Intrauterine management of fetal parvovirus B19 infection. (1/64)

OBJECTIVES: The aim of our study was to determine the outcome of pregnancies after intrauterine management of fetal parvovirus B19 infection. DESIGN: Retrospective study. SUBJECTS: A total of 37 cases of maternofetal parvovirus B19 infection, 35 of which were associated with hydrops fetalis, were referred to our tertiary level center between 1989 and 1996. With regard to fetal hydrops, no apparent cause other than parvovirus B19 infection was found in any patient. METHODS: In all patients, cordocentesis was performed to assess the degree of fetal anemia. When anemia was present, cordocentesis was followed by intrauterine transfusion with packed red cells into the umbilical vein. Further management depended on the degree of fetal anemia and gestational age and included follow-up fetal blood sampling/transfusion as well as ultrasound examinations as deemed appropriate. RESULTS: Packed red cell transfusion was performed in 30 patients with significant fetal anemia (Z-score 1.6-7.8 below the mean for gestational age). The fetal hemoglobin values ranged from 2.1 to 9.6 g/dl. Serum levels of platelets in the transfusion group were 9-228 x 10(9)/l with Z-scores in the range of < 1 to 3.8 below the mean. During treatment and follow-up, there were five intrauterine deaths (13.5%), one neonatal death (2.7%) and 31 live births (83.8%). CONCLUSIONS: Fetal parvovirus infection can lead to marked anemia and hydrops formation. Cordocentesis allows precise assessment of fetal anemia which can then be corrected by intravenous transfusion. Under this regimen, the outcome proved favorable in the majority of fetuses, even those that were severely anemic.  (+info)

OBJECTIVES: Immune hemolytic anemia in the fetus may cause cardiac decompensation and intrauterine death. Postnatally, norepinephrine (noradrenaline) is released in chronic heart failure, and may lead to myocardial hypertrophy. The aim of this study was to determine fetal cardiac changes associated with immune hemolytic anemia by means of echocardiography, and to relate them to fetal hemoglobin and norepinephrine levels. DESIGN: Thirty anemic fetuses underwent a total of 76 umbilical venous transfusions. Before the procedure, fetal echocardiography was performed, and end-diastolic myocardial wall thicknesses and ventricular dimensions together with Doppler flow patterns at the atrioventricular and semilunar valves were measured. Fetal hemoglobin, epinephrine and norepinephrine concentrations were determined before the transfusion. Statistical analysis of this prospective study comprised descriptive statistics including linear regression and correlation analyses. Two samples of measurements were compared by the Mann-Whitney U test. RESULTS: The mean hemoglobin concentration before the first transfusion was 6.9 g% at a mean gestational age of 26.8 weeks. Norepinephrine values were elevated in comparison to a reference range, and were higher than epinephrine values. The most striking echocardiographic finding was myocardial hypertrophy of all ventricular walls. Mean blood flow velocities were increased; at the left ventricle, they were negatively related to the hemoglobin concentrations, and positively to the norepinephrine values. CONCLUSIONS: Fetal myocardial hypertrophy in anemia may be the result of an augmented cardiac workload, indicated by the increased left ventricular mean velocities. This reaction reflects the redistribution of blood flow that may depend on hemoglobin and norepinephrine concentrations.  (+info)

Perinatal management of fetal hemolytic disease due to Rh incompatibility combined with fetal alloimmune thrombocytopenia due to HPA-5b incompatibility. (3/64)

We report out experience in the perinatal management of a complex case of fetal hemolytic disease primarily due to Rhesus incompatibility combined with fetal alloimmune thrombocytopenia. The lowest fetal hemoglobin and platelet levels were 2.6 g/dl and 13,000/microliter, respectively. Intrauterine treatment consisted of six transfusions of packed red cells into the umbilical vein and one transfusion of platelets. The neonate required four transfusions of packed red cells to correct her hyporegenerative erythropoiesis. Postnatal management also included one platelet transfusion, intravenous immunoglobulins and erythropoietin. Although some degree of fetal thrombocytopenia may invariably be found in fetal red cell incompatibility, other rare causes need to be excluded.  (+info)

Pathophysiology and treatment of fetal anemia due to placental chorioangioma. (4/64)

