e83-e88. vol. The usual dose of anti-Rh globulin given to the mother (300 µg) protects against up to 30 mL fetal whole blood (15 mL fetal red blood cells); if a larger hemorrhage is suspected because of apparent acute blood loss and shock in the infant, estimation of the amount transfused by a Kleihauer-Betke test on the mother’s blood is indicated to estimate the dose of anti-Rh globulin needed. Prophylaxis for maternal Rh isoimmunization is possible through administration of anti-Rh globulin to Rh-negative women after miscarriage or abortion, during each pregnancy at 28 weeks’ gestation, and after delivery of an Rh-positive infant. The most common neonatal problem today is that of anemia developing following discharge. Home » Decision Support in Medicine » Pediatrics. 2006. pp. Effects of intravascular, intrauterine transfusions on prenatal and postnatal hemolysis and erythropoiesis in severe fetal isoimmunization. The rate of severe morbidity is approximately 5%, whereas the mortality rate in otherwise healthy infants is less than 0.5%. Anemia caused by hemolysis in the immediate newborn period is typically associated with severe hyperbilirubinemia. INTRODUCTION and DEFINITION:Hemolytic Disease of the Newborn (HDN), also known as erythroblastosis fetalis, isoimmunization, or blood group incompatibility, occurs when fetal red blood cells (RBCs), which possess an antigen that the mother lacks, cross the placenta into the maternal circulation, where they stimulate antibody production. Before the use of anti-Rh globulin, the incidence of Rh isoimmunization was 10% of Rh-negative mothers after one pregnancy, which decreased to 1.8% with a single postpartum prophylactic dose of Rh immunoglobulin, and to 0.14% with an additional prophylactic dose at 28 weeks. Most commonly, the mother is blood type O and her baby is A or B; less often the mother will be Rh negative and the baby Rh-positive. A fiberoptic phototherapy blanket alone is The risks include metabolic disturbances, thrombocytopenia, infection, necrotizing enterocolitis, and death. Rh- antigen • Rh- system – LANDSTEINER – 1940 • Rhesus blood group antigens – C, c, D, E, e • Short arm of chromosome 1 • RH (D) – most immunogenic • Person lacking D-antigen called Rh-ve • Lewis and Kell • 38th day after conception • INDIA- incidence =8-10% The ICD code P55 is used to code Hemolytic disease of the newborn . What laboratory studies should you request to help confirm the diagnosis? All Affected Infants, i.e., those which are Coombs positive: Parents: Parents need to be aware that affected infants who may or may not have been anemic at birth (especially those who received one or more in utero erythrocyte transfusions) are at considerable risk for developing clinically significant anemia during the first 3-4 months of life. vol. Indirect Coombs test and direct antibody test results are positive in the mother and affected newborn. 2007. pp. If you are able to confirm that the patient has hemolytic disease of the newborn, what treatment should be initiated? After initial stabilization, the infant should be transferred to the NICU. The antibodies will attack any Rh-positive blood … This process (ABO incompatibility) is generally mild, and with unpredictable severity from one pregnancy to the next, although occasionally infants are severely affected. • All pregnant women must be screened for the presence of circulating antibodies that can cause fetal hemolysis and neonatal hemolytic disease. 2004. pp. The nomogram published by the AAP is quite useful. vol. Management of this condition follows that described elsewhere in this manual (see section on "Management Of Hyperbilirubinemia in the Newborn Period"). (Updated review of hemolytic disease of the newborn), Smits-Wintjens, VEHJ, Walther, FJ, Rath, MEA. Occasionally there is an antibody to a so-called minor blood group antigen such as Duffy, Kell, or others. The heme oxygenase system has protean effects, similar to nitric oxide pathways, so positive and negative consequences are difficult to predict. Intensive phototherapy with maximal exposure of body surface is most effective, including the combined use of conventional phototherapy with a supplemental fiberoptic phototherapy blanket under the infant. Nevertheless, when signs of acute bilirubin encephalopathy are present or the bilirubin continues to rise relentlessly despite other measures, this is the best option for lowering the bilirubin level and interrupting the hemolytic process. Am J Obstet Gynecol 1991;165:546-553. (Extensive review of available literature regarding management of hyperbilirubinemia), Eder, AF. This condition occurs when there is an incompatibility between the blood types of the mother and baby. “Metalloporphyrins in the management of neonatal hyperbilirubinemia”. There is the possibility of infection, metabolic derangements during and after the procedure, thrombocytopenia, necrotizing enterocolitis, and death. Fortunately, this is much less common today with modern antenatal diagnosis and treatment, including intrauterine