BACKGROUND: A comprehensive evaluation of associations between the susceptibility to norovirus infections and histo-blood group antigens is not available in the Taiwanese population, in which the non-secretor phenotype is absent. METHODS: A 1:1 matched case-control study was conducted in northern Taiwan from February, 2013 to December, 2014 when an epidemic of norovirus infection occurred. Cases were children < 18 years old who were hospitalized because of diarrhea and were found to have laboratory-confirmed norovirus infections...

Human noroviruses are the primary cause of epidemic and sporadic acute gastroenteritis. The worldwide high morbidity and mortality associated with norovirus infections, particularly among the elderly, immunocompromised patients and children, constitute a serious public health concern. There are currently no approved human vaccines or norovirus-specific small-molecule therapeutics or prophylactics. Norovirus 3CL protease has recently emerged as a potential therapeutic target for the development of anti-norovirus agents...

BACKGROUND: Rotaviruses can cause life-threatening health disorders, such as severe dehydrating gastroenteritis and diarrhea in children. Vaccination is the main preventive strategy to reduce rotavirus diarrhea and the severity of episodes, but vaccines are not fully effective and new episodes may occur, even in vaccinated children. The WHO recommends oral rehydration therapy and zinc supplementation for rotavirus-induced diarrhea management. There is little preclinical evidence to support the use of phytotherapeutics in the management of rotaviral infections...

Genotype G3P[8] of rotavirus A (RVA) is detected worldwide, usually associated with Wa-like constellation and exhibiting a long RNA migration pattern. More recently, a novel intergenogroup, G3P[8] reassortant variant with a short electropherotype has emerged in Asia, Oceania and Europe, denoting an overall potential of unusual rotavirus strains. During a RVA surveillance in Brazil, G3P[8] strains were found displaying a short electropherotype pattern, which had not been detected before in this region. This study aims to characterize the complete genomes of 10 G3P[8] strains detected in Northern region of Brazil...

Abdominal pain and distention in children are commonly encountered problems in the pediatric emergency room. The majority of complaints are found to be due to benign entities such as gastroenteritis and constipation. What confounds these diagnoses is that young children often deliver a challenging and unreliable exam. Thus, it often becomes exceedingly problematic to differentiate these benign conditions from surgical conditions requiring prompt attention including small or large bowel obstruction, volvulus, and appendicitis...

As a leading cause of severe diarrhea in children, the pathogenic role of rotavirus in adults has been underestimated for a long time. A hospital-based prospective clinical and molecular epidemiologic study of rotavirus infections in adults was performed between April 2014 and March 2015 in Shanghai, China. Overall, rotavirus was detected in 48 of 441 (10.9%) specimens with prevalence peaking in December (33.3%) and January (27.9%), whereas bacteria were identified in 45 of 846 (5.3%) samples (p<0.01). The rotavirus winter-spring seasonality (November-March) contrasts with the marked summer-fall seasonality (April-October) of bacterial pathogens (p<0...

The use of antiemetics for vomiting in acute gastroenteritis in children is still a matter of debate. We conducted a double-blind randomized trial to evaluate whether a single oral dose of ondansetron vs domperidone or placebo improves outcomes in children with gastroenteritis. After failure of initial oral rehydration administration, children aged 1-6 years admitted for gastroenteritis to the pediatric emergency departments of 15 hospitals in Italy were randomized to receive one oral dose of ondansetron (0...

Rotavirus A (RVA) strains, a leading cause of severe gastroenteritis in children worldwide, commonly possess the Wa or DS-1 genotype constellations. During a hospital-based study conducted in Hanoi, Vietnam, in the 2012-2013 rotavirus season, G1P[8] strains with a virtually identical short RNA migration pattern were detected in 20 (14%) of 141 rotavirus-positive samples. Two representatives of these strains were shown by whole-genome sequencing to be double-gene reassortants possessing the genotype constellation of G1-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2...

BACKGROUND: Rotaviruses (RV) are the leading cause of gastroenteritis in children less than five years of age worldwide. Rotarix®, a live attenuated monovalent vaccine containing a RV strain of G1P[8] specificity has been included in the childhood immunisation schedule from June 2013 in Scotland. This study aimed to characterise the prevalent RV strains in Scotland before and after the introduction of the RV vaccine. METHODS: RV positive faecal samples from Scottish virology laboratories covering the years 2012-2015 were genotyped...

: Hyperinsulinaemic hypoglycaemia (HH), which causes persistent neonatal hypoglycaemia, can result in neurological damage and it's management is challenging. Diazoxide is the first-line treatment, albeit not all patients will fully respond to it, as episodes of hypoglycaemia may persist and it entails unpleasant adverse effects. Sirolimus, an mTOR inhibitor, has reportedly been successful in treating children with severe diffuse HH, thus obviating the need for pancreatectomy. We report a girl with HH, with a novel heterozygous ABCC8 gene missense mutation (c...

Probiotics have been recognized as vaccine adjuvants and therapeutic agents to treat acute gastroenteritis in children. We previously showed that rice bran (RB) reduced human rotavirus diarrhea in gnotobiotic pigs. Human noroviruses (HuNoVs) are the major pathogens causing non-bacterial acute gastroenteritis worldwide. In this study, Lactobacillus rhamnosus GG (LGG) and Escherichia coli Nissle 1917 (EcN) were first screened for their ability to bind HuNoV P particles and virions derived from clinical samples containing HuNoV genotype GII...

The main purpose of this study was to investigate bifidobacteria flora in fecal samples from children with rotavirus infection and determine the significance of their selected probiotic properties for improvement of health status. Enzyme-linked immunosorbent assay was used to identify rotavirus antigen in fecal samples from 94 patients with gastroenteritis and from 30 without gastroenteritis. Bifidobacteria were identified by selective media, gram reaction, colony morphology, fructose-6-phosphate phosphoketolase enzyme activity and classical identification tests...

BACKGROUND: Rotavirus nonstructural protein 4 (NSP4) has been suggested as a pathogen of rotavirus-associated seizures. We investigated pre-existing serum antibodies against NSP4 and VP6 (the most highly immunogenic rotavirus protein) in patients with rotavirus gastroenteritis and its correlation with the occurrence of seizures. METHODS: With an enzyme-linked immunosorbent assay, IgG and IgA titers against NSP4 (genotype [A] and [B]) and VP6 were measured in acute-phase sera of 202 children aged 0...

BACKGROUND: Rotavirus infection causes considerable disease burden of acute gastroenteritis (AGE) hospitalization and death among children less than 5 years in China. Although two rotavirus vaccines (Rotarix and RotaTeq) have been licensed in more than 100 countries in the world, the Lanzhou Lamb rotavirus vaccine (LLR) is the only vaccine licensed in China. This study aims to forecast the potential impacts of the two international vaccines compared to domestic LLR. METHODS: An economic evaluation was performed using a Markov simulation model...

Visceral hypersensitivity (VH) and abnormal coping are common in children with functional abdominal pain disorders (FAPDs). Thus, it would be expected that children with VH would report more pain if their gut is acutely inflamed. Aims- Compare clinical symptoms and somatization of children with and without FAPDs at time of an episode of acute gastroenteritis (AGE). Seventy children with AGE and their parents completed the Rome III Diagnostic Questionnaire for Pediatric Functional GI Disorders and the Children's Somatization Inventory...
