In this report we describe a patient with persistent neutropenia whose neutrophils showed increased adhesion in a microplate assay. In three separate assays, from 12.5% to 13.7% of the patient's blood neutrophils exhibited spontaneous (unstimulated) adhesion to fetal bovine serum-coated microplate wells, much higher than adhesion of cells from healthy controls (1.9% +/- 2.5 SD, n = 20). The difference of spontaneous adhesion between the patient's and control neutrophils was even higher when cells from a skin-window exudate were examined (patient: 42.1-100% adhesion; control: 3.6% +/- 3.5 SD, n = 20). Over 80% inhibition of the increased adhesion was produced by the 60.3 anti-CD 18 monoclonal antibody, suggesting an involvement of beta 2-integrins.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D005122 Exudates and Transudates Exudates are fluids, CELLS, or other cellular substances that are slowly discharged from BLOOD VESSELS usually from inflamed tissues. Transudates are fluids that pass through a membrane or squeeze through tissue or into the EXTRACELLULAR SPACE of TISSUES. Transudates are thin and watery and contain few cells or PROTEINS.

D013481 Superoxides Highly reactive compounds produced when oxygen is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of enzymes and during the oxidation of hemoglobin to METHEMOGLOBIN. In living organisms, SUPEROXIDE DISMUTASE protects the cell from the deleterious effects of superoxides. Superoxide Radical,Superoxide,Superoxide Anion
D015703 Antigens, CD Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.
