[PMID: 38779170 PMCID: PMC11109348 DOI: 10.1016/j.eclinm.2024.102637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 04/23/2024] [Accepted: 04/29/2024] [Indexed: 05/25/2024] Open
Abstract
Background Increased cerebrovascular morbidity was reported in adults born small for gestational age (SGA) who were treated with growth hormone (GH) during childhood compared to the general population. Yet, previous studies lacked an appropriate control group which is a major limitation. We prospectively studied cerebral white matter hyperintensities (WMHs) in adults born SGA at 12 years after cessation of childhood GH-treatment (SGA-GH), compared to appropriate controls. Methods In this prospective cohort study, performed between May 2016 and December 2020, total WMHs, periventricular WMHs (PVWMHs) and deep WMHs (DWMHs) were the primary outcomes of the study, they were qualitatively assessed using 3 Tesla (T) Magnetic Resonance Imaging (MRI) and scored using the Fazekas scale in SGA-GH adults and in 3 untreated control groups: adults born SGA with persistent short stature (SGA-S), adults born SGA with spontaneous catch-up growth to a normal height (SGA-CU) and adults born appropriate for gestational age with a normal height (AGA). Regression analyses were performed in the total cohort to evaluate the associations of GH-treatment and birth characteristics with WMHs. Findings 297 adults were investigated (91 SGA-GH, 206 controls). Prevalence of total WMHs was 53.8% (95% CI 43.1-64.3) in SGA-GH, 40.5% (95% CI 25.6-56.7) in SGA-S, 73.9% (95% CI 61.9-83.7) in SGA-CU and 41.1% (95% CI 31.1-51.6) in AGA adults. No statistically significant differences in total WMHs, PVWMHs and DWMHs were found between SGA-GH compared to SGA-S and AGA adults. Highest prevalence of all type of WMHs was found in SGA-CU adults compared to all groups. Higher prevalence of total WMHs was associated with lower birth weight standard deviation score (SDS), but not with GH-treatment. Interpretation Our findings suggest that GH-treatment in children born SGA has no negative impact on the prevalence of all type of WMHs at 12 years after GH cessation compared to appropriate controls. SGA-CU adults had the highest prevalence of all type of WMHs around age 30 years. Funding Novo Nordisk.

Abstract
RATIONALE Children born small for gestational age (SGA) not showing catch-up during the first two years of life reportedly show an impaired growth rate and adult height, as well as a worse metabolic outcome, mainly in terms of glycemic and lipid profile, compared to general population. In SGA children with short stature, treatment with recombinant growth hormone (GH) is currently recommended until adolescence; therefore, it may last long-term. STUDY METHODS The aim of the current study was to evaluate the auxological and metabolic effects and the safety of long-term recombinant GH treatment in SGA children. The study included 15 SGA children (5 F, 10 M; mean age: 6.78 yrs) treated with GH for at least 48 months. Growth and metabolic parameters, including glycemic and lipid profile, transaminases, and urycemia, were collected every six months. RESULTS Compared to baseline, SGA children showed a significant improvement in height, weight, and growth rate after four yaers of treatment with GH (p ≤ 0.002), being already evident after six months of treatment (p < 0.001). Noteworthy, patients showed a constant, significant improvement in height throughout the treatment, as it was significantly higher at each follow-up compared to the previous one, until 42 months of treatment, except at 30 months of treatment (p < 0.001 T6VST12; p < 0.01 T12VST18, T18VST24; p < 0.05 T30VST36, T36VST42). Considering metabolic parameters, compared to baseline, a recurring increase in glycemia (p ≤ 0.028 vs T30, T36, and T48) and decrease in AST (p ≤ 0.035 vs T36, T42, and T48) and an occasional decrease in LDL cholesterol (p ≤ 0.04 vs T24 and T42) and triglycerides (p = 0.008 vs T18) and increase in urycemia (p = 0.034 vs T42). Considering safety profile, treatment was well tolerated, as the most frequently reported adverse event was poor compliance (20%); no hyperglycemia, hypercholesterolemia or hyperstransaminasemia occurred throughout the treatment, CONCLUSIONS: Long-term GH treatment showed to be effective in improving height and growth rate in SGA children, with a positive impact of metabolic profile and a safety profile, although glycemia should be carefully monitored over time.

