    ABSTRACT: There are few long-term studies of cabergoline (CAB) administration in patients with macroprolactinomas. All of these studies included different type of patients, such as patients with idiopathic hyperprolactinemia, microprolactinomas and previously treated or untreated macroprolactinomas. We report a study of CAB treatment conducted exclusively in patients with newly diagnosed, untreated, macroprolactinomas. Twelve patients (6 M, 6 F) with macropolactinomas were investigated prospectively for 12 months to determine the effects of prolonged treatment with CAB on serum PRL levels, tumor size, visual fields and prevalence of side effects. Nine of these patients continued therapy and follow-up for 6 or more additional months of CAB administration. Our results demonstrated that CAB decreased the volume of the tumor in all patients investigated 3 months after the initiation of treatment. Specifically, mean tumor volume was 11,327 +/- 25,187 mm3 before the study and decreased to 4281 +/- 8465 mm3 and 1544 +/- 2118 mm3 in the second and last measurement, respectively. However, these changes were not statistically significant, most probably due to the very high SD. As far as the maximum diameter is concerned, mean values was 22.8 +/- 16.9 mm before the study and decreased to 16.6 +/- 10.9 mm and 13.4 +/- 7.5 mm in the 3 months and last examination, respectively. These changes were statistically significant (p = 0.005 and p = 0.007). The mean percentage decrease of the tumor volume and maximum tumor diameter was 42.4 +/- 14.0% and 24.7 +/- 4.8% respectively in the third month and 67.2 +/- 17.3% and 35.9 +/- 11.8% in the last estimation. These differences were statistically significant, (p < 0.01 and p < 0.001, respectively). The same was also true for PRL levels, the mean of which was 14,719 +/- 20,616 before treatment and became normal in the third month (153.3 +/- 63.4) and continued to be throughout the study. Four patients had visual field defects, which improved or even completely resolved during the treatment period. Finally, the CAB doses used were particularly small, i.e., 0.5-2 mg per week. All the patients recovered from their clinical problems and symptoms. This remarkable improvement was associated with an excellent tolerability of the long-term treatment due to the low incidence of side effects. In conclusion, the results of the present study demonstrated that CAB produced tumor shrinkage and normalized PRL levels in all the patients studied. Also, clinical symptoms disappeared and visual fields improved. These beneficial effects were associated with a very high compliance rate and minimal side effects. Thus, CAB can be considered a first-line pharmacological treatment of macroprolactinomas.

    ABSTRACT: Osteoporosis in childhood is uncommon, and it may be secondary to a spectrum of diverse conditions. When such causes have been excluded, some patients remain who have a congenital disease (osteoporosis imperfecta) or a disease in which the etiology is obscure, called idiopathic juvenile osteoporosis (IJO). The cause of IJO is unknown, and the diagnosis is based both on the exclusion of other diseases and on its own positive fractures. The basic strategy of treatment is to protect the spine until remission occurs. Sex steroids are contraindicated. Bisphosphonates, calcitriol, fluoride, and calcitonin have been administered therapeuticlly, but the results were equivocal. Usually the disease remits by itself.

    ABSTRACT: Recent clinical studies have suggested that women with polycystic ovarian syndrome (PCOS) may have disturbances of growth hormone (GH) kinetics and the GH/insulin-like growth factor (IGF)-I system. The knowledge that in various metabolic abnormalities there is a paradoxical sensitivity of pituitary somatotrophs to thyrotrophin releasing hormone (TRH) administration led to this investigation of the GH secretory response to TRH in women with PCOS. Twenty-four women with PCOS and 18 control women were studied. TRH was given as a single i.v. injection (time 0) and blood samples for GH measurements were obtained at -15, 0, 15, 30, 60 and 90 min. The GH responses were expressed as the area under the curve (AUC) or the differences from the basal value (Deltamax). The GH response to TRH (mean +/- SEM) was greater in women with PCOS (Deltamax 2.47 +/- 1. 73 versus 0.47 +/- 0.06 ng/ml, P < 0.05 and GH AUC 8.05 +/- 2.10 versus 2.58 +/- 0.18 ng/ml/90 min, P < 0.05). According to GH response to TRH, two PCOS subgroups were identified: (i) normal responders (n = 14) who showed Deltamax GH response (0.36 +/- 0.06 ng/ml)and GH AUC (1.93 +/- 0.64 ng/ml/90 min) similar to that in the controls and (ii) over-responders (n +/- 10) who showed a paradoxical increase in GH concentrations in response to TRH (Deltamax GH response 5.43 +/- 1.27 ng/ml and GH AUC 16.62 +/- 3.51 ng/ml per 90 min) that was significantly higher than in normally responding PCOS patients (P < 0.0001) or in controls (P < 0.0001). These data demonstrate an enhanced GH response to TRH administration in a subgroup of women with PCOS.

