Asthma and New Discoveries in Treatment

Asthma

Asthma, a chronic respiratory condition affecting approximately 5.4 million people in the UK, presents with symptoms such as wheezing, coughing, shortness of breath, and a tight chest. These symptoms are often triggered by allergens like pollen, dust, or environmental factors, leading to airway constriction or asthma attacks, which can be life-threatening​

What Causes Asthma?

Asthma is primarily understood as an inflammatory condition where airways become hypersensitive, leading to swelling and excess mucus production. However, new research from King’s College London has highlighted an alternative mechanism. This study found that during an asthma attack, mechanical constriction of airways damages the epithelial cells lining the airways. This damage exacerbates inflammation and mucus production, further worsening symptoms. This discovery opens the door to potential treatments that target the root cause rather than just the symptoms​.

How is Asthma Diagnosed?

Asthma is diagnosed through a combination of a patient’s medical history, physical examination, and specific lung function tests. Doctors often begin by assessing symptoms like wheezing, coughing, or shortness of breath, and identifying possible triggers or family history of asthma. Spirometry is a key test that measures how well the lungs function, while other tests, such as peak flow monitoring or FeNO (Fractional Exhaled Nitric Oxide), can confirm airway inflammation. Allergy testing and exercise or challenge tests may also be conducted to determine specific triggers. Early diagnosis is crucial for effective treatment and management.

Symptoms of Asthma

Asthma is a chronic condition that causes inflammation and narrowing of the airways. Common symptoms include:

  1. Wheezing: A whistling or squeaky sound when breathing.
  2. Shortness of Breath: Difficulty catching your breath, especially during physical activity or at night.
  3. Chest Tightness: A sensation of pressure or constriction in the chest.
  4. Coughing: Persistent coughing, often worse at night or early in the morning.
  5. Fatigue: Feeling unusually tired, especially after exertion, due to reduced oxygen levels.

These symptoms can vary in frequency and intensity, and they may worsen during exposure to triggers such as allergens, cold air, or exercise.

Symptoms of an Asthma Attack

An asthma attack occurs when the symptoms of asthma become severe, often requiring immediate medical attention. During an attack, you may experience:

  1. Severe Wheezing: Louder or more persistent wheezing than usual.
  2. Rapid Breathing: Breathing becomes faster and more laborious.
  3. Chest Pain or Tightness: Increased pressure or discomfort in the chest area.
  4. Severe Shortness of Breath: Difficulty speaking or completing sentences due to lack of air.
  5. Blue Lips or Fingernails: A sign of reduced oxygen levels (cyanosis).
  6. Confusion or Drowsiness: Indicating a lack of oxygen to the brain.

Managing Symptoms

If you experience symptoms of an asthma attack:

  • Use a reliever inhaler (e.g., a blue inhaler) as prescribed.
  • Sit upright and avoid lying down.
  • Seek medical attention if symptoms do not improve after using your inhaler or if they worsen.

Proper management, including avoiding triggers, adhering to a treatment plan, and regular check-ups, can reduce the likelihood of severe attacks.

Current Treatment Approaches

The traditional approach to management focuses on minimizing symptoms through:

  • Inhalers: Relievers and preventers manage inflammation and open airways.
  • Medications: Oral steroids or biologics are used for severe cases.
  • Self-management Plans: Monitoring and avoiding triggers are key strategies​

A Step Forward in Treatment

The King’s College study identified a compound, gadolinium, which may prevent epithelial damage during asthma attacks in preclinical models. While this represents a promising avenue, more research is needed to assess its safety and effectiveness in humans​. See article.

If you suspect asthma or are managing symptoms, consider consulting healthcare professionals for a personalised care plan. Advances in research are paving the way for innovative treatments that could significantly improve outcomes for asthma patients.
