目的分析库欣综合征患者的病因分类,各种主要临床表现的出现频率以及实验室检查特点,并对各种诊断方法的效率进行评价。方法收集2003~2008年在我院住院经临床和病理确诊为库欣综合征患者的病例资料,对它们进行回顾性分析。结果在本组病例中,库欣病最多见,肾上腺皮质腺瘤次之。临床表现方面,向心性肥胖和高血压出现的频率最高,均在70%以上。血糖异常和血脂异常的发生率分别为51.43%和70.59%,其中糖尿病的比例高达37.14%。四成以上的患者存在低血钾,肾上腺皮质腺癌患者100%有低血钾,且是重度低血钾。在库欣综合征诊断试验中,敏感性从高到低依次为不被小剂量地塞米松抑制,血皮质醇昼夜节律消失,24小时尿游离皮质醇增高,清晨血皮质醇增高。在库欣综合征患者的鉴别诊断中,80%以上的库欣病患者能被大剂量地塞米松抑制,而几乎94%的肾上腺皮质腺瘤患者不能被大剂量地塞米松抑制。有关影像学检查,垂体MRI可以检测出90%以上的库欣病患者存在垂体腺瘤,而肾上腺CT几乎100%可以发现出肾上腺肿瘤。结论本研究中库欣病和肾上腺皮质腺瘤仍然是最常见的病因,但后者的的比例相对较高。而在临床特点方面,高血压和糖尿病的发生率较高。对于库欣综合征的诊断和鉴别诊断,目前没有一种检查方法具有100%的敏感性,我们应对各种结果作出综合判断。  相似文献

In this study, 55 patients with Cushing's syndrome (CS) (50 female, 5 male; mean age 34 +/- 12.3 yr) who attended our clinics between the years 1983 and 2000 were retrospectively evaluated for clinical and laboratory features and modalities and results of therapy, due to a few similar studies over the last ten years. Cushing's disease was diagnosed in 39 patients (71%), adrenal adenoma in 13 patients (23.6%) and adrenal carcinoma in 3 patients (5.5%). Centripedal obesity, moon face, hypertension, hirsutism and purplish stria were the most frequent findings. Loss of normal serum F circadian rhythm was found in all patients with CS. The overnight 1 mg oral dexamethasone suppression test and low-dose dexamethasone suppression test (LDDST) yielded 100% and 100% diagnostic sensitivity for CS, respectively. Sensitivity and specivity of the high-dose dexamethasone suppression test (HDDST) in distinguishing Cushing's disease was found to be 82% and 100%, respectively. All of the patients with adrenal CS were not suppressed with HDDST. Sellar CT and/or MRI accurately identified the tumor in 58% of these patients. Recurrence was observed in 3 (11%) of the 28 patients with Cushing's disease, treated by transsphenoidal adenomectomy. Recurrence was diagnosed 1.5, 3 and 6 yr after the operation in these 3 patients. One patient had residue tumor. In our case series, bilateral adrenalectomy plus pituitary irradiation achieved the highest remission rate (100%) in Cushing's disease. In 2 out of 4 patients (50%) treated by left adrenalectomy associated with pituitary irradiation, recurrence was observed. Panhypopituitarism due to tumor apoplexy was observed in one of the patients with Cushing's disease. All of the patients with adrenal CS, the tumor was accurately localized with imaging methods before the operation. The appropriate operative procedure resulted in complete remission in patients with adrenal adenoma. Consequently, Cushing's disease was the most common form of CS. The overnight 1 mg oral DST and 24-h urine free F excretion (UFC) as screening tests, 2-day LDDST as diagnostic test and 2-day HDDST as differential diagnostic test were good studies. More successful outcomes have been achieved in treatment of Cushing's disease with the development of pituitary surgery in the recent years, as well as in our case series. Surgery is also curative for adrenal adenoma patients. Survival remains poor among carcinoma patients.  相似文献

