THE PANDEMIC'S FUNGAL REVENGE: COVID-19 ASSOCIATED PULMONARY ASPERGILLOSIS (CAPA)

ABSTRACT

SESSION TITLE Pathologies of the Post-COVID-19 World SESSION TYPE Rapid Fire Case Reports PRESENTED ON 10/18/2022 1015 am - 1110 am INTRODUCTION: Since the start of the COVID-19 pandemic, COVID-19 Associated Pulmonary Aspergillosis (CAPA) has been on the rise. This superinfection, if not properly identified and treated, has shown to increase mortality up to 67% in COVID-19 patients. We are presenting a late presentation of CAPA after 4-month of COVID-19 infection and treated successfully. CASE PRESENTATION A 57-year-old female patient with past medical history type 2 diabetes mellitus, hypertension and cardiomyopathy in addition to COVID-19 pneumonia treated for months ago with azithromycin, Bamlanivimab/Etesevimab, and Dexamethasone who presents to the hospital with massive hemoptysis and shortness of breath requiring intubation and mechanical ventilation. There was no reported history of recent travel, smoking, alcohol, or illicit drug use. Physical exam showed diminished lung sounds at the right lower lobe. Her labs showed mild leukocytosis, lactic acidosis and negative COVID-19 PCR. CT scan showed dense consolidation on right lower lobe consistent with lobar pneumonia and centrilobular ground glass opacities in the right upper lobe. Bronchoscopy showed complete obstruction of right bronchus intermedius and minimal blood clots in LLL. BAL respiratory culture, fungal smear, acid fast bacilli were non-diagnostic and negative for malignancy. Patient continued to have hemoptysis and bronchoscopy was repeated with negative cytology and cultures. The patient continued to have hemoptysis and she was transferred to tertiary center were bronchoscopy was repeated and confirmed right bronchus intermedius stenosis, blood clots, and suspicious right mainstem nodules with mucosal lesion. Biopsy results from bronchoscopy came back positive for the morphologic features of Aspergillus species. The patient was started on voriconazole with significant improvement in her symptoms. DISCUSSION: The recent literature of COVID-19 suggest association between COVID infection and invasive pulmonary Aspergillosis. COVID-19 virus causes damage in the airway epithelium and enable aspergillus to invade the pulmonary tract leading to serious infections with Aspergillus. It has also been known that Aspergillus infections are associated with diabetes mellitus and immune suppression which can be precipitated by steroid use and other treatments for COVID-19 infection like IL-6 inhibitors. Here in our patient with help of tissue biopsy we diagnosed CAPA, started treatment early and treated successfully. CONCLUSIONS: CAPA can be difficult to diagnose and needs high index of suspicion in the appropriate clinical scenario when dealing with post COVID respiratory complaints like hemoptysis. Bronchoalveolar lavage alone without tissue biopsy might miss the diagnosis in the context of invasive aspergillosis like the scenario we observed in our case. Doing tissue biopsy through bronchoscopy might add more clinical benefit when Aspergillus infections are suspected.
