Abstract
Sarcopenic obesity is characterized by a concurrent decline in muscle mass and function, along with increased adipose tissue. Sarcopenic obesity is a growing concern in older adults owing to significant health consequences, including implications for mortality, comorbidities and risk of developing geriatric syndromes. A 2022 consensus statement established a new definition and diagnostic criteria for sarcopenic obesity. The pathophysiology of this condition involves a complex interplay between muscle, adipose tissue, hormonal changes, inflammation, oxidative stress and lifestyle factors, among others. Sarcopenic obesity is treated with a range of management approaches, such as lifestyle interventions, exercise, nutrition and medical therapies. Emerging therapies that were developed for treating other conditions may be relevant to sarcopenic obesity, including novel pharmacological agents and personalized approaches such as precision medicine. In this Review, we synthesize the current knowledge of the clinical importance of sarcopenic obesity, its assessment and diagnosis, along with current and emerging management strategies.

Abstract
Patients with chronic kidney disease (CKD) experience a several-fold increased risk of fracture. Despite the high incidence and the associated excess morbidity and premature mortality, bone fragility in CKD, or CKD-associated osteoporosis, remains a blind spot in nephrology with an immense treatment gap. Defining the bone phenotype is a prerequisite for the appropriate therapy of CKD-associated osteoporosis at the patient level. In the present review, we suggest 10 practical 'tips and tricks' for the assessment of bone health in patients with CKD. We describe the clinical, biochemical, and radiological evaluation of bone health, alongside the benefits and limitations of the available diagnostics. A bone biopsy, the gold standard for diagnosing renal bone disease, is invasive and not widely available; although useful in complex cases, we do not consider it an essential component of bone assessment in patients with CKD-associated osteoporosis. Furthermore, we advocate for the deployment of multidisciplinary expert teams at local, national, and potentially international level. Finally, we address the knowledge gaps in the diagnosis, particularly early detection, appropriate "real-time" monitoring of bone health in this highly vulnerable population, and emerging diagnostic tools, currently primarily used in research, that may be on the horizon of clinical practice.

In Vitro Assessment of Cortisol Release Inhibition, Bioaccessibility and Bioavailability of a Chemically Characterized Scutellaria lateriflora L. Hydroethanolic Extract. Molecules 2024; 29:586. [PMID: 38338331 PMCID: PMC10856628 DOI: 10.3390/molecules29030586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 01/21/2024] [Accepted: 01/22/2024] [Indexed: 02/12/2024] Open
Abstract
Excess cortisol release is associated with numerous health concerns, including psychiatric issues (i.e., anxiety, insomnia, and depression) and nonpsychiatric issues (i.e., osteoporosis). The aim of this study was to assess the in vitro inhibition of cortisol release, bioaccessibility, and bioavailability exerted by a chemically characterized Scutellaria lateriflora L. extract (SLE). The treatment of H295R cells with SLE at increasing, noncytotoxic, concentrations (5-30 ng/mL) showed significant inhibition of cortisol release ranging from 58 to 91%. The in vitro simulated gastric, duodenal, and gastroduodenal digestions, induced statistically significant reductions (p < 0.0001) in the bioactive polyphenolic compounds that most represented SLE. Bioavailability studies on duodenal digested SLE, using Caco-2 cells grown on transwell inserts and a parallel artificial membrane permeability assay, indicated oroxylin A glucuronide and oroxylin A were the only bioactive compounds able to cross the Caco-2 cell membrane and the artificial lipid membrane, respectively. The results suggest possible applications of SLE as a food supplement ingredient against cortisol-mediated stress response and the use of gastroresistant oral dosage forms to partially prevent the degradation of SLE bioactive compounds. In vivo studies and clinical trials remain necessary to draw a conclusion on the efficacy and tolerability of this plant extract.

Abstract
Prolonged exposure to an excess of glucocorticosteroids (GCs), both endogenous and exogenous, leads to a wide range of comorbidities, including cardiovascular, metabolic, psychiatric, and musculoskeletal disorders. The latter comprise osteopenia and osteoporosis leading to skeletal fractures and myopathy. Although endogenous hypercortisolemia is a rare disorder, GCs are among the most frequently prescribed drugs, often administered chronically and despite multiple side effects, impossible to taper off due to therapeutic reasons. The pathophysiology of the effect of GC excess on bone often leads to fractures despite normal or low-normal bone mineral density and it includes direct (mainly disturbance in bone formation processes, through inactivation of the Wnt/β-catenin signalling pathway) and indirect mechanisms (through suppressing the gonadal and somatotrophic axis, and also through antagonizing vitamin D actions). Glucocorticosteroid-induced fast-twitch, glycolytic muscles atrophy occurs due to increased protein catabolism and impaired synthesis. Protein degradation is a result of activation of the ubiquitin proteasome and the lysosomes stimulated through overexpression of several atrogenes (such as FOXO-1 and atrogin-1). This review will discuss pathophysiology, clinical presentation, prevention, and management of GC-induced osteoporosis (including calcium and vitamin D supplementation, and bisphosphonates) and myopathy associated with GC excess.

Abstract
PURPOSE Hypercortisolism has detrimental effects on bone metabolism with the consequences of bone loss and bone fractures. We aimed to evaluate the frequency of vertebral fragility fractures and to determine the factors associated with Cushing's syndrome (CS). METHODS A total of 135 patients diagnosed with Cushing's syndrome [108 patients with Cushing's disease and 27 patients with adrenocortical adenoma] and 107 healthy controls were included in this cross-sectional study. The available clinical, laboratory, and radiologic data of patients with CS were recorded, retrospectively. Lateral vertebral radiograms were evaluated for vertebral fragility fractures according to Genant's semi-quantitative method. Bone mineral density (BMD) was determined using a Dual-energy X-ray absorptiometry (DEXA). RESULTS Vertebral fragility fractures (VFs) were observed in 75.3% (n = 61) of the patients. The median number of VFs was six (min-max: 2-12). All patients with vertebral fractures had thoracic VF, and 50.7% of the patients had lumbar fragility fractures. Thirty-three (40.7%) patients with vertebral fractures had normal bone densitometry values. Osteoporosis and osteopenia were observed in 16.2% and 40.7% of the patients, respectively. The duration of active disease, the presence of ACTH-secreting pituitary adenoma, and 24-h urinary cortisol did not influence the presence of vertebral fractures. Vertebral fractures were independently associated with age, FSH, LH levels, and lumbar BMD (R2 = 68.18%, p = 0.028). The femoral neck BMD (but not lumbar BMD) was independently associated with age, BMI, and PTH levels (R2 = 48.48%, p < 0.001). CONCLUSION Vertebral fracture frequency was higher in CS patients. Most of the patients with vertebral fractures had multiple fractures. Although low lumbar BMD was associated with VF, patients with CS with normal bone densitometry could experience VF. Vertebral radiograph evaluations as a part of routine evaluation for silent vertebral fractures may help to prevent further fractures in patients with CS.

A General Mechano-Pharmaco-Biological Model for Bone Remodeling Including Cortisol Variation. MATHEMATICS 2021.

Abstract
The process of bone remodeling requires a strict coordination of bone resorption and formation in time and space in order to maintain consistent bone quality and quantity. Bone-resorbing osteoclasts and bone-forming osteoblasts are the two major players in the remodeling process. Their coordination is achieved by generating the appropriate number of osteoblasts since osteoblastic-lineage cells govern the bone mass variation and regulate a corresponding number of osteoclasts. Furthermore, diverse hormones, cytokines and growth factors that strongly link osteoblasts to osteoclasts coordinated these two cell populations. The understanding of this complex remodeling process and predicting its evolution is crucial to manage bone strength under physiologic and pathologic conditions. Several mathematical models have been suggested to clarify this remodeling process, from the earliest purely phenomenological to the latest biomechanical and mechanobiological models. In this current article, a general mathematical model is proposed to fill the gaps identified in former bone remodeling models. The proposed model is the result of combining existing bone remodeling models to present an updated model, which also incorporates several important parameters affecting bone remodeling under various physiologic and pathologic conditions. Furthermore, the proposed model can be extended to include additional parameters in the future. These parameters are divided into four groups according to their origin, whether endogenous or exogenous, and the cell population they affect, whether osteoclasts or osteoblasts. The model also enables easy coupling of biological models to pharmacological and/or mechanical models in the future.

