RESUMEN
Kidney failure has a negative impact on both children and families' quality of life (QOL). We evaluated the burden of home peritoneal dialysis (PD) using two local questionnaires and the French version of PedsQL3.0 end-stage kidney disease module and family impact module. Data are expressed as median (min-max). We reviewed the charts of 12 patients, at a median age of 8.8 (1.2-16.7) years, undergoing maintenance PD for 8 (1-42) months. Parathyroid hormone and haemoglobin levels were 215 (17-606) ng/L and 117 (104-141) g/L, respectively. Patients were taking 7 (3-10) different medications, corresponding to 9 (4-17) doses per day. The PD fluid volume per cycle was 1035 (723-1348) mL/m2 with a dwell duration of 75 (60-90) min and 6 (5-9) cycles per night. On a 2-week period, there were 2 (1-11) alarms per night resulting in 2 (0-8) times waking up and getting out of the bed for the parent(s); families were late 1 (0-11) times for school or parent's work. The time spent to connect and disconnect the cycler to the patient was 30 (12-46) min per day. QOL score on child self-report was correlated positively with weight percentile for age (R = 0.857; p = 0.014) and negatively with the number of siblings (R = -0.917; p = 0.004). The children QOL was evaluated higher by self-report scores: 77 (59-87) than by parent-proxy report scores: 53 (29-74), respectively (p = 0.028). PD children/teenagers and their caregivers can feel overwhelmed by the daily home therapy. Self-report and parent-proxy report QOL were significantly different, and it is questionable whether the parent-proxy report QOL relies rather on parents' own QOL.
RESUMEN
BACKGROUND: From 2006 to 2020, 24% of children starting haemodialysis in France weighed < 20 kg. Most new-generation long-term haemodialysis machines do not propose paediatric lines anymore but Fresenius has validated two devices for use in children above 10 kg. Our aim was to compare the daily use of these two devices in children < 20 kg. METHODS: Retrospective single-center evaluation of daily practice with Fresenius 6008® machines, and low-volume paediatric sets (83 mL), as compared to 5008® machines with paediatric lines (108 mL). Each child was treated randomly with both generators. RESULTS: A total of 102 online haemodiafiltration sessions were performed over 4 weeks in five children (median body weight 12.0 [range 11.5-17.0] kg). Arterial aspiration and venous pressures were maintained respectively over - 200 mmHg and under 200 mmHg. For all children, blood flow and volume treated per session were lower with 6008® vs. 5008® (p < 0.001), median difference between the two devices being 21%. In the four children treated in post-dilution mode, substituted volume was lower with 6008® (p < 0.001, median difference: 21%). Effective dialysis time was not different between the two generators; however, the difference between total duration of session and dialysis effective time was slightly higher (p < 0.05) with 6008® for three patients, due to treatment interruptions. CONCLUSION: These results suggest that children between 11 and 17 kg should be treated with paediatric lines on 5008® if possible. They advocate for modification of the 6008 paediatric set to decrease resistance to blood flow. The possibility to use 6008® with paediatric lines in children below 10 kg deserves further studies.