    ABSTRACT: To examine possible changes of leptin concentrations after the acute administration of glucose orally (OGTT). Seventy-five grams of glucose were administered per os in one group of obese and normal weight individuals and concentrations of glucose, insulin and leptin were measured at 0, 30, 60, 90 and 120 min. In an age matched control group of individuals with similar BMI water was given and leptin concentrations were measured before and after 30, 60, 90 and 120 min. Twenty-seven obese women aged 34+/-1.57 y with BMI 37.1+/-0.8 kg/m2 and 16 normal weight women, aged 32+/-1.13 y with BMI 23.6+/-0.3 kg/m2 formed the experimental group, while 10 obese and 10 normal weight females with similar age and BMI were used as controls. Weight, height, BMI, body fat, glucose, insulin and leptin at baseline and during OGTT. Variations of the above parameters were calculated from the area under the curve (AUC). Fasting leptin concentrations and AUC were higher in obese than in normal weight women. In obese women, leptin increased significantly in comparison to its basal concentrations 30 and 60 min after the glucose loading. Insulin was also increased, as expected. No correlation was found between insulin and leptin concentrations after glucose loading. Basal concentrations of leptin did not correlate with those of glucose and insulin. No changes in leptin concentrations were found in normal weight women after OGTT. However, a significant positive correlation was found between insulin and basal leptin. Finally, leptin concentrations did not change in obese and normal weight controls after water administration. A significant increase in leptin concentrations was found 30 and 60 min after glucose loading in obese individuals. No such increase was found in normal-weight women.

    ABSTRACT: Most thyroid textbooks describe hypothyroidism resulting in changes in the length of the menstrual cycle and in the amount of bleeding. Our experience at a busy thyroid clinic had given a picture which differs from that presented in the literature. The aim of this study was to determine the frequency and type of menstrual irregularities in premenopausal hypothyroid patients. We investigated the menstrual history, starting 6 months before the discovery of the disease, in 171 female premenopausal hypothyroid patients and 214 normal controls, with similar age and body mass index (BMI). TSH, TT4, TT3 and thyroid antibodies were measured by radioimmunoassay, while BMI was calculated from the ratio of body weight in kg to height in m2. Of the 171 hypothyroid patients, 131 (76.6%) had regular cycles and 40 (23.4%) irregular periods. Oligomenorrhoea and menorrhagia were the most common features in the latter group. No difference in BMI was found between the patients with or without menstrual abnormalities, or between patients and controls. TSH, TT4 and TT3 levels did not differ between patients with normal and abnormal menstruation. Forty-six (26.9%) out of 171 patients had subclinical hypothyroidism (group A), 42 (24.6%) mild hypothyroidism (group B) and 83 (48.5%) severe hypothyroidism (group C). Thirty-seven from group A (80.4%), 32 from group B (76.2%) and 62 from group C (74.7%) had normal periods. These differences were not statistically significant. Eighty-eight (88.9%) out of 99 patients in whom thyroid antibodies were measured had positive titres. Nineteen (21.6%) of the patients with positive thyroid antibodies had menstrual irregularities. This percentage did not differ from that found in the whole group of patients (23.4%). Out of 214 normal controls, 196 (91.6%) had normal menstruation and 19 (8.4%) irregular cycles. The latter group included mainly women with oligomenorrhoea. These data demonstrate that hypothyroidism in women is less frequently associated with menstrual disturbance than was previously described. Also, menstrual irregularities tend to be more frequent in sever hypothyroidism in comparison with mild cases, although this finding was not statistically significant. Oligomenorrhoea and menorrhagia are the most common menstrual disturbances.

    ABSTRACT: Until recently there was no imaging technique available which could demonstrate pathological changes in orbital tissues and could be regarded as a reliable measure of inflammation in thyroid eye disease (TED). Pentetreotide (a synthetic derivative of somatostatin) labelled with 111In has been used to localize tumours which possess surface or membrane receptors for somatostatin in vivo using a gamma camera (1). This technique visualizes somatostatin receptors in endocrine-related tumours in vivo and predicts the inhibitory effect of the somatostatin analogue octreotide on hormone secretion by the tumours (1). By applying 111In-DTPA-d-Phe octreotide scintigraphy (octreoscan), accumulation of the radionuclide was also detected in both the thyroid and orbit of patients with Graves' disease (2-4). If peak activity in the orbit 5h after injection of radiolabelled octreotide is set at 100%, a decrease to 40+/-4% is found at 24h, significantly different from the decrease in blood pool radioactivity, which is 15+/-4% at 24h. Accumulation of the radionuclide is most probably due to the presence in the orbital tissue of activated lymphocytes bearing somatostatin receptors (5). Alternative explanations are binding to receptors on other cell types (e.g. myoblasts, fibroblasts or endothelial cells) or local blood pooling due to venous stasis by the autoimmune orbital inflammation.

