Rehabiliteringsøvelse og uddannelse af luftvejsklareringsteknik i ikke -nontuberkuløs mycobakteriel lungesygdom: En potentiel kohortundersøgelse

  • The goal of this observational study is to evaluate the effects of pulmonary rehabilitation and airway clearance education in adults with nontuberculous mycobacterial pulmonary disease (NTM-PD). The main questions it aims to answer are:

    • Does pulmonary rehabilitation and airway clearance training improve lung function, symptom relief, and quality of life in patients with NTM-PD?
    • Does this non-pharmacological intervention contribute to better sputum culture conversion rates?
  • Participants will:

    • Undergo pulmonary rehabilitation and airway clearance training over an 8-week period (biweekly sessions).
    • Receive evaluations at baseline, during the intervention, and follow-up assessments at 2 months, 6 months, and final study visit.
    • Undergo tests including pulmonary function tests (PFT), symptom assessments, bacteriologic evaluations, radiographic imaging (CT/X-ray), and quality of life surveys (EQ-5D-5L, CAT score).
  • This study aims to provide clinical evidence supporting the role of non-pharmacological treatments in the management of NTM-PD, potentially informing future treatment guidelines and improving patient outcomes.

Studiebefolkning

This study will enroll adult patients (≥20 years old) diagnosed with nontuberculous mycobacterial pulmonary disease (NTM-PD) based on the 2020 ATS guidelines. Participants will be recruited from outpatient pulmonary clinics at study sites. Eligible participants will undergo pulmonary rehabilitation and airway clearance training as part of a prospective observational study. The study focuses on assessing the effects of non-pharmacological interventions on lung function, symptom relief, and quality of life in patients with NTM-PD.

The cohort will include patients with clinically significant NTM species such as Mycobacterium avium, Mycobacterium intracellulare, Mycobacterium abscessus, Mycobacterium massiliense, and Mycobacterium kansasii. Participants will undergo baseline assessment, structured rehabilitation sessions, and follow-up evaluations at 2 months and 6 months. The study aims to provide real-world clinical evidence sup

Kohorter og interventioner

Gruppe / kohorte
NTM-PD Pulmonary Rehabilitation Cohort

This cohort consists of adults diagnosed with nontuberculous mycobacterial pulmonary disease (NTM-PD) who will undergo pulmonary rehabilitation and airway clearance training as part of a prospective observational study. Participants will receive an 8-week biweekly pulmonary rehabilitation program, including oscillating positive expiratory pressure (OPEP) therapy, high-frequency chest wall oscillation (HFCWO), huffing and coughing techniques, breathing exercises, and aerobic/strength training. They will be monitored at baseline, during treatment, and at 2-month and 6-month follow-ups, undergoing pulmonary function tests (PFT), bacteriologic assessments, radiographic imaging (CT/X-ray), symptom evaluations, and quality of life assessments (EQ-5D-5L, CAT score). This study aims to assess the effectiveness of non-pharmacological interventions in improving respiratory function, reducing symptoms, and enhancing quality of life in NTM-PD patients.

Tidsramme
Change in Pulmonary Function (FEV1 and FVC) from Baseline to 6 Months
Tidsramme: Baseline, 2 months, 6 months

Forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) will be measured using pulmonary function tests (PFTs) at baseline, after 2 months, and at 6 months to assess improvements in lung function following pulmonary rehabilitation and airway clearance training.

Baseline, 2 months, 6 months
Sputum Culture Conversion Rate
Tidsramme: Baseline, 2 months, 6 months

The percentage of participants achieving sputum culture conversion, defined as three consecutive negative mycobacterial cultures from respiratory samples collected at least one month apart, will be assessed.
