Serum malondialdehyde concentration in babies with hyperbilirubinaemia. (1/148)

AIM: To determine lipid peroxide concentrations in the first 10 days of life. METHODS: Malondialdehyde concentrations were investigated in neonates with or without hyperbilirubinaemia during the first 10 days of life. RESULTS: Serum malondialdehyde concentrations were higher in infants with hyperbilirubinaemia than in controls. A positive correlation was found between malondialdehyde and bilirubin concentrations in the study group. When the study group was categorised according to the presence of haemolysis, a significant correlation was found between malondialdehyde and bilirubin concentrations in those infants with hyperbilirubinaemia due to haemolysis. There was no such correlation in those without haemolysis. CONCLUSION: Exchange transfusion rapidly produces variable changes in pro-oxidant and antioxidant plasma concentrations in neonates, which may be responsible for free radical metabolism. The fall in malondialdehyde concentration is probably directly related to its exogenous removal by exchange transfusion.  (+info)

Perinatal management of fetal hemolytic disease due to Rh incompatibility combined with fetal alloimmune thrombocytopenia due to HPA-5b incompatibility. (2/148)

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)

A likelihood-based method of identifying contaminated lots of blood product. (3/148)

BACKGROUND: In 1994 a small cluster of hepatitis-C cases in Rhesus-negative women in Ireland prompted a nationwide screening programme for hepatitis-C antibodies in all anti-D recipients. A total of 55 386 women presented for screening and a history of exposure to anti-D was sought from all those testing positive and a sample of those testing negative. The resulting data comprised 620 antibody-positive and 1708 antibody-negative women with known exposure history, and interest was focused on using these data to estimate the infectivity of anti-D in the period 1970-1993. METHODS: Any exposure to anti-D provides an opportunity for infection, but the infection status at each exposure time is not observed. Instead, the available data from antibody testing only indicate whether at least one of the exposures resulted in infection. Using a simple Bernoulli model to describe the risk of infection in each year, the absence of information regarding which exposure(s) led to infection fits neatly into the framework of 'incomplete data'. Hence the expectation-maximization (EM) algorithm provides estimates of the infectiousness of anti-D in each of the 24 years studied. RESULTS: The analysis highlighted the 1977 anti-D as a source of infection, a fact which was confirmed by laboratory investigation. Other suspect batches were also identified, helping to direct the efforts of laboratory investigators. CONCLUSIONS: We have presented a method to estimate the risk of infection at each exposure time from multiple exposure data. The method can also be used to estimate transmission rates and the risk associated with different sources of infection in a range of infectious disease applications.  (+info)

Noninvasive diagnosis by Doppler ultrasonography of fetal anemia due to maternal red-cell alloimmunization. Collaborative Group for Doppler Assessment of the Blood Velocity in Anemic Fetuses. (4/148)

BACKGROUND: Invasive techniques such as amniocentesis and cordocentesis are used for diagnosis and treatment in fetuses at risk for anemia due to maternal red-cell alloimmunization. The purpose of our study was to determine the value of noninvasive measurements of the velocity of blood flow in the fetal middle cerebral artery for the diagnosis of fetal anemia. METHODS: We measured the hemoglobin concentration in blood obtained by cordocentesis and also the peak velocity of systolic blood flow in the middle cerebral artery in 111 fetuses at risk for anemia due to maternal red-cell alloimmunization. Peak systolic velocity was measured by Doppler velocimetry. To identify the fetuses with anemia, the hemoglobin values of those at risk were compared with the values in 265 normal fetuses. RESULTS: Fetal hemoglobin concentrations increased with increasing gestational age in the 265 normal fetuses. Among the 111 fetuses at risk for anemia, 41 fetuses did not have anemia; 35 had mild anemia; 4 had moderate anemia; and 31, including 12 with hydrops, had severe anemia. The sensitivity of an increased peak velocity of systolic blood flow in the middle cerebral artery for the prediction of moderate or severe anemia was 100 percent either in the presence or in the absence of hydrops (95 percent confidence interval, 86 to 100 percent for the 23 fetuses without hydrops), with a false positive rate of 12 percent. CONCLUSIONS: In fetuses without hydrops that are at risk because of maternal red-cell alloimmunization, moderate and severe anemia can be detected noninvasively by Doppler ultrasonography on the basis of an increase in the peak velocity of systolic blood flow in the middle cerebral artery.  (+info)

Hemolytic disease of the newborn due to anti S antibodies. (5/148)

