Dexamethasone

As a follow-up to a previous post in March concerning CAH - congenital adrenal hyperplasia.

From TIME :
Langford and her husband learned they were silent carriers of the genetic variation that causes CAH when their son was diagnosed with the condition after birth. Their son — like the 1 in 16,000 babies born with CAH each year in the U.S. — faces a lifetime of taking powerful steroid medications to compensate for his faulty adrenal glands. When Langford contacted New about her second pregnancy, New, who was not Langford's regular doctor, called a local pediatric endocrinologist. That doctor prescribed Langford a commonly used medication for CAH. "Dr. New told me I had to start taking dexamethasone immediately," says Langford, 30, who lives in Tampa. "We felt very confident in someone of her stature and that what she was telling us was the right thing to do."
...
The early prenatal use of dexamethasone, or dex, has been shown to prevent some of the symptoms of CAH in girls, namely ambiguous genitalia. Because the condition causes overproduction of male hormones in the womb, girls who are affected tend to have genitals that look more male than female, though internal sex organs are normal.
...
Langford says also that neither New nor her prescribing physician mentioned that prenatal dexamethasone treatment is an off-label use of the drug (an application for which it was not specifically approved by the government) or that the medical community is sharply divided over whether dexamethasone should be used during pregnancy at all.
And now a series of articles from Bioethics. First, Preventing Homosexuality (and Uppity Women) in the Womb?:
The majority of researchers and clinicians interested in the use of prenatal “dex” focus on preventing development of ambiguous genitalia in girls with CAH. CAH results in an excess of androgens prenatally, and this can lead to a “masculinizing” of a female fetus’s genitals. One group of researchers, however, seems to be suggesting that prenatal dex also might prevent affected girls from turning out to be homosexual or bisexual.

Pediatric endocrinologist Maria New, of Mount Sinai School of Medicine and Florida International University, and her long-time collaborator, psychologist Heino F. L. Meyer-Bahlburg, of Columbia University, have been tracing evidence for the influence of prenatal androgens in sexual orientation. In a paper entitled “Sexual Orientation in Women with Classical or Non-Classical Congenital Adrenal Hyperplasia as a Function of Degree of Prenatal Androgen Excess” published in 2008 in Archives of Sexual Behavior, Meyer-Bahlburg and New (with two others) gather evidence of “a dose-response relationship of androgens with sexual orientation” through a study of women with various forms of CAH.

They specifically point to reasons to believe that it is prenatal androgens that have an impact on the development of sexual orientation. The authors write,
"Most women were heterosexual, but the rates of bisexual and homosexual orientation were increased above controls . . . and correlated with the degree of prenatal androgenization.”

They go on to suggest that the work might offer some insight into the influence of prenatal hormones on the development of sexual orientation in general. “That this may apply also to sexual orientation in at least a subgroup of women is suggested by the fact that earlier research has repeatedly shown that about one-third of homosexual women have (modestly) increased levels of androgens.” They “conclude that the findings support a sexual-differentiation perspective involving prenatal androgens on the development of sexual orientation.”

And it isn’t just that many women with CAH have a lower interest, compared to other women, in having sex with men. In another paper entitled “What Causes Low Rates of Child-Bearing in Congenital Adrenal Hyperplasia?” Meyer-Bahlburg writes that “CAH women as a group have a lower interest than controls in getting married and performing the traditional child-care/housewife role. As children, they show an unusually low interest in engaging in maternal play with baby dolls, and their interest in caring for infants, the frequency of daydreams or fantasies of pregnancy and motherhood, or the expressed wish of experiencing pregnancy and having children of their own appear to be relatively low in all age groups.”

In the same article, Meyer-Bahlburg suggests that treatments with prenatal dexamethasone might cause these girls’ behavior to be closer to the expectation of heterosexual norms: “Long term follow-up studies of the behavioral outcome will show whether dexamethasone treatment also prevents the effects of prenatal androgens on brain and behavior.”

