Objective: Mean platelet volume (MPV) is a determinant of inflammation. The aim of the present study was to investigate the MPV levels in children with rotavirus gastroenteritis and to evaluate the possible relationship between MPV and severity of gastroenteritis.
Methods: Children diagnosed with acute rotavirus gastroenteritis and healthy controls were enrolled in this study. Patients were classified into three disease severity groups based on their Vesikari score (<7 mild, 7-10 moderate and >11 severe). Rotavirus was determined in fresh stool samples using ELISA test. Leukocyte and platelet counts, MPV and C-reactive protein (CRP) levels were assessed for all children.
Findings: A total of 151 patients with rotavirus gastroenteritis (mean age 2.41± 0.14 years) and 80 healthy controls (mean age 2.63±0.22 years, P=0.129) were enrolled. MPV levels of children with rotavirus gastroenteritis were significantly lower than those of healthy peers (7.48±0.04 vs 7.79±0.07 fl, P=0.000). MPV levels were not significantly different among three gastroenteritis groups. Gastroenteritis score was positively correlated with leukocyte (r=0.670, P<0.01) and platelet count (r=0.159, P<0.05) and CRP level (r=0.256, P<0.01) in patients group. MPV was inversely correlated with platelet count. There was no significant correlation between MPV and gastroenteritis score.
Conclusion: MPV levels were significantly lower in children with rotavirus gastroenteritis compared to controls. MPV can be used as a negative acute phase reactant in children with rotavirus gastroenteritis.

In 2020, severe diarrhea occurred in four-month-old fattening pigs from nine farms in Shandong Province, China. Fecal samples were collected from diseased pigs and tested by PCR for the presence of mammalian orthoreovirus (MRV), porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV), porcine rotavirus A (PoRVA), transmissible gastroenteritis virus (TGEV), porcine kobuvirus (PKV), and pseudorabies virus (PRV). The viral RNA of MRV and PEDV was detected in the fecal samples.

Background: Rotavirus (RV) and Adenovirus (AdV) gastroenteritis affect children worldwide. The sensitivity and specificity of the AMP Rapid Test ROTA/ADENOVIRUS [AMP-RA] for the detection of RV and AdV were compared against qPCR Allplex™ GI-Virus Assay [Allplex-GI].
Methods: A cross-sectional hospital-based surveillance study was conducted using stool samples from 1,148 patients under the age of five years between July 2023 and May 2024 with gastroenteritis.

Background/objectives: Rotavirus (RV) is the primary cause of gastroenteritis in children worldwide, contributing significantly to morbidity and mortality, particularly among children under five years of age. The introduction of Rotavirus vaccines (RVV) has markedly reduced RV-related childhood deaths, especially in Europe, where substantial reductions in hospitalizations and disease prevalence have been observed. Despite these advances, RVV uptake in Italy remains below the desired targets, with notable regional disparities.

Aim: To develop and internally validate a new severity score to more accurately assess the clinical severity forms of acute gastroenteritis (AGE) in children from birth to age 5 years.
Methods: We included children consulting for AGE in the emergency department of the University Hospital of Nantes (March 2017-June 2019). We developed and evaluated a new predictive score (GASTROVIM score) using the classification and regression trees.

Background: Rotavirus (RV), norovirus (NoV), human enteric adenovirus (HAdV), human astrovirus (HAstV), and sapovirus (SaV) are important viral causes of acute gastroenteritis (AGE) in children. However, limited information is available regarding AGE in Yunnan, Southwest China.
Methods: To investigate the prevalence of group A rotavirus (RVA), norovirus genogroups I (GI) and II (GII), and HAdV, HAstV, and SaV in children aged <5 years hospitalized with AGE between 2020 and 2022.
