Insights
Sickle cell anemia (SCA) in The Gambia primarily affects children with mild to moderate disease. Key factors influencing severity include gender, complications like painful crises, and hematologic markers, highlighting the need for early diagnosis and treatment.
Area of Science:
- Pediatric Hematology
- Genetics
- Public Health
Background:
- Sickle cell anemia (SCA) is a major health issue in sub-Saharan Africa, yet data on clinical severity and predictors in The Gambia are scarce.
- Understanding disease burden in Gambian children with SCA is crucial for effective management and public health strategies.
Purpose of the Study:
- To assess patterns of clinical severity among children with SCA in The Gambia.
- To identify factors associated with disease severity in this pediatric population using a validated scoring system.
Main Methods:
- A hospital-based cross-sectional study enrolled 164 children (1-18 years) with confirmed sickle cell anemia (HbSS).
- Clinical and demographic data were collected, and disease severity was assessed using the Adegoke and Kuti scoring system.
- Statistical analyses included chi-square tests, t-tests, and correlation analysis to explore associations between severity and clinical variables.
Main Results:
- The majority of children presented with mild (67.1%) or moderate (31.7%) SCA; only 1.2% had severe disease.
- Significant associations with higher disease severity were found for female gender (P=0.028), frequent painful crises, hospitalizations, blood transfusions, low packed cell volume, and elevated white blood cell counts.
- Acute chest syndrome was the most common complication (34%); children on hydroxyurea typically had more severe disease, indicating its use in advanced cases.
Conclusions:
- Most Gambian children with SCA experience mild to moderate disease, with severity linked to gender, complications, and hematologic parameters.
- The findings emphasize the importance of early diagnosis via neonatal screening and improved access to hydroxyurea and comprehensive care.
- Further research into genetic modifiers could personalize SCA management in The Gambia.
Abstract:
Sickle cell anemia (SCA) remains a significant cause of morbidity and mortality in sub-Saharan Africa. In The Gambia, limited data exist on the clinical severity and predictors of disease burden in affected children. This study aimed to assess severity patterns and identify factors associated with disease severity among children with SCA using a validated clinical scoring system. A hospital-based cross-sectional study was conducted at the Pediatric Hematology Clinic of Edward Francis Small Teaching Hospital, Banjul. One hundred sixty-four children aged 1-18 years with confirmed HbSS were enrolled. Clinical and demographic data were collected using a structured proforma, and disease severity was assessed using the Adegoke and Kuti scoring system. Data were analyzed with SPSS version 20. Associations between severity and clinical variables were explored using chi-square tests, t-tests, and correlation analysis. Among the 164 participants, 67.1% had mild disease, 31.7% moderate, and 1.2% severe. The mean age was 8.43 ± 4.19 years, and the male-to-female ratio was 1.34:1. Gender was significantly associated with disease severity (P = 0.028). Early age at diagnosis showed a non-significant trend toward higher severity. Painful crises, hospitalizations, and blood transfusions were significantly associated with greater severity (P < 0.001). Laboratory markers such as low packed cell volume and elevated white blood cell counts also correlated with higher severity. Acute chest syndrome was the most frequent complication (34%). Children on hydroxyurea tended to have higher severity scores, reflecting that the medication was typically initiated in those with more severe disease. Most Gambian children with SCA in this cohort exhibited mild to moderate disease. Clinical severity was significantly associated with gender, frequency of complications, and select hematologic parameters. The findings underscore the need for early diagnosis through neonatal screening and improved access to hydroxyurea and comprehensive care. Further research into genetic modifiers may enhance individualized disease management in this setting.
