One hundred years of sickle cell disease.
The first formal report of sickle cell disease occurred 100 years ago. This review traces the early historical reports, the evolution of understanding of the genetics, the molecular and chemical basis of sickle haemoglobin, and the advances made over the last 30-40 years in improving the management. Newborn screening and close follow-up, especially early in life, has significantly improved survival but these advances require resources and sophisticated infrastructure. In sub-Saharan Africa over 250 000 births annually suggest that these advances are unlikely to be implemented within the foreseeable future. Prevention of the disease where possible, could reduce the numbers of new patients allowing better facilities for the care of others. As the disease results from the inheritance of abnormal haemoglobin genes from both parents, it is eminently preventable. The unanswered question, whether genotype detection and counselling will influence reproductive decisions, is currently being addressed by a project in central Jamaica.
