Chronic pneumonitis of infancy is a rare lung disorder that affects infants. It is characterized by inflammation of the lungs, which can lead to difficulty breathing, coughing, and other respiratory symptoms. The cause of the disorder is unknown, but it is thought to be related to an immune system disorder. Treatment typically involves corticosteroids and other medications to reduce inflammation and improve breathing.

The symptoms of Chronic pneumonitis of infancy include:

-Persistent coughing
-Wheezing
-Rapid breathing
-Shortness of breath
-Chest pain
-Fever
-Loss of appetite
-Weight loss
-Fatigue
-Bluish skin color (cyanosis)

The most common cause of chronic pneumonitis of infancy is a viral infection, such as respiratory syncytial virus (RSV). Other causes include bacterial infections, such as Mycoplasma pneumoniae, and environmental exposures, such as secondhand smoke. In some cases, the cause of chronic pneumonitis of infancy is unknown.

1. Oxygen therapy: This is the most common treatment for chronic pneumonitis of infancy. Oxygen therapy helps to increase the amount of oxygen in the blood, which can help to reduce the symptoms of the condition.

2. Antibiotics: Antibiotics may be prescribed to help reduce the inflammation and infection in the lungs.

3. Corticosteroids: Corticosteroids may be prescribed to help reduce inflammation in the lungs.

4. Bronchodilators: Bronchodilators may be prescribed to help open up the airways and make it easier to breathe.

5. Nutritional support: Nutritional support may be necessary to help the infant gain weight and stay healthy.

6. Pulmonary rehabilitation: Pulmonary rehabilitation may be recommended to help the infant learn how to breathe more effectively
