Malignancies in Prader-Willi Syndrome: Results From a Large International Cohort and Literature Review. J Clin Endocrinol Metab 2023; 108:e1720-e1730. [PMID: 37267430 PMCID: PMC10655548 DOI: 10.1210/clinem/dgad312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 04/25/2023] [Accepted: 05/26/2023] [Indexed: 06/04/2023]
Abstract
CONTEXT Prader-Willi syndrome (PWS) is a complex disorder combining hypothalamic dysfunction, neurodevelopmental delay, hypotonia, and hyperphagia with risk of obesity and its complications. PWS is caused by the loss of expression of the PWS critical region, a cluster of paternally expressed genes on chromosome 15q11.2-q13. As life expectancy of patients with PWS increases, age-related diseases like malignancies might pose a new threat to health. OBJECTIVE To investigate the prevalence and risk factors of malignancies in patients with PWS and to provide clinical recommendations for cancer screening. METHODS We included 706 patients with PWS (160 children, 546 adults). We retrospectively collected data from medical records on past or current malignancies, the type of malignancy, and risk factors for malignancy. Additionally, we searched the literature for information about the relationship between genes on chromosome 15q11.2-q13 and malignancies. RESULTS Seven adults (age range, 18-55 years) had been diagnosed with a malignancy (acute lymphoblastic leukemia, intracranial hemangiopericytoma, melanoma, stomach adenocarcinoma, biliary cancer, parotid adenocarcinoma, and colon cancer). All patients with a malignancy had a paternal 15q11-13 deletion. The literature review showed that several genes on chromosome 15q11.2-q13 are related to malignancies. CONCLUSION Malignancies are rare in patients with PWS. Therefore, screening for malignancies is only indicated when clinically relevant symptoms are present, such as unexplained weight loss, loss of appetite, symptoms suggestive of paraneoplastic syndrome, or localizing symptoms. Given the increased cancer risk associated with obesity, which is common in PWS, participation in national screening programs should be encouraged.

Clin Endocrinol (Oxf) 2023; 99:64-72. [PMID: 36905085 DOI: 10.1111/cen.14910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 02/15/2023] [Accepted: 03/07/2023] [Indexed: 03/12/2023]
Abstract
BACKGROUND Population studies suggest cancer morbidity may be different in Turner syndrome (TS) compared to the background female population. However, significant variability is observed in cancer associations likely due to heterogeneity in patient cohorts. We explored the prevalence and patterns of cancer amongst a cohort of women with TS attending a dedicated TS clinic. METHODS Retrospective analysis of the patient database was performed to identify TS women who developed cancer. Population data (available before 2015) from the National Cancer Registration and Analysis Service database were used for comparison. RESULTS Out of 156 TS women, median age of 32 (range 18-73) years, 9 (5.8%) had a recorded cancer diagnosis. Types of cancers were, bilateral gonadoblastoma, type 1 gastric neuroendocrine tumour (NET), appendiceal-NET, gastrointestinal stromal tumour, plasma cell dyscrasia, synovial sarcoma, cervical cancer, medulloblastoma and aplastic anaemia. Median age at cancer diagnosis was 35 (range 7-58) years and two were detected incidentally. Five women had 45,X karyotype, three received growth hormone treatment and all except one received oestrogen replacement therapy. The cancer prevalence of the background age-matched female population was 4.4%. CONCLUSIONS We confirm the previous observations that women with TS do not appear to be at overall increased risk of common malignancies. Our small cohort showed a spectrum of rare malignancies that are not typically associated with TS, except for a single patient with a gonadoblastoma. The slightly higher prevalence of cancer in our cohort might simply represent increased cancer prevalence in the background population, or might be related to small sample size and regular monitoring of these women due to TS per se.

Abstract
Liver impact of prolonged GH-treatment given to non-GH-deficient growing mice between the third and eighth week of life was evaluated in both sexes. Tissues were collected 6 h after last dose or four weeks later. Somatometric, biochemical, histological, immunohistochemical, RT-qPCR and immunoblotting determinations were performed. Five-week GH intermittent administration induced body weight gain and body and bone length increase, augmented organ weight, higher hepatocellular size and proliferation, and increased liver IGF1 gene expression. Phosphorylation of signaling mediators and expression of GH-induced proliferation-related genes was decreased in GH-treated mice liver 6h after last injection, reflecting active sensitization/desensitization cycles. In females, GH elicited EGFR expression, associated to higher EGF-induced STAT3/5 phosphorylation. Four weeks after treatment, increased organ weight concomitant to body weight gain was still observed, whereas hepatocyte enlargement reverted. However, basal signaling for critical mediators was lower in GH-treated animals and in male controls compared to female ones, suggesting signaling declination.

