RESUMEN

G3P2L1, 28+4 weeks of gestation rhesus (Rh) isoimmunised pregnant women, was referred with trichorionic triamniotic triplet pregnancy with Rh antibody titres of 1:32. Nuchal translucency and anomaly scan were within normal limits with no major malformation for any of the fetuses. Obstetric colour Doppler with middle cerebral artery peak systolic volume revealed foetal anaemia in all three fetuses having velocities corresponding to around 1.5 times the median. Decision of intrauterine transfusion of blood to all three fetuses was taken. Access to fetuses was challenging and expertise in interventional ultrasound was required for transfusion. The patient tolerated the procedure well and eventually went on to deliver uneventfully at 34 weeks of gestation for worsening pre-eclampsia. After birth, all three triplets received triple-surface intensive phototherapy and intravenous immunoglobulin at a dosage of 1 g/kg. Phototherapy was gradually reduced and discontinued within 72 hours, and the infants were discharged from the neonatal intensive care unit at 96 hours of age.

RESUMEN

INTRODUCTION: Fetal anemia from hemolytic disease treated by intrauterine transfusion (IUT) can be performed by intraperitoneal, intracardiac, and intravascular transfusion (IVT). Objective of our study was to compare different transfusion techniques. METHODS: Retrospective review of IUT secondary to red cell alloimmunization was conducted at eight international centers from 2012 to 2020. Severe anemia suspected if middle cerebral artery peaks systolic velocity ≥1.5 multiples of the median. Demographic, delivery, and postnatal variables were analyzed. RESULTS: Total of 344 procedures, 325 IVT and 19 other techniques (non-IVT) included. No difference in demographics, history of stillbirth (20.5 vs. 15.8%, p = 0.7), prior pregnancy IUT (25.6 vs. 31.6%, p = 0.5) or neonatal transfusion (36.1 vs. 43.8%, p = 0.5). At first IUT, non-IVT had higher hydrops (42.1% vs. 20.4%, p = 0.03), lower starting hematocrit (13.3% [±6] vs. 17.7% [±8.2], p = 0.04), and trend toward lower gestational age (24.6 [20.1-27] vs. 26.4 [23.2-29.6] weeks, p = 0.08). No difference in birthweight, neonatal phototherapy, exchange, or simple transfusion was observed. CONCLUSION: This is one of the largest studies comparing techniques to treat fetal anemia. IVT was most performed, other techniques were more likely performed in hydrops, and lower starting hematocrit was seen. Neither technique affected outcomes. This study may suggest that physician's experience may be the strongest contributor of outcomes.

RESUMEN

Red blood cell (RBC) alloimmunisation with anti-D and anti-K comprise the majority of cases of fetal haemolytic disease requiring intrauterine red cell transfusion (IUT). Few studies have investigated which haematological parameters can predict adverse fetal or neonatal outcomes. The aim of the present study was to identify predictors of adverse outcome, including preterm birth, intrauterine fetal demise (IUFD), neonatal death (NND) and/or neonatal transfusion. We reviewed the records of all pregnancies alloimmunised with anti-K and anti-D, requiring IUT over 27 years at a quaternary fetal centre. We reviewed data for 128 pregnancies in 116 women undergoing 425 IUTs. The median gestational age (GA) at first IUT was significantly earlier for anti-K than for anti-D (24·3 vs. 28·7 weeks, P = 0·004). Women with anti-K required more IUTs than women with anti-D (3·84 vs. 3·12 mean IUTs, P = 0·036) and the fetal haemoglobin (Hb) at first IUT was significantly lower (51.0 vs. 70.5 g/l, P = 0·001). The mean estimated daily decrease in Hb did not differ between the two groups. A greater number of IUTs and a slower daily decrease in Hb (g/l/day) between first and second IUTs were predictive of a longer period in utero. Earlier GA at first IUT and a shorter interval from the first IUT until delivery predicted IUFD/NND. Earlier GA and lower Hb at first IUT significantly predicted need for phototherapy and/or blood product use in the neonate. In the anti-K group, a greater number of IUTs was required in women with a higher titre. Furthermore, the higher the titre, the earlier the GA at which an IUT was required in both groups. The rate of fall in fetal Hb between IUTs decreased, as the number of transfusions increased. Our present study identified pregnancies at considerable risk of an unfavourable outcome with anti-D and anti-K RBC alloimmunisation. Identifying such patients can guide pregnancy management, facilitates patient counselling, and can optimise resource use. Prospective studies can also incorporate these characteristics, in addition to laboratory markers, to further identify and improve the outcomes of these pregnancies.

