About this trial

Chinese herbs can facilitate sputum culture conversion, promote lesion absorption, and enhance clinical symptoms and quality of life for patients with Mycobacterium abscessus pulmonary disease (MAB-PD). The investigators aimed to evaluate the efficacy of Chinese herbs as adjunct therapy to improve cure rates or reduce recurrence rates during the continuation phase of MAB-PD treatment.

Trial outcomes

Primary outcomes

1

Clinical cure rate

Measured the change from the Baseline to the end of treatment. The sputum MAB culture was negative on three consecutive occasions, with at least a one-month interval between each, and there were no subsequent positive results.

Time frame
At the end of 52 weeks of treatment
2

Relapse or reinfection rates

Bacterial relapse is defined as the occurrence of at least two cultures and/or molecular biology tests identifying the same pathogenic M. abscessus strain as the initial infection after completing anti-M. abscessus treatment. When necessary, genotyping techniques may be employed to differentiate between relapse and reinfection. Reinfection refers to the emergence of different pathogenic strains or species in at least two positive cultures following the initiation of treatment.

Time frame
At the end of 52 weeks of treatment

Secondary outcomes

1

Time to sputum culture conversion

Measured the change from Baseline to the end of treatment

Time frame
From baseline to 52 weeks post-treatment completion
2

Absorption rate of lung lesions

The lung lesion absorption rate is assessed via chest imaging to evaluate changes in pulmonary infection lesions compared to the baseline at 26 and 52 weeks after enrollment. Patients with more than half of their lesions absorbed are classified as showing significant absorption; those with less than half absorption are considered to have absorption; those with no changes are deemed to show no change; and those with enlarged lesions or new lesions are regarded as demonstrating deterioration. The determination of the lung lesion absorption rate is made by professional radiology experts.

Time frame
Baseline, 26 weeks and 52 weeks
3

Rate of closure of lung cavities

The lung cavity closure rate is assessed through chest imaging to evaluate changes in lung cavities compared to the baseline at 26 and 52 weeks after enrollment. The clinical criteria for CT changes were as follows: Regarding changes in cavity size, scar healing, block healing, or disappearance were defined as closure. A reduction in cavity size by 1/2 or more was defined as reduction, a reduction in cavity diameter by less than 1/2 was classified as no change, and an increase in the cavity diameter by 1/2 or more was defined as increase. The determination of the lung lesion absorption rate is made by professional radiology experts.

Time frame
Baseline, 26 weeks and 52 weeks
4

Pulmonary function tests

Assess the patient's pulmonary function, specifically the changes in FEV1 (L), before treatment, as well as at 26 weeks and 52 weeks post-treatment

Time frame
Baseline, 26 weeks and 52 weeks
