RESUMO

PURPOSE: Cushing's disease (CD) is associated with significant clinical burden, increased mortality risk, and impaired health-related quality of life (HRQoL). This analysis explored the effect of long-acting pasireotide on clinical signs of hypercortisolism and HRQoL in a large subset of patients with CD. METHODS: In this phase III study (clinicaltrials.gov: NCT01374906), 150 adults with CD and a mean urinary free cortisol (mUFC) level between 1.5 and 5.0 times the upper limit of normal (ULN) started long-acting pasireotide 10 or 30 mg every 28 days with dose increases/decreases permitted based on mUFC levels/tolerability (minimum/maximum dose: 5/40 mg). Changes in clinical signs of hypercortisolism and HRQoL were assessed over 12 months of treatment and were stratified by degree of mUFC control for each patient. RESULTS: Patients with controlled mUFC at month 12 (n = 45) had the greatest improvements from baseline in mean systolic (- 8.4 mmHg [95% CI - 13.9, - 2.9]) and diastolic blood pressure (- 6.0 mmHg [- 10.0, - 2.0]). Mean BMI, weight, and waist circumference improved irrespective of mUFC control. Significant improvements in CushingQoL total score of 5.9-8.3 points were found at month 12 compared with baseline, irrespective of mUFC control; changes were driven by improvements in physical problem score, with smaller improvements in psychosocial score. CONCLUSIONS: Long-acting pasireotide provided significant improvements in clinical signs and HRQoL over 12 months of treatment, which, in some cases, occurred regardless of mUFC control. Long-acting pasireotide represents an effective treatment option and provides clinical benefit in patients with CD. CLINICAL TRIAL REGISTRATION NUMBER: NCT01374906.

RESUMO

Osteoporosis and avascular necrosis (AVN) are long-lasting and debilitating complications of hematopoietic stem cell transplantation (HSCT). We describe the magnitude of bone loss, AVN and impairment in osteogenic cell compartment following autologous (auto) and allogeneic (allo) HSCT, through the retrospective bone damage revaluation of 100 (50 auto- and 50 allo-HSCT) long-term survivors up to 15 years after transplant. Current treatment options for the management of these complications are also outlined. We found that auto- and allo-HSCT recipients show accelerated bone mineral loss and micro-architectural deterioration during the first years after transplant. Bone mass density (BMD) at the lumbar spine, but not at the femur neck, may improve in some patients after HSCT, suggesting more prolonged bone damage in cortical bone. Phalangeal BMD values remained low for even more years, suggesting persistent bone micro-architectural alterations after transplant. The incidence of AVN was higher in allo-HSCT recipients compared to auto-HSCT recipients. Steroid treatment length, but not its cumulative dose was associated with a higher incidence of bone loss. Allo-HSCT recipients affected by chronic graft versus host disease seem to be at greater risk of continuous bone loss and AVN development. Reduced BMD and higher incidence of AVN was partly related to a reduced regenerating capacity of the normal marrow osteogenic cell compartment. Our results suggest that all patients after auto-HSCT and allo-HSCT should be evaluated for their bone status and treated with anti-resorptive therapy as soon as abnormalities are detected.

RESUMO

OBJECTIVES: Baseline characteristics of the population enrolled in the ISSO study, designed to evaluate the incidence of vertebral and non-vertebral fractures in Italian patients with severe osteoporosis treated according to clinical practice over 24 months observation. METHODS: Prospective observational study in 783 post-menopausal women and men entering 18-month treatment with teriparatide in a community setting at 57 centres in Italy. Characterisation included demographics, fracture risk factors, bone mineral density, fracture status, Health-Related Quality of Life (HRQoL) measured by the European Quality of Life Questionnaire, EQ-5D, and back pain assessed by VAS. RESULTS: Most patients were elderly women (90.5%), mean age±SD was 72.9±8.8 years. Nearly all (91.3%) had experienced ≥ 1 vertebral fracture (mean±SD, 3.6±2.2 per patient), 37.5% had ≥ 1 non-vertebral fracture (mean±SD, 1.4±0.7 per patient). Nearly all patients were suffering from back pain (94.9%), which had significantly restricted their daily activities (51.7%) and had likely or very likely been caused by vertebral fractures (29.2% and 55.8%, respectively). Mean EuroQoL EQ-5D index value was 0.58±0.25 and VAS score 49.2±23.6. Non-vertebral fractures, back pain and multiple vertebral fractures were associated with lower HRQoL (EuroQoL-5D Index both p<0.001, EQ-5D VAS score p=0.025 and p<0.016, respectively). Many patients were physically inactive (81.1%). One third (34.7%) of population had co-morbidities and 60.5% were on chronic concomitant treatments. Few subjects reported a maternal history of osteoporosis (15.5%), regular consumption of alcohol (13.3%) or were current smokers (11.5%). Nearly two-thirds (71.5%) had already been treated for osteoporosis, mainly with bisphosphonates. Calcium and vitamin D supplements were taken by 13% and 15.5% of the total population, respectively. CONCLUSIONS: At enrollment, the population of ISSO study mostly consisted in aging women, who had osteoporosis with high fracture risk, poor HRQoL and suffered from significant back pain. Most of them had already been treated by bisphosphonates but without calcium and vitamin D supplements. Back pain, as well as non-vertebral and multiple vertebral fractures, were associated with lower HRQoL.

