patients  with  primary  antibody  deficiencies  (pad)  are  susceptible  to  recurrent  and chronic infections and a variety of complications. this study was performed to assess quality of life (qol) of pad patients who were under long term treatment and regular follow-up.thirty six adults with proved diagnosis of pad, who had received regular intravenous immunoglobulin replacement therapy, we...

X-linked lymphoproliferative (XLP) disease is a primary immunodeficiency caused by a defect in the SH2D1A gene. At least 3 major manifestations characterize its clinical presentation: fatal infectious mononucleosis (FIM), lymphomas, and immunoglobulin deficiencies. Common variable immunodeficiency (CVID) is a syndrome characterized by immunoglobulin deficiency leading to susceptibility to infec...

BACKGROUND In endemic regions, histoplasmosis is often seen in hosts with defective cell mediated immunity. We report a case of disseminated histoplasmosis in a patient with common variable immunodeficiency (CVID), a disorder mainly characterized by B cell defects. CASE A 35 year old male with CVID developed fever, headache, dyspnea and pancytopenia within few weeks of swimming in the Tenness...

The peripheral blood lymphocyte surface markers and clinical features of 38 patients with common variable immunodeficiency (CVID) were assessed. These studies identified a subset of CVID consisting of 14 of the 38 patients with a distinctive T-cell immunophenotype and clinical findings. The phenotypic changes were characterized by an abnormally low CD4/CD8 ratio (less than or equal to 0.9) due ...

Several autoimmune diseases have been reported to be associated with common variable immunodeficiency disease (CVID), including rheumatoid arthritis and Sjögren's syndrome. On the other hand, approximately 20-30% of patients with rheumatoid arthritis develop secondary Sjögren's syndrome. A 26-year-old woman had a 6-year history of chronic symmetric polyarthritis and 3-year history of sicca synd...

Common variable immunodeficiency (CVID) is a primary immune disorder characterized by impaired antibody production, which is in many instances secondary to defective T-cell function (T-CVID). We have previously identified a subset of patients with T-CVID characterized by defective T-cell receptor (TCR)-dependent protein tyrosine phosphorylation. In these patients, ZAP-70 fails to be recruited t...

INTRODUCTION Common variable immunodeficiency disorder (CVID) is a heterogeneous syndrome, characterized by deficient antibody production and recurrent bacterial infections in addition abnormalities in T cells. CD4(+)CD25(high) regulatory T cells (Treg) are essential modulators of immune responses, including down-modulation of immune response to pathogens, allergens, cancer cells and self-antig...