Abstract
Abstract
Purpose
At present, autologous platelet-derived therapies such as platelet-rich plasma is widely used in the clinic, but allogeneic and xenogeneic therapies are currently in the research stage, mainly due to their biocompatibility in vivo. Platelet lysates depleted of antigens such as blood cells are a potential solution for allogeneic or xenogeneic applications. Platelet lysates can successfully promote the growth and differentiation of xenogeneic cells in vitro, but in vivo data are not yet available. This study aims to evaluate whether porcine platelet lysate can effectively avoid inflammatory reaction in rabbit knee joint, and then treat cartilage defect and arthritis.
Methods
We developed porcine platelet lysates containing undetectable antigens such as blood cells and complement. For xenogeneic application, platelet lysate was injected into rabbit knee joints to observe joint responses. To examine cartilage repair, osteochondral defects were created in rabbit knee joints. Rabbits were sacrificed three months after treatment with platelet lysate to observe cartilage regeneration and arthritis.
Results
The tissue sections in the rabbit knee joints showed no inflammatory reaction. Furthermore, the injection of platelet lysate was found to effectively inhibit the formation of cartilage arthritis in rabbit knee joints.
Conclusion
Our experimental results show that xenogeneic platelet lysate is a safe and effective method in the treatment of arthritis, which can be used as a research basis for future medical applications. The use of xenogeneic platelet lysate for regenerative therapy in vivo is feasible.

Abstract
Growth hormone (GH) and downstream insulin-like growth factor 1 (IGF1) signaling mediate growth and metabolism. GH deficiency causes short stature or dwarfism, and excess GH causes acromegaly. Although the association of GH/IGF1 signaling with liver diseases has been suggested previously, current studies are controversial and the functional roles of GH/IGF1 signaling are still undefined. GH supplementation therapy showed promising therapeutic effects in some patients, such as non-alcoholic fatty liver disease, but inhibition of GH signaling may be beneficial for other liver diseases, such as hepatocellular carcinoma. The functional roles of GH/IGF1 signaling and the effects of agonists/antagonists targeting this signaling may differ depending on the liver injury or animal models. This review summarizes current controversial studies of GH/IGF1 signaling in liver diseases and discusses therapeutic potentials of GH therapy.

Abstract
Growth hormone and its mediator insulin‐like growth factor‐1 exert their effect on different organs and control various physiologic metabolic processes. Adult growth hormone deficiency (AGHD) presents with one or more components of metabolic syndrome and can be associated with nonalcoholic fatty liver disease (NAFLD). AGHD is present in spectrum of hypothalamic/pituitary disorders as well as cranial radiation of brain tumors and often remains underdiagnosed or untreated due to its nonspecific symptoms, relatively difficult diagnosis in some clinical scenarios, and various barriers to treatment. NAFLD usually develops soon after diagnosis of AGHD and might progress rapidly to nonalcoholic steatohepatitis (NASH) with advanced fibrosis, eventually requiring liver transplantation. A timely initiation of growth hormone replacement therapy might be important, although studies so far have demonstrated controversial results on NAFLD, primarily due to small sample size and different diagnostic methods of NAFLD. Increased awareness of the association between AGHD and NAFLD would facilitate early diagnosis of NAFLD and NASH if present. Therefore, a multidisciplinary approach involving hepatology and endocrinology should become a standard of care for these patients.

