The influence of genotype makeup on the effectiveness of growth hormone therapy in children with Prader-Willi syndrome.

BACKGROUND: Prader-Willi syndrome (PWS) is a rare multisystemic hereditary illness. Recombinant human growth hormone (rhGH) therapy is widely recognized as the primary treatment for PWS. This study aimed to examine how different PWS genotypes influence the outcome of rhGH treatment in children with PWS. METHODS: A review was conducted on 146 Chinese children with PWS, genetically classified and monitored from 2017 to 2022. Unaltered and modified generalized estimating equations (GEE) were employed to examine the long-term patterns in primary outcomes (growth metrics) and secondary outcomes (glucose metabolism metrics and insulin-like growth factor-1 (IGF-1)) during rhGH therapy. The study also evaluated the prevalence of hypothyroidism, hip dysplasia, and scoliosis before and after rhGH treatment. RESULTS: Children with PWS experienced an increase in height/length standard deviation scores (SDS) following rhGH administration. The impact of rhGH therapy on growth measurements was similar in both the deletion and maternal uniparental diploidy (mUPD) cohorts. Nevertheless, the deletion group was more prone to insulin resistance (IR) compared to the mUPD group. No significant variations in growth metrics were noted between the two groups (P > 0.05). At year 2.25, the mUPD group showed a reduction in fasting insulin (FINS) levels of 2.14 uIU/ml (95% CI, -4.26, -0.02; P = 0.048) and a decrease in homeostasis model assessment of insulin resistance (HOMA-IR) of 0.85 (95% CI, -1.52, -0.17; P = 0.014) compared to the deletion group. Furthermore, there was a decrease in the IGF standard deviation scores (SDS) by 2.84 (95% CI, -4.84, -0.84; P = 0.005) in the mUPD group during the second year. The frequency of hip dysplasia was higher in the mUPD group compared to the deletion group (P < 0.05). CONCLUSIONS: rhGH treatment effectively increased height/length SDS in children with PWS, with similar effects observed in both deletion and mUPD genotypes. Children with mUPD genetype receiving rhGH treatment may experience enhanced therapeutic effects in managing PWS.

Case report: Epilepsy during the use of recombinant human growth hormone: a report on two cases and a literature review.

Background: Epilepsy during recombinant human growth hormone (rhGH) therapy is rare in children. The potential association between rhGH treatment and epilepsy remains unclear. Methods: We retrospectively analyzed the clinical data of two Chinese boys who experienced epilepsy during the use of rhGH and reviewed the relevant literature. Results: Case 1, an 8-year and 2-month-old boy, was diagnosed with short stature, malnutrition, and congenital hypothyroidism. He was on levothyroxine sodium tablets for a long time. Recurrent febrile convulsions were present at 6-7 years. Electroencephalogram and magnetic resonance imaging (MRI) showed no abnormality, and no treatment was given. He was diagnosed with complex febrile convulsions. The boy started rhGH treatment (approximately 0.15 IU/kg/day, sc, qd) at 8 years and 4 months. Epilepsy occurred three times during the 6 months of rhGH treatment. Electroencephalography confirmed a definitive diagnosis of epilepsy. Then, he discontinued rhGH treatment at 8 years and 11 months and started taking levetiracetam (0.25 g, po, bid) for antiepileptic therapy. Epilepsy was well-controlled 4 months later. He continued rhGH treatment at 10 years and 3 months and has been on rhGH treatment until now, with no recurrence of epilepsy. He has been taking levetiracetam to date. Case 2, a 9-year and 1-month-old boy, was diagnosed with central precocious puberty, predicted short final height, and overweight. He started treatment with triptorelin (3.75 mg, im, q4w) and rhGH (approximately 0.15 IU/kg/day, sc, qd) at 9 years and 3 months. He tended to fall repeatedly when he was approximately 10 years old. Electroencephalography showed a few medium- to high-amplitude sharp waves and sporadic sharp slow waves in the left middle temporal region, sometimes involving the left posterior temporal region. He was diagnosed with epilepsy. Triptorelin discontinuance provided no symptom relief, which worsened further. Subsequently, he withdrew from rhGH treatment, and the symptoms occurred occasionally within a week and stopped after 15 days. The electroencephalogram returned to normal. No further seizures occurred during follow-up to date. Conclusion: During the use of rhGH in short-stature children with complex febrile convulsions or underlying lesions related to neurological impairment or those being treated with antiepileptic drugs, epilepsy may be induced.

