Abstract
BACKGROUND Elderly people are exposed to an increased load of stressful events and neuro-hormonal stimulation is a key finding in metabolic syndrome and its related disorders. AIMS To determine the role of cortisol in elderly subjects, with or without metabolic syndrome (MetS), by means of a national multicentre observational study, AGICO (AGIng and Cortisol). METHODS From 2012 to 2017, the AGICO study enrolled n.339 subjects (aged > 65), after obtaining their informed consent. The investigators assessed a cardio-metabolic panel (including electrocardiogram, carotid ultrasonography and echocardiography), the presence of MetS (on Adult Treatment Panel III criteria), a neurological examination (including brain imaging), and cortisol activity (using a consecutive collection of diurnal and nocturnal urine). RESULTS In the patients presenting with MetS, the standardized diurnal and nocturnal cortisol excretion rates were 210.7 ± 145.5 and 173.7 ± 118.1 (mean ± standard deviation) μg/g creatinine/12 h; in those without MetS, the standardized diurnal and nocturnal cortisol excretion rates were 188.7 ± 92.7 and 144.1 ± 82.3 μg/g creatinine/12 h, respectively (nocturnal urinary cortisol in patients with MetS versus those without MetS p = 0.05, female patients with MetS vs female patients without MetS, p < 0.025). A significant positive correlation was found between the CRP levels and both the diurnal and nocturnal urinary cortisol levels with r = 0.187 (p < 0.025) and r = 0.411 (p < 0.00000001), respectively. DISCUSSION The elderly patients with MetS showed a trend towards increased standardized nocturnal cortisol excretions, with particular regard to the female subjects. CONCLUSION The positive correlation between cortisol excretion and low-grade inflammation suggests a common mechanism driving both hormonal and inflammatory changes.

Abstract
PURPOSE Although most cross-sectional and longitudinal studies of children and adolescents have found a link between short duration of sleep and obesity, the literature related to adults provides a non-consensual framework. The aim of the present study was to examine the association between sleep quality and BMI in a population of caregivers looking after people suffering from dementia, with a view to identifying the moderating role of depressive symptoms in the relationship between sleep problems and BMI. METHODS A total of 117 subjects took part in the study, filling in a Sociodemographic Questionnaire, the Pittsburgh Sleep Quality Index, the Eating behavior Questionnaire and The Center for Epidemiologic Studies-Depression. RESULTS Depressive symptoms were greater in females than in males. The sample was divided into two subgroups based on depressive-symptom scores. Only within the subsample with low depressive symptoms, higher sleep disturbances influenced BMI positively. Within this subsample of participants with low depressive symptoms, the variables that seem to play a pivotal role in explaining a high BMI are: female gender, sleep problems, and diet quality, while within the subsample with high depressive symptoms only the female gender factor was found to influence BMI. CONCLUSIONS Depressive symptoms seem to act as moderators in the relationship between sleep and BMI. They should be evaluated to identify the risk of high BMI, and to differentiate clinical intervention, at least in this population, which experiences the stress of caregiving chronically, though not suffering from clinical eating disorders.

Abstract
UNLABELLED This study analyses the difference in 25OH-vitamin D values between two groups of patients both affected by severe osteoporosis with fragility fractures, but one group has vertebral fractures and the other one has hip fractures. Patients with hip fractures have vitamin D values lower than patients with vertebral fractures. INTRODUCTION The purpose of this study was to evaluate 25OHD levels in patients with fragility vertebral fractures (VF) and hip fractures (HF) and make a comparison between the groups. METHODS In the first group were enrolled ambulatory patients with 3 or more moderate to severe VF; in the second group were enrolled patients hospitalized in the Department of Orthogeriatrics undergoing surgery for HF. For all patients, we collected values of 25OHD and PTH. The group of patients with VF was further subdivided into pre-existing VF or recent VF treated within 30 days with vertebroplasty. RESULTS The sample consists of 180 subjects divided into two groups: 90 with VF and 90 with HF. The average value of 25OHD in the total sample was 13.2 ± 9.6 ng/ml, Vitamin D was significantly lower in the HF group than the VF group (p < 0.001)(VF 18.6 ± 9.7 ng/ml, HF 7.9 ± 5.7 ng/ml). The mean PTH value in the total sample was 67.5 ± 54.9 pg/ml and PTH was significantly higher in the HF group compared to the group with VF (p < 0.001) (VF 55.6 ± 27.2 pg/ml, HF 78.7 ± 70.2 pg/ml). The mean 25OHD value in the recent VF group is 16.0 ± 6.6 ng/ml while in the pre-existing VF group is 19.5 ± 10.4 ng/ml with a statistically significant difference (p < 0.001). CONCLUSIONS Patients of the same age with severe osteoporosis have a lower 25OHD value when the fracture occur at the hip and is recent, probably this is due to the inflammation caused by fracture and/or surgical intervention.

Abstract
The ageing of society is driving an enormous increase in fragility fracture incidence and imposing a massive burden on patients, their families, health systems and societies globally. Disrupting the status quo has therefore become an obligation and a necessity. Initiated by the Fragility Fracture Network (FFN) at a "Presidents' Roundtable" during the 5th FFN Global Congress in 2016 several leading organisations agreed that a global multidisciplinary and multiprofessional collaboration, resulting in a Global Call to Action (CtA), would be the right step forward to improve the care of people presenting with fragility fractures. So far global and regional organisations in geriatrics/internal medicine, orthopaedics, osteoporosis/metabolic bone disease, rehabilitation and rheumatology were contacted as well as national organisations in five highly populated countries (Brazil, China, India, Japan and the United States), resulting in 81societies endorsing the CtA. We call for implementation of a systematic approach to fragility fracture care with the goal of restoring function and preventing subsequent fractures without further delay. There is an urgent need to improve: To address this fragility fracture crisis, the undersigned organisations pledge to intensify their efforts to improve the current management of all fragility fractures, prevent subsequent fractures, and strive to restore functional abilities and quality of life.

