Insights
Sickle cell disease (SCD) in Kenyan children shows severe anemia and liver issues, similar to developed nations. However, enlarged spleens persist longer in this East African population.
Area of Science:
- Hematology
- Pediatrics
- Global Health
Background:
- Sickle cell disease (SCD) disproportionately affects sub-Saharan Africa, yet clinical data from children in this region are scarce.
- Understanding SCD's presentation in East Africa is crucial for improving patient outcomes.
- Previous research has not fully detailed the pediatric SCD experience in rural African settings.
Purpose of the Study:
- To describe the clinical characteristics of children with sickle cell disease in Kilifi, Kenya.
- To compare the clinical features of SCD in East African children with those in developed countries.
- To identify key health indicators and complications in pediatric SCD patients in a rural African setting.
Main Methods:
- Prospective observational study involving 124 children with SCD attending a specialist clinic in Kilifi, Kenya.
- Data collection included physical examinations (splenomegaly, hepatomegaly), malaria testing, hemoglobin levels, and liver function tests.
- Comparison with non-SCD controls and analysis of clinical manifestations across age groups.
Main Results:
- The study included 124 children with a median age of 6.3 years; 33% had splenomegaly and 20% had hepatomegaly.
- Mean hemoglobin was 73 g/l (vs. 107 g/l in controls), with elevated plasma bilirubin and aspartate aminotransferase.
- Hospital admission occurred in 39% of children, with two deaths; malaria prevalence was 6% during clinic visits.
Conclusions:
- Pediatric SCD patients in Kilifi exhibit anemia and liver dysfunction comparable to those in developed countries.
- Splenomegaly is a persistent clinical feature in children with SCD in this East African population.
- The study provides essential clinical data on SCD in rural East Africa, highlighting specific regional characteristics.
Abstract:
Globally, sickle cell disease (SCD) has its highest prevalence and worst prognosis in sub-Saharan Africa. Nevertheless, relatively few studies describe the clinical characteristics of children with SCD in this region. We conducted a prospective observational study of children with SCD attending a specialist out-patient clinic in Kilifi, Kenya. A total of 124 children (median age 6.3 years) were included in the study. Splenomegaly was present in 41 (33%) subjects and hepatomegaly in 25 (20%), both being common in all age groups. A positive malaria slide was found at 6% of clinic visits. The mean haemoglobin concentration was 73 g/l, compared to 107 g/l in non-SCD controls (P < 0.001). Liver function tests were elevated; plasma bilirubin concentrations were 46 micromol/l and aspartate aminotransferase was 124 iu/l. Forty-eight (39%) children were admitted to hospital and two died. Children with SCD in Kilifi have a similar degree of anaemia and liver function derangement to patients living in developed countries, but splenomegaly persists into later childhood. The prevalence of malaria was lower than expected given the prevalence in the local community. This study provides valuable data regarding the clinical characteristics of children living with SCD in a rural setting in East Africa.
