Therapy with\n l<\/jats:sc>\n -thyroxine was re-instituted when TSH rose >10\u2009U\/L and\/or fT4 was below the normal range. The patients were followed up when TSH concentrations were between 5 and 10\u2009U\/L and fT4 was in the normal range.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n At baseline, TSH was in the normal range in 139 patients, and was between 5 and 10\u2009U\/L in 9 patients. Treatment was re-instituted after 2 months in 37 (25.5%) patients, after 6 months in 13 patients (6.99%), after 12 months in 12 patients (8.6%), and after 24 months in an additional 3 patients (3.1%). At 24 months, 34 patients (34.3%) still required no treatment. TSH concentration >10\u2009U\/L at the time of diagnosis was the only predictive factor for the deterioration of thyroid function after\n l<\/jats:sc>\n -thyroxine discontinuation.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n This study confirms that not all children with HT need life-long therapy with\n l<\/jats:sc>\n -thyroxine, and the discontinuation of treatment in patients with a TSH level <10\u2009U\/L at the time of diagnosis should be considered.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1530\/ec-17-0023","type":"journal-article","created":{"date-parts":[[2017,3,27]],"date-time":"2017-03-27T20:10:17Z","timestamp":1490645417000},"page":"206-212","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-10","source":"Crossref","is-referenced-by-count":18,"title":["Thyroid function in children and adolescents with Hashimoto's thyroiditis after l-thyroxine discontinuation"],"prefix":"10.1530","volume":"6","author":[{"given":"Giorgio","family":"Radetti","sequence":"first","affiliation":[{"name":"1PediatricsRegional Hospital, Bolzano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariacarolina","family":"Salerno","sequence":"additional","affiliation":[{"name":"2PediatricsUniversity Federico II, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Guzzetti","sequence":"additional","affiliation":[{"name":"3Pediatric EndocrinologyOspedale Pedatrico Microcitemico \u2018A.
