Abstract:
Coronavirus Disease (COVID-19) associated fungal infections including pulmonary aspergillosis, mucormycosis and other invasive fungal infections have been increasingly described in the current pandemic. Aspergillus osteomyelitis is a rare clinical form of aspergillosis. Most cases of Aspergillus osteomyelitis are reported in immunocompromised patients. We describe four cases of vertebral osteomyelitis caused by Aspergillus species in the post COVID-19 setting. To the best of our knowledge, Aspergillus vertebral osteomyelitis has not been described in the post COVID-19 setting. None of the four patients described in this series were immunocompromised and all of them had received steroids during their hospitalization for COVID-19 pneumonitis. Vertebral osteomyelitis caused by Aspergillus species is a rare clinical manifestation of Aspergillosis. It requires a high index of suspicion and prompt efforts to establish a diagnosis. For a clinician involved in assessing a patient with Spondylodiscitis, the work up must not be limited to testing for Tuberculosis. Every attempt must be made to establish the microbiological diagnosis. Combined medical and surgical management is generally needed for Aspergillus osteomyelitis.
Insights
Four non-immunocompromised patients developed Aspergillus vertebral osteomyelitis after COVID-19, often after steroid treatment. This rare fungal infection requires prompt diagnosis and combined treatment.
Area of Science:
- Infectious Diseases
- Mycology
- Orthopedics
Background:
- Fungal infections, including invasive aspergillosis, are increasingly reported in patients with Coronavirus Disease (COVID-19).
- Aspergillus osteomyelitis, a rare form of aspergillosis, typically affects immunocompromised individuals.
- Vertebral osteomyelitis is a serious spinal infection that can be challenging to diagnose.
Observation:
- This study reports four cases of vertebral osteomyelitis caused by Aspergillus species in patients following COVID-19.
- Notably, none of the affected patients were immunocompromised.
- All patients had received corticosteroid therapy during their hospitalization for COVID-19 pneumonitis.
Findings:
- This is the first description of Aspergillus vertebral osteomyelitis in the post-COVID-19 setting.
- The findings suggest a potential link between COVID-19, steroid treatment, and the development of this rare fungal bone infection.
- Diagnosis requires a high index of suspicion and thorough microbiological investigation, extending beyond typical workups for spondylodiscitis.
Implications:
- Clinicians should consider Aspergillus vertebral osteomyelitis in patients presenting with spondylodiscitis after COVID-19, especially those treated with steroids.
- Prompt and accurate microbiological diagnosis is crucial for effective management.
- Combined medical and surgical interventions are generally necessary for successful treatment of Aspergillus osteomyelitis.
