Steroid Impregnated Tape in the Treatment of Over-granulating Peritoneal Dialysis Exit Sites
Steroid Impregnated Tape in the Treatment of Over-granulating Peritoneal Dialysis Exit Sites
Kidney failure is a devastating illness requiring treatment with dialysis or transplantation
 to preserve life. Individuals unable to have transplants are managed by peritoneal dialysis
 (PD)or haemodialysis (HD). PD involves the placement of a soft, flexible plastic tube
 (catheter) into the abdomen, allowing dialysis fluid to be drained in and out of the
 peritoneal cavity. This catheter exits from a hole in the abdomen and occasionally patients
 can have complications at this exit site. One possible complication is over-granulation.
 Over-granulation occurs as the wound attempts to heal and the skin around the exit site
 becomes red,'wet','bumpy' and stands 'proud' of the surrounding skin. An over-granulating
 exit site can lead to discomfort, pain, bleeding and harbour infection. More serious
 complications include dialysis failure, sepsis and death. There are several ways to treat
 over-granulation but there is limited research evidence to demonstrate which treatment is
 best. The study aims to compare current standard treatment which involves the application of
 silver nitrate by qualified nursing staff to chemically burn the tissue away, with an
 alternative treatment which involves the application of steroid impregnated tape to the area
 of over-granulating tissue by the patient themselves.
This study will be a United Kingdom wide multi-centre trial. A minimum of 40 patients in each
 arm will be recruited. Subjects will be identified using a standardised exit site assessment
 tool by PD nurses in participating units during the routine care of their PD population. Any
 subject with an over-granulating exit site deemed to meet the agreed standard for treatment
 will be invited to participate.

 Therapy will be administered for two weeks followed by an additional two weeks if clinically
 indicated. Treatment must be according to randomisation for the first 28 days. If after 14
 days the over-granulation is worse than at day 0, then a medical decision to continue
 treatment may be taken. A further two weeks of the designated treatment may then be
 administered although this can be discontinued at any point if a satisfactory clinical
 response is observed.
Inclusion Criteria:

 and the site must be clinically improving.

 -  Subject is > 18 years of age

 -  Subject is able to give informed consent

 Exclusion Criteria:

 -  Subject has had peritonitis treated in the previous month

 -  Subject has been treated with silver nitrate or topical steroids in the previous 2
 weeks

 -  Subject is receiving oral steroids

 -  Patient is unable to give informed consent

 -  Patient is participating in a clinical trial of an intervention relating to PD
 catheters.

 -  Subject is pregnant or unwilling to use an effective method of contraception during
 the course of the study
