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.

Incidentally discovered adrenal masses are mostly benign, asymptomatic lesions, often arbitrarily considered as nonfunctioning tumors. Recent studies, however, have reported increasing evidence that subtle cortisol production and abnormalities in the hypothalamic-pituitary-adrenal (HPA) axis are more frequent than previously thought. The purpose of this study was to investigate the clinical and hormonal features of patients with incidentally discovered adrenal adenomas, in relation to their clinical outcome. Fifty consecutive patients with incidentally detected adrenal adenomas, selected from a total of 65 cases of adrenal incidentalomas, were prospectively evaluated. All of them underwent abdominal computed tomography scan and hormonal assays of the HPA axis function: circadian rhythm of plasma cortisol and ACTH, urinary cortisol excretion, 17-hydroxyprogesterone, androgens, corticotropin stimulation test and low-dose (2 mg) dexamethasone test. The patients were reevaluated at regular intervals (6, 12, and 24 months) for a median period of 38 months. Subtle hypercortisolism, defined as abnormal response to at least 2 standard tests of the HPA axis function in the absence of clinical signs of Cushing's syndrome (CS), was defined as subclinical CS. Mild-to-severe hypertension was found in 24 of 50 (48%) patients, type-2 diabetes in 12 of 50 (24%), and glucose intolerance in 6 of 50 (12%) patients. Moreover, 18 of 50 patients (36%) were diffusely obese (body mass index, determined as weight/height2, > 25), and 14 patients (28%) had serum lipid concentration abnormalities (cholesterol > or = 6.21 mmol/L, low-density lipoprotein cholesterol > or = 4.14 mmol/L and/or triglycerides > or = 1.8 mmol/L). Compared with a healthy population, bone mineral density Z-score, determined by the DEXA technique, tended to be slightly (but not significantly) lower in patients with adrenal adenoma (-0.41 SD). Endocrine data were compared with 107 sex- and age-matched controls, and patients with adenomas were found to have heterogeneous hormonal abnormalities. In particular, significantly higher serum cortisol values (P < 0.001), lower ACTH concentration (P < 0.05), and impaired cortisol suppression by dexamethasone (P < 0.001) were observed. Moreover, in patients with adenomas, cortisol, 17-OH progesterone, and androstenedione responses to corticotropin were significantly increased (P < 0.001, all), whereas dehydroepiandrosterone sulfate levels were significantly lower at baseline, with blunted response to corticotropin (P < 0.001, both). However, the criteria for subclinical CS were met by 12 of 50 (24%) patients. Of these, 6 (50%) were diffusely obese, 11 (91.6%) had mild-to-severe hypertension, 5 (41.6%) had type-2 diabetes mellitus, and 6 (50%) had abnormal serum lipids. The clinical and hormonal features improved in all patients treated by adrenalectomy, but seemed unchanged in all those who did not undergo surgery (follow-up, 9 to 73 months), except for one, who was previously found as having nonfunctioning adenoma and then revealed to have subclinical CS. In conclusion, an unexpectedly high prevalence of subtle autonomous cortisol secretion, associated with high occurrence of hypertension, diabetes mellitus, elevated lipids, and diffuse obesity, was found in incidentally discovered adrenal adenomas. Although the pathological entity of a subclinical hypercortisolism state remained mostly stable in time during follow-up, hypertension, metabolic disorders, and hormonal abnormalities improved in all patients treated by adrenalectomy. These findings support the hypothesis that clinically silent hypercortisolism is probably not completely asymptomatic.

