Patients' Perception of the Use of the EasyPod™ Growth Hormone Injector Device and Impact on Injection Adherence: A Multi-Center Regional Study. Front Pediatr 2022; 10:839278. [PMID: 35295698 PMCID: PMC8918687 DOI: 10.3389/fped.2022.839278] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Accepted: 01/31/2022] [Indexed: 12/05/2022] Open
Abstract
OBJECTIVE This study aimed to assess patient perceptions of the use of the EasyPod™ growth hormone delivery device and its association with compliance. METHODS This cross-sectional, multicenter study was conducted in six centers from three countries (United Arab Emirates, Oman, and Saudi Arabia,) between March 2020 and June 2020. Children and adolescents aged 3-18 years, diagnosed with growth disorders and receiving rhGH through the EasyPod™ device were enrolled. Patients and caregivers were given a pre-set questionnaire that evaluated patient satisfaction, preference for technical and personalized features, and device drawbacks. The results were analyzed using independent measures of analysis of variance to evaluate the association of higher satisfaction with device features and better compliance. RESULTS A total of 186 patients were enrolled in the study. Of these, 45.7% had GH deficiency. The mean age (±SD) of patients was 11.8 (±2.76) years; 117 (62.90%) were males. Average compliance was 87%. One hundred patients (53.76%) had injection compliance of ≥90%. Amongst these patients, 74%, 68%, and 77% top-scored (5/5) the technical features of hidden needle, skin sensor, and pre-set dosing, respectively, compared to top scores by 39%, 34%, and 51% patients in the <90% compliance group (p-value <0.05). Similarly, a statistically significant difference was observed between the groups (p-value <0.05) in the perception of the usefulness of the tracking features such as display of history of injected doses (78% vs. 47.7%), a reminder for medicine remaining (46% vs. 23.3%) and battery power indicator (48% vs. 20.9%). Personal screen messages were associated with higher compliance while the requirement to keep the device in the fridge was reported as the most inconvenient feature by 56% of patients in the higher compliance group as against 39.5% in the lower compliance group (p-value <0.05). There was no statistically significant difference in the intensity of pain reported in the two compliance groups. CONCLUSION Our study showed that there is a statistically significant association between better perception of device features and higher compliance.

Investigating the Impact of the TUITEK ® Patient Support Programme, Designed to Support Caregivers of Children Prescribed Recombinant Human Growth Hormone Treatment in Taiwan. Front Endocrinol (Lausanne) 2022; 13:897956. [PMID: 35600589 PMCID: PMC9120661 DOI: 10.3389/fendo.2022.897956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 04/07/2022] [Indexed: 11/13/2022] Open
Abstract
PURPOSE Poor adherence to recombinant human growth hormone (r-hGH) treatment presents a significant barrier to achieving optimal growth outcomes. It is important to identify and address the treatment adherence-related needs of children prescribed r-hGH treatment, and develop new approaches to improve adherence. We aimed to measure the impact of the TUITEK® patient support programme, a multi-component personalized service intervention, on caregivers' knowledge, beliefs, and perceptions of short stature and adherence to its treatment. PATIENTS AND METHODS The evaluation of the TUITEK® patient support programme was conducted among 31 caregivers of children with short stature and receiving r-hGH treatment via the easypod™ auto-injector device in Taiwan. Caregivers within the 'high risk' category for knowledge, beliefs and perception factors influencing adherence to r-hGH treatment (disease and treatment coherence, emotional burden, self-administration, and treatment-related anxiety) were identified via the TUITEK® personalization questionnaire and followed up with bi-weekly telephone calls by a nurse practitioner over a 3-month period. A Wilcoxon signed-rank test was used to compare changes in questionnaire-based scoring patterns between baseline and follow-up. RESULTS Between baseline and follow-up, the percentage of caregivers scoring as 'high risk' for emotional burden reduced by 37%; there was an improvement in confidence of self-administration by 57% and the percentage of caregivers scoring as 'high risk' for treatment-related anxiety reduced by 52%. At follow-up, all caregivers classified as 'high risk' within the disease and treatment coherence item at baseline moved into the 'low risk' category. Statistically significant changes in questionnaire scores between baseline and follow-up for disease and treatment understanding, emotional burden, self-administration, and treatment-related anxiety were also observed. CONCLUSION These findings indicate that the TUITEK® patient support programme can positively address disease and treatment-related barriers amongst caregivers regarding optimal adherence of their children to r-hGH treatment, which has the potential to positively impact on adherence levels and patient clinical health outcomes.

