Significant Fibrosis In Patients Research Articles

Prevalence and risk factors of significant fibrosis in chronic hepatitis B patients with concurrent metabolic dysfunction-associated steatotic liver disease

Introduction and objectivesSignificant fibrosis is an indicator of clinical intervention for both chronic hepatitis B (CHB) and metabolic dysfunction-associated steatotic liver disease (MASLD). There remains a paucity of data regarding the clinical impact of biopsy-defined MASLD on significant fibrosis in CHB patients. The current study aims to elucidate whether patients with concomitant MASLD are at higher risk of significant fibrosis in patients with CHB. Patients and methodsThis retrospective research of two tertiary hospitals comprised 1818 patients between 2009 and 2021 with CHB and hepatic steatosis who had not received antiviral therapy. Pathologic findings by liver biopsy were contrasted between CHB group (n = 844) and CHB + MASLD (n = 974) group. METAVIR values of F≥2 were used to categorize significant fibrosis. ResultsPatients with CHB + MASLD had more significant fibrosis (35.5 % vs. 23.5 %, p < 0.001) than CHB group. The presence of MASLD [adjusted odds ratio (aOR) 2.055, 95 % confidence interval (CI) 1.635–2.584; p < 0.001] was strongly associated with significant fibrosis in all CHB patients. There was a trend for patients with more cardiometabolic risk factors (CMRFs) to have a higher prevalence of significant fibrosis: (25.7 % in CMRF1 subgroup v.s. 34.9 % in CMRF2 subgroup v.s. 53.7 % in CMRF≥ 3 subgroup, p < 0.001). Patients with CMRF≥3 had a three-fold higher significant fibrosis than those with just one CMRF. ConclusionsMASLD was associated with higher fibrosis stage in patients with CHB. Early detection and intervention are crucial to patients with three or more cardiometabolic risk factors.

Serum dithiothreitol-oxidizing capacity (DOC) is a promising biomarker for excluding significant liver fibrosis: a proof-of-concept study

BackgroundAPRI and FIB-4 scores are used to exclude clinically significant fibrosis (defined as stage ≥ F2) in patients with chronic viral hepatitis. However, the cut-offs for these scores (generated by Youden indices) vary between different patient cohorts. This study aimed to evaluate whether serum dithiothreitol-oxidizing capacity (DOC), i.e., a surrogate test of quiescin sulfhydryl oxidase-1, which is a matrix remodeling enzyme, could be used to non-invasively identify significant fibrosis in patients with various chronic liver diseases (CLDs).MethodsDiagnostic performance of DOC was compared with APRI and FIB-4 for identifying significant fibrosis. ROC curve analyses were undertaken in: a) two chronic hepatitis B (CHB) cohorts, independently established from hospitals in Wenzhou (n = 208) and Hefei (n = 120); b) a MASLD cohort from Wenzhou hospital (n = 122); and c) a cohort with multiple CLD etiologies (except CHB and MASLD; n = 102), which was identified from patients in both hospitals. Cut-offs were calculated using the Youden index. All CLD patients (n = 552) were then stratified by age for ROC curve analyses and cut-off calculations.ResultsStratified by CLD etiology or age, ROC curve analyses consistently showed that the DOC test was superior to APRI and FIB-4 for discriminating between clinically significant fibrosis and no fibrosis, when APRI and FIB-4 showed poor/modest diagnostic performance (P < 0.05, P < 0.01 and P < 0.001 in 3, 1 and 3 cohort comparisons, respectively). Conversely, the DOC test was equivalent to APRI and FIB-4 when all tests showed moderate/adequate diagnostic performances (P > 0.05 in 11 cohort comparisons). DOC had a significant advantage over APRI or FIB-4 scores for establishing a uniform cut-off independently of age and CLD etiology (coefficients of variation of DOC, APRI and FIB-4 cut-offs were 1.7%, 22.9% and 47.6% in cohorts stratified by CLD etiology, 2.0%, 26.7% and 29.5% in cohorts stratified by age, respectively). The uniform cut-off was 2.13, yielded from all patients examined. Surprisingly, the uniform cut-off was the same as the DOC upper limit of normal with a specificity of 99%, estimated from 275 healthy control individuals. Hence, the uniform cut-off should possess a high negative predictive value for excluding significant fibrosis in primary care settings. A high DOC cut-off with 97.5% specificity could be used for detecting significant fibrosis (≥ F2) with an acceptable positive predictive value (87.1%).ConclusionsThis proof-of-concept study suggests that the DOC test may efficiently rule out and rule in significant liver fibrosis, thereby reducing the numbers of unnecessary liver biopsies. Moreover, the DOC test may be helpful for clinicians to exclude significant liver fibrosis in the general population.

