Chediak-Higashi syndrome is a rare autosomal recessive disorder due to a qualitative defect in leucocyte function characterized clinically by partial oculocutaneous albinism, recurrent bacterial infections, photophobia etc. The diagnostic feature is the presence of abnormal giant intracytoplasmic granules in neutrophils and their precursors. Here we report this syndrome in two siblings who pres...

primary immunodeficiencies (pid) are a group of disorders, characterized by an unusual susceptibility to infections. delay in diagnosis results in increased morbidity and mortality in affected patients. the purpose of this study was to determine the mortality rate of iranian immunodeficient patients referred to children medical center hospital affiliated to tehran university of medical sciences...

Aims-To determine whether neutrophil elastase and cathepsin G are expressed, at transcriptional or translational levels, in the bone marrow from a patient with Chediak-Higashi syndrome.Methods-Blood neutrophils were isolated from three patients with Chediak-Higashi disease and bone marrow was collected from one. Cell lysates were analysed for neutrophil elastase and cathepsin G activity by enzy...

Primary embryonic fibroblasts isolated from beige (Chediak-Higashi) mice develop pathognomonic giant granules in vitro. Inclusion in the culture medium of carbamylcholine (carbachol) or phorbol myristate acetate (PMA) results in the generation of morphologically normally granules. Chediak-Higashi fibroblasts are highly susceptible to shape changes induced by colchicine. This abnormal property i...

Chediak-Higashi Syndrome is a pathology caused by mutation in the LYST gene, characterized immunodeficiency, oculocutaneous albinism, and neurological dysfunction resulting from neutrophil changes. Homozygotes die first decade of life. The study about literature review different sources, with articles extracted SciELO, LILACS, MEDLINE, Google Scholar, PubMed databases, published between 2000 20...
