Synthetic extracellular volume fraction without hematocrit sampling for hepatic applications. Abdom Radiol (NY) 2021; 46:4637-4646. [PMID: 34109447 PMCID: PMC8435519 DOI: 10.1007/s00261-021-03140-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 05/03/2021] [Accepted: 05/22/2021] [Indexed: 02/06/2023]
Abstract
Purpose Calculation of extracellular volume fraction (ECV) currently receives increasing interest as a potential biomarker for non-invasive assessment of liver fibrosis. ECV calculation requires hematocrit (Hct) sampling, which might be difficult to obtain in a high-throughput radiology department. The aim of this study was to generate synthetic ECV for hepatic applications without the need for Hct sampling. Methods In this prospective study participants underwent liver MRI. T1 mapping was performed before and after contrast administration. Blood Hct was obtained prior to MRI. We hypothesized that the relationship between Hct and longitudinal relaxation rate of blood (R1 = 1/T1blood) could be calibrated and used to generate the equation for synthetic Htc and ECV calculation. Conventional and synthetic ECV were calculated. Pearson correlation, linear regression and Bland–Altman method were used for statistical analysis. Results 180 consecutive patients were divided into derivation (n = 90) and validation (n = 90) cohorts. In the derivation cohort, native R1blood and Hct showed a linear relationship (HctMOLLI = 98.04 × (1/T1blood) − 33.17, R2 = 0.75, P < 0.001), which was used to calculate synthetic ECV in the validation and whole study cohorts. Synthetic and conventional ECV showed significant correlations in the derivation, validation and in the whole study cohorts (r = 0.99, 0.97 and 0.99, respectively, P < 0.001, respectively) with minimal bias according to the Bland–Altman analysis. Conclusion Synthetic ECV seems to offer an alternative method for non-invasive quantification of the hepatic ECV. It may potentially overcome an important barrier to clinical implementation of ECV and thus, enable broader use of hepatic ECV in routine clinical practice.

Non-invasive assessment of liver fibrosis in autoimmune hepatitis: Diagnostic value of liver magnetic resonance parametric mapping including extracellular volume fraction. Abdom Radiol (NY) 2021; 46:2458-2466. [PMID: 33078245 PMCID: PMC8205876 DOI: 10.1007/s00261-020-02822-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 10/07/2020] [Accepted: 10/10/2020] [Indexed: 12/24/2022]
Abstract
Purpose Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease that leads to severe fibrosis and cirrhosis. The aim of this study was to determine the diagnostic value of T1 and T2 mapping as well as extracellular volume fraction (ECV) for non-invasive assessment of liver fibrosis in AIH patients. Methods In this prospective study, 27 patients (age range: 19–77 years) with AIH underwent liver MRI. T1 and T2 relaxation times as well as ECV were quantified by mapping techniques. The presence of significant fibrosis (≥ F2) was defined as magnetic resonance elastography (MRE)-based liver stiffness ≥ 3.66 kPa. MRE was used as reference standard, against which the diagnostic performance of MRI-derived mapping parameters was tested. Diagnostic performance was compared by utilizing receiver-operating characteristic (ROC) analysis. Results MRE-based liver stiffness correlated with both, hepatic native T1 (r = 0.69; P < 0.001) as well as ECV (r = 0.80; P < 0.001). For the assessment of significant fibrosis, ECV yielded a sensitivity of 85.7% (95% confidence interval (CI): 60.1–96.0%) and a specificity of 84.6% (CI 60.1–96.0%); hepatic native T1 yielded a sensitivity of 85.7% (CI 60.1–96.0%); and a specificity of 76.9% (CI 49.7–91.8%). Diagnostic performance of hepatic ECV (area under the curve (AUC): 0.885), native hepatic T1 (AUC: 0.846) for assessment of significant fibrosis was similar compared to clinical fibrosis scores (APRI (AUC: 0.852), FIB-4 (AUC: 0.758), and AAR (0.654) (P > 0.05 for each comparison)). Conclusion Quantitative mapping parameters such as T1 and ECV can identify significant fibrosis in AIH patients. Future studies are needed to explore the value of parametric mapping for the evaluation of different disease stages.

