UK Renal Registry 18th Annual Report: Chapter 10 Clinical, Haematological and Biochemical Parameters in Patients Receiving Renal Replacement Therapy in Paediatric Centres in the UK in 2014: National and Centre-specific Analyses.

The median height z-score for paediatric patients on dialysis was −2.1 and for those with a functioning transplant −1.3. Children transplanted before the age of 12 years improved their height z-score over the subsequent five years, whereas those older than 12 maintained their height z-score, with all transplanted patients having a similar median height z-score after five years of starting renal replacement therapy (RRT). The median weight z-score for children on dialysis was −1.4 whereas children with a functioning transplant had a near normal weight for age and sex with a median z-score of −0.3. Of those with data, 75% of the prevalent paediatric RRT population had one or more ‘traditional’ risk factors for cardiovascular disease, with 1 in 10 having all three risk factors present. For the 10 centres reporting quarterly laboratory data, the average creatinine in transplant patients was 79 mmol/L; dialysis patients had normal average anaemia and acidosis markers and evidence of secondary hyperparathyroidism with an average PTH of 17.3 pmol/L. For transplant patients, 80% achieved the systolic blood pressure (SBP) standard and 93% achieved the haemoglobin standard. For haemodialysis patients, 57% achieved the SBP standard, 62% achieved the haemoglobin standard, 82% achieved the calcium standard, 51% achieved the phosphate standard and 39% achieved the parathyroid hormone (PTH) standard. For peritoneal dialysis patients, 70% achieved the SBP standard, 77% achieved the haemoglobin standard, 72% achieved the calcium standard, 54% achieved the phosphate standard and 33% achieved the PTH standard.