intravascular transfusions, which prevent and even reverse these findings before birth. Blood type and DAT on the cord blood or infant blood, looking for antibody on the infant’s red blood cells. The goal of therapy is to avoid this outcome. As a result, the baby will be affected by the antibodies being produced by the mother.Blood types are not the same from each other due to the small molecules found on the surface of the blood cells. The total bilirubin, however, should be used for all decisions regarding therapy. The chance for this occurring again in future pregnancies is unpredictable. Although metalloporphyrins appear to be very effective in preventing bilirubin production, the preferred compound, dose, and method of administration is not known. vol. 2011. pp. Exchange transfusion: Central access is necessary as is the use of blood products. Objective: It is stated that the direct antiglobulin (Coombs') test (DAT) may be negative in ABO hemolytic disease of the newborn. 15. For many years, the use of metalloporphyrins, competitive inhibitors of heme oxygenase (the initial and rate-limiting enzyme involved in heme degradation) has been proposed for the prevention of bilirubin production in infants with known hemolytic processes. These products are made from human plasma, and there is a theoretical risk for transmission of infections (although not reported) or other serious side effects (rare in newborn). John A. Widness, MD 920-928. 31. Newborn , male, premature (33 weeks gestation , 1,400 grams) Z38.00 ABO incompatibility is a common and generally mild type of haemolytic disease in babies. Cognitive deficits are rare. P55.1 is a billable ICD code used to specify a diagnosis of aBO isoimmunization of newborn. If blood is not needed to treat anemia, hypotension may be corrected with Plasmanate®. What other disease/condition shares some of these symptoms? F83-88. What are the possible outcomes of this disease? No sponsor or advertiser has participated in, approved or paid for the content provided by Decision Support in Medicine LLC. Severe blistering of the skin and agitation during phototherapy may be a sign of congenital porphyria, which is very rare. vol. Intravenous fluid administration for hydration is not generally needed unless the infant is being fed nothing by mouth for possible exchange transfusion or other reasons, or if albumin or intravenous immunoglobulin (IVIG) is to be administered. Outcome of previous pregnancies, i.e., fetal & neonatal deaths, prematurity, etc. 1. The reduced rates of isoimmunization in Rh-negative mothers with ABO incompatibility were noted years ago in 1943 by Levine. Hyperbilirubinemia does not occur before birth because bilirubin is ordinarily not conjugated before birth. vol. A condition characterized by the abnormal presence of ERYTHROBLASTS in the circulation of the FETUS or NEWBORNS. Life threatening clinical signs can occur in the presence of superimposed acute illnesses, i.e., viral infections. O-A incompatibility is most common, but O-B incompatibility is more likely to be problematic. Sign in 2009. pp. The risk of serious morbidity is approximately 5%, whereas the risk of mortality in an otherwise healthy term infant is less than 0.5%. Signs of acute bilirubin encephalopathy include lethargy, poor feeding, and hypotonia, progressing to irritability alternating with stupor, high-pitched cry, and hypertonicity with retrocollis and opisthotonus. Management of fetal hemolytic disease by cordocentesis: I. 114. Ultimately, there is apnea, coma, seizures, and death. ABO incompatibility is a complication that could possibly occur during pregnancy. 2010. pp. The smear will frequently show microcytic spherocytes if an isoimmune hemolytic process is present. 297-316. Due to maternal screening for this condition, these infants are almost recognized prior to delivery. In the case of severe erythroblastosis fetalis, there may be severe clinical manifestations, including generalized edema, respiratory failure due to surfactant deficiency with or without bilateral pleural effusions, hypotension and cardiac failure due to severe anemia (sometimes worsened by pericardial effusion), ascites, hepatosplenomegaly (due to congestive heart failure as well as extramedullary hematopoiesis), and skin lesions (blueberry muffin spots, palpable purpura), also due to extramedullary hematopoiesis. (Review of all forms of hemolytic disease in the newborn, including antibody-mediated), Ross, MB, Alarcon, P. ” Hemolytic disease of the fetus and newborn”. Copyright © 2020 Haymarket Media, Inc. All Rights Reserved Severely Affected Infants: Following transfer to the NICU most severely affected infants warrant having an umbilical or peripheral arterial catheter inserted for monitoring blood pressure, pH and blood gases. 