Diagnostic reliability of a single IGF-I measurement in 237 adults with total anterior hypopituitarism and severe GH deficiency.

OBJECTIVE: Within an appropriate clinical context, GH deficiency (GHD) in adults must be demonstrated biochemically by a single provocative test. Insulin-induced hypoglycaemia (ITT) and GH-releasing hormone (GHRH) + arginine (ARG) are indicated as the tests of choice, provided that appropriate cut-off limits are defined. Although IGF-I is the best marker of GH secretory status, its measurement is not considered a reliable diagnostic tool. In fact, considerable overlap between GHD and normal subjects is present, at least when patients with suspected GHD are considered independently of the existence of other anterior pituitary defects. Considering the time and cost associated with provocative testing procedures, we aimed to re-evaluate the diagnostic power of IGF-I measurement. DESIGN: To this goal, in a large population [n = 237, 139 men, 98 women, age range 20-80 years, body mass index (BMI) range 26.4 +/- 4.3 kg/m2] of well-nourished adults with total anterior pituitary deficit including severe GHD (as shown by a GH peak below the 1st centile limit of normal response to GHRH + ARG tests and/or ITT) we evaluated the diagnostic value of a single total IGF-I measurement. IGF-I levels in hypopituitary patients were evaluated based on age-related normative values in a large population of normal subjects (423 ns, 144 men and 279 women, age range 20-80 years, BMI range 18.2-24.9 kg/m2). RESULTS: Mean IGF-I levels in GHD were lower than those in normal subjects in each decade, but not the oldest one (74.4 +/- 48.9 vs. 243.9 +/- 86.7 micro g/l for 20-30 years; 81.8 +/- 46.5 vs. 217.2 +/- 56.9 micro g/l for 31-40 years; 85.8 +/- 42.1 vs. 168.5 +/- 69.9 micro g/l for 41-50 years; 82.3 +/- 39.3 vs. 164.3 +/- 60.3 micro g/l for 51-60 years; 67.5 +/- 31.8 vs. 123.9 +/- 50.0 micro g/l for 61-70 years; P < 0.0001; 54.3 +/- 33.6 vs. 91.6 +/- 53.5 micro g/l for 71-80 years, P = ns). Individual IGF-I levels in GHD were below the age-related 3rd and 25th centile limits in 70.6% and 97.63% of patients below 40 years and in 34.9% and 77.8% of the remaining patients up to the 8th decade, respectively. CONCLUSIONS: Total IGF-I levels are often normal even in patients with total anterior hypopituitarism but this does not rule out severe GHD that therefore ought to be verified by provocative testing of GH secretion. However, despite the low diagnostic sensitivity of this parameter, very low levels of total IGF-I can be considered definitive evidence of severe GHD in a remarkable percentage of total anterior hypopituitary patients who could therefore skip provocative testing of GH secretion.

Surgical treatment and clinical outcome of GH-secreting adenomas in elderly patients.

Patients older than 65 years represent 3-5% of all acromegalic patients. The old age of the patients and the higher incidence of cardiovascular and metabolic complications related to acromegaly could increase the intra- and peri-operative risk, so that medical treatment is usually recommended as a therapy of choice. The aim of this retrospective study was to investigate the impact of transsphenoidal surgery in a series of 22 elderly patients with active acromegaly, with special regard to anaesthesiological risk, peri-operative complications, and clinical outcome. Despite an increased anesthesiological risk being present in 16/22 patients, no complication occurred during surgery. Similarly, no post-operative mortality or major complications were observed. Biochemical cure, defined at 6 months by glucose-suppressed plasma GH levels below 1 ng/ml and normal age-corrected IGF-I value levels, was achieved in 68% of patients and no recurrence of disease was observed in the subsequent follow-up (mean 5.2+/-2.1 years). A significant cardiovascular improvement was observed in cured patients, with a decrease of left ventricular mass index (91.3+/-20.1 vs 115.9+/-15.0 g/m(2); P<0.005), as measured by echocardiography, as well as a slight but significant decrease of systolic and diastolic blood pressure values (130.0+/-12.1 mmHg vs 137.6+/-13.5 mmHg P<0.05; and 84.2+/-6.4 mmHg vs 88.8+/-7.5 mmHg P<0.05, respectively). A significant post-operative improvement of glucose tolerance was also observed in this group. We conclude that transsphenoidal surgery, if well planned and carefully performed, is safe and able to induce a significant cardiovascular and metabolic improvement even in elderly acromegalic patients.