Lack of Catch-Up Growth with Growth Hormone Treatment in a Child Born Small for Gestational Age Leading to a Diagnosis of Noonan Syndrome with a Pathogenic PTPN11 Variant. Case Rep Endocrinol 2021; 2021:5571524. [PMID: 34194850 PMCID: PMC8203378 DOI: 10.1155/2021/5571524] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 05/27/2021] [Indexed: 11/30/2022] Open
Abstract
Background Growth hormone (GH) treatment increases the adult height of short children born small for gestational age (SGA). Catch-up growth is associated with a younger age, shorter height, and prepubertal status at the onset of GH treatment. We report a 12 11/12-year-old girl born SGA who received GH for 5 years without catch-up growth and was diagnosed with Noonan Syndrome (NS). Results A 5-year-and-9-month-old 46, XX girl born SGA was started on GH treatment at a dose of 0.32 mg/kg/week. Her midparental target height is 158.6 cm. Endocrine work up showed an IGF-1 level 69 ng/ml (Normal (N): 55–238 ng/ml), IGFBP3 2.6 mg/L (N: 1.9–5.2 mg/L), TSH 3.2 mIU/L (N: 0.35–5.5 mIU/L), and a normal skeletal survey. Height was 96 cm (0.1%; Ht SDS −2.9), weight 14 kgs (1%; Wt SDS −2.3), and Tanner 1 breast and pubic hair were observed. Due to the poor catch-up growth on GH treatment, she was referred to Genetics to elucidate genetic or syndromic causes of short stature. She was noted to have posteriorly rotated ears and slight down slanting of the palpebral fissures. Genetic findings showed a heterozygous pathogenic variant in PTPN11 (c.922A > G (p.Asn308Asp)) diagnostic for NS. This finding is de novo given negative parental testing. She was noted to have a heterozygous missense variant of unknown significance (VUS) in FGFR3: c.746C > A (p.Ser249Tyr). FGFR3 is associated with multiple skeletal dysplasias including thanatophoric dysplasia, achondroplasia, and Crouzon syndrome and hypochondroplasia. Clinical correlation is poor for these syndromes. Conclusion Diminished catch-up growth and response to GH treatment in a child born SGA led to the diagnosis of NS. The concomitant diagnosis of SGA and NS may have affected the responsiveness of this child to the growth promoting effect of GH treatment.

Abstract
Objective: To assess a decade of growth hormone (GH) treatment patterns and outcomes in a real-world setting in Israel using a state-of-the-art computerized database. Methods: This large retrospective database study included 2,379 children initiating GH treatment in Maccabi Healthcare Services (between January 2004 and December 2014). Good adherence with therapy (proportion of days covered >80%) was assessed during follow-up. Results: At GH treatment initiation: 62.1% were boys; height standard deviation score (SDS) was -2.36 ± 0.65 (mean ± SD); age was 9.8 ± 3.1 years; and time from short stature diagnosis to first GH purchase was 4.8 ± 3.3 years. Mean treatment period was 3.5 ± 0.95 years; 79.4% of children were treated for more than 3 years. The two main indications for GH therapy were idiopathic short stature (ISS) (n = 1,615, 67.9%) and GH deficiency (GHD) (n = 611, 25.7%). Children in the highest socio-economic-status (SES) tertile comprised 61.3% of ISS and 59.7% of GHD. After 3 years, mean height gain SDS was 1.09 ± 0.91 for GHD and 0.96 ± 0.57 for ISS (p = 0.0004). Adult height (age 15 for girls and 17 for boys) was recorded for 624 patients (26.2%) with better outcomes for GHD than ISS (-1.0±0.82 vs. -1.28±0.93, respectively; p = 0.0002). Good adherence was achieved in 78.2% of the cohort during the first year and declined thereafter to 68.1% during the third year of the treatment. Conclusions: Children who initiate GH therapy are predominantly male, belong mainly to the upper SES, commence treatment a long period after initial recognition of short stature, and have suboptimal adherence. Appropriate referral, diagnosis, and follow-up care may result in better treatment outcomes with GH therapy.

Abstract
Short stature, ovarian dysgenesis, infertility, and cardiovascular malformations are classic features in Turner syndrome (TS), but the phenotypical spectrum is wide. Through early diagnosis and appropriate treatment, TS patients have a chance to achieve satisfactory adult height and sexual development. The doses of recombinant growth hormone (rGH) used are usually higher than the substitution dose. The safety aspects of this therapy are very important, especially in terms of the cardiovascular system. The presented study aimed to analyze how the rGH therapy may influence the cardiovascular system in TS based on current literature data. We conducted a systematic search for studies related to TS, cardiovascular system, and rGH therapy. The results show that rGH seems to have a positive effect on lipid parameters, reducing the risk of ischemic disease. It is additionally optimized by estradiol therapy. Although rGH may increase insulin resistance, the metabolic derangement is rare, probably due to lower fat content and an increase in lean body mass. Several studies showed that rGH treatment could cause aorta widening or increase the aorta growth rate. IGF-1 can be independently associated with increased aortic diameters. The studies analyzing the impact of GH on blood pressure show conflicting data. The proper cardiovascular imaging before and during rGH treatment and detecting the known risk factors for aorta dissection in every individual is very important. The long-term effects of growth hormone treatment on the heart and arteries are still not available and clearly estimated and have to be monitored in the future.