Abstract
CONTEXT Increased cerebrovascular morbidity was reported in adults born small for gestational age (SGA) who were treated with growth hormone (GH) during childhood compared to the general population. However, previous studies did not have an appropriate control group, which is a major limitation. OBJECTIVE To study cerebrovascular abnormalities (aneurysms, previous intracerebral hemorrhages and microbleeds) using magnetic resonance imaging (MRI) in adults born SGA at 12 years after cessation of childhood GH treatment (SGA-GH) compared to appropriate controls. METHODS In this single-center, prospective study, brain MRIs were performed between May 2016 and December 2020 on a 3T MRI system. MRI images were scored by 2 neuroradiologists who were blinded to patient groupings. Participants included adults born SGA previously treated with GH and 3 untreated control groups: adults born SGA with persistent short stature (SGA-S), adults born SGA with spontaneous catch-up growth to a normal height (SGA-CU) and adults born appropriate for gestational age with a normal height (AGA). The intervention was long-term GH treatment during childhood and the main outcome measure was cerebrovascular abnormalities. RESULTS A total of 301 adults were investigated. Aneurysms were found in 6 adults: 3 (3.6%) SGA-GH, 1 (2.9%) SGA-S and 2 (2.2%) AGA adults, without differences between SGA-GH adults and the controls. Previous intracerebral hemorrhages were only found in 2 SGA-S adults (4.8%). Microbleeds were found in 17 adults: 4 (4.3%) SGA-GH, 4 (9.5%) SGA-S, 3 (4.3%) SGA-CU and 6 (6.3%) AGA adults, without differences between SGA-GH adults and the controls. CONCLUSION Our findings suggest that SGA-GH adults at 12 years after GH cessation have no increased prevalence of cerebrovascular abnormalities compared to appropriate controls. Further research is needed to confirm our findings.

Abstract
PURPOSE The impacts of growth restriction and programming in the fetal stage on metabolic and bone health in children and adolescents are poorly understood. Moreover, there is insufficient evidence for the relationship between current growth status and metabolic components. Herein, we compared the growth status, metabolic and body compositions, and bone mineral density in Korean children and adolescents based on birth weight at gestational age. METHODS We studied 1,748 subjects (272 small for gestational age [SGA], 1,286 appropriate for gestational age [AGA], and 190 large for gestational age [LGA]; 931 men and 817 women) aged 10-18 years from the Korean National Health and Nutrition Examination Survey (KNHANES) V (2010-2011). Anthropometric measurements, fasting blood biochemistry, and body composition data were analyzed according to birth weight and gestational age. RESULTS The prevalence of low birth weight (14.7% vs. 1.2% in AGA and 3.2% in LGA, p<0.001) and current short stature (2.237 [1.296-3.861] compared to AGA, p=0.004) in SGA subjects was greater than that in other groups; however, the prevalence of overweight and obesity risks, metabolic syndrome (MetS), and MetS component abnormalities was not. Moreover, no significant differences were found in age- and sex-adjusted lean mass ratio, fat mass ratio, truncal fat ratio, bone mineral content, or bone density among the SGA, AGA, and LGA groups in Korean children and adolescents. CONCLUSION Our data demonstrate that birth weight alone may not be a determining factor for body composition and bone mass in Korean children and adolescents. Further prospective and longitudinal studies in adults are necessary to confirm the impact of SGA on metabolic components and bone health.

Abstract
Growth Hormone therapy has been shown to induce transient insulin resistance in children, and there is concern regarding the diabetogenic potential of GH therapy in children born small for gestational age (SGA). In this case, female patient born SGA with a weight of 2,750 g (-1.73 standard deviation (SD)) and length of 45.5 cm (-2.6 SD). The patient's father and paternal grandfather were diagnosed with type 2 diabetes mellitus. At 3 years of age, the patient presented with short stature; height and weight were 85 cm (-2.5 SD) and 13 kg (-0.19 SD), respectively. She was placed on GH therapy. At 11 years of age, her fasting blood glucose and hemoglobin A1c levels were 116 mg/dL and 7.4%, respectively. Blood test results were negative for anti-glutamic acid decarboxylase and anti-islet antigen-2 antibodies. The patient discontinued GH therapy and started diet therapy and oral metformin (500 mg/day) administration. Five months later, the hemoglobin A1c level was 5.3% and glycemic control further improved. To our knowledge, family history may be an important risk factor for GH-induced diabetes. So, the GH dosage for patients born SGA with family history of diabetes should be adjusted so as not to be too excessive, and long-term follow-up studies will be required to evaluate fully the effects of GH therapy for them.

Abstract
OBJECTIVES Childhood-onset craniopharyngiomas (CPs) have a high incidence of growth hormone deficiency (GHD) leading to growth failure and metabolic disorders. We aim to evaluate the benefits and risks of recombinant human growth hormone replacement therapy (GHRT) in postoperative children. METHODS We retrospectively analyzed auxological and metabolic parameters and adverse events before and after GHRT of 44 children after CP surgery. RESULTS The median duration of GHRT was 24 months (IQR, 12.5-36). Growth velocity (GV) increased significantly after different treatment duration (TD) compared with baseline (p<0.001) and attained the greatest GV of 12.06 ± 4.16 cm/year at TD6. The mean height standard deviation score (HtSDS) from -3.20 ± 1.16 at baseline improved significantly to -1.51 ± 1.32 at TD36 (p<0.001). There were significant increases in insulin-like growth factor-1 SDS (IGF-1SDS), insulin-like growth factor binding protein 3 SDS (IGFBP-3SDS), bone age (BA), and BA/chronological age (CA) (p<0.05). There was a significant reduction in waist-to-hip ratio (WHR), but there were no significant changes in weight SDS (WtSDS) or BMISDS. Low-density lipoprotein-cholesterol (LDL-C) levels and the incidence of hypercholesterolemia decreased (p<0.05). Three patients (6.8%) had tumor recurrence after 15, 30, and 42 months, respectively. A patient had residual tumor enlargement after 3 months. There was no adverse influence on glucose metabolism or any severe adverse events. CONCLUSIONS GHRT effectively accelerates GV, increases HtSDS, and improves lipid profiles without unfavorable effects on glucose metabolism. The benefits are clear and the risks of adverse events are low.