Abstract
Serum insulin-like growth factor-1 (IGF-I) and IGF binding protein-3 (IGFBP-3) levels can be used to monitor the safety of recombinant human growth hormone (rhGH) therapy. In this study, we evaluated the changes in serum IGF-I and IGFBP-3 levels during rhGH therapy as a marker of height outcome in prepubertal children. Totally, 705 prepubertal children with short stature were enrolled from the LG Growth Study Database. Data for three groups of subjects were obtained as follows: Idiopathic GH deficiency (IGHD; n = 486); idiopathic short stature (n = 66); small for gestational age (n = 153). Serum IGF-I and IGFBP-3 levels at the baseline and after the 1st and 2nd year of rhGH therapy, as well as the Δheight standard deviation score (SDS), were obtained. Δheight SDS after the 1st and 2nd year of rhGH therapy had notably increased compared to that at the baseline for all three groups. IGF-I and IGFBP-3 levels in all three groups were significantly increased compared to those at the baseline (p <0.001). Δheight SDS was positively correlated with ΔIGF-1 SDS after the 1st year of therapy, ΔIGFBP-3 SDS after the 2nd year of therapy in the IGHD group, and ΔIGF-I SDS and ΔIGFBP-3 SDS after the 2nd year of therapy (p < 0.05), regardless of whether the height at the baseline was a covariate. The increase in IGF-I and IGFBP-3 levels during rhGH therapy was related to the growth response in children with IGHD. Therefore, it may be valuable to measure the change in serum IGF-I and IGFBP-3 levels, especially the latter, during rhGH treatment to predict the growth response upon long-term treatment.

Abstract
Epidermal growth factor receptor (EGFR) signaling has a central role in the regenerative response of the liver upon injury and is involved in cellular transformation linked to chronic damage. Hepatic EGFR expression, trafficking, and signaling are regulated by growth hormone (GH). Chronically elevated GH levels are associated with liver cancer development and progression in mice. Studies in different in vivo experimental models indicate that EGF and GH mutually crossregulate in a complex manner. Several factors, such as the extent of exposure to supraphysiological GH levels and the pattern of GH administration, are important variables to be considered in exploring the interplay between the two hormones in connection with the progression of hepatic tumors.

Abstract
Assessment and management of children with growth failure has improved greatly over recent years. However, there remains a strong potential for further improvements by using novel digital techniques. A panel of experts discussed developments in digitalization of a number of important tools used by pediatric endocrinologists at the third 360° European Meeting on Growth and Endocrine Disorders, funded by Merck KGaA, Germany, and this review is based on those discussions. It was reported that electronic monitoring and new algorithms have been devised that are providing more sensitive referral for short stature. In addition, computer programs have improved ways in which diagnoses are coded for use by various groups including healthcare providers and government health systems. Innovative cranial imaging techniques have been devised that are considered safer than using gadolinium contrast agents and are also more sensitive and accurate. Deep-learning neural networks are changing the way that bone age and bone health are assessed, which are more objective than standard methodologies. Models for prediction of growth response to growth hormone (GH) treatment are being improved by applying novel artificial intelligence methods that can identify non-linear and linear factors that relate to response, providing more accurate predictions. Determination and interpretation of insulin-like growth factor-1 (IGF-1) levels are becoming more standardized and consistent, for evaluation across different patient groups, and computer-learning models indicate that baseline IGF-1 standard deviation score is among the most important indicators of GH therapy response. While physicians involved in child growth and treatment of disorders resulting in growth failure need to be aware of, and keep abreast of, these latest developments, treatment decisions and management should continue to be based on clinical decisions. New digital technologies and advancements in the field should be aimed at improving clinical decisions, making greater standardization of assessment and facilitating patient-centered approaches.

Abstract
Fibroma of tendon sheath (FTS) is an uncommon mass that arises from the tendon sheath of extremities. The tumor typically affects adults between ages 20 and 50 years with a predominance in males. To date, growth hormone (GH) treatment is safe for children with Turner syndrome without risk factors and is accepted worldwide. This article reports the case of a nine-year-old female patient with Turner syndrome and FTS during GH treatment. She had been treated with daily subcutaneous GH to improve growth failure with a mean dose of 0.28 mg/kg/week and the level of insulin-like growth factor-1 was within the normal range. During the follow-up period, she complained about a mass in her hand, subsequently diagnosed as FTS. This report illustrates the clinical impact of Turner syndrome and GH treatments on the occurrence of this tumor through literature reviews. Further studies are needed to highlight the association between FTS and GH treatment, especially in Turner syndrome.

