Jan 06, 2022 · Medications Medications to treat XLA include: Gammaglobulin. This is a type of protein found in blood that contains antibodies against infections. It's given by infusion into a vein every two to four weeks or by weekly injection. Reactions to gammaglobulin can include headache, chills, backache and nausea.
Therapy
There is no cure for XLA, but the condition can be successfully treated. Immunoglobulin replacement therapy is a life-long and life-saving treatment that restores some of the missing antibodies. In addition, some people benefit from a daily course of oral antibiotics to prevent or treat infections.

Introduction: X-linked agammaglobulinemia (XLA) is the most common primary immunodeficiency in man, and is caused by a single genetic defect. Inactivating mutations in the Bruton's tyrosine kinase (BTK) gene are invariably the cause of XLA,. XLA is characterized by a differentiation arrest at the pre-B cell stage, the absence of immunoglobulins ...

How often should I see my doctor if I have XLA?

What causes XLA?
XLA is an inherited immune disorder caused by an inability to produce B cells or the immunoglobulins (antibodies) that the B cells make. XLA is also called Bruton type agammaglobulinemia, X-linked infantile agammaglobulinemia, and congenital agammaglobulinemia.

Preventing bacterial infections is very important for people with XLA. Gammaglobulin (a type of protein in the blood that contains antibodies to prevent or fight infections) is the main treatment for people with XLA. In the past, most people received this by intravenous (IV) infusion every two to four weeks.
How is XLA diagnosed?
The diagnosis of XLA can be confirmed by demonstrating the absence of BTK protein in monocytes or platelets or by the detection of a mutation in BTK in DNA. Almost every family has a different mutation in BTK; however, members of the same family usually have the same mutation.
How common is XLA?
XLA is deemed to have a relatively low incidence of disease, with an occurrence rate of approximately 1 in 200,000 live births and a frequency of about 1 in 100,000 male newborns. It has no ethnic predisposition. XLA is treated by infusion of human antibody.
What causes agammaglobulinemia?
It is caused by a gene defect that blocks the growth of normal, mature immune cells called B lymphocytes. As a result, the body makes very little (if any) immunoglobulins. Immunoglobulins play a major role in the immune response, which protects against illness and infection.Feb 2, 2020

X-Linked agammaglobulinemia (XLA) is an inherited immunodeficiency in which the body is unable to produce the antibodies needed to defend against bacteria and viruses.
Why do XLA patients not have tonsils?
Doctors may find that people with XLA have very small tonsils and lymph nodes (glands of the neck). This is because tonsils and lymph nodes are made up of B lymphocytes. In people with XLA, the size of these tissues are reduced because of the absence of B lymphocytes.
What does XLA mean?
X-linked agammaglobulinemia (XLA) is a condition that affects the immune system and occurs almost exclusively in males. People with XLA have very few B cells, which are specialized white blood cells that help protect the body against infection.
What is XLA in medicine?
Listen. Managing X-linked agammaglobulinemia (XLA) mainly consists of preventing infections and treating infections aggressively when they do occur. Sudden infections in individuals with XLA are usually treated with antibiotics that are taken for at least twice as long as taken in healthy individuals. Preventing bacterial infections is very ...
What is X-linked agammaglobulinema?
X-linked agammaglobulinema is a primary immunodeficiency characterized by very low levels of immunoglobulins ( proteins made by the immune system to help fight infections). People affected by this condition generally begin developing frequent and recurrent bacterial infections from about 6 months of age. Commonly diagnosed infections include lung infections (pneumonia and bronchitis), middle ear infections, conjunctivitis, sinus infections, various skin infections, and infections that are associated with chronic diarrhea. [1] [2] [3] X-linked agammaglobulinemia is caused by changes ( mutations) in the BTK gene and is inherited in an X-linked recessive manner. [2] [3] Treatment aims to boost the immune system, which may be accomplished by administering immunoglobulins through a vein (IVIG) or subcutaneously (SCIG). Frequent infections are generally treated with antibiotics. [1] [2]

What do doctors look for in a diagnosis?
Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis.

The most common bacteria causing infection in XLA are Streptococcus, Staphylococcus and Haemophilus. Keep pace with the latest information and connect with others. Join us on Facebook. Symptoms.
How long does an infant's IgG last?

What is XLA in biology?
Description. X-linked agammaglobulinemia ( XLA) is a condition that affects the immune system and occurs almost exclusively in males. People with XLA have very few B cells, which are specialized white blood cells that help protect the body against infection. B cells can mature into the cells that produce special proteins called antibodies ...
Where is the Expand Section gene located?
Expand Section. This condition is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition.
Why is the BTK gene important?
This gene provides instructions for making the BTK protein, which is important for the development of B cells and normal functioning of the immune system . Most mutations in the BTK gene prevent the production of any BTK protein. The absence of functional BTK protein blocks B cell development and leads to a lack of antibodies.
What are the proteins that B cells produce?
B cells can mature into the cells that produce special proteins called antibodies or immunoglobulins. Antibodies attach to specific foreign particles and germs, marking them for destruction. Individuals with XLA are more susceptible to infections because their body makes very few antibodies.
Why are males affected by X-linked recessive disorders more frequently than females?
Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.
Can XLA cause diarrhea?
Infections that cause chronic diarrhea are also common. Recurrent infections can lead to organ damage. People with XLA can develop severe, life-threatening bacterial infections; however, affected individuals are not particularly vulnerable to infections caused by viruses.
Can XLA cause a sinus infection?
In children with XLA, infections generally take longer to get better and then they come back again, even with antibiotic medications. The most common bacterial infections that occur in people with XLA are lung infections (pneumonia and bronchitis), ear infections (otitis), pink eye (conjunctivitis), and sinus infections (sinusitis).
Is multivitamin used in XLA?
Nutritional intervention or supplementation and the use of multivitamin and mineral preparations are usually unnecessary in XLA, although some patients with autoimmune colitis occasionally require such therapy. Determining the etiology of the diarrhea (often infectious) is more important.
Is trimethoprim a first line antibiotic?
Trimethoprim-sulfamethoxazole is the first-line drug for both. Recently released antibiotics such as linezolid for penicillin-resistant pneumococci are presumably effective, although results in primary immunodeficiency diseases are not yet published. Many infections require interventions in addition to antibiotics.
Can antibiotics be used for bronchiectasis?
Some clinicians advocate rotating the use of antibiotics in select patients with bronchiectasis and frequent exacerbations.
Is ceftriaxone used for pneumonia?
Intravenous ceftriaxone may be required for chronic pulmonary infection, acute severe pneumonia, or sepsis. As with other patient populations, the risk for penicillin-resistance among S pneumoniae is an increasing concern; ceftriaxone, cefotaxime, and vancomycin are used to treat penicillin-resistant organisms.
