title: Benign obstetric history in women with sickle-cell anaemia associated with  -thalassaemia.
abstract: Two Ghanaian women with sickle-cell anaemia and alpha-thalassaemia were found to have an unusually benign obstetric history. In addition to two factors present which are known to moderate the clinical course of sickle-cell anaemia, good socioeconomic status and a relatively high Hb F level, it is suggested that alpha-thalassaemia may act among other things by lowering the haemoglobin concentration in the red cells and thereby lowering their tendency to sickle in vivo.
