[Successful pregnancy in a severely hypoxemic patient with pulmonary alveolar proteinosis].

Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by abnormal accumulation of a lipoproteinaceous material in the alveoli, which may lead to respiratory failure and has an associated high risk for infections. The mainstay treatment for PAP is whole lung lavage. A pregnant woman, previously diagnosed with primary PAP, the most common form of PAP, was admitted with dyspnea and worsening respiratory function. In one month period, a whole-lung bronchopulmonary lavage was performed twice, with clinical and functional improvement. Pregnancy was carried to term and a healthy baby was delivered. The mechanisms of respiratory impairment are discussed as well as treatment options and response.