RESUMEN

OBJECTIVES: With improved access to intrauterine transfusion (IUT), more fetuses with haemoglobin Bart's hydrops fetalis (HBHF; homozygous α0-thalassaemia) will survive. DESIGN: To evaluate the long-term outcome of affected fetuses with and without IUT in Ontario, Canada, we retrospectively collected data on IUTs and pregnancy outcomes in all cases of HBHF, from 1989 to 2014. Clinical outcome and neurocognitive profiles of long-term survivors were also collected and compared with data from 24 patients with transfusion-dependent ß-thalassaemia (TDT-ß). RESULTS: Of the 99 affected pregnancies (93 prenatally diagnosed), 68 resulted in miscarriage or elective termination of pregnancy. Twelve mothers (12%) continued their pregnancies without IUT, and none of those newborns survived the first week of life. All 13 fetuses that received IUT(s) were live-born, but 3 died due to severe hydrops at birth and 1 died due to infection. The remaining nine survivors, in comparison with TDT-ß patients, had earlier iron overload requiring iron chelation therapy. Endocrinopathies and short stature were more frequent in these patients. Neurocognitive outcome was not significantly affected in five patients who were assessed, and none were diagnosed with intellectual impairment. In three patients, MRI studies demonstrated brain white matter changes in keeping with 'silent' ischaemic infarcts. CONCLUSIONS: In patients with HBHF, IUT is associated with improved survival. While acceptable neurocognitive outcome can be expected, these patients have more clinical complications compared with their TDT-ß counterparts. The clinical and neurocognitive outcomes of HBHF should be discussed in detail when counselling and offering IUT for patients.

RESUMEN

We aimed to investigate the effect of intrauterine administration of autologous hCG-activated PBMCs in RIF women with low Th-17/Treg cell ratio. 248 women with a history of implantation failure volunteered to receive PBMC-therapy. After immunologic consultation and doing flow cytometry analysis, 100 women with at least three IVF/ET failure who had low Th-17/Treg ratio in comparison with healthy control were enrolled in this study. These 100 patients were randomly divided into two groups as PBMC receiving (n = 50) and controls (n = 50). Then PBMCs were obtained from patients and treated with hCG for 48 h. Afterward, PBMCs were administered into the uterine cavity of the patient in the study group, two days before ET. The concentration of inflammatory cytokines was examined in the supernatant of cultured PBMCs after 2, 24, and 48 h of incubation using the ELISA method. The frequency of Th-17, Treg, and the Th-17/Treg ratio was significantly lower in RIF women than the healthy controls (P < 0.0001). The secretion of inflammatory cytokines was significantly higher after 48 h compared to 2 and 24 h (P < 0.0001). The pregnancy and live birth rate were significantly increased in women undergoing the PBMC-therapy compared to control (PBS-injecting) group (P = 0.032 and P = 0.047, respectively). The miscarriage rate was considerably lower in PBMC-therapy group (P = 0.029). Our findings suggest that intrauterine administration of autologous in vitro hCG-activated PBMCs improves pregnancy outcomes in patients with at least three IVF/ET failures.

