简要总结
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.
详细描述
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 :
- Determination of eligibility period (Day 0)
- Saline irrigation period (Day 0 to Day 7)
- Elimination of saline period (Day 8 to Day 14)
- Probiotic treatment period (Day 15 to Day 21)
- Telephone follow-up period (Day 22 to Day 28)

结局指标
主要结局
Change in sense of smell using the "University of Pennsylvania smell identification test (UPSIT-40)"
时间窗: 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.
次要结局
- Change in ear examination(Change from baseline ear examination at Day 7 and Day 14)
- Change in sino-nasal symptomatology using questionnaire(Change from baseline sino-nasal symptomatology at Day 7, Day 14 and Day 21)
- 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 21)
- Change in anterior rhinoscopy(Change from baseline anterior rhinoscopy at Day 7 and Day 14)
