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 ...
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.

Those with anti-Jo1 antibodies had less remission of myositis and more relapses than those with anti-PL-12 and anti-PL-7 antibodies. [64] Anti-Jo-1 and anti-Ro52 antibodies co-occurring were linked to an increased risk of neoplasm , a symptomatic severe variant of interstitial lung disease, myositis, and arthritis exacerbation.
The bacteria releases a toxin that causes a bright red blotchy rash that has a sandpaper-like texture, and the rash can spread to the entire body and usually first appears on the groin, neck, and ...
The Sharp criteria require at least four major criteria, as well as anti-U1-RNP antibody titer of at least 1:4000, or two major criteria from criteria 1, 2, and 3, and two minor criteria, plus anti-U1-RNP antibody titer of at least 1:1000. The sharp criteria also excludes anyone with a positive anti-Sm antibody. [69]
Bullous pemphigoid (a type of pemphigoid) is an autoimmune pruritic skin disease that typically occurs in people aged over 60, that may involve the formation of blisters in the space between the epidermal and dermal skin layers.
Around 80% of people with DM test positive for ANA and around 30% of people have myositis-specific autoantibodies which include antibodies to aminoacyl-tRNA synthetases (anti-synthetase antibodies), including antibodies against histidine—tRNA ligase ; antibodies to signal recognition particle (SRP); and anti-Mi-2 antibodies.

A photomicrograph of Candida albicans showing hyphal outgrowth and other morphological characteristics.. Mannan (oligomannan) is a component of the yeast cell wall.Antibodies to yeast mannans are found at increased frequency in Crohn's disease and ASCA positive Crohn's tend to have lower low levels of mannan-binding lectin.