Effect of long-acting PEGylated growth hormone for catch-up growth in children with idiopathic short stature: a 2-year real-world retrospective cohort study.

Several evidence gaps exist regarding the use of long-acting polyethylene glycol recombinant human growth hormone (PEG-rhGH) in children with idiopathic short stature (ISS), particularly studies conducted in real-world settings, with long-term follow-up, involving varied dosing regimens, and in comparison with daily rhGH. The study aimed to evaluate the effectiveness, safety, and adherence of once-weekly PEG-rhGH for catch-up growth in children with prepubertal ISS compared to daily rhGH. A real-world retrospective cohort study was conducted in prepubertal children with ISS in China. Children who voluntarily received once-weekly PEG-rhGH or daily rhGH were included and were followed up for 2 years. Ninety-five children were included, 47 received PEG-rhGH 0.2-0.3 mg/kg weekly and 48 received daily rhGH. Outcome measures included effectiveness in catch-up growth, adverse events, and treatment adherence. Height velocity increased significantly in both groups during rhGH therapy. In children who received PEG-rhGH treatment, height velocity was 10.59 ± 1.37 cm/year and 8.75 ± 0.86 cm/year in the first and second year, respectively, which were significantly more than those who received daily rhGH (9.80 ± 1.05 cm/year, P = 0.002, and 8.03 ± 0.89 cm/year, P < 0.001). The height standard deviation score improved at the end of the second year for all children (P < 0.001). However, children who received PEG-rhGH showed more excellent improvement than those with daily rhGH (1.65 ± 0.38 vs. 1.50 ± 0.36, P = 0.001). In children who received PEG-rhGH, lower missed doses were observed than those with daily rhGH (0.75 ± 1.06 vs. 4.4 ± 2.0, P < 0.001). No serious adverse events were observed. CONCLUSION: PEG-rhGH demonstrated superior effectiveness and adherence compared to daily rhGH in the treatment of children with ISS. The safety profiles were similar between the two treatments. WHAT IS KNOWN: • Recombinant human growth hormone (rhGH) has been used to increase adult height in children with idiopathic short stature (ISS), and its safety profile is comparable to other indications for growth hormone treatment. • The use of long-acting rhGH in children with ISS is still an area of uncertainty. WHAT IS NEW: • This 2-year real-world study provides new evidence that PEGylated rhGH (PEG-rhGH) is more effective than daily rhGH in promoting catch-up growth in children with ISS. • PEG-rhGH also demonstrated superior treatment adherence compared to daily rhGH in children with ISS. • The safety profiles of PEG-rhGH and daily rhGH were found to be similar.

Long-term efficacy and safety of PEGylated recombinant human growth hormone in treating Chinese children with growth hormone deficiency: a 5-year retrospective study.

OBJECTIVES: The study endeavored to evaluate the prolonged efficacy and safety of PEGylated rhGH (PEG-rhGH) administration in Chinese children diagnosed with growth hormone deficiency (GHD) over a 5-year period. METHODS: A retrospective analysis was conducted on children with GHD, who received a 0.2 mg/kg/week dose of PEG-rhGH between 2016 and 2023 in our department. RESULTS: The height standard deviation score (Ht SDS) exhibited a marked elevation post-PEG-rhGH administration (p<0.001), sustaining this enhancement beyond year 3, with increments recorded at 0.94±0.37, 1.49±0.48, 1.77±0.51, 2.12±0.65, and 2.15±0.58 across 5 years. Similarly, the height velocity (HV), insulin-like growth factor-1 standard deviation score (IGF-1 SDS), and bone age to chronological age ratio (BA/CA ratio) underwent significant augmentations (p<0.01). Remarkably, no signs of rapid bone maturation were detected during the 5-year observation. Among the participants, 31 patients (59.62 %) experienced adverse events, of which eight instances (15.38 %) were classified as treatment-related adverse events, but none were severe or unexpected. Additionally, high-density lipoprotein (HDL) levels rose while low-density lipoprotein (LDL) levels fell, both remaining within the standard range throughout the treatment phase. CONCLUSIONS: Administering PEG-rhGH at a dosage of 0.2 mg/kg/week proved both effective and well-tolerated in treating prepubertal children with GHD. This regimen also demonstrated positive impacts on lipid metabolism over an extended treatment period.