Abstract
PURPOSE To achieve understanding of the meanings of mothers' experiences of caring for children receiving growth hormone treatment (GHT). BACKGROUND Children generally begin GHT at a very early age which means parents have significant responsibilities and often endure a complex and difficult pathway with GHT. DESIGN AND METHODS Hermeneutic interpretive phenomenology based on the approach of Gadamer that adhered to the consolidated criteria for reporting qualitative research (COREQ) guidelines. See Supplementary File 1. Data collected through interviews and diaries with mothers (n = 16). RESULTS Mothers' experiences were framed by three concepts: uncertainty, normalisation and stigma. These concepts were used to elaborate on the four major meanings encapsulating their experience of caring for their children receiving GHT: (1) "It's the right thing to do" (Striving for the security and the wellbeing of the child), (2) "Doubting yourself constantly" (Constant uncertainty), (3) "But then you just get used to it I suppose" (Adhering to GHT and lifestyle changes - the new normal), (4) "I hadn't been told anything about it" (Information behaviour; looking for normality and certainty). CONCLUSION Mothers experienced significant challenges coping with the uncertainties associated with GHT and needed more information and support. The felt stigma of restricted growth, rare medical condition and GHT appeared to hinder some mothers from seeking support. PRACTICE IMPLICATIONS Healthcare professionals and policy makers need to ensure that services for children receiving GHT include the necessary continuous practical and emotional support for parents along the treatment journey.

Abstract
OBJECTIVE Adherence to treatment regimen is a key factor in the success of Growth Hormone (GH) therapy. Our objective was to assess the long time adherence to treatment in a large cohort of patients. DESIGN It is a retrospective study. The data was collected from a single central computerized data center well maintained and checked for quality. All patient aged 1-16 years, treated with GH during 2006-2015 for >2 years, who were insured by "Clalit" Health Maintenance Organization. Adherence was measured by the number of months of pharmacy purchased GH annually: good (11-12), moderate (7-10), and poor (<7) months per year. RESULTS 2263 patients (59% males) were treated for >2 years. Mean age at treatment initiation was 8.3 ± 3.6 years, 74% were secular Jews, 6.8% ultra-religious Jews and 18.9% of Arab origin. Only 30% of patients had good adherence to GH therapy. Patients who started treatment before age 8 years had poorest adherence rate. No association was found between adherence to GH therapy and gender or socioeconomic status. In a multivariate analysis (gender, age groups, ethnicity and clinic SES) we found the ultra-religious population had higher risk for non adherence (OR 2.16, CI 95% 1.46-3.19). The poorest adherence by age was in the youngest patients. In patients treated for >5 years (n = 668), adherence rate declined slightly over the years. CONCLUSIONS Long term adherence to GH therapy is suboptimal. Measures for improving adherence especially among younger and ultra- religious patients are needed.

Abstract
Despite the long-held belief that growth hormone supplementation provides psychosocial benefits to patients with Turner syndrome (TS), this assumption has never been rigorously tested in a randomized control trial. As a sub-study of the Canadian growth-hormone trial, parent-, and patient-completed standardized questionnaires were used to compare 70 girls with TS who received injections (GH group) and 61 similarly followed untreated TS controls (C) on multiple facets of psychosocial functioning. Questionnaires were given (i) at baseline (session 1, mean age = 10.4 y), (ii) before estrogen therapy for puberty induction (session 2, mean age = 13.0 y), (iii) after 1 year of estrogen therapy (session 3, mean age = 14.4 y), and (iv) when growth stopped (session 4, mean age = 16.3 y). Groups were compared for multiple facets of psychosocial function within social, behavioral, self-esteem, and academic domains. Results were also correlated with indices of adult height. We found no global (i.e., across-session) group differences on any scales or subscales of the four domains. In both GH and C groups, age-related improvements were seen for social problems, externalizing behavior problems, and school functioning and age-related declines for social competence and social relations. Both parents and patients claimed GH received less teasing than C but C had more friends than GH. Results from analyses conducted within individual sessions showed that while GH at early sessions claimed to be more popular, more socially engaged, better adapted, and to have higher self-esteem than C, C was reported to be less anxious, depressed, and withdrawn than GH at adult height. The correlation analyses revealed different effects of adult height and height gain on outcome for the two groups. In GH, both height parameters were correlated with multiple parent- and/or self-reported indices from the four psychosocial domains, whereas in C, only adult height and two indices (viz., total self-concept and school functioning), were correlated. The observed modest gains in psychosocial functioning for patients with TS treated with GH highlight the need for alternative approaches to assist them in coping with the challenges of their condition.

Abstract
BACKGROUND One of the most important vulnerabilities falling the efficacy of recombinant human growth hormone (r-hGH) treatment is low adherence especially in young patients. This study was planned to describe the correlation between r-hGH treatment efficacy and adherence in real-life setting using easypod™. METHODS Forty patients younger than 18 years, affected by a clinical condition in which r-hGH is available and treated with r-hGH easypod™, were enrolled in a retrospective, observational, real-world data, monocentric trial. The study design provided the retrospective collection of records collected by a questionnaire proposed to the patients and their parents and compared with registered data by the new generation electronic device r-hGH easypod™. Number of injections and doses were collected and used to assess the percentage of administered GH doses to measure treatment adherence. The r-hGH treatment efficacy was evaluated comparing standard deviation score for height (SDS) between baseline and follow-up visit, according to clinical practice. RESULTS The mean treatment adherence was 92.20% and it was inversely related to patients' age (R = - 0.358, p = 0.023), and significantly higher in the sub-group of patients with age between 10 and 13 years. Treatment adherence showed an inverse correlation with the years of therapy (R = - 0.453, p = 0.003) and with the number of r-hGH administrations (R = - 0.392, p = 0.012). However, the height increase did not reach a significant correlation with treatment adherence (R = - 0.067, p = 0.683). CONCLUSIONS Children and adolescent patients with GH deficiency due to different clinical conditions show high adherence to r-hGH treatment tested by easypod™. Easypod™ could be used as an important device to control patients' adherence in daily treatment for chronic diseases with expensive drugs.