Revisiting the steatosis-associated fibrosis estimator score in young Asian subjects with steatotic liver disease and consideration for population variability.

The steatosis-associated fibrosis estimator (SAFE) score has been developed to distinguish clinically significant fibrosis in patients with steatotic liver disease (SLD). However, validation of its performance in Asian subjects is limited. This study aimed to evaluate the performance of the SAFE score in Asian subjects with biopsy-proven SLD and in different subgroups according to age, sex, and body mass index. We retrospectively analyzed 6383 living liver donors who underwent a liver biopsy between 2005 and 2023. Of these, 1551 subjects with biopsy-proven SLD were included. The performance of the SAFE score was evaluated using areas under the curve and compared with those of the nonalcoholic fatty liver disease fibrosis score (NFS) and fibrosis-4 index (FIB-4). The prevalence of clinically significant fibrosis in the cohort was 2.2%. The proportion of subjects with a "low-risk" SAFE score was the highest (91.0%), followed by those with "intermediate-risk" (7.8%) and "high-risk" (1.2%) scores. The prevalence of fibrosis in subjects with low-risk, intermediate-risk, and high-risk scores was 1.6%, 6.6%, and 21.1%, respectively. The SAFE outperformed FIB-4 and NFS (area under the curve: 0.70 vs 0.64 for both NFS and FIB-4). However, it showed low diagnostic accuracy and sensitivity (27%) at the low cutoff (SAFE<0) in subjects aged 30-39years (fibrosis: 1.2%), despite having a high negative predictive value (0.99). While the SAFE score demonstrates superior performance compared with other noninvasive tests in Asian subjects with SLD, its performance varies across age groups. In younger subjects, particularly, its performance may be more limited.

Non-invasive prediction nomogram for predicting significant fibrosis in patients with metabolic-associated fatty liver disease: a cross-sectional study

Background and Aim This study aims to validate the efficacy of the conventional non-invasive score in predicting significant fibrosis in metabolic-associated fatty liver disease (MAFLD) and to develop a non-invasive prediction model for MAFLD. Methods This cross-sectional study was conducted among 7701 participants with MAFLD from August 2018 to December 2023. All participants were divided into a training cohort and a validation cohort. The study compared different subgroups’ demographic, anthropometric, and laboratory examination indicators and conducted logistic regression analysis to assess the correlation between independent variables and liver fibrosis. Nomograms were created using the logistic regression model. The predictive values of noninvasive models and nomograms were evaluated using receiver operating characteristic (ROC) curve analysis and decision curve analysis (DCA). Results Four nomograms were developed for the quantitative analysis of significant liver fibrosis risk based on the multivariate logistic regression analysis results. The nomogram’s area under ROC curves (AUC) was 0.710, 0.714, 0.748, and 0.715 in overall MAFLD, OW-MAFLD, Lean-MAFLD, and T2DM-MAFLD, respectively. The nomogram had a higher AUC in all MAFLD participants and OW-MAFLD than the other non-invasive scores. The DCA curve showed that the net benefit of each nomogram was higher than that of APRI and FIB-4. In the validation cohort, the AUCs of the nomograms were 0.722, 0.750, 0.719, and 0.705, respectively. Conclusion APRI, FIB-4, and NFS performed poorly predicting significant fibrosis in patients with MAFLD. The new model demonstrated improved diagnostic accuracy and clinical applicability in identifying significant fibrosis in MAFLD.

The Portal Venous Pulsatility Index and Main Portal Vein Diameter as Surrogate Markers for Liver Fibrosis in Nonalcoholic Fatty Liver Disease and Metabolic-Dysfunction-Associated Steatotic Liver Disease.

