Impact of steroid therapy on pediatric acute liver failure: prognostic implication and interplay between TNF-α and miR-122.

Background: Acute liver failure (ALF) is a rare illness marked by rapid deterioration of liver function, leading to high morbidity and mortality rates, particularly in children. While steroids have been observed to correlate with improved survival, evidence supporting their efficacy in ALF children remains limited. miR-122, a liver-specific microRNA, plays a pivotal role in liver pathology, with its expression significantly altered in various liver diseases.

SOX9 in biliary atresia: New insight for fibrosis progression.

Background: Liver fibrosis is a hallmark determinant of morbidity in biliary atresia (BA) even in successfully operated cases. Responsible factors for this rapid progression of fibrosis are not completely defined. Aberrant expression of the transcription factor SOX9 and hepatic progenitor cells (HPCs) proliferation have roles in fibrogenesis in cholestatic disorders.

Temporal histopathological changes in biliary atresia: A perspective for rapid fibrosis progression.

Introduction And Objectives: Biliary atresia (BA) is characterized by rapid progression of fibrosis with no definite causes. Histopathological findings have been extensively described, but very few studies have assessed temporal changes in BA. Understanding these short-term changes and their relationship with fibrosis progression could have an impact on ameliorating rapid fibrogenesis.

Safety and Efficacy of 8 Weeks Ledipasvir/Sofosbuvir for Chronic Hepatitis C Genotype 4 in Children Aged 4-10 Years.

Objective: To evaluate the safety and efficacy of shortened 8-week regimen of ledipasvir/sofosbuvir (LED/SOF) combination therapy in treatment-naïve children without cirrhosis aged 4-10 years of age with chronic hepatitis C virus (HCV) infection.

Study Design: This observational single arm prospective study included 30 treatment-naïve children (20 males) with proved chronic HCV fulfilling inclusion criteria. Their body weights ranged from 17 to 26 kg.

Generic sofosbuvir/ledipasvir for the treatment of genotype 4 chronic hepatitis C in Egyptian children (9-12 years) and adolescents.

Background/purpose Of The Study: Worldwide and national efforts are directed against eradication of HCV. The introduction of direct-acting antivirals (DAAs) has changed dramatically the outcome of HCV treatment. In spite of the Food and Drug Administration approval of the oral drugs sofosbuvir (SOF) and ledipasvir (LED) for the treatment of HCV in adolescents more than or equal to 12 years old, sufficient real-world experience is still lacking.
