Most autosomal genetic causes of childhood-onset hypogammaglobulinemia are currently not well understood. Most affected individuals are simplex cases, but both autosomal-dominant and autosomal-recessive inheritance have been described. We performed genetic linkage analysis in consanguineous families affected by hypogammaglobulinemia. Four consanguineous families with childhood-onset humoral imm...
BACKGROUND The pathogenesis of some primary humoral immunodeficiencies, such as transient hypogammaglobulinemia of infancy (THI) and immunoglobulin (Ig) A deficiency, remains unknown and can render diagnosis problematic. OBJECTIVE In the present study, we used flow cytometry to analyze peripheral blood B-cell subsets in patients with THI and unclassified hypogammaglobulinemia (UCH), partial I...
We undertook this study to determine whether patients with late-onset hypogammaglobulinemia, who are at very high risk for gastric cancer, have a reduced secretion of gastrin after stimulation with food or bombe sin, a potent gastrin-releasing stimulus. We compared the plasma gastrin responses to bombesin and to a standard test meal in 18 patients with late-onset hypogammaglob ulinemia with t...

We report strongyloides hyperinfection in two patients with generalized hypogammaglobulinemia from multiple myeloma and nephrotic syndrome, despite a significant strongyloides-specific immunoglobulin G (IgG) response. In contrast to reports on animals, where human IgG was shown to be a protective antibody, our observation suggests that in humans, immunity to the infective-stage larvae is not pr...
Carbamazepine is used to control seizures. Its common side effects are sleep disorders, anorexia, nausea, vomiting, polydipsia, irritability, ataxia, and diplopia. Involvement of the immune system is rare, and few cases of decreased immunoglobulin levels have been reported. We describe a patient with low immunoglobulin levels due to carbamazepine use who presented with recurrent urinary tract i...
Genetic defects in MOGS, the gene encoding mannosyl-oligosaccharide glucosidase (the first enzyme in the processing pathway of N-linked oligosaccharide), cause the rare congenital disorder of glycosylation type IIb (CDG-IIb), also known as MOGS-CDG. MOGS is expressed in the endoplasmic reticulum and is involved in the trimming of N-glycans. We evaluated two siblings with CDG-IIb who presented w...
Severe pneumonia caused by a novel influenza A (H1N1) virus in an asymptomatic emphysematous smoker.
A 49-year-old female presented with diarrhea and a high fever followed by progressive dyspnea. Until this presentation, she had been healthy except for chronic dyspepsia and diarrhea. She had a smoking habit of 15 pack-years. Laboratory tests revealed lymphopenia, hypoalbuminemia and hypogammaglobulinemia. A rapid influenza test in combination with an RT-PCR assay revealed the presence of the n...
We present a case report of diffuse polypoid lesions of the digestive tract in which multiple endoscopic techniques (upper endoscopy, colonoscopy, and capsule endoscopy) were performed in order to complete and refine the diagnosis in a patient with severe hypogammaglobulinemia with recurrent infections, bronchiectasies and diffuse nodular lymphoid hyperplasia of the digestive tract. In patients...