International Consensus Guideline on Small for Gestational Age (SGA): Etiology and Management from Infancy to Early Adulthood. Endocr Rev 2023; 44:539-565.

Abstract
This International Consensus Guideline was developed by experts in the field of SGA of 10 pediatric endocrine societies worldwide. A consensus meeting was held and 1300 articles formed the basis for discussions. All experts voted about the strengths of the recommendations. The guideline gives new and clinically relevant insights into the etiology of short stature after SGA birth, including novel knowledge about (epi)genetic causes. Besides, it presents long-term consequences of SGA birth and new treatment options, including treatment with gonadotropin-releasing hormone agonist (GnRHa) in addition to growth hormone (GH) treatment, and the metabolic and cardiovascular health of young adults born SGA after cessation of childhood-GH-treatment in comparison with appropriate control groups. To diagnose SGA, accurate anthropometry and use of national growth charts are recommended. Follow-up in early life is warranted and neurodevelopment evaluation in those at risk. Excessive postnatal weight gain should be avoided, as this is associated with an unfavorable cardio-metabolic health profile in adulthood. Children born SGA with persistent short stature < -2.5 SDS at age 2 years or < -2 SDS at age of 3-4 years, should be referred for diagnostic work-up. In case of dysmorphic features, major malformations, microcephaly, developmental delay, intellectual disability and/or signs of skeletal dysplasia, genetic testing should be considered. Treatment with 0.033-0.067 mg GH/kg/day is recommended in case of persistent short stature at age of 3-4 years. Adding GnRHa treatment could be considered when short adult height is expected at pubertal onset. All young adults born SGA require counseling to adopt a healthy lifestyle.

Childhood growth hormone treatment and metabolic and cardiovascular risk in adults born small for gestational age after growth hormone cessation in the Netherlands: a 12-year follow-up study. THE LANCET. CHILD & ADOLESCENT HEALTH 2022; 6:777-787. [PMID: 36122581 DOI: 10.1016/s2352-4642(22)00240-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 08/01/2022] [Accepted: 08/01/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Childhood growth hormone treatment has been associated with increased cardiovascular mortality and morbidity in adults born small for gestational age (SGA) compared with the general population, but these risks have not been compared with untreated control groups. We aimed to investigate longitundinal metabolic and cardiovascular health in adults born SGA after cessation of growth hormone treatment. METHODS We longitudinally investigated the metabolic and cardiovascular health profile of 167 adults born SGA and previously treated with growth hormone during the 12 years after growth hormone cessation. Metabolic and cardiovascular parameters were assessed with the frequently sampled intravenous glucose tolerance test, serum lipids and blood pressure were measured, body composition was determined by dual-energy x-ray absorptiometry, and visceral fat was measured by MRI. At approximately age 30 years, we compared the metabolic and cardiovascular health profile of adults born SGA and previously treated with growth hormone (SGA-GH) with 219 untreated adults: 127 born SGA with either persistent short stature (SGA-S) or spontaneous catch-up to typical adult stature (SGA-CU), and 92 born appropriate for gestational age. FINDINGS During 12 years of follow-up, SGA-GH adults maintained normal β-cell function (p=0·157 for the difference from growth hormone cessation to 12-year follow-up) and showed an increase in insulin sensitivity (p=0·002), fat mass (p<0·001), total cholesterol (p<0·001), and blood pressure (p<0·001). By around age 30 years, these parameters reached similar levels to those in SGA-S adults (insulin sensitivity p=0·242; fat mass p=0·449; total cholesterol p=0·616; systolic blood pressure p=0·523; diastolic blood pressure p=0·538). By around age 30 years, SGA-GH adults also had similar metabolic and cardiovascular health parameters to adults born appropriate for gestational age, with the exception of lower lean body mass (estimated marginal mean 44·67 kg [95% CI 43·54-45·80] in SGA-GH adults vs 47·65 kg [46·39-48·92] in adults born appropriate for gestational age) and higher concentrations of adverse serum lipids, such as cholesterol (4·75 mmol/L [4·55-4·95] vs 4·33 mmol/L [4·13-4·5]), which were present in all groups born SGA. Abdominal adiposity (visceral adipose tissue p=0·107; subcutaneous adipose tissue: p=0·244), liver fat fraction (p=0·104), and blood pressure (systolic blood pressure 0·927; diastolic blood pressure: 0·737) were similar between SGA-GH adults and all control groups. INTERPRETATION At approximately age 30 years, SGA-GH adults had a similar metabolic and cardiovascular health profile to untreated adults born SGA or appropriate for gestational age, indicating long-term metabolic and cardiovascular safety of growth hormone treatment for children born SGA with short stature.

