B37.1

Clinical Causes: Overgrowth of Candida species in the body Inhalation of Candida spores from the environment Spread from other parts of the body, such as the mouth or gut Compromised immune defenses, making the lungs more susceptible Prolonged use of antibiotics or corticosteroids Ventilator use or invasive respiratory procedures in hospitalized patients

Key Symptoms: Persistent cough, which may produce sputum Shortness of breath or difficulty breathing Chest discomfort or pain, especially while breathing Fever, often low-grade but can be high during severe infections Fatigue and general malaise Wheezing or abnormal lung sounds upon listening with a stethoscope

Diagnosis Path: Chest X-ray or CT scan to detect areas of lung involvement such as infiltrates or nodules Sputum analysis with microscopy and culture to identify Candida species Bronchoscopy with bronchoalveolar lavage to obtain lung tissue or fluid samples Serological tests for Candida antigens or antibodies Histopathological examination if a lung biopsy is performed

Treatment Protocols: Systemic antifungal agents such as fluconazole, itraconazole, or amphotericin B Addressing underlying immune deficiencies or predisposing factors Supportive care including oxygen therapy if breathing is compromised Monitoring for potential drug side effects and interactions In severe cases, hospitalization and intravenous antifungal therapy may be necessary
