Clinical lessons learned in constitutional hypopituitarism from two decades of experience in a large international cohort. Clin Endocrinol (Oxf) 2021; 94:277-289. [PMID: 33098107 DOI: 10.1111/cen.14355] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Revised: 09/04/2020] [Accepted: 09/08/2020] [Indexed: 01/05/2023]
Abstract
CONTEXT The international GENHYPOPIT network collects phenotypical data and screens genetic causes of non-acquired hypopituitarism. AIMS To describe main phenotype patterns and their evolution through life. DESIGN Patients were screened according to their phenotype for coding sequence variations in 8 genes: HESX1, LHX3, LHX4, PROP1, POU1F1, TBX19, OTX2 and PROKR2. RESULTS Among 1213 patients (1143 index cases), the age of diagnosis of hypopituitarism was congenital (24%), in childhood (28%), at puberty (32%), in adulthood (7.2%) or not available (8.8%). Noteworthy, pituitary hormonal deficiencies kept on evolving during adulthood in 49 of patients. Growth Hormone deficiency (GHD) affected 85.8% of patients and was often the first diagnosed deficiency. AdrenoCorticoTropic Hormone deficiency rarely preceded GHD, but usually followed it by over 10 years. Pituitary Magnetic Resonance Imaging (MRI) abnormalities were common (79.7%), with 39.4% pituitary stalk interruption syndrome (PSIS). The most frequently associated extrapituitary malformations were ophthalmological abnormalities (16.1%). Prevalence of identified mutations was 7.3% of index cases (84/1143) and 29.5% in familial cases (n = 146). Genetic analysis in 449 patients without extrapituitary phenotype revealed 36 PROP1, 2 POU1F1 and 17 TBX19 mutations. CONCLUSION This large international cohort highlights atypical phenotypic presentation of constitutional hypopituitarism, such as post pubertal presentation or adult progression of hormonal deficiencies. These results justify long-term follow-up, and the need for systematic evaluation of associated abnormalities. Genetic defects were rarely identified, mainly PROP1 mutations in pure endocrine phenotypes.

Abstract
GH deficiency (GHD) in adult patients is a complex condition, mainly due to organic lesion of hypothalamic-pituitary region and often associated with multiple pituitary hormone deficiencies (MPHD). The relationships between the GH/IGF-I system and other hypothalamic-pituitary axes are complicated and not yet fully clarified. Many reports have shown a bidirectional interplay both at a central and at a peripheral level. Signs and symptoms of other pituitary deficiencies often overlap and confuse with those due to GH deficiency. Furthermore, a condition of untreated GHD may mask concomitant pituitary deficiencies, mainly central hypothyroidism and hypoadrenalism. In this setting, the diagnosis could be delayed and possible only after recombinant human Growth Hormone (rhGH) replacement. Since inappropriate replacement of other pituitary hormones may exacerbate many manifestations of GHD, a correct diagnosis is crucial. This paper will focus on the main studies aimed to clarify the effects of GHD and rhGH replacement on other pituitary axes. Elucidating the possible contexts in which GHD may develop and examining the proposed mechanisms at the basis of interactions between the GH/IGF-I system and other axes, we will focus on the importance of a correct diagnosis to avoid possible pitfalls.

