In our quest to share the experience of Alloimmunized moms, Bethany interviewed Monique Kinney, a contributor to the Allo Hope Foundation. Monique founded the premier Facebook support group for Alloimmunized moms before the Allo Hope Foundation was started in 2019. 

Episode themes: 

• Monique’s proactive discovery of her Anti-E antibody status
• The Bad Number
• Advice for post-birth
• Mid-Pregnancy Postpartum Anxiety
• Advocacy against hospital policy
• Being your baby’s medical record

Terminology used in this episode: 

• Antibody Evanescence: The waning of antibodies over time following an exposure to the immunized antigen. Once a patient develops antibodies, the antibodies never truly disappear. Fewer than 30% of antibodies are estimated to be detectable by current methods.
• Antibody Boostering: When an antibody undetectable during cross-matching is suddenly detectable again. Antibody boostering happens in patients who were earlier found to have alloantibodies, but then experienced antibody evanescence. Boostering can result in the antibodies coming back in an anamnestic manner, including hyperhemolysis.

Why do we have to advocate so hard for adequate care for Maternal Alloimmunization? This disease is so rare, many maternal fetal medicine doctors (MFMs) simply do not treat it often. Finding the right doctor with experience in this disease can change the outcome of your pregnancy experience and the health of your baby. 

Episode topics: 

• Common barriers to good care
• Doctor’s reflection on the patient/provider relationship
• Understanding your choices with an MFM 
• Establishing mutual trust with your Doctor 
• What to look for in an MFM
• Your body, your baby, your care
• The things to look out for in a doctor 

Green Flags:

• Doctor offers cell free fetal DNA tests if appropriate
• Doctor discusses all appropriate treatment options with you in a collaborative way
• Planning for possibilities of IUTs
• Doctor increases their own education on alloimmunization if needed
• Doctor follows up after birth 
• Provides ultrasound 24 hours after IUT 
• Gives paralytic to baby in IUT
• IUT in an operating room
• Doctor communicates with post birth care providers 
• Cares about your emotional and mental well being

Bethany’s story continues with the growth of her family, learning from the mistakes made in Lucy’s treatment for severe HDFN. After Bethany becomes pregnant she goes to great lengths to keep her babies safe, moving out of state, undergoing frequent plasmapheresis and IVIG, many IUTs, NICU time, and post-birth transfusions. While Bethany’s proactive pursuit of treatment leads to the delivery of 3 healthy children, the loss of Lucy motivates her toward activism and the founding of the Allo Hope Foundation. 

Episode themes: 

• Educating yourself 
• Finding an excellent doctor
• Pursuing other family options (sperm donation, adoption, preventative treatment)  
• Preventative treatments for severe HDFN
• The Rainbow Baby
• Making the decision to continue
• Unexpected deliveries 
• One more time
• The Blog: Losing Lucy and Finding Hope
• The Allo Hope Foundation 

Terminology used in this episode: 

Cell-Free Fetal DNA (cffDNA): This noninvasive test uses the fetal DNA that is found floating in maternal circulation to check the fetal red cell antigen status. It requires a blood sample from the mother. cffDNA can be used for pregnancies complicated by anti-Kell, anti-D, anti-C, anti-c, anti-E, and anti-e antibodies.

Intravenous Immunoglobulin (IVIG): An infusion of mostly IgG immunoglobulins that is made by extracting the immunoglobulins from the plasma of ~1,000 donors. It is thought to lessen the mother’s antibody response and delay fetal anemia. It can also be given after birth to newborns to treat hyperbilirubinemia. It may affect the efficacy of live virus vaccines for up to a year after administration.

Plasmapheresis: A procedure where the blood is removed from the mother, the antibody-rich plasma is removed, and blood cells are returned. This can decrease the antibody titer.

Host and Allo Hope Foundation founder Bethany Weathersby tells the story of Lucy, her daughter, who passed from HDFN. Her loss sparked the blog Losing Lucy and Finding Hope, which grew into a resource for alloimmunized mothers seeking help and support. Lucy’s loss gave Bethany the drive to advocate for alloimmunized moms and HDFN babies around the world, and to advocate for the lives of her future children (more on that in Part 2). Lucy’s life has continued to impact the lives of countless babies with HDFN.

