A Multicenter International Retrospective Investigation Assessing the Prognostic Role of Inflammation-Based Scores (Neutrophil-to-Lymphocyte, Lymphocyte-to-Monocyte, and Platelet-to-Lymphocyte Ratios) in Patients with Intermediate-Stage Hepatocellular Carcinoma (HCC) Undergoing Chemoembolizations of the Liver. Cancers (Basel) 2024; 16:1618. [PMID: 38730572 PMCID: PMC11083312 DOI: 10.3390/cancers16091618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/14/2024] [Accepted: 04/20/2024] [Indexed: 05/13/2024] Open
Abstract
BACKGROUND The utilization of inflammation-based scores, such as the Neutrophil-to-Lymphocyte Ratio (NLR), Lymphocyte-to-Monocyte Ratio (LMR), and Platelet-to-Lymphocyte Ratio (PLR), has garnered attention for their potential as prognostic indicators in various cancers. However, their predictive role in patients with intermediate-stage HCC undergoing transcatheter arterial chemoembolization (TACE) remains an area that requires further investigation, as early recognition of TACE refractoriness holds the potential to guide tailored therapeutic interventions. METHODS This multicenter international retrospective study analyzed data from patients with intermediate-stage HCC undergoing TACE between 2018 and 2024. Inflammation-based scores (NLR, LMR, PLR) were assessed preoperatively to predict treatment outcomes. RESULTS Two hundred and fourteen patients were enrolled. Preoperative LMR showed the largest area under the curve for the prediction of 6-months PFS, based on the ROC curve analysis. Both high LMR (≥2.24) and low NLR (<4.72) were associated with improved objective response rates and 6-month progression-free survival. Lymphocyte count emerged as a strong predictor of treatment response in both simple (p < 0.001) and multiple (p < 0.001) logistic regression analyses. CONCLUSIONS This study highlights the prognostic value of inflammation-based scores, particularly LMR and NLR, in predicting the treatment response and short-term outcomes of patients with intermediate-stage HCC undergoing TACE. Future investigations should focus on validating these scores' clinical applicability and assessing their impact on long-term patient survival and therapeutic decision-making.

Abstract
Coagulation management in the patient with cirrhosis has undergone a significant transformation since the beginning of this century, with the concept of a rebalancing between procoagulant and anticoagulant factors. The paradigm that patients with cirrhosis have a greater bleeding tendency has changed, as a result of this rebalancing. In addition, it has brought to light the presence of complications related to thrombotic events in this group of patients. These guidelines detail aspects related to pathophysiologic mechanisms that intervene in the maintenance of hemostasis in the patient with cirrhosis, the relevance of portal hypertension, mechanical factors for the development of bleeding, modifications in the hepatic synthesis of coagulation factors, and the changes in the reticuloendothelial system in acute hepatic decompensation and acute-on-chronic liver failure. They address new aspects related to the hemorrhagic complications in patients with cirrhosis, considering the risk for bleeding during diagnostic or therapeutic procedures, as well as the usefulness of different tools for diagnosing coagulation and recommendations on the pharmacologic treatment and blood-product transfusion in the context of hemorrhage. These guidelines also update the knowledge regarding hypercoagulability in the patient with cirrhosis, as well as the efficacy and safety of treatment with the different anticoagulation regimens. Lastly, they provide recommendations on coagulation management in the context of acute-on-chronic liver failure, acute liver decompensation, and specific aspects related to the patient undergoing liver transplantation.

Abstract
Portal hypertension contributes to splenomegaly in cirrhotic patients. Reduction in spleen size may represent improvement in portal hypertension. The goal was to determine whether reduction in spleen size following sustained virologic response (SVR) in patients with hepatitis C virus (HCV) cirrhosis is associated with lower risk of liver-related adverse outcomes. A retrospective cohort study was performed regarding HCV-infected patients treated with direct-acting antiviral agents at the Iowa City Veterans Administration Medical Center between 2014 and 2019. Patients with cirrhosis and splenomegaly on baseline ultrasound were included. Spleen size, platelet counts, decompensations, hepatocellular carcinoma (HCC) status, and mortality were recorded through July 31, 2021. Decrease in spleen size ≥1.5 cm was regarded as significant. Intergroup comparisons were performed on SPSS 28. Eighty patients with cirrhosis and splenomegaly before SVR were identified. Spleen sizes decreased significantly after SVR in 31 patients over a median of 1 year (Group A), whereas 49 patients did not meet this endpoint (Group B). Lack of spleen size reduction was associated with the presence of varices before SVR (odds ratio (OR): 5.3, p < 0.01). Group A had significantly greater increases in platelet count after SVR than did Group B. Patients in Group B had greater risk of HCC (OR: 9.7, CI: 1.2-79; p = 0.03) and death (OR: 3.6, CI: 1.1-12; p = 0.04). Reduced spleen size in patients with HCV cirrhosis after SVR is associated with greater increment in platelet count, decreased risk of HCC, and reduced mortality compared to patients whose spleen size does not decrease.

Abstract
Abnormal bleeding in patients with liver disease may result from elevated portal pressure and varix formation, reduced hepatic synthesis of coagulation proteins, qualitative platelet dysfunction, and/or thrombocytopenia. Major mechanisms of thrombocytopenia in liver disease include splenic sequestration and impaired platelet production due to reduced thrombopoietin production. Alcohol and certain viruses may induce marrow suppression. Immune thrombocytopenia (ITP) may co-occur in patients with liver disease, particularly those with autoimmune liver disease or chronic hepatitis C. Drugs used for the treatment of liver disease or its complications, such as interferon, immunosuppressants, and antibiotics, may cause thrombocytopenia. Periprocedural management of thrombocytopenia of liver disease depends on both individual patient characteristics and the bleeding risk of the procedure. Patients with a platelet count higher than or equal to 50 000/µL and those requiring low-risk procedures rarely require platelet-directed therapy. For those with a platelet count below 50 000/µL who require a high-risk procedure, platelet-directed therapy should be considered, especially if the patient has other risk factors for bleeding, such as abnormal bleeding with past hemostatic challenges. We often target a platelet count higher than or equal to 50 000/µL in such patients. If the procedure is elective, we prefer treatment with a thrombopoietin receptor agonist; if it is urgent, we use platelet transfusion. In high-risk patients who have an inadequate response to or are otherwise unable to receive these therapies, other strategies may be considered, such as a trial of empiric ITP therapy, spleen-directed therapy, or transjugular intrahepatic portosystemic shunt placement.

Abstract
BACKGROUND Posthepatectomy liver failure (PHLF) is a life-threatening complication following hepatic resection. The aspartate aminotransferase-to-platelet ratio index (APRI) is a non-invasive model for assessing the liver functional reserve in patients with hepatocellular carcinoma (HCC). This study aimed to establish a scoring model to stratify patients with HCC at risk for PHLF. METHODS This single-center retrospective study included 451 patients who underwent hepatic resection for HCC between 2004 and 2017. Preoperative factors, including non-invasive liver fibrosis markers and intraoperative factors, were evaluated. The predictive impact for PHLF was evaluated using receiver operating characteristic (ROC) curves of these factors. RESULTS Of 451 patients, 30 (6.7%) developed severe PHLF (grade B/C). Multivariate logistic analysis indicated that APRI, model for end-stage liver disease (MELD) score, operating time, and intraoperative blood loss were significantly associated with severe PHLF. A scoring model (over 0-4 points) was calculated using these optimal cutoff values. The area under the ROC curve of the established score for severe PHLF was 0.88, which greatly improved the predictive accuracy compared with these factors alone (p < 0.05 for all). CONCLUSIONS The scoring model-based APRI, MELD score, operating time, and intraoperative blood loss can predict severe PHLF in patients with HCC.

Abstract
Introduction Thrombocytopenia is common in critically ill trauma patients and can lead to potentially broad differentials, including major bleeding, hemodilution, extracorporeal circuit losses, heparin-induced thrombocytopenia, and more. Understanding the normal time course of platelet decline and recovery may delineate thrombocytopenia(HIT) secondary to traumatic injury versus other inciting factors. Methods This retrospective study included trauma patients admitted over a 1-year period. The primary aim was characterizing the effect of trauma on platelet concentration and thrombocytopenia incidence in the first 30 days following injury. Thrombocytopenia was defined as platelet concentration <150 × 109/L. A secondary aim was evaluating significant factors contributing to thrombocytopenia. Results A total of 225 patients were included. Thrombocytopenia occurred in 67.3% of patients, and a platelet decline of 50% or greater occurred in 44%. Decrease in platelet concentration was significant from day 1 to day 4 (mean ± SD, 232 ± 86 vs 142 ± 76 × 109/L; p = .001). Platelets recovered to baseline on day 8 and peaked on day 16. Packed red blood cell or platelet transfusion, continuous renal replacement therapy, and acute liver injury independently predicted a ≥50% platelet decrease. HIT was not diagnosed in any patients. Conclusion Platelet nadir likely occurs approximately 4 days after injury and recovers relatively quickly thereafter. More studies are needed to evaluate the magnitude of effect on thrombocytopenia by factors beyond trauma.

