However, IGF-I levels do not always correlate well with the growth response. This study aims to identify the factors affecting the IGF-I concentration and identify the relationship between IGF-I and the treatment response. The data of prepubertal children treated with recombinant human GH for more than one year were obtained from the LG Growth Study (LGS) Database. This study includes patients with idiopathic growth hormone deficiency (IGHD), organic growth hormone deficiency (OGHD), or Turner syndrome (TS) or small for gestational age (SGA). Among 2,021 participants registered in LGS, 366 subjects were selected, 252 had IGHD, 16 had OGHD, 31 had TS, and 67 were SGA. In the IGHD and SGA groups, IGF-I levels had a positive correlation with weight SDS. There was no significant relationship between the pre-treatment IGF-I level and growth response. However, in the IGHD group, the growth response was significantly higher when the change in the IGF-I SDS value was 1 or more (<jats:italic>p<\/jats:italic> = 0.0013). Therefore, IGF-I concentrations should be used as an indicator to monitor the treatment compliance rather than for efficacy determination in Korean children of short stature with GH treatment.<\/jats:p>","DOI":"10.1371\/journal.pone.0252283","type":"journal-article","created":{"date-parts":[[2021,7,19]],"date-time":"2021-07-19T17:26:50Z","timestamp":1626715610000},"page":"e0252283","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":10,"title":["Factors affecting IGF-I level and correlation with growth response during growth hormone treatment in LG Growth Study"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5489-1169","authenticated-orcid":true,"given":"Ji Hyun","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su Jin","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jieun","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Choong Ho","family":"Shin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3471-7803","authenticated-orcid":true,"given":"Ji-Young","family":"Seo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,7,19]]},"reference":[{"key":"pone.0252283.ref001","doi-asserted-by":"crossref","first-page":"230","DOI":"10.1001\/archpedi.156.3.230","article-title":"Effect of growth hormone therapy on height in children with idiopathic short stature: a meta-analysis","volume":"156","author":"BS Finkelstein","year":"2000","journal-title":"Arch Pediatr"},{"key":"pone.0252283.ref002","first-page":"31","article-title":"New paradigms for growth hormone therapy in children","volume":"53","author":"L Wetterau","year":"2000","journal-title":"Horm Res"},{"key":"pone.0252283.ref003","doi-asserted-by":"crossref","first-page":"723","DOI":"10.1016\/S0022-3476(83)80465-X","article-title":"Relationship of somatomedin-C concentrations to pubertal changes","volume":"103","author":"RI Rosenfield","year":"1983","journal-title":"J Pediatr"},{"key":"pone.0252283.ref004","first-page":"1004","article-title":"Serum insulin-like growth factors in normal pregnancy and in pregnancies complicated by preeclampsia","volume":"82","author":"A Hubinette","year":"2003","journal-title":"Acta Obstet Gynecol Scand"},{"key":"pone.0252283.ref005","doi-asserted-by":"crossref","first-page":"1211","DOI":"10.1038\/sj.ejcn.1601948","article-title":"High intakes of skimmed milk, but not meat, increase serum IGF-I and IGFBP-3 in eight-year-old boys","volume":"58","author":"C Hoppe","year":"2004","journal-title":"European J Clin Nutr"},{"key":"pone.0252283.ref006","first-page":"54","volume-title":"Insulin-like growth factors (IGF) and IGF-binding proteins: their use for diagnosis of growth hormone deficiency","author":"WF Blum","year":"2000"},{"key":"pone.0252283.ref007","doi-asserted-by":"crossref","first-page":"1041","DOI":"10.1210\/jcem.87.3.8342","article-title":"Circulating IGF-I levels in childhood are related to both current body composition and early postnatal growth rate","volume":"87","author":"K Ong","year":"2002","journal-title":"J Clin Endocrinol Metab"},{"key":"pone.0252283.ref008","doi-asserted-by":"crossref","first-page":"43","DOI":"10.6065\/apem.2018.23.1.43","article-title":"Design of the long-term observational cohort study with recombinant human growth hormone in Korean children","volume":"23","author":"S Chung","year":"2018","journal-title":"LG Growth Study.
