The recent development of noninvasive testing for fetal anemia with middle cerebral artery peak systolic velocity holds great promise. The critical titer of 1:32 predicted all cases of anemic fetuses and newborns. Obstetrics & Gynecology105(1):24-28, January 2005. Titers were measured at 4-week intervals or less, depending on the initial level and trends in the titers. Am J Obstet Gynecol 1991;165:382–3. 3) Thirty-two-year-old Hispanic female with history of two unexplained miscarriages and negative serologies for SLE. In IVF patients, antithyroid antibodies (ATAs) are treated with intravenous immune globulin (IVIg) before the IVF transfer. Address correspondence to: Richard O'Shaughnessy, MD, 561 Means Hall, 1654 Upham Drive, Columbus, Ohio 43210–1282; e-mail: [email protected]. This is the only published series that investigates the implications of anti‐E during pregnancy. Data were obtained for the computerized database from hospital charts and transfusion service and physician records. Kornstad,4 Jovanovic-Srzentic et al,5 and Bowell et al2 identified 61, 67, and 90 cases, respectively, of anti-E, but did not provide past medical history or any information regarding hemolytic disease of the fetus or newborn, serologic titers, or other indices. In 50% of cases reported here, only maternal serologic titers were necessary to monitor the fetus in utero. Antibodies detected in samples from 21,730 pregnant women. Neonatal hemoglobin was recorded in 7 of these 16 newborns, with all of the results more than 13 g/dL. 8. Both AIHA and HDN may be severe when caused by anti-Kell antibodies. Get new journal Tables of Contents sent right to your email inbox, January 2005 - Volume 105 - Issue 1 - p 24-28, Management of Pregnancies Complicated by Anti-E Alloimmunization, Articles in Google Scholar by Saju D. Joy, MD, Other articles in this journal by Saju D. Joy, MD, Macrosomia: ACOG Practice Bulletin, Number 216, ACOG Practice Bulletin No. Acta Obstet Gynecol Scand 1983;62:431–6. 3. Our data show that a critical serologic titer of 1:32 in the absence of a previously affected fetus warrants further evaluation with amniocentesis, cordocentesis, and possible treatment with intrauterine transfusion. Outcome of treatment. The presence of anti-E potentiates the severity of fetal anaemia due to anti-c antibodies so that referral at lower levels/titres is indicated (unless the fetus has only one of these antigens). There were 5 pregnancies (15%) identified with a fetal or neonatal hemoglobin less than 10 g/dL and 1 pregnancy complicated with hydrops fetalis due to anti-E alloimmunization (Table 1, pregnancies G, J, K-6, L-7, L-5, M). There was 1 intraperitoneal transfusion performed in 1970 for hydrops fetalis. 16. However, there was no information regarding serologic titers or amniocentesis for this group. Weiner CP, Williamson RA, Wenstrom KD, Sipes SL, Grant SS, Widness JA. 6. van Dijk BA, Dooren MC, Overbeeke MA. Am J Obstet Gynecol 1991;165:546–53. Pregnancies affected by anti-E alloimmunization confirmed by a positive direct antiglobulin test due to anti-E or positive E antigen typing in the fetus or newborn were included. 10. Med J Aust 1977;2:453–6. Immune anti-D was detected in 100 pregnancies (by IAT in 50 cases and by enzyme only in the remainder). New York (NY): McGraw Hill; 2001. p. 308–26. The other 16 pregnancies (50%) had titers of 1:32 or greater (Table 1). In 1977 Pepperell et al.2 reported the outcome of 44 women with anti‐E. The objective of this study was to retrospectively review cases of anti-E alloimmunization to determine whether prenatal management similar to that for anti-D is appropriate for anti-E. A computerized database containing the records of all women with alloimmunized pregnancies who had a consultation for a positive antibody screen at The Ohio State University Medical Center from June 1959 to April 2004 was used to identify all pregnant women affected by anti-E. Before conducting this study, permission to retain and evaluate these patients’ data were obtained from The Ohio State University Institutional Review Board. Maximum levels and presence of other associated antibodies are shown in table 1.Fetal and neonatal morbidity and mortality in relation to anti-D levels are shown in table3.. J Obstet Gynaecol Res 2003;29:45–8.

