Lymphocyte subpopulations in primary immunodeficiency disorders.

Lymphocyte subpopulations in primary immunodeficiency disorders.

Venous blood mononuclear cells from 42 children with primary immunodeficiency disorders and from controls matched for age were studied for lymphocyte subpopulations by E rosetting, surface immunoglobulin, and a panel of anti T cell monoclonal antibodies (OKT series). In 3 cases of severe combined immunodeficiency (SCID) due to adenosine deaminase deficiency, very few circulating T or B cells we...

ALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Primary Immunodeficiency Disorders

Immunodeficiency is a common thought among both patients and physicians when confronted with what is perceived as an excessive number, duration, or severity of infections. Because of this, the starting point for evaluating patients for suspected immunodeficiency is based on what constitutes ”too many infections.” It generally is agreed that children with normal immune systems may have an averag...

Primary Immunodeficiency Disorders

Selective IgA deficiency (IgAD) is the most common primary genetic immune defect, with high prevalence in Western countries and relatively low prevalence in the East. The laboratory definition of IgAD is based on the measured serum component. However, the important manifestations of deficiency of IgA, the most prevalent of human antibodies, relate to the absence of secretory IgA, which covers a...