In a paper published just this year in the Annals of the New York Academy of Sciences, New and her colleague, pediatric endocrinologist Saroj Nimkarn of Weill Cornell Medical College, go further, constructing low interest in babies and men – and even interest in what they consider to be men’s occupations and games – as “abnormal,” and potentially preventable with prenatal dex:

“Gender-related behaviors, namely childhood play, peer association, career and leisure time preferences in adolescence and adulthood, maternalism, aggression, and sexual orientation become masculinized in 46,XX girls and women with 21OHD deficiency [CAH]. These abnormalities have been attributed to the effects of excessive prenatal androgen levels on the sexual differentiation of the brain and later on behavior.” Nimkarn and New continue: “We anticipate that prenatal dexamethasone therapy will reduce the well-documented behavioral masculinization . . .”
Now, from Prenatal Dex: Update and Omnibus Reply :
It appears that in the vast majority of cases, New did not enroll these women in an IRB-approved treatment trial of prenatal dex. Indeed, in spite of many admonitions from colleagues to undertake this risky, experimental treatment only under IRB oversight (if at all), New seems for many years to have promoted the off-label use of this Class C drug to pregnant women as safe and effective, and to have simultaneously sought and obtained NIH funding to study these women and children after birth to see if the drug was, in fact, safe and effective. (The follow-up studies have had IRB approval, but those overseeing the follow-up studies should have been asking where all these exposed subjects were coming from.) The American Academy of Pediatrics, the European Society for Pediatric Endocrinology, and the Lawson Wilkins Pediatrics Endocrine Society have been among those specifically arguing that this powerful steroid should not be employed for this use outside IRB-approved prospective studies.

In February, 32 researchers in bioethics and allied disciplines signed letters of concern to New’s institutions, to the FDA Office of Pediatric Therapeutics, and to the HHS Office for Human Research Protections.
...
Studies of prenatal dexamethasone give us substantial reason for concern for these mothers' and children's physical and mental well-being, particularly given that this usage is aimed at preventing a cosmetic issue (one not shown to increase psychosocial risk) and that 87.5% of the mothers started on prenatal dexamethasone will not even be carrying a fetus that is 46,XX 21-hydroxylase deficient. Studies have already shown some adverse effects on exposed children.[5,24,25] In addition, some researchers have raised concerns about possible epigenetic effects that might even impact these children's children's well-being.[25]

We do not find evidence that animal studies have shown that prenatal dexamethasone is likely to be safe in humans; on the contrary, studies showing harm to animals exposed prenatally to dexamethasone have been used by the teams associated with New to try to figure out what defects they might find in the exposed children.[9] This certainly looks to us like an improper move to human experimentation on pregnant women of a Class C steroid without satisfactory establishment of safety in animal studies. That this human experimentation may even be done without IRB oversight astonishes us.

From the letter to Lawson Wilson Pediatric Endocrine Society mentioned above:

Treatment to prevent physical Intersex symptoms which can cause serious problems such as vaginal fistulae is, absent any side-effects, a worthy goal. From BigThink :
An enlarged clitoris is one common feature of masculinization. However, the effects can be far more serious and affect not merely the girl's appearance, or even her gender presentation, but the health and functionality of her entire genitourinary tract.

In severe cases, the vagina and the urethra may open into a common sinus, instead of being separate tubes. Surgery may be required to create separate vaginal and urethral openings. Otherwise, urine can flow into the vagina, which creates an indirect kind of incontinence when it dribbles out again. Urine in the vagina can also cause chronic irritation and increase the risk of vaginal infections.

Sometimes the vaginal canal isn't wide enough to carry menstrual blood out of the body, in which case, surgery is required. Unfortunately, reconstructed vaginas tend to narrow over time. So, the patient may have to undergo still more surgery and/or months of painful training with dilators to stretch her vagina enough to have intercourse.
Treatment to "normalise" functional genitalia is more controversial, but I think most would approve of it, again absent any side effects. Some Intersexed people may differ on that, just the way many hearing-impaired people might not see congenital deafness as an undesirable defect, but a mere variation, a difference. I think though that this is a distinctly minority view, and that informed parental choice should have a role here, rather than a directive from those not personally involved. There is an argument against such therapy, and even if I personally think it's weak, I see no great harm in not having treatment should Society be moderately sane about it.

