The aim of the study was to assess the carbohydrate and lipid metabolism disturbances as well as weight in children after brain tumors treatment.
The study included 33 boys (53.2%) and 29 girls (46.8%) aged 11.6 ± 3.9. 22 patients underwent treatment for tumors of hypothalamic-pituitary(h-p) area: IA–surgery(19/22); IB–surgery and radiotherapy(3/22). 40 patients were treated for tumors outside the h-p area: IIA– with surgery, chemo-and radiotherapy(22/40); IIB–only with surgery(15/40); IIC–patients treated for optic nerve glioma with chemotherapy(3/40).
BMI was assessed before and after the treatment. OGTT, HbA1c, lipid profile and WHtR after treatment were assessed. Indices of insulin resistance: HOMA-IR, Quickie, Matsuda and de Fronzo were calculated.
63% overweight/obese patients of IA-group and 27% of IIA-group were observed. Hyperinsulinemia was noted in 44% of IA-group, 20% of IIA-group, and insulin resistance in 38% of IA and 15% of IIA. DM2 was diagnosed in 1 patient of IA-group, IFG in 1 patient of IIB, IGT in 1 patient of IA and 1 patient of IIC. Dyslipidemia was noted in 47% of IA-group, elevated level of LDL-cholesterol in 30% of IIA-group.
The excessive weight gain, hyperinsulinemia and dyslipidemia were observed primarily in children treated for hypothalamic-pituitary tumors.
