Aspergillus is a fungus found everywhere. It often affects people with weak immune systems or lung problems. Different Aspergillus types causeinfections. The three main types are allergic, chronic, and invasiveaspergillosis. In people with weakened immunity, the infection may start in sinuses. Without treatment, invasive aspergillosis can be deadly – mortality rate up to 100%. When suspected, thorough diagnosis is needed. Treatment should start quickly to prevent serious outcomes.
Epidemiology
Invasive aspergillosis often strikes those with weakened defenses. AIDS patients, transplant survivors taking anti-rejection medicine, folks with low white cell counts, corticosteroid users – all vulnerable. 10% to 20% of bone marrow recipients get aspergillosis. ICU respiratory cases like COPD, asthma – also at risk. Over 13 years, invasive aspergillosis quadrupled. Lung issues heighten risk for chronic aspergillosis: tuberculosis, COPD, lung cancer, sarcoidosis, asthma. Nearly all allergic bronchopulmonary aspergillosis hits cystic fibrosis, asthma patients. Agriculture, construction workers face greater exposure to Aspergillus fungus. Marijuana smokers too – contaminated marijuana carries aspergillosis threat.
Anatomy
Pathophysiology
Aspergillus conidia enter healthy lungs, where phagocytes absorb them. Inside, the conidia become hyphae at body temperature. The phagocytes release beta-D-glucan, activating neutrophils which kill invasive hyphae, stopping infection spread. However, immunocompromised patients may lack at least one defense mechanism, allowing unchecked infection throughout the body.
For those with weakened immunity, aspergillus can spread uncontrolled. A key defense is missing, allowing the fungus to grow and invade tissues without being destroyed by the immune system’s normal response.
Etiology
Usually, infections begin in the respiratory system. But Aspergillus can invade other body parts like the brain, skin, nails, eyes, sinuses, or spread throughout the body. Of all Aspergillus species, A. fumigatus causes most human infections. A. flavus often causes sinus infections. When the exact species can’t be identified, it’s labeled an Aspergillus species.
Genetics
Prognostic Factors
Patients with minor breathing issues often get better in Allergic Bronchopulmonary Aspergillosis (ABPA). Delays spotting it mean long steroid treatment, though. Invasive aspergillosis is deadly, with many deaths despite top medicines. Those with weak immunity face higher death risks. Even treated patients can get it again. If it spreads to the brain, it’salmost always fatal. The high aspergillosis death rate links to drug resistance growing.
Clinical History
Aspergillosis often targets those with weakened immunity. This includes chemotherapy patients, organ recipients, HIV/AIDS sufferers. Those with blood cancers, extreme low white counts face highest risk. Usual signs are fever, cough, chest pain, breathing woes, bloody cough in dire cases. Allergic bronchopulmonary aspergillosis frequently strikes asthmatic teens, adults, cystic fibrosis, bronchiectasis sufferers. Expect asthma flares, brown phlegm coughing, weight drop, fatigue. Aspergilloma can strike various aged folk, mainly bronchiectasis, previous TB adults. Symptoms may be cough, bloody cough, chest pain, weight loss, sometimes no symptoms appear.
Physical Examination
Respiratory examination is key for invasive aspergillosis. Listen for crackles, wheezing, decreased breath sounds, and check for distress. Inspect skin for lesions or nodules, if the infection spreads. If eyes are involved, look for pain, redness, vision issues, or retinal lesions. Asthma often brings wheezing and crackles with allergic bronchopulmonary aspergillosis (ABPA). Skin changes or dermatitis may also appear. Check eyes if symptoms develop. People with lung damage like tuberculosis may cough, cough up blood, and feel chest pain due to aspergillomas, fungal masses in lung cavities. Careful examination is crucial for proper diagnosis and treatment.
Aspergillosis is treated with antifungals first. Voriconazole is preferred. Liposomal amphotericin B or isavuconazole are options for severe cases or if initial treatment fails. Surgery may remove isolated lesions in immunocompromised patients. Supportive care manages complications and immunosuppression. For allergic bronchopulmonary aspergillosis (ABPA), oral corticosteroids like prednisone reduce inflammation and control symptoms. Antifungals like itraconazole suppress fungal growth. Bronchodilators alleviate bronchoconstriction and improve airflow in asthma-like symptoms. Long-term monitoring adjusts treatment. For aspergillomas, asymptomatic patients require observation and regular monitoring. Antifungal therapy prevents progression or complications in select cases. Surgical resection or transcatheter arterial embolization manage severe symptoms or life-threatening hemoptysis when conservative measures fail.
