Insights
Hydroxyurea significantly improves health-related quality of life (HRQOL) in children with sickle cell disease (SCD). This study in Oman found hydroxyurea use led to better HRQOL outcomes compared to non-use.
Area of Science:
- Pediatric Hematology
- Quality of Life Research
- Pharmacological Interventions
Background:
- Sickle cell disease (SCD) is a genetic blood disorder requiring comprehensive management.
- Hydroxyurea is a recommended treatment for SCD, known to increase fetal hemoglobin production and reduce complications.
- Limited research exists on hydroxyurea's impact on health-related quality of life (HRQOL) in Omani children with SCD.
Purpose of the Study:
- To evaluate differences in HRQOL between children with SCD who received hydroxyurea and those who did not.
- To assess the effectiveness of hydroxyurea in improving HRQOL among pediatric SCD patients in Oman.
Main Methods:
- A cross-sectional study involving 74 children diagnosed with SCD from a tertiary hospital in Oman.
- Data collection utilized two questionnaires: HRQOL-SCD and HRQOL-Generic.
- Statistical analysis included one-way analysis of variance and regression analysis.
Main Results:
- Children receiving hydroxyurea demonstrated significantly higher HRQOL scores compared to those not on the medication (p=0.001).
- Hydroxyurea was identified as a significant predictor of improved HRQOL in children with SCD.
- Factors including parental familiarity, self-efficacy, child age, sex, and hydroxyurea use explained 87% of the variability in child-reported HRQOL.
Conclusions:
- Hydroxyurea treatment positively impacts the HRQOL of children with SCD.
- Findings support the expanded use of hydroxyurea in pediatric SCD management to enhance quality of life and decrease vaso-occlusive events.
- Recommendations include enhancing parental education on hydroxyurea and implementing strategies to improve medication adherence for optimized SCD care.
Objectives:
Hydroxyurea is been recommended for patients with sickle cell disease (SCD) as it reduces the complications from the disease by increasing the production of fetal hemoglobin. In Oman, hydroxyurea is not consistently prescribed to children with SCD, and limited research has compared the health-related quality of life (HRQOL) among children prescribed hydroxyurea. Thus, this study evaluated HRQOL differences between children with SCD who received hydroxyurea and those who did not.
Methods:
A cross-sectional study was conducted on children from a hematology clinic at a tertiary hospital in Oman. We collected the data using two questionnaires: HRQOL-SCD and HRQOL-Generic. A one-way analysis of variance was used for statistical analysis.
Results:
A total of 74 children (47.3% male and 52.7% female) completed the questionnaire; 33 children were on hydroxyurea and 41 were not. A significant difference in HRQOL scores was found between children receiving hydroxyurea and those not taking the drug [F (1,68) = 419.4; p-value = 0.001]. Regression analysis revealed that hydroxyurea was a significant predictor of improved HRQOL among children with SCD. An R2 of 0.87 indicated that 87.0% of the variability in the child-reported HRQOL-Generic was explained by parental familiarity, self-efficacy, child age, sex, and receiving hydroxyurea [R2 = 0.87, F (8,69) = 52.4; p-value < 0.001].
Conclusions:
Hydroxyurea improved the children's HRQOL compared to those who did not receive the drug. These findings support the use of hydroxyurea in children to improve HRQOL and reduce vaso-occlusive episodes. We recommend increasing parents' understanding of hydroxyurea's significance and devising strategies to promote children's medication adherence. It is essential to modify the SCD management protocol to optimize the HRQOL among children with SCD.
