The kidney complication of upper respiratory tract infection in preterm child of breast-feeding age

Abstract

The causes of children's morbidity and remote consequences are an important issue of the modern pediatric science. Taking into account the anatomical and functional features of premature infants, they need of a multidisciplinary approach in order to care and treat them. We suggest that the spreading of the clinical experience is helpful for the pediatric community to improve the practical skills and theoretical knowledge of the physicians. On the other hand, renal diseases are important causes of morbidity and mortality in children worldwide. Children born early or who are small for date newborns have relatively increased risk for the development of kidney injury later in life. They are often treated with medicines potentially inducing renal tissue injury.
In this paper, we have reporter a case in which 8-month-old child presented with a renal violations. The child had renal borderline states in the newborn period of the life. The breast-feeding was short. The respiratory support and warm protection were needed after birth. The physical development was estimated according to the Fenton chart due to 50 weeks of adjusted age of newborn. It was in the borders from 10 to 90 percentile. Fever, vomiting, dehydration and loss of bodyweight and oliguria appeared in the 8-months-old baby after the upper respiratory tract infection. General examine of patient showed the stigmas, delaying of neuropsychological growth, physical growth violations. Tests of blood identified anemia of the first stage and rapidly increasing of the level of white blood cells with the shift on the left the leukocyte formula and dyselectrolyte disorders in the blood. The laboratory tests of primary and secondary hemostasis were normal. The urine test showed a lot of changes of physical and chemical and also microscopic urine's properties. The sonography investigation diagnosed changes of renal tissue too and hyperplasia of the thymus. According to the data of patient's investigation acute urine tract infection — acute pielonephritis — was diagnosed and treated. That is why, physicians should focus attention on the stigmas, delaying of neuropsychological growth, physical growth violations and particulars of run neonatal and breast-feeding period of life, clinical signs and the results of additional investigations in order to get timely diagnosis.
Investigations were made according to the Declaration of Helsinki. The report of investigation was approved by the Local ethical committee of the institution. Informed consent was received from parents in order to make investigations.
