Background/Purpose: Congenital heart block (CHB) occurs in 1 to 2 % of pregnancies exposed to anti-SSA antibodies. Few data are available regarding the risk of the mothers of fetuses/children with CHB to develop an autoimmune disease.
Methods: The inclusion criteria in the French registry of neonatal lupus are the positivity of anti-SSA and/or anti-SSB antibodies and a manifestation of neonatal lupus. In this retrospective study, we analyzed the data of the mothers who had a foetus/child with CHB.
Results: 184 mothers of 205 fetuses/children with CHB were included: 99.5% (183) had anti-SSA antibodies and 69.6% (128) had anti-SSB antibodies.
At the time of their first diagnosis of CHB, 136 mothers (73.9%) were asymptomatic. The 48 mothers (26.1%) with an auto-immune disease had a systemic lupus erythematosus (SLE, n=20, associated with antiphospholipid syndrome with venous thrombosis in 2 cases), a sjogren syndrome (n=12), an undifferentiated connective tissue disease (UCTD, n=10), a rheumatoid arthritis (n=3), a idiopathic thrombocytopenic purpura (n=1), an autoimmune hepatitis (n=1) and a systemic scleroderma (n=1). Clinical manifestations of SLE mainly included cutaneous and articular manifestations and only 8 mothers had more severe manifestations (renal, neurological, pericarditis, hematological). Only one had received cyclophosphamide.
After a median follow up period of 8.8 years [1 day-36.5 years], 75 mothers (40.8%) remained asymptomatic. The 109 mothers (59.2%) with an autoimmune disease had a Sjogren syndrome (n=42), an SLE (n=37, including 2 associated with an antiphospholipid syndrome), an UCTD (n=20), a rheumatoid arthritis (n=3), an SLE associated with a Sjogren syndrome (n=2), a idiopathic thrombocytopenic purpura (n=2), an autoimmune hepatitis (n=1), a systemic scleroderma (n=1) and a primary obstetrical antiphospholipid syndrome (n=1).
Conclusion: At the time of the CHB diagnosis in their offspring, a third of the mothers had a diagnosis of autoimmune disease. During the follow up period, another third developed an autoimmune disease. The remaining third was still asymptomatic after a median follow up period of 8.8 years [1 day-36.5 years].