Placental chorioangiomas occur in 1% of pregnancies. Large chorioangiomas may cause serious complications such as fetal anemia, hydrops and fetal death. In this case report, a pregnancy complicated by a large placental chorioangioma is described. Severe fetal anemia without the occurrence of hydrops fetalis was suspected using ultrasound and Doppler examinations. Successful intrauterine blood transfusion was performed, with an unusually large amount of blood needed to obtain an adequate rise in fetal hematocrit. Two weeks later, at 32 weeks, the infant was born in good condition. In pregnancies with large chorioangiomas, we advise regular ultrasound and Doppler examinations, with the aim of detecting fetal anemia before hydrops develops. When anemia is suspected, fetal blood sampling is indicated and intrauterine transfusion therapy may be beneficial to preserve fetal health until maturity is reached.  (+info)

Survival of donor cells 25 years after intrauterine transfusion. (5/64)

Persistence of donor leukocytes in the circulation of recipients of intrauterine transfusion (IUT) has been observed up to 5 years after birth. The aim of this study was to determine whether transfusions with nonirradiated, nonleukocyte-depleted donor blood during the fetal period resulted in long-term immunomodulation of the recipient. Twenty-four surviving IUT recipients between 1966 and 1976 were tested for autoimmune disease and autoantibodies at follow-up. Ten had sex-mismatched donors and were therefore informative for chimerism studies using fluorescence in situ hybridization (FISH). Seven female recipients could be tested for chimerism using a Y- chromosome-specific polymerase chain reaction (PCR) because they received at least 1 IUT from a male donor. Nine recipients could be studied for cytotoxic T-lymphocyte precursor (CTLp) and helper T-lymphocyte precursor (HTLp) frequencies because the original donors were available for testing. All surviving IUT recipients were in good health at the time of the examination, and routine laboratory testing revealed no abnormalities. None of the IUT recipients were chimeric as determined by FISH analysis, but Y-chromosome-specific sequences were detected by PCR in 6 of the 7 women. However, the CTLp and HTLp frequencies of the IUT recipients against the donors were comparable to those of the controls. The current study provides evidence that IUT can result in the persistence of donor cells in the recipient for a period longer than 20 years but that it is not associated with immunotolerance or with signs of chronic antigenic stimulation.

Dual natriuretic peptide response to volume load in the fetal circulation. (6/64)

OBJECTIVE: To measure atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in control fetuses and fetuses with Rhesus isoimmunisation before and after intravascular transfusion. The current study was designed to investigate the response of ANP and BNP to cardiac short-term and long-term volume load in the human fetus. METHODS: Fetal blood samples were collected from 18 human fetuses (nine controls, nine anemic fetuses with Rhesus isoimmunisation before and after intravascular transfusion). Fetal ANP and BNP concentrations were measured and compared to maternal plasma levels. RESULTS: Both ANP and BNP were significantly higher in fetal blood compared to the mothers. Fetuses with Rhesus isoimmunisation, characterized by long-term cardiac overload, showed significantly elevated ANP but not BNP concentration compared to the fetal controls (ANP: 80.8+/-16.6 vs. 31.6+/-7.7 pg/ml, P<0.05). However, short-term volume load due to intravascular transfusion leads to a significant increase in the fetal BNP- but not ANP-plasma level (BNP: 112.9+/-14.1 vs. 64.8+/-6.6 pg/ml, P<0.05). CONCLUSION: ANP and BNP respond differently to cardiac short- and long-term volume load in the fetal circulation. Therefore, the data suggest that in the fetus, similar to adults, ANP and BNP constitute a dual natriuretic peptide system responsive to changes in cardiac filling pressure.  (+info)

Hydrops fetalis-associated congenital dyserythropoietic anemia treated with intrauterine transfusions and bone marrow transplantation. (7/64)

Hydrops fetalis is rarely caused by congenital dyserythropoietic anemia (CDA). We report a patient with hydrops fetalis as a result of severe anemia. This patient needed intrauterine transfusions from 21 weeks of gestation until birth. The hematologic study showed an atypical CDA (hydrops fetalis-associated CDA) characterized by features resembling CDA type II, but negative acidified serum lysis test (HEMPAS negative). The patient was regularly transfused for a year, after which an allogeneic bone marrow transplantation (BMT) from an HLA-identical sibling was successfully carried out. His actual hemoglobin is 127 g/L, and he has not received transfusions for more than a year. In conclusion, intrauterine transfusions and BMT could cure an otherwise lethal atypical CDA.  (+info)

Management of single fetal death in twin-to-twin transfusion syndrome: a role for fetal blood sampling. (8/64)

