How does someone get common variable immunodeficiency?
A genetic mutation (change) causes CVID. In most cases, this genetic mutation — and CVID symptoms — develop without any apparent cause. In about 10 percent of cases, CVID is hereditary (passed down among family members). CVID results from defects in the genes involved with the immune system.
Is common variable immune deficiency a rare disease?
CVID is the most common of all the primary immunodeficiency rare diseases. It is found in about one in 25,000 people. It is most often diagnosed in adults. Only about 20% of those affected with this disorder are diagnosed as children.
What does common variable immunodeficiency mean?
Common variable immunodeficiency (CVID) is a primary immune deficiency disease characterized by low levels of protective antibodies and an increased risk of infections. Although the disease usually is diagnosed in adults, it also can occur in children.
What are the most common form of immune deficiencies?
Common primary immunodeficiencies include disorders of humoral immunity (affecting B-cell differentiation or antibody production), T-cell defects and combined B- and T-cell defects, phagocytic disorders, and complement deficiencies.
How long do people live with common variable immunodeficiency?
The life expectancy of CVID patients has considerably improved over the past 30 years [5, 63], from initially 12 years to currently over 50 years [3]. Reduced survival was significantly associated with age at diagnosis, lower baseline IgG, higher IgM and fewer peripheral B cells.
Can you live a normal life with CVID?
It's possible to live a full and active life with CVID, but it will take some adjustments. These include regular treatment with immunoglobulin replacement therapy, as well as lifestyle modifications to prevent infections.
What does CVID do to the body?
Description. Common variable immune deficiency (CVID) is a disorder that impairs the immune system. People with CVID are highly susceptible to infection from foreign invaders such as bacteria, or more rarely, viruses and often develop recurrent infections, particularly in the lungs , sinuses , and ears .
Is CVID serious?
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.
What is the treatment for CVID?
Treatments for CVID focus on decreasing the frequency and the severity of your infections and may include immunoglobulin and antibiotic therapies. Doctors trained in pediatric immunodeficiency disorders care for children with CVID and other immune system disorders at Mayo Clinic Children's Center.
How do you test for common variable immunodeficiency?
The diagnosis of CVID is primarily established by testing for low blood (serum) IgG immunoglobulin concentrations ranging from severely reduced (<100 mg/dL) to just below adult normal range (500-1200 mg/dL). In addition, laboratory testing may reveal normal or, in some cases, reduced numbers of circulating B cells.
Why are CVID patients called zebras?
You may be wondering why your friend or family member living with primary immunodeficiency disease (PI) calls themselves a zebra, wears zebra print clothing and says things like, “zebra strong!” This is because the PI community often strongly identifies with zebras based on an old saying that doctors learn in medical ...
Does common variable immune deficiency cause pain?
CVID can be associated with autoimmune disorders that affect other blood cells causing low numbers of white cells or platelets, anemia, arthritis and other conditions such as endocrine disorders. Gastrointestinal problems including chronic diarrhea, weight loss, nausea, vomiting and abdominal pain can also be present.
How common is common variable immunodeficiency?
Frequency. CVID is estimated to affect 1 in 25,000 to 1 in 50,000 people worldwide, although the prevalence can vary across different populations.
How serious is CVID?
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.
Does common variable immunodeficiency qualify for disability?
The Social Security Administration lists immune deficiency disorders under qualifying impairments in the SSA's Blue Book. If you are disabled because of an immune deficiency disorder, you may qualify for Social Security benefits (SSDI).
Is CVID inherited?
The cause of CVID is unknown for most patients but a genetic cause has been identified in about 20%. Autosomal dominant (mostly) and autosomal recessive inheritance has been reported in CVID.