Abstract
Plasma thrombopoietin (TPO) measurements help distinguish between different types of thrombocytopenia but are not feasible in routine clinical practice. We developed a fully automated quantitative chemiluminescent enzyme immunoassay (CLEIA) for measuring TPO (TPO-CLEIA), which is a one-step sandwich-type assay. This assay utilizes a mouse monoclonal capture antibody, which has the neutralizing epitope of the interaction between TPO and the TPO receptor, and a newly generated rabbit monoclonal detector antibody. In analytical performance studies, this assay showed good linearity over the measuring range and high sensitivity. The limit of quantification (LoQ) of this assay was 3.4 pg/mL; low TPO concentration values of almost all healthy individuals exceeded the LoQ value. In clinical validation studies, TPO levels obtained from patients with aplastic anemia (AA) significantly increased, whereas those of patients with immune thrombocytopenia (ITP) were normal or slightly increased. The cutoff value for TPO-CLEIA corresponding to the previously reported values was useful for distinguishing between ITP and AA. These results suggest that TPO-CLEIA can quantify human plasma TPO levels with high accuracy and sensitivity and has the potential to facilitate routine clinical measurement of TPO in patients with various types of thrombocytopenia.

Abstract
PURPOSE Inflammation-, nutrition-, and liver fibrosis-related markers are recognized as prognostic for hepatocellular carcinoma (HCC) patients. This study, therefore, assessed the preoperative prognostic utility of the combination of these markers in patients with HCC. METHODS This single-center retrospective study included patients who underwent hepatic resection for HCC between 2004 and 2017. A total of 454 patients were divided into training (n = 334) and validation (n = 120) cohorts by random sampling. The predictive impact on surgical outcomes was evaluated using receiver operating characteristic (ROC) curves of these prognostic values in the training cohort. RESULTS The prognostic nutritional index (PNI) and aspartate aminotransferase-to-platelet ratio index (APRI) were the strongest diagnostic values (areas under the ROC curves: 0.627 and 0.646, respectively). A scoring system (over 0-2 points) was developed using optimal cutoff values (for PNI < 46.5 scored as 1 point; for APRI > 0.98 scored as 1 point). An increased PNI-APRI score was an independent prognostic factor for both the overall and disease-free survival in HCC patients. Finally, the clinical feasibility of the PNI-APRI score was confirmed in the validation cohort. CONCLUSIONS The PNI-APRI score is a useful marker for predicting surgical outcomes of HCC patients.

Abstract
Information on the stage of liver cirrhosis is essential for prognostication and decisions on surgical planning for hepatocellular carcinoma (HCC) patients. But a non-invasive liver cirrhosis staging model is still lacking. The aim of our study was to develop a non-invasive model based on routine clinical parameters to evaluate the severity of cirrhosis in hepatitis B related HCC patients. A total of 226 HCC patients with chronic hepatitis B virus (HBV) infection who had liver resection were analyzed in this retrospective study. We found that platelets, prothrombin activity, maximum oblique diameter of right hepatic lobe and spleen length were the independent predictors of liver cirrhosis in HCC patients. By cumulating the weight of risk scores of independent variables, we constructed the PPMS (PLT/PTA/maximum oblique diameter of right hepatic lob/spleen length) index. The areas under the receiver operating characteristic curves (AUROC) of PPMS index were 0.820, 0.667, and 0.650 in predicting ≥cirrhosis 1 (C1), ≥cirrhosis 2 (C2), and ≥cirrhosis 3 (C3), respectively. The optimal cut-off value of the PPMS index for predicting ≥C1, ≥C2, and ≥C3 was 4.392, 4.471, and 4.784, respectively. And the corresponding sensitivity was 63.1%, 63.2%, and 64.7%, the corresponding specificity was 89.4%, 64.3%, and 62.5%, respectively. Our study constructed a non-invasive liver cirrhosis index (PPMS) could distinguish patients from different stages of liver cirrhosis, which might add more preoperative information for HCC patients.

A newly devised flow cytometric antibody binding assay helps evaluation of dithiothreitol treatment for the inactivation of CD38 on red blood cells. Vox Sang 2020; 116:725-734.

Abstract
BACKGROUND AND OBJECTIVES Anti-CD38 monoclonal antibodies, including daratumumab and isatuximab, often interfere with pretransfusion testing. Dithiothreitol (DTT) treatment of red blood cells (RBCs) negates this interference. However, the optimum DTT concentration and treatment time have not been well defined. Here, we quantified CD38 on RBCs before and after DTT treatment using a flow cytometric antibody binding assay (FABA) to specify the optimum conditions for CD38 inactivation. MATERIALS AND METHODS For FABA, untreated or DTT-treated RBCs were incubated with fluorescein isothiocyanate-labelled anti-CD38 antibody, in the presence or absence of 100-fold or more excess of unlabelled anti-CD38 antibody, and then analysed by flow cytometry (FCM). Dissociation of CD38-positive and control histograms was determined from the D-value using the Kolmogorov-Smirnov test. The results from FABA were compared with those from conventional FCM, indirect antiglobulin test (IAT) and Western blotting. RESULTS The results from FABA were more consistent than those from conventional FCM. The D-value was found to be reliable in the analysis of difference between CD38 before and after DTT treatment. Our data showed that 0·0075 mol/l DTT for 30 min is sufficient to inactivate CD38 on RBCs. These results were stable and consistent with the findings from IAT. CONCLUSION Flow cytometric antibody binding assay is an objective way of evaluating the efficacy of DTT treatment for CD38 on RBCs. This approach allows the detection of a small number of cell surface antigens and will be useful for assessing the various chemical treatments to denature RBC antigens.

Abstract
Noninvasive tests for the assessment of liver fibrosis are highly needed for the management of patients with autoimmune hepatitis (AIH). We aimed to investigate the accuracy of red cell distribution width to platelet ratio (RPR) in predicting liver fibrosis in AIH patients. One hundred nineteen AIH patients who underwent liver biopsy were enrolled. Liver fibrosis stage was diagnosed using the Scheuer scoring system. The diagnostic accuracy was evaluated by the area under the receiver operating characteristic curve (AUROC). RPR values in AIH patients with S2-S4 (0.10, interquartile range [IQR] 0.08-0.15), S3-S4 (0.10, IQR 0.09-0.14), and S4 (0.14, IQR 0.09-0.19) were significantly higher than patients with S0-S1 (0.07, IQR 0.06-0.08, P < .001), S0-S2 (0.08, IQR 0.06-0.12, P = .025) and S0-S3 (0.09, IQR 0.07-0.13, P = .014), respectively. The RPR was positively correlated with fibrosis stages (r = 0.412, P < .001), while aspartate transaminase to platelet ratio index (APRI) and fibrosis-4 score (FIB-4) were not significantly associated with fibrosis stages in AIH patients. The AUROCs of RPR in identifying significant fibrosis (S2-S4), advanced fibrosis (S3-S4), and cirrhosis (S4) were 0.780 (95% confidence interval [CI] 0.696-0.865), 0.639 (95% CI 0.530-0.748), and 0.724 (95% CI 0.570-0.878), respectively. The AUROCs of RPR were significantly higher than APRI and FIB-4 in diagnosing significant fibrosis, advanced fibrosis, and cirrhosis. Our study demonstrates that the RPR is a simple predictor of liver fibrosis and is superior to APRI and FIB-4 in identifying liver fibrosis in AIH patients.

Platelet indices significantly correlate with liver fibrosis in HCV-infected patients. PLoS One 2020; 15:e0227544.

Abstract
AIM A total of 241 patients with chronic HCV infection were recruited to investigate the association between liver fibrosis and PLT counts, as well as with MPV, PDW and P-LCR indices. METHODS The determination of PLT indices was carried out using a Sysmex XT-1800i automated hematology analyzer. Serological tests for HA, LN, C-IV and PIIINP were performed in 210 patients. The liver stiffness was measured in 69 patients by transient elastography (FibroScan). RESULTS The analysis showed that the four serum fibrosis markers were negatively correlated with PLT counts, but positively correlated with the MPV, PDW and P-LCR values. Moreover, a similar pattern was found after analyzing the FibroScan measurements, which were negatively correlated with PLT counts, but positively correlated with MPV, PDW and P-LCR values. We subdivided the HCV-infected patients into mild and advanced fibrosis groups. The PLT counts were significantly decreased and the MPV, PDW and P-LCR values were significantly increased in the advanced fibrosis group when compared with the mild fibrosis group. CONCLUSIONS Our results demonstrate that not only the PLT counts but also the MPV, PDW and P-LCR indices significantly correlate with liver fibrosis in HCV-infected patients. Therefore, these indices may be useful laboratory measures for evaluating liver fibrosis progression.

Management of Thrombocytopenia in Patients with Chronic Liver Disease. Dig Dis Sci 2019; 64:2757-2768.

Abstract
BACKGROUND Thrombocytopenia is the most common hematologic complication associated with chronic liver disease (CLD) with important clinical implications. While the mechanisms for thrombocytopenia are multifactorial, platelet sequestration in the spleen and decreased thrombopoietin (TPO) production are the main mechanisms in patients with CLD. AIM This review outlines the current treatment options for thrombocytopenia in patients with CLD, explores their limitations, and proposes a revised treatment algorithm for the management of thrombocytopenia in this patient group. METHODS A PubMed search of the literature was undertaken with search terms focused on CLD and thrombocytopenia. RESULTS Until now, the standard-of-care treatment in these patients has been the use of platelet transfusions either prophylactically or periprocedurally to control bleeding. Treatment options, such as splenic artery embolization and splenectomy, are invasive, and their utility is limited by significant complications. The US Food and Drug Administration recently approved 2 s-generation TPO-receptor agonists, avatrombopag and lusutrombopag, as safe and effective therapies for the treatment of thrombocytopenia in patients with CLD scheduled to undergo a procedure. CONCLUSIONS The addition of avatrombopag and lusutrombopag offers physicians an alternative to platelet transfusions in patients with CLD who have to undergo medical/dental procedures that could potentially put them at an increased risk of bleeding. There are several other drugs in the research pipeline at various stages of development, including a new class of monoclonal antibodies that can bind to and activate TPO-receptor agonists. The outlook for treatment choices for thrombocytopenia in patients with liver disease is promising.