STUDY OBJECTIVE: To determine the usefulness of the continuous intravenous dexamethasone suppression test in the differential diagnosis of patients with the Cushing syndrome. DESIGN: Comparison of the results of this test with those of other tests in the study population and with data from the literature. SETTING: Referral-based endocrine division in a university hospital. PATIENTS: One hundred and twenty-one patients with the Cushing syndrome were evaluated: corticotropin (ACTH)-secreting pituitary tumors, 90 cases; adrenal adenoma, 13; adrenal carcinoma, 9; ectopic ACTH-secreting tumors, 6; corticotropin-releasing-hormone (CRH)-secreting tumors, 2; and autonomous bilateral micronodular adrenal hyperplasia, 1. The continuous intravenous dexamethasone suppression test was done in 101 patients. MEASUREMENTS AND MAIN RESULTS: Dexamethasone (1 mg/h) was administered intravenously for 7 hours. A cortisol decrease of at least 190 nmol/L was defined as a positive response. In identification of patients with ACTH-secreting pituitary adenomas, this test had a sensitivity of 100% (95% CI, 95% to 100%), a specificity of 90% (CI, 70% to 99%), and a diagnostic accuracy of 98% (CI, 93% to 100%). Only two patients had false test results. They both had CRH-secreting tumors. Cortisol secretion was also shown to be sensitive for feedback control in other tests, however. CONCLUSION: The continuous intravenous dexamethasone suppression test has better diagnostic accuracy than other tests that are currently used in the differential diagnosis of the Cushing syndrome, and this test is very convenient. The only false test results were found in patients with CRH-secreting tumors.  相似文献

Obesity is prevalent worldwide and associated with co-morbidities that result in increased cardiovascular risk. Hypertension is the most prevalent obesity comorbidity associated with increased cardiovascular risk. Obesity hypertension is a distinct subtype of essential hypertension. While endogenous Cushing’s syndrome is an uncommon cause of both obesity and hypertension, the recent recognition of other hypercortisolemic states has raised the profile of hypercortisolism as an important contributor in obesity hypertension. The high prevalence of exogenous, iatrogenic, pseudo, and subclinical Cushing’s syndromes makes hypercortisolism an important diagnostic consideration in the evaluation and management of patients with obesity hypertension who are resistant to conventional management. Available data suggest that the renin-angiotensin-aldosterone system modulating antihypertensives have the best efficacy in hypercortisolism-mediated obesity hypertension. Strategies aimed at reducing cortisol production and action also have utility. This review provides a comprehensive overview of the epidemiology, etiopathogenesis and management options available for glucocorticoid-mediated obesity hypertension.  相似文献

A 69-year-old female patient had been treated with glucocorticoid for eight years because of rheumatoid arthritis. She showed characteristic Cushingoid features such as central obesity, moon face, and fragility of skin and vessels. She was disabled because of spinal compression fracture and muscle weakness. The blood pressure was 186/100 mmHg and the laboratory tests revealed serum K: 2.8 mEq/l, WBC: 15, 510/mm3, total cholesterol: 310 mg/dl. These suggested that she had iatrogenic Cushing's syndrome. After discontinuation of glucocorticoid, however, the serum cortisol level remained high. This fact prompted us to conduct further examinations for Cushing's syndrome. Oral dexamethasone administration did not suppress the plasma cortisol level and a left adrenal adenoma was found on abdominal CT scan. Because of the presence of bleeding diathesis, operation for adenoma was contraindicated. Though we tried to treat her with metyrapone, trilostane or opeprim (OP'-DDD), we had to abandon specific treatment because of severe side effects such as acute adrenal dysfunction and gastrointestinal problems. Decrease in the endogenous cortisol level after metyrapone treatment caused exacerbation of symptoms of rheumatoid arthritis. This is a peculiar case in which the long-term administration of glucocorticoid for rheumatoid arthritis might have concealed Cushing's syndrome, and conversely the increased intrinsic adrenal steroid hormone might have suppressed the activity of the rheumatoid arthritis.  相似文献