Treatment to prevent Transsexuality, again if it had no side effects, is something I would consider even more strongly justified though. Even if Society was sane. Because there could be a substantial mismatch between body-image and somatic form, which can cause immense suffering.

Treatment to make girls bidable, demure, maternal, and above all straight on the other hand... now we're getting into ethically dubious territory. We have to look at the rights of the parent. Are they unfettered? Do we have a right to prevent a parent from having a gay child? Or educating them to be racist, bigoted, even sadistic and sociopathic?

I don't think the rights of a parent should be unfettered. But I also see a distinction between the two cases above. In the second, there is harm not (just) to the child, but to those who they will interact with in their lives. In the first, as medical technology improves and society hopefully gets saner, they will have the same reproductive abilities regardless of whether gay or straight. Choosing sexual orientation for a child is no worse - and no better - than choosing eye colour, or handedness.

Of course the GLB advocacy groups who have remained silent when only Intersexed and Trans kids were experimented on this way, are now having a large economy-sized cow over the subject. Human Nature of course, but still Ironic.

The ethical issues are moot though. Because all of the above is predicated on there being no adverse consequences. And that is something that we are not only not sure of, we have reason to believe is not true.

From a comment by Faith over at Joe.My.God:
The risks are common risks of corticosteroid therapy, and, in some cases the benefits outweigh the risks, such as in the case of underdeveloped lungs -- however, if the risk is that the child will be less likely to play with dolls or want to make babies the risk/benefit ratio does not pan out. No IRB in their right mind would approve this study and she is not doing it under the purview of an IRB. Incredible.

And from Kirstin:
So I found and read the list of side effects. And, while reading them I kept in mind that this drug was being or going to be delivered to developing fetuses... These side effects have been reported and are happening to already born humans. Can you imagine submitting a developing fetus to something that can and has caused anything off the list below?

There's rather more, at Psychology Today, at ScienceBlogs and elsewhere. Including this comment:
Aaaargh.

Some things about me fit into stereotypical gender roles. (I'm a cisgendered, heterosexual woman.) Some don't.

I'm happily married to a man and do eventually want kids. I have good verbal and emotional skills, I prefer collaboration to argument, I like to cook and bake, I like to knit, I like kittens, and sometimes I enjoy putting on femme costume (dresses, heels, makeup, jewelry).

But: I proposed to my now-husband. I majored in physics (where I was the only woman), I have an M.S. and am working on a Ph.D in biomedical engineering (so I also have good logical/mathematical skills), and deferred kids to prioritize that education. In fact, I wasn't sure I wanted kids at all until recently. I'm very good at coding, I dislike and avoid cleaning, I like using power tools of all kinds, I like building things, I like comic books, I like lifting weights, and I usually dress in non-ornamental t-shirts and jeans without makeup -- I'd be miserable having to dress and groom super-femme all the time, though I have fun with doing it occasionally. I particularly enjoy doing coded-masculine things while dressed/groomed in a more-femme way, just to mess with people.

In short, I'm a human being, with varied skills, interests, likes and dislikes. Gender essentialism is a load of BS.
Well, sort of. One possible effect of this therapy is to make women like her extinct. Whether deliberately, a bug or a feature, I think it likely that it would.

I don't think that would be a good thing. Some do.

The worst thing from a scientific viewpoint - after doing the Mengele act, telling pregnant women - and not just a few, but hundreds - that the drug was proven safe (when we have good reason to believe that is not the case) - the follow-up on the effects has been slipshod too. So much so that it's possible the findings were not to their liking, and they concealed them to avoid lawsuits.

It's been six years since Dr New last prescribed this drug. The first patients - though it's possible that the word "victims" might be accurate, and "experimental subjects" more accurate still - will be 11 years old now. Old enough for us to see many of the effects on psychology, and virtually all on non-neurological anatomy. I hope we're lucky, and my fears groundless.

