Background: Bronchiectasis is a disease with a global impact, but most published data come from high-income countries. We aimed to describe the clinical characteristics of patients with bronchiectasis in China.
Methods: The Chinese Bronchiectasis Registry (BE-China) is a prospective, observational cohort enrolling patients from 111 hospitals in China.
Rationale: The Bronchiectasis Health Questionnaire (BHQ) is a concise, self-administered and disease-specific instrument for measuring health-related quality-of-life (HRQoL) in bronchiectasis.
Objectives: To investigate the psychometric properties of simplified Mandarin BHQ and determine the minimum clinically important difference (MCID) as a reliable clinical endpoint for assessing the efficacy of bronchiectasis treatments.
Methods: A longitudinal, randomized controlled trial cohort of 357 patients treated with tobramycin inhalation solution or saline inhalation for Pseudomonas aeruginosa infection, along with a cross-sectional observational cohort including 436 patients with bronchiectasis were analyzed.
Background: Lung abscess in the apical segment of the lung is not rare and is often underestimated in clinical practice. However, the clinical features of apical segment lung abscess (AL) have scarcely been reported. Hence, this study aimed to determine the clinical characteristics of AL and explore moderate therapeutic strategies.

We aimed to evaluate the covariates affecting meropenem PK and the performance of different dosing regimens to optimize the PK/pharmacodynamic target.
Methods: Population PK analysis was performed using non-linear mixed-effects modeling.
Background: Bronchiectasis has high rates of hemoptysis and recurrent hemoptysis, which is inconsistent among various etiologies. Idiopathic bronchiectasis and post-tuberculous bronchiectasis are two important etiologies in China, but the differences in clinical features and risk factors of recurrent hemoptysis have not been elucidated.
Methods: Patients hospitalized for idiopathic bronchiectasis or post-tuberculosis bronchiectasis were included.
Background: Allergic bronchopulmonary aspergillosis (ABPA) is characterized by enhanced T2 inflammatory response. Fractional exhaled nitric oxide (FeNO) measurement has been used as a valuable tool in predicting the development and management of asthma, another typical T2 inflammation. However, the clinical significance of FeNO in ABPA remains unclear.

Initiating antibiotics early may lead to the eradication of PA. Here we outline the design of a trial (ERASE; NCT06093191) assessing the efficacy and safety of inhaled tobramycin, alone or with oral ciprofloxacin, in bronchiectasis patients with a new isolation of PA.

In this study, we identified the putative regulatory genes in an albino mutant of using comparative physiology and transcriptome analysis. The degeneration of chloroplasts, low chlorophyll (Chl) content and reduced photosynthetic capacity were observed in albinotic compared to normal lines.

The aim of this study is to investigate whether baseline symptoms, assessed using the Quality-of-Life Bronchiectasis Respiratory Symptom Scale (QoL-B-RSS) and its individual component scores, could predict future exacerbation risk in patients with bronchiectasis. The study included 436 adults with bronchiectasis from three tertiary hospitals.

The Cepheid 3-gene Host Response Fingerstick Blood Prototype Test (MTB-HR) quantifies relative mRNA levels of a 3-gene signature (, , and ) from a whole-blood sample on the GeneXpert platform. The objective of the present study was to evaluate the performance of the MTB-HR to distinguish between active tuberculosis (ATB), latent infection (LTBI), other pulmonary diseases, and healthy volunteers at a tertiary care centre.

Bronchoscopic lung volume reduction (BLVR) is a feasible, safe, effective and minimally invasive technique to significantly improve the quality of life of advanced severe chronic obstructive pulmonary disease (COPD). In this study, three-dimensional computed tomography (3D-CT) automatic analysis software combined with pulmonary function test (PFT) was used to retrospectively evaluate the postoperative efficacy of BLVR patients. The purpose is to evaluate the improvement of lung function of local lung tissue after operation, maximize the benefits of patients, and facilitate BLVR in the treatment of patients with advanced COPD.

However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA.

Methods: A retrospective cohort was conducted of patients with idiopathic bronchiectasis who received BAE from 2015 to 2019 at eight centers.
Background: The high-resolution computed tomography (HRCT) score is an important component of the severity and prognosis score of pulmonary alveolar proteinosis (SPSP). However, the HRCT score in SPSP only considers the extent of opacity, which is insufficient.
Methods: We retrospectively evaluated HRCT scores for 231 patients with autoimmune pulmonary alveolar proteinosis (APAP) from three centers of the China Alliance for Rare Diseases.
Background: Emerging experimental and epidemiological evidence highlights a crucial cross-talk between the intestinal flora and the lungs, termed the "gut-lung axis". However, the function of the gut microbiota in bronchiectasis remains undefined. In this study, we aimed to perform a multi-omics-based approach to identify the gut microbiome and metabolic profiles in patients with bronchiectasis.

We aim to provide suggestions to the government for managing serious infectious disease outbreaks in remote regions having relatively poor medical resources. Basic reproduction number (R), incubation period, time from symptom onset to confirmation, and duration of hospitalization were analyzed.

However, it is not clear which of the biomarkers is more sensitive to the severity of the patient's condition.
Methods: APAP patients numbering 151 were enrolled in this study.
