Abstract
Background and Aim: Sickle cell disease (SCD) is a crucial and growing global health
problem. Kidney damage is one of the most common complications of SCD. This study
aimed to determine the prevalence of acute kidney injury (AKI) in children with SCD.
Methods: This cross-sectional and analytical study was conducted from January 2022 to
September 2022. It included children with SCD aged 6 months to 17 years during their steady
state. We measured the estimated glomerular filtration rate (eGFR) using the combined
creatinine and cystatin C formula for kids (CKiDScr-Cys C). Univariate analyses were performed
to measure the relationship between variables and AKI and eGFR, followed by a multivariate
analysis using logistic regression.
Results: Of the 137 children, 82 (60%) were boys and 55 (40%) were girls. The mean eGFR
was 112±45.3 mL/min/1.73 m2. A total of 36 subjects, or 26.3% (95% confidence level [CI],
18.9, 33.6%), had acute AKI. Comparison of characteristics by AKI status showed significant
differences in the number of transfusions (P<0.01) and hemoglobin level (P<0.027). eGFR
was negatively correlated with the number of transfusions (r=-0.308; 95% CI, -0.477%,
-0.117%; P<0.01). Multivariate analysis showed that nutritional status was a protective factor
for AKI (P<0.01), and the number of transfusions was a predictive factor of AKI in SCD
(P<0.001).
Conclusion: The results of our study are an urgent call to implement existing management
programs for SCD, from screening to universal access to hydroxyurea, to reduce complications
and mortality related to this pathology.
