Abstract
OBJECTIVE Women with sickle cell disease (SCD) have adverse maternal and infant outcomes. Our aim was to determine whether the outcomes of SCD mothers and their infants differed from African or Caribbean women not affected by SCD and whether there were differences between SCD individuals with the haemoglobin SS (HbSS) or haemoglobin SC (HbSC) genotypes. Furthermore, we wished to determine if any differences related to deprivation. DESIGN A matched cohort study. SETTING Tertiary perinatal centre in London PATIENTS: 4964 African or Caribbean women without SCD and 148 with SCD. MAIN OUTCOME MEASURES Mode of delivery, maternal exchange transfusion, birthweight, neonatal unit admission, neonatal death and deprivation indices RESULTS: SCD women were more likely to be delivered by caesarean section (p<0.001) and had babies of lower birthweight (p<0.001). Their infants were no more likely to be admitted to neonatal intensive care unit or suffer a neonatal death. There were no significant differences between the SCD women and those without SCD in their deprivation index or deprivation decile. The women with the HbSS genotype compared to those with the HbSC genotype were more anaemic (p<0.02), required more exchange transfusions (p<0.001) and were more likely to be delivered by caesarean section (p=0.008). The infant outcomes did not differ significantly between the genotypes. CONCLUSIONS Although, the SCD women, particularly those with the HbSS genotype, had greater morbidity, infant morbidity, and mortality was similar in mothers with the HbSS or HbSC genotypes and those without SCD.

Abstract
BACKGROUND Sickle cell disease (SCD) comprises a heterogeneous group of inherited hemolytic disorders that increases the risk of maternal and perinatal complications due to chronic systemic inflammatory response, endothelial damage and vaso-occlusion. The contribution of genotypes to the severity of outcomes during pregnancy is not completely established. METHODS A retrospective study of medical charts was performed to compare maternal and perinatal outcomes in Hb SS, Hb SC disease and sickle-beta thalassemia (Hb Sβ) pregnancies followed at a high-risk antenatal care unit over a 6-year period. A descriptive analysis of morphological findings was performed of the placenta when pathology reports were available. RESULTS Sixty-two SCD pregnant women [25 Hb SS (40 %), 29 Hb SC (47 %) and 8 Hb Sβ (13 %)] were included. Overall, SCD was associated with maternal complications (77 %), preterm birth (30 %), cesarean section (80 %) and a need of blood transfusion. In general there were no statistically significant differences between genotypes. The only significant difference was the hemoglobin level at first antenatal care visit which was lower for the homozygous genotype (7.7 g/dL) compared to Hb SC and Hb Sβ (9.7 g/dL and 8.4 g/dL, respectively; p-value = 0.01). Ten of 15 evaluated placentas showed abnormal morphological findings CONCLUSION: SCD, regardless of the underlying genotype, is associated with increased adverse maternal and perinatal outcomes and placental abnormalities associated with maternal vascular malperfusion.

Abstract
OBJECTIVE To evaluate the association between sickle cell disease (SCD) and severe maternal morbidity (SMM) in a contemporary cohort of deliveries by non-Hispanic Black people. METHODS We retrospectively examined SMM by using electronic health record data on deliveries by non-Hispanic Black patients between 2011 and 2020 at a single tertiary, public institution. Sickle cell disease was identified during the delivery admission by using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes. The primary outcome, SMM at delivery hospitalization, was ascertained using ICD-9-CM and ICD-10-CM codes and excluded sickle cell crisis as an indicator of SMM. We also constructed a secondary measure of SMM that excluded deliveries in which blood transfusion was the only indication of SMM. Poisson regression models were used to estimate risk ratios (RRs) and 95% CIs for the associations between SCD and SMM (overall and for individual indicators). Multivariable models adjusted for age, parity, insurance type, chronic conditions (chronic hypertension, diabetes mellitus, obesity), and multiple gestation. RESULTS Among 17,493 deliveries by non-Hispanic Black patients during the study period, 132 (0.8%) had a diagnosis of SCD. Of those patients, 87 (65.9%, 95% CI 57.2-73.9) with SCD and 2,035 (11.7%), 95% CI 11.2-12.2) without SCD had SMM. Sickle cell disease was associated with increased risk of SMM (87 vs 2,035, adjusted risk ratio [aRR] 5.4, 95% CI 4.6-6.3) and nontransfusion SMM (51 vs 1,057, aRR 6.0, 95% CI 4.6-8.0). Effect estimates were highest for cardiac arrest (3 vs 14, RR 28.2, 95% CI 3.8-209.3), air and thrombotic embolism (14 vs 72, RR 25.6, 95% CI 12.0-54.6), and puerperal cerebrovascular disorders (10 vs 53, RR 24.8, 95% CI 10.2-60.5). CONCLUSION Sickle cell disease was associated with a more than fivefold increased risk of SMM during the delivery hospitalization. Our data suggest cardiovascular morbidity as the driving major risk. The identification and monitoring of cardiovascular pathology in patients with SCD before and during pregnancy may reduce SMM.

