Fortunately, with proper medical care, many patients live full and independent lives.Ī number of the more rare primary immune deficiencies are diagnosed in early childhood and result in shortened lives with extreme susceptibility to infection and malignancy. People with primary immune deficiencies often develop serious and debilitating illnesses. The increased vulnerability to infection may result in repeated infections, infections that won’t clear up or unusually severe infections. Those infections commonly involve skin, sinuses, throat, ears, lungs, brain, spinal cord, urinary tract and intestinal tract. Because a normal immune system protects the body against infection, patients with primary immune deficiencies are more susceptible to infections of all kinds.

The most apparent sign of an immune deficiency is frequent illness. Immune deficiency is a state in which the immune system’s ability to fight infection is compromised or entirely absent. Secondary immune deficiencies can be caused by exposure to radiation or toxic chemicals, chemotherapy, malnutrition and burns. When the damage is caused by an environmental agent, the resulting disease is referred to as secondary immune deficiency disease. Primary immune deficiency disease affect many thousands of children and adults in the U.S. According to the World Health Organization, there are more than 200 of these sometimes life-altering or life-threatening inherited defects – some are relatively rare, some are quite common. In the case of an inherited defect, the resulting disease is referred to as primary immune deficiency disease. An immune deficiency disease may be caused either by an inherited defect in the cells of the immune system or by an environmental agent.
