Transition from pediatric to adult care in patients with Turner syndrome in Italy: a consensus statement by the TRAMITI project.

PURPOSE: Transition from pediatric to adult care is associated with significant challenges in patients with Turner syndrome (TS). The objective of the TRansition Age Management In Turner syndrome in Italy (TRAMITI) project was to improve the care provided to patients with TS by harnessing the knowledge and expertise of various Italian centers through a Delphi-like consensus process. METHODS: A panel of 15 physicians and 1 psychologist discussed 4 key domains: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. RESULTS: A total of 41 consensus statements were drafted. The transition from pediatric to adult care is a critical period for patients with TS, necessitating tailored approaches and early disclosure of the diagnosis to promote self-reliance and healthcare autonomy. Fertility preservation and bone health strategies are recommended to mitigate long-term complications, and psychiatric evaluations are recommended to address the increased prevalence of anxiety and depression. The consensus also addresses the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS; regular screenings and interventions are advised to manage these conditions effectively. In addition, cardiac abnormalities, including aortic dissections, require regular monitoring and early surgical intervention if certain criteria are met. CONCLUSIONS: The TRAMITI consensus statement provides valuable insights and evidence-based recommendations to guide healthcare practitioners in delivering comprehensive and patient-centered care for patients with TS. By addressing the complex medical and psychosocial aspects of the condition, this consensus aims to enhance TS management and improve the overall well-being and long-term outcomes of these individuals.

The TRansition Age Management in Turner syndrome in Italy (TRAMITI) project aims to improve care for individuals with Turner Syndrome (TS) during their transition from pediatric to adult care. A team of 15 physicians and 1 psychologist collaborated to create a comprehensive set of 41 consensus statements, covering four key areas: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. The consensus statements highlight the importance of patient-centered care, early intervention and long-term monitoring. They emphasize a multidisciplinary approach to address the complex medical and psychosocial aspects of TS. During the critical transition period, tailored approaches and early disclosure of the diagnosis are recommended to promote self-reliance and healthcare autonomy. To mitigate long-term complications, the consensus addresses fertility preservation and bone health strategies. It also recommends psychological or psychiatric evaluations to tackle the increased prevalence of anxiety and depression in patients with TS. In addition, strategies for addressing the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS are proposed. Regular screenings and interventions are advised to effectively manage these conditions. Furthermore, cardiac abnormalities, including aortic dissections, require close monitoring and early surgical intervention if specific criteria are met. Overall, the TRAMITI consensus statement provides valuable insights and evidence-based recommendations. It offers guidance for healthcare practitioners in delivering comprehensive and patient-centered care for individuals with TS. By addressing both medical and psychosocial aspects, the consensus aims to enhance TS management and improve the well-being and long-term outcomes of those affected by this genetic disorder.

Influence of biochemical diagnosis of growth hormone deficiency on replacement therapy response and retesting results at adult height.

Isolated growth hormone deficiency (IGHD) is the most frequent endocrinological disorder in children with short stature, however the diagnosis is still controversial due to the scarcity of reliable diagnostic criteria and pre-treatment predictive factors of long term-response. To evaluate recombinant growth hormone (rGH) long-term response and retesting results in three different groups of children divided in accordance with the biochemical criteria of initial diagnosis. Height gain (∆HT) at adult height (AH) and retesting results were evaluated in 57 rGH treated children (M = 34, 59.6%) divided into 3 groups according to initial diagnosis: Group A (n = 25) with max GH peak at stimulation test < 8 µg/L, Group B (n = 19) between 8 and 10 µg/L and Group C (n = 13) with mean overnight GH < 3 µg/L (neurosecretory dysfunction, NSD). Retesting was carried out in all patients after at least one month off therapy upon reaching the AH. 40/57 (70.2%) patients were pre-pubertal at diagnosis and showed ∆HT of 1.37 ± 1.00 SDS, with no significant differences between groups (P = 0.08). Nonetheless, 46% patients in Group B showed ∆HT < 1SDS (vs 13% and 12% in Group A and C, respectively) and 25% children failed to reach mid-parental height (vs 6% and 0% in Group A and C, respectively). At AH attainment, IGHD was reconfirmed in 28% (7/25) and 10% (2/19) in Group A and B, respectively. A reduction of diagnostic cut-off at GH stimulation tests could better discriminate between "good" and "poor responders" and predict the persistence of IGHD through transition. Group C response and the predictive value of baseline IGF-I SDS bring back to light NSD: should we consider an underlying hypothalamic derangement when the clinical presentation is strongly consistent with IGHD but pharmacological stimulation test is normal?

