Age at growth hormone therapy start and first-year responsiveness to growth hormone are major determinants of height outcome in idiopathic short stature.

AIM: To develop methods to identify factors associated with a favorable outcome in GH-treated children with idiopathic short stature (ISS). METHODS: From 4,685 children listed as having ISS within KIGS (Pfizer International Growth Database), we studied (a) the prediction model group (n = 657) to develop the first-year prediction model, and (b) the near adult height group (NAH; n = 256) which received GH for >4 years to develop descriptive models for adult height and overall height gain. RESULTS: NAH group at GH start: age was 10.0 years, height -2.5 SD score (SDS), weight -2.3 SDS, height minus mid-parental height (MPH) -1.5 SDS; GH dose 0.19 mg/kg/week. Height gain was 1.1 SDS at a median age of 17.2 years. Growth response correlated positively with GH dose and weight at the start of GH treatment, and negatively with age and height SDS minus MPH SDS. The model explains 39% (error SD 1.2 cm) of the variability. Adult height correlated (R(2) = 0.64) positively with height at GH start, MPH and the first-year responsiveness to GH, and negatively with age. CONCLUSIONS: Prepubertal children with ISS who show an appropriate first-year response to GH are likely to benefit from long-term treatment, even on low GH dosages.

Insulin-like growth factor-1, leptin, body composition, and clinical status interactions in children with cystic fibrosis.

BACKGROUND/AIMS: Children with cystic fibrosis (CF) are of increased risk of reduced fat body mass (FBM) and lean body mass (LBM). Serum concentrations of insulin-like growth factor-1 (IGF-1)and leptin could be markers of LBM and/or FBM depletion. To evaluate the relationships between disease activity, body composition, IGF-1 and leptin concentrations in CF children. METHODS: A cross-sectional study with 26 CF children aged 5.0-15.5 years and 33 healthy controls, mean age 9.4 years. Body composition was evaluated by dual-energy X-ray absorptiometry. Fasting blood samples were analyzed for leptin, IGF-1 and IGFBP-3. RESULTS: FBM standard deviation score (SDS; CF boys -0.02 +/- 0.88 vs. 0.78 +/- 0.65, p < 0.01; CF girls -0.37 +/- 1.15 vs. 0.70 +/- 0.97, p < 0.05), leptin concentration (CF boys 2.07 +/- 0.79 vs. 3.07 +/- 1.28 ng/ml, p < 0.05; CF girls 2.71 +/- 0.86 vs. 5.00 +/- 2.95 ng/ml, p < 0.05) and IGF-1SDS (CF boys -1.43 +/- 1.50 vs. -0.32 +/- 0.88, p < 0.05; CF girls -0.66 +/- 1.66 vs. 0.64 +/- 0.57, p < 0.01) were lower in CF children compared to controls. Shwachman score was the strongest predictor of lean body mass (R = 0.63). Leptin levels explain 60% of the variability in FBM. CONCLUSION: Serum concentrations of IGF-1 and leptin are decreased in children with CF and are associated with clinical conditions and body composition.

Major determinants of height development in Turner syndrome (TS) patients treated with GH: analysis of 987 patients from KIGS.

Little is known about factors determining height outcome during GH treatment in Turner syndrome (TS). We investigated 987 TS children within the Kabi International Growth Study (KIGS) who had reached near adult height (NAH) after >4 y GH treatment (including >1 y before puberty). Through multiple regression analysis we developed a model for NAH and total gain. Our results were as follows (median): 1) At start, age 9.7 yrs, height (HT) 118.0 cm (0.0 TS SDS), projected adult height 146.1 cm, GH dose 0.27 mg/kg wk; 2) NAH HT 151.0 cm (1.5 TS SDS); 3) Prepubertal gain 21.2 cm (1.6 TS SDS); 4) Pubertal gain 9.4 cm (0.0 TS SDS). NAH correlated (r = 0.67) with (ranked) HT at GH start (+), 1 year responsiveness to GH (+), MPH (+), age at puberty onset (+), age at GH start (-), and dose (+). The same factors explained (R = 0.90) the total HT gain. However, HT at GH start correlated negatively. Karyotype had no influence on outcome. Evidently, height at GH start (the taller, the better), age at GH start (the younger, the better), the responsiveness to GH (the higher, the better) and age at puberty (the later, the better) determine NAH.

