Measurement of dijet production at low Q(2) at HERA
- 2004
-
In: European Physical Journal C. Particles and Fields. - : Springer Science and Business Media LLC. - 1434-6044. ; 37:2, s. 141-159

Journal article (peer-reviewed)abstract
- Triple differential dijet cross sections in e(+/-)p interactions are presented in the region of photon virtualities 2 < Q(2) < 80 GeV2, inelasticities 0.1 < y < 0.85, jet transverse energies E*(T1) > 7GeV, E*(T2) > 5 GeV, and pseudorapidities - 2.5 < η(1)*, η(2)* < 0. The measurements are made in the gamma*p centre-of-mass frame, using an integrated luminosity of 57 pb(-1). The data are compared with NLO QCD calculations and LO Monte Carlo programs with and without a resolved virtual photon contribution. NLO QCD calculations fail to describe the region of low Q(2) and low jet transverse energies, in contrast to a LO Monte Carlo generator which includes direct and resolved photon interactions with both transversely and longitudinally polarised photons. Initial and final state parton showers are tested as a mechanism for including higher order QCD effects in low E-T jet production.

- 2022
-
In: Journal of Clinical Endocrinology & Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 107:12, s. 3287-3301

Journal article (peer-reviewed)abstract
- Context The Kabi/Pfizer International Growth Database (KIGS) is a large, international database (1987-2012) of children treated with recombinant human growth hormone (rhGH) in real-world settings. Objective This work aimed to evaluate the safety and efficacy of rhGH from the full KIGS cohort. Methods Data were collected by investigators from children with growth disorders treated with rhGH (Genotropin [somatropin]; Pfizer). Safety was evaluated in all treated patients, and efficacy in those treated for 1 year or more. A subgroup included patients treated for 5 years or more (>= 2 years prepubertal) who had reached near-adult height (NAH). Main outcomes included 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-SD score (SDS) (Prader) in prepubertal patients was 0.66 (IGHD), 0.55 (ISS), 0.58 (TS), and 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.

Recommendations for the diagnosis and management of Turner syndrome.
- 2001
-
In: The Journal of clinical endocrinology and metabolism. - : The Endocrine Society. - 0021-972X. ; 86:7, s. 3061-9
-
Journal article (peer-reviewed)abstract
- Comprehensive recommendations on the diagnosis of Turner syndrome (TS) and the care of affected individuals were published in 1994. In the light of recent advances in diagnosis and treatment of TS, an international multidisciplinary workshop was convened in March 2000, in Naples, Italy, in conjunction with the Fifth International Symposium on Turner Syndrome to update these recommendations. The present paper details the outcome from this workshop. The genetics and diagnosis of the syndrome are described, and practical treatment guidelines are presented.

Optimal Pubertal Induction in Girls with Turner Syndrome Using Either Oral or Transdermal Estradiol: A Proposed Modern Strategy
- 2019
-
In: Hormone Research in Paediatrics. - : S. Karger AG. - 1663-2818 .- 1663-2826. ; 91:3, s. 153-163
-
Journal article (peer-reviewed)abstract
- Background: Most girls with Turner syndrome (TS) require pubertal induction with estrogen, followed by long term replacement. However, no adequately powered prospective studies comparing transdermal with oral 17 beta-estradiol administration exist. This reflects the difficulty of securing funding to study a rare condition with relatively low morbidity/mortality when competing against conditions such as cancer and vascular disease. Protocol Consensus: The TS Working Group of the European Society for Paediatric Endocrinology (ESPE) has agreed to both a 3-year oral and a 3-year transdermal regimen for pubertal induction. Prerequisites include suitable 17 beta-estradiol tablets and matrix patches to allow the delivery of incremental doses based on body weight. Study Proposal: An international prospective cohort study with single centre analysis is proposed in which clinicians and families are invited to choose either of the agreed regimens, usually starting at 11 years. We hypothesise that pubertal induction with transdermal estradiol will result in better outcomes for some key parameters. The primary outcome measure chosen is height gain during the induction period. Analysis: Assessment of the demographics and drop-out rates of patients choosing either oral or transdermal preparations; and appropriate analysis of outcomes including pubertal height gain, final height, liver enzyme and lipid profile, adherence/acceptability, cardiovascular health, including systolic and diastolic blood pressure and aortic root diameter and bone health. Conclusion: The proposed model of prospective data collection according to internationally agreed protocols aims to break the current impasse in obtaining evidence-based management for TS and could be applied to other rare paediatric endocrine conditions.