Abstract
BACKGROUND Country-specific data on outcomes of treatment with recombinant human growth hormone are lacking. We present such data for children treated with growth hormone in Canada. METHODS We describe characteristics and outcomes of 850 children (mean age at baseline 8.5 yr) treated with growth hormone constituting the Canadian cohort of the multinational phase IV prospective observational Genetics and Neuroendocrinology of Short-stature International Study (GeNeSIS). The diagnosis associated with short stature was as determined by the investigator. Auxological data were evaluated yearly until near-adult height. Adverse events were assessed in all growth-hormone-treated patients. RESULTS The diagnosis ascribed as the cause of short stature was growth hormone deficiency in 526 children (61.9%), predominantly organic rather than idiopathic, particularly congenital pituitary abnormalities and intracranial tumours. All diagnostic groups with sufficient patients for analysis had increased height velocity standard deviation score (SDS) and height SDS during growth hormone treatment. For patients who reached near-adult height (n = 293), the mean height SDS was within the normal range for about 80% of patients with organic growth hormone deficiency (n = 131) or idiopathic growth hormone deficiency (n = 50), 50% of patients with idiopathic short stature (n = 10) and 46% of patients with Turner syndrome (n = 79). Eleven deaths were reported, 7 in patients with organic growth hormone deficiency. Serious adverse events considered related to growth hormone treatment (n = 19) were isolated except for medulloblastoma recurrence (n = 2) and adenoidal hypertrophy (n = 2). INTERPRETATION Growth hormone treatment was effective and had a good safety profile in Canadian children. Growth hormone dosages were lower than in the US and global GeNeSIS cohorts, and a greater proportion of treated Canadian children had organic growth hormone deficiency.

Abstract
OBJECTIVES Preliminary data from the French cohort of the Safety and Appropriateness of Growth hormone treatments in Europe (SAGhE) study raised concerns regarding the safety of recombinant human GH, suggesting that GH may increase mortality and incidence of stroke in patients treated during childhood for GH deficiency or short stature. We evaluated published safety data, focusing on mortality, neoplasms, cerebrovascular events and diabetes across a number of large-scale pharmaceutical company GH registries. DESIGN A literature review was conducted using PubMed, EMBASE and Google Scholar to identify all relevant safety data from manufacturers' GH registries published between 1988 and April 2016. Results were hand-sorted to exclude nonrelevant publications; bibliographic references from retrieved articles were evaluated for any additional references. RESULTS The published data do not support an increased risk of mortality in children or adults treated with GH. There was no evidence of an increased risk of stroke, new malignancy, leukaemia, nonleukaemic extracranial tumours or recurrence of intracranial malignancy in patients without risk factors. The risk of a second neoplasm is increased, particularly if patients have received radiation therapy for a central nervous system tumour. There may be an increased risk of type 2 diabetes in GH-treated patients, but this appears to be confined to those with pre-existing risk factors. CONCLUSIONS Patients with risk factors for malignancy or type 2 diabetes should be treated with caution and monitored during follow-up, but current published data provide reassurance on the long-term safety profile of GH in patients receiving GH treatment.

Abstract
PURPOSE Somatropin [recombinant growth hormone (rGH)] is approved in children and adults for several conditions involving growth disturbances and the corresponding biosimilar is available in Italy since 2006. No population-based data are available on the pattern of rGH use in Italian clinical practice. This study aimed at exploring the pattern of biosimilar and originator rGH use in six Italian centers, where different policy interventions promoted biosimilar use. METHODS This population-based, drug-utilization study was conducted in the years 2009-2014, using administrative databases of Umbria, Tuscany, and Lazio Regions and Local Health Units of Caserta, Treviso, and Palermo. Naïve rGH users were characterized, and prevalence of use and discontinuation were assessed over time. RESULTS Among 6,785 patients treated with rGH during the study years, 4,493 (66.2%) were naïve users (males/females = 1.3), mostly affected by GH deficiency. The prevalence of rGH use increased from 2009 to 2010, remaining stable thereafter, but it was heterogeneous across centers (twofold higher prevalence of use in center n.2 than centers n.4 and 1 in 2014). Biosimilar rGH uptake increased over time but was low (7.8% in 2014) and heterogeneous as well. Discontinuation of rGH therapy occurred in 54.0% of naïve users, more frequently in females than males (58.1 vs. 50.9%). During the first year of treatment, discontinuation was frequent (39.9%), but no statistically significant differences were observed in treatment persistence for biosimilar vs. originator rGH (p > 0.05). CONCLUSION Geographical heterogeneity in the prevalence of rGH use was observed. Similarly, the biosimilar rGH uptake was low and variable across centers. Post-marketing monitoring is required to continuously monitor the benefit-risk profile of rGH, thus guaranteeing greater savings than only promoting lowest cost rGH.

