2 Examples of Mycoses Aspergillosis Aspergillosis is the name of a range of infections caused by a fungal mould called aspergillus. It usually affects the lungs, but it can spread to almost anywhere in the body. Aspergillosis usually only affects people with existing health conditions. Most healthy people have natural immunity to the aspergillus mould. If someone with damaged lungs or a weakened immune system breathes in aspergillus spores, the infection is more likely to stay.

3 Types of aspergillosis There are several forms of aspergillosis : allergic bronchopulmonary aspergillosis aspergilloma invasive pulmonary aspergillosis Dalia

4 is caused by an allergic reaction to spores of fungus mould. It is the mildest form of aspergillosis. ABPA usually affects people with asthma or cystic fibrosis. It is estimated to affect 0.25–0.8% of people with mild to moderate asthma, and 7% of people with cystic fibrosis.asthmacystic fibrosis ABPA affects an estimated 7–10% of people with more severe asthma that can only be controlled with steroid medication.

8 Aspergilloma Aspergilloma is common in people who have cystic fibrosis or cavities (spaces) in their lungs. Coughing up blood is one of the most common symptoms of aspergilloma. Aspergillus fungi enter the lungs and group together to form a dense knot of fungi, called a fungal ball. Aspergilloma usually only affects people who have an existing lung condition, such as tuberculosis (TB), which means that they have cavities or damage in their lungs. tuberculosis Dalia

12 Invasive pulmonary aspergillosis (IPA) IPA is a fungal infection in the lungs that spreads rapidly through the body. The infection can spread to the blood, brain, heart and kidneys. IPA usually only affects people with a severely weakened immune system, such as: people with end-stage HIVHIV people undergoing high-dose chemotherapy people taking immunosuppressants because they have had an organ or bone marrow transplant Dalia

25 Treatments How is aspergillosis treated? Allergic bronchopulmonary aspergillosis (ABPA) is usually treated with steroid medications to prevent an allergic response. However, if ABPA reoccurs, a long-term course of steroids may be required. -aspergilloma can be treated with antifungal medications. In some cases, surgery may be required to remove the infection from the lungs. -Invasive pulmonary aspergillosis (IPA) can be treated with antifungal medication, although it is difficult to treat. The infection can spread very quickly, and someone who develops IPA is usually already very ill. An estimated 50% of people do not respond to treatment and die from the condition Dalia…