Relationship between blood pressure and glucose tolerance in acromegaly.

BACKGROUND: Hypertension represents a well-known risk factor for cardiovascular diseases. The pathogenesis of hypertension in acromegaly is commonly viewed as multifactorial, but the possible influence of metabolic disorders on blood pressure (BP) in affected patients is largely unknown. OBJECTIVE: The aim of the present study was to evaluate the impact of glucose metabolism abnormalities on BP values in a series of patients with active acromegaly. DESIGN: An open multicentre prospective study. PATIENTS: Sixty-eight patients with active disease, aged 47.5 +/- 11.7 years, have been studied. Thirty-nine had normal glucose tolerance (NGT), 16 impaired glucose tolerance (IGT) and 13 suffered from diabetes mellitus (DM). MEASUREMENTS: Mean clinical BP values were calculated as the mean of BP values obtained by sphygmomanometric measurement in three separate occasions and mean 24-h, diurnal and nocturnal systolic (SBP) and diastolic (DBP) values were obtained by 24-h ambulatory blood pressure monitoring (ABPM). RESULTS: Patient's age and the degree of glucose tolerance abnormalities were found to significantly and independently influence BP values. All clinical and ABPM SBP and DBP values significantly increased with age by linear regression (P < 0.02 for all BP values, 0.30 < or = R < or = 0.43), and the independent influence of this parameter on BP values was confirmed by mutivariate analysis. Similarly, the independent influence of glucose tolerance abnormalities on BP values was confirmed when introducing age as a covariable in a multivariate analysis, and patients with DM presented significantly higher clinical SBP and 24-h, diurnal and nocturnal SBP and DBP than patients with NGT (P < 0.02 for clinical SBP, P < 0.015 for all ABPM values, respectively). In addition, patients with DM showed significantly higher 24-h, diurnal and nocturnal DBP than those with IGT (P < 0.05 in all cases). In contrast, no significant difference was found between NGT and IGT patients. No significant influence of disease duration, BMI, GH, IGF-I, or fasting and 2-h post glucose load insulinaemia on BP values was observed. CONCLUSIONS: Abnormalities of glucose metabolism significantly contribute to increase systolic blood pressure and especially diastolic blood pressure in acromegalic patients. Careful control of blood pressure and of risk factors for developing systemic hypertension, with special reference to glucose tolerance, is mandatory to decrease cardiovascular morbidity and mortality in such patients.

Marked improvement in cardiovascular function after successful transsphenoidal surgery in acromegalic patients.

OBJECTIVE: Transsphenoidal surgery results in biochemical remission of acromegaly in 45-80% of patients; however, few studies have addressed the impact of transsphenoidal surgery on cardiovascular function in acromegalic patients. The aim of this prospective study was to investigate the effects of postoperative GH/IGF-I normalization on echocardiographic parameters and blood pressure (BP) in a series of patients with active acromegaly. DESIGN: An open prospective study. PATIENTS: Thirty newly diagnosed acromegalic patients undergoing transsphenoidal surgery. MEASUREMENTS: Doppler echocardiography and 24-h ambulatory blood pressure monitoring were performed before and 6 months after transsphenoidal surgery. RESULTS: Fifteen patients were considered to be well controlled postoperatively (group A), as defined by normal age-corrected IGF-I levels and glucose-suppressed GH levels less than 2 mU/l, the remaining 15 patients being considered as poorly controlled (group B). In group A, a postoperative decrease of left ventricular mass index was observed (104.4 +/- 6.6 vs. 127.1 +/- 7.7 g/m2; P < 0.001), associated with an improvement of some indices of diastolic function, such as an increase of the early/late transmitral peak flow velocity (P < 0.05) and a decrease of isovolumic relaxation time (P < 0.01). No significant change was observed in group B. A significant decrease of 24-h systolic BP was also observed in group A (P < 0.05) and five of six patients normalized their BP circadian rythm. In contrast, a nonsignificant increase in BP values, with a persistent blunted BP profile where present, was observed in group B. CONCLUSIONS: We conclude that successful transsphenoidal surgery is able to induce a significant improvement in some cardiac parameters and a slight reduction in systolic blood pressure in acromegalic patients.