Abstract
INTRODUCTION To address the worldwide epidemic of obesity, a sizable literature implicates sleep problems in the onset of obesity in younger populations. However, less is known about how this process may operate among older adults, which is of concern, given demographic shifts that have resulted in a much higher proportion of developed nations around the world reaching late life. METHODS We offer a current review of the literature studying older adults and examining associations between sleep quality and obesity in this population. We consider both subjective and objectively measured sleep as well as both cross-sectional and longitudinal studies offering stronger causal inference. RESULTS We discuss seemingly contradictory literature showing that shorter sleep duration as well as longer sleep duration are associated with obesity risk, then review studies that tested for non-linear relationships and reported a U-shape pattern, suggesting that too much or too little sleep is detrimental. Besides sleep duration, we discuss evidence showing that other forms of sleep dysfunction related to night-time awakenings, REM sleep, slow-wave sleep, and daytime sleepiness, which are indicators of sleep quality, are also linked to obesity. Specific psychological and physiological mediators and moderators, suggesting possible mechanisms whereby sleep problems may affect obesity in older adults, are described. CONCLUSION We conclude by discussing areas, where additional research could help clarify this association, considering such factors as medical comorbidities common in late life, and health-related behaviors that may stem from poor sleep (such as disordered eating behavior). Such insights will have great value for clinical practice. LEVEL OF EVIDENCE Level V, narrative review.

Abstract
OBJECTIVES Bullying is a manifestation of occupational stress and can therefore be considered as a real "organizational pathology." Include the activities of the surgery dedicated to Mobbing, Unit of Occupational Medicine Sant'Andrea Hospital, which began operations in June 2001. METHODS In over ten years of operation (July 2012), the sample, consisting of 50.7% for men and 49.3% women, is heterogeneous in age. The schooling of the sample is medium-high as more than 82% have higher education level. The business sector is the service sector accounted for most (84%) than in industry (9%) and agriculture (2%). RESULTS Of the 1545 patients seen, 1320 completed the diagnostic path, while 225 have stopped. 814 users have been certified for compatibility bullying (63% of cases) with a net reduction of the awards from 2007 onwards. CONCLUSIONS Considerations are expressed about the possible intervention strategies: the presence of dedicated experts at the counters of listening and professionals as the trusted advisor, to which workers in distress can call on for advice and guidance on how to defend itself from, in accordance with the implemented for years at the Ministry of Health, the establishment of such figures as the manager rehability that in other European countries, are scheduled for some time in work organization.

Abstract
Studies with a dopamine agonist (Bromocriptine) and an antagonist (Haloperidol) suggest that elevated sex steroid synthesis such as may be found in the polycystic ovary syndrome (PCO) influence the pituitary lactotrope response to endogenous control mechanisms. A distinction between PCO with occasional elevation of plasma prolactin (PRL) and the galactorrhoea-amenorrhoea syndrome (GA) associated with hyperprolactinaemia can be established on the basis of differences in circulating levels of sex steroids and in the pattern of response to lactotrope cell stimulation. Thus, adrenal androgen synthesis can be strengthened in GA whereas in PCO both pathways, adrenal and ovarian, may be overstimulated. Also blunted PRL response to TRH or dopaminergic blockade is often seen in GA. The use of bromocriptine in patients with PCO and elevated PRL plasma levels has been shown to restore ovulation. The possible implications of dopaminergic mechanisms in the control of LH secretion independent of PRL release are discussed.

Abstract
Osteoporotic hip fracture needs a specific approach and treatment, since elderly patients are at high risk for adverse outcomes after surgery. In particular, delirium often occurs in the peri-operative period, and it is associated with death, hospital-acquired complications, persistent cognitive impairments, poor functional recovery after surgery and increased healthcare costs. The pre-operative assessment of the risk factors for delirium improves the preventive measures. The delirium diagnostic tools should be included in the standard of orthogeriatric cure for hip fracture. Given the increasing complexity of the clinical pictures, we present a review of the available treatment options for delirium in patients with hip fracture. The metabolic pre-operative disorders and the management of co-morbid diseases are specific targets of treatment in order to optimize the outcomes after surgery. In particular, elderly patients with Alzheimer's disease are highly vulnerable to hip fracture and delirium, and they are severely frail with reduced physiologic reserves. An integrated approach combining environmental and pharmacological strategies is useful in the delirium treatment, with a close collaboration between the orthopedic and geriatric team.