(1) Background: Despite numerous noninvasive methods for assessing liver fibrosis, effective ultrasound parameters remain limited. We aimed to identify easily measurable ultrasound parameters capable of predicting liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) and metabolic-dysfunction-associated steatotic liver disease (MASLD); (2) Methods: The data of 994 patients diagnosed with NAFLD via ultrasound at the Armed Forces Goyang Hospital were retrospectively collected from June 2022 to July 2023. A liver stiffness measurement (LSM) ≥ 8.2 kPa was classified as significant fibrosis. Liver steatosis with cardiometabolic risk factors was defined as MASLD. Two ultrasound variables, the portal venous pulsatility index (VPI) and main portal vein diameter (MPVD), were measured; (3) Results: Of 994 patients, 68 had significant fibrosis. Significant differences in VPI (0.27 vs. 0.34, p < 0.001) and MPVD (10.16 mm vs. 8.98 mm, p < 0.001) were observed between the fibrotic and non-fibrotic groups. A logistic analysis adjusted for age and body mass index (BMI) revealed that only VPI (OR of 0.955, p = 0.022, VPI on a 0.01 scale) and MPVD (OR of 1.501, p < 0.001) were significantly associated with significant liver fibrosis. In the MASLD cohort (n = 939), VPI and MPVD were associated with significant fibrosis. To achieve better accuracy in predicting liver fibrosis, we established a nomogram that incorporated MPVD and VPI. The established nomogram was validated in the test cohort, yielding an area under the receiver operating characteristic curve of 0.821 for detecting significant liver fibrosis; (4) Conclusions: VPI and MPVD, as possible surrogate markers, are useful in predicting significant fibrosis in patients with NAFLD and MASLD.

A combination of non-invasive tests for the detection of significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease is not superior to magnetic resonance elastography alone.

The aims of the present study were to investigate a combination of magnetic resonance elastography (MRE) and vibration-controlled transient elastography (VCTE) or MRE and fibrosis score 4 (FIB-4) in the detection of significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). Between November 5, 2021, and March 4, 2022, a total of 119 consecutive patients with MASLD were included. Liver stiffness was measured using liver biopsy, MRE, VCTE, and FIB-4. Data were collected from outpatient visit charts. Significant fibrosis was defined as ≥ stage 2 fibrosis. All 119 MASLD patients were Caucasian, and their median age was 55 years. MRE, VCTE, and FIB-4 demonstrated significant accuracy in the detection of significant fibrosis with an area under the ROC curve (AUC) of 0.848 ± 0.036 (p < 0.001), 0.632 ± 0.052 (p = 0.012), and 0.664 ± 0.051 (p = 0.001), respectively. However, the diagnostic performance of MRE was superior compared to that of VCTE (AUC difference: 0.216 ± 0.053, p < 0.001) and FIB-4 (AUC difference: 0.184 ± 0.058, p = 0.001). With logistic regression analysis, it was determined that when compared to MRE alone, a combination of MRE and TE (p = 0.880) or MRE and FIB-4 (p = 0.455) were not superior for detecting significant fibrosis. MRE alone is an accurate and non-invasive method for the identification of MASLD patients with significant fibrosis. Magnetic resonance elastography alone accurately detects significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease. • In routine clinical practice, several non-invasive biochemical-based biomarkers and imaging methods are widely used to assess liver fibrosis in patients with metabolic dysfunction-associated steatotic liver disease. • Magnetic resonance elastography (MRE) is more accuratethanvibration-controlled transient elastography (VCTE) or fibrosis score 4 (FIB-4) for assessing liver fibrosis and identifying significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease. • The combination of MRE andVCTE or MRE and FIB-4 was not superior to MRE alone.

