| | Abstract | We experienced 41 cases of Cushing's syndrome (12 males and 29 females, 15 years old - 65 years old) during the last 20 years. These included 20 patients with unilateral adrenal adenoma (Cushing's syndrome), 19 patients with bilateral adrenal hyperplasia (Cushing's disease), one patient with adrenal carcinoma and one patient with primary adrenocortical nodular dysplasia (PAND). Moreover, these cases included some special ones, i.e. 5 cases with destructive thyroiditis after treatment, 2 cases with aggravation of arthritis after treatment, a case of Carney's complex with PAND, one case with paradoxical response to dexamethasone, and one case combined with empty sella syndrome. The most specific clinical signs were moon face (95% occurrence), hypertension (95%) and subcutaneous bruising (80%). Other significant signs were eye edema (66%), buffalo hump (68%), subcutaneous purpura (63%) and osteoporosis (49%). Skin striae was not a common sign in our cases (41%). Renal stone was observed in only 20% of our patients but was a significant sign in this syndrome. There was no difference in the occurrence of each clinical sign between Cushing's syndrome and Cushing's disease. The elevation of white blood cell count (WBC) and serum sodium, a decrease of serum potassium, and a decrease of reabsorption of phosphate (%TRP) were observed. Thyroid-stimulating hormone (TSH) and human growth hormone (HGH) were suppressed in patients with Cushing's syndrome and patients with Cushing's disease. These results were consistent with those of previous reports. However, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin (PRL) were high in those patients with Cushing's syndrome and those with Cushing's disease. Oral glucose tolerance test was carried out in 34 patients before and after treatment. Thirty-one percent of those had diabetes mellitus and 26% had impaired glucose tolerance (IGT). The response of IRI in this test was high in patients with Cushing's syndrome and patients with Cushing's disease, and decreased 4 weeks after treatment in those with Cushing's syndrome but remained high in those with Cushing's disease. Plasma ACTH level and urinary 17-OHCS excretion were significantly higher in Cushing's disease than in Cushing's syndrome. During an 8mg-high-dose dexamethasone suppression test, urinary 17-OHCS excretion in 13 of 14 patients with Cushing's disease (93%) was suppressed by more than 50% of baseline on the second day of testing. However, all of 18 patients with Cushing's syndrome, who had an 8mg-dexamethasone suppression test, failed to suppress urinary 17-OHCS by 50% of baseline.(ABSTRACT TRUNCATED AT 400 WORDS) | | Language | jpn | | Pub Type(s) | Journal Article