Progressive bone impairment with age and pubertal development in neurofibromatosis type I.

Bone density impairment represents an established complication in adults with neurofibromatosis type 1, while few data exist in the pediatric population. Age- and gender-adjusted bone mass decreases with age and pubertal development, identifying childhood as the best time frame to introduce prevention strategies aiming at peak bone mass achievement. PURPOSE: The present study aims at evaluating bone mineral density (BMD) in a population of children with neurofibromatosis type I (NF-1), with particular focus on changes occurring during growth and pubertal development. METHODS: Bone metabolic markers and bone status [by dual-energy X-ray absorptiometry scans (DXA) of the total body and lumbar spine with morphometric analysis] were assessed in 50 children (33 males; mean age ± SD, 11.6 ± 4 years). Bone mineral apparent density (BMAD), trabecular bone score (TBS), and bone strain (BS) of the lumbar spine (LS) DXA were also obtained. RESULTS: In our cohort areal BMD (aBMD) Z-score was below the mean in 88% of the patients at LS (70% after correction for bone size) and in 86% considering total body (TB) DXA. However, aBMD Z-score was < - 2 in 12% after correction for bone size at LS and TB, respectively. Lumbar spine aBMD Z-score (r = - 0.54, P < 0.0001), LS BMAD Z-score (r = - 0.53, P < 0.0001), and TB Z-score (r = - 0.39, P = 0.005) showed a negative correlation with growth and pubertal development (P = 0.007, P = 0.02, P = 0.01, respectively), suggesting that patients failed to gain as much as expected for age. CONCLUSION: Bone density impairment becomes more evident with growth and pubertal development in NF-1 patients, thus identifying childhood as the best time frame to introduce prevention strategies aiming at peak bone mass achievement. TBS and BS, providing bone DXA qualitative information, could be useful during longitudinal follow-up for better characterizing bone impairment in these patients.

Long-term safety and efficacy of Omnitrope® in adults with growth hormone deficiency: Italian interim analysis of the PATRO Adults study.

PURPOSE: To report the long-term effectiveness and safety of the recombinant human growth hormone Omnitrope®, a somatropin biosimilar to Genotropin®, in Italian patients with growth hormone deficiency (GHD) enrolled in the PATRO Adults study. METHODS: The PATRO Adults study is an ongoing observational, longitudinal, non-interventional global post-marketing surveillance study, conducted in several European countries. The primary endpoint is long-term safety; secondary endpoints include the effectiveness of Omnitrope®, which was assessed using serum insulin-like growth factor-1 levels, body composition, bone mineral density and lipid levels. Here we report the data from the Italian patients enrolled in the study. RESULTS: Sixty-seven patients (mean age 50.4 years, 61.2% male) have been enrolled and have received a mean 45.4 ± 24.3 months of Omnitrope®. A total of 55.2% of patients were reported to have experienced adverse events (AEs), including arthralgia, myalgia, abdominal distension and hypoaesthesia, and 4.5% had adverse drug reactions. Fourteen serious AEs have been recorded; none of these are considered related to the study drug. The effectiveness of Omnitrope® was similar to other available somatropin preparations. CONCLUSIONS: This study confirms the effectiveness and safety of Omnitrope® in adult patients with GHD in Italy. However, due to the limited size of the study population, these results need to be further confirmed by the global PATRO Adults study.

Birmingham epidermolysis severity score and vitamin D status are associated with low BMD in children with epidermolysis bullosa.

