Diagnostic Considerations

The types of infections and infectious microorganisms that occur in leukocyte adhesion deficiency (LAD) type 1 resemble those that occur in patients with neutropenia. Other defects of neutrophils, such as chronic granulomatous disease (CGD) and hyperimmunoglobulin E (HIE) produce similar susceptibility to infections. However, in both CGD and HIE, lymphadenopathy and splenomegaly occur as well as neutrophil inflammatory response to infections.
