Effect of Neutral-pH, Low-Glucose Degradation Product Peritoneal Dialysis Solutions on Residual Renal Function, Urine Volume, and Ultrafiltration: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background and objectives

Neutral-pH, low-glucose degradation products solutions were developed in an attempt to lessen the adverse effects of conventional peritoneal dialysis solutions. A systematic review was performed evaluating the effect of these solutions on residual renal function, urine volume, peritoneal ultrafiltration, and peritoneal small-solute transport (dialysate to plasma creatinine ratio) over time.

Design, setting, participants, & measurements

Multiple electronic databases were searched from January of 1995 to January of 2013. Randomized trials reporting on any of four prespecified outcomes were selected by consensus among multiple reviewers.

Results

Eleven trials of 643 patients were included. Trials were generally of poor quality. The meta-analysis was performed using a random effects model. The use of neutral-pH, low-glucose degradation products solutions resulted in better preserved residual renal function at various study durations, including >1 year (combined analysis: 11 studies; 643 patients; standardized mean difference =0.17 ml/min; 95% confidence interval, 0.01 to 0.32), and greater urine volumes (eight studies; 598 patients; mean difference =128 ml/d; 95% confidence interval, 58 to 198). There was no significant difference in peritoneal ultrafiltration (seven studies; 571 patients; mean difference =-110; 95% confidence interval, -312 to 91) or dialysate to plasma creatinine ratio (six studies; 432 patients; mean difference =0.03; 95% confidence interval, 0.00 to 0.06).

Conclusions

The use of neutral-pH, low-glucose degradation products solutions results in better preservation of residual renal function and greater urine volumes. The effect on residual renal function occurred early and persisted beyond 12 months. Additional studies are required to evaluate the use of neutral-pH, low-glucose degradation products solutions on hard clinical outcomes.

Project description:Background and objectivesResidual kidney function can be assessed by simply measuring urine volume, calculating GFR using 24-hour urine collection, or estimating GFR using the proposed equation (eGFR). We aimed to investigate the relative prognostic value of these residual kidney function parameters in patients on dialysis.Design, setting, participants, & measurementsUsing the database from a nationwide prospective cohort study, we compared differential implications of the residual kidney function indices in 1946 patients on dialysis at 36 dialysis centers in Korea between August 1, 2008 and December 31, 2014. Residual GFR calculated using 24-hour urine collection was determined by an average of renal urea and creatinine clearance on the basis of 24-hour urine collection. eGFR-urea, creatinine and eGFR β2-microglobulin were calculated from the equations using serum urea and creatinine and β2-microglobulin, respectively. The primary outcome was all-cause death.ResultsDuring a mean follow-up of 42 months, 385 (19.8%) patients died. In multivariable Cox analyses, residual urine volume (hazard ratio, 0.96 per 0.1-L/d higher volume; 95% confidence interval, 0.94 to 0.98) and GFR calculated using 24-hour urine collection (hazard ratio, 0.98; 95% confidence interval, 0.95 to 0.99) were independently associated with all-cause mortality. In 1640 patients who had eGFR β2-microglobulin data, eGFR β2-microglobulin (hazard ratio, 0.98; 95% confidence interval, 0.96 to 0.99) was also significantly associated with all-cause mortality as well as residual urine volume (hazard ratio, 0.96 per 0.1-L/d higher volume; 95% confidence interval, 0.94 to 0.98) and GFR calculated using 24-hour urine collection (hazard ratio, 0.97; 95% confidence interval, 0.95 to 0.99). When each residual kidney function index was added to the base model, only urine volume improved the predictability for all-cause mortality (net reclassification index =0.11, P=0.01; integrated discrimination improvement =0.01, P=0.01).ConclusionsHigher residual urine volume was significantly associated with a lower risk of death and exhibited a stronger association with mortality than GFR calculated using 24-hour urine collection and eGFR-urea, creatinine. These results suggest that determining residual urine volume may be beneficial to predict patient survival in patients on dialysis.

