Trial summary

Chronic kidney disease (CKD) patients often have associated systemic hypertension due to volume retention, as one of the mechanisms, therefore the use of diuretics is widespread in this population. Read more about this study

About this study

Official title: The Effect of Thiazide and Loop Diuretic on Mineral and Bone Disorder in Chronic Kidney Disease Patients

Chronic kidney disease (CKD) patients often have associated systemic hypertension due to volume retention, as one of the mechanisms, therefore the use of diuretics is widespread in this population. One of the major complications of CKD is mineral and bone metabolism disorder (CKD-MBD), which include changes in the levels of calcium, phosphorus, vitamin D deficiency, increased circulating levels of fibroblast growth factor (FGF-23) and parathyroid hormone (PTH). These alterations are responsible for fractures, cardiovascular disease and mortality among patients with CKD. According to diuretic mechanism of action, sometimes increasing serum calcium (in the case of furosemide), sometimes decreasing it (in the case of thiazide), it is expected that the serum calcium may be altered, even within the range of normality, with consequent impact on the levels of PTH. Although most studies have shown that the use of thiazide diuretics decreases the risk of fractures, some showed the opposite. Similarly, although most studies have shown increased risk of fracture in association to loop diuretics use, some have failed in demonstrated this outcome. Only one study, a cohort study in a population of CKD, showed that furosemide was directly related to increased calciuria and PTH levels and the use of thiazide, in turn, showed completely opposite effect. However, certain issues are still not completely solved, for example, the interference of renal function itself on calciuria. It is possible that calciuria is not a so simple explanation that justifies the PTH levels changes, as no correlation was seen between calciuria and PTH levels. Better understanding of the exact relationship between the use of diuretics and the impact on CKD-MBD may be an alternative intervention, easily accessible and relatively inexpensive. The purpose of this study is to evaluate the impact of diuretic, specifically hydrochlorothiazide and furosemide, on bone architecture and mineral metabolism.

Read the detailed description

This is a prospective randomized study to test the effects of thiazide and furosemide in bone parameters, which will be assessed by peripheral micro-tomography at baseline and 12 months later. The role of calciuria in these possible changes will be tested.

Questions about this trial

What is this clinical trial studying?

A study testing Hydrochlorothiazide and Furosemide in people with Secondary Hyperparathyroidism and Chronic Kidney Disease, run by University of Sao Paulo General Hospital at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 26 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Rosilene M Elias, M.D., Ph.D (+5511 26617167, rosilenemotta@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Parathyroid hormone (PTH) level. (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2017.
