- Brief Summary
The new coronavirus (SARS-CoV-2) causing COVID-19 is an RNA virus coated with a capsid and a peri-capsid crossed by glycoprotein structures. The external proteic structure, which attacks human cells, is a potential target to therapeutic interventions against virus replication in airways.
Since high temperature can cause irreversible denaturation of proteins and loss of SARS CoV and SARS CoV-2 infectivity was obtained after heating at 56 ◦C for 15 and 30 min in liquid environments respectively, we designed a protocol aimed at damaging SARS-CoV-2 capsid through steam inhalation cycles. Although the ominous consequences of COVID 19 infections has directed medical attention toward solidly established medical approaches, the European Pharmacopoeia VI edition also quotes steam inhalations as a procedure to treat of respiratory diseases.
Based on these suggestions we established a quasi-randomized clinical trial enrolling 200 asymptomatic or paucisymptomatic patients in whom rhino-pharyngeal-swab revealed a SARS-CoV-2 infection. The study protocol consisted of exposure of airway mucosae to humidified steam (pH 8 per NaHCO3 and hypertonic 15 g/L NaCl) through steam inhalation for at least 20 min (4 cycles of 5 min) daily, for 10 days.
The objective of the study is to reduce the viral shedding using steam inhalations.

- Primary Outcome Measures
Name Time Method Reduction in viral shedding From date of randomization until the date of first documented negativization from any cause assessed up to 9 months Difference / ratio between the percentage of subjects with negative swab 10 days after enrollment in the treated group and the percentage in the non-treated group.
- Secondary Outcome Measures
Name Time Method Clinical outcome From date of randomization until the date of first documented clinical improvement from any cause assessed up to 9 months" Difference / ratio between the percentage of subjects with residual symptoms after 10 days of enrollment in the treated group and the percentage of subjects with residual symptoms after 10 days of enrollment in the untreated group (only for the subgroup of patients with severe symptoms).
Negativization rate From date of randomization until the date of first documented negativization from any cause assessed up to 9 months Ratio between the incidence of the negativization rate (number of events / total person days) in the treated group and the incidence of the negativization rate in the untreated group.
