Key Points • Replacement immune globulin, administered by intravenous or subcutaneous route, is indicated as replacement therapy in patients with antibody immunodeficiency disorders. • Dosing intravenous immune globulin (IVIG) to…
Key Points • Monogenic defects have been identified that interfere with self tolerance. • Human defects of self tolerance can affect both central and peripheral tolerance. • Linking specific genetic…
Key Points • In the majority of the autoinflammatory diseases innate immune system dysregulation is the cause of the inflammation. • Most of these conditions have a monogenic cause. •…
Key Points • Rheumatologic disorders are perpetuated by ongoing immune activation resulting from failure to clear triggering antigens combined with aberrant control mechanisms. • The resulting chronic inflammation leads to…
Key Points • White blood cells (lymphoid or myeloid) can suffer from quantitative or functional congenital disorders. • The type of cells or mechanisms that are mainly affected will define…
Key Points • A hallmark of allergic inflammation is the accumulation of a large number of leukocytes, including eosinophils, neutrophils, lymphocytes, basophils and macrophages, in the inflammatory tissues. • Leukocyte…
Key Points • IgE-producing B cells arise from IgM + or IgG + B cells via the process of class switch recombination (CSR). B cells undergoing CSR undergo somatic gene…
Key Points • SLE and neisserial infections are the common complement deficiency phenotypes seen in Allergy Immunology practices. • CH50 and AH50 assays represent logical initial studies to diagnose many…
Key Points • Defects of T cell development and/or function cause increased susceptibility to infections of bacterial, viral and fungal origin, and are often associated with autoimmune manifestations and malignancies….
Key Points • A clinician must maintain an index of suspicion for immunodeficiency when confronted with patients with infections considered unusual with respect to frequency, severity, response to treatment, or…
