Abstract
Background
Abnormal extracellular matrix (ECM) turnover is linked to liver fibrosis as it reflects an imbalance between repair and progressive substitution of the liver parenchyma by scar tissue. Matrix metalloproteinases (MMPs) are the primary enzymes involved in ECM breakdown. So, this study aims to measure the value of serum matrix metalloproteinase-1 (MMP-1) in children with chronic liver diseases (CLD) in comparison with liver biopsy and serum biomarkers. A hundred twenty children with chronic liver diseases and sixty healthy children as a control group were included in this study. Both groups were evaluated via medical history, clinical, radiological, laboratory investigations, and serum MMP-1 level was measured by ELISA. Liver biopsy was performed for studied patients only.
Results
The mean MMP-1 was 15.2 ± 5.1 ng/ml in children with CLD, and 64.7 ± 27.4 ng/ml in the control group. MMP-1 was statistically lower in the children with CLD than controls (p < 0.001). The mean ± SD of aspartate aminotransferase to platelet ratio index (APRI) and fibrosis-4 (FIB-4) scores in all studied cases showed a significant trend of increase with progressive fibrosis stage evident with histological METAVIR scoring system, while serum MMP-1 concentration was decreased significantly with increasing the degree of fibrosis in CLD group (P 0.001). Serum MMP-1 was indirectly correlated with serum biomarkers and the degree of fibrosis in patients.
Conclusions
MMP-1 is a useful non-invasive marker for detection of the stage of liver fibrosis in children with chronic liver diseases.

Improvement in Liver Stiffness in Pediatric Patients with Hepatitis C Virus after Treatment with Direct Acting Antivirals. J Pediatr 2021; 233:126-131. [PMID: 33577805 DOI: 10.1016/j.jpeds.2021.02.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Revised: 02/04/2021] [Accepted: 02/05/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVES To assess the degree of liver stiffness using transient elastography in Egyptian children infected with hepatitis C virus (HCV) at baseline and 1 year after achievement of sustained virologic response (SVR) with direct acting antivirals. STUDY DESIGN This prospective study included children infected with HCV who received treatment with sofosbuvir/ledipasvir and achieved SVR. At baseline and 1 year after achievement of SVR, the extent of hepatic fibrosis was assessed by transient elastography using FibroScan to measure liver stiffness, in addition to noninvasive markers including aspartate aminotransferase/platelet ratio index (APRI) and fibrosis-4 (FIB-4) index. RESULTS The study included 23 cases that had variable degrees of fibrosis at baseline; their ages ranged between 10 and 18 years. At baseline, 13 patients had F1; 3 patients had F1-F2; 1 patient had F2; 3 patients had F3; 2 had F3-F4; and 2 patients with F4. One year after achievement of SVR, there was a statistically significant improvement in liver stiffness, APRI, and FIB-4 index (P = .03, <.001, .02, respectively). In 13 patients (56.5%), the liver stiffness improved; in 7 patients, it was stationary; and the remaining 3 patients showed mild increase in liver stiffness that was, however, associated with improvement in APRI and FIB-4 index. Comorbid conditions and previous treatment with interferon were not associated with increased liver stiffness 1 year after SVR. CONCLUSIONS Egyptian children infected with HCV genotype 4 achieved significant regression in liver stiffness after treatment with direct acting antivirals.

Progress and Barriers Towards Elimination of Chronic Hepatitis C in Children. KLINISCHE PADIATRIE 2020; 233:211-215.

