However, adverse effects of HCV eradication using direct\u2010acting antiviral agents (DAAs) on renal function have been recently reported. This retrospective study aimed to evaluate renal function with glomerular filtration rate (eGFR) estimated using creatinine (eGFRcre) and cystatin C (eGFRcys). Complete clinical information and preserved serum samples were collected from 207 patients with HCV infection treated with interferon\u2010free DAA at baseline and SVR48 (SVR48). Patients who underwent paired computed tomography (CT) at baseline and \u226512\u00a0months after DAA were evaluated for changes in skeletal muscle mass using the psoas muscle mass index (PMI). eGFRcre significantly worsened at SVR48, while eGFRcys was similar at baseline and SVR48. At baseline, eGFRcre was significantly higher than eGFRcys; eGFRcre and eGFRcys were similar at SVR48. Multivariate analysis revealed that the presence of liver cirrhosis and low\u2010albumin level, as well as cirrhosis and age, was significantly associated with the overestimation of renal function by eGFRcre at baseline and SVR48, respectively. In the 57 patients who underwent paired CT at baseline and\u00a0\u226512\u00a0months after DAA, relative values of PMI significantly increased after DAA. After DAA, in patients with increased PMI (65% 37\/57), eGFRcre significantly worsened but did not change in patients without increased PMI. eGFRcre significantly worsened after DAAs; however, this might not reflect accurate changes in renal function, partially because of changes in skeletal muscle mass. eGFRcys did not change after DAAs, and it is a potential alternative to eGFRcre.<\/jats:p>","DOI":"10.1111\/jvh.13484","type":"journal-article","created":{"date-parts":[[2021,2,17]],"date-time":"2021-02-17T07:51:10Z","timestamp":1613548270000},"page":"755-763","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Changes
