ABSTRACT
There is evidence to suggest that persons possessing the sickle cell gene is protected against falciparum malaria. A University College of the West Indies Survey was conducted in Barbados to determine the incidence of the abnormal haemoglobins with particular reference to the sickling gene and the findings compared with those in Jamaica. The genital implications are discussed, particularly the role of sickle cell anaemia itself and the findings in people from other Caribbean islands included for comparison (AU)

Of 12 patients with aplastic crisis associated sickle-cell disease, eleven were children with sickle-cell anaemia, and one was an adult with sickle-cell haemoglobin-C disease. Ten of the cases were seen over a period of less than 7 months, and the syndrome may be commoner than has previously been supposed. Evidence is given to support the hypothesis that the distribution of sickle-cell and foetal haemoglobins in the erythrocytes in sickle-cell anaemia is not homogeneous. The fact that seven of the cases belonged to three families implies that infection may play an important aetiological role. This view is supported by the clinical presentation, and by the fact that one patient apparently had infectious mononucleosis. Bacterial and viral studies fail to demonstrate any aetiological agent in these cases (Summary)
