Prevention of peritonitis in children receiving peritoneal dialysis
Pediatric Nephrology, 2007
Peritonitis and catheter-related (exit-site/tunnel) infections are major causes of morbidity in children receiving peritoneal dialysis (PD). Our objective was to evaluate the impact of a combination of prophylactic measures on the rate of peritonitis and catheter-related infections subsequent to their implementation in 2001. This is a single center review of incident patients who received automated peritoneal dialysis (APD) from 1997 to 2004. The causal microorganisms, annualized peritonitis and catheter-related infections rates and the time to infection were reviewed using pooled data from 1997 to 2000 and from 2001 to 2004. Fifty-four patients received PD over 1099 patient months (pm). Twenty-eight peritonitis episodes occurred in 15 patients over 599 pm from 1997 to 2000 (annualized rate (AR): 0.56 infections/patient year). Eight episodes of peritonitis occurred in five patients over 500 pm from 2001 to 2004 (AR: 0.19 infections/patient year) (P = 0.01). Prior to 2001, the median time from dialysis initiation to the first peritonitis episode was 500 days (95% CI, 400–660 days), compared to 1137 days (95% CI, 1050 to +Infinity) from 2001 to 2004 (P = 0.008). The rate of catheter-related infections and time to initial infection during the two periods was not different. We conclude that measures to decrease the frequency of peritonitis can be successfully applied to children and should be incorporated as part of standard care.

In children who are on chronic peritoneal dialysis, peritonitis is the primary complication compromising technique survival, and the optimal therapy of peritonitis remains uncertain. An Internet-based International Pediatric Peritonitis Registry was established in 47 pediatric centers from 14 countries to evaluate the efficacy and safety of largely opinion-based peritonitis treatment guidelines in which empiric antibiotic therapy was stratified by disease severity. Among a total of 491 episodes of nonfungal peritonitis entered into the registry, Gram-positive organisms were cultured in 44%, Gram-negative organisms were cultured in 25%, and cultures remained negative in 31% of the episodes. In vitro evaluation revealed 69% sensitivity of Grampositive organisms to a first-generation cephalosporin and 80% sensitivity of Gram-negative organisms to a third-generation cephalosporin. Neither the risk factors assumed by the guidelines nor the choice of empiric therapy was predictive of either the early treatment response or the final functional outcome of the peritonitis episodes. Overall, 89% of cases achieved full functional recovery, a portion after relapsing peritonitis (9%). These data serve as the basis for new evidence-based guidelines. Modification of empiric therapy to include aminoglycosides should be considered.
Gram-Negative Peritonitis in Children Undergoing Long-term Peritoneal Dialysis
American Journal of Kidney Diseases, 2008
The proportion of gram-negative causative organisms in peritoneal dialysisassociated peritonitis is increasing. Little published information for this complication exists in children. The objective of this study is to evaluate the clinical presentation, early and late response to treatment, and identification of factors influencing the outcome of gram-negative peritonitis (GNP) in children. Study Design: Case series. Setting and Participants: 104 children (aged 7.9 Ϯ 5.9 years) with 121 GNP episodes reported to the International Pediatric Peritonitis Registry from October 2001 through December 2004. Predictors: Patient, clinical, bacteriological, and treatment features. Outcomes: Initial response to empirical treatment was assessed after approximately 72 hours of therapy. Final outcome was judged according to the occurrence of death, technique failure, relapse, need for catheter exchange, and a composite end point defining full functional recovery.
Risk Factors Associated with Nosocomial Peritonitis in Children on Peritoneal Dialysis
Revista de investigación clínica; organo del Hospital de Enfermedades de la Nutrición
Peritoneal dialysis is the most frequent dialysis method in children, and peritonitis is a frequent complication. The responsible organisms differ between nosocomial and community acquired peritonitis, they cause longer hospitalization time, and can lead to dialysis failure. The aim of the study was to describe the risk factors associated with nosocomial peritonitis in children with end-stage renal disease undergoing dialysis treatment. A nested case-control study was conducted in an academic medical center. The basic cohort included all pediatric patients with end-stage renal disease undergoing continuous ambulatory peritoneal dialysis therapy and who were hospitalized for non-infectious causes during the study period, January 2008 to December 2009. Cases were subjects who developed nosocomial peritonitis during hospitalization, and controls were children free of nosocomial peritonitis. The final groups consisted of 10 cases and 35 controls. There were 11 episodes of nosocomial per...
