Hyperuricaemia in sickle cell disease

Area of Science:

• Pediatric Hematology
• Biochemistry
• Clinical Chemistry

Background:

• Sickle cell disease (SCD) is a genetic blood disorder.
• Hyperuricemia, or high uric acid levels, is a known complication in some chronic diseases.
• The relationship between SCD and uric acid levels in children requires further elucidation.

Purpose of the Study:

• To determine serum uric acid levels in children with homozygous sickle cell disease.
• To compare these levels with those of a healthy pediatric control group.
• To discuss the implications of observed uric acid level differences.

Main Methods:

• Serum uric acid levels were measured using the uricase method.
• The study included 69 children under 11 years with homozygous sickle cell disease.
• A control group of healthy children in the same age range was used for comparison.

Main Results:

• A statistically significant difference in mean serum uric acid levels was observed between the groups.
• 28% of children with sickle cell disease had uric acid levels exceeding the upper normal limit of controls.
• This indicates a higher prevalence of elevated uric acid in pediatric SCD patients.

Conclusions:

• Children with homozygous sickle cell disease exhibit significantly higher serum uric acid levels.
• Elevated uric acid may be a notable biochemical finding in pediatric SCD.
• The clinical implications of these findings warrant further investigation and discussion.
