BACKGROUND Microneurographic recordings of muscle sympathetic nerve activity (MSNA) have shown that sympathetic activation may characterize diabetes mellitus. However, it is recognized that comorbidities and metabolic abnormalities frequently associated with both type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) diabetes affect MSNA, generating potential confounding effects and making the association between sympathetic activation and diabetes mellitus still a controversial matter. METHODS The present meta-analysis evaluated 11 microneurographic studies enrolling 314 diabetes mellitus patients and healthy controls, and MSNA was chosen as the main variable of interest. Collection of the data included indirect adrenergic markers such as heart rate and venous plasma noradrenaline, together with hemodynamic, anthropometric and metabolic variables. RESULTS A total of 11 microneurographic studies were evaluated including 314 diabetes mellitus patients and controls. Diabetes mellitus displayed MSNA significantly greater than controls (mean difference amounting to 8.1, 95% confidence interval 1.21-15.08, P

BACKGROUND: Studies based on microneurographic sympathetic nerve activity (MSNA) recordings have shown that the sympathetic system is overactivated in chronic kidney disease (CKD) patients but the relationship between MSNA and renal function and other risk factors has not been systematically reviewed in this population.DESIGN AND MEASUREMENTS: This meta-analysis compares MSNA in cardiovascular complications-free CKD patients (n = 638) and healthy individuals (n = 372) and assesses the relationship of MSNA with the eGFR, age, BMI and hemodynamic variables.RESULTS: In a global analysis, MSNA was higher in CKD patients than in healthy control individuals (P

Objective:Nerve traffic recordings (MSNA) have shown that sympathetic activation may occur in obese individuals (O). However, the small sample size of the available studies, presence of comorbidities, including sleep apnea, heterogeneity of the patients examined as well as presence of confounders re

Objective:The microneurographic technique has shown that sympathetic overactivity may characterize individuals with metabolic syndrome (MS). However, technical and methodological limitations of the published studies (small sample size, presence of comorbidities including sleep apnea, presence of mul
