Insights
Gallstones are common in sickle cell disease patients. While many develop gallstones, few require surgery, indicating a low morbidity rate for symptomatic gallstones in this population.
Area of Science:
- Hematology
- Gastroenterology
- Pediatrics
Background:
- Sickle cell disease (SCD) is a group of inherited red blood cell disorders.
- Gallstones (cholelithiasis) are a known complication of SCD.
- Understanding gallstone development and clinical impact is crucial for patient management.
Purpose of the Study:
- To determine the prevalence, incidence, and risk factors of gallstones in patients with homozygous sickle cell disease (HbSS) and sickle cell-hemoglobin C disease (HbSC).
- To assess the clinical associations and morbidity related to gallstones in these SCD populations.
- To evaluate the need for cholecystectomy in affected individuals.
Main Methods:
- A retrospective cohort study design.
- Inclusion of 311 patients with HbSS and 167 patients with HbSC from birth.
- Longitudinal data collection on gallstone development and clinical outcomes.
Main Results:
- Gallstones developed in 96 patients with HbSS and 18 patients with HbSC.
- The majority of gallstone cases in both groups did not necessitate surgical intervention.
- Only 7 patients with HbSS experienced specific symptoms requiring cholecystectomy.
Conclusions:
- Gallstone formation is highly prevalent in both HbSS and HbSC disease.
- Despite high prevalence, symptomatic gallstones requiring cholecystectomy are infrequent in these cohorts.
- SCD patients with gallstones generally have low morbidity from this complication.
Abstract:
The prevalence, incidence, risk factors, clinical associations, and morbidity of gallstones were studied in 311 patients with homozygous sickle cell disease and 167 patients with sickle cell-hemoglobin C disease in a cohort study from birth. Gallstones developed in 96 patients with homozygous sickle cell disease and 18 patients with sickle cell-hemoglobin C disease; specific symptoms necessitating cholecystectomy occurred in only 7 patients with homozygous sickle cell disease.
