The Clinical Features of Sickle‐Cell/β Thalassaemia in Jamaica

S ummary . The clinical and haematological features of 56 Jamaican patients with sickle‐cell /β‐thalassaemia (S/Thal) are reviewed. The two types of S/Thal (with and without Hb A) had distinctive haematological and clinical characteristics. In general, the non‐Hb‐A type had evidence of lower haemoglobin levels, a more rapid haemolytic rate, and a more severe clinical course than the Hb‐A type.
