A cytokine storm may occur in patients with bronchitis or some strains of influenza. “We saw that in the flu pandemic that happened at the end of World War I and we’re still seeing it today.” A Normal Immune Response. Just like any storm, a cytokine storm builds if left unchecked. More pro-inflammatory cytokines lead to even more inflammation, causing a domino effect, or the perfect storm… of pain. Physicians in Wuhan, in a study of 29 patients, reported that higher levels of the cytokines IL-2R and IL-6 were found in more severe Covid-19 infections. At all times, white blood cells circulate in the bloodstream and are the first to sense if a virus or bacteria has infiltrated the body. But during a cytokine storm, your body releases too many of these proteins into your blood too quickly, according to the National Cancer Institute (NCI). The researchers found that patients in a cytokine storm had a pro-inflammatory status and elevated levels of enzymes that suggested they had significant, widespread tissue damage. A cytokine storm is an overproduction of immune cells and their activating compounds—cytokines—which, in something like a flu infection, is often associated with a surge of activated immune cells into the lungs. To explain this more simply, cytokine storm occurs when the body is flooded with the release of too many cytokines in a short period of time. Immediately, other immune cells, including T-cells and macrophages, are sent to attack the infection. Read on to know what is a cytokine storm, what happens in the body during a cytokine storm, what are the different types of cytokines, cytokine storm in COVID-19 and treatment of cytokine storm A cytokine storm — aka cytokine release syndrome, macrophage activation syndrome, hemophagocytic lymphohistiocytosis — is the result of an immune system gone wild. The inflammation is generally accompanied by pain, redness, fever, and edema and often results in tissue damage. So, what is a cytokine storm? The first hints that severe COVID-19 cases included a cytokine storm came out of Chinese hospitals near the outbreak’s epicenter. Cytokine storm, also called cytokine release syndrome or hypercytokinemia, is a condition that consists of an immune reaction involving a positive feedback loop between immune cells and cytokines. https://knowablemagazine.org/article/health-disease/2020/what-cytokine-storm What is a cytokine storm? “A cytokine storm is generally what leads to otherwise healthy young people dying of the flu,” says David Martin, Senior Medical Director at Pfizer. Patients who met the criteria also had longer hospital stays and were at an increased risk of death from COVID-19. Cytokine storm in COVID-19. Cytokine storm is an overreaction of the immune system to an infection, injury or other insults. A cytokine storm begins at a local site (typically an organ or tissue) and then spreads throughout your body via systemic circulation. Killer cells are often defective, resulting in increased production of inflammatory proteins that can lead to organ failure and death. Cytokine overproduction may keep your body in a constant state of inflammation which leads to even more inflammation. While a …