Abstract
The role of tissue specific metabolism of endogenous glucocorticoids (GCs) in the pathogenesis of human disease has been a field of intense interest over the last 20 years, fuelling clinical trials of metabolism inhibitors in the treatment of an array of metabolic diseases. Localised pre-receptor metabolism of endogenous and therapeutic GCs by the 11β-hydroxysteroid dehydrogenase (11β-HSD) enzymes (which interconvert endogenous GCs between their inactive and active forms) are increasingly recognised as being critical in mediating both their positive and negative actions on bone homeostasis. In this review we explore the roles of endogenous and therapeutic GC metabolism by the 11β-HSD enzymes in the context of bone metabolism and bone cell function, and consider future strategies aimed at modulating this system in order to manage and treat various bone diseases.

Abstract
PURPOSE The aim of this study was to compare phenotype of patients with pituitary, adrenal and ectopic CS and identify the differences regarding biochemical parameters, clinical presentations, and comorbidities in CS patients who were diagnosed at the single endocrinological center in Wroclaw. METHODS The study population involved 64 patients with CS (53 women and 11 men) diagnosed in Department of Endocrinology, Diabetes and Isotope Therapy in 2000-2018. Patients were divided into three etiologic groups: pituitary dependent-CS (P-CS) (64%), adrenal dependent CS (A-CS) (25%), and CS from an ectopic source (E-CS) (11%). RESULTS Percentage of men in the A-CS group was significantly higher than in the other etiologic groups. ACTH, UFC, and cortisol in DST were significantly higher in E-CS group compare to P-CS and A-CS (p < 0.05). Mean potassium level in E-CS group was significantly lower than in P-CS and A-CS (p < 0.05). Median of time elapsed to diagnosis was significantly lower in the E-CS group compared with either the P-CS and the A-CS group (p < 0.01). The most frequently symptoms in CS patients were skin alterations (82.8%), weight gain (81.2%), and hypertension (81.2%). CONCLUSIONS The epidemiology of CS is changing toward a growing proportion of A-CS. All patients with E-CS presented a profound hypokalemia. Salient hypokalemia could be a biochemical marker more suggestive for E-CS rather than P-CS. The incidence of diabetes is more frequent in E-CS group than in P-CS and A-CS groups.

Abstract
INTRODUCTION Endogenous or exogenous (corticosteroid-induced) glucocorticoids (GCs) excess represents, together with diabetes, the most common cause of secondary osteoporosis. AREAS COVERED We present a comprehensive overview about the pathophysiology, clinical management and treatment of GCs induced osteoporosis (GIOP). According to PRISMA guidelines, a literature search identifying articles about bone and GCs was done. EXPERT OPINION Despite the progress over the years and the increase in therapeutic options, there still are controversial issues about the management of GIOP. These mainly include the failure of BMD or FRAX to completely account for the rapid increase in fracture risk of most GC-treated patients, the understanding about the independent contribution on bone fragility of the underlying disease requiring GCs therapy, and the necessity of clearer information about the anti-fracture efficacy and long term-safety of most therapeutic options. Moreover, there are no specific indications for the management of bone fragility in endogenous hypercortisolism. Notwithstanding the above limitations there is a general consensus to recommend an assessment of fracture risk in all individuals >40 years committed to receive (or continuing) high dose (>7.5 mg of prednisone equivalent) GCs for ≥3 months and in all patients with fragility fracture history.

Abstract
Reports on the effects of hyperadrenocorticism (HAC) on bone turnover in dogs are largely confined to radiographic studies. The aim of this study was to more accurately assess bone turnover in dogs with HAC by measuring circulating total and ionized calcium and phosphate concentrations, both intact and whole parathyroid hormone (PTH) concentrations and markers of both osteoblastic (osteocalcin) and osteoclastic [carboxyterminal cross-linked telopeptide of type 1 collagen (ICTP) and urine aminoterminal telopeptide of type 1 collagen (NTX) activity]. Dogs with HAC and a control group were prospectively enrolled for comparison. Results from 49 dogs with HAC were compared with 39 dogs from a hospital control population. Plasma intact and whole PTH concentrations were determined using a human immunoradiometric assay. Serum osteocalcin and NTX concentrations were measured using human enzyme linked immunosorbent assays. Serum ICTP concentration was measured using a human radioimmunoassay. Total calcium concentrations in dogs with HAC (2.67 ± 0.25 mmol/L) were not significantly different than in the control group (2.67 ± 0.14 mmol/L). By contrast, phosphate concentrations were significantly (P = 0.0143) higher in dogs with HAC (1.46 ± 0.30 mmol/L) compared to the control group (1.28 ± 0.33 mmol/L). The median intact PTH concentration in HAC dogs was 9.25 (range, 1.34–95.45) pmol/L, which was significantly (P < 0.0001) higher than in the control group [median, 3.88 (range, 2.01–10.31) pmol/L]. Whole PTH concentrations were also significantly (P < 0.0001) higher in the HAC group [median, 4.61 (range, 0.56–125.16) pmol/L] compared to the control group [median, 1.83 (range, 0.88–6.81) pmol/L]. Serum osteocalcin and urine NTX concentrations were not significantly different between the two groups of dogs. The median ICTP concentration in dogs with HAC was 2.98 (range, 1.15–6.62) ng/mL which was significantly (P < 0.0001) lower than in the control dogs [median, 7.30 (range, 3.68–21.25) ng/mL]. Both whole and intact PTH concentrations are increased in dogs with HAC compared to a hospital control population. This does not however appear to be associated with a decrease in bone formation (as assessed by osteocalcin) or an increase in bone resorption (as assessed by ICTP and urine NTX).

Abstract
INTRODUCTION Glucocorticoid (GC) induced osteoporosis (GIOP) is the most common form of secondary osteoporosis. It develops in a dose and time dependent manner, due to a rapid and transient increase in bone resorption, followed by the inhibition of bone formation. AREAS COVERED In this review, the authors summarize the pathophysiology of GIOP and give discussion to the clinical management of patients taking GCs, focusing on the currently available drugs that have antiresorptive or anabolic activity on bone. EXPERT OPINION Despite the widespread use of GCs and their well-established detrimental skeletal effects, GIOP remains an under-diagnosed and under-treated condition. Indeed, the clinical management of GIOP is still debated, so that the recent guidelines differ in their indications for pharmacological intervention. Either bone mineral density (BMD) or algorithms such as FRAX do not completely account for the remarkable and rapid increase in fracture risk of most GC-treated patients. Moreover, while oral bisphosphonates remain the most used and cost-effective option, the potential increased benefits of more potent antiresorptive agents (e.g. denosumab and zoledronate) or anabolic compounds (e.g. teriparatide) warrant further investigation. Despite the above limitations, the assessment of fracture risk is recommended for all individuals committed to receiving oral GCs for 3 months or longer.