Pepperell RJ, Barrie JU, Fliegner JR. 4 Posts RE: Anti-E and Anti-Kell antibody Posted on: Jul 25, 2013 at 6:47am I had two miscarriages a year ago. 30 mins. Five of 32 (15%) fetuses had Hb less than 10 g/dL and 1 fetus had hydrops fetalis due to anti-E alloimmunization. Queenen JT, Tomai TP, Ural SH, King JC. Within the non-anti-D isolated antibodies, the most frequent was anti-K followed by anti-E and anti-c (Table 2). In our study population, a titer of 1:32 or greater identified all of the anemic fetuses. 22. In some cases, fetal transfusion may be necessary. Management of fetal hemolytic disease by cordocentesis. Looking for ABOG articles? Management of fetal hemolytic disease by cordocentesis. Pepperell et al15 included 44 patients with anti-E with information on newborn Coombs’ status, need for infant exchange transfusion, and stillbirth (1 case). Received July 20, 2004. Objectives To evaluate the association between thyroid autoantibodies and miscarriage and preterm birth in women with normal thyroid function. The antiphospholipid (anticardiolipin) syndrome (APS) is characterized by recurrent venous or arterial thrombosis (clots), recurrent fetal loss, and thrombocytopenia (a reduction in the number of platelets). 800-638-3030 (within USA), 301-223-2300 (international) Middle cerebral artery peak systolic velocity was measured in 2 cases and corroborated information obtained from amniocentesis. The diagnostic criteria require one clinical event and two positive blood test results … Transfus Med 2003;13:227–31. Bowell PJ, Allen DL, Entwistle CC. Significance of red-cell irregular antibodies in the obstetric patient. Your account has been temporarily locked due to incorrect sign in attempts and will be automatically unlocked in Each case was reviewed and followed up contemporaneously by our institutional isoimmunization committee. Multiple clinically significant antibodies were found in 65 (19.3%) pregnancies. This could have been through a blood transfusion, miscarriage, or previous pregnancy with a child that did have the E-antigen. During this period, there were 2 cases of anti-E with titers of 1:32 or greater with normal middle cerebral artery peak systolic velocity (< 1.5 multiples of the mean) measurements. Obstet Gynecol 2002;100:600–11. The use of middle cerebral artery peak systolic velocity is not clarified by these data, but middle cerebral artery peak systolic velocity holds promise as a useful noninvasive tool to monitor the severity of fetal anemia. Of the 270 red blood cell antigens with the potential to cause hemolytic disease of the fetus or newborn, Rh(D) antigen has been the most studied.1 However, given the widespread use of Rh(D) immune globulin, there has been a relative increase in the importance of non-Rh(D) alloimmunization as a cause of hemolytic disease of the fetus or newborn.2–5 Of the remaining 43 antigens in the Rh system, the other frequently observed antigens include C, c, E, and e. The obstetrician encounters a dilemma upon demonstration of anti-E during routine antenatal screening for red blood cell antibodies.

Beginning in 1987, fetal anemia was confirmed by cordocentesis, and fetal transfusion was considered when the hemoglobin was less than 10 g/dL or hematocrit less than 30%.11–13 In patients who required intrauterine transfusion therapy, only data obtained before the first transfusion is reported. This review identified anti-E in 283 pregnancies from September 1966 to April 2004. APS provokes blood clots in both arteries and veins as well as pregnancy-related complications such as miscarriage, stillbirth, preterm delivery, and severe preeclampsia. Working off-campus? 17. This laboratory follows published guidelines endorsed by the American Association of Blood Banks.7 An isoimmunization committee evaluated all laboratory reports and recommended a care plan for each of these patients as described below. Anti-e is implicated in Hemolytic Transfusion Reactions and Hemolytic Disease of the Fetus and Newborn. Br J Obstet Gynaecol 1986;93:1038–43. Antibody formation can be triggered by: Complications early in pregnancy such as miscarriages, ectopic pregnancies, or terminations Injury to the stomach during pregnancy Subjects: 90 women (median age 33 (range 22-43)) with a history of recurrent miscarriage (median number 4 (range 3-15)) and persistently positive results for phospholipid antibodies.
