Introduction: Growth hormone deficiency (GHD) may be associated with subtle cardiovascular abnormalities, reversible upon starting GH treatment. Data on vascular morphology and function in GHD children are scanty and inconclusive. The aim of our study was to evaluate the effects of GHD and GH treatment on endothelial function and intima-media thickness (IMT) in children and adolescents.
Methods: We enrolled 24 children with GHD (10.85 ± 2.71 years) and 24 age-, sex-, and BMI-matched controls. We evaluated anthropometry, lipid profile, asymmetric dimethylarginine (ADMA), brachial flow-mediated dilatation (FMD), and IMT of common (cIMT) and internal (iIMT) carotid artery at study entry in all subjects and after 12 months of treatment in GHD children.
Results: At baseline GHD, children had higher total cholesterol (163.17 ± 18.66 vs. 149.83 ± 20.68 mg/dL, p = 0.03), LDL cholesterol (91.18 ± 20.41 vs. 77.08 ± 19.73 mg/dL, p = 0.019), atherogenic index (AI) (2.94 ± 0.71 vs. 2.56 ± 0.4, p = 0.028), and ADMA (215.87 ± 109.15 vs. 164.10 ± 49.15 ng/mL, p < 0.001), compared to controls. GHD patients also exhibited increased higher waist-to-height ratio (WHtR) compared to controls (0.48 ± 0.05 vs. 0.45 ± 0.02 cm, p = 0.03). GH therapy resulted in a decrease in WHtR (0.44 ± 0.03 cm, p = 0.001), total (151.60 ± 15.23 mg/dL, p = 0.001) and LDL cholesterol (69.94 ± 14.40 mg/dL, p < 0.0001), AI (2.28 ± 0.35, p = 0.001), and ADMA (148.47 ± 102.43 ng/mL, p < 0.0001). GHD showed lower baseline FMD than controls (8.75 ± 2.44 vs. 11.85 ± 5.98%, p = 0.001), which improved after 1-year GH treatment (10.60 ± 1.69%, p = 0.001). Baseline cIMT and iIMT were comparable between the two groups, but slightly reduced in GHD patients after treatment.
Conclusion: GHD children may exhibit endothelial dysfunction in addition to other early atherosclerotic markers like visceral adiposity, and altered lipids, which can be restored by GH treatment.

: the aim of the current cross-sectional study is to explore and compare the emotional and behavioural conditions of children and adolescents with short stature (i.e., familial short stature and constitutional delay of growth), idiopathic growth hormone deficiency (GHD), and normal height.

Before 1985, growth hormone (GH) was extracted from human pituitaries, and its therapeutic use was limited to children with severe GH deficiency (GHD). The availability of an unlimited amount of recombinant GH (rhGH) allowed for investigating the efficacy of its therapeutic use in a number of conditions other than GHD. Nowadays, patients with Turner syndrome, deficiency, Noonan syndrome, Prader-Willi syndrome, idiopathic short stature, chronic kidney disease, and children born small for gestational age can be treated with rhGH in order to improve adult height.

Objective: In boys during puberty who were undergoing recombinant human growth hormone (rhGH) treatment, we compared the therapeutic efficacy on growth, and any adverse reactions, of co-therapy with either letrozole or gonadotropin-releasing hormone analog (GnRHa).
Methods: Fifty-six pubertal growth hormone deficiency (GHD) boys were studied, they were treated with the combination of letrozole and rhGH (letrozole group, n = 28) or the combination of GnRHa and rhGH (GnRHa group, n = 28) for at least one year. Eighteen patients in the letrozole group and seventeen patients in the GnRHa group attained final adult height (FAH).

Objectives: This study aimed to assess differences in insulin-like growth factor 1 (IGF-1) levels following the transition from somatropin to lonapegsomatropin in patients with pediatric growth hormone deficiency (GHD). Secondary objectives included the evaluation of dose titrations based on IGF-1 levels, changes in annualized height velocity (AHV) and body mass index (BMI), and assessing reported adverse effects associated with lonapegsomatropin therapy.
Methods: A single-center, retrospective review was conducted including patients diagnosed with pediatric GHD initially treated with somatropin who transitioned to lonapegsomatropin between January 1, 2022, and December 31, 2023.

Background: Pediatric growth hormone deficiency (GHD) is a disease resulting from the impaired growth hormone-insulin-like growth factor-1 (GH-IGF-1) axis, but the effects of GHD on children's behavior and brain microstructural structure alterations have not yet been fully clarified. We aimed to investigate the quantitative profiles of gray matter and white matter in pediatric GHD using synthetic magnetic resonance imaging (MRI).
Methods: The data of 50 children with GHD and 50 typically developing (TD) children were prospectively collected.
