- Recombinant human growth hormone (rhGH) has been in use for 30 years, and over that time its safety and efficacy in children and adults has been subject to considerable scrutiny. In 2001, a statement from the GH Research Society (GRS) concluded that 'for approved indications, GH is safe'; however, the statement highlighted a number of areas for on-going surveillance of long-term safety including; cancer risk, impact on glucose homeostasis and use of high dose pharmacological rhGH treatment. Over the intervening years, there have been a number of publications addressing the safety of rhGH with regard to mortality, cancer and cardiovascular risk and the need for longterm surveillance of the increasing number of adults who were treated with rhGH in childhood. Against this backdrop of interest in safety, the European Society of Paediatric Endocrinology (ESPE), the GRS and the Pediatric Endocrine Society (PES) convened a meeting to reappraise the safety of rhGH. The ouput of the meeting is a concise position statement.

- OBJECTIVE: Being born small for gestational age (SGA) is associated with insulin resistance, hypertension and increased cardiovascular morbidity/mortality in adulthood. Sympathetic nerve hyperactivity is a well-known risk factor for cardiovascular disease mortality and is proposed to link insulin resistance with hypertension. The objective of this study was to test the hypothesis that sympathetic nerve activity is altered in individuals born SGA. DESIGN: A cross-sectional, comparative study of 20 healthy adults (21-25 years old) born SGA (birth weight < -2SD score for healthy newborns) with normal and short stature, and 12 age, gender and body mass index matched individuals, born appropriate for gestational age (AGA) with normal stature. METHODS: Direct recordings of resting sympathetic nerve activity to the muscle vascular bed (MSA) were obtained from the peroneal nerve posterior to the fibular head. Heart rate, respiration and blood pressure were recorded during the microneurographic session. RESULTS: MSA was increased in both groups of young adults born SGA as compared to those born AGA (P < 0.05 and P < 0.005, respectively). In the combined study group MSA was inversely correlated to birth weight, length (r = -0.59, P < 0.001 and r = -0.69, P < 0.0005, respectively) and final adult height (r = -0.58; P < 0.001). CONCLUSIONS: Being born SGA and achieving a short final height is associated with increased sympathetic nerve traffic. We suggest that the increase in sympathetic nerve traffic in young adults born SGA with normal and short stature may be the link between low birth size, hypertension and cardiovascular morbidity later in life.

- The Growth Hormone Research Society (GRS) convened a Workshop in March 2019 to evaluate the diagnosis and therapy of short stature in children. Forty-six international experts participated at the invitation of GRS including clinicians, basic scientists, and representatives from regulatory agencies and the pharmaceutical industry. Following plenary presentations addressing the current diagnosis and therapy of short stature in children, breakout groups discussed questions produced in advance by the planning committee and reconvened to share the group reports. A writing team assembled one document that was subsequently discussed and revised by participants. Participants from regulatory agencies and pharmaceutical companies were not part of the writing process. Short stature is the most common reason for referral to the pediatric endocrinologist. History, physical examination, and auxology remain the most important methods for understanding the reasons for the short stature. While some long-standing topics of controversy continue to generate debate, including in whom, and how, to perform and interpret growth hormone stimulation tests, new research areas are changing the clinical landscape, such as the genetics of short stature, selection of patients for genetic testing, and interpretation of genetic tests in the clinical setting. What dose of growth hormone to start, how to adjust the dose, and how to identify and manage a suboptimal response are still topics to debate. Additional areas that are expected to transform the growth field include the development of long-acting growth hormone preparations and other new therapeutics and diagnostics that may increase adult height or aid in the diagnosis of growth hormone deficiency.

- Objective:To study two subsets of patients with GH deficiency (GHD) during the transition period: childhood onset GHD (CO-GHD) and patients who develop GHD during the transition phase (TO-GHD) before and after GH replacement.Patients and measurements:In 1340 GHD subjects from KIMS (Pfizer International Metabolic Database), CO (n=586) or TO (n=754), background characteristics, anthropometric measurements, IGF-1, lipids and quality of life (QoL) were evaluated at baseline and after 3 years of GH replacement.Results:Both groups responded similarly to GH treatment. Changes of clinical outcomes were mainly determined by their value at baseline. Onset of the disease in childhood or transition period did not appear to be a significant predictor of response in any of the clinical outcomes.Conclusions:Age at GHD diagnosis was a significant predictor for many outcomes at baseline, but disease onset did not appear as an independent predictor concerning changes after 3 years of GH treatment. The results suggest that GH replacement during the transition period should be considered independently of the onset of the deficiency.

Pituitary Neoplasm Nomenclature Workshop: Does Adenoma Stand the Test of Time?

Forskningsöversikt (refereegranskat)abstract
- The WHO Classification of Endocrine Tumours designates pituitary neoplasms as adenomas. A proposed nomenclature change to pituitary neuroendocrine tumors (PitNETs) has been met with concern by some stakeholder groups. The Pituitary Society coordinated the Pituitary Neoplasm Nomenclature (PANOMEN) workshop to address the topic. Experts in pituitary developmental biology, pathology, neurosurgery, endocrinology, and oncology, including representatives nominated by the Endocrine Society, European Society of Endocrinology, European Neuroendocrine Association, Growth Hormone Research Society, and International Society of Pituitary Surgeons. Clinical epidemiology, disease phenotype, management, and prognosis of pituitary adenomas differ from that of most NETs. The vast majority of pituitary adenomas are benign and do not adversely impact life expectancy. A nomenclature change to PitNET does not address the main challenge of prognostic prediction, assigns an uncertain malignancy designation to benign pituitary adenomas, and may adversely affect patients. Due to pandemic restrictions, the workshop was conducted virtually, with audiovisual lectures and written précis on each topic provided to all participants. Feedback was collated and summarized by Content Chairs and discussed during a virtual writing meeting moderated by Session Chairs, which yielded an evidence-based draft document sent to all participants for review and approval. There is not yet a case for adopting the PitNET nomenclature. The PANOMEN Workshop recommends that the term adenoma be retained and that the topic be revisited as new evidence on pituitary neoplasm biology emerges.

- With the number of long-term HSCT survivors steadily increasing, attention needs to be focused on the late complications and quality of life. We therefore analyzed the outcome of 101 pediatric patients (<18years old at the time of HSCT) transplanted for acute leukemia between 1981 and 2015 at Complexo Hospital de Clínicas, Federal University of Paraná, Brazil, and who survived at least two years after HSCT. The median follow-up was 5.9years (2.0-29.0); median age at follow-up was 17.5years (2.98-39.0). The 5-year cumulative incidence of relapse was 27.5% (95% CI 18.6%-36.4%). Two-year cumulative incidence of chronic GVHD was 21.8% (95% CI 13.7%-29.8%). Of the 101 patients, 72 patients (71.3%) presented with late effects. Those surviving longer after HSCT experienced more complications. Patients who received TBI-based regimen developed more late effects (P=.013) and more endocrinological complications (P=.024). Endocrinological complications were the most common late sequelae found in this study. For childhood survivors, quality of life was not influenced by age (at HSCT or at last visit), time from HSCT, gender, donor, or GVHD. For survivors that no longer were children, only age at last visit impacted financial domain measures, irrespective of gender, donor, or GVHD. The current study confirms the high burden late complications after pediatric HSCT have on the survivors and underlines the importance of extended follow-up.