Bone status impairment represents a complication of generalized forms of epidermolysis bullosa (EB); however, the prevalence and the main determinants of this event in localized forms remain poorly defined. Birmingham epidermolysis bullosa severity (BEBS) score and 25-hydroxyvitamin D levels are strongly associated with low bone mass, suggesting that vitamin D may play a potential beneficial role in bone health. Further longitudinal studies are needed in order to confirm this hypothesis. INTRODUCTION: Bone status impairment represents a complication of generalized forms of EB; thus, we aimed to estimate the prevalence of low bone mass, to examine mineralization differences in various EB subtypes and to identify the most important determinants of bone impairment in children with either generalized or localized EB. METHODS: An observational study of 20 children (11 males; mean age ± standard deviation, 11.7 ± 3.9 years) with EB was performed. Clinical history, physical examination, laboratory studies, X-ray of the left hand and wrist for bone age, and dual energy X-ray absorptiometry scans of the lumbar spine were obtained. Areal bone mineral density (aBMD Z-scores) and bone mineral apparent density were related to the BEBS score. RESULTS: Areal BMD Z-score (mean -1.82 ± 2.33, range, -7.6-1.7) was reduced (<-2 SD) in 8 patients (40%), whereas aBMD Z-score adjusted for bone age was low in 7 patients (35%). BEBS score and 25-hydroxyvitamin D serum levels were the most important elements associated with aBMD (P = 0.0001 and P = 0.016, respectively). A significant correlation between the aBMD Z-score and area of skin damage, insulin-like growth factor-1, C-reactive protein, and sodium serum levels was also found. CONCLUSIONS: Low aBMD can be considered a systemic complication of EB, primarily associated with BEBS score and 25-hydroxyvitamin D levels. Therefore, longitudinal evaluation of bone status is ongoing in these patients to define whether vitamin D supplementation would prevent, or at least reduce, bone status impairment.

Recurrence of hyperprolactinemia following dopamine agonist withdrawal and possible predictive factors of recurrence in prolactinomas.

BACKGROUND: The optimal duration of cabergoline (CAB) treatment of prolactinomas that minimizes recurrences is not well established. 2011 Endocrine Society Guidelines suggested that withdrawal may be safely undertaken after 2 years in patients achieving normoprolactinemia and tumor reduction. MATERIALS: We analyzed 74 patients (mean age = 46.9 ± 14.4, M/F = 19/55, macro/micro = 18/56) bearing a prolactinoma divided in 3 groups: group A (23) treated for 3 years, group B (23) for a period between 3 and 5 years, and group C (28) for a period >5 years. CAB therapy was interrupted according to Endocrine Society Guidelines. Prolactin (PRL) levels were measured 3, 6, 12 and 24 months after withdrawal. Recurrence was defined with PRL levels ≥30 ng/ml. RESULTS: Groups did not differ in pretreatment PRL levels (123.2 ± 112.1, 120.9 ± 123.8, 176.6 ± 154.0), pituitary deficit (4, 17, 17 %), mean CAB weekly dose (0.7 ± 0.4, 0.6 ± 0.3, 0.7 ± 0.4) and PRL levels before withdrawal (17.1 ± 19.6, 11.4 ± 8.8, 13.8 ± 13.5). Recurrence occurred within 12 months in 34 patients (45.9 %), without significant differences among groups. Neuroradiological evaluation showed a significantly higher presence of macroadenoma in group C (13, 17 and 39 %, respectively). Recurrence rate of hyperprolactinemia did not depend on sex, tumor size or CAB dose but it was significantly correlated with PRL levels at diagnosis and before withdrawal (p = 0.03). Finally, patients with pituitary deficit at diagnosis showed a significantly higher recurrence rate (p = 0.03). CONCLUSIONS: The study provides additional evidence that prolonging therapy for more than 3 years does not reduce recurrence rate. In particular, recurrence risk was similar in micro- and macroadenomas, and higher in patients with pituitary deficits at diagnosis.

Analysis of short- and long-term metabolic effects of growth hormone replacement therapy in adult patients with craniopharyngioma and non-functioning pituitary adenoma.

