Phagocytic, antimicrobial, and metabolic functions were studied in leukocytes obtained from three patients with the Chediak-Higashi syndrome (CHS) and compared to normals, individuals, heterozygous for Chediak-Higashi syndrome, and two subjects with chronic granulomatous disease of childhood (CGD). Chediak-Higashi syndrome leukocytes showed normal ingestion of a variety of bacteria, Candida alb...

chediak - higashi syndrome (chs) is a rare, primary immunodeficiency disorder with an autosomal recessive (ar) inheritance and characterized by re¬current infection, partial occulocutaneous albinism and an accelerated phase. in this report we describe clinical and laboratory findings from 6 chs pa¬tients. clinical and laboratory information of six patients who were referred to our center during...

Chediak-Higashi-syndrome cultured skin fibroblasts were used to study the possible involvement of lysosomal enzymes and lysosomal dysfunction in this disorder. Our evidence indicated that Chediak-Higashi fibroblasts displayed a significant decrease in the specific activity of the acidic a-D-mannosidase (pH 4.2) compared with normal controls. Additional studies revealed a small, but significant,...

Chediak Higashi syndrome, is a rare autosomal recessive disorder characterised by oculocutaneus albinism, recurrent respiratory system infections and other pyogenic infections. Hemophagocytic lymphohistiocytosis can develop in any time of the life in patients with Chediak Higashi syndrome. A 14-month-old girl patient was diagnosed as hemophagocytic lymphohistiocytosis with the laboratory findin...

Chediak-Higashi Syndrome is an autosomal recessive disorder that affects intracellular vesicle formation. The diagnostic feature of Chediak-Higashi Syndrome is the presence of 'giant' lysosomes clustered near the nucleus. Lysosome morphology in macrophages is maintained by microtubules and microtubule-based motors, such as kinesin. Dramatic changes in lysosome morphology can be induced by lower...

The prevalence of hyperten-sion and its relationship with obesity: results from a national blood pressure survey in Eritrea. Faciès de l'hypertension artérielle en milieu professionnel...

chédiak-higashi syndrome is a rare autosomal recessive congenital immunodeficiency mainly characterized by a condition called oculo-cutaneous albinism. the affected subjects have light-colored hair, vision problems, blood clotting (coagulation) abnormalities and in adulthood varying neurologic disorders. recurrent infections, particularly viral infection with other disorders in childhood are us...

Elejalde syndrome is a rare autosomal recessive condition, with only 10 reported cases through 2001. It is characterized by silvery hair, pigment abnormalities, and profound central nervous system dysfunction. The differential diagnosis includes Griscelli and Chediak-Higashi syndromes, which present with silvery hair, pigment abnormalities, central nervous system alterations, and severe immunol...

In vivo and in vitro studies of granulocyte chemotaxis were performed in three patients with the Chediak-Higashi syndrome. Rebuck skin windows showed a decreased accumulation of leukocytes at an inflammatory site. Studies in Boyden chambers documented a cellular defect in granulocyte chemotaxis. The chemotactic response of Chediak-Higashi cells by this technique averaged approximately 40% of no...
