We read the article by Worthmann et al1 with interest. The authors investigated whether the combination of recombinant tissue-type plasminogen activator (rtPA) and erythropoietin (EPO) increases the release of endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine (ADMA). The patients were divided into 4 groups according to treatment: placebo, EPO, rtPA+placebo, and EPO+rtPA. They found that ADMA levels increased during the observation time in the EPO, the EPO+rtPA, and the placebo groups, whereas a treatment effect on ADMA levels was revealed only in the rtPA+placebo group when adjusted for age and infection at …
