In these patients recruited during hospitalization, the presence of dyslipidemia was less frequent than in our study (18% hypercholesterolemia and 16% elevation of LDL).23 Also compared to the findings of this study, in other outpatient studies10,17 anemia was more frequent (38.6%), as were hydroelectrolytic changes (hyponatremia in 19.7% and hypokalemia in 19.7%), but with similar ALT elevation values (12.2%). This evidence concerns the gene GPT and anemia.
