What would you propose in general and
would you modify the treatment ?

PTU was historically preferred over MMI (especially in the US), with the rationale that the former was more water soluble and more extensively bound to albumin than MMI (limiting the trans-placental passage)
– this seems however to be unlikely …

Side-effects of ATD in pregnancy
‘MMI embryopathy’ includes aplasia cutis and choanal or esophageal atresia
– Aplasia cutis is the absence of skin and accessory structures over the scalp.
Skin defects are estimated to occur in 1 out of ~4,000 to ~10,000 pregnancies and, from the scarce data available, it is considered that this incidence is not above background in pregnant women who have received MMI.
– Choanal or esophageal atresia is a severe congenital anomaly requiring
major surgery to repair and is considered to have a higher incidence than expected in fetuses exposed to MMI in the first trimester. The relative risk of choanal atresia in pregnant women receiving MMI was estimated to be ~17-fold greater than in the general population, although it should be noted that such congenital birth defects could also be attributed to thyrotoxicosis per se rather than to the administration of MMI.

- Available evidence suggests that MMI may be associated with congenital
anomalies, PTU should be used as a first line drug especially during 1st
trimester’s organogenesis.
- MMI may be prescribed if PTU is not available, or in case of intolerance
- T4 is not recommended with ATD during pregnancy

• With regard to PTU, a controversy has recently come to light following the
alarming report that the use of PTU for treatment of pediatric GD was
associated with a significant risk of liver failure
– the Endocrine Society recommended that PTU stopped being used in the
pediatric population.
In the context of the first trimester of pregnancy, however, PTU remains the
drug of choice with a switch to MMI treatment thereafter. Finally, pregnant
women under PTU should monitor their liver function tests regularly.

• Surgery
– may be necessary in women who cannot tolerate thionamides
because of allergy or agranulocytosis or have a huge goiter
• It is however associated with an increased risk of spontaneous
abortion or premature delivery. These risks are minimized by
operating during the second trimester.

TSH-Rec Abs freely cross the placenta and can stimulate the fetal thyroid.
These antibodies should be measured before pregnancy or by the
end of the 2nd trimester in mothers with current GD, or with a history
of GD and treatment with I-131 or thyroidectomy, or with a previous
neonate with GD.
Women who have negative TRAb and do not require ATD have a
very low risk of fetal or neonatal thyroid dysfunction.
131-I should not be given to a woman who is pregnant.
If inadvertently treated, the patient should be promptly informed of
the radiation danger to the fetus, including thyroid destruction if treated
after the 12th week of gestation.

In women with elevated TRAb or in women treated with ATD, fetal ultrasound should
be performed to look for evidence of fetal thyroid dysfunction
- lgrowth restriction, hydrops, presence of goiter or cardiac failure.
Umbilical blood sampling should be considered only if the diagnosis of fetal thyroid
disease is not reasonably certain from the clinical data and if the information gained
would change the treatment.
All newborns of mothers with GD should be evaluated by the medical care
provider for thyroid dysfunction and treated if necessary.

Is Graves-Basedow associated with
an adverse pregnancy outcome ?

Prevalence
• The prevalence of hyperthyroidism has been estimated
to range between 0.1% and 1%
• 0.4% clinical and 0.6% subclinical
– The most common cause is GD (85% of overt hyperthyroidism in pregnant women).
– A second common aetiology is gestational transient
thyrotoxicosis (GTT) or non-autoimmune hyperthyroidism.
• differentiation of GD from GTT is supported by presence of evidence of autoimmunity and/or a goiter

PPT
– Prevalence between 3-17%
• 50 % in women with TPO-Ab
• 25 % in women with DM-1
– Recurrence in subsequent pregnancies (70%)
• The pathologic findings in the two disorders are similar and both are
associated with particular HLA-B and HLA-D haplotypes, suggesting
that inherited risk factors are important.

PREVENTION of PPT ?
– Selenium supplementation may decrease inflammatory activity in pregnant
women with AITD and may reduce the risk of PPT in women who are
positive for TPO-abs.
• This was illustrated in a trial of 151 TPO-positive women randomly assigned to
receive selenium (200 mcg daily) or placebo (beginning at about the 12th week of
gestation). PPT occurred in 22 of 77 women (29 percent) in the selenium group,
compared to 36 of 74 (49 percent) in the placebo group.
– The routine clinical application of this supplementation requires further study.

pregnant women with thyroid peroxidase autoantibodies. JCEM 2007 Apr;92(4):1263-8.

PPT - PD
• The general PD incidence rate of 1,7 % was not higher
in women with hormone abnormalities caused by PPTD.
– Women with a past history of depression present a higher risk of
PD while those who breast fed did not have an increased risk.

Conclusion
• Serum TSH significantly increased and FT4
decreased after COH
• Remaining Q
– TAI status in relation to TSH, FT4 after COH ?
– Only one time point that TSH and FT4 was measured
– Outcome of ART ?
