Common variable immunodeficiency disorder (CVID) is a primary immunodeficiency disorder that affects the immune system’s ability to fight off infections. Here’s what you need to know about CVID, including its causes, symptoms, diagnosis, and treatment.
Individuals with CVID have low levels of immunoglobulins, which are proteins that help fight infections, making them more susceptible to infections.
The symptoms of CVID vary, but may include recurrent infections such as sinus, lung, and ear infections, as well as gastrointestinal and skin infections. Some individuals with CVID may also experience autoimmune disorders, which occur when the immune system attacks healthy tissues in the body.
CVID is diagnosed through blood tests to measure immunoglobulin levels and determine if they are low. CVID is caused by genetic mutations, and environmental factors may also play a role.
Treatment for CVID typically involves immunoglobulin replacement therapy, which replaces the missing antibodies and helps prevent infections. Antibiotics and other medications may also be used to treat infections and manage symptoms.
If you experience recurrent infections or other symptoms of CVID, talk to your doctor about testing and treatment options.
