The precise symptoms of a primary immunodeficiency depend on the type of defect. Generally, the symptoms and signs that lead to the diagnosis of an immunodeficiency include recurrent or persistent infections or developmental delay as a result of infection. Particular organ problems (e.g. diseases involving the skin, heart, facial development ...
In certain conditions, the regulation rather than the intrinsic activity of parts of the immune system is the predominant problem. [7] Immunodeficiency with hypopigmentation or albinism: Chédiak–Higashi syndrome, Griscelli syndrome type 2; Familial hemophagocytic lymphohistiocytosis: perforin deficiency, UNC13D deficiency, syntaxin 11 deficiency
Secondary or acquired immune deficiencies are caused by something outside the body such as a virus or immune suppressing drugs. [6] Primary immune diseases are at risk to an increased susceptibility to, and often recurrent ear infections, pneumonia, bronchitis, sinusitis or skin infections. Immunodeficient patients may less frequently develop ...
Primary Immunodeficiency is also known as congenital immunodeficiencies. [11] Many of these disorders are hereditary and are autosomal recessive or X-linked. There are over 95 recognised primary immunodeficiency syndromes; they are generally grouped by the part of the immune system that is malfunctioning, such as lymphocytes or granulocytes. [12]

Immunology is a branch of biology and medicine [1] that covers the study of immune systems [2] in all organisms.. Immunology charts, measures, and contextualizes the physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, [3] immune deficiency, [4] and ...
PI3kinase. The pathophysiology of activated PI3K delta syndrome has several aspects. [2] The normal function has P110δ (PI3K) involved in immune system regulation. [9]P110δ effect is not limited to the immune system; P110δ has a presence in transformed epithelial cells and cell adhesion molecules (airway inflammation), and research has been done on the possibility of P110δ in the nervous ...
Selective immunoglobulin A deficiency, Selective IgE deficiency disease, IgG deficiency, and Isolated primary immunoglobulin M deficiency. Dysgammaglobulinemia is a type of immune disorder characterized by a reduction in some types of gamma globulins , resulting in heightened susceptibility to some infectious diseases where primary immunity is ...
