One of many weirder signs of COVID-19 (hair loss and Covid penis apart) is the illness’s capability to remove your sense of odor. Fittingly, there is a bizarre technique to get that sense of odor again: having a giant sniff of your personal blood.
Round one in 5 individuals who get COVID-19 report some stage of lack of odor, about eight weeks after being infected. Scent coaching – sniffing robust smells a number of occasions a day over the course of a number of months – has proven some effectiveness in restoring smell. Nevertheless, in accordance with otolaryngologist David Rosen of Thomas Jefferson College, even the best odor retraining therapies solely restore sufferers’ sense of odor by around 35 percent.
For one more potential remedy – being studied in the meanwhile – it is time to snort your personal platelets.
Platelet-rich plasma remedy, Rosen explains to Drug Discovery News, has been round for about 40 years. The remedy works by encouraging nerves within the olfactory system to heal themselves.
“If a nerve that goes to the finger and permits it to maneuver will get lower, it most likely received’t work once more if we put it again collectively as a result of these nerves can’t regenerate very properly,” Rosen advised Drug Discovery Information.
“However we will regenerate olfactory neurons by jumpstarting the physique’s personal capability to restore itself with plasma. Platelets have lots of progress elements that inform the physique, ‘okay, begin making stem cells and begin differentiating these into neurons.’ Broken neural tissue is just not straightforward to restore, however on this occasion, we get away with it due to the neuroplasticity already on this system.”
The remedy takes little widgets created from cellulose and soaks them within the affected person’s personal plasma. The widget is then packed into the again of the nostril, as excessive as attainable, the place it’ll reside for a while. Within the first minute after this, 80 p.c of the platelet-rich plasma is absorbed, whereas the remainder will get slurped up over the subsequent few days.
Rosen is having success with the remedy of COVID-19 sufferers in a pilot research involving a number of dozen sufferers. Nevertheless, he’s conscious he wants extra information to again up the outcomes he is seen to date, evaluating the remedy with those that have undergone odor retraining. His workforce will quickly start a placebo-controlled research, and hopes to undergo a part II trial quickly after that.
“I noticed a affected person yesterday who had solely acquired two remedies to date, and he or she advised me that grass smelled like grass to her once more and chocolate tasted like chocolate,” he added. “I’m excited to see individuals getting again to their regular lives.”
