Characteristics of adverse side effects of corticosteroid therapy in children with nephrotic syndrome and methods of pharmacological correction

Abstract

Introduction: The article discusses the issues of the long-term glucocorticosteroid therapy in children with nephrotic syndrome that results in severe adverse side effects.

Methods: This retrospective study included 89 case reports of patients with nephrotic syndrome, aged 1–18, who received treatment at Voronezh Regional Pediatric Hospital №1 in 1999–2014. The children’s BMI Z-score was calculated from neasured height and weight. The authors considered therapeutical complications revealed through clinical-laboratory and instrumentation examination.

Results and discussion: Long-term administration of glucocorticosteroids in patients with steroid-dependent nephrotic syndrome caused overweight and obesity. The patients who had received glucocorticosteroids for 6 months prior to the examination were overweight or obese (78%), had reactive pancreatitis (72%), leukemoid reactions (67%), liver damage (50%), Cushing’s syndrome (44%), chronic gastroduodenitis (33%), hyperglycemia (11%), arterial hypertension (6%), or infectious diseases (6%). The children observed during the period of prolonged remission of nephrotic syndrome had neither overweight, nor obesity or growth failure; signs of chronic gastroduodenitis were observed in 15% of the children.

Conclusion: The long-term glucocorticosteroid therapy in children with nephrotic syndrome caused the excess body weight or obesity and gastro-intestinal disorders. So, proton pump inhibitors should be applied simultaneously with glucocorticosteroids to prevent gastro-intestinal disorders
