Abstract
OBJECTIVE The short-term safety of methylphenidate (MPH) has been widely demonstrated; however the long-term safety is less clear. The aim of this study was to investigate the safety of MPH in relation to pubertal maturation and to explore the monitoring of bone age. METHOD Participants from ADDUCE, a two-year observational longitudinal study with three parallel cohorts (MPH group, no-MPH group, and a non-ADHD control group), were compared with respect to Tanner staging. An Italian subsample of medicated-ADHD was further assessed by the monitoring of bone age. RESULTS The medicated and unmedicated ADHD groups did not differ in Tanner stages indicating no higher risk of sexual maturational delay in the MPH-treated patients. The medicated subsample monitored for bone age showed a slight acceleration of the bone maturation after 24 months, however their predicted adult height remained stable. CONCLUSION Our results do not suggest safety concerns on long-term treatment with MPH in relation to pubertal maturation and growth.

Abstract
OBJECTIVE In recent years, it has been emphasized that various growth factors that affect neurogenesis may lead to ADHD. In this study, we aimed to investigate the role of VEGF, IGF-1, and HIF-1α growth factors in the etiopathogenesis of ADHD. METHOD Levels of VEGF, IGF-1, and HIF-1α were compared between 40 ADHD children and 40 healthy children, aged 7 to 13 years. RESULT VEGF, IGF-1, and HIF-1α levels did not significantly differ between the groups. There was a negative correlation between serum VEGF levels and the parent-rated T-DSM-IV-S (AD) subscale. There was a positive correlation between serum IGF-1 levels and the parent-rated T-DSM-IV-S (AD) subscale, and SDQ (ES) subscale. CONCLUSION Given our limitations and the fact that some of our findings differ from those of other studies, it is evident that this area requires additional research with larger samples.

Abstract
BACKGROUND The use of stimulant medications for treatment of ADHD has raised concern as to whether they adversely impact linear growth. Previous studies have indicated that stimulant medications may suppress growth for a short period after treatment initiation; however, more information is needed to evaluate the long-term effects on final adult stature. This mini review aims to evaluate the effect of stimulant medications on final adult height in children with ADHD. CONTENTS We performed a literature review across PubMed/MEDLINE database. Only articles that included data on final adult height or near final adult height (age≥16 or 17 years) were included. SUMMARY Early studies investigating the long-term impacts of stimulant medications observed growth suppression during the active treatment period, but when comparing final adult height, there was no difference between the control and ADHD groups. A recent larger comprehensive study (Multimodal Treatment of ADHD study) has suggested that the long-term use of significant doses of stimulants during childhood may compromise final adult height to a clinically significant degree when comparing adult height across three long-term patterns of stimulant treatment (Consistent, Intermittent, Negligible). The consistent use subgroup was significantly shorter than other subgroups. OUTLOOK For children with ADHD, a significant long-term dose of stimulant treatment should be used with caution to avoid diminishing adult height potential. Pediatric endocrinologists should consider chronic use of stimulants as a factor contributing to reduced adult height.

Abstract
CONTEXT The trends in hormone indices of children with attention deficit hyperactivity disorder (ADHD) who received long-term medication treatment remains controversial. OBJECTIVE This prospective study aimed to examine the changes in the growth hormone and thyroid hormone systems among children with ADHD undergoing various medication treatments. METHODS In total, 118 children who were diagnosed with ADHD and were drug-naive were observed naturalistically over 12 months. Of them, 22 did not receive any medication, while 39, 40, and 17 were treated with low doses of short-acting methylphenidate (MPH) (14 ± 6.7 mg/day), osmotic-release oral system (OROS) long-acting MPH (32 ± 9.6 mg/day), and atomoxetine (29.2 ± 9.7 mg/day), respectively. Blood samples were obtained at both the baseline and the endpoint (month 12) to measure serum levels of insulin-like growth factor 1 (IGF-1), IGF binding protein 3 (IGFBP-3), prolactin, thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and free T4. RESULTS Trends for IGF-1, IGFBP-3, prolactin, TSH, T3, T4, and free T4 levels were similar among the 4 groups. Changes in serum levels of IGF-1 were positively correlated with changes in height and weight of all the children with ADHD. However, patients who received MPH treatment had less body weight gain than the nonmedicated group. The ratio of MPH doses to body weight was inversely correlated with the increment in height. CONCLUSION There were no changes in thyroid or growth hormones associated with the low doses of ADHD medications used in this study within 1 year's duration. Nonetheless, patients' growth and the appropriateness of drug dosage should be closely monitored.