Abstract
The metabolic syndrome (MetS) presents an increasing prevalence in elderly people. A significant role in MetS is played by the stress response and cortisol. The hypothalamic-pituitary-adrenal (HPA) axis activity is increased by central (loss of hippocampal glucocorticoid receptors) and peripheral (11β-hydroxysteroid dehydrogenase type 1, 11β-HSD1, hyperactivity) mechanisms. The HPA hyperactivity has been found in chronic diseases affecting the endocrine (abdominal obesity with MetS, type 2 diabetes), cardiovascular (atherosclerosis, essential hypertension), and nervous systems (dementia, depression), in aging. A novel therapeutic approach (11β-HSD1 inhibition) is promising in treating the HPA axis hyperactivity in chronic diseases with MetS. A large-scale national clinical trial (AGICO, AGIng, and COrtisol study) has been proposed by our group to evaluate the role of cortisol and MetS in the main pathologies of aging (vascular and degenerative dementia, cardiovascular diseases, type 2 diabetes, abdominal obesity).

Abstract
The hepatitis C virus (HCV) infection is an important public health problem and it is associated with hepatic and extrahepatic manifestations. Autoimmune thyroid diseases are common in HCV infected patients and the standard interferon-based treatment is associated with an increase of the immune-mediated thyroid damage. Recent evidence in the literature analyzed critical points of the mechanisms of thyroid damage, focusing on the balance between the two sides of the interaction: The environment (virus infection with potential cross-reaction) and the host (susceptibility genes with consistent immune response). The spectrum of antiviral treatment for chronic HCV infection is rapidly expanding for the development of dual o triple therapy. The availability of interferon-free combined treatment with direct antiviral agents for HCV is very promising, in order to ameliorate the patient compliance and to reduce the development of thyroid autoimmunity.

Tighter glycemic control is associated with ADL physical dependency losses in older patients using sulfonylureas or mitiglinides: Results from the DIMORA study. Metabolism 2015; 64:1500-6.

Abstract
BACKGROUND There is growing evidence that tight glycemic control may be more harmful than beneficial in older persons with Type 2 diabetes (T2DM). It remains controversial if tight glycemic control (lower glycated hemoglobin A1c (A1c)) is associated with functional impairments in older frail patients with T2DM. We explored associations between A1c and losses in Activities of Daily Living (ADLs) in diabetic nursing home (NH) patients and tested for differences according to anti-diabetic treatment: diet, anti-diabetic oral drug (AOD), insulin, combined insulin+AOD. METHODS We conducted a cross-sectional study on 1845 older NH patients with T2DM from 150 sites across Italy. Complete evaluations on ADLs, glycemic control, anti-diabetic treatments, comorbidities, and clinical data were recorded. ANOVA was applied to compare clinical characteristics across A1c tertiles. Multivariate regression models evaluated associations between A1c and ADL losses. RESULTS Patients had a mean age [SD]=82 [8] years; BMI=25.5 kg/m(2) [4.7]; Fasting Plasma Glucose (FPG)=7.4 [3.0] mmol/l; Post-prandial glucose (PPG)=10.3 [3.6] mmol/l; A1c=7.0% (54 mmol/mol), ADL losses=3.7 [1.8]. Compared to higher A1c tertiles, patients in the lower tertile had greater ADL losses, were more likely to use AODs, while less likely to use insulin or insulin+AOD. After adjusting for multiple confounders, impairments in ADLs were associated with tighter A1c levels (B=-0.014; p=0.002). Regression models according to anti-diabetic treatment showed that tighter A1c levels continued as independent determinants of ADL losses in patients using AODs (B=-0.023; p=0.001), particularly in those using sulfonylureas (B=-0.043; p<0.001) or mitiglinides (B=-0.044; p=0.050). CONCLUSIONS Tighter glycemic control was associated with ADL physical dependency losses, especially in those using sulfonylureas and mitiglinides.

Abstract
The association between diabetes and neurodegenerative diseases is increasing with aging. Several common mechanisms are involved in both these diseases. The endothelial cells of the blood brain barrier, neurons and glia express typical and different receptors of the glucose metabolism (glucose transporters, insulin receptors and glucagon-like peptide-1 receptors). The impairment in insulin signaling leads to an impairment of neuronal function and increases neurodegeneration, and, conversely, neurodegeneration causes a reduction of insulin signaling on neurons. Increased detailed knowledge of common physiological processes opens up the opportunities for developing new treatments that may prevent or reduce the onset of neurodegenerative diseases. The aim of the review is to discuss the potential neuroprotective effects of the antidiabetic drugs. The article presents some promising patents on the treatment of insulin resistance in the neurodegeneration.

Abstract
Hepatic glycogenosis (HG) in type 1 diabetes is a underrecognized complication. Mauriac firstly described the syndrome characterized by hepatomegaly with altered liver enzymes, growth impairment, delay puberty and Cushingoid features, during childhood. HG in adulthood is characterized by the liver disorder (with circulating aminotransferase increase) in the presence of poor glycemic control (elevation of glycated hemoglobin, HbA1c levels). The advances in the comprehension of the metabolic pathways driving to the hepatic glycogen deposition point out the role of glucose transporters and insulin mediated activations of glucokinase and glycogen synthase, with inhibition of glucose-6-phosphatase. The differential diagnosis of HG consists in the exclusion of causes of liver damage (infectious, metabolic, obstructive and autoimmune disease). The imaging study (ultrasonography and/or radiological examinations) gives information about the liver alterations (hepatomegaly), but the diagnosis needs to be confirmed by the liver biopsy. The main treatment of HG is the amelioration of glycemic control that is usually accompanied by the reversal of the liver disorder. In selected cases, more aggressive treatment options (transplantation) have been successfully reported.

