Autoimmunity to brain could play an etiopathogenic role in a subgroup of autistic patients. The frequency of serum anti-myelin-associated glycoprotein antibodies, as an index for autoimmunity to brain, and their relation to family history of autoimmunity were investigated in 32 autistic and 32 healthy matched children. Autistic children had significantly(More)
OBJECTIVE Cardiovascular autonomic neuropathy (CAN) in patients with rheumatic diseases may result in sudden death, possibly from arrhythmia and myocardial infarction due to its frequent association with microvascular disease. Autonomic dysfunction may contribute to initiation and perpetuation of rheumatic diseases. Thus, we aimed to assess cardiovascular(More)
The tumor suppressor protein p53 plays an important role in cell cycle regulation. One of the major features in rheumatic diseases is the abnormal proliferation of lymphocytes. p53 expression in peripheral blood mononuclear cells (by flowcytometry) and serum anti-p53 antibodies (by ELISA) were therefore measured in 18 children and adolescents with juvenile(More)
The β2 integrins are expressed exclusively on leukocytes and participate in many immune and inflammatory processes. This subfamily comprises four heterodimeric glycoproteins with a common β-subunit, designated β2 (CD18). Spontaneous mutations of the CD18 gene result in leukocyte adhesion deficiency type I (LAD-I). Low level of CD18 expression has also been(More)
Background: If exposed to oral poliovirus vaccine (OPV), persons with primary immune deficiency disorders (PID) are at increased risk of paralytic poliomyelitis; and can chronically excrete poliovirus. However, the risk of excretion of vaccine derived poliovirus among immunodeficient persons (iVDPV) is not well characterized. We present summary of data from(More)
Evidence that enables us to identify, assess, and access the small airways in asthma and chronic obstructive pulmonary disease (COPD) has led INTERASMA (Global Asthma Association) and WAO to take a position on the role of the small airways in these diseases. Starting from an extensive literature review, both organizations developed, discussed, and approved(More)
PURPOSE To evaluate the frequency of banana sensitization and allergy among a group of atopic Egyptian children in relation to parental/self reports. METHODS This is a case-control study included 2 groups of allergic children with and without history of banana allergy, each included 40 patients. They were subjected to skin prick test (SPT) using(More)
Giant cell arteritis (GCA) is rare in children. The kidneys are generally spared. We present a case of GCA in a 12-year-old girl with severe headache and tender scalp especially over the right temporal area. The right superficial temporal artery was cord like and nodular and the pulsations were barely felt. Several small tender nodular swellings were felt(More)
B cells from systemic lupus erythematosus (SLE) patients display signalling defects that may underlie disease pathogenesis activity.CD19 and CD22 play a major role as regulators of B-cell response. The aim of this study was to clarify the relationship between B cell surface markers namely CD19, CD20 and CD22 expression and clinical and laboratory indices of(More)