RESUMO

BACKGROUND: GH therapy response varies substantially among patients. Several models were developed to predict the efficacy of GH therapy in children. AIM: To evaluate the accuracy of a growth prediction model using data from an Italian pediatric GH deficiency (GHD) cohort (GeNeSIS, Growth Prediction Sub-study). METHODS: Open-label, multicenter study in 22 Italian pre-pubertal GH treatment- naïve patients with GHD (8 female, 14 male, 0.5 to 12.2 yr), 18 isolated GHD, 4 multiple pituitary hormone deficiency given recombinat human GH therapy (0.025-0.035 mg/kg/day) for 12 months. Growth prediction was performed, after 3 months of treatment, using baseline data [bone age (BA) and IGF-I], a urinary marker of bone turnover [deoxypyridinoline crosslinks (DPD)] at 4 weeks, and height velocity (HV) at 3 months. Results were expressed as 1st-yr HV using the following equation: 1-yr HV (cm) = 3.543 - (2.337 × BA) - (0.010 × IGF-I) + (0.100 × DPD) + (0.299 × 3-month HV). Predictions were compared to the 1st-yr HV and accuracy was calculated as percentage of the difference between mean calculated HV and the real 1st-yr HV. RESULTS: For females predicted HV was 12.98 ± 4.82 cm/yr and actually was 13.05 ± 3.91 cm/yr after the 1st year; for males predicted HV was 13.95 ± 5.39 cm/yr and actually was 12.93 ± 5.02 cm/yr. CONCLUSIONS: In this paediatric Italian cohort with GHD, a growth prediction model seems to be a valid tool to assess 1st-yr response to GH treatment in Italian children.

RESUMO

INTRODUCTION: Chronic mild endogenous glucocorticoid excess has been shown to cause bone loss and to increase fracture risk in both post-menopausal and premenopausal women. Currently, it is unclear if patients with subclinical Cushing's syndrome (SCS) with osteoporosis or osteopenia may benefit from antiresorptive treatment and the type of therapy to be given. OBJECTIVE: This pilot randomized study was aimed at evaluating the effects of 12-month im administration of clodronate (100 mg every week) on vertebral and femoral bone mineral density (BMD), bone turnover markers and on subjective pain in premenopausal women with SCS due to adrenal incidentalomas. METHODS: Forty-six women (age, 43.1+/-7.7 yr) with SCS due to adrenal incidentaloma and osteoporosis/osteopenia were randomized to receive clodronate plus supplement of Calcium (500 mg daily) and Vitamin D3 (800 mg daily) (group 1, no.=23) or supplements only (group 2, no.=23). Both groups were similar in terms of age, body mass index, cortisol levels, BMD values, and bone turnover markers. All of the women were re-evaluated after 12 months. RESULTS: After 12 months of treatment, in group 1, a significant increase in lumbar BMD occurred (p=0.04), while bone turnover markers decreased by about one third (p<0.05). In group 2, bone turnover markers did not change and BMD values slightly decreased (p=ns). The differences in bone turnover markers and in lumbar BMD between the two groups were significant (p<0.05, all). No new vertebral fracture occurred in group 1, while in group 2 the spine radiographies revealed 2 new fractures and a worsening of two pre-existent fractures. An improvement in subjective back pain, assessed by visual analogue scale pain score was observed in group 1 (from 4.3+/-2.7 to 2.9+/-2.0; p<0.05) but not in group 2 (from 4.4+/-3.1 to 4.2+/-3.4; p=ns). No significant changes occurred in cortisol secretion or clinical picture of the SCS during the study. CONCLUSIONS: Intramuscular administration of clodronate effectively increased lumbar BMD values, preserved bone mass at the femoral neck, stabilized vertebral fracture index, and decreased subjective back pain in pre-menopausal women with SCS. Since the untreated group continued to lose bone, antiresorptive treatment should be considered in patients with SCS, according to the prevision of surgical treatment, prevalent fractures, BMD values, age, concomitant morbidities, and desire for pregnancy.

