Liver disease in children

Chronic viral hepatitis causes an increased risk of progressive liver disease and hepatocellular carcinoma. On the wave of the World Health Organization's goal to reduce new cases and deaths from hepatitis B and C by 2030, there is an increasing call to expand the indications for treatment of chronic hepatitis B. Currently, the main goal of treatment is to achieve a functional cure due to the inability of current drugs to completely eradicate the virus. There are still many discrepancies between available guidelines in terms of eligibility for treatment as well as an uncertainty about the appropriate treatment duration...

RESULTS: In all, 47 patients were studied, 25 (53.2%) patients had disease reactivation and 22 (46...

UNLABELLED: Hepatic steatosis has become the most common cause of chronic liver disease among children worldwide.  Lipophagy has been considered as a pathway affecting steatosis development and progression. OBJECTIVE: this study aimed to evaluate the immunohistochemical expression of Beclin1 and LC3A in pediatric hepatic tissues with steatosis and to correlate their expression with clinicopathological parameters. METHODS: this study included 81 Egyptian pediatric patients with hepatic steatosis and 21 pediatric cases without hepatic steatosis...

BACKGROUND & AIMS: The authors assess the diagnostic accuracy of the Transient Elastography-Controlled Attenuation Parameter (TE-CAP) in children of Southern China. METHODS: 105 obese or overweight children and adolescents were enrolled in the diagnostic test of TE-CAP assessment of hepatic steatosis using MRI-PDFF. Hepatic steatosis grades S0-S3 were classified. Statistical correlation, agreement and consistency between methods were evaluated. The diagnostic efficiency of TE-CAP was evaluated...

OBJECTIVES: We performed a single-centre retrospective study comparing the accuracy of non-invasive elastography with liver biopsy in accurate assessment of Fontan-associated liver disease. METHODS: Fontan patients who underwent combined assessment with a percutaneous liver biopsy and non-invasive elastography between January 2015 and December 2023 at our Children's hospital were included. Liver biopsies were classified using the Congestive Hepatic Fibrosis Score as early Fontan-associated liver disease (scores 1, 2) and advanced Fontan-associated liver disease (score 3/bridging fibrosis and score 4/cirrhosis)...

OBJECTIVES: Alkaline phosphatase (ALP) can be increased in a benign condition known as benign-transient hyperphosphatasemia (BTH). We aimed to evaluate the demographic, and clinical characteristics of infants and children with BTH. METHODS: In our retrospective study, infants and children diagnosed with BTH between September 2019 and September 2023 were included. RESULTS: Of 249 children with elevated ALP levels, 95 (38.1 %) had BTH...

RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease characterized by excessive immune activation. It is more commonly seen in children but increasingly recognized in adults. Primary HLH relies on a genetic predisposition, whereas secondary HLH develops in the context of infections, malignancies, or autoimmune diseases. Hemophagocytic lymphohistiocytosis has been rarely described in patients on immunosuppressive therapy after kidney transplant. Here, we describe a case of HLH in a patient with a remote history of kidney transplant, triggered by a viral infection...

BACKGROUND: Neonatal Intrahepatic Cholestasis (NICCD), as the early-age stage of Citrin deficiency involving liver dysfunction, lacks efficient diagnostic markers. Procalcitonin (PCT) has been identified as a biomarker for infection as well as various organ damage. This study aimed to explore the potential of PCT as a biomarker for NICCD. METHODS: In a single-center retrospective case-control study. Serum PCT concentrations before and after treatment of 120 NICCD patients, as the study group, were compared to the same number of cholestatic hepatitis patients, as the control group...

BACKGROUND AND AIMS: An increase in the number of cases of acute hepatitis of unknown origin (HUO) in children was observed in 2021. Adenovirus and adeno-associated virus 2 (AAV2) infections have been suggested as possible triggers. However, the potential etiology is still unclear. We aimed to characterize a cohort of children with HUO in Israel in view of the COVID-19 pandemic. METHOD: Demographics, clinical data, and laboratory results on the children compatible with the CDC criteria for HUO were collected by the established registry of the Ministry of Health...

