Abstract
BACKGROUND Advances in postnatal care for hemolytic disease of the fetus and newborn (HDFN) have occurred over the past decades, but little is known regarding the frequency of postnatal treatment and the clinical outcomes of affected neonates. Most studies reporting on HDFN originate from high-income countries or relatively large centers, but important differences between centers and countries may exist due to differences in prevalence and available treatment options. We therefore aimed to evaluate the postnatal treatment landscape and clinical outcomes in neonates with Rhesus factor D (Rh(D))- and/or K-mediated HDFN and to provide recommendations for future research. METHODS We conducted a rapid literature review of case reports and series, observational retrospective and prospective cohort studies, and trials describing pregnancies or children affected by Rh(D)- or K-mediated HDFN published between 2005 and 2021. Information relevant to the treatment of HDFN and clinical outcomes was extracted. Medline, ClinicalTrials.gov and EMBASE were searched for relevant studies by two independent reviewers through title/abstract and full-text screening. Two independent reviewers extracted data and assessed methodological quality of included studies. RESULTS Forty-three studies reporting postnatal data were included. The median frequency of exchange transfusions was 6.0% [interquartile range (IQR): 0.0-20.0] in K-mediated HDFN and 26.5% [IQR: 18.0-42.9] in Rh(D)-mediated HDFN. The median use of simple red blood cell transfusions in K-mediated HDFN was 50.0% [IQR: 25.0-56.0] and 60.0% [IQR: 20.0-72.0] in Rh(D)-mediated HDFN. Large differences in transfusion rates were found between centers. Neonatal mortality amongst cases treated with intrauterine transfusion(s) was 1.2% [IQR: 0-4.4]. Guidelines and thresholds for exchange transfusions and simple RBC transfusions were reported in 50% of studies. CONCLUSION Most included studies were from middle- to high-income countries. No studies with a higher level of evidence from centers in low-income countries were available. We noted a shortage and inconsistency in the reporting of relevant data and provide recommendations for future reports. Although large variations between studies was found and information was often missing, analysis showed that the postnatal burden of HDFN, including need for neonatal interventions, remains high.

Abstract
PURPOSE Fetal alloimmune hemolytic anemia (AHA) resulting from maternal antibodies against fetal erythrocytes may require fetal administration of immunoglobulin-G (IgG) via invasive methods. IgG can reach the fetal circulation after transamniotic fetal immunotherapy (TRAFIT). We sought to both develop a model of AHA and to test TRAFIT as a potential treatment. METHODS Sprague-Dawley fetuses (n = 113) received intra-amniotic injections on gestational-day 18 (E18, term = E21) of either saline (control; n = 40), anti-rat-erythrocyte antibodies (AHA; n = 37), or anti-rat-erythrocyte antibodies plus IgG (AHA + IgG; n = 36). At term, blood was procured for red blood count (RBC), hematocrit, or ELISA for inflammatory markers. RESULTS There was no difference in survival [95% (107/113)] across groups (p = 0.87). Both hematocrit and RBC were significantly lower in the AHA group than controls (p < 0.001). Although still significantly lower than controls (p < 0.001), both hematocrit and RBC significantly increased in AHA + IgG group compared to AHA alone (p < 0.001). Pro-inflammatory TNF-α and IL1-β were significantly elevated from controls in the AHA group, but not in AHA + IgG (p < 0.001-0.159). CONCLUSIONS Intra-amniotic injection of anti-rat-erythrocyte antibodies can reproduce manifestations of fetal AHA, constituting a practical model of this disease. Transamniotic fetal immunotherapy with IgG reduces anemia in this model and may emerge as a new minimally invasive means of treatment. TYPE OF STUDY Animal and laboratory study. LEVEL OF EVIDENCE N/A (animal and laboratory study).