Abstract
Appropriate diagnostic and therapeutic measures for liver cirrhosis is critical, particularly in children. In the present review, a comprehensive approach was provided toward hematological parameters in pediatric liver cirrhosis. The literature search included MeSH terms "liver cirrhosis" and "hepatic cirrhosis" and databases such as PubMed, Web of Science, Scopus, and Google Scholar were searched up until December 2017. Hematologic changes in the liver cirrhosis mainly encompassed anemia and coagulopathies. In addition, bleeding diathesis was considered as the most clinical complication in these patients. In addition to reduced coagulation factors, hyperfibrinolysis is a common feature in childhood cirrhosis and may be an important contributor to the risk of bleeding. Based on the results, children with liver cirrhosis also demonstrated a procoagulant state at laboratory and clinical levels. This may be partly due to a reduction in coagulation inhibitors such as anti-thrombin, C1 inhibitor, and α1-antitrypsin in children with cirrhosis. The portal vein thrombosis and portal hypertension are considered as the most clinical presentations of the hypercoagulable state. Further, children with liver cirrhosis complicated with portal hypertension usually show leukopenia, anemia, and thrombocytopenia due to hypersplenism. Although the etiology of childhood and adult cirrhosis may be different, their hematological compilations and clinicopathological features are somehow similar.

Abstract
BACKGROUND Liver biopsy is the criterion standard for diagnosing liver fibrosis, but it is not widely used to monitor liver fibrosis because of the invasiveness, risk of complications, and sample errors. Therefore, it is necessary to involve other techniques to monitor liver fibrosis or cirrhosis during clinical practice. The objective was to explore noninvasive indicators to predict advanced liver fibrosis in autoimmune hepatitis (AIH) patients. METHODS A total of 45 AIH patients and 47 healthy controls were recruited to this retrospective study. Complete blood count and liver function tests were performed for all subjects. AIH patients were divided into "no/minimal fibrosis" group and "advanced fibrosis" group based on liver biopsy. RESULTS AIH patients demonstrated significantly higher monocytes, MCV, RDW-CV, RDW-SD, NLR, RDW-CV/PLT, RDW-SD/PLT, TBIL, DBIL, GLB, ALT, AST, GGT, ALP, and GPR and lower WBC, neutrophils, lymphocytes, RBC, HGB, HCT, LMR, TP, ALB, and AAR compared with healthy controls. Patients with advanced fibrosis showed remarkably higher RDW-CV, RDW-SD, RDW-CV/PLT, RDW-SD/PLT, AAR, and FIB-4 and lower RBC, PLT, PCT, and ALB compared with the no/minimal fibrosis group. Logistic regression analysis showed that RDW-SD/PLT was an independent risk factor for advanced fibrosis with an OR (95% CI) of 2.647 (1.383-5.170). Receiver operating characteristic (ROC) analysis revealed that RDW-SD, RDW-CV/PLT, RDW-SD/PLT, FIB-4, and AAR had an area under the ROC curve (AUC) above 0.700 and RDW-SD/PLT had the largest AUC of 0.785 with a cutoff value of 0.239. CONCLUSION RDW-SD, RDW-CV/PLT, RDW-SD/PLT, FIB-4, and AAR were excellent noninvasive biomarkers and RDW-SD/PLT was an independent risk factor for predicting advanced fibrosis in AIH patients.

Abstract
The Ishak scoring system has been used to stage liver fibrosis. Ten noninvasive liver reserve models were proposed to assess the severity of liver fibrosis, but their performance in hepatocellular carcinoma (HCC) is unknown. We aimed to evaluate the correlation between these models and severity of fibrosis in patients with HCC. A total 464 patients with HCC undergoing surgical resection were retrospectively analyzed. Multivariate logistic regression analysis was performed to determine independent factors associated with advanced fibrosis (Ishak score 4 or higher). There were no significant correlations between all noninvasive models and severity of fibrosis in HCC (p for trend all >0.1). In subgroup analysis, cirrhosis discriminant index (CDS) and Lok’s index in hepatitis B-, and fibrosis index based on 4 factors (FIB-4), CDS and Lok’s index in hepatitis C-associated HCC, best correlated with the severity of liver fibrosis. Low platelet count, prolonged prothrombin time, hepatitis C and multiple tumors were independently associated with advanced fibrosis. Among the 10 models, CDS was the best model to predict cirrhosis. Currently used noninvasive liver reserve models do not well correlate with severity of histological fibrosis in HCC. New noninvasive models are required to improve the predictive accuracy of liver fibrosis in HCC.

Abstract
Background The production of peripheral platelet is mainly regulated by thrombopoietin, which is a glycoprotein hormone predominantly synthesized in the liver. Previously, many studies have reported that there was an inverse correlation between the degree of chronic viral hepatitis and the peripheral platelet count. However, the effect of nonalcoholic fatty liver disease (NAFLD) on the peripheral platelet counts remains unclear. Methods With 1303 participants from “The prevention of MS and multi-metabolic disorders in Jiangsu province of China (PMMJS)” cohort study, we investigated the associations between NAFLD and the risk of platelet counts reduction in Chinese adults. The paired-samples T test was used to explore the platelet counts changes between baseline and follow-up. Multivariate logistic regression was used to examine the association between presence of NAFLD and the risk of platelet reduction by calculating the odds ratios (ORs) and 95% confidence interval (CI). Results After five years of follow-up, platelet counts were markedly reduced from 220.6 ± 42.22 (109/L) at baseline to 208.41 ± 40.70 (109/L) at follow-up in NAFLD group (P < 0.0001). However, platelet counts were slightly lowered from 213.2 ± 43.26(109/L) at baseline to 211.8 ± 41.65 (109/L) at follow-up in non-NAFLD people (P = 0.2349). Meanwhile, there was a significant association between NAFLD and the risks of platelet count reduction, even after adjustment for confounding variables (OR: 1.68, 95% CI: 1.06–2.67). Additionally, among the participants with BMI ≤ 23 kg/m2 and SUA ≤ 344.3 μmol/L, the NAFLD participants have an increased risk of platelet count reduction compared to the persons in non-NAFLD group. Conclusions Our present results suggested that NAFLD individuals have an increased risk of platelet counts reduction.

Non-invasive aspartate aminotransferase to platelet ratio index correlates well with invasive hepatic venous pressure gradient in cirrhosis. Indian J Gastroenterol 2018; 37:335-341. [PMID: 30178093 DOI: 10.1007/s12664-018-0879-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Accepted: 08/03/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND Hepatic venous pressure gradient (HVPG) is the best recommended tool to measure portal pressure, but is invasive. HVPG helps in prognosticating cirrhosis and predict its complications. Aminotransferase to platelet ratio index (APRI) is a simple non-invasive marker of hepatic fibrosis. We aimed to correlate APRI with HVPG and to determine the usefulness of APRI in predicting complication of cirrhosis. METHODS APRI and HVPG were measured in consecutive patients of cirrhosis aged 18 to 70 years. Spearman's rho was used to estimate their correlation; a cut-off value of APRI to predict severe portal hypertension (HVPG > 12 mmHg) was determined. RESULTS This study, conducted between August 2011 and December 2014, included 277 patients, median age 51 (range: 16-90) years, 84% males. Etiology of cirrhosis was alcohol in 135 (49%), cryptogenic/nonalcoholic steatohepatitis (NASH) in 104 (38%), viral in 34 (12%), and others in 4 (1%). Median Child-Turcott-Pugh (CTP) and model for end-stage liver disease (MELD) scores were 7 (5-11) and 11 (6-33), respectively. Median HVPG was 17.0 (1.5-33) mmHg and median APRI was 1.09 (0.21-12.22). There was positive correlation between APRI and HVPG (Spearman's rho 0.450, p < 0.001). The area under the receiver operating characteristic (ROC) curve of APRI for predicting severe portal hypertension was 0.763 (p < 0.01). Youden's index defined the cut-off of APRI for predicting HVPG > 12 mmHg was 0.876 with a sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 71%, 78%, 94%, 38%, and 73%, respectively. APRI also correlated well with CTP, variceal size, bleeding status, ascites but not with MELD. CONCLUSIONS APRI score of 0.876 has an acceptable accuracy to predict severe portal hypertension (HVPG > 12 mmHg). High APRI also correlated with severity of cirrhosis and its complications. Thus, APRI may be used as a simple, bedside, non-invasive, and inexpensive tool for evaluating portal hypertension and complications of cirrhosis.