Because she's playing with fire in an explosives factory. As Alice Dreger said in her article in Psychology Today:
This drug is unequivocally experimental and risky. That's why, back in February, I organized interested members of the Bioethics community to fight to make sure every woman offered dex for CAH knows the truth about its experimental and risky nature. (You can read about our efforts in Time magazine. And you can about the medical establishment's resultant mad scampering to make sure everyone knows this is experimental here.) Make no mistake: In spite of Dr. Maria New's outrageous FDA-regulation-flaunting claims that this off-label drug use "has been found safe for mother and child," it ain't been. New is a rogue pediatrician whom medical societies have been nudging (and sometimes yelling at) for years. Because she apparently wouldn't stop experimenting on these women and children without ethics oversight, in January I got called in to help by a few freaked-out clinicians. And I called in my colleagues to call out the feds. New just looks and sounds safe for mothers and children. Which is why she's really dangerous.
It's the height of Irony that Ms Dreger is one of the greatest supporters of Michael Bailey. Someone infamous for ignoring neuro-anatomy as a factor in transsexuality, and who insists that all trans women are actually deceptive gay or sexually perverse men. And someone who thinks it just fine and dandy that "teh gay" be prevented by pre-natal intervention.

Hi Zoe,

you wrote:

"Treatment to prevent Transsexuality, again if it had no side effects, is something I would consider even more strongly justified though. Even if Society was sane. Because there could be a substantial mismatch between body-image and somatic form, which can cause immense suffering."

from Alice's last article in the Hastings Center Bioethics forum:

"New’s “paradigm for prenatal diagnosis and treatment” suggests a reason why activists for gay and lesbian rights should be wary of believing that claims for the innateness of homosexuality will lead to liberation. Evidence that homosexual orientation is inborn could, instead, very well lead to new means of pathologization and prevention, as it seems to be in the case we’ve been tracking"

Read more: http://www.thehastingscenter.org/Bioethicsforum/Post.aspx?id=4754&blogid=140#ixzz0saTwwjAD

and then this on Dorner's work:

"Dörner et al. even advocated altering the hormonal environment of the fetus. These researchers made it quite clear that they were attempting to eradicate homosexuality. Earlier, Dörner stated,

It was concluded from these data that... it might become possible in the future -- at least in some cases -- to correct abnormal sex hormone levels during brain differentiation in order to prevent the development of homosexuality. However, this should be done, if et al., only if it is urgently desired by the pregnant mother.

Researchers at the Psychiatric Institute in New York also work toward identifying the prenatal hormonal influences on sexual orientation and gender behavior, although they reject the use of this information to alter sexual orientation."

And this about Steinach:

"Steinach in 1917 was the first to use a surgical technique to attempt to cure homosexuality. First, he performed a unilateral castration on a homosexual man, then transplanted testicular tissue from a heterosexual man into the castrated patient. He did this in the belief, prevalent in those times, that homosexuality was a form of hermaphrodism. Steinach was in step with the belief that homosexuality represents a "third sex," and idea originated by Ulrichs and popularized by Hirschfeld. At least 11 men were operated on from 1916 to 1921. Complete castration was not performed in the belief that after transplantation of the "normal" testicular tissue, the man would be cured, married, father children, and lead a heterosexual life. The experiments were a failure."

I am someone from a country that has no universal health care. If you don't have the money or the insurance to cover a procedure, you don't get the treatment. As a woman of transsexual history, I often wonder how my life would be different if I had the masculinizing genital surgery I was told I needed as an adolescent. I know others who did have surgeries that were somewhat similar to the procedure or procedures as it was explained to me, but not very clearly, that the doctors intended to do. The two people I know who did have the procedures performed are very angry about what happened to them.

The caveat issued by Dreger is not lost on me. I think it is why a lot of people object to the search for a definitive neurological link to transsexualism. Personally, I do believe there are neurological links but I think the reasons are unique to the individual for the most part. I have to ask why you seem to be encouraging the kind of quackery that has persisted in society's attempts to normalize people. I strongly object to comparisons involving obvious physical disabilities to the phenomena of transsexualism, intersex and sexual orientation.

