[A case of a combination heterozygote with hemoglobin K Woolwich and hemoglobin C (Hb Kw/HbC) discovered in Bobo-Dioulasso (Burkina Faso)].

During a study on malaria in pregnant women in Burkina Faso, the authors gave a particular attention to the hemoglobin of a mother and her new-born child (blood of cord) and they noticed an hemoglobin migrating before the HbA which was identified by isoelectric focusing (IEF). The child is a composite HbK/HbC heterozygote. A survey was carried out to check the transmission of such a K Woolwich hemoglobin within the family of the mother. Out of 40 people, 17 got HbKw. A noticeable anemia was found in HbKw/HbC heterozygote. The authors tried to identified a possible thalassemia. There was little probability for an association of a minor alpha-thalassemia in the absence of Bart's hemoglobin in the blood of the cord (IEF test) and there was no associated beta-thalassemia.
