May 18, 2011 (Wednesday) - Neonatal Lupus

A lunchtime presentation: neonatal lupus erythromatosis - a rare condition in 1% of children born to mothers suffering form SLE. It's caused by the trans-placental passage of the IgG antibodies that cause SLE.

Apparently in the case discussed the mother was known to have SLE, but it wasn't considered to be a cause for concern to the baby. My initial reaction was that this is typical of modern medicine - people tend not to think out of their specialities. But then I'm guilty of this - it came as a major revelation that antibodies other than blood group antibodies can cross the placenta....
