Noninvasive Assessment of Liver Fibrosis By Transient Elastography and FIB4/APRI for Prediction of Treatment Response in Chronic Hepatitis C-An Experience from a Tertiary Care Hospital

Enhancing outcome prediction in patients with colorectal liver metastases undergoing hepatectomy: the synergistic impact of FIB-4 index and tumor burden score across KRAS profiles

BACKGROUND

The prognostic value of Fibrosis-4 (FIB-4) index, concerning KRAS status (wild-type [wtKRAS] vs. mutated [mutKRAS]) remains unclear in post-hepatectomy colorectal liver metastases (CRLM). We evaluated the combined impact of FIB-4 and Tumor Burden Score (TBS) on overall survival (OS)/recurrence-free survival (RFS), stratified by KRAS status.

METHODS

CRLM patients undergoing hepatectomy (2000-2020) were analyzed, grouped by TBS/FIB-4.

RESULTS

Among 828 patients, 196 had high FIB-4. High TBS had worse 5-year OS (P < 0.001). In wtKRAS, high TBS correlated with worse OS (P < 0.001), but not in mutKRAS. High FIB-4 correlated with worse OS (P = 0.01). Sub-stratification showed no OS difference by FIB-4 in wtKRAS, but a difference in mutKRAS (P = 0.03). Multivariable analysis identified mutKRAS (HR: 1.90), high TBS (HR: 1.62), and FIB-4 (HR: 1.15) as mortality risk factors. The TBS-FIB-4-KRAS index had highest predictive accuracy. For RFS, TBS and FIB-4 independently stratified outcomes. High TBS was associated with worse RFS in wtKRAS (P < 0.001) but not in mutKRAS. High FIB-4 decreased RFS in mutKRAS (P = 0.001) but not in wtKRAS. FIB-4 was associated with a 10% increased recurrence risk.

CONCLUSION

TBS and FIB-4, alongside KRAS status, should be considered to improve outcome predictions.

Improving Recurrence Prediction in Intrahepatic Cholangiocarcinoma: The Synergistic Impact of the FIB-4 Index and Tumor Burden Score on Post-hepatectomy Outcomes

BACKGROUND

The prognostic role of the fibrosis-4 (FIB-4) index relative to intrahepatic cholangiocarcinoma (ICC) after hepatectomy remains unclear. This study sought to characterize the impact of the FIB-4 index and tumor burden score (TBS) on recurrence and overall survival (OS).

METHODS

ICC patients undergoing hepatectomy (2000-2020) were identified using a multi-institutional database. Patients were categorized as low (low TBS/low FIB-4 index), intermediate (low TBS/high FIB-4 index or high TBS/low FIB-4 index), and high (high TBS/high FIB-4 index).

RESULTS

Among 1168 patients in different TBS and FIB-4 index cohorts, 3-year recurrence varied considerably. For instance, among the patients with low TBS, individuals with a high FIB-4 index had a greater risk of recurrence than patients with a low FIB-4 index (59.9 vs. 47.7%; P = 0.01). Among patients with a high TBS, individuals with a high versus a low FIB-4 index had a higher incidence of recurrence (76.8 vs. 69.0%; P = 0.04). A similar pattern was observed among patients with both a low FIB-4 index (low [47.7%] vs. high [69.0%] TBS) and a high FIB-4 index (low [59.9%] vs. high [76.8%] TBS; both P < 0.001). Patients with a high [27.5%] versus a low [48.8%] TBS; P < 0.001) and patients with a high [34.2%] versus a low [43.5%] FIB-4 index; P = 0.01) had a worse OS. The multivariable analysis demonstrated an increasing risk of recurrence in the intermediate-index (hazard ratio [HR], 1.61; 95% confidence interval [CI], 1.20-2.16; P = 0.001) and high-index (HR, 2.13; 95% CI 1.45-3.13; P < 0.001) groups versus the low-index group.

CONCLUSIONS

Both tumor-related and non-tumorous characteristics should be used to predict risk of recurrence and survival more accurately among patients with ICC following hepatic resection.

