Clinical Application of Phage Immunoprecipitation Sequencing to Diagnose Enterovirus D68 as the Underlying Etiology in a Case of Guillain-Barré Syndrome
To demonstrate the utility of phage immunoprecipitation sequencing (PhIP-Seq) in supporting the etiological diagnosis of Guillain-Barré syndrome (GBS) linked to enterovirus D68 (EV-D68) infection, particularly in cases where traditional diagnostic methods are inconclusive.
Key Findings:
A 6-year-old female developed GBS following a confirmed EV-D68 respiratory infection, underscoring the need for vigilant monitoring of such cases.
PhIP-Seq identified antibodies against enterovirus D in the patient's CSF, supporting the diagnosis of GBS linked to EV-D68 and suggesting a novel diagnostic pathway.
Interpretation:
The findings suggest that PhIP-Seq can effectively link GBS cases to prior enterovirus infections, enhancing diagnostic capabilities when traditional methods fail, and potentially guiding treatment decisions.
Limitations:
The study is based on a single case report, limiting generalizability and necessitating further research.
Potential variability in antibody response timing and concentration may affect results, indicating a need for standardized protocols.
Conclusion:
PhIP-Seq is a promising tool for diagnosing GBS associated with viral infections, particularly when conventional testing yields inconclusive results.
