Common Variable Immunodeficiency
Heterogeneous group of immunodeficiency syndromes characterized by hypogammaglobulinemia of most isotypes, variable B-cell defects, and the presence of recurrent bacterial infections.
About the D83 Code Range
Common variable immunodeficiency is a group of immune disorders marked by low levels of most antibody types, differing B-cell defects, and recurring bacterial infections.
The subdivisions distinguish predominant problems with B-cell numbers and function (D83.0) from disorders of T-cells that regulate immune activity (D83.1). D83.2 identifies antibodies against B-cells or T-cells. D83.8 covers other forms, while D83.9 is unspecified.
