Outcomes of Cholelithiasis Among Patients With Sickle Cell Disease: A Tertiary Care Center Experience.

Abstract

Sickle cell disease (SCD) is a significant health burden in Saudi Arabia that leads to chronic hemolysis with subsequent formation of cholelithiasis. The prevalence of cholelithiasis in the Middle East variesin patients with SCD. Theaim of our study was to determine the prevalence of cholelithiasis among SCD patients at a large tertiary care center, King Abdulaziz University Hospital, Jeddah, Saudi Arabia, where more than 300 patients with hemoglobinopathies were followed up. In this cross-sectional retrospective study conducted from May 2006 to May 2022, we reviewed 414 patients with SCD who were divided into two groups according to the presence or absence of cholelithiasis. Demographic data, SCD phenotype, splenectomy, cholecystectomy, and hydroxyurea were reviewed from the patient's medical records. They were analyzed to suggest a correlation between the incidence of cholelithiasis and the chances of cholecystectomy. A total of 414 patients with SCD were reviewed. The mean age of participants was 31 years (10-82), with 52% male. Patients with homozygous sickle hemoglobin (HbSS) constituted 73% of the cohort. The rest (26%) had HbS/β-thalassemia. Thirty-three patients (8%) had splenectomy done. Compliance with hydroxyurea was observed in 174 patients (42%). A total of 64.7% of patients had cholelithiasis (n=269), out of which 159 patients (59.1%) had cholecystectomy done. Surprisingly, a significant association was found between cholecystectomy and the use of hydroxyurea (p=0.003). Additionally, there was a significant association found between the development of cholelithiasis and increasing age (p=0.037). There was a high prevalence of cholelithiasis found in patients with SCD. It correlated significantly with high-age groups. Further research is warranted to confirm the relationship between hydroxyurea and cholelithiasis.
