Common Mold Allergies – Aspergillus

There are hundreds of types of molds, but not all of them are responsible for causing allergy symptoms. The most common allergy-causing molds include:

Alternaria – Aspergillus – Cladosporium – Penicillium

Today MACTexas takes a closer look at Aspergillus and Allergies.

The mold that triggers the ailments, aspergillus, is all over the place — inside and outside. Most strains of this form are innocuous, yet a couple can cause genuine ailments when individuals with debilitated insusceptible frameworks, hidden lung ailment or asthma breathe in their contagious spores.

In certain individuals, the spores trigger a hypersensitive response. Others create gentle to genuine lung diseases. The most serious type of aspergillosis obtrusive aspergillosis happens when the disease spreads to veins and beyond.

The signs and symptoms of aspergillosis vary with the type of illness you develop:

Allergic reaction

Some people with asthma or cystic fibrosis have an allergic reaction to aspergillus mold. Signs and symptoms of this condition, known as allergic bronchopulmonary aspergillosis, include:

  • Fever
  • A cough that may bring up blood or plugs of mucus
  • Worsening asthma

Certain incessant lung (aspiratory) conditions, for example, emphysema, tuberculosis, or propelled sarcoidosis, can cause air spaces (holes) to frame in the lungs. At the point when individuals with lung cavities are likewise contaminated with aspergillus, organism strands may discover their way into the cavities and develop into tangled masses (parasite balls) known as aspergillomas.

Aspergillomas may create no manifestations or cause just a gentle hack from the start. After some time and without treatment, in any case, aspergillomas can intensify the basic incessant lung condition and conceivably cause:

  • A cough that often brings up blood (hemoptysis)
  • Wheezing
  • Shortness of breath
  • Unintentional weight loss
  • Fatigue

Invasive aspergillosis

This is the most extreme type of aspergillosis. It happens when the contamination spreads quickly from the lungs to the mind, heart, kidneys, or skin. Obtrusive aspergillosis happens just in individuals whose resistant frameworks are debilitated because of malignant growth chemotherapy, bone marrow transplantation or an infection of the invulnerable framework. Untreated, this type of aspergillosis might be lethal.

Signs and manifestations rely upon which organs are influenced, yet when all is said in done, obtrusive aspergillosis can cause:

  • Fever and chills
  • A cough that brings up blood (hemoptysis)
  • Shortness of breath
  • Chest or joint pain
  • Headaches or eye symptoms
  • Skin lesions

Other types of aspergillosis

Aspergillus can invade areas of your body other than your lungs, such as your sinuses. In your sinuses, the fungus can cause a stuffy nose sometimes accompanied by drainage that may contain blood. Fever, facial pain, and headache may also occur.

When to see a doctor

On the off chance that you have asthma or cystic fibrosis, see your primary care physician at whatever point you notice an adjustment in your relaxing. Even though aspergillosis may not be the reason, it is critical to have breathing issues assessed.

If you have a debilitated resistant framework and build up an unexplained fever, brevity of breath or a hack that raises blood, get prompt clinical consideration. Because of obtrusive aspergillosis, brief treatment is critical. Now and again, treatment with antifungal medicine starts when aspergillosis is suspected, even before testing has affirmed the analysis.

Aspergillus mold is unavoidable. Outdoors, it is found in decaying leaves and compost and on plants, trees, and grain crops.

Everyday exposure to aspergillus is rarely a problem for people with healthy immune systems. When mold spores are inhaled, immune system cells surround and destroy them. But people who have a weakened immune system from illness or immunosuppressant medications have fewer infection-fighting cells. This allows aspergillus to take hold, invading the lungs and, in the most serious cases, other parts of the body.

Aspergillosis is not contagious from person to person.

Risk factors

Your risk of developing aspergillosis depends on your overall health and the extent of your exposure to mold. In general, these factors make you more vulnerable to infection:

  • Weakened immune system. People taking immune-suppressing drugs after undergoing transplant surgery — especially bone marrow or stem cell transplants — or people who have certain cancers of the blood are at highest risk of invasive aspergillosis. People in the later stages of AIDS also may be at increased risk.
  • Low white blood cell level. People who have had chemotherapy, an organ transplant or leukemia have lower white cell levels, making them more susceptible to invasive aspergillosis. So, does having chronic granulomatous disease — an inherited disorder that affects immune system cells.
  • Lung cavities. People who have air spaces (cavities) in their lungs are at higher risk of developing aspergillomas.
  • Asthma or cystic fibrosis. People with asthma and cystic fibrosis, especially those whose lung problems are long-standing or hard to control, are more likely to have an allergic response to aspergillus mold.
  • Long-term corticosteroid therapy. Long-term use of corticosteroids may increase the risk of opportunistic infections, depending on the underlying disease being treated and what other drugs are being used.

Depending on the type of infection, aspergillosis can cause a variety of serious complications:

Bleeding. Both aspergillomas and invasive aspergillosis can cause severe, and sometimes fatal, bleeding in your lungs.

Systemic infection. The most serious complication of invasive aspergillosis is the spread of the infection to other parts of your body, especially your brain, heart, and kidneys. Invasive aspergillosis spreads rapidly and may be fatal.


It’s nearly impossible to avoid exposure to aspergillus, but if you have had a transplant or are undergoing chemotherapy, try to stay away from places where you’re likely to encounter mold, such as construction sites, compost piles and buildings that store grain. If you have a weakened immune system, your doctor may advise you to wear a face mask to avoid being exposed to aspergillus and other airborne infectious agents.
