Brief summary

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.

Detailed description

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 four (4) medical assessment visits at CHUM, over a period of time of four (4) weeks, and answer to one (1) phone call. This study will include five (5) periods : 1. Determination of eligibility period (Day 0) 2. Saline irrigation period (Day 0 to Day 7) 3. Elimination of saline period (Day 8 to Day 14) 4. Probiotic treatment period (Day 15 to Day 21) 5. Telephone follow-up period (Day 22 to Day 28)

Design outcomes

Primary

MeasureTime frameDescription
Change in sense of smell using the University of Pennsylvania smell identification test (UPSIT-40)Change from baseline sense of smell at Day 7and Day 14A 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.

Secondary

MeasureTime frameDescription
Change in sino-nasal symptomatology using questionnaireChange from baseline sino-nasal symptomatology at Day 7, Day 14 and Day 21This 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)Change from baseline Eustachian tube symptomatology at Day 7, Day 14 and Day 21Using a questionnaire of Eustachian Tube Dysfunction (ETDQ-7).
Change in ear examinationChange from baseline ear examination at Day 7 and Day 14
Change in anterior rhinoscopyChange from baseline anterior rhinoscopy at Day 7 and Day 14

Other

MeasureTime frameDescription
Change in microbiome compositionChange from baseline microbiome composition at Day 7 and Day 14Evaluation of the difference in the percentage of the bacterial population before and after treatment.
