Summary
Prototheca wickerhamii can cause infrapatellar bursitis. Intrabursal amphotericin B injections effectively treated a relapsed case in an immunocompetent patient, leading to a cure.
Area of Science:
- Infectious Diseases
- Dermatology
- Orthopedics
Background:
- Prototheca wickerhamii is a rare cause of opportunistic infections.
- Infrapatellar bursitis can be challenging to treat, especially when recurrent.
- Immunocompetent individuals can be affected by Prototheca infections.
Purpose of the Study:
- To report a case of infrapatellar bursitis caused by Prototheca wickerhamii.
- To evaluate the efficacy of intrabursal amphotericin B for treating relapsed Prototheca bursitis.
Main Methods:
- A 54-year-old immunocompetent male presented with infrapatellar bursitis.
- Initial treatment included bursectomy, which resulted in clinical and microbiological relapse.
- Six weekly intrabursal injections of 5 mg conventional amphotericin B were administered.
Main Results:
- The patient experienced a relapse after initial surgical treatment.
- Intrabursal amphotericin B treatment led to complete clinical resolution.
- Microbiological cure was achieved and maintained four months post-treatment.
Conclusions:
- Prototheca wickerhamii can cause persistent infrapatellar bursitis.
- Intrabursal amphotericin B is a viable and effective treatment option for relapsed Prototheca bursitis.
- This case highlights the importance of considering rare pathogens and exploring localized treatment strategies.