Abstract
Cortisol is an important steroid hormone in human physiology. Variations or abnormalities in the physiological cortisol levels control acute and chronic stress response, as well as contribute to diseases and syndromes including Addison's disease and Cushing syndrome. The ability to monitor cortisol levels in the physiological range is key in diagnosis and monitoring of these conditions, where current methodology for determination of cortisol levels relies on instrumentation that requires extensive sample preparation, long run times, and is destructive to the sample. Raman spectroscopy provides rapid sample analysis with relatively simple instrumentation; however, Raman spectroscopy is an inherently weak technique. To provide an enhanced Raman signal, we use surface enhanced Raman spectroscopy (SERS) which utilizes oscillating electric fields of metal nanoparticles, enhancing the overall electric field and therefore resulting in an enhanced signal. We demonstrate SERS-based detection of cortisol in the physiologically relevant range using colloidal silver nanoparticles in ethanolic solutions and bovine serum albumin. The SERS spectra obtained in an ethanol matrix demonstrate a sigmoidal concentration response over the physiologically relevant concentration range, with a limit of detection established at 177 nM. Analysis of cortisol solutions in a complex matrix (bovine serum albumin in phosphate buffered saline) is also demonstrated through the use of principal components analysis, a multivariate technique, which shows the separation of cortisol in a linear fashion with respect to cortisol concentration.

Abstract
An underlying disease affecting bone health is present in up to 40% and 60% of osteoporotic post-menopausal women and men respectively. Among the disorders leading to a secondary form of osteoporosis, the endocrine diseases are highly represented. A frequent finding in patients affected with an endocrine-related forms of bone disease is that the skeletal fragility is partially independent of the bone density, since the fracture risk in these patients is related more to a reduction of bone quality than to a decrease of bone mass. As a consequence, bone mineral density evaluation by dual-X-ray Absorptiometry may be inadequate for establishing the risk of fracture in the setting of the endocrine-related forms of osteoporosis. In the recent years several attempts to non-invasively estimating bone quality have been done. Nowadys, some new tools are available in the clinical practice for optimizing the fracture risk estimation in patients with endocrine disorders. The aim of this review is to summarise the evidences regarding the role of the different imaging tools for evaluating bone density and bone quality in the most frequent forms of endocrine-related osteoporosis, such as obesity, diabetes, acromegaly, thyrotoxicosis, primary hyperparathyroidism, hypercortisolism and hypogonadism. For each of these disorders, data regarding both the current available tools and the future possible new techniques for assessing bone fragility in patients with endocrine diseases are reported.

Abstract
INTRODUCTION The term secondary osteoporosis (SO) identifies a reduction of bone mass related to a well-established disease or pharmacological agent. The identification of the underlying disease often represents a challenging situation in clinical practice. AREAS COVERED The prevalence of SO in the real world may vary, ranging from 17% to 80%; therefore, search for a form of SO represents a pillar when evaluating patients with osteoporosis. Guidelines for treatment of specific secondary forms of osteoporosis, such as glucocorticoid-induced osteoporosis, have been published even though often neglected in clinical practice. For the majority of SO, there are currently no specific guidelines concerning treatment with only few trials showing the effect of bone-active drugs on fracture risk reduction. EXPERT OPINION Healthcare professionals should be aware of the secondary forms of osteoporosis, in particular when the reason for reduced skeletal resistance is uncertain or when bone mineral density results are unsatisfactory in a patient compliant to therapy. In a few cases (such as, for example: no response to therapy, better classification of bone involvement in patients with kidney failure, suspicion of rare metabolic bone disease) bone biopsy is needed to investigate the patient. This review highlights recent advances in understanding and managing SO.

Abstract
UNLABELLED Despite ethnic differences in cortisol sensitivity, only one study in Caucasians has assessed trabecular bone score (TBS) in patients with subclinical hypercortisolism (SH). We showed that both subtle cortisol excess and reduced adrenal androgen may contribute to impaired bone quality in Asian women with SH. INTRODUCTION One study in Caucasians has assessed trabecular bone score (TBS), an index of bone microstructure, in adrenal incidentaloma (AI) patients with subclinical hypercortisolism (SH). There are ethnic differences in cortisol sensitivities between Caucasian and Asian populations. We investigated the associations of cortisol and the adrenal androgen dehydroepiandrosterone-sulfate (DHEA-S) with TBS in AI patients with SH, adrenal Cushing's syndrome (CS), and nonfunctional AI (NFAI). METHODS We measured TBS, cortisol levels after the overnight 1 mg dexamethasone suppression test (1 mg DST), and cortisol/DHEA-S in 61 patients with SH (30 men; 31 women), 19 with adrenal CS (4 men; 15 women), and 355 with NFAI (213 men; 142 women). RESULTS After adjusting for confounders, the serum cortisol level after 1 mg DST was inversely correlated with TBS in men (β = -0.133, P = 0.045) and women (β = - 0.140, P = 0.048). Higher cortisol/DHEA-S ratio was associated with lower TBS in women (β = - 0.252, P < 0.001), but not men. This inverse association of cortisol/DHEA-S ratio in women remained statistically significant after adjusting for the serum cortisol level after 1 mg DST (β = - 0.221, P = 0.008). Compared with women with NFAI, women with SH had 2.2% lower TBS (P = 0.040). Deteriorated bone microstructure (TBS < 1.230) was associated with the serum cortisol level after 1 mg DST (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.04-4.53) and cortisol/DHEA-S ratio (OR, 2.05; 95% CI, 1.03-4.08). CONCLUSIONS Subtle cortisol excess in both genders and reduced DHEA-S, especially in women, may contribute to impaired bone quality in Asian patients with SH.

Abstract
OBJECTIVES To investigate changes of cognitive performances in female elderly patients with osteoporosis and to determine whether any impairments can be attributed to dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. METHODS This cross-sectional study included 277 postmenopausal women, who were divided into an osteoporosis patients group (n = 170) and an age, gender and educational history matching control group (n = 107). All the subjects completed a set of neuropsychological tests for the elderly for cognitive assessment, which included measures of executive function, episodic memory, attention and processing speed, semantic memory, and visuospatial construction. Blood biomarkers for osteoporosis, as well as diurnal rhythms of cortisol levels were used as cognitive performance correlation parameters in linear multivariate regression analyses. RESULTS Individuals with osteoporosis had poorer cognitive scores (P < 0.001). When dividing the osteoporosis patients according to their Mini-Mental State Examination scores into mild cognitive impairment (MCI) and normal cognitive (NC) performance groups, Auditory Verbal Learning trial 1-5 scores were lower (P = 0.006) and Trail Making Test-A scores were higher (P = 0.05) in the MCI compared to the NC group. Further comparison of the MCI and NC groups revealed that declarative memory was inversely associated with cortisol levels (P < 0.001), but this association became marginal when 25-hydroxy vitamin D was included in the linear multivariate regression analyses (P = 0.06). CONCLUSIONS Patients with osteoporosis are prone to cognitive impairments especially declarative memory deficits. The cognitive impairment may be the result of HPA axis dysregulation but 25-hydroxy vitamin D serum concentrations might be compensatory or even a potent contributing factor.

Abstract
In recent years, the condition of subclinical hypercortisolism (SH) has become a topic of growing interest. This is due to the fact that SH prevalence is not negligible (0.8-2% in the general population) and that, although asymptomatic, this subtle cortisol excess is not harmless, being associated with an increased risk of complications, in particular of osteoporosis and fragility fractures. As specific symptoms of hypercortisolism are absent in SH, the SH diagnosis relies only on biochemical tests and it is a challenge for physicians. As a consequence, even the indications for the evaluation of bone involvement in SH patients are debatable and guidelines are not available. Finally, the relative importance of bone density, bone quality and glucocorticoid sensitivity in SH is a recent field of research. On the other hand, SH prevalence seems to be increased in osteoporotic patients, in whom a vertebral fracture may be the presenting symptom of an otherwise asymptomatic cortisol excess. Therefore, the issue of who and how to screen for SH among the osteoporotic patients is widely debated. The present review will summarize the available data regarding the bone turnover, bone mineral density, bone quality and risk of fracture in patients with endogenous SH. In addition, the role of the individual glucocorticoid sensitivity in SH-related bone damage and the problem of diagnosing and managing the bone consequences of SH will be reviewed. Finally, the issue of suspecting and screening for SH patients with apparent primary osteoporosis will be addressed.