RESUMO

The deficiency of 17 alpha-hydroxylase/17,20-lyase causes a rare autosomal recessive disorder presenting with congenital adrenal insufficiency (CAH) and sexual infantilism. Both 17 alpha-hydroxylase and 17,20-lyase reactions are catalyzed by a single polypeptide, cytochrome P450c17 (CYP17), which is encoded by the CYP17A1 gene. We describe the clinical, hormonal, and molecular findings of a 33-yr-old patient presenting with primary amenorrhea, late onset hypertension, and hypokalemic myopathy. The molecular analysis of CYP17A1 revealed a novel homozygous missense mutation resulting in the substitution of arginine to lysine at the amino acid position 21 (p.R21L).

RESUMO

Glucocorticoid-induced osteoporosis (GIO) is the most common form of secondary osteoporosis. GC influence bone metabolism via a modulation of different components of the GH/IGF-I system. GH has multiple anabolic effects on bone, either direct or mediated by IGF-I. GH-deficient subjects have significant reduction in bone mineralization, bone turnover markers, and increased fracture risk when compared with healthy age-matched controls. The increase of bone remodeling achieved by recombinant human GH (rhGH) therapy may be helpful in both males and females with decreased bone turnover and impaired osteoblastic function such as subjects with GC excess. rhGH treatment may improve lean body mass and skeletal muscle mass that may further reduce fracture risk in GIO patients. Nevertheless, the real efficacy of rhGH and IGF-I treatment in GIO and during aging is still controversial and further well-designed prospective controlled studies are necessary in order to clarify this issue, thus identifying who could potentially benefit from GH treatment.

RESUMO

GH deficiency (GHD) in adults is accompanied by reduced bone mass that may revert only after 2 yr of GH replacement. However, it is unclear whether the gender may modify bone responsiveness to GH replacement in adults. In this study we have evaluated whether bone mineral density (BMD) and turnover improve after GH replacement according to patients' gender. BMD at lumbar spine (LS) and femoral neck (FN), serum osteocalcin (OC), and urinary cross-linked N-telopeptides of type I collagen (Ntx) were assessed in 64 hypopituitaric patients (35 men, 30-50 yr) before and 2 yr after the beginning of GH replacement. Values of IGF-I and BMD at LS and at FN were expressed as Zscores. At study entry, IGF-I and BMD resulted similar among men and women with GHD. During GH replacement, IGF-I levels increased in both men and women without any difference in the percentage of IGF-I increase between the genders (p=0.47). In women receiving estrogen replacement, however, the percentage of IGF-I increase (p<0.05), and the Z IGF-I score (p<0.001) were significant lower than estrogen untreated women, although IGF-I levels were similar in the 2 groups (p=0.53). The GH dose adjusted for body weight required to restore normal age- and sex- matched IGF-I levels was lower in men than in women (p<0.001), and was higher in women receiving than in those not receiving estrogen replacement (p<0.05). In contrast, hypogonadal men treated with testosterone and eugonadal men received a similar GH dose (p=0.97). Also OC, Ntx levels, lumbar and femoral BMD improved (p<0.001) in all patients. Nevertheless, a greater increase in lumbar BMD increase was observed in men than in women (8.0+/-2.1 vs 2.6+/-0.4%; p<0.05). No significant difference was revealed in bone parameters in women treated or untreated with estrogen replacement and in men treated or not with testosterone replacement for concomitant hypogonadism. At the multiple correlation analysis, gender was a stronger predictor for the required GH dose than the age (p<0.001 and p=0.02, respectively). In conclusion, a 2-yr GH replacement normalizes IGF-I levels, increases bone mass and improves bone turnover both in men and in women with GHD without any difference between the 2 groups, provided that the dose of GH was modulated on the basis of IGF-I levels. Women receiving oral estrogens should receive a GH dose approximately doubled, as compared to men and women not receiving oral estrogens, to achieve similar effects on bone density and turnover. In particular, GH replacement dose, to be successful on bone mass and turnover, depends on gender in hypopituitary patients aged below 50 yr.

