Renal function disorders in children with constitutional-exogenous obesity

Abstract

To compare blood creatinine levels in children with constitutionally exogenous obesity and in children without obesity. Materials and methods of research. The analysis of serum creatinine levels (Jaffe colorimetric method) was carried out in 162 children with constitutionally exogenous obesity, including overweight children, grade 1–4 obesity and 178 children of the control group who were treated in the Department of endocrinology of the Regional Children's Clinical Hospital of Astrakhan in the age range from one and a half to 17 years. The study period was more than 10 years. The criterion for exclusion from the study was the absence of concomitant pathology of the urinary system. The results and their discussion. When comparing serum creatinine levels in two groups of children (obese and non-obese), a significant increase was found in the group of children with constitutionally exogenous obesity. Thus, creatinine in the blood ≥ 120.0 mmol/l was recorded in 25 children out of 162 examined with constitutionally exogenous obesity and in 3 children out of 178 without obesity (χ 2 = 19.43; p < 0.00001). The highest serum creatinine levels were recorded in children with obesity of 1–2 degrees. Conclusion. Constitutionally exogenous obesity is associated with chronic impairment of nitrogen excretion function of the kidneys.
