Sickle cell-beta +-thalassaemia: a haematological and clinical study in Liberia.

Clinical and haematological features of 20 patients of several Liberian ethnic groups with sickle cell-beta +-thalassaemia are reported. Haemoglobin analysis showed increased Hb A2 values, high Hb A levels (median 25%), variable amounts of Hb F and a slight imbalance of non alpha/alpha globin chain synthesis ratios. The clinical and other haematological findings varied but the disease seems to run a relatively mild course in the majority of the patients.