RESUMO

Adults with either GH deficiency (GHD) or GH excess have bone, metabolic, and somatic impairments. This review deals with available data on the relationship between GH status, bone mass, articular disorders, and body composition. GHD subjects have reduced bone mineralization and increased fracture rates. Acromegalic artropathy occurs in virtually all patients and in its late degenerative stages may resemble osteoarthritis. Abnormalities in GH/IGF-I were observed in patients with different forms of arthritis. When concerning body composition (BC), both severe and partial GHD are characterized by increased fat mass, especially truncal, and reduced lean mass. In acromegaly, an increase in body weight, lean mass, and extracellular water, and reduced fat mass were observed; these abnormalities did not always disappear after the normalization of GH/IGF-I levels. On the contrary, long-term GH replacement at physiological doses improved the abnormalities in BC and increased bone mineral density in men with adult-onset GHD, but discordant data were obtained for the bone effects in women. In conclusion, both GHD and GH excess are responsible for some well-defined alterations in metabolism, BC, bone mass, and joint physiology. Their normalization (by GH replacement or treatment of acromegaly) reverses most of these abnormalities, thus confirming their GH-related etiology.

RESUMO

This is a case report on a young woman with a large idiopathic unilateral adrenal hematoma (AH). Only few cases of AH which were not associated with any trauma, previous surgery, coagulative or any other systemic disorders have been described. The mass was discovered by abdominal ultrasound which was performed for a recent flank pain. Magnetic resonance imaging (MRI) confirmed the presence of a 13-cm sized lesion in the right hemi-abdomen; T1 and T2 weighed imaging was compatible with subacute-to-chronic adrenal hematoma. The lesion dislocated the liver and right kidney. Positron emission tomography (PET) did not show any significant radiotracer uptake by the mass. Serum cortisol, aldosterone, renin activity and DHEA-S were normal. Urinary catecholamines and free cortisol excretion were within the normal range too. The lesion was removed by transabdominal laparoscopic adrenalectomy without any complication. The histological exam confirmed a large subacute- to-chronic organized AH. In conclusion, in the absence of known risk factors, differential diagnosis of a large AH may not be easy. The possibility of an underlying pheochromocytoma, malignant adrenal or metastatic tumor must always be considered. In our patient, computed tomography (CT) scan and MRI suggested the presence of a large subacute-to-chronic AH, and PET excluded metabolic activity of the mass. Laparoscopic adrenalectomy can be the surgical treatment of choice in organized symptomatic AH. The correct diagnosis, early recognition and treatment of complications including adrenal insufficiency may decrease patient morbidity and mortality.

RESUMO

One of the most frequent consequences of allogeneic haemopoietic stem cell transplantation (allo-SCT) in both males and females is gonadal insufficiency. We report the case of a 27-year-old myelodysplastic male who developed azoospermia after allogeneic transplantation of haemopoietic stem cells from his HLA-identical sister. Post-transplant azoospermia was alternated with intermittent severe oligospermia. The patient had a normal endocrine pattern and evidence of mild chronic graft-versus-host disease (cGVHD). Normal intratesticular spermatogenesis was revealed by bilateral fine needle aspiration (FNA) cytology. Inflammation was evident at semen analysis, but no infection was detected by microbiological examination and sperm culture. These findings, together with the re-appearance of sperm cells at semen analysis after a low-dose immunosuppressive treatment, suggested the presence of cGVHD of the urogenital tract, causing a reversible obstruction of the spermatic tract and cryptozoospermia. This is the first case report documenting a severe impairment of sperm count because of a reversible obstruction of the seminal tract, likely caused by cGVHD, in a long-term survivor of allo-SCT with normal endocrine pattern. An important practical consequence of this case report is the fact that azoospermia was cured using low-dose immunosuppressive therapy, and this allowed us to avoid expensive stimulatory treatments with gonadotrophins, which remain, however, ineffective if the obstruction of spermatic tracts is not removed. A spontaneous uncomplicated pregnancy occurred in the partner of the patient 3 months after the corticosteroid treatment withdrawal.