Effect of Atomoxetine on Behavioral Difficulties and Growth Development of Primary School Children with Attention-Deficit/Hyperactivity Disorder: A Prospective Study. CHILDREN 2022; 9:children9020212. [PMID: 35204932 PMCID: PMC8870549 DOI: 10.3390/children9020212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 02/03/2022] [Accepted: 02/04/2022] [Indexed: 11/16/2022]
Abstract
(1) Objective: Atomoxetine is a selective norepinephrine reuptake inhibitor used to treat attention-deficit/hyperactivity disorder (ADHD) in children over six years old. Although it is common knowledge that primary school children with ADHD often present with difficulties in the morning prior to school and in the evening, these two periods, and the family interactions they involve, are often neglected in studies of ADHD. Questionnaire–Children with Difficulties (QCD) has been widely used in China to evaluate parents’ perceptions of ADHD and patients’ daily behaviors during different times. In the long term, the efficacy and safety of atomoxetine have been well established in previous studies. Still, the short-term effects of atomoxetine treatment on serum growth parameters, such as IGF-1, IGFBP-3, and thyroid function, are not well documented. Therefore, this study was the first one using the QCD to quantify the efficacy of atomoxetine treatment in the morning prior to school and in the evening, and has investigated the possible influence on the growth parameters of Chinese primary school children with ADHD. (2) Method: This prospective study was conducted at the Department of Pediatrics at the Affiliated Hospital of Jiangnan University from August 2019 to February 2021. Changes in the children’s behavior and core ADHD symptoms following treatment were assessed using three parent-reported questionnaires, including Children with Difficulties (QCD), the Swanson, Nolan, and Pelham IV scale (SNAP-IV), and the Conners’ parents rating scales (CPRS). The height, weight, and body mass index (BMI) were measured and corrected to reflect the standard deviations (SDS) in Chinese children based on age and gender. Serum growth parameters, such as insulin-like growth factor 1 (IGF-1), insulin-like growth factor-binding protein 3 (IGFBP-3), and thyroid function, were also measured to assess the children’s growth development. Any adverse drug reactions were assessed every three weeks. (3) Result: Finally, 149 children were enrolled in this study, and they completed 12 weeks of atomoxetine treatment. The QCD results indicated that the atomoxetine treatment could significantly alleviate behavioral difficulties in primary children with ADHD, especially in the morning prior to school (p < 0.001, r = 0.66) and in the evening (p < 0.001, r = 0.73). A statically significant decrease in weight SDS (p < 0.05) was noted during treatment, but the effect size was slight (r = 0.09). The atomoxetine treatment had no significant impact on height SDS, BMI SDS, and serum growth parameters, such as the levels of IGF-1, IGFBP-3, and thyroid function. The SNAP-IV results showed a significant improvement in the core symptoms of ADHD, while the CPRS results indicated a significant improvement in controlling ADHD symptoms across two different domains, learning problems (r = 0.81) and hyperactivity (r = 0.86). No severe adverse reactions were observed in the course of treatment, and the most common adverse reactions were gastrointestinal symptoms. (4) Conclusions: Atomoxetine is an effective and safe treatment for primary school children with ADHD. In China, it may be an excellent choice to alleviate parenting stress and improve the condition of primary school children with ADHD. Moreover, our study indicated that the serum levels of IGF-1 and IGFBP-3 were within the normal range in newly diagnosed ADHD children, and atomoxetine will not affect the serum concentration of growth parameters, such as IGF-1, IGFBP-3, and thyroid function, in the short term. However, the treatment may reduce appetite, resulting in a reduction in the Children’s weight for a short period. Further observational studies to monitor the long-term effects of atomoxetine on primary school children are recommended.

Abstract
BACKGROUND Genes, hormones and factors such as nutrition and psychosocial environment affect growth. OBJECTIVE What is the significance of various psychosocial factors on growth? METHODS Evaluation of results of a working meeting of paediatric endocrinologist with current literature research. RESULTS Psychosocial deprivation in children can be associated with growth hormone deficiency (GHD) and short stature. GHD can be reversed by a change of environment and psychosocial support. War and migration are often associated with underweight, growth disturbances and poor health care. These factors can improve after the end of conflicts, but children often remain too short. Consumption of alcohol or opiates during pregnancy are associated with lower birth weight and increased risk of early and small for gestational age (SGA) childbirth. Children with attention deficit hyperactivity disorder show a slight slowdown in growth after they started stimulant therapy. However, they reach normal adult height. CONCLUSIONS In children with idiopathic short stature, psychosocial causes should be taken into account in the differential diagnosis. Notably there is an increased risk of growth disturbances in children from conflict regions or after prenatal drug exposure.

