Resumen
Background: Certain associated and specific myositis antibodies are related to certain clinical phenotypes of dermatomyositis (DM), disease severity and the presence of cancer. Aim: To describe the clinical profile of Chilean patients with DM and their associated and specific myositis antibodies. Material and Methods: Review of medical records of 15 patients with DM aged 31 to 72 years. Their clinical characteristics, laboratory tests and complementary tests were reviewed. In serum samples from each patient the presence of 16 specific antibodies was analyzed by immunoblot technique (Myositis Profile Euroline Blot test kit). Results: Fourteen (93.3%) patients had skin manifestations, five (33.3%) had pulmonary involvement, two (13.3%) had an associated cancer and nine (60%) had specific antibodies associated with myositis. Conclusions: These patients with DM had a clinical profile similar to what has been described elsewhere. The profile of myositis specific antibodies was different from reports in other populations.
