An air biopsy chip will help diagnose pneumonia.

The staff of the Department of Hospital Therapy at the Institute of Motherhood and Childhood of Pirogov University, together with scientists from the Chemical Faculty of Moscow State University, have developed a chip designed to detect the smallest concentrations of hydrogen peroxide in the exhalation of patients. This compound often indicates the development of lung diseases.

This diagnostic method is called an "air biopsy." It can give doctors more information about the patient's condition, so they can choose an individual therapy and monitor its effectiveness.

"Hydrogen peroxide is one of the markers of oxidative stress and allows us to determine the state of reactive oxygen species and antioxidant protection. Oxidative stress occurs in diseases such as pneumonia, exacerbation of chronic obstructive pulmonary disease, pulmonary embolism, kidney syndrome, lung cancer, and other pathologies. The chip allows, of course, to build a different treatment algorithm. That is, prescribe drugs that actively affect oxidative stress," said Alexander Chuchalin, head of the Department of Hospital Therapy at the Institute of Motherhood and Childhood at Pirogov University.