Abstract
BACKGROUND Prevention of pregnancy-related alloimmunization and the management of hemolytic disease of the fetus and newborn (HDFN) has significantly improved over the past decades. Considering improvements in HDFN care, the objectives of this systematic literature review were to assess the prenatal treatment landscape and outcomes of Rh(D)- and K-mediated HDFN in mothers and fetuses, to identify the burden of disease, to identify evidence gaps in the literature, and to provide recommendations for future research. METHODS We performed a systematic search on MEDLINE, EMBASE and clinicaltrials.gov. Observational studies, trials, modelling studies, systematic reviews of cohort studies, and case reports and series of women and/or their fetus with HDFN caused by Rhesus (Rh)D or Kell alloimmunization. Extracted data included prevalence; treatment patterns; clinical outcomes; treatment efficacy; and mortality. RESULTS We identified 2,541 articles. After excluding 2,482 articles and adding 1 article from screening systematic reviews, 60 articles were selected. Most abstracted data were from case reports and case series. Prevalence was 0.047% and 0.006% for Rh(D)- and K-mediated HDFN, respectively. Most commonly reported antenatal treatment was intrauterine transfusion (IUT; median frequency [interquartile range]: 13.0% [7.2-66.0]). Average gestational age at first IUT ranged between 25 and 27 weeks. weeks. This timing is early and carries risks, which were observed in outcomes associated with IUTs. The rate of hydrops fetalis among pregnancies with Rh(D)-mediated HDFN treated with IUT was 14.8% (range, 0-50%) and 39.2% in K-mediated HDFN. Overall mean ± SD fetal mortality rate that was found to be 19.8%±29.4% across 19 studies. Mean gestational age at birth ranged between 34 and 36 weeks. CONCLUSION These findings corroborate the rareness of HDFN and frequently needed intrauterine transfusion with inherent risks, and most births occur at a late preterm gestational age. We identified several evidence gaps providing opportunities for future studies.

Abstract
INTRODUCTION Hemolytic disease of the fetus and newborn (HDFN) is a condition caused by maternal alloantibodies against fetal red blood cells (RBCs) that can cause severe morbidity and mortality in the fetus and newborn. Adequate screening programs allow for timely prevention and intervention resulting in significant reduction of the disease over the last decades. Nevertheless, HDFN still occurs and with current treatment having reached an optimum, focus shifts toward noninvasive therapy options. AREAS COVERED This review focusses on the timely identification of high risk cases and antenatal management. Furthermore, we elaborate on future perspectives including improvement of screening, identification of high risk cases and promising treatment options. EXPERT OPINION In high-income countries mortality and morbidity rates due to HDFN have drastically been reduced over the last decades, yet worldwide anti-D mediated HDFN still accounts for 160,000 perinatal deaths and 100,000 patients with disabilities every year. Much of these deaths and disabilities could have been avoided with proper identification and prophylaxis. By implementing sustainable prevention, screening, and disease treatment measures in all countries this will systemically reduce unnecessary perinatal deaths. There is a common responsibility to engage in this cause.

Abstract
PURPOSE We sought to determine whether the amniotic cavity/fluid could be an attainable route of administration of therapeutic antibodies to the fetus/neonate. METHODS Time-dated pregnant dams (n = 9) received volume-matched intra-amniotic injections of either saline (n = 29), or different concentrations of a human IgG that lacked homology with rodents: 5 mg/mL (n = 28); 10 mg/mL (n = 28); or 15 mg/mL (n = 24). At term, the presence of the IgG was quantified by ELISA in the serum, bone marrow, spleen, thymus, and brain of all neonates, and in the maternal serum. Statistical analysis was by median regression with significance set at Bonferroni-adjusted p<0.008. RESULTS Overall fetal survival was 83% (90/109), with no difference between the groups. Human IgG was detected in the serum, bone marrow, spleen, thymus, and brain of all fetuses for all three injected concentrations, but not in the saline injected controls (p<0.001). A dose dependent relationship between injection concentration and final IgG load was noted in the bone marrow, spleen, and thymus (p = 0.004 to <0.001). Human IgG was also detected in maternal serum. CONCLUSIONS IgG antibodies can reach high levels in the fetal/neonatal circulation after simple intra-amniotic administration in a healthy rodent model. Transamniotic fetal immunotherapy (TRAFIT) may become a practicable strategy for the perinatal management of select diseases.

