Insights

Peritonitis from Elizabethkingia miricola, a rare pathogen, can complicate peritoneal dialysis. This case highlights successful treatment with antibiotics, improving patient outcomes in dialysis care.

Area of Science:

  • Microbiology
  • Nephrology
  • Infectious Diseases

Background:

  • Peritoneal dialysis (PD)-associated peritonitis is a serious complication.
  • It can lead to increased mortality and treatment changes.
  • Rare and emerging pathogens present unique management challenges.

Observation:

  • A case of PD peritonitis caused by Elizabethkingia miricola was identified.
  • The infection was suspected to arise from direct contamination.
  • This represents the first reported instance of this pathogen causing PD peritonitis.

Findings:

  • Elizabethkingia miricola was successfully eradicated.
  • Treatment involved a combination of intraperitoneal and oral antibiotics.
  • The patient's PD therapy was continued without discontinuation.

Implications:

  • This case expands the spectrum of known PD peritonitis pathogens.
  • It demonstrates the efficacy of standard antibiotic protocols for rare organisms.
  • Highlights the importance of considering unusual pathogens in refractory peritonitis.

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...

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