Effect of growth hormone (GH) treatment on the near-final height of 1258 patients with idiopathic GH deficiency: analysis of a large international database.

CONTEXT: Treatment with GH has been used to correct the growth deficit in children with GH deficiency (GHD). Although successful in increasing height velocity, such treatment often falls short of helping patients achieve full genetic height potential. OBJECTIVE: This study set out to analyze near-final height (FH) data from a cohort of GH-treated children with idiopathic GHD. DESIGN, SETTING, AND PARTICIPANTS: Of 1258 evaluable patients in the Pfizer International Growth Database (KIGS) with GHD, 980 were of Caucasian origin, and 278 were of Japanese origin; 747 had isolated GHD (IGHD), and 511 had multiple pituitary hormone deficiencies (MPHD). MAIN OUTCOME MEASURES: Near-FH, relation to midparental height, and factors predictive of growth outcomes were the main outcome measures. RESULTS: Median height sd scores (SDS) at the start of treatment were -2.4 (IGHD) and -2.9 (MPHD) for Caucasian males and -2.6 (IGHD) and -3.4 (MPHD) for females, respectively; comparable starting heights were -2.9 (IGHD) and -3.6 (MPHD) for Japanese males and -3.3 (IGHD) and -4.0 (MPHD) for females, respectively. Corresponding near-adult height SDS after GH treatment were -0.8 (IGHD) and -0.7 (MPHD) for Caucasian males and -1.0 (IGHD) and -1.1 (MPHD) for females, respectively; and -1.6 (IGHD) and -1.9 (MPHD) for Japanese males and -2.1 (IGHD) and -1.8 (MPHD) for females, respectively. Differences between near-adult height and midparental height ranged between -0.6 and +0.2 SDS for the various groups, with the closest approximation to MPH occurring in Japanese males with MPHD. The first-year increase in height SDS and prepubertal height gain was highly correlated with total height gain, confirming the importance of treatment before pubertal onset. CONCLUSIONS: It is possible to achieve FH within the midparental height range in patients with idiopathic GHD treated from an early age with GH, but absolute height outcomes remain in the lower part of the normal range. Patients with MPHD generally had a slightly better long-term height outcome.

Effect of gastric bypass on spontaneous growth hormone and ghrelin release profiles.

OBJECTIVE: The purpose of this study was to analyze growth hormone (GH) concentrations in obese women before and after Roux-en-Y gastric bypass (RYGBP) and how resulting changes in weight, fat mass, ghrelin levels, and insulin sensitivity affect GH secretion. RESEARCH METHODS AND PROCEDURES: Blood was sampled at 20-minute intervals for 24 hours in 10 non-diabetic premenopausal severely obese women before and 6 months after RYGBP. GH concentrations were measured in all samples, and serum ghrelin was collected at five time-points. RESULTS: After a 27% BMI drop (55.9 +/- 6.2 to 40.7 +/- 5.8 kg/m2), blunted GH profiles underwent partial recovery. Basal, postprandial, and mean ghrelin concentrations were not changed. A negative correlation was found between mean GH levels and insulin and homeostasis model assessment (p < 0.01). BMI accounted for 54% of GH variation. DISCUSSION: Partial recovery of GH secretion after RYGBP-induced weight loss suggests that a blunted secretion is not a causal factor of obesity but a consequence of the obese state and does not seem to be ghrelin-level dependent.

Recurrence of brain tumours in patients treated with growth hormone: analysis of KIGS (Pfizer International Growth Database).

BACKGROUND: Growth hormone (GH) has been used successfully in the treatment of short stature secondary to GH deficiency in survivors of childhood brain tumours. There has been concern that GH might increase the risk of recurrence. AIM: To analyse KIGS (Pfizer International Growth Database) with respect to tumour recurrence in patients with brain tumours. METHODS: Data for tumour recurrence were analysed retrospectively in 1038 patients with craniopharyngiomas, 655 with medulloblastomas, 113 with ependymomas, 297 with germinomas, and 400 with astrocytomas or gliomas. All patients had received recombinant human GH (Genotropin, Pfizer Inc.). RESULTS: Recurrence-free survival rates were 63% at a follow-up of 10.3 y in craniopharyngioma, 69% in 9.1 y in the glial tumours, 71% in 7.4 y in germinomas, 92% in 4.6 y in medulloblastomas and 89% in 2.5 y in ependymomas. Dose of GH and treatment modalities did not differ significantly between patients with and without recurrence. CONCLUSION: Tumour recurrence rates in surviving patients with brain tumours receiving GH treatment do not appear to be increased compared with published reports. However, longer follow-up regarding recurrences and secondary neoplasms remains essential.

