Abstract:
Invasive pulmonary aspergillosis (IPA) is an important and fatal complication in the patients with neutropenic or immunosuppressed condition. In spite of intensive treatment with anti-fungal drugs, the prognosis of the patients who have been suffered from IPA is extremely poor. This case was an 85-year-old Japanese man who was diagnosed as idiopathic thrombocytopenic purpura (ITP). He underwent high-dose corticosteroids and gamma-globulin therapy. During the hospitalization, he complained respiratory symptoms, and the abnormal shadow suggesting pulmonary infiltration and cavitation was pointed out on chest imaging. He was diagnosed as IPA because of high level of serum beta-D-glucan and positive for aspergillus antigen. Although he underwent intensive care with anti-fungal drug administration and artificial respiration, he died of respiratory distress on the 68th hospitalization. Postmortem examination disclosed severe bronchopneumonia, cavitation and pulmonary arterial thrombi in both lungs. Histological examination showed widely distributed epitheloid cell granulomata with central necrosis containing aspergillus hyphae, and vasodestructive growth of fungus with occasional organized thrombi.
Insights
This case study highlights a fatal outcome of invasive pulmonary aspergillosis (IPA) in an elderly patient with idiopathic thrombocytopenic purpura (ITP). Despite aggressive treatment, the patient succumbed to respiratory distress, underscoring IPA
Area of Science:
- Medical Mycology
- Infectious Diseases
- Pulmonology
Background:
- Invasive pulmonary aspergillosis (IPA) is a severe complication in immunocompromised patients.
- High-dose corticosteroids and gamma-globulin therapy are used for conditions like idiopathic thrombocytopenic purpura (ITP).
- Prognosis for IPA remains poor despite current antifungal treatments.
Observation:
- An 85-year-old Japanese male with ITP developed respiratory symptoms during treatment.
- Chest imaging revealed pulmonary infiltration and cavitation.
- Elevated serum beta-D-glucan and positive Aspergillus antigen confirmed IPA.
Findings:
- The patient received intensive care, including antifungal drugs and artificial respiration.
- Despite interventions, he died of respiratory distress on the 68th hospitalization day.
- Postmortem examination revealed severe bronchopneumonia, lung cavitation, and pulmonary arterial thrombi, with histological evidence of Aspergillus hyphae and vasodestructive fungal growth.
Implications:
- This case underscores the critical mortality associated with IPA, even in non-neutropenic patients.
- It highlights the diagnostic challenges and poor prognosis of IPA in elderly patients with underlying conditions.
- The findings emphasize the need for heightened clinical suspicion and timely diagnosis of IPA in immunocompromised individuals.
