RT Journal Article T1 Isolated Growth Hormone Deficiency and Idiopathic Short Stature: Comparative Efficiency after Growth Hormone Treatment up to Adult Height. A1 Ariza-Jimenez, Ana-Belen A1 Leiva Gea, Isabel A1 Martinez-Aedo Ollero, Maria Jose A1 Lopez-Siguero, Juan Pedro K1 final height K1 growth hormone deficiency K1 growth hormone treatment K1 idiopathic short stature AB Treatment with growth hormone (GH) is not approved for idiopathic short stature (ISS) in Europe. To compare the growth of children treated with isolated GH deficiency (IGHD) vs. ISS-treated and untreated children. A retrospective descriptive study of patients treated in the last 14 years for IGHD (Group A), in comparison with ISS-treated (Group B) and untreated (Group C) subjects. Group A had 67 males, who showed a height gain of 1.24 SD. Group B had 30 boys, who showed a height gain of 1.47 SD. Group C had 42 boys, who showed an improvement of 0.37 SD. The final heights were -1.52 SD, -1.31 SD, and -2.03 SD, respectively. Group A and C did not reach their target heights (with differences of 0.27 SD and 0.59 SD, respectively). Group B surpassed their target height by 0.29 SD. The final heights of the IGHD and treated ISS are similar. Treated groups were taller than untreated groups.
