Summary
Asthma and obstructive sleep apnea often coexist, worsening asthma control. Screening for sleep apnea in severe asthma patients is recommended, though continuous positive airway pressure therapy
Area of Science:
- Pulmonology
- Sleep Medicine
Background:
- Asthma and obstructive sleep apnea (OSA) are chronic conditions impacting patient quality of life.
- Increasing evidence links OSA with severe, uncontrolled asthma, potentially worsening symptoms and exacerbations.
Purpose of the Study:
- To review the current understanding of the association between asthma and OSA.
- To highlight the need for OSA screening in severe asthma patients.
- To discuss the implications of continuous positive airway pressure (CPAP) therapy for asthma control.
Main Methods:
- Literature review of current research on asthma and OSA comorbidity.
- Analysis of potential underlying mechanisms.
- Evaluation of existing evidence on CPAP efficacy in comorbid patients.
Main Results:
- OSA is more prevalent in severe, uncontrolled asthma.
- Mechanisms linking asthma and OSA require further elucidation.
- CPAP therapy shows promising, yet not fully established, benefits for asthma outcomes.
Conclusions:
- OSA screening is advisable for patients with severe or uncontrolled asthma.
- Further research is essential to clarify the relationship and CPAP's role in managing comorbid asthma and OSA.

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
