Endocrine 2023; 82:467-479. [PMID: 37731140 PMCID: PMC10618385 DOI: 10.1007/s12020-023-03492-7] [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: 06/28/2023] [Accepted: 08/10/2023] [Indexed: 09/22/2023]
Abstract
Secondary diabetes mellitus (DM) in secretory pheochromocytomas and paragangliomas (PPGLs) is encountered in up to 50% of cases, with its presentation ranging from mild, insulin resistant forms to profound insulin deficiency states, such as diabetic ketoacidosis and hyperglycemic hyperosmolar state. PPGLs represent hypermetabolic states, in which adrenaline and noradrenaline induce insulin resistance in target tissues characterized by aerobic glycolysis, excessive lipolysis, altered adipokine expression, subclinical inflammation, as well as enhanced gluconeogenesis and glucogenolysis. These effects are mediated both directly, upon adrenergic receptor stimulation, and indirectly, via increased glucagon secretion. Impaired insulin secretion is the principal pathogenetic mechanism of secondary DM in this setting; yet, this is relevant for tumors with adrenergic phenotype, arising from direct inhibitory actions in beta pancreatic cells and incretin effect impairment. In contrast, insulin secretion might be enhanced in tumors with noradrenergic phenotype. This dimorphic effect might correspond to two distinct glycemic phenotypes, with predominant insulin resistance and insulin deficiency respectively. Secondary DM improves substantially post-surgery, with up to 80% remission rate. The fact that surgical treatment of PPGLs restores insulin sensitivity and secretion at greater extent compared to alpha and beta blockade, implies the existence of further, non-adrenergic mechanisms, possibly involving other hormonal co-secretion by these tumors. DM management in PPGLs is scarcely studied. The efficacy and safety of newer anti-diabetic medications, such as glucagon-like peptide 1 receptor agonists and sodium glucose cotransporter 2 inhibitors (SGLT2is), as well as potential disease-modifying roles of metformin and SGLT2is warrant further investigation in future studies.

Abstract
Hypoglycemia is due to defects in the metabolic systems involved in the transition from the fed to the fasting state or in the hormone control of these systems. In children, hypoglycemia is considered a metabolic-endocrine emergency, because it may lead to brain injury, permanent neurological sequelae and, in rare cases, death. Symptoms are nonspecific, particularly in infants and young children. Diagnosis is based on laboratory investigations during a hypoglycemic event, but it may also require biochemical tests between episodes, dynamic endocrine tests and molecular genetics. This narrative review presents the age-related definitions of hypoglycemia, its pathophysiology and main causes, and discusses the current diagnostic and modern therapeutic approaches.

Abstract
Primary aldosteronism (PA) and diabetes mellitus (DM) are clinical conditions that increase cardiovascular risk. Approximately one in five patients with PA have DM. Nevertheless, the pathophysiology linking these two entities is not entirely understood. In addition, the majority of patients with PA have glucocorticoid co-secretion, which is associated with increased risk of impaired glucose homeostasis. In the present review, we aim to comprehensively discuss all the available research data concerning the interplay between mineralocorticoid excess and glucose metabolism, with separate analysis of the sequalae in muscle, adipose tissue, liver and pancreas. Aldosterone binds both mineralocorticoid and glucocorticoid receptors and amplifies tissue glucocorticoid activity, via 11-β-hydroxysteroid dehydrogenase type 1 stimulation. A clear classification of the molecular events as per specific receptor in insulin-sensitive tissues is impossible, while their synergistic interaction is plausible. Furthermore, aldosterone induces oxidative stress and inflammation, perturbs adipokine expression, thermogenesis and lipogenesis in adipose tissue, and increases hepatic steatosis. In pancreas, enhanced oxidative stress and inflammation of beta cells, predominantly upon glucocorticoid receptor activation, impair insulin secretion. No causality between hypokalemia and impaired insulin response is yet proven; in contrast, hypokalemia appears to be implicated with insulin resistance and hepatic steatosis. The superior efficacy of adrenalectomy in ameliorating glucose metabolism vs. mineralocorticoid receptor antagonists in clinical studies highlights the contribution of non-mineralocorticoid receptor-mediated mechanisms in the pathophysiologic process. The exact role of hypokalemia, the mechanisms linking mineralocorticoid excess with hepatic steatosis, and possible disease-modifying role of pioglitazone warrant further studies.

