Aromatase inhibitors block androgen conversion to estrogen and have been used off-label in children with short stature to improve adult height. There are no adequately powered studies examining the use of aromatase inhibitors in children with CAH with advanced bone age and reduced predicted adult height.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Records of CAH patients treated with anastrozole were reviewed. Z-scores of bone age, predicted adult height, and height corrected for bone age were examined over an 8-year period. Outcome changes were analyzed using weighted mixed-effects models, adjusting for sex, diagnosis, age at diagnosis, and average hydrocortisone dose before and during treatment with anastrozole.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In 60 patients (26 females; 52 classic, 8 nonclassic) started on anastrozole therapy, the mean bone age Z-score decreased from 4.2 to 2.0 at 4 years and 1.3 at 6 years (both P &amp;lt; .001); predicted adult height Z-score improved from \u22122.1 to \u22120.45 at 4 years and 0.18 at 6 years (both P &amp;lt; .001); corrected height Z-scores improved from \u22121.7 to \u22120.33 at 4 years and 0.18 at 6 years (P &amp;lt; .001).
