Normal numbers of B cells with isotype or light chain deficiencies: heavy chain deletions, kappa chain deficiency, isolated IgG subclass deficiency, IgA with IgG subclass deficiency, selective immunoglobulin A deficiency; Specific antibody deficiency to specific antigens with normal B cell and normal Ig concentrations
Primary immunodeficiencies are disorders in which part of the body's immune system is missing or does not function normally. [1] To be considered a primary immunodeficiency (PID), the immune deficiency must be inborn, not caused by secondary factors such as other disease, drug treatment, or environmental exposure to toxins.
Humoral immune deficiency (including B cell deficiency or dysfunction), with signs or symptoms depending on the cause, but generally include signs of hypogammaglobulinemia (decrease of one or more types of antibodies) with presentations including repeated mild respiratory infections, and/or agammaglobulinemia (lack of all or most antibody production) which results in frequent severe infections ...
Absent B cells with a resultant severe reduction of all types of antibody: X-linked agammaglobulinemia (btk deficiency, or Bruton's agammaglobulinemia), μ-Heavy chain deficiency, l 5 deficiency, Igα deficiency, BLNK deficiency, thymoma with immunodeficiency; B cells low but present, but with reduction in 2 or more isotypes (usually IgG & IgA ...
PLAID syndrome is an inherited condition characterised by antibody deficiency and immune dysregulation, first described in 2012. The name is an acronym of "PLCG2-associated antibody deficiency and immune dysregulation". It is characterised by cold-induced urticaria, autoimmunity, atopy and humoral immune deficiency. [1]
Nuclear factor-kappa B Essential Modulator (NEMO) deficiency syndrome is a rare type of primary immunodeficiency disease that has a highly variable set of symptoms and prognoses. It mainly affects the skin and immune system but has the potential to affect all parts of the body, including the lungs, urinary tract and gastrointestinal tract. [1]
Here, a catheter is inserted into the vein and a fluid, containing antibodies normally made by B-cells, is injected into the patient's body. [27] Antibodies, Y-shaped proteins created by plasma cells, recognize and neutralize any pathogens in the body. [28] However, the IVIG is expensive, in terms of time and finance. [29]
Serious, potentially fatal illnesses could arise from several of these bacterial diseases. Isolated primary immunoglobulin M deficiency can manifest clinically as recurrent otitis media, bronchiectasis, chronic sinusitis, bronchitis, urinary tract infections, respiratory infections, cellulitis, meningitis, and sepsis.
