Effect of metabolic dysfunction on the risk of liver-related events in patients cured of hepatitis C virus.

The impact of metabolic dysfunction or metabolic dysfunction-associated fatty liver disease (MAFLD) on liver-related events (LREs) in patients with chronic hepatitis C (CHC) who had achieved a sustained virologic response (SVR) to direct-acting antiviral agents (DAAs) is unknown. A total of 924 patients with cured CHC and documented body mass index (BMI) were included in the analysis, and the data period was from September 2012 to April 2022. Hepatic steatosis was identified either through ultrasonography or blood biomarkers. Metabolic dysfunction was defined as the presence of overweight or obesity (BMI ≥ 23 kg/m2), type 2 diabetes mellitus (DM), and metabolic dysregulation. Patients may have more than one metabolic dysfunction. Variables at 12 or 24 weeks after DAA therapy (PW12) were used to identify predictors of LREs. The median age of the 924 patients was 58 (49-65) years. Of the participants, 418 (45.2%) were male. The median BMI was 24.01 (21.78-26.73) kg/m2, and 174 (18.8%) patients had DM. A multivariable Cox regression analysis revealed that age, male, albumin, total bilirubin, alpha-fetoprotein (AFP), metabolic dysfunction (hazard ratio: 1.709, 95% confidence interval: 1.128-2.591, P = .011), and FIB-4 > 3.25 were independent predictors of LREs. Type 2 DM and metabolic dysregulation exhibited a larger time-dependent area under the receiver operating characteristic curve for LREs than did overweight or obesity. Moreover, metabolic dysfunction was identified to be an independent predictor of hepatocellular carcinoma. Metabolic dysfunction increased the risk of LREs and HCC in patients with CHC who had achieved an SVR to DAA therapy.

Liver stiffness and spleen stiffness predict distinct liver-related events after hepatitis C eradication with direct-acting antivirals.

BACKGROUND: /Purpose: This study aimed to directly compare the utility of liver stiffness (LS) and spleen stiffness (SS) at sustained virologic response (SVR) for predicting hepatocellular carcinoma (HCC) and non-HCC events in patients with chronic hepatitis C (CHC) after direct-acting antiviral therapy. METHODS: This retrospective study included 695 CHC patients who achieved SVR and underwent LS and SS measurements. LS and SS were measured using point shear wave elastography and compared head-to-head. RESULTS: During a median follow-up of 29.5 months, 49 (7.1%) patients developed liver-related events (LREs), including 28 HCC and 22 non-HCC events after SVR. Multivariable Cox regression analysis revealed that age, albumin level, and LS (≥ versus <1.46 m/s) at SVR (adjusted hazard ratio [aHR]: 5.390; 95% confidence interval [CI]: 2.349-12.364; p < 0.001), but not SS at SVR, significantly predicted the overall risk of post-SVR LREs (n = 49). Furthermore, age and LS (≥ versus <1.46 m/s) at SVR (aHR: 6.759; 95% CI: 2.317-19.723; p < 0.001), but not SS at SVR, independently predicted the risk of post-SVR incident HCC. In contrast, SS (≥ versus <2.87 m/s) at SVR (aHR: 11.212; 95% CI: 1.564-20.132; p = 0.021) and albumin level, but not LS at SVR, significantly predicted the risk of post-SVR non-HCC events. CONCLUSION: Post-SVR LS better predicts HCC risk. Post-SVR SS helps predict non-HCC risk after antiviral therapy for CHC. LS and SS at SVR provide complementary prognostic information regarding risks of HCC and non-HCC events in the post-SVR setting. Further validation is warranted in larger cohorts.

Combination treatment of pembrolizumab with DC-CIK cell therapy for advanced hepatocellular carcinoma: A case report.