[PMID: 36440208 PMCID: PMC9691665 DOI: 10.3389/fendo.2022.1041718] [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: 09/11/2022] [Accepted: 10/25/2022] [Indexed: 11/12/2022] Open
Abstract
During the last decades several lines of evidence reported the association of an adverse intrauterine environment, leading to intrauterine restriction, with future disease, such as obesity and metabolic syndrome, both leading to increased cardiovascular and cancer risk. The underlying explanation for this association has firstly been expressed by the Barker's hypothesis, the "thrifty phenotype hypothesis". According to this hypothesis, a fetus facing an adverse intrauterine environment adapts to this environment through a reprogramming of its endocrine-metabolic status, during the crucial window of developmental plasticity to save energy for survival, providing less energy and nutrients to the organs that are not essential for survival. This theory evolved to the concept of the developmental origin of health and disease (DOHaD). Thus, in the setting of an adverse, f. ex. protein restricted intrauterine environment, while the energy is mainly directed to the brain, the peripheral organs, f.ex. the muscles and the liver undergo an adaptation that is expressed through insulin resistance. The adaptation at the hepatic level predisposes to future dyslipidemia, the modifications at the vascular level to endothelial damage and future hypertension and, overall, through the insulin resistance to the development of metabolic syndrome. All these adaptations are suggested to take place through epigenetic modifications of the expression of genes without change of their amino-acid sequence. The epigenetic modifications leading to future obesity and cardiovascular risk are thought to induce appetite dysregulation, promoting food intake and adipogenesis, facilitating obesity development. The epigenetic modifications may even persist into the next generation even though the subsequent generation has not been exposed to an adverse intrauterine environment, a notion defined as the "transgenerational transfer of environmental information". As a consequence, if the increased public health burden and costs of non-communicable chronic diseases such as obesity, hypertension, metabolic syndrome and type 2 diabetes have to be minimized, special attention should be laid to the healthy lifestyle habits of women of reproductive age, including healthy diet and physical activity to be established long before any pregnancy takes place in order to provide the best conditions for both somatic and mental health of future generations.

Abstract
Children born small for gestational age (SGA) comprise a heterogeneous group due to the varied nature of the cause. Approximately 85-90% have catch-up growth within the first 4 postnatal years, while the remainder remain short. In later life, children born SGA have an increased risk to develop metabolic abnormalities, including visceral adiposity, insulin resistance, and cardiovascular problems, and may have impaired pubertal onset and growth. The third "360° European Meeting on Growth and Endocrine Disorders" in Rome, Italy, in February 2018, funded by Merck KGaA, Germany, included a session that examined aspects of short children born SGA, with three presentations followed by a discussion period, on which this report is based. Children born SGA who remain short are eligible for GH treatment, which is an approved indication. GH treatment increases linear growth and can also improve some metabolic abnormalities. After stopping GH at near-adult height, metabolic parameters normalize, but pharmacological effects on lean body mass and fat mass are lost; continued monitoring of body composition and metabolic changes may be necessary. Guidelines have been published on diagnosis and management of children with Silver-Russell syndrome, who comprise a specific group of those born SGA; these children rarely have catch-up growth and GH treatment initiation as early as possible is recommended. Early and moderate pubertal growth spurt can occur in children born SGA, including those with Silver-Russell syndrome, and reduce adult height. Treatments that delay puberty, specifically metformin and gonadotropin releasing hormone analogs in combination with GH, have been proposed, but are used off-label, currently lack replication of data, and require further studies of efficacy and safety.

Abstract
Growth hormone (GH) therapy dates back to 1958 and, though has shown an excellent safety profile in the short-term, has never ceased to raise concern about potential long-term side effects. In the last decade, a number of observational studies in different cohorts of young adult patients treated with GH during childhood have yielded conflicting results. The attention has mainly focused on three major potential risks associated with GH therapy: cancer, cardio and cerebrovascular diseases and diabetes. This review intends to provide a detailed overview of the main studies reporting long-term safety in subjects treated with rhGH therapy during childhood, highlighting the evidence for or against the risk of cancer, cardio and cerebrovascular diseases and diabetes.