Preferences for Injection Device Settings and the Association with Adherence to Growth Hormone Treatment in Patient with Growth Disorders.

Adherence to recombinant human growth hormone (r-hGH; somatropin, [Saizen®], Merck Healthcare KGaA, Darmstadt, Germany) treatment is important to achieve positive growth and other outcomes in children with growth disorders. Automated injection devices can facilitate the delivery of r-hGH, injections of which are required daily for a number of years. The ability to adjust injection device settings may improve patient comfort and needle anxiety, influencing adoption and acceptance of such devices, thereby improving treatment adherence. Here, we present the results of a retrospective observational study which investigated the association between injection device settings and adherence in the first 3 months of treatment in patients with growth disorders. Patients aged ≥2 and <18.75 years of age at treatment start, with ≥3 months of adherence data from start of treatment with the third generation of the easypod® device (EP3; Merck Healthcare KGaA, Darmstadt, Germany) were selected (N=832). The two most chosen combinations of device settings at treatment start were the default settings for injection speed, depth and time, or a slow injection speed and default depth and time. These combinations also demonstrated the highest adherence rates (94% and 95%, respectively) compared to other device settings (89%). A higher proportion of patients with intermediate/low adherence in the first month of treatment (31%, n=18/59) changed the device settings during treatment compared with those with high adherence (16%, n=128/803) (p=0.005). The ability to adjust injection device settings offers a valuable opportunity for personalizing treatment, improving patient comfort and treatment adherence.

Long-acting growth hormone in the management of GHD in France.

Approximately 10,000 children in France with growth hormone deficiency (GHD) are being administered daily recombinant human growth hormone (rhGH). Although this treatment has long proved efficient for restoring children's growth and metabolism, daily injections of rhGH have a few limitations, such as difficulties in terms of adherence to treatment, which may compromise growth during childhood but also metabolism in adulthood. In addition to the disease burden and besides the adherence hurdles, the obligations related to daily injection have a negative impact on the quality of life of patients and their families. The hypothesis that injections administered at intervals of 1 week, or even 1 month, could improve compliance, reduce treatment discontinuations, and optimize quality of life and therapeutic effectiveness has led to the emergence of new long-acting growth hormone (LAGH). Recent access to LAGHs (somatrogon MA) on the European and French market will likely be followed by a high demand from the families concerned and may raise questions on their effectiveness, safety, and practical use. Numerous practical and practice-related points are needed to guide prescribing physicians while many concerns are still left unresolved (treatment effectiveness or ineffectiveness endpoints, long-term effectiveness, etc.). These issues can only be addressed in the future by compiling registries and conducting long-term real-world studies.

Case Report: Two different acromelic dysplasia phenotypes in a Chinese family caused by a missense mutation in FBN1 and a literature review.

Background: Acromelic dysplasia caused by FBN1 mutation includes acromicric dysplasia (AD), geleophysic dysplasia 2 (GD2), and Weill-Marchesani syndrome 2 (WMS2). All three diseases share severe short stature and brachydactyly. Besides phenotypic similarity, there is a molecular genetic overlap among them, as identical FBN1 gene mutations have been identified in patients with AD, GD2, and WMS2. However, no family with different acromelic dysplasia phenotypes due to the same variant has been described in English reports. Case report: The proband presented with typical facial features, severe short stature, short limbs, stubby hands and feet and radiological abnormalities. Her elder sister and mother had similar physical features. In addition, her elder sister was found to have aortic valve stenosis by echocardiography. Mutation analysis demonstrated a heterozygous missense mutation, c.5179C>T (p.Arg1727Trp) in exon 42 of the FBN1. The proband and her mother were diagnosed with AD, and her elder sister with GD2. The proband was treated with recombinant human growth hormone (rhGH) and had a body length gain of 0.72 SDS in half a year. Conclusion: These findings expand the phenotypic spectrum of FBN1 gene mutations and highlight that identical FBN1 genotypes can result in different phenotypes of acromelic dysplasia in a family. The efficacy of rhGH therapy in patients with acromelic dysplasia is controversial. More follow-up is needed on the long-term efficacy of rhGH therapy.

