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.

Experimental Treatment
Group I: Diuretic augmentationExperimental Treatment1 Intervention
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.

Other Research
Common treatments for Chronic Kidney Disease (CKD) include diuretics, ACE inhibitors, angiotensin receptor blockers (ARBs), and calcium channel blockers. Diuretics increase urine production to remove excess fluid, reducing volume overload and the risk of cardiovascular complications.
ACE inhibitors and ARBs relax blood vessels and lower blood pressure, decreasing the workload on the kidneys and slowing disease progression. Calcium channel blockers also lower blood pressure by relaxing blood vessels.
These treatments are essential for managing symptoms, preventing complications, and slowing the progression of CKD.
