Abstract
1 Background: The ESE-ENSAT guidelines on ACC management suggest adjuvant mitotane for patients at high risk of recurrence. This indication has limited evidence base, lacking results from randomized controlled trials. No suggestion for or against adjuvant mitotane in low-risk patients was given, since studies did not stratify patients for prognosis. The randomized controlled study ADIUVO compared the efficacy of adjuvant mitotane treatment vs. observation in prolonging recurrence-free survival (RFS) in patients at low-intermediate risk of recurrence. Methods: The main inclusion criteria were: stage I-III ACC, R0 surgery, and Ki-67 ≤10%. Patients were randomly assigned 1:1 to adjuvant mitotane or observation. The primary endpoint of the study was RFS. Patients who refused randomization were eligible for the ADIUVO OBSERVATIONAL study. In this prospective, observational study, patients were managed as in ADIUVO except for randomization. A total of 91 patients were enrolled in ADIUVO, 45 in the mitotane and 46 in the observation arm. Baseline characteristics of patients were perfectly matched between the 2 arms: median age, 51 vs. 50.5 years; female, 73% vs. 67%; stage I, 20% vs. 26%; stage II, 67% vs. 63%, stage III, 13% vs. 11%; ACC secretion 44% vs. 36%; Weiss 5 vs. 5; respectively. In ADIUVO OBSERVATIONAL, 42 patients were treated with mitotane and 53 were untreated. Baseline characteristics of patients were matched between the 2 groups and with mitotane and observation groups in ADIUVO. Thus, the ADIUVO OBSERVATIONAL cohort was analyzed in parallel to deal with the lower than expected recruitment in ADIUVO. Results: In the ADIUVO study, recurrences were 8 in the MIT and 11 in the OBS arm, while deaths were 2 and 5, respectively. RFS and overall survival (OS) did not significantly differ between the 2 arms. In the OBS arm, the HR for recurrence was 1.321 (95%CI, 0.55-3.32, p = 0.54) and HR for death 2.171 (95%CI, 0.52-12.12, p = 0.29). The survival analysis in the ADIUVO OBSERVATIONAL study confirmed that of ADIUVO. Given the outcome of both studies, the NNT is 55. Conclusions: ACC patients at low-intermediate risk of recurrence after surgery are a minority; however, they show a far better prognosis than expected (5-yr RFS is 75%) and do not benefit significantly from adjuvant mitotane. The results of the ADIUVO study do not support routine use of adjuvant mitotane in this subset of patients, who may thus avoid a potentially toxic treatment. This is an important step toward personalization of ACC care. Clinical trial information: NCT00777244.

Abstract
BACKGROUND If biochemical control of acromegaly is not achieved by operation and medication, radiotherapy may be indicated. OBJECTIVE To describe fractionated radiotherapy (FRT) and stereotactic radiosurgery (SRS) regarding excess of IGF-1 and pituitary function. DESIGN AND METHODS A retrospective analysis of 352 patients (4126 patient-years) from the German Acromegaly Registry was performed. Follow-up was 1.0-45.1 years after radiotherapy. Therapeutic success was defined by low or normal IGF-1 according to center-specific reference ranges without (= remission) or on (= controlled disease) suppressive medication. RESULTS Time between radiotherapy and last follow-up was 13.0 ± 8.2 years for FRT (n = 233) and 8.9 ± 5.0 years for SRS (n = 119, P < 0.001). Median (IQR) basal growth hormone before radiotherapy was 6.3 (2.9-16.2) ng/mL for FRT and 3.5 (1.8-6.9) ng/mL for SRS (P < 0.001). Mean time in uncontrolled state was 3.0 years after FRT and 2.1 years after SRS (95% CI for the difference is 0.1 to 1.6 years, P = 0.021). The 10-year calculated remission rate was 48% for FRT and 52% for SRS (95% CI for the difference is -18 to 26% age points, P = 0.74) and the respective controlled disease rate was 23 and 26%. The odds ratio for adrenocorticotropic or thyreotropic insufficiency was 0.54 (95% CI: 0.30-1.00, P = 0.049) in SRS compared to FRT patients. CONCLUSION Both after FRT and SRS about 75% of patients with acromegaly are in remission or controlled after 10 years. A slightly faster achievement of target values was observed after SRS. The rate of pituitary insufficiency in FRT patients is significantly higher.

Abstract
Adrenocortical carcinomas (ACC) are rare but highly aggressive tumors. It is very difficult to differentiate small locally limited ACCs from benign adenomas. A spontaneous density >10 Hounsfield units in non-enhanced CT scan and a slow washout after contrast injection are suspicious of malignancy but with a low specificity. Preoperatively, a hormonal work-up is mandatory for all adrenal tumors. Each patient should be discussed in an interdisciplinary board. For non-metastatic ACCs (ENSAT stages I-III) radical resection is the treatment of choice. R0-resection and avoiding violation of the tumor capsule are the most important prognostic factors for long-term survival. Although discrepant reports regarding the benefits of lymphadenectomy have been published, lymph node dissection at least in the periadrenal area and in the renal hilum (optional extension to paraaortal and paracaval nodes) should be performed in the case of lymph node involvement. The role of prophylactic lymphadenectomy needs to be analyzed in further studies. The gold standard remains the open approach but minimally invasive procedures are also an option, especially in stage I-II tumors, if the principles of oncological surgery are respected. In this case, long-term survival rates are comparable. As local recurrence rates are lower and time to local recurrence is longer in patients who are operated on at a dedicated center (>10 adrenalectomies/year), adrenalectomy for ACC should be performed by an experienced surgeon.

