Bethany and Molly return to record with Dr. Markham, a well-loved maternal fetal medicine specialist who has treated many HDFN babies. They cover many questions submitted by allo moms including:
Does a high titer or low titer mean the baby is antigen positive or negative?
If mom’s antibodies are too low to titer, what does that mean for the rest of the pregnancy?
Is it too risky to pursue another pregnancy with a titer of 2,048?
Is it safe to have an external cephalic version (ECV) for breech babies in alloimmunized pregnancy?
What is the best mode of delivery for an alloimmunized pregnancy?
When should we deliver if the pregnancy didn’t need IUTs? If the pregnancy is low titer?
Can antibodies cause hydrops or death without a high MCA Doppler ultrasound first?
How has a patient made you, the doctor, feel valued?
Can obesity make IUTs more difficult?
The women close with some patient-submitted stories of the most shocking thing that happened during an IUT, with Dr. Markham sharing a hilarious one of her own.

S3E2: Low Titer Alloimmunized Pregnancies
Over half of alloimmunized pregnancies begin with a low antibody titer, and a portion stay low throughout the pregnancy. Others begin low and later rise to critical levels. This episode is dedicated to management of the low titer pregnancy and how to anticipate a potential change in disease trajectory if titers increase.
Bethany and Molly include management recommendations and stories submitted by low titer moms before transitioning to a special interview with allo mom Amanda, whose pregnancy began as a low titer pregnancy before taking a surprising turn. We meet Amanda in this episode before resuming the second half of her HDFN journey in this season’s final episode, Incredible HDFN Survival Stories.
Key aspects of low titer disease management:
Determine baby’s antigen status if possible. If not possible, monitor as if antigen positive. If the baby is certainly antigen negative, the pregnancy proceeds as normal and there is no need to do anything further beyond standard pregnancy careEstablish care with an MFM and determine up front if this MFM is able to do IUTs on your baby if your disease progresses. If not, have a referral plan set upCheck titers every 4 weeks in the first and second trimester, then every 2 in the third trimesterWeekly fetal assessment beginning at 32 weeks (Nonstress tests and biophysical profiles).Delivery at 37-38 weeksFollow all neonatal recommendations (establish a plan with pediatrician in advance if possible b/c they are likely to be doing the follow-up care) - bilirubin consistent with AAP guidelines which may include daily testing after discharge for a week or more, and hemoglobin/hematocrit weekly for the first six weeks and until hemoglobin/hematocrit increases or is in stable normal range for two consecutive weeksDelivery timing 37-38 weeks: ACOG Medically Indicated Late Term and Early Preterm Deliveries.

Top 5 Prenatal Things (in no particular order):
Bethany:
Quick referral to MFM (and a list of MFMs worldwide who specialize in treating alloimmunized pregnancies)Preventative medications accessible to all women who need them (Rh immune globulin/RhoGAM; intravenous immune globulin, plasmapheresis for severely affected pregnancies)Weekly, accurate MCA scans beginning at 16-17 weeks for those with critical titers or previously affected babies; for those with early onset severe disease, starting soonerMFMs who collaborate with other experts and refer when necessaryIUTs performed on time, using fetal paralytic meds, by providers with ample experience performing IUTs who know to space and attempt the last IUT at 34-35 weeks if possible(Honorable mention): Referring all women with positive antibody screen to Allo Hope Foundation (Honorable mention): Delivery at 37-38 weeks unless you are certain baby is antigen negativeMolly:
Immediate referral to MFM after positive antibody screenWeekly MCA scans for critical titer/previously affected pregnancies (Weekly MCA recommendation from the group who developed MCA scans: www.academia.edu) Establishing global referral centers for IUTsAn awareness that the seriousness of the disease can change at any time (e.g., low titers can jump up, first pregnancies can be severely affected - will result in closer monitoring)Go in if you notice a change in baby’s movement or something doesn’t feel right about your treatment or monitoringTop 5 Neonatal Things (in no particular order):
Molly:
Establishing neonatal care in advance of delivery (NICU/hematology in cases where pregnancy has needed treatment or high titers; pediatrician for lower titers)Create a fetal care record for your baby (AHF is developing this and it is not yet publicly available: e-mail us at [email protected] if you would like to use a draft version in the interim)Following bilirubin closely after birth and doing a trial off of lights before discharge (AAP hyperbilirubinemia guidelines: aap.org/pediatricsWeekly hemogobin/hematocrit after discharge until consistently trending upward or stable in a healthy range for 2+ weeks (Neonatal management from the Netherlands: research.rug.nlFollow the trend. Do not rely on one laboratory reading. Two readings are needed for a trend. Bili should be trending down; hemoglobin/hematocrit increasing.Bethany:
Continuity of care from MFM to neonatologist to pediatrician to pediatric hematologistTest cord blood at birth (hematocrit/hemoglobin, bilirubin, Direct Coombs Test (DCT))Providers who understand how hemolytic jaundice and hemolytic anemia work (as opposed to newborn jaundice and iron deficiency anemia)Close monitoring and aggressive treatment for hyperbilirubinemia (see AAP guidelines linked above)Follow-up blood tests weekly after hospital discharge -

