The Research Registry for Neonatal Lupus

Study Overview
=================
Brief Summary
-----------------
Women with lupus and other related disorders produce certain antibodies in the blood. Some women have these antibodies even if they have not yet developed symptoms of lupus or Sjogren's syndrome. When these women become pregnant, they may pass the antibodies to their infants. The infants may then develop a disease called neonatal lupus. The symptoms of neonatal lupus include an abnormally slow heart beat (heart block) and a skin rash. This registry collects information on women and infants affected by neonatal lupus as well as other family members who may be healthy.

Detailed Description
-----------------
Neonatal lupus is a disease seen in babies born to mothers who have antibodies to SSA/Ro and/or SSB/La proteins. The mother may have systemic lupus erythematosus, Sjogren's syndrome, or be otherwise healthy. Heart block and a characteristic skin rash are the primary manifestations of neonatal lupus. The Research Registry for Neonatal Lupus was initiated in 1994 to help basic scientists and clinicians better understand the cause of neonatal lupus and discover a cure. The Research Registry is a central repository of patient information, sera, and DNA. The Registry provides blood samples (kept anonymous) to scientists studying neonatal lupus. Information from the registry forms the basis of family counseling and tracks important data such as recurrence rates in subsequent pregnancies and the effects of treatments. The Research Registry also serves as an educational resource for women who are eager to learn about this disease. Women with a child affected by neonatal lupus may enroll in the Registry. Women can be self referred or referred by their doctors. Siblings of women with a child affected by neonatal lupus, fathers and maternal grandparents of children with neonatal lupus, and unaffected siblings of a child with neonatal lupus are also invited to participate in this study. All information on the mother and her family is confidential; only nonidentifying information will be provided to researchers. Women interested in the registry will be sent articles and educational materials about neonatal lupus, a consent form for the Registry, and an enrollment questionnaire. Participants will be asked to sign a medical records release form. Participants will also be asked to donate a blood sample for antibody testing and DNA isolation.