Abstract
Fetal therapy has been defined as any therapeutic intervention either invasive or noninvasive for correcting or treating any fetal malformation or condition. Invasive fetal therapy have its own set of maternal and fetal complications and invasive approach is not feasible in many of fetal conditions that are candidate for fetal therapy. Many such fetal conditions have been treated successfully by medical or noninvasive management. In medical fetal therapy, mothers are treated with medications which are transferred to fetus through placenta and exert positive effect on the fetus, thus avoiding complications that are seen secondary to invasive fetal therapy. The fetal conditions that have been managed with medical therapy includes fetal and neonatal alloimmune thrombocytopenia, neural tube defect, congenital adrenal hyperplasia, perinatal infections, respiratory distress syndrome, inborn error of metabolism, and congenital cystic adenomatoid malformation. This review will cover the medical or noninvasive aspect of fetal therapy and will highlight the progress made in the management of these fetal conditions.

Abstract
Haemolytic disease of the fetus and newborn (HDFN) remains an important cause of fetal mortality with potential neonatal and longer-term morbidity. HDFN is caused by maternal red cell alloimmunisation, with IgG antibodies crossing the placenta to destroy fetal erythroid cells expressing the involved antigen. Intrauterine fetal blood transfusion is the therapy of choice for severe fetal anaemia. Despite a strong evidence base and technical advances, invasive fetal therapy carries risk of miscarriage and preterm birth. Procedure-related risks are increased when invasive, in utero transfusion is instituted prior to 22 weeks to treat severe early-onset fetal anaemia. This review focuses upon this cohort of HDFN and discusses intravenous immunoglobin (IVIg) and novel monoclonal antibody (M281, nipocalimab) treatments which, if started at the end of the first trimester, may attenuate the transplacental passage and fetal effects of IgG antibodies. Such therapy has the ability to improve fetal survival in this severe presentation of HDFN when early in utero transfusion may be required and may have wider implications for the perinatal management in general.

Abstract
Management of maternal red cell alloimmunization has been revolutionized over the last 60 years. Advances in the prevention, screening, diagnosis, and treatment of alloimmune-induced fetal anemia make this condition an exemplar for contemporary practice in fetal therapy. Since survival is now an expectation, attention has turned to optimization of long-term outcomes following an alloimmunized pregnancy. In this review, the current management of red cell alloimmunization is described. Current research and future directions are discussed with particular emphasis on later life outcomes after alloimmune fetal anemia.

Abstract
Background Alloimmunization to red blood cells (RBCs) may result in fetal anemia prior to 20 weeks gestation. The question as to whether early commencement of antenatal treatment with high-dose intravenous immunoglobulins (IVIG) may prevent or at least delay the development of fetal anemia in the presence of alloantibodies to RBCs is highly relevant. Patients and Results Here we describe a patient with high-titer anti-K and two other severely affected pregnant women with a history of recurrent pregnancy loss due to high-titer anti-D or anti-D plus anti-C. Early commencement of treatment with IVIG (1 g/kg/week) resulted in prevention of intrauterine transfusion (IUT) in the former two cases, and in a significant delay of development of fetal anemia in the remaining case (26 weeks gestation). Conclusion Based on our findings and of previously published cases, early initiation of treatment of severely alloimmunized women with IVIG (1 g/kg/week) could potentially improve the outcome of fetuses at risk.

