Insights
This case highlights a fatal instance of Candida prosthetic valve endocarditis co-occurring with COVID-19. Early antifungal treatment is crucial for patients with prosthetic valves to improve outcomes.
Area of Science:
- Infectious Diseases
- Cardiology
- Critical Care Medicine
Background:
- Distinguishing Coronavirus disease 2019 (COVID-19) from Candida prosthetic valve endocarditis is challenging due to overlapping clinical presentations.
- Patients with prosthetic cardiac valves are at increased risk for severe outcomes when co-infected with COVID-19 and fungal pathogens.
Purpose of the Study:
- To report a case of Candida tropicalis prosthetic valve endocarditis in a patient with COVID-19.
- To emphasize the critical need for prompt diagnosis and antifungal intervention in such complex cases.
Main Methods:
- A 66-year-old male with a history of valve replacement presented with symptoms suggestive of both COVID-19 and endocarditis.
- Diagnostic tools included transesophageal echocardiography, chest CT scan, RT-PCR for COVID-19, and blood cultures.
- The patient received antifungal therapy but unfortunately succumbed to septic shock.
Main Results:
- The patient presented with fever, respiratory distress, neurological symptoms, and hypoxia.
- Echocardiography revealed large vegetations on the mechanical mitral valve.
- Blood cultures identified Candida tropicalis, and COVID-19 was confirmed via RT-PCR.
Conclusions:
- This case underscores the critical importance of early diagnosis and prompt antifungal treatment in COVID-19 patients with prosthetic cardiac valves.
- Failure to rapidly initiate antifungal therapy can lead to unfavorable outcomes, including mortality.
- Integrated management strategies are essential for co-infected patients to mitigate risks.
Background And Purpose:
Coronavirus disease 2019 (COVID-19) and Candida prostatic valve endocarditis present various clinical manifestations which may overlap; hence, discrimination between them is extremely difficult.
Case Report:
The case was a 66-year-old man with a past medical history of mitral and aortic valves replacement one year before COVID-19 co-infection. He was admitted with fever (for 7 days), shortness of breath, cough, seizure, lethargy, headache, and 85% oxygen saturation. Transesophageal echocardiography revealed multiple large-sized, highly mobile masses on both sides of the mechanical mitral valve highly suggestive of vegetation. Chest computed tomography scanning showed simulating scattered COVID-19 peripheral ground-glass opacities confirmed by reverse-transcription polymerase chain reaction. The set of blood cultures yielded yeast colonies that were identified as Candida tropicalis. The patient died of septic shock shortly after receiving antifungal therapy.
Conclusion:
This case emphasized the importance of early diagnosis and implementation of antifungal treatment, particularly in patients with prosthetic cardiac valves, to reduce their unfavorable outcomes in COVID-19 patients.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
