Acta Paediatr 2024; 113:962-972. [PMID: 38265123 DOI: 10.1111/apa.17114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 01/03/2024] [Accepted: 01/10/2024] [Indexed: 01/25/2024]
Abstract
AIM This retrospective cohort study aimed to assess the utility of maternal C-reactive protein (CRP) and leukocyte levels in predicting neonatal sepsis after preterm premature rupture of membranes (pPROM). METHODS We conducted a retrospective cohort study (2009-2021), encompassing preterm infants born ≤29 + 6 weeks of gestation following pPROM. The primary outcome was early-onset neonatal sepsis within the initial 72 h of life. RESULTS We analysed data from 706 patients with a median gestational age at pPROM of 25.1 weeks and a median gestational age at birth of 26.4 weeks. Overall survival rate was 86.1%, with 65.7% survival without severe morbidities. These rates were significantly worse in preterm infants with sepsis. Maternal CRP and leukocyte levels correlated significantly with neonatal infection markers and sepsis. However, their predictive values, correlation coefficients, and area under the curve values were generally low. Using maternal CRP ≥2 mg/dL to predict neonatal sepsis yielded a positive predictive value of 18.5%, negative predictive value of 91.5%, AUC of 0.589, 45.5% sensitivity, and 74.5% specificity. CONCLUSION Maternal CRP and leukocyte levels were ineffective as a tool for predicting early-onset neonatal sepsis following early pPROM. Consequently, these biomarkers lack the reliability required for clinical decision-making in this context.

[PMID: 38671334 DOI: 10.1007/s00101-024-01405-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 02/29/2024] [Accepted: 03/14/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND Pregnant women with coronavirus disease 2019 (COVID-19) are at increased risk of severe disease progression. Comorbidities, such as chronic arterial hypertension, diabetes mellitus, advanced maternal age and high body mass index, may predispose to severe disease. The management of pregnant COVID-19 patients on the intensive care unit (ICU) is challenging and requires careful consideration of maternal, fetal and ethical issues. OBJECTIVE Description and discussion of intensive care treatment strategies and perinatal anesthesiological management in patients with COVID-19 acute respiratory distress syndrome (CARDS). MATERIAL AND METHODS We analyzed the demographic data, maternal medical history, clinical intensive care management, complications, indications and management of extracorporeal membrane oxygenation (ECMO) and infant survival of all pregnant patients treated for severe CARDS in the anesthesiological ICU of a German university hospital between March and November 2021. RESULTS The cohort included 9 patients with a mean age of 30.3 years (range 26-40 years). The gestational age ranged from 21 + 3 weeks to 37 + 2 weeks. None of the patients had been vaccinated against SARS-CoV‑2. Of the nine patients seven were immigrants and communication was hampered by inadequate Central European language skills. Of the patients five had a PaO2/FiO2 index < 150 mm Hg despite escalated invasive ventilation (FiO2 > 0.9 and a positive end-expiratory pressure [PEEP] of 14 mbar) and were therefore treated with repeated prolonged prone positioning maneuvers (5-14 prone positions for 16 h each, a total of 47 prone positioning treatments) and 2 required treatment with inhaled nitric oxide and venovenous ECMO. The most common complications were bacterial superinfection of the lungs, urinary tract infection and delirium. All the women and five neonates survived. All newborns were delivered by cesarean section, two patients were discharged home with an intact pregnancy and two intrauterine fetal deaths were observed. None of the newborns tested positive for SARS-CoV‑2 at birth. CONCLUSION High survival rates are possible in pregnant patients with CARDS. The peripartum management of pregnant women with CARDS requires close interdisciplinary collaboration and should prioritize maternal survival in early pregnancy. In our experience, prolonged prone positioning, an essential evidence-based cornerstone in the treatment of ARDS, can also be safely used in advanced stages of pregnancy. Inhaled nitric oxide (iNO) and ECMO should be considered as life-saving treatment options for carefully selected patients. For cesarean section, neuraxial anesthesia can be safely performed in patients with mild CARDS if well planned but the therapeutic anticoagulation recommended for COVID-19 may increase the risk of bleeding complications, making general anesthesia a more viable alternative, especially in severe disease.

Abstract
BACKGROUND Prediction of pregnancies at risk of preterm birth (PTB) may allow targeted prevention strategies. OBJECTIVES To assess quality of clinical practice guidelines (CPGs) and identify areas of agreement and contention in prediction and prevention of spontaneous PTB. SEARCH STRATEGY We searched for CPGs regarding PTB prediction and prevention in asymptomatic singleton pregnancies without language restriction in January 2024. SELECTION CRITERIA CPGs included were published between July 2017 and December 2023 and contained statements intended to direct clinical practice. DATA COLLECTION AND ANALYSIS CPG quality was assessed using the AGREE-II tool. Recommendations were extracted and grouped under domains of prediction and prevention, in general populations and high-risk groups. MAIN RESULTS We included 37 CPGs from 20 organizations; all were of moderate or high quality overall. There was consensus in prediction of PTB by identification of risk factors and cervical length screening in high-risk pregnancies and prevention of PTB by universal screening and treatment for asymptomatic bacteriuria, screening and treatment for BV in high-risk pregnancies, and use of preventative progesterone and cerclage. Areas of contention or limited consensus were the role of PTB clinics, universal cervical length measurement, biomarkers and cervical pessaries. CONCLUSIONS This review identified strengths and limitations of current PTB CPGs, and areas for future research.

