Aim of our study was to assess the potential effects of high-tone external muscle stimulation (HTEMS) on improvement of endothelial dysfunction (ED) and kidney damage in elderly patients with chronic kidney disease (CKD), sarcopenia and/or serious physical disability with a high Multidisciplinary Prognostic Index (MPI). METHODS: We enrolled 12 consecutive CKD patients with MPI > 0,66 from January 1st, 2008 to December 31st, 2014. Six patients underwent a 2-hours HTEMS during the first day (group A) and the other six patients (group B) underwent a sham experiment with HTEMS without power supply. After 24 hours, patients of group A were shifted to group B and viceversa. Nitrite/nitrate (NOx), endotheline-1 (ET-1) and urine creatinine concentration were measured in all patients. RESULTS: During HTEMS urine amount increased by 22% (p=0.049), so did urine creatinine that increased by 40%, (p=0.034) and creatinine clearance that increased by 26% (p=0.041). There was no statistical difference in urine nitrogen (that raised by 11%, p=0.526), urine sodium (that reduced by 42%, p=0.121) and urine potassium levels (p=0,491). At the same time, NOx changed from 44.15.1 to 38.45.3 M/L after 1 hour, to 36.44.8 M/L after 2 hours, to 41.15.7 M/L after 3 hours and to 46,95.0 M/L after 4 hours (p=0.008) during HTEMS, while it did not vary during the sham section of the experiment, respectively 43.66.1 M/L , 436.4 M/L, 42.85.5 M/L, 434.7 M/L, and 42.85.8 M/L (p=0.992). CONCLUSION: Our study showed that HTEMS may improve microcirculation and, through this mechanism, may reduce kidney damage in elderly patients with CKD and severe muscle atrophy.

Abstract

Aim of our study was to assess the potential effects of high-tone external muscle stimulation (HTEMS) on improvement of endothelial dysfunction (ED) and kidney damage in elderly patients with chronic kidney disease (CKD), sarcopenia and/or serious physical disability with a high Multidisciplinary Prognostic Index (MPI). METHODS: We enrolled 12 consecutive CKD patients with MPI > 0,66 from January 1st, 2008 to December 31st, 2014. Six patients underwent a 2-hours HTEMS during the first day (group A) and the other six patients (group B) underwent a sham experiment with HTEMS without power supply. After 24 hours, patients of group A were shifted to group B and viceversa. Nitrite/nitrate (NOx), endotheline-1 (ET-1) and urine creatinine concentration were measured in all patients. RESULTS: During HTEMS urine amount increased by 22% (p=0.049), so did urine creatinine that increased by 40%, (p=0.034) and creatinine clearance that increased by 26% (p=0.041). There was no statistical difference in urine nitrogen (that raised by 11%, p=0.526), urine sodium (that reduced by 42%, p=0.121) and urine potassium levels (p=0,491). At the same time, NOx changed from 44.15.1 to 38.45.3 M/L after 1 hour, to 36.44.8 M/L after 2 hours, to 41.15.7 M/L after 3 hours and to 46,95.0 M/L after 4 hours (p=0.008) during HTEMS, while it did not vary during the sham section of the experiment, respectively 43.66.1 M/L , 436.4 M/L, 42.85.5 M/L, 434.7 M/L, and 42.85.8 M/L (p=0.992). CONCLUSION: Our study showed that HTEMS may improve microcirculation and, through this mechanism, may reduce kidney damage in elderly patients with CKD and severe muscle atrophy.
