Primary management of TS during childhood and adolescence comprises treatment with human growth hormone (hGH) and, in cases with early loss of ovarian function, hormone replacement therapy (HRT). Given that metabolic parameters are altered when HRT is applied during menopause, we analyzed whether metabolic changes might be positively or negatively affected within 10 years after HRT and\/or hGH in girls with TS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>Observational study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data were collected from the medical records of 31 girls with TS attending two endocrinologic centers in Germany between 2000 and 2020.

Treatment with hGH was given to 96.8% of the girls, starting at an average age of 99.06 \u00b1 8.70 months, and was continued for 67.53 \u00b1 6.28 months. HRT was administered to 80.6% of all patients and was started at a mean age of 164.4 \u00b1 4.54 months. During the follow-up, we did not observe any significant absolute changes in lipid parameters, but we detected beneficial effects of childhood hGH: significantly lower cholesterol (-0.206\/month; p = 0.006), lower low density lipoprotein cholesterol (-0.216\/month; p = 0.004), and higher high density lipoprotein cholesterol (+0.095\/month; p = 0.048). Insulin concentrations, showed a significant increase attributable to hGH treatment (+0.206\/month; p = 0.003), which was ameliorated by concomitant or subsequent HRT (-0.143\/month; p = 0.039).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Treatment with hGH and HRT is provided to most girls with TS. Metabolic effects are associated with both modalities. Monitoring of metabolic changes appears to be important to detect unfavorable effects, and could guide treatment adjustment and duration.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2020.586055","type":"journal-article","created":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T05:57:00Z","timestamp":1607925420000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Increased Insulin Concentrations During Growth Hormone Treatment in Girls With Turner Syndrome Are Ameliorated by Hormone Replacement Therapy"],"prefix":"10.3389","volume":"11","author":[{"given":"Sabine Elisabeth","family":"Segerer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan Georg","family":"Segerer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl-Joachim","family":"Partsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfgang","family":"Becker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Nawroth","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2020,12,14]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1530\/EJE-13-0900","article-title":"Transitions in endocrinology: treatment of Turner\u2019s syndrome during transition","volume":"170","author":"Gawlik","year":"2014","journal-title":"Eur J Endocrinol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/det089","article-title":"Anti-Mullerian hormone levels in girls and adolescents with Turner syndrome are related to karyotype, pubertal development and growth hormone treatment","volume":"28","author":"Visser","year":"2013","journal-title":"Hum Reprod"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1159\/000485321","article-title":"Pubertal development profile in patients with Turner syndrome","volume":"27","author":"Negreiros","year":"2014","journal-title":"J Pediatr Endocrinol Metab"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1210\/jcem.82.6.3970","article-title":"Spontaneous pubertal development in Turner\u2019s syndrome.
