Aims: This study aimed to evaluate final adult height (AH) after recombinant human growth hormone (GH) treatment of girls with Turner syndrome (TS) and to elucidate the predicting factors for their growth response. Methods: We enrolled 73 patients with TS who underwent GH treatment and reached AH and 14 patients who did not undergo treatment. To assess the effectiveness of GH therapy, we evaluated final AH, height gain over the predicted AH, and height gain over the projected AH. In addition, to analyze the factors affecting final AH, we studied correlations between final AH (or height SDS, height gain) and treatment variables. Results: GH therapy was started at a mean age of 8.87 ± 3.73 years, and the treatment duration was 6.47 ± 3.02 years. The patients in the treated group reached a final AH of 152.03 ± 4.66 cm (final AH SDS for the general population: –1.93 ± 1.03) with a gain over projected AH at the start of treatment of 12.21 ± 4.33 cm. The untreated control subjects had a final AH of 143.57 ± 4.06 cm with a gain over projected AH at the first visit of 3.89 ± 3.80 cm. Final AH and AH SDS were positively correlated to height SDS at the start of treatment. Thirty-five patients out of the 73 GH-treated patients (47.9%) attained to a normal range of height for Korean girls. The patients having attained to a normal height range after GH treatment had shown a higher height SDS at the start of GH treatment, a higher mid-parental height SDS, and a younger age at initiation of estrogen. Conclusions: Our findings demonstrate that GH treatment at an early age is effective in improving the final height SDS and height SDS gain in TS patients. Therefore, GH administration at an early age is important for final height gain.

OBJECTIVES: We aimed to evaluate the factors influencing true adult height (HT) after long-term (from 1987 to 2000) GH treatment in Ullrich-Turner syndrome (UTS) based on modalities conceived in the 1980s. DESIGN: Out of 347 near-adult (>16 Years) patients from 96 German centres, whose longitudinal growth was documented within KIGS (Pharmacia International Growth Database), 188 (45, X=59%; bone age >15 Years) were available for further anthropometric measurements. RESULTS: At a median GH dose of 0.88 (10th/90th percentiles: 0.47/1.06) IU/kg per week, a gain of 6.0 (-1.3/+13) cm above the projected adult height was recorded. Variables were recorded at GH start, after 1 Year GH, puberty onset, and last visit on GH therapy. At these visits, the median ages were 11.7, 12.7, 14.2, 16.6 and 18.7 Years; and median heights, 0.4, 1.1, 1.7, 1.7 and 1.3 SDS (UTS) respectively. Height gain (DeltaHT) after GH discontinuation was 1.5 cm. Total DeltaHT correlated (P<0.001) negatively with bone age and HT SDS at GH start, but positively with DeltaHT after the first Year, DeltaHT at puberty onset, and GH duration. Final HT correlated (P<0.001) positively with HT at GH start, first-Year DeltaHT, and HT at puberty onset. Body mass index increased slightly (P<0.05), with values at start and adult follow-up correlating highly (R=0.70, P<0.001). No major side effects of GH occurred. CONCLUSIONS: GH dosages conceived in the 1980s are safe but too low for most UTS patients. HT gain and height are determined by age and HT at GH start. Height gain during the first Year on GH is indicative of overall height gain. After spontaneous or induced puberty, little gain in height occurs.

<b><i>Context:</i></b> Treatment with growth hormone (GH) is considered effective in improving adult height (AH) in Turner syndrome (TS). However, there are few studies comparing AH between treated patients and a concurrent untreated group. <b><i>Objective:</i></b> To assess the efficacy of GH treatment in improving AH in TS and to review previous published studies with treated and untreated groups. <b><i>Participants and Methods:</i></b> We retrospectively analyzed clinical data and AH of a large cohort of GH-treated (<i>n</i> = 168) and untreated (<i>n</i> = 131) patients with TS. Data are shown as median and interquartile range (IQR). We assessed pretreatment variables related with AH and compared our results with 16 studies that also included an untreated group. <b><i>Results:</i></b> The GH-treated group was 6.2 cm taller than the untreated group (AH = 149 cm [IQR 144.5–152.5 cm] vs. 142.8 cm [IQR 139–148 cm], <i>p</i> &#x3c; 0.001) after 4.9 years of GH treatment with a dose of 0.35 mg/kg/week. AH SDS corrected for target height (TH) was 7.2 cm higher in GH-treated patients. AH SDS ≥−2 was more frequent in GH-treated patients (43%) than in untreated patients (16%, <i>p</i> &#x3c; 0.001). AH SDS was also more frequently within the TH range in the GH-treated group (52%) than in the untreated group (15%, <i>p</i> &#x3c; 0.001). Height SDS at start of GH therapy and TH SDS were positively correlated with AH (<i>p</i> &#x3c; 0.001; <i>R</i><sup>2</sup> = 0.375). Considering the current result together with previous similar publications, a mean AH gain of 5.7 cm was observed in GH-treated (<i>n</i> = 696) versus untreated (<i>n</i> = 633) patients. <b><i>Conclusions:</i></b> Our study strengthens the evidence for efficacy of GH therapy in patients with TS from different populations.

