Lower health-related quality of life observed in patients with Addison’s disease, Cushing’s syndrome

Patients with hypothalamic-pituitary-adrenal axis dysregulations report health-related quality of life that is far lower than that of the general population, according to findings of a prospective study.

“In most centers, both patients with adrenal deficiency and patients with Cushing’s syndrome are managed by the same team,” Charlotte De Bucy, of the Center for Rare Adrenal Diseases at Cochin Hospital in Paris, and colleagues wrote. “Despite the usual perception that both types of diseases alter quality of life, few studies have similarly investigated the impact of cortisol dysregulations on [health-related quality of life]. Such studies are important, however, to identify meaningful differences that would be important to consider to improve management and outcome.”

De Bucy and colleagues analyzed data from 343 patients with Addison’s disease or Cushing’s syndrome followed in routine practice at a single center in France between September 2007 and April 2014 (78% women; mean age, 48 years; mean length of time since diagnosis, 7.8 years; 61% married). All participants completed the short-form health survey (SF-36), a survey of health-related quality-of-life measures and the 12-item general health questionnaire (GHQ-12), a measure of psychological well-being or distress. Questionnaires were completed at baseline and at 6, 12, 24 and 36 months. Patients with Cushing’s syndrome were also assessed for cortisol status at baseline and at follow-up evaluations.

Within the cohort, 206 had Cushing’s syndrome of pituitary origin, 91 had Cushing’s syndrome of adrenal origin and 46 patients had Addison’s disease; 16% were included in the study before any treatment was initiated.

Researchers found that mean standard deviation scores for psychological and physical dimensions of the SF-36 were “well below” those of the general population, but diagnosis, cortisol status and time since treatment initiation all influenced individual scores. Cushing’s syndrome of pituitary origin was associated with worse health-related quality of life, especially for physical functioning, social functioning and mental health. In Cushing’s syndrome, health-related quality of life was generally worse during periods of hypercortisolism, but scores for these patients were lower than those of patients with Addison’s disease even during periods of hypocortisolism or eucortisolism, according to the researchers.

“The differences were particularly large for physical functioning and role-physical subscales,” the researchers wrote.

They also found that mental health scores for patients with Cushing’s syndrome decreased during periods of hypocortisolism, whereas other adrenal conditions were associated with higher mental health scores.

More than half of patients, regardless of diagnosis and cortisol status, had psychological distress requiring attention, according to the GHQ-12 survey.

“Our findings are important for clinical practice,” the researchers wrote. “The consequences of cortisol dysregulation on [health-related quality of life] should be considered in the management of adrenal insufficiency and even more (in) Cushing’s syndrome patients, and these consequences can be long term, affecting apparently cured patients. Early information on these consequences might be helpful for patients who often perceive a poor quality of life as the result of inadequate disease control or treatment. Even if this possibility exists, knowing that adrenal diseases have long-lasting effects on [health-related quality of life] may be helpful for patients to cope with them.” – by Regina Schaffer

Abstract

Cushing's syndrome (CS) results from prolonged exposure to elevated endogenous cortisol. Majority of cases are caused by ACTH, pituitary, or ectopic origin. Primary adrenal hypersecretion is 15–20% caused by adenomas, carcinomas (ACC), and rarely by nodular adrenocortical disease. CS presents with all typical features.

Commonly recommended initial testing are urinary free cortisol, late-night salivary cortisol, and 1-mg overnight dexamethasone suppression test (DST). Imaging is the key to diagnosis. CS continues to pose diagnostic and therapeutic challenges; life-long follow-up is mandatory.

Abstract:

Objectives  Sustained hypercortisolism impacts cardiac function, and, indeed, cardiac disease is one of the major determinants of mortality in patients with Cushing's syndrome. The aim of this study was to assess the clinical relevance of cardiac structure and function alterations by echocardiography in patients with active Cushing's syndrome and after disease remission.

Study design  Seventy-one patients (61 women, 10 men) with Cushing's syndrome and 70 age-, sex- and blood pressure-matched controls were enrolled. Echocardiography was performed in 49 patients with active disease and at several time points after remission in 44 patients (median follow-up 46·4 months), and prevalence of abnormal left ventricular mass measurements and systolic and diastolic functions indices was compared between patients with active disease, after remission and controls. Twenty-two patients were evaluated both before and after remission.

Results  Up to 70% of patients with active Cushing's syndrome presented abnormal left ventricular mass parameters; 42% presented concentric hypertrophy and 23% concentric remodelling. Major indices of systolic and diastolic functions, i.e. ejection fraction and E/A ratio, respectively, were normal. Upon remission of hypercortisolism, left ventricular mass parameters ameliorated considerably, although abnormal values were still more frequent than in controls. Both cortisol excess and hypertension contribute to cardiac mass alterations and increase the prevalence of target organ damage.

Conclusions  Cushing's syndrome is associated with an increased risk for abnormalities of cardiac mass, which ameliorates, but does not fully disappear after remission. Systolic and diastolic functions are largely within the normal range in these patients.