We report a case of hemolytic disease in a newborn due to anti S antibodies. Baby R was born at term to an O+ mother whose antibody screen was positive for phenotype big S. Cord blood eluate revealed anti-S RBC; antigen: RBC typing for S- was positive. Physical examination of baby was unremarkable. The infant's HCT was 44.2 at 6 hours of age. At 48 hours, the HCT decreased to 33.5, bilirubin peaked to 5.4, retic had peaked to 6.8. By seven days, all these values reverted to the normal, and baby has remained asymptomatic.  (+info)

Middle cerebral artery peak systolic velocity in the prediction of fetal anemia. (6/148)

OBJECTIVE: The fetal middle cerebral artery peak systolic velocity (MCA PSV) has been suggested as a potential test to predict the fetal hematocrit level. We tested the hypothesis that a low fetal hematocrit is associated with an increase in MCA PSV in a prospective study of normal and alloimmunized pregnancies. METHODS: Fetal hematocrit and MCA PSV were obtained in 26 alloimmunized fetuses, immediately before their first fetal blood transfusions between 15 and 35 weeks. Results were compared with the MCA PSVs from 170 control fetuses not at risk of alloimmune anemia between 13 and 37 weeks. RESULTS: In control fetuses, PSV varied with gestation (PSV = 0.56 - 0.032 GA + 0.00086 GA2, where GA is gestational age; R2 = 0.41). The correlation between PSV and hematocrit Z scores (Pearson correlation coefficient r = -0.69) was highly significant (P = 0.0001). Using a PSV > 1 SD, the sensitivity of the test in predicting a fetal hematocrit < 2 SD below the mean was only 64% but the specificity was 100%. However, the sensitivity of the test in predicting a fetal hematocrit < 3 SD and < 4 SD rose to 73% and 83%, while the specificity was still good (93% and 80% respectively). CONCLUSIONS: MCA PSV and fetal hematocrit are highly significantly correlated. The sensitivity of the test was good and the high positive predictive value indicates that the presence of a raised PSV (defined as > 1 SD) is a strong indicator of fetal anemia. In conclusion, MCA PSV is a useful test in clinical practice for the detection of fetal anemia.  (+info)

Early neonatal hypocalcaemia. (7/148)

In our hospital early neonatal hypocalcaemia is now the major cause of low serum calcium in the neonatal period. Over a 2-year period, only 2 cases of hypocalcaemic convulsions were seen in a total of 8700 deliveries, though 51 infants had early neonatal hypocalcaemia. All sick low birth-weight infants should have daily serum calcium estimations carried out. Calcium supplements should be considered if symptoms of hypocalcaemia are present.  (+info)

Identification of alloreactive T-cell epitopes on the Rhesus D protein. (8/148)

Although considerable effort has been devoted to characterizing alloantibodies specific for the Rhesus D (RhD) blood group antigen, virtually nothing is known about the helper response that drives their production. Therefore, the aim of this study was to map alloreactive T-cell epitopes on the RhD protein. Peripheral blood mononuclear cells (PBMCs) were obtained from 22 RhD-negative volunteers in whom anti-D alloantibodies had developed after deliberate immunization or RhD-incompatible pregnancy. The PBMCs were stimulated with a panel of up to 68 overlapping synthetic 15-mer peptides spanning the complete sequence of the RhD protein. One or more peptides elicited proliferative responses by PBMCs from all 22 of the alloimmune volunteers but from only 2 of 8 alloantibody-negative control donors. Proliferation of PBMCs from the alloimmune donors was mediated by major histocompatibility complex class II-restricted T cells expressing the CD45RO marker of previous activation or memory. The number of peptides that induced proliferative responses was unrelated to either the frequency of, or time since, exposure to RhD-positive red blood cells, but it correlated strongly (R(s) = 0.75; P <.003) with the level of anti-D antibodies in deliberately immunized donors. The patterns of stimulatory peptides varied among alloimmune volunteers, but particular sequences were commonly recognized, with 4 peptides each eliciting a response in more than 50% of these donors. Identification of such peptides containing dominant alloreactive helper epitopes is the first step in the development of improved or new approaches to preventing hemolytic disease of the newborn that are based on modulating the T-cell response to the RhD protein.  (+info)

Rh sensitization can occur when a person with Rh-negative blood is exposed to Rh-positive blood. Most women who become sensitized do so during childbirth, when their blood mixes with the Rh-positive blood of their fetus. After being exposed, a mothers immune system produces antibodies against Rh-positive red blood cells.. The minimum amount of blood mixing that causes sensitization is not known. Fortunately, Rh sensitization can almost always be prevented with the Rh immune globulin injection.. When an Rh-negative persons immune system is first exposed to Rh-positive blood, it takes several weeks to develop immunoglobulin M, or IgM, antibodies. IgM antibodies are too large to cross the placenta. So the Rh-positive fetus that first triggers maternal sensitization is usually not harmed.. A previously Rh-sensitized immune system rapidly reacts to Rh-positive blood, as during a second pregnancy with an Rh-positive fetus. Usually within hours of Rh-positive blood exposure, smaller immunoglobulin G, ...

