Pulmonary Hemosiderosis in Children with Bronchopulmonary Dysplasia

الملخص EN

We describe a possible association between pulmonary hemosiderosis (PH) and a history of bronchopulmonary dysplasia (BPD).

Both patients were born at 28-week gestation and presented with PH at ages 22 months and 6 years, respectively.

Both initially presented with cough and tachypnea, and bronchoalveolar lavage showed evidence of hemosiderin-laden macrophages.

Initial hemoglobin levels were < 4 g/dL and chest radiographs showed diffuse infiltrates that cleared dramatically within days after initiation of intravenous corticosteroids.

In the first case, frank pulmonary blood was observed upon initial intubation, prompting the need for high frequency ventilation, immediate corticosteroids, and antibiotics.

The mechanical ventilation wean was made possible by the addition of mycophenolate mofetil (MMF) and hydroxychloroquine.

Slow tapering off of medications was accomplished over 6 years.

These cases represent a possible correlation between prematurity-associated BPD and PH.

We present a review of the literature regarding this possible association.

In addition, MMF proved to be life-saving in one of the PH cases, as it has been in pulmonary hemorrhage related to systemic lupus erythematosus.

Further studies are warranted to investigate the possible association between PH and prematurity-related BPD, as well as the use of MMF in the treatment of PH.
