Insights
Serum uric acid levels were elevated in Iraqi children with sickle cell disease (SCD). Urea and creatinine levels were lower in SCD patients compared to controls, suggesting potential renal function changes.
Area of Science:
- Pediatrics
- Nephrology
- Hematology
Background:
- Sickle cell disease (SCD) is a genetic blood disorder.
- Renal complications are common in SCD patients.
- Serum uric acid, urea, and creatinine are indicators of kidney function.
Purpose of the Study:
- To determine serum uric acid, urea, and creatinine levels in children with SCD.
- To compare these levels with those in healthy children.
- To assess potential renal function alterations in pediatric SCD.
Main Methods:
- Study conducted in Basrah, Iraq.
- Included 65 children with SCD (Hb AS and Hb SS) aged 2-11 years.
- Compared biochemical markers with 45 age and sex-matched healthy controls (Hb AA) using Varley's method.
Main Results:
- Elevated serum uric acid levels were observed in SCD patients compared to controls (p < 0.0001).
- Urea and creatinine levels were significantly lower in SCD patients (Hb SS and Hb AS) than in controls (p < 0.0001).
- Statistical significance was high for all comparisons.
Conclusions:
- Iraqi children with SCD exhibit elevated serum uric acid.
- Lower urea and creatinine levels in SCD patients warrant further investigation.
- Creatinine clearance studies are recommended to evaluate renal function in pediatric SCD.
Objective:
To determine the levels of serum uric acid, urea and creatinine in subjects with sickle cell disease and compare them to those reported in literature.
Setting:
Department of Paediatrics, College of Medicine, University of Basrah.
Methods:
Plasma uric acid, urea and creatinine was estimated by Varley's method, group of 65 sickle cell patients (35 Hb AS, 30 Hb SS) aged between 2-11 years. The results were compared with those obtained in a group of 45 age and sex-matched controls with normal haemoglobin (Hb AA).
Results:
The uric acid level was elevated in sickle cell patients as compared with the normal control group. The 95% confidence intervals for differences in the mean of the two groups: HbAA vs HbAS was 4.22 (0.3), while for HbAA for HbSS was 3.4 (0.06), both being statistically highly significant [p < 0.0001]. Urea and creatinine levels were considerably lower in the sickle cell disease patients. The difference in the patient's mean for urea compared to the mean in the normal group (Hb AA) was 9.64 (1.95) and 8.55 (1.76) for HbSS and HbAS, respectively. Like wise, the difference in the mean for creatinine in HbSS group was 0.71 (0.12) and in HbAS was 0.76 (0.12), which was statistically significant [p < 0.0001].
Conclusion:
Raised serum uric acid levels were found in Iraqi children with sickle cell disease, creatinine clearance studies will be valuable to assess renal function.