For those with intense symptoms or no response to simpler care for aspergilloma, surgery might be necessary. Removing part of the lung or entire lobes are possibilities. Blocking aspergilloma’s blood supply via bronchial artery embolization can stop life-threatening bleeding. Bronchoscopy enables doctors to see airways, take samples and diagnoseinvasive aspergillosis. Giving extra oxygen can ease breathing troubles. Chest percussion and postural drainage clear mucus from the lungs. Lung rehab teaches people with chronic respiratory problems to breathe better and live fuller lives. Proper nutrients boost the immune system and overall health, so nutritional counseling and support is key.
Role of Antifungal agents for treating Aspergillosis
Voriconazole: Voriconazole is the go-to treatment for invasive aspergillosis. It works by stopping ergosterol production, which is crucial for fungal cell walls.
Amphotericin B (including Liposomal Amphotericin B): When voriconazole isn’t suitable, amphotericin B is used as a broad antifungal. It kills fungi by damaging their cell membranes.
Isavuconazole: Isavuconazole acts similarly to voriconazole, interfering with ergosterol synthesis.
Posaconazole: If other antifungals fail or can’t be tolerated, posaconazole targets ergosterol production for invasive aspergillosis.
Itraconazole: For chronic forms like pulmonary aspergillosis, itraconazole disrupts fungal cytochrome P450, hindering ergosterol synthesis.
Caspofungin (and other Echinocandins): In certain invasive aspergillosis cases where other antifungals aren’t tolerated well, caspofungin and other echinocandins may be prescribed. These drugs block beta-glucan synthesis, which is a vital component of fungal cell walls.
Role of Corticosteroids in the treatment of Aspergillosis
Prednisone: Corticosteroids are important medicines for Allergic Bronchopulmonary Aspergillosis (ABPA). ABPA is an allergic response to Aspergillus fungi. Corticosteroids reduce inflammation and help with symptoms. Prednisone is a common corticosteroid for ABPA treatment. It’s taken by mouth. The dose is usually high at first.
Bronchoscopy helps diagnose invasive pulmonary aspergillosis. A bronchoscope collects lung samples through mouth or nose. Surgery is required for lung lesions, abscesses. Infected tissue removal controls infection. Chest tubes drain pleural effusion, empyema from pleural space. Embolization blocks bleeding vessels in life-threatening hemoptysis. Lobectomy, wedge resection treat symptomatic aspergilloma preventing bleeding, complications. Endoscopic sinus surgery removes fungal debris, polyps aiding sinus drainage, antifungal delivery in invasive fungal sinusitis.

Diagnosis comes first when dealing with Aspergillosis. Many tests can pinpoint the specific type. These assess how severe the disease is and its overall impact. Antifungal meds like voriconazole, isavuconazole, or amphotericin B treat it. The choice depends on medical past, drug interactions, and Aspergillus strain. Close watch and adjustments follow. Did treatment work? New plans may be needed. Supportive care manages symptoms and complications. This includes oxygen and proper nutrition. Surgery might be required for abscesses or diseased tissue removal, mainly in invasive cases. Drugs modulating the immune system help those with weak defenses. Prevention involves precautions and possible antifungal prophylaxis in high-risk settings. Long-term, maintenance antifungals and follow-ups prevent relapse and side effect management.
Initial dose: take a dose of 372 mg orally or intravenously every 8 hours up to 6 doses for two days
Maintenance dose: take a dose of 372 mg orally or intravenously daily
3-4 mg/kg intravenously each day Initially keep 1mg/kg/hr as the infusion rate, and reduce the infusion rate if tolerated Test dose Administer a small amount immediately before the first dose, keeping it at 1.6-8.3 mg for 15-30 minutes Observe the patient for 30 minutes
When amphotericin B therapy is intolerable or ineffective for treating pulmonary and extrapulmonary aspergillosis in immunocompromised and non immunocompromised individuals, this medication is indicated
Sporanox
200-400 mg orally daily; used with corticosteroids as combination
3-4 mg/kg intravenously each day Initially keep 1mg/kg/hr as the infusion rate, and reduce the infusion rate if tolerated Test dose Administer a small amount immediately before the first dose, keeping it at 1.6-8.3 mg for 15-30 minutes Observe the patient for 30 minutes