Abstract
Chronic hepatitis C (CHC) is a global health burden. Mother-to-child transmission (MTCT) accounts for most HCV infections in pediatric patients. Spontaneous viral clearance may occur in early childhood but is uncommon thereafter. Infection is usually asymptomatic during childhood, although without an effective treatment, vertically infected children may develop serious liver complications including cirrhosis and hepatocellular carcinoma in adulthood. Despite the lack of vaccine against hepatitis C and effective post-exposure methods of prevention of MTCT, treatment with direct-acting antiviral agents (DAAs) raised the prospect of eliminating HCV on a population level. Highly effective, well-tolerated, oral, and interferon-free regimens of short duration have revolutionized treatment of CHC. However, access to these therapies might be limited because of its high cost. In this review, we provide the current state of knowledge on the epidemiology, testing, monitoring and treating of HCV in children. We outline the remaining gaps in therapy and barriers to disease eradication.

Abstract
Fibrosing diseases are causes of morbidity and mortality around the world, and they are characterized by excessive extracellular matrix (ECM) accumulation. The bHLH transcription factor scleraxis (SCX) regulates the synthesis of ECM proteins in heart fibrosis. SCX expression was evaluated in lung fibroblasts and tissue derived from fibrotic disease patients and healthy controls. We also measured SCX in sera from 57 healthy controls, and 56 Idiopathic Pulmonary Fibrosis (IPF), 40 Hypersensitivity Pneumonitis (HP), and 100 Systemic Sclerosis (SSc) patients. We report high SCX expression in fibroblasts and tissue from IPF patients versus controls. High SCX-serum levels were observed in IPF (0.663 ± 0.559 ng/mL, p < 0.01) and SSc (0.611 ± 0.296 ng/mL, p < 0.001), versus controls (0.351 ± 0.207 ng/mL) and HP (0.323 ± 0.323 ng/mL). Serum levels of the SCX heterodimerization partner, TCF3, did not associate with fibrotic illness. IPF patients with severely affected respiratory capacities and late-stage SSc patients presenting anti-topoisomerase I antibodies and interstitial lung disease showed the highest SCX-serum levels. SCX gain-of-function induced the expression of alpha-smooth muscle actin (α-SMA/ACTA2) in fibroblasts when co-overexpressed with TCF3. As late and severe stages of the fibrotic processes correlated with high circulating SCX, we postulate it as a candidate biomarker of fibrosis and a potential therapeutic target.

Abstract
The purpose of this study was to investigate the correlations between Gd-EOB-DTPA DCE-MRI biomarkers and histopathologic biomarkers of liver fibrosis progression in a rabbit model of liver fibrosis. Thirty-Six New Zealand white rabbits were randomly divided into control (n = 6) and liver fibrosis group (n = 30). Each rabbit in the liver fibrosis group received a weekly subcutaneous injection in the back comprising 50% carbon tetrachloride (CCl4) in oily solution. Control rabbits received subcutaneous injections with the same amount of normal saline solution instead. MR imaging was performed in control and fibrotic rabbits were conducted by MRI at week 0 (n = 36). The fibrotic rabbits were performed MR imaging on 6 weeks, 9 weeks, and 12 weeks after modeling of fibrosis. Before each MRI, peripheral blood was collected, and several biochemical testes are performed. The thirty-four rabbits completed this study. They were then divided into three subgroups according to fibrotic stage: no fibrosis (F0, n = 12), mild fibrosis (F1+F2, n = 14), and advanced fibrosis (F3+F4, n = 8). DCE-MRI measurements show increasing Ktrans and Ve while decreasing iACU90 with increasing fibrosis stage. The significant correlations were observed between mean Ktrans, Ve, iACU90 and percentage of the animal with mild liver fibrosis. For blood biomarkers, there were significant differences between F0 and F1+F2, and between F0 and F3+F4 in the serum levels of ALT (all P < 0.05), and TB (F0 vs. F1+F2, P = 0.004), while no differences were found between F1+F2 group and F3+F4 group (all P > 0.05). There were significant differences between F0 and F1+F2 (P = 0.02). Gd-EOB-DTPA DCE-MRI is a promising method for the noninvasive diagnosis and staging of liver fibrosis. Future studies to evaluate the effectiveness of these techniques in patients with liver fibrosis are warranted.
