Neonatal lupus erythematosus is an autoimmune disease in an infant born to a mother with anti-Ro/SSA and with or without anti-La/SSB antibodies. [1] [2] The disease most commonly presents with a diffuse/periorbital rash resembling subacute cutaneous lupus erythematosus and can have systemic abnormalities such as complete heart block or hepatosplenomegaly.

Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
In a suspected antiphospholipid syndrome, lupus anticoagulant is generally tested in conjunction with anti-apolipoprotein antibodies and anti-cardiolipin antibodies, and diagnostic criteria require one clinical event (i.e. thrombosis or pregnancy complication) and two positive blood test results spaced at least three months apart that detect at ...
[19] [20] During pregnancy, anti-Ro antibodies can cross the placenta and cause heart block [21] [22] and neonatal lupus in babies. [23] In Sjögren's syndrome, anti-Ro and anti-La antibodies correlate with early onset, increased disease duration, parotid gland enlargement, disease outside the glands and infiltration of glands by lymphocytes.

anti-Ro/anti-SS-A(for Sjögren's) anti-Scl70 (for Scleroderma) anti-Jo (for Dermatomyositis) Sensitivity and specificity of these tests depends on the type of assay employed, and will therefore vary by lab. The following table illustrates the sensitivity and specificity of ENA antibodies at detecting SLE with the ELISA technique.
In addition, SLE can flare up during pregnancy, and proper treatment can maintain the health of the mother longer. Women pregnant and known to have anti-Ro (SSA) or anti-La antibodies (SSB) often have echocardiograms during the 16th and 30th weeks of pregnancy to monitor the health of the heart and surrounding vasculature.

Antiphospholipid syndrome, or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by antiphospholipid antibodies.APS can lead to blood clots in both arteries and veins, pregnancy-related complications, and other symptoms like low platelets, kidney disease, heart disease, and rash.
