Abstract:
We report a case of melioidosis presenting as peritonitis in a patient on continuous ambulatory peritoneal dialysis (CAPD). A 47-year-old man, a lorry driver, with end-stage renal disease due to diabetes mellitus on CAPD presented in PD-related peritonitis. He was started on intraperitoneal cloxacillin and ceftazidime, and changed to intraperitoneal vancomycin and meropenam after day 5 due to nonresponse. Burkholderia pseudomallei was identified from the dialysate culture. He was treated with intraperitoneal meropenam for two weeks, and IV ceftazidime for 4 weeks. He responded, and the Tenckhoff catheter was not removed. He was discharged well and continued on oral sulfamethoxazole/trimethoprim for six months. This patient had done his PD exchanges in a lorry.
Insights
Melioidosis can cause peritonitis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Early identification and appropriate antibiotic treatment are crucial for successful management and catheter preservation.
Area of Science:
- Infectious Diseases
- Nephrology
- Microbiology
Background:
- Continuous ambulatory peritoneal dialysis (CAPD) is a common treatment for end-stage renal disease.
- Peritonitis is a serious complication of CAPD, requiring prompt diagnosis and treatment.
- Melioidosis, caused by Burkholderia pseudomallei, is an infectious disease endemic in certain tropical regions.
Observation:
- A 47-year-old male CAPD patient presented with symptoms of peritonitis.
- The patient, a lorry driver, performed dialysis exchanges in his vehicle.
- Initial antibiotic treatment was ineffective, necessitating a change in regimen.
Findings:
- Dialysate culture identified Burkholderia pseudomallei as the causative agent of peritonitis.
- The patient was successfully treated with a combination of intraperitoneal meropenem and intravenous ceftazidime.
- The Tenckhoff catheter was preserved, and the patient completed a six-month oral antibiotic course.
Implications:
- This case highlights the importance of considering melioidosis in CAPD peritonitis, especially in patients with relevant exposure history.
- Aggressive antibiotic therapy can lead to successful treatment outcomes without catheter removal.
- Environmental factors, such as performing dialysis in a lorry, may play a role in pathogen exposure.
