Differential Diagnosis for Infant with Recurrent Pneumonia versus Pulmonary Hypertension (HTN) with BPD
Single Most Likely Diagnosis
- Chronic Lung Disease (CLD) of Prematurity: This is a common complication in premature infants with BPD, characterized by recurrent respiratory infections and pulmonary hypertension, making it a likely diagnosis given the infant's history of BPD and recurrent pneumonia.
Other Likely Diagnoses
- Pulmonary Hypertension (HTN) secondary to BPD: Infants with BPD are at increased risk of developing pulmonary hypertension due to chronic lung injury and vascular remodeling, which can lead to recurrent pneumonia-like symptoms.
- Recurrent Respiratory Infections: Infants with BPD are more susceptible to respiratory infections due to impaired lung function and immune system maturity, which can mimic or exacerbate symptoms of pulmonary HTN.
- Aspiration Pneumonia: Infants with BPD may have swallowing difficulties or gastroesophageal reflux, increasing the risk of aspiration pneumonia, which can present similarly to recurrent pneumonia.
Do Not Miss Diagnoses
- Congenital Heart Disease (CHD) with Pulmonary Hypertension: Although less common, undiagnosed CHD can lead to pulmonary hypertension and recurrent pneumonia-like symptoms, making it crucial not to miss this diagnosis.
- Cystic Fibrosis: This genetic disorder can cause recurrent respiratory infections and pulmonary hypertension, and although less likely, it is critical to consider due to its significant impact on management and prognosis.
- Immunodeficiency: Infants with immunodeficiency disorders are more prone to recurrent infections, including pneumonia, and may present with symptoms similar to pulmonary HTN.
Rare Diagnoses
- Surfactant Protein Deficiency: Rare genetic disorders affecting surfactant production can lead to chronic lung disease and symptoms similar to BPD and pulmonary HTN.
- Pulmonary Veno-Occlusive Disease (PVOD): A rare condition characterized by occlusion of the pulmonary veins, leading to pulmonary hypertension and symptoms that can mimic recurrent pneumonia.
- Alveolar Capillary Dysplasia: A rare congenital disorder affecting the development of the alveolar capillaries, leading to pulmonary hypertension and chronic respiratory symptoms.
