Peritoneal Dialysis (or PD) is a sort of dialysis for sufferers with kidney failure the place the affected person’s stomach cavity- referred to as the peritoneum, itself serves as a synthetic kidney.

The next article describes the infectious problems that may be seen in sufferers on peritoneal dialysis.

Infectious Issues

The dialysis catheter that’s inserted into the stomach of a affected person who opts for peritoneal dialysis, referred to as the PD catheter, is usually the Achilles’ heel of the PD affected person. Infections of various hues might happen relying on the positioning. These could possibly be on the PD catheter exit website (the purpose the place catheter emerges from the pores and skin, referred to as an exit website an infection), alongside its “tunnel” (the course it takes beneath the pores and skin and within the stomach muscle, referred to as a tunnel an infection), and eventually within the stomach cavity, which is named the “peritoneum” (with the an infection there’s known as peritonitis). Here’s a image that can assist you perceive this. 

How Frequent Are Infections in Peritoneal Dialysis Sufferers?

Sure teams of sufferers are at larger danger for infectious problems like peritonitis. These embrace:

Basically, the way you do PD (manually or utilizing a cycler) shouldn’t make a distinction to the danger of creating peritonitis. As per knowledge from the UK Renal Affiliation, the common affected person can count on a danger of about one episode of peritonitis each 18 months (0.67 episodes per patient-year). That is only a rule of thumb and the danger and prevalence of an infection range broadly.

Indicators and Signs

The onset of an infection is usually famous by the affected person first. What the affected person feels, or what the nephrologist finds might range by the positioning of the an infection:

  • A superficial an infection like an exit website an infection may present redness or discharge across the level the place the catheter emerges from the pores and skin. This website is likely to be painful and fever and tenderness could possibly be current.
  • If the tunnel is concerned, ache alongside the catheter’s course together with all of the above indicators are potential 
  • If the an infection extends into the stomach cavity (peritoneum) or is the one website of the an infection, (referred to as peritonitis), diffuse stomach ache with a cloudy effluent are widespread options. Normally, the affected person will discover a drop of their ultrafiltration volumes. Fever may once more be a presenting characteristic.


If the above options are current and lift questions on potential peritonitis, discuss to your nephrologist instantly. On the very minimal, a bodily examination will affirm the presence of an infection on the catheter website or alongside the catheter tunnel. On this case, cultures could be taken from across the catheter website as a way to affirm the an infection and determine the wrongdoer bug that brought on the an infection (that is generally a micro organism, however different organisms like fungus are potential as effectively).

If the an infection is contained in the peritoneum although, then a pattern of the effluent is important which is able to then be despatched for sure exams (referred to as cell rely, Gram stain, and cultures). The outcomes of the exams will often present bacterial or fungal progress which is able to assist information the therapy of the peritonitis.


PD-related peritonitis is handled by antibiotics. The antibiotics could be given immediately contained in the peritoneum blended with the common dialysis luggage (the popular route usually), or much less generally intravenously. Therapy is likely to be mandatory for weeks at an finish. Well timed and correct therapy is important as a way to forestall the peritoneum from getting completely broken by the an infection (which in any other case may spell the tip of peritoneal dialysis for the affected person and may necessitate a change to hemodialysis). 

Superficial infections is likely to be treatable simply by oral antibiotics. The choice concerning that is greatest left to your nephrologist.
