In the past, XLA was described as associated with several inflammatory conditions, but with adequate immune globulin treatment, these are presumed to have diminished. The actual prevalence is not known. A web-based patient survey was conducted December 2011- February 2012. Respondents were recruited from the Immune Deficiency Foundation (IDF) patient(More)
Approximately 85% of patients with defects in early B-cell development have X-linked agammaglobulinemia (XLA), a disorder caused by mutations in the cytoplasmic Bruton's tyrosine kinase (Btk). Although Btk is activated by cross-linking of a variety of cell-surface receptors, the most critical signal transduction pathway is the one initiated by the pre-B(More)
The United States Immunodeficiency Network (USIDNET) patient registry was used to characterize the presentation, genetics, phenotypes, and treatment of patients with Hyper IgM Syndrome (HIGM). The USIDNET Registry was queried for HIGM patient data collected from October 1992 to July 2015. Data fields included demographics, criteria for diagnosis, pedigree(More)
Primary immunodeficiency diseases (PIDs) comprise a heterogeneous group of rare disorders. This study was devised in order to compare management of these diseases in the northern hemisphere, given the variability of practice among clinicians in North America. The members of two international societies for clinical immunologists were asked about their(More)
OBJECTIVE This review will provide an overview of the most common clinical presentations of primary immunodeficiency (PI), navigating through various affected organ systems. The goal is to accurately portray the high variability of this disease and provide a resource that helps to raise the index of suspicion of PI among physicians, aid in recognition of(More)
Gene transfer into hematopoietic stem cells by gamma-retroviral vectors (RVs) is an effective treatment for inherited blood disorders, although potentially limited by the risk of insertional mutagenesis. We evaluated the genomic impact of RV integration in T lymphocytes from adenosine deaminase-deficient severe combined immunodeficiency (ADA-SCID) patients(More)
BACKGROUND Both hyper-IgE syndrome and food allergies can result in the early onset of skin rash, eosinophilia, and markedly elevated serum IgE. Occasionally, it can be difficult to distinguish the 2 disorders. Most patients with hyper-IgE syndrome do not have food allergy. OBJECTIVE To describe a child with cow's milk allergy associated with hyper-IgE(More)
BACKGROUND The time from symptom onset to diagnosis for patients with primary immunodeficiency diseases (PIDD) is an average of 12 years, but prompt diagnosis and treatment can promote best outcomes. OBJECTIVE Because the manifestations of PIDD are often sinopulmonary in nature, patients with undiagnosed PIDD are frequently referred to pulmonologists.(More)
The present uncertainty of which live viral or bacterial vaccines can be given to immunodeficient patients and the growing neglect of societal adherence to routine immunizations has prompted the Medical Advisory Committee of the Immune Deficiency Foundation to issue recommendations based on published literature and the collective experience of the committee(More)
Antihistamines have been used in the treatment of rhinitis since ancient times. Antihistamines can be used via oral or topical route for the treatment of allergic rhinitis, as well as nonallergic forms of rhinitis. The topical formulation of medications is the preferred treatment route used for many diseases. This article will investigate the differences in(More)