Squamous Cell Carcinoma of the Tongue in Young Patients: A Case Series and Literature Review. J Oral Maxillofac Surg 2020; 79:1270-1286. [PMID: 33450194 DOI: 10.1016/j.joms.2020.12.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 12/10/2020] [Accepted: 12/11/2020] [Indexed: 12/16/2022]
Abstract
PURPOSE The purpose of this study was to describe 3 cases of tongue cancer in patients less than 21 years of age. Secondarily, a literature review was performed to examine disease presentation, risk factors, prognosis, and treatment strategies for young persons with tongue cancer. METHODS The authors presented 3 cases of childhood tongue cancer between 2009 and 2020 at the University of Michigan Department of Oral and Maxillofacial Surgery (Ann Arbor, MI). An electronic literature review was conducted via PubMed, Embase, Web of Science, and MLibrary. RESULTS Including the present case series, 64 studies reporting 108 cases were identified. Age at presentation ranged from newborn to 20 years, with a mean age of 14.5 years. The majority of patients were female (52.2%); 68.1% of patients presented with T1 or T2 disease. Nodal metastases were seen in 56.1% of patients. The most commonly identified predisposing factors included Fanconi anemia (13.9%), bone marrow transplant (9.3%), tobacco use (6.5%), and xeroderma pigmentosum (4.6%). Most patients received surgery alone (37.5%), followed by surgery with adjuvant radiation (33.8%); 60.6% underwent neck dissection. Overall survival was 60.3% at 1 year and 43.6% at 5 years. CONCLUSIONS Oral tongue cancer in the young is a rare disease with poorly understood etiology. There is a need for oncologists and maxillofacial surgeons to collaborate in the study of genetic, social, environmental, and medical risk factors contributing to the disease. All patients should undergo high-throughput genetic sequencing to expand our understanding of the disease process and allow for targeted treatment strategies.

Abstract
This article reports a case of a 7-year-old girl with Turner syndrome, treated with growth hormone (GH), who developed ovarian dysgerminoma. The patient karyotype was mosaic for chromosome Xq deletion: 46,X,del(X)(q22)/45,X. No Y chromosome sequences were present. Molecular studies revealed the presence of a driving mutation in exon 17 of the KIT gene in the neoplastic tissue, as well as Sonic-hedgehog (SHH) pathway activation at the protein level. The patient responded well to chemotherapy and remained in complete remission. This is the first case of dysgerminoma in a Turner syndrome patient with such oncogenic pathway.

Abstract
Emerging evidence links the growth hormone (GH)-insulin-like growth factor-1 (IGF1) endocrine axis to cancer development. While this putative correlation is of major translational relevance, most clinical and epidemiological reports to date found no causal linkage between GH therapy and enhanced cancer risk. Thus, it is generally agreed that GH therapy constitutes a safe pharmacological intervention. The present review focuses on a number of issues in the area of GH-IGF1 action in cancer development. Emphasis is given to the idea that GH and IGF1 do not conform to the definition of oncogenic factors. Specifically, these hormones, even at high pharmacological doses, are unable to induce malignant transformation. However, the GH-IGF1 axis is capable of 'pushing' already transformed cells through the various phases of the cell cycle. Viral and cellular oncogenes require an intact IGF1 signaling pathway in order to elicit transformation; in other words, oncogenic agents adopt the IGF1 pathway. This universal mechanism of action of oncogenes has broad implications in oncology. Our review provides an in-depth analysis of the interplay between the GH-IGF1 axis and cancer genes, including tumor suppressors p53 and BRCA1. Finally, the safety of GH therapy in both children and adults needs further long-term follow-up studies.

Gutiérrez M. Activating mutations of STAT3: Impact on human growth. Mol Cell Endocrinol 2020; 518:110979.

Abstract
The signal transducer and activator of transcription (STAT) 3 is the most ubiquitous member of the STAT family and fulfills fundamental functions in immune and non-immune cells. Mutations in the STAT3 gene lead to different human diseases. Germline STAT3 activating or gain-of-function (GOF) mutations result in early-onset multiorgan autoimmunity, lymphoproliferation, recurrent infections and short stature. Since the first description of the disease, the clinical manifestations of STAT3 GOF mutations have expanded considerably. However, due to the complexity of immunological characteristics in patients carrying STAT3 GOF mutations, most of attention was focused on the immune alterations. This review summarizes current knowledge on STAT3 GOF mutations with special focus on the growth defects, since short stature is a predominant feature in this condition. Underlying mechanisms of STAT3 GOF disease are still poorly understood, and potential effects of STAT3 GOF mutations on the growth hormone signaling pathway are unclear. Functional studies of STAT3 GOF mutations and the broadening of clinical growth-related data in these patients are necessary to better delineate implications of STAT3 GOF mutations on growth.