Preoperatively staging liver fibrosis using noninvasive method in hepatitis B virus-infected hepatocellular carcinoma patients. Oncotarget 2018; 8:4289-4300. [PMID: 28008144 PMCID: PMC5354832 DOI: 10.18632/oncotarget.14024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2016] [Accepted: 12/05/2016] [Indexed: 02/05/2023] Open
Abstract
Background Advanced liver fibrosis can result in serious complications (even patient’s death) after partial hepatectomy. Preoperatively percutaneous liver biopsy is an invasive and expensive method to assess liver fibrosis. We aim to establish a noninvasive model, on the basis of preoperative biomarkers, to predict liver fibrosis in hepatocellular carcinoma (HCC) patients with hepatitis B virus (HBV) infection. Methods The HBV-infected liver cancer patients who had received hepatectomy were retrospectively and prospectively enrolled in this study. Univariate analysis was used to compare the variables of the patients with mild to moderate liver fibrosis and with severe liver fibrosis. The significant factors were selected into binary logistic regression analysis. Factors determined to be significant were used to establish a noninvasive model. Then the diagnostic accuracy of this novel model was examined based on sensitivity, specificity and area under the receiver-operating characteristic curve (AUC). Results This study included 2,176 HBV-infected HCC patients who had undergone partial hepatectomy (1,682 retrospective subjects and 494 prospective subjects). Regression analysis indicated that total bilirubin and prothrombin time had positive correlation with liver fibrosis. It also demonstrated that blood platelet count and fibrinogen had negative correlation with liver fibrosis. The AUC values of the model based on these four factors for predicting significant fibrosis, advanced fibrosis and cirrhosis were 0.79-0.83, 0.83-0.85 and 0.85-0.88, respectively. Conclusion The results showed that this novel preoperative model was an excellent noninvasive method for assessing liver fibrosis in HBV-infected HCC patients.

Abstract
BACKGROUND AND AIMS Thrombocytopenia occurs frequently in patients with cirrhosis. The immature platelet fraction (IPF%) is measured to differentiate the causes of thrombocytopenia. To date the relevance of thrombopoietin (TPO) in the context of cirrhosis is unknown. The aim of our study was to investigate the cause of thrombocytopenia in patients with liver cirrhosis by measuring IPF%, TPO and spleen size. In addition we examined the use of IPF% to evaluate the severity of cirrhosis and its complications. METHODS Overall, we included 88 in-patients with cirrhosis in our study. The collected data comprises current health status, blood parameters, severity of cirrhosis evaluated by Child-Pugh score and MELD score, spleen diameter, ascites and esophageal varices. The IPF% was measured using an automatic hematology analyzer. TPO was measured with ELISA. RESULTS IPF% (p = 0.003) and spleen diameter (p = 0.001) were significantly higher in patients with thrombocytopenia. There was no significant difference in TPO between patients with and without thrombocytopenia. The mean values of IPF% varied significantly (p = 0.044) in Child-Pugh stages. IPF% was significantly (p = 0.005) elevated in patients with esophageal varices. Moreover, IPF% higher than 3.85% displayed sensitivity of 76.6% and specificity of 52.4% with an area under receiver operating curve characteristics of 0.669 for the presence of esophageal varices. CONCLUSION On closer examination of the three compartments known to have an influence on platelet count splenomegaly seems to be the major cause of thrombocytopenia in patients with cirrhosis according to current knowledge. Higher IPF% in patients with thrombocytopenia indicates peripheral consumption of platelets. The relation between spleen diameter and platelet count indicates the spleen to be the major place of platelets' consumption. TPO did not differ between patients with and without thrombocytopenia. Furthermore, we cannot exclude an influence of impaired thrombopoietin synthesis on platelet counts. The association between IPF% and platelet count suggests that there is physiological regulation of platelets in patients with cirrhosis. In our study IPF% is associated with esophageal varices and the stage of cirrhosis. Further studies are needed to confirm these results.

A novel predictive model using routinely clinical parameters to predict liver fibrosis in patients with chronic hepatitis B. Oncotarget 2017; 8:59257-59267. [PMID: 28938634 PMCID: PMC5601730 DOI: 10.18632/oncotarget.19501] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2017] [Accepted: 06/28/2017] [Indexed: 12/19/2022] Open
Abstract
Objectives Noninvasive models have been established for the assessment of liver fibrosis in patients with chronic hepatitis B(CHB). However, the predictive performance of these established models remains inconclusive. We aimed to develop a novel predictive model for liver fibrosis in CHB based on routinely clinical parameters. Results Platelets(PLT), the standard deviation of red blood cell distribution width(RDW-SD), alkaline phosphatase(ALP) and globulin were independent predictors of significant fibrosis by multivariable analysis. Based on these parameters, a new predictive model namely APRG(ALP/PLT/RDW-SD/globulin) was proposed. The areas under the receiver-operating characteristic curves(AUROCs) of APRG index in predicting significant fibrosis(≥F2), advanced fibrosis(≥F3) and liver cirrhosis(≥F4) were 0.757(95%CI 0.699 to 0.816), 0.763(95%CI 0.711 to 0.816) and 0.781(95%CI 0.728 to 0.835), respectively. The AUROCs of the APRG were significantly higher than that of aspartate transaminase(AST) to PLT ratio index(APRI), RDW to PLT ratio(RPR) and AST to alanine aminotransferase ratio(AAR) to predict significant fibrosis, advanced fibrosis and cirrhosis. The AUROCs of the APRG were also significantly higher than fibrosis-4 score (FIB-4) (0.723, 95%CI 0.663 to 0.783) for cirrhosis(P=0.034) and better than gamma-glutamyl transpeptidase(GGT) to PLT ratio(GPR) (0.657, 95%CI 0.590 to 0.724) for significant fibrosis(P=0.001). Materials and Methods 308 CHB patients who underwent liver biopsy were enrolled. The diagnostic values of the APRG for liver fibrosis with other noninvasive models were compared. Conclusions The APRG has a better diagnostic value than conventionally predictive models to assess liver fibrosis in CHB patients. The application of APRG may reduce the need for liver biopsy in CHB patients in clinical practice.

Abstract
AIM To determine incidence and clinical biomarkers of marked necroinflammation and fibrosis characteristics among chronic hepatitis B (CHB) patients with persistently normal alanine aminotransferase (PNALT).
METHODS Liver biopsy was performed on 115 CHB patients with PNALT. Necroinflammation and fibrosis were graded by the Knodell histologic activity index and the Ishak fibrosis score, respectively. Correlations between the available clinical parameters and necroinflammation and fibrosis were analysed.
RESULTS Marked necroinflammation (Knodell activity index ≥ 7) and fibrosis (Ishak fibrosis score ≥ 3) were found in 36.5% and 15.5% of CHB patients with PNALT, respectively. Following a univariate logistic regression analysis, multiple logistic regression analysis indicated that aspartate transaminase (AST) (AUROC = 0.852, cut-off value = 22.5 U/L) serves as an independent predictor of notable liver inflammation, while platelet (PLT) count (AUROC = 0.905, cut-off value = 171.5 ×109/mL) and gamma-glutamyl transpeptidase (GGT) (AUROC = 0.909, cut-off value = 21.5 U/L) level serve as independent predictors of notable liver fibrosis.
CONCLUSION A considerable proportion of marked histological abnormalities existed in our cohort, who will benefit from optimal therapeutic strategies administered according to predictive indication by AST, PLT and GGT levels.

Abstract
The aspartate aminotransferase-to-platelet ratio index has been reported to predict prognosis of patients with hepatocellular carcinoma. This study examined the prognostic potential of stratified aspartate aminotransferase-to-platelet ratio index for hepatocellular carcinoma patients undergoing curative liver resection. A total of 661 hepatocellular carcinoma patients were retrieved and the associations between aspartate aminotransferase-to-platelet ratio index and clinicopathological variables and survivals (overall survival and disease-free survival) were analyzed. Higher aspartate aminotransferase-to-platelet ratio index quartiles were significantly associated with poorer overall survival (p = 0.002) and disease-free survival (p = 0.001). Multivariate analysis showed aspartate aminotransferase-to-platelet ratio index to be an independent risk factor for overall survival (p = 0.018) and disease-free survival (p = 0.01). Patients in the highest aspartate aminotransferase-to-platelet ratio index quartile were at 44% greater risk of death than patients in the first quartile (hazard ratio = 1.445, 95% confidence interval = 1.081 - 1.931, p = 0.013), as well as 49% greater risk of recurrence (hazard ratio = 1.49, 95% confidence interval = 1.112-1.998, p = 0.008). Subgroup analysis also showed aspartate aminotransferase-to-platelet ratio index to be an independent predictor of poor overall survival and disease-free survival in patients positive for hepatitis B surface antigen or with cirrhosis (both p < 0.05). Similar results were obtained when aspartate aminotransferase-to-platelet ratio index was analyzed as a dichotomous variable with cutoff values of 0.25 and 0.62. Elevated preoperative aspartate aminotransferase-to-platelet ratio index may be independently associated with poor overall survival and disease-free survival in hepatocellular carcinoma patients following curative resection.

Hepatitis C virus and human T-cell lymphotropic virus type 1 co-infection: impact on liver disease, virological markers, and neurological outcomes. Int J Infect Dis 2017; 57:116-122.