Abstract
BACKGROUND AND AIMS Previous guidelines addressing surgery of adrenal tumors required actualization in adaption of developments in the area. The present guideline aims to provide practical and qualified recommendations on an evidence-based level reviewing the prevalent literature for the surgical therapy of adrenal tumors referring to patients of all age groups in operative medicine who require adrenal surgery. It primarily addresses general and visceral surgeons but offers information for all medical doctors related to conservative, ambulatory or inpatient care, rehabilitation, and general practice as well as pediatrics. It extends to interested patients to improve the knowledge and participation in the decision-making process regarding indications and methods of management of adrenal tumors. Furthermore, it provides effective medical options for the surgical treatment of adrenal lesions and balances positive and negative effects. Specific clinical questions addressed refer to indication, diagnostic procedures, effective therapeutic alternatives to surgery, type and extent of surgery, and postoperative management and follow-up regime. METHODS A PubMed research using specific key words identified literature to be considered and was evaluated for evidence previous to a formal Delphi decision process that finalized consented recommendations in a multidisciplinary setting. RESULTS Overall, 12 general and 52 specific recommendations regarding surgery for adrenal tumors were generated and complementary comments provided. CONCLUSION Effective and balanced medical options for the surgical treatment of adrenal tumors are provided on evidence-base. Specific clinical questions regarding indication, diagnostic procedures, alternatives to and type as well as extent of surgery for adrenal tumors including postoperative management are addressed.

Abstract
OBJECTIVE Adrenal vein sampling (AVS) represents the current diagnostic standard for subtype differentiation in primary aldosteronism (PA). However, AVS has its drawbacks. It is invasive, expensive, requires an experienced interventional radiologist and comes with radiation exposure. However, exact radiation exposure of patients undergoing AVS has never been examined. DESIGN AND METHODS We retrospectively analyzed radiation exposure of 656 AVS performed between 1999 and 2017 at four university hospitals. The primary outcomes were dose area product (DAP) and fluoroscopy time (FT). Consecutively the effective dose (ED) was approximately calculated. RESULTS Median DAP was found to be 32.5 Gy*cm2 (0.3–3181) and FT 18 min (0.3–184). The calculated ED was 6.4 mSv (0.1–636). Remarkably, values between participating centers highly varied: Median DAP ranged from 16 to 147 Gy*cm2, FT from 16 to 27 min, and ED from 3.2 to 29 mSv. As main reason for this variation, differences regarding AVS protocols between centers could be identified, such as number of sampling locations, frames per second and the use of digital subtraction angiographies. CONCLUSIONS This first systematic assessment of radiation exposure in AVS not only shows fairly high values for patients, but also states notable differences among the centers. Thus, we not only recommend taking into account the risk of radiation exposure, when referring patients to undergo AVS, but also to establish improved standard operating procedures to prevent unnecessary radiation exposure.

Abstract
PURPOSE Chronic inflammation is an age-independent and body mass index-independent contributor to the development of multi-morbidity. Alterations of the renin-angiotensin-aldosterone system are observed within the context of proinflammatory states. We assessed circulating aldosterone, renin, and inflammatory biomarker concentrations in healthy, normotensive subjects and patients with primary aldosteronism. METHODS We included 1177 normotensive individuals from the population-based Study of Health in Pomerania (first follow-up, Study of Health in Pomerania-1) and 103 primary aldosteronism patients from the German Conn's Registry. A 1:1 matching for sex, age, body mass index, smoking status, diabetes mellitus, and the estimated glomerular filtration rate was performed to determine whether primary aldosteronism patients exhibit higher inflammatory biomarker concentrations than normotensive controls. The associations of plasma aldosterone concentration or plasma renin concentration with circulating fibrinogen concentrations, white blood cell count, and high sensitive C-reactive protein concentrations in the normotensive sample were determined with multivariable linear and logistic regression analyses. RESULTS 1:1 matched primary aldosteronism patients demonstrated significantly (p < 0.01) higher plasma aldosterone concentration (198 vs. 47 ng/l), lower plasma renin concentration (3.1 vs. 7.7 ng/l) and higher high sensitive C-reactive protein concentrations (1.5 vs. 1.0 mg/l) than normotensive controls. Within the normotensive cohort, plasma renin concentration but not plasma aldosterone concentration was positively associated with fibrinogen concentrations and white blood cell count. Further, a J-shaped association between plasma renin concentration and high sensitive C-reactive protein concentrations was detected. CONCLUSIONS High plasma aldosterone concentration in a primary aldosteronism cohort and high plasma renin concentration in normotensive subjects are associated with increased concentrations of inflammatory biomarkers. This suggests a link between the renin-angiotensin-aldosterone system and inflammatory processes in patients with primary aldosteronism and even in normotensive subjects.

