Chronic granulomatous disease. Diagnosis by the dihydrorhodamine assay

Diagnosis of Chronic Granulomatous Disease

Detection of inheritance pattern in thirty-three Mexican males with chronic granulomatous disease through 123 dihydrorhodamine assay.

BACKGROUND There are two inheritance patterns, the X-linked recessive (XL) pattern and the autosomal recessive pattern. There is no information on the predominant inheritance pattern of male patients with chronic granulomatous disease (CGD) in Mexico. OBJECTIVE The aim of this study was to determine the inheritance pattern in a cohort of Mexican male patients with CGD by means of the detectio...

A highly sensitive chemiluminescence assay for superoxide detection and chronic granulomatous disease diagnosis

Reactive oxygen species (ROS) produced by neutrophils are crucial for defense against infectious diseases, and the adequate measurement of ROS levels is an important way to evaluate the possibility of infections. The fluorescent probe dihydrorhodamine 123 has been applied exclusively to the measurement of ROS thus far. We developed a novel method for detecting ROS, which utilizes the chemilumin...

prenatal diagnosis of chronic granulomatous disease in a male fetus

mutations in any of four known nadph-oxidase components lead to cgd. x-linked cgd (x-cgd) is caused by defects in cybb, the gene that encodes gp91-phox. autosomal recessive (ar) cgd is caused by defects in the genes for p47 phox, p22-phox or p67-phox. the aim of this study was to screen the molecular defect in the fetus of an x-cgd carrier mother and postnatal confirmation of the results. in a ...

Postmortem diagnosis of chronic granulomatous disease: how worthwhile is it?

A previously healthy 11 year old boy died unexpectedly after a rapid course of progressive pneumonia. Postmortem microbiology and histopathology suggested an underlying diagnosis of chronic granulomatous disease. This was confirmed by neutrophil oxidative burst and gene mutation analysis of other family members, one of whom benefited from early bone marrow transplantation.
