Presentation
IgA present in these secretions is also termed secretory IgA. [scidcompass.org]
Deficiencies of IgG present variably according to subclass. IgG deficiencies are typically relative among subclasses and not absolute. Thus even with a given selective IgG subclass deficiency, total IgG levels may still fall within normal range. [tititudorancea.com]
They rarely present with severe reactions, including anaphylaxis, to blood transfusions or intravenous immunoglobulin due to the presence of IgA in these blood products. [en.wikipedia.org]
IgD IgD antibodies may be present on the surface of B cells, but their function is not fully understood at this time. IgE IgE antibodies are normally present in trace amounts and are important in allergic reactions. [myigsource.com]
Whereas the antigen-presenting function of DCs has been reported to be normal in CVID [7, 8], their involvement in the origin of some CVID cannot be ruled out, as these cells are known to interact directly with B cells, to present antigen to T cells, [arthritis-research.biomedcentral.com]
Entire Body System
- Falling
Thus even with a given selective IgG subclass deficiency, total IgG levels may still fall within normal range. The clinical course and prognosis is dependent upon the severity of the deficiency and associated morbidity. [tititudorancea.com]
IgG levels fall in the first 6 months of life as maternal transplacentally acquired antibody level falls (normal physiological hypogammaglobulinaemia). Premature infants have less maternal IgG and may reach a lower nadir. [racgp.org.au]
The patient and all household members should receive the influenza (flu) vaccine every fall. A new 7-valent pneumococcal conjugate vaccine has just been licensed. [atcp.org]
Baby teeth also may not fall out to make room for the adult set of teeth. Hyper IgE Syndrome can be autosomal dominant (AD) or autosomal recessive (AR). The condition is estimated to affect less than 1 in a million people. [immunodeficiency.ca]
- Recurrent Respiratory Infections
Patient and method: A 13 year-old male patient diagnosed with selective IgA deficiency presenting with recurrent respiratory infections, allergic asthma, allergic rhinitis, gastrointestinal disturbances and epilepsy has been followed up at our hospital [bib.irb.hr]
Individuals with any IgG subclass deficiency occasionally have recurrent respiratory infections, primarily Streptococcus pneumoniae and Haemophilus Influenzae. [immunodeficiency.ca]
Skin
- Hypopigmented Skin
Griscelli Syndrome Griscelli syndrome (GS) is a rare autosomal recessive disorder that results in hypopigmented (unusually light) skin and silvery hair. [immunodeficiency.ca]
Neurologic
- Irritability
IPEX also results in autoimmune conditions related to the intestines and the skin, resulting in chronic diarrhea, failure to gain weight, rashes and skin irritation. IPEX is an X-linked disease, so only males are affected. [immunodeficiency.ca]
Workup
[…] deficiency have a tendency to develop recurrent sinopulmonary infections, gastrointestinal infections and disorders, allergies, autoimmune conditions, and malignancies.[2] These infections are generally mild and would not usually lead to an in-depth workup [en.wikipedia.org]
Serum
- Cytopenia
These patients have hypogammaglobulinaemia (low IgG with low IgA and/or IgM), poor specific antibody responses to vaccinations, and an increased incidence of autoimmune disease, particularly autoimmune cytopenias due to dysregulation of the immune response [racgp.org.au]
Microbiology
- Candida
CMC is hereditary and presents itself soon after birth with frequent cases of oral candida (thrush). CMC occurs because of an individual's selective T-cell deficiency to Candida and related fungi. [immunodeficiency.ca]

Treatment
[citation needed] Treatment[edit] The treatment consists of identification of co-morbid conditions, preventive measures to reduce the risk of infection, and prompt and effective treatment of infections. [en.wikipedia.org]
Treatment of the allergies associated with IgA deficiency is similar to treatment of allergies in general. [scidcompass.org]
The treatment for the condition involves immunoglobulin replacement and granulocyte growth factor. [immunodeficiency.ca]
The HAART-receiving, HIV load-positive group was a mixed population that included patients who were not treatment compliant and those who were in the early stages of treatment, before their HIV load was under control. [academic.oup.com]

Pathophysiology
Selective IgA deficiency is often inherited, but has been associated with some congenital intrauterine infections.[4] Pathophysiology[edit] Pathogenesis of IgA Deficiency ‘In IgA-deficient patients, the common finding is a maturation defect in B cells [en.wikipedia.org]
Pathophysiology Genetic rearrangements occur during the maturation of B lymphocytes, eventually resulting in the surface expression of both immunoglobulin M (IgM) and IgD on mature B cells. Cell signaling occurs through this surface IgD. [emedicine.medscape.com]
Although the pathophysiology of CVID is heterogeneous and largely unknown, several causes leading to an alteration of immunoglobulin concentrations in the blood have already been identified. [arthritis-research.biomedcentral.com]
To fully understand the role of Tregs in the pathophysiology of diseases and defects one needs to look both at the natural Tregs (nTregs), induced Tregs (iTregs), and their function. nTregs were measured in PBMCs stimulated in vitro for 4 h with PMA and [frontiersin.org]
Prevention
This alert generally prevents other cells from becoming infected. Unfortunately, many viruses can outsmart this protective strategy, and they continue to spread the infection. [primaryimmune.org]
Certain patients who have chronic sinusitis or chronic bronchitis may need to stay on long-term preventive antibiotic therapy (antibiotic prophylaxis). [scidcompass.org]
[citation needed] Treatment[edit] The treatment consists of identification of co-morbid conditions, preventive measures to reduce the risk of infection, and prompt and effective treatment of infections. [en.wikipedia.org]
It is also determined by measuring the blood level of IgG in the patient at some interval after infusion, and by determining how well a given dose of gamma globulin is treating or preventing symptoms. [atcp.org]
Normally, these cells recognize and attack foreign invaders, such as viruses and bacteria, to prevent infection. [immunodeficiency.ca]
