Morphological features of kidneys in fetuses and newborns from mothers with subacute infectious-inflammatory process in the abdominal cavity caused by Escherichia coli (experimental study)
Background. In Ukraine, every year the number of women whose pregnancy occurs on the background of chronic infectious diseases increases. Escherichia coli is a frequent causative agent of bacterial infections in women. The purpose of the study was to identify the morphological features of fetuses and newborns kidneys from mothers with an experimental abdominal subacute infectious-inflammatory process caused by Escherichia coli. Materials and methods. The authors conducted an experiment on WAG rats, during which two groups were formed: group I — 7 fetuses and 11 newborns from 3 healthy females; group II — 10 fetuses and 13 newborns from 4 females with an abdominal infectious-inflammatory process in the abdominal cavity caused by Escherichia coli. The material of the study was the kidneys of fetuses and newborns. The authors used histological, histochemical, morphometric and statistical methods of investigation. Results. The abdominal subacute infectious-inflammatory process in the mother’s body caused by Escherichia coli leads to structural changes in the parenchymal and stromal components of the kidneys that have been growing from the fetus to the newborn. The glomerular apparatus of the kidneys is characterized by uneven distribution in the cortical layer, developmental delay, shape change, hemodynamic disorders, expansion of the urinary space, absence of capillaries, a decrease in the number and localization compactness of capillaries in some young and mature renal corpuscles; the tubular apparatus — developmental delay, shape change and focal thickening of the basal membranes of some tubules, focal dystrophic, necrotic and desquamative changes in the epithelium; stromal component — sclerotic changes, hemodynamic disorders, which were more pronounced in the medulla layer, cellular infiltration, characterized by the presence of fibroblastic cells and immune cells. Conclusions. Histological and morphometric changes in the fetuses and newborns kidneys developed due to the presence in mothers an experimental subacute infectious-inflammatory process in the abdominal cavity caused by Escherichia coli will lead to reduced functional abilities of the kidneys as a homeostatic organ and development of various nephrologic pathologies in such children.
