Insights

Peritonitis, a common complication in peritoneal dialysis, can arise from contaminated fluids. This study identified fungal contamination by Chaetomium globosum and Chrysonilia sitophila in dialysis fluid samples from Brazil.

Area of Science:

  • Microbiology
  • Nephrology
  • Infectious Diseases

Background:

  • Peritonitis is a frequent complication in peritoneal dialysis (PD).
  • Contamination of dialysis tubing or catheter exit sites are common causes.
  • Gram-positive bacteria cause 60% of continuous ambulatory peritonitis dialysis cases, while fungi account for 1-15%.

Purpose of the Study:

  • To report the microbiological analysis of peritoneal dialysis fluid.
  • To identify specific fungal contaminants in PD fluid in São Paulo, Brazil.

Main Methods:

  • Random selection of 49 out of 490 bottles of peritoneal dialysis fluid.
  • Microbiological analysis of selected fluid samples.

Main Results:

  • The study identified contamination of peritoneal dialysis fluid by two fungal species: Chaetomium globosum and Chrysonilia sitophila.
  • These fungi were found in the selected samples from São Paulo, Brazil.

Conclusions:

  • Chaetomium globosum and Chrysonilia sitophila are identified as contaminants in peritoneal dialysis fluid.
  • This finding highlights the importance of rigorous microbiological monitoring in PD fluid preparation and handling to prevent peritonitis.

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...

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 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...

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...

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
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...