Abstract
This report describes the presence of lower extremity insufficiency fractures in 10 women prior to the clinical and biochemical diagnosis of endogenous Cushing's syndrome (CS). Osteoporosis is a well-recognized complication of overt CS resulting in a high rate of vertebral and other fractures. After institutional review board (IRB) approval, we did a retrospective chart review of patients with lower extremity (LE) insufficiency fractures (IF) and CS. This chart review found 10 women in whom LE-IF preceded the diagnosis of endogenous CS. Low bone density was found in all but one patient. The CS was considered to be mild (or subclinical) in five patients. LE-IF should be considered part of the skeletal spectrum of CS. Physicians caring for patients with LE-IF should have a low threshold for the consideration of CS even in patients without overt physical evidence of cortisol excess.

Abstract
The aim of the present study was to investigate the changes in the serum Dickkopf-1 (DKK-1) and tartrate-resistant acid phosphatase 5b (TRACP-5b) levels in preschoolers with nephrotic syndrome (NS). A total of 50 preschoolers (3-5 years old) with NS and 20 healthy preschoolers (control group) were enrolled in the prospective single-center study. The patients with NS received glucocorticoid treatment and the control group received no treatment. The levels of serum calcium, phosphorus, TRACP-5b, DKK-1 and 25-hydroxyvitamin D3 were measured at baseline and at 3 and 6 months in all the subjects. The levels of DKK-1 and TRACP-5b were significantly higher in the NS group prior to treatment when compared to the control group (P<0.05), but did not differ significantly between the two groups following treatment (P>0.05). Therefore, DKK-1 and TRACP-5b can be used as biomarkers of bone formation and bone resorption, respectively, in the early evaluation of bone metabolism.

Abstract
OBJECTIVE Subclinical hypercortisolism (SH) is associated with increased risk of vertebral fractures (VFx). The effect on bone following recovery from SH is unknown. DESIGN Of the 605 subjects consecutively referred for monolateral adrenal incidentalomas (AIs) to our outpatient clinics, 55 SH patients (recruited on the basis of the exclusion criteria) were enrolled. We suggested to all patients to undergo adrenalectomy, which was accepted by 32 patients (surgical group, age 61.3±8.1 years) and refused by 23 patients, who were followed with a conservative management (non-surgical group, age 65.4±7.1 years). METHODS We diagnosed SH in patients with serum cortisol after 1 mg dexamethasone suppression test (1 mg-DST) >5.0 μg/dl or with greater than or equal to two criteria among 1 mg-DST >3.0 μg/dl, urinary free cortisol >70 μg/24 h and ACTH <10 pg/ml. We assessed: bone mineral density (BMD) at lumbar spine (LS) and femoral neck (as Z-score) by dual-energy X-ray absorptiometry and the VFx presence by X-ray at baseline and at the end of follow up (surgical group 39.9±20.9 months and non-surgical group 27.7±11.1 months). RESULTS The LS Z-score (ΔZ-score/year) tended to increase in the surgical group (0.10±0.20) compared with the non-surgical group (-0.01±0.27, P=0.08) and in the former, the percentage of patients with new VFx was lower (9.4%) than in the latter (52.2%, P<0.0001). Surgery in AI patients with SH was associated with a 30% VFx risk reduction (odds ratio 0.7, 95% CI 0.01-0.05, P=0.008) regardless of age, gender, follow up duration, 1 mg-DST, LS BMD, and presence of VFx at baseline. CONCLUSION In patients with monolateral AI and SH, adrenalectomy reduces the risk of VFx.

Abstract
Osteoporosis is a systemic disease characterized by bone mass and density loss leading to fragility fractures. Osteoporosis due to endocrine disorders is an example of secondary osteoporosis. The harmful effects on bones are common in patients harboring pituitary tumors (acromegaly, prolactinoma, Cushing's disease) and suffering from hypopituitarism. Increased fracture risk and high healthcare costs of fractured patients are their consequences. The coexistence of some of these disorders and hypogonadism results in severe osteoporosis. The influence of the certain diseases, their activity and therapy and accompanying hypogonadism on bone turnover, bone mineral density and fracture incidence is presented.

Effects of up to 15 years of recombinant human GH (rhGH) replacement on bone metabolism in adults with growth hormone deficiency (GHD): the Leiden Cohort Study. Clin Endocrinol (Oxf) 2014; 81:727-35. [PMID: 24816144 DOI: 10.1111/cen.12493] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2014] [Revised: 04/11/2014] [Accepted: 05/01/2014] [Indexed: 12/01/2022]
Abstract
BACKGROUND Growth hormone deficiency (GHD) in adulthood may be associated with a decreased bone mineral density (BMD), a decreased bone mineral content (BMC) and an increased fracture risk. Recombinant human GH (rhGH) replacement induces a progressive increase in BMD for up to 5-7 years of treatment. Data on longer follow-up are, however, scarce. METHODS Two hundred and thirty-adult GHD patients (mean age 47·1 years, 52·6% female), of whom 88% patients had adult-onset (AO) GHD, receiving rhGH replacement for ≥5 years were included in the study. Most patients had multiple pituitary hormone deficiencies. Bone turnover markers, BMC and BMD and T-scores at the lumbar spine and femoral neck were evaluated at baseline, and after 5, 10 and 15 years of rhGH replacement. In addition, clinical fracture incidence was assessed. RESULTS Mean lumbar spine BMD, lumbar spine BMC and T-scores gradually increased during the first 10 years of rhGH replacement and remained stable thereafter. Largest effects of rhGH supplementation were found in men. In the small subset of patients using bisphosphonates, use of bisphosphonates did not impact additional beneficial effects in the long term. Low baseline BMD positively affected the change in BMD and BMC over time, but there was a negative effect of high GH dose at 1 year on the change in BMD and BMC over time. Clinical fracture incidence during long-term rhGH replacement was 20.1/1000 py. CONCLUSIONS Fifteen years of rhGH replacement in GHD adults resulted in a sustained increase in BMD values at the lumbar spine, particularly in men, and stabilization of BMD values at the femoral neck. Clinical fracture incidence was suggested not to be increased during long-term rhGH replacement.

Abstract
PURPOSE Fracture risk data following curative treatment of Cushing's syndrome (CS) are scarce and the role of bisphosphonates in bone recovery after remission is controversial. We evaluated the effects of hypercortisolism remission in bone recovery in CS. Then, we assessed if the FRAX(®) algorithm calculated before the cure can predict fracture risk after cure. METHODS Thirty-six patients with CS were retrospectively investigated. Bone turnover markers, bone mineral density (BMD) at the lumbar spine (L1-L4) and left femur (both neck and total hip were considered), and fracture risk using FRAX(®) algorithm with femoral neck BMD were evaluated at diagnosis and after a median follow-up of 24 months (range 12-108 months) from hypercortisolism remission. Data about bone active therapy were analyzed. RESULTS Hypercortisolism remission was associated with the improvement of all densitometric parameters and with the reduction of fracture risk. The percentage change in BMD and the fracture risk were not significantly different in bisphosphonate-treated vs. untreated patients. During follow-up, three fractured patients at baseline exhibited a new vertebral fracture. A baseline 10-year probability of major osteoporotic fractures (FRAX(®) Major) of 17 % was able to predict the occurrence of a new vertebral fracture during follow-up after cure with 100 % sensitivity, 77 % specificity, 81 % positive predictive value and 100 % negative predictive value. CONCLUSIONS Osteoporosis and fracture risk may be reversible after curative treatment of CS, regardless of bisphosphonate therapy. We suggest applying the FRAX(®) algorithm to all active CS patients using a baseline FRAX(®) Major of 17 % as "intervention threshold".

