infant hepatitis

H Agut, P Bonnafous, A Gautheret-Dejean
Human herpesviruses 6A, 6B, and 7 (HHV-6A, HHV-6B, HHV-7) are genetically related to cytomegalovirus. They belong to the Roseolovirus genus and to the Betaherpesvirinae subfamily. They infect T cells, monocytes-macrophages, epithelial cells, and central nervous system cells. These viruses are ubiquitous and are responsible for lifelong chronic infections, most often asymptomatic, in the vast majority of the general adult population. HHV-6B is responsible for exanthema subitum, which is a benign disease of infants...

Since the global Expanded Program on Immunization (EPI) was launched in 1974, vaccination against six diseases (tuberculosis, polio, diphtheria, tetanus, pertussis, and measles) has prevented millions of deaths and disabilities (1). Significant advances have been made in the development and introduction of vaccines, and licensed vaccines are now available to prevent 25 diseases (2,3). Historically, new vaccines only became available in low-income and middle-income countries decades after being introduced in high-income countries...

AIM: Compare efficacy, immunogenicity and safety of Hepavax-Gene TF (thimerosal free) vaccine with comparator in Chinese neonates. METHODS: Double-blind, randomized, parallel-group, stratified study was conducted at multiple sites in China in healthy neonates, consisting of three doses of Hepavax-Gene TF or Engerix-B vaccines administered at birth, one and six months of age, with a six month follow-up after vaccination. Based on hepatitis B virus (HBV) infection status of mothers, infants were assigned to one of two study strata for mothers positive for HBV infection (Stratum 1), with or without active replicating virus (Substrata 1a, 1b) and for HBV negative mothers (Stratum 2)...

Breast milk is considered ideal food for premature infants, but it can also be the main source of cytomegalovirus (CMV) infection in premature infants. CMV infection may cause serious clinical symptoms, such as sepsis-like syndrome, thrombocytopenia, neutropenia, jaundice, hepatitis, and pneumonitis. This article reviews the research advances in symptoms, treatment strategies, prognosis and the prevention of breast milk-acquired CMV infection in premature infants.

Integration of hepatitis B vaccination into national immunization programs has resulted in substantial reductions of hepatitis B virus (HBV) transmission in previously high endemic countries. The key strategy for control of the HBV epidemic is birth dose and infant vaccination. Additional measures include use of hepatitis B immunoglobulin (HBIG) and diagnosis of mothers at high risk of transmitting HBV and use of antiviral agents during pregnancy to decrease maternal DNA concentrations to undetectable concentrations...

Infants born to human immunodeficiency virus (HIV) infected women are HIV-exposed but the majority remains uninfected [i.e., HIV-exposed uninfected (HEU)]. HEU infants suffer greater morbidity and mortality from infections compared to HIV-unexposed (HU) peers. The reason(s) for these worse outcomes are uncertain, but could be related to an altered immune system state. This review comprehensively summarizes the current literature investigating the adaptive and innate immune system of HEU infants. HEU infants have altered cell-mediated immunity, including impaired T-cell maturation with documented hypo- as well as hyper-responsiveness to T-cell activation...

In Taiwan, infants need to receive 3 doses of hepatitis B virus (HBV) vaccine under the public health policy from the government. However, there are many young adults who even though received complete HBV vaccination in their childhood would lose the positive response of anti-hepatitis B surface antibody (HBs) and need the booster dose of HBV vaccine. The aim of our study is to determine the powerful predictive factor for screening the candidates who need only 1 booster dose of HB vaccine then they can regain positive postbooster anti-HBs status (≧10 mIU/mL) or protective postbooster anti-HBs status (≧100 mIU/mL)...

BACKGROUND: Member states of the World Health Organization have adopted resolutions aiming to achieve 'no increase on obesity levels' by 2025 (based on 2010 levels) for infants, adolescents and adults. OBJECTIVES: We aimed to assess the scale of the problem facing health planners and service providers. METHODS AND RESULTS: Using data prepared by the Global Burden of Disease collaborative for 2000 and 2013, we have estimated that by 2025 some 268 million children aged 5-17 years may be overweight, including 91 million obese, assuming no policy interventions have proven effective at changing current trends...

