Welcome to the forum sel but I am so sorry about what brings you here.
Neonatal lupus is caused by anti ro antibodies crossing the placenta and causing a number of problems either singly or together. It is indeed very rare and they don't know exactly why some babies of anti Ro mums are affected while the vast majority aren't but all the same it is reasonable to take some precautions during pregnancy to check if the most serious problem, heart block, is present so suitable arrangements can be made for the baby's treatment straight after delivery.
The most usual effect is skin problems which should go after a few months when the baby's own immune system takes over and the anti Ro antibodies disappear from the baby's system. Blood abnormalities can occur and usually also disappear as the antibodies leave the baby's body. Another possible problem is with the liver to varying degrees.
Cases of hydrocephalus have been reported due to NLE.
A number of treatments are available depending on the baby's individual needs. There doesn't seem to be any evidence that children born with neonatal lupus are more likely to get an autoimmune disease like lupus or Sjogren's, than other children born to a mother with anti -Ro anti- La or anti- U1 RNP antibodies, or even without these particular antibodies.
It is advisable to keep a quiet eye on NLE babies for any signs of disease especially as they approach puberty and check now and again for possible liver and blood problems. It would also be very prudent to limit sun exposure and use protection which in fact all lupus parents should be doing for their kids
I wonder why they are saying that your son might have chronic lupus. They should certainly be informing you how it is affecting him, and what treatments they propose. If they don't know anything about it they need to get in touch with specialists who do. They sure owe you!
You will find several threads here about neonatal lupus and I expect you will be getting some direct replies. We do have a few members whose babies have been affected.
Please let us know how your son is getting on and ask for any further help.
All the best
Bye for now
Clare
