Electronic nose can detect lung transplantation failure with 86% accuracy

According to a study published at the "virtual" European Respiratory Society International Conference, when lung transplantation begins to fail, the electronic "nose" can be detected with 86% accuracy

 Ms.

"About 50% of lung transplant patients are diagnosed with chronic allograft dysfunction or chronic rejection within 5 years after transplantation

 "Once chronic rejection is confirmed, patients can live for an average of 1 to 5 years

Currently, it may take several months to diagnose CLAD

The electronic nose [1] is a small device that contains sensors to detect chemical substances volatile organic compounds (volatile), which appear in about one percent of the exhaled breath, depending on the metabolic process, which occurs in the entire body or part of the Areas, such as lungs

Ms.

The patients were between 35-73 years old, 47% were male, and the median (average) time after lung transplantation was 3.

Ms.

The patients in the study continued to provide eNose measurements every time they visited the outpatient department so that the researchers could track their progress

There are two types of chronic rejection: bronchitis obliterans syndrome (BOS) and restricted allograft syndrome (RAS)

"We hope that our further research can reveal whether the eNose technology can distinguish between BOS and RAS

Stefano Elia was not involved in the study.

The electronic nose used in the study is SpiroNose produced by Breathomix
