The Detection of Rotavirus Antigenemia by Immunochromatographic Kits: a Case Series
Insights
Immunochromatographic kits effectively detected rotavirus antigen in pediatric patients with severe diarrhea. One kit showed sensitivity comparable to enzyme immunoassay, offering a rapid diagnostic alternative for rotavirus infection.
Area of Science:
- Pediatric Infectious Diseases
- Virology
- Immunology
Background:
- Acute gastroenteritis is a leading cause of childhood illness and mortality globally.
- Rotaviruses (RVs) are a primary viral agent of acute gastroenteritis in young children, particularly in Asia and Africa.
- Severe diarrhea and dehydration are significant complications in affected children.
Purpose of the Study:
- To evaluate the efficacy of immunochromatographic (IC) kits for detecting rotavirus antigen in pediatric patient sera.
- To compare the performance of IC kits with enzyme immunoassay (EIA) for rotavirus diagnosis.
- To assess the presence and concentration of anti-rotavirus antibodies (IgG, IgA, IgM) in patient sera.
Main Methods:
- Sera from four unvaccinated pediatric patients (4-6 years) with severe diarrhea were tested using three different IC kits.
- Rotavirus antigen detection was performed using IC kits and confirmed by pretreatment with anti-VP6 rotavirus mouse monoclonal antibody.
- Anti-rotavirus IgG, IgA, and IgM antibody levels were quantified using enzyme immunoassay (EIA).
Main Results:
- All three IC kits detected rotavirus antigen in patient sera, with varying line intensities.
- Pretreatment with anti-VP6 antibody confirmed the presence of rotavirus VP6 protein antigen in all tested sera.
- EIA revealed the presence of IgG, IgA, and IgM antibodies against rotavirus in all patient sera at diverse concentrations.
Conclusions:
- One IC kit demonstrated sensitivity comparable to EIA for rotavirus antigen detection.
- This specific IC kit presents a viable alternative for the rapid screening and diagnosis of rotavirus infections in children.
- Early and accurate diagnosis of rotavirus is crucial for timely management of severe gastroenteritis.
Background:
Acute gastroenteritis is the most common cause of illness and death in infants and young children worldwide. Rotaviruses (RVs) are the major viruses that cause acute gastroenteritis in young children, especially in developing countries in Asia and Africa.
Methods:
The presence of rotavirus antigens in sera of four unvaccinated pediatric patients, aged between 4 and 6 years with severe diarrhea and dehydration, were detected by using three immunochromatographic (IC) kits. In addition, the presence of anti-rotavirus IgG, IgA, and IgM antibodies and their concentrations in patient sera were also determined by enzyme immunoassay (EIA).
Results:
All three kits could detect rotavirus antigen in patient sera with different intensity of the test lines. When patient sera were pretreated with anti-VP6 rotavirus mouse monoclonal antibody prior to testing, the rotavirus positive test lines disappeared, suggesting that all patient sera contained VP6 protein antigen of rotavirus. Assessment of antibody concentration in these patient sera revealed that all patient sera contained IgG, IgA, and IgM antibodies against rotavirus antigen at different concentrations.
Conclusions:
The sensitivity of rotavirus protein detection in the patient sera of one IC kit brand was comparable to those of the EIA, suggesting this IC kit could be an alternative screening method for rapid diagnosis of rotavirus infection.
