About this study

Official title: Serum Brain Natriuretic Peptide Levels and Its Correlation With Echocardiographic Measurements Suggestive of Pulmonary Hypertension in Pediatric Patients With Sickle Cell Disease

The purpose of this study is

  1. To determine if Brain natriuretic peptide levels correlates with elevated tricuspid regurgitation flow velocity levels in pediatric patients with sickle cell disease
  2. To determine the role of age, gender, steady state hemoglobin and disease type on Brain natriuretic peptide levels and pulmonary hypertension
Read the detailed description

Pulmonary hypertension is recognized as a significant cause of morbidity and mortality in patients with sickle cell disease. Doppler echocardiography is a recommended noninvasive screening tool for sickle cell disease patients with pulmonary hypertension. Brain natriuretic peptide levels have been found to be a possible serum screening marker. This research will offer the opportunity to determine if there is any possible relationship between magnitude of BNP concentration and degree of TRV, if it can be used as a screening test in SCD pediatric patients with PHT and form the basis for a future multicenter study

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation of Brain Natriuretic Peptide (BNP) levels to elevated Tricuspid Regurgitation Flow Velocity (TRV)

    Subjects will be asked to participate in the study by allowing a review of their echocardiographic findings. In addition, they will be asked for a 1 ml blood sample during routine annual follow ups for BNP levels to be drawn.

    Measured: one day

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Hypertension, run by Akron Children's Hospital at 1 site in United States.

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 4 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: finished, as of the sponsor's last update on 26 Jun 2014. 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 United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation of Brain Natriuretic Peptide (BNP) levels to elevated Tricuspid Regurgitation Flow Velocity (TRV) (time frame: one day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01023451, which also lists 5 linked publications.

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 Jun 2014.
