People with CVID are also at an increased risk for certain cancers lymphoid and gastrointestinal cancers primarily. Treatment for CVID involves immunoglobulin replacement, preventative antibiotics, and if indicated management of autoimmune and granulomatous disease.

As with other antibody deficiencies, the most common types of recurrent infections involve the ears, sinuses, nose, bronchi and lungs.
These include:. In most cases the causes of CVID are not known. Studies have identified a small number of abnormal genes that are involved in immune cell development in around one in ten people with CVID. Antibodies, also known as immunoglobulins, are proteins made by specialised white blood cells, called B cells B lymphocytes.
Antibodies recognise germs so they can be removed by the rest of the immune system. For B cells to work effectively they usually need help from other immune cells such as the T cells T lymphocytes , which are another type of specialised white blood cell in the immune system.
People with CVID will vary in their ability to make effective antibody responses, due to decreased levels of:. Most people with CVID have frequent infections due to their reduced antibody responses. These infections usually occur in the ears, sinuses, nose and lungs. Other common infections in CVID include conjunctivitis, and persistent diarrhoea. Unusual infections may also occur, including meningitis and blood stream infection. Infections that are not treated properly in people with CVID, can result in damage to organs in the body, such as the sinuses, causing chronic sinusitis, or the airways of the lung bronchi , causing bronchiectasis.
This organ damage can lead to tissue damage, causing ongoing mucus secretion and the persistent need to clear phlegm sputum or thick white, yellow or green mucus from the nose. Once tissue damage is established, infection tends to become more persistent and difficult to clear.

Summary Summary. Symptoms Symptoms. The symptoms of common variable immunodeficiency CVID may be different from person to person.
Some people may be more severely affected than others, even people who have the same form. Not everyone with common variable immunodeficiency will have the same symptoms.

If you have CVID , you'll likely have repeated infections in your ears, sinuses and respiratory system. You'll also have an increased risk of digestive disorders, autoimmune disorders, blood disorders and cancer. CVID can be inherited, or you can develop it during your lifetime. The severity of symptoms can vary greatly between people with CVID.
Symptoms of common variable immunodeficiency may appear during childhood or adolescence, though many people don't experience them until adulthood. If you have CVID , you'll likely experience repeated infections before being diagnosed. The most common types of infections include pneumonia, sinusitis, ear infections and gastrointestinal infections.
In the vast majority of CVID cases, the cause is unknown.
