title: Leukocyte adhesion deficiency: a case report and review.
abstract: Leukocyte adhesion deficiency (LAD) is a rare inherited primary immunodeficiency disorder characterized by the presence of a defect of phagocytic function resulting from a lack of leukocyte cell surface expression of β₂ integrin molecules (CD11 and CD18) that are essential for leukocyte adhesion to endothelial cells and chemotaxis. A small number of patients with LAD-1 have a milder defect, with residual expression of CD18. These patients tend to survive beyond infancy; they manifest progressive severe periodontitis, leading to partial or total premature loss of the primary and permanent dentitions. Close cooperation with pediatricians and immunologists is often the key to successful management of pediatric patients with LAD. The purpose of this report was to present the case of a 5-year-old boy with moderate leukocyte adhesion deficiency-1 and severe periodontitis, cellulitis and illustrate the need for periodic oral checkups to avoid the progression of oral diseases and prevent premature tooth loss.
