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.

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Peritoneal Dialysis I: Introduction and Procedure

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