Abstract
This document is a Joint Position Statement by Gruppo Italiano di OrtoGeriatria (GIOG) supported by Società Italiana di Gerontologia e Geriatria (SIGG), and Associazione Italiana Psicogeriatria (AIP) on management of hip fracture older patients. Orthogeriatric care is at present the best model of care to improve results in older patients after hip fracture. The implementation of orthogeriatric model of care, based on the collaboration between orthopaedic surgeons and geriatricians, must take into account the local availability of resources and facilities and should be integrated into the local context. At the same time the programme must be based on the best available evidences and planned following accepted quality standards that ensure the efficacy of the intervention. The position paper focused on eight quality standards for the management of hip fracture older patients in orthogeriatric model of care. The GIOG promotes the development of a clinic database with the aim of obtaining a qualitative improvement in the management of hip fracture.

Abstract
UNLABELLED A successful therapy needs high level of adherence consisting in right drug intake in terms of persistence and compliance. Our study suggests adherence is higher if spot (less than 30 days) therapies are excluded; the analysis of spot therapy causes underlines the importance of the interpersonal aspects of medical practice. INTRODUCTION A successful therapy needs a high level of adherence consisting in right drug intake in terms of persistence and compliance. The aim of this study was to evaluate anti-osteoporotic therapies recorded in general practitioner databases in the area of Rome, which used the same computerized medical record management. The study focused on evaluating therapy adherence, any adherence changes excluding spot therapies (less than 30 days), and any cause of early therapy discontinuation in a subgroup of patients randomly selected. METHODS Thirty-one databases were evaluated, including a total of 6,390 anti-osteoporotic therapies: 5,853 were prescribed to women and 537 to men. The prescribed drugs were: vitamin D (13 %), calcium (8.7 %), vitamin D + calcium (40.1 %), raloxifene (3.3 %), alendronate (16.4 %), risedronate (7.7 %), clodronate (10.4 %), or other drugs (0.4 %). Spot therapies represented 53.7 % of the total prescriptions. The difference between adherence in the total group (24.64 %) and the group excluding spot therapies (43.38 %) is significant. The main factors influencing low adherence were side effects (27 %), misinformation given by the physician (17 %), insufficient motivation (9 %), difficult intake (9 %), and no perceived benefits (9 %). RESULTS Our study suggests adherence is high and similar to other chronic diseases if spot therapies are excluded. The analysis of spot therapy causes suggests that an important role is played by the physician and the interpersonal aspects of medical practice, especially at the first prescriptions. CONCLUSIONS The physician should collaborate with patients in choosing a personalized medical treatment. Reducing spot therapy could be the real goal in order to improve anti-osteoporotic therapy adherence.

Abstract
Glucocorticoid-induced osteoporosis (GIO) is the most frequent cause of secondary osteoporosis. GIO is linked to glucocorticoids (GC) daily assumption with maximum effect within first months of treatment and decreasing to basal levels as the therapy is discontinued. In Italy, primary prevention of GIO is suggested when GC therapy (prednisone >5 mg/day or equivalent) is taken for longer than 3 months. Lazio GISMO (Italian Group for Study and Diagnosis of Bone Metabolism Diseases) group organized the GC and Osteoporosis Epidemiology study (EGEO) to evaluate physician's approach in preventing GIO. The study involved 19 osteoporosis centers. Patients taking long-term GC therapy were recruited and information collected: medical history and anthropometric data, GC therapy, primary disease, physician's specialty, osteopororosis screening, and pharmacological intervention. The study included 1334 patients. Mean age was 63 ± 13 yr; 243 (18%) patients had a history of falls from standing position in the previous 12 months, 78 (35%) vertebral fractures, 91 (41%) fractures other than vertebral, 27 (12%) femoral fractures, and 27 (12%) multiple sites fractures. The molecules of GC more often prescribed were prednisone and 6-metil prednisolone. One thousand and forty patients (78%) were taking GC for more than 6 months. GC therapy was prescribed more frequently by rheumatologists (62%). Antiosteoporotic drugs for GIO prevention were prescribed in 431 patients (32%). Among the patients, only 27% (360) received calcium and vitamin D supplements, and 39% (319) treated by rheumatologists received anti-resorptive drugs. In conclusion, our data show that in Italy, as already described elsewhere, only a small subpopulation of GC-treated patients was supported by an anti-osteoporotic therapy, indicating the need to further stimulate awareness of both patients and specialists, prescribing GC therapy, to an appropriate and prompt GIO prevention.

Abstract
A sexual dysmorphism in the immune response has been described and females display an increased incidence of autoimmune diseases. Experimental data show that sex steroids influence immune cell development and have immunomodulatory effects. The distribution, the action (genomic and nongenomic), the sex and tissue-depending expression pattern of estrogen, progesterone and androgen receptors and their functional disruptions in corresponding receptor knockout animals will be discussed, pointing out the difference among sex steroid hormones. Recent advances indicate an immunomodulatory role of sex steroids in the pathogenesis of systemic lupus erythematosus, multiple sclerosis and rheumatoid arthritis. The outcomes of the clinical trials will help to find the best use of sex steroids in combination with current therapeutic drugs in autoimmune diseases. Sex steroid receptor modulating drugs will provide new therapeutic approaches in these pathologies.