Examining Silverstein's quote at the end of what he has to say about Dorner, I am reminded of what Ken Zucker and the rest of the staff at the CAMH attempt to do when it comes to "gender behavior":

Edith -
As a woman of transsexual history, I often wonder how my life would be different if I had the masculinizing genital surgery I was told I needed as an adolescent.

So why did you tell them you were male?

Because if you didn't - how come they thought you needed it?

We both know the answer.

I put it down to ignorance though.

The more we know, the more power we have. It's up to all of us to make sure that power is not misused. Remaining ignorant makes things worse though, not better.

edith said...

You kind of lost me here, Zoe. All I can say is, I was told I was male, although many implied I wasn't really. I gradually awakened to the fact that I wasn't. Switching to the female role was an easy process. Then came the medical treatment that helped relieve a lot of tension. I don't put a lot of stock in notions of rigid gender identities. Clearly, living as a male was not working for so many different reasons. Living as female is a much better fit that seems mechanical, fit being the operative word. Nothing is perfect but I wouldn't want to be anybody except for the person I am.

Anne Rose Blayk said...

When it comes to Dr. Dreger, I'm not really sure what's going on... but it doesn't look good to me.

Item: "Yesterday, Dr. Alice Dreger had an Op-Ed published criticizing women who, by their strenuous opposition, evidently derailed the appointment of Dr. Lawrence Summers as Secretary of the Treasury. They characterizing him as a 'sexist' because he had described the failure of women to attain higher positions in academia as the result of lesser ambition and innate talent, rather than discrimination. According to Dr. Dreger, 'These women are only objecting to Dr. Summer's appointment out of narcissistic rage in response to the narcissistic injury they feel in response to Dr. Summer's clear exposition of the facts refuting their belief in the 'Feminine Competence Narrative'; they are incapable of accepting that their interest in microbes, rocketry, or particle theory is merely an expression of a paraphilic obsession with themselves as scientists, when in fact 90% of them will never be able to pass successfully as scientists.'"

Oops! That one came from an alternate universe! Sorry!

It appears that she has a bias that's relevant to transsexuals here... I'm not going to dignify her deployment of the swear-word "anti-democratic" as founded on a "value", since I have little use for elitists (physicians or not, bioethicists or not) who appoint themselves as Ethics Guardians for Unaccredited Folk who Just Don't Get It.

To Have Is To Hold:

"A democratic medical establishment does not alter people's bodies to fit regressive social norms; it advocates for patients by demanding the social body get its act together. As a white woman who grew up with a black brother, I can tell you that the solution to my brother's suffering was not to have his skin bleached and his hair straightened, prenatally or postnatally."

...

"3. Trying to prevent homosexuality in the womb is akin to cosmetic "medical" procedures in that it is inherently anti-democratic. I've ranted elsewhere about why medicine needs to be liberated from recent profoundly anti-democratic trends"...

"ranted elsewhere"... what is this "profoundly anti-democratic trend"? ... see Medicine Needs a Declaration of Independence from Cosmetic Procedures:

"... “cosmetic medicine” represents a corruption of the core principles of both medicine and democracy."

And here's a really weird statement from Dreger:

Informed Dissent:

"For dissent to be effective, for it to be sustainable, for it to be ethical, it has to be factually right." [Dreger's emphasis]

Wow... what a profoundly illiberal attitude. People have the right to dissent even if they're dishevelled, incoherent, and obviously wrong... dissenting would only be "unethical" if they lied about their beliefs. I wonder how much this profoundly anti-democratic belief influenced Dreger in her "history" on the BBL controversy... ?

(Anyway, to address the main point here, where Dreger has it right: shame, shame, shame.)

Valerie Keefe said...

I can't possibly agree with you that we should try to prophylactically prevent transsexuality. The vast majority of the pain I experienced was not from the initial dysphoria, but the inability to remedy it.

Dysphoria itself, if temporary and easily ended, has to be one of the most validating experiences I can name. I know who I am and what I have because of how WRONG it cumulatively felt to pretend otherwise. I wish everyone could have a year of that, without the residual existential distress caused by feeling one's body is marked for life.
