Clinical Scorecard: Influenza Screening: Could a Taste-Based Sensor Play a Role?

At a Glance

Key Highlights

• Development of a taste-based sensor that selectively responds to viral neuraminidase.
• Methylated α-linked sensor demonstrated selectivity for viral neuraminidase over bacterial neuraminidase.
• Neuraminidase activity in saliva from influenza-positive patients was sufficient to activate the sensor.
• Cytotoxicity testing showed no reduction in cell viability at concentrations up to 1.0 mM.
• Sensor stability maintained at least 95% integrity for four weeks under typical storage conditions.

Guideline-Based Recommendations

Diagnosis

• Utilize the taste-based sensor for early detection of influenza through neuraminidase activity.

Management

• Consider the sensor as a low-cost, rapid testing option at the point of care.

Monitoring & Follow-up

• Assess neuraminidase levels in saliva to evaluate sensor activation potential.

Risks

• Further assessment needed against patient-reported outcomes to validate clinical utility.

Patient & Prescribing Data

Hospitalized patients with confirmed influenza.

Milligram-level quantities of sensor estimated for effective oral use.

Clinical Best Practices

• Monitor neuraminidase activity in patients to guide sensor use.
• Ensure sensor selectivity is maintained for accurate influenza detection.