Abstract
Objectives It remains unclear whether methylphenidate (MPH) has yadverse effects on growth in children. This study aimed to investigate the association of MPH with serum biological markers of growth in children with attention-deficit/hyperactivity disorder (ADHD). Methods The present study included 103 children with ADHD (64 drug-naive children, 39 MPH-treated children) and 112 control subjects. Children with ADHD were diagnosed on the basis of a semi-structured interview. Levels of biochemical markers of growth, including insulin-like growth factor-I, thyroid stimulating hormone (TSH), free T4, calcium, phosphorus, alkaline phosphatase, vitamin D, hemoglobin, total protein, albumin, total cholesterol, and hematocrit were measured in these individuals. Results Except in case of TSH, no intergroup differences were found in the levels of the growth markers. The levels of TSH were found to be lower in the MPH-treated boys with ADHD than in the drug-naive and control groups (p < 0.05), although the levels of TSH in all the groups were within normal limits. Conclusion In this cross-sectional study, no significant association was found between MPH and growth markers. This calls for the need to carry out prospective longitudinal research studies in the future that investigate the effect of MPH on the growth trajectory in children.

Abstract
Objectives: To determine the effects of methylphenidate treatment on child growth in Thai pediatric patients with attention-deficit/hyperactivity disorder (ADHD). Methods: The medical records of children and adolescents with ADHD, between 5 and 18 years of age, who received pharmacological treatment with methylphenidate as a sole psychiatric medication for ≥1 year between 2001 and 2018 at the Rajanagarindra Institute of Child Development, Thailand, were retrospectively reviewed. Data on anthropometric parameters and methylphenidate use were extracted. Height and weight were converted to age- and gender-corrected standard scores (z-scores) using norms from the Thai pediatric population. Changes in height and weight z-scores were assessed using a paired t-test or one-way repeated measures ANOVA with the Bonferroni correction. Results: In this retrospective observational study, 911 children and adolescents were eligible, with the mean age of 95.0 ± 19.5 months at baseline, the cumulative duration of methylphenidate treatment of 39.4 ± 23.5 months, and the average daily dosage of 14.1 ± 6.2 mg/day. Comparative analysis found no statistically significant change in height z-scores between baseline and last recorded measurement (mean difference = 0.0017, confidence interval [95% CI] = -0.0004 to 0.0038, p = 0.107), while a slight, but significant increase in weight z-scores was observed (mean difference = 0.0271, 95% CI = 0.0179-0.0362, p < 0.001). Longitudinal analysis observed that weight z-scores were significantly decreased during the first year of therapy, but regained in the second year and continued to increase in subsequent years of therapy. Conclusion: Treatment with methylphenidate in our cohort of Thai pediatric patients with ADHD was not associated with growth deficits, except for a slightly significant decrease in weight during the first year of therapy.

Abstract
Methylphenidate is a first-line therapy for attention deficit hyperactivity disorder, the most prevalent neuropsychiatric disorder of childhood. The compound is a piperidine and the D-threo-isomer is considered the biologically active form. The compound is available in multiple short- and long-acting preparations, having different delivery systems leading to varying kinetics without clear superiority in efficacy or tolerability at the group level. Common adverse effects are insomnia, appetite disturbance, stomach ache, headache and dizziness. Its mechanism of action is linked to the monoamines dopamine and norepinephrine. The compound appears to predominantly increase the synaptic concentration of dopamine, presumably via inhibition of the dopamine transporter DAT1. There also appears to be effects on presynaptic vesicular trafficking and distribution of dopamine. Both immediate- and sustained-release preparations of methylphenidate have proven efficacy in children and adults with attention deficit hyperactivity disorder. Analysis of the National Institutes of Health-sponsored multimodal treatment study of attention deficit hyperactivity disorder supports a combined medication and behavioral therapy approach.

Abstract
BACKGROUND Growth hormone (GH) treatment has become a frequently applied growth promoting therapy in short children born small for gestational age (SGA). Children born SGA have a higher risk of developing attention deficit hyperactivity disorder (ADHD). Treatment of ADHD with methylphenidate (MP) has greatly increased in recent years, therefore more children are being treated with GH and MP simultaneously. Some studies have found an association between MP treatment and growth deceleration, but data are contradictory. OBJECTIVE To explore the effects of MP treatment on growth in GH-treated short SGA children METHODS Anthropometric measurements were performed in 78 GH-treated short SGA children (mean age 10.6 yr), 39 of whom were also treated with MP (SGA-GH/MP). The SGA-GH/MP group was compared to 39 SGA-GH treated subjects. They were matched for sex, age and height at start of GH, height SDS at start of MP treatment and target height SDS. Serum insulin-like growth factor-I (IGF-I) and IGF binding protein-3 (IGFBP-3) levels were yearly determined. Growth, serum IGF-I and IGFBP-3 levels during the first three years of treatment were analyzed using repeated measures regression analysis. RESULTS The SGA-GH/MP group had a lower height gain during the first 3 years than the SGA-GH subjects, only significant between 6 and 12 months of MP treatment. After 3 years of MP treatment, the height gain was 0.2 SDS (± 0.1 SD) lower in the SGA-GH/MP group (P = 0.17). Adult height was not significantly different between the SGA-GH/MP and SGA-GH group (-1.9 SDS and -1.9 SDS respectively, P = 0.46). Moreover, during the first 3 years of MP treatment IGF-I and IGFBP-3 measurements were similar in both groups. CONCLUSION MP has some negative effect on growth during the first years in short SGA children treated with GH, but adult height is not affected.