Long-term follow up of carbohydrate metabolism and adverse events after termination of Omnitrope® treatment in children born small for gestational age. Ther Adv Endocrinol Metab 2021; 12:20420188211013121. [PMID: 34104396 PMCID: PMC8111548 DOI: 10.1177/20420188211013121] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 04/08/2021] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND Recombinant human growth hormone (rhGH) therapy can affect carbohydrate metabolism and lead to impaired glucose tolerance during treatment. In addition, short children born small for gestational age (SGA) are predisposed to metabolic abnormalities. This study assessed the long-term safety of rhGH (Omnitrope®) use in short children born SGA. METHODS This was a follow-up observational study of patients from a phase IV study. The baseline visit was the final visit of the phase IV study. Further visits were planned after 6 months (F1), 1 year (F2), 5 years (F3), and 10 years (F4). The primary objective was to evaluate the long-term effect of rhGH treatment on the development of diabetes mellitus; secondary objectives included incidence/severity of adverse events (AEs). RESULTS In total, 130 subjects were enrolled in the follow-up study; 99 completed F1, 88 completed F2, and 13 completed F3 (no subject reached F4). The full analysis set for evaluation comprised 118 patients (64 female). Mean (standard deviation) duration of follow up was 39.6 (24.4) months. No subject was newly diagnosed with diabetes. The results for carbohydrate metabolism parameters were consistent with this finding. A total of 144 AEs were reported in 54 subjects; these were mostly of mild-to-moderate intensity (96.5%) and not suspected to be related to previous rhGH treatment (94.4%). Serious AEs (n = 18) were reported in eight patients; three (in one patient) were suspected as possibly related to previous rhGH treatment (anemia, menorrhagia, oligomenorrhoea). One fatal event occurred (sepsis), which was judged as not related to previous rhGH treatment. CONCLUSIONS None of the participating subjects, who had all been previously treated with Omnitrope® in a phase IV study, developed diabetes during this follow-up study. In addition, no other unexpected or concerning safety signals were observed.

Abstract
BACKGROUND Children born small for gestational age (SGA) with catch-up growth are at high risk for developing obesity; however, the characteristics of body composition, especially fat distribution, before and after growth hormone (GH) treatment in SGA children without catch-up growth remains largely unknown. METHODS Anthropometric characteristics, body composition by dual-energy X-ray absorption, and fat distribution by computed tomography at the umbilical level were examined in 27 prepubertal short-stature children born SGA before and 1 year after GH treatment. RESULTS Before GH treatment, short-stature SGA children had lean phenotypes, and both visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were significantly lower than the age- and sex-matched Japanese reference values. Growth hormone treatment significantly increased height standard deviation scores (SDS), without affecting body mass index SDS. Percentage fat mass decreased with GH treatment; however, fat mass was not altered. Both VAT and SAT were significantly lower than the reference values after GH treatment. The ratio of VAT over SAT significantly increased by GH treatment. CONCLUSIONS Both VAT and SAT were within or below the age- and sex-matched Japanese reference values in short-stature children born SGA before and after GH treatment, indicating that GH treatment may not have unfavorable effects on adiposity in short-stature children born SGA, although it may alter fat distribution.

Abstract
BACKGROUND AND AIMS Short stature has been linked with the development of metabolic syndrome (MetS). However, only one study has been conducted in Latin American adults. We aimed to assess the association between short stature and MetS in workers of a private educational institution in Peru. In addition, we evaluated the association between height and surrogate markers of insulin resistance (IR). METHODS We performed an analytical cross-sectional study. We categorized the height in tertiles and evaluated MetS according to the Latin American Diabetes Association statement. We used the triglycerides and glucose (TyG) index and the triglycerides to HDL-cholesterol (TG/HDL-c) ratio as IR markers. We elaborated crude and adjusted Poisson generalized linear models to evaluate the association between height tertiles and MetS. For the IR markers, we carried out crude and adjusted linear regressions. RESULTS We analyzed 1080 participants and the overall prevalence of MetS was 16.2%. In the adjusted Poisson generalized linear model, using the high tertile as a reference, we found statistically significant differences in the prevalence of MetS with the low and intermediate tertile (aPR = 2.03; 95%CI: 1.48-2.77 and aPR = 1.41; 95%CI: 1.01-1.99; respectively). In the gender-stratified analysis, we found statistical significance between height and MetS when comparing high and low tertile for both genders. For IR markers, we found an inverse association between the height and TyG index (aβ = -0.14; 95%CI: 0.19 to -0.10) and TG/HDL-c ratio (aβ = -0.62; 95%CI: 0.84 to -0.39). When we stratified by gender, the association for both secondary outcomes and height remained statistically significant in both groups. CONCLUSIONS We found an association between short stature and the prevalence of MetS and IR markers. We need studies with national representative samples to define the threshold of short stature with better sensitivity and specificity for the screening of MetS.

