Abstract
OBJECTIVES To study the effect of hypertensive disorders of pregnancy on peripheral venous blood cell count in preterm infants with a gestational age of 28-34 weeks. METHODS A total of 227 preterm infants with a gestational age of 28-34 weeks who were admitted to the Department of Pediatrics, the First Hospital Affiliated to Kunming Medical University, from January to December 2020, and whose mothers had hypertensive disorders of pregnancy were enrolled as the study group. A total of 227 preterm infants with a gestational age of 28-34 weeks who were admitted during the same period and whose mothers did not have hypertensive disorders of pregnancy were enrolled as the control group. According to maternal blood pressure during pregnancy, the study group was divided into three subgroups: gestational hypertension (n=75), mild preeclampsia (n=81), and severe preeclampsia (n=71). According to the birth weight of the preterm infants, the study group was divided into two subgroups: small for gestational age (SGA) (n=113) and appropriate for gestational age (AGA) (n=114). Peripheral blood cell count on day 1 after birth was compared between the study and control groups, as well as between the subgroups of the study group. RESULTS Compared with the control group, the study group had significantly lower white blood cell count, absolute neutrophil count, and blood platelet count (P<0.05) and significantly higher incidence rates of leucopenia and neutropenia (P<0.05). The subgroup analysis showed that the mild preeclampsia and severe preeclampsia subgroups had significantly lower white blood cell count, absolute neutrophil count, and blood platelet count than the gestational hypertension subgroup (P<0.05), and that the SGA subgroup had significantly lower white blood cell count, absolute neutrophil count, and blood platelet count than the AGA subgroup (P<0.05). CONCLUSIONS Hypertensive disorders of pregnancy can affect the peripheral venous blood cell count of preterm infants, which is more significant in infants with maternal preeclampsia and SGA infants.

Biomarkers of Inflammation and Redox Imbalance in Umbilical Cord in Pregnancies with and without Preeclampsia and Consequent Perinatal Outcomes. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:9970627. [PMID: 34795845 PMCID: PMC8595010 DOI: 10.1155/2021/9970627] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/06/2021] [Revised: 07/16/2021] [Accepted: 10/11/2021] [Indexed: 01/09/2023]
Abstract
OBJECTIVE To compare redox imbalance and inflammation biomarkers in umbilical cords from pregnancies with and without preeclampsia (PE) and to analyse their relationships with perinatal outcomes. METHODS A controlled cross-sectional study was conducted in Maceió, Alagoas, Brazil, that involved pregnant women with PE and a group of women without the disease, through the application of a standardized questionnaire. After delivery, umbilical cord samples were collected to measure antioxidant defense, products from oxidative damage, and inflammation biomarkers such as myeloperoxidase (MPO), interleukin- (IL-) 6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α). Statistical analyses were performed using Stata version 13.0 software and IBM Statistical Package for the Social Sciences (SPSS) 20.0, adopting a 95% confidence level (α = 0.05), with the chi-square test, the Wilcoxon-Mann-Whitney test, and the multinomial and Poisson regression tests. RESULTS One hundred PE pregnant women and 50 women without the disease were studied. The umbilical cords from PE pregnancies showed higher levels of reduced glutathione (GSH) (p ≤ 0.001), glutathione peroxidase (GPx) (p = 0.016), and malondialdehyde (MDA) (p = 0.028) and lower levels of IL-6 (p = 0.030) and TNF-α (p ≤ 0.001) than the other group, with some associations among these biomarkers with perinatal outcomes. CONCLUSION The higher levels of GSH and GPx, in addition to the lower levels of IL-6 and TNF-α, found in the PE umbilical cord, may result from adaptive mechanisms to maintain the oxidative and inflammatory balance; however, despite these changes, the damage to the cell membranes was not minimized, as the MDA level was higher in women with PE than in women without the disease. This implies that a redox imbalance is present, confirming that other physiological and adaptive mechanisms are being activated to preserve foetal health. Therefore, the present work unveils an important role of the umbilical cord in controlling redox imbalance and inflammation in PE pregnancies. Our results reinforce the necessity for continuous research on GSH as a protective compound for the perinatal outcome, especially in PE women.

Pak J Med Sci 2021; 37:1553-1557. [PMID: 34712281 PMCID: PMC8520365 DOI: 10.12669/pjms.37.6-wit.4828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 06/06/2021] [Accepted: 07/03/2021] [Indexed: 11/23/2022] Open
Abstract
Objectives: To study the expression of IL-17 in peripheral blood and its effect on maternal-fetal tolerance in patients with eclampsia in late pregnancy using MRI image segmentation algorithm. Methods: Thirty-nine patients with severe preeclampsia and eclampsia with brain symptoms were examined by cranial MRI. Pregnant women with 32 weeks of pregnancy were selected to detect the percentage of Th17 and Treg cells in CD4 + T lymphocytes and the expression of cytokines IL-17 and IL-10 in peripheral blood. Results: MRI examination was normal in 26 cases, 9 cases showed reversible posterior encephalopathy syndrome, three cases were cerebral hemorrhage, and one case was intracranial cavernous sinus thrombosis. two. Compared with the mild preeclampsia group, the relative number of Thl7 cells increased and that of Treg cells decreased in the severe preeclampsia group (P>0.05). Conclusion: The major types of cerebrovascular diseases (CVD) in severe preeclampsia and eclampsia were reversible posterior encephalopathy syndrome and cerebral hemorrhage. It was speculated that the damage to the blood-brain barrier may play an important role in the pathogenesis. The balance of the number of Th17 cells/the number of Treg cells was more inclined to the Th17 cell-mediated pro-inflammatory state, Treg cell-mediated immune tolerance decreases, and it becomes more obvious with the worsening of the disease.

NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2021; 394:2273-2287. [PMID: 34468816 DOI: 10.1007/s00210-021-02146-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 08/26/2021] [Indexed: 11/28/2022]
Abstract
Morbidity and mortality risks are enhanced in preeclamptic (PE) mothers and their offspring. Here, we asked if sexual dimorphism exists in (i) cardiovascular and renal damage evolved in offspring of PE mothers, and (ii) offspring responsiveness to antenatal therapies. PE was induced by administering NG-nitro-L-arginine methyl ester (L-NAME, 50 mg/kg/day, oral gavage) to pregnant rats for 7 days starting from gestational day 14. Three therapies were co-administered orally with L-NAME, atrasentan (endothelin ETA receptor antagonist), terutroban (thromboxane A2 receptor antagonist, TXA2), or α-methyldopa (α-MD, central sympatholytic drug). Cardiovascular and renal profiles were assessed in 3-month-old offspring. Compared with offspring of non-PE rats, PE offspring exhibited elevated systolic blood pressure and proteinuria and reduced heart rate and creatinine clearance (CrCl). Apart from a greater bradycardia in male offspring, similar PE effects were noted in male and female offspring. While terutroban, atrasentan, or α-MD partially and similarly blunted the PE-evoked changes in CrCl and proteinuria, terutroban was the only drug that virtually abolished PE hypertension. Rises in cardiorenal inflammatory (tumor necrosis factor alpha, TNFα) and oxidative (isoprostane) markers were mostly and equally eliminated by all therapies in the two sexes, except for a greater dampening action of atrasentan, compared with α-MD, on tissue TNFα in female offspring only. Histopathologically, antenatal terutroban or atrasentan was more effective than α-MD in rectifying cardiac structural damage, myofiber separation, and cytoplasmic alterations, in PE offspring. The repair by antenatal terutroban or atrasentan of cardiovascular and renal anomalies in PE offspring is mostly sex-independent and surpasses the protection offered by α-MD, the conventional PE therapy.

[Clinical features of very preterm small-for-gestational-age infants born due to severe preeclampsia]. ZHONGGUO DANG DAI ER KE ZA ZHI = CHINESE JOURNAL OF CONTEMPORARY PEDIATRICS 2021; 23. [PMID: 33691918 PMCID: PMC7969190 DOI: 10.7499/j.issn.1008-8830.2011006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Indexed: 01/23/2023]
Abstract
OBJECTIVE To study the clinical features of very preterm small-for-gestational-age infants born by cesarean section due to severe preeclampsia. METHODS Forty-two small-for-gestational-age infants who were admitted from August 2017 to July 2018 and were born due to severe preeclampsia were enrolled as the observation group. Forty very preterm infants who were born to healthy mothers since uterine contractions could not be suppressed were enrolled as the control group. Perinatal features, clinical manifestations of infection, complications, and clinical outcomes were analyzed for the two groups. RESULTS Within 6 hours and 2-3 days after birth, the observation group had significantly lower white blood cell count (WBC), absolute neutrophil count (ANC), and platelet count (PLT) than the control group (P < 0.05). At 5-7 days after birth, there was no significant difference in WBC between the two groups (P > 0.05), while the observation group still had significantly lower ANC and PLT than the control group (P < 0.05). The observation group had a significantly higher C-reactive protein (CRP) level than the control group at 2-3 days and 5-7 days after birth (P < 0.05). The observation group had a significantly higher proportion of infants with severe infections than the control group (P < 0.05). The observation group had a significantly higher hemoglobin level than the control group within 6 hours after birth (P < 0.05). The observation group had a significantly higher incidence rate of bronchopulmonary dysplasia than the control group (P < 0.05). There was no significant difference between the two groups in the rate of pulmonary hemorrhage, intracranial hemorrhage, neonatal necrotizing enterocolitis, retinopathy of prematurity, and the rate of use of invasive ventilation, and clinical outcomes (P > 0.05). CONCLUSIONS Very preterm small-for-gestational-age infants born due to severe preeclampsia have a high incidence rate of infection and severe conditions. Early manifestations include reductions in the infection indicators WBC, ANC, and PLT, and CRP does not increase significantly in the early stage and gradually increases at 2-3 days after birth. Most of these infants require invasive ventilation after birth, with bronchopulmonary dysplasia as the main complication. Clinical changes should be closely observed and inflammatory indicators should be monitored for early identification of infection, timely diagnosis, and timely adjustment of antibiotic treatment, so as to improve the outcome.
