The age-dependent decrease in muscle mass and function is known as sarcopenia. The risk of sarcopenia is higher in patients with diabetes, and assessment of muscle mass and function is especially important in patients with diabetes. Recent reports suggest that the phase angle (PhA), which is obtained from bioelectrical impedance analysis (BIA), may be a good marker of not only muscle mass but also muscle function in healthy people. However, the clinical significance of PhA in patients with diabetes has not been fully investigated. Therefore, we evaluated the association of PhA with muscle mass, muscle strength, and physical performance in 159 patients with type 2 diabetes (male 102; female 57) aged 40 to 89 years. We measured PhA and appendicular skeletal muscle index (SMI) by BIA and handgrip and leg extension strength and performed the Short Physical Performance Battery (SPPB). In a simple correlation analysis, both right and left PhA correlated with SMI, handgrip and leg extension strength, and SPPB score, and in multiple regression analysis, PhA on each side correlated with SMI and ipsilateral handgrip strength. These data suggest that PhA may be a useful marker of muscle mass, muscle strength, and physical performance in patients with type 2 diabetes. A large-scale prospective study should be performed to confirm the results and clarify the clinical usefulness of PhA in patients with diabetes.

The Research Committee of Disorders of Adrenal Hormones, Japan, undertook a nationwide epidemiological study of primary aldosteronism (PA). The present study was undertaken as a part of this study to reveal the relationship between type of treatment and the prognosis of PA. In the primary survey, 4161 patients with PA during the period January 1, 2003-December 31, 2007 were reported from 3252 departments of internal medicine, pediatrics and urology. In the secondary survey, a questionnaire that requested detailed clinical information on individual patients was sent to those departments reporting patients in the primary survey. In total, data on 1706 patients with PA were available in the present study. Among patients with bilateral or unilateral aldosterone-producing adenoma, after adjustment for age at which prognosis was examined, sex, surgical treatment and medical treatment, surgical treatment was significantly associated with amelioration of hypertension (adjusted odds ratio [OR]: 0.47 [95% confidence interval (CI): 0.29–0.77]) and hypokalemia (adjusted OR: 0.17 [95% CI: 0.11–0.29]). No significant relationship was observed between medical treatment and such prognosis in this group of patients. Among patients with bilateral or unilateral adrenal hyperplasia, surgical, but not medical, treatment was significantly associated with amelioration of hypokalemia (adjusted OR: 0.23 [95% CI: 0.06–0.74]), while there was no relationship between surgical or medical treatment and the prognosis of hypertension. In conclusion, surgery offered a better prognosis of PA than medication with regards to hypertension and hypokalemia, with the limitation that a new anti-aldosterone drug, eplerenone, was not available during the study period.
