Peritoneal Dialysis
A form of renal replacement therapy forpatients with end stage kidney disease
Endeavours to replace some of the functions
of the kidney such as Removing waste products
Removing excess fluid
Correcting acid/base imbalances
Correcting electrolyte imbalances
High maintenance form of therapy requiringmeticulous compliance and effort on part ofpatient

Peritoneal Dialysis
Involves the passage of solutes and water
across a membrane that separates two fluid
containing compartments-blood and dialysate
During dialysis 3 transport processes occursimultaneously
Diffusion
Ultrafiltration
Absorption

Peritoneal Dialysis
2 types
CAPDcontinuous ambulatory peritoneal
dialysis Involves on average 4 dwells per day of 4-8
hours of 22.5L each
APDautomated peritoneal dialysis
Involves 3-10 exchanges overnight of varyingamounts
Usually but not always a daytime dwell

Peritoneal Dialysis
Visceral peritoneum blood supply is from the
superior mesenteric with venous drainage
from the portal system
Parietal peritoneum blood supply is from thelumbar, intercostal and epigastric arteries
while the venous drainage is via the IVC
Main lymphatic drainage is via stomata in the
diaphragmatic peritoneum which drain into
the right lymphatic duct

Three pore model
Peritoneal capillary is the critical barrier toperitoneal transport
Movement of solute and water movement
across the capillary is mediated by pores ofthree different sizes
Large pores 20-40 nmprotein transport
Small pores 4-6nmsmall solutes eg urea,
creatinine, sodium, potassium, water Ultrapores (aquaporins)

Peritoneal Transport - Diffusion
Diffusionuraemic solutes and potassiumdiffuse from peritoneal capillary blood into thedialysate. Glucose, lactate, bicarbonate andcalcium diffuse in the opposite direction.
Diffusion depends on concentration gradient(maximal at the start), effective peritonealsurface area, intrinsic peritoneal membraneresistance, molecular weight of the solute (egsmall molecules like urea, diffuse morerapidly than larger molecules such ascreatinine)

Peritoneal Transport - Ultrafiltration
Occurs as a consequence of the osmotic gradient between thehypertonic dialysate and the relatively hypotonic peritonealcapillary blood
Driven by high concentration of glucose in dialysate
Depends on;
concentration gradient of the osmotic agent (glucose) peritoneal surface area
hydraulic conductance of the peritoneal membrane
reflection coefficient for the osmotic agent (how effectivelythe osmotic agent diffuses out of the dialysate into theperitoneal capillaries (0-1 is normalthe lower the value the
faster the osmotic gradient is lost. Gluc is 0.3 as opposed toicodextrin which is close to 1)).
Hydrostatic pressure gradientcap press around 20mmversus intraperitoneal pressure around 7mm Hg whichfavours ultrafiltration

Ultrafiltration

-
8/12/2019 Peritonitis in Pd Patients
23/64
Peritoneal TransportUltrafiltration 2
Depends on; Oncotic pressure gradient which acts to keep fluid in
blood, opposing ultrafiltration (low inhypoalbuminaemic patients so ultrafiltration tends tobe high)
Sievingoccurs when solute moves along with wateracross a semipermeable membrane by convection butsome of the solute is held backsieved. The soluteconcentration in the ultrafiltrate that has passed
through the membrane is lower than the sourcesolution. Different solutes sieve differently rangingfrom 0 (complete sieving) to 1 (no sieving)
Other osmotic agents such as icodextrin with a largereflection coefficient so ultrafiltration is sustained

Peritonitis
Peritoneal Dialysis is a great form of renal
replacement therapy
Peritonitis is a significant complication
Incidence peritonitis episodes varies from 1/9patient-months to 1/53 patient-months
(Grunberg 2005; Kawaguchi 1999)
Our figures pending but are likely to be on
the lower end of the scale

Significant morbidity
Some mortality - It is estimated that PD-
associated peritonitis results in death in 6%
of affected patients (Troidle 2006).

Peritonitis in PD pts
Catheter removal may become necessary ifpt is not responding to antibiotics or ifinfection is fungal. May be temporary orpermanent
Ultrafiltration failure can occur both acutelydue to increases in capillary permeability(Ates 2000; Smit 2004) and in the longerterm resulting in technique failure (Coles2000; Davies 1996).