Ensemble for evaluating diagnostic efficacy of non-invasive indices in predicting liver fibrosis in untreated hepatitis C virus population

BACKGROUND

Hepatitis C virus (HCV) infection progresses through various phases, starting with inflammation and ending with hepatocellular carcinoma. There are several invasive and non-invasive methods to diagnose chronic HCV infection. The invasive methods have their benefits but are linked to morbidity and complications. Thus, it is important to analyze the potential of non-invasive methods as an alternative. Shear wave elastography (SWE) is a non-invasive imaging tool widely validated in clinical and research studies as a surrogate marker of liver fibrosis. Liver fibrosis determination by invasive liver biopsy and non-invasive SWE agree closely in clinical studies and therefore both are gold standards.

AIM

To analyzed the diagnostic efficacy of non-invasive indices [serum fibronectin, aspartate aminotransferase to platelet ratio index (APRI), alanine aminotransferase ratio (AAR), and fibrosis-4 (FIB-4)] in relation to SWE. We have used an Artificial Intelligence method to predict the severity of liver fibrosis and uncover the complex relationship between non-invasive indices and fibrosis severity.

METHODS

We have conducted a hospital-based study considering 100 untreated patients detected as HCV positive using a quantitative Real-Time Polymerase Chain Reaction assay. We performed statistical and probabilistic analyses to determine the relationship between non-invasive indices and the severity of fibrosis. We also used standard diagnostic methods to measure the diagnostic accuracy for all the subjects.

RESULTS

The results of our study showed that fibronectin is a highly accurate diagnostic tool for predicting fibrosis stages (mild, moderate, and severe). This was based on its sensitivity (100%, 92.2%, 96.2%), specificity (96%, 100%, 98.6%), Youden's index (0.960, 0.922, 0.948), area under receiver operating characteristic curve (0.999, 0.993, 0.922), and Likelihood test (LR+ > 10 and LR- < 0.1). Additionally, our Bayesian Network analysis revealed that fibronectin (> 200), AAR (> 1), APRI (> 3), and FIB-4 (> 4) were all strongly associated with patients who had severe fibrosis, with a 100% probability.

CONCLUSION

We have found a strong correlation between fibronectin and liver fibrosis progression in HCV patients. Additionally, we observed that the severity of liver fibrosis increases with an increase in the non-invasive indices that we investigated.

Clinical study of standard residual liver volume and transient elastography in predicting poor prognosis of patients after hemihepatectomy

BACKGROUND

Liver cancer resection, especially in patients with hemihepatectomy or extended hemihepatectomy, often leads to poor prognosis, such as liver insufficiency and even liver failure and death, because the standard residual liver volume (SRLV) cannot be fully compensated after surgery.

AIM

To explore the risk factors of poor prognosis after hemihepatectomy for hepatocellular carcinoma and evaluate the application value of related prognostic approaches.

METHODS

The clinical data of 35 patients with primary liver cancer in Nantong Third People's Hospital from February 2016 to July 2020 were retrospectively analyzed. The receiver operating characteristic curve was created using medcac19.0.4 to compare the critical values of the SRLV in different stages of liver fibrosis after hemihepatectomy with those of liver dysfunction after hemihepatectomy. It was constructed by combining the Child-Pugh score to evaluate its application value in predicting liver function compensation.

RESULTS

The liver stiffness measure (LSM) value and SRLV were associated with liver dysfunction after hemihepatectomy. Logistic regression analysis showed that an LSM value ≥ 25 kPa [odds ratio (OR) = 6.254, P < 0.05] and SRLV ≤ 0.290 L/m2 (OR = 5.686, P < 0.05) were independent risk factors for postoperative liver dysfunction. The accuracy of the new liver reserve evaluation model for predicting postoperative liver function was higher than that of the Child-Pugh score (P < 0.05).

CONCLUSION

SRLV and LSM values can be used to evaluate the safety of hemihepatectomy. The new liver reserve evaluation model has good application potential in the evaluation of liver reserve function after hemihepatectomy.

