Common Variable Immune Deficiency

Community, Stories & Info

Common Variable Immune Deficiency (CVID) is a condition characterized by low levels of serum immunoglobulins and antibodies, creating an increased susceptibility to infection. It is classified as a primary immunodeficiency (PI). Symptoms vary from mild to severe and may include recurring bacterial infections (especially in the upper and lower respiratory tracts), gastrointestinal complications, abdominal pain, bloating, nausea, weight loss and vomiting. Patients may develop chronic lung disease and experience serious medical complications as a result. Treatment for CVID depends on the severity of the patient’s individual case but typically involves the coordinated effort of a team of specialists, immunoglobulin therapy and medication. Organizations exist to provide support to people experiencing rare health conditions in their lives.