GH secretory pattern in young adults who discontinued GH treatment for GH deficiency and decreased longitudinal growth in childhood.

OBJECTIVE: Some adolescents who discontinue GH treatment due to GH deficiency (GHD) and short stature in childhood do not have classical GHD at retesting in adult life. It is unknown whether there is a neuroendocrine disturbance in the spontaneous pattern of GH release in these patients. DESIGN/PATIENTS/METHODS: Thirty-seven adolescents, who had received treatment with GH due to impaired longitudinal growth, were included. The adolescents were divided into two groups; one (GHD; n = 19) with classical GHD in adult life and another (GH sufficient (GHS); n = 18) without classical adult GHD. One year after GH discontinuation, 24-h GH profiles were performed with blood sampling every 30 min. Sixteen matched healthy controls were also studied. All blood samples were analysed using an ultrasensitive GH assay and then, approximate entropy (ApEn) and deconvolution analysis were performed. RESULTS: The GHD group had higher mean ApEn level than the healthy controls (P < 0.05). As measured by deconvolution analysis, they had lower basal GH secretion (P < 0.01), increased number of GH peaks (P < 0.001), but lower burst mass (P < 0.001), lower percentage pulsatile GH secretion (P < 0.001) and lower total GH secretion (P < 0.001), compared with control subjects. Adolescents in the GHS group had a pattern of 24-h GH release similar to that in healthy controls. CONCLUSION: Young adults with childhood-onset severe GHD have a high-frequency, low-amplitude GH secretion with decreased orderliness. The adolescents without classical GHD in adult life maintain a pattern of spontaneous GH release that is not statistically different from that in the healthy controls.

Increased response, but lower responsiveness, to growth hormone (GH) in very young children (aged 0-3 years) with idiopathic GH Deficiency: analysis of data from KIGS.

In children, GH secretion and sensitivity to GH are influenced by developmental changes. It is not clear whether the response to GH in very young children with GH deficiency (GHD) is the same as that in older, prepubertal children. A cohort of 265 children (180 males and 85 females) with idiopathic GHD from KIGS (Pfizer International Growth Database), with treatment started at less than 3 yr of age (mean age, 1.9 yr; group I) was compared with a cohort of 509 children (331 males and 178 females; group II) with treatment started at 7-8 yr of age (mean age, 7.5 yr). The following differences (P < 0.01) were found (given in mean values) between groups I and II at the start of GH treatment: 9% vs. 5% breech delivery, 38% vs. 14% multiple pituitary hormone deficiency, 4.2 vs. 5.9 ng/ml maximum GH in response to tests, -0.1 vs. -0.8 midparental height (MPH) sd score (SDS), -3.1 vs. -2.5 height SDS, 0.83 vs. 0.66 IU/kg.wk GH dose. After the first year of GH, the results were: 13.3 vs. 8.6 cm/yr height velocity, and 1.7 vs. 0.6 maximum change in height SDS. Using the previously developed growth prediction models for prepubertal children with idiopathic GHD more than 2 yr of age, our analysis revealed differences in the indexes of responsiveness in prediction models (Studentized residuals SDS, 0.7 vs.-0.3) and strikingly higher responsiveness to treatment among the young cohort, but with large scatter. Thus, new prediction models of height velocity (centimeters per year) were derived by means of multiple regression analysis for the young cohort, either involving (model A) or excluding (model B) the GH peak in tests. Model A explained 54% of the total variability with an error sd of 2.1 cm. Height velocity correlated with (parameters in order of importance) age (-), maximum GH (-), GH dose (+), weight SDS (+), height SDS minus MPH SDS (-), and birth weight SDS (+). Model B explained 45% of the total variability with an error sd of 2.3 cm. Height velocity correlated with (parameters in order of importance) age (-), GH dose (+), birth weight SDS (+), height SDS minus MPH SDS (-), and weight SDS (+). The predictors were qualitatively the same as those in the total prepubertal model involving all children more than 2 yr of age, but their quantitative impact in terms of partial contribution and the order of their importance were different for the young cohort. In particular, the partial contribution of the GH dose was higher, suggesting a greater gain in height per GH dose unit in the very young than in the older children. However, the rank order of the GH dose in the new models was lower, which suggests a slightly low sensitivity to GH in toddlers after the phase of severe GH insensitivity during early infancy. The early detection and GH treatment of congenital GHD is advantageous as a cost-effective strategy for achieving greater improvement of absolute height and growth velocity.