RESUMEN

Prior studies have provided conflicting results regarding the use of platelet-rich plasma (PRP) in women undergoing in-vitro fertilization (IVF) or intracytoplasmic injection (ICSI). The objective of this study was to evaluate the effect of the intrauterine infusion of PRP on the outcome of embryo transfer (ET) in women undergoing IVF/ICSI. We searched databases, including PubMed, Embase, Scopus, Web of Science, and the Cochrane Database of Clinical Trials (CENTRAL). Meta-analysis using a random-effects model was performed to calculate the pooled estimates. Seven studies involving 625 patients (311 cases and 314 controls) were included. The probability of chemical pregnancy (n = 3, risk ratio (RR): 1.79, 95 % confidence intervals (CI): 1.29, 2.50; P < 0.001, I2 = 0 %), clinical pregnancy (n = 7, RR: 1.79, 95 % CI: 1.37, 2.32; P < 0.001, I2 = 16 %), and implantation rate (n = 3, RR: 1.97, 95 % CI: 1.40, 2.79; P < 0.001, I2 = 0 %) was significantly higher in women who received PRP compared with control. There was no difference between women who received PRP compared with control group regarding miscarriage (RR: 0.72, 95 % CI: 0.27, 1.93; P = 0.51, I2 = 0 %). Following the intervention, endometrial thickness increased in women who received PRP compared to control group (SMD: 1.79, 95 % CI: 1.13, 2.44; P < 0.001, I2 = 64 %). The findings of this systematic review suggest that PRP is an alternative treatment strategy in patients with thin endometrium and recurrent implantation failure (RIF). Further prospective, large, and high quality randomized controlled trials (RCTs) are needed to identify the subpopulation that would most benefit from PRP.

RESUMEN

One in every nine couples suffers from implantation defects and pregnancy failures. In spite of many contributions that ART has given to infertility treatment, there are many reports of the failure of ART. Therefore, scientists suggested many complementary therapies for use besides ART to improve the quality of infertility treatments. Intrauterine PBMC-therapy is one of these complementary therapies that were used before IVF. Studies that examined PBMC treatment in women with at least three IVF/ET failure were included in this review. These studies involved RCT and quasi-experimental (non-randomized experimental) studies. A three-step search strategy was used for published and unpublished clinical trials written in English and Persian. No time limitation was set for studies. Study selection according to the inclusion criteria and methodological quality assessment and data extraction were done by two independent reviewers, which result in five studies being included (two RCTs and three quasi-experimental studies). Finally, all of these article extracted data were pooled in a statistical meta-analysis. Findings demonstrated that implantation, pregnancy and live birth rate were statistically increased and the miscarriage rate was significantly decreased in the PBMC-treated group than that non-treated group. In conclusion, based on the evidence, PBMCs can be an effective therapeutic approach in women with at least three IVF/ET failure and lacking initial inflammation that is essential for implantation.

RESUMEN

Intrauterine transfusion is one of the mainstays of treatment in isoimmunised pregnancies guided by the changes in middle cerebral artery Doppler of the fetus. The common postnatal complications associated with Rh isoimmunisation are high unconjugated bilirubin requiring blood exchange transfusions, cholestasis due to bile inspissation, thrombocytopenia and anaemia. Hyperferritinaemia is an uncommon adverse effect observed in Rh isoimmunised pregnancies. In this case report, we describe the clinical course of a Rh isoimmunised neonate with hyperferritinaemia and transfusion acquired cytomegalovirus disease which resolved. Iron chelation therapy was not necessary.

RESUMEN

BACKGROUND: Minor red blood cell antibodies are becoming a more common cause of hemolytic disease of the newborn. Anti-U are a rare alloantibody found almost exclusively in people of black descent. There is limited experience to guide the management of pregnancies complicated by anti-U. Furthermore, there is often no suitable cross-matched blood available for transfusion of a patient with anti-U. CASE REPORT: A 21-year-old P0G1 presented at 25 weeks' gestation with D- disease in pregnancy. She had a significant indirect antiglobulin test titer of 512. Anti-U were identified and no suitable cross-matched blood was available. Maternal blood was prepared for autologous intrauterine fetal transfusion. Two such transfusions were performed. RESULTS: A healthy fetus delivered at 32 weeks that did not require phototherapy or an exchange transfusion. CONCLUSION: Autologous transfusion of prepared maternal blood provides a safe option for intrauterine fetal therapy in pregnancies complicated by rare alloantibodies.

