Safety of Intranasal Irrigation Probiotics in Healthy Volunteers
Chronic rhinosinusitis (CRS) is one of the most common chronic diseases, affecting the quality of life of patients who suffer. Despite medical and surgical treatments available, there are a significant number of people suffering from CRS refractory to these standard treatments.
A preliminary clinical trial conducted at CHUM Hôtel-Dieu, has allowed us to evaluate the therapeutic potential of intranasal irrigation of probiotics in patients with CRS. This treatment administered twice daily for 14 days was well tolerated and resulted in improved chronic rhinosinusitis symptoms.
Prior to deployment on a larger scale, the safety of this therapy must be confirmed in a healthy population, free of sinus disease. Therefore, this study aims to assess the safety of the use of probiotic intranasal irrigation in healthy volunteers.

- Change in sense of smell using the "University of Pennsylvania smell identification test (UPSIT-40)" [ Time Frame: Change from baseline sense of smell at Day 7and Day 14 ]A smell test will be conducted using "scratch and sniff fragrance strips" (UPSIT-40), where 40 odors are presented. The participant must choose one of four choices for each odor, even if she/he is unable to identify the smell.
- Change in sino-nasal symptomatology using questionnaire [ Time Frame: Change from baseline sino-nasal symptomatology at Day 7, Day 14 and Day 21 ]This questionnaire evaluates 5 items (nasal congestion, facial pain, headache, need to blow nose, post-nasal drip) on 0-3 scale (0= none; 1=mild; 2=moderate; 3= severe).
- Change in Eustachian tube symptomatology using a questionnaire of Eustachian Tube Dysfunction (ETDQ-7) [ Time Frame: Change from baseline Eustachian tube symptomatology at Day 7, Day 14 and Day 21 ]Using a questionnaire of Eustachian Tube Dysfunction (ETDQ-7).
- Change in ear examination [ Time Frame: Change from baseline ear examination at Day 7 and Day 14 ]
- Change in anterior rhinoscopy [ Time Frame: Change from baseline anterior rhinoscopy at Day 7 and Day 14 ]
- Change in microbiome composition [ Time Frame: Change from baseline microbiome composition at Day 7 and Day 14 ]Evaluation of the difference in the percentage of the bacterial population before and after treatment.

If the participant (healthy volunteer) agrees to participate in the study, and after signing the information consent form, her/his participation in this project will consist to receive the experimental treatment of probiotics, to come to three (3) medical assessment visits at CHUM Hôtel-Dieu, over a period of time of three (3) weeks, and answer to one (1) phone call.
This study will include the following four (4) periods :
- determination of eligibility period - Day 0
- saline irrigation period (for 7 days) - between Day 0 and Day 7
- probiotic treatment period ( for 7 days) - between Day 7 and Day 14
- telephone follow-up period - Day 21
