Abstract
INTRODUCTION Intraamniotic infection (IAI) and subsequent early-onset neonatal sepsis (EONS) are among the main complications associated with preterm prelabor rupture of membranes (PPROM). Currently used diagnostic tools have been shown to have poor diagnostic performance for IAI. This study aimed to investigate whether the exposure to IAI before delivery is associated with short-term variation of the fetal heart rate in pregnancies with PPROM. METHODS Observational cohort study of 678 pregnancies with PPROM, delivering between 24 + 0 and 33 + 6 gestational weeks from 2012 to 2019 in five labor units in Stockholm County, Sweden. Electronic medical records were examined to obtain background and exposure data. For the exposure IAI, we used the later diagnosis of EONS in the offspring as a proxy. EONS is strongly associated to IAI and was considered a better proxy for IAI than the histological diagnosis of acute chorioamnionitis, since acute chorioamnionitis can be observed in the absence of both positive microbiology and biochemical markers for inflammation. Cardiotocography traces were analyzed by a computerized algorithm for short-term variation of the fetal heart rate, which was the main outcome measure. RESULTS Twenty-seven pregnancies were categorized as having an IAI, based on the proxy diagnosis of EONS after birth. Fetuses exposed to IAI had significantly lower short-term variation values in the last cardiotocography trace before birth than fetuses who were not exposed (5.25 vs 6.62 ms; unadjusted difference: -1.37, p = 0.009). After adjustment for smoking and diabetes, this difference remained significant. IAI with a later positive blood culture in the neonate (n = 12) showed an even larger absolute difference in STV (-1.65; p = 0.034), with a relative decrease of 23.5%. CONCLUSION In pregnancies with PPROM, fetuses exposed to IAI with EONS as a proxy have lower short-term variation of the fetal heart rate than fetuses who are not exposed. Short-term variation might be useful as adjunct surveillance in pregnancies with PPROM.

Prolonged premature rupture of membranes with increased risk of infection is associated with gut accumulation of Pseudomonas from the environment. Comput Struct Biotechnol J 2024; 23:2851-2860. [PMID: 39100803 PMCID: PMC11296040 DOI: 10.1016/j.csbj.2024.07.007] [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: 03/14/2024] [Revised: 07/04/2024] [Accepted: 07/05/2024] [Indexed: 08/06/2024] Open
Abstract
Background Preterm premature rupture of membranes (PPROM) contributes to over one-third of preterm births, and PPROM infants are more susceptible to infections. However, the risk factors remain poorly understood. We here aim to investigate the association of duration of premature rupture of membranes (PROM) and environmental microbiota with the gut microbiota and infection in PPROM infants. Methods Forty-six premature infants were recruited from two hospitals, and infant fecal and environmental samples were collected. 16 s rRNA sequencing was performed to analyze the fecal and environmental microbiome. Human inflammatory cytokines in cord vein plasma were measured. Results The gut microbiota composition of PPROM infants was different from that of non-PPROM infants, and the microbiome phenotypes were predicted to be associated with a higher risk of infection, further evidenced by the significantly increased levels of IL-6 and IL-8 in cord vein plasma of PPROM infants. The diversity of the gut microbiota in PPROM infants increased significantly as the duration of PROM excessed 12 h, and Pseudomonas contributed significantly to the dynamic changes. The Pseudomonas species in the gut of PPROM infants were highly homologous to those detected in the ward environment, suggesting that prolonged PROM is associated with horizontal transmission of environmental pathogens, leading to a higher risk of infection. Conclusions This study highlights that the duration of PROM is associated with the accumulation of environmental pathogens in the gut of PPROM infants, which is a risk factor for nosocomial infections. Improving environmental hygiene could be effective in optimizing the clinical care of PPROM infants.

Abstract
CONTEXT This study aimed to study feto-maternal outcomes in women with preterm prelabor rupture of membranes (PTPROM) on expectant management versus delivery at 34 weeks of gestation and correlate the period of latency and inflammatory markers with delivery outcomes. We have chosen this research topic as there is a paucity of specific guidelines regarding the optimal period of gestation for delivering women with PTPROM. AIM The study correlated the feto-maternal outcomes in women with PTPROM on expectant management till 37 weeks versus delivery at 34 weeks with a period of latency and maternal inflammatory markers. METHODS AND MATERIALS This was a prospective observational study conducted on 262 women with PTPROM from 28-33+6 weeks of gestation. Women were monitored till 37 weeks with biweekly total leukocyte count and weekly C-reactive protein, urine routine microscopy, urine culture, high vaginal culture sensitivity, and ultrasound. Women were monitored expectantly till 37 weeks. However, intervention was done at any time during the feto-maternal compromise. There were 52 women who delivered <34 weeks and 210 women who delivered ≥34 weeks. Feto-maternal outcomes were documented. Group A was assigned to women who delivered before 34 weeks and Group B was assigned to women who delivered after 34 weeks. Statistical analysis was done using SPSS software. A p-value <0.05 was considered significant. RESULTS Among the study group, 238 (90.8%) women were managed expectantly while 24(9.1%) required intervention. A latency of 3-4 weeks was observed in 131(50%) women. Chorioamnionitis developed in 7 women (4.4%) in group A and 13 women (4.9%) in group B. Neonates developed sepsis in 5.7% in group A and 5.8 % in group B and were comparable in both the groups (p=1.000). Early neonatal death (END) occurred in 10 (3.8%) among which seven died because of low birth weight (LBW), two due to sepsis, and one due to respiratory distress. LBW was significantly associated with END (p<0.001) Conclusion: Expectant management beyond 34 weeks with close monitoring can improve neonatal outcomes without increasing maternal morbidity in women with PTPROM.

Abstract
OBJECTIVE To discuss the correlation between serum progesterone, glycosylated Hemoglobin (HbA1c), and insulin levels in pregnant women with Gestational Diabetes Mellitus (GDM) and the risk of Premature Rupture of Membranes (PROM). METHODS A retrospective analysis was conducted on 52 patients diagnosed with GDM who also presented with PROM (Observation group) and compared with 89 patients diagnosed with GDM but not complicated with PROM (Control group). Progesterone, insulin, and HbA1c were detected. Risk factors for PROM in GDM patients were analyzed. RESULTS The observation group had higher HbA1c and fasting blood glucose levels. Poor blood glucose control and GWG are risk factors for PROM in GDM patients. PROM increases adverse pregnancy outcomes in GDM. HbA1c, insulin, and HOMA-IR can predict the risk of PROM in GDM. CONCLUSIONS The effective prediction of preterm PROM can be achieved through the monitoring of serum HbA1c, insulin levels, and insulin resistance in patients with GDM.

Abstract
OBJECTIVE The benefit of mechanical ripening agents following preterm premature rupture of membranes (PPROM) has not been established. We sought to compare the time to delivery in women who received transcervical Foley catheter plus oxytocin infusion versus oxytocin infusion alone in patients with unfavorable cervices and PPROM. STUDY DESIGN This is a retrospective cohort study of patients presenting with PPROM of a live, singleton gestation between 240/7 and 366/7 weeks' gestation from January 2005 to October 2018 at a single, tertiary care institution. Patients with an unfavorable cervical examination (≤2-cm dilation), no contraindication to labor and undergoing labor induction were analyzed. Time to delivery was analyzed using multivariable linear regression adjusting for cervical dilation at induction and nulliparity. Bivariate and multivariate analyses were used where appropriate. RESULTS A total of 260 participants were included: 109 who received a Foley catheter and oxytocin (Foley/oxytocin) and 151 who had oxytocin alone. Demographic characteristics were similar between the two groups. Unadjusted time to delivery was significantly shorter in the oxytocin only group (Foley/oxytocin: 20.35 hours vs. oxytocin alone: 14.7 hours, p < 0.001). No differences in length of labor were detected after adjusting for cervical dilation at induction and nulliparity (p = 0.5). The unadjusted rate of cesarean delivery was higher in the combination Foley/oxytocin group (Foley/oxytocin: 16.5% vs. oxytocin alone: 7.3%, p = 0.03), but no differences were found in the adjusted analysis (p = 0.06). There were no differences in clinical chorioamnionitis rates between the two groups (Foley/oxytocin: 8.3% vs. oxytocin alone: 9.3%, p = 0.83). Furthermore, no significant differences were found in maternal and neonatal outcomes between the two groups. CONCLUSION In patients with PROM, the use of a transcervical Foley catheter in addition to oxytocin is not associated with a shorter time to delivery compared with oxytocin alone. KEY POINTS · Transcervical Foley catheter did not shorten length of labor in PPROM.. · Transcervical Foley catheter did not increase infection risk.. · Pitocin alone can be used in PPROM population..

Abstract
BACKGROUND Preterm prelabor rupture of membranes (PPROM) is a frequent obstetrical condition with risks of maternal and neonatal morbidity and mortality. Home hospitalization (HH) management is an alternative to conventional hospitalization (CH) which remains controversial, and there has been little study of eligibility criteria. OBJECTIVE To study obstetrical and perinatal outcomes of PPROM between 24 and 34 gestational weeks in patients discharged to homecare after 4 days, based on a policy of expanded discharge criteria. STUDY DESIGN AND SETTING Retrospective before-and-after study over 10 years in a single French level III perinatal center. In period A (2009-2013), discharge criteria were restrictive and in period B (2015-2019), more extended discharge criteria were adopted. The primary outcome was the incidence of confirmed early-onset neonatal sepsis (EOS). RESULTS The proportion of patients discharged to home hospitalization increased from 28/170 (16.5) in period A to 39/114 (34.2) in period B (p < 0.01). Regarding the primary outcome, no statistically significant difference in EOS rates was observed between periods (11/153 (7.1) vs 5/110 (4.5), p = 0.37). The incidence of a composite outcome combining severe perinatal complications (intrauterine fetal demise, placental abruption and cord prolapse) did not significantly increase during period B (7/170 (4.1) vs 4/114 (2.7), p = 0.37). There was no significant difference between the periods for chorioamniotitis (9.41% in period A and 11.4% in period B, p = 0.58). CONCLUSION Severe maternal or neonatal complications rates did not increase when criteria for home hospitalization were expanded. Larger, prospective studies are needed to confirm the results of such a strategy.

