A 12.5-year-old Italian girl was referred to our institute for progressive growth failure from the age of 6 years, with a height of 128.2 cm ( - 3.37 SDS) and a bone age of 9 years. Endocrinological evaluation revealed a partial growth hormone deficiency (GHD) and GH therapy was started at a dosage of 0.25 mg/kg/week. During the first 3 years, she showed an increase in growth rate and experienced pubertal development onset. Then a poor growth rate (2 cm/year 0.43 SDS) was observed, notwithstanding an increase in GH dosage (0.35 mg/kg/ week) and good compliance. We found a positive anti-GH antibody titre (1:1850, cutoff 1/100), confirmed 6 months later (1:2035); the antibodies had low binding capacity (0.63 μg/mL) and were only partially capable of inhibiting the GH effect. However, GH treatment was discontinued, and after 3 months the antibody titre decreased (1:950). In conclusion, we suggest evaluation of anti-GH antibodies in GH-treated idiopathic GHD children in whom growth response decreases after some years of therapy.

Background: To assess the prevalence of femicides in Italy over the last three years and the potential long lasting effects of these traumatic events for the children of a woman who dies a violent death. Methods: The data used in this study come from an internet search for the number of femicides occurring in Italy between 1st January, 2012 and 31st October, 2014. Results: The total number of femicides was 319; the average age of murdered women was 47.50∈±∈19.26. Cold arms in the form of sharp object -mostly knives- have caused the death of 102/319 women; firearms were used in 87/319 cases; asphyxiation was the chosen method in 52/319 cases. About the place where the femicides occurred, 209/319 were committed inside the victim's house. Children of women who died a violent death were 417 with a total of 180 minors in less than three years. A total of 52/417 children were witness to the killing and, among these 30/52 were minors; in 18/417 cases, children were murdered together with their mother and among these 9/18 were minors. Conclusions: Long-term studies are needed to ascertain what happens to these children, to understand what are the most appropriate psychological treatments, the best decisions about the contact with their father and the best placement for these children. © 2015 Ferrara et al.

It is a common knowledge that GH exhibits a large number of metabolic effects, involving lipid and glucose homeostasis. The aim of the study was to investigate the effect of one year GH therapy on metabolic parameters and adipokines in GH deficient (GHD) children. Sixteen prepubertal children (11 M and 5 F) with complete GHD (age range: 3.4-14.7 years) and 20 (13 M and 7 F) age and sex-matched healthy children (age range: 4.6-12.3 years) were studied. Blood was collected from patients before starting GH therapy (0.025 mg/kg/day) and one year later, and from healthy children to measure adiponectin, leptin, osteoprotegerin, resistin, interleukin (IL)-6, tumor necrosis factor (TNF)-α levels, and other glucose and lipid metabolism parameters. Adiponectin and resistin levels were significantly higher (49 980 ng/ml vs. 14 790 ng/ml and 11.0 pg/ml vs. 6.3, respectively) in GHD children before GH therapy than in controls. Serum IGF-I levels (p=0.0001) and height SDS (p<0.0001) significantly increased after 12 months' of GH therapy. There was a loss of body fat reflected by a significant decline in tricep (p=0.0003) and subscapular skinfold thickness SDS (p=0.0023). After 12 months, there was a significant rise in insulin (p=0.0052) and leptin levels (p=0.0048) and a significant decrease in resistin (p=0.0312) and TNF-α (p=0.0137). We observed that lipid and glucose metabolisms are only slightly affected in GHD children. Growth hormone replacement therapy affects some factors, such as leptin, resistin and fat mass, suggesting that also in children, GH treatment has a role in the regulation of factors secreted by adipose tissue. © Georg Thieme Verlag KG Stuttgart New York.

Children with Down syndrome (DS) have increased susceptibility to infections and a high frequency of leukemia and autoimmune disorders, suggesting that immunodeficiency and immune dysfunction are integral parts of the syndrome. A reduction in B-cell numbers has been reported, associated with moderate immunodeficiency and normal immunoglobulin levels. Here, we compared B-cell populations of 19 children with DS with those in healthy age-matched controls. We found that all steps of peripheral B-cell development are altered in DS, with a more severe defect during the later stages of B-cell development. Transitional and mature-naïve B-cell numbers are reduced by 50% whereas switched memory B cells represent 10-15% of the numbers in age-matched controls. Serum IgM levels were slightly reduced, but all other immunoglobulin isotypes were in the normal range. The frequency of switched memory B cells specific for vaccine antigens was significantly lower in affected children than in their equivalently vaccinated siblings. In vitro switched memory B cells of patients with DS have an increased ability to differentiate into antibody-forming cells in response to TLR9 signals. Tailored vaccination schedules increasing the number of switched memory B cells may improve protection and reduce the risk of death from infection in DS. © 2014 The Authors.

Metabolic Syndrome and Related Disorders | Year: 2014

Background: An increased relative risk of diabetes, ischemic heart disease, atherosclerosis, and hypertension have been reported in Turner syndrome (TS) patients. No data are currently available on the prevalence of metabolic syndrome in TS subjects. We evaluated the frequency of metabolic syndrome in obese and nonobese patients with TS. Patients and Methods: We evaluated 85 TS patients (27.05±11.17 years). Obesity was defined as standard deviation score body mass index (SDS-BMI) ≥2 or BMI ≥30 kg/m2 in adult patients. We classified metabolic syndrome according to the International Diabetes Federation (IDF). Hepatic ultrasound was performed in all girls. Results: The prevalence of metabolic syndrome was 4.7% (12.5% obese and 4.3% nonobese, P=0.16) and associated with visceral adiposity (P=0.008). Abnormalities in glucose metabolism and hypertension were not associated with genetic or therapeutic factors. The karyotype 45,X was associated with atherogenic profile. Pathological waist circumference was more frequent in girls treated with estro-progestin (P=0.03). Evidence of fatty liver was associated with metabolic syndrome (P=0.03) and insulin resistance (P=0.05). Elevated liver enzymes were found in 15 subjects and were not related to treatment or ultrasound abnormalities. Conclusions: Prevalence of each component of metabolic syndrome in TS patients is partially influenced by genetic makeup and treatment. Hepatosteatosis was associated with metabolic syndrome and insulin resistance, but not to elevated liver enzymes. © 2014, Mary Ann Liebert, Inc.
