Evolution of IgA deficiency to IgG subclass deficiency and common variable immunodeficiency.
FIRST REPORT: male child with repeated pulmonary infections from the age of 4 months. He was diagnosed as IgA deficiency (undetectable IgA levels) at the age of 3 years, when he presented repeated bouts of pneumonia and tonsillitis. Several immunologic evaluations were made between the ages of 4 months and 8 years. At 8 years and 9 months, the diagnosis of IgA deficiency was confirmed, and asso...
متن کاملProgression of selective IgA deficiency to common variable immunodeficiency.
Selective IgA deficiency (IgAD) is the most common primary immunodeficiency in Caucasians. Although it is often asymptomatic, selected patients show an increased frequency of infections, allergies and autoimmune manifestations. Common variable immunodeficiency (CVID) is a primary antibody deficiency disease that shares many clinical features with IgAD. A common genetic basis for IgAD and CVID h...
متن کاملCommon variable immunodeficiency.
We describe a patient with common variable immunodeficiency who three times presented an anaphylactic reaction after intravenous immunoglobulin administration. These reactions were attributed to the total absence of IgG 2, 3 and 4.
متن کاملCommon variable immunodeficiency.
Common variable immunodeficiency (CVID) is a form of severe antibody deficiency with an estimated prevalence of 1 in 25,000 to 1 in 100,000. The disorder apparently results from currently undefined immune deregulations resulting in failed B-cell differentiation with impaired secretion of immunoglobulins. A 5-year female presented with fever, cough and shortness of breath at rest. Past medical h...
متن کاملCommon variable immunodeficiency
Common variable immunodeficiency (CVID) is a common primary immunodeficiency characterized by a failure in B-cell differentiation with defective immunoglobulin production. Affected patients are uniquely susceptible to recurrent infection with encapsulated organisms and have an increased propensity for the development of inflammatory and autoimmune manifestations. The diagnosis of CVID is common...