RDW Predicts Fibrosis in Patients with Chronic Hepatitis B Having Persistently Normal ALT Levels

Background

There are studies on the determination of hepatic fibrosis with noninvasive markers but data about liver biopsy results and noninvasive markers in patients with chronic hepatitis B (CHB) are limited. The aim of this study is to determine the relationship between pathological findings and noninvasive markers, and to determine the marker that predicts fibrosis in patients with consistently normal serum alanine aminotransferase (ALT) levels, diagnosed with CHB and undergoing liver biopsy.

Methods

A total of 122 patients with CHB, 29 of them with HbeAg (+), aged 30 years and older, HBV DNA > 2000 IU / ml, and serum ALT levels measured four times in the last year, were consistently normal, and 93 of them with HbeAg (-) were included in the study. Demographic characteristics of patients, laboratory parameters, histological activity index (HAI) and fibrosis values obtained in liver biopsy, and noninvasive markers (AP (age-platelet) index, APRI (AST/Platelet ratio) and FIB-4 score, neutrophil/lymphocyte ratio, mean platelet volume (MPV) and erythrocyte distribution width (RDW) were recorded.

Results

The relationship between RDW value and fibrosis was statistically significant in the HbeAg (+) group (p<0.001). The relationship between AP index, APRI and FIB-4 score, neutrophil/lymphocyte ratio and MPV with fibrosis was not statistically significant (>0.05 for each).

Conclusion

It has been shown that the RDW value can be used to predict fibrosis in CHB patients with normal ALT and HbeAg (+), and the cut-off value for RDW is 12.

Diagnostic performance of non-invasive liver fibrosis risk scores in biopsy-proven non-alcoholic fatty liver disease patients in India

BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. India and other developing countries are witnessing an unprecedented rise in the prevalence of NAFLD. As part of population-level strategy, at primary healthcare, an efficient risk stratification is crucial to ensure appropriate and timely referral of individuals who require care at secondary and tertiary levels. The present study was conducted to assess the diagnostic performance of two non-invasive risk scores, fibrosis-4 (FIB-4), and NAFLD fibrosis score (NFS), in Indian patients of biopsy-proven NAFLD.

METHODS

We conducted a retrospective analysis of biopsy-proven NAFLD patients that reported to our center between 2009 and 2015. Clinical and laboratory data were collected and two non-invasive fibrosis scores, NFS and FIB-4 score, were calculated using the original formulas. Liver biopsy was utilized as gold standard for diagnosis of NAFLD, diagnostic performance was determined by plotting receiver operator characteristic (ROC) curves and area under the ROC curve (AUROC) was calculated for each score.

RESULTS

The mean age of 272 patients included was 40 (11.85) years and 187 (79.24%) were men. We found that the AUROCs for FIB-4 score (0.634) was higher for any degree of fibrosis as compared to NFS (0.566). The AUROC for FIB-4 for advanced liver fibrosis was 0.640 (.550-.730). The performance of the scores for advanced liver fibrosis was comparable with overlapping confidence intervals for both scores.

CONCLUSION

The present study found an average performance of FIB-4 and NFS risk scores for detecting advanced liver fibrosis in Indian population. This study highlights the need for devising novel context-specific risk scores for efficient risk stratification of NAFLD patients in India.

Long-term hepatic and cardiac health in patients diagnosed with Sheehan's syndrome

PURPOSE

Sheehan's syndrome (SS) is characterised by chronic pituitary insufficiency following a vascular insult to the pituitary in the peripartum period. There is a lack of substantial evidence on the long-term hepatic and cardiac consequences in these patients, following hormone replacement.

METHODS

Patients with a diagnosis of SS were recruited for the study. Detailed clinico-biochemical and radiological evaluation were performed in all patients (n = 60). Hepatic and cardiac complications were assessed using fibroscan and echocardiography (2D speckle-tracking) respectively, in a subset of patients (n = 29) as well as age-and BMI-matched controls (n = 26). Controlled attenuation parameter (for steatosis) and liver stiffness measurement (for fibrosis) were used to define non-alcoholic fatty liver disease (NAFLD). Diastolic cardiac function was evaluated using standard criteria and systolic function by ejection fraction and global longitudinal strain (GLS).

