SICKLE CELL ANAEMIA AND MALARIA

Sickle Cell Anaemia and Malaria

Sickle cell anaemia is a major chapter within haemolytic anaemias; at the same time, its epidemiology is a remarkable signature of the past and present world distribution of Plasmodium falciparum malaria. In this brief review, in keeping with the theme of this journal, we focus on the close and complex relationship betweeen this blood disease and this infectious disease. On one hand, heterozygo...

Sickle Cell Disease and Sickle Cell Anaemia

Sickle cell haemoglobin (HbS) results from an autosomal recessively inherited mutation in which the 17th nucleotide of the beta globin gene is changed from thymine to adenine and the amino acid glutamic acid is replaced by valine at position 6 in the beta globin chain. [1, 2]Sickle cells have a reduced deformability and are easily destroyed, causing occlusion of the microcirculation and a chron...

Systemic lupus erythematosus and sickle-cell anaemia.

The buccal route does not have any disadvantages when compared to the oral route of prostaglandin administration. The incidence of vomiting (25%) described for the oral route by other workers is similar.2 3 The buccal route also has the advantages of oral drug administration. These are staff convenience and patient comfort, the latter being without the discomfort of an intravenous infusion and ...

Sickle cell anaemia and the NBT test.

Patients with sickle cell anaemia have an increased susceptibility to bacterial infections Previous reports of false-negative nitro blue tetrazolium (NBT) tests in the presence of bacteria infection and of a faulty phagocytic response following stimulation in vitro have suggested the possibility of polymorphonuclear dysfunction in certain patients with sickle cell anaemia. In the present study ...