Interleukin-34 is more suitable than macrophage colony-stimulating factor for predicting liver significant fibrosis in patients with chronic hepatitis B

Aims Interleukin-34 (IL-34) and macrophage colony-stimulating factor (CSF-1) have similar functions, such as promoting the formation of liver fibrosis. This study aimed to evaluate and compare the diagnostic value of serum IL-34 and CSF-1 for significant liver fibrosis in patients with chronic hepatitis B (CHB). Methods A total of 369 CHB patients, consisting of 208 HBeAg-negative patients and 161 HBeAg-positive patients, were enrolled in this study. Additionally, 72 healthy individuals served as healthy controls (HCs). Serum levels of IL-34 and CSF-1 were measured using the enzyme-linked immunosorbent assay method. Liver fibrosis grades were assessed using the modified Scheuer scoring system. Results Serum IL-34 and CSF-1 levels exhibited significant elevation in both HBeAg-negative and HBeAg-positive patients in comparison to HCs (p < 0.001). IL-34 emerged as an independent factor linked to significant liver fibrosis, whereas CSF-1 did not exhibit such an association. Receiver operating characteristic (ROC) analysis indicated higher areas under the curves (AUCs) for IL-34 (0.814, p < 0.001 and 0.673, p < 0.001) when diagnosing significant liver fibrosis in HBeAg-negative and HBeAg-positive patients, respectively, as opposed to CSF-1 (0.602, p < 0.001; 0.619, p = 0.385). Within the HBeAg-negative patient subgroup, the AUC for IL-34 surpassed that of FIB-4 (p = 0.009) and APRI (p = 0.045). Conclusion Serum IL-34 has the potential to be a straightforward and practical biomarker that demonstrates superior performance to serum CSF-1 in the diagnosis of significant liver fibrosis in CHB patients, especially within the HBeAg-negative patients.

Development and validation of a non-invasive model for predicting significant fibrosis based on patients with nonalcoholic fatty liver disease in the United States.

Liver fibrosis is closely related to abnormal liver function and liver cancer. Accurate noninvasive assessment of liver fibrosis is of great significance for preventing disease progression and treatment decisions. The purpose of this study was to develop and validate a non-invasive predictive model for the asses`sment of significant fibrosis in patients with non-alcoholic fatty liver disease. Information on all participants for 2017-2018 was extracted from the NHANES database. The eligible patients with significant fibrosis (n=123) and non-significant fibrosis (n=898) were selected to form the original dataset. Variable selection was performed using least absolute shrinkage and selection operator (Lasso) regression, and multivariate logistic regression analysis was used to develop a prediction model. The utility of the model is assessed in terms of its discrimination, calibration and clinical usability. Bootstrap-resampling internal validation was used to measure the accuracy of the prediction model. This study established a new model consisting of 9 common clinical indicators and developed an online calculator to show the model. Compared with the previously proposed liver fibrosis scoring system, this model showed the best discrimination and predictive performance in the training cohort (0.812,95%CI 0.769-0.855) and the validation cohort (0.805,95%CI 0.762-0.847), with the highest area under curve. Specificity(0.823), sensitivity(0.699), positive likelihood ratio(3.949) and negative likelihood ratio(0.366) were equally excellent. The calibration plot of the predicted probability and the actual occurrence probability of significant fibrosis shows excellent consistency, indicating that the model calibration is outstanding. Combined with decision curve analysis, this model has a great benefit in the range of 0.1-0.8 threshold probability, and has a good application value for the diagnosis of clinical significant fibrosis. This study proposes a new non-invasive diagnostic model that combines clinical indicators to provide an accurate and convenient individualized diagnosis of significant fibrosis in patients with non-alcoholic fatty liver disease.

Association of Non-Invasive Markers with Significant Fibrosis in Patients with Nonalcoholic Fatty Liver Disease: A Cross-Sectional Study.