RESULTS

The mean age of the cohort was 42.7 ± 11.6 years. Multiple (≥ 2) hormone deficiencies were present in 68.8% of patients, with hypothyroidism (91.4%), hypocortisolism (88.3%), and growth hormone (GH) deficiency (85.7%) being the most common. At a mean follow-up of 9.8 ± 6.8 years, NAFLD was present in 63% of patients, with 51% having severe steatosis, which was predicted by the presence of GH deficiency and higher body mass index. Though the ejection fraction was similar, increased left ventricular GLS (18.8 vs. 7.7%) was present in a significantly higher number of patients versus controls.

CONCLUSION

NAFLD, especially severe hepatic steatosis, is highly prevalent in SS. Subclinical cardiac systolic dysfunction (impaired GLS) is also more common, but of mild intensity.

Serum Matrix Metalloproteinase 7 as a Diagnostic and Prognostic Biomarker for Extrahepatic Biliary Atresia

Background

Differentiation of neonatal cholestasis into neonatal hepatitis (NH) and extrahepatic biliary atresia (EHBA) is essential to formulate the treatment plan; promptness is indispensable for optimal outcomes. The clinical and nonoperative algorithms lack precision; the gold standard investigations (liver biopsy or per-operative cholangiogram) are invasive. There is a need for a noninvasive test which is both, sensitive and specific and has a high likelihood ratio.

Aim

To study the (diagnostic) role of matrix metalloproteinase 7 (MMP-7) as a serum biomarker to differentiate between EHBA and NH and evaluate the prognostic significance in EHBA based on its correlation with liver histopathology and serological predictors of liver fibrosis - Aspartate-to-Platelet Ratio Index (APRI) and Fibrosis-4 (FIB-4).

Materials and Methods

This was a prospective study conducted upon patients of neonatal cholestasis presenting with acholic stools (n = 46) with equal number of controls (n = 45) with no liver pathology. Observational parametric included disease-specific workup and serum MMP-7 levels (all participants); liver biopsyl and APRI-FIB-4 (EHBA).

Results

(Diagnostic) Serum MMP-7 levels were significantly elevated in EHBA (n = 25; 28 ng/mL) as compared to those in NH (n = 21; 1.88 ng/mL) and normal infants (n = 45; 1.2 ng/mL) (P < 0.001 for both). Serum cutoff at 4.99 ng/mL differentiated EHBA-NH with a high sensitivity (96%), specificity (90.5%), and a negative predictive value (95%), with the number needed to misdiagnose being 23. (Prognostic) Inflammatory activity and fibrosis-stage on liver histopathology (METAVIR-and-Ishak scores) correlated with MMP-7 levels. APRI and FIB-4 scores also depicted a strong correlation with each other, age of the patient, and liver fibrosis.

Conclusions

MMP-7 has a diagnostic value in differentiating EHBA from NH and may also be used as a prognostic biomarker in the follow-up of these patients. MMP-7 levels in controls may be used as a baseline for future studies.

Sofosbuvir and Velpatasvir combination is safe and effective in treating chronic hepatitis C in end-stage renal disease on maintenance haemodialysis

BACKGROUND & AIMS

There is emerging data on the use of Sofosbuvir-based directly acting antiviral (DAA) drug regimens in chronic hepatitis C (CHC) patients with end-stage renal disease (ESRD) on maintenance haemodialysis (MHD). We evaluated the safety and efficacy of Sofosbuvir plus Velpatasvir fixed-dose combination in CHC patients with ESRD on MHD.

METHODS

Fifty-one CHC patients with ESRD on MHD were included in a real-life prospective study. All patients irrespective of genotype; presence of cirrhosis; treatment naive or experienced status were treated with full-dose Sofosbuvir (400 mg) plus Velpatasvir (100 mg) fixed-dosed combination given daily for 12 weeks. The efficacy was assessed by the sustained virological response (SVR12) with negative HCV RNA 12 weeks after the end of treatment (ETR). Side effects if any were recorded in all patients.

