[Assessment of serum IgG activity correlation against cyclic citrullinated peptide antibodies, topoisomerase I and centromere proteins in Mexican patients with progressive systemic sclerosis].

Objective: To evaluate sera titers for antibodies anti-cyclic citrullinated peptide and their correlation against sera levels of anti-topoisomerase I and anti-centromere antibodies in Mexican patients with systemic sclerosis.

Patients And Methods: Consecutive outpatients with systemic sclerosis who attending to rheumatology clinic at a second level hospital facility. The antibodies anti-cyclic citrullinated peptide, anti-topoisomerase I and anti-centromere were determined by enzymatic immunoassay (ELISA).
