Background: A serum galactomannan (GM) antigen test has been widely used to diagnose invasive pulmonary aspergillosis.

What does a positive galactomannan mean?

A positive result supports a diagnosis of invasive aspergillosis (IA). Positive results should be considered in conjunction with other diagnostic procedures, such as microbiologic culture, histological examination of biopsy specimens, and radiographic evidence.

What is the normal range for galactomannan?

What is a galactomannan antigen?

Galactomannan (GM) is a polysaccharide antigen that exists primarily in the cell walls of Aspergillus species. GM may be released into the blood and other body fluids even in the early stages of Aspergillus invasion, and the presence of this antigen can be sustained for 1 to 8 weeks (9).

What does Abpa stand for?

Allergic bronchopulmonary aspergillosis (called ABPA for short) is a problem in the lungs that is not very common. It is caused by a severe allergic reaction after being exposed to a type of fungus called Aspergillus. Common signs and symptoms of ABPA. A person with ABPA will have some or all of the.

What is the treatment for Aspergillus?

Antifungal medications. These drugs are the standard treatment for invasive pulmonary aspergillosis. The most effective treatment is a newer antifungal drug, voriconazole (Vfend). Amphotericin B is another option. All antifungal drugs can have serious side effects, including kidney and liver damage.

Can Aspergillus Galactomannan be life threatening?

Invasive aspergillosis (IA) is a potentially life-threatening disease, occurring mostly in severely immunocompromised patients such as those with acute myeloid leukemia, those with prolonged neutropenia due to myelotoxic therapy, or following allogeneic hematopoietic cell transplantation or solid organ transplantation.

What are the symptoms of aspergillosis?

The symptoms of allergic bronchopulmonary aspergillosis (ABPA) are similar to asthma symptoms, including: Wheezing. Shortness of breath. Cough….Symptoms of chronic pulmonary aspergillosis4,5 include:

• Weight loss.
• Cough.
• Coughing up blood.
• Fatigue.
• Shortness of breath.

How is invasive aspergillosis diagnosed?

Imaging test. A chest X-ray or computerized tomography (CT) scan — a type of X-ray that produces more-detailed images than conventional X-rays do — can usually reveal a fungal mass (aspergilloma), as well as characteristic signs of invasive aspergillosis and allergic bronchopulmonary aspergillosis.

Is lung fungal infection curable?

Fungus balls in the lungs (aspergillomas) usually do not require treatment with drugs and do not usually respond to drugs. If these balls cause bleeding (causing people to cough up blood) or other symptoms, they may need to be removed surgically.