Note that since the time of this recording, Allo Hope Foundation has changed its recommendation such that a critical titer for Kell is any titer (previously 4), consistent with the ACOG Practice Bulletin, available here: https://pubmed.ncbi.nlm.nih.gov/29470342/

Episode themes: 

• Diagnosis of alloimmunization
• Family life during an alloimmunized pregnancy
• The life saving power of advocacy
• Severe, early HDFN
• Fetal death, stillbirth  and grief

Terminology used in this episode: 

• PSV: the measurement gained from the MCA Doppler ultrasound. It is the maximum velocity (sometimes called Pmax) that blood is moving through the middle cerebral artery. Anemic blood flows faster than nonanemic blood. The PSV is used to calculate the Multiples of the Median (MoM) value to check for anemia.
• MoM: The result of the calculation to see if the baby is anemic. The peak systolic velocity (PSV) and gestational age are used to calculate the MoM. A result of 1.3 indicates mild anemia. Numbers of 1.5 or higher indicate moderate to severe anemia and signals the need for an intrauterine transfusion or delivery. Lucy’s was 2.5

Severe alloimmunization is surrounded by vague information and confusion, but this episode will prepare patients and providers for available treatment. Patients with previous fetal death, previous IUT before 24 weeks, or with a titer of 256 or higher may be diagnosed with severe disease. Remember, options do exist for severe situations, and prevention and monitoring are the key elements to having a healthy baby. This episode discusses IVIG and plasmapheresis, early MCA Scans and early IUTs, and phenobarbital. 

Episode themes: 

• Common misconceptions about severe disease
• Defining severe disease
• Delaying IUTs with IVIG and plasmapheresis treatment
• What to expect during IVIG and plasmapheresis
• Oral phenobarbital for mom to reduce need for newborn transfusion after birth
• Tips for patients entering a pregnancy complicated by severe disease

IVIG: Intravenous Immunoglobulin:  An infusion of mostly IgG immunoglobulins that is made by extracting the immunoglobulins from the plasma of ~1,000 donors. It is thought to lessen the mother’s antibody response and delay fetal anemia. It can also be given after birth to newborns to treat hyperbilirubinemia. 

Phenobarbital: An oral medication given to an alloimmunized mother before baby’s birth to improve baby’s liver function, allowing the baby to more efficiently break down bilirubin and reducing the need for exchange transfusion after birth.

Plasmapheresis: The process of removing the plasma from the body whereby the blood is removed and run through a machine that separates the plasma from the red blood cells. The plasma is discarded and the red blood cells are returned to the body with fewer antibodies (which live in plasma).

Molly and Bethany discuss the when and how of intrauterine blood transfusions (IUTs). Bethany, possibly the world record holder for number of IUTs, has had 16 IUTs through her four allo affected pregnancies. IUTs come with their own risks, but in the hand of a trained and experienced doctor they are the most effective way to maintain the health of an anemic baby.

Episode themes: 

• Likelihood of needing an IUT
• When to perform an IUT (before hydrops is present)
• IUT procedure before, during and after
• Medications used during an IUT
• Spacing of IUTs when multiple are required
• Outcomes of IUTs in a skilled facility
• Tips for patients and clinicians

Questions for your MFM discussed in this episode: 

• How many IUTs do you do per year?
• How often do you do them?
• How many did you do last year?
• What is your success rate?
• Have you ever lost a baby to the procedure?
  • How many?
• Do you perform the IUT in an operating room?
• Do you provide mom with conscious sedation?
• Do you paralyze the baby for the IUT?
• Walk me through the procedure
• What does the monitoring look like after the IUT is finished?
• What do you use to decide when to space IUT?
• When do you do the last one in general?
• How early have you done them?
• Are you willing to refer me to a different MFM for IUTs if necessary? 

Other Tips

• Have a friend or partner there with you when you get an IUT. 
• Communicate constantly with your nurses, doctors, and anesthesiologist 
  • Communicate needs and anxieties
• Speak up about your needs and comfort 
• Ask for and record the beginning and ending hematocrit 

Allo Hope Terminology Library https://allohopefoundation.org/library/terminology/

• IUT: Intrauterine transfusion: using a needle through the mom’s belly to insert blood into the umbilical cord or abdomen of an anemic fetus. 
• Cordocentesis: a test done during the IUT process that determines that a fetus is definitely anemic before transfusing blood. 
• Ascites: fluid collecting in the abdomen of a fetus, a sign of fetal hydrops. This is a sign of critical distress and blood should not be infused into the abdomen. 
• IVT: Intravascular transfer: an IUT where the blood is transferred into the umbilical cord vein and therefore directly into the baby’s vascular system, treating the anemia right away. 
• IPT: intraperitoneal transfusion: transferring blood into the abdomen of a baby. Usually reserved for early gestation before an IVT is possible. Blood is later absorbed into the system when the baby needs it. Not to be done when baby shows signs of fetal hydrops.