Bone age progression during the first year of growth hormone therapy in pre-pubertal children with idiopathic growth hormone deficiency, Turner syndrome or idiopathic short stature, and in short children born small for gestational age: analysis of data from KIGS (Pfizer International Growth Database).

BACKGROUND/AIMS: The beneficial effects of growth hormone (GH) therapy on statural growth in children are well established, but the effects on skeletal maturation are less clear. The progression of bone age (BA) was therefore studied during the first year of GH treatment in pre-pubertal children with idiopathic GH deficiency (GHD), Turner syndrome (TS) or idiopathic short stature (ISS), and in short pre-pubertal children born small for gestational age (SGA). METHODS: Cross-sectional data on 2,209 short children with idiopathic GHD, 694 with TS, 569 with ISS and 153 with SGA were analysed. Longitudinal data were also analysed from 308 children with idiopathic GHD, 99 with TS, 57 with ISS and 29 with SGA. All patients included in the study were enrolled in KIGS (Pfizer International Growth Database) and were being treated with recombinant human GH (Genotropin). BA was assessed using the Greulich and Pyle method at baseline and after 1 year of GH therapy. RESULTS: In all groups of patients the mean progression of BA was 1 year during the year of GH therapy, although there was considerable individual variation. Progression of BA was not correlated with chronological age, BA, height SD score (SDS) or body mass index SDS at the onset of GH therapy. There was also no consistent effect of the GH dose on BA progression. CONCLUSION: Progression of BA appears to be normal in patients receiving GH in these diagnostic groups, at least over the first year of treatment in pre-puberty.

Insulin-like growth factors as diagnostic tools in growth hormone deficiency during childhood and adolescence: the KIGS experience.

Growth hormone (GH) deficiency in children covers a spectrum of disorders involving an impairment in GH secretion and a clinical syndrome characterized by permanent stunting of growth. Ascertaining impairments in GH secretion directly is complex, especially if GH deficiency (GHD) is isolated and not caused by congenital or acquired pituitary defects or genetic abnormalities. It has been established that the concentrations of GH-dependent peptides, such as insulin-like growth factor I (IGF-I) and IGF-binding protein 3 (IGFBP-3), are low in patients with GHD. Their levels are, however, also influenced by a multitude of factors, such as age, gender, height, liver function, nutritional status and other hormones. In addition, the type of complex formed, e.g. either binary or ternary, may influence the measurements of IGFs and their binding proteins. Therefore, levels of IGF-I and IGFBP-3 are generally lower in short children compared with age-matched norms. The reported diagnostic value of sub-normal basal levels of IGF-I and IGFBP-3 is, in terms of sensitivity and specificity, approximately 70%. Thus, definite proof of GHD can only be achieved by means of GH measurements. As the diagnosis of GHD is somewhat unlikely if IGF testing shows normal values, it is clearly advantageous to schedule these tests as part of the initial diagnostic work-up in short children, as their implementation is not only practical but also inexpensive. The Pfizer International Growth Database (KIGS) analysis of IGF-I (n = 2,750) and IGFBP-3 (n = 1,300) levels in children with idiopathic GHD shows that these two parameters are now firmly embedded in diagnostic strategies around the world.

Growth in early life and its relation to pubertal growth.