Healthcare professionals' perspectives towards the digitalisation of paediatric growth hormone therapies: expert panels in Italy and Korea.

Introduction: To analyse the perspectives of healthcare professionals (HCPs) regarding the acceptance of digital health solutions for growth hormone (GH) deficiency care. This study identified factors impacting HCPs' intent to use and recommend digital solutions supporting recombinant-human growth hormone (r-hGH) therapy in Italy and Korea with a use case of connected drug delivery system (Aluetta® with Smartdot™) integrated in a platform for GH treatment support (the Growzen™ digital health ecosystem). Methods: Participatory workshops were conducted in Rome, Italy, and Seoul, Korea, to collect the perspectives of 22 HCPs on various predefined topics. HCPs were divided into two teams, each moderated by a facilitator. The workshops progressed in five phases: introduction of the project and experts, capturing views on the current context of digitalisation, perceived usefulness and ease of use of Aluetta® with Smartdot™, exploration of the perception of health technology evolution, and combined team recommendations. Data shared by HCPs on technology acceptance were independently analysed using thematic analysis, and relevant findings were shared and validated with experts. Results: HCPs from both Italy and Korea perceived Aluetta® with Smartdot™ and the Growzen™ based digital health ecosystem as user-friendly, intuitive, and easy-to-use solutions. These solutions can result in increased adherence, a cost-effective healthcare system, and medication self-management. Although technology adoption and readiness may vary across countries, it was agreed that using digital solutions tailored to the needs of users may help in data-driven clinical decisions and strengthen HCP-patient relationships. Conclusion: HCPs' perspectives on the digitalisation in paediatric GH therapies suggested that digital solutions enable automatic, real-time injection data transmission to support adherence monitoring and evidence-based therapy, strengthen HCP-patient relationships, and empower patients throughout the GH treatment process.

Primary response in GHD children treatment as a predictor for long-term therapy effectiveness therapy effectiveness.

INTRODUCTION: Short stature in growth hormone deficiency (GHD) can be treated with recombinant human growth hormone (rhGH), which is proven to be both safe and effective. However, a considerable number of patients does not achieve satisfying therapy outcomes. AIM OF THE STUDY: To evaluate the predictive effect of height increase in the first year of rhGH treatment on long-term therapy outcomes. MATERIAL AND METHODS: 165 short-stature children (mean age 10.72 ±3.33 years; 63% males), diagnosed with GHD, treated with rhGH for at least one year (mean follow-up 4.32 ±1.80 years), divided into 2 groups according to the change in height standard deviation score (SDS) after the first year of rhGH treatment: good responders (GR) and poor responders (PR). Then, in one-year intervals, patient's chronological age, bone age, height, weight, insulin-like growth factor level, and rhGH dose were all assessed. RESULTS: In the GR group, mean height velocity SDS up to five years of observation was 1.19 ±0.41/year and in the PR group 0.59 ±0.38/year. The differences were statistically significant (p < 0.05). CONCLUSIONS: The primary response to the rhGH treatment in GHD children seems to be a good predictor for long-term therapy outcomes.

The growzen™ buddy smartphone app to improve adherence in patients receiving recombinant human growth hormone therapy: a retrospective observational study in Argentina.

