How can a successful pregnancy occur after recurrent miscarriages?

During this webinar, Dr Ksenia Khazhylenko, Obstetrician-gynecologist, Fertility Specialist & Geneticist at IVMED – Fertility Center talked about 2 of her past patients who experienced recurrent miscarriages and were able to finally achieve their final goal – a healthy baby.

How can a successful pregnancy occur after recurrent miscarriages? - Questions and Answers

What is the most common problem that miscarriage patients face?

It all depends on the term of pregnancy. In early pregnancy, the most common problem is chromosomal pathology, but if we are talking about late-term miscarriage, it is 22 weeks of pregnancy here in Ukraine, it’s more about blood clotting problems. In the middle of these terms, we are talking about uterine issues, endometrial abnormality, chronic endometritis, and also shortening of the cervix, which usually starts from 14-16 weeks of pregnancy. These are the most common reasons.

When we are talking about 20 to 24 weeks of pregnancy, it’s not a miscarriage, it’s pregnancy loss, there are many different causes for this.

I’m 36, I had 5 miscarriages in early pregnancy ( 5-6 weeks of pregnancy), all were the result of IUI. All tests ( karyotype, genetic testing, hormones, etc.) were done, and there is nothing to prove why is this happening. Any advice?

When we are talking about karyotyping, it doesn’t give us extensive information because chromosomal pathology in embryos mostly happens during conception, when sperm fertilizes the eggs. In the majority of cases with chromosomal pathology in the embryo, the parents have a normal karyotype, but a normal karyotype doesn’t mean that you didn’t have a problem with the chromosome. Therefore, chromosomal pathology seems realistic in this situation.

It would be better to discuss this with the patient, there are 2 ways, IVF program with PGT-A or natural conception. There are a lot of so-called immunological tests, but these tests are not yet evidence-based. IVF with PGT-A, in this case, can be very helpful even if the reason for the miscarriages was not because of chromosomal pathology. When we provide genetic testing of the embryo, we can explain the prognosis for you, and we can find out the reason for the previous situations because we know how many normal and abnormal embryos we normally have for each specific age group.

If the result, let’s say is in the middle of normal and abnormal embryos typical for this age, it means that the previous miscarriages were not caused by chromosomal pathology and we need to continue and look for something else, maybe there are some immunological problems, blood clotting problems and so on.

What about chronic endometritis?

Chronic endometritis in a patient with RPL is different from the infertility patient group. When we learn that the patient has chronic endometritis after miscarriage, we never know if the reason was the condition or because of miscarriage. Chronic endometritis is not just inflammation, it means there are changes in endometrium sometimes with micro polyps, sometimes with polyps, sometimes with uterine adhesions. If after treating endometritis, we see some changes in the endometrium on an ultrasound, it is better to do a hysteroscopy.

If there are no signs of endometrial pathology on ultrasound, we just need to treat it. Then I recommend checking it to make sure that we have treated endometritis, so perform a biopsy of endometrium a month or two months after the treatment.

After treating chronic endometriosis, at least 10% of the patients will have positive results again. The main question is: What to do with this patient? There is no international recommendation for this situation. When the second tests are positive, it’s hard to offer any recommendations.
For patients who are undergoing an IVF program, the answer is much easier. In such patients, we can use some medications to kind of turn off the menstrual bleeding for 1 to 3 months.

One of the main reasons for chronic endometritis recurrence is uterine bleeding every month, and this is possibly a reason for the recurrence of inflammation of the endometrium. In such a case, when we plan embryo transfer, we can use different medications, stop the bleeding for 1-3 months and then do embryo transfer. This is usually a strategy that is effective enough.

I am 40, in my second attempt, I had a failed implantation via PICSI. I have high NK cells. Any advice?

It’s important to know if your embryos have been genetically tested. Usually, we talk about NK cells in fertility programs where the patients already had checked their embryos genetically. If they are not tested, we don’t know the chromosomal status of the embryos, it’s not a good idea to focus only on NK cells. If they are genetically tested, there are a lot of ways that we can check it, but as I have mentioned, it’s not evidence-based at this moment.

I don’t have enough information, and there are different types of treatment, NK cells are 70% of all immune cells in the endometrium, you need to do some additional tests to study different parts of the immune system in the endometrium, in the blood.

For a high level of NK cells, we can use intralipid infusions, which is the most popular method nowadays. It’s very effective, and this was a very low possibility of side effects, so this is the most popular treatment of high-NK cell levels. Keep in mind that it can be about different immunological disorders, the first, and most important would be the genetic status of all the embryos.

How useful is checking thrombophilias and anti-phospholipid antibodies in cases of RPL?

It’s strongly recommended to check antiphospholipid antibodies for RPL patients at any term of pregnancy losses. There is a strong association between antiphospholipid syndrome and recurrent miscarriages.

Regarding thrombophilia, it’s a bit different. There is not enough proof for the association between thrombophilia and the risk of pregnancy.
When we test the patient for thrombophilia, it’s not about the real risk for the pregnancy, it’s about general risk. Thrombophilia testing was performed for patients whose relatives had thrombotic events. For those patients, thrombophilia risk means just having an additional higher risk of thrombotic events in the future.

For RPL patients, it’s a bit different. Looking at my first case, Victoria was tested for thrombophilia, the result was that she had a middle risk of mutation, but she had other risks, antiphospholipid antibodies, she was a smoker, this is an additional risk for the thrombosis, she had a family risk of thrombotic imbalance from relatives of the first degree. It means that even if she doesn’t have any thrombophilia mutation, she has enough thrombotic risk, therefore it’s better to double-check it.

Thrombophilia risk means that this patient has a bit higher risk of thrombotic events during her life, but it doesn’t mean that it was the reason for recurrent miscarriage or any miscarriages. Fortunately, approximately, 95% of all patients with mutations don’t have any thrombotic events during their life. Fortunately, 95% of all patients don’t need this test.

I see patients in my practice during my consultation where they had 3 or 5 miscarriages, and after a second miscarriage, they were performing different tests, and they were positive for some thrombophilia mutation. Then during the 3rd or 5th miscarriage, she was still unsuccessfully treated with heparin, and she had a miscarriage anyway. The reason was different, so testing for thrombophilia is not obligatory, it’s not helpful.