Abstract
CONTEXT Although pediatric growth hormone (GH) treatment is generally considered safe for approved indications, concerns have been raised regarding potential for increased risk of mortality in adults treated with GH during childhood. OBJECTIVE To assess mortality in children receiving GH. DESIGN Prospective, multinational, observational study. SETTING Eight hundred twenty-seven study sites in 30 countries. PATIENTS Children with growth disorders. INTERVENTIONS GH treatment during childhood. MAIN OUTCOME MEASURE Standardized mortality ratios (SMRs) and 95% confidence intervals (CIs) using age- and sex-specific rates from the general population. RESULTS Among 9504 GH-treated patients followed for ≥4 years (67,163 person-years of follow-up), 42 deaths were reported (SMR, 0.77; 95% CI, 0.56 to 1.05). SMR was significantly elevated in patients with history of malignant neoplasia (6.97; 95% CI, 3.81 to 11.69) and borderline elevated for those with other serious non-GH-deficient conditions (2.47; 95% CI, 0.99-5.09). SMRs were not elevated for children with history of benign neoplasia (1.44; 95% CI, 0.17 to 5.20), idiopathic GHD (0.11; 95% CI, 0.02 to 0.33), idiopathic short stature (0.20; 95% CI, 0.01 to 1.10), short stature associated with small for gestational age (SGA) birth (0.66; 95% CI, 0.08 to 2.37), Turner syndrome (0.51; 95% CI, 0.06 to 1.83), or short stature homeobox-containing (SHOX) gene deficiency (0.83; 95% CI, 0.02 to 4.65). CONCLUSIONS No significant increases in mortality were observed for GH-treated children with idiopathic GHD, idiopathic short stature, born SGA, Turner syndrome, SHOX deficiency, or history of benign neoplasia. Mortality was elevated for children with prior malignancy and those with underlying serious non-GH-deficient medical conditions.

Patients' perceptions on the usability of the SurePal™ self-injection device for Omnitrope ®: a questionnaire-based observational study conducted in paediatric patients in France. Ther Adv Endocrinol Metab 2017; 8:129-137. [PMID: 29051812 PMCID: PMC5638162 DOI: 10.1177/2042018817730545] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2017] [Accepted: 08/07/2017] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND A questionnaire-based survey was conducted to evaluate attitudes towards a reusable self-injection system, SurePal™, among paediatric patients with growth disturbances who were prescribed treatment with somatropin (Omnitrope®) as part of routine clinical practice. METHODS This cross-sectional survey was incorporated into the multinational, multi-centre, noninterventional PAtients TReated with Omnitrope® (PATRO) Children study. Questions were mainly focused on five areas: the attractiveness of SurePal™; training received; use of the device; opinion of the low-drug wastage system; experience compared with previous devices used (among pretreated patients). RESULTS Final results from participants in France are reported. Completed questionnaires were returned by 409 participants. Most patients (55%) were male and 89% were recombinant human growth hormone (rhGH)-treatment naïve. Around 57% of children completed the questionnaire by themselves, while 43% had help from a family member/other person. The mean (standard deviation) age of all participants was 11.3 (3.6) years, and most patients were aged 10-12 years (n = 126) or 13-15 years (n = 117). Overall, 86% of patients reported that preparing SurePal™ for injection was easy/very easy. Similarly, 83% reported that performing injections with SurePal™ was easy/very easy. The attractiveness of SurePal™ was rated as good/excellent by the majority (85%) of patients; this proportion was similarly high (> 80%) across all age groups. The dose-memory function was rated as helpful/very helpful by 54% of patients. Of the 174 patients who reported using the low drug-waste feature, 90% found it to be helpful/very helpful. Among the 24 pretreated patients, 17 reported that SurePal™ was better/much better than their previous device. CONCLUSIONS This questionnaire-based survey conducted in a large cohort of paediatric patients with growth disturbances from France confirms the ease of use of SurePal™ to support daily administration of Omnitrope® across all age groups. The demonstrated acceptability of the device may help to improve patient adherence to long-term daily treatment with rhGH.

Abstract
Early detection of abnormal growth, identification of the underlying cause, and appropriate treatment of the medical condition is an important issue for children with short stature. Growth hormone (GH) therapy is widely used in GH-deficient children and also in non-GH-deficient short stature cases who have findings conforming to certain indications. Efficacy of GH therapy has been shown in a multitude of short- and long-term studies. Age at onset of GH therapy is the most important factor for a successful treatment outcome. Optimal dosing is also essential. The aim of this review was to focus on challenges in the early diagnosis and appropriate management of short stature due to GH deficiency (GHD) and Turner syndrome. These are the most frequent two indications for GH therapy in Turkey approved by the Ministry of Health for coverage by the national insurance system.

