Leucocyte adhesion deficiency presenting as a chronic ileocolitis.

Leucocyte adhesion deficiency presenting as a chronic ileocolitis.

CD11/CD18 leucocyte glycoprotein deficiency is a rare, congenital adhesion molecule disorder which, in its severe form, is usually fatal. Leucocytes in affected subjects have abnormal migration and adherence, rendering patients susceptible to life threatening infections. The CD11/CD18 integrins, and other adhesion molecules, are considered essential to the normal inflammatory response. It has b...

Leukocyte Adhesion Deficiency Type 1 Presenting as Leukemoid Reaction

The hallmarks of leukocyte adhesion deficiency (LAD) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. These molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. Over las...

Non-Hodgkin's lymphoma in a patient with leucocyte adhesion deficiency.

Leukocyte adhesion deficiency type 1 presenting as leukemoid reaction.

Leukocyte Adhesion Deficiency (LAD) is characterized by the inability of leukocytes, in particular neutrophilic granulocytes, to emigrate from the blood stream towards sites of inflammation. Infectious foci are nonpurulent and may eventually become necrotic because of abnormal wound healing. LAD-I is characterized by the absence of the beta-2 integrins CD II and CD 18 on leukocytes. We present ...