Abstract
Primary aldosteronism (PA), the most common form of secondary hypertension, causes relevant morbidity. The value of salivary measurements of aldosterone in clinical routine in PA so far has not been assessed. First, we analyzed salivary and plasma aldosterone concentrations of 42 patients with PA and 37 hypertensive controls (HC) during a sodium infusion test prospectively. Second, morning salivary and plasma aldosterone concentrations as well as diurnal saliva aldosterone profiles were analyzed in 115 patients treated for PA (46 adrenalectomy, 56 spironolactone, 13 eplerenone). Salivary aldosterone was substantially elevated in PA patients compared to HC at baseline (106±119 vs. 40±21 ng/l, p=0.01), and after 4-h sodium infusion test (60±36 vs. 23±14, p=0.01). Positive correlation between salivary and plasma aldosterone levels was evident, with exception of concentrations in or below the lower normal range. Applying a salivary aldosterone cutoff of 51.2 ng/l, found by ROC curve analysis, rendered a sensitivity of 81% and a specificity of 73% for PA. The diurnal rhythm of aldosterone was preserved in untreated PA patients, but concentrations were higher in the context of PA, and normalized after surgery (118±57 vs. 31±18 ng/l, p<0.01). Taken together, salivary aldosterone measurements correlate with plasma levels, allowing simple and cost effective assessments of aldosterone secretion in an outpatient setting. Nevertheless, as this method alone cannot replace other plasma parameters, and as aldosterone profiling would not alter diagnostic or treatment strategies, salivary aldosterone measurements in routine practice are of limited clinical value.

Abstract
BACKGROUND The clinical course of advanced adrenocortical carcinoma (ACC) is heterogeneous. Our study aimed primarily to refine and make headway in the prognostic stratification of advanced ACC. PATIENTS AND METHODS Patients with advanced ENSAT ACC (stage III or stage IV) at diagnosis registered between 2000 and 2009 in the ENSAT database were enrolled. The primary end point was overall survival (OS). Parameters of potential prognostic relevance were selected. Univariate and multivariate analyses were carried out: model 1 'before surgery'; model 2 'post-surgery'. RESULTS Four hundred and forty-four patients with advanced ENSAT ACC (stage III: 210; stage IV: 234) were analyzed. After a median follow-up of 55.2 months, the median OS was 24 months. A modified ENSAT (mENSAT) classification was validated: stage III (invasion of surrounding tissues/organs or the vena renalis/cava) and stage IVa, IVb, IVc (2, 3 or >3 metastatic organs, including N, respectively). Two- or 5-year OS was 73%, 46%, 26% and 15% or 50%, 15%, 14% and 2% for stages III, IVa, IVb and IVc, respectively. In the multivariate analysis, mENSAT stages (stages IVa, IVb, or IVc, respectively) were significantly correlated with OS (P < 0.0001), as well as additional parameters: age ≥ 50 years (P < 0.0001), tumor- or hormone-related symptoms (P = 0.01 and 0.03, respectively) in model 1 but also the R status (P = 0.001) and Grade (Weiss >6 and/or Ki67 ≥ 20%, P = 0.06) in model 2. CONCLUSION The mENSAT classification and GRAS parameters (Grade, R status, Age and Symptoms) were found to best stratify the prognosis of patients with advanced ACC.

Abstract
Autoimmune adrenalitis (AA) and congenital adrenal hyperplasia (CAH) are the most common reasons for acquired and monogenetic primary adrenal insufficiency. Both concern women in their fertile years. The aim of the work was to examine fertility rates, pregnancy outcome, and children's characteristics in AA and CAH patients in 2 German endocrine centers. One hundred and fifty-eight women were contacted. Thirty-nine patients with CAH due to 21-hydroxlase deficiency and 54 AA patients agreed and were included. Information about course and outcome of pregnancies was obtained by questionnaire and telephone interview. Fertility rates were calculated and compared to expected values from the German general population. Twelve CAH patients (30.8%) had 25 pregnancies, which resulted in 16 children. In AA patients, 93 pregnancies in 42 women (75%) were reported resulting in 73 childbirths. Fertility rates were normal in nonclassic CAH and in AA-only patients, but significantly reduced in classic CAH and autoimmune polyendocrine syndrome type 2 (APS-2). Rates of miscarriages were high in all CAH (36%) and APS-2 (22%) patients. The majority of children in both groups were born at term, but rates of cesarean section were elevated in classic CAH and in AA patients<5 years before or after diagnosis. Children born to CAH patients weighed significantly less than expected and 33.3% of them were born small for gestational age. Fertility seems not to be reduced in general, but specific in classic CAH and APS 2 patients. Nevertheless all CAH and AA patients seem to be at risk of miscarriages and cesarean section.

