        Objectives: Microalbuminuria predicts cardiovascular mortality in patients with non-insulin-dependent diabetses mellitus (NIDDM). Microalbuminuria is frequently associated with high blood pressure, dyslipidemia, insulin resistance and central obesity, and has been suggested to be a feature of metabolic syndrome (syndrome X). Metabolic syndrome is also present in Cushings syndrome, which is characterized by primary hypercortisolism as well as profound visceral obesity. Considering common features of Cushings syndrome and metabolic syndrome, microalbuminuria could be a feature of Cushings syndrome. Methods ' We studied urinary albumin excretion (UAE) in 13 patients with Cushings syndrome, UAE was reexamined after the correction of hypencortisolemia in the patients with microalbuminuria or overt proteinuria. Kidney biopsy was performed in 3 patients with microalbuminuria. Hesults: Eight out of 13 patients (61.5 %) had microalbuminuria. Kidney biopsy revealed apparently normal glomerular structures without evidence of diabetic or hypertensive nephropathy. Patients underwent successful removal of pituitary or adrenal tumors and were reevaluated 2 months after surgery. TJAE declined profoundly in all of the patients with initial microalbuminuria. . Conclusion - Our results demonstrate that more than 60% of patients with Cushings syndrome have microalbuminuria. This rate far exceeds the rate in NIDDM patients and hypertensive patients. Microalbuminuria nearly completely reversed after successful treatment of hypercortisolism.

        Background : The zonal differentiation of hepatic necrosis is important in the aspect of treatment, follow-up and prognosis of patients. The purpose of this study was evaluating the clinical usefulness of serum isocitrate dehydrogenase (ICDH) as a marker of centrilobular hepatic necrosis in patients with hyperthyroidism. Methods : We determined the serum ICDH and alanine aminotransferase (ALT) activities in 56 patients with hyperthyroidism, 16 patients with chronic viral hepatitis, and 17 normal controls. Results : The activities of serum ICDH were significantly higher in patients with hyperthyroidism than those of patients with chronic viral hepatitis or normal control (p<0.01), even though those of serum ALT were higher in patients with chronic viral hepatitis (p<0.01). The ratio of serum ICDH and ALT activities were markedly different between the patients with hyperthyroidism and chronic viral hepatitis (p<0.001). There was a significant correlation between the serum ICDH and ALT activities in patients with hyperthyroidism as well as in those with chronic viral hepatitis (p<0.05). In patients with hyperthyroidism, the serum ICDH levels were more significantly correlated with serum triiodothyronine (T3) than thyroxine (T4) levels. In a patients with hyperthyroidism and elevated ALT levels, the serum ICDH activity decreased progressively and was normalized ultimately, as serum ALT level and thyroid function were normalized with antithyroid medication. Conclusion : The serum ICDH or ratio of serum ICDH and ALT activities might be useful clinically in differentiating the centrilobular from periportal hepatic necrosis, and following up the degree of hepatic necrosis in patients with hyperthyroidism.(Korean J Med 58:189-196, 2000)
