Acute chest syndrome in children with sickle cell anemia.
Vaso-occlusive crisis is the most common cause of morbidity in patients with sickle cell anemia (SCA). Those patients are frequently admitted with chest signs and symptoms suggesting an infective process. The term acute chest syndrome (ACS) is used to describe those chest episodes in SCA patients, and it is postulated that a primary bone vaso-occlusive crisis may be the cause of the acute chest syndrome in SCA patients. In this study we report 52 episodes of ACS in a group of 22 children with SCA. Chest pain, fever, and leukocytosis were a constant clinical finding. The hematological, radiological, and bacteriological studies are reported. There is a constant and significant fall in hemoglobin levels from 88 +/- 10 g/L (8.8 +/- 1.0 g/dl) to 68 +/- 15 g/L (6.8 +/- 5 g/dl). Unilateral or bilateral pulmonary basal infiltrations were found in 50 episodes. Pleural effusion was noticed in 60 episodes, and it was bilateral in three. No significant bacteriological findings were present.