Guidelines for diagnosis and therapy of MEN type 1 and type 2.

This is a consensus statement from an international group, mostly of clinical endocrinologists. MEN1 and MEN2 are hereditary cancer syndromes. The commonest tumors secrete PTH or gastrin in MEN1, and calcitonin or catecholamines in MEN2. Management strategies improved after the discoveries of their genes. MEN1 has no clear syndromic variants. Tumor monitoring in MEN1 carriers includes biochemical tests yearly and imaging tests less often. Neck surgery includes subtotal or total parathyroidectomy, parathyroid cryopreservation, and thymectomy. Proton pump inhibitors or somatostatin analogs are the main management for oversecretion of entero-pancreatic hormones, except insulin. The roles for surgery of most entero-pancreatic tumors present several controversies: exclusion of most operations on gastrinomas and indications for surgery on other tumors. Each MEN1 family probably has an inactivating MEN1 germline mutation. Testing for a germline MEN1 mutation gives useful information, but rarely mandates an intervention. The most distinctive MEN2 variants are MEN2A, MEN2B, and familial medullary thyroid cancer (MTC). They vary in aggressiveness of MTC and spectrum of disturbed organs. Mortality in MEN2 is greater from MTC than from pheochromocytoma. Thyroidectomy, during childhood if possible, is the goal in all MEN2 carriers to prevent or cure MTC. Each MEN2 index case probably has an activating germline RET mutation. RET testing has replaced calcitonin testing to diagnose the MEN2 carrier state. The specific RET codon mutation correlates with the MEN2 syndromic variant, the age of onset of MTC, and the aggressiveness of MTC; consequently, that mutation should guide major management decisions, such as whether and when to perform thyroidectomy.

Two familial giant pituitary adenomas associated with overweight: clinical, morphological and genetic features.

OBJECTIVE: Pituitary adenomas are usually sporadic, although rare familial cases have been described. Here we report two first degree female cousins with giant pituitary adenoma and overweight. Both presented with secondary amenorrhoea, occasional headache and weight gain. MATERIALS AND METHODS: In both patients clinical, morphological and genetic studies were performed. Both patients underwent surgery and post-operative medical therapy with somatostatin analogues and dopamine agonist, followed by a conventional radiotherapy course. RESULTS: Clinical examination at presentation revealed an acromegaloid habitus only in the second patient. Basal and dynamic hormonal evaluation showed high serum GH and serum IGF-I values, higher in the second than in the first patient, and a mild hyperprolactinaemia only in the first patient. On optical and electron microscopy, both tumours were oncocytic adenomas, immunopositive for GH in the first patient and GH/prolactin in the second. The genetic analysis for germ-line mutations of the multiple endocrine neoplasia type 1 gene was negative. Two years after radiotherapy a remarkable shrinkage of both tumours was observed, whereas the overweight worsened in both patients, accompanied by high plasma leptin values. CONCLUSION: To our knowledge, this is the first report of familial pituitary adenomas including one case of a clinically silent GH-secreting adenoma. In addition, it provides further evidence that familial pituitary tumours can occur as a multiple endocrine neoplasia type 1 unrelated disease.

Adrenomedullin, a new peptide, in patients with insulinoma.

BACKGROUND: It has been demonstrated that adrenomedullin, a newly discovered peptide, affects the release of insulin from pancreatic islets cells, suggesting a role in the insulin-regulating system. OBJECTIVE: To investigate whether adrenomedullin secretion is modified in patients with insulin-secreting islet cell tumours. DESIGN: The study was performed in nine patients with surgically treated insulinoma. Circulating adrenomedullin was assayed using a specific radioimmunoassay and its localization and distribution in the tumour were determined by means of immunohistochemistry. RESULTS: Adrenomedullin concentrations were significantly greater in patients with insulinoma (6.6 +/- 3.2 fmol/ml) than in controls (2.1 +/- 1.1 fmol/ml). In six patients monitored before and after surgery, plasma adrenomedullin decreased from 6.3 +/- 2.9 fmol/ml to 3.0 +/- 1.6 fmol/ml. Immunoreactive adrenomedullin was localized exclusively in the tumours cells, whereas stroma, surrounding pancreas parenchyma and major ducts were negative for the peptide. CONCLUSIONS: Our findings indicate that circulating adrenomedullin is increased in insulinoma and that this increase is related to the neoplastic phenotype.

