Background Context:
Fungal spondylodiscitis is often because of Candida albicans or other common Candida species, whereas unusual strains such as Candida sake are often thought to be nonpathogenic.
Purpose:
To report the first case of spondylodiscitis caused by C sake and its outcome after antimycotic therapy; as the disease occurred in a patient undergoing hemodialysis (HD), we also discuss the potential conditions related to the uremic state and to HD itself, which may predispose to spondylodiscitis.
Study Design/Setting:
Case report.
Methods:
Report of the patient's clinical findings and review of the literature concerning spondylodiscitis in HD patients and infections caused by C sake.
Results:
The patient was a 48-year-old woman with end-stage renal disease (ESRD) undergoing HD who presented with back pain; spine computed tomographic (CT) scans showed lumbar spondylodiscitis with large bilateral abscesses in the psoas muscles, with an imaging appearance resembling that of Pott's disease. Surprisingly, C sake was isolated from the cultures of the liquid obtained by CT-guided aspiration of both abscesses, and fluconazole therapy was strikingly effective in inducing abscess regression and healing of spondylodiscitis.
Conclusions:
In patients with chronic disorders such as ESRD, spondylodiscitis can also be caused by rare fungal strains that are usually thought to be nonpathogenic; a correct diagnostic workup is essential, as such forms can promptly respond to common antimycotic agents.
Insights
This case report details the first instance of spondylodiscitis caused by Candida sake, a rare fungal pathogen. Effective treatment with antifungal therapy highlights the importance of considering unusual fungi in immunocompromised patients.
Area of Science:
- Mycology
- Infectious Diseases
- Nephrology
Background:
- Fungal spondylodiscitis typically involves common Candida species.
- Unusual Candida strains, like Candida sake, are often considered nonpathogenic.
- Patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD) are susceptible to infections.
Observation:
- A patient with ESRD on HD presented with lumbar spondylodiscitis and psoas abscesses.
- Imaging findings mimicked Pott's disease.
- Candida sake was unexpectedly isolated from abscess aspirates.
Findings:
- Successful treatment of spondylodiscitis and abscesses was achieved with fluconazole.
- Candida sake, previously considered nonpathogenic, caused severe spinal infection.
- The patient's uremic state and HD may have predisposed to this infection.
Implications:
- Rare fungal strains can cause serious infections in immunocompromised individuals.
- Prompt diagnosis and appropriate antifungal therapy are crucial for favorable outcomes.
- Consideration of unusual pathogens is essential in patients with chronic conditions and infections.
