Treatment Monitoring for NTM Infections With a Symptom Diary

Condition(s) studied

Investigational drug(s) / intervention(s)

Filling in a symptom diary: Each patient will receive a diary form in which they are asked to record their symptoms, body temperature, and body weight on a daily basis. This approach is intended to provide a comprehensive overview of the disease course and the impact of treatment over time. Depending on hospitalization status, disease severity, treatment progress, and national treatment guidelines, clinical, microbiological, and radiological follow-up assessments will be performed as part of routine care at intervals ranging from weekly to monthly. No additional study visits or microbiological or radiological diagnostics outside of standard clinical care will be conducted.

Study summary

The primary aim of the study is to investigate the correlation between patient-reported symptoms recorded in the diary and the microbiological and radiological disease course in patients with pulmonary infections caused by nontuberculous mycobacteria (NTM).

Eligibility

Primary outcome measure(s)

• Degree of correlation of the symptom diary with radiology — 6 months from enrolement
  The primary endpoint of the study is the degree of correlation between patient-reported symptoms recorded in the diary in patients with pulmonary infections caused by nontuberculous mycobacteria (NTM) and the radiological course of the disease. Radiological course of the disease is assessed by a radiological composit measure consisting of an ordinal scale for nodule extent, consolidation extent, bronchiectasis severity and -extent, mucus plugging, cellular bronchiolitis severity and -extent, cavity diameter, -wall thickness, and number of cavities. Worsening (+1, step up) and improvement (-1 step down) are added and show overall worsening (\>= +1), overall improvement (\<= -1) or stable disease (= +/-0).
• Degree of correlation of the symptom diary with microbiology — 6 months from enrolment
  The primary endpoint of the study is the degree of correlation between patient-reported symptoms recorded in the diary in patients with pulmonary infections caused by nontuberculous mycobacteria (NTM) and the microbiological course of the disease, assessed by \- the mycobacterial load in sputum microscopy
• Degree of correlation of the symptom diary with microbiology — 6 months from enrolment
  The primary endpoint of the study is the degree of correlation between patient-reported symptoms recorded in the diary in patients with pulmonary infections caused by nontuberculous mycobacteria (NTM) and the microbiological course of the disease, assessed by \- time to positivity in liquid culture
• Degree of correlation of the symptom diary with microbiology — 6 months from enrolment
  The primary endpoint of the study is the degree of correlation between patient-reported symptoms recorded in the diary in patients with pulmonary infections caused by nontuberculous mycobacteria (NTM) and the microbiological course of the disease, assessed by \- treatment duration until culture conversion (defined as the absence of detectable mycobacteria using the aforementioned methods)
