The effect of the steroid profile on the severity and the outcome of treatment of newborns with congenital malformations

Abstract

Introduction. Adrenal insufficiency is often found in critical conditions of the neonatal period and has nonspecific symptoms, which greatly complicates its diagnosis. The objective was to study the hormonal status of newborns with congenital malformations (CM according to the outcome of treatment in the intensive care unit.Materials and methods. Study design – observational, dynamic retrospective comparative study. 60 newborns were examined: 26 healthy and 34 with CM. Depending on the severity of the condition, children with CM were divided into two groups. Group I included patients in an extremely severe condition, and in group II – in a stable condition. We studied the concentration of 17-hydroxypregnenolone, aldosterone, dehydroepiandrosterone, cortisol, cortisone, corticosterone, progesterone, testosterone, estradiol and 17-hydroxyprogesterone upon admission to the ICU, immediately after surgery and on the first day after it.Results. In all children with CM, the concentration of 17-hydroxypregnenolone, 17-hydroxyprogesterone, progesterone and dehydroepiandrosterone before surgery was significantly lower compared to healthy newborns, while in group I, it was minimal. After surgery, the concentration of cortisol precursors remained low, but its level increased significantly, especially in children of group I. A risk factor for lethal outcome in newborns with CM needing treatment in the ICU is the 17-OH-pregnenolone/dehydroepiandrosterone ratio, both at the time of admission to the ICU (AUC = 0.821; sensitivity = 68.97; specificity = 100; p = 0.0002; cut-off < 1,52); and on the first day after surgery (AUC = 0.807; sensitivity = 79.3; specificity = 80; р = 0.025; cut-off = 0).Conclusion. The increase in the concentration of cortisol against the background of low level of hormone precursors and the reduction of the 17-OH-pregnenolone/dehydroepiandrosterone ratio in the first day after surgery is a marker of an adverse course of the postoperative period and outcome.
