Early deaths in Jamaican children with sickle cell disease
Insights
Early diagnosis of sickle cell (SS) disease in Jamaican infants shows 87% two-year survival. Prompt treatment of complications like splenic sequestration and pneumococcal infection is crucial for reducing mortality in these children.
Area of Science:
- Pediatrics
- Hematology
- Genetics
Background:
- Sickle cell disease (SCD) is a group of inherited red blood cell disorders.
- Homozygous sickle cell (SS) disease and sickle cell-haemoglobin C (CS) disease are common hemoglobinopathies.
- Neonatal diagnosis is critical for managing SCD complications.
Purpose of the Study:
- To evaluate two-year survival rates in Jamaican children diagnosed at birth with SS disease, CS disease, and normal controls.
- To identify the primary causes of mortality in infants with SS disease.
- To emphasize the importance of close post-neonatal observation for SCD management.
Main Methods:
- Retrospective survival analysis of Jamaican children diagnosed neonatally.
- Comparison of survival rates between SS disease, CS disease, and normal control groups.
- Analysis of mortality causes in SS disease patients.
Main Results:
- Two-year survival was 87% for SS disease, 95% for CS disease, and 99% for normal controls.
- Mortality in SS disease peaked between 6 and 12 months of age.
- Acute splenic sequestration and pneumococcal infections were the leading causes of death.
Conclusions:
- Neonatal diagnosis of hemoglobinopathies in Jamaica is associated with improved survival.
- Close monitoring following neonatal diagnosis is essential to prevent mortality from acute splenic sequestration and pneumococcal infections.
- Early intervention strategies are vital for improving outcomes in children with sickle cell disease.
Abstract:
In Jamaican children with homozygous sickle cell (SS) disease diagnosed at birth two-year survival was 87%, compared with 95% in children with sickle cell-haemoglobin C (CS) disease, and 99% in normal controls. Death among those with SS disease occurred most often between the ages of 6 and 12 months. Principal causes were acute splenic sequestration and pneumococcal infection. Neonatal diagnosis of haemoglobinopathies must be followed by close observation if mortality is to be reduced by early diagnosis and treatment of these complications.
