Abstract

Introduction: Chronic kidney disease (CKD) in children, despite the progress in science and technology, is still a serious challenge. Early CKD detection gives a chance of early therapeutic intervention and lowering the progression of the disease. According to several publications indicating the possible use of alpha-Klotho (αKL) and tumour necrosis factor alpha (TNFα) for the early detection of the disease in adults, an attempt was made to evaluate their usefulness in the paediatric population.

Material and methods: The study group consisted of 42 patients with CKD with a mean age of 10.7 years (18 girls and 24 boys). The control group involved 21 healthy children with a mean age of 8.4 years (11 girls and 10 boys). Anthropometrical parameters and blood pressure were taken and routine biochemical tests were performed in the whole group. The concentrations of TNFα and αKL in serum and urine were determined by enzyme immunoassay.

Results: Children from the CKD group showed a statistically significant difference in serum TNFα and αKL in comparison to the control group. There was no significant relationship between the evaluated markers and sex, presence of hypertension, or proteinuria in the children. The mean αKL serum concentration was higher in patients on dialysis compared to the group of conservatively treated children, whereas the values of TNFα in serum and urine, as well as the αKL in urine, did not differ significantly in these groups. A significant positive correlation was found between serum αKL concentration and serum creatinine, but there was no other correlation between serum αKL or TNFα concentration and any of the measured anthropometric and laboratory parameters.

Conclusions: Serum TNFα and αKL levels in children with chronic kidney disease, although being statistically different compared to the group of healthy children, except for the correlation of serum aKL and creatinine, showed no other correlations to the most parameters used for chronic kidney disease evaluation including, eGFR. Their usefulness in the early detection of kidney dysfunction in children was not proven.