Abstract
Pregnancy in women with sickle cell disease (SCD) is a life-threatening condition. In both high- and low-income countries, there is an 11-fold increased risk of maternal death and a 4-fold increased risk of perinatal death. We highlight the epidemiology of SCD-specific and obstetric complications commonly seen during pregnancy in SCD and propose definitions for acute pain and acute chest syndrome (ACS) episodes during pregnancy. We conducted a systematic review of the recent obstetric and hematology literature using full research articles published within the last 5 years that reported outcomes in pregnant women with SCD. The prevalence of acute pain episodes during pregnancy ranged between 4% and 75%. The prevalence of ACS episodes during pregnancy ranged between 4% and 13%. The estimated prevalence of pulmonary thromboembolism in women with SCD during pregnancy is approximately 0.5 to 1%. ACS is the most common cause of death and is often preceded by acute pain episodes. The most crucial time to develop these complications in pregnancy is during the third trimester and postpartum period. In a pooled analysis from studies in low- and middle-income settings, maternal death in women with SCD is approximately 2393 and 4300 deaths per 100 000 live births with and without multidisciplinary care, respectively. In comparison, in the US and northern Europe, the general maternal mortality rate is approximately 23.8 and 8 deaths per 100 000 live births, respectively. A multidisciplinary SCD obstetrics care approach reduces maternal and perinatal morbidity and mortality in low- and middle-income countries.

Abstract
INTRODUCTION Pregnancy in women with sickle cell disease (SCD) has been identified as high risk owing to increased incidence of materno-fetal complications across various studies and reports. These complications include consequences related to the underlying hemoglobinopathy; chronic anemia/associated inflammation, and pregnancy related including the risk for thromboembolism, bleeding and maternal mortality. Outcomes of neonates born to women with SCD has been suboptimal over the years with recent improvement due to strict monitoring, preventive and therapeutic measures. Much is yet to be unraveled regarding the optimal management of women with SCD during pregnancy, identifying target hemoglobin, delivery mode or timing among others. AREAS COVERED This review includes a summary of available data of the maternal and fetal outcomes; in addition to current recommendations for monitoring and management of women with SCD during pregnancy. EXPERT OPINION To have a successful pregnancy, women should be closely monitored, and interventions provided as needed to guarantee adequate management of anemia, as well as prevention, diagnosis and management of disease. They should also be educated regarding their reproductive health, emphasizing that pregnancy is possible, and achieving optimal results depends on providing adequate care in a health care facility with expertise in high-risk pregnancies and SCD.

Abstract
We aimed to identify risk factors for adverse outcomes in pregnancies of women with sickle cell disease (SCD) and develop risk prediction models. Models were derived from a retrospective cohort of pregnant women with SCD and constructed using generalised estimating equation logistic regression, with clustering by woman. Maternal event(s) consisted of acute anaemia; cardiac, pulmonary, hepatobiliary, musculoskeletal, skin, splenic, neurological or renal complications, multi‐organ failure, venous thromboembolism, admission‐requiring vaso‐occlusive events (VOE), red cell transfusion, mortality or hypertensive disorder of pregnancy. Fetal events included preterm birth, small‐for‐gestational‐age or perinatal mortality. Of 199 pregnancies, 71% and 45% resulted in adverse maternal and fetal outcomes respectively. Low first‐trimester haemoglobin, admission‐requiring VOE in the year before pregnancy, multiple transfusions before pregnancy, SCD genotype and previous cardiac complications predicted maternal risk. Younger age and SCD genotype allowed early prediction of fetal risk (model‐F1). Adding maternal event(s) and high lactate dehydrogenase enabled re‐assessment of fetal risk with advancing gestation (model‐F2). Models were well calibrated and moderately discriminative for maternal outcome (c‐statistic 0·81, cross‐validated value 0·79) and fetal outcome (model‐F1 c‐statistic 0·68, cross‐validated value 0·65; model‐F2 c‐statistic 0·72, cross‐validated value 0·68). The models will allow early identification of women with SCD at high risk of adverse events, permitting early targeted interventions and ongoing fetal risk re‐assessment enabling intensification of surveillance and optimisation of delivery timing.

