Living with Acute interstitial pneumonia

A rare, serious lung condition that comes on and gets worse quickly, starting with cough, fever, and shortness of breath.

Understanding Acute interstitial pneumonia

Acute interstitial pneumonia (AIP) is a rare and serious condition that affects the lungs.

Symptoms develop and progress quickly. Early on, people may have cough, shortness of breath, and fever. This is followed by rapid onset of respiratory failure, and most people need a ventilator to help with breathing. GARD lists the onset as adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Dry cough
  • Trouble breathing (dyspnea)
  • Fever
  • Tiredness (fatigue)
  • Fast breathing (tachypnea)
  • Low blood oxygen level (hypoxemia)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include lung and breathing specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Children's Interstitial Lung Disease Foundation may keep lists of experts for this condition.