Abstract
CONTEXT Primary aldosteronism (PA) is the most common cause of secondary hypertension. Aldosterone excess can cause DNA damage in vitro and in vivo. Single case reports have indicated a coincidence of PA with renal cell carcinoma and other tumors. However, the prevalence of benign and malignant neoplasms in patients with PA has not yet been studied. PATIENTS AND DESIGN In the multicenter MEPHISTO study, the prevalence of benign and malignant tumors was investigated in 335 patients with confirmed PA. Matched hypertensive subjects from the population-based Study of Health in Pomerania cohort served as controls. RESULTS Of the 335 PA patients, 119 (35.5%) had been diagnosed with a tumor at any time, and 30 had two or more neoplasms. Lifetime malignancy occurrence was reported in 9.6% of PA patients compared to 6.0% of hypertensive controls (P = .08). PA patients with a history of malignancy had higher baseline aldosterone levels at diagnosis of PA (P = .009), and a strong association between aldosterone levels and the prevalence of malignancies was observed (P = .03). In total, 157 neoplasms were identified in the PA patients; they were benign in 61% and malignant in 25% of the cases (14% of unknown dignity). Renal cell carcinoma was diagnosed in five patients (13% of all malignancies) and was not reported in controls CONCLUSION Compared to hypertensive controls, the prevalence of malignancies was positively correlated with aldosterone levels, tended to be higher in PA patients, but did not differ significantly.

Abstract
In recent years, an increasing number of studies have revealed deleterious effects of aldosterone via the mineralocorticoid receptor (MR). Especially in patients with primary aldosteronism (PA) a significant higher estimated risk of developing cardiovascular comorbidities and comortalities compared to essential hypertensives was reported. As diabetes mellitus and the metabolic syndrome are one of the major contributors to cardiovascular morbidity and mortality their connection to aldosterone excess became a focus of research in PA patients. Several studies assessed the effect of PA on glucose metabolism, the prevalence of diabetes mellitus, and the effect of PA treatment on both revealing different results. Therefore, we performed an extensive literature research. This review focuses on the current knowledge of the connection between aldosterone excess, glucose homeostasis, and diabetes mellitus in patients with PA. We have highlighted this topic from a pro and contra perspective followed by a summarizing concluding remark. Additionally, we have briefly reviewed the data on possible underlying mechanisms and indicated future considerations on the possible impact of cortisol co-secretion in PA.

Abstract
The only approved drug for the treatment of adrenocortical cancer (ACC) is mitotane. Mitotane is adrenolytic and therefore, hydrocortisone replacement therapy is necessary. Since mitotane increases cortisol binding globulin (CBG) and induces CYP3A4 activity, high doses of hydrocortisone are thought to be required. Evaluation of hydrocortisone therapy in mitotane-treated patients has been difficult since there is no good marker to evaluate hydrocortisone therapy. Measurement of cortisol in scalp hair is a novel method that offers the opportunity to measure long-term cortisol levels. Our aim was to evaluate whether hair cortisol measurements could be useful in evaluating recent hydrocortisone treatment in mitotane-treated ACC patients. Hair cortisol levels were measured in 15 mitotane-treated ACC patients on hydrocortisone substitution and 96 healthy individuals. Cortisol levels were measured in 3 cm hair segments, corresponding to a period of 3 months. Hair cortisol levels were higher in ACC patients compared to healthy individuals (p<0.0001). Seven ACC patients (47%) had hair cortisol levels above the reference range. None of the patients had hair cortisol levels below normal. In contrast to hydrocortisone doses (β=0.03, p=0.93), hair cortisol levels were associated with BMI (β=0.53, p=0.042). There was no correlation between hair cortisol levels and hydrocortisone doses (β=0.41, p=0.13). Almost half of the ACC patients had high hair cortisol levels, suggesting long-term over-substitution of hydrocortisone in some of the patients, whereas none of the patients was under-substituted. Hair cortisol measurements might be useful in long-term monitoring hydrocortisone treatment in mitotane-treated ACC patients.

Abstract
Primary aldosteronism (PA) is the most frequent cause of secondary arterial hypertension. The aldosterone to renin ratio (ARR) is the gold standard for screening, but variability between biochemical methods used remains of concern. The aim of the study was to analyze center-specific features of biochemical diagnostic strategies prior to the 2008 consensus within the German Conn's Registry. The study was designed as a retrospective study in 5 tertiary care hospitals. Patients analyzed for PA between 1990 and 2006 were studied. Characteristics of the assays used to determine ARR during establishing the diagnosis of PA were analyzed in the retrospective part of the German Conn's Registry. Eighty-six out of 484 documented ARR values had to be excluded from further evaluations because the laboratory or the assays were unknown. In the remaining 398 patients ARR was determined using 10 different assay combinations in the centers (aldosterone plus plasma renin activity or concentration). Considerable differences were seen between the mean concentrations for aldosterone (p<0.0001), renin concentration (p<0.001), and renin activity (p=0.009) for the different assays. The differences between the absolute concentrations measured by the different assays also had significant impact upon the resulting mean ratios. If published cutoff values are applied, the use of different commercial assays to determine the ARR in clinical routine results in major differences in positive screening rates. This heterogeneity affects sensitivity and specificity of screening for PA. Our data emphasize the importance of standardized screening procedures, which must include standardization of biochemical methods.

