Auto antibody specific for SLE –
Correct Answer: ds DNA

Asterisks indicate high correlation between the antibody the antibody specificity and the disease.* SLE is characterized by bewildering array of autoantibodies, particularly antinuclear antibody.* Best screening test for SLE is demonstration of antinuclear antibody.* ANCA antibody with peripheral rim distribution is seen in - Anti double stranded DNA.* Libman-sach-endocarditis is seen in SLE.* c-ANCA is typical of Wegner's granulomatosis.* p-ANCA is found in most cases of microscopic polyangitis and Chrug-Strauss syndrome.* Perinuclear localization (P-ANCA) where in most of the autoantibodies are specific for myelo-peroxidase (MPO).According to the WHO six patterns of mutually merging renal lesions are seen in lupus nephritis1. Minimal lesion2. Mesengial lupus nephritis3. Focal segmental LN4. Diffuse proliferative LN5. Membranous LN6. Sclerosing LN"Shrinking Lung Syndrome" seen in SLE.