Abstract
OBJECTIVES Human T-cell lymphotropic virus type 1 (HTLV-1) infection is associated with neurological abnormalities, such as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and peripheral neuropathy (PN). Hepatitis C virus (HCV) infection is the leading cause of chronic liver disease worldwide, and causes PN in approximately 9% of patients. Because the interplay between these potentially neuropathogenic viruses in the same individual is still poorly understood, the clinical and laboratory outcomes of co-infected patients were evaluated and compared with those of controls. METHODS The prevalence rates of neurological and laboratory abnormalities were evaluated in HCV/HTLV-1 co-infected patients (n=50), and in subjects with single HCV (n=46) or HTLV-1 (n=150) infection. RESULTS A higher frequency of isolated PN was present in HCV-infected patients; this was not associated with cryoglobulinemia. No difference was found in the frequency of PN or HAM/TSP when co-infected subjects were compared to singly infected subjects. Hepatic involvement was present in HCV-infected subjects, as shown by increased levels of serum alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, and bilirubin, in addition to thrombocytopenia. On the other hand, HCV/HTLV-1 co-infected individuals presented a better prognosis for hepatic involvement when compared with singly HCV-infected subjects. CONCLUSIONS These data suggest that HCV/HTLV-1 co-infection does not mutualistically alter the outcome with regard to neurological manifestations. Nonetheless, changes in the immunological environment induced by HTLV-1 infection could lead to a reduction in hepatic damage, even without significant HCV clearance.

Abstract
AIM To investigate the diagnostic ability of a non-invasive biological marker to predict liver fibrosis in hepatitis C genotype 4 patients with high accuracy.
METHODS A cohort of 332 patients infected with hepatitis C genotype 4 was included in this cross-sectional study. Fasting plasma glucose, insulin, C-peptide, and angiotensin-converting enzyme serum levels were measured. Insulin resistance was mathematically calculated using the homeostasis model of insulin resistance (HOMA-IR).
RESULTS Fibrosis stages were distributed based on Metavir score as follows: F0 = 43, F1 = 136, F2 = 64, F3 = 45 and F4 = 44. Statistical analysis relied upon reclassification of fibrosis stages into mild fibrosis (F0-F) = 179, moderate fibrosis (F2) = 64, and advanced fibrosis (F3-F4) = 89. Univariate analysis indicated that age, log aspartate amino transaminase, log HOMA-IR and log platelet count were independent predictors of liver fibrosis stage (P < 0.0001). A stepwise multivariate discriminant functional analysis was used to drive a discriminative model for liver fibrosis. Our index used cut-off values of ≥ 0.86 and ≤ -0.31 to diagnose advanced and mild fibrosis, respectively, with receiving operating characteristics of 0.91 and 0.88, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and positive likelihood ratio were: 73%, 91%, 75%, 90% and 8.0 respectively for advanced fibrosis, and 67%, 88%, 84%, 70% and 4.9, respectively, for mild fibrosis.
CONCLUSION Our predictive model is easily available and reproducible, and predicted liver fibrosis with acceptable accuracy.

Abstract
BACKGROUND Aspartate aminotransferase to platelet ratio index (APRI) and the fibrosis index based on four factors (FIB-4) are the two most focused non-invasive models to assess liver fibrosis. AIMS We aimed to examine the validity of these two models for predicting hepatitis B virus (HBV)-related liver fibrosis accompanied with hepatocellular carcinoma (HCC). METHODS We enrolled HBV-infected patients with liver cancer who had received hepatectomy. The accuracy of APRI and FIB-4 for diagnosing liver fibrosis was assessed based on their sensitivity, specificity, diagnostic efficiency, positive predictive value (PPV), negative predictive value (NPV), kappa (κ) value and area under the receiver-operating characteristic curve (AUC). RESULTS Finally 2176 patients were included, with 1682 retrospective subjects and 494 prospective subjects. APRI (rs=0.310) and FIB-4 (rs=0.278) were positively correlated with liver fibrosis. And χ(2) analysis demonstrated that APRI and FIB-4 values correlated with different levels of liver fibrosis with all P values less than 0.01. The AUC values for APRI and FIB-4 were 0.685 and 0.626 (P=0.73) for predicting significant fibrosis, 0.681 and 0.648 (P=0.81) for differentiation of advanced fibrosis and 0.676 and 0.652 (P=0.77) for diagnosing cirrhosis. CONCLUSION APRI and FIB-4 correlate with liver fibrosis. However these two models have low accuracy for predicting HBV-related liver fibrosis in HCC patients.

Abstract
OBJECTIVE Recent studies have demonstrated that surgical menopause results in a significantly increased risk of nonalcoholic fatty liver disease (NAFLD) in women with endometrial cancer. In addition, venous thromboembolism (VTE) is known to be one of the major prognostic factors for decreased survival in endometrial cancer. Given the fact that coagulation factors are produced in the liver, the correlation between NAFLD and VTE was examined in endometrial cancer. METHODS A retrospective study was conducted to examine patients with endometrial cancer who underwent surgical staging including oophorectomy between 2000 and 2013 (n = 714). Cumulative risk of VTE was examined based on the NAFLD status. A Cox proportional hazard regression model was used to determine the independent risk predictors of VTE. RESULTS Venous thromboembolism and NAFLD were seen in 57 (8.0%) and 181 (25.4%) cases, respectively. Two-year cumulative risks of VTE and NAFLD were 7.9% and 19.3%, respectively. In univariate analysis, VTE was significantly associated with decreased disease-free survival (2-year rate, 43.6% vs 91.4%, P < .001) and overall survival (65.8% vs 96.8%, P < .001), whereas NAFLD was associated with decreased risk of VTE (1.7% vs 10.4%, P < .001). In multivariate analysis controlling for clinicopathological factors, NAFLD remained an independent predictor of decreased risk of VTE (hazard ratio [HR]: 0.24, 95% confidence interval [CI]: 0.07-0.79, P = .02). Thrombocytosis (HR: 2.30, 95% CI: 1.22-4.35, P = .01), cancer antigen 125 ≥ 35 (HR: 3.81, 95% CI: 1.78-8.17, P < .001), and recurrent disease (HR: 4.57, 95% CI: 1.97-10.6, P < .001) remained as independent predictors of increased risk of VTE. CONCLUSION Our results suggest that NAFLD may be associated with decreased VTE risk in women with endometrial cancer.

Abstract
Anesthesia for liver transplantation pertains to a continuum of critical care of patients with end-stage liver disease. Hence, anesthesiologists, armed with a comprehensive understanding of pathophysiology and physiologic effects of liver transplantation on recipients, are expected to maintain homeostasis of all organ function. Specifically, patients with fulminant hepatic failure develop significant changes in cerebral function, and cerebral perfusion is maintained by monitoring cerebral blood flow and cerebral metabolic rate of oxygen, and intracranial pressure. Hyperdynamic circulation is challenged by the postreperfusion syndrome, which may lead to cardiovascular collapse. The goal of circulatory support is to maintain tissue perfusion via optimal preload, contractility, and heart rate using the guidance of right-heart catheterization and transesophageal echocardiography. Portopulmonary hypertension and hepatopulmonary syndrome have high morbidity and mortality, and they should be properly evaluated preoperatively. Major bleeding is a common occurrence, and euvolemia is maintained using a rapid infusion device. Pre-existing coagulopathy is compounded by dilution, fibrinolysis, heparin effect, and excessive activation. It is treated using selective component or pharmacologic therapy based on the viscoelastic properties of whole blood. Hypocalcemia and hyperkalemia from massive transfusion, lack of hepatic function, and the postreperfusion syndrome should be aggressively treated. Close communication between all parties involved in liver transplantation is also equally valuable in achieving a successful outcome.

Abstract
An elevated preoperative aspartate aminotransferase (AST) to platelet ratio index (APRI) is reported to be a prognostic factor for patients with hepatocellular carcinoma (HCC) after treatment. However, delta APRI (ΔAPRI), which represents the change from preoperative to postoperative APRI, has received little attention. The present study was designed to evaluate the prognostic value of ΔAPRI in patients with small HCC after liver resection.A retrospective cohort study analyzing 244 patients with small HCC who had undergone liver resection was conducted. Medical data were retrieved from our prospectively maintained database. Patients were divided into 2 groups according to ΔAPRI as follows: group A (ΔAPRI ≥0.02) and group B (ΔAPRI <0.02). The association of demographic and clinical data, overall survival (OS), and recurrence-free survival (RFS) were statistically compared in the 2 groups, and a multivariate analysis was used to identify prognostic factors.The 1, 3, and 5-year OS of patients in group A were 94.2%, 79.5%, and 62.3%, respectively, and 95.1%, 87.9%, and 84.6%, respectively, for patients in group B (P = 0.001). The corresponding 1, 3, and 5-year RFS was 69.0%, 44.7 %, and 28.1%, and 77.4%, 57.0%, and 54.2% for patients in the 2 groups, respectively (P = 0.009). The results of a multivariate analysis indicated that ΔAPRI was an independent prognostic factor for both OS (P = 0.001, hazard ratio 3.115, 95% confidence interval 1.642-5.912) and RFS (P = 0.006, hazard ratio 1.689, 95% confidence interval 1.163-2.452).A positive ΔAPRI after liver resection predicts decreased OS and RFS in patients with small HCC.

