What is serum galactomannan?
Background: A serum galactomannan (GM) antigen test has been widely used to diagnose invasive pulmonary aspergillosis. However, there are limited data on the use of the serum GM antigen test for the serologic diagnosis of chronic pulmonary aspergillosis (CPA).
Is galactomannan specific to Aspergillus?
Galactomannan (GM) testing from BALF is well established in the diagnosis of pulmonary invasive aspergillosis (IPA) (Ullmann et al., 2018), but evidence about the performance in CPA patients is limited. Only four studies have reported GM test results from BALF in CPA patients so far.
Why is galactomannan important?
Galactomannan (GM) in the blood is a suitable biomarker for the diagnosis of IA in neutropenic patients. Highest test accuracy is obtained by two consecutive samples with an optical density (OD) index of ≥ 0.5.
What is the treatment for aspergillosis?
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 fungus grow in your lungs?
The mold spores can colonize (grow) inside lung cavities that developed as a result of chronic diseases, such tuberculosis, emphysema, or advanced sarcoidosis. The fibers of fungus might form a lump by combining with white blood cells and blood clots. This lump or ball of fungus is called an aspergilloma or mycetoma.
What is 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 is Aspergillus galactomannan test?
Clinical Significance. The aspergillus EIA test is an aid in the early diagnosis of invasive aspergillosis. In conjunction with other diagnostic tests and clinical signs of disease, it is an aid in the effective early treatment of disease. Methodology.
What is Aspergillus galactomannan antigen?
What is an Aspergilloma?
An aspergilloma is a fungus ball or mycetoma composed of Aspergillus hyphae along with cellular debris and mucus. It is a noninvasive type of chronic pulmonary aspergillosis. Aspergillus species colonize the preexisting cavity in the lung parenchyma and form a fungus cavity.
How do you get rid of Aspergillus mold?
Chlorine bleach: Sodium hypochlorite or regular household bleach works best to destroy mold and remove any discoloration. It is quite harsh and should be diluted before using.