Background: Recently, immunotherapy has emerged as a promising method for advanced HCC treatment. There are several clinical trials and meta-analyses of immune checkpoint inhibitors and immune cell therapy, but clinical evidence on the combination of these two therapies is lacking. Case description: A 66-year-old man with chronic hepatitis B-related cirrhosis complained of acute abdominal pain in an emergency department of a hospital. On exams, there was a palpable mass in the right upper quadrant of his abdomen. Contrast-enhanced abdominal computed tomography showed a large tumor in the right lobe, 13 cm × 17 cm in size, and right portal vein thrombosis. The alpha-fetoprotein (AFP) level was 30,905 mg/dL. Therefore this patient was diagnosed with BCLC stage C hepatocellular carcinoma (HCC). He underwent trans-arterial chemo-embolization (TACE), abdominal radiotherapy, nivolumab, and lenvatinib. His disease had been under control until two years later, the disease progressed with multiple lung metastases, and his AFP level rose from around 1000 to 17,000 ng/ml. At this stage, he underwent new combination immunotherapy in January 2022. He used pembrolizumab (100 mg) first, and the AFP level decreased by 600 ng/ml daily. Then he received DC-CIK cell therapy two weeks after using pembrolizumab, and the AFP level declined to 900 ng/ml a day. Unfortunately, severe pneumonitis and tension pneumothorax developed after therapy. The patient denied undergoing further treatment and expired peacefully. Conclusion: The previous in-vivo study found that combination immunotherapy can improve tumor control in the mice model. Besides, in previous clinical studies, the level of AFP may be a surrogate marker of tumor response. Therefore we thought the more rapidly declined level of AFP was the clinical evidence of the synergistic effect of checkpoint inhibitors combined with cell therapy in HCC treatment.

Unlocking Colchicine's Untapped Potential: A Paradigm Shift in Hepatocellular Carcinoma Prevention.

Background: Liver cancer and notably hepatocellular carcinoma (HCC), results in significantly high mortality rates worldwide. Chronic hepatitis and fatty liver, recognized precursors, underscore the imperative need for effective preventive strategies. This study explores colchicine, traditionally acknowledged for its anti-inflammatory properties and investigates its potential in liver cancer prevention. Methods: Utilizing the iHi Data Platform of China Medical University Hospital, Taiwan, this study analyzed two decades of medical data, incorporating 10,353 patients each in the Colchicine and Non-Colchicine cohorts, to investigate the association between colchicine use and liver cancer risk. Results: The study identified that colchicine users exhibited a 19% reduction in liver cancer risk, with a multivariable-adjusted odds ratio of 0.81 after accounting for confounding variables. Additionally, the influence of gender and comorbidities like diabetes mellitus on liver cancer risk was identified, corroborating the existing literature. A notable finding was that the prolonged use of colchicine was associated with improved outcomes, indicating a potential dose-response relationship. Conclusions: This study proposes a potential new role for colchicine in liver cancer prevention, extending beyond its established anti-inflammatory applications. While the findings are promising, further research is essential to validate these results. This research may serve as a foundation for future studies, aiming to further explore colchicine's role via clinical trials and in-depth investigations, potentially impacting preventive strategies for liver cancer.

Combined CRAFITY score and α-fetoprotein response predicts treatment outcomes in patients with unresectable hepatocellular carcinoma receiving anti-programmed death-1 blockade-based immunotherapy.

Biomarkers for predicting the treatment efficacy of immune checkpoint inhibitor (ICI)-based therapy in patients with unresectable hepatocellular carcinoma (uHCC) are crucial. Previous studies demonstrated that C-reactive protein and alpha-fetoprotein (AFP) in immunotherapy (CRAFITY) score at baseline predicted treatment outcomes and that patients with uHCC with AFP response, defined as > 15% decline in AFP level within the initial 3 months of ICI-based therapy, had favorable outcomes when receiving ICI-based therapy. However, whether the combination of CRAFITY score and AFP response could be used to predict treatment efficacy of programmed death-1 (PD-1) blockade-based therapy in uHCC patients remains unclear. We retrospectively enrolled 110 consecutive uHCC patients from May 2017 to March 2022. The median ICI treatment duration was 2.85 (1.67-6.63) months, and 87 patients received combination therapies. The objective response and disease control rates were 21.8% and 46.4%, respectively. The duration of progression-free survival (PFS) and overall survival (OS) was 2.87 (2.16-3.58) months and 8.20 (4.23-12.17) months, respectively. We categorized patients into three groups based on CRAFITY score (2 vs 0/1) and AFP response: patients with a CRAFITY score of 0/1 and AFP response (Group 1), those with a CRAFITY score of 2 and no AFP response (group 3), and those who did not belong to Group 1 and 3 (i.e., Group 2). The combination of CRAFITY score and AFP response could predict disease control and could predict PFS compared with CRAFITY score or AFP response alone. The combination of CRAFITY score and AFP response was an independent predictor of OS (Group 2 vs Group 1, HR: 4.513, 95% CI 1.990-10.234; Group 3 vs Group 1, HR: 3.551, 95% CI 1.544-8.168). Our findings indicated that the combination of CRAFITY score and AFP response could predict disease control, PFS, and OS in uHCC patients receiving PD-1 blockade-based immunotherapy.

