Histological Quantification to Determine Lung Fungal Burden in Experimental Aspergillosis
Published on: March 9, 2018
[A retrospective study of 115 cases of fungal pneumonia]
Abstract:
115 cases of immunocompromised patients complicated with fungal pneumonia treated during the period from April 1968 to December 1986 were retrospectively studied. 96 were male and 19 female. Their age ranged from 6 to 84. The incidence increased significantly in recent years especially after 1983. Severe liver disease was the underlying disease in 102 (88.7%) patients. 108 (93.9%) had received antibiotics and 55 (47.9%) corticosteroids. Fungi species isolated were candida in 107 (54.9%), aspergillus in 82 (36.9%), penicillium in 7 (3.6%), mucormycetes in 6 (3%) and reotrichum in 3 (1.5%). Fever, cough, expectoration, moist rales diminished breath sounds and increase of W. B. C. and neutrophils were the important clinical features. The roentgenologic findings vary with the nature and extent of the pathologic process. Disseminated mycoses were found in 9 of the 18 autopsied cases. The characteristic pathologic findings were inflammation, abscess formation, vasculitis, infarction and hemorrhage. Extrapulmonary features such as enteritis, purulent nephritis, abnormal EKG, encephalopathy and rash were present. 93 cases received antifungal therapy including garlicin, clotrimazole, amphotericin B, nystatine, miconazole, 5-fluctosine and ketoconazole. Because these drug combinations were so complex, it is difficult to evaluate their efficiency. However the survival rate was somewhat elevated in recent years. The mortality rate of this series was 80.9%.
Insights
This retrospective study of 115 immunocompromised patients found that fungal pneumonia, often linked to severe liver disease, had a high mortality rate despite antifungal therapies. Incidence increased, with Candida and Aspergillus being common fungal culprits.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Pulmonology
Context:
- Retrospective analysis of 115 immunocompromised patients treated between 1968 and 1986.
- Significant increase in fungal pneumonia incidence observed, particularly after 1983.
- Severe liver disease was the predominant underlying condition in 88.7% of cases, with frequent prior antibiotic and corticosteroid use.
Purpose:
- To retrospectively analyze cases of fungal pneumonia in immunocompromised patients.
- To identify common fungal species, clinical features, and pathological findings.
- To assess treatment outcomes and mortality rates associated with fungal pneumonia in this population.
Summary:
- Fungal pneumonia affected 115 immunocompromised patients, predominantly males with severe liver disease. Common fungi included Candida (54.9%) and Aspergillus (36.9%). Key clinical signs were fever, cough, and elevated white blood cell counts.
- Pathological findings included inflammation, abscesses, vasculitis, infarction, and hemorrhage. Disseminated mycoses were noted in autopsied cases, with extrapulmonary manifestations also observed.
- Despite various antifungal treatments, the overall mortality rate was high at 80.9%, though survival rates showed a slight improvement in recent years.
Impact:
- Highlights the significant burden and high mortality of fungal pneumonia in immunocompromised patients, particularly those with severe liver disease.
- Provides insights into the epidemiological trends, causative agents, and clinical presentation of fungal pneumonia.
- Underscores the challenges in treating invasive fungal infections and the need for improved therapeutic strategies and early diagnosis.
