About this study

Official title: Evaluation of Clinical Effectiveness, Quality of Life, and Compliance in Patients With Sickle Cell Disease Receiving Hydroxyurea

The aim of this single-center observational study was to evaluate quality of life, clinical effectiveness, and satisfaction in pediatric and young adult patients with sickle cell disease receiving hydroxyurea.

Read the detailed description

In this study, 34 pediatric (HbSS: n= 5; HbSβ0: n= 29) and 16 (HbSS: n=5; HbSβ0: n= 11) young adult adult patients with sickle cell disease receiving hydroxyurea for at least a year were participated. Upon receipt of Informed Consent Form, Case Report Form, Demographic Data Collection Form, Child Health Questionnaire-Parent Form, Life Quality Survey Short Form-36, and Hydroxyurea Therapy Satisfaction Survey were used to obtain data for effectiveness of hydroxyurea therapy and parameters that may affect compliance to treatment and life quality of the participants.

Regarding the normal ranges, ferritin, hemoglobin A, A2, F, and S, platelet, mean corpuscular volume, erythrocyte distribution width, basophil percentage, monocyte, monocyte percentage, total bilirubin, direct bilirubin, and C-reactive protein values were higher while hemoglobin, hematocrit, and erythrocyte values were lower in these patients. Our findings regarding quality of life and satisfaction with hydroxyurea therapy indicated that the patients with sickle cell disease had lower scores.

Demographic, clinical, and therapeutic variables as well as comorbid diseases and concomitant drug use when considered together, these findings suggest that the health quality and compliance of the pediatric and young adult patients to therapy might be low due to not sufficiently effective hydroxyurea therapy in addition to comorbidities, concomitant drug use, and side effects.

Questions about this trial

What is this clinical trial studying?

An observational study of Sickle Cell Disease, run by Mersin University at 1 site in Turkey (Türkiye).

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 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). 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?

Effectiveness and acceptance of hydroxyurea therapy in patients (time frame: Up to 12 weeks). 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 16 Aug 2016.
