The World Health Organization has recommended that people suffering from the symptoms of the virus avoid taking ibuprofen drugs such as Advil. Instead, the organization suggests taking paracetamol, such as Acamol (Tylenol). They studied why the disease pathway in Italy is more serious, finding that most patients took ibuprofen at home. Researchers joined the virus and ibuprofen in the laboratory and came to the conclusion that administering ibuprofen accelerates multiplication of the virus and is related to a more serious course of the disease. They recommend to avoid ibuprofen and to administer paracetamol, aspirin, and equivalent drugs. Consultant Pediatrician in London John Greenwood was quoted as saying: "We have just been sent a medical alert that no one is to use anti-inflammatories (e.g. Ibruprofen, Voltarol, naproxen, and others) for pain or high temperature. Use paracetamol instead. There seems to be a link between severe cases of COVID-19 affecting young people with no underlying illnesses and taking anti-inflammatories. Initial reports started coming from French doctors on Friday. This has been confirmed by infectious diseases consultants here - there are four young people in ICU in Cork who have no underlying illnesses - all were taking anti-inflammatories and there are concerns this has caused a more severe illness." A Lancet article entitled Are patients with hypertension and diabetes mellitus at increased risk for COVID-19 infection? says: "Human pathogenic coronaviruses (severe acute respiratory syndrome coronavirus [SARS-CoV] and SARS-CoV-2) bind to their target cells through angiotensin-converting enzyme 2 (ACE2), which is expressed by epithelial cells of the lung, intestine, kidney, and blood vessels." "The expression of ACE2 is substantially increased in patients with type 1 or type 2 diabetes, who are treated with ACE inhibitors and angiotensin II type-I receptor blockers (ARBs). Hypertension is also treated with ACE inhibitors and ARBs, which results in an upregulation of ACE2.5 ACE2 can also be increased by thiazolidinediones and ibuprofen. Suggest that ACE2 expression is increased in diabetes and treatment with ACE inhibitors and ARBs increases ACE2 expression. Consequently, the increased expression of ACE2 would facilitate infection with COVID-19. "We therefore hypothesize that diabetes and hypertension treatment with ACE2-stimulating drugs increases the risk of developing severe and fatal COVID-19."
