Quality of Life in Greek Hemodialysis Patients Receiving Zemplar i.v (QualitiZe)

The purpose of this study is to assess health-related Quality of Life (QoL) changes in participants with chronic kidney disease (CKD) and secondary hyperparathyroidism (sHPT) undergoing hemodialysis and receiving paricalcitol intravenous (iv).

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The scientific purpose of this study is to obtain data on the use of paricalcitol iv in real-life clinical practice and the effect it has on participant health-related QoL. In this study, paricalcitol iv will be prescribed on an on-label basis in an everyday setting. The RAND 36-Item Health Survey results will be collected for a 6-month period (every 3 months) in order to assess the effect of paricalcitol iv on participant health-related QoL.
