Povidone Iodine Mouthwash, Gargle, and Nasal Spray to Reduce Naso- Pharyngeal Viral Load in Patients With COVID-19

The SARS-CoV-2 coronavirus pandemic is responsible for more than 180,000 deaths worldwide and 20,000 deaths in France. To date, no treatment or vaccine has been successful. Povidone-iodine is an antiseptic suitable for use on the skin and mucosa with potent virucidal activity, particularly against coronaviruses. It is marketed for oro-nasopharyngeal decolonization.

24 patients with positive nasopharyngeal SARS-CoV-2 carriage will be randomized (1:1) in an experimental group (benefiting from povidone iodine decolonization) or a control group. Patients in the experimental group will be asked to gargle with a 1% povidone-iodine solution, spray their nose with the same antiseptic solution, and finally applied 10% povidone-iodine cream in each nostril, all four times a day for five days. Patients will be followed for 7 days to evaluate the efficacy and safety of povidone iodine decolonization.

Treatment and study plan

Povidone-Iodine

Drug

Patients in the experimental group will be asked to gargle with a 1% povidone-iodine solution, spray their nose with the same antiseptic solution, and finally applied 10% povidone-iodine cream in each nostril, all four times a day for five days.

Primary outcomes

  1. Change from baseline naso-pharyngeal viral load quantified by RT-PCR at Day7

    Time frame: Day 7

Secondary outcomes

  1. Delay between inclusion and negativation of SARS-CoV-2 nasopharyngeal carriage

    Time frame: Day0, Day1, Day3, Day5 and Day7

  2. Delay between inclusion and negativation of SARS-CoV-2 nasopharyngeal cell cultures

    Time frame: Day0, Day1, Day3, Day5 and Day7

  3. Thyroid tests at Day0 and Day7

    Time frame: Day0 and Day7

  4. Patient satisfaction at Day7 using a numerical comfort scale, graduated from 0 (any discomfort) to 10 (maximum possible discomfort)

    Time frame: Day7

  5. Daily presence of clinical signs in favour of COVID-19, including respiratory distress using NYHA scale, chest pain, anosmia, agueusia, tiredness, cough, stiffness, nasal congestion, dysphagia and diarrhea

    Time frame: Day0, Day1, Day3, Day5 and Day7

  6. Need for ward or intensive care hospitalization

    Time frame: Day0, Day1, Day3, Day5 and Day7
