P0231PREGNANCY AND DELIVERY OUTCOMES IN PATIENTS WITH COMPLEMENT GENE VARIANT MEDIATED THROMBOTIC MICROANGIOPATHY

Abstract Background and Aims In pregnancy and the postpartum period, complement gene variant mediated thrombotic microangiopathy (P-cTMA) can be life threatening for the mother and the child. We describe pregnancy and delivery outcomes of pregnancies a) before cTMA manifestation, b) complicated by P-cTMA, and c) after first manifestation of cTMA in such women. Method This study provides an update of patients enrolled in the Vienna TMA Cohort (VTC) as of January 2020. Demographic and clinical data were retrieved from the electronic and paper-based health care records of our institution and from the Austrian Mother-Child Health Passport. Pregnancy outcomes include live births (full term, moderate to late preterm, very preterm, extremely preterm) or deaths (miscarriage, foetal death, stillbirth, neonatal death). Among delivery outcome we ascertained spontaneous vaginal delivery; Caesarean section, gestational age, birth weight and birth weight categories, birth height, head circumference, Apgar scores, admission to a neonatal intensive care unit, and the presence of malformations. Results We recorded 58 pregnancies (41 live births/21 women, including one set of twins; 4 abortions and 1 stillbirth in 3 women without live births; 1 ongoing pregnancy; successful pregnancies: 40/57=70%) of 25 women (mean age [years] at first pregnancy 28.2±7.4, at cTMA manifestation 33.2±16.5). Currently 6 women have a kidney transplant and 4 have died (each death not related to pregnancy). Detailed pregnancy outcomes are shown in Figure 1. Table 1 indicates delivery outcomes of 41 live births. 6/8 neonates of pregnancies complicated by cTMA were female. Caesarean sections (female: 11/19, 58%; male: 9/24, 38%; p=0.11), preterm deliveries (female: 7/19, 37%; male: 5/24, 21%; p=0.09), and low birth weight (female: 6/19, 32%; male: 3/24, 13%; p=0.02) were more frequent among 43 pooled live births and stillbirths with known sex. Conclusion Overall, pregnancy and delivery outcomes were poor in pregnancies complicated by cTMA as compared to pregnancies before or after cTMA manifestation. The rate of Caesarean section, preterm delivery, and low birth weight was somewhat higher among female as compared to male neonates and stillbirths. Furthermore, neonatal female gender should be explored as risk factor for cTMA manifestation.

Objective The objective of this study is to assess the effect of the lockdown measures during the coronavirus disease 2019 (COVID-19) pandemic on pregnancy outcomes of women who were not affected by severe acute respiratory syndrome coronavirus 2 infection. Study Design We used data from the perinatal health program and neonatal databases to conduct a cohort analysis of pregnancy outcomes during the COVID-19 lockdown in the Calgary region, Canada. Rates of preterm birth were compared between the lockdown period (March 16 to June 15, 2020) and the corresponding pre-COVID period of 2015 to 2019. We also compared maternal and neonatal characteristics of preterm infants admitted to neonatal intensive care units (NICUs) in Calgary between the two periods. Findings A total of 4,357 and 24,160 live births occurred in the lockdown and corresponding pre-COVID period, respectively. There were 366 (84.0 per 1,000 live births) and 2,240 (92.7 per 1,000 live births) preterm births in the lockdown and corresponding pre-COVID period, respectively (p = 0.07). Rates of very preterm and very-low-birth-weight births were lower in the lockdown period compared with the corresponding pre-COVID period (11.0 vs. 15.6 and 9.0 vs. 14.4 per 1,000 live births, p = 0.02 and p = 0.005, respectively). There was no difference in spontaneous stillbirth between the two periods (3.7 vs. 4.1 per 1,000 live birth, p = 0.71). During the lockdown period, the likelihood of multiple births was lower (risk ratio [RR] 0.73, 95% confidence interval [CI]: 0.60–0.88), while gestational hypertension and clinical chorioamnionitis increased (RR 1.24, 95%CI: 1.10–1.40; RR 1.33, 95%CI 1.10–1.61, respectively). Conclusion Observed rates of very preterm and very-low-birth-weight births decreased during the COVID-19 lockdown. Pregnant women who delivered during the lockdown period were diagnosed with gestational hypertension and chorioamnionitis more frequently than mothers in the corresponding pre-COVID period.

