COPD: the University Hospital of Toulouse is looking for ex-smokers for a study

The University Hospital of Toulouse is looking for former smokers with chronic obstructive pulmonary disease (COPD) in an international study from September. It will test a new innovative and non-pharmacological treatment.

Call to former smokers. The University Hospital of Toulouse is currently looking for former tobacco users with chronic obstructive pulmonary disease (COPD) or emphysema. This pulmonary infection, which affects nearly 3 million French people, is characterized by a persistent decline in the flow of inspired gases. According to WHO, the symptoms worsen gradually with shortness of breath even at rest. The disease is often caused by tobacco smoke, due to active or passive smoking and "tends to be under diagnosed and can be life-threatening", warns WHO.

She is currently incurable and the proposed treatments to relieve her symptoms or slow her progression often insufficient. That's why, an American company called Nuvaira has developed a new non-drug process that it wants to test, among others, the pulmonology department of the University Hospital of Toulouse. The international trial will begin in September.

"The principle of this new therapy is to introduce a probe via a video-endoscope through the patient's mouth and to radiofrequency thermolysis (heat destruction) in both lungs." The goal is to destroy approximately 50% of the bronchial nerves that control the contraction of bronchial muscles, abnormal in COPD ", explains the hospital on its website.

Volunteers must have stopped smoking for at least two months

If all goes well, patients should feel less out of breath and develop fewer bronchitis and pneumonia infections. The risks that the disease is developing seriously should also decrease.

To participate in the study, you must be between 40 and 75 years old, have stopped smoking for at least two months, have suffered at least two exacerbations of symptoms in the past year with at least one hospitalization and follow the treatment. conventional background of COPD. Some other very specific medical criteria are required. If you are interested and you match the profile requested, you can contact the pulmonologist Nicolas Guibert directly at the hospital Larrey ([email protected]).

Currently, medical treatments and physiotherapy can help relieve the symptoms of COPD, help patients to exercise more easily and improve their quality of life. However, smoking cessation is the most effective treatment for slowing the disease in smokers, says the WHO. It helps slow the progression of the disease and the risk of dying.