RESUMO

Although thyroid disorders related to the end-stage renal disease (ESRD) are well known, there are discordant data on the function and morphology of the thyroid gland after renal transplantation (RT). The objective of this cross-sectional, case-control study was to investigate the prevalence and risk factors for disorders in the thyroid function and morphology after a successful RT. Fifty consecutive patients (25 females, 25 males) with fully functioning allograft were enrolled. Their age at transplant ranged from 23 to 44 yr (median, 38) and their post-RT follow-up lasted 15-86 months (median, 23). One hundred healthy subjects matched for sex, age and body mass index (BMI) were included as controls. Serum free thyroid hormones, TSH, thyroglobulin, thyroid hormone-binding globulin (TBG) and iodine urinary excretion were determined; ultrasonographic exam of the thyroid gland was performed in all subjects. Age, gender, time elapsed from RT, dialysis duration, kidney function, type of immunosuppression and corticosteroid dose were considered as possible influencing factors for the thyroid function. Hypothyroidism was found in 6% of patients, "low T3 syndrome" in 52%, while another 26% had free T3 (FT3), free T4 (FT4) and TSH in the lowest third of the normal range, suggesting inhibition of the whole hypothalamic-pituitary-thyroid (HPT) axis. Iodine excretion and prevalence of anti-thyroid antibodies were similar in both patients and controls. There was no significant difference in the thyroid function according to different immunosuppressive regimens. In patients, an ultrasonographic exam revealed a very variable thyroid volume ranging from 7.2 to 24.8 ml. Solid nodules were detected in 12 (24%) cases and cystic lesions in another four (8%); they were proven negative at cytological examination. Dialysis duration was longer in patients with thyroid nodules than in those without (p<0.05). Inhomogeneous hypoechoic pattern typical for chronic thyroiditis was more frequent than its biochemical expression. In conclusion, a high prevalence of abnormal thyroid morphology was found in patients after a successful RT, being partly related to a previous uremia. Abnormalities in the thyroid function are likely an expression of the post-transplant general and immunological conditions. Endocrinological follow-up is advisable in patients after RT, in order to discriminate thyroid dysfunctions which need specific treatments from those that can only be followed-up, avoiding inappropriate treatments of biochemical abnormalities.

RESUMO

Multiple endocrine neoplasm type 1 (MEN1) syndrome predisposes to the development of endocrine and non-endocrine tumors with an autosomal dominant pattern of inheritance. Different mutations have been found throughout the gene with a variable phenotype expression. The proband, a Caucasian man, was admitted to our department in 2001, at the age of 51 because of a 1-yr history of diarrhoea and hypertension. He reported a previous intestinal resection for bowel occlusion with a histological diagnosis of unspecified mesenchymal neoplasia. He had also undergone a left adrenalectomy for a large nonfunctioning adrenal adenoma. Subsequently, he had suffered from gastralgia and melena; a gastroduodenoscopy showed an erosive gastritis. His family history was negative for endocrine disorders. On physical examination, multiple abdominal cutaneous lipomas and facial angiofibromas were observed. Biochemical screening revealed a primary hyperparathyroidism and an increase in circulating levels of PRL, chromogranin-A, gastrin and glucagon. The whole body computed tomography (CT) scan, the 111In-octreotide scan and the pituitary magnetic resonance imaging (MRI) did not reveal any abnormality. The presence of small neuroendocrine tumors was suspected by a positron emission tomography uptake in the epigastric region. The endoscopic ultrasound revealed a pancreatic lesion sized 1.1 cm that is under evaluation. Direct DNA sequencing analysis of the proband MEN1 gene revealed the 579delG frameshift mutation in the exon 3. The genetic screening of the family revealed the same mutation in 3 out of 5 offspring. The biochemical screening revealed some features of the MEN1 syndrome in all three of them. In conclusion, a novel frameshift MEN1 mutation was found in kindred with an apparently negative family history. Our experience confirms that MEN1 syndrome is a complex and underestimated condition, unless specifically investigated by trained specialists.