Abstract
Background Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease, characterized by bile duct inflammation and destruction, leading to biliary fibrosis and cirrhosis. The purpose of this study was to investigate the utility of T1 and T2 mapping parameters, including extracellular volume fraction (ECV) for non-invasive assessment of fibrosis severity in patients with PSC. Methods In this prospective study, patients with PSC diagnosis were consecutively enrolled from January 2019 to July 2020 and underwent liver MRI. Besides morphological sequences, MR elastography (MRE), and T1 and T2 mapping were performed. ECV was calculated from T1 relaxation times. The presence of significant fibrosis (≥ F2) was defined as MRE-derived liver stiffness ≥ 3.66 kPa and used as the reference standard, against which the diagnostic performance of MRI mapping parameters was tested. Student t test, ROC analysis and Pearson correlation were used for statistical analysis. Results 32 patients with PSC (age range 19–77 years) were analyzed. Both, hepatic native T1 (r = 0.66; P < 0.001) and ECV (r = 0.69; P < 0.001) correlated with MRE-derived liver stiffness. To diagnose significant fibrosis (≥ F2), ECV revealed a sensitivity of 84.2% (95% confidence interval (CI) 62.4–94.5%) and a specificity of 84.6% (CI 57.8–95.7%); hepatic native T1 revealed a sensitivity of 52.6% (CI 31.7–72.7%) and a specificity of 100.0% (CI 77.2–100.0%). Hepatic ECV (area under the curve (AUC) 0.858) and native T1 (AUC 0.711) had an equal or higher diagnostic performance for the assessment of significant fibrosis compared to serologic fibrosis scores (APRI (AUC 0.787), FIB-4 (AUC 0.588), AAR (0.570)). Conclusions Hepatic T1 and ECV can diagnose significant fibrosis in patients with PSC. Quantitative mapping has the potential to be a new non-invasive biomarker for liver fibrosis assessment and quantification in PSC patients.

Increased Frequency of Dysfunctional Siglec-7 -CD57 +PD-1 + Natural Killer Cells in Patients With Non-alcoholic Fatty Liver Disease. Front Immunol 2021; 12:603133. [PMID: 33692781 PMCID: PMC7938755 DOI: 10.3389/fimmu.2021.603133] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Accepted: 01/25/2021] [Indexed: 12/16/2022] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) is a progressive disorder that can develop into liver fibrosis and hepatocellular carcinoma. Natural killer (NK) cells have been shown to protect against liver fibrosis and tumorigenesis, suggesting that they may also play a role in the pathogenesis of NAFLD. Sialic acid-binding immunoglobulin-like lectins (Siglecs) are a family of inhibitory and activating receptors expressed by many cell types, including NK cells. Here, we investigated the phenotypic profiles of peripheral blood and intrahepatic NK cells, including expression of Siglecs and immune checkpoint molecules, and their association with NK cell function in patients with NAFLD. Immune cells in the peripheral blood of 42 patients with biopsy-proven NAFLD and 13 healthy volunteers (HVs) were identified by mass cytometry. The function of various NK cell subpopulations was assessed by flow cytometric detection of intracellular IFN-γ and CD107a/LAMP-1, a degranulation marker, after in vitro stimulation. We found that peripheral blood from NAFLD patients, regardless of fibrosis stage, contained significantly fewer total CD56+ NK cell and CD56dim NK cell populations compared with HVs, and the CD56dim cells from NAFLD patients were functionally impaired. Among the Siglecs examined, NK cells predominantly expressed Siglec-7 and Siglec-9, and both the expression levels of Siglec-7 and Siglec-9 on NK cells and the frequencies of Siglec-7+CD56dim NK cells were reduced in NAFLD patients. Notably, Siglec-7 levels on CD56dim NK cells were inversely correlated with PD-1, CD57, and ILT2 levels and positively correlated with NKp30 and NKp46 levels. Further subtyping of NK cells identified a highly dysfunctional Siglec-7-CD57+PD-1+CD56dim NK cell subset that was increased in patients with NAFLD, even those with mild liver fibrosis. Intrahepatic NK cells from NAFLD patients expressed elevated levels of NKG2D and CD69, suggesting a more activated phenotype than normal liver NK cells. These data identify a close association between NK cell function and expression of Siglec-7, CD57, and PD-1 that could potentially be therapeutically targeted in NAFLD.

Diabetes Metab Res Rev 2020; 36:e3294. [PMID: 32017389 DOI: 10.1002/dmrr.3294] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2019] [Revised: 12/15/2019] [Accepted: 01/22/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND Kidney dysfunction is linked to nonalcoholic fatty liver disease (NAFLD) progression including fibrosis, steatosis, or inflammation. We aimed to explore whether lower levels of estimated glomerular filtration rate (eGFR) was associated with increased probability of liver fibrosis. METHODS Two thousand six hundred eighty-nine subjects enrolled from Shanghai, China, were included in this study. NAFLD fibrosis score (NFS) was used to risk stratify NAFLD patients for fibrosis. eGFR was used to assess kidney function. The association of eGFR level with elevated NFS, and thus high risk of fibrosis, was analysed by linear regression and multinomial logistic regression. The predictive power of eGFR was evaluated via receiver operating characteristic (ROC) curve. RESULTS A negative association was found between eGFR and NFS (B = -0.21, 95% CI, -0.37 to -0.04, P = .016). As eGFR quartiles decreased, the prevalence of probable fibrosis increased after adjusting for age, sex, current smoking, waist circumference, duration of diabetes, HbA1c , hypertension, dyslipidaemia, and homeostasis model assessment index of insulin resistance (HOMA-IR) (Q4: reference; Q3: 1.49, 95% CI, 0.82-2.71; Q2: 1.88, 95% CI, 0.97-3.67; Q1: 2.70, 95% CI, 1.36-5.37, Pfor trend = .002, 1SD increment: 0.73, 95% CI, 0.58-0.92). The eGFR level can be an effective indicator in differentiating patients with probable presence of fibrosis from those without (AUROC: 0.71, cut-off point: 92.78 mL/min/1.73 m2 , P < .001). CONCLUSIONS Lower levels of eGFR were associated with higher NFS and thus greater risk of presence of fibrosis in patients with NAFLD and T2DM. Individuals with NAFLD and diabetes should carefully monitor eGFR and receive regular urinalysis, especially when advanced fibrosis is suspected.

