However, clinical implications of telomere length in biopsy-proven non-alcoholic fatty liver disease (NAFLD) patients remain unclear. Therefore, this study aimed to investigate the association of telomere length with the histological severity of NAFLD. The cross-sectional data derived from the prospectively enrolled Boramae NAFLD registry (n\u2009=\u200991) were analyzed. The liver tissues and clinical information were obtained from both NAFLD patients and non-NAFLD subjects. Binary logistic regression was performed to identify the independent association between telomere length and the histological severity of NAFLD. A total of 83 subjects with or without biopsy-proven NAFLD were included for analysis: non-NAFLD in 23 (27.7%), non-alcoholic fatty liver in 15 (18.1%), and non-alcoholic steatohepatitis (NASH) in 45 (54.2%). Telomere length measured from liver tissues showed a strong negative correlation (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) with age, regardless of NAFLD status. Therefore, telomere length was corrected for age. Age-adjusted telomere length than decreased gradually with an increasing severity of fibrosis in patients with NAFLD (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.028). In multivariate analysis, age-adjusted telomere length (odds ratio [OR] 0.59; 95% CI 0.37\u20130.92; <jats:italic>p<\/jats:italic>\u2009=\u20090.019) and high-density lipoprotein cholesterol (OR 0.94; 95% CI 0.80\u20130.99; <jats:italic>p<\/jats:italic>\u2009=\u20090.039) were independently associated with significant fibrosis. The age-adjusted telomere length tends to decrease along with the fibrosis stage of NAFLD. In particular, among the histological components of NAFLD, fibrosis severity seems to be related to telomere length in the liver.<\/jats:p>","DOI":"10.1038\/s41598-021-97385-2","type":"journal-article","created":{"date-parts":[[2021,9,9]],"date-time":"2021-09-09T10:06:24Z","timestamp":1631181984000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Association between telomere length and hepatic fibrosis in non-alcoholic fatty liver disease"],"prefix":"10.1038","volume":"11","author":[{"given":"Hee Kyung","family":"Shin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong Hwan","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung Hwan","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young-Joo","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young Ju","family":"Suh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin-Woo","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Won","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"The Korean Nonalcoholic Fatty Liver Study Group (KNSG)","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,9,9]]},"reference":[{"key":"97385_CR1","doi-asserted-by":"publisher","first-page":"2388","DOI":"10.1101\/gad.13.18.2388","volume":"13","author":"X Zhang","year":"1999","unstructured":"Zhang, X., Mar, V., Zhou, W., Harrington, L. & Robinson, M.