Abstract Objectives To examine pregnancy outcomes among births to women with idiopathic inflammatory myopathy (IIM) in relation to time of IIM diagnosis using population-based data. Methods This study used Swedish nationwide registers to identify all singleton births that occurred between 1973 and 2016 among women diagnosed with IIM between 1998 and 2016 and among women unexposed to IIM. We classified births according to the IIM status of the mother at time of delivery: post-IIM (n = 68), 1–3 years pre-IIM (n = 23), >3 years pre-IIM (n = 710) and unexposed to IIM (n = 4101). Multivariate regression models were used to estimate relative risks of adverse pregnancy outcomes in post-IIM births and pre-IIM births separately, in comparison with their non-IIM comparators. Results We found that post-IIM births had increased risks of caesarean section [adjusted relative risk (aRR) = 1.98; 95% CI: 1.08, 3.64], preterm birth (aRR = 3.35; 95% CI: 1.28, 8.73) and low birth weight (aRR = 5.69; 95% CI: 1.84, 17.55) compared with non-IIM comparators. We also noticed higher frequencies of caesarean section and instrumental delivery in 1–3 years pre-IIM births than in the non-IIM comparators. Conclusion Women who gave birth after IIM diagnosis had higher risks of caesarean section, preterm birth and low birth weight. These results further underline the importance of special care and close monitoring of women with IIM. Higher frequencies of caesarean section and instrumental delivery in pre-IIM births highlight the need for future research on the influence of subclinical features of IIM on pregnancy outcomes.

Background:Chronic inflammatory diseases (CID) in women of reproductive age are increasingly being treated with tumour necrosis factor inhibitors (TNFi), in line with recent guidelines.1 However, data on TNFi-exposed pregnancy outcomes are still limited. Certolizumab pegol (CZP), a PEGylated, Fc-free TNFi, has no/minimal placental transfer from mother to infant during the third trimester.2Objectives:To assess pregnancy outcomes from the UCB Pharmacovigilance safety database from over 1,300 prospectively reported pregnancies with maternal CZP exposure.Methods:Details of CZP-exposed pregnancies from the UCB Pharmacovigilance safety database were reviewed up to November 1, 2020. Analysis was limited to prospectively reported cases with known pregnancy outcomes to avoid potential reporting bias. Confounders (specific CID, non-biologic medications and maternal infection) were evaluated using a multivariate stepwise regression model; results from the confounders analysis are reported as odds ratios (OR) with 95% confidence intervals (CI). Patients with missing information about presence or absence of confounders were excluded from the model.Results:1,392 prospective pregnancies (1,425 fetuses) with maternal CZP exposure and known outcomes were reported (Figure 1). Mean (SD) maternal age was 31.9 (5.1) years. Of these, 1,021/1,392 (73.3%) pregnancies had at least first-trimester CZP exposure and 547/1,392 (39.3%) were exposed during all trimesters. Overall, there were 1,259/1,425 (88.4%) live births, 150/1,425 (10.5%) abortions (miscarriages and terminations), 11/1,425 (0.8%) stillbirths, and 5/1,425 (0.4%) ectopic pregnancies. Congenital malformations were reported in 35/1,425 fetuses (2.5%) and in 30/1,259 live-born infants (2.4%); 26 (2.1%) congenital malformations were major according to the Metropolitan Atlanta Congenital Defects Program criteria. There was no pattern of specific congenital malformations. Preterm births occurred in 124/1,259 (9.8%) live births, and 101/1,259 (8.0%) of infants had low birth weight (<2.5 kg). In the confounders analysis, reported corticosteroid use was independently associated with increased odds of preterm birth (OR [95% CI]: 2.1 [1.3–3.4]; p<0.005) and low birth weight (OR [95% CI]: 1.7 [1.0–2.9]; p<0.05), but decreased odds of abortion (OR [95% CI]: 0.5 [0.3–0.9]; p<0.05). Reported NSAID use was associated with increased odds of abortion (OR [95% CI]: 2.2 [1.2–4.0]; p<0.05), as was methotrexate/leflunomide use (OR [95% CI]: 3.2 [1.7–6.2]; p<0.0005). Maternal infections were associated with increased odds of preterm birth (OR [95% CI]: 1.9 (1.1–3.5; p<0.05). Finally, there was an association between a diagnosis of Crohn’s disease and odds of abortion (OR [95% CI]: 2.5 [1.5–4.1]; p=0.0005), and between rheumatoid arthritis and low birth weight (OR [95% CI]: 1.9 [1.1–3.3]; p<0.05).Conclusion:This prospective analysis, including more than 1,000 pregnancies with CZP exposure in at least the first trimester, represents one of the largest cohorts of pregnancies with known outcomes in patients with CID. Our data confirm the impact of specific CID, concomitant drugs or comorbidities on pregnancy outcomes. In particular, additional use of corticosteroids was highlighted as a risk factor for preterm birth and low birth weight in our cohort of CZP-treated patients. No increase in adverse pregnancy outcomes or specific congenital malformations was observed in CZP-exposed pregnancies, compared to the general population,3,4 which offers further reassurance for women of childbearing age considering CZP treatment.References:[1]Sammaritano LR.

