Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the blood pressure lowering effects of thiazide diuretics in patients on peritoneal dialysis

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This prospective, single-center treatment-withdrawal crossover study enrolled 10 patients on chronic peritoneal dialysis (PD) and uncontrolled hypertension (SBP \>140 mmHg and/or DBP \>90 mmHg).

Following written informed consent, participants entered the treatment arm, receiving oral hydrochlorothiazide once daily on top of their standard of treatment for 90 days. This was followed by a 14-day washout period, after which participants entered a 90-day control period.