Abstract
Background A questionnaire-based survey was conducted to assess attitudes toward a reusable self-injection system (SurePal™) among pediatric patients with growth disturbances who were prescribed treatment with Omnitrope® within routine clinical practice. Methods This was a multicenter, observational study, incorporated into the noninterventional PAtients TReated with Omnitrope® (PATRO) Children study. Included subjects, or their caregivers, completed a questionnaire on the following five main areas: attractiveness of SurePal™, training received, using the device, the low drug wastage system, and experience versus other devices used previously (pretreated patients). Responses were based on a 5-point scale, with 2 being the best possible outcome and −2 the worst possible outcome. Results In total, 550 patients were included in this study (338 from France, 169 from Germany, and 43 from the UK). The mean age ± standard deviation of participants was 10.8±3.5 years; the majority (57%) were male and growth hormone treatment naïve (88%). Almost half (49.8%) of children prepared their SurePal™ for injection themselves and 45.5% performed injections themselves. As patients progressed into their teens, the majority (≥75%) favored preparing SurePal™ and performing injections themselves, rather than seeking assistance. The attractiveness of SurePal™ was rated as excellent/good by 84.7% of patients overall; this rating was similarly high (≥79%) across countries and age-groups. Preparing (88.8%) and using (83.3%) SurePal™ were rated as very easy/easy by most patients; these ratings were similarly high, irrespective of country or age-group. The dose-memory function was rated as very helpful/helpful by 66.2% of patients. Among 246 patients who reported using the low drug-waste feature, 87.4% found it helpful. Among pretreated patients (n=64), 78.2% reported that SurePal™ was much better/better than their previous device. Conclusion These data confirm the ease of use and patient preference for SurePal™ among pediatric patients with growth disturbances.

Abstract
BACKGROUND Treatment outcome depends largely on treatment adherence (TA). However, studies analyzing TA in chronic endocrine diseases are scarce and controversial in childhood. PATIENTS AND METHODS We studied TA in 103 children treated subcutaneously with growth hormone (GH) and 97 children treated orally with thyroxin. TA was calculated based on the prescription refill rates. The number of GH injections was recorded by an autoinjector device in 23 children treated with GH. RESULTS The correlation between recorded TA and calculated TA based on prescription refill rates was very good (p < 0.001, r = 0.83). TA was lower (p < 0.01) in pubertal children compared to prepubertal children and in children self-administering their medication compared to those whose drug was administered by their parents, both in GH- and thyroxin-treated children. Overall, 67% of the pubertal children treated with GH and 58% of the pubertal children treated with thyroxin missed at least 1 dose per week. TA was higher (p < 0.001) in children with thyroxin treatment compared to children treated with recombinant human GH (8 vs. 26% missed >3 doses/week). DISCUSSION Puberty and self-administration of drugs were negative predictors of TA. Therefore, in puberty, prevention and treatment efforts should be undertaken to improve TA, especially when adolescents administer their drugs themselves.

Abstract
PURPOSE We examined auxological changes in growth hormone (GH)-treated children in Italy using data from the Italian cohort of the multinational observational Genetics and Neuroendocrinology of Short Stature International Study (GeNeSIS) of pediatric patients requiring GH treatment. METHODS We studied 711 children (median baseline age 9.6 years). Diagnosis associated with short stature was as determined by the investigator. Height standard deviation score (SDS) was evaluated yearly until final or near-final height (n = 78). Adverse events were assessed in all GH-treated patients. RESULTS The diagnosis resulting in GH treatment was GH deficiency (GHD) in 85.5 % of patients, followed by Turner syndrome (TS 6.6 %). Median starting GH dose was higher in patients with TS (0.30 mg/kg/week) than patients with GHD (0.23 mg/kg/week). Median (interquartile range) GH treatment duration was 2.6 (0.6-3.7) years. Mean (95 % confidence interval) final height SDS gain was 2.00 (1.27-2.73) for patients with organic GHD (n = 18) and 1.19 (0.97-1.40) for patients with idiopathic GHD (n = 41), but lower for patients with TS, 0.37 (-0.03 to 0.77, n = 13). Final height SDS was >-2 for 94 % of organic GHD, 88 % of idiopathic GHD and 62 % of TS patients. Mean age at GH start was lower for organic GHD patients, and treatment duration was longer than for other groups, resulting in greater mean final height gain. GH-related adverse events occurred mainly in patients diagnosed with idiopathic GHD.