Abstract
BACKGROUND In children born small for gestational age (SGA) with persistent short stature, 2 years of gonadotropin-releasing hormone analogue (GnRHa), in addition to long-term growth hormone (GH) treatment, can improve adult height. We assessed safety on metabolic and bone health of GnRHa/GH treatment during 5 years after cessation of GH. METHODS A total of 363 young adults born SGA, previously treated with combined GnRHa/GH or GH-only, were followed for 5 years after attainment of adult height at GH cessation and 2 and 5 years thereafter. Data at 5 years after GH cessation, at age 21 years, were also compared with 145 age-matched adults born appropriate for gestational age (AGA). Frequently sampled intravenous glucose tolerance (FSIGT) tests were used to assess insulin sensitivity, acute insulin response, and β-cell function. Body composition and bone mineral density (BMD) was determined by dual-energy x-ray absorptiometry (DXA) scans. FINDINGS In the GnRHa/GH and GH-only groups, fat mass increased during the 5 years after GH cessation, but the changes in FSIGT results, body composition, blood pressure, serum lipid levels, and BMD were similar in both groups. At age 21 years, the GnRHa/GH group had similar fat mass, FSIGT results, blood pressure, serum lipid levels and BMD-total body as the GH-only group and the AGA control group, a higher BMD-lumbar spine and lower lean body mass than the AGA control group. INTERPRETATION This study during 5 years after GH cessation shows that addition of 2 years of GnRHa treatment to long-term GH treatment of children short in stature born SGA has no unfavorable effects on metabolic and bone health in early adulthood.

Abstract
Background An increasing body of evidence supports the view that both an adverse intrauterine milieu and rapid postnatal weight gain in children born small for gestational age (SGA) contribute towards the risk for the development of chronic diseases in adult life. Content The aim of this review was to identify and summarize the published evidence on metabolic and cardiovascular risk, as well as risk of impaired cardiac function, intellectual capacity, quality of life, pubertal development and bone strength among children born SGA. The review will then address whether growth hormone (GH) therapy, commonly prescribed to reduce the height deficit in children born SGA who do not catch up in height, increases or decreases these risks over time. Summary Overall, there are limited data in support of a modest beneficial effect of GH therapy on the adverse metabolic and cardiovascular risk observed in short children born SGA. Evidence to support a positive effect of GH on bone strength and psychosocial outcomes is less convincing. Outlook Further evaluation into the clinical relevance of any potential long-term benefits of GH therapy on metabolic and cardiovascular endpoints is warranted.

[PMID: 31512772 DOI: 10.1111/cen.14095] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 09/04/2019] [Accepted: 09/09/2019] [Indexed: 11/30/2022]
Abstract
BACKGROUND Growth hormone treatment increases glomerular filtration rate (GFR), as serum IGF-I stimulates the renin-angiotensin system. Infants born with a low birth weight have a smaller number of nephrons, which cause a lower GFR, a higher blood pressure and a higher albumin-to-creatinine ratio in early adulthood. METHOD A total of 261 young adults born SGA, previously treated with growth hormone (SGA-GH), were longitudinally followed. Glomerular filtration rate, based on serum creatinine levels, was determined at cessation of GH treatment and at 6 months, 2 years and 5 years thereafter. Glomerular filtration rate, blood pressure and urinary albumin-to-creatinine ratio at 5 years after cessation of GH were compared with untreated age-matched controls (56 untreated short subjects born SGA [SGA-S], 118 subjects born SGA with spontaneous catch-up growth [SGA-CU], 135 subjects born appropriate for gestational age [AGA]). RESULTS Glomerular filtration rate decreased significantly only during the first 6 months after cessation of GH treatment, while remaining well within the normal range (124.6 vs 120.2 mL/min/1.73 m2 , P < .001). SGA-GH adults had a similar GFR, blood pressure and urinary albumin-to-creatinine ratio as the healthy controls born SGA and AGA. CONCLUSION In conclusion, our 5 years longitudinal follow-up study shows a decrease in GFR during 6 months after GH cessation, but thereafter GFR remained stable and within the normal range. Glomerular filtration rate, blood pressure and urinary albumin-to-creatinine ratio at 21 years of age were similar in GH-treated young adults born SGA and untreated controls born SGA or AGA. We conclude that long-term GH treatment in children born SGA has no unfavourable effects on kidney function in early adulthood. PRÉCIS: We present a longitudinal study on kidney function in the follow-up of growth hormone-treated young adults who were born small for gestational age.

Abstract
PURPOSE The aim of this registry study was to analyze the long-term safety and effectiveness of recombinant human growth hormone (rhGH) in South Korean pediatric patients (≥2 years of age) with growth hormone deficiency GHD) of idiopathic or organic etiology, idiopathic short stature, Turner syndrome, small for gestational age and chronic renal failure. METHODS The study patients were followed-up till two years after the epiphyseal closure, with visits scheduled every six months. The outcome measures included the incidence of adverse events (AEs, in particular, neoplasia, glucose intolerance and hypothyroidism), as well as height standard deviation score (Ht SDS) and annual height velocity. The results of the interim analysis of a 5-year accumulated data for 2,024 patients (7,342 patient-years, PY) are presented. RESULTS A total of 14 neoplasms were diagnosed (191/100,000 PY); 7 out of 9 malignancies were recurrent craniopharyngioma found in patients with organic GHD. Seven cases of glucose intolerance (95/100,000 PY) and 22 cases of hypothyroidism (300/100,000 PY) were detected; about half of the cases (4 and 10 cases each) were considered to be related with rhGH treatment. Most of the growth-retarded patients showed continuous improvement in Ht SDS, with the most prominent effect observed within a year of treatment initiation. The beneficial effect of rhGH on Ht SDS gain was maintained for 2-4 years. CONCLUSIONS The incidence of AEs of interest in rhGH-treated patients was low, and most of the neoplasms were benign and/or non-related to rhGH. Most patients benefited from the therapy in terms of height increment.

