Cystic Fibrosis (CF)

Genetic Disorder Causing Thick Mucus and Progressive Lung Damage

Cystic Fibrosis is a genetic condition that leads to the production of thick, sticky mucus in the lungs and other organs. This causes recurrent lung infections, progressive lung damage, and can lead to respiratory failure in advanced stages.

Understanding

What is Cystic Fibrosis?

Cystic Fibrosis is an inherited disorder affecting mucus-producing glands.

It leads to:

  • Thick, sticky mucus in lungs
  • Blocked airways
  • Frequent infections

It also affects:

  • Pancreas (digestive issues)
  • Sweat glands (salty sweat)
Warning Signs

Early Signs & Symptoms

Recurrent infections in young patients → Important diagnostic clue

In Children
Persistent cough, recurrent chest infections, poor growth
In Adolescents/Adults
Chronic cough with mucus, breathlessness, frequent hospitalizations
Advanced Stage
Severe lung damage, oxygen dependency, weight loss
Recurrent infections in young patients → Get evaluated
Risk Factors

Causes & Risk Factors

Primary Cause

Genetic mutation (inherited from both parents)

Risk Factors
  • Family history
  • Consanguinity
Progression

Disease Progression

Early Stage Mucus buildup
Moderate Stage Lung damage begins
Severe Stage Bronchiectasis
End Stage Respiratory failure

Transplant Evaluation

End Stage Lung Disease

Respiratory failure

Lung transplant required

Transplant Needed
Testing

Diagnosis & Tests

Sweat chloride test
Gold standard
Genetic testing
Chest imaging (HRCT)
Pulmonary function tests

Management

Treatment Options (Before Transplant)

1. Airway Clearance Therapy
  • Chest physiotherapy
  • Mucus clearance techniques
2. Medications
  • Antibiotics
  • Mucolytics
  • CFTR modulators
3. Nutritional Support
  • High-calorie diet
  • Enzyme supplements
4. Pulmonary Rehabilitation
  • Exercise and breathing training

When is Lung Transplant Needed?

Advanced lung damage

Frequent severe infections

Oxygen dependency

Poor quality of life

Early Management Improves Survival

Multidisciplinary care is essential

Medical Management vs Transplant
Medical Management

Stage: Early/Moderate • Goal: Control symptoms • Outcome: Improved survival

Lung Transplant

Stage: Advanced • Goal: Replace lungs • Outcome: Life-saving