Liu Z, Mohan S, Yakar S. Does the GH/IGF-1 axis contribute to skeletal sexual dimorphism? Evidence from mouse studies. Growth Horm IGF Res 2016; 27:7-17. [PMID: 26843472 PMCID: PMC5488285 DOI: 10.1016/j.ghir.2015.12.004] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2015] [Revised: 11/24/2015] [Accepted: 12/03/2015] [Indexed: 11/22/2022]
Abstract
The contribution of the gonadotropic axis to skeletal sexual dimorphism (SSD) was clarified in recent years. Studies with animal models of estrogen receptor (ER) or androgen receptor (AR) null mice, as well as mice with bone cell-specific ablation of ER or AR, revealed that both hormones play major roles in skeletal acquisition, and that estrogen regulates skeletal accrual in both sexes. The growth hormone (GH) and its downstream effector, the insulin-like growth factor-1 (IGF-1) are also major determinants of peak bone mass during puberty and young adulthood, and play important roles in maintaining bone integrity during aging. A few studies in both humans and animal models suggest that in addition to the differences in sex steroid actions on bone, sex-specific effects of GH and IGF-1 play essential roles in SSD. However, the contributions of the somatotropic (GH/IGF-1) axis to SSD are controversial and data is difficult to interpret. GH/IGF-1 are pleotropic hormones that act in an endocrine and autocrine/paracrine fashion on multiple tissues, affecting body composition as well as metabolism. Thus, understanding the contribution of the somatotropic axis to SSD requires the use of mouse models that will differentiate between these two modes of action. Elucidation of the relative contribution of GH/IGF-1 axis to SSD is significant because GH is approved for the treatment of normal children with short stature and children with congenital growth disorders. Thus, if the GH/IGF-1 axis determines SSD, treatment with GH may be tailored according to sex. In the following review, we give an overview of the roles of sex steroids in determining SSD and how they may interact with the GH/IGF-1 axis in bone. We summarize several mouse models with impaired somatotropic axis and speculate on the possible contribution of that axis to SSD.

Ital J Pediatr 2015; 41:71. [PMID: 26444854 PMCID: PMC4595189 DOI: 10.1186/s13052-015-0183-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2015] [Accepted: 10/01/2015] [Indexed: 11/17/2022] Open
Abstract
Background Noonan syndrome (NS) is an autosomal dominant disorder characterized by specific features including short stature, distinctive facial dysmorphic features, congenital heart defects, hypertrophic cardiomyopathy, skeletal anomalies and webbing of the neck. Molecular screening has shown that the majority of individuals with NS have a mutation in the PTPN11 gene. Noonan syndrome children may show an impaired growth hormone (GH)/insulin-like growth factor axis. Moreover, recombinant human GH (rhGH) has been shown to improve growth rate in patients with NS, although data are still limited. Methods In the present study, we assessed growth response following GH therapy (0.25 mg/Kg/week) in 5 (2 M and 3 F) GH-deficient NS patients (NSGHD, mean age 8.5 years) and in 5 (2 M and 3 F) idiopathic GH deficient (IGHD, mean age 8.6 years) patients. We also evaluated the safety of rhGH therapy in NS patients with GHD. Results At the beginning of GH treatment, height and growth rate were statistically lower in NSGHD children than in IGHD ones. During the first three years of rhGH therapy, NSGHD patients showed a slight improvement in height (from −2.71 SDS to −2.44 SDS) and growth rate (from −2.42 SDS to −0.23 SDS), although the values were always significantly lower than in IGHD children. After five years of rhGH treatment, height gain was higher in IGHD children (mean 28.3 cm) than in NSGHD patients (mean 23.6 cm). During the first five years of rhGH therapy, regular cardiological and haematological check-ups were performed, leading to the conclusion that rhGH therapy was safe. Conclusions In conclusion, pre-pubertal NS children with GHD slightly increased their height and growth rate during the first years of GH therapy, although the response to rhGH treatment was significantly lower than IGHD children. Furthermore, the therapy appeared to be safe since no severe adverse effects were reported, at least during the first five years. However, a close follow-up of these patients is mandatory, especially to monitor cardiac function.

Abstract
Background SurePal™ is a reusable self-injection system that has been developed to support daily administration of Omnitrope® (Sandoz, Kundl, Austria). A questionnaire-based cross-sectional survey was conducted to evaluate acceptability of, and preference for, SurePal™ in pediatric patients who were prescribed treatment with Omnitrope® within routine clinical care. Methods This multicenter, observational study was incorporated into the ongoing non-interventional PATRO (PAtients TReated with Omnitrope®) Children study. Patients (or caregivers) were provided with a questionnaire that included five main topics; attractiveness of the device, training received, using SurePal™, the low drug wastage system, and experience versus other devices used previously (where applicable). Questions were scored on a 5-point scale, with −2 being the worst possible outcome (eg, very hard/very poor) and 2 being the best possible outcome (eg, very easy/excellent). Results A total of 186 patients were included in this study (Germany, n=154; UK, n=32). The attractiveness of SurePal™ was rated as excellent/good by 87.1% of patients. Overall, 86.5% of patients found that using their SurePal™ was very easy/easy. Almost all patients (96.2%) found that preparing their SurePal™ for injection was very easy/easy, and 89.2% found that injecting with SurePal™ was very easy/easy. 85.5% of patients recorded that the dose memory function was helpful, and 87.6% that taking their SurePal™ apart after an injection was very easy/easy. Of the 88 patients who recorded that they had used the low drug waste feature, 89.8% found the feature to be helpful. Among pre-treated patients (n=42), 81% recorded that SurePal™ was much better/better than their previously used device. Conclusion This questionnaire-based cross-sectional survey in pediatric patients confirms the ease of use and patient preference for SurePal™, a reusable self-injection system that has been developed to support daily administration of Omnitrope®.

