Abstract

Haptoglobin is an acute phase protein that scavenges haemoglobin in the event of intravascular or extravascular haemolysis. The protein exists in humans as three main phenotypes, Hp1-1, Hp2-2 and Hp2-1. Accumulated data on the protein's function has established its strong association with diseases that have inflammatory causes. These include parasitic (malaria), infectious (HIV, tuberculosis) and non-infectious diseases (diabetes, cardiovascular disease and obesity) among others. Phenotype-dependent poor disease outcomes have been linked with the Hp2-2 phenotype. The present review brings this association into perspective by looking at the functions of the protein and how defects in these functions associated with the Hp2 allele affect disease outcome. A model is provided to explain the mechanism, which appears to be largely immunomodulatory.
