DOCK Trial Summary

This trial will study whether treating early kidney disease with diuretics can improve long-term cardiovascular outcomes.

Who is the study for?
This trial is for Veterans with early-stage chronic kidney disease (CKD stages 1-3) who have high blood pressure. Participants must be at least 18 years old, able to give informed consent, and not on dialysis or a recipient of a kidney transplant. Those with severe heart issues, liver cirrhosis, major limb amputation, pregnancy, or certain devices like pacemakers are excluded.Check my eligibility
What is being tested?
The study tests whether diuretics (like hydrochlorothiazide or furosemide) can reduce fluid overload in the body and improve cardiovascular health in people with early CKD. It compares two methods of measuring fluid overload and observes changes in symptoms and short-term heart function after treatment.See study design
What are the potential side effects?
Diuretics may cause dehydration, electrolyte imbalances (like low potassium), dizziness upon standing up due to lowered blood pressure, increased urination frequency, fatigue, muscle cramps or weakness.

The participant's blood pressure medication regimen will be altered to initiate a thiazide-type or loop diuretic in those not already prescribed a diuretic, or to increase the dose if one is already prescribed.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How many participants are the researchers expecting to recruit for this experiment?

"At this time, the trial is no longer enrolling patients. It was initially posted on February 1st 2023 and last modified on November 16th 2022. For those still searching for a suitable study, there are presently 1211 clinical trials focused on hypertension and 31 studies involving Diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide or bumetanide) that are actively recruiting participants."

Answered by AI

Are individuals eligible to join this experiment presently?

"Unfortunately, this medical trial is no longer actively seeking participants. The original posting was on February 1st 2023 and the most recent update came November 16th 2022. However, if you are looking for additional studies there are 1211 trials recruiting patients with hypertension and 31 which require augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide or bumetanide)."

Answered by AI

Is the FDA sanctioning Diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide, or bumetanide) as a viable treatment?

"The efficacy and safety of diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide or bumetanide) have been adequately demonstrated in clinical trials; thus receiving a score of 3."

Answered by AI

To which conditions is diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide, or bumetanide) generally prescribed?

"Diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide or bumetanide) is a common approach to treating edema and serves as an intervention for cerebrovascular accident, antihypertensive agents and kidney diseases."

Answered by AI

What other research projects have examined the effectiveness of diuretic augmentation involving hydrochlorothiazide, chlorthalidone, furosemide, torsemide or bumetanide?

"Currently, 31 medical trials are underway to analyse the effectiveness of Diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide, or bumetanide). 11 of these studies have reached Phase 3. While Halifax has several sites conducting this research, there is a total 132 clinical trial locations across North America researching Diuretic augmentation (hydrochlorothiazide, chlorthalidone, furosemide, torsemide, or bumetanide)."