Over the Past 2 seasons Bethany and Molly have discussed the lack of consistent, accessible treatment and the current ways we can treat an alloimmunized mom and her children with HDFN, but on this episode with Dr. Moise we discuss a bright future. Can a simple carbon monoxide reader replace a needle procedure to monitor for anemia? Can a drug stop antibodies from crossing the placenta entirely? We look to the cutting edge of medical treatment for disease that brought these women together.

This special two-part episode of the Allo Podcast is intended for our regular listeners and for those who are unfamiliar with alloimmunization. A beautiful testament to the grace of humanity, Bethany and Molly sit on the floor of Molly’s bedroom with guest Rose Murage, a native Kenyan with a harrowing pregnancy journey. Rose shares the pain of watching her first two children die tragic, inexplicable deaths. But when Rose reached out to Bethany for help, a new journey began to diagnose Rose with red cell alloimmunization and find a way towards a living baby in a country with limited resources. Join us for the first part of Rose’s story as she tells of her life in Kenya, the short physical lives of Alexis and Max, the obstacles she overcame to seek treatment, and the gift of an American doctor and a network of activists to heal a family.
Definitions for the show notes as they appear in the episode:
Rhogam shot/Rh immune globulin/Anti-D injection: An injection for Rh negative women to help prevent them from developing Anti-D antibodies during pregnancy. This needs to be administered after pregnancy bleeding, at 28 weeks, and after birth. Access to this injection is limited in developing countries and often not affordable for the average family.ICT test: Indirect Coombs Test, a blood draw on the mother to see if she has red cell antibodies (alloimmunization) which can attack her baby's blood and cause HDFN. This is also called an antibody screen. DCT test: Direct Coombs Test, a blood test that is run on babies after birth to see if mom's antibodies are attaching to their blood cells. A baby with a positive DCT usually means they have hemolytic disease of the fetus and newborn (HDFN).MCA Doppler scan: Specialized ultrasounds that detect fetal anemia. This is the best way to monitor a baby at risk for HDFN to determine if they need an intrauterine blood transfusion to treat their anemia. An MCA value of 1.0 is normal, and 1.5 means the baby is anemic and needs a transfusion. In Kenya, very few hospitals can conduct these MCA Doppler ultrasounds accurately.IUT: Intrauterine transfusion, currently the only way to treat a baby with HDFN in utero. This is a blood transfusion into the baby's umbilical vein using a long needle through the mother's abdomen.Rhesus positive: This means that a person has a positive blood type (D antigen positive). Rose's body is Rhesus negative and makes antibodies to Rhesus positive (D antigen positive) blood. Any donors for her baby would need to be Rhesus negative so that her antibodies do not destroy the newly donated blood.What can you do as a listener?

A powerful episode that you may not know you needed. Bethany and Molly share from the heart in this special episode that will open you up to an awareness and understanding you may not have considered before. Grief and trauma are more common than you think across the motherhood journey, but especially in pregnancies affected by alloimmunization. This episode is intended for any listener who has experienced loss related to pregnancy and motherhood, no matter how big or small, and for those who want to better support a person who has experienced pregnancy trauma and grief. Bethany and Molly share about grief from the loss of a child, and also grief from the loss of expectations, loss of trust, loss of hope for what pregnancy and motherhood would feel like. With the help of insights from previous guests, they discuss a path toward hope and healing the wounds we suffer with loss of a child, the burden of high risk pregnancy, and how to honor our losses.

