Abstract

Summary: Objective We investigated whether inhibition of oestrogen biosynthesis with the aromatase inhibitor, letrozole, during adolescence improves near‐final height in boys with constitutional delay of puberty. Patients and methods Seventeen boys with constitutional delay of puberty were randomized to receive testosterone (T) enanthate (1 mg/kg i.m.) every 4 weeks for 6 months in combination with placebo (Pl, n = 8), or the aromatase inhibitor letrozole (Lz, 2·5 mg/day orally) ( n = 9), for 12 months. After treatment, patients were followed up until near‐final height. Height discrepancy was calculated as near‐final height minus mid‐parental target height. Measurements The primary end point was the difference in near‐final height between the groups treated either with T + Pl or T + Lz. Secondarily, height discrepancy and gain in height standard deviation score (SDS) were analysed in both groups. Results Boys treated with T + Lz reached a higher mean near‐final height than did boys on T + Pl (175·8 vs. 169·1 cm, respectively, P = 0·04). In T + Lz‐treated boys, mean near‐final height did not differ from their mid‐parental target height (175·8 vs. 177·1 cm, P = 0·38), whereas in T + Pl‐treated boys, mean near‐final height was lower than mid‐parental target height (169·1 vs. 173·9 cm, P = 0·007). T + Lz‐treated boys had a greater increment in height SDS over the pretreatment height SDS than T + Pl‐treated boys (+1·4 SDS vs. +0·8 SDS, P = 0·03). Conclusions Our findings indicate that in adolescent boys an increase in adult height can be attained by use of aromatase inhibitors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
