Purpose: To describe the data from the Greek cohort of the Genetics and Neuroendocrinology of Short Stature International Study (GeNeSIS).

Methods: GeNeSIS was a prospective, open-label, multinational, observational study collecting information on clinical outcomes and treatment safety of children with growth disorders treated with growth hormone (GH), according to national indications. After informed consent, 305 patients (143 females), including 255 patients with growth hormone deficiency (GHD) and 30 with Turner syndrome (TS), from eight investigational sites, were enrolled in Greece. Demographic data, treatment efficacy, and adverse events were reported at the discretion of attending physicians.

Results: Treatment with GH was undertaken for 247/255 patients with GHD and 29/30 with TS. The majority of patients treated with GHD (73.7%) and TS (84%) with recorded Tanner stage were prepubertal at enrolment. Among patients treated with GHD and TS, 70.45% and 55% were GH-naïve at study entry, respectively. Height standard deviation score (SDS), height velocity SDS, and height SDS-target height SDS numerically improved during the 4-year observation period. The effect of GH treatment was more prominent in the first year of treatment, especially in the GHD group.

Conclusions: In the Greek cohort of GeNeSIS, GHD is the most frequent indication for GH treatment, followed by TS. While the latter is diagnosed somewhat earlier, GH treatment is not as efficacious as for patients with GHD. No major safety issues were reported during follow-up. The results, which are in accordance with the international literature, should be interpreted in the context of observational studies.
