TB in a pregnant woman

    Does anyone know... If a pregnant woman becomes infected with TB, can the TB cross the placenta? And if so, what damage can it do to the fetus?

    I just finished my OB rotation and a patient had TB. They started treatment (INH) and I believe the meds do cross the placenta but are of no harm to the developing fetus. The baby may be born with TB but I believe it's rare.

    As for TB crossing the placenta.........I am 'assuming' yes-because babies can be born with congenital TB?

    I googled "tb + pregnancy" and got these results:

    This would apply to a mom w/active TB, NOT just a + skin test.

    Pulmonary TB does not cross the placenta; extra-pulmonary TB (untreated) might cause problems. (I have seen TB cultured from a placenta.) The baby can become infected w/TB via inhalation of infectious droplet nuclei from mom and frequent face-to-face interaction w/her when being fed and cared for. TB infection in babies and small children can have devastating results--rarely seen in this country, but ?don't know current situation in 3rd world countries.

    If you're interested, go to the World Health Organization website, and search TB.