Diagnosissymptoms and signs
Abdo pain most common but in a PD pt
suspect peritonitis if general malaise,
nausea, vomiting or diarrhoea
Dont be blinded by the PD These pts get other pathology
EG. Strangulated hernia, withdrawal from
steroids (if they stop taking meds suddenly
and they happen to be on steroids), rupturedviscus, ulcers, perforations etc
EXAMINE THE PATIENT

Peritoneal fluid culture
Send the whole bag
Label it (preferable with textalabel can sweat off)
Let the lab know it is coming
Ask for urgent gram stain and cell count and ask this
to be telephoned to you. Be aware that the gramstain may be negative in 50% of cases of subsequentculture proven peritonitis
Also ask for M/C/S and fungal cultures
Follow up the culture Do a full septic workup each timeincluding blood
cultures

Peritonitis
Common things occur commonly and
peritonitis is unfortunately common in our
population of PD patients
BUT Dont lose sight of the bigger picture and
these patients can suffer from any other
pathologyalways keep an open mind

Peritonitis Management
Broad spectrum coverage
Vancomycin (2.5g if more than 60kg / 2 g if 60kg orless)
Gentamicin (200mg if more than 60kg / 140mg if 60kg
or less) IP is better than IV (confirmed on large Cochrane
review April 2009)
Await culture. If gram positive, then repeat the vancdose in 1 week. If gram negative then usually
ceftriaxone 1g intraperitoneally daily for 14 days Things to note; if pseudomonas tube is very often lost.
May need to consider adding a second antibiotic suchas daily ciprofloxacin
PERITONITIS MANAGEMENT

Initial symptoms may include;
diarrhoea, vomiting, nausea,
abdominal pain, mental confusion or feeling unwell
COLLECT DRAINED BAG
*Seeadditional resources (pink section) for drainage instructions* Send entirebag for urgent MC&S (including WCC differential) and Fungal elements. ****
Must cc KRSS ****
Intraperitoneal (IP) Antibiotics (see Procedures)Give BOTH
Gentamycin 160mgs if 60kgs or less
(gramve organisms) 200mg if > 60kgs
AND
Vancomycin - 2gms if 60kgs or less
(gram +ve organisms) 2.5grams if > 60kgs
Give both in a 2L 2.3%bag
Dwell in the abdomen for minimum 6 hours(Consult microbiologist if Vanc or Gent allergy)
must be able to read newspaper print through the
bag
LOOK FOR OTHER CAUSES
Call PD Coordinator or
Renal GP
ATTENTION:Vanc and Gent provide some coverage while
awaiting sensitivities.****Further antibiotics WILL be required ****
If Staph/gram +ve, give IP Vancomicin again on Day 7
If gram negative, refer to sensitivities, but
usually 14 days of IP Ceftriaxone1gmYOU MUSTfollow up the MC & S 48 hours after initial IP treatment.
A WCC > 100 confirms peritonitis.If the patient is not improving within 24 hrs, or any other concerns, contact PD coordinator

Peritonitisfungal infection
If fungal organisms are seen on gram stain,
or cultured, it is unlikely you will be able to
save the tube
Once the tube is colonized, the only cure isremoval of tube, peritoneal rest (pt on
Haemodialysis for a few months) and then
start from scratch

Peritonitis
If you think that the patient has peritonitis but youthink they have life threatening sepsis eghypotension, tachycardia, fever (or no fever as maynot be able to mount an immune response), alteredconscious state etc, your patient is likely to require IV
broad spectrum antibiotics. Ring the microbiologiston call. Dont wait to get IP regime in. That can go inwhile you are making calls and obtaining results.
Antibiotics must be given within 1 hour ofpresentationit is an emergency.
I usually ring SCGH as they maintain a 24 hourconsultant micro roster 93463333 but remember allour patients who require transfer must go to RoyalPerth Hospital as they are under the RPH consultant

Peritonitis
Patients can have dual pathology
Eg it is not uncommon for patients to have
peritonitis, delay treatment, splint their
abdomen and get pneumonia. This needs tobe treated as per the normal guidelines for
pneumonia

Additives to bags
Vancomycin, aminoglycosides andcephalosporins are safe to mix in the samebag
Aminoglycosides are incompatible withpenicillins
Vancomycin is stable for 28 days in dialysate(normal room temp)
Cefazolin is stable for 8 days
Gentamicin is stable for 14 days
Heparin added decreases duration of stability