Abstract
INTRODUCTION Isolated adrenocorticotropic hormone (ACTH) deficiency (IAD) is a rare cause of adrenal insufficiency and T-box pituitary restricted transcription factor (TBX19) mutations are responsible for two-thirds of the neonatal onset form of the disease. IAD presents with hypoglycemia and prolonged jaundice in the neonatal period. TBX19 is important for both pro-opiomelanocortin (POMC) gene transcription and differentiation of POMC-expressing cells. We describe 2 patients, 1 with a reported and 1 with a novel TBX19 mutation, and present information about the long-term follow-up of these patients. CASE PRESENTATION Both patients had critical illnesses, recurrent hypoglycemia, convulsions, and neonatal hyperbilirubinemia. They also had low cortisol and ACTH levels, while other pituitary hormones were within the normal range. Pituitary imaging was normal. After hydrocortisone treatment, there was resolution of the hypoglycemia and the convulsions were controlled. Genetic studies of the patients revealed both had inherited a homozygous mutation of the TBX19 gene. The first patient had an alteration of NM_005149.3:c.856C>T (p.R286*) and the second patient had a novel NM_005149.3:c.584C>T (p.T195I) mutation, analyzed by next-generation sequencing. The noteworthy findings of the patients at follow-up were: short stature, microcephaly, and decreased pubic hair in the first, and dysmorphic features, Chiari type 1 malformation, tall stature, and low bone mineral density (BMD) in the second. CONCLUSION Congenital IAD can be life-threatening if it is not recognized and treated early. TBX19 mutations should be considered in the differential diagnosis of IAD. Further cases or functional analyses are needed for genotype-phenotype correlations. Low BMD, dysmorphic features, Chiari type 1 malformation, and sparse pubic hair are some of the important features in these patients.

Abstract
Cortisol and growth hormone (GH) deficiencies are causes of neonatal hypoglycemia. When they coexist, a pituitary disorder is suspected. We present an infant with hypoglycemia in whom an ACTH receptor defect was associated with transient GH deficiency. A full-term boy with consanguineous parents presented with hypoglycemia (serum glucose 18 mg/dL) at 4 hours of life with undetectable serum cortisol (<1 μg/dL). Examination showed diffuse hyperpigmentation with normal male genitalia. Patient developed hyperbilirubinemia and elevated transaminase levels. GH levels of 6.8 ng/mL and 7.48 ng/mL during episodes of hypoglycemia, peak of 9.2 ng/mL with glucagon stimulation, and undetectable IGF-1 suggested GH deficiency. Thyroid function, prolactin, and gonadotropins were normal. Baseline ACTH was elevated at 4868 pg/mL, whereas serum cortisol remained undetectable with ACTH stimulation. Hydrocortisone replacement resulted in normalization of blood glucose and cholestasis with decline in ACTH level. GH therapy was not initiated, given improvement in cholestasis and euglycemia. An ACTH receptor defect was confirmed with molecular genetic testing that revealed homozygosity for a known mutation of the melanocortin 2 receptor (MC2R) gene. At 12 weeks, a random GH level was 10 ng/mL. IGF-1 was 75 ng/mL and 101 ng/mL at 7 and 9 months, respectively. This report describes glucocorticoid deficiency from an MC2R mutation associated with GH deficiency. With glucocorticoid replacement, GH secretion normalized. Our findings are consistent with a previously stated hypothesis that physiologic glucocorticoid levels may be required for optimal GH secretion [1].

Abstract
Cushing's syndrome (CS) patients have increased mortality primarily due to cardiovascular events induced by glucocorticoid (GC) excess-related severe metabolic changes. Glucose metabolism abnormalities are common in CS due to increased gluconeogenesis, disruption of insulin signalling with reduced glucose uptake and disposal of glucose and altered insulin secretion, consequent to the combination of GCs effects on liver, muscle, adipose tissue and pancreas. Dyslipidaemia is a frequent feature in CS as a result of GC-induced increased lipolysis, lipid mobilisation, liponeogenesis and adipogenesis. Protein metabolism is severely affected by GC excess via complex direct and indirect stimulation of protein breakdown and inhibition of protein synthesis, which can lead to muscle loss. CS patients show changes in body composition, with fat redistribution resulting in accumulation of central adipose tissue. Metabolic changes, altered adipokine release, GC-induced heart and vasculature abnormalities, hypertension and atherosclerosis contribute to the increased cardiovascular morbidity and mortality. In paediatric CS patients, the interplay between GC and the GH/IGF1 axis affects growth and body composition, while in adults it further contributes to the metabolic derangement. GC excess has a myriad of deleterious effects and here we attempt to summarise the metabolic comorbidities related to CS and their management in the perspective of reducing the cardiovascular risk and mortality overall.

