Partial Combined Immunodeficiency (PCID)

Partial Combined immunodeficiency Disorder Definition An immune disorder in which the immune system is missing key components. Most often people who have PCID lack certain leukocytes (white blood cells), which impairs their ability to form antibodies (develop immunity) and fight infection. The abnormality might be with cell differentiation, maturity, or function. Sometimes PCID involves deficits of complement […]

Severe Combined Immunodeficiency Disease (SCID)

Severe Combined Immunodeficiency Disease Definition A rare, genetic immune disorder in which an infant is born with severely deficient immune capability due to the absence of leukocytes. Because the infant receives passive immunity from his or her mother at birth (and through breastfeeding), the deficiency often is not apparent until age three to six months or […]
