Nevertheless, I think your focus on medical genetics is quite misguided. For example, we know several causes of recurrent stillbirth and infant death that are not genetic in nature. For example, NAIT certainly has a genetic predisposition, but the primary treatment is immune and hematologic in nature. There's no reason this would fall under a geneticists area of expertise, and given the rarity, it's not clear most OBs would know about it either. Several couples I've met in online support groups have had a lot of trouble finding a doctor knowledgeable enough in NAIT to properly treat their pregnancies (which are actually remarkably successful, when treatde). Given the importance that we ought to be giving to lives of young children, it seems that simply lumping known non-genetic causes with genetics is the wrong approach. A better approach -- in my admittedly biased opinion -- would be to have one specialty with a wide breadth of knowledge who could specialize in teasing out what may be causing any particular issue.
For example, it seems somewhat ludicrous to believe that a woman who loses several babies consecutively in the third trimester due to premature labor while the baby is still alive is being affected by the same pathology that causes another woman's babies' hearts to just keep stopping. Unfortunately, these distinctions are rarely made in studies.
And while OBs are the ones on the front-line of treatment, they're also mainly a surgical / low-risk specialty. There does need to be some specialized care for the higher-risk couples. Multiple studies in other countries (we're in America) have shown that simple supportive care (including heavy monitoring, constant reassurance, and dedicated clinics) increases the live birth rate in couples with recurrent stillbirth or other forms of pregnancy loss.
We live in the bay area, we have managed to make appointments with several specialized doctors, including the department chair of obstetrics and gynecology at one of the large academic hospitals here (after much consternation with the nurses on the phone). They have told us that they do not know. She also told us that she's never really seen too many cases of sudden cardiac arrest in mid-pregnancy fetuses. She did not send us to anyone else -- believe me, my wife and I would hop on the opportunity to find another doctor with relevant experience.
I’m gonna leave it at this: if you’re willing to take a trip, NYU has a dedicated repeat pregnancy loss center (Phone: 212-263-6359).
(And for what ever a strangers internet words are worth: I do earnestly hope that they or someone else succeeds in helping you.)
(I want to echo the good vibes here, too.)
Perhaps I haven't made my complaint clear. The doctors exist, but they aren't helpful.
We don't expect miracle answers, and realize medicine may not know, but it would be nice to have a dedicated clinic to work with you through it, or at least a doctor willing to establish a long-term relationship. I expect it would also help researchers formulate new hypotheses if they kept in contact with couples who are 'unexplained'.
We have been to three recurrent loss clinics at UCSF, Stanford, and the Mayo Clinic. There are doctors there who do research in this area, but if you don't have any of the limited number of conditions that they know about, they aren't helpful, nor are they willing to help you find clinical trials that may apply or willing to explore research with you or stick with you. I've read many brochures and websites that claim that the doctors will work with you to determine the cause of miscarriage, stillbirth, etc, but in our experience they work with you until they give up, then they don't want to see you anymore.
This is a bit different than other specialties. I don't have much experience with doctors, but I do have some older family members with chronic illnesses, a few with rare, unexplainable ones. In that situation, it's common for doctors to establish long-term relationships with patients and suggest clinical trials or research opportunities they can participate in. The approach seems different than what we've seen.
Once we're done with our next round of appointments, perhaps I'll call NYU. We have a few more appointments coming up with some more research doctors; hopefully, they will be more willing to keep track of our case.