A rhesus D positive baby in a rhesus D negative mother can cause her circulation to produce anti-D IgG antibodies (isoimmunisation) if foetal cells leak into the maternal circulation which may happen at delivery and in trauma even mild in severity. Tests for D antibodies are done in all Rh-ve mothers at booking, 28 and 34 weeks gestation. Anti-D immunoglobulin is routinely given antenatally at 28 weeks and 34 weeks. Rhesus haemolytic disease is a disease that can vary in severity from mild anaemia to hydrops fetalis or still birth. The Rhesus D antigen has been found to be well established in a 6week old foetus [Murphy] and although the foetus at that age is protected to a large extent by the pelvis the chance of foetal blood leaking into the maternal circulation in the event of an abdominal trauma is highly likely and may infact occur before the standard administration at 28 weeks. Once antibody formation has occurred the administration of anti-D is ineffective so any delay in administering it ...
Rh blood type is especially important for pregnant women. A potential problem arises when a woman who has Rh-negative blood becomes pregnant with a baby (fetus) that has Rh-positive blood. This is called Rh incompatibility. If the blood of an Rh-positive baby mixes with the blood of an Rh-negative woman during pregnancy or delivery, the mothers immune system produces antibodies. This antibody response is called Rh sensitization and, depending on when it occurs, can destroy the babys red blood cells.. Rh sensitization does not usually affect the health of the baby during the pregnancy in which the sensitization occurs. However, the baby of a future pregnancy is more likely to be affected if the babys blood type is Rh-positive. Once sensitization has occurred, the baby can develop mild to severe problems (called Rh disease, hemolytic disease of the newborn). If untreated, complications from sensitization can, in rare cases, lead to the death of an Rh-positive baby.. An Rh test is done in early ...

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.

Rh negative women who deliver an Rh positive baby are at risk of developing anti-Rh antibodies.1 Rh positive babies born of these mothers will develop Rh haemolytic disease. This is a severe condition responsible for death in utero or in the neonatal period or severe jaundice with ensuing brain damage. The natural history of the disease has not been described in recent literature. Walker,1 in 1971, reviewed a series of cases from his community. It was found that 14% of affected pregnancies resulted in stillbirths. Of the survivors, 30% had severe disease almost certainly fatal without treatment, while an additional 30% had moderate disease which would manifest as severe hyperbilirubinaemia that untreated may result in brain damage and/or death. Forty per cent of cases would require no treatment. Therefore, it can be estimated that approximately 50% of children with untreated haemolytic disease of the newborn (HDN) will die of the disease or develop brain damage. Similar observations were made in ...