Background\ud \ud Cushing's disease is a rare endocrine disorder characterised by cortisol overproduction with severe complications. Therapies for cortisol reduction are often necessary. Here we report the outcomes from the pivotal phase III study of osilodrostat (a potent oral inhibitor of cytochrome P450 11B1, mitochondrial [11β-hydroxylase]; Novartis Pharma AG, Basel, Switzerland) in patients with Cushing's disease.\ud \ud \ud \ud Methods\ud \ud LINC 3 was a prospective, multicentre, open-label, phase III study with a double-blind randomised withdrawal period, that comprised four periods. Patients aged 18–75 years, with confirmed persistent or recurrent Cushing's disease (defined as mean 24-h urinary free cortisol [UFC] concentration >1·5 times the upper limit of normal [ULN] and morning plasma adrenocorticotropic hormone above the lower limit of normal) who had previously had pituitary surgery or irradiation, or were newly diagnosed and who refused surgery or were not surgical candidates, were recruited from 66 hospital sites and private clinical practices in 19 countries. In period 1, open-label osilodrostat was initiated in all participants and adjusted every 2 weeks (1–30 mg twice daily; film-coated tablets for oral administration) on the basis of mean 24-h UFC concentration and safety until week 12. In period 2, weeks 13–24, osilodrostat was continued at the therapeutic dose determined during period 1. In period 3, beginning at week 26, participants who had a mean 24-h UFC concentration of less than or equal to the ULN at week 24, without up-titration after week 12, were randomly assigned (1:1), via an interactive-response technology, stratified by osilodrostat dose at week 24 and history of pituitary irradiation, to continue osilodrostat or switch to placebo for 8 weeks. Participants and investigators were masked to treatment assignment. Ineligible participants continued open-label osilodrostat. In period 4, weeks 35–48, all participants were given open-label osilodrostat until core-study end. The primary objective was to compare the efficacy of osilodrostat versus placebo at the end of period 3. The primary endpoint was the proportion of participants who had been randomly assigned to treatment or placebo with a complete response (ie, mean 24-h UFC concentration of ≤ULN) at the end of the randomised withdrawal period (week 34), without up-titration during this period. The key secondary endpoint was the proportion of participants with a complete response at the end of the single-arm, open-label period (ie, period 2, week 24) without up-titration during weeks 13–24. Analysis was by intention-to-treat for all patients who received at least one dose of osilodrostat (full analysis set; key secondary endpoint) or randomised treatment (randomised analysis set; primary endpoint) and safety was assessed in all enrolled patients who received at least one dose of osilodrostat and had at least one post-baseline safety assessment. LINC 3 is registered with ClinicalTrials.gov, NCT02180217, and is now complete.\ud \ud \ud \ud Findings\ud \ud Between Nov 12, 2014, and March 22, 2017, 202 patients were screened and 137 were enrolled. The median age was 40·0 years (31·0–49·0) and 106 (77%) participants were female. 72 (53%) participants were eligible for randomisation during the withdrawal phase, of whom 36 were assigned to continue osilodrostat and 35 were assigned to placebo; one patient was not randomly assigned due to investigator decision and continued open-label osilodrostat. More patients maintained a complete response with osilodrostat versus with placebo at week 34 (31 [86%] vs ten [29%]; odds ratio 13·7 [95% CI 3·7–53·4]; p25% of participants) were nausea (57 [42%]), headache (46 [34%]), fatigue (39 [28%]), and adrenal insufficiency (38 [28%]). Hypocortisolism occurred in 70 (51%) patients and adverse events related to adrenal hormone precursors occurred in 58 (42%) patients. One patient died, unrelated to study drug, after the core study phase.\ud \ud \ud \ud Interpretation\ud \ud Twice-daily osilodrostat rapidly reduced mean 24-h UFC and sustained this reduction alongside improvements in clinical signs of hypercortisolism; it was also generally well tolerated. Osilodrostat is an effective new treatment option that is approved in Europe for the treatment of endogenous Cushing's syndrome and in the USA for Cushing's disease.

Purpose Clinical trials have demonstrated the favorable efficacy/safety profile of pasireotide in patients with Cushing’s disease (CD). We report interim long-term results of an ongoing real-world evidence study of subcutaneous pasireotide in patients with CD. Methods Adults with CD receiving pasireotide, initiated before (prior-use) or at study entry (new-use), were monitored for ≤ 3 years during a multicenter observational study (http://clinicaltrials.gov identifier NCT02310269). Primary objective was to assess long-term safety of pasireotide alone or with other CD therapies. Results At the time of this interim analysis, 127 patients had received pasireotide (new-use, n = 31; prior-use, n = 96). Eight patients had completed the 3-year observation period, 53 were ongoing, and 66 had discontinued. Among 31 new-use and 92 prior-use patients with ≥ 1 safety assessment, respectively: 24 (77%) and 37 (40%) had drug-related adverse events (AEs); 7 (23%) and 10 (11%) had serious drug-related AEs. Most common drug-related AEs were nausea (14%), hyperglycemia (11%) and diarrhea (11%); these were more frequently reported in new users and mostly of mild-to-moderate severity. 14 (45%) new-use and 15 (16%) prior-use patients experienced hyperglycemia-related AEs. Mean urinary free cortisol (mUFC) was within normal range at baseline and months 1, 12 and 24, respectively, in: 1/16 (6%), 9/18 (50%), 1/3 (33%) and 0/0 new users; 28/43 (65%), 15/27 (56%), 27/33 (82%) and 12/19 (63%) prior users. Conclusions Pasireotide is well tolerated and provides sustained reductions in mUFC during real-world treatment of CD. The lower rate of hyperglycemia-related AEs in prior users suggests that hyperglycemia tends not to deteriorate if effectively managed soon after onset. Clinical Trial Registration Number: NCT02310269.