    ABSTRACT: We report the case of a giant prolactinoma in a 7-year-old boy, which was complicated by unilateral exophthalmos. The initial levels of prolactin (PRL) were about 80,000 microU/ml. Treatment with cabergoline (CAB) resulted in rapid normalization of serum PRL (6 weeks after initiation of treatment) and reduction of tumor size. In particular, magnetic resonance imaging (MRI), which was done 2.5 months after the patient was put on CAB, revealed tremendous improvement with a decrease in the size of the tumor which now showed no extrasellar extension. Subsequent MRI studies demonstrated further improvement. Exophthalmos, anisocoria and visual fields improved. In summary, this patient represents the first report of the therapeutic use of CAB as the primary mode of treatment in a 7-year-old boy with infiltrative giant prolactinoma complicated by unilateral exophthalmos. It is a noninvasive treatment that can preserve and restore vision, as well as pituitary function, and is preferable to surgery or radiation in the treatment of prolactin-secreting macroadenoma in childhood and adolescence.

    ABSTRACT: Octreotide, a potent synthetic long-acting somatostatin analogue, has been shown to have a beneficial effect in thyroid eye disease (TED). Orbital scintigraphy using ocetreoscan-111 is a useful study, which can be used to visualize somatostatin-receptor-bearing cells and also to select patients who might benefit from octreotide therapy. One major limitation of this therapy is that the drug must be administered parenterally and used several times daily. Lanreotide, a new somatostatin analogue, has a much longer duration of action in comparison with octreotide, and has recently been found to have a beneficial effect in the treatment of thyroid eye disease. The aim of this study was to investigate the orbital Indium-111-pentetreotide activity after treatment with octreotide and lanreotide in patients with thyroid ophthalmopathy. Fourteen patients were studied. 12 with bilateral and 2 with unilateral thyroid eye disease, (10 females and 4 males) and all with moderately severe symptoms of ophthalmopathy. All were treated with antithyroid drugs and were euthyroid at the time of the study. All patients were investigated with orbital scintigraphy using octreoscan-111 and selected for study on the basis of a positive octreoscan. Five patients received 30 mg lanreotide intramuscularly once every 2 weeks over a period of 3 months, and 5 patients received octreotide 100 microg subcutaneously thrice daily for 3 months. Four patients served as controls and received no treatment. The octreoscan-111 scintigraphy was repeated in all patients 3 months after the first examination. The NOSPECS classification and the clinical activity score (CAS) of thyroid ophthalmopathy were also evaluated before and 3 months after the initiation of treatment. All patients who received treatment had a negative follow-up octreoscan while controls had a positive octreoscan. NOSPECS score and CAS were improved with treatment, but unchanged in control patients. The reduced uptake of octreoscan may be the result of blocking of somatostatin receptors, or reduction in receptor-expressing tissues, downregulation of somatostatin receptors in target tissues, or a combination of these factors.