[PMID: 38024217 PMCID: PMC10631574 DOI: 10.1055/a-2103-8143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 05/31/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction The aim of this study was to determine the extent to which regular monitoring of maternal free thyroxine level and pregnancy-adapted L-thyroxine replacement therapy before and during pregnancy in patients with existing or newly diagnosed latent and manifest hypothyroidism as well as hypothyroxinemia can influence the rate of premature births. Materials and Methods This is a retrospective cohort study assessing 1440 pseudonymized survey questionnaires to evaluate the risks of premature birth with two study groups from the same medical practice, and a nationally recruited control group. Study group A (n = 360) had already been taking L-thyroxine prior to conception, study group B (n = 580) started taking it after conception. Both study groups had a maximum gestational age of 12 + 0 GW. In the study groups, TSH and free thyroxine levels were determined regularly for dose adjustment purposes. The aim was to keep the free thyroxine level in the euthyroid hyperthyroxinemic range within the pregnancy adapted reference range. The control group (n = 500) had taken L-thyroxine during pregnancy according to criteria that were not known, as the questionnaire did not include any questions regarding this matter. Taking other risk factors into account, the influence of pregnancy-adapted L-thyroxine replacement therapy on the rate of premature births was determined using logistic regression analysis. Results Compared with the control group, the premature birth rate was 70% lower (p < 0.0001) in study group A and 42% lower in study group B (p = 0.0086), while the odds ratio, at 3.46, was particularly significant in study group A. High blood pressure (odds ratio 5.21), body mass index per kg/m 2 (odds ratio 0.91) and S. p. premature birth were identified as other independent risk factors. Conclusion The results show an association between more intensive thyroid diagnostics and pregnancy-adapted L-thyroxine replacement therapy and a decrease in premature births. Further studies should be conducted to confirm these results.

Possible Rates of Detection of Neonatal Sepsis Pathogens in the Context of Microbiological Diagnostics in Mothers - Real World Data. Geburtshilfe Frauenheilkd 2023; 83:1382-1390. [PMID: 37928410 PMCID: PMC10624541 DOI: 10.1055/a-2091-0856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 05/07/2023] [Indexed: 11/07/2023] Open
Abstract
Objective The aim of this study was to identify the rate of detection of neonatal sepsis pathogens in maternal microbiological smears. Study Design This is a retrospective study conducted at a Level 1 perinatal center in the context of routine care from 2014 to 2019. For all premature infants and neonates with neonatal sepsis, the neonatal and maternal microbiological findings were examined to see if there was a match. Results During the study period, a total of 948 premature or newborn infants were identified as having a neonatal infection. Among all of the premature or newborn infants, 209 (22%) met the diagnostic criteria for neonatal sepsis; of these, 157 were premature births and 52 were full-term births. We evaluated the microbiological findings for these 209 mother and child pairs. No pathogens were detected in 27 out of 157 mothers of premature infants (17.1%) and in 31 out of 52 mothers of full-term infants (59.6%). In the premature infant group there were pairs with matching pathogens in 30 out of 130 cases (23.1%, 95% CI: 16.1-31.3), and in the full-term infant group there was a match in 4 out of 21 cases (19%, 95% CI: 5.4-41.9). The number needed to test to have a 90% probability of success for pathogen detection varies between 9 and 11 in the most favorable case and 26 and 32 in the least favorable case, depending on the evaluation method. Conclusion In cases of neonatal sepsis, the sepsis-causing pathogen was successfully detected through prior analysis of a maternal smear in 7% of full-term infants and in 19% of premature infants. The number needed to test was relatively high in all groups. The value of maternal smears for identifying neonatal sepsis-causing pathogens needs to be critically questioned.

Abstract
Antiphospholipid syndrome (APS) is characterized by venous or arterial thrombosis and/or adverse pregnancy outcome in the presence of persistent laboratory evidence of antiphospholipid antibodies (aPLs). Preeclampsia complicates about 10-17% of pregnancies with APS. However, only early onset preeclampsia (<34 weeks of gestation) belongs to the clinical criteria of APS. The similarities in the pathophysiology of early onset preeclampsia and APS emphasize an association of these two syndromes. Overall, both are the result of a defective trophoblast invasion and decidual transformation at early gestation. Women with APS are at increased risk for prematurity; the reasons are mostly iatrogenic due to placental dysfunction, such as preeclampsia or FGR. Interestingly, women with APS have also an increased risk for preterm delivery, even in the absence of FGR and preeclampsia, and therefore it is not indicated but spontaneous. The basic treatment of APS in pregnancy is low-dose aspirin and low-molecular-weight heparin. Nevertheless, up to 20-30% of women develop complications at early and late gestation, despite basic treatment. Several additional treatment options have been proposed, with hydroxychloroquine (HCQ) being one of the most efficient. Additionally, nutritional interventions, such as intake of vitamin D, have shown promising beneficial effects. Curcumin, due to its antioxidant and anti-inflammatory properties, might be considered as an additional intervention as well.