Physiology and possible pathology of growth hormone secretagogues.

Growth hormone segretagogues (GHS) are artificial molecules able to stimulate growth hormone (GH) secretion. They were discovered before the hypothalamic growth hormone-releasing hormone (GHRH). These molecules had a structure devoid of opiate activity, and GHRP-6 is the most representative compound. These compounds identified a new physiological system involved in GH regulation, and their action is independent of GHRH or somatostatin. Recently an endogenous ligand for the GHS receptor, ghrelin, was discovered, suggesting that this may be the third factor in the control of GH secretion. This peptide was isolated from the stomach and is characterized by the presence of an acylated group representing a new type of molecular hormonal structure; it is able to stimulate GH secretion in vitro and in vivo in the rat. As observed for the majority of GHS, ghrelin's action is not fully specific for GH release; the acute administration of ghrelin stimulates the release of significant amounts of PRL, ACTH and cortisol. Moreover, the presence of ghrelin in rat and human placenta has been reported, suggesting a possible role of this peptide in the local modulation of GH release and in maternal and fetal pituitary secretion. Ghrelin stimulates gastric acid secretion, is able to induce adiposity by activating a central mechanism for increasing food intake and decreasing fat utilization, and ghrelin mRNA and peptide are expressed in normal and adenomatous human pituitary tissue. Possible therapeutic applications of ghrelin remain to be assessed.

Systemic hypertension and impaired glucose tolerance are independently correlated to the severity of the acromegalic cardiomyopathy.

Increased mortality from cardiovascular diseases has been reported in acromegaly. Our objective was to evaluate the impact of glucose tolerance abnormalities and/or systemic hypertension in further worsening the acromegalic cardiomyopathy. The study design was open transversal. The subjects studied were 130 consecutive naive acromegalic patients (74 women and 56 men; age, 17-80 yr). Interventricular septum (IST) and left ventricular (LV) posterior wall thickness (PWT), LV mass index (LVMi), maximal early to late diastolic flow velocity ratio (E/A), isovolumic relaxation time (IRT), and LV ejection fraction (EF) were measured by echocardiography. The results were analyzed in line with the presence of glucose tolerance abnormalities (normal in 60, impaired in 38, diabetes mellitus in 32) and the presence (in 46) or absence (in 84) of hypertension. Patients with impaired glucose tolerance and diabetes mellitus had significantly higher age (P = 0.01), and systolic (P = 0.01) and diastolic (P = 0.01) blood pressures and lower E/A (P = 0.01) and EF (P = 0.01) than those with normal glucose tolerance. Disease duration, circulating GH and insulin-like growth factor I (IGF-I) levels, IST, LVPWT, LVMi, and IRT were similar in the 3 groups. Normotensive patients had significantly lower age (P<0.001), LVPWT (P<0.001), IST (P = 0.003), LVMi (P<0.001), and IRT (P = 0.02) and significantly higher E/A (P<0.001) and EF (P<0.001) than hypertensive subjects. Disease duration, circulating GH, and IGF-I levels were similar in the 2 groups. Multiple regression analysis showed that systolic blood pressure was the strongest predictor of LVMi (P = 0.0004), followed by GH levels (P = 0.02), whereas diastolic blood pressure was the strongest predictor of LVEF reduction (P<0.0001), followed by glucose tolerance status (P = 0.02). Age was the strongest predictor of both E/A impairment (P<0.0001) and IRT (P = 0.01), followed by IGF-I levels (P = 0.02). Compared to patients with uncomplicated acromegaly, those with hypertension but without abnormalities of glucose tolerance had an increased prevalence of LV hypertrophy (75% vs. 37.2%) as well as of impaired diastolic (50% vs. 7.8%) and systolic function (18.7% vs. 3.9%), whereas patients with glucose tolerance abnormalities but without hypertension had only an increased prevalence of impaired diastolic (39.7%) and systolic function (31.7%). The subgroup of acromegalic patients suffering from hypertension and diabetes mellitus had the highest prevalence of LV hypertrophy (84.6%), diastolic filling abnormalities (69.2%), and impaired systolic function at rest (53.9%). A careful cardiac investigation should thus be performed in all acromegalic patients showing these complications.

