Bronchial thermoplasty: interventional therapy in asthma

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Medical Devices

Background:

• Severe bronchial asthma often persists despite optimal medical management.
• Bronchoconstriction due to airway smooth muscle contributes to asthma symptoms.
• New therapeutic approaches are needed for refractory asthma cases.

Purpose of the Study:

• To evaluate bronchial thermoplasty as a treatment for severe symptomatic asthma.
• To assess the impact of bronchial thermoplasty on airway smooth muscle and bronchoconstriction.
• To analyze the efficacy and safety of bronchial thermoplasty in clinical trials.

Main Methods:

• Bronchial thermoplasty involves three bronchoscopic sessions applying heat to airways.
• Randomized, controlled clinical trials were conducted to assess treatment outcomes.
• Data on quality of life, exacerbations, emergency visits, and lung function were collected.

Main Results:

• Bronchial thermoplasty improved quality of life and reduced severe exacerbations and emergency visits.
• No significant reduction in airway hyperresponsiveness or improvement in FEV1 was observed.
• Short-term adverse events included increased exacerbations, infections, and hospitalizations.

Conclusions:

• Bronchial thermoplasty is a viable option for severe asthma, improving symptoms and reducing exacerbations.
• Long-term follow-up suggests clinical and functional stability in treated patients.
• Further research is needed to identify specific asthma phenotypes that benefit most from this intervention.