Abstract
It was assumed that resolution of hypercortisolism in Cushing syndrome (CS) was followed by normalization of morbidity; however, in the last decade evidence is accumulating that patients with cured CS still have increased morbidity and mortality after the biochemical control of hypercortisolism. Patients with CS have an increased cardiovascular and metabolic risk and persistent accumulation of central fat, with an unfavorable adipokine profile, not only during the active phase of the disease but also long after biochemical remission. Clinical management should be particularly careful in identifying global cardiovascular risk, as a primary goal during the followup of these patients, aimed at improving global vascular morbidity. Moreover bone mass is reduced not only due to the endogenous hypercortisolism but also due to duration and dose of exogenous glucocorticoid (GC) replacement therapy after surgery. Thus, therapy in operated patients with inhibition of the hypothalamic-pituitary-adrenal axis should be reduced to the lowest dose and duration possible. Specific treatments should be considered in patients with decreased bone mass, aimed at reducing the increased fracture incidence. Finally, cognitive and health related quality of life impairments, described in active disease, are still abnormal after endocrine cure. Thus, residual morbidity persists in cured CS, suggesting irreversibility of GC-induced phenomena, typical of chronic hypercortisolism.

Abstract
SUMMARY This is the first study examining the impact of both clinical, biochemical, and genetic determinants in the occurrence of bone complications in patients with overt Cushing's syndrome (CS). It demonstrates that the degree and duration of hypercortisolism seem to play a major role in bone loss and fractures development in these patients. INTRODUCTION Bone loss and fractures are a common complication of CS. We investigate the role of gender, disease etiology, duration, and degree of hypercortisolism as well as the impact of glucocorticoid receptor (GR) polymorphisms on the development of bone complications in CS. METHODS Fifty-two patients with active CS (38 Cushing's disease and 14 with cortisol-secreting adrenal adenoma) were genotyped for GR polymorphisms (BclI, N363S, ER22/23EK, and A3669G). In all patients, clinical, hormonal, and biochemical markers of bone turnover, densitometric parameters [lumbar spine and left femur bone mineral density (BMD), T-score, Z-score] as well as the prevalence of bone demineralization and both vertebral and peripheral fractures were assessed. RESULTS No differences were found in bone complications according to gender, disease etiology, and genetic variants distribution. Fractured patients compared to non-fractured ones showed increased levels of urinary free cortisol (UFC) and a more compromised densitometric profile. UFC levels correlated with the occurrence of vertebral fractures (r = 0.43, p = 0.009) while midnight serum cortisol correlated with L1-L4 BMD values (r = -0.35, p = 0.04). Disease duration correlated with the presence of peripheral fractures (r = 0.36, p = 0.04). CONCLUSIONS While GR gene variants as well as gender and disease etiology seem not to play a role, the degree and duration of hypercortisolism seem to be the major determinants of bone loss and fractures in this group of patients. More investigations are needed to understand the real impact of these determinants on the development of bone complications in patients with hypercortisolism.

Abstract
Guidelines for the management of osteoporosis induced by endogenous hypercortisolism are not available. Both the American College of Rheumatology and the International Osteoporosis Foundation recommend to modulate the treatment of exogenous glucocorticoid-induced osteoporosis (GIO) based on the individual fracture risk profile (calculated by FRAX) and dose of glucocorticoid used, but it is difficult to translate corticosteroid dosages to different degrees of endogenous hypercortisolism, and there are no data on validation of FRAX stratification method in patients with endogenous hypercortisolism. Consequently, it is unclear whether such recommendations may be adapted to patients with endogenous hypercortisolism. Moreover, patients with exogenous GIO take glucocorticoids since suffering a disease that commonly affects bone. On the other hand, the correction of coexistent risk factors, which may contribute to increase the fracture risk in patients exposed to glucocorticoid excess, and the removal of the cause of endogenous hypercortisolism, may lead to the recovery of bone health. Although the correction of hypercortisolism and of possible coexistent risk factors is necessary to favor the normalization of bone turnover with recovery of bone mass; in some patients, the fracture risk could not be normalized and specific anti-osteoporotic drugs should be given. Who, when, and how the patient with endogenous hypercortisolism should be treated with bone-active therapy is discussed.

Abstract
Osteoporosis and bone fractures are commonly seen in patients with Cushing's syndrome (CS). Fractures usually occur in the vertebrae and ribs whereas pubic fractures are less common. Similar to obvious hypercortisolemia, subclinical hypercortisolemia can increase the risk of fractures. However, in subclinical cases, bone fractures are very rarely seen as the presenting symptom. We herein report the case of a 62-year-old postmenopausal woman who was presented with a pubic fracture. During the evaluation of the fracture, thoracoabdominal magnetic resonance imaging of the patient demonstrated an adrenal mass. Although the patient did not show any signs of overt hypercortisolism, an endocrinologic evaluation revealed hypercortisolism due to an adrenal tumor. Adrenalectomy was performed, which resulted in a cure of the disease. During the orthopedic follow-up, the patient's pubic area pain gradually improved, and the pubic fracture healed without any accompanying new bone fractures. One year after the surgery, a remarkable improvement was detected in the patient's bone density in spite of the lack of administration of any medications for osteoporosis. Subclinical CS can present as a pubic fracture, and awareness of this relationship can help physicians to diagnose the disease.

Abstract
BACKGROUND Psychologic stress and clinical hypercortisolism have been related to direct effects on bone metabolism. However, there is a lack of information regarding the outcomes of regenerative approaches under the influence of chronic stress (CS). Enamel matrix derivative (EMD) has been used in periodontal regenerative procedures, resulting in improvement of clinical parameters. Thus, the aim of this histomorphometric study is to evaluate the healing of periodontal defects after treatment with EMD under the influence of CS in the rat model. METHODS Twenty Wistar rats were randomly assigned to two groups; G1: CS (restraint stress for 12 hours/day) (n = 10), and G2: not exposed to CS (n = 10). Fifteen days after initiation of CS, fenestration defects were created at the buccal aspect of the first mandibular molar of all animals from both groups. After the surgeries, the defects of each animal were randomly assigned to two subgroups: non-treated control and treated with EMD. The animals were euthanized 21 days later. RESULTS G1 showed less bone density (BD) compared to G2. EMD provided an increased defect fill (DF) in G1 and higher BD and new cementum formation (NCF) in both groups. The number of tartrate-resistant acid phosphatase-positive osteoclasts was significantly higher in G1 when compared to G2 and in EMD-treated sites of both groups. CONCLUSIONS CS may produce a significant detrimental effect on BD. EMD may provide greater DF compared to non-treated control in the presence of CS and increased BD and NCF in the presence or absence of CS.

Abstract
This study investigated the effects of exposure to the ubiquitous contaminants polychlorinated biphenyls (PCBs) on the fetal adrenal cortex and on plasma cortisol using the domestic sheep (Ovis aries) as a model. Pregnant ewes were intendedly subjected to oral treatment with PCB 153 (98 μg/kg bw/day), PCB 118 (49 μg/kg bw/day) or the vehicle corn oil from mating until euthanasia on gestation day 134 (±0.25 SE). However, because of accidental cross-contamination occurring twice causing a mixed exposure scenario in all three groups, the focus of this paper is to compare three distinct groups of fetuses with different adipose tissue PCB levels (PCB 153high, PCB 118high and low, combined groups) rather than comparing animals exposed to single PCB congeners to those of a control group. When comparing endocrine and anatomical parameters from fetuses in the PCB 153high (n = 13) or PCB 118high (n = 14) groups with the low, combined group (n = 14), there was a significant decrease in fetal body weight (P < 0.05), plasma cortisol concentration (P < 0.001) and adrenal cortex thickness (P < 0.001). Furthermore, adrenal weight was decreased and plasma ACTH was increased only in the PCB 118high group. Expression of several genes encoding enzymes and receptors related to steroid hormone synthesis was also affected and mostly down-regulated in fetuses with high PCB tissue levels. In conclusion, we suggest that mono-and di-ortho PCBs were able to interfere with growth, adrenal development and cortisol production in the fetal sheep model. © 2011 Wiley Periodicals, Inc.

