A simple and inexpensive saline solution could slow the spread of COVID-19 in the infected person. As well as reducing the chances of a more severe inflammation, according to a preliminary study carried out in Brazil and released this Thursday, September 9.
ON THE STUDY OF SALT AGAINST COVID-19
Investigations indicated that a 1.5% sodium chloride (salt) solution prevented the replication of the coronavirus by 100% in kidney cells of a monkey.
While the same product with a concentration of 1.1% inhibited the duplication of the virus by 88%. In tests performed with infected human lung epithelial cells.
If efficacy is demonstrated in clinical trials, the finding may contribute to the development of new prophylactic strategies or even treatments to combat the disease. COVID-19.
The finding does not represent full protection against infection
The study was published in the journal “ACS Pharmacology & Translational Science.” It was advanced by scientists from the University of Sao Paulo, with funding from the Foundation for Research Support in the State of São Paulo (Fapesp).
According to the researchers, although the evidence suggests that the use of saline inhibits the replication of the virus. The finding does not represent a total protection against infection, much less a cure for the disease.
Already used as a prophylaxis for other respiratory diseases
“This is a very simple and inexpensive measure, already used as a prophylaxis of other respiratory diseases and that could minimize the severity of COVID-19 by reducing the viral load.” This was pointed out by Cristiane Guzzo, one of the researchers, quoted in a statement.
The “hypertonic sodium chloride” solution has been used as an additional preventative measure for flu, bronchiolitis, rhinitis, sinusitis, and a variety of respiratory problems.
According to the expert, the analyzed product could be incorporated into the current security protocols against SARS-CoV-2. This, without replacing the use of face masks, social distancing or the need for vaccination.
Salt may enter clinical trials
The researchers suggest testing two types of saline use in clinical trials, depending on the need.
The first is to use it in the form of a nasal spray, for prevention in the respiratory tract. Which are the gateway to the coronavirus, and which could be used by people who are more likely to be infected with the virus.
Nebulisations are the second method recommended by the experts, since with them the serum is administered directly to the lung.
