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 ...
Pregnancy outcomes in women with lupus who receive kidney transplants are similar to those of transplant recipients without lupus. [2] 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.

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. [3]
Anti-Ro antibodies are also found less frequently in other disorders including autoimmune liver diseases, coeliac disease, autoimmune rheumatic diseases, cardiac neonatal lupus erythematosus and polymyositis. [19] [20] During pregnancy, anti-Ro antibodies can cross the placenta and cause heart block [21] [22] and neonatal lupus in babies. [23]
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 ...
Although the autoimmune CHB has a relatively high mortality and morbidity rates, the chance of kids from -mothers positive to anti-Ro\SSA and/or anti-La\SSB antibodies- to suffer from CHB is only around 1-5%, [9] [7] [10] which suggests the existence of other factors to influence the disease such as genetic and environmental factors.
Affected pregnant women follow careful clinical observation because they are more likely to see disease progression. Those with the disease at the beginning of pregnancy will keep the disease undifferentiated against 25% who progress to a defined disease at the end of pregnancy. In addition, 45% of pregnancies with the disease end in preterm birth.
In immunology, passive immunity is the transfer of active humoral immunity of ready-made antibodies.Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune ...