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

Objective Monitoring of patients with Cushing’s disease on cortisol-lowering drugs is usually performed with urinary free cortisol (UFC). Late-night salivary cortisol (LNSC) has an established role in screening for hypercortisolism and can help to detect the loss of cortisol circadian rhythm. Less evidence exists regarding the usefulness of LNSC in monitoring pharmacological response in Cushing’s disease. Design Exploratory analysis evaluating LNSC during a Phase III study of long-acting pasireotide in Cushing’s disease (clinicaltrials.gov: NCT01374906). Methods Mean LNSC (mLNSC) was calculated from two samples, collected on the same days as the first two of three 24-h urine samples (used to calculate mean UFC [mUFC]). Clinical signs of hypercortisolism were evaluated over time. Results At baseline, 137 patients had evaluable mLNSC measurements; 91.2% had mLNSC exceeding the upper limit of normal (ULN; 3.2 nmol/L). Of patients with evaluable assessments at month 12 (n = 92), 17.4% had both mLNSC ≤ULN and mUFC ≤ULN; 22.8% had mLNSC ≤ULN, and 45.7% had mUFC ≤ULN. There was high variability in LNSC (intra-patient coefficient of variation (CV): 49.4%) and UFC (intra-patient CV: 39.2%). mLNSC levels decreased over 12 months of treatment and paralleled changes in mUFC. Moderate correlation was seen between mLNSC and mUFC (Spearman’s correlation: ρ = 0.50 [all time points pooled]). Greater improvements in systolic/diastolic blood pressure and weight were seen in patients with both mLNSC ≤ULN and mUFC ≤ULN. Conclusion mUFC and mLNSC are complementary measurements for monitoring treatment response in Cushing’s disease, with better clinical outcomes seen for patients in whom both mUFC and mLNSC are controlled.

BACKGROUND: Cushing's disease is a rare debilitating endocrine disorder for which few prospective interventional studies have been done. We report results of the first phase 3 trial assessing long-acting intramuscular pasireotide in patients with Cushing's disease. METHODS: In this phase 3 clinical trial we recruited patients aged 18 years or older with persistent, recurrent, or de-novo (non-surgical candidates) Cushing's disease who had a mean urinary free cortisol (mUFC) concentration (from three 24 h samples) of 1·5-5·0 times the upper limit of normal (ULN), a normal or greater than normal morning plasma adrenocorticotropic hormone concentration, and a pituitary source of Cushing's syndrome, from 57 sites across 19 countries. Exclusion criteria included previous pasireotide treatment, mitotane therapy within 6 months, and pituitary irradiation within 10 years. We randomly allocated patients 1:1 (block size of four) using an interactive-response-technology system to intramuscular pasireotide 10 mg or 30 mgevery 4 weeks for 12 months (in the core phase). We stratified randomisation by screening mUFC concentration (1·5 to

Objective The aim of this study was to evaluate the effects of estrogen-progestin therapy on serum levels of receptor-activating nuclear factor kappabeta ligand (RANKL), osteoprotegerin, osteocalcin, leptin, and ghrelin in a cross-sectional study of 99 healthy postmenopausal women conducted at the Menopause Clinic of our department. Design In this cross-sectional, observational study, 99 participants were divided into two groups. Group A was composed of 77 postmenopausal women who had never received estrogen-progestin therapy, and group B was composed of 22 postmenopausal women who had received transdermal 17beta-estradiol at a dose of 50 microg/day in a continuous regimen for at least 24 months and nomegestrol at a dose of 5 mg/day for 12 days/month in a sequential regimen. All participants underwent blood sampling in the morning and quantitative ultrasound bone-densitometry measurement of the proximal phalanges of the dominant hand. Results T score and amplitude-dependent speed of sound were significantly higher in group B than in group A. No significant differences in RANKL, osteoprotegerin, and osteocalcin were observed between the two groups. Serum leptin levels were significantly lower in group B than in group A, whereas ghrelin was significantly higher in group B than in group A. Conclusions The data gathered in this preliminary study indicate that estrogen-progestin therapy may protect against postmenopausal bone loss, but this protective effect does not seem to be exerted through action on the RANK-RANKL-osteoprotegerin system. Similarly, although several reports suggest that leptin and ghrelin are involved in bone metabolism, we could not detect any important correlation of these two hormones with bone metabolism or bone status in treated and untreated postmenopausal women. Because of the limited number of treated participants and the study design, the results of this preliminary study must be confirmed in larger, prospective, longitudinal studies.