Abstract
BACKGROUND AND STUDY AIMS The risk of hepatocarcinogenesis depends on background liver factors, of which fibrosis is a major determinant. Serum markers and scores are of increasing importance in non-invasive diagnosis of hepatic fibrosis. Our aim was to predict the occurrence of hepatocellular carcinoma (HCC) using a non-invasive fibrosis score calculated using routine patient data. PATIENTS AND MTHODS Our retrospective study included 1,291 hepatitis C related-HCC Egyptian patients (Group 1) recruited from the multidisciplinary HCC clinic, Faculty of Medicine, Cairo University in the period between February 2009 and June 2016 and 1072 chronic hepatitis C-naïve patients (Group 2) with advanced fibrosis (≥F3) and cirrhosis (F4). King score, Fibro Q score, Aspartate aminotransferase-to-platelet ratio index (APRI), AST to ALT ratio (AAR), LOK score, Göteborg University Cirrhosis Index (GUCI), Fibro-α and Biotechnology Research Center (BRC) scores were calculated for all patients. Regression analysis and receiver operating characteristics (ROC) were used to calculate the sensitivity, specificity and predictive values for significant scores with the best cut-off for predicting HCC. A regression equation was used to calculate predicted probabilities of HCC using the following variables; age, gender, haemoglobin, international normalised ratio (INR), albumin and alpha fetoprotein. The appropriate score cut-off points yielding optimal sensitivity and specificity were determined by ROC curve analysis. RESULTS There was a highly significant difference between the two groups for all calculated scores (P = 0.0001). Our new score, the Hepatocellular Carcinoma Multidisciplinary Clinic-Cairo University (HMC-CU) score (Logit probability of HCC = - 2.524 + 0.152*age - 0.121*Hb - 0.696*INR - 1.059*Alb + 0.022*AFP + 0.976*Sex. Male = 1, Female = 0), with a cut-off of 0.559 was superior to other scores for predicting HCC, having a sensitivity of 90% and specificity of 80.6%. CONCLUSION The HMC-CU score is a promising, easily calculated, accurate, cost-effective score for HCC prediction in chronic HCV patients with advanced liver fibrosis.

Serum WFA + -M2BP levels for evaluation of early stages of liver fibrosis in patients with chronic hepatitis B virus infection. Liver Int 2017; 37:35-44. [PMID: 27300763 DOI: 10.1111/liv.13188] [Citation(s) in RCA: 54] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Accepted: 06/06/2016] [Indexed: 12/12/2022]
Abstract
BACKGROUND & AIMS Accurate evaluation of liver fibrosis is crucial for predicting progression of chronic hepatitis B virus (HBV) infection. We assessed the utility of a novel fibrosis glycobiomarker Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA+ -M2BP) for evaluating liver fibrosis and disease progression in patients with chronic HBV infection. METHODS We enrolled 774 patients with chronic HBV infection, with or without fibrosis, diagnosed by liver biopsy/FibroScan. Patients who underwent liver biopsy (n = 297) were divided into training (n = 221) and validation (n = 76) groups. Serum WFA+ -M2BP values were measured and compared with FIB-4 index, aspartate aminotransferase (AST)-to-platelet ratio (APRI) and AST-to-alanine aminotransferase ratio (AAR) using receiver-operating characteristic (ROC) analysis. RESULTS Serum WFA+ -M2BP levels increased significantly with fibrosis progression (P < 0.0001). Area under the ROC curve of WFA+ -M2BP for diagnosing significant fibrosis was higher than that of FIB-4 (P = 0.198), APRI (P = 0.017) and AAR (P < 0.001), with sensitivity and specificity in the training set of 60.5% and 79.8% and validation set of 59.5% and 82.1%, respectively. Serum WFA+ -M2BP levels were significantly correlated with FibroScan values (P < 0.0001) and improved the accuracy of FibroScan in assessing significant fibrosis. Changes in WFA+ -M2BP levels were parallel with those in FibroScan values during nucleot(s)ide analogues therapy in patients with chronic HBV infection. CONCLUSIONS WFA+ -M2BP is an accurate serum indicator for assessing early stages of liver fibrosis and may monitor regression of fibrosis during the treatment of chronic HBV infection. WFA+ -M2BP provides a simple and reliable alternative or complementary method to liver biopsy and FibroScan.

