What is Pathology – Histoplasmosis
Histoplasma capsulatum is a dimorphic fungus that causes systemic fungal illness.
• In soil enriched by bird droppings, an organism flourishes.
After forming, fungus spores are ingested.
• In the lungs, fungal spores transform into yeast once they reach body temperature. The local lymphatic system then absorbs the yeast, allowing it to enter the circulation. 2-3 weeks after infection, cellular protection sets in.
Evaluation and Diagnostic Results
Fever, cough, anemia, liver and spleen enlargement, leukopenia, pneumonia, adrenal necrosis, and gastrointestinal system ulcers are all symptoms of a widespread illness.
• A positive histoplasmin skin test or urine antigen test as well as increasing complement fixation and agglutination titers are signs of chronic pulmonary histoplasmosis, which causes lung cavitations resembling those seen in TB. confirmed through stained tissue dissection or H. capsulatum culture from bone marrow, blood, lymph nodes, or sputum.
Pleural effusion and heart tamponade are complications.
• A decline in mental condition.
medical attention and surgical procedure
• Itraconazole, ketoconazole, and intravenous amphotericin B.
Fluconazole will be prescribed to immunocompromised patients for life.
• Immunosuppressed patients who are HIV-positive, receiving chemotherapy, or receiving radiation treatment should avoid coming into contact with any dirt that may have been contaminated by bird droppings.
• Encourage the client to promptly disclose any cough or fever.
• Track vital signs, liver function tests (LFTs), vital breath sounds, and gastrointestinal discomfort suggestive of ulceration every 4 hours.
Monitor the complete blood count (CBC) for anemia, the blood chemistry for catecholamines, and the chest x-ray for cavitations similar to those seen in TB.
