Current Primary Outcome Measures  ICMJE
 (submitted: October 12, 2016)
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.
Original Primary Outcome Measures  ICMJE Same as current
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: October 12, 2016)
  • 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 ]

Current Other Pre-specified Outcome Measures
 (submitted: October 12, 2016)
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.

Descriptive Information
Brief Title  ICMJE Safety of Intranasal Irrigation Probiotics in Healthy Volunteers
Official Title  ICMJE Safety of Intranasal Irrigation Probiotics in Healthy Volunteers
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)
