The Effect of Catheter Revision on Intractable Exit Site Infection in CAPD Patients / 대한신장학회잡지

BACKGROUND: Continuous ambulatory peritoneal dialysis (CAPD) is an important method of renal replacement therapy in chronic renal failure, and reduction of dialysis-associated complication is essential to successful peritoneal dialysis. But catheter related infection is a major cause of catheter loss and transferring to hemodialysis. We use an unique catheter revision method for the treatment of intractable exit-site/tunnel infection in CAPD patients. METHODS: We reviewed 322 CAPD patients on the ESI/TI from May 1995 to January 2003 at Yeungnam University Hospital. Forty-four patients had exit-site infection more than one times. Prevalence of exit-site infection, kinds of causative micro- organism and results of catheter revision were analyzed retrospectively. RESULTS: Total follow-up was 5, 834 patient months. ESI occurred on 141 occasions in 44 patients out of 322 patients and cumulative incidence of ESI was 1 per 41.4 patient months. We started empiric antibiotic therapy with oral penicillinase- resistant penicillin and quinolones, thereafter adjusted antibiotics according to the results of culture and sensitivity. The most common organism responsible for ESI was Staphylococcus aureus (MSSA, 34.8%), followed by Pseudomonas aeruginosa (25.5%). Nineteen patients had to be treated with catheter revision to control intractable ESI/TI. With analysis of ten patients who showed relapsed ESI after catheter revision, 5 patients improved with antibiotic therapy and 3 patients improved with additional secondary revision, but remaining 2 patients showed removal of peritoneal catheter to treat combined peritonitis. CONCLUSION: Catheter revision technique can be regarded as an effective alternative method to treat intractable exit site/tunnel infection before removal of catheter in CAPD patients.

The Effects of Catheter Revision and Mupirocin on Exit Site Infection/Peritonitis in CAPD Patients / 영남의대학술지

BACKGROUND: Exit site/tunnel infection causes cosiderable morbidity and technique failure in CAPD patients. We presently use a unique revision method for the treatment of refractory ESI/TI in CAPD patients and mupirocin prophylaxis for high risk patients. MATERIALS AND METHODS: We reviewed 139 CAPD patients about the ESI/TI from October 1993 to February 1999 at Yeungnam University Hospital. At the beginning of the ESI, we usually started medications with rifampicin and ciprofloxacin and then changed the antibiotics according to the sensitivity test. If the ESI had persisted and there were T1 symptoms(purulent discharge, abscess lesion around exit site), we performed catheter revision(external cuff shaving, disinfection around tunnel and new exit site on opposit direction) with a combination of proper antibiotics. We applied local mupirocin ointment at the exit site three times per week to the 34 patients who had the risk of ESI starting from October 1998. RESULTS: The total follow-up was 2401 patient months(pt. mon). ESI occurred on 105 occasions in 36 out of 139 patients, and peritonitis occurred on 112 occasions in 67 out of 139 patients. The total number of incidences of ESI and peritonitis was 1 per 23.0 pt.mon and 0 per 21.6 pt.mon. The most common organism responsible for ESI was Staphylococcus aureus(26 of 54 isolated cases, 48%), followed by the Methicillin resistant S. auresu(MRSA) (13 cases, 24%). Seven patients(5: MRSA, 2: Pseudomonas) had to be treated with a revision to control infection. Three patients experienced ESI relapse after revision. One of them improved with antibiotics, while another needed a second revision and the remaining required catheter removal due to persistent MRSA infection with re-insertion at the same time. But, there was no more ESI in these 3 patients who were received management to relapse (The mean duration: 14.0 months). The rates of ESI were significantly reduced after using mupirocin than before(1 per 12.7 vs 34.0 pt.mon, p<0.01). CONCLUSION: In summary, revision technique can be regarded as an effective method for refractory ESI/T1 before catheter removal. Also local mupirocin ointment can play a significant role in the prevention of ESI.

Intraperitoneal Vancomycin Induced Chemical Peritonitis in CAPD Patients / 대한신장학회잡지

BACKGROUND: Intraperitoneal(IP) vancomycin has been widely used for the treatment of peritonitis or exit-site infection associated with continuous ambulatory peritoneal dialysis(CAPD). However, some previous reports in the literature have suggested that IP administration of certain vancomycin may be associated with chemical peritonitis in CAPD patients. METHODS: Between 1 February 1994 and 1 February 1997, 35 consecutive CAPD patients requiring treatment with intraperitoneal vancomycin for either exit-site infection or peritonitis in the Yeungnam University Hospital were recruited retrospectively into the study. We compared retrospectively the incidence of chemical peritonitis after using two different preparations of vancomycin from different pharmaceutical companies, namely vancocin CP(R) and vancomycin(R). RESULTS: Thirty-three cases(all 26 cases given vancocin CP(R) and 7 out of the 9 cases given vancomycin(R)) showed improvement. None of them developed fever, abdominal pain or cloudy dialysate. Out of the 9 cases given IP vancomycin(R), two who currently did not have abdominal pain and cloudy dialysis effluent develolped these symptom and sign at 5 and 6 hours after administration of IP vancomycin. The chemical peritonitis may be secondary to prolonged contact of the peritoneal membrane with one or more of the impurities present in vancomycin preparation. CONCLUSION: In summary, it is necessary for the nephrologists to be aware of the possible chemical peritonitis which can be caused by the impurities of certain brand of vancomycin.