Abstract
INTRODUCTION Bisphosphonates are the first-choice treatment for osteoporosis. They effectively increase bone mineral density, reduce markers of bone resorption, and lower the incidence of new fractures in patients with osteoporosis-related fracture. However, the efficacy observed in clinical trials may not be realized in a real-life setting, partly due to poor adherence to therapy, with a significant worsening of clinical outcomes. Several issues contribute to poor adherence to osteoporosis medication, including inconvenient dosing regimens and concerns about possible adverse events. Although strategies to improve adherence have been investigated, new approaches are required. AREAS COVERED We review available data and propose a new approach to improve adherence to osteoporosis therapy in clinical practice. We present the current evidence and personal experience from a group of Italian osteoporosis experts. EXPERT OPINION To improve adherence, we propose a multifaceted approach, which includes the Triad Model suggested by the World Health Organization, direct observed therapy and the use of drugs with longer administration intervals, e.g., zoledronic acid. The integration of these strategies may provide the basis for a marked increase in adherence to osteoporosis therapy, and improved clinical outcomes in a real-life scenario.

Abstract
OBJECTIVES Evidence in the literature suggests stress-related changes of hypothalamus-pituitary-adrenal (HPA) axis in mobbing. We investigated the association between HPA activity and psychological profiles in mobbing, using a multidisciplinary approach. DESIGN Forty-eight victims of mobbing were evaluated by a working group of the Departments of Occupational Medicine, Psychiatry and Internal Medicine. After an informed consent, a detailed occupational history, a psychiatric interview with Minnesota Multiphasic Personality Inventory 2 (MMPI-2) administration and a blood sample (8:00 AM) for the determination of basal adrenocorticotropin (ACTH), cortisol and dehydroepiandrosterone sulphate (DHEAS) plasma levels were collected. Twenty-six patients received an overnight dexamethasone (dex) test. RESULTS Mean ACTH, cortisol and DHEAS levels were within normal ranges. The dex-test response was normal, with a significant hormone suppression (ACTH p<0.001, cortisol p<0.001, DHEAS p<0.001). The correlations between basal hormones and the psychometric scales of MMPI-2 revealed that cortisol was significantly and negatively related to Psychasthenia (Pt, p=0.003) and Depression (D, p=0.006), while DHEAS showed a significant negative correlation to Hysteria (Hy, p=0.008). Basal ACTH levels were not significantly related to psychometric scales. CONCLUSION A significant inverse correlation between morning plasma cortisol levels and psychometric parameters in victims of mobbing with adjustment disorders was observed. A larger group of patients is necessary to identify and validate a cut-off cortisol level that may become an innovative biological parameter for the diagnosis and follow-up in victims of mobbing.

Arbuscular mycorrhizae increase the arsenic translocation factor in the As hyperaccumulating fern Pteris vittata L. CHEMOSPHERE 2006; 65:74-81.

Abstract
Phytoremediation techniques are receiving more attention as decontaminating strategies. Phytoextraction makes use of plants to transfer contaminants from soil to the aboveground biomass. This research is devoted to study the effects of arbuscular mycorrhizae (AM) on growth and As hyperaccumulation in the Chinese brake fern Pteris vittata. We grew for 45 days P. vittata sporophytes, infected or not infected with the AM fungi Glomus mosseae or Gigaspora margarita, in a hydroponic system on quartz sand. As-treated plants were weekly fed with 25 ppm As. The As treatment produced a dramatic increase of As concentration in pinnae and a much lower increase in roots of both mycorrhizal and control plants. Mycorrhization increased pinnae dry weight (DW) (G. margarita = G. mosseae) and leaf area (G. margarita > G. mosseae), strongly reduced root As concentration (G. mosseae > G. margarita), and increased the As translocation factor (G. mosseae > G. margarita). The concentration of phosphorus in pinnae and roots was enhanced by both fungi (G. margarita > G. mosseae). The quantitatively different effects of the two AM fungi on plant growth as well as on As and P distribution in the fern suggest that the As hyperaccumulation in P. vittata can be optimized by a careful choice of the symbiont.

Abstract
OBJECTIVES The interferon-alpha (IFN-alpha) therapy for HCV hepatitis may exacerbate or induce underlying thyroid disorders. Besides viral factors, the human leukocyte antigen (HLA) may be an independent risk factor. METHODS We evaluated fifteen patients with HCV chronic hepatitis during a period of 40 months. At the enrollment, all the patients were negative for thyroid disorders, excluding one patient with subclinical hypothyroidism. Eleven patients received IFN-alpha therapy. The HLA system was examined in every patient, evaluating antigens (n=40) of locus A, B and Cw and alleles (n=19) of locus DRB1* and DQB1*. The HLA system was also examined in healthy subjects (n=107) as a control group. RESULTS The HCV genotype distribution in patients was: 1b=20%, 2a=60%, 3a=20%. Four IFN-treated patients presented clinical thyroid disorders, including autoimmune hypothyroidism (n=2), transient thyrotoxicosis (n=1) and subacute thyroiditis (n=1). The HLA susceptibility to thyroid disorders (antigen/allele frequency) in the whole group of patients was not different in respect to controls and normal Italian population. The patients with HCV chronic hepatitis that developed thyroid diseases after IFN- treatment had a double and specific association with the HLA system (Mantel-Haenszel X(c)(2)=4.706, p<0.05). CONCLUSIONS This case report suggests that HLA system examination is an important and promising diagnostic aspect that may be considered in order to evaluate the appearance of thyroid disorders during the IFN-alpha treatment for HCV-related chronic hepatitis.

The hypothalamic-pituitary-thyroid axis in subjects with subclinical thyroid diseases: the impact of the negative feedback mechanism. NEURO ENDOCRINOLOGY LETTERS 2004; 25:292-6.