Two-year follow-up of acromegalic patients treated with slow release lanreotide (30 mg).

Pharmacotherapy of acromegaly has been improved in recent years as new long-acting somatostatin analogs have became available; they have been suggested as an alternative treatment to pituitary surgery and radiotherapy. To avoid the inconvenience of multiple daily injections during long-term therapy, a slow release formulation of lanreotide (LAN), to be administered im at a dose of 30 mg every 7-14 days, has been introduced in the therapeutic management. The suppressive effects of a short-term LAN treatment on GH and insulin-like growth factor I (IGF-I) hypersecretion were shown to be similar to those obtained with sc octreotide. However, scant data have been reported concerning a long-term treatment with this drug. In the present study the efficacy and tolerability of a 24-month LAN treatment were evaluated in 118 active acromegalic patients; 71 had been previously operated on and treated with s.c. octreotide (operated patients), 24 previously operated on had been irradiated and treated with s.c. octreotide (irradiated patients), and the remaining 23 were newly diagnosed (de novo patients). The efficacy was considered on the basis of controlled GH (fasting, <7.5 mU/L; glucose-suppressed, <3.0 mU/L) and IGF-I (age-adjusted normal values) secretion. In the 118 patients as a whole, circulating GH and IGF-I levels were significantly decreased during the 24-month LAN treatment (P < 0.0005 at all time points vs. basal value). After 24 months of therapy, controlled GH and IGF-I levels were achieved in 64%, 37%, and 78% and in 51%, 37%, and 70% of operated, irradiated, and de novo patients, respectively. A reduction in tumor size was documented in 5 of 23 de novo patients (22%). Among the 84 operated/irradiated with evident tumor remnant, significant shrinkage was documented in 5 patients (5.9%). Treatment was well tolerated by the majority of patients. Only 2 patients (1.7%) withdrew from LAN treatment due to severe side effects. In conclusion, a 24-month treatment with slow release lanreotide (30 mg) is effective in reducing GH and IGF-I levels; furthermore, in de novo patients it induces disease control in 70% of patients and causes tumor shrinkage in 22% of them, with excellent compliance. These data suggest that LAN can be used in long-term treatment of acromegalic patients.

p16 (INK4a, MTS-1) gene polymorphism and methylation status in human pituitary tumours.

OBJECTIVE: The p16 gene, which encodes a physiological inhibitor of the cyclin D-CDK4 complex, is now considered as an important tumour-suppressor gene in a variety of tumours. A marked reduction of its expression has been reported to occur without significant genetic alterations in human pituitary adenomas, although rare point mutations of uncertain functional significance have been described. On the other hand, p16 gene silencing due to hypermethylation has been reported in several human primary tumours. The aim of this study was to further investigate the pathogenetic events leading to p16 gene inactivation in pituitary tumours. DESIGN: To screen a european series of human pituitary tumours for p16 gene alterations and possible gene hypermethylation. PATIENTS: A representative series of 31 human pituitary tumours-30 macroadenomas, including a MEN-1 non-secreting pituitary adenoma and a non-MEN-1 familial giant GH-secreting adenoma, and one FSH-secreting pituitary carcinoma-was studied. METHODS: Polymerase chain reaction/single strand conformation polymorphism (PCR-SSCP) analysis was used to screen for p16 gene alterations in all cases. Direct sequencing of PCR-products was obtained by the di-deoxynucleotide method where suspected abnormalities of the PCR-SSCP analysis were observed. In 24 samples, a methylation-specific PCR assay (MSP-PCR) was used to determine p16 gene methylation status. RESULTS: Two sporadic cases of pituitary adenomas had a similar single A to G base substitution leading to an heterozygous Ala140Thr p16 polymorphism, which has not previously been described in such tumours, but is known to be functionally silent. No other p16 abnormality could be suspected from PCR-SSCP analysis in this series. In contrast, the presence of methylated-specific PCR products was observed in 20/24 cases (83.3%). CONCLUSIONS: This study confirms that p16 gene mutations are not involved in the pathogenesis of human pituitary tumours, although polymorphisms can be demonstrated, depending on the population considered. In contrast, the high incidence of hypermethylation of the p16 gene suggests that such an alteration occurs early in pituitary tumours, and may play a role in pituitary tumorigenesis.