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 AND AIM Vibration Controlled Transient Elastography (VCTE) is a non-invasive test for liver fibrosis and cirrhosis but may be inaccurate in some patients, especially in those with chronic hepatitis B. This study aims at improving the accuracy of VCTE in cirrhosis detection by combining ultrasound and routine blood parameters. METHODS Hepatitis B patients with liver biopsies samples ≥20mm underwent VCTE, ultrasound and blood tests, and were divided into training set (n=170) and validation set (n=75). RESULTS An algorithm consisting of VCTE, international normalization ratio (INR), ultrasonic hepatic vessel and platelet count (CIR-4) and a VCTE-based cirrhosis six-index score (CIR-6) comprised VCTE, INR, platelet, albumin, ultrasonic hepatic vessel and liver parenchyma were derived. In training set, area under receiver operating characteristics curve of CIR-6 and CIR-4 to detect cirrhosis was 0.946 and 0.945, respectively, which was superior to that of VCTE 0.907. CIR-4 could save more liver biopsies. In validation set, CIR-6 detected cirrhosis with accuracy similar to that in training set. However, the sensitivity of CIR-4 and VCTE in validation set lowered to 0.538 and 0.846, respectively. CONCLUSIONS Combining routine markers improve the accuracy of VCTE for cirrhosis detection in hepatitis B patients. CIR-6 may be more valuable.

Abstract
Thrombocytopenia is the most common hematological abnormality encountered in patients with chronic liver disease (CLD). In addition to being an indicator of advanced disease and poor prognosis, it frequently prevents crucial interventions. Historically, thrombocytopenia has been attributed to hypersplenism, which is the increased pooling of platelets in a spleen enlarged by congestive splenomegaly secondary to portal hypertension. Over the past decade, however, there have been significant advances in the understanding of thrombopoiesis, which, in turn, has led to an improved understanding of thrombocytopenia in cirrhosis. Multiple factors contribute to the development of thrombocytopenia and these can broadly be divided into those that cause decreased production, splenic sequestration, and increased destruction. Depressed thrombopoietin levels in CLD, together with direct bone marrow suppression, result in a reduced rate of platelet production. Thrombopoietin regulates both platelet production and maturation and is impaired in CLD. Bone marrow suppression can be caused by viruses, alcohol, iron overload, and medications. Splenic sequestration results from hypersplenism. The increased rate of platelet destruction in cirrhosis also occurs through a number of pathways: increased shear stress, increased fibrinolysis, bacterial translocation, and infection result in an increased rate of platelet aggregation, while autoimmune disease and raised titers of antiplatelet immunoglobulin result in the immunologic destruction of platelets. An in-depth understanding of the complex pathophysiology of the thrombocytopenia of CLD is crucial when considering treatment strategies. This review outlines the recent advances in our understanding of thrombocytopenia in cirrhosis and CLD.

Abstract
Long-term graft fibrosis occurs in the majority of pediatric liver transplant recipients. Serial biopsies to monitor graft health are impractical and invasive. The APRI has been evaluated in pediatric liver disease, but not in the context of post-transplantation fibrosis. We aimed to investigate the validity of APRI as a predictor of long-term graft fibrosis in pediatric liver transplant recipients. This was a retrospective, observational study of a cohort of children who underwent liver transplantation at King's College Hospital between 1989 and 2003, with a relevant dataset available. Protocol liver biopsies were performed at 10-yr follow-up and fibrosis was graded using the Ishak scoring system, with S3-6 denoting "significant fibrosis." APRI was calculated concurrently with biopsy. A total of 39 asymptomatic patients (20 males; median age at transplant, 1.43 yr) underwent protocol liver biopsies at a median of 10.39 yr post-transplantation. APRI was associated with significant fibrosis (p = 0.012). AUROC for APRI as a predictor of significant fibrosis was 0.74 (p = 0.013). The optimal cutoff APRI value for significant fibrosis was 0.45 (sensitivity = 0.67; specificity = 0.79; PPV = 0.67; NPV = 0.79). APRI appears to be a useful non-invasive adjunct in the assessment of significant graft fibrosis in the long-term follow-up of pediatric liver transplant survivors.

Abstract
Aspartate aminotransferase to platelet ratio index (APRI) has originally been considered as a noninvasive marker for detecting hepatic fibrosis in patients with chronic hepatitis B and C. APRI has been used for predicting liver-related mortality in patients with chronic hepatitis C virus infection or alcoholic liver disease. However, whether APRI could be useful for predicting mortality in chronic hepatitis B virus (HBV) infection remains unevaluated. This study aims to address this knowledge gap. A total of 193 hospitalized chronic HBV-infected patients (cirrhosis, n = 100; noncirrhosis, n = 93) and 88 healthy subjects were retrospectively enrolled. All patients were followed up for 4 months. Mortality that occurred within 90 days of hospital stay was compared among patients with different APRI. APRI predictive value was evaluated by univariate and multivariate regression embedded in a Cox proportional hazards model. APRI varied significantly in our cohort (range, 0.16-10.00). Elevated APRI was associated with increased severity of liver disease and 3-month mortality in hospitalized patients with HBV-related cirrhosis. Multivariate analysis demonstrated that APRI (odds ratio: 1.456, P < 0.001) and the model for end-stage liver disease score (odds ratio: 1.194, P < 0.001) were 2 independent markers for predicting mortality. APRI is a simple marker that may serve as an additional predictor of 3-month mortality in hospitalized patients with HBV-related decompensated cirrhosis.

Abstract
BACKGROUND & AIMS Different mechanisms including portal hypertension and hypersplenism have been involved in the development of thrombocytopenia in cirrhosis. However, the relative contribution of each one is unknown. The aim was to evaluate simultaneously different mechanisms that determine platelet count in cirrhosis. METHODS Cross-sectional study including cirrhotics (n = 120) with hepatic venous pressure gradient (HVPG) measurement. Samples were obtained from peripheral (P) veins to evaluate thrombopoietin (TPO), stem cell factor, hepatocyte growth factor (HGF), tumour necrosis factor, interleukin-(IL6) and (IL11) and from hepatic (H) veins to evaluate TPO. A subgroup (n = 72) had spleen volume estimation. H and P-TPO were also measured in non-cirrhotic patients (n = 15). RESULTS Patients (Child A: 55, B: 43, C: 22) had a median platelet count of 81 000/mm(3) (IQR 60 500, 110 750), which correlated with spleen volume (r = -0.38, P < 0.001). Platelets were associated also to HVPG (r = -0.47, P = 0.004) and P-TPO (r = 0.31, P = 0.050) only in compensated patients. H-TPO decreased, and the proportion of patients with P-TPO > H-TPO increased, with the presence and the severity of liver disease. H-TPO was correlated with liver function (bilirubin r = -0.350, P < 0.001 and international normalized ratio r = -0.227, P = 0.011). Patients with H-TPO < P-TPO had higher levels of IL-11 and HGF. CONCLUSION Platelet count in cirrhosis is associated mainly to spleen volume, although portal hypertension as estimated by HVPG and liver function plays a significant role in compensated patients. H-TPO and the proportion of patients with P-TPO > H-TPO were associated to the presence and severity of liver disease.

Abstract
Aim To compare the performance of several simple, noninvasive models comprising various serum markers in diagnosing significant liver fibrosis in the same sample of patients with chronic hepatitis B (CHB) with the same judgment standard. Methods A total of 308 patients with CHB who had undergone liver biopsy, laboratory tests, and liver stiffness measurement (LSM) at the Southwest Hospital, Chongqing, China between March 2010 and April 2014 were retrospectively studied. Receiver operating characteristic (ROC) curves and area under ROC curves (AUROCs) were used to analyze the results of the models, which incorporated age-platelet (PLT) index (API model), aspartate transaminase (AST) to alanine aminotransferase (ALT) ratio (AAR model), AST to PLT ratio index (APRI model), γ-glutamyl transpeptidase (GGT) to PLT ratio index (GPRI model), GGT-PLT-albumin index (S index model), age-AST-PLT-ALT index (FIB-4 model), and age-AST-PLT-ALT-international normalized ratio index (Fibro-Q model). Results The AUROCs of the S index, GPRI, FIB-4, APRI, API, Fibro-Q, AAR, and LSM for predicting significant liver fibrosis were 0.726 (P < 0.001), 0.726 (P < 0.001), 0.621 (P = 0.001), 0.619 (P = 0.001), 0.580 (P = 0.033), 0.569 (P = 0.066), 0.495 (P = 0.886), and 0.757 (P < 0.001), respectively. The S index and GPRI had the highest correlation with histopathological scores (r = 0.373, P < 0.001; r = 0.372, P < 0.001, respectively) and LSM values (r = 0.516, P < 0.001; r = 0.513, P < 0.001, respectively). When LSM was combined with S index and GPRI, the AUROCs were 0.753 (P < 0.001) and 0.746 (P < 0.001), respectively. Conclusion S index and GPRI had the best diagnostic performance for significant liver fibrosis and were robust predictors of significant liver fibrosis in patients with CHB for whom transient elastography was unavailable.

Abstract
This clinical study was designed to evaluate the presence of hematocytopenia in patients with splenomegaly caused by non-alcoholic cirrhotic portal hypertension. For this purpose, we randomly selected 358 patients with splenomegaly caused by non-alcoholic cirrhotic portal hypertension and admitted to the clinical data in our hospital between January 1991 and June 2009. Among these 358 patients, 322 patients (90.0 %) showed hematocytopenia, including multi-hemocyte decrease in 206 patients (i.e., 89 patients with a decrease in white blood cell count (WBC) + red blood cell count (RBC) + platelets count (PLT)); 52 patients with WBC + PLT decrease; 29 patients with RBC + PLT decrease; and 36 patients with WBC + RBC decrease) and single-hemocyte decrease in 116 patients (i.e., 31 cases with single PLT decrease; 29 cases with single WBC decrease; and 56 patients with single RBC decrease). After splenectomy, 36 patients (10.0 %) with hematocytopenia presented a statistical improvement of blood cell to normal level (P < 0.05), while 32 patients did not have any change as compared to pre-operative one (P > 0.05). It has to be noted that 4 patients did not received any surgery. Hematocytopenia was not detected in all the patients with splenomegaly caused by cirrhotic portal hypertension, thus it is probably a complication of splenomegaly but not an inevitable manifestation. It was concluded that splenectomy could be an effective treatment for splenomegaly associated with hematocytopenia, but patients without hematocytopenia could choose a non-surgical alternative treatment.

