title: Safety and Benefits of Bronchoalveolar Lavage and Lung Biopsy in the Management of Pulmonary Infiltrates in Children With Leukemia.
abstract: Children with leukemia are at risk of developing life-threatening opportunistic pulmonary infections. The role of bronchoalveolar lavage (BAL) and lung biopsy (BX) in the management of these patients is controversial. In this study, we evaluate the yield and safety of BAL and BX in children with leukemia.
  
  
  
  We reviewed the records of all children with leukemia who underwent either BAL or BX between 1997 and 2007 at the St Jude Children's Research Hospital.
  
  
  
  A total of 64 patients were included, of whom 35 (55%) had BX and 29 (45%) had BAL. Positive results were obtained in 69% of BAL cohort and in 46% of BX cohort. Both procedures resulted in change in antimicrobial coverage (77% in BX, 83% in BAL). Pulmonary hemorrhage occurred in 2 patients, and transient hypoxia was the most frequent complication. All resolved without negatively impacting the clinical course.
  
  
  
  Both BAL and BX are safe and useful in the management of children with leukemia and pulmonary disease.
