices were found in 31 patients (72%). Age and gender were not significantly different between patients with and without varices. In patients with varices, median platelet count (82,000/μL versus 172,000/μL, P < 0.0001) and platelet count/spleen diameter ratio (571 versus 1651, P < 0.0001) were significantly lower, while spleen diameter (147 mm versus 109 mm, P = 0.0006) was significantly larger. In multivariate analysis, the platelet count/spleen diameter ratio was the only parameter independently associated with the presence of varices (P < 0.0001). CONCLUSIONS In this study we have validated the use of the platelet count/spleen diameter ratio for the noninvasive diagnosis of esophageal varices in patients with portal hypertension caused by schistosoma infection. In these patients, the platelet count/spleen diameter ratio might be used to allow better rationalization of medical resources and use of endoscopy.

Abstract
BACKGROUND/AIM Current guidelines recommend screening cirrhotic patients with an endoscopy to detect esophageal varices and to institute prophylactic measures in patients with large esophageal varices. In this study, we aimed at identifying non-endoscopic parameters that could predict the presence and grades of esophageal varices. PATIENTS AND METHODS In a prospective study, 229 newly diagnosed patients with liver cirrhosis, without a history of variceal bleeding, were included. Demographic, clinical, biochemical and ultrasonographic parameters were recorded. Esophageal varices were classified as small and large, at endoscopy. Univariate analysis and multivariate logistic regression analysis were done to identify independent predictors for the presence and grades of varices. RESULTS Of the 229 patients (141 males; median age 42 years; range 17-73 years) with liver cirrhosis, 97 (42.3%) had small and 81 (35.4%) had large varices. On multivariate analysis, low platelet count (Odd's Ratio [OR], 4.3; 95% confidence interval [CI], 1.2-14.9), Child Pugh class B/C (OR, 3.3; 95% CI, 1.8-6.3), spleen diameter (OR, 4.3; 95% CI, 1.6-11.9) and portal vein diameter (OR, 2.4; 95% CI, 1.1-5.3) were independent predictors for the presence of varices. Likewise, for the presence of large esophageal varices, low platelet count (OR, 2.7; 95% CI, 1.4-5.2), Child Pugh class B/C (OR, 3.8; 95% CI, 2.3-6.5) and spleen diameter (OR, 3.1; 95% CI, 1.6-6.0) were the independent risk factors. CONCLUSION The presence and higher grades of varices can be predicted by a low platelet count, Child-Pugh class B/C and spleen diameter. These may be considered as non-endoscopic predictors for the diagnosis and management of large grade varices.

Abstract
GOALS To assess whether the platelet count/spleen diameter ratio is a useful noninvasive predictor of esophageal varices. BACKGROUND Current guidelines recommend that all patients with cirrhosis undergo screening endoscopy for the presence of varices. Recent studies have focused on using noninvasive techniques to stratify cirrhotic patients according to their risk of having varices. One study examining the platelet count/spleen diameter ratio using a cut-off value of 909, yielded a negative predictive value of 100% for the presence of varices. STUDY A retrospective analysis of 137 patients with cirrhosis over the age of 18 that underwent screening endoscopy for varices between January 2003 and October 2005. The data collected were age, sex, etiology of cirrhosis, spleen diameter, prothrombin time/international normalized ratio, total bilirubin, platelet count, albumin, Child-Pugh score, and endoscopic findings. RESULTS There were 137 patients with 87 (63.5%) men and a mean age of 56 years. Seventy-six (55%) patients had esophageal varices. The mean age, sex, and etiology of cirrhosis were similar between those with and without varices. Using a platelet count/spleen diameter ratio with a cut-off value of 909, yielded a negative predictive value of only 73% and a positive predictive value of 74%. CONCLUSIONS The platelet count/spleen diameter ratio with a cut-off value of 909 may not be sufficiently accurate in predicting the presence of esophageal varices. Upper endoscopy remains the method of choice to screen for the presence of varices.