This study was aimed at evaluating the effect of clothing style on bone mass and fractures in 70 postmenopausal nuns residing in a monastery in Naples. Sixty healthy women matched for age, body mass index, and menopausal status were enrolled as controls. Each participant underwent measurement by quantitative ultrasonometry (QUS) using a DBM Sonic Bone Profiler (IGEA S.p.A., Carpi, Modena, Italy) at proximal phalanges, responded to questionnaires regarding lifestyle, calcium intake, medical history, including clinical fragility fractures, and was submitted to routine biochemical assessment. A significant reduction in ultrasonometric parameters of bone mass was found in nuns compared with controls (p from 0.007 to

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

Herein we report on a young girl with recurrent, functioning paraganglioma of the organ of Zuckerkandl and severe and sustained arterial hypertension (systolic pressure > 200, diastolic pressure > 120 mmHg); with evidence of cardiac damage induced by chronic cathecolamine excess. She promptly and steadily improved after the institution of doxazosin (6 mg/day) plus atenolol (50 mg bid) treatment. This case demonstrates that a correct therapeutic strategy in the long-term management of patients with inoperable catecholamine-producing neuroendocrine tumors (pheochromocytomas and paragangliomas) can maintain arterial pressure in the normal range and reverse the cardiac damage induced by chronic cathecolamine excess.

Subclinical Cushing's syndrome (SCS) is increasingly being reported in incidentally discovered adrenal adenomas; its hallmark is mild autonomous cortisol hyperproduction without specific clinical signs of cortisol excess. Increased prevalence of hypertension, obesity, and impaired glucose tolerance have been described in SCS, but there is no specific study of the risk factors for cardiovascular diseases. In this cross-sectional study we assessed the cardiovascular profile in 28 consecutive SCS patients (19 women and 9 men; aged 56 +/- 10.6 yr) compared with 100 controls matched for age, gender, and body mass index. Systolic (P < 0.001) and diastolic (P < 0.005) blood pressures were higher in patients, as were fasting glucose, insulin, total cholesterol, triglycerides (all P < 0.001), and fibrinogen (P < 0.05). Moreover, the insulin resistance index was increased in patients as was the waist to hip ratio and mean carotid artery intima-media thickness (all P < 0.001). Of the patients, 60.7% had arterial hypertension, 71.4% had lipid abnormalities, 28.6% had impaired glucose tolerance, 35.7% type 2 diabetes mellitus, and 53.6% had abnormalities in hemostatic parameters. Atherosclerotic plaques were more frequent in patients (P < 0.0001). Only 4 (14.3%) patients did not have multiple risk factors for cardiovascular events. Six (21.3%) had clinical evidence of cardiovascular disease; another 11 (39.3%) had cardiovascular abnormalities as revealed by ultrasound scanning of carotid arteries and/or electrocardiogram records. These results strongly suggest that an increased cardiovascular risk profile, similar to that described in overt Cushing's syndrome, is present in SCS subjects. This finding supports the concept that chronic mild endogenous cortisol excess may have important systemic effects on the human body.

The etiologic diagnosis of hirsutism is often difficult. Previous studies have reported normal basal androgen and SHBG concentrations in 33-50% of hirsute women, suggesting the presence of an "idiopathic" form of hirsutism as the most frequent cause of this problem. The recent use of GnRH-analogues together with the corticotropin stimulation test allows better understanding of whether the cause of hirsutism is androgen excess and, if so, whether the origin of the latter is ovarian, adrenal or both. The present study evaluated adrenal and ovarian function in 48 young hirsute women as well as in 78 normal women matched for body mass index and age, who acted as control group. To determine ovarian function, a single 100-microg dose of GnRH analogue triptorelin was injected s.c.; thereafter, gonadotropins, 17-hydroxyprogesterone (17-OHP), delta4-androstenedione (delta4), total testosterone (T) and estradiol were determined. To better understand the adrenal function, 250 microg of 1,24 ACTH were administrated as i.v. infusion for 5 h, and plasma cortisol (F), 17-OHP, A4, DHEAS, T, 11-desossicortisol were measured. The combined use of these two stimulation tests was able to detect mild to moderate abnormalities in the steroidogenesis of ovaries alone (23%), adrenals alone (16.6%), or both (35.4%) in most hirsute women (75%) with otherwise normal baseline androgen concentrations. In particular, patients showed significantly increased responses of 17-OHP, delta4, total T, 11-desossicortisol, and F to 1,24-ACTH administration. Moreover, they also had significantly higher 17-OHP and T responses to triptorelin. In conclusion, milder forms of functional ovarian and/or adrenal hyperandrogenism, similar to those found in clearly hyperandrogenic women, were observed and could be an underlying mechanism of idiopathic hirsutism.