RESULTS

The median HCV RNA level in 51 CHC patients [Males 41 (80.4%), mean age 42.8 ± 14.6 years] was 2.0 × 10⁶ IU/mL. HCV genotype was available in 19 patients with predominant genotype 1 in 15 (79%) patients. Ten (19.6%) patients had evidence of cirrhosis (defined as LSM ≥ 12.5 kPa on Transient Elastography), and 8 (15.6%) patients were treatment experienced. Testing for ETR was done in 36 patients and all 36 (100%) patients achieved ETR, and 49 patients (96%) achieved SVR 12. All 51 patients tolerated the Sofosbuvir + Velpatasvir combination, with none of the patients reporting any serious adverse event.

CONCLUSION

Sofosbuvir plus Velpatasvir fixed-dose combination is safe and effective in treating CHC in patients with ESRD on MHD.

Fibrosis-4 Index, a Noninvasive Fibrosis Marker, Predicts Survival Outcomes After Hepatectomy for Colorectal Cancer Liver Metastases

BACKGROUND

Liver fibrosis influences liver regeneration and surgical outcomes, and several noninvasive models based on laboratory data have been developed to predict liver fibrosis. This study was performed to determine whether the Fibrosis-4 (FIB-4) index, a noninvasive fibrosis marker, can predict the prognosis in patients with colorectal liver metastases (CRLM) undergoing hepatectomy.

METHODS

This retrospective study involved 193 consecutive patients with CRLM who underwent hepatectomy. The FIB-4 index was calculated by laboratory data and age before hepatectomy and before preoperative chemotherapy. The FIB-4 cut-off was determined using survival classification and regression tree analysis. Patients were divided into two groups (high and low FIB-4 index), and post-hepatectomy overall survival (OS) and recurrence-free survival (RFS) were investigated.

RESULTS

In total, 193 patients were evaluated. Chemotherapy before hepatectomy was performed in 105 (54.4%) patients. A high FIB-4 index (> 2.736) was found in 39 (20.2%) patients. OS was significantly shorter in patients with a high FIB-4 index than those with a low FIB-4 index in the univariate (45.9 vs. 74.4 months, log-rank p = 0.007) and multivariate analysis (hazard ratio 2.28, 95% confidence interval 1.39-3.74; p = 0.001). Among patients who received chemotherapy before hepatectomy, those with a high FIB-4 index had significantly shorter RFS (6.9 vs. 45.3 months, log-rank p = 0.047) and OS (23.9 vs. 55.0 months, log-rank p = 0.003) than those with a low FIB-4 index. This association was also confirmed by multivariate analysis (hazard ratio 4.28, 95% confidence interval 1.46-12.6; p = 0.008).

CONCLUSION

Both the preoperative and prechemotherapy FIB-4 index can predict long-term outcomes after hepatectomy in patients with CRLM.

Different Hepatitis C Virus Infection Statuses Show a Significant Risk of Developing Type 2 Diabetes Mellitus: A Network Meta-Analysis

BACKGROUND

The role of hepatitis C virus (HCV) infection statuses in the development of type 2 diabetes mellitus (T2DM) has not been completely understood.

AIM

To evaluate the prevalence of T2DM in patients with different HCV infection statuses.

METHODS

We conducted a systematic study on T2DM risk in five types of individuals with different HCV infection statuses: non-HCV controls, HCV-cleared patients, chronic HCV patients without cirrhosis, patients with HCV cirrhosis and patients with decompensated HCV cirrhosis. Studies published from 2010 to 2019 were selected. Both pairwise and network meta-analyses were employed to compare the T2DM risk among patients with different HCV infection statuses.

RESULTS

The pairwise meta-analysis showed that non-HCV (OR = 0.60, 95% CI [0.47-0.78]) had a lower risk of T2DM compared with CHC, while cirrhosis had a significant higher risk (OR = 1.90, 95% CI [1.60-2.26]). Network meta-analysis further demonstrated patients with HCV infection were at a significantly higher risk of T2DM than those without HCV infection or with HCV clearance, while decompensated cirrhosis had a significant higher T2DM risk than non-HCV (OR = 3.84, 95% CI [2.01-7.34]), patients with HCV clearance (OR = 3.17, 95% CI [1.49-6.73]), and CHC patients (OR = 2.21, 95% CI [1.24-3.94]).

