HP and malaria: Haptoglobin phenotypes and genotypes have been variously reported to be associated with a range of disease conditions, reviewed by McDermid et al [2], including viral load and mortality in HIV [3], [4], [5], Chaga's disease [6] diabetes-associated cardiovascular disease [7], [8], diabetes [9], gestational diabetes [10] and in some studies, susceptibility to malaria [4], [11], [12], [13], although other studies have not reported such an association [14], [15].