Abstract
OBJECTIVE To evaluate the hypothalamus-pituitary-thyroid (HPT) axis in patients with subclinical thyroid dysfunction recently reported to have either symptoms or organ involvements with potential morbidity, in order to better differentiate these patients with respect to controls. PATIENTS Sixtythree patients with subclinical hyperthyroidism (HyperT), 178 normal subjects (EuT) and 106 patients with subclinical hypothyroidism (HypoT) were enrolled; the groups presented normal thyroid hormone (FT4, FT3) levels and, respectively, reduced (HyperT), normal (EuT) and increased (HypoT) TSH levels. The negative feedback was simultaneously evaluated by multiple linear regression. RESULTS The mean TSH, FT4 and FT3 levels were significantly different in the three groups. The negative correlation between thyroid hormones (FT4 and FT3) and TSH secretion was significant (p<0.001 in HyperT; p<0.01 in EuT; p<0.000001 in HypoT group). FT4 mostly contributed to the negative correlation with TSH. The normal ranges of TSH values was accurately defined on the basis of the regression equation in the EuT group, due to the combining influence of both thyroid hormones (FT3 and FT4). No patient of the HyperT or HypoT group fell inside the range of estimated values of the normal group. CONCLUSIONS The HPT axis in patients with subclinical hyper- and hypo-thyroidism is significantly modified with respect to normal subjects. The status of the axis, as evaluated by the relationship between the three hormones (FT4, FT3, TSH) together considered, is characteristic of the normal or pathologic condition. A reliable method based on the regression analysis is proposed to correctly evaluate the status of the HPT axis.

Increased serum concentration of nerve growth factor in patients with microprolactinoma. Neuropeptides 2004; 38:21-4.

Abstract
Nerve growth factor (NGF) is known to play a role as a circulating neurokine, integrating signals from the neuro-immuno-endocrine system. The ability of NGF to activate the pituitary-adrenocortical axis, together with the increase of its serum concentration in pregnancy and lactation, supports the hypothesis that NGF is secreted by the pituitary gland and plays a role as modulator of endocrine functions. Evidence obtained both in vitro and in vivo in experimental animal models suggests that lactotroph cells secrete both prolactin (PRL) and NGF. Furthermore, in previous studies we demonstrate that cell lines derived from dopamine (DA)-sensitive human prolactinomas express high levels of NGF messenger RNA and protein. On these basis, we studied serum NGF concentrations in female patients with microprolactinoma (n = 4) and in control women (n = 5). PRL and NGF were measured at the diagnosis, during the thyrotropin releasing hormone (TRH) test and after the therapy with DA D2 receptor agonist cabergoline (0.25 mg, twice a week). Results obtained suggested that hyperprolactinemia (70.3+/-8.4 ng/ml) paralleled markedly higher NGF levels (58.4+/-18.7 pg/ml) compared to controls (PRL 8.7+/-3.2 ng/ml, NGF 8.4+/-1.3 pg/ml). Serum concentrations of NGF and PRL during the TRH test were closely associated (r = 0.943, p < 0.01). Cabergoline therapy normalized PRL (7.9+/-3.6 ng/ml) and induced a significant decrease of NGF levels (12.5+/-4.9 pg/ml). In conclusions, data reported here indicated that, in human microprolactinomas, NGF is released in the bloodstream paralleling PRL-secretion and it is modulated by a neurotransmitter-regulated mechanism, since the normalization of PRL elicited by the DA D2 receptor agonist cabergoline induced a significant decrease of serum NGF as well.

Abstract
OBJECTIVES Pilots are exposed to the "stress of flight" and the chronically activated stress response may play an important role in circulatory system disease progression. We studied the effect of an experimental mental stress on cardiovascular and neuroendocrine activity, in Air Force Academy cadets, before and after one month intensive course. DESIGN Nine cadets were submitted to a psychometric evaluation before Stroop test (ST), including Minnesota Multiphasic Personality Inventory, State and Trait Anxiety Inventory (STAI X1 and X2 form) and Reaction Scheme Test. After ST, subjects completed a STAI X1 form. Heart rate (HR), systolic and diastolic blood pressure (SBP and DBP) were monitored and serum prolactin (PRL), growth hormone (GH), adrenocorticotropin (ACTH) and cortisol levels were determined, during ST. The protocol was repeated at the end of the course. RESULTS No significant differences were evident in PRL, GH and ACTH levels. Cortisol concentrations were significantly higher before the course. ST did not modify hormone secretion. ST induced a significant and reproducible elevation of HR and SBP. Basal HR, SBP and DBP values were significantly elevated after the course. Two subjects presented a particular psychometric profile, a different cardiovascular response to ST and did not pass the course. CONCLUSIONS acute mental stress significantly activated cardiovascular response without modifying endocrine responses, in relation to the psychological profiles. A significant increase of cardiovascular parameters was present after the course, with enhanced dichotomy between the endocrine and sympathetic system, suggesting a careful evaluation and follow-up for circulatory system diseases in cadets.