Abstract
Patients with adrenal insufficiency (AI) receive first glucocorticoid replacement dose after waking, resulting in a 3-5 h delay compared to physiological secretion. Impaired quality of life (QoL) and fatigue might be due to this delayed dose scheme. Modified-release glucocorticoid preparations might have therapeutic advantages. Exploratory pilot study including 14 patients with AI was conducted in a single university center. Patients on morning dose prednisolone (5 mg) were included, switched to modified-release prednisone (5 mg) at 10 PM for 3 months, and then switched back on standard prednisolone. 3 standardized questionnaires (GBB-24, MFI, and AddiQoL) investigating complaints and fatigue were completed at baseline, after 3, and 6 months. Data regarding clinical and hormonal parameters were assessed. Modified-release prednisone showed significant improvement in one of 4 scales of GBB-24 and positive trends to better scores in 3 of 4 scales. The global score of discomfort improved significantly. The MFI showed also significant improvement in 3 of 5 scales and positive trend to better scores in 2 scales. Significant changes to better scores were seen in 4 out of 30 items of the AddiQoL. Modified-release prednisone showed decreased complaints and fatigue compared to standard prednisolone indicating importance of glucocorticoid increase in early morning hours before waking.

Abstract
The clinical signs and symptoms of primary adrenal insufficiency are unspecific often causing a delayed diagnosis or even misdiagnosis. In the diagnostic work-up the short synacthen test is regarded as the gold standard. Hydrocortisone and fludrocortisone are the preferred therapy for Addison's disease. The management and surveillance of therapy requires experience and several aspects need to be followed to prevent side effects which might occur due to overtreatment or undertreatment. Very important aspects in therapy are the repeated teaching of the patient and relatives, the issuing of an emergency steroid card and the prescription of a glucocorticoid emergency set. Acute adrenal failure (adrenal crisis), which might be the first manifestation of adrenal insufficiency, is a life-threatening situation requiring immediate glucocorticoid administration and fluid substitution. The most common causes for an adrenal crisis are gastrointestinal infections and fever and discontinuation of glucocorticoid therapy. This article gives an up-to-date overview of diagnostic and therapeutic aspects of Addison's disease.

Abstract
BACKGROUND Sex-specific differences in blood pressure (BP) suggest an important modulating role of testosterone in the kidney. However, little is known about the interaction between androgens and the mineralocorticoid aldosterone. Our objective was to determine the effects of testosterone in gonadectomized male and female rats on a low-salt diet, and to determine the effect of androgen receptor (AR) blockade by flutamide on BP and on aldosterone levels. METHODS Normotensive male and female Wistar rats were gonadectomized and put on a low-salt diet. They were treated for 16 days with testosterone or placebo. In addition, the animals received the AR antagonist flutamide or placebo, respectively. BP was measured by tail-cuff method, 24-h urine samples were collected in metabolic cages and blood was collected for hormonal measurements. RESULTS Testosterone increased BP in males and females, and this effect could be blocked by flutamide. Flutamide treatment itself significantly increased aldosterone levels in male but not in female rats. These elevated aldosterone levels could be lowered by testosterone treatment during AR blockade. Accordingly to aldosterone levels, flutamide increased in males the serum sodium/potassium to urinary sodium/potassium ratio, an in vivo indicator of renal aldosterone action. CONCLUSIONS Testosterone regulates BP in male and female gonadectomized rats via the AR. Flutamide by itself exerts influence over aldosterone in the absence of gonadal steroid replacement suggesting AR involvement in renal sodium handling. These flutamide effects were sex-specific and not seen in female rats.

Abstract
A low-salt diet is known to decrease and salt excess to increase blood pressure in humans and rodents. Sex steroids seem to play a role in salt dependent hypertension. However, little is known about sex differences in mineralocorticoid receptor blockade between male and female rats. The objective of the work was at first to investigate the effects of a low-salt vs. a high-salt diet on blood pressure without the influence of gonadal steroids in male and female rats. Second, to determine the sex-specific effects of mineralocorticoid receptor blockade by spironolactone in high-salt and low-salt fed gonadectomized male and female animals. Normotensive male and female Wistar rats were gonadectomized and put on a low (NaCl<0.03%) or high (NaCl=4%) salt diet. On each diet animals received spironolactone or placebo. Blood pressure was measured by tail-cuff-method; 24-h urine samples were collected in metabolic cages and blood was collected for hormonal measurements. High-salt diet significantly increased systolic blood pressure in both sexes. This effect could be blocked effectively by spironolactone only in male rats. Spironolactone treatment significantly increased aldosterone levels in males and females independent of the sodium content of the diet. High sodium diet significantly increased relative kidney weight, which was not altered by spironolactone treatment. Independently of gonadal steroids a high-salt diet increased blood pressure in gonadectomized male and female rats. Spironolactone lowered blood pressure only in male not in female rats on a high-salt diet clearly indicating sex-specific effects of the mineralo-corticoid antagonist spironolactone.

