A total of 204 patients with systemic lupus erythematosus (per the American College of Rheumatology classification criteria) were evaluated. Metabolic syndrome was assessed using the American Heart Association(More)
To determine the outcome and identify risk factors for evolution into systemic lupus erythematosus (SLE) in a population of incomplete lupus erythematosus (ILE) patients, we studied the clinical and serologic manifestations in a cohort of 87 ILE patients. ILE patients had at least one but less than four of the American College of Rheumatology (ACR)(More)
