Chediak-Higashi Syndrome

چکیده
Chediak-Higashi syndrome which appears to be a lysosomal disease (Douglas and Fudenberg, 1969; White, 1966) is characterized by partial albinism, photophobia, recurrent infections, hepatosplenomegaly, and a distinctive leucocyte anomaly (Chediak, 1952; Higashi, 1954). Available genetic and fine structural studies suggest that the condition is inherited as an autosomal recessive trait (Sadan et al., 1965; Douglas, Blume, and Wolff, 1969). Chromosome studies have been done in a few cases, but as expected have not shown any significant numerical chromosomal abnormalities (Kritzler et al., 1964; Rosenszajn et al., 1969). The condition does not seem to be confined to a particular population group, since patients with this syndrome have been reported from various parts of the world. The purpose of this communication is to report a case of Chediak-Higashi syndrome from Turkey, in which chromosome studies revealed an unexpected and unusual abnormality in the form of partial monosomy for a G group chromosome (45,XY,G 46,XY/46,XY,Gr).

متن کاملChediak-Higashi-syndrome cultured fibroblasts
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,...

متن کاملDefective granulocyte chemotaxis in the Chediak-Higashi syndrome.
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...

Chemotaxis of mononuclear leukocytes from humans, mink, and cattle was evaluated in vitro using a morphologic Boyden chamber technique and a new 51-Cr-labeled mononuclear radioassay with a double micropore filter system. Significantly decreased mononuclear leukocyte chemotactic response were noted when human, mink, or cattle Chediak-Higashi cells were tested using autologous serum or endotoxin-...