Int J Endocrinol Metab 2020; 18:e107292. [PMID: 33613679 PMCID: PMC7887459 DOI: 10.5812/ijem.107292] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 09/14/2020] [Accepted: 09/23/2020] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Noonan syndrome is an autosomal dominant condition with an incidence of 1:1000 to 1:2500. The disorder is associated with distinct dysmorphic features, cardiac anomalies, developmental delay and delayed puberty. Short stature is a recognised feature of Noonan syndrome. OBJECTIVES The aim of this study is to assess the effect of growth hormone treatment in patients with Noonan syndrome. METHODS Retrospective data was collected from patients with Noonan syndrome treated with growth hormone. The results were analysed with variables expressed as mean values and standard deviation scores. RESULTS Twelve Noonan syndrome patients (M: F = 10:2) treated with growth hormone were identified. The mean age of starting growth hormone was 8 years, with baseline height standard deviation score of -2.96 (range: -1.64 to -5.54). The height standard deviation score significantly improved to -2.50 (P = 0.0035) and then -2.22 (P = 0.0025), following one and two years of treatment, respectively. The average height velocity for the patients prior to starting treatment was 5.16cm/year (range: 2.4 - 8.2 cm/year), which significantly improved to 7.76cm/year (ranging from 4.1 to 12.8 cm/year) after one year of growth hormone treatment (P = 0.020) and to 6.51cm/year at the end of two years. CONCLUSIONS Our study has shown that growth hormone treatment significantly improves the height standard deviation score of patients with Noonan syndrome over a two-year course of growth hormone therapy without any side effects. Further research is required to analyse the long-term effect of growth hormone therapy in patients with Noonan syndrome, including the impact on final adult height.

Abstract
Various therapeutic approaches, for example, in case of trauma or cancer require the transplantation of autologous tissue. Depending on the size and the origin of the harvested tissue, these therapies can lead to iatrogenic complications and donor-site morbidities. In future, these side effects could be avoided by transplanting artificially generated tissue consisting of different cell types and matrix components derived from the host body. Tissue that is grown in the patient could be advantageous compared with the more simply structured in vitro-grown alternatives. To overcome the limitations of graft vascularization, the arteriovenous (AV) loop technique has been established for different tissues in the last years and was adapted for lymphatic tissue engineering in the present study. We utilized the AV loop technique to grow human lymphatic vasculature in vivo in the Rowett nude (RNU) rat. A combination of human lymphatic endothelial cells (LECs) and bone marrow-derived mesenchymal stem cells was implanted in a fibrin matrix surrounding the AV loop. After 2 or 4 weeks of implantation, the animals were perfused and the tissue was harvested. It could be demonstrated by immunohistochemistry for human LYVE1, human CD31, and murine podoplanin that the implanted cells formed human lymphatic vasculature in the AV loop chamber. Beside development of murine podoplanin-positive vasculature in the AV loop tissue, vasculature positive for human marker proteins developed in comparable numbers. This suggests that implanted LECs are able to improve the lymphatic vascularization of the newly engineered tissue. Thus, we were able to establish an in vivo tissue engineering method to generate lymphatic vascularized soft tissue. An axially vascularized transplantable lymphatic vessel network was engineered without requiring advanced cell culture equipment, rendering the lymphatic AV loop highly suitable for applied regenerative medicine. Impact statement Various surgical procedures require the transplantation of autologous harvested tissue, for example, the vascularized lymph node transfer for the treatment of lymphedema. Tissue-engineered transplants could be used instead of autologous transplants and thereby help to reduce the side effects of those therapies. However, in vitro tissue engineering of large constructs requires a lot of know-how as well as advanced cell culture equipment, which might not be accessible in every hospital. In vivo tissue engineering approaches like the presented technique for the generation of transplantable networks of lymphatic vasculature could serve as an alternative for in vitro tissue engineering approaches in clinical settings.

