Progression of selective IgA deficiency to common variable immunodeficiency.
Selective IgA deficiency (IgAD) is the most common primary immunodeficiency in Caucasians. Although it is often asymptomatic, selected patients show an increased frequency of infections, allergies and autoimmune manifestations. Common variable immunodeficiency (CVID) is a primary antibody deficiency disease that shares many clinical features with IgAD. A common genetic basis for IgAD and CVID h...
متن کاملInterleukins and IgA synthesis. Human and murine interleukin 6 induce high rate IgA secretion in IgA-committed B cells
Freshly isolated murine PP B cells were cultured with 10 different cytokines, including IL-1 alpha, IL-2, IL-4, IL-5, IL-6, IL-7, IFN-gamma, TNF-alpha, and TGF-beta, to investigate a possible role for these cytokines in induction of Ig synthesis. Of interest was the finding that only IL-5 and both mouse recombinant (mr) and human recombinant (hr) IL-6 enhanced IgA synthesis. The effect was grea...
متن کاملAutoimmunity and infection in common variable immunodeficiency (CVID).
Common variable immunodeficiency (CVID) is a heterogeneous group of diseases, characterized by primary hypogammaglobulinemia. B and T cell abnormalities have been described in CVID. Typical clinical features of CVID are recurrent airway infections; lymphoproliferative, autoinflammatory, or neoplastic disorders; and autoimmune diseases among which autoimmune thrombocytopenia (ITP) is the most co...
متن کاملClinical and Immunological Spectrum of Common Variable Immunodeficiency (CVID).
We have analysed data from 150 patients initially classified as having CVID. About 10% had laboratory abnormalities suggesting known single gene disorders (eg: hyper-IgM syndrome), and in a few a genetic defect has been confirmed. We have attempted to sub-classify the remaining patients by analysis of their circulating lymphocytes. B lymphocyte markers have been used to estimate the numbers of ...
متن کاملDecreased cytokine-induced IgA subclass production by CD40-ligated circulating B cells in primary IgA nephropathy.
BACKGROUND In IgA nephropathy (IgAN), the abnormalities in the IgA immune system are apparently restricted to the IgA1 subclass in the systemic compartment, as evidenced by the antigen-specific responses to recall antigens. Since precursors of IgA producing B cells in human peripheral blood belong predominantly to the mucosal compartment, we took the opportunity to assess the capacity of circul...