Growth hormone treatment and adverse events in Prader-Willi syndrome: data from KIGS (the Pfizer International Growth Database)
- 2006
-
In: Clin Endocrinol (Oxf). ; 65:2, s. 178-85
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: To evaluate the response to recombinant GH treatment and adverse events in children with Prader-Willi syndrome (PWS) from KIGS, the Pfizer International Growth Database. PATIENTS: A total of 328 children (274 prepubertal, median age 6.0 years; 54 pubertal, median age 12.7 years) were treated for 1 year and 161 children were treated for 2 years with GH. RESULTS: Height standard deviation score (SDS) increased significantly during treatment; the response was greater in prepubertal (-0.7 vs.-1.8 pretreatment) compared with pubertal children (-1.5 vs.-1.8). Predictors of first-year height velocity in multiple regression analysis were GH dose, body weight (positively correlated), height SDS minus mid-parental height SDS and chronological age (negatively correlated), together accounting for 39% of the variation in response to GH. Body mass index (BMI) SDS did not change significantly during 2 years of treatment. Of all the 675 GH-treated PWS patients in KIGS, there were five cases of sudden death (age range 3-15 years). Three were obese (weight for height > 200%) and causes of death included bronchopneumonia, respiratory insufficiency and sleep apnoea. Scoliosis was the most commonly reported adverse event (n = 24), four children developed hyperglycaemia and six had presumptive diabetes (type 2 in five, and one case of type 1). CONCLUSIONS: Short-term growth improved in response to conventional doses of GH in children with PWS. Prior to commencement of GH, examination of the upper airways and sleep studies should be performed in PWS patients. GH should be used with caution in those with extreme obesity or disordered breathing and all patients should be closely monitored for adverse events.

A Genome-Wide Pharmacogenetic Study of Growth Hormone Responsiveness
- 2020
-
In: The Journal of clinical endocrinology and metabolism. - : The Endocrine Society. - 1945-7197 .- 0021-972X. ; 105:10, s. 3203-3214
-
Journal article (peer-reviewed)abstract
- CONTEXT: Individual patients vary in their response to growth hormone (GH). No large-scale genome-wide studies have looked for genetic predictors of GH responsiveness. OBJECTIVE: To identify genetic variants associated with GH responsiveness. DESIGN: Genome-wide association study (GWAS). SETTING: Cohorts from multiple academic centers and a clinical trial. PATIENTS: A total of 614 individuals from 5 short stature cohorts receiving GH: 297 with idiopathic short stature, 276 with isolated GH deficiency, and 65 born small for gestational age. INTERVENTION: Association of more than 2 million variants was tested. MAIN OUTCOME MEASURES: Primary analysis: individual single nucleotide polymorphism (SNP) association with first-year change in height standard deviation scores. Secondary analyses: SNP associations in clinical subgroups adjusted for clinical variables; association of polygenic score calculated from 697 genome-wide significant height SNPs with GH responsiveness. RESULTS: No common variant associations reached genome-wide significance in the primary analysis. The strongest suggestive signals were found near the B4GALT4 and TBCE genes. After meta-analysis including replication data, signals at several loci reached or retained genome-wide significance in secondary analyses, including variants near ST3GAL6. There was no significant association with variants previously reported to be associated with GH response nor with a polygenic predicted height score. CONCLUSIONS: We performed the largest GWAS of GH responsiveness to date. We identified 2 loci with a suggestive effect on GH responsiveness in our primary analysis and several genome-wide significant associations in secondary analyses that require further replication. Our results are consistent with a polygenic component to GH responsiveness, likely distinct from the genetic regulators of adult height. © Endocrine Society 2020.

Personalized Approach to Growth Hormone Treatment: Clinical Use of Growth Prediction Models
- 2013
-
In: Hormone Research in Paediatrics. - : Karger. - 1663-2818 .- 1663-2826. ; 79:5, s. 257-270
-
Research review (peer-reviewed)abstract
- The goal of growth hormone (GH) treatment in a short child is to attain a fast catch-up growth toward the target height (TH) standard deviation score (SDS), followed by a maintenance phase, a proper pubertal height gain, and an adult height close to TH. The short-term response variable of GH treatment, first-year height velocity (HV) (cm/year or change in height SDS), can either be compared with GH response charts for diagnosis, age and gender, or with predicted HV based on prediction models. Three types of prediction models have been described: the Kabi International Growth Hormone Study models, the Gothenburg models and the Cologne model. With these models, 50-80% of the variance could be explained. When used prospectively, individualized dosing reduces the variation in growth response in comparison with a fixed dose per body weight. Insulin-like growth factor-I-based dose titration also led to a decrease in the variation. It is uncertain whether adding biochemical, genetic or proteomic markers may improve the accuracy of the prediction. Prediction models may lead to a more evidence-based approach to determine the GH dose regimen and may reduce the drug costs for GH treatment. There is a need for user-friendly software programs to make prediction models easily available in the clinic.

