Clinical Report: Invasive Pulmonary Aspergillosis Due to Aspergillus lentulus
Overview
This case report details a rare instance of invasive pulmonary aspergillosis caused by Aspergillus lentulus in a 2-year-old boy with chronic granulomatous disease (CGD) who presented with prolonged fever. The patient was successfully treated with a combination of voriconazole and micafungin after initial antifungal therapy failed.
Background
Aspergillus lentulus is a drug-resistant fungus primarily affecting immunocompromised adults, making its occurrence in children particularly rare, with limited documented cases. Chronic granulomatous disease (CGD) significantly increases susceptibility to invasive fungal infections due to impaired immune responses. This case highlights the need for accurate identification of pathogens and effective treatment strategies in pediatric patients with CGD.
Data Highlights
No numerical data available in the article.
Key Findings
['Aspergillus lentulus is a slow-growing, drug-resistant fungus.', 'This case is the first reported instance of A. lentulus infection in a child with CGD.', "Initial empirical antifungal therapy did not resolve the patient's symptoms.", 'Metagenomic next-generation sequencing (mNGS) confirmed the diagnosis of A. lentulus.', 'The patient improved clinically after receiving combination therapy with voriconazole and micafungin.', 'There is currently no consensus on the optimal antifungal regimen for pediatric A. lentulus infections.']
Clinical Implications
Clinicians should consider the possibility of A. lentulus infection in pediatric patients with CGD presenting with unexplained fever and respiratory symptoms. The use of mNGS can aid in the rapid identification of the causative organism, which is crucial for effective treatment.
Conclusion
This case underscores the importance of timely diagnosis and appropriate antifungal therapy in managing invasive pulmonary aspergillosis in pediatric patients, particularly those with underlying immunodeficiencies.