    ABSTRACT: Leptin, a product of the ob gene, is a 16 kDa protein which is produced by adipocytes. In humans, obesity is a common finding in women with polycystic ovary syndrome (PCOS). The role, however, of leptin in PCOS is not clear. Some studies have reported increased levels of leptin in PCOS, while others report that they are normal. Also, insulin resistance is a common finding in PCOS. The aim of this study was to investigate further the role of insulin in leptin secretion in patients with PCOS by treating them for 10 days with diazoxide, an insulin-reducing compound. Eight women with PCOS, mean age 22.1 +/- 2.7 years, with mean body mass index (BMI) 28.4 +/- 5.7kg/m2, were studied. An oral glucose tolerance test (OGTT) was performed in all women and blood samples were taken before and at 30, 60, 90, 120 and 150 min after the administration of glucose. Glucose, insulin, leptin, free testosterone, delta4 androstenedione, sex hormone binding globulin (SHBG), LH, FSH, IGF-I and insulin-like growth factor-binding protein-3 (IGFBP-3) were measured in the sera taken before the administration of glucose, while glucose and insulin levels were measured in all samples which were collected after the administration of glucose. Diazoxide 300 mg daily was given to all women starting after the end of the OGTT for 10 days. A second OGTT was performed the day after the discontinuation of the diazoxide treatment. The same hormonal and biochemical parameters were also measured in all patients during the second OGTT. After the administration of diazoxide a reduction in sum insulin (262 +/- 147 vs 679 +/- 341 microU/ml. P<().01), leptin (18.5 +/- 10.6 vs 24.2 +/- 10.2 ng/ml, P<0.01), free testosterone (3.0 +/- 1.9 vs 5.1 +/- 1.9 pg/ml, P<0.01), delta4 androstenedione (3.8 +/- 1.9 vs 5.7 +/- 2.0 ng/ml, P<0.01) and IGF-I (219.5 +/- 69.2 vs 314.5 +/- 82.3 ng/ml, P<0.01) levels was observed. Serum SHBG (38.8 +/- 16.8 vs 27.8 +/- 12.1 nmol/l, P<0.01) and sum glucose levels (994.1 +/- 252.7 vs 711.1 +/- 166.1 mg/dl, P<0.05) were increased while IGFBP-3 (3.96 +/- 2.49 vs 3.75 +/- 2.24mg/l), FSH (6.2 +/- 1.8 vs 6.0 +/- 2.5 mU/l) and LH (18.9 +/- 6.7 vs 21.4 +/- 6.7 mU/l) concentrations did not change significantly. A significant positive correlation was found between serum leptin and BMI values before and after administration of diazoxide as well as between leptin, insulin and IGFBP-3 values. Also, sum insulin values correlated significantly with BMI. However, when multiple regression analysis was used this correlation was eliminated except that between leptin and BMI. This was most probably due to the small number of cases. The mechanism of the reduction of leptin levels is unclear. However, it is suggested that the concomitant decrease of insulin levels may play a role.

    ABSTRACT: Recent studies have shown successful therapy with the long-acting somatostatin (SM) analogues octreotide and lanreotide in patients with thyroid eye disease (TED). In one such study it was also found that response to low-dose octreotide treatment (300 microg) in these patients was correctly predicted by [111In-DTPA-D-Phe1]-octreotide scintigraphy and concluded that this parameter should be used as a predictive test of the effectiveness of treatment with nonradioactive octreotide. It has also been suggested that octreoscan-111 may be seen as a parameter of disease activity in TED. However, it remains to be clarified whether octreoscan-111 predicts the therapeutic outcome better than the clinical activity score, or magnetic resonance imaging (MRI) or finally measurement of glucosaminoglycan (GAG) in the plasma and/or urine. The exact mechanism of action of SM analogues has not yet been fully clarified. Three explanations may be offered. First, SM suppresses insulin-like growth factor 1 (IGF-1) activity and inhibits IGF-1-mediated effects. A second possible mechanism could be the direct inhibition of the release of cytokines from T-lymphocytes, and finally, SM analogues may act on target cells through specific cell surface receptors. In view of the encouraging therapeutic results reported thus far in several studies, SM analogues may provide a valuable therapeutic alternative to corticosteroids, especially in patients who cannot tolerate the latter. However, further prospective, placebo-controlled studies with a large number of patients are needed before we can reach final conclusions.

    ABSTRACT: The suppression of the pituitary-gonadal axis by the administration of gonadotrophin-releasing hormone agonists (GnRH-a) is used occasionally as an adjunct therapy with gonadotrophins for ovulation induction in women with polycystic ovarian syndrome (PCOS). A number of recent clinical studies have suggested that women with polycystic ovaries (PCO) may have disturbances of normal growth hormone (GH) kinetics and alterations in the GH/insulin-like growth factor (IGF)-I system. The purpose of this study was to determine the effect of GnRH-a administration on GH-releasing hormone (GHRH)-stimulated GH release in women with PCOS. Eight women with PCO and six control women were studied before and after 2 months of treatment with the long acting GnRH-a triptoreline (3.75 mg monthly injections). GHRH was given as a single i.v. injection and blood samples for GH measurements were obtained at -15, 0, 30, 60, 90 and 120 min. The GH responses were expressed as the area under the curve (AUC) or the differences from the basal value (delta(max)). The GH response to GHRH (mean +/- SEM) was lower in women with PCO (AUC 114.9 +/- 43.1 versus 206.2 +/- 28.7 ng/ml/120 min, P < 0.05 and delta(max) 31.6 +/- 8.2 versus 49.4 +/- 5.8 ng/ml, P < 0.05). After treatment with the GnRH-a, the GH response to GHRH was significantly smaller than before treatment in both groups (PCO AUC 34.6 +/- 9.0 ng/ml/120 min and delta(max) 12.4 +/- 3.1 ng/ml; controls AUC 148.8 +/- 28.4 ng/ml/120 min and delta(max) 31.2 +/- 6.1 ng/ml), but the PCO group had a significantly smaller response. These data demonstrate that women with PCO have a reduced GH response to GHRH compared with normal controls and that GnRH-a administration causes a further GH reduction in both groups. Women with PCO have a greater suppression of GH response to GHRH during treatment with GnRH-a. This suggests that a different level of sensitivity in the somatotrophic axis exists in PCOS.

