Hematopoietic stem cell transplantation using bone marrow, umbilical cord blood, or adult peripheral blood stem cells is effective for lethal T-cell and other immunodeficiencies. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. IgG antibody titers can be assessed in immunized patients by measuring antibody titers before and after administration of vaccine antigens (Haemophilus influenzae type B, tetanus, diphtheria, conjugated or nonconjugated pneumococcal, and meningococcal antigens); a less-than-twofold increase in titer at 2 to 3 weeks suggests antibody deficiency regardless of Ig levels. A similar test (AH50) can be done to detect complement deficiencies in the alternative pathway. All patients except infants < 6 months and people with blood type AB have natural antibodies at a titer of ≥ 1:8 (anti-A) or ≥ 1:4 (anti-B). Complications caused by a primary immunodeficiency disorder vary, depending on what type you have. 0000005618 00000 n Lack of response does not confirm immunodeficiency in patients with no previous exposure to Candida. Assays for oxidant products (hydrogen peroxide, superoxide) or proteins (CR3 [CD11] adhesive glycoproteins, NADPH oxidase components), History of staphylococcal abscesses or certain gram-negative or fungal infections (eg, Serratia marcescens, aspergillosis). Lymphopenia (lymphocytes < 2000/mcL [2.0 X 109/L] at birth, < 4500/mcL [4.5 x 109/L] at age 9 months, or < 1000/mcL [1.0 X 109/L] in older children or adults) suggests a T-cell disorder because 70% of circulating lymphocytes are T cells. Background . Chronic mucocutaneous candidiasis, a hereditary immunodeficiency disorder, is persistent or recurring infection with Candida (a fungus) due to malfunction of T cells (lymphocytes). Patients with immunodeficiency may or may not appear chronically ill. Macular rashes, vesicles, pyoderma, eczema, petechiae, alopecia, or telangiectasia may be evident. 0 Select additional tests based on what type of immune defect is suspected (humoral, cellular, phagocytic cell, or complement). The presentation of hyper IgE syndrome is highly variable, which makes it easy to confuse the diagnosis with that of severe atopy or other rare immunodeficiency … Primary immunodeficiency disorders are an uncommon cause of recurrent respiratory infections in children, but are thought to be underdiagnosed. Immunodeficiency should also be suspected in infants or young children with chronic diarrhea and failure to thrive, especially when the diarrhea is caused by unusual viruses (eg, adenovirus) or fungi (eg, Cryptosporidium). Age when recurrent infections began is important: Onset before age 6 months suggests a T-cell defect because maternal antibodies are usually protective for the first 6 to 9 months. 0000003448 00000 n Tests are needed to confirm a diagnosis of immunodeficiency (see table Initial and Additional Laboratory Tests for Immunodeficiency). Common variable immunodeficiency (CVID) is a heterogeneous syndrome, presenting with low IgG levels and no association with drugs or diseases known to cause secondary antibody deficiency.