Abstract
OBJECTIVE To investigate reliable biomarkers for predicting histological chorioamnionitis (HCA) in women with preterm prelabour rupture of membranes (PPROM). DESIGN A retrospective study. SETTING A maternity care hospital in Shanghai. POPULATION Women with PPROM before 34+0/7 weeks of gestation. METHODS Mean values of biomarkers were compared by two-way analysis of variance (ANOVA). Log-binomial regression models were used to assess the association between biomarkers and risk of HCA. A stepwise logistic regression model was used to develop a multi-biomarker prediction model and identify the independent predictors. The area under the receiver operating characteristic curve (AUC) was used to assess prediction performance. MAIN OUTCOME MEASURES The ability of the individual biomarker and the combination of multiple biomarkers to predict HCA. RESULTS In 157 mothers with PPROM, 98 (62.42%) women had HCA and 59 (37.58%) women did not have HCA. No significant differences were observed between the two groups in white blood cell, neutrophil or lymphocyte counts, whereas both high-sensitivity C-reactive protein (hsCRP) and procalcitonin (PCT) were significantly higher in the HCA group. HsCRP and PCT were found to be independently associated with the risk of HCA, and PCT had a larger AUC value than hsCRP (p < 0.05). The optimal multi-biomarker prediction model for HCA (AUC = 93.61%) included hsCRP at 72 hours and PCT at 48 and 72 hours, and PCT had a stronger prediction capacity than hsCRP. CONCLUSIONS PCT could be a reliable biomarker for the early prediction of HCA in women with PPROM within 72 hours of dexamethasone treatment.

Abstract
Background: Prelabor rupture of membranes (PROM) is associated with maternal and neonatal infections. Although guidelines suggest prophylactic antibiotics for pregnant women with PROM, the optimal antibiotic regimen remains controversial. Synthesizing the data from different studies is challenging due to variations in reported outcomes. Objective: This study aimed to form the initial list of outcomes for the core outcome set (COS) that evaluates antibiotic use in PROM by identifying all existing outcomes and patients' views. Methods: Relevant studies were identified by searching PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, and VIP databases. We also screened the references of the included studies as a supplementary search. We extracted basic information from the articles and the outcomes. Two reviewers independently selected the studies, extracted the data, extracted the outcomes, and grouped them into domains. Then, semi-structured interviews based on the potential factors collected by the systematic review were conducted at West China Second Hospital of Sichuan University. Pregnant women who met the diagnostic criteria for PROM were enrolled. Participants reported their concerns about the outcomes. Two researchers identified the pregnant women's concerns. Results: A total of 90 studies were enrolled in this systematic review. The median outcomes in the included studies was 7 (1-31), and 109 different unique outcomes were identified. Pre-term PROM (PPROM) had 97 outcomes, and term PROM (TPROM) had 70 outcomes. The classification and order of the core outcome domains of PPROM and TPROM were consistent. The physiological domain was the most common for PPROM and TPROM outcomes. Furthermore, 35.1 and 57.1% outcomes were only reported once in PPROM and TPROM studies, respectively. Thirty pregnant women participated in the semi-structured interviews; 10 outcomes were extracted after normalized, and the outcomes were reported in the systematic review. However, studies rarely reported pregnant women's concerns. Conclusion: There was considerable inconsistency in outcomes selection and reporting in studies about antibiotics in PROM. An initial core outcomes set for antibiotics in PROM was formed.

Abstract
According to current guidelines, inpatient management until birth is considered standard in pregnant women with preterm premature rupture of membranes (PPROM). With the increasing burden on
obstetric departments and the growing importance of satisfaction and right to self-determination in pregnant women, outpatient management in PPROM is a possible alternative to inpatient
monitoring. The most important criterion for this approach is to ensure the safety of both the mother and the child. Due to the small number of cases (n = 116), two randomised controlled
trials (RCTs) comparing inpatient and outpatient management were unable to draw any conclusions. By 2020, eight retrospective comparative studies (cohort/observational studies) yielded the
following outcomes: no significant differences in the rate of maternal complications (e.g., chorioamnionitis, premature placental abruption, umbilical cord prolapse) and in neonatal
morbidity, significantly prolonged latency period with higher gestational age at birth, higher birth weight of neonates, and significantly shorter length of stay of preterm infants in
neonatal intensive care, shorter hospital stay of pregnant women, and lower treatment costs with outpatient management. Concerns regarding this approach are mainly related to unpredictable
complications with the need for rapid obstetric interventions, which cannot be performed in time in an outpatient setting. Prerequisites for outpatient management are the compliance of the
expectant mother, the adherence to strict selection criteria and the assurance of adequate monitoring at home. Future research should aim at more accurate risk assessment of obstetric
complications through studies with higher case numbers and standardisation of outpatient management under evidence-based criteria.

Am J Obstet Gynecol 2022; 227:296.e1-296.e18. [PMID: 35257664 DOI: 10.1016/j.ajog.2022.02.037] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Revised: 02/05/2022] [Accepted: 02/22/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND Preterm premature rupture of membranes complicates approximately 3% of pregnancies. Currently, in the absence of chorioamnionitis or placental abruption, expectant management, including antenatal steroids for lung maturation and prophylactic antibiotic treatment, is recommended. The benefits of individualized management have not been adequately explored. OBJECTIVE This study aimed to compare the impact of 2 different management strategies of preterm premature rupture of membranes in 2 tertiary obstetrical centers on latency of >7 days, latency to birth, chorioamnionitis, funisitis, and short-term adverse maternal and neonatal outcomes. STUDY DESIGN This was a multicenter retrospective study of women with singleton pregnancies with preterm premature rupture of membranes from 23 0/7 to 33 6/7 weeks of gestation between 2014 and 2018 and undelivered within 24 hours after hospital admission managed at Sunnybrook Health Sciences Center, Toronto, Canada (standard management group), and BCNatal (Hospital Clínic of Barcelona and Hospital Sant Joan de Déu Barcelona), Barcelona, Spain (individualized management group), following local protocols. The standard management group received similar management for all patients, which included a standard antibiotic regimen and routine maternal and fetal surveillance, whereas the individualized management group received personalized management on the basis of amniocentesis at hospital admission (if possible), to rule out microbial invasion of the amniotic cavity and targeted treatment. The exclusion criteria were cervical dilatation >2 cm, active labor, contraindications to expectant management (acute chorioamnionitis, placental abruption, or abnormal fetal tracing), and major fetal anomalies. The primary outcome was latency of >7 days, and the secondary outcomes included latency to birth, chorioamnionitis, and short-term adverse maternal and neonatal outcomes. Statistical comparisons between groups were conducted with propensity score weighting. RESULTS A total of 513 pregnancies with preterm premature rupture of membranes were included in this study: 324 patients received standard management, and 189 patients received individualized management, wherein amniocentesis was performed in 112 cases (59.3%). After propensity score weighting, patients receiving individualized management had a higher latency of >7 days (76.0% vs 41.6%; P<.001) and latency to birth (18.1±14.7 vs 9.7±9.7 days; P<.001). Although a higher rate of clinical chorioamnionitis was suspected in the individualized management group than the standard group (34.5% vs 22.0%; P<.01), there was no difference between the groups in terms of histologic chorioamnionitis (67.2% vs 73.4%; P=.16), funisitis (57.6% vs 58.1%; P=.92), or composite infectious maternal outcomes (9.1% vs 7.9%; P=.64). Prolonged latency in the individualized management group was associated with a significant reduction of preterm birth at <32 weeks of gestation (72.1% vs 90.5%; P<.001), neonatal intensive care unit admission (75.6% vs 83.0%; P=.046), and neonatal respiratory support at 28 days of life (16.1% vs 26.1%; P<.01) compared with that in the standard management group. Moreover, prolonged latency was not associated with neonatal severe morbidity at discharge (survival without severe morbidity, 80.4% vs 73.5%; P=.09). CONCLUSION Individualized management of preterm premature rupture of membranes may prolong pregnancy and reduce preterm birth at <32 weeks of gestation, the need for neonatal support, and neonatal intensive care unit admissions, without an increase in histologic chorioamnionitis, funisitis, neonatal infection-related morbidity, and short-term adverse maternal and neonatal outcomes.

Abstract
Background There is a lack of literature on short latency period (SLP) in twin pregnancies with preterm premature rupture of membranes (PPROM). Thus, the aim of this study was to identify the clinical factors and perinatal outcomes associated with SLP in twin pregnancies with PPROM and to establish a predictive model to identify SLP. Methods Twin pregnancies with PPROM between 24 0/7 and 33 6/7 weeks were included and a retrospective analysis was performed. Patients were divided into two groups based on the latency period after PPROM: Group 1 ≤24 h (defined as SLP) and Group 2 >24 h (defined as long latency period, LLP), the clinical factors and perinatal outcomes were compared between the two groups. Binary logistic regression and receiver operating characteristic curve analyses were used to identify the independent clinical factors associated with latency period after PPROM and assess the predictive accuracy for SLP. Results 98 and 92 pregnant women had short and long latency period, respectively. Prolonged latency significantly increased the occurrence of chorioamnionitis. Neonatal outcomes were not affected by latency duration after PPROM. Binary regression analysis revealed that higher gestational age (GA) at PPROM (P = 0.038), presence of uterine contractions (P < 0.001), Bishop score > 4 (P = 0.030), serum procalcitonin levels ≥0.05 ng/mL upon admission, and absence of use of tocolytic agents (P < 0.001) were significant independent predictors of a SLP. A predictive model developed using these predictors had an area under the curve (AUC) of 0.838, and the presence of uterine contractions alone had an AUC of = 0.711. Conclusion Uterine contraction was the most important prognosticator for a SLP. A latency period of >24 h was associated with chorioamnionitis, but adverse neonatal outcomes were not observed.