Peritonitis
Often get formation of fibrin clots which
increases risk of catheter block
May need to add 500units of heparin to 1 or 2
bags a day until fibrin clots decrease Constipation is commonyou may need to
stop the calcium based phosphate binders
temporarily but better off using aperients
early and preventing the need to alter routinemeds

Fluid regimes
Depends whether patient is overloaded orunderloaded
Can usually continue normal regime but tailor to
patient If BP low, use 1.5% bags x 4 a day
If BP high use 2.3% bags, minimum of 4 a day
Aim for BP 120/
APD pts can continue on APD or if needed canconvert temporarily to CAPDin Broome withresources this should not be necessary

Peritonitis
Can get changes in the permeability of the peritoneal
membrane
Permeability to water, glucose and proteins is
increased
Rapid glucose absorption from the dialysis solutionreduces amount of ultrafiltration and can result in fluid
overload
May need high glucose concentration dialysate with
shorter dwells Hyperglycaemia is common
Protein loss is increased in peritonitis so patients will
need high protein supplements

Peritonitis
Fungal peritonitis
We tend to try and save the tube by giving
antifungals but guidelines recommend prompt
removal of catheter, conversion tohaemodialysis for a few weeks and then start
from scratch
Penetration of antifungals to peritoneum other
than with IP administration, is poor

Peritonitis
Refractory disease
Defined as disease that is treated with
appropriate antibiotics for 5 days without
improvement Catheter removal necessary to reduce
morbidity and preserve peritoneum
Increased with gram neg bugs

Peritonitis
Relapsing disease
Peritonitis with the same organism within 4 weeks of stoppingtherapy
Usually Staph epidermidis or a gram negative organism
If pseudomonas or gram negatives, remove the catheter
If staph, may be able to rescue with repeat vancomycin weeklyfor a month or may be able to remove the tube andsimultaneously insert a new tube (as opposed to any otherorganism where a 2 month peritoneal rest is required)
Sometimes can use urokinase to strip the biofilm (bacteria
entrapped in fibrin in the peritoneal membrane) in relapsingdiseaselast resort but worth a go

Peritonitis
20% of episodes temporally associated with
exit site and tunnel infections (Piraino et al
2005)
Treat exit site infections if red and purulent Swab it
Start Flucloxacillin empirically and change or
add ciprofloxacin if gram neg
Exit sites are another whole topic

Cochrane Review 2009
Implications for practiceAt the present time broad spectrum antibiotics should be initiated at thetime a diagnosis of peritonitis is made. When choosing antibiotics theside-effect profile, local drug resistance patterns and previous antibioticuse and infection history in the individual concerned should beconsidered. In cases of recurrent peritonitis dialysis catheters shouldbe removed rather than using intraperitoneal urokinase.
Currently available evidence from RCTs is inadequate in many areas
of clinical practice important in the management of PD-associatedperitonitis. This is a limiting factor in the provision of definitivetreatment guidelines.

Cochrane Review 2009
Implications for researchFurther studies are required to establish the most effective treatment for peritoneal dialysis-associated peritonitis. An essential feature of such studies is inclusion of enough patients toensure adequate power to assess meaningful long and short term outcomes. Short termoutcomes should extend beyond whether cure is achieved without catheter removal, forexample duration of systemic inflammation. Study of long-term outcomes should includepermanent transfer to haemodialysis, development of ultrafiltration failure patient death andlate recurrent episodes of peritonitis beyond four weeks from the original episode.
Specific interventions that would be of value include early versus late catheter removal.Studies designed to study infections due to specific organisms would also be valuable. Anexample is a study of glycopeptide versus cephalosporin therapy in peritonitis due tocoagulase negative Staphylococcal species. The majority of studies have included patientson CAPD rather than APD hence studies designed to test the efficacy of antibiotics in APDare required. This is particularly applicable to studies of intermittent versus continuousdosing when cycler dwell times may well influence pharmacokinetics.Future research should be conducted using standard definitions, with inclusion ofinformation about factors that may influence the response to therapy such as prophylaxis
regimens and dialysis solutions used. Current ISPD guidelines provide a comprehensive listof requirements for future studies that should be referred to when designing studies.
