A particular kind of mold (fungus) can infect people and produce aspergillosis infection. Aspergillus mold grows indoors and outdoors like soil, decaying vegetation, and organic matter. Most of these mold strains are safe to breathe in. Still, a small number can pose a substantial risk to those with compromised immune systems, underlying lung conditions, or asthma. The spores cause an allergic reaction in certain individuals.
Some people get lung infections, ranging from minor to major. When the infection reaches blood vessels and beyond, it results in invasive Aspergillosis, the most dangerous type of the disease. It happens when an infection quickly moves from the lungs to the skin, heart, brain, or kidneys. Only people with compromised immune systems due to immune system diseases, bone marrow transplants, or chemotherapy for cancer can develop invasive Aspergillosis. This type of Aspergillosis can be deadly if left untreated.
Symptoms
You can experience a rise in temperature and fever.
You can experience shortness of breath and chest pain.
Individuals can experience skin lesions.
People can experience hemoptysis [coughing up blood].
You can experience headaches.
Individuals can also experience joint pain.
Diagnosis
Imaging tests: Your doctor will need an X-ray or a CT scan to identify the detailed images.
Sputum test for respiratory secretions: This test involves staining a sputum sample with a dye and looking for Aspergillus filaments. To aid in confirming the diagnosis, the specimen is then put in a culture that promotes the growth of the mold.
Biopsy: A tissue biopsy may be performed by taking a sample from the sinuses or lungs. It is used as a confirmatory test for detection.
Complications
Scarring of tissue
Air passageway becomes wider
Lung areas that have collapsed
Spreads and harms more organs
Damage in tissues
Respiratory malfunction.
Sepsis
Treatment
The treatment approaches typically involve the use of antifungal medicines and oral corticosteroids that help to eradicate the invasive fungal Aspergillosis.
1. Antifungal medicines:
1. Voriconazole: Voriconazole works by inhibiting the production of cytochrome enzymes in fungi, which are essential for synthesizing a substance called ergosterol. The complete absence of ergosterol in the fungal cell wall is believed to be the mechanism behind Voriconazole's antifungal activity. Voritrol 200mg tablet contains the active compound voriconazole, that is widely prescribed.
2. Isavuconazole: It is prescribed in patients who are allergic to and have failed voriconazole therapy.
3. Amphotericin B: Certain lipid-based formulations like amphotericin B can be used when the preferred standard treatment approaches do not respond. It can be used as salvage therapy when the disease is severe.
2. Oral corticosteroids:
Oral corticosteroids can be used as adjuvant therapy. It helps to manage various complications like bronchospasms, allergic reactions, and acute respiratory distress syndrome. Your doctor will prescribe corticosteroids if the potential benefits outweigh the risks involved in the treatment. The risks that you will experience are immune suppression, making your body vulnerable to more infections and increasing the growth of underlying fungal infections.
3. Surgical management:
Surgical debridement: This involves the process of removing the damaged tissue and improving the treatment outcomes. This process is done when antifungal therapy alone is not sufficient.
Resection: Removal of the affected lung tissue may be considered surgically for patients with invasive pulmonary Aspergillosis and localized lung lesions, especially if antifungal medication is not controlling the infection.
4. Supportive management:
Mechanical ventilation
Supplemental oxygenation
Hemodynamic support
Conclusion
Invasive Aspergillosis is indeed a life-threatening condition. It must be diagnosed early and treated with utmost care. Personalized treatment approaches can be built by consulting an infectious care specialist and testing for resistance to antifungals before the therapy. Managing complications by effective supportive care therapy helps to improve patient well-being.