Abstract
Background DAVID syndrome is a rare condition combining anterior pituitary hormone deficiency with common variable immunodeficiency. NFKB2 mutations have recently been identified in patients with ACTH and variable immunodeficiency. A similar mutation was previously found in Nfkb2 in the immunodeficient Lym1 mouse strain, but the effect of the mutation on endocrine function was not evaluated. Methods We ascertained six unrelated DAVID syndrome families. We performed whole exome and traditional Sanger sequencing to search for causal genes. Lym1 mice were examined for endocrine developmental anomalies. Results Mutations in the NFKB2 gene were identified in three of our families through whole exome sequencing, and in a fourth by direct Sanger sequencing. De novo origin of the mutations could be demonstrated in three of the families. All mutations lie near the C-terminus of the protein-coding region, near signals required for processing of NFΚB2 protein by the alternative pathway. Two of the probands had anatomical pituitary anomalies, and one had growth and thyroid hormone as well as ACTH deficiency; these findings have not been previously reported. Two children of one of the probands carried the mutation and have to date exhibited only an immune phenotype. No mutations were found near the C-terminus of NFKB2 in the remaining two probands; whole exome sequencing has been performed for one of these. Lym1 mice, carrying a similar Nfkb2 C-terminal mutation, showed normal pituitary anatomy and expression of proopiomelanocortin (POMC). Conclusions We confirm previous findings that mutations near the C-terminus of NFKB2 cause combined endocrine and immunodeficiencies. De novo status of the mutations was confirmed in all cases for which both parents were available. The mutations are consistent with a dominant gain-of-function effect, generating an unprocessed NFKB2 super-repressor protein. We expand the potential phenotype of such NFKB2 mutations to include additional pituitary hormone deficiencies as well as anatomical pituitary anomalies. The lack of an observable endocrine phenotype in Lym1 mice suggests that the endocrine component of DAVID syndrome is either not due to a direct role of NFKB pathways on pituitary development, or else that human and mouse pituitary development differ in its requirements for NFKB pathway function.

Abstract
The diagnosis of GH deficiency (GHD) in childhood is a multistep process involving clinical history, examination with detailed auxology, biochemical testing, and pituitary imaging, with an increasing contribution from genetics in patients with congenital GHD. Our increasing understanding of the factors involved in the development of somatotropes and the dynamic function of the somatotrope network may explain, at least in part, the development and progression of childhood GHD in different age groups. With respect to the genetic etiology of isolated GHD (IGHD), mutations in known genes such as those encoding GH (GH1), GHRH receptor (GHRHR), or transcription factors involved in pituitary development, are identified in a relatively small percentage of patients suggesting the involvement of other, yet unidentified, factors. Genome-wide association studies point toward an increasing number of genes involved in the control of growth, but their role in the etiology of IGHD remains unknown. Despite the many years of research in the area of GHD, there are still controversies on the etiology, diagnosis, and management of IGHD in children. Recent data suggest that childhood IGHD may have a wider impact on the health and neurodevelopment of children, but it is yet unknown to what extent treatment with recombinant human GH can reverse this effect. Finally, the safety of recombinant human GH is currently the subject of much debate and research, and it is clear that long-term controlled studies are needed to clarify the consequences of childhood IGHD and the long-term safety of its treatment.

Abstract
Glucocorticoids modulate the secretion of growth hormone (GH) by various and competing effects on the hypothalamus and pituitary gland. The final effects of this modulation depend on hormone concentrations and the duration of exposure. The traditional hypothesis is that chronically raised levels of glucocorticoids suppress the secretion of GH. However, a functional impairment of the GH reserve might also be observed in patients with low levels of glucocorticoids, such as those with secondary hypoadrenalism, which is consistent with the model of biphasic dose-dependent effects of glucocorticoids on the somatotropic axis. This Review updates our current understanding of the mechanisms underlying the effects of glucocorticoids on the secretion of GH and the clinical implications of the dual action of glucocorticoids on the GH reserve in humans. This Review will also address the potential diagnostic and therapeutic implications of GH for patients with a deficiency or excess of glucocorticoids.