Abstract
The mineralocorticoid aldosterone is a key regulator of blood pressure, fluid and electrolyte homeostasis, and acts via the mineralocorticoid receptor (MR). In recent years, an increasing number of studies revealed deleterious effects of aldosterone via its receptor. Especially in patients with primary hyperaldosteronism (PHA) a significant higher risk of developing cardiovascular comorbidities and comortalities was reported. Also renal insufficiency is clearly increased in patients with PHA indicating a role of aldosterone and the MR in the pathogenesis of renal injury. It has been shown that aldosterone in combination with an elevated salt intake, leads to renal inflammation, fibrosis, podocyte injury, and mesangial cell proliferation. This review focuses on the current knowledge of aldosterone effects in the kidney and highlights this topic from 2 perspectives: from clinical medicine and from experimental studies.

Abstract
CONTEXT Patients with primary adrenal insufficiency (PAI) and patients with congenital adrenal hyperplasia (CAH) receive glucocorticoid replacement therapy, which might cause osteoporosis. OBJECTIVES Questions addressed by this study were: 1) Is bone mineral density (BMD) reduced in PAI and CAH on lower glucocorticoid doses than previously reported? 2) Is BMD in PAI influenced by the type of glucocorticoid used? and 3) Does DHEA treatment affect BMD in PAI women? DESIGN AND PATIENTS We conducted a prospective, cross-sectional study including 81 PAI patients and 41 CAH patients. MAIN OUTCOME MEASURES BMD was measured by dual-energy x-ray absorptiometry. Serum levels of bone turnover markers, minerals, vitamins, hormones, and urinary crosslinks were measured. RESULTS PAI and CAH patients received average daily hydrocortisone doses of 12.0 ± 2.7 mg/m(2) (range, 4.9-19.1) and 15.5 ± 7.8 mg/m(2) (range, 5.7-33.7), respectively. BMD varied within the normal reference range (-2 to +2) in both cohorts. However, lower Z-scores for femoral neck and Ward's region were found in CAH compared to PAI women, but not in men. Prednisolone treatment showed significant lower osteocalcin levels and lower Z-scores for lumbar spine and femoral neck compared to PAI patients on hydrocortisone. PAI women treated with DHEA had significantly lower urinary collagen crosslinks and bone alkaline phosphatase, and significantly higher Z-scores in lumbar spine and femoral Ward's region compared to non-DHEA-treated women. CONCLUSIONS Adult PAI and CAH patients on low glucocorticoid doses showed normal BMD within the normal reference range. The use of longer acting prednisolone resulted in significantly lower BMD in PAI. In addition, DHEA treatment may have a beneficial effect on bone in Addison's women.

Abstract
The 11β-hydroxysteroid dehydrogenases (11β-HSDs) play a pivotal role in glucocorticoid (GC) action. 11β-HSD1 is a predominant reductase, activating GCs from inert metabolites, whereas 11β-HSD2 is a potent dehydrogenase inactivating GCs. Knowing the metabolic effects of GCs, a selective inhibition of 11β-HSD1 represents a potential target for therapy of impaired glucose tolerance, insulin insensitivity and central obesity. In vitro, 11β-HSD1 is selectively inhibited by chenodesoxycholic acid (CDCA) and upregulated under GC exposure. Therefore, we aimed to investigate the effects of CDCA and prednisolone on hepatic 11β-HSD1 activity in vivo by measuring 11-reduction of orally given cortisone (E) acetate to cortisol (F). CDCA or placebo was given to 5 male healthy volunteers within a randomised cross-over trial before and after oral administration of 12.5 mg E acetate at 8:00 h. For measurement of in vivo effects of GCs on 11β-HSD1 activity, hepatic reduction of 25 mg E acetate before and after treatment with prednisolone (30 mg for 6 days) was determined in 7 healthy males. Serum GC levels were determined using a fully automated liquid chromatographic system. CDCA had no effect on the activity of 11β-HSD1 in vivo. Prednisolone therapy leads to a marked rise in serum F concentrations and an elevated F/E serum ratio. This proves GC-induced activation of hepatic 11β-HSD1, which could not be extinguished by a parallel increase of IGF-1 under prednisolone. CDCA does not affect in vivo activity of 11β-HSD1 when given in therapeutic dosages. During GC treatment, increased hepatic activation of E to F may aggravate metabolic side effects of GCs such as seen in the metabolic syndrome.

Abstract
Primary hyperparathyroidism is a common endocrine disease. Since introduction of automated routine measurement of serum calcium the detection of primary hyperparathyroidism has increased significantly. The classical symptoms such as kidney stones, gastrointestinal and bone manifestation are rarely seen nowadays. For this reason, an elevated parathyroid hormone level in a patient with hypercalcemia confirms primary hyperparathyroidism in 95 % of cases. Currently 80 % of these patients are asymptomatic, and therefore criteria for diagnosis and treatment have been discussed on several consensus conferences. After biochemical confirmation has been obtained further diagnostic test aim at locating the tumor should be by ultrasound and 99m TC-sestamibi scintigraphy. The improved diagnostic work-up had led to a better surgical approach with minimally invasive and endoscopic techniques. In addition, quick intraoperative parathyroid hormone measurements confirm immediately the success of surgical treatment. Non-surgical treatment in asymptomatic and elderly patients may be justified. Bisphosphonates are the first choice for medical treatment in patients with bone manifestation and cinacalcet may be given to patients to lower calcium and parathyroid hormone levels.