Amber already had a difficult and rare blood disorder (TTP) but treatment for her unknown disease resulted in her developing antibodies, resulting in alloimmunization in her first pregnancy. A chance visit with a different doctor made the difference with her first child, but extraordinary measures were needed when she became pregnant with twins. Bethany and Molly are in for quite a tale of HDFN in already unusual circumstances.

Navigating the American medical system is not new to a clinician like Katie, but experiencing it as a rare disease patient is a different story entirely. This week Bethany and Molly interview Allo Hope Foundation’s Director of Development, Katie Shanahan, a nurse practitioner who became sensitized after not receiving Rh immunoglobulin (RhIG, sometimes called RHOGAM). Her alloimmunization progressed rapidly as her son developed significant HDFN in her first alloimmunized pregnancy. Katie shares stories of IUTs and NICU life in such a relatable and informative way. Also, the women discuss the process of in vitro fertilization and how preimplantation genetic diagnosis can make Katie’s next pregnancy a very different experience.

Okay, we’ve had the podcast baby, now what? Molly and Bethany discuss the medical measures needed to keep the baby healthy after they join us on the other side. As our new patient is born we have a new series of information and tips to keep baby safe until baby is finally cleared of mom’s antibodies, usually by 12 weeks of age.
Episode themes:
Why baby is still affected by mom’s antibodies after birthTwo major effects of HDFN: hyperbilirubinemia and anemiaMonitoring bilirubin via blood test or photo sensor.Transfusions: exchange, top-up and IVIG, and tips if your baby needs oneDelayed onset anemia: why a baby with no symptoms at birth needs to be monitoredWeekly blood tests for reticulocyte count and hematocrit/hemoglobinWhen to treat anemia and hyperbilirubinemiaWhen we’re done with HDFNHDFN babies do not need iron supplements: request ferritin tests before care teams give iron supplementsSpecial considerations in babies who received intrauterine transfusions (IUTs) in uteroBaby’s pre-birth medical history is not automatically recorded in baby’s medical recordTerminology used in this episode:
Bilirubin: The substance formed when red blood cells are broken down. Bilirubin is part of the bile, which is made in the liver and is stored in the gallbladder. The abnormal buildup of bilirubin causes jaundice.Exchange transfusion: A blood transfusion in which the patient's blood or components of it are exchanged with (replaced by) other blood or blood products.Hematocrit: The ratio of the volume of red blood cells to the total volume of bloodHemoglobin: A protein inside red blood cells that carries oxygen from the lungs to tissues and organs in the body and carries carbon dioxide back to the lungs.Hyperbilirubinemia: High levels of a product produced when red blood cells are broken down. In the case of alloimmunization, they are broken down by the mother’s antibodies. Excess bilirubin can cause jaundice, kernicterus, hearing loss, tooth enamel problems, permanent brain damage or even death if left untreated.Kernicterus: Bilirubin-induced permanent brain damage as a result of high levels of bilirubin, also called bilirubin encephalopathy. Signs of Kernicterus are considered a medical emergency and include: a high pitched cry, arched back, and an inconsolable infant.Reticulocyte count (Retic): This is a measure of how many immature blood cells are in the bloodstream. These are future RBCs and can give an idea of how quickly a baby is making new blood to replace what the antibodies are destroying. It can be used to decide if a top up transfusion is needed or if another check in a couple days will suffice.Top-up transfusion: Adding blood or blood products without removing any blood, these are also known as simple transfusions.Linked mentioned in this episode:

Direct Antiglobulin Test (DAT): This test looks for antibodies that are bound to red blood cells and is typically done on infants. With specific antibodies, this test can be negative even when the baby is still affected and needing treatment. Bilirubin (Bili): A product created when red blood cells are broken down. In the case of alloimmunization, they are broken down by the mother’s antibodies. Excess bilirubin can cause jaundice, kernicterus, hearing loss, tooth enamel problems, permanent brain damage or even death if left untreated.Complete Blood Count (CBC): This is a laboratory test that checks the levels of a variety of blood cells and includes hemoglobin, hematocrit, neutrophil count, reticulocyte count, and more.Allo Hope Terminology Library https://allohopefoundation.org/library/terminology/