Abstract
BACKGROUND Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disorder characterised by isolated glucocorticoid deficiency. Mutations in the ACTH receptor/melanocortin 2 receptor (MC2R), the MC2R accessory protein (MRAP) or the STAR protein (STAR) cause FGD types 1, 2 and 3, respectively, accounting for ~50% of all cases. PATIENT AND METHODS We report a neonate of Indian origin, who was diagnosed with FGD in the first few days of life. He presented with hypoglycaemic seizures and was noted to have generalised intense hyperpigmentation and normal male genitalia. Biochemical investigations revealed hypocortisolaemia (cortisol 0.223 μg/dl; NR 1-23 μg/dl) and elevated plasma ACTH (170 pg/ml). Serum electrolytes, aldosterone and plasma renin activity were normal. Peak cortisol following a standard synacthen test was 0.018 μg/dl. He responded to hydrocortisone treatment and continues on replacement. Patient DNA was analysed by direct sequencing. The effect of the novel mutation was assessed by an in vitro splicing assay using wild type and mutant heterologous minigenes. RESULTS A novel homozygous mutation c.106+2_3dupTA was found in the MRAP gene. Both parents were heterozygous for the mutation. In an in vitro splicing assay, the mutation resulted in the skipping of exon 3. CONCLUSION We have identified a novel MRAP mutation where disruption of the intron 3 splice-site results in a prematurely terminated translation product. This protein (if produced) would lack the transmembrane domain that is essential for MC2R interaction. We predict that this would cause complete lack of ACTH response thus explaining the early presentation in this case.

Abstract
Background Congenital isolated adrenocorticotrophic hormone (ACTH) deficiency may be rare, but it could be an underestimated cause of neonatal death. Our objective was to shorten the time between first symptoms and diagnosis. Methods This single-centre retrospective case-cohort study was carried out on eight consecutive patients. Results Two had the neonatal form and 6 the late onset form. Six were admitted to an intensive care unit at least once for seizures with hypoglycemia, major hypothermia, fever, and/or collapsus. The 2 neonatal cases presented with hypoglycemia and in a state of “apparent death” at birth or hypothermia (29°C) at 6 days. All 6 late onset cases had also been admitted to an emergency department 1–3 times, but had left hospital incorrectly diagnosed. Their first symptoms were noted at 3–12.3 years, and they were diagnosed at 3.3–14.4 years. All had hypoglycemia, and 4 had had seizures. The presenting symptoms were vomiting and/or abdominal pain, asthenia, irritability, difficulty with physical activities, and anorexia. The school performance of 4 deteriorated. Two underwent psychotherapy and treatment for depression, which was stopped when Hydrocortisone® replacement therapy began. The plasma concentrations in spontaneous hypoglycemia were: ACTH<5 to 17.1 pg/mL, with concomitant cortisol <3.5 to 37 ng/mL. The plasma dehydroepiandrosterone sulfate (DHAS) concentrations were low in the 7 evaluated. The coding sequence of TPIT was normal in all. Conclusion Several unexplained symptoms in a child, mainly gastro-intestinal symptoms and seizures due to hypoglycemia, may indicate ACTH deficiency. A low or normal basal plasma ACTH despite concomitant low cortisol at 8 a.m. and/or in spontaneous hypoglycemia, associated with low DHAS, in a patient not given corticosteroids is highly suggestive of ACTH deficiency. The isolated character of ACTH deficiency must be confirmed by determining the other hypothalamic-pituitary functions, and Hydrocortisone® replacement therapy initiated in emergency.