Abstract
Obesity is often accompanied by major depressive disorder (MDD), and vice versa. Latest research findings suggest the body mass index (BMI) to play a role in antidepressant treatment response in general. Our study aims to examine whether adiposity-related parameters such as BMI, glucose homeostasis, or serum lipids are associated with remission to electroconvulsive therapy (ECT). A pilot study (PS, n = 9) and a glucose study (GS, n = 29) were conducted. Blood was withdrawn directly before and 15 min (GS) as well as 1 h (PS) after the first ECT and directly before the last one (usually an ECT series comprised up to twelve sessions). BMI was associated with remission in the PS (remitters: M = 28, SD = 2.5; non-remitters: M = 22, SD = 2.08; t(7) = 3.325, p < 0.001, d = 0.24) but not in the GS or when pooled together. Glucose and insulin levels increased significantly after a single ECT session (GS: glucose: F (2,25.66) = 39.04, p < 0.001; insulin: PS: F (2,83) = 25.8, p < 0.001; GS: F (2,25.87) = 3.97, p < 0.05) but no chronic effect was detectable. Serum lipids were neither significantly altered after a single ECT session nor during a whole course of ECT. There was no difference between remitters and non-remitters in insulin, glucose, or serum lipid levels. Our study is lacking the differentiation between abdominal and peripheral fat distribution, and the sample size is small. Unexpectedly, BMI, glucose homeostasis, and lipid serum levels did not differ in patients remitting during ECT. In contrast to recently published studies, we cannot confirm the hypothesis that BMI may have an impact on ECT response.

Abstract
Background Studies have shown that hyperglycemia in cirrhotic patients increases mortality. However, no population-based study has evaluated the influence of hypoglycemia upon hospital admission on death in these patients. The aim of this study was to assess the effect of hypoglycemia at admission on the mortality of patients with liver cirrhosis. Methods The Taiwan National Health Insurance Database was searched, and 636 cirrhotic patients without baseline diabetes mellitus who presented with hypoglycemia upon hospitalized from 2010 to 2013 were included in the study. A one-to-four propensity score matching was performed to select a comparison group based on age, sex and comorbidities. Results The overall 30-day mortality rate was 30.2% in the hypoglycemia group and 7.4% in the non-hypoglycemia group (P < 0.001). After Cox regression modeling adjusting for age, sex and comorbid disorders, cirrhotic patients with hypoglycemia had a hazard ratio (HR) of 30-day mortality of 4.96 (95% confidence interval [CI] 4.05–6.08, P < 0.001) as compared to the non-hypoglycemia group. In subgroup analysis, the cirrhotic patients with hypoglycemia and hepatocellular carcinoma (HCC) had a 30-day mortality HR of 6.11 (95% confidence interval [CI] 4.40–8.49, P < 0.001) compared to those with neither hypoglycemia nor HCC. Conclusions Hypoglycemia is a very important prognostic factor in the 30-day mortality of cirrhotic patients, especially in those with underlying HCC.

Abstract
PURPOSE Angiotensin converting enzyme 2 (ACE2) is the door for SARS-CoV-2, expressed in critical metabolic tissues. So, it is rational that the new virus causes pleiotropic alterations in glucose metabolism, resulting in the complication of pre-existing diabetes's pathophysiology or creating new disease mechanisms. However, it seems that less attention has been paid to this issue. This review aimed to highlight the importance of long-term consequences and pleiotropic alterations in glucose metabolism following COVID-19 and emphasize the need for basic and clinical research in metabolism and endocrinology. RESULTS SARS-CoV-2 shifts cellular metabolism from oxidative phosphorylation to glycolysis, which leads to a decrease in ATP generation. Together with metabolic imbalance, the impaired immune system elevates the susceptibility of patients with diabetes to this deadly virus. SARS-CoV-2-induced metabolic alterations in immune cells can result in hyper inflammation and a cytokine storm. Metabolic dysfunction may affect therapies against SARS-CoV-2 infection. The effective control of metabolic complications could prove useful therapeutic targets for combating COVID-19. It is also necessary to understand the long-term consequences that will affect patients with diabetes who survived COVID-19. CONCLUSIONS Since the pathophysiology of COVID-19 is still mostly unknown, identifying the metabolic mechanisms contributing to its progression is essential to provide specific ways to prevent and improve this dangerous virus's detrimental effects. The findings show that the new virus may induce new-onset diabetes with uncertain metabolic and clinical features, supporting a potential role of COVID-19 in the development of diabetes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE 'Salt-processed Psoraleae Fructus & salt-processed Foeniculi Fructus' (sPF&sFF) is a common Chinese medicinal combination for treating diarrhoea. However, it is not clear how sPF and sFF work together, and why salt-processing is necessary. AIM OF THE STUDY To investigate the compatibility mechanism of sPF&sFF and the influence of salt-processing on it. MATERIALS AND METHODS Firstly, the metabolomics approach was appliedto screen the differential components between four (s)PF&(s)FF extracts, i.e., sPF&sFF, sPF&FF, PF&sFF, and PF&FF extracts. Then, an in vivo metabolomics study was carried out to filter critical metabolites reflecting the curative effects of (s)PF&(s)FF, and construct a metabolic network. Finally, a correlation analysis between chemical components in extracts and critical metabolites in vivo was performed to find out the synergistic and/or antagonistic effects between herbs as well as the influence of salt-processing. RESULTS Salt-processing had a direct influence on the contents of chemical components in sPF and sFF extracts, and there existed positive/negative correlations between the content change of chemical components and the effects of critical metabolites. Therefore, salt-processing indirectly affected on these correlations and was (i) conducive to the positive effects of sPF and sFF on bile acids, making sFF play a synergistic role, thereby, sPF&sFF could perform better than sPF and other three combinations and effectively relieve the symptoms of fatty diarrhoea, osmotic diuresis, malnutrition, and weight loss; (ii) conducive to the positive effects of sPF on triacylglycerol, 12(S)-hydroxyeicosatetraenoic acid, cholesterol, and arachidonic acid, and adverse to that of sFF, making sFF play an antagonistic role, thereby, sPF&sFF could prevent a series of side effects caused by over-regulation and suitably relieve the symptoms of osmotic diuresis, polyuria, malnutrition, and weight loss; and (iii) adverse to the positive effects of sPF and sFF on thromboxane A2, sphinganine and sphingosine, making sFF play a synergistic role, thereby, sPF&sFF could prevent a series of side effects and moderately relieve the symptoms of metabolic diarrhoea and polyuria. CONCLUSIONS Salt-processing indirectly affected on the correlations between chemical components in extracts and critical metabolites in vivo, and exhibited both conducive and adverse effects on the efficacy, making sPF and sFF cooperate with each other to moderately repair the metabolic disorders. Thereby, sPF&sFF could suitably relieve the diarrhoea and polyuria symptoms in the model and exert the most appropriate efficacy. Moreover, this novel strategy provided a feasible approach for further studying the compatibility mechanism of herbs.