New insights into the protection of growth hormone in cisplatin-induced nephrotoxicity: The impact of IGF-1 on the Keap1-Nrf2/HO-1 signaling. Life Sci 2020; 253:117581. [PMID: 32209424 DOI: 10.1016/j.lfs.2020.117581] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Revised: 03/17/2020] [Accepted: 03/19/2020] [Indexed: 12/30/2022]
Abstract
AIMS Cisplatin (CDDP) is an effective antineoplastic agent, however, its serious nephrotoxicity limits therapeutic use. Human growth hormone (hGH) has proved antioxidant and anti-inflammatory activities. The present study aimed to investigate the nephroprotective effects of hGH against CDDP-induced nephrotoxicity and the mechanisms underlying this nephroprotection. MAIN METHODS Male albino rats injected with CDDP (7 mg/kg) and nephrotoxicity indices, oxidative stress and inflammatory biomarkers (high mobility group box protein-1 (HMGB-1), soluble epoxide hydrolase (sEH), and nuclear factor-kappa B (NF-κB)) were assessed. Also, insulin-like growth factor-1 (IGF-1) and Nuclear factor-erythroid-2 (Nrf2)/heme oxygenase-1 (HO-1) pathway were assessed. KEY FINDINGS hGH (1 mg/kg) improved kidney function and antioxidant systems and showed intact renal tubular epithelium. Cisplatin upregulated the HMGB-1/NF-κB and downregulated Nrf2/HO-1 pathways which were reversed by hGH and aligned with increased renal IGF-1 expression. Also, IGF-1/sEH crosstalk might be involved in hGH nephroprotection. Moreover, hGH downregulated HSP70 and caspase-3 expressions. SIGNIFICANCE these results concluded that hGH can attenuate the inflammation and oxidative stress attained by CDDP probably through inhibition of Nrf2/HO-1 pathway. We also suggested that Keap1/Nrf2-mediated upregulation of the antioxidant HO-1 might inhibit HMGB-1/NF-κB signaling and thus provide the principal protection mechanism offered by hGH against CDDP-induced kidney injury.

Abstract
Covid19 is a worldwide pandemic challenge that started in Wuhan, China and spread to almost all countries on the planet within a few months. The causative virus was found to be highly contagious and, until now, considerably difficult to contain. A look at the epidemiological distribution of the disease over the planet has raised a number of questions whose answers could help us understand the behavior of the virus and consequently leads us to possible means of limitation of its spread or even flattening of the curve of morbidity and mortality. After the third decade of life, there is a progressive decline of growth hormone (GH) secretion by approximately 15% for every decade of adult life. The data from highly affected countries suggest a more aggressive course in the elderly, a double-time affection of males more than females, and the vulnerability of some risk groups of patients. Our observation is that GH deficiency is a common factor in all vulnerable patient groups. We think that there is a need for studying the role of growth hormone in the unique epidemiological pattern of Covid-19 so that it might help in the early detection and management of the high-risk groups as appropriate.

Abstract
Hypopituitarism includes all clinical conditions that result in partial or complete failure of the anterior and posterior lobe of the pituitary gland’s ability to secrete hormones. The aim of management is usually to replace the target-hormone of hypothalamo-pituitary-endocrine gland axis with the exceptions of secondary hypogonadism when fertility is required, and growth hormone deficiency (GHD), and to safely minimise both symptoms and clinical signs. Adrenocorticotropic hormone deficiency replacement is best performed with the immediate-release oral glucocorticoid hydrocortisone (HC) in 2–3 divided doses. However, novel once-daily modified-release HC targets a more physiological exposure of glucocorticoids. GHD is treated currently with daily subcutaneous GH, but current research is focusing on the development of once-weekly administration of recombinant GH. Hypogonadism is targeted with testosterone replacement in men and on estrogen replacement therapy in women; when fertility is wanted, replacement targets secondary or tertiary levels of hormonal settings. Thyroid-stimulating hormone replacement therapy follows the rules of primary thyroid gland failure with L-thyroxine replacement. Central diabetes insipidus is nowadays replaced by desmopressin. Certain clinical scenarios may have to be promptly managed to avoid short-term or long-term sequelae such as pregnancy in patients with hypopituitarism, pituitary apoplexy, adrenal crisis, and pituitary metastases.