OBJECTIVE: Intrauterine death of one twin in monochorionic pregnancies is associated with an increased mortality and morbidity of the cotwin. This is likely to occur as a consequence of acute hemodynamic changes due to feto-fetal hemorrhage at the time of death of the cotwin. We assessed the role of fetal blood sampling and intrauterine transfusion to rescue the survivor. MATERIALS AND METHODS: We managed 12 cases of single intrauterine death at between 17 and 26 weeks' gestation in monochorionic twins complicated by twin-to-twin transfusion syndrome (TTTS). All these cases had been treated either by laser therapy or by serial amniodrainage. When the demise of one twin occurred, ultrasound-guided fetal blood sampling was performed in the surviving twin using a 20-gauge needle within 24 h of death. Intrauterine transfusion was performed at the same time in cases where the survivor was anemic. All survivors were assessed in the neonatal period and at 1 year of age. RESULTS: Six of the 12 surviving fetuses were found to be anemic and underwent intrauterine transfusion. All fetuses survived the procedure. Four of these fetuses had normal neurological development at 1 year of age. Periventricular leukomalacia developed in one case and the patient underwent termination of pregnancy at 34 weeks. In one case delivery occurred at 34 weeks' gestation and the baby developed periventricular leukomalacia at 1 month of age. In all six non-anemic fetuses pediatric examination was normal at birth and at 1 year of age. CONCLUSION: Intrauterine death of one monochorionic twin in TTTS puts the survivor at high risk of intrauterine death or of developing ischemic/hypoxic lesions. Our results suggest that fetal blood sampling is a useful diagnostic tool to identify those fetuses that are not anemic and hence unlikely to be at risk of developing a cerebral lesion.  (+info)

Intrauterine transfusion is performed in the hospital, usually on an outpatient basis. The mother is given antibiotics, local anesthesia and IV sedation, which also sedates the fetus. The fetus may be given additional medication to stop movement. Using ultrasound to determine the position of the fetus and placenta, the surgeon inserts a needle into the mothers abdomen and then into the umbilical cord vein or the fetus abdomen. Red blood cells that are compatible with the fetus blood type are passed through the needle into the fetus. The mother will probably not have to spend the night in the hospital, but the doctor may prescribe antibiotics and medication to prevent labor. Fetal transfusions may need to be repeated every few weeks until the fetus is ready to be born.. The chance of problems is rare, but there are risks in every procedure. In intrauterine transfusion, these may include:. ...

Rh incompatibility occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus, leading to the mother s development of Rh antibodies. These antibodies have the potential to cross the placenta and attach to fetal red blood cells, resulting in hemolysis, or destruction of the fetus s red blood cells. This causes the fetus to become anemic, which can lead to hemolytic disease of the newborn. In severe cases, an intrauterine blood transfusion for the fetus may be required to correct the anemia..

A number of attempts have also been undertaken to perform PGD for Rhesus disease, which, however, has not yet resulted in a clinical pregnancy.34 Both of these conditions are quite prevalent, taking into consideration the approximately 15% frequency for RhD and 9% for KEL antigen, presenting the risk for alloimmunization that may lead to HDN in some of the at-risk couples. Therefore, PGD may be a useful option for these couples to avoid the establishment of the RhD or K1 pregnancy in the sensitized mothers.. Although the at-risk pregnancies detected by prenatal diagnosis may be treated by an intrauterine transfusion, the potential complication for the fetus cannot be completely excluded even after this procedure. Pregnancy termination in such cases will also be unacceptable, because the antibodies to K1, for example, are developed only in 5% of persons obtaining incompatible blood. However, some of the at-risk couples have had such unfortunate experience with HDN, resulting in neonatal death as ...
were observed. Fetal heart was enlarged, with reportedly decreased contractibility. The Doppler parameters were abnormal: the peak systolic velocity in median cerebral artery (MCA PSV) was increased (84 cm/s, 3 MoM), and absent end diastolic flow (AEDF) was reported in the umbilical artery. Ultrasound examination indicated severe fetal anemia and heart failure. Umbilical vein puncture was performed and the fetal blood count was determined (RBC 0.01 × 106/μl, Ht 0.1%, PLT 67 × 103/μl, WBC 2.1 × 103/μl, indeterminable hemoglobin level). Packed red blood cells (0 Rh-, 30 ml) were immediately transfused to the fetus. Altogether, seven intrauterine transfusions were performed. Fetal hydrops disappeared gradually during the next few weeks. The male neonate (1860 g, 45 cm, Apgar score 3-4) was delivered after the last transfusion at 34th week of gestation due of intrauterine asphyxia. The infant was discharged after 21 days, in good condition, on breastfeeding. There was one 10 mm focus of ...
The use of maternal premedication for IUT varies by center and may include use of local anesthetics, indomethacin/pethidine/promethazine, or spinal epidural analgesia. The prophylactic use of antibiotics or corticosteroids are sometimes used but their necessity is not well-established 18, 19. Premedication for the fetus is necessary in most cases including atracurium or vecuronium 6, 21 for fetal paralysis. Some practitioners recommend fentanyl for fetal pain 20 though it is not universally used 22. Click here for more detailed information about medications during IUTs.. Intrauterine transfusion should be guided by continuous ultrasound and staffed, at minimum, by an experienced maternal fetal medicine (MFM) specialist/perinatologist, seasoned ultrasonographer and one or more operating nurses. Inclusion of a neonatologist and/or additional MFM/perinatologist and support staff is not unwarranted. Transfusion volume can be calculated using a simplified formula by Giannina et al29 to attain 45% ...

