They found such a level in 14 of 16 episodes of bacterial infection but in only three of 35 episodes of vaso-occlusive crisis.In an attempt to evaluate this finding, we reviewed our experience with 15 episodes of septicemia and ten of meningitis that have been reported in part in a previous communication.1 Cases were selected on the basis of age (younger than 18 years) and a positive bacterial culture of blood or CSF. In addition, we reviewed the records of 30 children hospitalized for painful crisis in whom infection was not considered a contributing factor. The first leukocyte and differential cell count obtained within 24 hours of the
