Use of ClearGuard HD caps in pediatric hemodialysis patients.

BACKGROUND: Bloodstream infections (BSIs) are a leading cause of hospitalizations and mortality among patients receiving hemodialysis (HD) therapy, especially those with a central venous catheter (CVC) for dialysis access. The use of chlorhexidine impregnated catheter caps (ClearGuard) has been associated with a decrease in the rate of HD catheter-related BSIs (CA-BSIs) in adults; similar data have not been published for children. METHODS: We compared CA-BSI data from participating centers within the Standardizing Care to Improve Outcomes in Pediatric Endstage Kidney Disease (SCOPE) collaborative based on the center's use of ClearGuard caps for patients with HD catheter access. Centers were characterized as ClearGuard (CG) or non-ClearGuard (NCG) centers, with CA-BSI data pre- and post-CG implementation reviewed. All positive blood cultures in participating centers were reported to the SCOPE collaborative and adjudicated by an infectious disease physician. RESULTS: Data were available from 1786 SCOPE enrollment forms completed January 2016-January 2022. January 2020 served as the implementation date for analyzing CG versus NCG center data, with this being the time when the last CG center underwent implementation. Post January 2020, there was a greater decrease in the rate of HD CA-BSI in CG centers versus NCG centers, with a decrease from 1.18 to 0.23 and 0.41 episodes per 100 patient months for the CG and NCG centers, respectively (p = 0.002). CONCLUSIONS: Routine use of ClearGuard caps in pediatric dialysis centers was associated with a reduction of HD CA-BSI rates in pediatric HD patients.

Kidney Replacement Therapy in Low Birth Weight Preterm Newborns.

Managing newborns with kidney failure is a complex undertaking; even under ideal circumstances, dialysis is technically challenging and available therapies are designed for adults. These issues are exacerbated in smaller newborns, and intervention has traditionally not been offered in those below a certain weight threshold. Ethical concerns abound and patients deemed too small for dialysis are typically transitioned to comfort or palliative care. However, many of these neonates are otherwise healthy and would be considered survivable if kidney replacement therapy were available. To challenge the existing paradigm, we present 7 preterm, low birth weight neonates with end-stage kidney disease who were successfully managed using an innovative approach to kidney replacement therapy. These newborns had a median gestational age of 32 weeks (interquartile range [IQR], 32-35) and a median birth weight of 1.58 kg (IQR, 1.41-2.01). Kidney replacement therapy was initiated at a median age of 16 days (IQR, 1.5-40) and a weight of 1.85 kg (IQR, 1.57-2.1). Five of the 7 newborns (71%) survived to hospital discharge. Kidney replacement therapy was provided using 3F and 4F single lumen catheters and a modified ultrafiltration device. Patients experienced excellent metabolic control, and fluid homeostasis was achieved in the first week of life. Furthermore, survivors experienced physiologic weight gain and linear growth throughout their hospitalization. These findings, although preliminary, are encouraging for our smallest patients with kidney failure and suggest that survivability thresholds should be reexamined. At a minimum, neonatologists should be aware that novel approaches exist and may be considered for these challenging patients.