56. If you carry this protein, your blood is Rh positive. For this reason, anemia will continue to be a problem long after the hyperbilirubinemia has resolved, and may require one or more transfusions of packed red blood cells (top-up transfusion) during this time. Other clinical manifestations that might help with diagnosis and management. This may occur whether or not the infant had exchange transfusion, IVIG, or intrauterine transfusion. (Review of potential utility of heme oxygenase inhibitors to prevent excessive heme catabolism in susceptible neonates), Watchko, JF. 31 More recent studies have demonstrated that the same protective effect of incompatibility extends to non-RhD isoimmunization, with lower rates than expected based on population at risk. (Extensive review of available literature regarding management of hyperbilirubinemia), (Discussion of minor blood group antigens and antenatal monitoring for severity of fetal involvement), (Extensive review of antenatal management of Rh-sensitized mother and use of intrauterine transfusion), (Although both total bilirubin and bilirubin/albumin ratio are strong predictors of acute and longterm outcome, bilirubin/albumin ratio does not improve prediction over total serum bilirubin alone), (Description of relative proportions and severity of O-A and O-B incompatibility from a prospective population cohort), (Large population reviewed for instances of bilirubin concentration 30 mg/dL or more for determination of etiology, incidence and outcome), (Extensive review of mechanism of action of phototherapy and bilirubin metabolism), (Review of all forms of hemolytic disease in the newborn, including antibody-mediated), (Updated review of hemolytic disease of the newborn), (Questions the efficacy of IVIG in hemolytic disease), (Review of potential utility of heme oxygenase inhibitors to prevent excessive heme catabolism in susceptible neonates), (ABO hemolytic disease as an important cause of exaggerated hyperbilirubinemia), Close more info about Hemolytic disease of the newborn (alloimmunization), OVERVIEW: What every practitioner needs to know. Although infants can become sufficiently anemic to develop congestive heart failure, more often they manifest evidence of poor feeding or lack of activity. As with criteria for phototherapy, criteria for exchange transfusion vary with infant age, gestation, associated illness, and albumin concentration, and is also outlined by the AAP in nomogram form. Other causes of hemolysis, for example, hereditary spherocytosis or glucose-6-phosphate dehydrogenase deficiency may present with early and/or excessive jaundice, but the Coombs or DAT test is not positive. 2008. pp. Rh-isoimmunization (incompatibility to the Rh blood type) is preventable, and prevention is preferable to treatment. NeoReviews. "Hemolytic" means breaking down of red blood cells "Erythroblastosis" refers to making of … This code description may also have Includes , Excludes , Notes, Guidelines, Examples and other information. If present, ascites may create ventilatory embarrassment and paracentesis should be considered. o Day 1: consider isoimmunization (ex. P55.1 - ABO isoimmunization of newborn The above description is abbreviated. Folic acid 50 µg orally daily may be helpful in maintaining the maximal hematocrit possible. Register now at no charge to access unlimited clinical news, full-length features, case studies, conference coverage, and more. N Engl J Med. 2. Mild to Moderately Affected Infants: Treatment of less severely affected infants starts with correction of hypotension and acidosis. Intravenous immune globulin in neonatal ABO isoimmunization: factors associated with clinical efficacy. This can cause a problem if the baby's blood enters the mother's blood flow. A bilirubin-albumin ratio of 7:1 is considered safe under most circumstances. 2010. pp. (Questions the efficacy of IVIG in hemolytic disease), Stevenson, DK, Wong, RJ. 721-742. They are then given an additional dose of anti-Rh globulin after delivery to further protect them from sensitization. (Although both total bilirubin and bilirubin/albumin ratio are strong predictors of acute and longterm outcome, bilirubin/albumin ratio does not improve prediction over total serum bilirubin alone), Kaplan, M, Hammerman, C, Vreman, HJ. Clin Perinatol. Severely Affected Infants: Immediately following birth, the severely affected infant may have problems with circulatory and respiratory failure due to intrapartum depression and anemia, not bilirubin toxicity. Other Clinical Manifestations That Might Help with Diagnosis and Management Pretreatment with 25% albumin has been shown to increase the amount of bilirubin removed, and to decrease the need for further exchange transfusion and the length of subsequent phototherapy needed. “Update on HDFN: new information on long-standing controversies”. Exchange transfusion with O-negative blood compatible with the mother to increase the hematocrit without further volume overload is preferred over simple transfusions; exchange transfusion will also decrease the bilirubin load. Rh, ABO incompatibility) and congenital infection If mother is blood type O+, obtain infant blood type and direct antiglobulin test CancerTherapyAdvisor.com is a free online resource that offers oncology healthcare professionals a comprehensive knowledge base of practical oncology information and clinical tools to assist in making the right decisions for their patients. Therefore, treatment (phototherapy or exchange transfusion) would be instituted earlier in an infant with a low serum albumin concentration than in one with a robust concentration. 