A study from the Hospitals of the University of Geneva (HUG), on Monday 22 November, revealed that some patients with cancer-related pain noticed a decrease, or even disappearance, in pain perception during the acute phase of infection. in Covid-19.
Could infection with the COVID-19 virus cause a decrease or even disappearance of pain? That’s what the resultsStudy of doctors from Geneva University Hospitals (HUG), posted on Monday, November 22.
A Swiss working group, made up of health professionals in palliative medicine, neurology, radiology and pathology, has highlighted an unexpected phenomenon: “A marked, but transient, reduction in pain in three oncological patients with severe Covid-19.”
Their work has been published in Prestigious international scientific journal Pain (“Pain” in English, editor’s note), explains that infection with the virus “It can, perhaps through a malfunction of the nervous system, cause ‘atypical’ symptoms.”
The scientific team examined three patients between the ages of 67 and 84 years, suffering from cancer and severe pain in tumors. These three individuals, who were hospitalized at HUG due to Covid-19 infection, were also resistant to opioid treatment.
“The three patients noticed a reduction, or even disappearance, of their pain, soon after the injury. Recovery from Covid-19 was also associated with a gradual return of pain in one of the patients.Scientists note. At this time, this phenomenon is still unexplained, but the team is making some assumptions.”
One of these hypotheses indicates that infection with a virus or “As a result of the inflammatory storm that could cause Covid-19” It can reach the “island crust”. This part of the cerebral cortex, buried deep in the folds of the cortex, plays a role in various bodily functions, including “Investigation” internal perceptions.
The virus can interfere with the transmission of the nerve message that causes pain or shortness of breath.The University of Geneva Hospitals Study (HUG).
Another hypothesis: “SARS-CoV-2 can cause more dysfunction in the extremities, that is, in the spinal cord. The virus can interfere with the transmission of the nerve message that causes pain or the sensation of shortness of breath.”
“Although further studies are needed to confirm these observations and validate the hypotheses put forward, these observations shed new light on the mechanisms responsible for pain perception that could open new avenues for research and treatment.”, concludes the document.