RESUMEN

OBJECTIVE: To compare in utero exchange transfusions (IUET) and in utero simple transfusions (IUST) for the treatment of fetal anemia resulting from red blood cell fetomaternal incompatibility. STUDY DESIGN: Retrospective comparative study from January 2006 through December 2011. The two techniques were compared for effectiveness, complications, and neonatal outcomes. RESULTS: 36 patients had 87 IUETs and 85 patients 241 IUSTs. Gestational age at the first transfusion was similar in both groups (IUET: 27±3.8 weeks; IUST: 27±4.7 weeks; NS) as was the initial fetal hemoglobin level (IUET: 6.4±2.8g/dL; IUST: 6.0±2.5g/dL; NS). No significant differences were noted for postprocedure complications or efficacy. The daily drop in hemoglobin level was similar in both groups (IUET: 0.41±0.23g/dL/day; IUST: 0.44±0.17g/dL/day; NS) as were the time intervals between two procedures. Gestational age at birth was earlier in the IUET group (34.4±1.3 weeks vs 35.5±1.8 weeks; p<0.001), but the postnatal transfusions or exchange transfusions rates and the duration of intensive phototherapy did not differ. No significant differences were noted for the overall survival rates (IUET: 100%; IUST: 96.4%; p>0.99). CONCLUSION: IUET does not appear to provide any benefits compared with IUST, neither to be associated with a higher complication rate. The choice of the technique depends on availability of packed blood cells with high hematocrit (70-80%).

RESUMEN

UNLABELLED: In-utero transfusion is now well under control and improves the survival of foetuses monitored for fetal anemia with a survival rate of more than 80 %. The aim was to evaluate short-term neonatal outcome after fetal severe anemia managed by intrauterine transfusions. We did a retrospective study of all neonates born after management of severe fetal anemia (n = 93) between January 1999 and January 2013 in our regional center. The two main causes of anemia were maternal red blood cell alloimmunization (N = 81, 87 %) and Parvovirus B19 infection (N = 10, 10.8 %). In the alloimmunization group, phototherapy was implemented in 85.2 % of cases with a maximum level of bilirubin of 114.4 ± 60.7 (mg/dl). Transfusion and exchange transfusion were, respectively, required in 51.9 % and in 34.6 % of cases. One neonate presented a convulsive episode, and we observed three neonatal deaths. In the parvovirus group, none of the child had anemia at birth and no management was necessary. CONCLUSION: Contemporary management of Rhesus disease is associated with encouraging neonatal outcomes. In case of Parvovirus infection, no specific management is necessary at. But, in all cases of fetal anemia, children should be followed up with particular attention to neurologic development. WHAT IS KNOWN: • In-utero transfusion is now well under control and improves the survival of fetuses monitored for fetal anemia. • Limited studies are available on the effect of IUT on postnatal outcome in infants with a history of fetal anemia. What is New: • Contemporary management of severe Rhesus disease is associated with encouraging neonatal outcomes. • The majority of infants can be managed with phototherapy and a limited number of top-up transfusions and exchange transfusions. In case of Parvovirus infection, the short-term neonatal outcome is excellent.

RESUMEN

BACKGROUND: The management of pregnant women with anti-Jsb is challenging due to the paucity of antigen-negative blood for fetal and neonatal transfusion. CASE REPORT: A 29-year-old woman with anti-Jsb was referred for assessment of recurrent fetal losses. With the presence of the sister as a historically matched donor, she was planned for active surveillance for fetal anemia during pregnancy. STUDY DESIGN AND METHODS: The fetus remained well until 21 weeks of gestation when signs of fetal anemia and early hydrops fetalis were noted. Anti-Jsb titer was at 128. The sister's red blood cells (RBCs) were cross-match incompatible. Urgent intrauterine transfusion (IUT) was performed with washed irradiated maternal RBCs, donated after cessation of heparin. The mother was given intravenous iron (IV-Fe) and continued on weekly recombinant human erythropoietin (rHu-EPO). RESULTS: Repeated IUTs were needed every 1 to 3 weeks. Throughout a 7-week period, three maternal donations were performed with total donated whole blood volume of 1250 mL, supporting four IUTs. At 29 weeks of gestation, the procedure was complicated by umbilical cord hematoma necessitating urgent cesarean section. A male newborn was delivered, transfused at birth, and subsequently treated with phototherapy and five top-up transfusions. CONCLUSION: This case represents a successful example of managing hemolytic disease of the fetus due to a rare antibody using maternal blood. It also supports previous data on safety of maternal donations during pregnancy and the use of combination of rHu-EPO and IV-Fe as a supportive measure.