BACKGROUND: Vascular complications following pediatric liver transplantation occur in 8-10% of cases, and no continuous, non-invasive monitoring for this problem exists. Near infrared spectroscopy (NIRS) allows non-invasive, continuous, transcutaneous assessment of hemoglobin oxygenation (StO2 ) 1-4 cm below the skin surface. AIMS: We hypothesized that transcutaneous NIRS would be able to detect severe hepatic ischemia, and tested this in an animal model using 15-20 kg and 5-7 kg juvenile pigs...

BACKGROUND: Despite extensive research the genetic component of extremely low birth weight (ELBW) in newborns has remained obscure. RESULTS: The aim of the case study was to identify candidate gene(s) causing ELBW in newborns and hypotrophy in infants. A family of four was studied: mother, father and two ELBW-phenotype children. Studies were made of the medical conditions of the second child at birth and post-partum - peculiar phenotype, micro-anomalies, recurrent infections, suspicion of autoimmune hepatitis, multifactorial encephalopathy and suspected metabolic and chromosomal abnormalities...

Cholestasis in early infancy represents a diagnostic dilemma and most of these infants suffer either from extrahepatic biliary atresia or idiopathic neonatal hepatitis. Differentiation between the two conditions may be extremely difficult both clinically and biochemically, and a diagnostic liver biopsy is usually required. We report on a Sudanese infant who presented at the age of 4 weeks with prolonged cholestatic jaundice, abdominal ultrasound was inconclusive, HIDA scan was suggestive of extrahepatic biliary atresia and the diagnosis of idiopathic neonatal hepatitis was only reached by liver biopsy...

: Repeating evaluations of vaccine coverage (VC) is essential to measure the implementation and effectiveness of vaccination policy. We report the results of VC in infants from the Vaccinoscopie(®) study in 2014 to assess the changes secondary to the new 2013 immunization schedule. METHOD: Study conducted on Internet among a representative sample of mothers reporting their child's vaccination record. RESULTS: The removal of the dose of DTPa-Hib at the age of 3 months was quickly adopted since only 1 % of children aged 6 months had received three doses of DTPa in 2014 compared to 96 % in 2012...

Very-long-chain acyl-CoA dehydrogenase (VLCAD) catalyzes the first reaction in the mitochondrial fatty acid β-oxidation pathway. VLCAD deficiency is associated with the accumulation of fat in multiple organs and tissues, which results in specific clinical features including cardiomyopathy, cardiomegaly, muscle weakness, and hepatic dysfunction in infants. We speculated that the abnormal fatty acid metabolism in VLCAD-deficient individuals might cause cell necrosis by fatty acid toxicity. The accumulation of fatty acids may activate peroxisome proliferator-activated receptor (PPAR), a master regulator of fatty acid metabolism and a potent nuclear receptor for free fatty acids...

: Biliary atresia is a fibroinflammatory obstruction of the extrahepatic biliary tree in neonates. While intrahepatic bile duct proliferation is universal at diagnosis, bile duct paucity develops later. We hypothesized that polarized T helper lymphocyte responses orchestrate progression of intrahepatic biliary injury in this disease. IL-17A-GFP, CD11c/DTR and IL17RA-/- mice were used to examine T-lymphocyte polarization, inflammatory leukocyte recruitment and biliary injury in rhesus-rotavirus induced biliary atresia...

BACKGROUND: Despite the existence of effective prevention and treatment interventions, hepatitis B virus (HBV) infection continues to cause nearly 1 million deaths each year. WHO aspires to global control and elimination of HBV infection. We aimed to evaluate the potential impact of public health interventions against HBV, propose targets for reducing incidence and mortality, and identify the key developments required to achieve them. METHODS: We developed a simulation model of the global HBV epidemic, incorporating data on the natural history of HBV, prevalence, mortality, vaccine coverage, treatment dynamics, and demographics...
