Context
KIGS is a large, international database (1987-2012) of children treated with recombinant human growth hormone (rhGH) in real-world settings.
Objective
To evaluate the safety and efficacy of rhGH from the full KIGS cohort
Design, Patients, Setting, and Intervention
Data were collected by investigators from children with growth disorders treated with rhGH (Genotropin® [somatropin]; Pfizer, NY). Safety was evaluated in all treated patients, and efficacy in those treated for ≥1 year. A subgroup included patients treated for ≥5 years (≥2 years prepubertal) who had reached near-adult height (NAH).
Main Outcomes
Adverse events (AEs), serious AEs (SAEs), and height growth.
Results
The full KIGS cohort (N = 83,803 [58% male]) was treated for idiopathic GH deficiency (IGHD; 46.9%), organic GHD (10.0%), small for gestational age (SGA; 9.5%), Turner syndrome (TS; 9.2%), idiopathic short stature (ISS; 8.2%), and others (16.2%). Median rhGH treatment duration was 2.7 years and observation 3.1 years. SAEs occurred in 3.7% of patients and death in 0.4%. The most common SAEs were recurrence of craniopharyngioma (n = 151), neoplasm (n = 99), and cancer (n = 91); and scoliosis (n = 91). Median first-year delta height-SDS (Prader) in prepubertal patients was 0.66 (IGHD), 0.55 (ISS), 0.58 (TS), 0.71 (SGA). Median gains in NAH-SDS were 1.79 (IGHD), 1.37 (ISS), and 1.34 (SGA) for boys, and 2.07 (IGHD), 1.62 (ISS), 1.07 (TS), and 1.57 (SGA) for girls.
Conclusion
Data from KIGS, the largest and longest running international database of rhGH-treated children, show that rhGH is safe and increases short-term height gain and adult height across GHD and non-GHD conditions.
