Summary
Diabetes in patients with bronchiectasis is associated with poorer nutritional status, more severe symptoms, and increased risk of acute exacerbation. These patients also face a higher financial burden due to the condition.
Area of Science:
- Pulmonology
- Endocrinology
- Clinical Medicine
Context:
- Bronchiectasis is a chronic respiratory condition characterized by permanent enlargement of the airways.
- Diabetes mellitus is a metabolic disorder with significant systemic implications.
- The interplay between these two conditions requires further investigation to understand their combined impact on patient outcomes.
Purpose:
- To investigate the clinical characteristics, laboratory findings, infection patterns, and disease severity in patients with bronchiectasis and co-existing diabetes mellitus.
- To compare these parameters between a matched cohort of bronchiectasis patients with and without diabetes.
Summary:
- A retrospective study of 1,310 bronchiectasis inpatients identified 78 with diabetes. Propensity score matching was used to compare clinical data, lab results, and disease severity between bronchiectasis-diabetes and bronchiectasis non-diabetes groups.
- Results indicated that patients with bronchiectasis and diabetes were older, had lower pre-albumin levels, and experienced more severe symptoms (higher mMRC scores), increased acute exacerbations, and higher hospitalization costs.
- Furthermore, the Bronchiectasis Severity Index (BSI) score was significantly higher in the bronchiectasis-diabetes group, with positive correlations between blood glucose levels and BSI score, and a negative correlation with pre-albumin.
Impact:
- Diabetes significantly worsens the clinical presentation and outcomes of bronchiectasis, leading to poorer nutritional status and increased disease severity.
- Patients with bronchiectasis and diabetes exhibit a higher risk of acute exacerbations and a greater economic burden.
- These findings highlight the need for integrated management strategies addressing both diabetes and bronchiectasis to improve patient prognosis and reduce healthcare costs.

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