Introduction: This study in Argentina evaluated the impact of the growzen™ buddy smartphone app on adherence to recombinant human growth hormone (r-hGH) treatment. Methods: The adherence data, invitation dates with a link to the app, app activation dates, and height measurements entered were extracted from the growzen™ digital health ecosystem. Patients with 12 months of adherence data, aged ≥2 years at treatment start, and aged <19 years were selected both before and after app implementation. Mean adherence was classified as optimal (≥85%) versus suboptimal (<85%). Adherence before and after implementation and the pre-post effect on adherence were assessed. Results: Data for 830 patients were available. Prior to app implementation, the proportion of patients with optimal adherence was 68% (n = 348/515). Following the app implementation, out of 315 patients, 302 (96%) received an invitation with a link to the app, 225 (71%) activated their account, and 127 (40%) entered height data in the first year. There was a significant early increase in the proportion of patients with optimal adherence following implementation: 82% (n = 258/315), p < 0.001. After implementation, the proportion of patients with optimal adherence included 80% (n = 78/98) of those with an active account who did not enter height measurements and 89% (n = 113/127) of those who did. There was a significant and positive pre-post app effect on adherence (p < 0.01) in patients with an active account. Discussion: Our results show that using the growzen™ buddy app has a rapid and positive impact on adherence to r-hGH treatment, and patients who were more engaged with the app demonstrated better adherence.

Clinical profiles and molecular genetic analyses of 98 Chinese children with short statures.

Background: Short stature is one of the most prevalent endocrine disorders in children, and its genetic basis is a complex and actively researched subject. Currently, there is limited genetic research on exome sequencing for short stature, and more large-scale studies are necessary for further exploration. Methods: The retrospective study entailed investigation of 98 Chinese children with short statures (height SDS ≤ -2.5) of unknown etiologies recruited between 2017 and 2021. Whole-exome sequencing (WES) was performed on these patients to identify the potential genetic etiologies. The clinical data were reviewed retrospectively to assess the pathogenicity of the identified mutations. Additionally, 31 patients consented to and received recombinant human growth hormone (rhGH) therapy for 12 months. The short-term effects of rhGH treatment were evaluated across different etiologies of patients with short statures. Results: The WES results were used to identify 31 different variants in 18 genes among 24 (24.5%) patients. Individuals with more severe short statures were more likely to have underlying genetic etiologies. Short stature accompanied by other phenotypes had significantly higher diagnostic yields than simple severe short stature. The rhGH therapy demonstrated efficacy in most children. Nevertheless, the treatment response was suboptimal in a boy diagnosed with 3M syndrome. Conclusion: WES is an important approach for confirming genetic disorders in patients with severe short statures of unknown etiologies, suggesting that it could be used as a primary diagnostic strategy. The administration of rhGH may not be suitable for all children with short statures, and the identification of the genetic cause of short stature by WES has significant guidance value for rhGH treatment.

A case report: Alport syndrome and growth hormone deficiency associated with a new COL4A4 mutation.

Background: Alport syndrome (AS) is a rare progressive hereditary kidney disease that is clinically principally associated with hematuria, proteinuria, and progressive renal dysfunction. This condition not only impairs renal function but also potentially affects auditory and ocular health, significantly impacting the patient's quality of life. Case Description: This article reports a young girl with AS, combined with dwarfism attributable to growth hormone (GH) deficiency, diagnosed at Wenzhou People's Hospital in 2019. The clinical data and diagnostic steps were retrospectively analyzed. Genetic testing showed that she carried a new mutation in the COL4A4 gene, c.2317_2318delAG (p.R773Gfs*14), classified as "pathogenic" under the criteria of the American College of Medical Genetics and Genomics (ACMG), confirming her AS diagnosis. Significantly, the patient's height was more than two standard deviations (SDs) below the average for children of her race, sex, and age. The peak GH level post-stimulation was below 5 ng/mL, coupled with a growth rate of less than 5 cm/year, leading to the diagnosis of GH deficiency. Consequently, recombinant human GH (rhGH) therapy was initiated. Conclusions: After a year of rhGH treatment, we observed a notable increase in her height, without any adverse effects like elevated intracranial pressure, hypothyroidism, or worsening kidney function.

Gonadal Failure in a Male With 3-M Syndrome.

