B40.2

Clinical Causes: Inhalation of spores from the environment, particularly in wooded, moist areas Exposure to soil containing Blastomyces dermatitidis spores Activities involving disturbance of contaminated soil, such as farming, outdoor recreation, or construction

Key Symptoms: Persistent cough Chest pain Fever and chills Night sweats Fatigue and weakness Shortness of breath Unintentional weight loss Muscle aches and joint pain

Diagnosis Path: Diagnosis of pulmonary blastomycosis typically involves several steps, including a detailed medical history and physical examination. Doctors may order diagnostic tests such as chest X-rays or CT scans to visualize lung involvement. Confirmatory tests include fungal cultures, histopathological examination of lung tissue, or detection of Blastomyces dermatitidis DNA via molecular methods. Serological tests, which detect antibodies, may assist but are less definitive.

Treatment Protocols: Treatment generally involves antifungal medications. The most common medications used are itraconazole or amphotericin B, depending on the severity of the disease. Mild cases may respond well to oral antifungals taken over several months, while more severe infections require hospitalization and intravenous therapy. Rest and supportive care are also vital components of treatment to help the body recover. Complete adherence to prescribed medication regimens is important to prevent recurrence or complications.