Method Of Evaluation

GH therapy has been applied to patients with Turner syndrome for over a decade, but small sample size, delayed initiation of therapy into adolescent age and comparison with historical control subjects limit the usefulness of these studies for appraisal of the effect of GH on final adult height. We report 49 young women with Turner syndrome who completed a clinical trial in an open, non-randomized, age-matched controlled study of GH, given as daily s.c. injections at a weekly dose of 8.2 mg/m(2) for 1.9-7.5 years. Final height was defined as the measurement taken 2 years or more after height velocity declined below 2 cm/year and after a bone age of 15 'years'. The gain in height was evaluated in three ways. The mean final height gain, compared with the control group, was 4.4 cm. When corrected for the projected height at inception of therapy, the mean gained height was 5.3 cm above the control group. Shorter girls showed better response to GH then did taller girls. After correcting for parental height, the mean gain was 4.7 cm. The adult height of the GH-treated Turner women was significantly correlated with the target height, whereas no such correlation was obtained for control untreated women. Furthermore, no correlation was observed between height gain and the age or duration of GH therapy, or the age of inception of estrogen replacement therapy. It is concluded that GH therapy augments final height of girls with Turner syndrome by a mean 4.4-5.3 cm, depending on the method of evaluation, and that shorter girls may be preferred candidates for such therapy. GH therapy can be initiated after age 10 years and there is no reason to delay estrogen therapy beyond the age of 12. Indirect evidence suggests that high-dose GH therapy may surmount a pathophysiological resistance in the GH-IGF-I axis.

The Impact

Objective. We aim to investigate the long-term benefits of growth hormone (GH) therapy in short stature adolescents and adults with pituitary stalk interruption syndrome (PSIS), which would be beneficial for future clinical applications.Design and Methods. In this study, initial height, final height, total height gain, and GH treatment history were retrospectively investigated in 75 Chinese PSIS patients. We compared height gain between the GH treated cohort and untreated cohort and explored the impact of different GH therapy duration on height gain.Results. For GH treated patients, their final height (SDS) increased from-1.99±1.91(−6.93~2.80) at bone age (BA) of 11.2 (5.0~17.0) years to-1.47±1.64(−7.82~1.05) at BA of 16.6 (8.0~18.0) years (P=0.016). And GH treated patients had more height gain than the untreated patients (P<0.05). There was a significant difference between the different GH therapy duration groups (P=0.001): GH 0 versus GH 3,P=0.000; GH 1 versus GH 3,P=0.028; GH 2 versus GH 3,P=0.044.Conclusion. Adult Chinese PSIS patients with short stature benefited the most from at least 12 months of GH therapy. Although patient diagnosis age was lagged behind in the developing countries, GH treatment was still effective for them and resulted in a higher final height and more height gain.

Abstract Background: Short stature is the most frequent clinical manifestation in Turner syndrome (TS), occurring in 98% of these patients. Growth hormone was shown to improve adult height in TS patients from diverse genetic backgrounds. However, there are few studies on adult height in TS patients from developing countries, where the diagnosis is frequently delayed. Objective: To compare adult height between GH-treated and untreated TS patients. Patients and methods: 120 GH-treated and 109 GH-untreated TS patients from 3 referral hospitals in Brazil were evaluated. The most common reasons for not treating TS patients with GH were late diagnosis or GH unavailability. Data on karyotype, parents’ height, puberty development and GH treatment were obtained from their medical records. Adult height was determined when growth velocity was inferior to 1cm/year during a minimum follow-up period of 12 months. Results: The frequency of 45,X karyotype was similar between the groups (48.7% vs. 41.9% in GH-treated vs. GH-untreated TS patients, respectively, P= 0.639). GH-treated TS patients started GH therapy at a chronological age (CA) of 11.2 ± 3.7 yr, bone age of 9.3 ± 3.1 yr, height SDS (British 1965 standards) -3.1 ± 1.1. GH mean dose was 48µg/kg.d and GH treatment duration was 5.4 ± 3.0 yr. Estrogen replacement was started late, at CA of 14.3 ± 2.0 yr in GH-treated and at 14.9 ± 1.9 yr in GH-untreated patients, and the rate of spontaneous puberty was similar between the groups (GH-treated 16.8% vs. GH-untreated 22,8%, P=0.304). Adult height was significantly higher after GH treatment (150.1 ± 5.8 cm vs. 143.3 ± 7.2 cm in GH-treated vs. untreated TS patients, respectively, P &lt; 0.001), even with a small but significant difference in target height between the groups (158.2 ± 4.8 vs. 159.8± 4.5 cm in GH-treated vs. untreated TS patients, respectively, P= 0.015). More than half of the TS GH-treated patients reached normal adult height (equal or higher than 150.2 cm), whereas only 15.6% of GH-untreated patients reached it. Conclusion: Despite the delayed diagnosis of TS patients in our cohort, GH treatment was associated with a significant height gain, and the TS GH-treated group was around 7 cm taller than the GH-untreated group.