Abstract
Patients with adrenal incidentalomas (AIs) and subclinical hypercortisolism (SH) have increased risk of fracture independent of bone mineral density (BMD) and possibly due to reduced bone quality. The trabecular bone score (TBS) has been proposed as a index of bone microarchitecture. The aim of the study was to investigate TBS in AI. In 102 AI patients, SH was diagnosed in the presence of at least two of the following: (1) urinary free cortisol >70 µg/24 h (193.1 nmol/L); (2) cortisol after 1-mg dexamethasone suppression test (1-mg DST) >3.0 µg/dL (82.8 nmol/L); or (3) adrenocorticotropic hormone (ACTH) <10 pg/mL (<2.2 pmol/L). In patients and in 70 matched controls, BMD was measured at lumbar spine (LS) and femur (neck [FN] and total [FT]) by dual X-ray absorptiometry and TBS was assessed in the region of LS-BMD; BMD and TBS data were reported as Z-scores. In patients, vertebral deformities were assessed by radiograph. Patients with SH (n = 34) had lower LS-BMD (-0.31 ± 1.17), FT-BMD (-0.29 ± 0.91), and TBS (-3.18 ± 1.21) than patients without SH (n = 68, 0.31 ± 1.42, p = 0.03; 0.19 ± 0.97, p = 0.01; -1.70 ± 1.54, p < 0.0001, respectively) and controls (0.42 ± 1.52, p = 0.02; 0.14 ± 0.76, p = 0.02; -1.19 ± 0.99, p < 0.0001, respectively). TBS was inversely correlated with 1-mg DST (β = -0.26, t = -2.79, p = 0.006) regardless of age, LS-BMD, body mass index (BMI), and gender. The presence of fracture was associated with low TBS alone (odds ratio [OR], 4.8; 95% confidence interval [CI], 1.85-12.42, p = 0.001) and with the cluster low TBS plus low LS-BMD (OR, 4.37; 95% CI, 1.71-11.4, p = 0.002), after adjustment for age, BMI, and gender. Low TBS plus low LS-BMD showed a good specificity (79%) for predicting fractures, whereas normal TBS (ie, > -1.5) plus normal LS-BMD high specificity (88.1%) for excluding fractures. Finally, TBS predicted the occurrence of a new fracture in 40 patients followed for 24 months (OR, 11.2; 95%CI, 1.71-71.41, p = 0.012) regardless of LS-BMD, BMI, and age. In SH, bone quality, as measured by TBS, is altered. TBS is useful in detecting AI patients at risk of fractures.

Abstract
Long-term corticosteroid treatment is the most common secondary cause of bone loss. Patients treated with long-term corticosteroid therapy may develop osteopenia or osteoporosis, and many have fractures. It is difficult to predict which corticosteroid-treated patients will develop significant skeletal complications because of variability in the underlying diseases treated with corticosteroids, and because of variation in corticosteroid dose over time. Corticosteroid therapy causes an alteration in the ratio between osteoprotegerin (OPG) and receptor activator of nuclear factor κ B (RANK) ligand (RANKL), which leads to early increased bone resorption for the first 3-6 months, with long-term treatment leading primarily to suppression of bone formation. Recently published recommendations advise the use of bisphosphonates or teriparatide in high-risk patients, depending on fracture risk assessed by bone mineral density testing. This article gives an update of current knowledge regarding the pathophysiology, clinical presentation and evaluation, and prevention and treatment of patients with corticosteroid-induced osteoporosis.

Abstract
Cushing's syndrome (CS) is a clinical condition resulting from chronic exposure to glucocorticoid excess. As a consequence, hypercortisolism contributes significantly to the early development of systemic disorders by direct and/or indirect effects. Complications such as obesity, hypertension, diabetes, dyslipidemia, and hypercoagulability cause premature atherosclerosis and increase cardiovascular mortality. Impairment of the skeletal system is a relevant cause of morbidity and disability in these patients especially due to the high prevalence of vertebral fractures. In addition, muscle weakness, emotional lability, depression, and impairment of quality of life are very common. Clinical management of these patients is complex and should be particularly careful in identifying global cardiovascular risks and aim at controlling all complications. Although the primary goal in the prevention and treatment of complications is the correction of hypercortisolism, treatment does not completely eliminate these comorbidities. Given that cardiovascular risk and fracture risk can persist after cure, early detection of each morbidity could prevent the development of irreversible damage. In this review we present the various complications of CS and their pathogenetic mechanisms. We also suggest the clinical management of these patients based on our extensive clinical experience and on the available literature.

Abstract
OBJECTIVE The European Registry on Cushing's syndrome (ERCUSYN) is designed to collect prospective and follow-up data at EU level on Cushing's syndrome (CS). DESIGN AND METHODS Baseline data on 481 CS patients (390 females, 91 males; mean age (±s.d.): 44±14 years) collected from 36 centres in 23 countries, including new patients from 2008 and retrospective cases since 2000. Patients were divided into four major aetiologic groups: pituitary-dependent CS (PIT-CS) (66%), adrenal-dependent CS (ADR-CS) (27%), CS from an ectopic source (ECT-CS) (5%) and CS from other aetiologies (2%). RESULTS Proportion of men in the ECT-CS group was higher than in the other groups (P<0.05). The ADR-CS group was older than the PIT-CS (P<0.05). Prevalence of hirsutism (92%) and diabetes (74%) in ECT-CS was higher than in the other groups (P<0.05 and P<0.01 respectively). PIT-CS had more skin alterations, menstrual irregularities and hirsutism than ADR-CS (P<0.01). Reduced libido was more prevalent in men than women (P<0.01). Prevalence of spine osteoporosis was higher in men than women (P<0.05), and males had more vertebral and rib fractures than females (52 vs 18% for vertebrae; P<0.001 and 34 vs 23% for ribs; P<0.05). ECT-CS consulted a diabetologist more frequently than ADR-CS (P<0.05), while a gynaecologist was consulted more often by women with PIT-CS or ADR-CS than with ECT-CS (P<0.05). Overall, weight gain was more common in women than men (P<0.01). CushingQoL and EuroQoL visual analogue scale scores did not differ between the groups. CONCLUSIONS The ERCUSYN project demonstrates a heterogeneous clinical presentation of CS at a European level, depending on gender and aetiology.

Abstract
In patients with adrenal incidentalomas (AIs), cross-sectional studies suggested the presence of an association between subclinical hypercortisolism (SH) and an increased prevalence of vertebral fractures (VFx) and spinal deformity index (SDI), which is a clinical index of bone quality. No longitudinal studies investigated the incidence of VFx and SDI changes over time in SH. The aim of this study was to evaluate VFx risk and SDI changes in SH over time. One-hundred-three consecutive AI patients were studied at baseline and after 12 and 24 months. Patients were divided into SH(+) (n = 27) and SH(-) (n = 76) groups on the basis of the presence of two or more among urinary free cortisol greater than 70 µg/24 hours, serum cortisol after 1-mg dexamethasone suppression test greater than 3.0 µg/dL, and adrenocorticotropic hormone (ACTH) less than 10 pg/mL in 2 or more of the 3 evaluations. At baseline and after 24 months, bone mineral density (BMD) by dual-energy X-ray absorptiometry and the presence of VFx and SDI by summing the grade of deformity for each vertebra were evaluated. At the end of follow-up, the SH(+) group showed a higher prevalence of VFx (81.5%) as compared with baseline (55.6%, p = .04) and a worsening of SDI (2.11 ± 1.85 versus 1.11 ± 1.47, p = .032) associated with SH regardless of age, gender, body mass index , BMD, baseline SDI, menopause duration [odds ratio (OR) = 12.3, 95% confidence interval (CI) 4.1-36.5, p = .001]. The incidence of new vertebral fractures was higher in the SH(+) group (48%) than in the SH(-) group (13%; p = .001). It is concluded that subclinical hypercortisolism is associated with an increased risk of VFx and a possible deterioration of bone quality.