Abstract
BACKGROUND Intrauterine transfusion for severe alloimmunization in pregnancy performed <20 weeks' gestation is associated with a higher fetal death rate. Intravenous immunoglobulins may prevent hemolysis and could therefore be a noninvasive alternative for early transfusions. OBJECTIVE We evaluated whether maternal treatment with intravenous immunoglobulins defers the development of severe fetal anemia and its consequences in a retrospective cohort to which 12 fetal therapy centers contributed. STUDY DESIGN We included consecutive pregnancies of alloimmunized women with a history of severe hemolytic disease and by propensity analysis compared index pregnancies treated with intravenous immunoglobulins (n = 24) with pregnancies managed without intravenous immunoglobulins (n = 28). RESULTS In index pregnancies with intravenous immunoglobulin treatment, fetal anemia developed on average 15 days later compared to previous pregnancies (8% less often <20 weeks' gestation). In pregnancies without intravenous immunoglobulin treatment anemia developed 9 days earlier compared to previous pregnancies (10% more <20 weeks), an adjusted 4-day between-group difference in favor of the immunoglobulin group (95% confidence interval, -10 to +18; P = .564). In the subcohort in which immunoglobulin treatment was started <13 weeks, anemia developed 25 days later and 31% less <20 weeks' gestation (54% compared to 23%) than in the previous pregnancy. Fetal hydrops occurred in 4% of immunoglobulin-treated pregnancies and in 24% of those without intravenous immunoglobulin treatment (odds ratio, 0.03; 95% confidence interval, 0-0.5; P = .011). Exchange transfusions were given to 9% of neonates born from pregnancies with and in 37% without immunoglobulin treatment (odds ratio, 0.1; 95% confidence interval, 0-0.5; P = .009). CONCLUSION Intravenous immunoglobulin treatment in mothers pregnant with a fetus at risk for hemolytic disease seems to have a potential clinically relevant, beneficial effect on the course and severity of the disease. Confirmation in a multicenter randomized trial is needed.

Abstract
The main cause of fetal anemia is maternal red blood cell alloimmunization (AI). The search of maternal antibodies by indirect antiglobulin test allows screening for AI during pregnancy. In case of AI, fetal genotyping (for Rh-D, Rh-c, Rh-E and Kell), quantification (for anti-rhesus antibodies) and antibody titration, as well as ultrasound monitoring, are performed. This surveillance aims at screening for severe anemia before hydrops fetalis occurs. Management of severe anemia is based on intrauterine transfusion (IUT) or labor induction depending on gestational age. After intrauterine transfusion, follow-up will focus on detecting recurrence of anemia and detecting fetal brain injury. With IUT, survival of fetuses with alloimmunization is greater than 90% but 4.8% of children with at least one IUT have neurodevelopmental impairment.

Abstract
BACKGROUND Red blood cell alloimmunization in pregnancy can lead to fetal anaemia with potentially disastrous consequences. Traditional management involves the use of intrauterine transfusion, which is associated with significant procedure-related risks. An alternative treatment that has been trialled is the use of immunoglobulin administered intravenously to the mother. OBJECTIVES The objective of this review was to assess the efficacy and safety of the use of intravenous immunoglobulin antenatally to women with severe fetal red blood cell alloimmunization. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group trials register (19 December 2012), and reference lists of articles. SELECTION CRITERIA Randomized trials assessing the antenatal use of intravenous immunoglobulin administered at any dose, frequency or duration with a control group (using any other, or no treatment) in the management of fetal red blood cell alloimmunization. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the available evidence. MAIN RESULTS There are no included studies. AUTHORS' CONCLUSIONS No information is available from randomized trials to indicate whether the antenatal use of intravenous immunoglobulin is effective in the management of fetal red blood cell alloimmunization. Several case series suggest a beneficial role in delaying the onset of fetal anaemia requiring invasive intrauterine transfusion.