PURPOSE: Adult patients operated for craniopharyngioma develop more frequently GH deficiency (GHD) than patients operated for non-functioning pituitary adenoma (NFPA). The aim of the study was to compare both short- (1 year) and long-term (5 years) effects of rhGH in 38 GHD adult patients (19 operated for Craniopharyngioma (CP) and 19 for NFPA). METHODS: IGF-I levels, body composition (BF%), BMI, lipid profile and glucose homeostasis were evaluated in all patients. Pituitary MRI was performed at baseline and during follow-up, as needed. RESULTS: At baseline no difference between the two groups was observed, apart from a higher prevalence of diabetes insipidus in CP patients (79 vs 21%). After 12 months, IGF-I SDS normalized and BF% significantly decreased only in the NFPA group. During long-term treatment, decrease in BF% and improvement in lipid profile shown by reduction in total- and LDL-cholesterol were present in NFPA group only, while increase in insulin levels and HbA1c and decrease of QUICKI were observed in CP patients only. Accordingly, after long-term therapy, the prevalence of metabolic syndrome (MS) was significantly higher in CP than in NFPA group (37% in CP and in 5% in NFPA group; p < 0.05). CONCLUSION: The present data suggest that CP patients are less sensitive to the positive rhGH effects on lipid profile and BF% and more prone to insulin sensitivity worsening than NFPA patients, resulting in increased prevalence of MS in CP only.

Impact of IGF(CA)19 gene polymorphism on the metabolic response to GH therapy in adult GH-deficient patients.

OBJECTIVE: A polymorphism in the promoter region of the IGF1 gene has been linked to serum IGF1 levels, risk of diabetes, and cardiovascular diseases with conflicting results. The aim of this study was to investigate the impact of this polymorphism on the short-term (1 year, n=98) and long-term (5 years, n=50) metabolic response to recombinant human GH (rhGH) in GH-deficient (GHD) adults. DESIGN AND METHODS: Prospective study on GHD adults. Different genotypes were studied by microsatellite method. According to the most frequent 192 bp allele (19 cytosine-adenosine-repeats), subjects were divided into homozygous (19/19), heterozygous (19/X), and noncarriers (X/X). RESULTS: Basal characteristics of patients as well as their response to rhGH in terms of decrease in body fat percentage and increase in IGF1 levels were not different in the three genotype-groups. Conversely, after 1-year rhGH, a significant worsening of insulin sensitivity (i.e. increase in fasting glucose levels and homeostasis model assessment of insulin resistance) and a significant improvement in lipid profile (i.e. reduction in total cholesterol and LDL-cholesterol) were recorded only in homozygous subjects. In the long-term, insulin sensitivity was restored in all the patients, while a significant improvement in lipid profile was observed in homozygous and heterozygous subjects, but not in noncarrier subjects. No difference in rhGH dose among groups was recorded throughout the study. CONCLUSIONS: In GHD adults, the presence of the WT allele in the IGF1 gene promoter may enhance sensitivity to either negative or positive metabolic changes induced by rhGH.

Epicardial fat thickness significantly decreases after short-term growth hormone (GH) replacement therapy in adults with GH deficiency.

BACKGROUND AND AIM: Growth Hormone Deficiency (GHD) is characterized by increased visceral fat accumulation. Echocardiographic epicardial fat thickness is a new marker of visceral adiposity. Aim of the present study was to evaluate whether epicardial fat thickness can significantly change and therefore serve as a marker of visceral fat reduction after short-term rhGH replacement therapy in patients with adult-onset GHD. METHODS AND RESULTS: Echocardiographic epicardial fat thickness was measured in 18 patients (10 M, 8 F, age 48 ± 11.8 yrs, BMI 29 ± 5.9 kg/m(2)) with adult-onset GHD, at baseline and after 6 and 12 months of rhGH therapy and in 18 healthy matched controls, at baseline. Echocardiographic epicardial fat thickness, conventional anthropometric and metabolic parameters, body fat percentage and quality of life were also evaluated. Epicardial fat thickness in adult GHD patients was higher than in controls (9.8 ± 2.8 vs 8 ± 3 mm, p < 0.05). Epicardial fat thickness significantly decreased after 6-months of rhGH replacement therapy (from 9.8 ± 2.8 to 7.0 ± 2.3 mm, P < 0.01, i.e. -29% from baseline). After 12 months of rhGH replacement therapy, epicardial fat thickness showed a further significant decrease (from 7.0 ± 2.3 to 5.9 ± 3.1 mm, P < 0.01, i.e. -40% from baseline). No significant changes in BMI or waist circumference after 6 or 12 months of rhGH therapy were observed. CONCLUSIONS: Echocardiographic epicardial fat thickness may represent a valuable and easy marker of visceral fat and visceral fat changes during rhGH replacement treatment in patients with adult-onset growth hormone deficiency.