BACKGROUND The (13)C-methacetin-breath test and also several noninvasive blood tests comprising routine laboratory parameters have been proposed to predict fibrosis and cirrhosis in chronic hepatitis C. The aim of the study was to compare the diagnostic accuracy between these tests referring to hepatic histology as gold standard. METHODS 96 patients with chronic hepatitis C virus infection underwent percutaneous liver biopsy and the (13)C-methacetin-breath test. The Fibroindex, the aspartate aminotransferase to platelet ratio index , and the aspartate aminotransferase to alanine aminotransferase ratio were used as parameters for the staging of fibrosis. The main endpoint was the area under the characteristic curves for the diagnosis of advanced fibrosis (F3-F4) and cirrhosis (F4) according to the Batts Ludwig criteria. RESULTS ROC analysis revealed a cut-off <14.6 per thousand best with 92.6% sensitivity and 84.1% specificity for the (13)C-methacetin-breath test, for the Fibroindex >1.82 70.4% sensitivity and 91.3% specificity, for the aspartate aminotransferase to platelet ratio >1.0 a 66.7% sensitivity and 75.4% specificity, and for the aspartate aminotransferase to alanine aminotransferase ratio >1.0 63.0% sensitivity and 59.4% specificity in predicting liver cirrhosis. The areas under the curve for the breath test, the Fibroindex, aspartate aminotransferase to platelet ratio and the aspartate aminotransferase to alanine aminotransferase ratio were 0.958, 0.845, 0.799, and 0.688, respectively, when predicting cirrhosis. For identifying patients with advanced fibrosis, the areas under the curve were 0.827, 0.804, 0.779, and 0.561, respectively. Discordances between Fibroindex (21%), aspartate aminotransferase to platelet ratio (29%) or aspartate aminotransferase to alanine aminotransferase ratio (37.6%) and liver biopsy were significantly more frequent than between (13)C-breath test (11.6%) and liver biopsy (P<0.05). CONCLUSION The (13)C-methacetin-breath test is more reliable in predicting advanced fibrosis and cirrhosis than simple biochemical parameters (aspartate aminotransferase to platelet ratio; aspartate aminotransferase to alanine aminotransferase ratio).

Abstract
OBJECTIVES The AST/ALT ratio has shown good diagnostic accuracy in patients with chronic viral liver disease. However, its prognostic utility has never been tested. Recently, the Model for End-Stage Liver Disease (MELD) has been proposed as a simple and effective tool to predict survival in patients with liver cirrhosis. The aims of this study were to assess the 3-month and 1-yr prognostic ability of the AST/ALT ratio in a series of patients with virus-related liver cirrhosis, and to evaluate the relationship between the AST/ALT ratio and the MELD score and to compare their prognostic ability. METHODS The AST/ALT ratios and MELD scores of 99 patients with liver cirrhosis of viral etiology (73 patients with hepatitis C virus and 26 with hepatitis B virus) who had been followed-up for at least 1 yr were retrospectively calculated and correlated with the patients' 3-month and 1-yr prognosis. Receiver operating characteristic curves were used to determine the AST/ALT ratio and the MELD score cut-offs with the best sensitivity (SS) and specificity (SP) in discriminating between patients who survived and those who died. Univariate survival curves were estimated by the Kaplan-Meier method using the cut-offs identified by means of receiver operating characteristic curves. RESULTS AST/ALT ratios and MELD scores showed a significant correlation (r(s) = 0.503, p = 0.0001). In all, 8% and 30% of the patients had died after 3 months and 1 yr of follow-up, respectively. AST/ALT ratios and MELD scores were significantly higher among the patients who died during both 3-month and 1-yr follow-up. An AST/ALT ratio cut-off of 1.17 had 87% SS and 52% SP, whereas a MELD cut-off of 9 had 57% SS and 74% SP in discriminating between patients who survived and those who died after I yr. The combined assessment of the AST/ALT ratio and/or MELD score had 90% SS and 78% SP. Survival curves of the patients showed that both parameters clearly discriminated between patients who survived and those who died in the short term (AST/ALT ratio, p = 0.0094; MELD score, p = 0.0089) as well as in the long term (AST/ALT ratio, p < 0.0005; MELD score, p = 0.004). CONCLUSIONS In patients with virus-related cirrhosis, the AST/ALT ratio has prognostic capability that is not significantly different from that of an established prognostic score such as MELD. Combined assessment of the two parameters increases the medium-term prognostic accuracy.
