Abstract
Backgrоund. Osteoporosis is an important factor in the pathogenesis of orthopedic manifestations in children with cerebral palsy. It was previously demonstrated that children with cerebral palsy have specific changes in bone metabolism, which can cause changes in laboratory parameters compared with other orthopedic patients without neurological backgrounds.
Aim. The aim of this study was to assess bone metabolism biomarkers in children with cerebral palsy, identifying distinguishing characteristic patterns in comparison with patients with orthopedic pathology without neurological backgrounds.
Materials and methods. This study evaluated the concentrations of calcium, phosphorus, β-cross laps, osteocalcin, vitamin D, CICP, and alkaline phosphatase in the blood serum of 50 children with cerebral palsy aged between 6 to 12 years with GMFCS levels I–III. The control group consisted of 50 patients with plano-valgus deformities of the feet.
Results. The alkaline phosphatase activity in the group of children with cerebral palsy was 170.25 ± 59.35 u/L, while in the control group it was 145.58 ± 46.29 u/L; the CICP concentration in the study group was higher than in the control group (324.01 ± 174.10 and 269.68 ± 240.98, respectively). The concentration of β-cross laps, osteocalcin, calcium, and vitamin D in the study group was lower than in children with flat feet.
Conclusions. This study demonstrated multidirectional changes in the biomarkers of bone metabolism that are characteristic of walking children with cerebral palsy. These changes are characterized by a corresponding increase in the activity of osteoresorption and osteoreparation. This makes it possible to justify the combined use of metabolites and metabolic activators (calcium and vitamin D) and drugs that suppress osteoresorption (bisphosphonates) for the prevention and treatment of osteoporosis in children with cerebral palsy.