Clinically severe jaundice due to ABO incompatibility can occur when infants with blood type A or B are born to mothers with type O blood. An estimated 20 percent of pregnancies are ABO incompatible, but only a very small proportion of blood type A or B babies born to O type mothers develop overt ABO hemolytic disease. Despite the relative rarity of ABO hemolytic disease, it is common practice among pediatricians and family practice physicians to perform routine blood typing and antibody screening on all newborns born to type O mothers.. A very accurate and reliable laboratory measure of red blood cell destruction is the plasma carboxyhemoglobin level (COHb). COHb levels can be determined using a minute amount of blood, obtained at the same time the newborns heel is pierced to obtain blood for the mandatory newborn screen (performed on all newborns prior to discharge) in order to avoid an additional invasive procedure.. Our hope is to determine whether routine blood typing and anti-globulin ...
Rh is an antigen. The full name for this antigen is Rhesus factor.. If a pregnant woman with Rh-negative blood is pregnant with a baby (fetus) with Rh-positive blood, Rh sensitization may occur. The baby may have Rh-positive blood if the father has Rh-positive blood. Rh sensitization happens when the babys blood mixes with the mothers blood during pregnancy or delivery. This causes the mothers immune system to make antibodies against the babys red blood cells in future pregnancies. This antibody response is called Rh sensitization and, depending on when it happens, can destroy the red blood cells of the baby before or after it is born. If sensitization happens, a fetus or newborn can develop mild to severe problems (called Rh disease or erythroblastosis fetalis). In rare cases, if Rh disease is not treated, the fetus or newborn may die.. A woman with Rh-negative blood can get a shot of Rh immunoglobulin (such as RhoGAM) that almost always stops sensitization from occurring. Problems from Rh ...
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:. ...
BAPTISTA-GONZALEZ, Héctor Alfredo; ROSENFELD-MANN, Fany y LEISS-MARQUEZ, Teresita. Prevention of maternal RhD isoimmunization with anti-D gamma globulin. Salud pública Méx [online]. 2001, vol.43, n.1, pp.52-58. ISSN 0036-3634.. OBJECTIVE: To report our experience in preventing RhD maternal isoimmunization by using anti-D gamma globulin among Rh-negative women. MATERIAL AND METHODS: Between 1982 and 1995, immunologic and hematologic data were collected from all Rh-negative women seen at Mexicos National Perinatology Institute. Women at risk of Rh isoimmunization were given a prophylactic dose of 150 µg of anti-D gamma globulin. RESULTS: A total of 4 857 Rh-negative women were seen during the study period (4.85% of the total population of women seen at the Institute), 629 (13.0%) of whom developed RhD isoimmunization; 542 (86.2%) of these women were already isoimmunized when first seen at our Institute. Twenty-two women (3.5%) developed isoimmunization even after receiving a proper dose of ...
A 36-week 3550 g neonate is admitted to the intensive care unit and commenced on intensive phototherapy for known Rhesus haemolytic disease. In spite of intensive phototherapy, the bilirubin level approaches the exchange transfusion threshold by hour 16 of life. The specialist registrar orders a crossmatch of blood and arranges for central line insertion in preparation for an exchange transfusion. The new registrar queries why intravenous immunoglobulin is not being used first in an attempt to avoid exchange transfusion. ...
The laboratory and clinical management of alloimmunized in pregnancy has been investigated according to a protocol currently in use in Örebro region. A 12 year epidemiological study showed the prevalence of alloimmunization to be 0.57% in this Swedish populationwith a 0.24% incidence of clinically significant antibodies that can induce haemolytic disease of the newborn (HDN). Rh antibodies, predominantly anti-D, are still the causes of most cases of severe HDN in which 45/47 babies required exchange transfusion. During the studyperiod, 14 mothers were successfully treated with plasma exchange during pregnancy owing to high anti-D antibody concentrations. Only two other blood group syswms, Kell and Duffy, besides Rh affected newborns to alloimmunized mothers to such a grade that exchange transfusion of the newborns was necessary. All generally accepted for the fetus clinically nonsignificant antibodies were also followed and shown not to cause HDN. In 3 instances, anti-D was detected in partial ...
In 79 pregnancies with erythroblastosis fetalis, fetal blood was sampled to assess the level of anaemia. Significant correlations were found between the haemoglobin concentration and umbilical artery pH, bicarbonate concentration and base excess. Compensatory mechanisms help to maintain oxygen supply in anaemia but their failure is associated with hydrops fetalis.
The Rh-antigens classify people into Rh-positive or Rh-negative groups, and each of us acquires a pair of Rh-controlling genes from our parents (one from father and one from mother). The Rh-negative individuals have 2 Rh-negative genes presented in their DNA, resulting in no Rh-antigens on the red blood cells. On the other hand, the Rh-positive gene is dominant over the negative one: if one or two Rh-positive genes are presented, that person will be Rh-positive. The persons with 1 Rh-positive gene & 1 negative gene are called carriers, for they can pass on the Rh-negative gene despite being Rh-positive. A carrier parent has a 50:50 chance of giving his or her child a Rh-positive or negative gene.. If both parents are such carriers, what is the chance that their child will be a carrier, too?. ...
Rh immune-globulin acts like a vaccine. It prevents the mothers body from making any Rh antibodies that could cause serious health problems in the newborn or affect a future pregnancy.. A woman also might get a dose of Rh immune-globulin if she has a miscarriage, an amniocentesis, or any bleeding during pregnancy.. If a doctor finds that a woman has already developed Rh antibodies, her pregnancy will be closely watched to make sure that those levels are not too high.. In rare cases, if the incompatibility is severe and a baby is in danger, the baby can get special blood transfusions called exchange transfusions either before birth (intrauterine fetal transfusions) or after delivery. Exchange transfusions replace the babys blood with blood with Rh-negative blood cells. This stabilizes the level of red blood cells and minimizes damage from Rh antibodies already in the babys bloodstream.. Thanks to the success rate of Rh immune-globulin shots, exchange transfusions in Rh-incompatible pregnancies ...

