,Hyperimmunoglobulinemia E (Job syndrome) - Answer: An autosomal dominant condition
characterized by the triad of eczema, eosinophilia, and recurrent skin and pulmonary infections.
It is also associated with multiple connective tissue and skeletal abnormalities, including scoliosis,
hyperextensibility, pathologic fractures, retained primary dentition, craniosynostosis, and vascular
abnormalities
Nitroblue Tetrazolium Dye Test - Answer: It is used to detect the presence of NADPH oxidase, an
enzyme used by neutrophils to make oxygen radicals for killing bacteria. The test is positive when the
enzyme is present and not defective; the higher the blue score, the better the cell is at reproducing
reactive oxygen species.
NADPH oxidase is not affected in Job syndrome; thus, the nitroblue tetrazolium dye test should be
positive. A negative test, as in chronic granulomatous disease, will show a lack of NADPH oxidase.
