ESR, erythrocyte sedimentation rate; CRP, C reactive protein; ANA, antinuclear antibodies; p-ANCA, perinuclear antineutrophil cytoplasmic antibodies; c-ANCA, antineutrophil cytoplasmic antibodies; anti-MPO, anti myeloperoxidase antibodies; RF, rheumatoid factor; anti CCP, anti cyclic citrullinated peptide antibodies; Sm-RNP, Smith-ribonucleoprotein antibodies; CK, creatine kinase; ds-DNA, double stranded DNA; LAC, lupus anticoagulant. *ANA was obtained by indirect immunofluorescence. **dsDNA was obtained by multiplexed assay on BioPlex 2200 (BioRad)