An intrauterine transfusion provides blood to an Rh-positive fetus when fetal red blood cells are being destroyed by Rh antibodies.. A blood transfusion is given to replace fetal red blood cells that are being destroyed by the Rh-sensitized mothers immune system. This treatment is meant to keep the fetus healthy until he or she is mature enough to be delivered.. Transfusions can be given through the fetal abdomen or, more commonly, by delivering the blood into the umbilical vein or artery. Umbilical cord vessel transfusion is the preferred method, because it permits better absorption of blood and has a higher survival rate than does transfusion through the abdomen.footnote 1. An intrauterine fetal blood transfusion is done in the hospital. The mother may have to stay overnight after the procedure.. ...
We recruited women with singleton pregnancies undergoing clinically indicated serial intrauterine transfusions between 20 and 35 weeks for alloimmune fetal anemia or thrombocytopenia in two tertiary referral fetal medicine centers (London and Glasgow) between November 1996 and July 1999. Gestational age was based on certain menstrual dates or ultrasound 18 weeks or less. Fetal growth and well-being were assessed by ultrasound. Inclusion criteria were size appropriate for gestational age (abdominal circumference ≥ fifth centile), absence of structural anomalies, no evidence of hydrops, and positive end-diastolic frequencies in the umbilical artery Doppler waveform. Fetuses with hypoxemia (oxygen partial pressure , −2 z scores), aneuploidy, or severe anemia (hemoglobin , 5 g/dl) were excluded, as were procedures that were difficult (time to access , 10 min) or complicated by significant intraprocedural bradycardia (fetal heart rate , 80 beats/min lasting , 30s). All women gave written informed ...

Intravenous transfusion of concanavalin A-activated splenic cells from acutely diabetic BB or diabetic BB/hooded hybrid donor rats into 6- to 36-h-old neonate recipients of diabetes-prone and -resistant rat lines induced insulitis and in some severe diabetes. These effects were observed 10-20 days after the injection of the blasts. Focal lesions of insulitis were absent in neonates killed 1 and 3 days after the blast injection but were observed in neonates killed on the 5th and 8th day. As determined by autoradiography after the injection of [3H]thymidine-labeled blasts, numerous blast cells migrated and settled in various immature lymph nodes and in the spleen within 24 h after injection. Focal mononuclear infiltrations in the islets containing labeled and unlabeled cells were again observed on the 5th and 8th day but not on the 1st and 3rd day after injection. These experiments indicate that target-specific blasts undergo a short phase of proliferation and maturation in lymphoid organs of the

