Clinical profile of leukocyte adhesion deficiency type I

Abstract: Leukocyte adhesion deficiency type I (LAD-I) is a rare, inherited immunodeficiency with defect in the recruitment of leukocyte to the site of inflammation. Patients with severe LAD-I have absent or markedly reduced expression of CD18 and CD11. Here we report clinical profile of 7 cases of LAD-I diagnosed at our center over a period of 3 years. Recurrent skin and mucous membrane infections were the major presenting manifestations. All children had a history of delayed cord separation.

“…To the Editor, Leukocyte adhesion deficiency type I (LAD-I) is a rare autosomal recessive primary immunodeficiency disorder that is caused by mutations in ITGB2 gene encoding b2 subunit (CD18) of integrins (1). Integrins are required for neutrophil adhesion to endothelium during their emigration to inflammatory site.…”

“…Clinical suspicion is confirmed with integrins detection on neutrophil surface by flow cytometry. Worldwide, only about 300 cases have been reported so far and incidence is one in one million (1). However, due to high rate of consanguineous marriages in Pakistan, this incidence is expected to be higher.…”

“…No killing studies or molecular analyses were performed. In few cases of LAD I mutational studies were performed and ITGB2 gene mutation was observed 10 . In IFN‐γ and IL‐12 loop deficiency diagnosis was made by generation of IFN‐γ and IL‐12 by mononuclear cells after BCG stimulation.…”

“…Only about 300 cases of LAD 1 have been reported worldwide 2 . In India, even though there is a high rate of consanguinity, only a few cases of this recessive disorder have been reported 3 . Pathogenically, LAD is characterized by loss of the leucocyte ability to adhere to the endothelium during the inflammatory cascade, thus preventing their migration to the infected tissues.…”
