A twenty-year-old woman underwent a lung transplant in the American city of Chicago after the "Covid-19" disease caused by the emerging coronavirus "SARS Cove 2" caused permanent damage to her lungs, according to the hospital that saved her.

And "Northwestern Hospital" in Chicago said in a statement Thursday that "subjecting her to a lung transplant was her only chance to survive."

This operation appears to be the first of its kind in the United States and not in the world, as Chinese doctors performed a lung transplant last March.

The hospital pointed out that the patient is a young woman of Latin American origin who was in good health, but she was seriously ill with the emerging corona virus to the point that she was admitted for six weeks to intensive care, where she was kept on the artificial respirator and attached to a special machine that replaces the heart and lungs automatically.

Dangerous situation

This patient "stayed for days with the most serious injury in the resuscitation department for Covid-19 patients and probably the entire hospital," said Piet Malcene, a pulmonary specialist in Northwestern Medicine.

However, it was necessary to wait for the implant to be completed before its result in the examination of Corona became negative.

"How can a healthy woman at the age of twenty get into this situation? We have to learn a lot about Covid-19," said lung specialist Radom Tomic.

Immune cells

The question posed by Tomic highlights that scientists have a lot to learn about the course of the emerging Corona virus, which has been the subject of a recent study of 40 patients, in which German scientists have found that two types of immune cells can predict the course of the Corona virus in the body. Thus, these scholars confirm the results of another Chinese study conducted earlier.

German scientists confirmed the result of an earlier study on 40 people infected with the emerging coronavirus in Wuhan, China, which is to predict the path the virus will take in any patient with the help of two types of immune cells in the blood.

The results of that study were confirmed by many patients in Germany, said Olf Dettmeter, director of the Institute of Virology at the University Hospital Essen, Germany and vice-president of the German Society for Virology.

One of the two types of these immune cells is called killer T cells that contain surface markers called "clusters of differentiation" (CD8). They kill the cells infected with the virus, and then break the virus’s growth in the body.

"When patients have only a few of these cells, they face a great risk of developing severe symptoms such as pneumonia or blood clotting disorders," the German scientist said.

The quality of the other cells is neutralized, and from them the German scientist adds, "These cells are present primarily to deal with bacteria. But they can also suppress T cells in their function." Therefore, only a small number of killer cells were found in blood samples containing many These neutral cells.

The results of this study provide an additional explanation as to why people with chronic diseases or previously experiencing severe health crises are prey to Covid-19.

Previous health problems

"Patients who have had previous health problems have a decrease in the number of T cells. This applies to patients who have received human organs and (during the transplant) received medicines to suppress rejection reactions. These, for example, were affected by Special".

And the expert adds that cancer patients who are receiving chemotherapy, or elderly people who have a decline in age-related T cells, or obese patients, it is very likely that serious symptoms will appear on their lives.

And for obese people in particular, the German expert says, "We know that overweight people have weaker and less T cells."
