PATIENTS AND METHODS: The open, paramedian approach is the commonest technique to insert the 62-cm coiled double-cuffed Tenckhoff peritoneal catheter. All patients with catheters inserted between January 2004 and November 2007 were retrospectively analyzed for demographics and followed for up to 1 month for complications. We excluded patients whose catheters had been anchored to the bladder wall and who underwent concurrent omentectomy or readjustment without removal of a malfunctioning catheter (n = 7). Intravenous cloxacillin was the standard preoperative antibiotic prophylaxis. ♢
RESULTS: Over the 4-year study period, 384 catheters were inserted under local anesthetic into 319 patients [201 women (62.8%); mean age: 49.4 ± 16.7 years (range: 13 - 89 years); 167 (52.2%) with diabetes; 303 (95%) with end-stage renal disease] by 22 different operators. All Tenckhoff catheters were inserted by the general surgical (n = 223) or urology (n = 161) team. There were 29 cases (7.6%) of catheter migration, 22 (5.7%) of catheter obstruction without migration, 24 (6.3%) of exit-site infection, 12 (3.1%) of leak from the main incision, 14 (3.6%) of culture-proven wound infection, 11 (2.9%) post-insertion peritonitis, and 1 (0.3%) hemoperitoneum. No deaths were attributed to surgical mishap. ♢
CONCLUSIONS: The most common complication was catheter migration. The paramedian insertion technique was safe, with low complication rates.
Objectives: This study aimed to evaluate the patterns of intraperitoneal (IP) antibiotic utilization for the treatment of peritonitis in CAPD patients.
Materials and Methods: This is a retrospective study conducted at a tertiary hospital setting in Malaysia. Medical records of CAPD patients who were diagnosed with peritonitis and registered with National Kidney Registry from 2013 to 2018 were reviewed. Types of antibiotics used and its dose and duration were recorded and reported using the anatomical therapeutic chemical/defined daily dose (ATC/DDD) system.
Results: A total of 105 peritonitis episodes were recorded from 72 patients. The most common first-line empirical antibiotic combinations used were ceftazidime/cefazolin (40%, n = 42), followed by cefepime/cefazolin (30.5%, n = 32) and ceftazidime/cloxacillin (25.7%, n = 27). The definitive therapy for culture-proven CAPD-related peritonitis (CAPD-P) showed that vancomycin was the most frequently prescribed antibiotic (31.7%, n = 26/82), followed by amikacin (14.6%, n = 12/82), meropenem (11%, n = 9/82) and ampicillin (11%, n = 9/82). Ciprofloxacin was among the least prescribed definitive antibiotics for CAPD-P (2.4%, n = 2/82) but the DDD/100 patient-days estimates showed that it had the highest therapeutic intensity.
Conclusion: There are various IP antibiotics used for CAPD-P and the most common empirical therapy was the combination of ceftazidime and cefazolin while vancomycin is predominantly used for definitive therapy. Future studies to evaluate the clinical outcomes of the antibiotic use should be conducted to have a better insight on the efficacy of the peritonitis treatment.
METHODS: A retrospective record review of all CAPD patients on follow-up at the Miri Hospital, Sarawak, Malaysia from 2014 until 2017 was done.
RESULTS AND DISCUSSION: During the 4-year period, the overall peritonitis rate was 0.184 episodes per patient-year. Gram-positive and gram-negative bacteria each constituted one-third of the peritonitis; fungi (2.6%), Mycobacterium tuberculosis (MTB) (5.3%), polymicrobial (2.6%) and sterile culture (26.3%). The most commonly isolated gram-positive bacteria were coagulase-negative Staphylococcus. Our peritonitis rate is comparable to that of other centres i.e., Japan 0.195 and Indonesia 0.25. In comparison, countries like India (0.41), Korea (0.40) and Singapore (0.59) had relatively higher rate of PD-associated peritonitis. Two tuberculosis peritonitis patients died. The rate of catheter removal was approximately 20%. Gram-negative bacteria and MTB have a higher risk of catheter loss. About one-fifth used rainwater to clean their CAPD exit site. Out of this group, 33% did not boil the rainwater prior to usage.
CONCLUSION: Patient's characteristics and microbial susceptibility vary in different places of practice. The high rates of culture-negative peritonitis and high mortality risks associated with TB peritonitis warrant special attention. In patients with refractory peritonitis, early catheter removal is warranted in order to reduce mortality and minimize damage to peritoneal membrane.
