Brief summary

Assessment of the improvement of the safety of the swallowing function under 3 natural ingredients known to be agonist of sensory receptors.

Detailed description

The trial will be double-blind, randomized, monocentric, and interventional with a hybrid design. The subjects will be randomized to one of the three parallel active ingredient groups. Products will be compared versus control (Thicken Up Clear - nectar viscosity), which adds a part of cross over within the design. The total sample size is 84 enrolled subjects. Patients will be males and females aged 55+ with mild proven dysphagia.

Interventions

acute exposure to natural ingredient during physiological parameters recording (deglutition or cortical activity)

OTHERlemon extract

acute exposure to natural ingredient during physiological parameters recording (deglutition or cortical activity)

OTHERlemon extract plus eucalyptus extract

acute exposure to natural ingredient during physiological parameters recording (deglutition or cortical activity)

OTHERThicken Up clear: TUC

Design outcomes

Primary

MeasureTime frameDescription
Improvement of the safety of the swallowing function, according to Rosenbek's scaleup to15 min after ingredient ingestionThe maximum PAS score across the different boluses (5, 10 and 20 ml) during nectar series (with and without active ingredient) assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.

Secondary

MeasureTime frameDescription
Swallowing safety-Prevalence of aspirationup to15 min after ingredient ingestionthe prevalence of aspiration in the population according to Rosenbek's PAS (scores of 6-8), assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.
Efficacy of swallowing function-Severity of the amount of oral and pharyngeal residuesup to15 min after ingredient ingestionSeverity of the amount of oral and pharyngeal residues, assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.
Efficacy of swallowing function-Prevalence of subjects with oral and pharyngeal residuesup to15 min after ingredient ingestionPrevalence of subjects with oral and pharyngeal residues, assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.
Efficacy of swallowing function-Time to upper oesophageal sphincter openingup to15 min after ingredient ingestionTime to upper oesophageal sphincter opening, assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.
Swallowing safety-Prevalence of penetrationup to15 min after ingredient ingestionthe prevalence of penetration in the population according to Rosenbek's PAS (scores of 2-5) , assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.
Efficacy of swallowing function-time to laryngeal vestibule closureup to15 min after ingredient ingestiontime to laryngeal vestibule closure, assessed during videofluoroscopic (VF) recording of radio-opaque bolus deglutition.
Modification of brain physiology response to sensory input:up to 20 min after ingredient ingestionAmplitude and latency of the 4 peaks of the pharyngeal sensory evoked potentials (PSEP) on EEG.
Tolerability to the products (gastrointestinal comfort) using a questionnaire, assessed during EEG sessions (V3 and V4) to avoid capturing side effects of the contrast agent (as nausea).ponctually at the end of visits V3 and V4, after the EEG recording lasting about 30 min, during wich the product is ingestedusing questionnaire