OMIM 273750 (3-M) syndrome is a rare cause of severe short stature with variable dysmorphic features caused by pathogenic variants in several genes including cullin7 gene (CUL7). Hypogonadism and hypospadias have been described in only a few males. We report a patient with CUL7 pathogenic variant who had bifid scrotum and perineal hypospadias at birth. He entered puberty spontaneously at age 12 years and appropriately completed pubertal development by 15 years. Subsequently, a regression of testicular volumes, increased gonadotropin levels, and reduced (although normal) testosterone levels were observed. This case highlights the importance of careful pubertal monitoring as pubertal dysfunction may be associated with 3-M syndrome.

Optimal final adult height achieved by low-dose recombinant human growth hormone therapy.

Background: Thailand has been administering the recombinant human growth hormone (rhGH) treatment for >20 years. Due to limited resources being available, efforts have been directed toward utilizing rhGH at the lowest feasible dose. However, there is currently a lack of evidence in terms of the efficacy and outcomes. Objective: To evaluate the auxological outcomes of growth hormone (GH) treatment and the GH secretion ability after reaching final adult height (FAH) and discontinuing rhGH. Methods: Data of 40 patients were retrospectively reviewed. The clinical characteristics, auxological data, and results of biochemical and endocrine investigations before and during rhGH treatment were evaluated. In addition, GH retesting was performed in 24 patients using the insulin tolerance test. Results: Twenty patients (50%) had complete growth hormone deficiency (GHD), defined as peak stimulated GH level <5 ng/mL, and the remaining patients had partial GHD. Most patients were male (n = 25, 62.5%). The mean age at which rhGH was initiated was 8.9 years. Patients with partial GHD received a higher dose of rhGH than those with complete GHD (30.9 µg/kg/d vs. 26.2 µg/kg/d, P = 0.02). Patients with complete and partial GHD reached FAH at height standard deviation scores (SDSs) of -0.65 and -1.47, respectively. The factors associated with obtaining a good clinical response in terms of height gain included peak-stimulated GH level, age of puberty, and age of discontinuing rhGH. After completing the rhGH treatment, 13 of the 24 patients showed normal GH secretion. Patients with multiple pituitary hormone deficiency (MPHD) were likely to have persistent GHD through adulthood (n = 8, 88.9%). Conclusion: This study has demonstrated that the use of low-dose rhGH could result in healthy populations achieving optimal FAHs. Patients with MPHD might not require retesting as they were likely to have persistent GHD. The results obtained in this research highlight the benefits of the treatment. This treatment can be applied in resource-limited countries.

Are Young People with Turner Syndrome Who Have Undergone Treatment with Growth and Sex Hormones at Higher Risk of Metabolic Syndrome and Its Complications?

INTRODUCTION: Metabolic syndrome (MetS), characterized by visceral obesity, glucose abnormalities, hypertension and dyslipidemia, poses a significant risk of diabetes and cardiovascular disease. Turner syndrome (TS), resulting from X chromosome abnormalities, carries health complications. Despite growing evidence of an increased risk of MetS in women with TS, its prevalence and risk factors remain under investigation. These considerations are further complicated by the varying timing and dosages of treatment with growth hormone and sex hormones. METHODS: We conducted a cross-sectional study comparing 44 individuals with TS with 52 age-matched control subjects. Growth hormone treatment in the study group was administered for varying lengths of time, depending on clinical response. We collected anthropometric, metabolic, endocrine and body composition data. Statistical analyses included logistic regression. RESULTS: Baseline characteristics, including age, BMI and height, were comparable between the TS and control groups. Hormonally, individuals with TS showed lower levels of testosterone, DHEA-S, and cortisol, as well as elevated FSH. Lipid profiles indicated an atherogenic profile, and the body composition analysis showed increased visceral adipose tissue in those with TS. Other metabolic abnormalities were common in individuals with TS too, including hypertension and impaired fasting glucose levels. The risk of MetS components was assessed in subgroups according to karyotypes: monosomy 45X0 vs. other mosaic karyotypes. Logistic regression analysis showed a significant association between increased visceral adipose tissue in subjects with TS. Those with metabolic complications tended to have less muscle strength compared to those without these complications in both the study and control groups. CONCLUSIONS: This study highlights the unique metabolic and cardiovascular risk profile of individuals with TS, characterized by atherogenic lipids, higher levels of visceral adipose tissue and increased metabolic abnormalities. These findings underscore the importance of monitoring metabolic health in individuals with TS, regardless of age, BMI or karyotype, and suggest the potential benefits of lifestyle modification, building more muscle strength, and weight control strategies. Further research is needed to better understand and address the metabolic challenges faced by women with TS.

