Abstract:
Peritoneal dialysis-related peritonitis (PDRP) is a commonly encountered complication in patients undergoing peritoneal dialysis (PD). Establishing the causative organism in PDRP allows for targeted antibiotic selection, helps to guide duration of therapy, and determines the need for catheter removal. Microbacterium is a genus of aerobic gram-positive bacilli found in the environment. Its detection in clinical isolates has increased owing to improved microbiology diagnostics. We present a case of PDRP due to M. paraoxydans and review the epidemiology, clinical manifestations, and available evidence for treatment of this organism. The high rate of recurrent infection and limited data regarding antimicrobial susceptibility testing pose significant challenges in the management of PDRP caused by Microbacterium species.
Insights
Peritoneal dialysis-related peritonitis (PDRP) can be caused by Microbacterium paraoxydans. Managing PDRP from Microbacterium species presents challenges due to recurrent infections and limited susceptibility data.
Area of Science:
- Microbiology
- Nephrology
- Infectious Diseases
Background:
- Peritoneal dialysis-related peritonitis (PDRP) is a frequent complication in patients on peritoneal dialysis (PD).
- Identifying the causative pathogen is crucial for effective treatment and patient management.
- Microbacterium species, aerobic gram-positive bacilli, are increasingly detected in clinical settings due to enhanced diagnostics.
Observation:
- This report details a case of PDRP caused by Microbacterium paraoxydans.
- The study reviews the epidemiology and clinical presentation of Microbacterium-associated PDRP.
- Current evidence regarding treatment strategies for this specific pathogen is examined.
Findings:
- Microbacterium paraoxydans was identified as the causative agent of PDRP in the presented case.
- Management of PDRP due to Microbacterium species is complicated by a high incidence of recurrent infections.
- Limited data on antimicrobial susceptibility testing for Microbacterium species poses therapeutic challenges.
Implications:
- This case highlights the importance of considering less common organisms like Microbacterium in PDRP etiology.
- Further research is needed to establish optimal antimicrobial regimens and susceptibility breakpoints for Microbacterium species in PDRP.
- Improved diagnostic and therapeutic strategies are required to address the challenges in managing Microbacterium-related PDRP.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