AbstractBackground:In recent years, several studies have been published showing different responses to growth hormone (GH) treatment in idiopathic short stature children. The aim of the present study was to investigate whether non-growth-hormone-deficient (non-GHD) short children could benefit from long-term GH treatment as GHD patients.Methods:We enrolled 22 prepubertal children and 22 age- and sex-matched GHD patients, with comparable height, body mass index (BMI), bone age, and insulin-like growth factor 1 (IGF-I) circulating levels. The patients were treated with recombinant human GH (rhGH) and followed until they reach adult height.Results:During GH treatment, the two groups grew in parallel, reaching the same final height-standard deviation score (SDS) and the same height gain. On the contrary, we found significantly lower IGF-I serum concentrations in non-GHD patients than in GHD ones, at the end of therapy (p=0.0055).Conclusions:In our study, the response to GH treatment in short non-GHD patients proved to be similar to that in GHD ones. However, a careful selection of short non-GHD children to be treated with GH would better justify the cost of long-term GH therapy.

AbstractAromatase inhibitors (AIs) have been used to recover height loss due to their capacity to delay growth plate closure. Long-term studies describing final heights are needed to determine the efficacy and safety profiles of these drugs for the treatment of impaired growth. This study aims to identify the therapeutic efficiency of AIs in improve growth and to describe potential adverse effects during treatment. Retrospective data analysis of 96 adolescents, among which 22 patients already attained near-final height, were followed at outpatient clinics of two referral centers. Patients were all in puberty and present idiopathic decrease in predicted adult height. Patients were treated with Anastrozole (ANZ: 1 mg/day) or Letrozole (LTZ: 2.5 mg/day) with/without recombinant human growth hormone (0.05 mg/kg/day) for 1.0 to 3.5 years (2.1±1.2 years). Height gain, body mass index, lipid, liver enzyme, gonadotropins and testosterone levels were described before and at the end of treatment. Predicted adult height (PAH) and NF height were compared with the TH. The height SDS (adjusted to bone age) significantly increased (p<0.05) in all groups [0.8±0.7 (ANZ), 0.7±0.7 (ANZ+GH), 0.3±0.5 (LTZ), and 1.2±0.8 (LTZ+GH)]; the latter group exhibited the highest increment of PAH and growth recovery to the TH (p<0.004). No significant side effects were observed. AI treatment, especially when used in association with GH was able to improve growth and the attainment of familial target height.

ObjectiveThe first year response to growth hormone (GH) treatment is related to the total height gain in GH treated children, but an individual poor first year response is a weak predictor of a poor total GH effect in GH deficient (GHD) children. We investigated whether an underwhelming growth response after 2 years might be a better predictor of poor adult height (AH) outcome after GH treatment in GHD children.Design and methodsHeight data of GHD children treated with GH for at least 4 consecutive years of which at least two prepubertal and who attained (near) (n)AH were retrieved from the Belgian Register for GH treated children (n = 110, 63% boys). In ROC analyses, the change in height (ΔHt) SDS after the first and second GH treatment years were tested as predictors of poor AH outcome defined as: (1) nAH SDS &lt;−2.0, or (2) nAH SDS minus mid-parental height SDS &lt;−1.3, or (3) total ΔHt SDS &lt;1.0. The cut-offs for ΔHt SDS and its sensitivity at a 95% specificity level to detect poor AH outcome were determined.ResultsEleven percent of the cohort had a total ΔHt SDS &lt;1.0. ROC curve testing of first and second years ΔHt SDS as a predictor for total ΔHt SDS &lt;1.0 had an AUC &gt;70%. First-year ΔHt SDS &lt;0.41 correctly identified 42% of the patients with poor AH outcome at a 95% specificity level, resulting in respectively 5/12 (4.6%) correctly identified poor final responders and 5/98 (4.5%) misclassified good final responders (ratio 1.0). ΔHt SDS after 2 prepubertal years had a cut-off level of 0.65 and a sensitivity of 50% at a 95% specificity level, resulting in respectively 6/12 (5.5%) correctly identified poor final responders and 5/98 (4.5%) misclassified good final responders (ratio 1.2).ConclusionIn GHD children the growth response after 2 prepubertal years of GH treatment did not meaningfully improve the prediction of poor AH outcome after GH treatment compared to first-year growth response parameters. Therefore, the decision to re-evaluate the diagnosis or adapt the GH dose in case of poor response after 1 year should not be postponed for another year.