Synchronous bilateral adrenalectomy by midline incision: A reliable method for treatment of hypercortisolism

Sayyed Abbas Tabatabaee, Sayyed Mozaffar Hashemi, Mohamadreza Fazel Najafabadi, Amirhossein Davarpanah Jazi

Abstract

• Cushing syndrome is one of the diseases associated with adrenals secreting too much cortisol. The syndrome was first described by Harvey Cushing in 1932.¹ It can be caused either by a tumor originating from the corticotroph cells located in pituitary glands, called corticotroph adenoma, or primary adrenal hyperplasia. It can be also the consequence of some other rare conditions such as ectopic corticotropin-releasing hormone (CRH) causing increased adrenocorticotropic (ACTH) secretion and macronodular adrenal hyperplasia (a primary pigmented nodular adrenal disease).^2,3 To manage the situation, previous articles demonstrated some strategies including two main groups of surgical treatments and non-surgical procedures.

  Surgical interventions are very important to completely cure this condition. Pituitary surgery, referred to as transsphenoidal operation, is the treatment of choice for patients with secondary disease.² However, in some situations, e.g. in patients with recurrent or persistent Cushing syndrome and those not responding to medical therapies after the surgery, the effectiveness of pituitary surgery is under question. Such patients are the best candidates for bilateral adrenalectomy. Some previous articles outlined this method.⁴ Laparoscopy is one of the methods recently used for adrenalectomy. During the surgery, some complications may occur which deteriorates patient's condition with noticeable rates of 9.5 to 12%. These complications are bleeding, organ damages, pain and deep vein thrombosis.^7,8
  
  Although in recent years the experts have achieved great improvements in management and treatment of the patients suffering from Cushing syndrome, some controversies still exist. In this manuscript, we explained a new method to accomplish a reliable bilateral adrenalectomy to manage the disease and cure the condition completely.

  After opening the abdomen, left adrenal gland is determined and adjacent vessels are ligated. Then, the enlarged adrenal gland would be entirely removed. However, adrenalectomy at the right side is not as simple as the left side. Renal vein detachment from the inferior vena cava can be a serious complication of right adrenalectomy if it is performed without enough exposure and experience. Massive bleeding in such clinical setting may significantly compromise patient's outcome. To avoid this complication during the procedure we can perform a new method explained below.
  Access to the right gland cannot be obtained by conventional retraction of the liver and it is necessary to mobilize the right hepatic lobe by fully incising the falciform ligament, the right triangular ligament, and rotating the right lobe medially. In this procedure, the bare area of the liver is dissected from the diaphragm. Care must be taken to avoid twisting and occluding the vena cava during this maneuver. After medial rotation of the liver in the proper position, the right adrenal and inferior vena cava can be directly visualized. This excellent exposure makes adrenalectomy very simple and minimizes the risk for renal vein detachment as a significant complication.

  This method was conducted on 6 cases admitted due to Cushing syndrome in Alzahra Hospital, Isfahan, Iran. While no major complications were observed, favorable outcomes were found in the 6-month follow-up period.

  Based on our experience, bilateral adrenalectomy via a midline incision is a promising and acceptable technique for patients with Cushing syndrome. However, due to excess adipose tissue and lack of enough exposure, adrenalectomy by lumbotomy in such patients has prominent limitations. Therefore, midline incision provides feasible exposure for direct visualization of both adrenals.

Endoscopic bilateral adrenalectomy (BLA) in patients with ectopic Cushing's syndrome

Alberda WJ, van Eijck CH, Feelders RA, Kazemier G, de Herder WW, Burger JW; Surgical Endoscopy (Nov 2011)

BACKGROUND: Bilateral adrenalectomy (BLA) is a treatment option to alleviate symptoms in patients with ectopic Cushing's syndrome (ECS) for whom surgical treatment of the responsible nonpituitary tumor is not possible. ECS patients have an increased risk for complications, because of high cortisol levels, poor clinical condition, and metabolic disturbances. This study aims to evaluate the safety and long-term efficacy of endoscopic BLA for ECS.

METHODS: From 1990 to present, 38 patients were diagnosed and treated for ECS in the Erasmus University Medical Center, a tertiary referral center. Twenty-four patients were treated with BLA (21 endoscopic, 3 open), 9 patients were treated medically, and 5 patients could be cured by complete resection of the adrenocorticotropic hormone (ACTH)-producing tumor. The medical records were retrospectively reviewed and entered into a database. For evaluation of the efficacy of BLA, preoperative biochemical and physical symptoms were assessed and compared with postoperative data.

RESULTS: Endoscopic BLA was successfully completed in 20 of the 21 patients; one required conversion to open BLA. Intraoperative complications occurred in two (10%) patients, and postoperative complications occurred in three (14%) patients. Median hospitalization was 9 (2-95) days, and median operating time was 246 (205-347) min. Hypercortisolism was resolved in all patients. Improvements of hypertension, body weight, Cushingoid appearance, impaired muscle strength, and ankle edema were achieved in 87, 90, 65, 61, and 78% of the patients, respectively. Resolution of diabetes, hypokalemia, and metabolic alkalosis was achieved in 33, 89, and 80%, respectively.

CONCLUSION: Endoscopic BLA is a safe and effective treatment for patients with ectopic Cushing's syndrome.
