Cholelithiasis in children with sickle cell disease

Abdominal ultrasonography was performed on 305 children with sickle cell disease (SCD) (285 SS and 20 S-beta-thalassemia) to establish the prevalence of cholelithiasis in Saudi children with SCD. Their ages ranged from 1 to 18 years (mean 10.45 years). Gallstones were demonstrated in 60 children, giving a prevalence of 19.7%. An additional 50 patients (16.4%) had only biliary sludge. The youngest patient with gallstones was 3 years old. There was a correlation between the presence of gallstones and increasing age. Patients with gallstones were also found to have higher serum bilirubin levels, but their hemoglobin, hematocrit, reticulocyte count, hemoglobin S, and hemoglobin F levels were not significantly different from those of patients without gallstones.