BACKGROUND AND OBJECTIVES: Serological evaluation of maternal sera for platelet antibodies in suspected fetal/neonatal alloimmune thrombocytopenia (FNAITP) discloses in only approximately 30% of individuals a platelet-specific antibody. Transfusion-induced alloimmunization against human platelet antigen-15 (HPA-15) has been reported to be about as common as against HPA-5, the second most common platelet antibody. Thus, anti-HPA-15 may also contribute significantly to yet-unclear cases of FNAITP.. MATERIALS AND METHODS: In this retrospective analysis, we provide data on maternal platelet antibodies from 309 mothers who delivered an offspring with suspected FNAITP.. RESULTS: Genotyping maternal and paternal samples (together n = 573) revealed a gene frequency of 0.496 for HPA-15a and a gene frequency of 0.504 for HPA-15b. HPA-15 antibodies were detected in 2% of all samples. Anti-HPA-15a and -15b were detected in two and three samples, respectively. One serum reacted equally with HPA-15a and -15b ...
Objectives: 1) To determine risk factors for fetomaternal hemorrhage. 2) To identify a cost-effective method to detect fetomaternal hemorrhage prior to significant fetal anemia.. Significance/Background: Fetomaternal hemorrhage (FMH) is a condition in which occurs when the placenta transfers blood from the fetus to the mother. Normally, nutrition and gasses pass from mother to baby through the placenta and only waste products pass from baby to mother through the placenta. Whole blood cells do not normally cross the placenta in significant amounts. Mild FMH, where a small amount of whole blood passes from fetus to mother but does not hurt the mother or baby, occurs in about 75% of pregnancies. A pregnant woman does not know this occurs. It is only discovered if a special blood test that is labor-intensive to perform and difficult to interpret called the Kleihauer-Betke acid elution test is done. As mild FMH hurts no one, this test is not part of routine care. In most cases, testing is done only ...

I have anemia and needed a blood transfusion and attempted my first transfusion last week. After about a tablespoon of blood went into my IV, my vision grayed out and I dont remember what happened next. I was told I had chills, diaphoresis, decreased level of consciousness, eyes rolling back in head and woke up so to speak, vomiting. What happened to me? They said I had no fever but had a severe transfusion reaction. I received Benadryl and Solu-Medrol and a bag of fluid after that. They had stopped the blood when I came to and said my blood pressure had dropped to 70/40 and my pulse had dropped. My family doctor was called and diagnosed it as a vasovagal reaction. Can a severe blood transfusion reaction be called a vasovagal reaction? They said there was no hemolyzation of the blood. What exactly happened? How often does this happen? They gave me another unit with the premedication and filter, and it seemed to work okay that time. What do I need to understand about what happened ...

TY - JOUR. T1 - Fetal platelet counts correlate with the severity of the anemia in red-cell alloimmunization. AU - Saade, George. AU - Moise, K. J.. AU - Copel, J. A.. AU - Belfort, M. A.. AU - Carpenter, R. J.. PY - 1993. Y1 - 1993. N2 - Objective: To determine whether fetal anemia secondary to maternal red-cell alloimmunization is associated with thrombocytopenia. Methods: The records of 78 patients undergoing intrauterine transfusion for red-cell alloimmunization were reviewed. Pre-transfusion fetal platelet counts were compared between hydropic and nonhydropic fetuses. A regression analysis was performed between the fetal platelet counts and the fetal bilirubin levels, hematocrits, and reticulocyte counts taken at the initial transfusion. The hematocrits, reticulocyte counts, and bilirubin levels were adjusted for gestational age by calculating the number of standard deviations (SDs) from the mean for that age or the multiples of the mean (MOM). Student t test, Pearson coefficient, and ...
Diamond Blackfan anemia (DBA) is a lineage-selective inherited bone marrow failure syndrome characterized primarily by anemia and physical malformations. Recent advances in identifying the genetic abnormalities underlying DBA have demonstrated involvement of genes encoding both large (RPL) and small (RPS) ribosomal subunit proteins, including mutations of RPL5, RPL11, RPL35A, RPS7, RPS10, RPS17, RPS19, RPS24, and RPS26 in 50% to 60% of affected patients. Despite significant progress, identification of gene abnormalities in the remaining patients remains an important question since present data suggest that mutations in other members of the ribosomal protein gene complement do not explain those cases without an identified genetic lesion in these genes. Genetic studies have also raised new questions with the recognition of substantial variability in the manifestations of DBA, ranging from ribosomal protein mutations in otherwise asymptomatic individuals to those with classic severe red blood cell ...
Rh incompatibility is caused by destruction of fetal erythrocytes from transplacental passage of maternally derived IgG antibodies. IgG antibodies are produced by the maternal immune system, usually against the rhesus D (RhD) antigen. These antibodies can freely cross the placenta, binding to and destroying RBCs. More than 50 known RBC antibodies potentially cause Rh incompatibility. The consequence is progressive fetal anaemia, which may ultimately lead to hydrops fetalis (collection of fluid in serous compartments) and death. [1] Hadley AG.