Diagnosis, Genetics, and Therapy of Short Stature in Children : A Growth Hormone Research Society International Perspective
- 2019
-
In: Hormone Research in Paediatrics. - : S. Karger. - 1663-2818 .- 1663-2826. ; 92:1, s. 1-14
-
Journal article (peer-reviewed)abstract
- The Growth Hormone Research Society (GRS) convened a Workshop in March 2019 to evaluate the diagnosis and therapy of short stature in children. Forty-six international experts participated at the invitation of GRS including clinicians, basic scientists, and representatives from regulatory agencies and the pharmaceutical industry. Following plenary presentations addressing the current diagnosis and therapy of short stature in children, breakout groups discussed questions produced in advance by the planning committee and reconvened to share the group reports. A writing team assembled one document that was subsequently discussed and revised by participants. Participants from regulatory agencies and pharmaceutical companies were not part of the writing process. Short stature is the most common reason for referral to the pediatric endocrinologist. History, physical examination, and auxology remain the most important methods for understanding the reasons for the short stature. While some long-standing topics of controversy continue to generate debate, including in whom, and how, to perform and interpret growth hormone stimulation tests, new research areas are changing the clinical landscape, such as the genetics of short stature, selection of patients for genetic testing, and interpretation of genetic tests in the clinical setting. What dose of growth hormone to start, how to adjust the dose, and how to identify and manage a suboptimal response are still topics to debate. Additional areas that are expected to transform the growth field include the development of long-acting growth hormone preparations and other new therapeutics and diagnostics that may increase adult height or aid in the diagnosis of growth hormone deficiency.

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)
- 2005
-
In: Horm Res. ; 63:1, s. 40-7
-
Journal article (peer-reviewed)abstract
- 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((R))). 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. Copyright (c) 2005 S.

The Use of Bone Age in Clinical Practice - Part 1
- 2011
-
In: Hormone Research in Paediatrics. - : S. Karger AG. - 1663-2818 .- 1663-2826. ; 76:1, s. 1-9
-
Journal article (peer-reviewed)abstract
- This review examines the role of skeletal maturity ('bone age', BA) assessment in clinical practice. BA is mainly used in children with the following conditions: short stature (addressed in part 1 of this review), tall stature, early or late puberty, and congenital adrenal hyperplasia (all addressed in part 2). Various manual and automatic methods of BA assessment have been developed. Healthy tall children tend to have advanced BA and healthy short children tend to have delayed BA in comparison to chronological age. Growth hormone (GH) treatment of children with GH deficiency leads to a catch-up in BA that is usually appropriate for the height of the child. Response to GH is dependent on BA delay in young children with idiopathic short stature, and GH dosage appears to affect BA acceleration. In chronic renal failure, BA is delayed until puberty but then increases due to increased sensitivity of the growth plate to sex steroids, thus further impairing adult height. The assessment of BA provides an important contribution to the diagnostic workup and management of children with short stature.

Major determinants of height development in Turner syndrome (TS) patients treated with GH: analysis of 987 patients from KIGS
- 2007
-
In: Pediatr Res. - : Springer Science and Business Media LLC. - 0031-3998. ; 61:1, s. 105-10
-
Journal article (peer-reviewed)abstract
- 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.

Age at Growth Hormone Therapy Start and First-Year Responsiveness to Growth Hormone Are Major Determinants of Height Outcome in Idiopathic Short Stature
- 2007
-
In: Horm Res. - : S. Karger AG. - 0301-0163. ; 68:2, s. 53-62
-
Journal article (peer-reviewed)abstract
- 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. Copyright (c) 2007 S.

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
- 2005
-
In: J Clin Endocrinol Metab. ; 90:4, s. 1966-71
-
Journal article (peer-reviewed)abstract
- 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.

Insulin-like growth factors as diagnostic tools in growth hormone deficiency during childhood and adolescence: the KIGS experience
- 2004
-
In: Horm Res. ; 62 Suppl 1, s. 17-25
-
Journal article (peer-reviewed)abstract
- 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.

Effect of Growth Hormone (GH) Treatment on the Final Height of 1258 Patients with Idiopathic GH Deficiency: Analysis of a Large International Database
- 2006
-
In: The Journal of Clinical Endocrinology & Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 91:6, s. 2047-2054
-
Journal article (peer-reviewed)abstract
- Context: Treatment with growth hormone (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 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 of Japanese origin; 747 had isolated GHD (IGHD), while 511 had multiple pituitary hormone deficiencies (MPHD). Main Outcome Measures: Near final height, relation to midparental height, and factors predictive of growth outcomes. Results: Median height SD scores (SDS) at 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 different groups, with the closest approximation to MPH occurring in Japanese males with MPHD. First-year increase in height SDS and prepubertal height gain were highly correlated with total height gain confirming importance of treatment before pubertal onset. Conclusions: It is possible to achieve final height 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.