Abstract
O presente estudo avaliou a influência de drogas estimulantes usadas no déficit de atenção e hiperatividade no crescimento estatural. Os autores procederam a uma revisão de literatura coletando artigos publicados sobre déficit de atenção e hiperatividade e sua relação com a baixa estatura. A fonte consultada foi o PubMed e o tópico levantado foi "Crescimento e Metilfenidato"/"Déficit de atenção e hiperatividade versus baixa estatura"/"Metilfenidato e distúrbios de crescimento". Os transtornos de atenção e hiperatividade constituem-se em situações clínicas difíceis, por interferir no bem-estar da criança e no seu relacionamento social, com prejuízos de seu desenvolvimento escolar. Uma vez feito o diagnóstico, as medicações estimulantes como o metilfenidato têm papel primordial no tratamento, mas muito se teme com relação a certos efeitos colaterais, particularmente a perda de peso e a perda estatural. Revisou-se uma série de publicações a respeito e pôde-se verificar que não há consenso sobre tais efeitos colaterais, mas que, mesmo quando ocorrem, não são suficientemente intensos para impedir o tratamento. Um julgamento da relação custo-benefício da medicação é sempre apropriado, mas os benefícios obtidos com a medicação e com a melhora do rendimento escolar e das relações sociais da criança não devem ser esquecidos. Uma cuidadosa monitorização da curva pondoestatural permite que o médico vigie com segurança o tratamento prescrito e possa tomar decisões se julgar que o prejuízo estatural compromete o bem-estar do paciente.

OBJECTIVE Stimulant medications are effective treatments for attention-deficit/hyperactivity disorder, but concerns remain about their effects on growth. METHOD We provide a quantitative analysis of longitudinal studies about deficits in expected growth among children with attention-deficit/hyperactivity disorder treated with stimulant medication. Study selection criteria were use of DSM criteria or clear operational definitions for hyperactivity or minimal brain dysfunction; outcome measures including raw, standardized, or percentile measurement of change in height and/or weight; first assessment of effects on growth occurred during childhood; and follow-up for at least 1 year. For issues not suitable for quantitative analyses, we provide a systematic, qualitative review. RESULTS The quantitative analyses showed that treatment with stimulant medication led to statistically significant delays in height and weight. This review found statistically significant evidence of attenuation of these deficits over time. The qualitative review suggested that growth deficits may be dose dependent, deficits may not differ between methylphenidate and amphetamine, treatment cessation may lead to normalization of growth, and further research should assess the idea that attention-deficit/hyperactivity disorder itself may be associated with dysregulated growth. CONCLUSIONS Treatment with stimulants in childhood modestly reduced expected height and weight. Although these effects attenuate over time and some data suggest that ultimate adult growth parameters are not affected, more work is needed to clarify the effects of continuous treatment from childhood to adulthood. Although physicians should monitor height, deficits in height and weight do not appear to be a clinical concern for most children treated with stimulants.

Abstract
OBJECTIVE To investigate if there are any disease-related or methylphenidate-induced aberrations in growth parameters, growth hormone insulin-like growth factor (IGF)-I, IGFBP-3 axis and the thyroid function tests in children with attention deficit hyperactivity disorder (ADHD). METHODS Newly diagnosed and untreated prepubertal children with ADHD were longitudinally followed before and approximately every 4 months after methylphenidate treatment for up to 16 months. Height SDS, weight SDS, BMI SDS, serum GH, IGF-I, IGFBP-3, T4, free T4, T3, and TSH were measured at each visit. RESULTS All of the examined parameters were within normal limits for age before treatment. Methylphenidate treatment did not significantly affect SDS of height, weight, BMI, IGF-I and IGFBP-3 in the long run. Serum T4 and free T4 levels showed modest reductions within normal limits in a time-dependent manner. CONCLUSIONS Prepubertal children with ADHD had normal height, weight, BMI, serum IGF-I and IGFBP-3 and thyroid functions. Methylphenidate treatment had no sustained effects on growth parameters, IGF-I and IGFBP-3 during the follow-up period of this study. However, it caused a mild decrease in total and free T4 which may warrant further monitoring.