CONCLUSIONS

HCV infection is a significant risk factor for developing T2DM. CHC, cirrhosis, and decompensated cirrhosis contribute to an increasingly greater risk of T2DM, but HCV clearance spontaneously or through clinical treatment may immediately reduce the risk of the onset and development of T2DM.

[Diagnostic accuracy of predictive indexes of liver fibrosis in patients with chronic hepatitis C]

AIM

Assessment of the diagnostic accuracy of predictive indexes of liver fibrosis for the identification of severe fibrosis and cirrhosis (F3F4) in patients with chronic hepatitis C (CHC).

MATERIALS AND METHODS

The retrospective design study included 127 patients with chronic hepatitis C (mean age 44.511.1 years). To assess the degree of liver fibrosis, all patients underwent transient elastography using a Fibroscan (EchoSens, France) and predictive indexes of liver fibrosis were calculated (APRI, FIB-4, discriminant Bonacini score). Transient elastography was considered as a reference method for assessing the degree of liver fibrosis for subsequent comparison of results with predictive fibrosis indixes.

RESULTS

The sensitivity of the APRI index for the identification of severe fibrosis and cirrhosis of the liver (F3F4) was 79%, and specificity was 69%. The FIB-4 index showed greater specificity (86%), but less sensitivity (68%). The sensitivity of the discriminant Bonacini scale was 81%, and the specificity was 77%. The positive predictive value of the APRI index, FIB-4 and the Bonacini scale for the identification of severe fibrosis and cirrhosis of the liver (F3F4) in patients with chronic hepatitis C was 66; 78 and 72% respectively, and negative predictive value 82; 78 and 84% respectively.

CONCLUSION

The results of this study indicate the relatively high diagnostic accuracy of a number of predictive indexes for evaluating liver fibrosis (APRI, FIB-4, discriminant Bonachini scale) in identifying severe fibrosis and cirrhosis of the liver (F3F4) in patients with chronic hepatitis C.

Low-Dose Sofosbuvir Is Safe and Effective in Treating Chronic Hepatitis C in Patients with Severe Renal Impairment or End-Stage Renal Disease

BACKGROUND AND AIMS

There is sparse data on the use of Sofosbuvir based directly acting antiviral (DAA) drug regimens in chronic hepatitis C (CHC) patients with chronic kidney disease (CKD) with estimated glomerular filtration rate (eGFR) less than 30 mL/min/1.73 m². We evaluated the safety and efficacy of low-dose Sofosbuvir plus full-dose Daclatasvir in CHC patients with CKD.

METHODS

Sixty-five CHC patients with CKD with eGFR less than 30 mL/min/1.73 m² [54 (83%) patients with ESRD on hemodialysis] were included. All patients irrespective of genotype were treated with half-dose Sofosbuvir [200 mg (half tablet of 400 mg)] plus full-dose Daclatasvir (60 mg) given daily for either 12 or 24 weeks given in patients with genotype 3 cirrhosis. The efficacy was assessed by the sustained virological response (SVR12) with negative HCV RNA 12 weeks after the end of treatment (ETR).

RESULTS

The median HCV RNA level in 65 patients (Males 40, mean age 42.9 ± 13 years) was 1.65 × 10⁶ (1.2 × 10³-1.73 × 10⁸) IU/mL with 42 (64.6%) patients having HCV genotype 1, followed by genotype 3 and 2 in 22 (34%) and 1 (1.4%) patients, respectively. Twenty-one (32%) patients had evidence of cirrhosis, and ten (15.4%) patients were treatment experienced. Sixty-four (98.5%) patients achieved ETR, and 65 (100%) patients attained SVR12. All patients tolerated the DAAs well with none of the patients reporting any serious adverse events. Minor side effects noted were nausea seen in five (7.7%) patients, insomnia and headache in four (6.2%) patients each, and pruritus in one (1.5%) patient.

CONCLUSION

Low-dose Sofosbuvir and full-dose Daclatasvir are safe and effective in treating CHC in patients with CKD with eGFR less than 30 mL/min/1.73 m².
