The next is a abstract of some current research on COVID-19. They embrace analysis that warrants additional research to corroborate the findings and that has but to be licensed by peer assessment.
HIV medication could curb COVID-19 danger
Sure medication used to deal with HIV could have a job in stopping SARS-CoV-2 infections, in line with preliminary information that will assist clarify why folks dwelling with the situation haven’t seemed to be at increased danger for severe COVID-19 regardless of being usually extra susceptible to infections.
Medical doctors in France studied greater than 500 folks with HIV, a 3rd of whom had been receiving long-term therapy with protease inhibitor medication as a part of their antiviral remedy.
Over the course of a yr, SARS-CoV-2 infections had been recognized in 12% of members taking protease inhibitors and 22% of these not receiving these medication.
4 sufferers within the non-protease-inhibitor group had been admitted to hospital with COVID-19.
After accounting for different danger elements, people taking protease inhibitors had been 70% much less prone to grow to be contaminated with SARS-CoV-2 than sufferers who weren’t taking these medication, in line with information scheduled for presentation on the European Congress of Medical Microbiology & Infectious Ailments.
Some new remedies for COVID-19 use protease inhibitors, which block the virus from multiplying.
“Protease inhibitor medication have lengthy historical past of use, a great security profile, and are usually properly tolerated,” Dr. Steve Nguala from the Intercommunal Hospital Middle of Villeneuve-Saint-Georges, stated in an announcement.
They’ve the potential “to stop the unfold of infections and mutation of future variants,” he stated, including that bigger research are wanted to verify the findings.
COVID-19 and flu make for a harmful combo
Having COVID-19 and influenza on the identical time places hospitalized adults at a lot better danger of crucial sickness and demise in comparison with having COVID-19 with out the flu, researchers reported on Friday in The Lancet.
Sufferers with SARS-CoV-2/influenza coinfections had been greater than 4 occasions as prone to require machines to assist them breath and a pair of.4 occasions as prone to die in comparison with sufferers who solely had COVID-19, in line with a research of almost 7,000 hospitalized sufferers with COVID-19, together with 227 who additionally had the flu. Dr. Kenneth Baillie of the College of Edinburgh, who led the research, stated the mix of the 2 viruses is especially harmful.
“We anticipate that COVID-19 will flow into with flu, growing the possibility of co-infections. That’s the reason we should always change our testing technique for COVID-19 sufferers in hospital and check for flu far more broadly,” Baillie stated in an announcement.
“The vaccines that shield in opposition to COVID-19 and flu are totally different,” added Dr. Peter Openshaw of Imperial Faculty London, “and folks want each.”
Experimental COVID drug could also be preventive and therapeutic
An experimental drug designed to be sprayed into the nostril has proven the potential to each forestall an infection and deal with COVID-19, at the very least for some variants of the coronavirus, in line with a research in mice.
The drug, referred to as N-0385, inhibited entry of the virus into cells within the mice when administered earlier than an infection.
When given as much as 12 hours after an infection, it prevented the mice from turning into critically unwell, researchers from Cornell College in Ithaca, New York reported on Monday in Nature. N-0385 is a small molecule that inhibits an enzyme referred to as TMPRSS2.
Some variants of the coronavirus – however not Omicron – use TMPRSS2 and the ACE2 protein on cell surfaces to fuse themselves to the cell membrane and inject their genetic materials inside.
N-0385, which might be given in only some day by day doses, “is less complicated and cheaper to mass produce than different kinds of COVID-19 remedies, akin to monoclonal antibodies,” research chief Hector Aguilar-Carreno stated in an announcement.
The present research examined the drug in opposition to the unique model of the virus and the Delta variant, however not in opposition to Omicron.
California-based EBVIA Therapeutics Inc stated it’s elevating funds for human trials, drug growth, formulation and mass manufacturing of N-0385.
If medical trials affirm its security and efficacy, giving N-0385 together with different antiviral medication might assist scale back the chance of mutations that enable the virus to withstand therapy, the analysis crew stated.