Abstract
The objective of this study was to examine prior studies on maternal and neonatal outcomes with prophylactic compared with emergent blood transfusion in pregnant women with sickle cell disease. A review of the literature was performed. Twenty-one articles were identified and included in the analysis. A generalized linear mixed-effects model was used to analyze the outcomes. Pregnancy outcomes assessed were preeclampsia, pneumonia, pyelonephritis, pain crises, intrauterine growth restriction, neonatal death, perinatal death, and maternal mortality. Women who underwent emergent transfusion were more likely than women who underwent prophylactic transfusion to have the following adverse perinatal outcomes: preterm delivery (adjusted odds ratio [aOR 2.04], 95% confidence interval [CI] 1.14-3.63), pneumonia (aOR 2.98, 95% CI 1.44-6.15), pain crises (aOR 1.67, 95% CI 1.18-2.38), and perinatal death (aOR 1.84, 95% CI 1.06-3.07). Prophylactic transfusion should be reexamined as a potentially beneficial approach to the management of sickle cell disease in pregnancy.

Abstract
INTRODUCTION The aim of this study was to describe maternal and perinatal outcomes in pregnant women with sickle cell disease (SCD) followed at Santa Casa de Sao Paulo over a 10-year period (between 2010 and 2019). METHOD Fifty-five records of pregnancies were analyzed among 35 women with SCD. RESULTS Among 29 newborns, 19 (65.5%) were full-term and 10 pre-term; 24 (82.7%) caesareans and 5 (17.2%) natural births were observed. The mean gestational age at birth and mother`s age were 36.6 weeks (30-40) and 26.7 years (17-39), respectively. No maternal death was observed. The main maternal obstetric and non-obstetric complications were: pre-eclampsia and gestational diabetes, and vaso-occlusive crisis, urinary tract infection and acute chest syndrome, respectively. Twenty-six (47.0%) fetal deaths were observed, 24 being intrauterine fetal (14 early abortions, 10 late abortions and 2 stillbirths). Regarding the red blood cell transfusion history, 40 (72.7%) out of 55 pregnancies received transfusion. Pregnant women who received 6 or more transfusions throughout pregnancy had a significantly lower number of abortions, i.e., no cases of early abortion and only 1 case of late abortion, versus 14 and 9 cases in pregnancies with 0-5 transfusions, respectively. Despite advances in the management of SCD, pregnant women with SCD (particularly those with HbSS) are at a high risk for maternal and fetal complications, even though they are followed in reference centers. CONCLUSION The lower risk of intrauterine fetal death for those women who received more transfusions throughout pregnancy observed in the current study leads us once more to raise the need for prospective, multicenter, randomized trials to determine whether the potential benefits balance the risks of prophylactic transfusions.

Abstract
BACKGROUND Sickle cell disease (SCD) is a multisystem disease characterised by vaso-occlusive crisis, chronic anaemia and a shorter lifespan. More patients with SCD are living till reproductive age and contemplating pregnancy. Pulmonary complications in pregnancy are significant causes of maternal morbidity and mortality but yet this has not been systematically quantified. A systematic review and meta-analysis were conducted to quantify the association between SCD and pulmonary complications in pregnancy. METHODS MEDLINE, EMBASE, Web of Science, Cochrane and Maternity and Infant Care databases were searched for publications between January 1998 and April 2019. Observational studies involving at least 30 participants were included. Random-effects models were used for statistical meta-analysis. FINDINGS Twenty-two studies were included in the systematic review and 18 in the quantitative analysis. The meta-analysis included 3964 pregnancies with SCD and 336 559 controls. Compared with women without SCD, pregnancies complicated by SCD were at increased risk of pulmonary thromboembolism (relative risk (RR) 7.74; 95% CI 4.65 to 12.89). The estimated prevalence of acute chest syndrome and pneumonia was 6.46% (95% CI 4.66% to 8.25%), with no significant difference between the HbSS and HbSC genotypes (RR 1.42; 95% CI 0.90 to 2.23). INTERPRETATION This meta-analysis highlighted a strong association between SCD and maternal pulmonary complications. Understanding the risks of and the factors associated with pulmonary complications would aid preconceptual counselling and optimal management of the condition in pregnancy, thereby reducing associated maternal morbidity and mortality.

