Background: Children with sickle cell disease (SCD) frequently present with acute pain. The abdomen, a common site of acute SCD-related pain, may be present in a variety of gastrointestinal (GI) pathologies. Limited data exist on prevalence and workup of abdominal pain in patients with SCD during acute pain events.
Objectives: Determine prevalence of GI symptoms, GI-specific evaluation and risks of hospitalization in children with SCD presenting to the emergency department (ED) or hospitalized with abdominal pain.
Methods: Retrospective study of children less than 21 years presenting to the ED or hospitalized with pain in our center over 2 years. Descriptive statistics were used to report clinical characteristics, frequency of GI symptoms, workup by age (<5 vs. ≥5 years), and genotype (sickle cell anemia [SCA] vs. non-SCA). Logistic regression models were used to identify risks associated with hospitalization.
Results: A total of 1279 encounters in 378 patients were analyzed; 23% (n = 291) encounters were associated with abdominal pain. More abdominal pain-associated hospitalizations occurred in older children, SCA, children with lower mean hemoglobin (8.7 ± 1.9 vs. 9.6 ± 1.6 g/dL, p < .001) and higher mean white blood cell (WBC) count (14.9 ± 6.6 vs. 13.2 ± 5.3 × 103 /μL, p = .02). We identified that less than 50% of patients presenting to the ED with abdominal pain received a GI-specific evaluation.
Conclusion: Children with SCD frequently present with abdominal pain and other GI symptoms, with limited GI evaluations performed. GI-specific evaluation may increase diagnosis of GI pathologies, rule out GI pathologies, and contribute to the limited knowledge of the abdomen as a primary site of SCD pain.