The identification of significant fibrosis is critical for predicting the prognosis of non-alcoholic fatty liver disease (NAFLD). This study aimed to compare the predictive value of chitinase-3-like protein 1 (CHl3L1) and other non-invasive biomarkers, as well as to establish a novel non-invasive diagnostic model for assessing the risk of significant fibrosis in NAFLD. A total of 71 patients with confirmed NAFLD based on liver biopsy were included in this study. Serum CHI3L1 levels and other non-invasive fibrosis assessment measures were determined. The aspartate aminotransferase-to-platelet ratio index (APRI) and Fibrosis-4 Index (FIB-4) were calculated to assess the diagnostic superiority of serum CHI3L1 compared to other non-invasive fibrosis assessment measures. Multivariate logistic regression analysis was conducted to identify relevant variables for constructing a diagnostic model. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic accuracy of each index, including the area under ROC curve (AUC), sensitivity, and specificity. A nomogram was established based on the logistic regression model. Serum CHI3LI levels were found to be higher in NAFLD patients with significant fibrosis compared to those without significant fibrosis. Multivariate logistic regression analysis revealed that aspartate aminotransferase (AST), type IV collagen (IV-C), CHI3L1, and liver stiffness measurement (LSM) were identified as potential independent risk factors associated with significant fibrosis in patients. The AUC of CHI3L1 for diagnosing significant liver fibrosis was 0.716 (0.596,0.836), with the optimal cut-off point of 125.315. The nomogram incorporating CHI3LI, AST, IV-C, and LSM further improved the potential predictive value, with an AUC for diagnosing significant fibrosis of 0.864 (0.766,0.962). This was superior to IV-C, CHI3L1, LSM, and APRI (all p < 0.05). The diagnostic model constructed by CHI3L1 combined with the existing non-invasive markers AST, IV-C, and LSM can help assess the risk of significant liver fibrosis in NAFLD.

The combination of the enhanced liver fibrosis and FIB-4 scores to determine significant fibrosis in patients with nonalcoholic fatty liver disease.

The presence of fibrosis in NAFLD is the most significant risk factor for adverse outcomes. We determined the cutoff scores of two non-invasive te sts (NITs) to rule in and rule out significant fibrosis among NAFLD patients. Clinical data and liver biopsies were used for NAFLD patients included in this analysis (2001-2020). The enhanced liver fibrosis (ELF) and FIB-4 NITs were calculated. Liver biopsies were read by a single hematopathologist and scored by the NASH CRN criteria. Significant fibrosis was defined as stage F2-F4. There were 463 NAFLD patients included: 48 ± 13 years old, 31% male, 35% type 2 diabetes; 39% had significant fibrosis; mean ELF score was 9.0 ± 1.2, mean FIB-4 score was 1.22 ± 1.05. Patients with significant fibrosis were older, more commonly male, had lower BMI but more components of metabolic syndrome, higher ELF and FIB-4 (p < 0.0001). The performance of the two NITs in identifying significant fibrosis was: AUC (95% CI)=0.78 (0.74-0.82) for ELF, 0.79 (0.75-0.83) for FIB-4. The combination of ELF score ≥9.8 and FIB-4 ≥ 1.96 returned a positive predictive value of 95% which can reliably rule in significant fibrosis (sensitivity 22%, specificity >99%), while an ELF score ≤7.7 or FIB-4 ≤ 0.30 had a negative predictive value of 95% ruling out significant fibrosis (sensitivity 98%, specificity 22%). The combination of ELF and FIB-4 may provide practitioners with easily obtained information to risk stratify patients with NAFLD who could be referred to specialists or for enrollment in clinical trials.

Biomarkers for staging fibrosis and non-alcoholic steatohepatitis in non-alcoholic fatty liver disease (the LITMUS project): a comparative diagnostic accuracy study