BACKGROUND: The timing and magnitude of pubertal growth in relation to fetal, infancy and childhood growth have not been explored. METHODS: We used data from a longitudinal growth study of 3650 full-term healthy children who were born in Gothenburg, Sweden in 1973-1975. This analysis included 2738 children with height and weight measurements available both in early life and during adolescence. RESULTS: We found that faster linear growth during infancy and childhood was associated with earlier peak height velocity during adolescence. In contrast, greater height and body mass index (BMI) at birth were associated with later peak height velocity in adolescence. Children with faster linear growth and greater BMI in infancy and childhood had less height gain between ages 8 and 18. However, greater height and BMI at birth were associated with more height gain between ages 8 and 18 after adjusting for height and BMI in childhood. CONCLUSIONS: Both length and BMI (at birth, in infancy and during childhood) are associated with the timing and magnitude of pubertal growth. Being small at birth is associated with early puberty and a reduced height gain during adolescence.

Pubertal growth assessment.

Almost all available sets of height growth reference values are constructed in a cross-sectional manner, except for a few studies in which longitudinal sampling was used. Such reference values are, however, flawed because of considerable individual variation in the timing of puberty, especially among children with early or late pubertal maturation. An additional complicating factor is that the magnitude of the total pubertal growth spurt is significantly larger among those individuals with early pubertal maturation, compared with late maturation. Based on the growth records of 145 healthy Swedish children followed longitudinally, this study introduces a pre-pubertal standard for the assessment of pre-pubertal height for children with late onset of puberty. By plotting the height values of a child in a chart containing pre-pubertal reference values, the onset of the pubertal growth spurt can be identified by a change in the pre-pubertal height standard deviation score values of 0.3 standard deviations or more over a period of 1 year. Once the pubertal onset is established, a highly accurate final height prediction method can be applied to the data, as described in this article, in which height and age at pubertal onset are the only two measures required. The r(2) value of the prediction model was over 0.80 for both sexes. Finally, a method for assessing total pubertal height gain is presented. The method adjusts for the timing of puberty and is based on the height and age at pubertal onset, plus the observed final height.

The KIGS experience with the addition of gonadotropin-releasing hormone agonists to growth hormone (GH) treatment of children with idiopathic GH deficiency.

Although recombinant techniques have enabled the production of limitless amounts of human growth hormone (GH), and clinical methods for diagnosis and treatment have been greatly enhanced, the mean final heights of children with idiopathic GH deficiency (IGHD) treated with GH remain in the range of -1.3 standard deviation scores (SDS) below normal height. One of the methods used to increase height outcomes is to delay the onset and progression of puberty to allow for a longer 'pre-pubertal' growth phase. We reviewed the KIGS (Pharmacia International Growth Database) data of patients with IGHD who had been treated with gonadotropin-releasing hormone agonists (GnRHa) in order to see if a greater gain in height could be achieved by altering the tempo of pubertal maturation. Near-final height data were analysed in 39 adolescents (out of a total of 249) who had received GH + GnRHa therapy and were compared with similar data from 1,893 patients with IGHD treated with GH alone. The total change in height SDS in boys who received GH alone was +1.6, in contrast to +1.1 in GH + GnRHa-treated boys; the total change in height SDS in girls who received GH alone was +1.4 in contrast to +1.1 in girls treated with GH + GnRHa. The near final height SDS in girls treated with GH + GnRHa was 1.0 below the mid-parental target height (MPH), whereas there was only a -0.5 SDS difference in girls treated with GH. Approximation to the MPH did not differ in boys between the two treatment groups. These data suggest that the attainment of a substantial height SDS by manipulating the tempo of puberty is limited, but that optimizing growth during the pre-pubertal phase is a more important factor.

The mathematical model for total pubertal growth in idiopathic growth hormone (GH) deficiency suggests a moderate role of GH dose.

The role of GH treatment during total pubertal growth (TPG) is still unclear. We developed a prediction model for TPG (centimeters) through a multiple regression analysis of various prepubertal parameters in 303 adolescents with idiopathic GH deficiency from the KIGS database. Prepubertal catch-up growth and near-adult height were achieved, and GH dose was kept constant at approximately 30 micro g/kg.d. The model was validated on a cohort of 36 patients from one center. Four TPG predictors explained 70% of the variability with an error SD of 4.2 cm: gender (TPG in males was >11.3 cm vs. that in females), age at onset of puberty (negative), height SD score minus midparental height SD score at puberty onset (negative), and mean GH dose during puberty (positive). Our analysis suggests that TPG in idiopathic GH deficiency is only moderately dependent on GH dose. The use of a higher GH dosage at the onset of puberty should thus depend on the individual's height development. The TPG model aids in the planning of individually optimized and cost-effective GH treatment.