BACKGROUND: Hepatitis A virus (HAV) infection is the commonest cause of pediatric acute liver failure (PALF) in developing countries. Literature has shown good outcomes of HAV-induced PALF as compared to other etiologies. The advanced critical care and use of extracorporeal liver assist devices (ELAD) have improved the survival with native liver in PALF and overall outcomes. Various liver transplant listing criteria have been proposed in PALF, however none of them is specific enough to predict the outcome...

Historically vitamin D deficiency had devastating consequences for children causing rickets resulting in severe bone deformities often leading to death. The mystery of the cause of rickets finally came to light when it was observed that cod liver oil and sunlight could prevent and cure rickets. The first vitamin D to be discovered was vitamin D2 from ergosterol in ultraviolet irradiated yeast. Vitamin D3 was discovered from UV exposure to the skin. Investigations revealed the two major functions of vitamin D were to increase intestinal calcium and phosphate absorption and mobilize calcium from the skeleton to maintain calcium and phosphorus homeostasis...

Autoimmune hepatitis (AIH) is a chronic, inflammatory liver disease of unknown aetiology which requires lifelong immunosuppression. Most therapeutic and outcome studies of AIH have been conducted predominantly in Caucasian (European Ancestry, EA) cohorts, with the exclusion of African American (AA) patients due to inadequate sample size. It is known that AA patients have a severe phenotype of autoimmune diseases and demonstrate a poor response to conventional medical therapy. Understanding cellular and molecular pathways which determine AIH severity and progression in AA patients is likely to lead to the discovery of novel, personalised and better tolerated therapies...

AIM OF THE STUDY: To investigate whether serum ferritin and vitamin D levels before starting autoimmune hepatitis (AIH) treatment have a role in disease prognosis regarding a therapeutic response. MATERIAL AND METHODS: The prospective study included 100 children diagnosed with AIH according to simplified criteria for diagnosis of AIH. They attended the Pediatric Hepatology Department, National Liver Institute, Menoufia University. The patients underwent measurement of liver transaminases before starting AIH treatment after 6 months from starting therapy...

Hepatoblastoma is the most common hepatic neoplasm in children. However, its incidence is infrequent beyond age five. We present the case of a 15-year-old female diagnosed with metastatic hepatoblastoma during hospitalization for liver function deterioration. The patient presented with abdominal distension, jaundice, and other symptoms indicative of advanced disease. Imaging and biopsy confirmed stage IV epithelial hepatoblastoma with pulmonary metastases. This case underscores the importance of considering hepatoblastoma in older pediatric patients or young adults presenting with hepatic masses despite lacking traditional risk factors for liver malignancies...

INTRODUCTION: Acute liver failure (ALF), although rare in children, is a complex progressive pathology, with multisystem involvement and high mortality. Isolated variables or those included in prognostic scores have been studied, to optimize organ allocation. However, its validation is challenging. This study aimed to assess the accuracy of several biomarkers and scores as predictors of prognosis in pediatric ALF (PALF). METHODS: An observational study with retrospective data collection, including all cases of ALF, was defined according to the criteria of the Pediatric Acute Liver Failure Study Group, admitted to a pediatric intensive care unit (PICU) for 28 years...

Celiac crisis (CC) is a rare complication of celiac disease (CD), usually observed in younger children with unrecognized CD or poor compliance with a gluten-free diet (GFD). We present a case of celiac crisis in a 3-year-old girl who was recently diagnosed with celiac disease. She was referred to our clinic with anasarca, tetany, and severe malnutrition, with hypokalemia, hypocalcemia, hypomagnesemia, and hypoalbuminemia. During hospitalization, she presented hypertransaminasemia with positive anti-actin smooth muscle antibodies (SMA)...

OBJECTIVES: The goal of this longitudinal study was to reduce anxiety and pain in children with chronic conditions from the gastrointestinal tract during venipuncture. These children undergo regular venipuncture as part of their medical management and the procedure is often accompanied with anxiety and pain. In addition, children as well as their parents and health care professionals (HCPs) often suffer "compassionate pain" because of emotional interference. METHOD: In a realistic clinical setting, different psychological and medical interventions were examined: (1) Psychoeducational brochures and (2) four different medical-technical interventions during venipuncture...

OBJECTIVES: Characterize the clinicopathologic features of liver biopsies from patients with celiac disease (CD).
