Background and Objective: The American Norditropin Studies: Web-Enabled Research (ANSWER) Program is a long-term, US-based, non-interventional study designed to collect information on the effectiveness and safety of Norditropin® growth hormone (GH). From June 2002 to September 2016, 20,204 pediatric patients were enrolled by their treating physicians, including 1,003 patients with Turner syndrome (TS). This analysis compares cumulative GH doses when adjusting G...

Background: Klinefelter syndrome (KS) is a male genetic disorder defined by the karyo type 47,XXY. Adult males with KS are at increased risk for osteoporosis, based on androgen deficiency. Androgen replacement is standard in adolescent and adults with KS, but has not been used earlier in childhood. We performed a clinical trial to study the effects of childhood, low-dose androgen replacement on bone density in boys with KS.Objective and hypotheses: To me...

Background: The assessment of bone age increments is important when monitoring treatment in many conditions in pediatric endocrinology. However, manual rating suffers from significant rater variability. Automated bone age assessment could provide increased precision, and also assess increments of bone health index (BHI) from the same X-rays.Objective and hypotheses: To assess the precision of automated assessment of increments of bone age and BHI.<p ...

Objectives: Limited information is available on how very young children with growth hormone deficiency (GHD) respond to growth hormone (GH) replacement. We compared response to 1 year of GH therapy in children aged <2 years and prepubertal children aged ≥2 years.Methods: The two non-interventional, multicentre studies, NordiNet® International Outcome Study (IOS) (NCT00960128) and the ANSWER Prog...

Background: Late initiation of GH results in suboptimal adult height for many women with TS. In a landmark, randomized, controlled, clinical trial (“Toddler Turner” study) we showed that 2 y of early GH (ET group) started at 1.98±1.01 y, resulted in height SDS difference of 1.6±0.6 SDS vs. early untreated group (EUT).Objective and hypotheses: It was unclear if early height gains would result in taller adult heights, so patients were f...

Background: To date, one randomized, controlled, clinical trial (RCCT) demonstrated that GH-treated patients with SHOX deficiency (SHOX-D) had GH-mediated height gain comparable to that of girls with Turner syndrome (TS). No new safety concerns were identified, but the study was limited by small sample size.Objective and hypotheses: To examine long-term outcomes in patients treated in standard clinical practice, we assessed final height (FH) and safety o...

Introduction: Noonan syndrome (NS) and Turner syndrome (TS) are distinct genetic disorders with similarities in phenotype, including short stature. The NordiNet® IOS and the ANSWER Program® are observational studies evaluating effectiveness and safety of GH treatment in real-world practice.Methods: The study population included children with NS or TS with puberty recordings, enrolled in NordiNet® IOS or ANS...

Background: GH treatment in children born small for gestational age (SGA) has both short- and long-term growth-promoting effects and is approved in Europe and the USA (recommended dosages 0.25–0.47 mg/kg per week).Objective and hypotheses: To assess final height (FH) and safety outcomes in SGA patients receiving GH treatment in routine clinical practice using data from GeNeSIS.Method: 1208 GH-treated SGA patients were enrolled...

Background: GH treatment for ISS received first approval in the USA in 2003 based on data from two controlled clinical trials. Eligibility is restricted to those with baseline (BL) height standard deviation score (HtSDS) ≤−2.25; other approvals followed, but not in Europe.Objective and hypotheses: To assess outcomes of GH therapy in a large cohort of patients (pts) treated in routine clinical practice.Methods: Short-ter...