The pituitary-thyroid axis and neurohumoral activation indexes were simultaneously investigated in 16 in-patients hospitalized for cardiac heart failure (CHF), New York Heart Association (NYHA), class II-IV, and Killip clinical scale, class II-III, to evaluate their relationship with CHF morbidity and the relative prognostic value. At entry the patients were divided into two subgroups (A and B), according to the severity of CHF. Patients were further classified into two subgroups, according to the subsequent clinical course (C, poor outcome and D, improved clinical course). Blood samples were obtained every day for the radioimmunoassay measurement of plasma alpha-atrial natriuretic peptide (alphaANP), arginine vasopressin (AVP), and thyroid hormones, and the results were compared with those of 12 control subjects. At admission, alphaANP and 3,3',5'-triiodothyronine (rT3) values were higher, while 3,3',5-triiodothyronine (T3) to rT3 (T3/rT3) ratio was lower in subgroups A and B than in controls (p

The antiphospholipid syndrome is characterized by clinical evidence of arterial or venous thrombosis, thrombocytopaenia, recurrent fetal loss and repeated positivity of antiphospholipid autoantibodies. The association of antiphospholipid syndrome with the development of adrenal failure has been reported in more than 40 patients in the last 20 years, mostly due to bilateral cortical haemorrhage or thrombosis of adrenal vessels. The presence of antibodies against adrenal cortex was never documented in these patients. Here we report a case of recurrent thrombophlebitis, acute adrenal failure, and chronic hepatitis occurring in a young man found to have antiphospholipid antibodies and lupus anticoagulant. Autoantibodies against adrenal cortex were detected and abdominal ultrasonography showed morphologically normal adrenals. Mild thrombocytopaenia, Coomb's positive anaemia, increase in alanine- and aspartate-aminotransferases and increase in urinary protein excretion were found. Autoantibodies against liver/kidney microsomes were positive and liver biopsy was compatible with autoimmune hepatitis. The patient was treated with cortisone acetate, fludrocortisone and warfarin. Dilated cardiomyopathy was revealed one year later and coronarography did not document any occlusive coronary disease. Three years later, titres of autoantibodies, including those directed towards the adrenal cortex, were increased and others, previously absent, were detected. Nevertheless, the patient's clinical conditions seemed unchanged. At this time, an abdominal CT scan showed adrenal dysmorphisms with bilateral annular calcifications and central hypodensities suggesting previous bilateral adrenal haematomas. The hypercoagulable state that occurs in antiphospholipid syndrome can induce a localized inflammatory response generated by tissue injury, with a consequent release of intracellular antigens and antibodies production. Consequently, tissue-specific autoantibodies positivity may persist until the cells involved in antigen production are completely destroyed.

Percutaneous computed tomography-guided ethanol injection in aldosteroneproducing adrenocortical adenoma. Eur J Endocrinol 1995;132:302–5. ISSN 0804–4643 The feasibility, safety and effectiveness of percutaneous computed tomography-guided ethanol injection (PEI-CT) was investigated in a patient affected by aldosterone-producing adenoma (APA). A 42-year-old male patient with typical features of hyperaldosteronism presented a solitary left adrenal adenoma measuring 2 cm, with a normal contralateral gland, evidenced by both CT scan and adrenal [75Se-19]-nor-cholesterol scintigraphy. After normalization of potassium plasma levels, 4 ml of sterile 95% ethanol with 0.5 ml of 80% iothalamate sodium was injected. The procedure was completed in about 30 min. No severe pain or local complication was noted. Five hours after PEI, a fourfold and a twofold increase in aldosterone and cortisol plasma levels were observed, respectively. After 11 days on a normal sodium and potassium diet, normal potassium plasma levels and reduced aldosterone plasms levels were present, with reappearance of an aldosterone postural response. Plasma renin activity and aldosterone plasma levels normalized I month later, with reappearance also of a plasma renin activity postural response and maintenance of normal potassium plasma levels even on a high sodium and normal potassium diet. The patient has remained hypertensive, although lower antihypertensive drug dosages have been employed. After 17 months, normal biochemical, hormonal and morphological findings were still present. Thus, we suggest PEI-CT as a further alternative approach to surgery in the management of carefully selected patients with APA.
