There was an error in table 1 of the article by Micheloud D, Calderón M, Caparros M, D’Cruz D P. Intravenous immunoglobulin therapy in severe lupus myocarditis: good outcome in three patients. Ann Rheum Dis 2007;66:986–7. The units IU/ml and ug/l should refer to CK and troponin levels, respectively. There should also be an extra line in the table. The corrected table is available on our website at http://ard.bmj.com/Supplemental.