Abstract
Children born small for gestational age (SGA), defined as a birth weight and/or length below -2 SD score (SDS), comprise a heterogeneous group. The causes of SGA are multifactorial and include maternal lifestyle and obstetric factors, placental dysfunction, and numerous fetal (epi)genetic abnormalities. Short-term consequences of SGA include increased risks of hypothermia, polycythemia, and hypoglycemia. Although most SGA infants show catch-up growth by 2 years of age, ∼10% remain short. Short children born SGA are amenable to GH treatment, which increases their adult height by on average 1.25 SD. Add-on treatment with a gonadotropin-releasing hormone agonist may be considered in early pubertal children with an expected adult height below -2.5 SDS. A small birth size increases the risk of later neurodevelopmental problems and cardiometabolic diseases. GH treatment does not pose an additional risk.

Abstract
GH therapy in pediatric patients with Prader-Willi syndrome (PWS) improves body composition, but discontinuation of GH after achieving adult height has been implicated in its deterioration. Although there is evidence for the deleterious effects of visceral adipose tissue (VAT) rather than subcutaneous adipose tissue (SAT) on the development of obesity-related complications, the effects of GH discontinuation on fat distribution in adults with PWS has not been fully investigated. Therefore, we utilized dual-energy X-ray absorptiometry (DEXA) and abdominal computed tomography (CT) to compare the fat distribution between before and 6 months or 12 months after the cessation of GH therapy in 7 adult PWS patients. GH therapy was initiated at a mean age of 4.1 ± 1.4 years and discontinued at a mean age of 18.9 ± 1.8 years. Serum IGF-1 levels were decreased by discontinuation of GH therapy. Fat mass was significantly increased 6 and 12 months after GH cessation, whereas muscle mass and bone mineral density were unchanged during both study periods. Abdominal CT analysis revealed that elevations in fat mass were due to increases in VAT rather than SAT. Circulating low-density lipoprotein (LDL) cholesterol levels were significantly elevated 6 months after GH cessation. In conclusion, discontinuation of GH therapy caused rapid increases in visceral adipose tissue and LDL cholesterol levels. These findings indicate that continuation of GH therapy may be a therapeutic option to maintain body composition; however, further studies regarding the long-term benefits and adverse effects of GH therapy in adults with PWS are required.

Abstract
Human growth is a very complex phenomenon influenced by genetic, hormonal, nutritional and environmental factors, from fetal life to puberty. Although the GH-IGF axis has a central role with specific actions on growth, numerous genes are involved in the control of stature. Genome-wide association studies have identified >600 variants associated with human height, still explaining only a small fraction of phenotypic variation. Since short stature in childhood is a common reason for referral, pediatric endocrinologists must be aware of the multifactorial and polygenic contributions to height. Multiple disorders characterized by growth failure of prenatal and/or postnatal onset due to single gene defects have been described. Their early diagnosis, facilitated by advances in genomic technologies, is of upmost importance for their clinical management and to provide genetic counseling. Here we review the current clinical and genetic information regarding different syndromes and hormone abnormalities with proportionate short stature as the main feature, and provide an update of the approach for diagnosis and management.

Abstract
Abstract
Introduction: Children born small for gestational age (SGA) have increased prevalence of metabolic syndrome, diabetes mellitus type 2 (DM2), hypertension and cardiovascular and cerebrovascular events in adulthood.
Patients and Methods: In 100 children born SGA, and in second cohort having 32 obese children born in term with normal birth weight and height, anthropometric measurements and biochemical metabolic profiles were analysed. The Homeostasis Model Assessment - Insulin Resistance and Sensitivity (HOMA-IR and IS) were calculated.
Results: Four overweight/obese children (M:F=3:1) with normal height were found among 100 SGA children. The body mass index (BMI) in all 4 children was above the 98th percentile and the mean BMI z-score was (2.04±0.30 SDS). The HOMA-IR index in all four children was increased: 1.26-2.65 (>1). Two teenagers had significant hyperinsulinemia (198.00 uIU/ml and 275 uIU/ml) and were treated with metformin. Two girls needed only a diet and increased physical activity. The mean values of HOMA-IR (1.26-2.65; N< 1) and IS (58 ±17.12) in fo-ur SGA overweight/obese children who caught-up growth had indistinguishable values with the group of 32 (M: F=21:11) obese children (HOMA-IR 1.83±1.2 SDS; IS 82.99±64.53 SDS) born in term with normal birth weight and height.
Conclusions: SGA born children are usually thin; nevertheless we found overweight and obesity in 4% of the patients. Two of those children have metabolic syndrome. Excess weight, obesity and metabolic syndrome in SGA children result with increase of their inherent risk for DM2, cardiovascular and cerebrovascular diseases in adulthood.