Abstract
Patients presenting with primary aldosteronism experience more cardiovascular events than patients with essential hypertension independent of blood pressure. Therefore, the presence of primary aldosteronism should be detected, not only to determine the cause of hypertension, but also to prevent such complications. This review focuses on human data regarding increased end-organ damage and comorbidities in primary aldosteronism. Special emphasis is put on the effects of aldosterone excess on blood vessels, the heart, the kidney, and the brain. The data reviewed in our article demonstrate that primary aldosteronism is associated with a prevalence of cerebro-, cardiovascular and renal complications that are out of proportion to the blood pressure and benefits substantially from treatment in the long term. In this view, adrenalectomy and aldosterone antagonist treatment seem to be of considerable therapeutic value to control and limit the progression of comorbidities in primary aldosteronism.

Abstract
Aldosterone excess in the context of primary aldosteronism (PA) has been associated with impaired glucose tolerance and diabetes mellitus. We retrospectively assessed the prevalence of diabetes mellitus in patients from the German Conn's Register and compared the data with those from hypertensive subjects of a population-based survey. In a case-control study, we have compared 638 patients with PA from the German Conn's registry who were treated in 6 German centers with 897 hypertensive control subjects from the population-based F3 survey of the Cooperative Health Research in the Region of Augsburg (KORA). The samples were matched for age, sex, and blood pressure in a 1:1 ratio. Risk factors associated with the presence of diabetes mellitus were calculated in 638 patients with PA and 897 hypertensive controls. In the case control study, the diabetes prevalence was calculated in 338 cases and controls. In patients with primary aldosteronism, age, BMI, and a higher number of antihypertensive drugs (lowest tertile vs. highest tertile) were variables associated with diabetes mellitus. In contrast, serum potassium and plasma aldosterone concentrations were not associated with higher diabetes prevalence, whereas diastolic blood pressure was inversely associated with diabetes mellitus. Diabetes mellitus was more prevalent in patients with PA than in 338 matched controls (23 vs. 10% in controls). Our data for the German population show that diabetes mellitus is more prevalent in patients with primary aldosteronism than in hypertensive controls.

Abstract
Adrenal insufficiency is caused by either primary adrenal failure, mostly due to autoimmune adrenalitis, or by hypothalamic-pituitary impairment of the corticotropic axis, predominantly by long-term pharmacodynamic glucocorticoid treatment or by pituitary tumour growth and related treatment. Despite optimized life-saving glucocorticoid and mineralocorticoid replacement therapy, health-related quality of life in adrenal insufficiency is more severely impaired than previously thought and patients with adrenal insufficiency are also threatened by an increased mortality. Optimizing hormone replacement remains one of the most challenging tasks in endocrinology. Monitoring of glucocorticoid replacement quality is hampered by lack of objective assessment tools and therefore largely based on clinical grounds. Thus, long-term management of patients with adrenal insufficiency remains a continuous challenge asking for the experienced specialist. However, diagnosis and management of suspected acute adrenal failure is an important task for all physicians. This review explains the rationale behind the current hormone replacement scheme, points to the deficits and hints at possible future therapies.

Abstract
Primary aldosteronism (PA) is associated with vascular end organ damage. The aim of the study was to evaluate differences regarding comorbidities depending on tumor size in patients with aldosterone producing adenoma (APA). The retrospective cross-sectional study was done by collection from 6 German centers (German Conn's registry) between 1990 and 2007. Among the 640 registered patients with PA, 60 operated patients with APA were analyzed. The main outcome of measures was the comorbidities depending on tumor size. Thirty-one patients (17 men, 14 women) had an adenoma size <20 mm, and 29 patients (10 men, 19 women) had an adenoma size>/=20 mm. There was no difference in age, preoperative potassium, aldosterone, or creatinine levels, preoperative systolic and diastolic blood pressure, or duration of hypertension between the two groups. In the group with APA <20 mm, cerebrovascular events occurred with a prevalence of 12.9%, cardiac events 16.1%, peripheral vascular events 25.8%, renal insufficiency 16.1%, and sleep apnea 6.4%, respectively. There was no significant difference in comorbidities compared to the group with APA>/=20 mm. Subgroup analysis (n=22) of follow-up data on post-operative systolic and diastolic blood pressure showed no significant difference between these subgroups with regard to potassium, aldosterone or creatinine levels, blood pressure, duration of hypertension, or comorbidities. Our data indicate a high prevalence of comorbidities in patients with APA. However, adenoma size was not correlated with cardio- and cerebrovascular comorbidities, and does not seem to be a prognostic factor for blood pressure outcome.