Abstract
A role of nerve growth factor (NGF) in the neuro-endocrine-immune interactions has been recently suggested by the presence of NGF and its receptors in cells of the immune and endocrine systems. The improvement in the comprehension of the role played by NGF in humans is linked to the availability of a sensitive and reliable method to quantify NGF concentrations in body fluids and tissues. As a consequence of different methods used, normal levels of human serum NGF reported in the literature show wide differences. The present results indicate that ELISA appears very sensitive (detection limit 1.4pg/ml) and allows the discrimination of subtle variations of serum NGF concentrations. ELISA performed in serum obtained from men indicated that NGF concentration was 40.8+/-10.8pg/ml, whereas women showed significantly lower levels that were influenced by the menstrual cycle. In particular, the mean value of this neurotrophin during the follicular phase was 8.2+/-1.4pg/ml; the luteal phase, in turn, showed levels up to 14.4+/-2.9pg/ml. The difference of serum NGF concentrations between the follicular and luteal phase in each woman was statistically significant. Differences in NGF concentrations between men and women (in both phases of the menstrual cycles) were also statistically significant. In conclusion, a possible role of sex steroids as modulators of NGF secretion in humans is strongly supported by the present paper. However, mechanisms underlying this phenomenon are still unknown. The evidence indicating physiological sex hormone-related variations in NGF levels would be of interest in view of the possible use of circulating NGF modifications as a laboratory biomarker in different diseases.

Abstract
A mild prevalence of multiple sclerosis (MS) is present in females (2:1). To elucidate the pathogenetic role of sex steroids on the disease, we studied 76 women affected by MS, compared to 50 healthy women (mean age +/- SD, 34.9 +/- 0.9 vs. 33.4 +/- 1.7 years). The menarche was at mean age of 12.3 +/- 0.2 vs. 12.4 +/- 0.2. Interval between menses was 28.0 +/- 0.3 vs 27.8 +/- 0.3 days, with duration of menstrual flow of 5.0 +/- 0.2 vs. 5.0 +/- 0.2 days. Oligo- or amenorrhea was present in 20% of patients and in 16% of controls. Oral contraceptives were assumed by 21% of patients and 34% of controls (n.s.). Premenstrual symptoms were found in 43% of patients and in 46% of controls (n.s.). The incidence of hyperandrogenism (greasy skin, acne and hirsutism), evaluated by a specific questionnaire, was higher and statistically significant in MS patients than in controls (28% vs. 10%, p<0.05). Further studies, including a complete clinical and laboratory evaluation of gonadal function, are necessary in order to clarify whether hyperandrogenism may influence MS disease activity.

Abstract
OBJECTIVES The authors described a case of Hashimoto's disease during interferon-alpha (IFN-alpha) treatment for chronic viral C hepatitis in a patient with the specific genetic susceptibility associated with the thyroid disease. RESULTS A 60-year-old woman with chronic active viral C hepatitis (HCV genotype = 3a) started IFN-alpha therapy in November '96. Before treatment thyroid function tests were normal and anti-thyroid (anti-thyroglobulin and anti-thyroid peroxidase) Abs were negative. During IFN therapy, serum aminotransferases fell within the normal range and viremia (serum HCV-RNA) became negative after one year. After 20 months, the patient presented clinical features of primary hypothyroidism. Anti-thyroid Abs were found positive. Hormonal, ultrasonographic, radioiodine scanning and fine needle aspiration findings were consistent with the diagnosis of Hashimoto's thyroiditis. The tissutal typing of the patient showed the presence of Human Leukocyte Antigen (HLA) DRB1*11 gene (corresponding to DR5 antigen). IFN-alpha therapy was suspended and a treatment with l-T4 started. Chronic viral infection relapsed after the suspension of the IFN-alpha therapy. CONCLUSIONS This case report showed that the clinical appearance of Hashimoto's disease after IFN-alpha therapy for chronic C hepatitis in our patient was associated with a specific genetic predisposition (DR5) for this pathology. Further studies are necessary to evaluate whether the study of HLA antigens may be a very useful tool to detect the patients with a predisposition to develop autoimmune thyroiditis, in order to make a early diagnosis of thyroid disorders during the IFN-alpha treatment.

Abstract
It is well known that thyrotoxicosis may elicit acute myocardial ischemia even in patients with angiographically normal coronary vessels. The involved mechanisms are not clearly defined although some hypothesis have been suggested. We report a case of a 54-year-old woman affected by Graves' disease with thyrotoxicosis which was referred to our Institute because of unstable angina. During hospitalization a two dimensional echocardiogram, performed during chest discomfort, showed left ventricular apical akinesis and impaired global systolic function. A subsequent coronary angiography revealed normal epicardial vessels. She was successfully treated with high-dose methimazole and propranolol and a repeat echocardiogram evaluation showed normalization of left ventricular systolic function. Six months later, because of the appearance of paroxysmal atrial fibrillation, the patient underwent total thyroidectomy and a substitutive therapy with L-T4 (100 micrograms/die) was started. The authors review the possible mechanisms involved in the pathogenesis of myocardial ischemia during thyrotoxicosis.

Abstract
We investigated MRI activity in MS during the menstrual cycle in relation to physiologic sex hormone fluctuations. Eight women with relapsing-remitting MS were submitted to serial brain gadolinium-enhanced MRI examinations over a 3-month period in two alternate follicular and luteal phases of the menstrual cycle. The ratio of progesterone/17-beta-estradiol during the luteal phase was significantly associated with both number (r = 0.6, p = 0.03) and volume (r = 0.7, p = 0.009) of enhancing lesions, providing support for a role of these hormones as immunomodulatory factors in MS.

