TNF-α, and its soluble form sTNFR1, as proinflammatory hormone plays a great role in pathogenesis of auto immunological diseases, insulin resistance, both carbohydrates and fat metabolism and development of late complications in type 1 diabetes mellitus (DMT1) patients.To asses TNF-α and sTNFR1 levels in children with DMT1 and to analyze the correlation with anthropometric parameters, metabolic control and the influence of the kind of insulin therapy.67 patients, aged from 3.71 to 14.81 years (mean±SD: 10.33±2.21). All the children were prepubertal (T ≰2), suffering for DMT1, without any coexisting diseases. The duration of the disease varied from 1.83 to 9 years (mean±SD: 4,0±1,6), and the age at diagnosis oscillated between 1.84 to 10.81 years. All the patients were divided into subgroups according to the kind of therapy which was not changed in the last 6 months. 15 agematched healthy children were included into the study. There were no statistically significant differences between the groups as to the metabolic control, age, weight, height and BMI.TNF-α levels in the study group ranged from 0.30 to 14.20 ng/ml (mean±1.62 ± 0.41 pg/ml) and were lower than in the control group: from 0.20 to 19.00 pg/ml (mean±SD: 1.67±1.41 pg/ml) (p0.05). The highest TNF-α levels were observed in the insulin pump group, lower in the multiple insulin injection group and in the conventional insulin therapy group. The sTNFR1 in the study group ranged from 707.00 to 1646.00 pg/ml (mean±SD: 1028.18±181.24 pg/ml) and was higher than in the control group: 613.0 to 1310.00 pg/ml (mean±SD: 978.00±203.03 pg/ml) (p0.05). The highest sTNFR1 levels were observed in the insulin pump group, lower in the multiple insulin injection group and the lowest in the conventional insulin therapy group.TNF-α levels are lower in DMT1 children, correlate only with height and do not depend on the kind of insulin therapy. sTNFR1 levels are higher in children with DMT1, correlate with anthropometric parameters and do not depend on the kind of insulin therapy. |