Abstract
The adrenal glands have striking morpho-biochemical features that render them vulnerable to the effects of toxins. AIMS This study was conducted to explore the therapeutic utility of extracellular vesicles derived from bone marrow mesenchymal stem cells (BMSC-EVs) against fluoride-induced adrenal toxicity. MATERIALS AND METHODS The work included isolation and further identification of BMSC-EVs by transmission electron microscopy and flow cytometric analysis. Adrenal toxicity in rats was induced by oral administration of 300 ppm of sodium fluoride (NaF) in drinking water for 60 days followed by a single dose injection of BMSC-EVs. The effects of BMSC-EVs against NaF was evaluated by adrenal oxidant/antioxidant biomarkers, hormonal assay of plasma adrenocorticotrophic hormone (ACTH) and corticosterone (CORT) and mRNA gene expression quantitation for adrenal cortical steroidogenic pathway-encoding genes. Histopathological examination of the adrenal tissue was performed. KEY FINDINGS BMSC-EVs were effectively isolated and characterized. NaF exposure decreased adrenal superoxide dismutase and catalase activities, increased adrenal malondialdehyde levels, elevated plasma ACTH, diminished CORT concentrations and downregulated the adrenal cortical steroidogenic pathway-encoding genes. In addition, NaF-induced marked adrenal histopathological lesions. SIGNIFICANCE BMSC-EVs treatment repaired damaged adrenal tissue and recovered its function greatly following NaF consumption. BMSC-EVs reversed the toxic effects of NaF and reprogramed injured adrenal cells by activating regenerative processes.

Abstract
Hypoglycemia is the result of defects/impairment in glucose homeostasis. The main etiological causes are metabolic and/or endocrine and/or other congenital disorders. Despite hypoglycemia is one of the most common emergencies in neonatal age and childhood, no consensus on the definition and diagnostic work-up exists yet. Aims of this review are to present the current age-related definitions of hypoglycemia in neonatal-pediatric age, to offer a concise and practical overview of its main causes and management and to discuss the current diagnostic-therapeutic approaches. Since a systematic and prompt approach to diagnosis and therapy is essential to prevent hypoglycemic brain injury and long-term neurological complications in children, a comprehensive diagnostic flowchart is also proposed.

Abstract
This review aims to explore, present, and discuss disorders of glucose metabolism implicated in pituitary gland diseases, the appropriate interventions, as well as the therapeutic challenges that may arise. Pituitary pathologies may dysregulate glucose homeostasis, as both the excess and deficiency of various pituitary hormones can affect glucose metabolism. Increased circulating levels of growth hormone, glucocorticoids or prolactin have been shown to mainly provoke hyperglycemic states, while hypopituitarism can be associated with both hyperglycemia and hypoglycemia. Addressing the primary cause of these disorders with the use of surgery, medical treatment or radiotherapy forms the cornerstone of current management strategies. Physicians should bear in mind that some such medications have an unfavorable effect on glucose metabolism too. When unsuccessful, or until the appropriate treatment of the underlying pituitary problem, the addition of established antidiabetic therapies might prove useful. Further studies aiming to discover more accurate and effective drug preparations in combination with optimal lifestyle management models will contribute to achieving a more successful glycemic control in these patients.