RESUMO

Ovarian failure after allogeneic stem cell transplant (allo-SCT) is an important risk factor for development of osteoporosis. We investigated the effects of various antiresorptive treatments in long-term surviving females with ovarian failure after allo-SCT. A total of 60 women with osteoporosis or osteopenia were divided randomly into four groups of 15 women each. Group 1 was treated with calcium and vitamin D alone, group 2 received the same treatment in combination with hormone replacement therapy (HRT), group 3 received risedronate (35 mg weekly, orally for 1 year) and group 4 zoledronic acid (3 monthly doses of 4 mg (intravenous)). All groups were similar for age, body mass index, underlying disease and time elapsed from transplant. Lumbar and femoral bone mineral density (BMD) were measured at baseline and after 12 months, together with serum osteocalcin and urinary hydroxyproline. At 12 months, a significant decrease in lumbar and femoral BMD was observed in group 1 and a milder decrease in group 2. Risedronate treatment increased significantly lumbar BMD and prevented bone loss at the femoral neck. Zoledronic acid increased significantly both lumbar and femoral BMD. In groups 3 and 4 the hydroxyproline excretion was significantly reduced, while osteocalcin mildly increased only in group 4. In conclusion, bisphosphonate administration is useful to prevent and treat bone demineralization in young adult women after allo-SCT.

RESUMO

Neuroendocrine tumors represent a heterogeneous category of neoplasm, with conflicting diagnostic and therapeutic demands. We here describe the case of a 72-yr-old woman with evidence of a poorly differentiated small-cell neuroendocrine carcinoma (NEC) localized in different endocrine glands and other non-endocrine organs. In particular, a large ovarian mass, multinodular thyroid goiter, right adrenal mass, cystic liver metastases and anterior mediastinum lymph node metastasis were present. The largest thyroid nodule caused tracheal restriction and dyspnea. Diagnosis of poorly differentiated metastasized NEC of unknown origin was made on the basis of histological and immunohistochemical findings, and treatment with etoposide (100 mg/m2 in days 1, 2 and 3) and cisplatinum (45 mg/m2 in days 2 and 3) was initiated. Simultaneously, im administration of octreotide LAR 20 mg every 28 days was started, according to the presence of SS receptors at 111In-octreotide scan. Rapid improvement of dyspnea and a reduction of the largest thyroid nodule, liver metastases and adrenal mass by 50% were observed after 3 months of treatment; the dimensions remained stable thereafter, while the pericardial lymph node disappeared. In conclusion, poorly differentiated NEC of unknown primary site is a well-recognized category, usually with an aggressive behavior, rapid growth rate and wide dissemination. Median survival of these patients is 6 months if left untreated. Our patient is alive 18 months after beginning the treatment, reporting good general condition and quality of life over the whole follow-up period.

RESUMO

Osteoporosis is a common disorder, especially among elderly post-menopausal women. Elderly women are often affected by co-morbidities, impaired gastrointestinal function and reduced mobility; therefore, the treatment strategy for their osteoporosis can be difficult. In this randomized pilot study, we have investigated the effects of a 12-month treatment with neridronate on bone mineral density (BMD), bone turnover markers and quality of life (QoL). The study included 40 women (age, 65-80 yr; post-menopausal period, >15yr) from a single osteoporosis centre. Twenty women received a monthly im injection of 25 mg of neridronate associated with a daily dose of 500 mg of calcium and 400 U of vitamin D. Twenty women received calcium plus vitamin D supplements alone. Changes in BMD at the lumbar spine and femoral neck were measured by dual energy X-ray absorptiometry. Serum type I collagen C-telopeptide (sCTX), urinary free-deoxypyridinoline (ufDPD), bone alkaline phosphatase (ALP) and serum osteocalcin levels were determined. For the QoL assessment, the Italian version of the SF-36 test was administrated. Spine and hip BMD rose by 6.6 +/- 3 and 4.2 +/- 2.3%, respectively (p < 0.05), after 12 months of neridronate treatment. Markers of skeletal turnover significantly fell already after 3 months of neridronate treatment and decreased progressively thereafter within 12 months. The mean decrease at 12 months ranged from 38 +/- 11% for sCTX to 25.2 +/- 15% for ufDPD (p < 0.001, all). The mean improvement in QoL in the treated group was 45.7% for bodily pain, 37.5% for general health perception, 23.1% for vitality, 18% for emotional role functioning and 12% for physical role functioning. The changes observed in BMD, turnover markers and QoL in the untreated group were ns. The intermittent neridronate administration was easily manageable and well tolerated. In conclusion, neridronate currently represents a valid option for the treatment of osteoporosis, since it helps just as much as oral BPs in the improvement of BMD and in particular conditions it can be even more effective.

