Outcome of Pediatric Patients With Sickle Cell Anemia Admitted With Fever: A Retrospective Single-Center Study

Year: 2024

Type: article

Abstract: BACKGROUND: Pediatric patients with sickle cell anemia (SCA) are known to have an increased susceptibility to infections, leading to a higher incidence of fever among this population. However, there is limited literature specifically focusing on the outcomes of pediatric SCA patients presenting to the emergency department (ED) or hospital with a primary diagnosis of fever. OBJECTIVES: The objective of this retrospective single-center study was to compare the characteristics of fever and associated symptoms among pediatric patients with SCA, and to investigate the risk factors associated with patients' outcomes and mortality in this specific population. PATIENTS AND METHODS: The study was conducted at the King Salman Medical City, Maternity and Children's Hospital, Medina, Saudi Arabia, during the period from 2017 to 2022. All pediatric SCA patients under the age of 14, who presented to the ED of the hospital during the study period with a primary diagnosis of fever, were included. The study collected and analyzed clinical, laboratory, treatment, complications, and outcome data of the patients using appropriate statistical methods, including logistic regression. RESULTS: A total of 57 children were included in the analysis. The mean age of the patients was 7.1 ± 4.3 years, with 26 males (45.6%) and 31 females (54.4%). Among the cases, 8 (14%) exhibited fever along with gastrointestinal symptoms, 18 (31.6%) presented with musculoskeletal symptoms, 5 (8.8%) showed neurological symptoms, and approximately half of the cases (45.6%) displayed respiratory symptoms along with fever. Logistic regression analysis identified several significant factors associated with complications in this sample, including a very low level of hemoglobin (Hb) (<7 g/dL) with an odds ratio (OR) of 14.5 (95% CI=1.03-222.3), ICU admission with OR of 14 (95% CI=1.03-186.8), and a hospital stay duration of more than 10 days (OR=11.5; 95% CI=1.10-121.3). Additionally, fever associated with neurological symptoms, neutrophilia, history of splenectomy, and male sex showed positive associations with complications among the studied patients, although not significant. CONCLUSION: This study provides valuable insights into the characteristics and outcomes of febrile pediatric patients with SCA. The findings highlight the importance of early recognition and management of fever in this vulnerable population, particularly when certain risk factors are present.