Special presentation of bronchobiliary fistula after transcatheter arterial chemoembolization: A case report.

RATIONALE: Transcatheter arterial chemoembolization (TACE) is a widely adopted treatment for advanced stage hepatocellular carcinoma (HCC). Nevertheless, several complications may occur, such as hepatic artery injury, nontarget embolization, pulmonary embolism, hepatic abscess, biloma, biliary strictures, and hepatic failure. However, bronchobiliary fistula is rarely mentioned before. PATIENT CONCERNS: A 65-year-old man with HCC underwent the TACE procedure, and then he encountered fever, dyspnea, abdominal pain, and abundant yellowish purulent bronchorrhea. DIAGNOSIS: Bronchobiliary fistula was diagnosed based on the computed tomography (CT) scan of his chest, which revealed the right lower lobe of his lung was connected to a hepatic cystic lesion. INTERVENTIONS: Percutaneous transhepatic cystic drainage was performed, and we obtained yellowish bile, showing the same characteristics as the patient's bronchorrhea. OUTCOMES: We kept drainage of his biloma and provided supportive care as the patient wished. Unfortunately, the patient passed away due to progressive right lower lobe pneumonia 2 weeks later. LESSONS: This case exhibits a typical CT scan image that was helpful for the diagnosis of post-TACE bronchobiliary fistula. Post-TACE bronchobiliary fistula formation hypothesis includes biliary tree injuries with subsequent biloma formation and diaphragmatic injuries. Moreover, the treatment of bronchobiliary fistula should be prompt to cease pneumonia progression. Therefore, we introduce this rare complication of post-TACE bronchobiliary fistula in hopes that future clinicians will keep earlier intervention in mind.

Combined Liver Stiffness and Α-fetoprotein Further beyond the Sustained Virologic Response Visit as Predictors of Long-Term Liver-Related Events in Patients with Chronic Hepatitis C.

Aims: Long-term risk stratification using combined liver stiffness (LS) and clinically relevant blood tests acquired at the baseline further beyond the sustained virologic response (SVR) visit for chronic hepatitis C (CHC) has not been thoroughly investigated. This study retrospectively investigated the prognostics of liver-related events (LREs) further beyond the SVR visit. Methods: Cox regression and random forest models identified the key factors, including longitudinal LS and noninvasive test results, that could predict LREs, including hepatocellular carcinoma, during prespecified follow-ups from 2010 to 2021. Kaplan-Meier survival analysis estimated the significance of between-group risk stratification. Results: Of the entire eligible cohort (n = 520) of CHC patients with SVR to antiviral therapy, 28 (5.4%) patients developed post-SVR LREs over a median follow-up period of 6.1 years (interquartile range = 3.5-8.7). The multivariate Cox regression analysis identified two significant predictors of LREs after the year 3 post-SVR (Y3PSVR) baseline (LRE, n = 15 of 28, 53.6%, median follow-up = 4.1 [1.6-6.4] years after Y3PSVR): LS at Y3PSVR (adjusted hazard ratio [aHR] = 3.980, 95% confidence interval [CI] = 2.085-7.597, P < 0.001), and α-fetoprotein (AFP) at Y3PSVR (aHR = 1.017, 95% CI = 1.001-1.034, P=0.034). LS ≥1.45 m/s and AFP ≥3.00 ng/mL for Y3PSVR yielded positive likelihood ratios of 4.24 and 2.62, respectively. Kaplan-Meier analysis revealed that among the stratified subgroups, the subgroup with concurrent LS ≥1.45 m/s and AFP ≥3.00 ng/mL at Y3PSVR exhibited the highest risk of LREs after Y3PSVR (log-rank P < 0.001). Conclusion: We recommend the combined use of concurrent LS and AFP in future prediction models for LREs in CHC. Patients with concurrently high LS and AFP values further beyond the SVR visit may require a recall policy involving intense surveillance.

Posttreatment nonalcoholic fatty liver disease fibrosis scores for predicting liver-related complications in patients with chronic hepatitis C receiving direct-acting antiviral agents.