Abstract
BACKGROUND Growth hormone treatment reduces blood pressure and lipid concentrations. We assessed long-term changes in blood pressure, lipid concentrations, and carotid intima media thickness over a 5-year period after cessation of growth hormone treatment in adults born small for gestational age. METHODS We did a longitudinal observational study at a medical centre in the Netherlands between April 1, 2004, and April 1, 2016. We included adults born small for gestational age who were treated with growth hormone (1 mg/m2 per day); treatment started during childhood until adult height. Participants were evaluated at cessation of treatment, and 6 months, 2 years, and 5 years later. We compared cardiovascular risk factors with untreated controls from the PROGRAM study. FINDINGS We included 199 participants born small for gestational age and treated with growth hormone along with 285 controls: 51 untreated short adults born small for gestational age, 92 untreated adults born small for gestational age with spontaneous catch-up growth, and 142 adults born appropriate for gestational age. In the 6 months after treatment cessation, systolic blood pressure increased temporarily from 113·00 mm Hg (95% CI 111·18-114·82) to 116·92 mm Hg (115·07 to 118·77; p<0·001) and diastolic blood pressure increased temporarily from 62·19 mm Hg (60·99-63·38) to 66·51 mm Hg (65·14-67·89; p<0·001). At 5 years after treatment cessation, mean systolic blood pressure was 109·2 mm Hg (105·5-113·0) and mean diastolic blood pressure was 63·4 mm Hg (60·9-65·9), similar to the values at cessation. Lipid concentrations were non-significantly higher 5 years after treatment cessation (p values 0·09-0·21) than at treatment cessation. Cessation of growth hormone had no effect on carotid intima media thickness. At 5 years after cessation, total cholesterol was lower in adults treated with growth hormone (mean 4·21 mmol/L, 95% CI 4·04-4·38) than in untreated short adults born small for gestational age (4·66 mmol/L, 4·42-4·92; p=0·0030), as was mean LDL cholesterol (2·28 mmol/L, 2·14-2·43 vs 2·85 mmol/L, 2·62-3·10; p<0·0001); blood pressure and carotid intima media thickness did not differ between these two groups (p values >0·12). At 5 years after cessation, systolic blood pressure, diastolic blood pressure, lipid concentrations, and carotid intima media thickness of adults treated with growth hormone were not different to those in adults born small for gestational age who had spontaneous catch-up growth or adults born appropriate for gestational age. INTERPRETATION Long-term growth hormone treatment in children born small for gestational age has no unfavourable effects on cardiovascular health in early adulthood and improves lipid profiles.

Abstract
Growth hormone (GH) was first isolated from cadaver pituitary glands, requiring laborious and expensive collection of glands, followed by extraction and purification of the hormone. This limited supply restricted its use to children with severe GH deficiency who were treated with low dosages and suboptimal schedules. The development of recombinant DNA-derived GH, allowed the production of virtually unlimited amounts of GH, leading to the approval for therapy for a large number of childhood conditions characterized by non-GH deficient short stature. The aim of this review is to provide a critical overview on the daily use of GH in two paradigmatic conditions of non-GH deficient short stature which are children born small for gestational age and with idiopathic short stature, highlighting the available strength of evidence for efficacy and safety.

Abstract
CONTEXT Short children born small for gestational age (SGA) have below-average bone mineral density (BMD). Growth hormone (GH) treatment improves height and BMD in short SGA children. Longitudinal data on BMD in adults born SGA, after GH cessation (GH-stop), are lacking. OBJECTIVE To determine BMD in young adults born SGA during 5 years after GH-stop. METHODS In 173 GH-treated adults born SGA (SGA-GH), BMD of total body (BMDTB) and bone mineral apparent density of lumbar spine (BMADLS) were measured longitudinally at adult height (AH) and 6 months, 2 years, and 5 years thereafter. At 5 years after GH-stop (age 21 years), data were compared with 45 untreated short SGA adults (SGA-S), 59 SGA adults with spontaneous catch-up (SGA-CU), and 81 adults born appropriate for gestational age (AGA). RESULTS At GH-stop (mean age 16.4 years), estimated mean (standard error) BMDTB standard deviation score (SDS) was -0.40 (0.1) in males and -0.51 (0.1) in females, followed by a trend toward a decrease of BMDTB in males to -0.59 (0.1) at 5 years after GH-stop (P = 0.06), whereas it remained stable in females [-0.57 (0.1); P = 0.33]. At GH-stop, BMADLS SDS was -0.01 (0.1) in males and -0.29 (0.1) in females, followed by a decrease in males and females to -0.38 and -0.55, respectively, at 5 years after GH-stop (P < 0.001). At 5 years after GH-stop, BMDTB and BMADLS in SGA-GH were similar compared with SGA-S, SGA-CU, and AGA. CONCLUSION After GH-stop, there is a gradual decline of BMADLS, but at the age of 21 years, BMDTB and BMADLS are similar as in untreated short SGA adults.
