About this trial
Chronic kidney disease (CKD) is associated with a higher risk of cardiovascular disease and death. An overactive sympathetic nervous system in CKD patients is one of the major mechanisms increasing the cardiovascular risks in this patient population. Recently, some studies have shown that a drug typically used to improve glucose control (pioglitazone) may also reduce sympathetic nerve activity and improve blood vessel function.
The goal of this study is to determine whether a short-term treatment with pioglitazone can reduce sympathetic nerve impulses throughout the body in CKD patients.

Trial outcomes
Primary outcomes
Muscle sympathetic nerve activity (MSNA) will be reduced after 1 month of treatment with pioglitazone
Multiunit postganglionic MSNA will be recorded using standard microneurographic techniques. Briefly, a unipolar tungsten microelectrode will be inserted into the peroneal nerve near the fibular head of the leg. Neural signals will be amplified, filtered (bandwidth, 700-2,000 Hz), rectified, and integrated (time constant, 0.1 s) to obtain mean voltage neurograms.