The COVID 19 pandemic represents a major stress factor for non-infected pregnant women. Although maternal stress during pregnancy increases the risk of preterm birth and intrauterine growth restriction, an increasing number of studies yielded no negative effects of COVID 19 lockdowns on pregnancy outcome. The present study focused on pregnancy outcome during the first COVID 19 lockdown phase in Austria. In particular, it was hypothesized that the national lockdown had no negative effects on birth weight, low birth weight rate and preterm birth rate. In a retrospective medical record-based single center study, the outcome of 669 singleton live births in Vienna Austria during the lockdown phase between March and July 2020 was compared with the pregnancy outcome of 277 live births at the same hospital during the pre-lockdown months of January and February 2020 and, in addition, with the outcome of 28,807 live births between 2005 and 2019. The rate of very low gestational age was significantly lower during the lockdown phase than during the pre-lockdown phase. The rate of low gestational age, however, was slightly higher during the lockdown phase. Mean birth weight was significantly higher during the lockdown phase; the rates of low birth weight, very low birth weight and extremely low birth weight were significantly lower during the lockdown phase. In contrast, maternal gestational weight gain was significantly higher during the lockdown phase. The stressful lockdown phase in Austria seems to have no negative affect on gestational length and newborn weight among non-infected mothers.

Abstract Background The Covid-19 pandemic response is influencing maternal and neonatal health care services especially in developing countries. However, the indirect effects of Covid-19 on pregnancy outcomes remain unknown. The aim of the present study was to compare pregnancy outcomes before and after the beginning of the Covid-19 pandemic in Iran. Methods We performed a retrospective analysis of the medical records of 2,503 pregnant women with singleton pregnancies, admitted to the maternity department of a women’s hospital in Tehran, Iran, during the pre-Covid-19 pandemic (February 19 to April 19, 2019) and the intra-Covid- 19 pandemic (February 19 to April 19, 2020) period. Results We included 2,503 women admitted to the hospital; 1,287 (51.4 %) were admitted before the Covid-19 lockdown and 1,216 (48.6 %) during the Covid-19 lockdown. There were no significant differences in stillbirth rates (p = 0.584) or pregnancy complications (including preeclampsia, pregnancy-induced hypertension and gestational diabetes) (p = 0.115) between pregnant women in the pre- and intra-pandemic periods. However, decreases in preterm births (p = 0.001), and low birth weight (p = 0.005) were observed in the pandemic period compared to the pre-pandemic period. No significant difference in the mode of delivery, and no maternal deaths were observed during the two time periods. Conclusions In our study we observed a decrease in preterm births and low birth weight, no change in stillbirths, and a rise in the admission rates of mothers to the ICU during the initial Covid-19 lockdown period compared to pre-Covid-19 lockdown period. Further research will be needed to devise plan for immediate post-pandemic care and future health care crises.