Abstract
In preterm premature rupture of membranes (PPROM), a decision between early delivery with prematurity complications and pregnancy prolongation bearing the risk of chorioamnionitis has to be made. To define disadvantages of delayed prolongation, latency duration of PPROM in expectantly managed pregnancies was investigated. We included those PPROMs > 48 h leading to preterm birth prior 37 weeks' gestation and retrospectively analyzed 84 preterm infants fulfilling these criteria. The association between latency duration/appearance of PPROM and respiratory outcome (primary outcomes) and neurological outcome (secondary outcomes) was investigated. The study showed that latency duration of PPROM is not associated with clinical or histological chorioamnionitis (p = 0.275; p = 0.332). As the numerous clinical parameters show multicollinearity between each other, we performed a multiple regression analysis to consider this fact. Respiratory distress syndrome is significantly associated with gestational age at PPROM (p < 0.001), and surfactant application is significantly associated with PPROM duration (p = 0.014). The other respiratory parameters including steroids and diuretics therapy, bronchopulmonary dysplasia, and the neurological parameters (intraventricular hemorrhage, Bayley II testing at a corrected age of 24 months) were not significantly associated with PPROM duration or gestational age at PPROM diagnosis.Conclusion: Latency duration of PPROM was not associated with adverse neonatal outcome in expectantly and carefully managed pregnancies, but respiratory distress syndrome was pronounced. The observed effect of pronounced respiratory distress syndrome can be treated with surfactant preparations and was not followed by increased rate of bronchopulmonary dysplasia. What is Known: • In case of preterm premature rupture of membranes, a decision between pregnancy prolongation with the risk of chorioamnionitis and early delivery with prematurity complications has to be made. • Chorioamnionitis is a dangerous situation for the pregnant woman and the fetus. • Impaired neurodevelopmental outcome is strongly correlated with pronounced prematurity due to the increased rate of serious complications. What is New: • Respiratory distress syndrome is significantly associated with gestational age at PPROM, and surfactant application is significantly associated with PPROM duration. • Latency duration of PPROM is not associated with adverse respiratory neonatal outcome (therapy with continuous positive airway pressure, therapy with diuretics and/or steroids, bronchopulmonary dysplasia) in expectantly and carefully managed pregnancies. • Intraventricular hemorrhage and Bayley II testing at a corrected age of 24 months are not associated with latency duration of PPROM when pregnancies are carefully observed.

Abstract
Objective To compare different antibiotic prophylaxis administered after preterm premature rupture of membranes to determine whether any were associated with differences in obstetric and/or neonatal outcomes and/or neurodevelopmental outcomes at 2 years of corrected age. Design Prospective, nationwide, population‐based EPIPAGE‐2 cohort study of preterm infants. Setting France, 2011. Sample We included 492 women with a singleton pregnancy and a diagnosis of preterm premature rupture of membranes at 24–31 weeks. Exclusion criteria were contraindication to expectant management or indication for antibiotic therapy other than preterm premature rupture of membranes. Antibiotic prophylaxis was categorised as amoxicillin (n = 345), macrolide (n = 30), third‐generation cephalosporin (n = 45) or any combinations covering Streptococcus agalactiae and >90% of Escherichia coli (n = 72), initiated within 24 hours after preterm premature rupture of membranes. Methods Population‐averaged robust Poisson models. Main Outcome Measures Survival at discharge without severe neonatal morbidity, 2‐year neurodevelopment. Results With amoxicillin, macrolide, third‐generation cephalosporin and combinations, 78.5%, 83.9%, 93.6% and 86.0% of neonates were discharged alive without severe morbidity. The administration of third‐generation cephalosporin or any E. coli‐targeting combinations was associated with improved survival without severe morbidity (adjusted risk ratio 1.25 [95% confidence interval 1.08–1.45] and 1.10 [95 % confidence interval 1.01–1.20], respectively) compared with amoxicillin. We evidenced no increase in neonatal sepsis related to third‐generation cephalosporin‐resistant pathogen. Conclusion In preterm premature rupture of membranes at 24–31 weeks, antibiotic prophylaxis based on third‐generation cephalosporin may be associated with improved survival without severe neonatal morbidity when compared with amoxicillin, with no evidence of increase in neonatal sepsis related to third‐generation cephalosporin‐resistant pathogen. Tweetable Abstract Antibiotic prophylaxis after PPROM at 24–31 weeks: 3rd‐generation cephalosporins associated with improved neonatal outcomes. Antibiotic prophylaxis after PPROM at 24–31 weeks: 3rd‐generation cephalosporins associated with improved neonatal outcomes.

Abstract
To describe the perinatal outcomes of twin pregnancies with preterm premature rupture of membranes (PPROM) before 34 weeks’ gestation and identify factors associated with discharge without severe or moderate-severe neonatal morbidity. This study was conducted as a retrospective analysis of twin pregnancies with PPROM occurring at 24 0/7 to 33 6/7 weeks’ gestation. Perinatal outcomes were assessed by gestational age (GA) at PPROM and compared between PPROM and non PPROM twins. Factors associated with discharge without severe or moderate-severe neonatal morbidity were identified using logistic regression analysis. Of the 180 pregnancies (360 foetuses), only 17 (9.4%) women remained pregnant 7 days after PPROM. There were 10 (2.8%) cases of prenatal or neonatal death; 303 (84.2%) and 177 (49.2%) neonates were discharged without severe or moderate-severe morbidity, respectively. As GA at PPROM increased, the adverse obstetric and neonatal outcomes decreased, especially after 32 weeks. There was no significant difference in general neonatal outcomes between PPROM and non PPROM twins. The GA at PPROM and latency period were both significantly associated with discharge without severe or moderate-severe neonatal morbidity. Pregnancy complications and 5-min Apgar score < 7 increased severe neonatal morbidity. As GA at PPROM increased, the risk of adverse perinatal outcomes decreased. GA at PPROM and latency period were significantly associated with discharge without severe or moderate-severe neonatal morbidity.

Abstract
INTRODUCTION Preterm prelabor rupture of membranes (PPROM) occurs in 3% of pregnancies and is the main cause (~30%) of premature delivery. Home care seems to be a safe alternative for the management of patients with PPROM, who have a longer latency than those with PPROM managed with conventional hospitalization. We aimed to identify the risk factors associated with a shortened latency before delivery in women with PPROM managed as outpatients. MATERIAL AND METHODS The design was a retrospective cohort study and the setting was a Monocentric Tertiary centre (Lille University Hospital, France) from 2009 to 2018. All consecutive patients in home care after PPROM at 24-36 weeks were included. For the main outcome measure we calculated the latency ratio for each patient as the ratio of the real latency period to the expected latency period, expressed as a percentage. The risk factors influencing this latency ratio were evaluated. RESULTS A total of 234 patients were managed at home after PPROM. Mean latency was 35.5 ± 20.7 days, corresponding to an 80% latency ratio. In 196 (83.8%) patients the length of home care was more than 7 days. A lower latency ratio was significantly associated with oligohydramnios (p < 0.001), gestational age at PPROM (p = 0.006), leukocyte count at PPROM more than 12 × 109 /L (p = 0.025), and C-reactive protein concentration more than 5 mg/L at 7 days after PPROM (p = 0.046). Cervical length was not associated with a lower latency ratio. CONCLUSIONS Women with PPROM managed with home care are stable. The main risk factor associated with a reduced latency is oligohydramnios. Outpatients with oligohydramnios should be informed of the probability of a shortened latency period.

Abstract
BACKGROUND Culture-proven sepsis is the gold standard in early-onset neonatal sepsis diagnosis. Infants born ≤29 weeks gestation after preterm rupture of membranes in the years 2009-2015 were included in a retrospective cohort study performed at a level III fetal-maternal unit. The study aimed to compare culture-proven sepsis, clinical sepsis and positive laboratory biomarkers ≤72 h as predictors of mortality before discharge and the combined outcome of mortality or severe short-term morbidity (severe cerebral morbidity, bronchopulmonary dysplasia and retinopathy). RESULTS Of the 354 patients included, culture-proven sepsis, clinical sepsis and laboratory biomarkers were positive in 2.3%, 8.5% and 9.6%, respectively. The mortality rate was 37.5% for patients with culture-proven sepsis (3/8), 33.3% for patients with clinical sepsis (10/30) and 8.8% for patients with positive laboratory biomarkers (3/34), respectively. Mortality or severe morbidity occurred in 75.0% of patients with culture-proven sepsis (6/8), 80.0% of patients with clinical sepsis (24/30) and 44.1% of patients with positive laboratory biomarkers (15/34), respectively. CONCLUSION In preterm infants after preterm rupture of membranes, clinical sepsis was almost four times more common and at least equally valuable in predicting mortality and mortality or severe morbidity compared to culture-proven sepsis.

Abstract
Prelabour rupture of membranes (PROM) exposes both foetuses and mothers to the risk of infection. Induction of labour has been proposed to reduce this risk, but its neonatal and maternal risks and benefits must be balanced against those of expectant management (EM). Recent randomized studies of preterm PROM show that EM until 37 weeks of gestation is associated with lower overall neonatal morbidity. In term PROM, active management is associated with a shorter birth interval but not with lower rates of neonatal infection. Similar maternal and neonatal outcomes are reported regardless of whether induction uses oxytocin, PGE2, or oral misoprostol.