Abstract
INTRODUCTION Country-specific information on pediatric GH therapy is available from multi-national studies. METHODS A total of 1294 children in Spain enrolled in the observational Genetics and Neuroendocrinology of Short-stature International Study (GeNeSIS). Adverse events were assessed in all GH-treated patients (n=1267) and effectiveness in those with GH deficiency (GHD, 78%). RESULTS Mean age at time of entry to the study was 9.8 years. GH was initiated at a median (Q1-Q3) 0.22 (0.20-0.25) mg/kg/week and administered for 2.8 (1.6-4.4) years. For 262 patients with GHD and 4-year data, mean (95% CI) height velocity was 4.3 (4.1 - 4.6) cm/year at baseline, 9.0 (8.7 to 9.4) cm/year at 1-year, and 5.5 (5.2 to 5.8) cm/year at 4-years. Height standard deviation score (SDS) was -2.48 (-2.58 to -2.38) at baseline and -1.18 (-1.28 to -1.08) at 4 years. Final height SDS minus target height SDS (n=241) was -0.09 (-0.20 to 0.02). In 1143 GH-treated patients with ≥1 year follow-up, 93 (8.1%) reported treatment-emergent adverse events. Serious events were reported for 7 children, with 2 considered GH-related. CONCLUSION These data confirm the benefit of GH replacement therapy on height gain for the patients in Spain. The safety profile was consistent with that already known for GH therapy.

Abstract
Girls and women with Turner's syndrome who come to medical attention older than 12 years present a challenge of medical management. Puberty is already delayed and some compromises have to be made in adjusting the timing of artificially induced puberty to optimise overall outcome with respect to stature, secondary sex characteristics, and psychosocial endpoints. Additionally, individuals who present with primary amenorrhoea to adult services might miss the opportunity for effective growth hormone treatment. Further, induction of puberty regimens lack an evidence base or even clear guidelines for the timing and dose of oestrogen replacement. We have searched the scientific literature to inform management of Turner's syndrome.

Abstract
BACKGROUND/AIMS Treatment of children with growth disorders with recombinant human growth hormone is necessary for improved outcomes, including final height. METHODS Adherence data from the Observational Study Saizen®-online, recorded with the easypod™ device collected between October 2009 and May 2011, were analyzed in pediatric patients receiving recombinant human growth hormone treatment for a variety of growth disorders. RESULTS Data from 75 children (46 boys, 29 girls) with different growth disorders were analyzed over a period of 343 ± 201 (SD) days. Boys and girls showed similar mean ± SD adherence rates of 90.5 ± 3.1% and 92.2 ± 10.7%, respectively. Pubertal children (n = 41) had a significantly lower adherence rate (89.1 ± 13.7%) than prepubertal children (n = 29) (96.5 ± 3.9%; p < 0.005). There were nonsignificant differences in adherence rates according to diagnosis: growth hormone deficiency (n = 48) 91.4 ± 11.0%, small for gestational age (n = 18) 91.1 ± 15.3%, Turner syndrome (n = 6) 86.0 ± 14.5%, and chronic renal failure (n = 3) 99.3 ± 1.0%, although the latter two groups were small. CONCLUSION Our data indicate that only a small number of pediatric patients using the easypod device had poor adherence to treatment. Further reliable adherence data are required to identify factors affecting long-term adherence in this population.

Abstract
OBJECTIVE To assess the user-friendliness of the Norditropin FlexPro (Novo Nordisk A/S, Bagsvaerd, Denmark), a newly developed growth hormone (GH) injection pen. METHODS This study consisted of a single-center, single-arm, open-label, questionnaire based survey of patients undergoing GH treatment for diverse indications who were scheduled to switch from the formerly used device Norditropin NordiFlex (Novo Nordisk A/S) to the FlexPro and evaluate each device's usability. RESULTS A total of 82 patients participated in the study. Compared to the NordiFlex, the FlexPro was regarded as easier to grip, easier to hold during injection, and more stable during injection. The degree of pain at insertion perceived by the patient and the patient's fear of injection were significantly decreased when using the FlexPro, and 81% of the respondents selected the FlexPro as the more preferable device. CONCLUSIONS The FlexPro was more user-friendly than the NordiFlex. Perception of pain at insertion and fear of injection were lessened by using the FlexPro.

Abstract
This study analyzes the body anthropometric measurements in females with Turner syndrome (TS) not treated with recombinant human growth hormone. Height, weight, head circumference, and body mass index (BMI) data were collected from 93 patients. Their ages ranged from 6 months to 24 years (mean 10 ± 4.3 years). Chromosomal analysis revealed: 55 patients with 45,X and 38 patients with mosaic karyotypes. Patients were divided into yearly age groups. Standard growth curves were constructed for these Egyptian Turner syndrome (TS) patients. Mean and standard deviations were estimated across the age groups. When comparing the mean heights of patients to the Egyptian standards, short stature (≤2 SD) was found in 96.8% of patients older than 6 years. Patients' mean weight and BMI were higher than controls. The mean height of the studied Egyptian patients was slightly lower than that of females with TS in UK and European patients. Therefore, local reference values are more appropriate than International standards. The charts presented here can be used to optimize routine healthcare for Egyptian TS patients. The use of growth charts specific for Egyptian TS patients can help to discover early physical developmental delay and suggests the necessity of looking for concomitant diseases affecting growth.
