Trial summary

Sickle Cell Disease is a serious disease that is life-threatening for patients being homozygous for the SS form or heterozygous for the SC or βthal forms.

About this study

Sickle Cell Disease is a serious disease that is life-threatening for patients being homozygous for the SS form or heterozygous for the SC or βthal forms. The CHU Brugmann hospital currently regularly treats about 70 homozygous adult patients and this number is in constant augmentation.

Sickle cell disease patients may develop a cardiomyopathy due to chronic anemia, the haemosiderosis risk or, less frequently, to coronary vaso-occlusive damages.

The hypervolemia in patients with sickle cell disease causes an overestimation of the ejected left ventricular fraction measured by echocardiography, this parameter being very dependent of the blood volume.It has already been shown that the left ventricular ejection fraction was normal in most patients with sickle cell disease, but that its evaluation by parameters independent from the blood volume showed the existence of a dysfunction.

Myocardial strain, as measured by speckle tracking, is a echographic evaluation method of the cardiac function, independent of the blood volume. This technique hasn't been used much in sickle cell disease patients. A study using 3D speckle tracking on a limited number of sickle cell disease patients failed to show a strain anomaly. Moreover, the study highlighted a higher global longitudinal strain in this patient population. The investigators find these data hard to explain and in contradiction with previous studies using other cardiac function evaluation techniques, independent from the blood volume.

The primary goal of this study is thus

  • to study the longitudinal strain by 2D echography
  • to determine if anomalies of the longitudinal strain exist in sickle cell disease patients with a normal ejected left ventricular fraction, compared to a control group of healthy patients.

The secondary goal of this study is to correlate, inside the sickle cell disease group, the possible strain anomalies with biological gravity parameters of the disease.

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?

Cardiac ejection fraction (time frame: once per year, at the annual medical visit planned according to the standart of care for this pathology). The study lists 7 primary outcomes in all. 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 NCT02394431, which also lists 6 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 Jul 2016.