Abstract
BACKGROUND The term adrenal incidentaloma (AI) indicates an adrenal mass lesion > 1 cm in diameter discovered during testing for conditions unrelated to adrenal disease. The overall prevalence of these lesions ranges between 3% and 10%. Their incidence increases with age, and it is clinically important to identify AI associated with hormonal activity and/or malignant potential. DESIGN A detailed Medline search of all English language articles related to AI was carried out, and the clinical implications related to their hormonal activity and malignant potential are discussed. RESULTS The subclinical hypercortisolism observed in a significant percentage of patients with AI is associated with some of the detrimental effects of continuous autonomous cortisol secretion, including a higher prevalence of hypertension, dyslipidaemia, impaired glucose tolerance or type 2 diabetes mellitus and an increased risk for osteoporotic fractures. However, it remains to be proven whether treatment to reverse subtle glucocorticoid excess is beneficial. Clinically silent phaeochromocytomas and primary adrenal cancer are conditions associated with significantly high morbidity and mortality and require urgent treatment, while the prevalence and clinical significance of autonomous mineralocorticoid secretion are less clearly defined. Size and radiological features are the main predictors of malignant potential. CONCLUSIONS Patients harbouring AI should be evaluated for the possibility of malignancy and/or subclinical hypercortisolism which is associated with cardiovascular risk and bone loss. However, in the absence of prospective controlled studies correlating biochemical activity with end-organ complications, the long-term consequences of AI remain uncertain and their management remains largely pragmatic.

Abstract
A 22-year-old G(1)P(0) was admitted at 26 weeks gestation for preeclampsia, hyperglycaemia and cushingoid features. Elevated 24-h urine free cortisol (UFC) and suppressed plasma adrenocorticotrophic hormone (ACTH) suggested ACTH-independent Cushing's syndrome. Ultrasound showed left adrenal mass. She delivered preterm at 28 weeks due to severe preeclampsia and fetal distress. The infant expired after 4 days. Blood pressure was controlled after delivery and the patient was discharged on ketoconazole. Adrenalectomy was planned postpartum; however, she withdrew consent and was lost to follow-up. A 33-year-old G(1)P(1) presented with gestational diabetes. Pregnancy was complicated by premature delivery at 31 weeks for fetal distress. The baby improved and survived. Three months postpartum, she was evaluated for osteoporosis after sustaining a fracture from a fall. Cushingoid facies, elevated 24-h UFC, suppressed ACTH and a right adrenal mass on MRI confirmed an ACTH-independent Cushing's syndrome. She underwent adrenalectomy and improved.

Abstract
BACKGROUND Cortisol within the normal range has been associated with reduced bone density in the elderly, but little is known about this relationship in healthy young women. PURPOSE The purpose of this study is to assess whether 24-h urinary free cortisol excretion (UFC) is related to bone density in 132 healthy, non-obese, regularly menstruating women, aged 19-35. METHOD Participants completed questionnaires (food frequency, demographics, physical activity, dietary restraint, perceived stress, and daily stress) and a 24-h urine collection. UFC was determined by high-throughput liquid chromatography and tandem mass spectrometry. Anthropometrics were completed and a dual energy X-ray absorptiometry scan measured areal bone mineral density (aBMD, g/cm(2)) and bone mineral content (BMC, g) at the lumbar spine (L1-4), hip, and total body (TB) as well as total body lean (LBM) and fat mass. RESULTS aBMD and BMC were significantly positively associated with height, LBM, physical activity, calcium intake, and duration of previous oral contraceptive use (except L1-4) and negatively with perceived stress. UFC was not correlated with any measured variables except urine volume (r = 0.17, p = 0.046). After adjusting for urine volume, height, LBM, ethnicity, and prior oral contraceptive use, UFC was significantly inversely associated with TB BMC (r = -0.30, p < 0.001) and aBMD (r = -0.27, p = 0.003), L1-4 aBMD (r = -0.19, p = 0.035) and BMC (r = -0.18, p = 0.049), and hip BMC (r = -0.23, p = 0.011). Further adjustment for sport activity, calcium intake and perceived stress did not change these relationships meaningfully except that L1-4 became nonsignificant (p < 0.07). CONCLUSION Cortisol within the normal range appears to have a minor negative influence on bone density in healthy young women.

Abstract
The elderly population is at risk for polypharmacy and, therefore, also at risk for drug-induced osteoporosis (DIOP). Epidemiologic studies provide valuable information about medications that may place patients at risk for DIOP. While glucocorticoids are the most common cause of DIOP, the use of several other therapeutic agents can place patients at risk for significant bone loss and fracture. These medications include, but are not limited to, aromatase inhibitors, gonadotropin-releasing hormone agonists, thyroid replacement therapy, antiepileptics, antidepressants, antipsychotics, lithium, gastric acid lowering agents, thiazolidinediones, loop diuretics, heparins and warfarin, vitamin A and cyclosporine. This article provides information about their mechanism of action, studies that have evaluated these agents in DIOP and prevention and treatment strategies.

Abstract
CONTEXT Cross-sectional studies have found associations among elevated cognitive dietary restraint (CDR), increased ovulatory disturbances, and lower bone mass, possibly mediated by cortisol. OBJECTIVE To determine whether healthy young women with higher CDR have more menstrual cycles with subclinical ovulatory disturbances (SOD), elevated 24-h urinary free cortisol (UFC), and less positive 2-yr areal bone mineral density change (Delta-aBMD). DESIGN, SETTING, AND PARTICIPANTS We conducted a 2-yr longitudinal study of 123 healthy, community-dwelling, nonobese, regularly menstruating women aged 19-35 yr. MAIN OUTCOME MEASURES Key variables were Three Factor Eating Questionnaire Restraint score, percent of cycles with anvoluation and/or luteal phase length <10 d (%SOD), UFC, and Delta-aBMD at the lumbar spine (L1-L4), total hip, and whole body. Anthropometrics, general stress, physical activity, and energy intake were measured. Adjusting for potential confounders, differences were examined by general linear modeling using median split of CDR score and %SOD. RESULTS Women with higher CDR had higher %SOD (56 vs. 34%, P < 0.001) and higher UFC (28.0 vs. 24.0 microg/d, P = 0.021). Delta-aBMD did not differ by CDR. Women with higher %SOD had less positive Delta-aBMD at L1-L4 (0.7 vs. 1.9%, P = 0.034) and hip (-0.6 vs. 0.9%, P = 0.001), and higher CDR score (8.7 vs. 7.1, P = 0.04). Physical activity, general stress, body mass index, and energy intake did not explain differences by CDR or %SOD. UFC was not associated with %SOD or Delta-aBMD. CONCLUSION Women with more frequent SOD reported higher CDR and experienced less positive Delta-aBMD. Although women with higher CDR had higher UFC, the mechanism linking CDR, SOD, and aBMD is not clear.