    ABSTRACT: Octreotide, a potent synthetic somatostatin (SM) analogue, was recently evaluated and found to have a beneficial effect in thyroid eye disease (TED), mostly in those patients with a positive Octreoscan-111. Lanreotide (LRT; Somatuline-Ipsen), a new SM long-acting analogue, is more active than natural SM and shows a much longer duration of action. The aim of the present preliminary study was to evaluate the therapeutic effect of LRT in the treatment of TED. Five patients, three males and two females, mean age 50.6 +/- 7.6 S.D. (45-64) years, all with severe symptoms of TED were studied. A similar number of patients, matched for age, sex and severity of ophthalmopathy served as controls. All the patients and controls were investigated with orbital scintigraphy using 111 In DTPA-D-Phe1-octreotide (Octreoscan-111) and selected on the basis of positive octreoscan. The NOSPECS system, as adapted by Donaldson et al. (Journal of Clinical Endocrinology and Metabolism 1973 37 276-285) and a disease activity score, as proposed recently by an International Workshop, have been followed in this study in order to evaluate the response to treatment. The five patients who comprised the treatment group received 0.04 g LRT i.m. once every 2 weeks over a period of 3 months, after which the Octreoscan-111 was repeated. The control patients were given an injection of water i.m., also once every 2 weeks for 3 months, after which they were evaluated clinically. No Octreoscan-111 was performed in the controls. All patients and controls were evaluated by the same physician, who was unaware of the type of treatment used. A decrease in the NOSPECS score and the clinical activity score was regarded as a positive response, while no change or an increase in the NOSPECS score along with no clinical improvement was regarded as a negative response. After 3 months of treatment with LRT, four patients showed a statistically significant improvement in ophthalmopathy in both eyes and one in one eye. Three of the control patients with TED did not show any change, one showed a minor improvement in one eye and no change in the other and one showed deterioration in both eyes. An interesting finding was that orbital Octreoscan-111 activity was absent in all the patients after LRT treatment. In conclusion, these preliminary results show that LRT has a beneficial effect on patients with TED, and that since it has to be given only once every 2 weeks, it is probably superior to any other form of SM treatment. However, as the number of patients was small, further studies are needed to confirm our results.

    ABSTRACT: Octreotide, a potent long-acting synthetic somatostatin analogue, has been reported to have a beneficial effect in thyroid eye disease (TED), but the precise mechanism of action remains unexplained. 111In-DTPA-D-Phe1-octreotide (Octreoscan-111) has been used to localize a number of endocrine tumours and visualize somatostatin receptors in the retrobulbar tissue of patients with TED. Furthermore, this technique can predict the inhibitory effect of octreotide on hormone secretion by endocrine tumours, as there is a close relation between the clinically observed inhibition and visualization of the tumour using Octreoscan-111. The aims of the present study were to confirm the beneficial effect of octreotide in patients with TED, to investigate the presence of somatostatin receptors in the orbital area and also, if possible, to ascertain whether this technique could select those patients with TED who might benefit from treatment with octreotide. A prospective study. An endocrine clinic of a national hospital. Twenty treated thyrotoxic patients with TED, 5 treated thyrotoxic patients without TED and 5 normal individuals were studied. In 12 patients with TED, 5 without TED and 5 normal individuals, Octreoscan-111 scintigraphy of the orbits was performed. The remaining 8 patients with ophthalmopathy served as controls. In patients with TED who were investigated with Octreoscan-111, 300 micrograms octreotide daily was given for 12 weeks. Six patients in both eyes and one patient in one eye showed an improvement in ocular manifestations as assessed by clinical criteria and changes in the NOSPECS score, while the rest showed no improvement. The patients who showed an improvement had a high number of somatostatin receptors and positive orbital scans, while with one exception the patients who did not respond had a low number of receptors and negative orbital scans (P < 0.02). None of the 5 patients without TED nor the normal individuals had a positive orbital scan. Seven out of 8 control patients with TED showed no change in the disease during the trial, while 1 deteriorated. We conclude that octreotide has a beneficial effect in thyroid eye disease and that Octreoscan-111 could predict those patients with thyroid eye disease who might benefit from this treatment.