Patients with chronic hepatitis C (CHC) have a higher prevalence of hepatic steatosis and dyslipidaemia than healthy individuals. We analysed noninvasive fibrosis assessments, especially nonalcoholic fatty liver disease (NAFLD)-related noninvasive fibrosis tests, for predicting liver-related complications and hepatocellular carcinoma (HCC) occurrence in patients with CHC. This retrospective study enrolled 590 consecutive patients with CHC having a sustained virologic response (SVR) to direct-acting antiviral agent (DAA) therapy. The NAFLD fibrosis score (NFS) exhibiting the highest value of area under the receiver operating characteristic curve (AUROC) was selected for comparison with the fibrosis-4 index (FIB-4). Of the 590 patients, 188 had metabolic syndrome. A multivariate Cox regression analysis identified total bilirubin at 3 or 6 months after DAA therapy (PW12), NFS at PW12 (hazard ratio [HR]: 2.125, 95% confidence interval [CI]: 1.058-4.267, p = .034) and alpha-fetoprotein (AFP) at PW12 (HR: 1.071, 95% CI: 1.005-1.142, p = .034) as the independent predictors of liver-related complications in all patients. In patients with metabolic syndrome, NFS and AFP values at PW12 were independent predictors of liver-related complications and HCC occurrence. Time-dependent NFS AUROC values at PW12 for 1-, 2- and 3-year liver-related complications were higher than NFS values at baseline in patients with metabolic syndrome. NFS at baseline or PW12 is a more effective predictor of liver-related complications than FIB-4 values in all patients. NFS at PW12 may be a useful predictor of liver-related complications and HCC development in patients with CHC with an SVR to DAA therapy, especially in those with metabolic syndrome.

Liver and Spleen Stiffness Surveillance Through Elastography During and After Direct-Acting Antiviral Therapy in Patients With Chronic Hepatitis C.

OBJECTIVES: Direct-acting antiviral agents achieve a high cure rate, resulting in early hepatic necroinflammatory resolution and sustained fibrosis regression. This study aimed to obtain longitudinal, concurrent within-subject measurements of liver stiffness (LS) and spleen stiffness (SS) and their correlates over time. METHODS: Participants with hepatitis C (n = 592) receiving direct-acting antiviral-based therapy were monitored through point shear-wave elastography from the treatment baseline (TW0) across follow-up visits in terms of LS and SS. RESULTS: Generalized linear mixed modeling indicated that all LS values (2301 visits) were negatively correlated with the follow-up times (all P < .05) from TW0 to 24 weeks (PW24) after the end of treatment (EOT) and positively correlated with baseline LS values (P < .001). The slopes of declines (preceding minus next) differed significantly (P < .001) between TW0-TW4 (treatment week 4) (0.060 [-0.050 to 0.225] meter/second/month [m/s/mo]) and TW4-EOT (0.010 [-0.030 to 0.075] m/s/mo). All SS values (1704 visits) were negatively correlated with time only at PW24 (P < .001) and positively correlated with baseline SS values (P < .001). The slopes of the SS values differed significantly (P < .001) only between EOT-PW12 (-0.010 [-0.110 to 0.083] m/s/mo) and PW12-PW24 (0.043 [-0.063 to 0.160] m/s/mo). CONCLUSIONS: The biphasic fast-to-slow decline in LS occurred early in the on-treatment phase, which is consistent with the resolution of hepatic necroinflammation. The slow-to-fast decline in SS occurred off treatment. Future studies should investigate the association with regressions in liver fibrosis and portal hypertension.

Alpha-fetoprotein response predicts treatment outcomes in patients with unresectable hepatocellular carcinoma receiving immune checkpoint inhibitors with or without tyrosine kinase inhibitors or locoregional therapies.

