Abstract
Assess creatinine levels in French children with Down syndrome (DS) on the basis of the relationship between creatinine levels and age. The study included 279 children with DS aged 0 to 10 years who had been regularly monitored between 2004 and 2021 in a single genetics department and who had had at least one creatinine measurement. The creatinine level curves were established by estimating the median and the quantiles of order 2.5 and 97.5% according to age. A Generalized Additive Model for Location, Scale, and Shape was used. The results showed higher creatinine levels in children with DS than in children from the general population.
Conclusion: The present results allow to propose an original chart of creatinine levels according to age in French children with DS, which should help optimize their medical management and improve the early detection of renal diseases.
What is Known: • Creatinine is a product of muscle breakdown and depends on muscle mass and children with Down syndrome have muscle and growth characteristics that differ from those of the general paediatric population. • Serum creatinine values in Japanese children with DS are higher than those of children from the general Japanese population. | |
What is New: • Creatinine values in French children with DS are higher than those of children from the general French population. • The proposed original chart for creatinine values according to age, specifically designed for individuals up to 10 years old, should serve for further investigation, prevention, and follow-up of children with DS. |