Abstract
BACKGROUND Despite limited data, international guidelines recommend the use of intravenous immunoglobulin (IVIg) in neonates with rhesus hemolytic disease. OBJECTIVE We tested whether prophylactic use of IVIg reduces the need for exchange transfusions in neonates with rhesus hemolytic disease. DESIGN AND SETTING We performed a randomized, double-blind, placebo-controlled trial in neonates with rhesus hemolytic disease. After stratification for treatment with intrauterine transfusion, neonates were randomly assigned for IVIg (0.75 g/kg) or placebo (5% glucose). The primary outcome was the rate of exchange transfusions. Secondary outcomes were duration of phototherapy, maximum bilirubin levels, and the need of top-up red-cell transfusions. RESULTS Eighty infants were included in the study, 53 of whom (66%) were treated with intrauterine transfusion(s). There was no difference in the rate of exchange transfusions between the IVIg and placebo groups (7 of 41 [17%] vs 6 of 39 [15%]; P = .99) and in the number of exchange transfusions per patient (median [range]: 0 [0-2] vs 0 [0-2]; P = .90) or in duration of phototherapy (4.7 [1.8] vs 5.1 [2.1] days; P = .34), maximum bilirubin levels (14.8 [4.7] vs 14.1 [4.9] mg/dL; P = .52), and proportion of neonates who required top-up red-cell transfusions (34 of 41 [83%] vs 34 of 39 [87%]; P = .76). CONCLUSIONS Prophylactic IVIg does not reduce the need for exchange transfusion or the rates of other adverse neonatal outcomes. Our findings do not support the use of IVIg in neonates with rhesus hemolytic disease.

Abstract
Phototherapy is the standard treatment in moderately severe hemolytic disease of newborn (HDN), whereas exchange transfusion (ET) is the second line in progressive cases. Intravenous immunoglobin (IVIG) has been suggested to decrease the need for ET. We aimed at assessing the efficacy of early two-dose regimens of IVIG to avoid unnecessary ET in severe Rh HDN. The study included 90 full-term neonates with Rh incompatibility unmodified by antenatal treatment and not eligible for early ET and which were randomly assigned into one of three groups: group (I), treated by conventional method; groups IIa and IIb received IVIG once at 12 h postnatal age if PT was indicated, in a dose of 0.5 and 1 g/kg, respectively. Analysis revealed 11 neonates (22%) in the conventional group and 2 (5%) in the intervention group who administered low-dose IVIG at 12 h, while none in group IIb required exchange transfusion (p = 0.03). Mean bilirubin levels were significantly lower during the first 96 h in the intervention group compared to the conventional group (p < 0.0001). Shorter duration of phototherapy (52.8 ± 12.39 h) and hospital stay (3.25 ± 0.71 days) in the IVIG group compared to conventional group (84 ± 12.12 h and 4.72 ± 0.78 days, p < 0.0001, respectively) were observed. We conclude that IVIG administration at 12 h was effective in the treatment of severe Rh HDN; the low-dose IVIG (0.5 g/kg) was as effective as high dose (1 g/kg) in reducing the duration of phototherapy and hospital stay, but less effective in avoiding exchange transfusion.

Abstract
The majority of neonates with Rh-isoimmunization develops late anemia between the second and the sixth week of life. We report the effectiveness of recombinant human erythropoietin (rHuEPO) in preventing late anemia in 25 intrauterine and nonintrauterine-transfused neonates. The neonates were treated from 11+/-4 days after birth to 26+/-14 days (400 U/kg/d of rHuEpo, administered subcutaneously). During rHuEpo therapy, vitamin E, calcium folinate, and iron maltose were administered intramuscularly on a daily basis. Hematocrit, platelet, and neutrophil counts did not differ significantly before and after 21-days therapy. However, average values for reticulocyte showed a significant increase. The hematocrit values in the non-intrauterine transfusion (IUT) group increased progressively from the beginning to the end of the treatment, whereas that in the IUT group remained stable. Reticulocyte count increased during treatment in both groups, but it was significantly elevated in the non-IUT group only. Moreover, we observed that only neonates transfused with IUTs needed transfusions before and after treatment. This study suggests the effectiveness of rHuEpo therapy in the treatment of neonates with Rh-isoimmunization and it highlights how IUTs decrease the neonatal response efficacy. Larger, better if multicentric, randomized controlled trial are needed to definitely state whether rHuEPO safely decreases the incidence of late onset anemia.