Short-term gluten challenge in children with coeliac disease does not impair spontaneous growth hormone secretion.

BACKGROUND: Growth retardation in children with coeliac disease has been attributed to impaired growth hormone (GH) secretion observed in stimulation tests. OBJECTIVE: This study aimed at investigating the possible change in spontaneous GH secretion during a standardised gluten challenge. PATIENTS: Twelve children with previous enteropathy suggesting coeliac disease and a normal pre-challenge biopsy on a gluten-free diet were included; eight of them completed all parts of the study, including repeated 24-h GH sampling. METHODS: At the start and the end of a 5-6 weeks standardised gluten challenge, blood was drawn at a constant rate for 24 h and collected for GH analysis at 20-min intervals. The graph of plotted GH values was analysed by means of a computer program (PULSAR). RESULTS: No significant changes were seen in the measures of maximum GH peak, baseline GH values, area under the curve over the baseline (AUCb), the number of GH peaks or mean GH concentration. GH secretion rate (GHt) increased slightly. None of the characteristics of the 24-h profile was significantly correlated to the change of IGF-I. CONCLUSION: No impaired GH secretion was found. Thus, we speculate that decreased growth rate in celiac disease may not be primarily caused by changes in GH secretion. Instead it may be caused by changed peripheral sensitivity to GH.

Postnatal serum insulin-like growth factor I deficiency is associated with retinopathy of prematurity and other complications of premature birth.

OBJECTIVE: Insulin-like growth factor I (IGF-I) is necessary for normal development of retinal blood vessels in mice and humans. Because retinopathy of prematurity (ROP) is initiated by abnormal postnatal retinal development, we hypothesized that prolonged low IGF-I in premature infants might be a risk factor for ROP. DESIGN: We conducted a prospective, longitudinal study measuring serum IGF-I concentrations weekly in 84 premature infants from birth (postmenstrual ages: 24-32 weeks) until discharge from the hospital. Infants were evaluated for ROP and other morbidity of prematurity: bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), and necrotizing enterocolitis (NEC). RESULTS: Low serum IGF-I values correlated with later development of ROP. The mean IGF-I +/- SEM level during postmenstrual ages 30-33 weeks was lowest with severe ROP (25 +/- 2.41 micro g/L), 29 +/- 1.76 micro g/L with moderate ROP, and 33 +/- 1.72 micro g/L with no ROP. The duration of low IGF-I also correlated strongly with the severity of ROP. The interval from birth until serum IGF-I levels reached >33 micro g/L was 23 +/- 2.6 days for no ROP, 44 +/- 4.8 days for moderate ROP, and 52 +/- 7.5 days for severe ROP. Each adjusted stepwise increase of 5 micro g/L in mean IGF-I during postmenstrual ages 30 to 33 weeks decreased the risk of proliferative ROP by 45%. Other complications (NEC, BPD, IVH) were correlated with ROP and with low IGF-I levels. The relative risk for any morbidity (ROP, BPD, IVH, or NEC) was increased 2.2-fold (95% confidence interval: 1.41-3.43) if IGF-I was <or=33 micro g/L at 33 weeks' postmenstrual age. CONCLUSIONS: These results indicate that persistent low serum concentrations of IGF-I after premature birth are associated with later development of ROP and other complications of prematurity. IGF-I is at least as strong a determinant of risk for ROP as postmenstrual age at birth and birth weight.

[A child's growth mirrors health and illness. Regular measurement of body height is an important diagnostic tool].

The growth of children is an important health indicator. In the individual child, growth mirrors health or illness. At the child population level, growth may be used to monitor living conditions. Continued deviations may indicate somatic disorders or psychosocial problems. The assessment of the growth of an individual child is complicated due to the difficulty to measure children. Thus, the height of the child will have to deviate substantially from that of the reference population before action is called for. The progress over time of the child's growth, on the other hand, is a much more sensitive indicator of ill health than is the height of the child at a certain age. Systematic assessment of each measuring may serve as an aid to detect abnormal growth and thereby facilitate a correct diagnosis.