Bethany and Molly discuss how to monitor an Alloimmunized pregnancy. This is the first step to treating a sensitized pregnancy. Monitoring the antibody titer can indicate when you need MCA Scans, and intrauterine blood transfusions to keep your baby healthy. 

Episode themes: 

• How babies at risk for HDFN are monitored
• Titers (purpose and frequency) 
• MCA Scans and MoM values (purpose and frequency)
• Specific MCA Scan tips
• What’s next after a high MCA scan
• Fetal outcomes and survival rates 

Terminology used in this episode: 

• Antibody Titer: A measure of antibodies in the mom’s blood, indicates threat to a baby who is affected. Antigen negative babies do not need titer monitoring. 
• Critical Titer: A titer level of 16 (or 4 for Kell) that indicates a need for in utero medical treatments. Remember, once you hit critical levels in a pregnancy you are considered always critical for each subsequent pregnancy and should start MCA scans at 15 weeks in that and each subsequent pregnancy. 
• MCA Scan:  (Middle Cerebral Artery Doppler Scan)  Special ultrasound often only used after a critical titer is detected. Scans the blood flow in the middle cerebral artery of the fetus. 
• MoM: (Multiple of the Median score) the final measurement of an MCA scan divided by gestational age of fetus. Scores of 1 are ideal, scores of 1.5 or higher indicate moderate to severe anemia and a need for intervention.
• Hematocrit: a score detected during a cordocentesis (blood drawn from the cord) to determine the red blood cell volume in the blood.  The normal hematocrit range for infants 0-6 months is 37.4 - 55.9% for females, and 43.4 - 56.1% for males. A fetal hematocrit of less than 30% is considered anemia. Cordocentesis tests can start at 15 weeks.

Testing is the first step toward having a safe and healthy HDFN baby. This episode covers the importance of early tests that can determine how severely your baby will be affected by your antibodies. We include information about new tests, Rhogam, and how you can donate plasma to help other expectant mothers determine the antigen status of their babies. 

Episode themes: 

• Standard pregnancy screening for antibodies
• Antibody ID and titer blood test 
• Blood tests for baby’s father
• Cell free fetal DNA (cffDNA) for baby’s antigen status
• Rh Immune Globulin (Rhogam)

• Antibody ID: followup screen on the mother that identifies what type of antibody the mother has
• Titer: test (and term often used to describe measurement) of the amount of antibodies present in the mother’s blood 
• Critical Titer: Kell 4, All others 16 
• Antigen Phenotype test: Test for the father to determine antigen that baby may inherit 
• Amniocentesis: drawing amniotic fluid by piercing the amniotic sack with a needle through the mother’s belly, can cause antibody titer to go up 
• MCA Doppler Scan: advanced non-invasive scanning technique used to determine fetal anemia 
• Cell Free Fetal DNA Testing: a test using the mom’s blood to determine baby’s blood type, not readily available in the United States. Can be used to detect D, Kell, E, c, and C antigen status.

Welcome to the Allo Podcast! This episode introduces our hosts, Bethany and Molly, our recurring guests from our Medical Advisory Board, the Allo Hope Foundation, and most importantly the diseases known as Maternal Alloimmunization and Hemolytic Disease of the Fetus and Newborn. Get the quick facts on how to monitor and treat this disease and how Bethany, Molly, and so many moms have used these treatments to deliver healthy babies. 

Episode themes: 

• Alloimmunization overview
• What to expect in an allo pregnancy
• How HDFN affects the baby
• How allo moms can protect themselves and their baby

Terminology used in this episode: 

• Alloimmunization: a disease in which a mother’s antibodies are primed to attack an incompatible blood antigen that may be present in the blood of their fetus.
• Hemolytic disease of the fetus and newborn (HDFN): a blood disorder in a fetus or newborn that develops when the pregnant mother’s antibodies pass through the placenta during pregnancy and attack the baby's red blood cells, breaking down the baby’s red blood cells (hemolysis) at a rapid rate and causing the baby to become anemic.