127. 680-686. Still, ABO incompatibility and other alloantibodies against minor blood group antigens have emerged as significant causes of HDN. Kernicterus/chronic bilirubin encephalopathy is a permanent and nonprogressive condition manifesting clinically as choreoathetoid (dyskinetic) cerebral palsy, limited upward gaze, deafness (auditory dyssynchrony, which is abnormal brainstem auditory evoked response in the face of normal otoacoustic emissions), and enamel dysplasia of the deciduous teeth. Thus, significant jaundice in neonates who are A-B incompatible with their mothers but DAT test negative is often attributed to isoimmunization and another diagnosis is … (Extensive review of antenatal management of Rh-sensitized mother and use of intrauterine transfusion), Iskander, I, Gamaleldin, R, Houchi, SE, Shenawy, AE. As noted above, if severe anemia is present, a small exchange transfusion with packed red cells, 20-40 mL/kg, may be indicated. IgM antibodies do not cross the placenta, but IgG antibodies, if present, can cross and bind to the infant’s red blood cells, causing removal by the infant’s reticuloendothelial system. Rh negative women are given injections of a medicine called Rh immune globulin (RhoGAM) to keep their body from making Rh antibodies. Your use of this website constitutes acceptance of Haymarket Media’s Privacy Policy and Terms & Conditions. Breast-feeding can be supplemented with expressed breast milk or formula if the infant is having difficulty latching on; use of a breast shield may also be helpful. With rare exceptions, it is presently possible to prenatally detect all non-ABO affected fetuses by testing for antibodies in maternal blood. Although used in Europe and studied in the United States, no metalloporphyrin is currently approved by the US Food and Drug Administration for clinical use. (Extensive review of mechanism of action of phototherapy and bilirubin metabolism), Murray, NA, Roberts, IAG. To view unlimited content, log in or register for free. If you don't carry this protein, your blood is Rh negative. All Rights Reserved. Hemolysis due to … It is an immune system reaction that takes place when an infant’s blood type is different from their mother’s type. J Pediatr 1990;117:447-454. An infusion of D10W with maintenance electrolytes should be initiated through an arterial line or peripheral IV. Hemolytic disease of the newborn has become a less and less common condition due largely to improved preventative measures such as the maternal administration of Rh immune globulin during the early 3rd trimester and the immediate postpartum period. In cases where a severely affected, anemic infant is anticipated (a rarity in recent years), packed type O Rh- blood cross-matched against maternal serum should be available for possible immediate booster transfusion (see Neonatal Blood Bank Procedure Manual). ABO incompatibility is less severe than Rh incompatibility because there are fewer group A or B antigen sites on neonatal red blood cells compared with Rh antigens, allowing sensitized A or B cells to survive longer in the infant’s circulation than with anti-Rh antibodies. Since the maternal antibodies persist in the newborn for 2-3 months, there will be ongoing destruction of red blood cells (hemolysis) for the first 8-12 weeks of life. Most recently fetal cordocentesis has been utilized with increasing success to detect and to treat fetal anemia, i.e., with intravascular transfusion, in pregnancies identified prenatally, perinatal mortality and morbidity have been significantly improved. 2014. pp. A double-volume exchange transfusion (160 mL/kg, with type O, Rh-negative blood compatible with the mother, irradiated and leukodepleted) will remove approximately 85% of the infant’s cells, as well as much of the antibody, and will reduce the total bilirubin load by approximately 25% by removing that which is circulating in the blood. Minor blood group hemolytic disease is extremely rare, since the overall potency of minor blood groups in inducing antibodies is significantly lower when compared with that of Rh (D) antigen. 92. Although recommended in the 2004 AAP Committee statement, a Cochrane review in 2002 recommended trials of higher quality be performed before endorsing this therapy. 2013. pp. Similarly, double-bank phototherapy will expose more surface area than a single bank of lights and is therefore more effective. Arch Dis Child Fetal Neonatal Ed. 188-195. ABO incompatibility is the most common maternal-fetal blood group incompatibility and the most common cause of hemolytic disease of the newborn (HDN). In the case of Rh incompatibility, the DAT result will likely be strongly positive, and the infant will likely be significantly affected.
