Background and Objective: Intrauterine growth restriction (IUGR) poses additional challenges in extremely low gestational age newborns (ELGANs). We assessed disturbed hematopoiesis and morbidities associated with this disorder.Methods: This single-center retrospective case–control study compared perinatal hematological profiles, major morbidities, and mortality of 49 infants (gestational age <28 weeks, birth weight ≤ 3rd percentile, and compromised placental function) and 98 infants (birth weight >10th percentile) matched for gestational age, year, and sex.Results: IUGR-ELGANs had significantly elevated nucleated red blood cells and lower neutrophil and platelet counts at birth and on the third day of life. During the first week of life, IUGR-ELGANs received more red blood cell, platelet, and plasma transfusions and were more intensively treated with antibiotics. Rates of infections acquired during the first week (59.2 vs. 17.3%, p < 0.001), severe bronchopulmonary dysplasia or death (42.9 vs. 17.3%, p < 0.01), and mortality (36.7 vs. 7.1%, p < 0.001) were markedly elevated in IUGR-ELGANs, but not of hemorrhages or other morbidities.Conclusions: IUGR-ELGANs have high rates of acquired infections during the first week of life and display severe pulmonary morbidity leading to bronchopulmonary dysplasia or death. The high rate of transfusions observed in these infants warrants further scrutiny.

Pregnant women with intrauterine growth restriction (IUGR) have an increased risk of adverse perinatal and long-term complications compared with the birth of children with normal body weight. Thus, IUGR is one of the main challenges for the global health system, especially in poor and developing countries. Morpho-functional studies of the placentas help in determining the causes of IUGR, and therefore, timely prevent complications in pregnant women with IUGR. The objective: The purpose of this study is to investigate various morphometric and pathomorphological changes in the placenta, including inflammatory, in cases of IUGR, and to establish a correlation of these results with the etiology and complications for the fetus. Materials and methods. In the current study, 54 placentas of the fetuses with IUGR (the main group) were compared with 50 placentas of the fetuses with normal development (control group). The criteria for the inclusion of IUGR were gestational age more than 30 weeks and all fetuses with a weight less than 10th percentile for this period of pregnancy. The placenta material was studied pathomorphologically with laboratory screening for infection and inflammation. Similarly, the results were determined for placentas of the fetuses with normal development compared to placentas with IUGR. Results. The placenta study showed the presence of calcification in the case of IUGR, as well as in the case of prolonged pregnancy. However, calcification of the placenta in the case of IUGR was more progressive compared with placenta in the normal pregnancy. In addition, the presence of intrauterine infection and inflammation was observed, which could also lead to an adverse outcome for the further progression of pregnancy with IUGR. Conclusion. A comparative macro- and microscopic pathomorphological study of the placentas in the two groups has shown a significant increase in the pathological changes in all the anatomical structures of the fetuses with IUGR. Key words: Intrauterine growth restriction (IUGR), fetal weight, pathomorphological changes of the placenta.
