Antibodies to histones3. Antibodies to non histone proteins bound to DNA4. Antibodies against nuc leolar antigensMost commonly used method to diagnose antinuclear antibodies - Indirect immunofluorescenceThey are associated with SLE as well as other autoimmune diseases basic patterns of ANA# Homogenous or diffuse nuclear staining - antibodies to histone chromatin# Rim or peripheral staining - antibodies to DS DNA# Speckled pattern - eg: Sm antigen, SS-A, SS-B# Nucleolar pattern - systemic sclerosis# Best screening test for sle - ANA# Most specific in sle - anti ds DNA# Autoantibody in sle with decreased risk of nephritis - anti ro, anti la# Autoantibody in drug induced sle - antihistone antibody ( aiims nov 2007)# Autoantibody associated with depression or psychosis in SLE - anti ribosomal p# Autoantibody associated with subcutaneous and neonatal lupus - anti ro antibody# Autoantibody in SLE correlating with active CNS lupus - antineuronal antibodyAntinuclear antibodies in various autoimmune diseases# Primary biliary cirrhosis- antimitochondrial antibody# Inflammatory myopathy- antihistidyl t-RNA synthetase (anti Jol)# Sjogrens syndrome- anti Ro and anti La# Diffuse scleroderma- anti topoisomerase antibody# CREST syndrome- anti centromere antibody # Celiac disease- antiendomysial antibody# Crohn disease- anti saccharomyces cervisea antibody# Ulcerative colitis- ANCA # Rheumatoid arthritis- anti ccp antibody