The reference standard for detecting non-alcoholic steatohepatitis (NASH) and staging fibrosis-liver biopsy-is invasive and resource intensive. Non-invasive biomarkers are urgently needed, but few studies have compared these biomarkers in a single cohort. As part of the Liver Investigation: Testing Marker Utility in Steatohepatitis (LITMUS) project, we aimed to evaluate the diagnostic accuracy of 17 biomarkers and multimarker scores in detecting NASH and clinically significant fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) and identify their optimal cutoffs as screening tests in clinical trial recruitment. This was a comparative diagnostic accuracy study in people with biopsy-confirmed NAFLD from 13 countries across Europe, recruited between Jan 6, 2010, and Dec 29, 2017, from the LITMUS metacohort of the prospective European NAFLD Registry. Adults (aged ≥18 years) with paired liver biopsy and serum samples were eligible; those with excessive alcohol consumption or evidence of other chronic liver diseases were excluded. The diagnostic accuracy of the biomarkers was expressed as the area under the receiver operating characteristic curve (AUC) with liver histology as the reference standard and compared with the Fibrosis-4 index for liver fibrosis (FIB-4) in the same subgroup. Target conditions were the presence of NASH with clinically significant fibrosis (ie, at-risk NASH; NAFLD Activity Score ≥4 and F≥2) or the presence of advanced fibrosis (F≥3), analysed in all participants with complete data. We identified thres holds for each biomarker for reducing the number of biopsy-based screen failures when recruiting people with both NASH and clinically significant fibrosis for future trials. Of 1430 participants with NAFLD in the LITMUS metacohort with serum samples, 966 (403 women and 563 men) were included after all exclusion criteria had been applied. 335 (35%) of 966 participants had biopsy-confirmed NASH and clinically significant fibrosis and 271 (28%) had advanced fibrosis. For people with NASH and clinically significant fibrosis, no single biomarker or multimarker score significantly reached the predefined AUC 0·80 acceptability threshold (AUCs ranging from 0·61 [95% CI 0·54-0·67] for FibroScan controlled attenuation parameter to 0·81 [0·75-0·86] for SomaSignal), with accuracy mostly similar to FIB-4. Regarding detection of advanced fibrosis, SomaSignal (AUC 0·90 [95% CI 0·86-0·94]), ADAPT (0·85 [0·81-0·89]), and FibroScan liver stiffness measurement (0·83 [0·80-0·86]) reached acceptable accuracy. With 11 of 17 markers, histological screen failure rates could be reduced to 33% in trials if only people who were marker positive had a biopsy for evaluating eligibility. The best screening performance for NASH and clinically significant fibrosis was observed for SomaSignal (number needed to test [NNT] to find one true positive was four [95% CI 4-5]), then ADAPT (six [5-7]), MACK-3 (seven [6-8]), and PRO-C3 (nine [7-11]). None of the single markers or multimarker scores achieved the predefined acceptable AUC for replacing biopsy in detecting people with both NASH and clinically significant fibrosis. However, several biomarkers could be applied in a prescreening strategy in clinical trial recruitment. The performance of promising markers will be further evaluated in the ongoing prospective LITMUS study cohort. The Innovative Medicines Initiative 2 Joint Undertaking.

Noninvasive diagnosis of liver fibrosis in schistosomiasis japonica: Opportunities and challenges

Noninvasive diagnosis of liver fibrosis in schistosomiasis japonica: Opportunities and challenges

Clinical usefulness of Mac-2 binding protein glycosylation isomer for diagnosing liver cirrhosis and significant fibrosis in patients with chronic liver disease: A retrospective single-center study.

Accurate diagnosis of liver cirrhosis (LC) and significant fibrosis in patients with chronic liver disease (CLD) is important. The Mac-2 binding protein glycosylation isomer (M2BPGi) has emerged as a novel serum biomarker for liver fibrosis; however, insufficient clinical data of M2BPGi are available in patients with CLD. Therefore, we performed a retrospective cohort study to investigate the clinical usefulness of serum M2BPGi for assessing LC and significant fibrosis in CLD patients. We retrospectively reviewed the CLD patients with measured serum M2BPGi at Kosin University Gospel Hospital between January 2016 and December 2019. Multivariate logistic regression analyses were conducted to identify the independent factors associated with LC. The diagnostic power of serum M2BPGi for LC and significant fibrosis (≥F2) was evaluated and compared to that of other serum biomarkers using receiver operating characteristic curve and area under the curve (AUC). A total of 454 patients enrolled in this study. M2BPGi (adjusted odds ratio [aOR], 1.77; 95% confidence interval [CI], 1.52–2.07) and fibrosis index based on four factors (aOR, 1.23; 95% CI, 1.11–1.37) were identified as significant independent factors for LC. The AUC of M2BPGi for LC (0.866) and significant fibrosis (0.816) were comparable to those of fibrosis index based on four factors (0.860, 0.773), aspartate aminotransferase-to-platelet ratio index (0.806, 0.752), and gamma-glutamyl transpeptidase-to-platelet ratio (0.759, 0.710). The optimal cut-off values for M2BPGi for LC and significant fibrosis were 1.37 and 0.89, respectively. Serum M2BPGi levels were significantly correlated with liver stiffness measurements (ρ = 0.778). Serum M2BPGi is a reliable noninvasive method for the assessment of LC and significant fibrosis in patients with CLD.