Abstract
OBJECTIVE To evaluate the outcome after total and subtotal thyroidectomy for the treatment of single and multinodular goitres in two comparable groups of patients. DESIGN Prospective randomised study. SETTING University hospital, Italy. SUBJECTS 141 Patients operated on for benign goitre from 1975-85. INTERVENTIONS 69 Patients were randomised to have total thyroidectomy and 72 subtotal thyroidectomy by standard techniques. MAIN OUTCOME MEASURES Temporary or permanent palsy of the recurrent laryngeal nerve, temporary or permanent hypoparathyroidism, recurrence of the goitre, and the incidence of iatrogenic injuries after completion thyroidectomy. RESULTS Patients were followed up for a median of 14.5 years (range 10-21). After total thyroidectomy 2 patients (3%) developed temporary palsy of the recurrent laryngeal nerve but there were no permanent lesions; and 24 (35%) developed temporary and 2 (3%) permanent hypoparathyroidism. After subtotal thyroidectomy 2 (3%) developed temporary and 1 (1%) permanent palsy of the recurrent laryngeal nerve; and 13 (18%) developed temporary and 1 (1%) permanent hypoparathyroidism. In addition, there were 10 recurrent goitres (14%). After completion thyroidectomy (n = 9) there were 2 cases of temporary and 1 of permanent palsy of the recurrent laryngeal nerve, and 2 cases of temporary and 2 of permanent hypoparathyroidism. CONCLUSION Total thyroidectomy is the procedure of choice for the treatment of benign nodular goitre.

A 34-year-old woman with chronic hepatitis C received interferon-alpha (IFN-alpha) therapy. Her thyroid function was normal and thyroid autoantibodies were negative before treatment. Four months after the beginning of the therapy she presented a clinical course of thyroiditis with a transient thyrotoxicosis. The diagnosis of subacute thyroiditis was confirmed by laboratory, ultrasonography, radioiodine scanning and fine needle aspiration findings. Thyroid autoantibodies were persisting negative. She suspended IFN-alpha therapy and she started non steroidal anti-inflammatory agents and beta-blockers. Latent hypothyroidism subsequently developed, but L-thyroxine therapy resulted in a rapid normalization of thyroid function tests.

Abstract
Recent studies pointed out the development of autoimmune thyroid diseases during interferon (IFN) therapy, mainly in patients with positive thyroid autoantibodies (MsAb and TgAb) before treatment. The effects of recombinant human IFN alpha (rhIFNalpha) on thyroid function and thyroid autoantibodies were studied in 12 patients with chronic active hepatitis associated with virus B or C, selected on the basis of negative results for MsAb and TgAb. No significant variation in T3, T4 and TSH levels was observed either after the first administration of rhIFN alpha (3 million IU i.m.) or after three months of therapy (3 million IU i.m. 3 times a week). TSH response to TRH was in the normal range either before or after the therapy. The absence of MsAb and TgAb was confirmed in all the patients at the end of the treatment. These results indicate that no patient developed thyroid disorder during IFN therapy. Nevertheless, since positive MsAb and TgAb have been considered as a risk factor for thyroid diseases, in patients selected for IFN therapy they should be carefully assessed for autoantibodies before undergoing IFN treatment.

Abstract
OBJECTIVE To evaluate the effects on hormonal and metabolic variables and bone density of a transdermal system delivering estrogen and progestagen. DESIGN Twenty-one patients were included in the study and randomly assigned to the following treatments: group A was treated with transdermal 17 beta-estradiol, 50 micrograms/day (Estraderm TTS 50), from the first to the fourteenth day of the cycle and with a transdermal combination of 17 beta-estradiol (50 micrograms/day) and norethisterone acetate (NETA) 250 micrograms/day during the following 14 days; group B was treated with Estraderm TTS 50 from the first to the twenty-eighth day, adding oral medroxyprogesterone acetate (MPA), 10 mg/day, during the final 14 days. DHEAS, testosterone, SHBG, prolactin, gonadotropins, and estrogens were measured in basal conditions and after 6 months' therapy. In the same schedule, lipid patterns (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides), phosphocalcium variables (osteocalcin, calcitonin, parathormone), and bone mineral density were also studied. RESULTS Both treatments were efficient in reducing menopausal symptoms. An increase of DHEAS (P < .05) and a decrease of FSH and LH (P < .02, < .01, respectively) were observed in group B. No significant modifications in lipid and lipoprotein metabolism were shown in either group after 6 months. The calcium-regulating hormone osteocalcin (BCG) decreased significantly (P < .05) only in group A; calcitonin, parathormone, and bone density were unchanged after treatment. CONCLUSION Transdermal administration of estrogen plus progestagen reduces menopausal symptoms, but does not induce changes in metabolic variables and hormonal levels (androgens and prolactin).

Abstract
A 38 year old woman and her first cousin, a 41 year old man, presented both with hypertension, hypokalemia, hyperaldosteronism, and low plasma renin activity in our Hospital. In both patients, plasma and urine aldosterone were constantly above the normal range, even on a high NaCl diet (250 mEq/day), while the plasma aldosterone response to postural changes was normal. In the female patient abdominal ultrasonic scan, CT scan, MRI, and adrenal gland phlebography were normal, but blood from the left adrenal vein contained 1002 pg/ml of aldosterone, versus 91 pg/ml in the contralateral one. Interestingly, the secretion of cortisol was also lateralized (plasma cortisol levels being of 28.8 mcg% in the left, 2.3 mcg% in the right adrenal gland), although neither clinical nor laboratory signs of hypercortisolism were present. Spironolactone treatment (100 mg/daily) completely reversed the syndrome of mineralocorticoid excess. After 2 years, patient has normal blood pressure and serum K+ levels.
