Alpha-1 antitrypsin deficiency (AATD) can mimic asthma symptoms, leading to diagnostic confusion. Increased clinician awareness of AATD screening in asthma patients is crucial for timely diagnosis and improved management.
Area of Science:
- Pulmonology
- Genetics
- Internal Medicine
Background:
- Asthma and alpha-1 antitrypsin deficiency (AATD) are distinct conditions that can coexist.
- AATD presents with variable symptoms, often overlapping with asthma, including dyspnea, wheezing, and cough, complicating diagnosis.
Purpose of the Study:
- To explore the relationship between AATD and asthma.
- To evaluate current practices for screening asthma patients for AATD according to guidelines.
Main Methods:
- A PubMed search was conducted using terms: alpha-1 antitrypsin, screening, and asthma.
- Study selection was based on authors' expert opinions.
Main Results:
- AATD can present with asthma-like symptoms, causing diagnostic challenges.
- Guidelines recommend AATD screening for asthma patients with chronic airflow obstruction.
- Lack of awareness across specialties leads to an average diagnostic delay of 8.3 years for AATD.
Conclusions:
- Enhanced awareness of AATD among clinicians managing asthma patients can improve diagnosis rates.
- Increased diagnosis of AATD can lead to optimized interventions and better patient outcomes.

Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma I: Introduction
Asthma III: Clinical Manifestations
Asthma: Pathogenesis and Management
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.
Asthma-IV: Diagnostic and Management
Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:
