    [Show abstract] [Hide abstract] ABSTRACT: A case of Cushing’s syndrome in a 24-yr-old homosexual with an AIDS-related complex is reported. In this patient certain symptoms common to both diseases, i.e. weakness, myalgia and muscle atrophy were accentuated, whereas other symptoms pathognomic of the human immunodeficiency virus (HIV) infection, i.e. lymphoadenopathies and weight loss, were less pronounced by the high levels of circulating adrenal steroids. Ketoconazole was administered po in order to block adrenal steroidogenesis, the drug caused a remarkable fall of cortisol serum concentrations, but was unable to modify significantly the immunological pattern of the patient. Our data suggest that changes of serum adrenal steroid levels have little effect on the immune network of patients with AIDS.

  • [Show abstract] [Hide abstract] ABSTRACT: Purpose: The aim of this study is to investigate in a population of adolescents living in Regione Campania, undergoing sun exposure at least 9 months per year the prevalence of severe deficiency (<20 ng/ml) or insufficiency (21-29 ng/ml) of 25-Hydroxyvitamin D (25(OH)D) levels and its relationship with individual body weight, use of smoking, and exercise performance. Methods: From October 2012 to October 2013, 373 healthy subjects (153 girls, 223 boys 11-20 years) without chronic diseases were consecutively enrolled in a campaign to prevent metabolic, cardiovascular, and oncological diseases. 25(OH)D assay, BMI, and lifestyle habitudes (smoking and exercise indoor or outdoor) were assessed. Results: In this population, median 25(OH) level was 25.0 ng/ml (95 %CI 23.8-25.2) without any difference between girls (25.0 (95 %CI 23.1-25.7)) and boys (24.3 (95 %CI 23.8-25.2)). Severe deficiency was found in 6 girls (0.02 %), while insufficiency was found in 296 patients (110 girls, 79.3 %). Normal levels were found in 71 patients (37 girls, 19 %). Vitamin D levels were significantly correlated with BMI (r = -0.429, p < 0.0001), smoking (r = -0.241; p < 0.0001), and exercise performance (r = 0.791; p < 0.0001). At the multistep regression analysis, Vitamin D levels were best predicted by exercise performance (t = 19.6, p < 0.0001), less smoking addiction (t = -4.97, p < 0.001), and lower BMI (t = -4.69, p < 0.0001). Conclusions: The current study demonstrates that Vitamin D levels are commonly unsatisfactory in adolescents. Lower levels were found in overweight or obese adolescent, smokers and with low or absence of physical activity outdoors.

  • [Show abstract] [Hide abstract] ABSTRACT: The cellular abundance of the phosphoprotein enriched in diabetes (PED/PEA-15), a 15 kDa protein related to insulin resistance (IR), is increased in women with polycystic ovary syndrome (PCOS). To investigate whether metformin (MET) has additive effects on PED/PEA-15 protein levels. This is an open label, prospective clinical study over 6 months. Ten hyperandrogenic obese PCOS women [age: 24.6+/-1.6 yr; body mass index (BMI): 30.7+/-1.2 kg/m(2)] were treated with MET (1250 mg/day). Ten age- and BMI-matched normo-androgenic women were used as controls. Outcome measures are: PED/PEA-15 protein levels, fasting plasma glucose and insulin (FPI), reciprocal index of homeostasis model assessment of insulin resistance (1/HOMA-IR); quantitative insulin sensitivity check index (QUICKI); wholebody insulin sensitivity index (ISI); SHBG; total testosterone; free androgen index (FAI). At baseline FPI and PED/PEA- 15 protein levels were higher, while 1/HOMA-IR, QUICKI, and ISI were lower (p<0.001) in MET group than in controls. After treatment, independently of body weight and hyperandrogenism, FPI, and PED/PEA-15 protein levels decreased (p=0.001 and 0.004, respectively), while, 1/HOMA-IR, QUICKI, and ISI increased (p<0.001). PED/PEA-15 protein levels correlated significantly with ISI either before (r=0.636; p=0.048), and after treatment (r=0.758; p=0.011). PED/PEA-15 protein levels reduced after a short course of treatment with MET in a group hyperandrogenic obese PCOS women. This effect was independent of body weight and hyperandrogenism, and correlated with ISI, thus adding a further benefit to obese PCOS women.

    [Show abstract] [Hide abstract] ABSTRACT: The aim of the current study was to evaluate the effectiveness of a long-term treatment with sodium valproate in 19 patients with Cushing's disease. Before therapy beginning, the patients were subjected to acute test with 600 mg sodium valproate. Then, they were subjected to a 3-month therapy with sodium valproate at the dose of 600 mg/day before surgery (presurgical study). The 7 patients not surgically cured were subjected again to a 3-month therapy with sodium valproate at the dose of 600 mg/day after surgery (postsurgical study). Circulating ACTH and cortisol and urinary free cortisol levels were evaluated before and monthly after the beginning of the therapy. A decrease of plasma ACTH and serum cortisol levels greater than 50% of baseline was considered as positive response to acute test whereas the normalization of plasma ACTH, serum cortisol and urinary free cortisol levels and the clinical remission were considered as positive response to the long-term treatment. At acute test, 8 patients were considered responders and 11 patients non-responders. In no patient plasma ACTH, serum cortisol and urinary free cortisol were normalized during the long-term treatment. Urinary free cortisol levels significantly decreased (483.2 +/- 33.8 vs 699.4 +/- 67.0 micrograms/24 h), whereas plasma ACTH (302.8 +/- 17.7 vs 183.3 +/- 25.0 ng/l) and serum cortisol (466.5 +/- 23.2 vs 356.7 +/- 19.6 micrograms/l) significantly increased during sodium valproate administration in the 19 patients enrolled in the presurgical study. Plasma ACTH (247.7 +/- 22.3 vs 168.6 +/- 15.0 ng/l), serum cortisol (387.4 +/- 35.8 vs 282.0 +/- 16.0 micrograms/l) and urinary free cortisol (370.9 +/- 70.6 vs 261.3 +/- 37.8 micrograms/24 h) levels significantly increased in the 7 patients enrolled in the postsurgical study. No patient had clinical remission of Cushing's disease. In conclusion, the current study showed that long-term therapy with sodium valproate is not useful in the therapeutic management of Cushing's disease neither as alternative nor as adjunctive therapy to surgery.

    [Show abstract] [Hide abstract] ABSTRACT: Pregnancy is becoming a relatively common event in patients with pituitary tumors (PT), due to the increasing availability of medical treatments, which control pituitary diseases associated with the development of PT. However, the presence of PT and its treatment may be a disturbing factor for pregnancy, and pregnancy significantly influences the course and the management of PT. This review summarizes the knowledge about the management of PT during pregnancy and the occurrence of pregnancy in patients with pre-existent PT, focusing on secreting PT characterized by hormonal excess and on clinically non-functioning PT often associated to hormone deficiency, which configure the hypopituitaric syndrome.

    [Show abstract] [Hide abstract] ABSTRACT: Objective Acromegalic patients have increased mortality. The objective of the study was to compare the effect of different therapies for acromegaly on mortality.Design&Methods Mortality of 438 consecutive acromegalic patients was compared to that of the general population by standardized mortality ratio(SMR);the effect of different therapies on survival was evaluated by Cox regression analysis.ResultsTwenty patients(4·5%) died between 1999 and 2009.Age and sex-adjusted SMR was 0·70(95% C.I., 0·43-1·08).Cox regression analysis revealed that, in the whole population, both general risks factors(age and the physical status), and specific factors for acromegaly(macroadenoma, hypopituitarism and uncontrolled disease) were associate with death. The most compromised patients at diagnosis had higher mortality(p=0·001), which occurred also in patients with controlled acromegaly.Death occurred in 2·4%(adenomectomy), 2·6%(adenomectomy followed by somatostatin analogues, SSA) and 11·4%(SSA as primary therapy) patients.The risk of death was higher in patients receiving SSA as primary therapy(Hazard Ratio, HR 5·518, 95% C.I., 1·058-28·767, p=0·043) than in all patients submitted to adenomectomy; however, a higher risk of death occurred only in diabetic patients treated with SSA alone(HR, 21·936, 95% CI, 1·557-309·04, p=0·022).Radiotherapy was associated with increased mortality, which occurred in patients with the more locally advanced disease.Conclusions Therapies of acromegaly and comorbidities have lowered mortality to the level of the general population;SSA alone or following pituitary adenomectomy was comparable to curative neurosurgery on survival in non-diabetic patients; on the contrary, SSA as primary therapy, may be less effective than adenomectomy in reducing mortality in diabetic patients.

    [Show abstract] [Hide abstract] ABSTRACT: The clinical conditions associated with GH excess and GH deficiency are known to be associated with an increased risk for cardiovascular morbidity and mortality, suggesting that either an excess or a deficiency in GH and/or IGF-I is deleterious for cardiovascular system. In patients with acromegaly chronic GH and IGF-I excess commonly causes a specific cardiomyopathy characterized by a concentric cardiac hypertrophy associated with diastolic dysfunction, and, in later stages, with systolic dysfunction ending in heart failure if GH/IGF-I excess is not controlled. Abnormalities of cardiac rhythm and anomalies of cardiac valves can also occur. Moreover, the increased prevalence of cardiovascular risk factors, such as hypertension, diabetes mellitus and insulin resistance, as well as dyslipidemia, confer an increased risk for vascular atherosclerosis. Successful control of the disease is accompanied by a decrease of the cardiac mass and improvement of cardiac function and an improvement in cardiovascular risk factors. In patients with hypopituitarism, GH deficiency has been considered the underlying factor of the increased mortality when appropriate standard replacement of the pituitary hormones deficiencies is given. Either childhoodonset or adulthood-onset GH deficiency are characterized by a cluster of abnormalities associated with an increased cardiovascular risk, including altered body composition, unfavourable lipid profile, insulin resistance, endothelial dysfunction and vascular atherosclerosis, a decrease in cardiac mass together with an impairment of systolic function mainly after exercise. Treatment with recombinant GH in patients with GH deficiency is followed by an improvement of the cardiovascular risk factors and an increase in cardiac mass together with an improvement in cardiac performance. In conclusion, acromegaly and GHD are associated with an increased risk for cardiovascular morbidity and mortality, but the control of GH/IGF-I secretion reverses cardiovascular abnormalities and restores the normal life expectancy.

  • [Show abstract] [Hide abstract] ABSTRACT: Purpose:Percutaneous radiofrequency thermal ablation (RTA) was reported as an effective tool for the management of thyroid nodules (TNs). The aim of this study was to investigate the effects of RTA and to establish whether they were treatment-related by comparison with a matched, untreated control group.Patients and Methods:The study population included 40 patients with compressive TNs: 22 had nontoxic TNs, and 18 had toxic TNs and were treated with methimazole. In all patients, a fine-needle aspiration cytology was performed to exclude a thyroid malignancy.Study Design:Twenty patients were treated with RTA (group A), and 20 others did not receive any treatment (group B). At baseline, age, gender, and TN features did not differ significantly between groups. All patients were clinically, biochemically, and morphologically evaluated at baseline and after 1, 3, 6, and 12 months.Results:TN volume significantly decreased in group A (1.8 ± 0.3 ml at 12 months vs. 13.3 ± 1.8 ml at baseline; P < 0.0001) and remained stable in group B [11.7 ± 1.5 ml at 12 months vs. 11.2 ± 1.5 ml at baseline; P = not significant (NS)]. At 3-, 6-, and 12-month evaluations, TN volume was significantly lower in group A than in group B (P < 0.005). At the end of the follow-up, pressure symptoms were improved in all patients in group A but persisted unchanged in group B. In group A, hyperthyroidism completely recovered in 40% and improved in 40% of patients with toxic TNs, whereas it persisted in all patients with toxic TNs in group B. RTA was safe and well tolerated in all patients.Conclusions:RTA induced a marked TN volume shrinkage resulting in parallel improvement of pressure symptoms. In most patients with toxic TNs, hyperthyroidism significantly improved as well. RTA may represent a valid therapeutic approach in patients with TNs not receiving conventional treatments.

    [Show abstract] [Hide abstract] ABSTRACT: To describe demographic and hormonal characteristics, comorbidities (diabetes mellitus and hypertension), therapeutic procedures and their effectiveness, as well as predictors of morbidity and mortality in a nationwide survey of Italian acromegalic patients. Retrospective multicenter epidemiological study endorsed by the Italian Society of Endocrinology and performed in 24 tertiary referral Italian centers. The mean follow-up time was 120 months. A total of 1512 patients, 41% male, mean age: 45±13 years, mean GH: 31±37 μg/l, IGF1: 744±318 ng/ml, were included. Diabetes mellitus was reported in 16% of cases and hypertension in 33%. Older age and higher IGF1 levels at diagnosis were significant predictors of diabetes and hypertension. At the last follow-up, 65% of patients had a controlled disease, of whom 55% were off medical therapy. Observed deaths were 61, with a standardized mortality ratio of 1.13 95% (confidence interval (CI): 0.87-1.46). Mortality was significantly higher in the patients with persistently active disease (1.93; 95% CI: 1.34-2.70). Main causes of death were vascular diseases and malignancies with similar prevalence. A multivariate analysis showed that older age, higher GH at the last follow-up, higher IGF1 levels at diagnosis, malignancy, and radiotherapy were independent predictors of mortality. Pretreatment IGF1 levels are important predictors of morbidity and mortality in acromegaly. The full hormonal control of the disease, nowadays reached in the majority of patients with modern management, reduces greatly the disease-related mortality.

    [Show abstract] [Hide abstract] ABSTRACT: Context: Usefulness of circulating Chromogranin A (CgA) for the diagnosis of neuroendocrine tumors (NEN) is controversial. The aim of the present study was to assess the actual role of this marker as diagnostic tool. Methods: Serum blood samples were obtained from 42 subjects affected with NEN, 120 subjects affected with non-endocrine neoplasias (non-NEN) and 100 non-neoplastic subjects affected with benign nodular goitre (NNG). Determination of CgA was performed by means of immunoradiometric assay. Results: The CgA levels among NEN-patients were not significantly different from NNG and non-NEN subjects. The Receiver operating characteristic (ROC) curves analysis failed to identify a feasible cut-off value for the differential diagnosis between NEN and the other conditions. Conclusion: Serum CgA is not helpful for the first-line diagnosis of NEN.

    [Show abstract] [Hide abstract] ABSTRACT: Abstract: In recent years, a significant increase in the incidence of male infertility has been observed and described in the international literature, raising questions about its causes. Several authors have suggested that exposure to environmental pollution may contribute to a perceived decline in semen quality worldwide. Although several studies have been conducted about the effects on male fertility caused by exposure to heavy metals in the workplace, research on the effects caused by continued exposure to low doses of heavy metals pollution in urban areas is still scarce. The aim of this study is to identify the relationships between high concentrations of heavy metals and male infertility in the metropolitan area of Naples. We considered only those elements (Al, As, Cd, Cr, Cu, Hg, Mn, Mo, Pb, Sb, Tl, Zn) that previous studies have indicated as possible candidates to have some influence on human semen quality. We measured semen quality among 600 subjects selected from a sample of 1237 men regularly examined at the andrology laboratory of the University of Naples "Federico II" for problems related to male fertility. Using statistical methods the semen data (semen volume, sperm concentration, sperm total count, sperm motility, pH) were compared with the geochemical distribution of heavy metals in soils of the Napoli metropolitan area. Results show a strong correlation between anomalous Pb and Sb concentrations and fertility disorder. A weaker correlation was also observed with Hg and Zn while the anomalous concentration values of the other elements (Al, As, Cd, Cr, Cu, Mn, Mo and Tl) appears to have no correlation with male infertility.