Lorthe E, Kayem G. Tocolysis in the management of preterm prelabor rupture of membranes at 22-33 weeks of gestation: study protocol for a multicenter, double-blind, randomized controlled trial comparing nifedipine with placebo (TOCOPROM). BMC Pregnancy Childbirth 2021; 21:614. [PMID: 34496799 PMCID: PMC8425321 DOI: 10.1186/s12884-021-04047-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 08/12/2021] [Indexed: 11/17/2022] Open
Abstract
Background Preterm prelabor rupture of membranes (PPROM) before 34 weeks of gestation complicates 1% of pregnancies and accounts for one-third of preterm births. International guidelines recommend expectant management, along with antenatal steroids before 34 weeks and antibiotics. Up-to-date evidence about the risks and benefits of administering tocolysis after PPROM, however, is lacking. In theory, reducing uterine contractility could delay delivery and reduce the risks of prematurity and its adverse short- and long-term consequences, but it might also prolong fetal exposure to inflammation, infection, and acute obstetric complications, potentially associated with neonatal death or long-term sequelae. The primary objective of this study is to assess whether short-term (48 h) tocolysis reduces perinatal mortality/morbidity in PPROM at 22 to 33 completed weeks of gestation. Methods A randomized, double-blind, placebo-controlled, superiority trial will be performed in 29 French maternity units. Women with PPROM between 220/7 and 336/7 weeks of gestation, a singleton pregnancy, and no condition contraindicating expectant management will be randomized to receive a 48-hour oral treatment by either nifedipine or placebo (1:1 ratio). The primary outcome will be the occurrence of perinatal mortality/morbidity, a composite outcome including fetal death, neonatal death, or severe neonatal morbidity before discharge. If we assume an alpha-risk of 0.05 and beta-risk of 0.20 (i.e., a statistical power of 80%), 702 women (351 per arm) are required to show a reduction of the primary endpoint from 35% (placebo group) to 25% (nifedipine group). We plan to increase the required number of subjects by 20%, to replace any patients who leave the study early. The total number of subjects required is thus 850. Data will be analyzed by the intention-to-treat principle. Discussion This trial will inform practices and policies worldwide. Optimized prenatal management to improve the prognosis of infants born preterm could benefit about 50,000 women in the European Union and 40,000 in the United States each year.

Factors associated with a latency < 7 days after preterm premature rupture of membranes between 22 and 32 weeks of gestation in singleton pregnancies. J Gynecol Obstet Hum Reprod 2021; 50:102194. [PMID: 34224901 DOI: 10.1016/j.jogoh.2021.102194] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 06/28/2021] [Accepted: 06/30/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To identify factors at admission associated with a latency < 7 days after Preterm premature rupture of membranes (PPROM) between 22 and 32 weeks of gestation in singleton pregnancies. MATERIAL AND METHODS A retrospective comparative study of all women with singleton pregnancies admitted for PPROM to an academic tertiary center during the 5-year period of 2015-2019. Women who gave birth < 7 days and ≥ 7 day after PPROM were compared. We determined risk at admission associated with a latency < 7 days after PPROM by logistic regression and identified high-risk subgroups by classification and regression tree (CART) analysis. RESULTS Among 174 eligible births, 76 (44%) women gave birth < 7 days after PPROM and 98 (56%) later. The two groups had similar maternal baseline and obstetric characteristics. In multivariate analysis, the following variables reported at admission were independently associated with a latency < 7 days: painful uterine contractions (aOR 3.9, 95%CI 1.1-7.4), cervical length < 20 mm (aOR 2.4, 95%CI 1.2-4.8), and C reactive protein ≥ 10 mg/L (aOR 2.4, 95% CI 1.3-4.8). Women with painful uterine contractions and cervical length at admission < 20 mm were at highest risk of latency < 7 days (rate: 91%). Conversely, the women at lowest risk were those without uterine contractions, with a cervical length ≥ 20 mm, and C-reactive protein < 10 mg/L at admission (rate: 22%). CONCLUSION Our results may be helpful in determining criteria at admission for selecting women eligible for outpatient care after an initial hospitalization.

Abstract
OBJECTIVE To study the clinical features of very preterm infants with prelabor rupture of membranes (PROM) and predictive factors for early-onset sepsis (EOS) and death. METHODS A retrospective analysis was performed for the clinical data of the very preterm infants with PROM (with a gestational age of < 32 weeks) who were admitted to the neonatal intensive care unit from January 2018 to May 2020. According to the time from membrane rupture to delivery, the infants were divided into four groups: < 18 hours (n=107), 18 hours to < 3 days (n=111), 3 days to < 14 days (n=144), and ≥ 14 days (n=37). According to the presence or absence of EOS, the infants were divided into EOS (n=42) and non-EOS groups (n=357). According to the survival state, the infants were divided into a survival group (n=359) and a death group (n=40). Clinical features were analyzed for very preterm infants with different times of PROM. A multivariate logistic regression analysis was used to investigate the predictive factors for EOS and death in very preterm infants with PROM. RESULTS There was no significant difference in the incidence rates of major neonatal complications and mortality rate among the very preterm infants with different times of PROM (P > 0.05). Birth weight < 1 000 g (OR=4.353, P=0.042), grade Ⅲ amniotic fluid contamination (OR=4.132, P=0.032), and grade Ⅲ-Ⅳ respiratory distress syndrome (RDS) (OR=2.528, P=0.021) were predictive factors for EOS in very preterm infants with PROM. Lower birth weights (< 1 000 g or 1 000-1 499 g; OR=11.267 and 3.456 respectively; P=0.004 and 0.050 respectively), grade Ⅲ-Ⅳ RDS (OR=5.572, P < 0.001), and neonatal sepsis (OR=2.631, P=0.012) were predictive factors for death in very preterm infants with PROM. CONCLUSIONS Prolonged PROM does not increase the incidence of neonatal complications and mortality in very preterm infants. Adverse outcomes of very preterm infants with PROM are mainly associated with lower birth weights, lung immaturity, and systemic infection.

Abstract
BACKGROUND Preterm prelabor rupture of membranes (PPROM) is a major cause of morbidity and mortality for both the mother and the newborn. The vaginal germ profile in PPROM is poorly known, particularly regarding the risk of early-onset neonatal infection (EONI). OBJECTIVE To determine microbiological risk factors for EONI in case of PPROM before 34 weeks of gestation (WG). STUDY DESIGN A retrospective single-center cohort of patients with PPROM before 34 W G from 2008 to 2016. Vaginal swabs were obtained at admission and at delivery as per usual care and were analyzed by Gram stain and culture for vaginal dysbiosisi.e lactobacilli depletion and/or presence of potential pathogens. RESULTS Among 268 cases of PPROM, 39 neonates had EONI 14.55 %; (95 %CI 0.11 - 0.19) Overall, vaginal samples culture was positive in 16.67 % (95 %CI 11.95 %-22.32 %) at the time of rupture and 24.76 % (95 %CI 19.02 %-31.23 %) at delivery, with no significant differences between EONI and no-EONI groups (p = 0.797 and 0.486, respectively), including for Group B Streptococci (GBS) and Escherichia coli. EONI was significantly associated with dysbiosis at the time of rupture (23.94 % versus 10.35 % in the absence of dysbiosis, p = 0.009) and at delivery (19.70 % versus 3.90 % if no dysbiosis, p < 0.001). Clinical intra-uterine infection was present in 78.5 % (n = 31) of the EONI group versus 37.2 % (n = 85) in the non-EONI group (p < 0.001) and chorioamnionitis and/or funisitis were found in 97.3 % and 91.9 %, respectively in the EONI group, versus 56.11 % and 53.96 %, respectively, in the non-EONI group (p < 0.001). CONCLUSION Dysbiosis following rupture and at delivery, but not the presence of pathogens in the VS culture, was associated with the risk of EONI in case of PPROM.

Detection of small for gestational age in preterm prelabor rupture of membranes by Hadlock versus the Fetal Medicine Foundation growth charts. Obstet Gynecol Sci 2021; 64:248-256. [PMID: 33486918 PMCID: PMC8138067 DOI: 10.5468/ogs.20267] [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: 09/06/2020] [Accepted: 11/25/2020] [Indexed: 11/08/2022] Open
Abstract
Objective The primary outcome was to compare the diagnostic accuracy of neonatal small for gestational age (SGA) by the Hadlock and Fetal Medicine Foundation (FMF) charts in our cohort, followed by the ability to predict composite severe neonatal outcomes (SNO) in pregnancies with preterm prelabor rupture of membranes (PPROM). Methods This study was a secondary analysis of a prospective cohort of pregnancies with PPROM from 2015 to 2018, from 23 to 36 completed weeks of gestation. Sensitivity, specificity, and positive and negative predictive values for the primary and secondary outcomes of the Hadlock and FMF fetal charts were calculated. The discriminatory ability of each chart was compared using the area under the receiver’s operating curves of clinical characteristics. Results Of the 106 women who met the inclusion criteria, 48 (45%) were screened positive using the FMF fetal growth chart and 22 (21%) were screened positive using the Hadlock chart. SGA was diagnosed in 12 infants (11%). Both fetal growth charts had comparable diagnostic accuracies and were statistically significant predictors of SGA (Hadlock: area under the receiver operating characteristic curves [AUC], 0.76, risk ratio [RR], 7.6, 95% confidence interval [CI], 2.5–23; and FMF: AUC, 0.76 RR, 13.3 95%CI 1.8–99.3). Both growth standards were poor predictors of SNO. Conclusion The Hadlock and FMF fetal growth charts have a similar accuracy to predict SGA in pregnancies complicated by PPROM. The FMF fetal growth chart may result in a 2-fold increase in positive screens, potentially increasing fetal surveillance.

Branch pulmonary artery Doppler parameters predict early survival-non-survival in premature rupture of membranes. J Perinatol 2020; 40:1821-1827. [PMID: 32978527 DOI: 10.1038/s41372-020-00817-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 08/03/2020] [Accepted: 09/10/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND Preterm premature rupture of membrane (pPROM) leads to high neonatal mortality due in part to severe lung hypoplasia (LH). In other causes of severe LH, fetal echo-based parameters of smaller branch pulmonary arteries (PA), shorter acceleration to ejection time ratio (AT/ET), increased peak early diastolic reverse flow (PEDRF), and higher pulsatility index (PI) are predictive of worse neonatal outcome. We sought to determine whether these parameters correlated with worse clinical outcome in pPROM. METHODS Twenty-five pregnancies complicated by pPROM were prospectively recruited. Fetal echocardiography was used to evaluate branch PA diameters and Doppler parameters. Clinical records were reviewed. Fetal echo findings were compared between early survivors and non-survivors. RESULTS Of 25 pPROM cases, 5 had early neonatal demise (≤3 days) due to respiratory insufficiency. While gestational age at pPROM, fetal echo, and at birth did not differ, amniotic fluid index (AFI) was significantly lower in early non-survivors compared to survivors (p = 0.05). No difference was observed in PA diameter, PEDRF, or PI; however, branch PA AT/ET was significantly shorter in non-survivors (right PA median 0.12 (0.11-0.16) vs. survivors 0.17 (0.14-0.21), p = 0.046 and left PA 0.12 (0.09-0.13) vs. survivors 0.16 (0.11-0.21), p = 0.042). CONCLUSIONS We found a significantly lower AFI and shorter fetal bilateral branch PA AT/ET to be associated with early neonatal demise following pPROM.

Abstract
OBJECTIVE To gain an overview of the current management of patients with preterm prelabor rupture of membranes (PPROM) in Swiss maternity hospitals. STUDY DESIGN We conducted a survey among all maternity hospitals in Switzerland from January to December 2018, irrespective of their annual birth rate and level of complexity. The survey consisted of an 11-item questionnaire, which was developed to retrieve information relevant to different areas of PPROM management. RESULTS Of 64 questionnaires distributed by email, 36 (56.3%) centers responded to the survey. Up to 12 different antibiotic regimens were reported. Among these, 91.7% included a beta-lactam, with amoxicillin as the preferred agent (55.6%). Combined antibiotic schemes were used in 30.6% of hospitals. All centers considered the use of corticosteroids for fetal lung maturity if PPROM occurred before 34 weeks, although 36.1% would consider their use until 37 weeks' gestation in the presence of an increased risk of neonatal respiratory distress syndrome. Maternity hospitals who accept deliveries at any gestational age usually used magnesium sulfate as fetal neuroprotection when delivering babies <32 weeks, with the exception of two hospitals where it was either not used or only indicated if maternal preeclampsia was present. Concerning the time to delivery, 58.3% centers tended to wait until 37 weeks' gestation, while the others considered that it was not necessary to go beyond 34 weeks. CONCLUSION Our survey shows that the current management of PPROM in Switzerland appears to be mostly in line with international recommendations. However, some heterogeneity exists, thus reflecting a lack of international consensus across guidelines, together with the absence of national Swiss guidelines, and this needs to be addressed to ensure high quality care for all patients and neonates.

Abstract
Preterm birth occurs in approximately 10% of all births in the United States and is a major contributor to perinatal morbidity and mortality (). Prelabor rupture of membranes (PROM) that occurs preterm complicates approximately 2-3% of all pregnancies in the United States, representing a significant proportion of preterm births, whereas term PROM occurs in approximately 8% of pregnancies (). The optimal approach to assessment and treatment of women with term and preterm PROM remains challenging. Management decisions depend on gestational age and evaluation of the relative risks of delivery versus the risks (eg, infection, abruptio placentae, and umbilical cord accident) of expectant management when pregnancy is allowed to progress to a later gestational age. The purpose of this document is to review the current understanding of this condition and to provide management guidelines that have been validated by appropriately conducted outcome-based research when available. Additional guidelines on the basis of consensus and expert opinion also are presented. This Practice Bulletin is updated to include information about diagnosis of PROM, expectant management of PROM at term, and timing of delivery for patients with preterm PROM between 34 0/7 weeks of gestation and 36 6/7 weeks of gestation.

Abstract
Antimicrobial prophylaxis is widely recommended for pregnant women who have preterm premature rupture of the membranes. Erythromycin prophylaxis was used during an initial period (control) and then changed to intravenous amoxicillin for 48 h, followed by 5 days of oral amoxicillin along with a single dose of azithromycin (case). Healthcare records were reviewed retrospectively. The primary outcome was latency (between membrane rupture and delivery) and the secondary outcomes were mode of delivery, maternal high dependency unit (HDU) admission, and several laboratory parameters. There were 78 women in the case group (amoxicillin and azithromycin) and controls were selected on a 1:1 ratio. There was no statistically significant difference between cases and controls with respect to group B Streptococcus or E.coli carriage, previous preterm birth, assissted fertility and parity. No babies had a positive blood culture with Group B Streptococcus. There was a longer latency to delivery for those prescribed amoxicillin and azithromycin (median = 5.5 days), compared with controls on erythromycin (median = 2 days, p < .001). There was no difference in the mode of delivery or maternal HDU admission. Given the potential sequelae of preterm birth, this warrants further prospective investigation in a randomised control trial.IMPACT STATEMENTWhat is already known on this subject? Antimicrobial prophylaxis is recommended for women who have preterm premature rupture of the membranes (PPROM). It has been shown to increase latency of delivery. However there are different regimens recommended in North America (amoxicillin and a macrolide) and the United Kingdom (macrolide monotherapy).What do the results of this study add? This study has shown that in our population, women who were prescribed the PPROM regimen of amoxicillin with azithromycin had a longer median latency from time of rupture of membranes to delivery, than women in a historical control group who were prescribed erythromycin monotherapy.What are the implications of these findings for clinical practice and/or further research? This retrospective study has shown that there may be a difference in latency between different antimicrobial prophylaxis regimens for PPROM. A randomised control trial, with sufficient patient numbers, is needed to determine the best regimen for prophylaxis, and would allow harmonisation of international guidelines.

Abstract
AIM Preterm premature rupture of membranes (PPROM) is common in preterm births. Fetal inflammatory response syndrome (FIRS) is present in nearly 50% of PPROM cases. We created a risk score to predict FIRS using maternal factors after PPROM. METHODS We conducted a retrospective study of singleton pregnancies complicated by PPROM that resulted in delivery at 23-35 weeks of gestation. Antepartum maternal factors and umbilical cord blood interleukin-6 (IL-6) data were analyzed. FIRS was defined as IL-6 > 11 pg/mL. RESULTS Umbilical cord blood IL-6 and maternal blood data within 24 h before parturition were available for 158 cases; 66 were diagnosed with FIRS (41.8%; median IL-6, 57.55 pg/mL). We created a risk score (FIRS score) comprising expected delivery weeks (≤30 weeks), maternal C-reactive protein (≥1.2 mg/dL), maternal white blood cell count (≥13 000/μL), corticosteroid use (none) and PROM latency period (≥3 days) from the multivariate logistic regression model predicting FIRS. Receiver operating characteristic curve analysis of the score produced the following results: area under the curve, 0.82; 95% CI, 0.76-0.89; cut-off value, 7.5; sensitivity, 89%; specificity, 63%; positive predictive value, 63% and negative predictive value, 89%. The probability of FIRS according to the categories of the FIRS score was 11% for those with a score of 0-7, 50% for a score of 8-15, and 88% for a score of 16-22. CONCLUSION The devised maternal risk score could predict FIRS and be helpful to decide the delivery timing for the cases of PPROM.

Abstract
OBJECTIVE To assess whether chorioamnionitis is associated with cerebral palsy (CP) or death at 2 years' corrected age in infants born before 32 weeks of gestation after spontaneous birth. STUDY DESIGN EPIPAGE-2 is a national, prospective, population-based cohort study of children born preterm in France in 2011; recruitment periods varied by gestational age. This analysis includes infants born alive after preterm labor or preterm premature rupture of membranes from 240/7 to 316/7 weeks of gestation. We compared the outcomes of CP, death at 2 years' corrected age, and "CP or death at age 2" according to the presence of either clinical chorioamnionitis or histologic chorioamnionitis. All percentages were weighted by the duration of the recruitment period. RESULTS Among 2252 infants born alive spontaneously before 32 weeks of gestation, 116 (5.2%) were exposed to clinical chorioamnionitis. Among 1470 with placental examination data available, 639 (43.5%) had histologic chorioamnionitis. In total, 346 infants died before 2 years and 1586 (83.2% of the survivors) were evaluated for CP at age 2 years. CP rates were 11.1% with and 5.0% without clinical chorioamnionitis (P = .03) and 6.1% with and 5.3% without histologic chorioamnionitis (P = .49). After adjustment for confounding factors, CP risk rose with clinical chorioamnionitis (aOR 2.13, 95% CI 1.12-4.05) but not histologic chorioamnionitis (aOR 1.21, 95% 0.75-1.93). Neither form was associated with the composite outcome "CP or death at age 2." CONCLUSIONS Among infants very preterm born spontaneously, the risk of CP at a corrected age of 2 years was associated with exposure to clinical chorioamnionitis but not histologic chorioamnionitis.

Abstract
Objective: To evaluate the association between latency and neonatal morbidity for pregnancies with expectant management of PPROM ≥34 w.Materials and Methods: A retrospective cohort of singletons with PPROM from 2011 to 2016. Exposure was defined as latency (period from diagnosis of PPROM to delivery) and was analyzed as a count variable (i.e. number of days) and binary variable (≥7 days and <7 days; ≥21 days and <21 days). Primary outcome was composite neonatal morbidity defined as need for respiratory support, culture positive neonatal sepsis, and/or neonatal antibiotics >72 h. Fisher's exact test, chi-square test, Mann-Whitney U and binary logistic regression tests were performed with p<.05 considered significant.Results: Of 813 pregnancies, 104 met inclusion criteria: 73 (70.2%) pregnancies with PPROM diagnosed at <34 weeks and 31 (29.8%) pregnancies with PPROM diagnosed ≥34 weeks. A total of 58 (55.8%) pregnancies had a latency of ≥7 days and 46 (44.2%) had a latency <7 days. There was no difference in composite neonatal morbidity for latency ≥7 d versus <7 d (aOR 0.92; 95% CI 0.30-2.82) or latency as a count variable (aOR 0.70; 95% CI 0.23-2.13). However, a latency ≥21 d was associated with increased composite neonatal morbidity (aOR 10.24, 95% CI 1.42-73.99).Conclusion: In pregnancies with PPROM expectantly managed ≥34 w, a latency of ≥7 d is not associated with significant differences in neonatal morbidity. However, different latency thresholds may be more clinically relevant for late preterm pregnancies. The increase in composite neonatal morbidity associated with a latency >21 days should be an area of future investigation and may suggest there is a population of pregnancies with PPROM which may not benefit from expectant management past 34 weeks.

Abstract
Chorioamnionitis (CA) is considered a key risk factor for very preterm birth and for developing early onset sepsis (EOS) in preterm infants, but recent data suggest that CA might be protective against late onset sepsis (LOS). We performed a systematic review and meta-analysis of studies exploring the association between CA and sepsis. A comprehensive literature search was performed in PubMed/MEDLINE and EMBASE, from their inception to December 1, 2018. A random-effects model was used to calculate odds ratios (OR) and 95% confidence intervals (CI). Sources of heterogeneity were analyzed by subgroup and meta-regression analyses. The following categories of sepsis were analyzed: EOS, LOS, unspecified onset sepsis (UOS), culture-proven, and clinical sepsis. CA was subdivided into clinical and histological chorioamnionitis. Funisitis was also analyzed. We found 3,768 potentially relevant studies, of which 107 met the inclusion criteria (387,321 infants; 44,414 cases of CA). Meta-analysis showed an association between any CA and any EOS (OR 4.29, CI 3.63-5.06), any LOS (OR 1.29, CI 1.11-1.54), and any UOS (OR 1.59, CI 1.11-1.54). Subgroup analysis showed that CA was associated with culture-proven EOS (OR 4.69, CI 3.91-5.56), clinical EOS (OR 3.58, CI 1.90-6.76), and culture-proven LOS (OR 1.31, CI 1.12-1.53), but not with clinical LOS (OR 1.52, CI 0.78-2.96). The presence of funisitis did not increase the risk of either EOS or LOS when compared with CA without funisitis. CA-exposed infants had lower gestational age (-1.11 weeks, CI -1.37 to -0.84) than the infants not exposed to CA. Meta-regression analysis showed that the lower gestational age of the CA group correlated with the association between CA and LOS but not with the association between CA and EOS. In conclusion, our data suggest that the positive association between chorioamnionitis and LOS may be modulated by the effect of chorioamnionitis on gestational age.

Abstract
OBJECTIVE To evaluate the use of the intracervical balloon compared with locally applied prostaglandins for cervical ripening for induction in patients with preterm premature rupture of membranes. METHODS Monocentric, retrospective (from 2002 to 2017) observational cohort study of singleton pregnancies complicated by preterm premature rupture of membranes and induced between 34 and 37 weeks. The primary outcome measure was balloon catheter efficiency evaluated by Cesarean section rate. Secondary outcomes were : interval from induction to delivery, labor duration, oxytocin use, intrauterine infection rate, maternal complications (i.e., postpartum hemorrhage and endometritis), and neonatal complications. RESULTS 60 patients had cervical ripening with prostaglandins alone and 58 had balloon catheter. Demographic characteristics were similar between the groups, except for induction term and neonatal weight. There was not a significant difference in occurrence of Cesarean section rate (p = 0.14). Nor were there significant differences in time from induction to birth (p = 0.32) or in intrauterine infection rate (p = 0.95). Labor duration was shorter (p = 0.006) and total oxytocin dose lower (p = 0.005) in patients induced by prostaglandins alone. Concerning neonatal outcomes, there were more transfers to intensive care (p = 0.008) and more respiratory distress (p = 0.005) among newborns induced by prostaglandins. CONCLUSION Compared with locally applied prostaglandins, balloon catheter induction is not associated with an increase of Cesarean section rate in patients with preterm premature rupture of membranes.

Abstract
OBJECTIVE To study the effect of different antibiotic use strategies on infection in neonates with premature rupture of membranes and the high-risk factors for neonatal infection. METHODS A retrospective analysis was performed for the clinical data of 223 neonates with premature rupture of membranes. According to the antibiotic use strategies, they were classified into two groups: study group (n=95) and control group (n=128). The neonates in the study group were given antibiotics based on risk assessment and infection screening, and those in the control group were given antibiotics based on risk assessment alone after admission. General status and prognosis were compared between the two groups. According to the presence or absence of infection, the neonates were classified into two groups: infection group (n=32) and non-infection group (n=191). The clinical data were compared between the two groups. A logistic regression model was used to investigate the high-risk factors for infection in neonates with premature rupture of membranes. RESULTS Compared with the control group, the study group had a significantly longer time of premature rupture of membranes, a significantly higher rate of cesarean section, and a significantly lower antibiotic use rate at admission and a significantly lower total antibiotic use rate (P<0.05). The study group also had a significantly higher incidence rate of infection and a significantly lower incidence rate of sepsis (P<0.05). There were no significant differences in the incidence rates of other complications between the two groups (P>0.05). Compared with the non-infection group, the infection group had a significantly lower gestational age, a significantly longer time of premature rupture of membranes, a significantly higher rate of cesarean section, and significantly higher levels of C-reactive protein (CRP) and procalcitonin on admission and during reexamination (P<0.05), with fever as the most common symptom. The logistic regression analysis showed that preterm birth and cesarean section were high-risk factors for infection in neonates with premature rupture of membranes (P<0.05). CONCLUSIONS Strict adherence to the indications for antibiotic use in neonates with premature rupture of membranes does not increase the incidence rate of complications. Neonates with premature rupture of membranes, especially preterm infants and infants delivered by cesarean section, should be closely observed for the change in disease conditions, and infection indices including CRP should be reexamined in case of fever and antibiotics should be used to prevent serious infection.

Abstract
Objective Imperfect culture sensitivity and increase of early onset neonatal sepsis (EONS) risk in preterm neonates raise concern that culture-based intrapartum antibiotic prophylaxis (IAP) may be insufficient after preterm premature rupture of membranes (PPROM). Our objective was to compare rates of EONS after empiric versus culture-based IAP in PPROM. Study Design This retrospective cohort study included women with a singleton gestation and PPROM between 23 and 33 weeks. Outcomes after culture-based IAP were compared with empiric IAP. The primary outcome was EONS. Secondary outcomes included group B streptococcus (GBS) bacteremia, bacteremia, and neonatal GBS infection. Bivariable and multivariable logistic analyses were performed. Results Of the 270 women who met inclusion criteria, 136 (50%) had culture-based IAP of whom 36 (26.5%) were GBS positive. There was no significant difference in bacteremia (2.2 vs. 4.5%, p = 0.30), GBS infection (0.8 vs. 0.7%, p = 1.00), or EONS (11.8 vs. 12.7%, p = 0.82) in infants of women with culture-based IAP compared with empiric IAP. Multivariable analysis confirmed a lack of advantage to empiric versus culture-based IAP in EONS risk (adjusted odds ratio [aOR] = 0.82, 95% confidence interval [CI]: 0.44-1.93). Conclusion In pregnancies complicated by PPROM, infants of women who received culture-based IAP had no significant difference in EONS or GBS infection compared with infants of women with empiric IAP.

Abstract
AIM Given the scarcity of relevant reports, this study aimed to elucidate whether pregnancy can be prolonged by maintaining the amniotic fluid volume with continuous transabdominal amnioinfusion (TA) for patients with mid-trimester preterm premature rupture of membranes (PPROM) and oligoamnios. METHODS We retrospectively examined patients who were managed during hospitalization at our department after developing PPROM between week 22 day 0 and week 25 day 6 of gestation and subsequent oligoamnios (amniotic fluid index [AFI] <5 cm) within 7 days after PPROM onset. Cases between 2006 and 2011 comprised the conventional management group (n = 14); cases administered continuous TA between 2012 and 2017 comprised the continuous TA group (n = 14). The primary outcome was the number of days between PPROM and delivery. The secondary outcomes were the proportion of normal amniotic fluid volume (AFI ≥ 5 cm) maintained between PPROM and delivery and the perinatal prognosis for the mother and infant. RESULTS The continuous TA group had significantly more days between PPROM and delivery and a significantly higher proportion of days that a normal amniotic fluid volume was maintained during that period, regardless of antimicrobial agents administered. Although no significant differences in the perinatal prognosis of disease were found between groups, there was a decreasing trend of composite perinatal mortality and morbidity, and the incidence rates were reduced by half. CONCLUSION Continuous TA for PPROM with oligoamnios may allow significant prolongation of the gestation period while maintaining the amniotic fluid volume and may lead to improved perinatal prognosis.

Abstract
OBJECTIVE To evaluate risk factors associated with neonatal morbidity and mortality in pregnant women with preterm prelabor rupture of membranes (PPROM) after cervical cerclage. METHODS A retrospective cohort study of singleton pregnancies with cervical insufficiency was conducted at a tertiary referral center in Taiwan from May 1, 2000 to July 31, 2017. Patients with PPROM after cerclage and delivered between 20 0/7 days and 36 6/7 days were recruited. Logistic and linear regression analyses were performed to evaluate various risk factors. RESULTS Overall, 109 women were included. Mothers with a higher white blood cell count, a higher C-reactive protein (CRP) level, a lower amniotic fluid index, and chorioamnionitis were significantly associated with neonatal morbidity. Neonatal mortality was related to oligohydramnios (adjusted odds ratio [aOR] 2.98, 95% confidence interval [CI] 1.11-8.01) and chorioamnionitis (aOR 3.17, 95% CI 1.03-9.69). An elevated CRP level was associated with a shorter PPROM to delivery latency (adjusted B -16.64, 95% CI -29.88 to -3.41), but cerclage retention more than 12 hours after PPROM was associated with a prolonged latency (adjusted B 17.21, 95% CI 3.25-31.18). CONCLUSION Oligohydramnios and chorioamnionitis are associated with neonatal mortality.

Abstract
OBJECTIVE To assess the impact of bed rest on maternal and neonatal outcomes in pregnancies complicated by preterm premature rupture of the membranes (PPROM), enabling proper sample size calculation for a powered randomized controlled trial (RCT). STUDY DESIGN We conducted a pilot unblinded randomized controlled trial with a 1:1 allocation ratio (complete bed rest vs activity restriction groups) on singleton pregnancies complicated by PPROM at 24 + 0-33 + 6 weeks. Maternal and neonatal data were compared between groups with an intent-to-treat analysis. The primary outcomes were the latency time to delivery and the incidence of chorioamnionitis. The trial was conducted in a tertiary center of the Portuguese national healthcare system. Patients received standard antibiotic prophylaxis. Delivery was planned for the 34th week of gestation, except in cases of spontaneous labor or another complication. RESULTS Thirty-two cases were randomized and analyzed, 14 in the complete bed rest group and 18 in the activity restriction group. The median gestational age at PPROM was 30 vs 29 weeks (p = 0.82). In the complete bed rest group, the incidence of chorioamnionitis was nonsignificantly lower (14% vs 28%, p = 0.43). Median latency time was 11.5 days (95% CI, 2-20) in the complete bed rest group and 7.5 days (95% CI, 3-11) in the activity restriction group, lacking statistical significance on univariate (p = 0.6) and survival analyses (log-rank test, p = 0.75). No difference was found between groups regarding indication or type of delivery and maternal or neonatal morbidity. The median gestational age at delivery was 32 weeks for both groups (p = 0.94). A sample size of 2052 participants was calculated for a powered RCT, considering latency as the primary outcome. CONCLUSION In this pilot trial, bed rest did not increase latency to delivery and did not improve maternal or neonatal morbidity in the setting of PPROM at 24 + 0-33 + 6 weeks. A sample size calculation is now available for a powered RCT.

Abstract
Objectives: We investigated the incidence and outcome of clinical and histological chorioamnionitis (CA) and the associated risk factors in an emerging provincial perinatal center in 2014-2015.Study design: Based on the suspected and proven clinical infection in the third trimester of pregnancy, placenta and accessories from singleton deliveries were routinely examined histologically. The incidence of CA and associated fetal and neonatal outcome were compared by the total deliveries.Results: Of the 14,166 deliveries in 12 months, infection and inflammation were found in 373 out of 2372 (15.7%) placentas subjected to histological examination and diagnosed as CA (2.6%). These cases were divided into four groups as histological CA only (HCA, n = 335), clinical and histological CA (HCC, n = 20), clinical CA only (CCA, n = 18) and non-CA control (CON, n = 1999). Thus, an incidence of histological CA was 2.5% (355/14 166) in this birth population. Compared to CON, HCA group was more likely to have premature rupture of membrane, antenatal antibiotic use, gestational age <34 weeks, fetal distress, positive bacterial culture from vaginal secretions, and early-onset sepsis in newborns (all p ≤ .01), which were associated with perinatal risk factors of CA. In the very preterm subgroups, more stillbirths and death at delivery and neonatal intensive care unit admissions (p < .001) were found in the CA group.Conclusions: The results suggested that histological CA was associated with early-onset sepsis and combined perinatal comorbidities which are of more diagnostic importance than clinical only CA. The placental histological examination should be routinely performed in very preterm births to better assess perinatal and neonatal outcome.

Eur J Obstet Gynecol Reprod Biol 2018; 233:30-37.

Abstract
OBJECTIVES Preterm premature rupture of fetal membranes (PPROM) exposes the fetus to preterm birth, and optimal timing for delivery is controversial. The aim of this study was to compare intentional early delivery ("active management") with expectant management in very preterm birth (28-32 weeks). STUDY DESIGN We conducted a prospective randomized controlled trial with intent-to-treat analysis, at 19 tertiary-care hospitals in France and 1 in Geneva, Switzerland. Inclusion criteria were women age ≥18 years, PPROM at 280/7 to 316/7 weeks' gestation, singleton pregnancy. Exclusion criteria were maternal/fetal indications for immediate delivery. All participants received prophylactic antibiotics (amoxicillin + gentamicin) and two doses of corticosteroids. Women in expectant management delivered at 34 weeks, sooner if medically indicated. Women in active management delivered 24 h after the second steroid dose. The primary outcome measure was a composite of neonatal death/severe adverse events: periventricular leukomalacia, intraventricular hemorrhage, sepsis, oxygen requirement at 36 weeks, and necrotizing enterocolitis. The secondary outcome was clinical chorioamnionitis. RESULTS The trial was stopped prematurely, due to recruitment difficulties. Of 360 women assessed, 139 (40% of calculated sample size) were randomized: 70 to expectant management, 69 to active management. Mean gestational age at PPROM was similar in both groups (30 ± 1.3 vs. 30.2 ± 1.2 weeks, respectively). There were 35 cases of medical/suspected complications requiring delivery in expectant management vs. 4 in active management. Mean latency between PPROM and delivery was 11.7 ± 9.8 vs. 2.8 ± 0.6 days, respectively; P < 0.0001 (median 8.4 (1.8-44.2) vs. 2.7 (1.9-4.3)). There were more caesarean deliveries in active than expectant management (80% vs. 60%, respectively; P < 0.01). There were 2 chorioamnionitis cases, both in expectant management. One baby died in expectant management; 2 in active management (one with heart defect). There was no significant difference in sepsis rates. The combined neonatal death/severe adverse events measure was 12.9% for expectant management and 13.0% for active management (OR 0.98; 95% CI: 0.33-2.93, P = 0.97). CONCLUSION For PPROM at 28-32 weeks, and with antenatal antibiotic and steroid therapy, there were no observed differences in neonatal health when comparing expectant management to early delivery. As expected, expectant management resulted in higher gestational age and birth weight. However, our study was underpowered to draw firm and reliable conclusions.

Abstract
OBJECTIVE To identify the ideal gestational age at delivery for preterm premature rupture of membranes and modalities of birth. METHOD To identify studies, research was conducted using Pub-Med, Embase and Cochrane databases. RESULTS Prolonged latency duration after pPROM does not worsen neonatal prognosis (NP3). Therefore, it is recommended not to deliver before 34 weeks of gestation for patient with uncomplicated preterm rupture of membranes (pPROM) (Grade C). After 34 weeks of gestation, expectant management for pPROM is not associated with neonatal sepsis (NP1) but is associated to intra-uterine infection (NP2). Early delivery is associated with higher risk of respiratory distress syndrome (NP2), higher risk of cesarean section (NP2) and longer duration of NICU hospitalization (NP2). Before 37 weeks of gestation, expectant management is recommended for uncomplicated pPROM (Grade A), even if vaginal group B streptococcus is positive, as long as antibiotics are used at the time of membranes rupture (Professional consensus). Elective cesarean section is reserved for usual obstetrical indications. Oxytocin and prostaglandins are reasonable options for inducing labor (Professional consensus). Data are too scarce to establish recommendation regarding intra-cervical balloons in case of pPROM (Professional consensus). CONCLUSION Expectant management is recommended for uncomplicated pPROM before 37 weeks of gestation.

Abstract
OBJECTIVES To synthetize the available evidence regarding the incidence and risk factors of preterm premature rupture of membranes (PPROM). To describe the evolution of pregnancy, neonatal outcomes and the prognosis of infants born in a context of PPROM, according to the existence of an associated intrauterine infection and to the latency duration. METHOD Consultation of the Medline database, from 1980 to February 2018. RESULTS PPROM before 37 and before 34 weeks' gestation occur in 2-3% and <1% of pregnancies, respectively (LE2). Although many risk factors are identified, few are modifiable, and the vast majority of patients have no risk factors (LE2). Consequently, individual prediction of the risk of PPROM and primary prevention measures have not been shown to be effective and are not recommended in clinical practice (Grade B). Most women give birth within the week following PPROM (LE2). The main complications of PPROM are prematurity, intrauterine infection and obstetric and maternal complications (LE2). Latency duration and the frequency of complications decrease with increasing gestational age at PPROM (LE2). Neonatal prognosis is largely conditioned by gestational age at birth, with no apparent over-risk of poor outcomes linked to PPROM compared to other causes of preterm birth (LE2). In contrast, intrauterine infection is associated with an increased risk of in utero fetal death (LE3), necrotizing enterocolitis (LE1) and early-onset sepsis (LE2). The association of intrauterine infection with neurological morbidity remains controversial. Prolongation of latency, from gestational age at PPROM, is beneficial for the child (LE2). CONCLUSION PPROM is a major cause of prematurity and short- and long-term mortality and morbidity. Antenatal care is an important issue for obstetric and pediatric teams, aiming to reduce complications and adverse consequences for both mother and child.

Abstract
Objective: Preterm premature rupture of membranes (PPROM) is a risk factor for chorioamnionitis (CA) and injury to the fetal brain. However, prolongation of gestation prevents morbidity and decreases complications of prematurity. The current investigation is to define risk factors for the adverse neurological outcome from the influence of PPROM of at least 7 days.Methods: A case-control study included three groups of preterm infants born at the University Hospitals Bonn and Essen, Germany. The first group consisted of infants with PPROM of at least 7 days and no chorioamnionitis (CA) (PPROM group), the second included preterm infants with CA (CA group), and the third group consisted of infants without PPROM and CA (control group). The outcome was assessed using Bayley Scales of Infant Development at a corrected age of 24 months. Each group consisted of 20 corresponding infants with an identical birth weight and gestational age at birth.Results: There was no significant difference between the mental development index (MDI) and psychomotor development index (PDI) scores (mean ± SD): the MDI score was 101 ± 14 in the PPROM group, 98 ± 12 in the CA group and 96 ± 17 in the control group; the PDI score 96 ± 10, 89 ± 16, and 90 ± 17, respectively. Multiple regression analysis revealed no significant influence of PPROM and CA on neurological outcome.Conclusions: PPROM of at least 7 days has no influence on neurodevelopmental outcome at a corrected age of 24 months when birth is initiated in the case of beginning CA.

Abstract
BACKGROUND Most clinical guidelines state that with early preterm premature rupture of membranes, obstetric and pediatric teams must share a realistic and individualized appraisal of neonatal outcomes with parents and consider their wishes for all decisions. However, we currently lack reliable and relevant data, according to gestational age at rupture of membranes, to adequately counsel parents during pregnancy and to reflect on our policies of care at these extreme gestational ages. OBJECTIVE We sought to describe both perinatal and 2-year outcomes of preterm infants born after preterm premature rupture of membranes at 22-25 weeks' gestation. STUDY DESIGN EPIPAGE-2 is a French national prospective population-based cohort of preterm infants born in 546 maternity units in 2011. Inclusion criteria in this analysis were women diagnosed with preterm premature rupture of membranes at 22-25 weeks' gestation and singleton or twin gestations with fetus(es) alive at rupture of membranes. Latency duration, antenatal management, and outcomes (survival at discharge, survival at discharge without severe morbidity, and survival at 2 years' corrected age without cerebral palsy) were described and compared by gestational age at preterm premature rupture of membranes. RESULTS Among the 1435 women with a diagnosis of preterm premature rupture of membranes, 379 were at 22-25 weeks' gestation, with 427 fetuses (331 singletons and 96 twins). Median gestational age at preterm premature rupture of membranes and at birth were 24 (interquartile range 23-25) and 25 (24-27) weeks, respectively. For each gestational age at preterm premature rupture of membranes, nearly half of the fetuses were born within the week after the rupture of membranes. Among the 427 fetuses, 51.7% were survivors at discharge (14.1%, 39.5%, 66.8%, and 75.8% with preterm premature rupture of membranes at 22, 23, 24, and 25 weeks, respectively), 38.8% were survivors at discharge without severe morbidity, and 46.4% were survivors at 2 years without cerebral palsy, with wide variations by gestational age at preterm premature rupture of membranes. Survival at 2 years without cerebral palsy was low with preterm premature rupture of membranes at 22 and 23 weeks but reached approximately 60% and 70% with preterm premature rupture of membranes at 24 and 25 weeks. CONCLUSION Preterm premature rupture of membranes at 22-25 weeks is associated with high incidence of mortality and morbidity, with wide variations by gestational age at preterm premature rupture of membranes. However, a nonnegligible proportion of children survive without severe morbidity both at discharge and at 2 years' corrected age.

Abstract
BACKGROUND Preterm premature rupture of membrane (PPROM) can lead to serious consequences such as intrauterine infection, prolapse of the umbilical cord, and neonatal respiratory distress syndrome. Genital infection is a very important risk which closely related with PPROM. The preliminary study only made qualitative research on genital infection, but there was no deep and clear judgment about the effects of pathogenic bacteria. This study was to analyze the association of infections with PPROM in pregnant women in Shaanxi, China, and to establish Bayesian stepwise discriminant analysis to predict the incidence of PPROM. METHODS In training group, the 112 pregnant women with PPROM were enrolled in the case subgroup, and 108 normal pregnant women in the control subgroup using an unmatched case-control method. The sociodemographic characteristics of these participants were collected by face-to-face interviews. Vaginal excretions from each participant were sampled at 28-36+6 weeks of pregnancy using a sterile swab. DNA corresponding to Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), Candida albicans, group B streptococci (GBS), herpes simplex virus-1 (HSV-1), and HSV-2 were detected in each participant by real-time polymerase chain reaction. A model of Bayesian discriminant analysis was established and then verified by a multicenter validation group that included 500 participants in the case subgroup and 500 participants in the control subgroup from five different hospitals in the Shaanxi province, respectively. RESULTS The sociological characteristics were not significantly different between the case and control subgroups in both training and validation groups (all P > 0.05). In training group, the infection rates of UU (11.6% vs. 3.7%), CT (17.0% vs. 5.6%), and GBS (22.3% vs. 6.5%) showed statistically different between the case and control subgroups (all P < 0.05), log-transformed quantification of UU, CT, GBS, and HSV-2 showed statistically different between the case and control subgroups (P < 0.05). All etiological agents were introduced into the Bayesian stepwise discriminant model showed that UU, CT, and GBS infections were the main contributors to PPROM, with coefficients of 0.441, 3.347, and 4.126, respectively. The accuracy rates of the Bayesian stepwise discriminant analysis between the case and control subgroup were 84.1% and 86.8% in the training and validation groups, respectively. CONCLUSIONS This study established a Bayesian stepwise discriminant model to predict the incidence of PPROM. The UU, CT, and GBS infections were discriminant factors for PPROM according to a Bayesian stepwise discriminant analysis. This model could provide a new method for the early predicting of PPROM in pregnant women.

Abstract
OBJECTIVE Premature rupture of the membranes (PROM) remains a leading cause of neonatal morbidity. The objectives of the present study were to analyze the outcomes of pregnancies complicated by PROM between 22 and 27+6 weeks of gestation (WG) and to study antepartum risk factors that might predict neonatal death. PATIENTS AND METHODS One hundred and seven pregnancies were analyzed over a 3-year period in a tertiary maternity hospital. The collected maternal and neonatal data were used to model and predict the outcome of PROM. RESULTS Prevalence of PROM (for live births) was 1.08%, and the overall survival rate was 59.8%. From preselected candidate variables, gestational age (GA) at PROM (p = .0002), a positive vaginal culture for pathogenic bacteria (p = .01), primiparity (p = .02), and the quantity of amniotic fluid (p = .03) were included in a multivariable logistic regression analysis. The corresponding adjusted odds ratios [95% confidence interval] were, respectively, 0.91 [0.87-0.96], 11.08 [1.65-74.42], 0.55 [0.33-0.91], and 0.97 [0.95-0.99]. These parameters were used to build a predictive score for neonatal death. CONCLUSIONS The survival rate after PROM at 22-27+6 weeks of gestation was 59.8%. Our predictive model (built using multivariable logistic regression) may be of value for obstetricians and neonatologists counseling couples after PROM.

BMJ Paediatr Open 2017; 1:e000216. [PMID: 29637178 PMCID: PMC5862203 DOI: 10.1136/bmjpo-2017-000216] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2017] [Revised: 11/30/2017] [Accepted: 12/02/2017] [Indexed: 01/18/2023] Open
Abstract
OBJECTIVE To determine the hospital outcomes of liveborn infants at 23-31 weeks following prelabour preterm rupture of membranes (PPROM). METHOD A regional retrospective cohort study of 4454 infants of 23-31 weeks' gestation admitted to a tertiary neonatal network between 2007 and 2011. Primary outcome was the composite chronic lung disease (CLD) or mortality at discharge. RESULTS 225 (5%) neonates had a history of PPROM occurring prior to 24+0 weeks (Early-PPROM), 829 (19%) had a history of PPROM at or after 24+0 weeks' gestation (Late-PPROM) and 3400 (76%) had no history of PPROM (No-PPROM). In comparison to No-PPROM, Early-PPROM group had higher CLD/mortality in infants born at 23-27 weeks (OR 1.95; 95% CI 1.34 to 2.85) and 28-31 weeks (OR 4.98; 95% CI 2.99 to 8.28). Within Early-PPROM group, the latency of PPROM >14 days had lower CLD/mortality in comparison to latency ≤14 days (57.6% vs 77%, OR 0.40; 95% CI 0.21 to 0.76). Late-PPROM group had significantly lower CLD/mortality in comparison to No-PPROM group at 23-27 weeks (OR 0.50; 95% CI 0.37 to 0.69) and 28-31 weeks (OR 0.50; 95% CI 0.36 to 0.71). Within Late-PPROM group, latency >14 days was associated with an increased CLD/mortality in 28-31 weeks (14.1% vs 5.4%, OR 2.88; 95% CI 1.31 to 6.38). CONCLUSIONS Early-PPROM prior to 24 weeks' gestation had high incidence of CLD/mortality even after correcting for gestational age. Late-PPROM at or after 24 weeks had lower CLD/mortality compared with No-PPROM. Latency >14 days in Late-PPROM group at 28-31 week group increased the odds of CLD/mortality.
