Complications of chronic necrotizing pulmonary aspergillosis: review of published case reports

Area of Science:

• Pulmonology
• Infectious Diseases
• Mycology

Background:

• Chronic necrotizing pulmonary aspergillosis (CNPA) is a severe form of chronic pulmonary aspergillosis (CPA).
• It primarily affects individuals with underlying lung conditions, even those with competent or mildly compromised immune systems.
• CNPA is linked to significant morbidity and mortality, often necessitating prolonged antifungal interventions.

Purpose of the Study:

• To review documented complications associated with CNPA.
• To identify risk factors contributing to the development of CNPA.
• To enhance understanding of the long-term prognosis and potential sequelae of CNPA.

Main Methods:

• Systematic review of published literature reporting cases of CNPA complications.
• Analysis of identified cases to highlight associated risk factors and clinical presentations.

Main Results:

• CNPA complications include pseudomembranous necrotizing tracheobronchial aspergillosis, ankylosing spondylarthritis, pulmonary silicosis, ARDS, MAC disease, tuberculosis superinfection, and pneumothorax.
• Diagnosis of CNPA remains challenging, often requiring bronchoscopic examination of mucus plugs and necrotic material.
• Radiographic stability does not exclude CNPA in immunocompromised patients.

Conclusions:

• Prompt diagnosis and treatment of Aspergillus intraluminal growth are vital.
• Early antifungal therapy can aid in managing CNPA and preventing severe complications.
• Further research is needed to fully elucidate the long-term prognosis and management strategies for CNPA.