Abstract
UNLABELLED We investigated bone turnover and its restoration in a large number of patients in the active phase and after cure of endogenous Cushing's syndrome. Furthermore, the usefulness of serum osteocalcin and collagen breakdown products as potential markers of active Cushing's syndrome was also evaluated. INTRODUCTION Suppressed bone formation is one of the most characteristic features of Cushing's syndrome (CS). Despite numerous previous reports, many aspects of the disturbed bone metabolism of these patients are unexplored. In this study, we investigated the time course of bone marker changes after the cure of CS as well as correlations between bone markers and serum cortisol concentrations. METHODS Eighty-seven patients with CS were studied. Patients were followed up to 48 months after surgical cure. Serum osteocalcin (OC) and collagen breakdown products (CTX) were measured with immunochemiluminescence method and compared to the results of 161 healthy controls. RESULTS OC showed a negative, while CTX displayed a positive correlation with serum cortisol. Patients with diabetes mellitus and myopathy had significantly lower serum OC levels compared to those without these complications. The area under the curve of OC obtained by receiver-operating characteristics analysis for the discrimination of patients with CS from healthy controls was 0.9227. Postoperative OC increased rapidly from the first few days or weeks reaching its maximum at the sixth month and remained stable after the 24th postoperative month. CONCLUSIONS Our study demonstrated significant correlations between serum cortisol and both bone formation and resorption markers in the active phase of CS. We propose that OC may serve as a sensitive biologic marker of glucocorticoid activity in endogenous CS during its active phase and it may reflect the clinical cure of the disease.

Abstract
A number of medical specialities have witnessed a dramatic change in the provision of in patient care over the last decade. Work has moved into outpatient and Day Unit settings and, more recently, into the community. This has led to the amalgamation of speciality based beds with the perceived threat of loss of independence and potential reduction in training opportunities. In reality, our experience of a combined inpatient ward for Rheumatology and Endocrinology patients has been positive, with increased awareness of the coexistence of certain disorders and a resulting enhanced approach to the delivery of patient care, junior doctor education and clinical research. We would like to share our experience by describing some of the overlapping clinical conditions between these specialities that physicians might wish to consider.

Abstract
CONTEXT In patients with adrenal incidentalomas and subclinical hypercortisolism (SH), the factors influencing bone and the prevalence of vertebral fractures are debated. Spinal deformity index (SDI), which reflects bone quality, has never been evaluated. OBJECTIVE The objective of the study was to investigate in these patients SDI and factors influencing the prevalence of fractures. DESIGN This was a retrospective, multicenter study. SETTING The study was conducted on an in- and outpatient basis. PATIENTS Patients included 287 adrenal incidentaloma patients (111 eugonadal males, 31 premenopausal, 145 postmenopausal females) and 194 controls (90 eugonadal males, 29 premenopausal, 75 postmenopausal females). MAIN OUTCOME MEASURE Bone mineral density (BMD) was measured by dual X-ray absorptiometry at lumbar spine and femoral neck. By radiograph each vertebra was assessed as intact (grade 0) or grade 1 (20-25%), 2 (25-40%), or 3 (>40%) deformity; SDI was calculated by summing the grade of deformity for each vertebra. SH was diagnosed in the presence of at least two of the following: urinary free cortisol greater than 70 microg per 24 h (193.1 nmol/liter), cortisol after 1-mg dexamethasone test greater than 3.0 microg/dl (>82.8 nmol/liter), ACTH less than 10 pg/ml (<2.2 pmol/liter). RESULTS BMD was significantly lower in SH+ than SH- patients and controls (lumbar spine -0.73 +/- 1.43, 0.17 +/- 1.33, 0.12 +/- 1.21, respectively; femoral neck -0.37 +/- 1.06, 0.07 +/- 1.09, 0.17 +/- 1.02). Patients with SH had higher fracture prevalence and SDI than those without SH and controls (70.6, 22.2, 21.8%, respectively, P < 0.0001; 0.31 +/- 0.68, 0.39 +/- 0.93, 1.35 +/- 1.27, respectively, P < 0.0001). Fractures and SDI were associated with SH (odds ratio 7.27, 95% confidence interval 3.94-13.41, P = 0.0001; beta = 0.352, t = 6.241, P = 0.0001, respectively) regardless of age, BMD, menopause, and gender. CONCLUSION SH is associated with low BMD, high fracture prevalence, and reduced bone quality as measured by SDI.

Abstract
The secondary occurrence of type 2 diabetes with various hormonal diseases (e.g. pituitary, adrenal and/or thyroid diseases) is a recurrent observation. Indeed, impaired glucose tolerance (IGT) and overt diabetes mellitus are frequently associated with acromegaly and hypercortisolism (Cushing syndrome). The increased cardiovascular morbidity and mortality associated with acromegaly and Cushing syndrome may partly be a consequence of increased insulin resistance that normally accompanies hormone excess. Acromegalic patients are insulin resistant, both in the liver and in the periphery, displaying hyperinsulinemia and increased glucose turnover in the basal post-absorptive states. The prevalence of diabetes mellitus and that of IGT in acromegaly is reported to range 16-56%, whereas the degree of glucose tolerance seems correlated with circulating growth hormone (GH) levels, age, and disease duration. Moreover, a family history of diabetes and concomitant presence of arterial hypertension have been found to predispose to diabetes as well. GH has physiological effects on glucose metabolism, stimulating gluconeogenesis and lipolysis, which results in increased blood glucose and free fatty acid levels. Conversely, insulin-like growth factor 1 (IGF-I) enhances insulin sensitivity primarily on skeletal muscles. However, in acromegaly, increased IGF-I levels are unable to counteract the insulin-resistance status determined by GH excess. Therapy with somatostatin analogues (SSAs) induce control of GH and IGF-I excess in the majority of patients, but their inhibitory effect on pancreatic insulin secretion might complicate the overall effect of this treatment on glucose tolerance. Hypercortisolism produces visceral obesity, insulin resistance, and dyslipidemia that together with hypertension, hypercoagulability, and ventricular morphologic and functional abnormalities increase cardiovascular risk, and persist up to 5 years after resolution of hypercortisolism. Hypercortisolism leads to hyperglycaemia and reduced glucose tolerance, determines insulin resistance, stimulates hepatic gluconeogenesis and glicogenolisis. In Cushing syndrome the prevalence of diabetes varies between 20 and 50%, but probably this prevalence is underestimated, as not always an oral glucose tolerance test is performed in the presence of an apparently normal fasting glycaemia. Again, disease duration, rather than hormone levels, seems to be the major determinant in the occurrence of systemic complications in Cushing syndrome. Due to the impact they have on mortality and morbidity in both acromegaly and Cushing syndrome, these complications should be treated aggressively. In patients with neuroendocrine tumours (NETs) the occurrence of altered glucose tolerance may be due to a decreased insulin secretion, like it happens in patients who underwent pancreatic surgery and in those with pheochromocytoma, or to an altered counterbalance between hormones, such as in patients with glucagonoma and somatostatinoma. Moreover, SSAs represent a valid therapeutic choice in the symptomatic treatment of NETs, and also in this case the medical therapy of the primary disease, may have a significant impact on the prevalence of glucose metabolism imbalance. In thyroid disorders, an abnormal glucose tolerance may be principally encountered in hyperthyroidism. The pathogenesis is complex and scant data on prevalence and severity are found in the literature. Adequate treatment for glucose imbalance is mandatory in these peculiar patients in line with the American Diabetes Association and the European Association for the Study of Diabetes consensus statement. In particular, since traditional insulins have two features that may complicate therapy (absorption profiles, delayed onset of action and peak activity), the new insulin analogues could be of particular interest in the management of the secondary diabetes associated with endocrinopathies, considering the frailty of these patients. Indeed, it has been demonstrated that insulin glargine, given once daily, reduces the risk of hypoglycaemia compared with other formulations, and can facilitate a more aggressive insulin treatment in this class of patients.