Combined immune checkpoint inhibitors (ICIs) along with tyrosine kinase inhibitors (TKIs) and locoregional therapies have been used increasingly to treat hepatocellular carcinoma (HCC). Biomarkers are required to predict the treatment efficacy of ICIs with or without combination therapies in patients with unresectable HCC. This study enrolled 95 consecutive patients with unresectable HCC from May 2017 to June 2021 from two hospitals retrospectively. Of the 95 patients, 15 and 80 had Barcelona Clinic Liver Cancer stages B and C, respectively. The median ICI treatment duration was 3.43 (1.87-7.87) months, and 77 patients received combination therapies. Radiological imaging was not performed in 13 patients. Objective response and disease control rates were 27.4% and 53.7%, respectively. The duration of progression-free survival (PFS) and overall survival (OS) was 4.07 (1.59-6.54) months and 14.53 (6.93-22.14) months, respectively. Alpha-fetoprotein (AFP) response was defined as a decline of >15% in the serum AFP level within the initial 3 months of ICI therapy according to Youden's index. AFP response was determined to be a predictor of disease control (odds ratio: 11.657, 95% confidence interval [CI]: 2.834-47.941, P=.001). Macrovascular invasion (MVI), AFP response (hazard ratio [HR]: 0.488, 95% CI: 0.255-0.934, P=.030), combination therapy, and disease control were predictors of PFS, and MVI, AFP response (HR: 0.344, 95% CI: 0.160-0.737, P=.006), and disease control were predictors of OS. AFP response was a predictor of disease control, PFS, and OS. These findings indicate that AFP response can serve as a biomarker to predict treatment outcomes in patients with unresectable HCC receiving ICIs with or without TKIs or locoregional therapies.

Predictors of response and survival in patients with unresectable hepatocellular carcinoma treated with nivolumab: real-world experience.

Real-world predictors of the treatment efficacy of immune checkpoint inhibitors for hepatocellular carcinoma (HCC) are unknown. This retrospective study enrolled 87 consecutive patients with unresectable HCC from May 2017 to December 2019 at two hospitals. Of the 87 patients, 7, 9, 60, and 11 patients had Barcelona Clinic Liver Cancer stages A, B, C, and D, respectively, and 45, 30, and 10 patients were Child-Pugh class A, B, and C, respectively. The median injection numbers of nivolumab and treatment duration were 6 (3-8) and 2.53 (1.47-4.23) months, respectively, and 64.4% of patients received combination therapy. Radiological imaging was not assessed for 25 patients. Objective response (OR) and disease control rates were 19.5% and 39.1%, respectively. A single tumor (odds ratio: 9.542, P = .015) and ≥20% decline in serum α-fetoprotein protein (AFP) levels within the first 3 months of treatment (defined as AFP response, odds ratio: 5.997, P = .042) were predictors of OR. Lack of macrovascular invasion, combination therapy, and AFP response were predictors of progression-free survival. A Cancer of the Liver Italian Program (CLIP) score of 0-2 (hazard ratio [HR]: 3.717, P = .004) and grade 1-2 immune-related adverse events (irAEs, HR: 2.217, P = .049) were predictors of overall survival (OS) in the entire cohort, and a CLIP score of 0-2 (HR: 3.257, P = .009) was a predictor of OS in evaluable patients. IrAEs ≥ grade 3 were noted in 14 patients, and three died as a result. Having a single tumor and AFP response were predictors of OR, and CLIP score was a predictor of OS.

Performance of Acoustic Radiation Force Impulse Elastography for Staging Liver Fibrosis in Patients With Chronic Hepatitis C After Viral Eradication.

BACKGROUND: Data on noninvasive liver fibrosis staging after viral eradication are unclear. This histology-based study validated the performance of liver stiffness (LS) measurements after viral eradication. METHODS: Consecutive participants with chronic hepatitis C (CHC) who received concomitant LS measurements through acoustic radiation force impulse (ARFI) elastography and percutaneous liver biopsy were prospectively screened and analyzed. RESULTS: Of the 644 patients, 521 (80.9%) underwent a biopsy at treatment baseline, and the remaining 123 (19.1%) underwent a biopsy at 3 years (median; interquartile range, 0.1) after the sustained virological response (SVR) to pegylated interferon-based and direct-acting antiviral treatments. The proportions of histological fibrosis stages did not differ significantly between the pretreatment and post-SVR groups (P = .0615). However, the LS values differed significantly (P < .0001). The median LS values (presented as shear wave velocities in meters per second) were 1.51 (0.92) for the pretreatment group and 1.22 (0.77) for the post-SVR group. The cutoffs (areas under the receiver operating characteristic curve, obtained using the bootstrap method) to dichotomize between METAVIR fibrosis stage F1 versus stages F2-F4, F1-F2 versus F3-F4, and F1-F3 versus F4 were 1.47 (0.8333, 95% confidence interval [CI] 0.7981-0.8663), 1.81 (0.8763, 95% CI 0.8376-0.9107), and 1.86 (0.8811, 95% CI 0.8378-0.9179) in the pretreatment group, respectively, and 1.22 (0.7872, 95% CI 0.7001-0.8624), 1.59 (0.8808, 95% CI 0.8034-0.9422), and 1.75 (0.9018, 95% CI 0.8201-0.9644) in the post-SVR group, respectively. CONCLUSIONS: The performance of LS measurements through ARFI elastography is promising to determine the liver fibrosis stage on necroinflammation-resolved histology in CHC after viral eradication.