Abstract
Hepatitis C virus (HCV) infection can cause permanent liver damage and
hepatocellular carcinoma, and deaths related to HCV deaths have recently
increased. Chronic HCV infection is often undiagnosed such that the virus
remains infective and transmissible. Identifying HCV infection early is essential
for limiting its spread, but distinguishing individuals who require further HCV
tests is very challenging. Besides identifying high-risk populations, an optimal
subset of indices for routine examination is needed to identify HCV screening
candidates. Therefore, this study analyzed data from 312 randomly chosen blood
donors, including 144 anti-HCV-positive donors and 168 anti-HCV-negative donors. The HCV viral load in each sample was measured by real-time
polymerase chain reaction method. Receiver operating characteristic curves
were used to find the optimal cell blood counts and thrombopoietin
measurements for screening purposes. Correlations with values for key indices
and viral load were also determined. Strong predictors of HCV infection were
found by using receiver operating characteristics curves to analyze the optimal

Abstract
BACKGROUND/AIM To date, liver biopsy has been the gold standard used for the assessment of liver fibrosis in patients with chronic hepatitis C. Our aim was to evaluate the diagnostic performance of a panel of simple blood markers of liver fibrosis and the development a novel score to replace liver biopsy. PATIENTS AND METHODS Liver biochemical profile including transaminases, bilirubin, alkaline phosphatase, and albumin, in addition to platelet count, was evaluated using standard methods in 305 chronic hepatitis C patients. Serum type IV collagen and laminin were assayed using the ELISA technique. Liver biopsies were performed. Statistical analyses were carried out by logistic regression and receiver operating characteristic curves to assess and compare the diagnostic accuracy of blood markers. A stepwise combination algorithm was developed and validated in 317 additional patients. RESULTS The Fibrosis Discriminant Score (FDS) was developed combining collagen, laminin, aspartate aminotransferase/platelet ratio index, and albumin. FDS produced an area under receiver operating characteristic curve of 0.831 for significant fibrosis, 0.791 for advanced fibrosis, and 0.881 for cirrhosis. The FDS was correctly classified in 82% of patients with significant fibrosis with 79% sensitivity and 88% specificity at cut-off 0.66 or more. Similar results were obtained in a validation study in which, of 317 patients, liver biopsy could have been avoided in 81%. CONCLUSION A simple fibrosis index can be useful to select hepatitis C virus-infected patients with a very low risk of significant fibrosis in whom the protocol of liver biopsies may be avoided.

Abstract
Background and Aims Thrombopoietin (TPO) has been implicated in the process of liver regeneration and was found to correlate with hepatic function in patients with liver disease. With this investigation we aimed to determine if perioperative TPO levels were associated with postoperative outcome in patients undergoing liver resection. Methods Perioperative TPO was analyzed prior to liver resection as well as on the first and fifth postoperative day in 46 colorectal cancer patients with liver metastasis (mCRC) as well as 23 hepatocellular carcinoma patients (HCC). Serum markers of liver function within the first postoperative week were used to define liver dysfunction. Results While circulating TPO levels significantly increased one day after liver resection in patients without liver cirrhosis (mCRC) (P < 0.001), patients with underlying liver disease (HCC) failed to significantly induce TPO postoperatively. Accordingly, HCC patients had significantly lower TPO levels on POD1 and 5. Similarly, patients with major resections failed to increase circulating TPO levels. Perioperative dynamics of TPO were found to specifically predict liver dysfunction (AUC: 0.893, P < 0.001) after hepatectomy and remained an independent predictor upon multivariate analysis. Conclusions We here demonstrate that perioperative TPO dynamics are associated with postoperative LD. Postoperative TPO levels were found to be lowest in high-risk patients (HCC patients undergoing major resection) but showed an independent predictive value. Thus, a dampened TPO increase after liver resection reflects a poor capacity for hepatic recovery and may help to identify patients who require close monitoring or intervention for potential complications.

Abstract
Thrombocytopenia (defined as a platelet count <150×10(9)) is a well-known complication in patients with liver cirrhosis and has been observed in 76% to 85% of patients. Significant thrombocytopenia (platelet count <50×10(9) to 75×10(9)) occurs in approximately 13% of patients with cirrhosis. Thrombocytopenia can negatively impact the care of patients with severe liver disease by potentially interfering with diagnostic and therapeutic procedures. Multiple factors can contribute to the development of thrombocytopenia including splenic platelet sequestration, immunological processes, bone marrow suppression by chronic viral infection, and reduced levels or activity of the hematopoietic growth factor thrombopoietin. The present review focuses on the etiologies and management options for severe thrombocytopenia in the setting of advanced liver disease.

Abstract
BACKGROUND Hepatic venous pressure gradient (HVPG) is a prognostic marker in cirrhosis, but is invasive. There is a need to validate a noninvasive marker to measure portal hypertension. Aspartate aminotransferase/platelet ratio index (APRI) is proposed as a good noninvasive estimator of hepatic fibrosis. Whether APRI could be used as noninvasive tool to measure portal hypertension has not been studied. AIM To correlate APRI with HVPG in patients with cirrhosis and to determine the diagnostic usefulness of the APRI in detection of high portal pressure. METHODS APRI and HVPG were measured in consecutive patients of cirrhosis aged 18-75 years, with serum bilirubin <5 mg/dl, Child-Turcotte-Pugh (CTP) score ≤12, and without evidence of acute-on-chronic liver failure or flare. RESULTS This study included 74 patients (median age 47 years, range 20-70 years; 57 males, (77%). The aetiology of cirrhosis was: viral 33 (45%), alcohol 10 (14%), and cryptogenic and others 31 (42%). The median HVPG was 16 mmHg (range 2-28 mmHg). The median APRI was 1.19 (range 0.17-7.92). There was significant correlation between HVPG and APRI (Spearman's rho 0.365; p = 0.001). The ROC curve to study the performance of APRI for predicting high portal pressure (HVPG >12 mmHg) had area under curve 0.716 (95% CI 0.574-0.858). An APRI of ≥1.09 had a sensitivity 66%, specificity 73%, positive predictive value 85%, negative predictive value 47%, and diagnostic accuracy 68% for predicting HVPG >12 mmHg. CONCLUSIONS APRI correlates fairly with HVPG in patients of cirrhosis. An APRI score of ≥1.09 seems to have an acceptable accuracy for prediction of high portal pressure. APRI is a fair, bedside, cost-effective parameter for diagnosis of high portal pressure in patients with cirrhosis.

Abstract
BACKGROUND The benefits of proton beam craniospinal irradiation (PrBCSI) in children have been extensively reported in dosimetric studies. However, there is limited clinical evidence supporting the use of PrBCSI. We compared the acute toxicity of PrBCSI relative to that of conventional photon beam CSI (PhBCSI) in children with brain tumours. MATERIAL AND METHODS We prospectively evaluated the haematological and gastrointestinal toxicities in 30 patients who underwent PrBCSI between April 2008 and December 2012. As a reference group, we retrospectively evaluated the medical records of 13 patients who underwent PhBCSI between April 2003 and April 2012. The median follow-up time from starting CSI was 22 months (range 2-118 months). The mean irradiation dose was 32.1 Gy (range 23.4-39.6 Gy) and 29.4 CGE (cobalt grey equivalents; range 19.8-39.6), in the PrBCSI and PhBCSI groups, respectively (p = 0.236). RESULTS There was no craniospinal fluid space relapse after curative therapy in either group of patients. Thrombocytopenia was less severe in the PrBCSI group than in the PhBCSI group (p = 0.012). The recovery rates of leukocyte and platelet counts measured one month after treatment were significantly greater in the PrBCSI group than in the PhBCSI group (p = 0.003 and p = 0.010, respectively). Diarrhoea was reported by 23% of patients in the PhBCSI group versus none in the PrBCSI group (p = 0.023). CONCLUSIONS The incidence rates of thrombocytopenia and diarrhoea were lower in the PrBCSI group than in the PhBCSI group. One month after completing treatment, the recovery from leukopenia and thrombocytopenia was better in patients treated with PrBCSI than in those treated with PhBCSI.

Abstract
Thrombocytopenia is a major risk factor for cirrhotic liver disease. Patients with thrombocytopenia may have esophageal or gastric varices secondary to portal hypertension, leading to variceal bleeding which exposes the liver to further damage. Here, we present a female pediatric patient with PSC and CD, whose progressive thrombocytopenia was successfully controlled by romiplostim, a TPO receptor agonist. The patient developed bloody diarrhea at four yr of age, and was subsequently diagnosed with PSC and CD when seven yr old. While CD was well-controlled by immunomodulators, the patient's thrombocytopenia gradually progressed resulting in petechiae (platelet count of 11 × 10(9) /L) when she was 10 yr and four months old. She responded poorly to immunoglobulin and corticosteroids. Weekly subcutaneous injection of romiplostim was therefore initiated, and platelet counts were maintained over at 50 × 10(9) /L. She was able to undergo successful LDLT without platelet transfusion seven months after the initiation of romiplostim. Romiplostim was not required after LDLT with improved platelet counts. This case report suggests that romiplostim may be effective in the treatment of thrombocytopenic children with liver cirrhosis and portal hypertension, and in eliminating the need for platelet transfusion during the peri-transplant period.

