["Acute liver damage (ALD) is associated with high-dose intravenous (iv) glucocorticoid (GC) (ivGC) pulse therapy in ~1\xa0% of patients for Graves' orbitopathy (GO). It has been proposed that statins may increase the risk of ALD. Here we investigated the frequency of ALD according to the assumption of statins in a large retrospective cohort study.", 'We studied 1076 consecutive patients with GO given ivGC. ALD was defined as an increase in alanine aminotransferase ≥300\xa0U/l.', 'At the time of ivGC, 62 patients were taking statins and 1014 were not. The frequency of ALD has been reported to be 1.2 cases/100,000 statins users and 1300/100,000 in GO patients given ivGC. Thus, the expected frequency of ALD in patients given both statins and ivGC is 1560/100,000. Transferring these data to our series, one would have expected at least 0.96 cases of ALD (~one case), in the 62 patients given both ivGC and statins. However, no cases of ALD were observed in patients given statins, and the previously reported 14 cases of ALD in this series were seen in patients who were not taking statins.'] Are statins a risk factor for liver damage associated with intravenous glucocorticoid pulse therapy for Graves ' orbitopathy?
