What is the most common immunodeficiency?
In the United States, common variable immunodeficiency is the most frequently diagnosed primary immunodeficiency. The term “common variable immunodeficiency” encompasses a heterogeneous group of disorders that cause hypogammaglobulinemia (serum IgA levels below 5 mg per dL [0.05 g per L]).
How common is common variable immune deficiency?
CVID equally affects males and females. The prevalence of CVID is approximately 1 in 30,000 people. The diagnosis of CVID is not made in children under the age of 4, because until that time, it may be confused with other genetic defects that must be excluded.
What is the life expectancy of someone with CVID?
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.
What are the common symptoms of CVID?