Rapid decline of noninvasive fibrosis index values in patients with hepatitis C receiving treatment with direct-acting antiviral agents.

BACKGROUND: Studies on temporal changes in noninvasive fibrosis indices and liver stiffness measurement (LSM) in patients with chronic hepatitis C (CHC) treated with direct-acting antiviral agents (DAAs) are limited. METHODS: We retrospectively enrolled consecutive patients with CHC who had received DAAs. RESULTS: In total, we recruited 395 consecutive patients, of which 388 (98.2%) achieved a sustained virologic response (SVR) at 12 weeks after therapy. In patients who received DAA therapy and achieved SVR 12 weeks after therapy (n = 388), the median aspartate aminotransferase/platelet ratio index (APRI) value decreased from 1.19 (0.62-2.44) at baseline to 0.50 (0.32-0.95), 0.51 (0.31-0.92), 0.48 (0.31-0.88), and 0.52 (0.33-0.92) at week 2, week 4, end of therapy, and PW12, respectively (all P < 0.001). The median FIB-4 value decreased from 2.88 (1.56-5.60) at baseline to 2.10 (1.30-3.65), 2.15 (1.30-3.65), 2.11 (1.37-3.76), and 2.22 (1.45-3.82) at week 2, week 4, end of therapy, and PW12, respectively (all P < 0.001). The median alanine aminotransferase level significantly decreased from week 2 until PW12 (all P < 0.001). The platelet count significantly increased from 2 weeks after DAA therapy initiation until PW12 (all P < 0.001); however, the magnitude of changes in the platelet count was low. In patients with paired LSMs obtained using acoustic radiation force impulse elastography at baseline and PW12 (n = 199), the median LSM decreased from 1.78 (1.25-2.30) m/s at baseline to 1.38 (1.14-1.88) m/s at PW12 (P < 0.001). CONCLUSIONS: Noninvasive fibrosis indices, namely APRI and FIB-4, exhibited a rapid and sustained decline from week 2 until PW12 in patients with CHC who achieved SVR to DAA therapy. The rapid decline in APRI and FIB-4 values might mainly result from improvement in necroinflammation.

Changes in liver stiffness measurement using acoustic radiation force impulse elastography after antiviral therapy in patients with chronic hepatitis C.

BACKGROUND: To compare on-treatment and off-treatment parameters acquired using acoustic radiation force impulse elastography, the Fibrosis-4 (FIB-4) index, and aspartate aminotransferase-to-platelet ratio index (APRI) in patients with chronic hepatitis C (CHC). METHODS: Patients received therapies based on pegylated interferon or direct-acting antiviral agents. The changes in paired patient parameters, including liver stiffness (LS) values, the FIB-4 index, and APRI, from baseline to sustained virologic response (SVR) visit (24 weeks after the end of treatment) were compared. Multiple regression models were used to identify significant factors that explained the correlations with LS, FIB-4, and APRI values and SVR. RESULTS: A total of 256 patients were included, of which 219 (85.5%) achieved SVR. The paired LS values declined significantly from baseline to SVR visit in all groups and subgroups except the nonresponder subgroup (n = 10). Body mass index (P = 0.0062) and baseline LS (P < 0.0001) were identified as independent factors that explained the LS declines. Likewise, the baseline FIB-4 (P < 0.0001) and APRI (P < 0.0001) values independently explained the declines in the FIB-4 index and APRI, respectively. Moreover, interleukin-28B polymorphisms, baseline LS, and rapid virologic response were identified as independent correlates with SVR. CONCLUSIONS: Paired LS measurements in patients treated for CHC exhibited significant declines comparable to those in FIB-4 and APRI values. These declines may have correlated with the resolution of necroinflammation. Baseline LS values predicted SVR.