RESUMEN

BACKGROUND: This study, conducted in the tertiary Foetal Medicine Unit at St Michael's Hospital, Bristol, was designed to obtain information regarding neonatal outcomes of pregnancies affected by haemolytic disease of the foetus and newborn and managed by intrauterine transfusion, and to determine whether a change in intrauterine transfusion protocol in 2004 had improved safety. The new protocol included attendance of two Foetal Medicine Unit consultants, foetal sedation and use of the intrahepatic vein as an alternative route to placental cord insertion if deemed safer. MATERIALS AND METHODS: Data for pregnancies affected by haemolytic disease of the foetus and newborn as a result of haemolytic red cell alloimmunisation and managed with intrauterine transfusion at St Michael's Hospital between 1999 and 2009 were retrospectively collected using local databases, and medical note review. RESULTS: Overall, 256 relevant intrauterine transfusions were performed. The median number of intrauterine transfusions per pregnancy was two. Ninety-three per cent of the live deliveries had 5-minute APGAR scores ≥9 and 98% were admitted to a Neonatal Intensive Care Unit/Special Care Baby Unit, requiring phototherapy (96%), top-up transfusions (44%: 23.2% immediate, 13.4% late, 7.3% both), and exchange transfusion (37%). An association was found between increased intrauterine transfusion number and reduced phototherapy duration and hospital admission: each additional intrauterine transfusion reduced the duration of phototherapy by 16% (95% CI: 0.72-0.98), and Neonatal Intensive Care Unit/Special Care Baby Unit admission by 44% (95% CI: 0.48-0.66). Following the change in intrauterine transfusion protocol, there was a significant reduction in the number of emergency Caesarean sections occurring directly after an intrauterine transfusion (n =5 vs 0; P =0.02). The foetal loss rate within 48 hours of an intrauterine transfusion was 1.9% per pregnancy, or 0.8% per intrauterine transfusion: no losses occurred under the new protocol (n =3 vs 0; P = NS). DISCUSSION: Although the majority of neonates required admission to a Neonatal Intensive Care Unit/Special Care Baby Unit and phototherapy, the medium-term outcomes were positive. Importantly, the safety of the intrauterine transfusion procedure has improved significantly since the change in protocol.

RESUMEN

OBJECTIVE: To evaluate neonatal outcomes among a homogeneous group of fetuses with severe hydrops treated with intrauterine transfusion (IUT). METHODS: In a prospective study at Dokuz Eylul University School of Medicine, Izmir, Turkey, outcomes were compared for 35 IUTs carried out between 2005 and 2010 in 19 pregnancies that were complicated by Rhesus D hemolytic disease with severely hydropic fetuses. RESULTS: There was no correlation between the number of IUTs and the duration of phototherapy or number of exchange transfusions. After delivery, 36% (7/19) of neonates tested positive in a direct Coombs test and their requirement for exchange transfusion was higher than that of neonates who tested negative. The neonatal survival rate was 73.7%. Admission to the neonatal intensive care unit was 78%, and the median duration of neonatal unit stay was 4 days (range, 1-77 days). Only 1 newborn had hearing impairment. CONCLUSION: IUT is a unique, gold standard treatment for severely hydropic fetuses. When treated optimally with IUT, fetuses with severe hydrops showed no increased risk of neurodevelopmental abnormalities. Factors affecting the survival of hydropic fetuses after IUT, and whether the number of IUTs performed affects the number of exchange transfusions required remain unclear.