[Safety considerations for the clinical application of recombinant human growth hormone]. / é‡ç»„äººç”Ÿé•¿æ¿€ç´ ä¸´åºŠåº”ç”¨çš„å®‰å ¨æ€§æ€è€ƒ.

Recombinant human growth hormone (rhGH) is an effective therapeutic drug for improving short stature. Currently, rhGH can be used for various causes of short stature, including growth hormone deficiency, and the expansion of its clinical application has raised concerns about its safety. Based on existing evidence, when rhGH is used in a standardized manner for physiological replacement therapy, its safety profile is favorable. In clinical practice, attention should be focused on short-term safety during rhGH treatment, with the combination of literature evidence and clinical experience. There is still no definitive conclusion on the long-term safety due to insufficient duration of rhGH treatment. This paper reviews the possible adverse events that may occur during rhGH treatment and their risk control measures, aiming to help clinical physicians understand the overall safety of rhGH treatment and improve its clinical standardization.

[Management of transition growth hormone deficiency]. / è¿‡æ¸¡æœŸç”Ÿé•¿æ¿€ç´ ç¼ºä¹ç—‡çš„ç®¡ç†.

With an increasing understanding of growth hormone deficiency, there has been a growing emphasis on the management of transition growth hormone deficiency (TGHD) in clinical practice. The inadequate diagnosis and treatment of TGHD have been a major clinical concern, leading to the development of relevant guidelines and consensus internationally. This article summarizes the evaluation, diagnosis, treatment, and clinical challenges of TGHD based on these guidelines, consensus, and existing clinical studies, aiming to optimize and further improve the clinical diagnosis, treatment, and management of TGHD.

The efficacy of therapeutic interventions on paediatric burn patients' height, weight, body composition, and muscle strength: A systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of therapeutic interventions on pediatric burn patients' height, weight, body composition, and muscle strength. METHODS: A systematic literature search was conducted in PubMed, Embase, and Web of Science up to March 2021. Eligible interventional studies reported metrics on the height, weight, body composition, or muscle strength of pediatric burn patients in a peer-reviewed journal. Meta-analyses were performed if ≥ 2 trials of clinical homogeneity reported on an outcome measure at the same time point post-burn. RESULTS: Twenty-six interventional studies were identified, including twenty-two randomised controlled trials and four non-randomised trials. Most studies were conducted by a single institution. On average, the burn covered 45.3% ( ± 9.9) of the total body surface area. Three categories of interventions could be distinguished: rehabilitative exercise programs, pharmacologic agents, and nutrition support. CONCLUSIONS: Each of the interventions had a positive effect on height, weight, body composition, or muscle strength. The decision to initiate an intervention should be made on a case-by-case basis following careful consideration of the benefits and risks. In future research, it is important to evaluate the heterogeneity of intervention effects and whether participation in an intervention allowed pediatric burn patients to reach the physical and functional status of healthy peers.

[Pharmacological therapies for height improvement in pubertal children with short stature]. / 青春期矮身材儿童身高改善的药物治疗.

Short stature in puberty significantly affects the physical and mental health of adolescents. The continuous acceleration of skeletal maturation, caused by sex hormones during puberty, limits the time available for growth and poses a considerable challenge for the treatment of short stature. To date, there is still no standardized treatment protocol for this disorder. However, puberty is the last period to improve the final adult height. Currently, commonly used pharmacological treatments in clinical settings include recombinant human growth hormone, gonadotropin-releasing hormone analogs, and third-generation aromatase inhibitors. In recent years, personalized treatment aiming to improve the final adult height has become a key focus in clinical practice. This article provides a comprehensive summary of research on pharmacological therapies for height improvement in pubertal children with short stature, offering valuable insights for healthcare professionals.