RESUMO

The physiological changes that the human body undergoes during aging are similar to those observed in GH deficiency (GHD). Early changes of aging are represented by increased fat mass, increased cardiovascular risk, reduced muscle mass and strength, reduced exercise tolerance, thinned skin, decreased strength and impaired quality of life. These observations led to hypothesize that the elderly could be GH deficient and would benefit from GH treatment. However, the effects of GH treatment in healthy elderly subjects by randomized and controlled studies are less promising than initially hypothesized. The etiopathology of age-related bone loss is multifactorial including menopause, andropause, somatopause and secondary hyperparathyroidism. GH has multiple effects on bone, either direct or mediated by IGF-I, stimulating osteoblast proliferation as well as osteoclast differentiation. Consequently, decline in GH secretion reduces bone turnover that causes osteopenia in young adults, but it has been hypothesized that it could protect against fractures in elderly subjects. The increase of bone remodeling achieved by GH therapy may be helpful in elderly men and women who have severely decreased bone turnover and impaired osteoblastic function. In conclusion, the endocrine pattern of aging is distinct from the decrease of GH/IGF-I levels associated with hypopituitarism. However, GH plays a role in metabolism and bone physiology throughout the human life span, although there is insufficient evidence for a clear therapeutic role of rhGH in aging. Thus, more data are needed to define the effects of somatopause to identify who could potentially benefit from the effects of somatotropic treatment.

RESUMO

BACKGROUND: We describe a multistep model of cancer genetic counselling designed to promote awareness, and disease surveillance and preventive measures for hereditary and familial breast and ovarian cancer. PATIENTS AND METHODS: Step T0 of the model entails information giving; this is followed by pedigree analysis and risk estimation (T1), risk communication and genetic testing (T2), and genetic test result communication (T3). User consent was required to proceed from one step to the next. Surveillance and preventive measures are proposed to at-risk users. Of the 311 subjects who requested cancer genetic counselling, consent data to each counselling step were available for 295: 93 were disease-free, 187 had breast cancer, 12 had ovarian cancer and three had breast plus ovarian cancer. RESULTS: Consent was high at T0 (98.39%), T1 (96.40%) and T2 (99.65%). Consent decreased at the crucial points of counselling: T2 (87.71%) and T3 [genetic test result communication (85.08%), and extension of counselling to and testing of relatives (65.36%)]. CONCLUSIONS: The model fosters the user's knowledge about cancer and favours identification of at-risk subjects. Furthermore, by promoting awareness about genetic testing and surveillance measures, the algorithm enables users to make a fully informed choice of action in case of predisposing or familial cancer risk.

RESUMO

A case of unusual combination of polycystic ovaries (PCO), adrenal non-functioning adenoma and severe hirsutism in a young woman from Southern Italy is reported here. A 18-yr-old woman was referred to our Department because of oligomenhorrea, acne and severe hirsutism. During evaluation of the cause of her symptoms, PCO and small left adrenal adenoma were revealed. Although adrenal androgen excess has been shown to dysregulate the hypothalamic-pituitary-gonadal axis, causing PCO-like syndrome, normal circulating androgen values were found. Androgens and cortisol levels were completely suppressed by low-dose dexamethasone test, excluding autonomous steroid secretion by the adrenal mass. Normal response of cortisol and adrenal androgens to corticotropin stimulation test permitted the exclusion of functional adrenal hyperandrogenism. Despite normal LH/FSH ratio, anovulatory cycles were revealed by persistently low progesterone values. Glucose and insulin response to oral glucose tolerance test did not differ from those of normal population. The patient showed an improvement of acne and hirsutism on therapy with estro-progestins (EP). In conclusion, despite normal pattern of serum androgens and LH/FSH ratio, this patient had anovulatory cycles and good response to the EP treatment. These findings suggest that ultrasonography evidence of PCO together with anovulatory cycles contributed to her clinical picture whereas adrenal adenoma seemed to have no relevant role. This case report underlines the need of cautious interpretation of imaging results and clinical signs of severe hirsutism, reminding one that the true cause of a medical problem may not be the most evident.