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..

Anti-D and anti-c are the two commonest antibodies that contribute to serious haemolytic disease of the foetus and neonate (HDFN). Current practice in the UK is to monitor these antibodies by CFA quantification, which is considered more reproducible and less subjective than manual titration by tube IAT (indirect antiglobulin test). CAT is widely used in transfusion laboratory practice and provides a more objective endpoint than tube technique. ...
Non RhD isoimmunization causing severe hemolytic disease of fetus and newborn in Rh positive pregnancies: report of 2 cases with review of literature
Neonatal hypoglycemia is a transient or temporary condition of decreased blood sugar or hypoglycemia in a neonate. Temporary hypoglycemia in the first three hours after birth is a normal finding. Most of the time it resolves without medical intervention. The lowest blood sugars occur one to two hours after birth. After this time, lactose begins to be available through the breast milk. In addition, gluconeogenesis occurs when the kidneys and liver convert fats into glucose. Those infants that have an increased risk of developing hypoglycemia shortly after birth are: preterm asphyxia cold stress congestive heart failure sepsis Rh disease discordant twin erythroblastosis fetalis polycythemia microphallus or midline defect respiratory disease maternal glucose IV maternal epidural postmaturity hyperinssulinnemia endocrine disorders inborn errors of metabolism diabetic mother maternal toxemia intrapartum fever Some infants are treated with 40% dextrose (a form of sugar) gel applied directly to the ...
Most people, about 85%, have RH-positive blood. That could support the idea that humans evolved or were derived from Primates. 15 % of humans have RH-negative blood. If blood type is one of least mutable human characteristic, where did the RH negative come from? This question has puzzled scientists for years. There is some evidence that suggests the RH-negative blood group may have appeared about 35,000 years ago. And the appearance was regional and seemed to, originally, be connected with certain groups/tribes of people. (VN: the author has this wrong. Its should read that 15% of humans have the RH negative designation and 85% have the RH positive designation. The fact is of the 85% Positive, many, as much as 60% have one allel from at least one parent. In other words, there are those designated RH positive who have all the traits of Negative, because they have one allel from one parent which makes them RH neg in reality, but they also have RH + traits for the same reason.) ...
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 ...

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 ...

Important Safety Information. RhoGAM® Ultra-Filtered PLUS [Rho(D) Immune Globulin (Human)] (300 μg) and MICRhoGAM® Ultra-Filtered PLUS [Rho(D) Immune Globulin (Human)] (50 μg) are indicated for the prevention of Rh immunization, including during and after pregnancy and other obstetrical conditions or incompatible transfusion of Rh-positive blood.. RhoGAM® and MICRhoGAM® are made from human plasma. Since all plasma-derived products are made from human blood, they may carry a risk of transmitting infectious agents, e.g., viruses, and theoretically the Creutzfeldt-Jakob disease (CJD) agent.. RhoGAM® and MICRhoGAM® are intended for maternal administration. Do not inject the newborn infant. Local adverse reactions may include redness, swelling, and mild pain at the site of injection and a small number of patients have noted a slight elevation in temperature. Patients should be observed for at least 20 minutes after administration.. RhoGAM® and MICRhoGAM® contain a small quantity of IgA and ...

Other than antigen A and B there have the presence of another antigen in human RBC which they termed as Rh factor (from Rhesus) because this was first discovered in the Rhesus monkey, which was discovered by Landsteiner and Weiner in the year 1940. So the terms universal donor and universal recipient no longer remained applicable. People possessing the Rh factor (antigen) are called Rh (+ve) whereas those lacking it are called Rh (-ve). Different the antibodies of ABO system, the Rh antibody does not occur naturally in human plasma i.e., normally this antibody is present neither in Rh (+ve) nor in Rh (-ve) persons. The Rh antibody is created in the plasma of Rh (-ve) persons only when it is exposed to Rh antigen. Thus, Rh antibody is called as an induced antibody.. ...
Named because of the presence or absence of one of eight Rh antigens. It is important to note that most Ameicans are Rh+. Problems can occur in mixing Rh+ blood into a body with Rh- blood. The danger is when the mother is Rh- and the father is Rh+ , and the child inherits the Rh+. The mismatch of an Rh- mother carrying an Rh+ baby can cause problems for the unborn child. The first pregnancy usually proceeds without problems. The immune system is sensitized after the first pregnancy. In a second pregnancy, the mothers immune system produces antibodies to attack the Rh+ blood (hemolytic disease of the newborn). ...