Evaluation of Six Noninvasive Methods for the Detection of Fibrosis in Chinese Patients with Obesity and Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the world, and liver fibrosis has been proven to be associated with liver diseaserelated events and total mortality. Several noninvasive methods have been developed, but whether those methods are suitable for the detection of fibrosis in Chinese patients with obesity and NAFLD has not been completely elucidated. This study aimed to compare the efficacy of fibrosis-4 (FIB-4), aspartate transaminase to platelet ratio index (APRI), modified aspartate transaminase to platelet ratio index (m-APRI), BARD (BARD (BMI (body mass index) > 28 = 1 point, AAR (aspartate aminotransferase/alanine aminotransferase) > 0.8 = 2 points, DM (diabetes mellitus) = 1 point)), NAFLD fibrosis score (NFS), and shear wave elastography (SWE) in the evaluation of the degree of liver fibrosis in Chinese patients with obesity and NAFLD. A retrospective study consisted of 100 patients. The accuracy of FIB-4, APRI, m-APRI, BARD, NFS, and SWE in the assessment of significant or advanced liver fibrosis in Chinese patients with obesity and NAFLD was compared. Weight and alanine aminotransferase (ALT) were independent risk factors for liver fibrosis. SWE, APRI, and m-APRI had significant efficiency in the diagnosis of significant fibrosis in patients with obesity and NAFLD. APRI and SWE were superior to the other methods in the diagnosis of significant and advanced liver fibrosis in patients with obesity and NAFLD. APRI and SWE showed no statistically significant difference in diagnostic efficiency. Weight and ALT are independent risk factors for liver fibrosis progression in NAFLD patients. SWE and APRI have predictive value for significant and advanced fibrosis of NAFLD in Chinese patients with obesity.

1105-P: Moderate-to-Advanced Liver Fibrosis Is Common in Patients with Type 1 Diabetes (T1D) and Nonalcoholic Fatty Liver Disease (NAFLD)

ADA guidelines recommend screening for significant fibrosis in patients with type 2 diabetes and steatosis or elevated ALT. In contrast, there are limited or inconsistent data about the prevalence of NAFLD and liver fibrosis in patients with type 1 diabetes (T1D) . We screened patients with T1D unaware of having NAFLD at a tertiary diabetes center and excluded those with secondary causes of fatty liver or heavy alcohol consumption. We utilized liver stiffness measurement (LSM) by transient elastography for fibrosis screening and controlled attenuation parameter (CAP) for steatosis screening. Referral to hepatology unit was done based on a priori criteria suggestive of clinically significant fibrosis (≥F2) . We screened 285 patients with T1D (age 48±16 yrs; 55% females; 93% non-Hispanic whites; BMI 27±4.9 kg/m2; diabetes duration 28±15 yrs; A1c 7.1±1.1%; total insulin dose 48±27 units/day; AST 23±9 IU/L; ALT 20±12 IU/L) . The prevalence of NAFLD (CAP≥274 dB/m) was 29.3% (95%CI 24-35) and fibrosis (LSM≥7 kPa) 11% (95%CI 7-15) . Among those with NAFLD (n=76) , 13% (95%CI 5-20) had ≥F2 fibrosis (LSM ≥ 8.2 kPa) suggesting nonalcoholic steatohepatitis. Among patients with NAFLD and those with fibrosis respectively, 72% and 59% had ALT≤30 IU/L (men) or ≤IU/L (women) . After multivariate adjustment, larger waist circumference (&amp;gt;102 cm [men]; &amp;gt;88 cm [women]) and BMI &amp;gt;30 kg/m2 were associated with increased risk of steatosis (OR 4.13, 95%CI 1.61-10.6, p=0.014; 2.4, 1.3-4.5, p=0.007, respectively) . Continuous glucose monitoring parameters (e.g., %TIR) were not associated with steatosis or fibrosis. In conclusion, NAFLD and liver fibrosis are common in patients with T1D. ALT alone is inadequate for screening. Central obesity, consistent with insulin resistance, independently predicts NAFLD. Future guidelines should consider screening for steatosis and significant fibrosis in patients with T1D and high BMI or large waistline even without elevated ALT. Disclosure S.Tomah: None.

