The acute chest syndrome.
Recent large clinical studies of the acute chest syndrome (ACS) have improved our understanding of its pathophysiology and epidemiology. However, there is still a need for better methods of distinguishing vaso-occlusion from fibrin or fat embolism, for rapid diagnostic tests to make positive identifications of microbial infection, for adjunctive therapies that would affect prognosis, and for identification of factors that influence prognosis. The difference in clinical course and severity between children and adults supports the results of current studies indicating multiple causes for ACS. The mainstay of successful treatment remains high-quality supportive care. The judicious use of transfusion therapy has a major role in preventing mortality in the absence of a specific therapy that consistently improves the clinical course.
