Emilie and Mathilde are the reason that TAPS Supports exists. Stephanie, Emilie and Mathilde’s story is just one of many TAPS stories out there. Theirs is one of the happy ones – and it’s all down to getting the right care and treatment.
Read their story now and share to spread Stephanie’s message of hope. Like Stephanie says:
“That’s why sharing our stories is important – we may all be rare – but we can shout loudly together.”
(Of course, along with the shock and disbelief of Oh my god, we’re having twins! I mean, finding out you’re having twins can be a real shock to your system!)
Our twins were monochorionic, diamniotic – identical twins that share a placenta but have separate amniotic sacs. Because they shared a placenta, we were at increased risk of complications like Twin-Twin Transfusion Syndrome (TTTS).
Things were progressing well, and I had a relatively complication-free pregnancy, even with some hiccups like severe morning sickness. At 20 weeks, we found out we were having girls and began preparing our lives as a future family of 4.
23 Weeks Pregnant
But this should have triggered my brain to go to the doctor.
This was devastating, as both conditions are rare, and to be diagnosed with both in one day was terrifying. Treatment options were presented to us, but we were so overwhelmed with all the information that we opted to come back the following day to discuss our options.
It was honestly the most scared and vulnerable I’d ever felt. I found much information online about TTTS, but it conflicted with what my doctors told me. I could not find any info about TAPS that was easy to read – it was more of a subheading in some places, and all of it was either in medical journals or another language. This was confusing and scary.
The team I saw was reassuring, and I felt confident in their care. We opted to take the option of close monitoring every couple of days, and this saw things stay stable. Our TTTS diagnosis stabilised and eventually was dismissed as we were one of the rare cases where it resolved itself.
However, the suspicion of TAPS stayed and became our primary diagnosis.
What Is TAPS?
Twin Anemia Polycythemia Sequence is a rare disease affecting twins who share a placenta. (There are rare exceptions to this). It affects around 3-5% of these twins, but we don’t know how accurate this statistic is, as it is not routinely screened for worldwide.
TAPS is caused by tiny connections in the placenta, less than a millimetre thick. These connections go in one direction. The donor baby sends only red blood cells to their twin sibling, causing chronic anemia. The recipient baby’s blood becomes thick and difficult to pump around. This is called polycythemia.
Diagnosing TAPS is difficult. In TTTS, the fluid differences, as well as symptoms for the parent, such as feeling heavy, or big, or a tight feeling in the stomach, rapid weight gain, and a lack of movement from the babies. Ultrasound will show the significant differences between the fluids of the babies – with one baby having less than 2 centimetres of fluid and the other having excess fluid.
(Note, staging TTTS has some controversy. While it’s generally accepted that more than 8 centimetres of fluid) in the recipient twin makes stage one (Quintero staging); across the UK and Europe, after 20 weeks, TTTS is sometimes diagnosed when the recipient has 10cm or more of fluid (Eurofetus trial). Neither are wrong; what matters is monitoring and treatments!)
This test is controversial; unfortunately, many countries do not routinely screen for TAPS. The reason is that there is currently no best treatment for TAPS, so management options are unclear. However, there are treatment options available, like laser surgery (they draw a line across the placenta with a laser to stop any connections between the twins), inutero blood transfusions, early delivery, and, like me, a watch and wait approach is absolutely possible. TAPS moves slowly, so it’s possible to closely monitor it.
There is also the reason used that they’ll see signs on ultrasound. There are signs on ultrasound, but not always. MCA doppler is the most reliable and accurate way to detect TAPS.
The long-term effects of TAPS are also concerning. 1 in 8 donor twins is born profoundly deaf due to Auditory Neuropath Spectrum Disorder (ANSD), and donors are also four times more likely than recipients to have developmental and cognitive delays. Both twins are at risk of neurodevelopmental impairment. It’s a serious disease with severe long-term outcomes, so screening is essential.
Back To The Story
At 30 weeks, I went for my regular checkup, and the news changed from stable to concerning. One of the rarer complications of polycythemia is that blood clots can form in the recipient. There were worrying signs on the ultrasound of the brain of my recipient, and the decision was made to deliver my girls.
At the time, no one could tell us our girls’ long-term outcomes, but we were reassured that as research continued, we’d be updated.
As our girls grew, we knew things weren’t quite going well with their development, and we repeatedly raised concerns. But we were always brushed off – it’s nothing to worry about.
The girls were around 5 years old when we received more information about TAPS’ long-term outcomes, and we started advocating for further testing. At age 7, they were diagnosed with autism and Developmental Coordination Disorder (DCD). We fell in line with the neurological outcomes for TAPS. Still, it took a lot of advocacy and pushing the system to get the diagnoses.
Starting a Foundation
Since we started 2 years ago, we’ve successfully completed a few projects, funded research into donor twins at birth, and even presented on our incredible partnership with the research team who diagnosed me all those years ago at ECRD2022.
That’s why sharing our stories is important – we may all be rare – but we can shout loudly together.