MAFLD is Associated with the Risk of Liver Fibrosis and Inflammatory Activity in HBeAg-Negative CHB Patients.

PurposeChronic hepatitis B (CHB) and metabolic associated fatty liver disease (MAFLD) are both important public health problems. The effect of concomitant MAFLD on patients with CHB is still unclear. This study aimed to explore the influence of MAFLD on liver fibrosis and inflammation in CHB patients with different hepatitis B e antigen (HBeAg) status.Patients and MethodsWe retrospectively collected the clinical data of 399 treatment-naïve CHB patients who underwent liver biopsy. All patients were divided into two groups (HBeAg± group). Logistic regression analysis was used to identify factors associated with liver inflammatory activity and significant fibrosis in patients with CHB. Multivariable logistic regressions were repeated in subgroups stratified by HBeAg status.ResultsIn patients with CHB, MAFLD was independently associated with a risk of moderate-to-severe liver activity and significant fibrosis (P <0.05). In the HBeAg-negative group, patients with MAFLD had significantly higher levels of alanine aminotransferase (ALT) (P <0.05) and more severe liver inflammatory activity and fibrosis (P <0.05) compared to those without MAFLD. MAFLD was independently associated with a risk of moderate-to-severe liver activity (A ≥3: OR 3.97, 95% CI 1.71–9.22, P =0.001) and significant fibrosis (F ≥2: OR 2.02, 95% CI 1.09–3.73, P =0.026). In the HBeAg-positive group, MAFLD was found to be independently associated with moderate-to-severe liver activity (OR 2.44, 95% CI 1.03–5.79, P =0.044) but not fibrosis (P =0.618).ConclusionMAFLD is associated with the risk of liver fibrosis and inflammatory activity in HBeAg-negative CHB patients. Sufficient attention should be paid to the prevention and treatment of MAFLD in patients with CHB, especially in HBeAg-negative patients.

Association Between Neutrophil-to-Lymphocyte Ratio with Inflammatory Activity and Fibrosis in Non-alcoholic Fatty Liver Disease.

Inflammation plays an important role in the development and progression of non-alcoholic steatohepatitis (NASH), and NASH is a powerful driving force for the progression of fibrosis. The neutrophil-to-lymphocyte ratio (NLR) is a simple emerging indicator of inflammation. We aimed to assess the potential association between NLR and histological severity of non-alcoholic fatty liver disease (NAFLD). This retrospective study consisted of 231 patients with biopsy-proven NAFLD in China from August 2017 to September 2019. The steatosis, activity, and fibrosis scoring system were used to evaluate liver biopsy tissue. Of the 231 patients with NAFLD, advanced inflammatory activity was present in 43.3% and significant fibrosis in 25.5% of patients. Multivariate logistic regression analysis showed NLR to be correlated with advanced inflammatory activity (Odds ratio (OR): 0.62, 95% CI: 0.42-0.94, P = .025) and significant fibrosis (OR: 0.57, 95% CI: 0.35-0.94, P = .028). The NLR was inversely associated with the degree of steatosis, lobular inflammation and fibrosis (r = -0.16, P = .014; r = -0.15, P = .019; r = -0.13, P = .046, respectively), but had no association with the severity of ballooning. The multivariate-adjusted models had good predictability for advanced inflammatory activity (area under curves (AUC) 0.790, 95% CI: 0.730-0.850) and for significant fibrosis (AUC 0.798, 95% CI: 0.728-0.868). This study showed negative correlations between elevated NLR levels with advanced inflammatory activity and significant fibrosis in patients with NAFLD. Our results also suggested that NLR could be considered as a simple and noninvasive mark to identify high-risk populations in NAFLD.