Order Of Magnitude ◽

Almost All

About one tenth of all infant deaths occur in babies weighing less than 500 g at birth, almost all of whom die very shortly thereafter. In 1983, when the United States reported 3,638,933 live births, 4,368 of them were less than 500 g; that year there were 26,507 neonatal deaths. This means that slightly more than 0.1% of all live births contributed to 17% of neonatal mortality. Given this order of magnitude, any change in the numbers relating to these tiny babies can have a disproportionate influence on reported infant mortality and on interstate comparisons. Two questions promptly arise. How accurate and meaningful are the data regarding babies born weighing less than 500 g? What can be done to decrease the deaths in this category? Wilson et al1 call attention to how the number of very low birth weight infants reported by a state may be affected by the state's definition of a live birth.

Overview Objective: Analysis of perinatal mortality in the Slovak Republic during the years 2007–2018. Methods: Analysis of prospectively collected selected perinatal data in the years 2007–2018. Results: In the year 2007, there were 63 obstetrics units, 51,146 deliveries and that of live births 51,650 in the Slovak Republic. The number of obstetrics units decreased to 51 in the years 2018, the total number of deliveries increased to 57,085 and that of live births increased to 57,773. The total fertility rate in the years 2007–2018 increased from 1.27 to 1.54. The preterm deliveries rate increased from 7.3% in the year 2007 to 8.5% in the year 2010 and decreased to 7% in the year 2018. The perinatal mortality rate decreased from 6.2 in the year 2007 to 4.4 in the year 2017, increased again in the years 2018 to 5.0 and according to the criteria of WHO (World Health Organization) to 6.6 per 1,000 still- and live-births. During the years 2007–2018 at perinatal mortality stillbirth participate with 65%, low birth weight with 63% and severe congenital anomalies with 19%. Transport in utero to perinatological centers in the years 2007–2018 has decreased from 57 to 56% for infants 1,000–1,499 g and from 75 to 73% for infants below 1,000 g. Conclusion: In the year 2017, perinatology in the Slovak Republic reached the best result in the perinatal mortality rate – 4.4‰ (0.44%), but has increased to over 5‰ next year. To further reduce perinatal mortality in the Slovak Republic, it is necessary to improve the prenatal diagnosis of severe congenital abnormalities, transport in utero of very low birth weight fetuses, centralization of high-risk pregnancies, obstetric personnel and material-technical equipment of obstetricians and neonatal intensive care units.

Adverse Pregnancy

Background and Aim: Advanced maternal age pregnancy could be referred to as pregnancy after 35 years or older. The prevalence of postponing pregnancies is increasing day by day worldwide. However, limited evidence was found on advanced maternal age pregnancy association with fetal adverse outcomes. The present study aimed to evaluate the frequency of advanced maternal age selected fetal adverse pregnancy outcomes. Place and Duration: Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera for duration of six months from November 2020 to April 2021. Materials and Methods: This single-centered retrospective study was conducted on 220 postpartum women in the study group (≥35 years) and 170 control group postpartum women (20-34 years) who delivered at Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera after 28 gestational weeks. Individuals who met the inclusion criteria were enrolled and sampled based on randomized control sampling technique for both control and study groups. Data extraction checklist and pretested questionnaire were used for data collection from the maternal charts. Adverse pregnancy outcome and advanced maternal age was correlated adjusted relative risks and strength with a 95% confidence interval. SPSS version 20 was used for data analysis and considered p-value >0.05 as a statistical standard. Results: The adverse neonatal outcomes include low birth weight, preterm birth, and stillbirth with a prevalence 38 (17.4%), 46 (20.8%), and 31 (14.2%) respectively in the study group. In the control group, the incidence of low birth weight, preterm birth, and stillbirth was 21 (12.6%), 15 (14.6%) and 6 (3.5%) respectively. The stillbirth (ARR=3.16 95% CI (1.29–6.03) and preterm deliveries (ARR=2.71 95% CI (1.79–3.86) risk had significantly higher prevalence compared to control group advanced age pregnancy. Insignificance association was found between low birth weight and advanced maternal age. Conclusion: Stillbirth and preterm birth was the adverse fetal outcome significantly related with advanced maternal age pregnancy. There was no significant association between low birth weight and advanced maternal age. Keywords: Maternal age, Fetal Adverse Pregnancy Outcomes