Abstract
Purpose: To evaluate the outcome of pregnancies among women affected by sickle cell disease (SCD).Material and methods: This retrospective comparative cohort study was carried out between 1 January 2014 and 31 December 2018. The files of pregnant women with and without SCD were analyzed. The main variables recorded included parity, diseases that occurred during pregnancy, maternal and gestational ages at delivery, mode of delivery, birthweight and Apgar score. Data were analyzed using SPSS 21.0. Fisher exact test and the t-test was used for comparison. p < .05 was considered statistically significant.Results: Our frequency of delivery of women with SCD was 0.1% (35/34,895). Significant complications associated with SCD were maternal anemia (RR = 17.00, 95%CI = 5.35-53.99), intra-uterine fetal demise (RR = 12.00, 95%CI = 1.39-103.22), low birthweight (RR = 2.52, 95%CI = 1.50-4.25), neonatal asphyxia (RR = 7.70, 95%CI = 2.57-22.99), transfer of newborn to the neonatal intensive care unit (RR = 3.42, 95%CI = 1.94-6.03), early neonatal death (RR = 4.56, 95%CI = 1.09-19.10), and maternal postpartum severe anemia (RR = 4.50, 95%CI = 1.36-14.87).Conclusions: Pregnancies amongst women with SCD are still associated with increased risk of maternal anemia as well as perinatal morbidity and mortality despite frequent blood transfusion. Therefore, new strategies should be explored to improve such pregnancies.

Abstract
Pregnancy in women with sickle cell disease (SCD) is associated with increased maternal and fetal morbidity and mortality. Outcomes vary widely owing to methodological limitations of clinical studies, but overall, hypertensive disorders of pregnancy, venothromboembolism, poor fetal growth, and maternal and perinatal mortality are increased globally. Few therapeutic interventions have been explored other than prophylactic and selective transfusion therapy. Unfortunately, existing data are limited, and it remains unclear whether prophylactic use of chronic transfusions will improve pregnancy outcomes. Management of pregnant women with SCD is best accomplished with a multidisciplinary team that includes a sickle cell expert and an obstetrician familiar with high-risk pregnancies. Women with SCD should have individualized care plans that outline management of acute pain and guidelines for transfusion therapy. Neonates require close monitoring for neonatal abstinence syndrome and hemolytic disease of the newborn. Ideally all young women with SCD will have a "reproductive life plan" developed as a component of preconception counseling and health promotion. Research leading to improved pregnancy management focused on diminishing adverse maternal and neonatal outcomes is overdue. International collaborations should be considered to improve subject recruitment and foster timely completion of clinical trials. Additional therapeutic interventions outside of transfusion therapy should be explored.

Abstract
OBJECTIVE to determine the beneficial role of Fetal Hemoglobin (FHb) and alpha-thal on fetal and maternal morbidity during pregnancy in sickle cell patients. STUDY SITE the study was conducted at the sickle cell center of Kinshasa between 2008 and 2018. SETTING AND STUDY POPULATION this is a documentary and analytical study that included 980 deliveries of homozygous sickle cell patients. METHODS the diagnosis of SCD and the quantification of FHb were performed with the capillary electrophoresis technique. The molecular test confirmed the diagnosis of SCD. The diagnosis of alpha-thal was made with the multiplex ligation-dependent probe amplification (MLPA) technique. Sickle cell pregnancies were followed according to the protocol of care in force in the University of Kinshasa Hospital service. The variables of interest were: hematological variables, sickle cell crises during pregnancy, maternal and fetal complications. STATISTICS statistical analyses were performed with SPSS 20.0 software. Means and standard deviations were compared with the Student's t and ANOVA tests. The value of p <0.05 was considered the significance level. RESULTS the Hb-SS / alpha-thal and HbSS / HPFH genotypes were observed in 101 and 121 women, respectively. Otherwise, 758 women had HbSS genotype. The morbidity related to sickle cell complications in the mother and fetus were less frequent in the Hb-SS / alpha-thal and HbSS / HPFH groups than in HB-SS group. The differences were statistically significant. CONCLUSION this study showed a significant protective effect of alpha-thal and HPFH during pregnancy in sickle-cell pregnant women.