Comparison of six months therapy with octreotide versus lanreotide in acromegalic patients: a retrospective study.

OBJECTIVE: We analysed the effects of 6-months' treatment with octreotide s.c. and lanreotide-SR on circulating GH and IGF-I levels in acromegaly. DESIGN: Open retrospective study. PATIENTS: Thirty-eight patients with active acromegaly (plasma IGF-I levels greater than 2 standard deviations for age-matched controls and increased serum GH levels not suppressible by oral glucose load) were studied. All patients received s.c. octreotide at a dose of 150-600 microg/day for six months as first therapy and subsequently, lanreotide i.m., 30-60 mg either at 14 or 10 day intervals, for 6 months. A 3 months' washout was applied before starting lanreotide treatment. MEASUREMENTS: Mean serum GH levels (from three samples), IGF-I, and clinical examination were performed before and 30, 60, 90 and 180 days after octreotide and lanreotide treatments. Safety tests, HbA1c and, thyroid function were evaluated every three months. RESULTS: Circulating GH and IGF-I levels were significantly reduced (P < 0.001) after one, three and six months of both octreotide and lanreotide treatment. The absolute values were lower and the percent decrease in serum GH levels obtained after octreotide treatment was significantly greater, at all scheduled assessments, than after lanreotide (P < 0.01). Serum IGF-I levels during octreotide were significantly lower only after the first month of therapy (P < 0.01). CONCLUSIONS: Our study shows that octreotide s.c. is able to induce an earlier reduction in IGF-I levels and a more marked reduction in GH levels than lanreotide. However, after six months of therapy the number of patients with safe GH levels and normal IGF-I age-matched levels, was similar with both drugs. Therefore we suggest that octreotide treatment be preferentially used in the short-term presurgical treatment, while lanreotide can be used in chronic therapy when better compliance is necessary.

Cardiac effects of slow-release lanreotide, a slow-release somatostatin analog, in acromegalic patients.

Cardiac involvement, mostly characterized by left ventricular hypertrophy associated with various degrees of cardiac dysfunction, greatly contributes to the increased mortality and morbidity observed in acromegaly. Lanreotide is a new SRIF analog characterized by a slow-release (SR) formulation with the peculiarity of a 30-mg im administration every 10-14 days. In this study, 13 patients with postoperative active acromegaly (9 females, 4 males, 45.9 +/- 16.3 yr old) underwent an echo-Doppler and hormonal study before and during a 12-month period of treatment with SR-lanreotide. GH and insulin-like growth factor I plasma levels (mean +/- SD) decreased significantly throughout the study period (from 10.1 +/- 2.2 to 3.9 +/- 0.9 ng/mL for GH, P < 0.005; and from 511.0 +/- 33.0 to 305.0 +/- 34.2 ng/mL for insulin-like growth factor I, P < 0.0001). Left ventricular mass index (mean +/- SD, 137.1 +/- 7.5 g/m2 at baseline) decreased after 3 months (120.0 +/- 5.4 g/m2), 6 months (111.7 +/- 5.7 g/m2), and 12 months (110.3 +/- 5.2 g/m2) of treatment (P < 0.005 at each time-point). This reduction in left ventricular mass index was accompanied by an improvement in some indexes of left ventricular diastolic function, especially the isovolumetric relaxation time (mean +/- SD, 109.1 +/- 4.6 m/sec at baseline), which decreased after 3 months (91.9 +/- 2.8 m/sec), 6 months (92.3 +/- 3.2 m/sec), and 12 months (92.2 +/- 3.0 m/sec) of treatment (P < 0.005 at each time-point). We conclude that SR-lanreotide is able to improve cardiac morphology and functional abnormalities in acromegaly; whether such beneficial effects on cardiac parameters will contribute to improve life expectancy in these patients should be further investigated.