Abstract
Many noninvasive serum markers have been studied to determine the liver fibrosis score (LFS). In this study, we aimed to investigate the association between thrombopoietin (TPO) levels and the stage of liver fibrosis in patients with chronic hepatitis B (CHB). Seventy-seven patients (64 active and 13 inactive) with CHB were included in this cross-sectional study. Patients were divided into three groups: In group 1, patients with mild or no fibrosis (F0, F1); in group 2, patients with significant fibrosis (F2-F4); and in group 3, inactive CHB carriers. Digital patient records were used to access pre-treatment laboratory findings including HBV DNA, HBeAg, ALT, AST, total bilirubin, PLT, albumin, INR. Liver biopsies were examined by experienced pathologists in our hospital who were blinded to the data of the patients. Serum TPO levels were measured using commercial ELISA kit. Serum TPO levels were significantly lower in patients with active CHB compared with the inactive carriers (528 vs 687.1 p=0.003). There was no statistically significant difference in TPO levels between the patients with and patients without significant fibrosis (568.9 vs 459.8 p=0.367). Correlation analysis with respect to ALT, AST, TPO, HBV-DNA level, platelet count, histological activity index (HAI) and liver fibrosis score was performed. TPO was only weakly positively correlated with AST, ALT and HBV-DNA levels (r=0.269 p=0.018; r=0.341 p=0.002; r=0.308 p=0.006; respectively) and no correlation in TPO with LFS and HAI was found (r=0.140 p=0.270, r=0.162 p=0.201; respectively). TPO was not associated with significant fibrosis (p=0.270). In conclusion, TPO levels were decreased in active CHB patients compared with inactive carriers but there was no correlation between TPO levels and the stage of fibrosis in active CHB.

Abstract
BACKGROUND Patients with cirrhosis usually have thrombocytopenia in discrete levels. The mechanism of thrombocytopenia is thought as splenic sequestration and destruction of platelets, impaired bone marrow generation and diminished hepatic thrombopoietin synthesis. OBJECTIVES The aim of this study was to evaluate serum thrombopoietin levels and its relationship with thrombocytopenia at patients with cirrhosis. PATIENTS AND METHODS Ninety-two cirrhotic patients and 45 healthy controls without history or findings of pathologies that can effect thrombopoietin levels were enrolled by simple random sampling to patient and control groups of this case control study performed at Eskisehir-Turkey. Thrombopoietin was measured in serum samples with a solid phase enzyme-linked immune absorbent assay. Additionally, spleen size and volume index were determined. RESULTS Platelet counts were lower in patients with cirrhosis (97000 ± 8000/mm(3)) than in healthy subjects (240000 ± 51000/mm(3), P < 0.001). Significant difference was determined for platelet counts among child A, B and C stages (Child A vs. Child B P < 0.05 Child A vs. Child C P < 0.001-Child B vs. Child C P < 0.05). Serum TPO concentration was higher (69 ± 12 pg/mL) in cirrhotic group than healthy controls (49 ± 9 pg/ml) (P < 0.05). No significant difference in TPO levels were found among the Child A, B and C stages (64 ± 11 pg/mL, 75 ± 13 pg/mL and 68 ± 10 pg/mL, respectively). Spleen size and SVI was significantly higher in the cirrhotic patients than healthy controls (148 ± 14 mm vs. 98 ± 11 mm, P < 0.001-9167 ± 287 cm(2) vs. 4118 ± 123 cm(2)). Significant difference was determined for spleen size and spleen index among child A, B and C stages (Child A vs. Child B P < 0.05 Child A vs. Child C P < 0.001-Child B vs. Child C P < 0.05). TPO levels were significantly different between cirrhotic patients with platelet levels below 50.000/mm(3) (n = 16, plt-count: 41000 ± 8300/mm(3), TPO levels: 73 ± 7 pg/mL) and above 50.000/mm(3) (n = 76, plt-count: 105000 ± 9500/mm(3), TPO levels: 65 ± 10 pg/mL) (P < 0.01). In correlation analysis, there was a strong negative correlation between platelet count-spleen size (P < 0.001, r = -0.74) and platelet count-serum TPO levels (P < 0.001, r = -0.71). CONCLUSIONS Our results suggest that liver cirrhosis does not cause impaired thrombopoietin production even in the late stage of disease. Thrombopoietin has no contribution for the occurrence of thrombocytopenia in cirrhosis; splenic sequestration seems to be the main factor.

Abstract
AIM To provide a simple fibrosis index combining the routine laboratory markers for predicting significant fibrosis (SF) and cirrhosis in patients with chronic HCV. METHODS Platelet count, ALT, AST, AST to ALT Ratio, AST to Platelet Ratio Index (APRI), Forns index, FIB-4 and Age Platelet Index of 202 liver biopsy performed HCV-infected patients were reviewed. METAVIR classification was used to determine the stage of liver fibrosis. The predictive fibrosis index was constructed by multiple linear regression analysis (- 2.948 + 0.562 × Forns index + 0.288 × APRI + 0.006 × platelet count [10(9)/L]). RESULTS Median (25th-75th interquartile range) age was 52 (42-59) years, and 61% were male. 65.8% (n = 133) had SF (F2-F4) and 23.3% (n = 47) had cirrhosis (F4). For discrimination of SF, AUROCs were: Fibrosis index = 0.869, Forns index = 0.837, APRI = 0.814, platelet count = 0.764. For cirrhosis, AUROCs were: Fibrosis index = 0.911, Forns index = 0.883, APRI = 0.847, platelet count = 0.827. A cut-off point of ≤ 1.2 for fibrosis index excluded SF in 89% of patients with sensitivity of 96%, while > 2.0 predicted SF in 88% of patients with specificity of 86%. Threshold of ≤ 1.9 excluded cirrhosis in 95% of patients with sensitivity of 94%, while > 2.7 showed cirrhosis in 88% of patients with specificity of 95%. In multivariate logistic regression analysis, OR (95% CI) of fibrosis index was 7.825 (3.682-16.629) for SF (p < 0.001) and was 8.672 (4.179-17.996) for cirrhosis (p < 0.001). CONCLUSION SF and cirrhosis were predicted with accuracy of 82% and 89% and were excluded with accuracy of 74% and 82% using this fibrosis index which may potentially decrease the need for liver biopsy in 76% and 83% of patients, respectively.

Abstract
Assessment of liver fibrosis in chronic hepatitis C virus (HCV) infection is considered a relevant part of patient care and key for decision making. Although liver biopsy has been considered the gold standard for staging liver fibrosis, it is an invasive technique and subject to sampling errors and significant intra- and inter-observer variability. Over the last decade, several noninvasive markers were proposed for liver fibrosis diagnosis in chronic HCV infection, with variable performance. Besides the clear advantage of being noninvasive, a more objective interpretation of test results may overcome the mentioned intra- and inter-observer variability of liver biopsy. In addition, these tests can theoretically offer a more accurate view of fibrogenic events occurring in the entire liver with the advantage of providing frequent fibrosis evaluation without additional risk. However, in general, these tests show low accuracy in discriminating between intermediate stages of fibrosis and may be influenced by several hepatic and extra-hepatic conditions. These methods are either serum markers (usually combined in a mathematical model) or imaging modalities that can be used separately or combined in algorithms to improve accuracy. In this review we will discuss the different noninvasive methods that are currently available for the evaluation of liver fibrosis in chronic hepatitis C, their advantages, limitations and application in clinical practice.

Abstract
OBJECTIVE To explore peripheral blood cell variations in hepatic cirrhosis portal hypertension patients with hypersplenism. METHODS Clinical data of 322 hypersplenism patients with decreased peripheral blood cells, admitted with cirrhotic portal hypertension, was retrospectively studied over the last 17 years. RESULTS In 64% (206/322) of patients, more than 2 kinds of blood cell were decreased, including 89 cases of pancytopenia (43.2%), 52 cases of WBC + PLT decrease (25.2%), 29 cases of RBC + PLT decrease (14.1%), and 36 cases of WBC + RBC decrease (17.5%); in 36% (116/322) of patients, single type blood cell decrease occurred, including 31 cases of PLT decrease (26.7%), 29 cases of WBC decrease (25%) and 56 cases of RBC decrease (48.3%). Of 227 routine bone marrow examinations, bone marrow hyperplasia was observed in 118 cases (52.0%), the remainder showed no hyperplasia. For the distinct scope and extent of peripheralblood cell decreases, preoperative blood component transfusions were carried out, then treated by surgery, after whole group splenectomy, the peripheral blood cell count was significantly higher (P<0.05). CONCLUSIONS Of portal hypertensive patients with splenomegaly and hypersplenism, 64% have simultaneous decrease in various blood cells, 36% have decrease in single type blood cells, 52% of patients have bone marrow hyperplasia. A splenectomy can significantly increase the reduction of peripheral blood cells.