RESUMEN

The aim of this retrospective study was to find out the effect of change in the management of red cell alloimmunized pregnancies from conventional method of amniocentesis to the Doppler assessment of middle cerebral artery peak systolic velocity (MCA-PSV). There were 29 alloimmunized pregnancies affected by red cell antibodies. Ten cases were managed by amniocentesis and another 19 were managed by MCA-PSV measurements. The antenatal management and perinatal outcome of both groups are presented. This study suggests that the non-invasive monitoring should be the method of choice to monitor alloimmunized pregnancies.

RESUMEN

OBJECTIVES: To evaluate perinatal management and neurological outcome in a group of infants born with Rhesus fetomaternal allo-immunization. PATIENTS AND METHODS: Between 1 January and 31 December 2005, all newborns admitted to neonatal unit of Rouen tertiary centre for Rhesus hemolytic disease were included in a retrospective study and divided in two groups. The newborns who were treated with intrauterine transfusion are in the group 1 and those who needed only postnatal treatment in the group 2. In each case, were considered antenatal management (ultrasonographic data, middle cerebral artery peak systolic velocity, intrauterine transfusion), postnatal treatment (phototherapy, exchange transfusion, transfusion requirements) and neurological outcome. RESULTS: Among 42 cases of Rhesus allo-immunization observed in six years, 28 newborns (67%) were admitted for neonatal cares. No case of fetal hydrops was noted. But 16/28 (57%) were preterm with a median term of 35 weeks gestation (32-36 weeks). In group 1 of six infants who had received intrauterine transfusion (IUT), only one (17%) needed postnatal exchange transfusion, and all six received one to three blood transfusions after their birth. In group 2 of 22 infants who did not receive IUT, 6/22 (27%) needed postnatal exchange and 18/22 (82%) of them received one to four blood transfusions. Phototherapy duration and albumin requirements were similar in both groups. Three deaths occurred, one due to necrotizing enterocolitis and the other two later on due to sudden infant death and fulminant meningococcemia. Neurological outcome of the remaining 25 children was normal. DISCUSSION AND CONCLUSION: Rhesus alloimmunization remain a situation at risk. Neonatal clinical presentation is less severe than previously described due to improvement in antenatal management. Infants required less postnatal exchange transfusion when they received intrauterine transfusion but more frequent blood transfusions.

RESUMEN

OBJECTIVE: To study the short-term morbidity in Rhesus hemolytic disease of infants treated either with or without intrauterine transfusions (IUT). STUDY DESIGN: All term and near term infants (gestational age > or = 36 weeks) with neonatal Rhesus hemolytic disease admitted to our center between January 2000-March 2005 were retrospectively included in the study. We recorded the duration of phototherapy, the need of exchange transfusions, and the need of top-up red blood cell transfusions until 6 months of age. RESULTS: A total of 89 infants were included, of whom 52 received at least one IUT. Duration of phototherapy in the IUT and no-IUT group was 3.8 and 5.1 days, respectively (P = .01). The percentage of infants requiring an exchange transfusion in the IUT group was 71% compared to 65% in the no-IUT group (P = .64). The percentage of infants requiring a top-up transfusion in the IUT and no-IUT group was 77% and 26.5%, respectively (P < .01). CONCLUSION: Infants with Rhesus hemolytic disease treated with IUT required less days of phototherapy and more top-up red blood cell transfusions than neonates without IUT. However, the need for exchange transfusion was similar in both groups.

RESUMEN

La enfermedad hemolítica por anti D es una grave problemática de nuestro medio que es reconocido como causa de muerte perinatal. Conociendo que las pacientes con enfermedad hemolítica severa, las posibilidades de viabilidad fetal son nulas a pocas semanas de gestación donde otros tratamientos no fueron suficientes, nuestro trabajo demuestra que la transfusión intrauterina por cordocentesis (TIUPC) es una técnica que logra alta expectativa de vida ya que permite no solo reabsorber el hidrops fetal alcanzando embarazos a término con fetos viables, sino también evolución de los recién nacidos sin necesidad de internaciones prolongadas, con menor costo, en relación a los gastos ocasionados por el manejo multidisciplinario que requerían los neonatos sin este tratamiento.
