ГЛЮКОКОРТИКОСТЕРОИДНАЯ ТЕРАПИЯ И ФИЗИЧЕСКОЕ РАЗВИТИЕ ДЕТЕЙ СО СТЕРОИДЧУВСТВИТЕЛЬНЫМ НЕФРОТИЧЕСКИМ СИНДРОМОМ: РЕЗУЛЬТАТЫ РЕТРОСПЕКТИВНОГО ИССЛЕДОВАНИЯ

Abstract

Background. Body weight gain and growth retardation are common side effects of prolonged glucocorticosteroid  therapy in children. Time for the appearance  and elimination of glucocorticosteroid  obesity  as well as growth disorders  require further investigations. Objective .  Our aim was to study the relationship between glucocorticosteroid  therapy and changes in physical development indices of children with steroid-sensitive nephrotic syndrome (SSNS). Methods. We carried out a retrospective study of case records of patients with SSNS hospitalized in 2011–2014.  Treatment of children was carried out in accordance with the Federal Clinical Guidelines. The Z-score (ANTHRO Plus) was determined for body length (height), body weight, body mass index and correlation of physical development indices with a cumulative dose and duration of glucocorticosteroid  therapy. Results. We analyzed data on the treatment of 31 children, 18 of them received glucocorticosteroids  for 6 months (Group 1), 13 of them did not receive glucocorticosteroids       6 months (Group 2). The Z-score  of body weight in children in these groups was 1.64 ± 1.54 and 0.05 ± 1.19 (p = 0.004), Z-score  of body mass index was 1.85 ± 1.64 and -0.54 ± 1.14, respectively (p < 0.001). Excess body weight and obesity were only observed in children of Group 1 (in 6 and 9, respectively).  The Z-score  of the body length of patients in groups 1 and 2 were comparable and did not differ from normal values (0.34 ± 1.08 and 0.52 ± 1.12, respectively, p = 0.655). Correlation of Z-score values of the body length and cumulative doses of glucocorticosteroids was noted (r = -0.87, p < 0.001). Conclusion. Long-term (at least 6 months) glucocorticosteroid intake is associated with the development of overweight and obesity in most children with SSNS. In patients who did not use hormonal drugs for 6 months, normal body weight values were recorded. The height of children with SSNS was within the range of normal values.