Abstract
With the beginning of puberty blood pressure increases and is persistently higher in men than in premenopausal women. Sex steroids are known to have complex effects on the renal and cardiovascular system and are involved in blood pressure regulation. The epithelial sodium channel (ENaC) modulates sodium reabsorption in the kidney, but little is known about sex-specific regulation of ENaC subunit expression. Regulation of the androgen receptor (AR) is known to be tissue-specific and age-dependent, but not well studied in the kidney. We investigated the effects of sex steroids on ENaC subunits and renal AR expression in an in vivo rat model. Ovariectomized female Wistar rats were treated with placebo, testosterone, 5 alpha-dihydrotestosterone (DHT) or 17 beta-estradiol (E2) for 14 days, and quantitative PCR and Western immunoblots were performed. DHT significantly decreased expression of all ENaC subunits in female rats, whereas testosterone showed only a trend to lower ENaC expression. These results are in contrast to previous studies where stimulating effects of androgens on the alpha-subunit of ENaC were seen. AR mRNA expression showed a trend to lower levels in females after testosterone treatment in this study. However, estrogen treatment significantly downregulated AR mRNA expression. In male control animals we were able to show a significantly increased expression of AR mRNA upon testosterone treatment. Our data demonstrate that AR and ENaC are regulated by sex steroids. That way sex steroids might modulate renal sodium reabsorption and therefore provide a possible explanation for sex differences in blood pressure.

Abstract
CONTEXT Primary aldosteronism (PA) is associated with vascular end-organ damage. OBJECTIVE Our objective was to evaluate differences regarding comorbidities between the hypokalemic and normokalemic form of PA. DESIGN AND SETTING This was a retrospective cross-sectional study collected from six German centers (German Conn's registry) between 1990 and 2007. PATIENTS Of 640 registered patients with PA, 553 patients were analyzed. MAIN OUTCOME MEASURES Comorbidities depending on hypokalemia or normokalemia were examined. RESULTS Of the 553 patients (61 +/- 13 yr, range 13-96), 56.1% had hypokalemic PA. The systolic (164 +/- 29 vs. 155 +/- 27 mm Hg; P < 0.01) and diastolic (96 +/- 18 vs. 93 +/- 15 mm Hg; P < 0.05) blood pressures were significantly higher in hypokalemic patients than in those with the normokalemic variant. The prevalence of cardiovascular events (angina pectoris, myocardial infarction, chronic cardiac insufficiency, coronary angioplasty) was 16.3%. Atrial fibrillation occurred in 7.1% and other atrial or ventricular arrhythmia in 5.2% of the patients. Angina pectoris and chronic cardiac insufficiency were significantly more prevalent in hypokalemic PA (9.0 vs. 2.1%, P < 0.001; 5.5 vs. 2.1%, P < 0.01). Overall, cerebrovascular comorbidities were not different between hypokalemic and normokalemic patients, however, stroke tended to be more prevalent in normokalemic patients. CONCLUSIONS Our data indicate a high prevalence of comorbidities in patients with PA. The hypokalemic variant is defined by a higher morbidity than the normokalemic variant regarding some cardiovascular but not cerebrovascular events. Thus, PA should be sought not only in hypokalemic but also in normokalemic hypertensives because high-excess morbidity occurs in both subgroups.

Abstract
BACKGROUND The aldosterone-to-renin ratio (ARR) is an established diagnostic tool in the screening for primary aldosteronism (PA). However, hormonal determinations are time consuming and expensive. Therefore, we studied the effectiveness of the serum sodium to urinary sodium to (serum potassium)(2) to urinary potassium (SUSPPUP) ratio in the diagnosis of PA. DESIGN This study included 35 patients with PA, 71 patients with essential hypertension to whom this diagnosis could be excluded, 23 normal subjects without hypertension, and 22 patients with primary adrenal insufficiency. We compared the SUSPPUP ratios with the ARR in these patient groups. RESULTS We show that the ARR distinguished PA from essential hypertension with a sensitivity of 94.2% and a specificity of 92.1% at a cutoff of 33 (ng L(-1): ng L(-1)). It correlated well with the SUSPPUP ratio. The sensitivity and specificity of SUSPPUP was 88.6% and 85.9% at a cutoff of 5.3 (mmol L(-1))(-1), respectively, and thus not as good as the ARR. CONCLUSIONS The ARR is a good parameter in the screening for PA. The SUSPPUP ratio is a cheap and rapid tool to assess the extent of mineralocorticoid excess and, therefore, can be offered to more patients. In addition, the application of the SUSPPUP ratio can be extended to patients who suffer from other forms of mineralocorticoid hypertension (e.g. with low aldosterone levels).

Abstract
AIM Radiofrequency thermal ablation (RFA) has shown promise as a technique for treating solid tumors. This method has been suggested as an alternative to surgery in patients with adrenocortical carcinoma (ACC). MATERIALS AND METHODS We reviewed the literature, and report the case of a patient with stage 4 ACC who received intraoperative and percutaneous RFA of two liver metastasis according to a standard ablation protocol. RESULTS Post-interventional imaging in our patient demonstrated that after both interventions, a stellar-like structure of vital tumor tissue had remained within the coagulation necrosis. This was the starting point of a fast and progressive tumor recurrence. We suspect heat-sink effects of blood vessels in the highly vascularized metastasis to cause the tumor recurrence. In literature, there are only a few reports of RFA in ACC patients. In addition, there is no large randomized trial investigating the efficacy of RFA against surgery in those patients. CONCLUSIONS Presently, RFA in ACC should be restricted to patients in whom surgery is contraindicated. It is necessary that strongly vascularized ACC metastases deserve a modified ablation protocol due to perfusion related cooling effects and to increase the efficacy of RFA.