Project description:BackgroundIt has been noticed for years that ultrafiltration (UF) is important for survival in peritoneal dialysis. On the other hand, precise and convenient UF measurement suitable for patient daily practice is not as straight forward as it is to measure UF in the lab. Both overfill and flush before fill used to be source of measurement error for clinical practice. However, controversy finding around UF in peritoneal dialysis still exists in some situation. The current study was to understand the difference between clinical measured UF and real UF. The effect of evaporation and specific gravity in clinical UF measurement were tested in the study.MethodsFour different brands of dialysate were purchased from the market. The freshest dialysate available in the market were intentionally picked. The bags were all 2 L, 2.5% dextrose and traditional lactate buffered PD solution. They were stored in four different conditions with controlled temperature and humidity. The bags were weighted at baseline, 6 months and 12 months of storage. Specific gravity was measured in mixed 24 h drainage dialysate from 261 CAPD patients when they come for their routine solute clearance test.ResultsThere was significant difference in dialysate bag weight at baseline between brands. The weight declined significantly after 12 month's storage. The weight loss was greater in higher temperature and lower humidity. The dialysate in non-PVC package lose less weight than PVC package. The specific gravity of dialysate drainage was significantly higher than pure water and it was related to dialysate protein concentration.ConclusionStorage condition and duration, as well as the type of dialysate package have significant impact in dialysate bag weight before use. Evaporation is likely to be the reason behind. The fact that specific gravity of dialysate drainage is higher than 1 g/ml overestimates UF in manual exchanges, which contributes to systemic measurement error of ultrafiltration in CAPD.Trial registrationClinicalTrials.gov ID: NCT03864120 (March 8, 2019) (Understand the Difference Between Clinical Measured Ultrafiltration and Real Ultrafiltration).

Project description:BACKGROUND AND OBJECTIVES:Residual kidney function contributes to the clearance of antibiotics excreted by the kidneys, lowering the antibiotic concentration, which may adversely affect the treatment of peritoneal dialysis-associated peritonitis. The objective of our study was to examine the relationship between residual kidneyfunction and peritonitis treatment outcomes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS:Our study included 181 participants who experienced 339 episodes of Gram-positive, Gram-negative, and culture-negative peritoneal dialysis-associated peritonitis at a single centerfrom 2003 to 2010. Episodes were categorized according to participants' urinary creatinine clearance (0, >0-5, and >5 ml/min). The data were analyzed using generalized estimating equation models to determine the covariate-adjusted association between urinary creatinine clearance and treatment failure (defined as relapse or recurrent peritonitis episodes, peritoneal catheter removal, or death from any cause during peritonitis treatment). RESULTS:Among episodes of peritonitis due to Gram-positive organisms or culture-negative infections, those experienced by participants with urinary creatinine clearance >5 ml/min had significantly higher odds of treatment failure than episodes experienced by anuric participants (27 of 80 versus 20 of 119 episodes resulting in treatment failure for creatinine clearance >5 versus 0 ml/min; odds ratio, 6.80; 95% confidence interval, 2.37 to 19.6). Episodes experienced by participants with creatinine clearance >0-5 ml/min also had significantly higher odds of treatment failure than episodes experienced by anuric participants (14 of 64 episodes resulting in treatment failure for creatinine clearance >0-5 ml/min; odds ratio, 2.87; 95% confidence interval, 1.12 to 7.35). The odds of relapse and recurrent peritonitis among participants with creatinine clearance >5 ml/min was also significantly higher compared with in anuric participants (17 of 80 versus 12 of 119 episodes resulting in relapse and recurrence for creatinine clearance >5 versus 0 ml/min; odds ratio, 6.76; 95% confidence interval, 1.90 to 23.8). Among participants with Gram-negative peritonitis, creatinine clearance was significantly associated with neither treatment failure nor relapse and recurrent peritonitis. CONCLUSIONS:Residual kidney function as measured by greater urinary creatinine clearance was associated with treatment failure among participants with Gram-positive and culture-negative peritonitis.
