Selective immunoglobulin (Ig) A deficiency is reported to occur in 1 in 16,000 in Japan and has been reported to be complicated with various autoimmune diseases. A 49-year-old woman was diagnosed as having autoimmune thyroid disease. Her serum IgA, IgM and IgG were revealed to be 4.1, 154 and 1930 mg/dl, respectively. Severe skin eruption which occurred with 30 mg/day of methimazole (MMI) or 30...

Two patients are described with Crohn's disease and selective IgA deficiency. Serum IgA was undetectable in each case, and immunoperoxidase studies of the lamina propria showed a gross diminution of IgA-bearing plasma cells. Peripheral blood lymphocytes, however, showed normal numbers of IgA-bearing lymphocytes. The typical clinical course and histology in these two patients suggest that IgA-me...

Immunoglobulin (Ig) A deficiency has long been recognized in patients with chromosome 18 abnormalities. We present the case of a young girl in whom a chromosome 18p deletion syndrome (46,XX,del[18][p11.1]) was associated not only with IgA deficiency, but also with an inability to make antibody to the unconjugated pneumococcal polysaccharide vaccine, Pneumovax II, indicating a concomitant specif...

Objective. To study NETosis parameters in patients with selective immunoglobulin A deficiency. Material and methods. We studied the features of peripheral blood 46 (21 males 25 females, mean age 37±12.7 years) a confirmed diagnosis Results. Аctivation (NET30SP, NET30ST, NET150SP NET150ST, р<0.001) was found IgA deficiency relative to comparison group. The maximum degree increase leukocyte ob...

Selective IgM immunodeficiency (SIgMID) is a heterogeneous disorder with no known genetic background and may occur as a primary or a secondary condition. Celiac disease has been reported in association with several humeral immunodeficiencies, including isolated severe selective IgA deficiency, panhypogammaglobulinemia, and isolated combined IgA and IgM deficiency. There are only few reported ca...

Selective immunoglobulin A deficiency (IgAD) is the most common primary immunodeficiency in Caucasians. It has previously been suggested to be associated with a variety of concomitant autoimmune diseases. In this review, we present data on the prevalence of IgAD in patients with Graves disease (GD), systemic lupus erythematosus (SLE), type 1 diabetes (T1D), celiac disease (CD), myasthenia gravi...