Risk factors for peritonitis in pediatric peritoneal dialysis: a single-center study
Pediatric Nephrology, 2005
Recent US registry data and a European multicenter study described increased risk of peritonitis in young children on peritoneal dialysis (PD). No underlying age-specific risk factors could be defined in these reports. Therefore, we analyzed risk factors for peritonitis in children treated by PD as primary renal replacement therapy at the Kinderdialyse, Vienna, and particularly searched for age-specific aspects. Thirty children (15 boys, mean age 4.6 years) received PD [21 automated peritoneal dialysis (APD), nine continuous ambulatory peritoneal dialysis (CAPD)] for 13 months (3-49 months). During the total observation period of 395 dialysis months, 27 peritonitis episodes were diagnosed (1:14.6 months or 0.82/patient per year). Of our population, 43% remained peritonitis free; seven patients suffered from more than one peritonitis episode. Ten potential risk factors [age, gender, PD modality, duration of PD, exit-site status, urine volume, residual glomerular filtration rate (GFR), Kt/V, normalized protein catabolic rate (nPCR), albumin] and four indices of peritonitis outcome (peritonitis incidence, peritonitis burden, risk of suffering more than one episode of peritonitis and chance of staying free from peritonitis) were analyzed. Our study identified six risk factors in univariate analysis, namely age, APD treatment, exit-site infections, low urinary volume, low residual GFR and low nPCR, which were significantly correlated with two or more of the outcome indices. Multivariate analysis identified exit-site infection and residual urine volume as strong independent predictors. In summary, our study identified several age-dependent and age-independent risk factors for peritonitis in pediatric PD. These data demonstrate that the risk for peritonitis in small children is not pre-determined but might be open to therapeutic interventions, such as optimizing exit-site care, dialysis prescription and nutrition management.
Prevention of Peritonitis in Children on Peritoneal Dialysis
2000
We reviewed methods of preventing peritonitis in children. A considerable body of evidence indicates that peritonitis rates are lowest with the use of a double-cuffed catheter, with a downward directed tunnel, placed by an experienced surgeon. Evidence in adults, but lacking in children, suggests that exit-site mupirocin will lower Staphylococcus aureus exit-site infections and thus peritonitis rates. The risk of peritonitis due to contamination can be diminished by the avoidance of spiking and by the provision of a long training period. Catheter removal and replacement for catheter-related peritonitis may be done simultaneously in certain circumstances and is useful in decreasing the risk of recurrent peritonitis. Antibiotic prophylaxis at the time of catheter insertion, for contamination, during dialysate leaks, and for invasive procedures appears to be useful in diminishing peritonitis risk.
Worldwide variation of dialysis-associated peritonitis in children
Kidney International, 2007
Peritonitis is the most common cause of dialysis failure in children on chronic peritoneal dialysis. We performed a prospective study of 501 peritonitis episodes in 44 pediatric dialysis centers located in 14 countries that examined peritonitis etiology, efficiency of opinion-based management guidelines, and final outcomes. Culture-negative incidence varied significantly from 11% in North America to 67% in Mexico. Argentina and North America had the highest rate of Gram-negative episodes. Pseudomonas-based peritonitis was eightfold more common in the United States than in Europe, and correlated with the frequency of exit site cleansing and topical mupirocin administration. Significant regional variation in antibiotic susceptibility was noted for the first generation cephalosporins and aminoglycosides. Initial response rates to standardized empiric antibiotic treatment did not differ between regions; however, final outcomes were significantly less favorable in Eastern Europe. The wide regional variation in culture-negative peritonitis, and the distribution and antibiotic susceptibilities of causative bacteria needs to be taken into consideration when the guidelines for empiric therapy of pediatric dialysis-associated peritonitis are revised.

Background : The aim of the present study was to perform a multicenter investigation in Turkish children on chronic peritoneal dialysis by examining the rates of peritonitis as well as causative organisms according to year . Methods : Twelve pediatric renal units participated in this study and data were obtained by review of the medical records. Results : One hundred and thirty-two patients were on continuous ambulatory peritoneal dialysis (CAPD), 21 were on automated peritoneal dialysis (APD) and 59 were on CAPD and APD at different times. Mean durations of CAPD and APD were 24.2 ± 21.1 months and 22.9 ± 12.8 months, respectively. Seventy-one (33%) out of 212 patients had no peritonitis episode. Overall peritonitis rate was one episode per 15.5 patient-months. The peritonitis rate was one episode per 15.4 patient-months for APD and one episode per 15.6 patient-months for CAPD. Coagulase-negative staphylococcus was the most common cause of peritonitis among patients with positive culture (20.6%). While the incidence of Gram-negative infection remained unchanged according to year in patients on CAPD ( P ϭ 0.68), the rate of Gram-negative peritonitis in children on APD was signifi cantly higher ( P ϭ 0.03). Conclusions : Peritonitis rate was similar in CAPD and APD, but the risk of Gram-negative peritonitis in APD was higher than that of CAPD.
