Results In our service, a hundred and thirty patients with the diagnosis of a primary immunodeficiency are followedup and from this sample we have four patients with AT. Acessing clinical history and the laboratory findings becomes clear that a large variability occurs concerning their immune system. All subjects presented recurrent infections, especially sinopulmonary . In laboratory evaluatio...

Background: Acute lymphoblastic leukemia (ALL) is the most common type of leukemia among children. Immunoglobulin A is the most numerous immunoglobulin isotype in mucosal secretion.  Immunoglobulin A (IgA) deficiency can increase risk of cancer in patients. Since few studies have been done on relation between serum IgA and ALL, this study was attempted to evaluate serum IgA in ALL patients...

BACKGROUND AGA IgA II and AGA IgG II have recently been suggested as reliable tools for celiac disease (CD) diagnosis. We compared their utility for diagnosis and monitoring CD in children with that of tTG IgA, an established CD marker. METHODS We studied a cohort of 161 CD and 129 control children in whom CD was histologically confirmed or ruled out. We followed 37 children with CD on a glut...

We describe an interesting case of severe asthma who was not showing satisfactory response to standard treatment. Investigations revealed him to be suffering from allergic bronchopulmonary aspergillosis (ABPA). After starting systemic steroids he showed marked improvement initially only to have recurrent symptoms within a year. He was investigated further and found to have chronic pulmonary asp...

Common variable immunodeficiency (CVID) and selective IgA deficiency (SIgAD) are the most common primary immunodeficiencies in human. Both diseases share clinical manifestation and molecular defects. Increased apoptosis may be one of the mechanisms involved in the pathogenesis of CVID and SIgAD. Elevated apoptosis in this disorder leads to defective long-term survival of B-cells, reduced antibo...
