Astroviruses
Presentation
- CONCLUSIONS: The present study showed that although HAstV infections occur at low frequency, they are involved in severe pediatric cases of acute gastroenteritis presenting with a high diversity of strains, including the lineages 3c and 4c, which were[ncbi.nlm.nih.gov]
- We have previously described the identification of several sequence fragments with limited sequence identity to known astroviruses in a stool specimen obtained from a child with acute diarrhea, suggesting that a novel virus was present.[ncbi.nlm.nih.gov]
- The group of children between 2 and 5 years old presented the higher percentage of infections.[ncbi.nlm.nih.gov]
- RESULTS: The detection limit of LAMP using in vitro RNA transcripts was 3.6 10 copies·μL ¹, which is as sensitive as the presently used PCR assays.[ncbi.nlm.nih.gov]
- Three weeks after the third fludarabine course he presented with a 5-day-history of watery diarrhoea, nausea and vomiting.[ncbi.nlm.nih.gov]

Burkina Faso
- STUDY DESIGN: Viral nucleic acids were enriched from the feces from 48 cases of unexplained diarrhea from Burkina Faso, sequenced, and compared against all known viral genomes.[ncbi.nlm.nih.gov]

Weight Gain
- CAstV Chicken astrovirus has been associated with runting-stunting syndrome (RSS) in chickens characterized by poor weight gain, lower feed conversion, and mortality resulting in economic losses [ 97 ], and “white chicks” disease associated with increased[mdpi.com]
Gastrointestinal
Regurgitation
- Pathogenesis Clinical signs and pathology Both adult and juvenile cheetahs present with signs of lethargy, partial to complete anorexia, diarrhea and regurgitation over an a short period of time.[awp.eduwikis.co.za]
Cardiovascular
Hypotension
- Despite these interventions, he developed new symptoms of central dyspnea, postural hypotension, nausea, and gradually worsening balance. Repeat neurological assessment confirmed persistent vestibulocochlear dysfunction 6 weeks after symptom onset.[academic.oup.com]
Neurologic
Lethargy
- The initial signs include mild lethargy, and partial anorexia that progress to a watery diarrhea and vomition.[awp.eduwikis.co.za]

Treatment
- Symptomatic treatment was given but since his condition deteriorated, high-dose intravenous immunoglobulin (IvIg) treatment, 0.4 g/kg for four days was initiated.[ncbi.nlm.nih.gov]
- […] of cells (blocking effect), direct viral activity (virucidal effect) and post-treatment of infected cells (reduction of viral yield post-infection).[ncbi.nlm.nih.gov]
- In this work we present several experimental findings that show that human astrovirus (HAstV) RNA encodes a VPg essential for viral infectivity: (i) RNase treatment of RNA purified from astrovirus-infected cells results in a single protein of 13 to 15[ncbi.nlm.nih.gov]
- Large immune aggregates were found after treatment of the faecal specimen with pooled human immunoglobulin.[ncbi.nlm.nih.gov]
- Treatment consisted in symptomatic care and the outcome was favorable.[ncbi.nlm.nih.gov]

- Astrovirus infection might constitute a common etiology of gastroenteritis in patients with hematologic malignancies that have been severely immunocompromised with FAMP or other purine analogues, and therefore should be more systematically investigated[ncbi.nlm.nih.gov]
- Abstract Many diseases with unknown etiology may be caused by unidentified viruses. Sequence-independent amplification revealed a new astrovirus, similar to VA1, in a 4-year-old male diagnosed with celiac disease.[ncbi.nlm.nih.gov]
- In order to provide more insights into the epidemiology of enteric viruses that are not included usually in routine diagnostic tests, cases of childhood sporadic gastroenteritis of unknown etiology requiring hospital admission in Parma, Italy, during[ncbi.nlm.nih.gov]

Epidemiology
- Data on the epidemiology and the response to the outbreak was collected. RESULTS: All samples had a 99% match to human astrovirus type 5.[ncbi.nlm.nih.gov]
