The lead content in biological media term infants with hypoxic-ischemic CNS

Abstract

Introduction: The frequency of births of infants with perinatal pathology has increased in recent years. The aim of this study is to determination of lead content in the biomedias of newborns with hypoxic-ischemic damage of the central nervous system (CNS). Materials and Methods: We studied influence of the lead content in children, which were born with hypoxicischemic lesion CNS (HIL CNS). Determination of this microelement was carried out in the blood serum, erythrocytes and urine of 30 newborn infants which were suffered from asphyxia after birth. The comparison group consisted of 30 healthy full-term newborns. Results: In the biomedias of children with the HIL of the central nervous system, a toxic trace element of lead has been identified which is poorly retained in the placenta, so the fetus is more vulnerable to its toxic effects in the prenatal period. In the article the features of the lead content in serum, erythrocytes and urine in term infants which were born with hypoxic-ischemic CNS lesions are investigated. This group of subjects had increased serum and erythrocyte concentration of lead. The high content of lead in the erythrocytes of children with hypoxia which is already at birth may indicate a transplacental penetration of this toxic trace element and the possibility of its negative impact on the course of pregnancy. Conclusions: The prognostic significance of the lead content was high. Thus, the informative index (Ī) for lead content in serum is 7.40, and the prognostic factor (PC) is + 15.1. As for the prognostic value of the lead content in erythrocytes and urine, very high predictor properties are established for them: Ī = 7.44; PC = + 7.0 and Ī = 13.42; PC = + 16.1 respectively.
